Description

  The present invention relates to a three-dimensional parking apparatus used for parking an automobile.

  When exporting a car by ship, the car is first transported to a site called a motor pool, such as a wharf, where the car is parked and stored. And, a car is driven into a warehouse of an automobile transport ship anchored in a motor pool.

In general, since a motor pool is a terrain made on a wharf or the like, when a car is parked in the motor pool, it is arranged so as to be arranged vertically and horizontally.
Since the motor pool has a relatively large site area, it is possible to store and store a corresponding number of vehicles even if the vehicle is simply parked in a plane as described above. However, since there is a limit to the area of the motor pool, there is a limit to the number of cars that can be accommodated there.

  Therefore, in a motor pool with a limited site area, if you want to park more cars than if you plan to park the cars on a plane and use the site area more effectively, It means that you only have to park. For this purpose, it is conceivable to introduce a multi-story parking device in the motor pool.

  As a three-dimensional parking apparatus, for example, a two-stage parking apparatus in which a pallet on which an automobile is placed is moved up and down is widely known. That is, first, for example, when an automobile is placed on a pallet lowered to the ground level, the pallet is raised to a specified position. Then, another automobile is parked in the space formed on the lower side of the raised pallet. In this way, two cars can be parked with respect to the parking area of almost one car.

  In addition, as a three-dimensional parking apparatus capable of parking two vehicles in a three-dimensional manner, one having a configuration in which one vehicle is parked in the basement below the ground level and the other vehicle is parked on a pallet installed thereon. It has been. In this case, the pallet is moved up and down when the vehicle is taken in and out of the basement.

  And if such a three-dimensional parking apparatus is installed in a motor pool, the number of parking per unit area will increase, so the number of parking storages in the motor pool can also be increased.

In addition, the following patent documents can be mentioned regarding the above-mentioned three-dimensional parking apparatus.
JP 2000-129946 A JP-A-5-187144 Japanese Patent Laid-Open No. 6-272412

  Here, the pallet of the above-described multi-story parking apparatus has a considerable weight including its own weight, particularly in a state where the automobile is placed, so that it requires a certain force to raise and lower the pallet. Become. For this reason, it is normal to use electric power for raising and lowering the pallet. That is, a pump, a motor, etc. are driven with electric power, a hydraulic cylinder or a chain block is operated, and a pallet is raised / lowered.

The motor pool is originally a place for managing many automobiles, and several tens to hundreds of cars can be parked on a plane.
If a multi-story parking device such as that described above is installed in the motor pool, for example, one multi-story parking device will be installed for every parking area of one vehicle. Even so, there will be a correspondingly large number depending on the number of cars that can be parked. And an electric facility will be assembled in the site of a motor pool so that these three-dimensional parking apparatuses may be driven by electric power.
In this way, it is not preferable to equip an electrical facility for a multi-story parking apparatus facility on a site such as a motor pool because it is very costly.

Therefore, it can be said that a multi-story parking apparatus particularly suitable for installation in a motor pool is required that does not require an electrical facility for operations such as raising and lowering a pallet.
In addition, in patent document 1, although the raising / lowering of a pallet is performed using the drive force of the drive wheel of the motor vehicle mounted on the pallet, the structure of the multilevel parking lot which does not require an electric power facility is shown, It can be said that such a mechanism for raising and lowering the pallet is complicated. Considering that the multi-story parking apparatus is installed in an outdoor environment, it is necessary from the viewpoint of maintenance and the like that the mechanism be as simple as possible. If the mechanism is simplified, the manufacturing cost can be reduced accordingly.
Further, Patent Document 3 discloses a seesaw type multi-story parking device, and describes that a pallet (parking table) that moves up and down by a seesaw-like operation can be manually moved. As described above, since the pallet has a corresponding weight, it is actually difficult to simply move it manually. However, in Patent Document 3, it is actually possible to move manually by any technique. There is no description as to whether this is possible.

  Therefore, an object of the present invention is to provide a three-dimensional parking apparatus that does not use electric power for movable parts such as pallets and the like and has a structure that is as simple as possible and practical enough.

Therefore, as the present invention, the base part, the support attached to the base part, and the support can be changed between a standing state standing at a specified position and a fallen state falling down at a specified position. In this way, when the vehicle is not parked at the upper specified position with the column support portion attached to the base portion and the position pivotally supported by the standing column as the fulcrum, the rear end is inclined so that it is almost grounded. When the vehicle is parked at the specified position in the upper stage, the seesaw motion is enabled so that the rear end side is lifted. Connect one end of the in-vehicle mount and the hydraulic cylinder for buffering the seesaw motion to the fixed first connecting portion of the in-vehicle mount and connect the other end of the hydraulic cylinder to the base. A hydraulic cylinder coupling mechanism portion that is attached so as to be coupled to a second coupling portion that is slidable along a side surface direction of the portion, and one end of which is rotatable with respect to the second coupling portion with respect to the base portion It is attached and the other end is rotatably attached to the fulcrum, so that when the support column is changed from the standing state to the tilted state, the second connecting part is pushed backward to give a force to slide, When the vehicle is transitioned from the standing state to the standing state, a seesaw type multi-story parking apparatus is provided that includes a connecting member adapted to apply a sliding movement by pulling the second connecting part forward. .

In the seesaw type multi-story parking apparatus having the above-described configuration, the on-vehicle platform is pivotally supported by a support so that the seesaw motion can be performed. And the seesaw movement is as follows.
That is, when it is assumed that the vehicle is not parked on the vehicle mount, the vehicle mount is inclined such that one end of the vehicle mount is substantially at the ground level. In this state, it is possible to place the vehicle on the vehicle mount base as if the vehicle is approaching from the ground.
And, when it is assumed that the car is parked on the vehicle mount, the weight of this car is added, so that the center of gravity changes so that the other end side of the vehicle mount tilts to the ground. The one end portion ascends from the ground level. That is, as a result of obtaining an operation of raising the vehicle-mounted gantry, it is possible to obtain a posture state in which two-dimensional parking can be performed as a seesaw type parking device.

From this, the three-dimensional parking apparatus of the present invention uses a seesaw motion to raise and lower the in-vehicle gantry, and the seesaw motion further includes the weight of the in-vehicle gantry itself and the in-vehicle gantry when the automobile is placed. It is obtained by moving the center of gravity by the weight of the. That is, no electric power is used for raising and lowering the vehicle mount.
The structure for obtaining the seesaw operation described above includes an in-vehicle gantry and a support column that pivotally supports the in-vehicle gantry so that the seesaw operation can be performed. The structure which adds the hydraulic cylinder which buffers the force when an in-vehicle mount moves.

In this way, the present invention does not require electric power as a three-dimensional parking apparatus that enables three-dimensional parking of an automobile by raising and lowering the on-vehicle platform. And the raising / lowering of the vehicle-mounted frame which does not require electric power in this way utilizes the weight of the vehicle-mounted frame or the weight of the automobile mounted on the vehicle-mounted frame. That is, a large force required for lifting the vehicle frame, since it is that obtained by the weight of the vehicle frame and car are weighs correspondingly its feasibility is also reliable.
In addition, the hydraulic cylinder reduces the force applied when the in-vehicle stand performs the seesaw operation, so the seesaw operation is slow, so safety is high, and it is placed on the in-vehicle stand. Since no impact is given to the automobile and the three-dimensional parking apparatus, the fracture resistance is also good.

  The best mode for carrying out the present invention (hereinafter referred to as “embodiment”) will be described below. The seesaw type multi-story parking apparatus according to the present embodiment is an example of a case where the seesaw type parking apparatus is used in a so-called motor pool in which a car before being loaded on a ship is parked and stored in order to transport and export the car. Suppose that As an example of the type of automobile to be parked in the seesaw type multi-story parking apparatus of the present embodiment, a case where the truck is in a state before the loading platform is attached is given as an example.

FIG. 1 schematically shows the basic configuration of the seesaw type multi-story parking device 1 (hereinafter also simply referred to as “semi-semi-parking device”) of the present embodiment, and the work procedure for parking a truck is as follows. It shows with the operation of the multi-story parking apparatus 1.
The multi-story parking apparatus 1 of the present embodiment includes, for example, an upper pallet (on-vehicle mount) 2, a base portion 3, and a tiltable column 4 as illustrated. However, in this drawing, the basic structure of the multi-story parking apparatus 1 is schematically shown, and as will be understood from the following description, actually, it is configured with other parts and parts. It is. Each part shown in this figure also has a more complicated shape and structure in practice.
The base portion 3 is formed by combining frames made of iron material and is installed with respect to the ground. The retractable support columns 4 are provided one by one so as to be paired with respect to the left and right frame sides of the base portion 3. For example, at the position shown in the drawing, the lower support column 4 rotates below the support column. The shaft rx2 is attached so as to be supported. Thereby, the collapsible support | pillar 4 can be inverted. However, as will be described later, the position of the retractable support column 4 is restricted so as not to rotate to the front side (the left side of the paper) of the multi-story parking device 1. Inverting is possible between the state of falling in the direction.

  The upper pallet 2 serves as a gantry (on-vehicle gantry) on which a truck to be parked is placed. The upper pallet 2 is pivotally supported by a rotation shaft rx1 on the upper side of the tiltable support column 4 on the left and right sides thereof. In other words, the upper pallet 2 is capable of seesaw motion with the rotation axis rx1 as a fulcrum in a state where the tiltable column 4 is upright as shown in FIGS. 1 (a), 1 (b), and 1 (c). It is attached.

In the multi-story parking apparatus 1 having such a basic structure, the position of the fulcrum (rotation axis rx1) in the upper pallet 2 is located at the front end by a predetermined length with respect to the center position of the length from the front end to the rear end. Is set to That is, in the normal state, the eccentric fulcrum position is set such that the center of gravity is biased toward the rear end side.
For this reason, when the track is not placed, the center of gravity is located on the rear end side rather than the front end side with respect to the rotation axis rx1 serving as a fulcrum. In other words, a force that moves the rear end side to tilt downward acts on its own weight. For this reason, for example, as shown in FIG. 1A, the rear end portion is inclined (first state) so that it is substantially at the ground level.

When the multi-story parking apparatus 1 according to the present embodiment performs multi-story parking of the truck, as shown in FIG. 1A, the truck (chassis) from the rear side with respect to the upper pallet 2 whose rear end side is at the ground level. (Cabin) 100 is advanced as it moves forward.
The truck 100 is in a state in which the loading platform is not attached. Therefore, as shown in the drawing, the truck 100 includes only the front cockpit portion 101 and the chassis portion 102 behind the front cockpit portion 101. Thus, in the truck 100 with no loading platform attached, the weight balance is heavier in the cockpit portion 101 than in the chassis portion 102.

