Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement of a two-level vertical parking system.

This kind of conventionally known two-stage multilevel parking system has a lifting drive mechanism such as a hydraulic cylinder device for raising and lowering the upper parking garage, and a column-structured elevator guide mechanism located at the center of the upper parking deck in the longitudinal direction. They are usually arranged in pairs on the left and right near the area. This is because, considering that a vehicle is parked on the upper parking platform and a load is loaded on it, it is desirable to provide a structure that supports the load near the center of gravity of the upper parking platform.

However, with such a configuration, the following difficulties are pointed out when using the device. Firstly, when a vehicle enters the upper parking platform, the upper parking platform is lowered to the ground surface. The pillar structure type structure that has been lowered will be in a state that protrudes above the lowered upper parking platform. For this reason, if we consider the entry and exit of a vehicle as, for example, reversing and entering onto the upper parking platform,
There is a problem in that the driver must be very careful to avoid the rear part of the vehicle coming into contact with the structure. That is, if an incoming vehicle comes into contact with a portion of the pillar structure, both will be damaged, and repairing both the mechanism and the vehicle will be a heavy burden. Also, as a second problem,
When a vehicle is moved in and out of the lower parking platform with the upper parking platform raised and stationary at a required position above, there is a problem that the pillar structure becomes an obstacle when a driver gets on and off the parked vehicle. In other words, the structure is usually located at a position where it interferes with opening and closing of the front seat door of the vehicle.

Therefore, in order to solve this difficulty, for example, instead of arranging the pillar structure part for lifting up and down at the middle part in the longitudinal direction of the upper parking platform, it may be possible to arrange it at the rearmost part. If such an arrangement is simply adopted, the upper parking platform will be cantilevered at its rear end, with the front side as the free end, with sufficient consideration given to the strength and rigidity of the cantilevered structure. Therefore, each structural member needs to have great strength. As a result, it is necessary to make the parking device from a member with sufficient structural strength, and the overall structure of the device becomes large and considerably heavy.
Therefore, it is conceivable to support the upper parking platform, which has a rectangular plan view, with an elevator drive mechanism and an elevator guide mechanism having a pillar structure arranged at the four corners of the rectangle. In this way, the problem of the above-mentioned mechanisms getting in the way of the driver getting in and out of the parked vehicle can be solved.
However, the problems of the device becoming larger and having many parts remain unresolved, and furthermore, a pillar structure is installed at the front side of the parking device, so drivers need to be careful when entering and exiting the vehicle. will actually increase.

The present invention has been made in view of the various points mentioned above, and employs a Caesars-type mechanism in which two crossed legs forming an X-shape when viewed from the side move to open and close as a lifting guide mechanism, and this is used as a parking device. By placing the vehicle in the rear half, the two-tier three-dimensional structure reduces the operational burden on the driver when entering and exiting the upper or lower parking lot, and also minimizes the number of structures that get in the way of getting on and off the vehicle. The purpose is to provide parking equipment.

Another object of the present invention is to configure the upper parking platform that moves up and down so as to cause a slight upward swing in the up-and-down motion, thereby reducing the lifting height of the up-and-down driving device disposed at the rearmost part of the device. To provide a two-tiered multilevel parking device which is highly likely to be applied to installation locations with spatial restrictions by making it possible to increase the height of a vehicle mounted on an upper parking platform as much as possible. It's there.

The features of the two-stage multilevel parking system according to the present invention that achieves the above objects are that it is fixed on a base,
A lower fixed structure including a pair of parallel lower frame bodies arranged along the left and right sides of a parked vehicle, and a lower fixed structure including a pair of parallel lower frame bodies arranged parallel to the upper position of this lower fixed structure and corresponding to the left and right lower frame bodies. Between an upper parking lot including a pair of upper frame bodies, and the upper frame body and the lower frame body,
Two X-shaped legs are interposed to connect these at a position biased towards the rear half side in the front-rear direction, and the two legs open and close around the intersection point, thereby raising and lowering the upper parking platform. A pair of left and right scissor-type elevating guide mechanisms provided to guide the upper frame body and the lower frame body, and an elevating mechanism arranged to connect the upper frame body and the lower frame body at the rearmost end positions in the front and back direction, and which drives the upper parking platform up and down. The scissor lifting guide mechanism includes a driving device, and the scissor lifting guide mechanism includes two pivot points located on the front side in the front-rear direction out of four pivot connection points between the ends of the two legs and the upper frame body and the lower frame body. The pivot connection point is configured to move in the front and back direction with respect to the two pivot connection points located on the rear side in the front-rear direction to allow opening and closing movements of the two legs, and the lower frame body is moved on the rear side. One leg connected to the upper frame body on the front side and connected to the upper frame body on the front side is provided longer than the other leg connected to the upper frame body on the rear side and connected to the lower frame body on the front side. It's there.