  Then, if the rear wheel of the truck 100 is also placed on the upper pallet 2 and further enters a specified position range in the upper pallet 2, the cockpit portion 101 of the truck 100 is mainly located in front of the upper pallet 2. Side weight will be added. Thereby, in the upper pallet 2, the center of gravity moves toward the front end side with respect to the fulcrum (rx1).

For this reason, as shown by arrows A and B in FIG. 1B, the upper pallet 2 moves so that the front end side is inclined downward (the rear end is upward).
Although not shown here, the upper pallet 2 is positioned such that the upper pallet 2 is maintained at a predetermined angle with respect to the horizontal plane, so that the upper pallet 2 is in a position state as shown in FIG. Will be stationary. Here, in actuality, the upper pallet 2 is in a state in which the front side is inclined downward by a predetermined angle from the horizontal plane. This is because the truck 100 parked on the lower side (lower stage) of the upper pallet 2 as will be described later is placed between the rear end side of the upper pallet 2 and the ground so that the truck 100 can easily enter. Considering that it is possible to obtain a height higher than required in accordance with the entrance portion of the.

In this state (second state), as can be seen from FIG. 1B, the track 100 is placed on the upper pallet 2 and is positioned at a predetermined height. This position is the raised position of the upper pallet 2. That is, FIG. 1B shows a state in which the upper pallet 2 has completed raising to the specified ascent position with the truck 100 parked.
In the state shown in FIG. 1B, a space having a certain height or more is obtained between the ground level and the upper pallet 2. This space is the lower parking area.

  In order to park the truck 100 in this lower parking area, in this case, as shown in FIG. 1C, the truck 100 is moved backward from the rear side (the right side of the drawing) of the multi-story parking apparatus 1. Then, the vehicle is allowed to enter with the rear side of the truck 100 facing forward, and is stopped when a predetermined position is reached. The state shown in FIG. 1C is a state in which the trucks 100 are properly parked with respect to the upper and lower stages in the multi-story parking apparatus 1 of the present embodiment.

In order to move the parked truck 100 from the multi-story parking device 1, first, the lower track 100 is moved forward from the state shown in FIG. That's fine.
Then, as the three-dimensional parking apparatus 1, as shown in FIG.1 (b), although the lower parking area is vacant, the truck 100 is mounted in the upper pallet 2 in a predetermined ascending position. It becomes a state.
From this state, the truck 100 placed on the upper pallet 2 is moved backward little by little. That is, it advances in the right direction on the paper. As the truck 100 moves backward, the heavy cockpit portion 101 in the truck 100 moves to the rear end side of the upper pallet 2, and accordingly, the upper pallet 2 as a seesaw is moved. The center of gravity also moves toward the rear end. Then, if the truck 100 moves backward to a position beyond a certain specified range and the center of gravity moves to the rear end side from the fulcrum (rotation axis rx1), the upper pallet 2 moves the rotation axis rx1. The fulcrum moves so that the rear end side is downward and the front end side is upward. That is, in FIG. 1B, it moves in the direction opposite to the arrows A and B. Then, if it is assumed that the rear end side of the upper pallet 2 has reached the ground level, the movement stops.

  Therefore, from this state, the truck 100 placed on the upper pallet 2 is moved backward. As shown in FIG. 1A, this can be seen as a state where the truck 100 does not move forward but is moving backward while moving backward. When the truck 100 is completely lowered from the upper pallet 2, the multi-story parking apparatus 1 is in a state where no truck is parked on the upper stage or the lower stage.

In the three-dimensional parking apparatus 1 of the present embodiment, when the truck is not parked at all as described above, the upper pallet 2 is mounted on the base portion 3 as shown in FIG. And can be stored in a state that is almost at the ground level.
In order to achieve such a state, the inclinable support column 4 is made to be substantially horizontal by being tilted to the rear side of the three-dimensional parking apparatus 1. Since the upper pallet 2 is attached to the tiltable support column 4 at the position of the rotation axis rx1, the upper pallet 2 can be moved as shown in FIG. It can be set as the state which overlaps with the base part 3. FIG. In such a state, the truck 100 can be moved so as to pass over the multi-story parking apparatus 1.

  In the present specification, the state of the multi-story parking apparatus 1 shown in FIG. 1D is also referred to as a storage state when the upper pallet 2 is in the storage position. In addition, as shown in FIGS. 1A, 1B, and 1C, the state where the upper pallet 2 is in the range from the lowered position to the raised position is the state when the multi-story parking apparatus 1 is parked by entering the truck. Therefore, it is also called a parking available state.

As understood from the description of FIG. 1 above, in the multi-story parking apparatus 1 of the present embodiment, first, as shown in FIG. it can. In this case, the type of the car to be parked is the truck before the loading platform is mounted, and the difference in height between the cockpit portion 101 and the chassis portion 102 is large. Therefore, only the chassis portion 102 of the truck 100 is placed below the upper pallet 2 on the lower side. I am trying to sneak into. Therefore, in this case, in the upper track 100 and the lower track 100 parked in the multi-story parking apparatus 1, the chassis portions 102 overlap each other in the vertical direction.
In other words, in the installation area of the one-dimensional parking device 1, two trucks can be accommodated and parked, and in the length direction of the truck,
One truck + one cockpit size is enough.

  Specific size settings for the main components of the multi-story parking apparatus 1 will be described later. For example, when the truck 100 is of a two-ton class of a certain predetermined size, it is shown in FIG. Thus, the length L from the front end portion of the upper track 100 to the front end portion of the lower track 100 in a state where the chassis portions 102 of the upper / lower tracks 100, 100 are substantially vertically overlapped is, for example, Fits around 8000mm. For example, in the case where a truck is placed flat like a conventional motor pool, when two trucks are parked, 6840 mm × 2 = 13680 mm, and a margin of about 1500 mm is necessary for this. Therefore, depending on the present embodiment, the length required for parking for two vehicles is significantly shorter. As a result, for example, the number of cars that can be parked in the motor pool can be increased as exemplified below.

FIG. 2 shows a comparison between the embodiment and the conventional case where the truck 100 is parked in the motor pool. FIG. 2A shows the case of the embodiment, and FIG. 2B shows the conventional case.
Here, it is assumed that the motor pool shown in FIGS. 2A and 2B has a parking site having an area of 30 m in length and 108 m in width. In addition, there is a passage having a width of 15 mm on the front side of the parking site. Trucks transported to the motor pool can be carried into the parking lot by driving through this passage. The track size here is the same as in the above example.

First, in the prior art, trucks are arranged two-dimensionally without parking, but with the above-mentioned truck size, as shown in FIG. Can be arranged in a row. Since the length of the track is 6840 mm, which is less than 7000 mm, it is possible to arrange 4 units in calculation, but as a practical matter, if 4 units are accommodated in one row, the front and back will be too clogged, Since there is a high possibility of contact and breakage, three units are arranged here in accordance with such actual circumstances.
The width of the parking lot occupied by the row where the three trucks are arranged is 3.1 m.
In this way, if 3 units are arranged for each row, 34 rows can be made for a width of 108 m. Accordingly, the truck 100 can accommodate a maximum of 3 × 34 = 102 vehicles.

Subsequently, as the present embodiment shown in FIG. 2 (a), since the occupation length when one-dimensional parking of the multi-story parking device 1 is about 8000 mm as described above, the vertical width is 30 m. On the other hand, three three-dimensional parking apparatuses can be arranged. Therefore, the number of trucks that can be parked per row is 3 × 2 = 6. However, by installing the multi-story parking apparatus 1, in this case, the width occupied by one row becomes as wide as 3.6 m.
Still, if the width of 108m of the parking lot is allocated at 3.6m, 30 rows can be made, so overall, it will be possible to accommodate 6 x 30 = 180 units, which is larger than conventional ones. The possible number will be increased by 72. By the way, the number of the multistory parking apparatus 1 installed in this case is 3 × 30 = 90 because there are three in one row.

In addition, when the multi-story parking apparatus 1 is arrange | positioned as shown to Fig.2 (a), parking for every row is performed as follows.
In the case of FIG. 2 (a), the lower side of the paper is the back side in the parking site, and the truck cannot pass further beyond this. For this reason, the truck is brought in from the front side of the parking site on the upper side of the page. First, among the three-dimensional parking apparatuses 1 for one row, the innermost parking apparatus 1 is set in a parking-enabled state, and two trucks in front are set in a storage state so that a truck can pass. In this state, first, the truck is advanced from the aisle side to enter, parked on the upper pallet 2 of the innermost parking device 1, and then the truck is moved backward to enter. Park in the lower part of the parking device 1.
After that, the second three-dimensional parking device 1 from the back is set in a state where parking is possible, and the truck is entered from the aisle side as described above to park in the upper and lower tiers, and the frontmost three-dimensional parking device 1 can be parked. As a state, as described above, the truck is entered from the passage side and is parked at the upper stage and the lower stage. This means that 6 cars can be parked for one row.
In addition, in order to take out the truck parked in this way from the multi-story parking apparatus 1, the order of the multi-story parking apparatus 1 in the center and the back is sequentially increased from the nearest multi-story parking apparatus 1 in the reverse order. Then just drop the truck.

And as the three-dimensional parking apparatus 1 of this Embodiment, as can be understood from the description with reference to FIG. 1, the upper pallet 2 is in a parkable state, and the truck to be placed thereon moves forward / backward. The seesaw operation is performed by moving the center of gravity obtained by doing this, and this is obtained as an operation of raising and lowering the upper pallet 2.
That is, the multi-story parking apparatus 1 according to the present embodiment does not require electric power to move the upper pallet 2 that has a corresponding weight.

For example, Patent Document 3 discloses a three-dimensional parking apparatus 1 using a seesaw operation. However, from the disclosed contents, there is a description that the parking table is lifted and lowered in an environment that does not require electric power by using the center of gravity movement of the seesaw by the forward / backward movement of the automobile placed on the pallet (parking table). Not. Although it has been described that it can be raised and lowered manually, a configuration for manually raising and lowering a heavy parking table safely and reliably using a seesaw operation is not disclosed.
On the other hand, in the present embodiment, in order to obtain the seesaw operation, the weight of the upper pallet 2 itself and the weight of the truck (automobile) placed thereon are used. The raising and lowering operation of the pallet 2 can be reliably obtained. Even as a result of the actual verification, the lifting operation of the upper pallet 2 shown in FIG. 1 is reliably obtained.
Moreover, although mentioned later for details, from the attitude | position state of the multi-story parking apparatus 1 shown to Fig.1 (a), the tiltable support | pillar 4 is brought down and it is set to the state shown in FIG.1 (d), and conversely FIG. Even when the retractable support column 4 is raised from the state shown in d) to the state shown in FIG. 1A, in this embodiment, the retractable support column 4 is moved without using electric power. . Including the above, the multi-story parking apparatus 1 of the present embodiment is configured such that no part is directly driven by electric power to move the movable part.

For this reason, it is not necessary to provide power equipment in particular as the multistory parking apparatus 1 of the present embodiment is installed. As a result, first, the labor for installing the equipment is saved, and the cost can be reduced as the power equipment becomes unnecessary.
This merit becomes particularly remarkable when a large number of three-dimensional parking apparatuses 1 are installed in a motor pool, for example, as shown in FIG. In other words, if it is a three-dimensional parking device that requires electric power facilities, it will be necessary to perform a considerably large-scale construction for providing electric facilities in the entire motor pool, and the labor and cost required for that will be considerable. However, if the multi-story parking apparatus 1 of this Embodiment is installed, such a problem will not arise at all.

  Moreover, about the multi-story parking apparatus 1 of this Embodiment, it can also be said that there is no movable part driven by electric power that the structure becomes simple. As will be apparent from the specific structure example described later, the multi-story parking device 1 of the present embodiment is actually simple in structure, but normally operates as a multi-story parking device. If the structure of the apparatus is simple, it can be said that, for example, it is resistant to breakdowns, maintenance is easy, and manufacturing costs can be reduced.

Further, as will be described in detail later, when the upper pallet 2 moves up and down, the hydraulic cylinder cushions the force generated when the upper pallet 2 moves. Performed smoothly at speed.
Thereby, as this Embodiment, the impact more than necessary is not given with respect to the truck mounted in the upper stage pallet 2, and the three-dimensional parking apparatus 1 itself. This also ensures high safety.

Hereinafter, specific configuration examples of the multi-story parking apparatus 1 according to the present embodiment will be described. First, the overall structure of the multi-story parking apparatus 1 will be described with reference to FIGS.
FIG. 3 shows a state where the multi-story parking apparatus 1 is located at a specified lowered position as a side view. This corresponds to the state shown in FIG. 1A in FIG. Moreover, in FIG. 3, the front-end part side of the multi-story parking apparatus 1 is the left side of the paper surface, and the rear-end part side is the right side of the paper surface. The same applies to the remaining FIGS. 4 to 7.
FIG. 4 shows a state in which the upper pallet 2 is at a specified ascending position as a side view of the entire multi-story parking apparatus 1. 1 corresponds to the state shown in FIG. 1 (b) or FIG. 1 (c).
FIG. 5 shows the housed state as a side view of the entire multi-story parking apparatus 1. FIG. 1 corresponds to the state shown in FIG.
FIG. 6 is a plan view of the multi-story parking apparatus 1. Also, in the same FIG. 6, a cross-sectional view of the upper pallet 2 taken along the line AA in the plan view is shown on the left side of the drawing.
FIG. 7 is a plan view showing only a portion as the base portion 3 in the multi-story parking apparatus 1.

As the three-dimensional parking apparatus 1 of the present embodiment, first, the base portion 3 is arranged on the ground. As shown in FIG. 7, the basic structure of the base part 3 is a pair of base frames 3a and 3a that are positioned on both the left and right sides, and the base frames 3a and 3a are kept at a predetermined distance. It becomes a frame part which consists of connecting frames 3b, 3b, 3b to be connected.
Then, as shown in FIG. 7 and FIGS. 3 to 5, the step filling block 18 is provided on the connecting frame 3 b on the front end side so that the end thereof is placed. The step filling block 18 fills the step between the front end portion of the upper pallet 2 and the ground when the truck 100 passes over the multi-story parking apparatus 1 as shown in FIG. Is intended to be able to descend from the upper pallet 2 to the ground in a state where the shock is reduced as much as possible.

In addition, as shown in FIGS. 7 and 3 to 5, a connecting plate 21 is fixedly attached by welding or the like to each rear end side of the base frames 3 a and 3 a in this case. Ground tire rails 13 and 13 are attached to each of the plates 21. As shown in FIG. 3, when the retractable rail portion 2 f attached to the rear end portion side of the upper pallet 2 is tilted, the rear end of the retractable rail portion 2 f is placed on the ground tire rail 13. It becomes. By making this state, as shown in FIG. 1 (a), when the truck 100 is advanced and placed on the upper pallet 2, the tire can be smoothly placed on the upper pallet 2 from the ground. I can do it.
Depending on the condition of the ground and the like, the tires of the truck 100 can be smoothly placed on the upper pallet 2 with the rear end of the retractable rail 2f being in direct contact with the ground even without the ground tire rails 13 and 13. In such a case, the ground tire rails 13 and 13 may be removed. Moreover, since the connection board 21 is for integrating the ground tire rails 13 and 13 with the base frame 3a of the base part 3, this connection board 21 may also be removed.

  Further, as shown in FIGS. 7 and 3 to 5, a guide rail 7 is fixedly attached to an upper surface portion slightly behind the center of the base frames 3 a and 3 a. As shown in FIGS. 3 to 5, a slide member 8 is attached to the guide rail 7 so as to be slidable along the front-rear direction. The slide operation of the slide member 8 along the guide rail 7 is related to the seesaw-like lifting operation of the upper pallet 2, which will be described later.

  Further, as shown in FIGS. 7 and 6, spring boxes 16 and 16 are provided at predetermined positions on the side surfaces of the base frames 3a and 3a, respectively. As will be described later, springs are built in the spring boxes 16 and 16, and the tension of the spring causes the retractable support column 4 to change from the state shown in FIG. 5 to the state shown in FIG. 3, for example. Helps you get started.

On the upper surfaces of the base frames 3a and 3a of the base portion 3 formed as described above, the two supporting column support plates 5A and 5B are attached in an upright state. The column support plates 5A and 5B are also shown in FIGS. 3 to 6, but this portion is shown in an enlarged manner in FIG.
And it attaches so that the fallable support | pillar 4 may be fitted between this support | pillar receiving plate 5A, 5B, but this fallable support | pillar 4 is hold | maintained in the state which can be rotated by the rotating shaft 5b in the lower side. It is attached in such a way as to be (supported). The rotating shaft 5b corresponds to the rotating shaft rx2 in FIG.

The guard column 6 is positioned in front of the column support plates 5A and 5B as shown in FIGS. This guard column 6 is also fixedly attached to the base frames 3b and 3b. A reinforcing portion 6a is attached to a portion where the lower front side of the guard column 6 and the base frame 3a are orthogonal to each other. This reinforcing portion 6a reinforces the mounting strength of the guard column 6 provided upright on the base frame 3a.
It can be seen that the tiltable support column 4 that is rotatably mounted as described above is further restricted from rotating in the forward direction from a state where it is assumed to be upright by contacting the guard support column 6. . Therefore, the collapsible support column 4 moves in a range of an upright state and a state in which the tiltable column 4 is tilted so as to be rotated and moved to the rear side. That is, it can be inverted in a range of approximately 90 ° between the upright state and the rearward state.

As will be described in detail later, the guard column 6 includes a chain block 30 that moves when the tiltable column 4 is raised and operates, and a wire that is connected to the spring of the spring box 16. The The guard column 6 is provided to cover these items.

As shown in FIGS. 3 to 6, the upper pallet 2 is first formed into an outer frame shape by a pair of left and right side base frame portions 2a, 2a, a front base frame portion 2k-1, and a rear base frame portion 2k-2. Is formed. In addition, a predetermined number of reinforcing frames 2i, 2i,... Are attached so as to pass between the side base frame portions 2a, 2a.
Furthermore, in order to further reinforce the portion on which the truck tire is mounted, a predetermined number of front and rear direction frame members 2j-1 and horizontal direction frame members 2j-2 are combined and attached in a lattice shape. The mesh plate 2g is placed on the portion where the longitudinal frame member 2j-1 and the lateral frame member 2j-2 are formed in a lattice shape, that is, on the portion where the truck tire is placed as described above. I try to lay it.

  Further, side guide rails 2c and 2c having a predetermined height are attached to the upper surfaces of the side base frame portions 2a and 2a along the front-rear direction in order to prevent the tire from being removed.

  Further, ground receiving members 2g and 2g are attached to the rear end sides of the side base frame portions 2a and 2a, respectively. As shown in FIG. 3, the ground receiving members 2g and 2g are arranged so that the roller 2h attached to the lower end of the upper pallet 2 is in contact with the ground level in a state where the upper pallet 2 is at a predetermined lowered position. It has become.

A pair of left and right tiltable rail portions 2f and 2f are attached to correspond to a range portion in which the tire passes in the rear base frame portion 2k-2.
As can be seen by comparing FIG. 3 and FIG. 4, the retractable rail portions 2 f and 2 f can be raised to the front side, or can be substantially the same as the surface of the upper pallet 2. And can be pushed backwards. In the state of standing as shown in FIG. 4, the retractable rail portion 2f can be locked in this position so that it does not inadvertently fall down, and although not shown here, a locking mechanism for this purpose is also provided. Prepare. Then, as shown in FIG. 4, when the tiltable rail portion 2 f is raised and locked, the track placed on the upper pallet 2 falls from the rear as shown in FIGS. 1 (b) and 1 (c). It has a function as a stopper for preventing it.

In the side base frame portions 2a and 2a of the upper pallet 2 having the above-described structure, rotary shafts 2m and 2m are formed at predetermined dimension positions in the front-rear direction. And the bearing parts 4a and 4a provided in the vicinity of the upper end of the tiltable support column 4 are attached to the rotating shafts 2m and 2m on both the left and right sides.
Thereby, as for the relationship between the upright collapsible support column 4 and the upper pallet 2, the upper support pallet 2 is capable of seesaw operation with the rotating shaft 2 m (bearing portions 4 a, 4 a) as a fulcrum. It means that it is supported by.
The rotating shaft 2m here corresponds to the rotating shaft rx1 in FIG.

  Further, one end of the connecting arm 11 is attached to the rotating shaft 2m (bearing portions 4a and 4a) so as to be rotatable about the rotating shaft 2m. The other end of the connecting arm 11 is rotatably attached with the mounting position of the slide member 8 as a rotation axis.

  Further, the end of the hydraulic cylinder 10 on the cylinder body 10a side is rotatably attached with the mounting position of the slide member 8 as the rotation axis. The end portion of the rod 10b of the hydraulic cylinder 10 is attached to be rotatable about the attachment position of the rod receiving member 2e attached to the side portion of the upper pallet 2 as a rotation axis.