The embodiment of the present invention shown in FIG. 2 will be explained below in comparison with the comparative example shown in FIG.

Comparative Example In FIG. 1, reference numeral 2 denotes a lower frame body forming a part of the lower fixing structure of the multi-story parking device, and is fixed to extend for a certain length from the rear end to the front side along the left and right sides of the vehicle parking position. This lower fixing structure is a necessary connecting member (not shown) that integrates the left and right lower frame bodies 2.
It consists of a fixing device (not shown) such as a stud bolt for fixing the lower frame body 2 to the base 1, and a pallet for a lower parking platform to be installed as necessary. A guide portion 3 is provided on the front end side of the guide portion 3 for movably supporting a pivot connection point rotatably supporting the lower end of one leg of a scissor-type guide mechanism to be described later.

The parking device lower fixing structure is provided in the shape of a rectangle or a rectangular frame that is fixed with a small thickness on the base 1 by a pair of left and right lower frames 2 and a connecting member between them. 4 is a pair of opening/closing legs 5, 9
The lower end of one leg 5 is pivotally connected to the rear end of the lower frame body 2, and the upper end is connected to the upper parking platform 12, which will be described later. It is pivotally connected to a guide portion 14 formed on the left and right upper frame bodies 13 so as to be movable in the front-back direction and rotatable. Reference numerals 7 and 8 are shafts for pivotally connecting the upper and lower ends, and the shaft 8 on the upper end side is guided by a guide portion 14 formed of, for example, a rail extending in the front and back direction formed on the upper frame of the upper parking platform 12. It is now possible to move in the same direction.

The other leg 9 has its lower end attached to the guide portion 3 formed in the lower frame body 2 of the lower fixing structure.
0, and is pivotally connected to the rear end of the upper parking platform 12 via a shaft 11. Nao 6
is a central axis that rotatably connects the intersection center points of the pair of legs 5 and 9.

In the scissor-type lifting guide mechanism of this example, the pair of legs 5 and 9 are of equal length and are provided symmetrically about the central axis 6, so that the shaft 7, which is the pivot connection point of the end of each leg 5 and 9, 8, 10, and 11 are constructed so as to always form the respective apex positions of the rectangle, and therefore, the upper parking platform 12 that is guided up and down by this always maintains a parallel relationship with the surface of the base 1. Become.

The upper parking lot 12 includes a pair of left and right upper frames 13,
It is comprised of a connecting member (not shown) that connects these left and right upper frames 13, and a pallet (not shown) that is supported by these upper frames and connecting members and forms a direct parking surface for the vehicle.

Reference numeral 16 denotes a hydraulic cylinder device as a drive mechanism for raising and lowering the upper parking platform 12, and in this example, the cylinder body 1 is installed so as to extend upward from the rearmost part of the upper parking platform 12 via the bracket 15.
7, the lower end of the piston rod 18 is pivotally connected to the rearmost part of the lower frame body 2 of the lower fixed structure.
Further, the upper end side of the piston rod 18 is configured to be moved in and out relative to each other by hydraulic pressure. Although the hydraulic piping of the hydraulic cylinder device 16 is not shown in the figure, by transmitting the hydraulic pressure, the cylinder body 17 moves upward while leaving the piston rod as it is, and by removing the hydraulic pressure, the cylinder body 17 moves upward.
moves downward. 19,2
0 is a parked vehicle.

Thus, the cylinder body 17 is removed from the state shown in the figure.
When the hydraulic pressure inside is released, as the cylinder body 17 descends, the scissor-type guide mechanism gradually collapses so as to crush the legs 5 and 9, and the upper parking platform 12 descends while maintaining a state parallel to the base. It reaches the lowest point and stops. Therefore, in this state, vehicles can enter and exit the upper parking platform 12.