  An oil tank 9 is attached to the upper portion of the hydraulic cylinder 10, and oil filled in the oil tank 9 is supplied to an oil chamber on the hydraulic cylinder 10 side. The hydraulic cylinder 10 is provided for the purpose of buffering the force generated when the upper pallet 2 moves up and down, so that the lifting operation becomes slow, and this operation will be described later. .

In addition, receiving posts 14 and 14 having predetermined heights are attached to the front end sides of the base frames 3a and 3a on the side of the base portion 3 in an upright state, respectively. On the other hand, on the left and right sides of the upper pallet 2, stoppers 2d and 2d are attached at positions corresponding to the upper end positions of the receiving columns 14 and 14 along the front-rear direction. This part is shown in an enlarged manner in FIG.
As shown in FIGS. 4 and 11, when the upper pallet 2 is moved so that the front end direction is inclined downward, the stoppers 2d, 2d abuts from above. As a result, the position of the upper pallet 2 is regulated so that the front end direction does not tilt downward any further. That is, by setting the position at which the support columns 14 and 14 and the stoppers 2d and 2d abut, it is possible to set the angle of the upper pallet 2 with respect to the horizontal plane as the specified ascending position state. .

  Further, a ladder 19 is attached to the base frame 3 a on one side of the base portion 3 at a position slightly behind the receiving column 14. The ladder 19 is provided so that a driver who operates the truck 100 placed on the upper pallet 2 can get off the upper pallet 2.

Here, the example of the size of the main part about the three-dimensional parking apparatus 1 which has an above-described structure is described. In addition, the size shown here is that the truck to be parked in the upper / lower stage in FIG. It is assumed that the height is 1100 mm.
In this case, the upper pallet 2 is set to have a total length of 6000 mm (the tiltable rail portion 2f is in a standing state). The width is about 3000 mm. The size of the base part 3 itself is almost the same. However, the total length of the base portion 3 is a size obtained by omitting the ground tire rail 13.
In addition, the rotation axis rx1 serving as a fulcrum of the upper pallet 2 in the retractable support column 4 has a height of 1335 mm from the ground level. Then, in the state where the upper pallet 2 is at the specified lowering position as shown in FIG. 3, the angle formed by the upper pallet 2 and the ground level is set in a range of about 13 ° to 14 °.
In the state where the upper pallet 2 is regulated at the raised position shown in FIG. 4, the upper pallet 2 is inclined by a predetermined angle with respect to the horizontal, and the front end side is inclined downward. The inclination angle was set to 5 ° with respect to the horizontal plane. At this time, the height from the ground level at the rear end is approximately 1500 mm.

  The overall configuration of the three-dimensional parking apparatus 1 according to the present embodiment is as described above. Then, the structure of the site | part relevant to the raising / lowering operation | movement of the upper pallet 2 in the multi-story parking apparatus 1 by the said structure is demonstrated with reference to FIGS.

  Here, in the raising / lowering operation of the upper pallet 2, the force for raising / lowering the upper pallet 2 is buffered by the hydraulic cylinder 10 provided with the oil tank 9. First, the structure of the hydraulic cylinder 10 according to the embodiment will be described with reference to FIG.

FIG. 12 schematically shows the structure of the hydraulic cylinder 10 together with the oil tank 9.
First, the hydraulic cylinder 10 stores the piston 10c in a slidable manner within the cylinder body 10a. The end of the rod 10b is fixedly attached to one surface of the piston 10c, and the other end of the rod 10b projects from the cylinder body 10a.
In such a structure, the length of the rod 10b protruding from the cylinder body 10a changes as the piston 10c slides in the cylinder body 10a in a piston motion.
Further, since the piston 10c is provided in the cylinder body 10a, the inner chamber of the cylinder body 10a is formed such that the rod-side oil chamber 10d and the piston-side oil chamber 10e are separated by the piston 10c. . The rod-side oil chamber 10d and the piston-side oil chamber 10e are sealed by a piston 10c, and are directly between the rod-side oil chamber 10d and the piston-side oil chamber 10e (via the oil tank 9). There is no oil inflow or outflow.

The oil tank 9 is filled with oil. Two independent oil passages 25 and 26 are connected to the oil tank 9 in this case. The oil tank 9 is one oil chamber, and the oil passages 25 and 26 are connected to the same oil chamber of the oil tank 9. The oil passage 25 is connected to the piston-side oil chamber 10e, and the oil passage 26 is connected to the rod-side oil chamber 10a.
The oil passage 25 is provided with a flow rate adjustment valve 27, and the oil passage 26 is provided with a flow rate adjustment valve 28. The flow rate of the oil flowing through the oil passage 25 can be adjusted by operating the flow rate adjustment valve 27, and the flow rate of the oil flowing through the oil passage 26 can be adjusted by operating the flow rate adjustment valve 28.

  And as an external appearance structure of the hydraulic cylinder 10 by the said structure, it is shown by each side view of FIGS. In other words, the hydraulic cylinder 10 includes a rod 10b protruding from the cylinder body 10a with the cylinder body 10a as a main body. The protrusion length of the rod 10a varies in a state where the rod 10a is taken in and out of the cylinder body 10a according to the movement of the internal piston 10c.

In the case of the present embodiment, the oil tank 9 for supplying oil into the cylinder body 10a is fixedly attached to the upper part of the cylinder body 10a, so that it is integrated with the hydraulic cylinder 10 body. Yes.
Oil passage pipes 9a and 9b are provided between the oil tank 9 and the cylinder body 10a, and the oil in the inner chamber of the cylinder body 10a and the oil in the oil tank 9 are provided by these oil passage pipes 9a and 9b. Have been able to come and go.
Note that the hydraulic cylinder 10 and the oil tank 9 do not necessarily have to be integrated as long as they are connected by the oil passage pipes 9a and 9b as described above when viewed from the functional viewpoint. However, the present embodiment has an integrated structure for at least the following reasons.
First, it is preferable that the oil passage between the hydraulic cylinder 10 and the oil tank 9 be ideally connected directly. Therefore, in reality, the physical passage of the oil passage pipes 9a and 9b is preferable. The length is preferably as short as possible. The shorter the oil path, the smaller the amount of oil actually required, but the smaller the amount of oil, the more advantageous in terms of cost. In addition, as the amount of oil increases, inconveniences such as air becoming more likely to enter the oil chamber and appropriate pressure transmission are likely to occur. In the present embodiment, when the hydraulic cylinder 10 and the oil tank 9 are not integrated, the physical lengths of the oil passage pipes 9a and 9b become correspondingly long, so that the above-described inconvenience can be easily caused. Increases nature.
Further, as described below, the hydraulic cylinder 10 portion of the present embodiment moves around the rotating shaft 10f as a fulcrum according to the lifting / lowering operation of the upper pallet 2 shown in FIGS. Further, the upper pallet 2 shown in FIG. 3 may be changed between a state where the upper pallet 2 is in the lowered position and a storage state shown in FIG. 5, but depending on this time, the rotary pallet 10f is moved as a fulcrum. At the same time, it moves forward / backward along the guide rail 7.
In the case where the hydraulic cylinder 10 and the oil tank 9 are separated, considering that the movement of the hydraulic cylinder 10 is performed as described above, a corresponding oil passage pipe 9a, A physical length of 9b is required. Furthermore, considering the site where the multi-story parking device 1 is installed, for example, the movement of the hydraulic cylinder 10 is performed so that the remainder of the oil passage pipes 9a and 9b does not protrude beyond the outside of the multi-story parking device 1 more than necessary. Accordingly, there is a disadvantage that an apparatus part that winds and stores the oil passage pipes 9a and 9b is also required.
Therefore, if the hydraulic cylinder 10 and the oil tank 9 are integrated as in the present embodiment, the above problem does not occur. Further, the integration is advantageous in terms of component management and the like, and it is not necessary to consider the installation place for the oil tank 9, so that space saving can be promoted.

In this case, for example, the oil passage pipe 9 a corresponds to the oil passage 25 shown in FIG. 12 and connects the piston-side oil chamber 10 e and the oil tank 9. Further, the oil passage pipe 9 b corresponds to the oil passage 26 shown in FIG. 12 and connects the rod side oil chamber 10 d and the oil tank 9.
The oil passage pipes 9a and 9b are provided with flow rate adjusting knobs 9c and 9d, respectively. When the flow rate adjusting knobs 9c and 9d are tightened, the valves in the oil passage pipes 9a and 9b are made narrower, and the flow rate of the oil flowing through the oil passage pipes 9a and 9b is reduced. On the contrary, if the flow rate adjusting knobs 9c and 9d are loosened, the valves in the oil passage pipes 9a and 9b become wider and the flow rate of the oil flowing through the oil passage pipes 9a and 9b is increased. The flow rate adjusting knobs 9c and 9d correspond to the flow rate adjusting valves 27 and 28, respectively, in FIG.

Considering that the hydraulic cylinder 10 has the above-described structure, the up and down operation of the upper pallet 2 will be described.
First, FIG. 8 shows a state in which the upper pallet 2 is in the lowered position as a side view of the peripheral part to the retractable support column 4 and the hydraulic cylinder 10 in the multi-story parking apparatus 1. As can be understood from the above description, this state is obtained when the vehicle is not parked on the upper pallet 2, that is, when the truck 100 is not placed in the specified position range of the upper pallet 2 (the truck 100 is completely not in the upper pallet). 2 is also included).
The upper pallet 2 is supported so that the seesaw operation is possible with the rotation shaft 2m (rx1) as a fulcrum, but as described above with reference to FIG. Is not placed, the center of gravity is on the rear side with respect to the rotating shaft 2m as a fulcrum. For this reason, a state in which the rear end side of the upper pallet 2 is inclined downward is in a state shown in FIG.

  In the state shown in FIG. 8, the rod 10 b of the hydraulic cylinder 10 is in a state where it enters the cylinder body 10 a most within the movable range accompanying the raising and lowering operation of the upper pallet 2. In other words, the length protruding from the cylinder body 10a is the shortest.

  From this state, it is assumed that the truck 100 is advanced from the rear side of the upper pallet 2 to enter the upper pallet 2 as shown in FIG. As the truck 100 enters, the center of gravity of the upper pallet 2 moves in the forward direction. However, if the truck 100 has traveled to a specified position range, the rotating shaft 2m as a fulcrum The center of gravity moves in the forward direction. Then, the upper pallet 2 has a force so as to start a seesaw motion with the rotary shaft 2m as a fulcrum, with the front end portion facing downward and the rear end portion facing upward.

  Depending on the movement of the upper pallet 2, as shown by an arrow a in FIG. 9, the rotation shaft 10 f of the slide member 8 serves as a fulcrum (this fulcrum (10 f) In this case, it is located at a fixed position without moving along the slide rail 7), and a force for lifting the hydraulic cylinder 10 works with the portion of the rotary shaft 2 e-1 of the rod receiving member 2 e of the upper pallet 2 as an action point. It will be. At the same time, a force for pulling the rod 10b acts on the portion of the rotating shaft 2e-1 of the rod receiving member 2e as shown by the arrow b.

The rod 10b is pulled out from the cylinder body 10a by the force pulling the rod 10b. That is, the rod 10b generates a force in the direction of going out from the cylinder body 10a. However, since the hydraulic cylinder 10 has the structure shown in FIG. As it is pulled out from the body 10a, the piston 10c moves toward the rod side oil chamber 10d. As a result, the volume of the rod side oil chamber 10d is reduced, so that the oil filled in the rod side oil chamber 10d flows to the oil tank 9 via the oil passage 26. At the same time, since the volume of the piston-side oil chamber 10e increases, the oil flows into the piston-side oil chamber 10e from the oil tank 9 via the oil passage 25.
Then, when such an oil flow is generated, the rod 10b is pulled and moved so as to lift the rear end side of the upper pallet 2, that is, the force that the rod 10b tries to go out from the cylinder body 10a. Is buffered and weakened by the hydraulic cylinder 10.

Even after this, the upper pallet 2 moves with the rear end side being further lifted from the state shown in FIG. At this time as well, the above-described operation of the hydraulic cylinder 10 is in progress, and during this time as well, the moving force is weakened by lifting the rear end side of the upper pallet 2.
Finally, as shown in FIG. 10, the rear end side of the upper pallet 2 is pulled up to a specified ascending position. At this time, as shown in FIG. 11, the stopper 2d attached to the upper pallet 2 exerts a force almost directly below as shown by the direction of the arrow F with respect to the upper end portion of the receiving column 14. In this way, the position is restricted at the specified ascending position.

  For example, when the hydraulic cylinder 10 is not provided, the force for moving the rear end side of the upper pallet 2 by lifting is not weakened, so that the upper pallet 2 moves at a higher speed as the center of gravity moves forward. It will move. For this reason, as shown in FIG. 10, at the moment when the position is reached and the position is regulated, a very large inertia force works and a large impact is generated. On the other hand, by providing the hydraulic cylinder 10 that operates as described above, the force for moving the upper pallet 2 is weakened, and the moving speed can be made gentle. As shown in FIG. 11, even when the stopper 2 d comes into contact with the receiving column 14 and the upper pallet 2 reaches the specified position, the inertial force at that time is very small. There will be no impact.

In addition, in the state where the upper pallet 2 is at the specified ascending position as shown in FIG. 10, the track 100 placed on the upper pallet 2 is within the specified range (that is, forward of the rotating shaft 2m). It is assumed that the center of gravity is located, and the front pallet 2 is moving forward to a state in which a force for inclining the front end side of the upper pallet 2 is applied. When the truck 100 is lowered from the upper pallet 2, as described above, the track 100 is positioned outside the specified range on the upper pallet 2 (that is, the center of gravity is located behind the rotating shaft 2 m, The rear end of the upper pallet 2 is moved backward until it is in a state in which a force for inclining downward is applied.
As a result, the upper pallet 2 moves so that the rear end side faces downward with the rotating shaft 2m as a fulcrum while the track 100 is placed. From the state shown in FIG. 10, the state shown in FIG. After passing through the state, the operation is finally stopped until it reaches a predetermined lowered position shown in FIG.

  When the upper pallet 2 is lowered as described above, a force in the direction opposite to that when the upper pallet 2 is raised acts on the hydraulic cylinder 10. That is, the force (lower arrow a) is used to pull down the hydraulic cylinder 10 with the rotary shaft 10f of the slide member 8 as a fulcrum and the rotary shaft 2e-1 portion of the rod receiving member 2e of the upper pallet 2 as the operating point. At the same time, a force that pushes the rod 10b into the cylinder body 10a side (a force in the direction opposite to the arrow b) acts at the portion of the rotating shaft 2e-1 of the rod receiving member 2e. It will be.

  The rod 10b enters the cylinder body 10a by the force to push the rod 10b, and the piston 10c moves in the direction of the piston-side oil chamber 10e according to this operation. Thereby, since the volume of the piston side oil chamber 10e becomes small, the oil with which the piston side oil chamber 10e is filled flows into the oil tank 9 via the oil path 25. At the same time, the volume of the rod-side oil chamber 10d increases, and oil flows into the rod-side oil chamber 10d from the oil tank 9 via the oil passage 25. And by such a flow of oil, the force (force which pushes the rod 10b) which makes the rear end side of the upper pallet 2 face downward is buffered.

From the description so far, in the present embodiment, the upper pallet 2 supported so as to be able to operate the seesaw is moved by the center of gravity using the own weight of the upper pallet 2 itself and the weight of the truck 100 placed thereon, so that the upper pallet It is understood that 2 can be moved up and down.
Further, by operating the hydraulic cylinder 10 as described above, it is possible to prevent the occurrence of an impact as a gentle movement in both the rising and lowering operations of the upper pallet 2. .

For example, a configuration in which a hydraulic cylinder is provided in a mechanism for raising and lowering a heavy object such as the upper pallet 2 has been known so far.
In such a conventional configuration, a hydraulic pump is generally provided, and the oil supply to the oil chamber of the hydraulic cylinder is controlled by the hydraulic pump. In such a configuration, the rod of the hydraulic cylinder is controlled to extend according to the oil supply control of the hydraulic pump. The heavy object is moved up and down by the force for extending the rod. With regard to the lifting and lowering operation of the heavy object in this case, the movement speed during the lifting and lowering can be made moderate by controlling the oil supply pressure by the hydraulic pump and the like so that no shock is generated.

However, it can be said that such a conventional configuration gives a force to push out or push back by a rod by driving a hydraulic cylinder, thereby lifting and lowering a heavy object. That is, the hydraulic cylinder functions as a part that directly applies a force for lifting to the lift.
On the other hand, the hydraulic cylinder 10 provided in the multi-story parking apparatus 1 of the present embodiment has a role of buffering the force received on the rod by the structure shown in FIG. 12, and is rather a shock absorber. It performs a typical function.

  And in the conventional structure, it is normal to perform the oil supply operation | movement by a hydraulic pump using electric power. On the other hand, according to the present embodiment, the lifting of the upper pallet 2 which is a heavy object is obtained as a seesaw motion according to the center of gravity movement due to the own weight of the upper pallet 2 itself and the weight of the placing object (track). In addition, as a means for reducing the shock, the oil amount between the piston-side oil chamber 10e and the rod-side oil chamber 10d is increased or decreased depending on the force applied to the rod 10b of the hydraulic cylinder 10. It is based on a simple structure that only flows out. With this configuration, according to the present embodiment, it is possible to obtain a gentle lifting / lowering operation of the heavy object (upper pallet 2) without driving the hydraulic cylinder 10 by the hydraulic pump. That is, while the lifting mechanism of the heavy object (upper pallet 2) is provided with a hydraulic cylinder, the structure does not require electric power for the reciprocating operation for raising and lowering the heavy object.

Further, as described above with reference to FIG. 1, the three-dimensional parking apparatus 1 of the present embodiment is stored in a flat state so that the upper pallet 2 is overlapped with the base portion 3 by tilting the tiltable column 4 in an upright state. In this housed state, the truck 100 can be passed over the multi-story parking device 1. On the contrary, it is also possible to return to the parking enabled state in which the upper pallet 2 can perform seesaw motion (the upper pallet 2 is in the lowered position) by raising the tiltable support column 4 in the flat state and making it stand upright. .
Then, suppose that the mechanism for changing the state of the multi-story parking apparatus 1 between a parking possible state and a storage state is demonstrated.

Here, as an order, the case where the retractable support column 4 is caused from the stored state to enter the parking enabled state will be described as an example.
The side view of FIG. 13 shows the storage state. As shown in this figure, in a state where the retractable support column 4 is in the retracted state and is tilted sideways (horizontal), the retractable support column 4 is placed sideways on the base frame 3 a of the base portion 3. It will be in such a state. Since the upper pallet 2 is supported by the rotating shaft 2m, in the position state of the rotating shaft 2m shown in FIG. It is understood that it is obtained.

At this time, the connecting arm 11 that connects the rotating shaft 2m and the slide member 8 is also in a horizontal state, so that the slide member 8 is located at the rearmost position in the movable range of the guide rail 7. Yes. In addition, in this FIG. 13 and the side view of FIG. 14, FIG. 15 mentioned later, the top view and front view regarding the part of the guide rail 7 are shown.
As can be seen from the plan view and the front view of the guide rail 7, the guide rail 7 has a substantially concave cross section so that a rail groove 7a is formed along the front-rear direction. On the other hand, the slide member 8 is attached to be slidable. A rotary shaft 10f on the cylinder body 10a side of the hydraulic cylinder 10 is attached to the rotary shaft hole 8a of the slide member 8, and an end portion of the connecting arm 11 is also rotatably attached to the rotary shaft 10f.

As described above, the rotary shaft 10 f on the cylinder body 10 a side of the hydraulic cylinder 10 is further attached to the slide member 8. The tip of the rod 10b of the hydraulic cylinder 10 is attached to the rotary shaft 2e-1 located on the rear end side of the upper pallet 2. In this way, the hydraulic cylinder 10 supported between the rotating shaft 10f and the rotating shaft 2e-1 is also substantially horizontal.
In other words, when the retractable support column 4 is in the horizontal state as the storage state, the connecting arm 11 and the hydraulic cylinder 10 are also in a state of being positioned horizontally so as to be substantially in line with the retractable support column 4. . Further, in this state, the rod 10b of the hydraulic cylinder 10 is in the stowed state shown in FIG. 13 and in a parkable state in which the tiltable column 4 shown in FIG. 15 described later is upright (the upper pallet 2 is in the lowered position). In the movable range accompanying the movement between the cylinder body 10a and the cylinder body 10a.

Here, in the guard column 6, a chain block 30 is provided at a position on the upper end side thereof.
The suspension chain 20 is pulled out from the chain block 30, and the end of the suspension chain 20 is fixed to the tiltable column 4. That is, in the tiltable support column 4, the suspension chain support portion 4b is provided on the surface facing upward in the position state shown in FIG. It is fixed in such a way. A structure for winding / unwinding the suspension chain 20 by the chain block 30 will be described later.

From the state shown in FIG. 13, it is assumed that, for example, the suspension chain 20 is wound up by the chain block 30 to be pulled in the direction indicated by the arrow c. Then, as shown in FIG. 14, the tiltable support column 4 connected to the suspension chain 20 is raised with the rotation shaft 5b as a base point.
As the retractable support column 4 is raised in this way, the position of the rotary shaft 2m on the upper end side of the retractable support column 4 becomes higher while moving along the locus indicated by the arrow d. Accordingly, the upper pallet 2 moves forward (moving so that the angle formed by the ground and the surface of the rear end side of the upper pallet 2 increases) while proceeding forward, the front end side facing upward. Will do.
At this time, the connecting arm 11 moves so that the connecting portion with the rotating shaft 2m follows the locus indicated by the arrow d. As a result, the connecting arm 11 is pulled as if the slide member 8 connected by the rotary shaft 10f is slid forward as indicated by an arrow e. Then, when the slide member 8 is slid forward by the movement of the connecting arm 11, a force for pulling the hydraulic cylinder 10 having the end attached to the slide member 8 in the forward direction acts. Thus, the tiltable column 4 can be easily raised.
Further, as the upper pallet 2 moves as described above, the part of the rotating shaft 2e-1 in the vicinity of the rear end portion of the upper pallet 2 is also raised along the locus indicated by the arrow f. As a result, the hydraulic cylinder 10 in the horizontal state is also lifted as indicated by the arrow g with the rotary shaft 10f as a fulcrum, and the angle between the direction along the rod central axis of the hydraulic cylinder 10 and the horizontal plane is increased. Arise.

Further, by further winding the suspension chain 20, finally, as shown in FIG. 15, the tiltable column 4 can be in an upright state. This state is a state in which parking is possible in a state where the upper pallet 2 is present at a predetermined lowered position. That is, it is in the same position state as shown in FIG.
At this time, the slide member 8 is in the most forward position in the movable range along the guide rail 7. Further, the rotating shaft 2e-1 in the vicinity of the rear end portion of the upper pallet 2 is also located at a predetermined height according to the upper pallet 2 being at a predetermined lowered position. However, a predetermined angle is obtained with respect to the horizontal plane accordingly. In addition, when it changes to the state shown in FIG. 15 through FIG. 13 from FIG. 14, according to the motion of the upper stage pallet 2, the length of the rotating shaft 2e-1 will change from the rotating shaft 10f. However, in response to this, the protruding length of the rod 10b of the hydraulic cylinder 10 changes.

Further, when returning from the parking possible state shown in FIG. 15 to the storage state shown in FIG. 13, the suspension chain 20 is unwound and loosened by the chain block 30. As the suspension chain 20 is loosened in this manner, the collapsible column 4 falls from the state shown in FIG. 13 to the rear side due to its own weight and the weight of the upper pallet 2 as shown in FIG. Will be able to. In this manner, the upper pallet 2 moves in the reverse direction to the case where the tiltable column 4 is raised, that is, moves slightly backward, It moves by the movement of getting closer to the horizontal as the angle becomes smaller.
At this time, the connecting arm 11 is lowered while moving along a trajectory in the direction opposite to the arrow d. Depending on the movement of the connecting arm 11, the slide member 8 is slid rearward, whereby a force is applied by pushing the hydraulic cylinder 10 whose end is attached to the slide member 8 to the rear side. It will be.
Then, when the tiltable support column 4 is tilted until it becomes horizontal, the upper pallet 2 returns to the state of being stacked on the base portion 3 as shown in FIG.

Next, a mechanism for winding / unwinding the suspension chain 20 will be described.
FIGS. 16A, 16B, and 16C are a plan view, a front view, and a side view, respectively, showing a part related to winding / unwinding of the suspension chain 20 in the multi-story parking apparatus 1. FIG. Regarding FIG. 16A, the downward direction on the paper is the front side of the multi-story parking device 1, and the upward direction is the rear side of the multi-story parking device 1. 16C, the left direction is the front side of the multi-story parking device 1 and the right direction is the rear side of the multi-story parking device 1 in the drawing.
As shown in FIG. 6, the guard column 6 is provided for each of the left and right base frame portions 3 a and 3 a in the base portion 3, and is a pair of left and right. In FIGS. 16 (a) and 16 (b), these left and right guard columns are labeled 6A and 6B on the left side and the right side as viewed from the front.
And as shown to 16 (a) (b) (c), the chain block 30 is attached to each upper side in the guard support | pillar 6A, 6B. The part of this chain block 30 is enlarged from the front (plane) and shown in FIG.

For example, the chain block 30 includes a gear box 41 on the right side in the drawing. The gear box 41 is stored with a combination of parts including various gears necessary for obtaining movement as a chain block.
A winding gear 42 is attached to the left side of the gear box 41. As can be seen from the suspension chain 20 being wound around the winding gear 41, the suspension chain 20 is for winding / unwinding according to the direction of rotation.
The winding gear 42 rotates according to a predetermined rotation ratio in accordance with the rotation of the handwheel 43 described later. In this case, when viewed from the side facing the gear box 41 side, the suspension chain 20 is wound up when the winding gear 42 rotates counterclockwise, and the suspension chain 20 is unwound when rotated in the clockwise direction. It has become.

  A hand wheel 43 is attached to the left side of the winding gear 41. In the case of an ordinary chain block, a hand-wound chain is wound around the handwheel 43, and the handwheel 43 is rotated clockwise / counterclockwise by pulling the hand-wound chain. As described above, according to the rotation of the handwheel 43, the winding gear 41 rotates at a predetermined rotation ratio, and the load is lifted by winding the suspension chain 20 and the load is unloaded by unwinding. To be done.

However, in the present embodiment, as can be seen from the fact that nothing is wound around the handwheel 43 shown in FIG. 17, the manually wound chain is removed. In order to rotate the handwheel 43 in the present embodiment, the speed reducer 31 is used instead of the hand-wound chain as will be described later.
The handwheel 43 is fixedly attached to the connecting shaft 32. That is, the handwheel 43 in this case is configured to rotate according to the rotation of the connecting shaft 32.
Similarly, the sprocket 35 is fixedly attached to the connecting shaft 32 together with the handwheel 43.
Accordingly, when the connecting shaft 32 is rotated, the handwheel 43 and the sprocket 43 rotate in synchronization with the rotation.
A sprocket chain 37 is wound around the sprocket 35 so as to mesh with the sprocket 35.

Returning to FIG.
The connecting shaft 32 of the chain block 30 on the guard column 6A side is also an output shaft of the speed reducer 31 and is also connected to the speed reducer 31. That is, when the output shaft of the speed reducer 31 rotates, the connecting shaft 32 rotates. Hereinafter, the shaft denoted by reference numeral 32 is referred to as a connecting shaft (output shaft) 32 or an output shaft (connecting shaft) 32.

  As shown in FIGS. 16 (a) and 16 (b), the speed reducer 31 in this case employs an input shaft 31a and an output shaft (connection shaft) 32 that are orthogonal to each other by 90 °. . The reason for this will be described later.

  A sprocket 37 is attached to the lower side of the guard column 6A so as to be rotatable about the transmission rotation shaft 38 as a rotation shaft. The sprocket 37 is connected to the sprocket 35 attached to the chain block 30 by a sprocket chain 36 in the guard column 6A. Thus, that is, the rotation of the sprocket 35 is transmitted to the sprocket 37 by the sprocket chain 36, and the sprocket 35 and the sprocket 37 are rotated in synchronization.

In the right guard column 6B, the chain block 30 to which the sprocket 35 is attached and the sprocket 37 to be attached to the transmission rotating shaft 38 are provided by the same structure as the guard column 6A. Since the speed reducer 31 is not attached on the guard column 6B side, the connecting shaft 32 is used as an output shaft and is not connected to the speed reducer 31.
For example, the length of the connecting shaft 32 shown in this figure is that of the connecting shaft 32 on the guard column 6A side connected to the speed reducer 31. That is, in order to connect with the reduction gear 31, the length which extended the part is required. On the other hand, since the connecting shaft 32 of the guard column 6B is not connected to the speed reducer 31 as described above, the length of the connecting shaft 32 may be, for example, up to the position indicated by the alternate long and short dash line in FIG. Incidentally, the original length of the connecting shaft 32 in the component as the chain block 30 corresponds to the connecting shaft 32 on the guard column 6B side (that is, up to the vicinity of the two-dot chain line in FIG. 17). Actually, in the chain block 30 of the guard column 6A, for example, the length shown in FIG. 17 is obtained by exchanging with the connecting shaft 32 having a different length.
Further, the end portion of the suspension chain 20 wound around the winding gear 41 of the chain block 30 on the guard column 6A side is attached to the tiltable column 4 on the left side when viewed from the front of the multi-story parking device 1. Further, the end of the suspension chain 20 wound around the winding gear 41 of the chain block 30 on the guard column 6B side is attached to the tiltable column 4 on the right side when viewed from the front of the multi-story parking device 1.

For example, the three-dimensional parking apparatus 1 is changed from a storage state (a state shown in FIG. 13) in which a truck can pass to a parking ready state (a state shown in FIG. 15) that is caused to stand upright by raising the tiltable column 4. Sometimes, for example, an operator performs an operation of rotating the input shaft 31a of the speed reducer 31 in a predetermined direction. In this case, for example, the input shaft 31a shown in FIG. 16B is rotated clockwise.
The input shaft 31a has a regular hexagonal cross section. In order to rotate the input shaft 31a, a tool such as a crank to which a wrench suitable for the regular hexagonal size of the cross section of the input shaft 31a is attached may be used. It is also conceivable to use a power tool called a so-called impact driver to which a wrench suitable for the regular hexagonal size of the cross section of the input shaft 31a is attached.

  Here, the impact driver itself is an electric tool and is driven using electric power. However, as will be described later, in the process of causing the tiltable support column 4 according to the rotation of the input shaft 31a, and in the process of tilting, the multi-story parking apparatus 1 itself uses no power at all. The input shaft 31a can be rotated not only by the electric tool but also by a manual tool such as a crank as described above. As can be seen from this, it should be noted that no electric power is required to move the movable part of the multi-story parking apparatus 1 of the present embodiment.

As a result, the output shaft (connection shaft) 32 of the speed reducer 31 is rotated counterclockwise when viewed from the direction of FIG. 16C according to the rotation ratio with the input shaft 31a. As described above, since the handwheel 43 and the sprocket 35 are fixedly attached to the output shaft (connection shaft) 32, the handwheel 43 and the sprocket 35 are configured in the same manner as the output shaft (connection shaft) 32. Will rotate.
In other words, rotating the input shaft 31a of the speed reducer 31 means rotating the hand wheel 43, and in the case of the normal chain block 30, it is equivalent to pulling the hand chain and rotating the hand wheel itself. .

Here, if the sprocket 35 of the chain block 30 on the guard column 6A side to which the speed reducer 31 is attached rotates as described above, this rotation is transmitted to the sprocket 37 by the sprocket chain 36. The sprocket 37 is fixedly attached to the transmission rotating shaft 38 together with the sprocket 37 of the guard strut 6B on the opposite side. Further, on the guard column 6B side, the rotation of the sprocket 37 is attached to the sprocket 35 attached to the chain block 30 by the sprocket chain 36.
Thus, when the input shaft 31a of the speed reducer 31 on the guard column 6A side is rotated, this rotation operation is performed as follows: connecting shaft (output shaft) 32 → sprocket 35 (guard column 6A side) → sprocket chain 36 (guard column 36) 6A side) → sprocket 37 (guard strut 6A side) → transmission rotating shaft 38 → sprocket 37 (guard strut 6B side) → sprocket chain 36 (guard strut 6B side) → sprocket 35 (guard strut 6B side) It will follow.

  When the connecting shaft (output shaft) 32 of the speed reducer 31 rotates according to the rotation of the input shaft 31a, the handwheel also performs the same rotation operation in the chain block 30 on the guard column 6A side. become. As a result, the winding gear 42 of the chain block 30 on the guard column 6A side also rotates counterclockwise when viewed from the direction shown in FIG. It will follow.

Here, as described above, the rotation of the input shaft 31a of the speed reducer 31 on the guard column 6A side (the rotation of the sprocket 35 on the guard column 6A side) is transmitted to the sprocket 35 of the guard column 6B on the opposite side. It has come to be.
Therefore, the sprocket 35 on the guard column 6A side and the sprocket 35 of the guard column 6B are configured to perform the same rotational movement. As a result, the connecting shaft 32 of the chain block 30 on the guard column 6B side also performs the same rotational movement as the connecting shaft 32 on the guard column 6A side. That is, the connecting shafts 32 on the guard columns 6A and 6B side rotate in the same counterclockwise direction and at the same rotational speed. As a result, the winding gears 42 and 42 of the chain blocks 30 on the guard columns 6A and 6B side also perform the same rotational movement. Thereby, also on the guard column 6B side, the suspension chain 20 is wound up in a state synchronized with the guard column 6A side. Thereby, it becomes possible to pull up the tiltable support column 4 by winding up and down the same suspension chain 20 on the left and right.

Further, in order to bring down the tiltable support column 4 from the parking available state shown in FIG. 15 to the storage state shown in FIG. Rotate counterclockwise as viewed from the top. That is, it is rotated in the direction opposite to the case where the tiltable column 4 is caused. As a result, the output shaft (connection shaft) 32 also rotates in the clockwise direction as viewed from the direction of FIG. Further, the winding gear 42 of the chain block 30 on the guard column 6A side also rotates in the clockwise direction, and the suspension chain 20 is unwound.
As a result, the sprocket 35 of the chain block 30 on the guard column 6A side also rotates in the clockwise direction when viewed from the direction of FIG. The sprocket 35 of the chain block 30 on the guard column 6B side to which this rotation is transmitted also rotates clockwise as viewed from the direction of FIG. Then, by the rotation of the sprocket 35 on the guard column 6B side, the winding gear 42 of the chain block 30 on the same guard column 6A side also rotates clockwise to unwind the suspension chain 20. At this time, the unwinding of the suspension chain 20 on the guard column 6A side and the guard column 6B side is performed in synchronization.

Inverting the collapsible column 4 of the multi-story parking apparatus 1 of the present embodiment means that the upper pallet 2 supported by the collapsible column 4 is also lifted and lowered. Since the upper pallet 2 has a considerable weight, this requires a corresponding force.
For example, the chain block 30 may be provided on only one of the left and right sides, and the other tiltable support column 4 may be inverted when the tiltable support column 4 is caused to move by the one chain block 30. Conceivable. However, since a considerable force is required to invert the tiltable column 4 as described above, it is difficult to smoothly lift / fall the upper pallet 2 together with the tiltable column 4 with this configuration. Therefore, it is necessary to adopt a configuration for inverting the pair of tiltable columns 4 in synchronism with the same driving force.

Generally considered as such a configuration is to provide a motor for rotating the handwheel of the chain block for pulling up the tiltable column 4 by the same mechanism corresponding to each of the left and right chain blocks. The rotational driving of the pair of motors is started and stopped at the same timing. In this way, the movement of the tiltable column 4 can be synchronized with the same driving force. However, in this case, a part that is electrically driven as a three-dimensional parking apparatus is included.
Therefore, with the above-described configuration of the present embodiment, the driving and tuning by the same level of force for the movement of the tiltable support column 4 does not require electric power driving and is simplified. It can be realized reliably.

Also, as described above with reference to FIGS. 16 (a) and 16 (b), the reducer 31 employs an input shaft 31a and an output shaft (connection shaft) 32 that are orthogonal to each other by 90 °. Yes. Thus, if it is the relationship which becomes 90 degrees about the input shaft 31a and the output shaft (connection shaft) 32, the axial direction of the input shaft 31a will be as shown in FIG. It will be along the front-back direction.
Here, for example, it is assumed that the speed reducer 31 is one in which the axial directions of the input shaft 31a and the output shaft (connection shaft) 32 are coincident or parallel. The worker who rotates the input shaft 31a works while being positioned on the front side of the input shaft 31a. The position of the worker 80 in this case is as shown in the plan view of FIG. Furthermore, it becomes further outside on the front left side of the multi-story parking device 1. In the case of this position, it is necessary to secure a width W for enabling an operator to perform work on the left side of the front of the multi-story parking apparatus 1. Here, for example, in the case shown in FIG. 18A, when as many parking devices 1 as possible are arranged in a motor pool as shown in FIG. 2, between the three-dimensional parking devices 1 adjacent to each other on the left and right. In order to correspond to the width W, it is necessary to arrange them with a gap that allows the operator to work. For this reason, the number of installations of the three-dimensional parking apparatus 1 per unit area may decrease.

  On the other hand, in the case of the present embodiment, as shown in FIG. 18 (b), the worker 80 is located immediately along the front-rear direction of the multi-story parking apparatus 1. . In this case, as in the case of FIG. 18A, it is not necessary to secure a corresponding width with respect to the outer side of the multi-story parking apparatus 1. And when it is going to arrange | position the multi-story parking apparatus 1 side by side, the space between the right and left of the multi-story parking apparatus 1 can be made narrower than the case shown to Fig.18 (a). That is, the number of three-dimensional parking devices 1 installed per unit area can be increased, and the number of parkable trucks can be increased accordingly.

Moreover, in this Embodiment, when raising the fallable support | pillar 4 from the accommodation state shown in FIG.
FIG. 19 shows a state in which the retractable support column 4 is tilted horizontally. This state is the same as the state shown in FIG. 13, but in this drawing, in particular, the pulling biasing mechanism of the tiltable column 4 using a spring is shown.
In this figure, the spring box 16 attached to the side part of the base frame 3a on the side of the base part 3 is shown. A spring 45 is stored in the spring box 16. One end of the spring 45 is fixedly attached to the inner wall of the spring box 16 on the rear end portion side on the rear end portion side (right side in the drawing). The other end is connected to one end of the wire 46. The wire 46 connected to the end of the spring 45 is extended in the horizontal direction as it is and wound around the guide washer 47 on the lower side of the guard column 6, where the direction is changed by 90 ° and extended vertically upward. Is done. The wire 46 is further extended in a direction changed by a guide washer 48 provided on the upper side of the guard column 6 as shown in the figure, and an end portion of the wire 46 is provided on the outer side surface of the tiltable column 4. In 4c, for example, a connection is made and the like is fixed. For confirmation, the wire 46 has a predetermined fixed length made of, for example, iron, and is not extensible.

The spring 45 and the tiltable support column 4 are connected via the wire 46 as described above. However, when the tiltable support column 4 is tilted as shown in FIG. In the direction indicated by the arrow H, the spring 45 is extended by a predetermined length.
When this state is viewed from the side of the collapsible support column 4 positioned horizontally, as indicated by an arrow G, a force is applied in a direction to be caused by the wire 46 (that is, the spring 45). Become. However, the force itself shown by the arrow G here is not large enough to cause the tiltable column 4. Therefore, even if the force indicated by the arrow G is applied, the tiltable column 4 is not caused and maintains the state shown in FIG.

As described above with reference to FIG. 16, when the folding gear 42 of the chain block 30 is rotated in the winding direction to cause the folding column 4 to move, first, the folding column 4 that has fallen horizontally is moved. When first triggered, it requires a great deal of power.
In the present embodiment, at this time, as shown in FIG. 19, a force in a direction to cause the tiltable column 4 to act as indicated by an arrow G by the tension of the spring 45 has already been applied. For this reason, when the suspension chain is wound up by the winding gear 42, the force due to the tension of the spring 45 is supplementarily added to the force to cause the tiltable support column 4, and the tiltable support column 4 may be caused. It has been done smoothly.

In addition, as shown in FIG. 20, the spring 45 is shortened and its tension is gradually weakened as the retractable support column 4 approaches an upright state from the state shown in FIG. Become. For example, while the force gradually weakens, while the spring 45 is being pulled, the force that pulls the tiltable column 4 toward the guard column 6 as shown by the arrow G is working. The tiltable column 4 can be raised with less force.
In the state where the retractable support column 4 is upright, the state of the spring 45 has returned to the level where almost no tension is generated, and the force in the direction indicated by the arrow G is hardly generated. In this way, when the tiltable support column 4 starts to fall again from an upright state, it is possible to use a force opposite to the direction in which the tiltable support column 4 is tilted (that is, a force indicated by an arrow G). The smooth movement of the falling column 4 is not hindered.

  Furthermore, in order to obtain a smooth movement when the tiltable column 4 starts to fall from the upright state, an urging unit 50 is provided as shown in FIG. As shown in the figure, the urging unit 50 is provided at a position on the upper surface of the guard column 6 so as to substantially face the front side surface of the tiltable column 4 when the tiltable column 4 stands upright. It is done.

As a structure of the urging unit 50, for example, as shown in FIG. 22A, a slide member 52, a push pin member 53, and a spring 54 are provided in the main body cover portion 51.
The slide member 52 is provided so as to be slidable along the inner wall side surface of the main body cover portion 51. The push pin member 53 is attached so as to be integrated with the slide member 52, and the length protruding from the opening 51 a of the main body cover portion 51 changes according to the slide movement of the slide member 52. It has become.
Further, the spring 54 is provided between the slide portion 52 and the inner wall of the back surface portion, which is supposed to be located on the left side of the paper surface, in the main body cover portion 51.

FIG. 22A shows a state in which the tiltable column 4 is assumed to be upright. In this state, the push pin member 53 is pushed into the left direction on the paper surface by the side surface of the tiltable support column 4. In this state, the spring 54 is in its most contracted state and a corresponding tension is generated. Depending on this tension, as indicated by the broken-line arrow in the figure, a force that pushes the slide member 52 to the right in the drawing is in a working state. That is, at this time, the tip surface portion of the push pin member 53 applies a force in a direction in which the tiltable support column 4 is tilted in a state of being in contact with the tiltable support column 4.
For example, when the suspension chain 20 is loosened by the chain block 30 in order to tilt the tiltable support column 4, the push pin described above is shown as a transition from FIG. 22 (a) to FIG. 22 (b), for example. The member 53 is energized by the force pushed out while coming into contact with the tiltable column 4, so that the tiltable column 4 can move from an upright position to a position where the column 53 falls.
For example, when the retractable support column 4 further falls from the state shown in FIG. 22B, the retractable support column 4 and the front end surface of the push pin member 53 are separated as shown in, for example, FIG. Thus, the pushing to the push pin member 53 by the tiltable support column 4 is released.
Such an urging unit 50 may be attached to the guard struts 6 (6A, 6B) on both the left and right sides. However, depending on the selection of the tension of the spring 54, etc. Even if it was attached only to the armature, it was possible to make a smooth transition from the upright state to the state where the tiltable column 4 was tilted obliquely.

Moreover, since the state in which the tiltable column 4 is upright is obtained by winding the suspension chain 20 of the chain block 30, the tiltable column 4 is not inadvertently collapsed from this state. However, in this embodiment, in order to make it safer, as shown in FIG. 23, the upright collapsible column 4 is prevented from falling.
That is, as shown in FIG. 23, pin through-holes 5a and 5a are formed in the support columns 5A and 5B. The pin through-holes 5a, 5a are located just outside the side surface of the upright tiltable column 4 when viewed from the side surface direction. Then, as shown in the figure, the fall prevention pins 60 are allowed to penetrate through the pin through holes 5a and 5a. As a result, even if the tiltable support column 4 is tilted in the direction in which it falls, the pin shaft portion of the fall prevention pin 60 restricts the movement of the tiltable support column 4 so that the tiltable support column 4 falls. It is prevented from falling down.

Further, as shown in FIG. 1C, when the lower track 100 enters, as shown in FIG. 7, the rear tire of the track 200 is at the rearmost side of the base portion 3. It will step over the connecting frame 3b. In this way, the situation in which the rear tire of the track 200 directly steps on the connecting frame 3b is not preferable because it damages the connecting frame 3b. Therefore, in practice, as shown as a side view on the lower side of the sheet of FIG. 7, a substantially chevron-shaped frame guard plate 22 is provided to cover the connecting frame 3b from above.
Incidentally, the connecting frame 3b located on the front side (the left side of the drawing) with respect to the connecting frame 3b provided with the frame guard plate 22 functions as a ring stopper for the rear tire of the truck 200.

Further, as shown in FIGS. 3 to 6, the front end portion of the upper pallet 2 is provided with a ring stop member 12, and the track 100 placed on the upper pallet 2 advances too far forward. There has been no such thing.
The ring stop member 12 can be easily attached / detached. As shown in FIG. 5 and the like, when the upper pallet 2 is stored and the truck is to be passed, it is possible to remove the ring stop member 12 so as not to obstruct the passage of the truck.

In addition, as the actual structure of the multi-story parking apparatus 1 according to the embodiment, it is not always necessary to provide all the mechanisms and structures described so far.
For example, the case where the multi-story parking apparatus 1 is installed as shown in FIG. 2A will be described as an example. The multi-story parking apparatus 1 installed on the farthest side (the lowermost row in the drawing) from the passage. Furthermore, there is no passage already in the back. That is, the three-dimensional parking apparatus 1 farthest from the passage only enters the truck from the passage and does not pass through. This means that it is not necessary for the three-dimensional parking apparatus 1 to tilt the retractable support column 4 and place the upper pallet 2 flat.
Therefore, in the case of FIG. 2 (a), for the multi-story parking device 1 installed at the farthest side from the passage, the support column corresponding to the retractable support column 4 may be fixed upright. In this case, for example, the speed reducer 31, the chain block 30, the sprockets 35 and 37, the sprocket chain 36, the transmission rotating shaft 38, and the spring mechanism and the urging mechanism described with reference to FIGS. All the mechanisms related to the raising / falling of the tiltable column 4 can be omitted, and for example, the cost can be reduced.

  Moreover, depending on the situation and environment where the multi-story parking apparatus 1 is installed, a configuration in which the base portion 3 is omitted may be considered. In this case, the guard column 6, the guide rail 7, the column receiving plates 5a and 5b, the receiving column 14, the ladder 19, and the like, which are fixedly attached to the frame portion forming the base portion 3, etc., are attached to the ground. To be fixed and installed.

By the way, in addition to the three-dimensional parking apparatus 1 according to the present invention described so far, the present applicant has studied an inclined three-dimensional parking apparatus as shown in FIG.
24, first, a base 71 is installed on the ground, and the base 71 and the upper pallet 72 are connected by a fulcrum rotating shaft 74 on the front end side. It is configured as follows.
Further, the support columns 73 are attached to the base portion 71 as a pair on the left and right sides, and although not shown here, actually, an elevating mechanism for moving the upper pallet 2 up and down at the position of the support columns 73 is provided. ing.

In order to three-dimensionally park an automobile with the inclined three-dimensional parking apparatus 70, the following procedure is performed. Here, the automobile to be three-dimensionally parked is a truck as in the embodiment.
First, as shown in FIG. 24A, the upper pallet 72 is placed in a flat state so as to be stacked on the base portion 71. This is the prescribed lowering position of the upper pallet 72 in the inclined type multilevel parking device 70. In this case, the storage state is also achieved. In this state, the truck 100 to be parked in the upper stage is placed on the upper pallet 72.

  If the truck 100 is placed on the upper pallet 72 as shown in FIG. 24A, then the pallet rotation shaft 74 is used as a fulcrum as shown in FIG. Raise the rear end to the specified height. The position state shown in FIG. 24B is a prescribed ascending position of the upper pallet 72. In addition, the operation | movement to which this upper stage pallet 72 raises is obtained by the operation | movement of the raising direction by the raising / lowering mechanism with which the support | pillar 73 is equipped as above-mentioned. Further, the applicant of the present application employs a mechanism using electric power for the lifting operation by the lifting mechanism. In this case, the raising and lowering of the upper pallet 72 does not use the seesaw motion as in the multilevel parking apparatus 1 of the embodiment, but simply moves the upper pallet 72 up and down with the fulcrum rotating shaft 74 as a fulcrum. It takes a great deal of power. Therefore, it is determined that driving with electric power is realistic.

And as shown in FIG.24 (b), in the state which the upper stage pallet 72 was pulled up to the regular raise position, in the back side of a parking apparatus, a space is provided between the upper stage pallet 72 and the base part 71. FIG. It is formed.
Then, as shown in FIG. 24 (c), the truck 100 to be parked in the lower stage is moved backward from the space and parked. The parking position in the front-rear direction of the truck 100 is determined in consideration of preventing the rear side of the chassis portion 102 from hitting the slope of the upper pallet 72.

Such an inclined three-dimensional parking apparatus 70 can also three-dimensionally park a truck or the like with a relatively simple structure. Further, as shown in FIG. 24A, in a state where the upper pallet 72 is superimposed on the base portion 71, the track can be passed thereover.
However, in this case, the upper truck is parked with the one end portion of the upper pallet 72 tilted with the fulcrum as a fulcrum. Considering the workability of carrying out, the inclination angle cannot be increased unnecessarily. For this reason, the space between the upper stage pallet 72 and the base part 71 is also low, and the chassis part 102 of the truck 100 to be parked in the lower stage cannot be fully inserted. For example, FIG. 24C shows this problem because the distance L between the rear end portion of the upper pallet 72 and the rear surface of the cockpit portion 101 of the lower track 100 is correspondingly long. Yes.
For this reason, the distance from the front end of the upper truck 100 to the front end of the lower truck 100 when three-dimensional parking is performed as shown in FIG. End up.

When the applicant actually examined the inclined type multi-story parking apparatus 70, the following was obtained. Here, it is assumed that the same size of the truck 100 as assumed in the embodiment (the total length is 6840 mm, the length of the cockpit portion 101 is 2000 mm, and the height of the chassis portion 102 is 1100 mm) is parked.
In this case, as described in FIG. 24C, first, 8000 mm is required only for the entire length of the base portion 72 and the upper pallet 72. Further, the height of the rear end portion of the upper pallet 72 at the specified ascending position is 2300 mm. The actual distance between the front end of the upper track 100 and the front end of the lower track 100 is 12000 mm. For example, the distance between the front end of the upper track 100 and the front end of the lower track 100 in the multi-story parking apparatus 1 of the embodiment is within 8000 mm. It has been long.
In addition, as described above, the inclined type multi-story parking apparatus 70 shown in FIG. 24 also has a significant difference from the present embodiment in that it is necessary to use an electric power mechanism for raising and lowering the upper pallet 72 as a real problem. .

In the description of the embodiment, a specific configuration example in the case where the truck is three-dimensionally parked is described. However, depending on the technique based on the present invention, it is possible to three-dimensionally park a vehicle other than the truck. .
That is, in consideration of the size and shape of the automobile that is supposed to be parked, the weight balance, the size and shape of the main parts constituting the three-dimensional parking apparatus 1 as an embodiment, the fulcrum position (center of gravity) of the upper pallet 2, etc. If it is set as appropriate, it is possible to deal with various ordinary vehicles. In particular, in motor pools and the like, the types of vehicles to be parked (vehicle types) are not limited to trucks and ordinary vehicles, but are almost determined. Therefore, the design of the three-dimensional parking apparatus 1 according to the type of vehicle is easy. It becomes.
Of course, the seesaw type multi-story parking apparatus based on this invention can be utilized not only as a motor pool but as a multi-story parking apparatus installed in a house or a general parking lot. In the case of a general parking lot, various types of vehicles are parked. For example, as an ordinary vehicle, a so-called FF vehicle (front engine, front-wheel drive vehicle) has become common in recent years. Such an FF vehicle is usually in a weight balance with a center of gravity on the front side of the automobile body. With this as a premise, in the same manner as described above, if the size and shape of the main parts constituting the multi-story parking apparatus 1 and the support position (center of gravity) of the upper pallet 2 are appropriately set, a seesaw type corresponding to a wide range of vehicle types A three-dimensional parking apparatus can be obtained.