Next, by force-feeding hydraulic pressure to the cylinder body 17, the upper parking platform 12 rises while maintaining a parallel state, contrary to the above, and is stopped when it reaches its highest point. remains stationary in position. In this state, vehicles can enter and exit the lower parking space.

Note that when the upper parking platform 12 reaches the lowest position in this comparative example, the upper parking platform 12 is normally connected to the base 1 due to the lower fixing structure, guide mechanism, etc.
Since it is unavoidable that the position is higher than the upper surface of the parking platform 12, it is practical to either form a bulge at the front of the parking device on the base 1 in order to allow vehicles to smoothly enter and exit the parking platform 12, or It is preferable to form a forward and downwardly inclined hanging part at the frontmost part. Alternatively, the connecting member of the lower fixing structure may be omitted so that the upper parking platform can be lowered until it touches the base.

In the multilevel parking system of the comparative example having the above-described configuration, the weight of the upper vehicle acting on the upper parking platform 12 is controlled by the scissor type elevating guide mechanism 4 and the hydraulic cylinder device 1.
6, it is possible to stably support it using a relatively simple structural member, and the scissor-type guide mechanism 4 is provided in the rear half of the parking device, and the hydraulic cylinder device 16 is mounted on the parking device. Because of this structure, when the upper parking platform 12 is lowered to the lowest point, the structural members projecting upward from the upper parking platform 12 are connected to the cylinder body of the hydraulic cylinder device 16 at the rearmost portion. 17 alone has the advantage that the effect that hinders the entry and exit of the vehicle 20 is significantly reduced compared to the conventional one, and when the upper parking platform 12 is stationary at the highest point position shown in the figure, the scissors Two legs 5 and 6 of the mold guide mechanism
Since the vertical middle part of the vehicle 19 forms a gap that is narrowed toward the rear, the door can be opened and closed easily when getting on and off the front seat of the vehicle 19, and the driver can get in and out of the vehicle 19 smoothly, which is an unprecedented advantage. There is.

Another advantage is that if it is lowered, there are no large protruding parts such as pillars as in the conventional type, and it is aesthetically advantageous.

Example This example further improves the above-mentioned comparative example in which the upper parking lot is raised and lowered while always maintaining a parallel relationship with the base, and the front part of the upper parking garage is slightly tilted up and down as it goes up and down. By providing the parking device with swinging motion, the lifting stroke of the upper parking platform required to obtain the required height for the lower parking space of the parking device is reduced, and the parking space is also reduced.

For such a configuration, a pair of legs of the scissor-type guide mechanism are made of unequal length, and the upper end position of one leg, which is pivotally connected to the front-rear middle of the upper parking platform so as to be movable in the same direction, must be compared. This is set by extending from the rectangular apex position of the scissor-type guide mechanism explained in the example on the extension line of the leg, and the other configurations are basically the same as the comparative example, so the same parts and devices are designated by the reference numeral. is shown with 100 added to it, and its explanation is omitted.

That is, in FIG. 2, 101 is the base, 102 is the lower frame of the lower fixing mechanism, 103 is the guide part, and 104
105 and 109 are scissor-type guide mechanisms, 105 and 109 are the legs thereof, 106 is a central axis that is the center of the opening and closing movement of these legs, and 107, 108, 110, and 111 are axes that are the pivot points of the legs 105 and 109, respectively. , 112 is the upper parking platform, 113 is the upper frame body, 11
4 is a guide portion formed on the upper frame body 113 of the upper parking platform 112; 115 is a rearmost portion of the upper frame body 113 and the cylinder body 11 of the hydraulic cylinder device 116;
7, a bracket 118 is a piston rod, and 119 and 120 are parked vehicles.

The feature of this embodiment is the scissor type guide mechanism 1.
The structure of the pair of legs 105, 109 of 04 is shown in the figure from the central axis 106 to the pivot connecting shafts 107, 11.
0,111 are the same length, and the length to the pivot connection shaft 108 is slightly longer, and the pivot connection shaft 108 is located near the extension line of the leg 109. It lies in being.

In this arrangement, since the pivot connection shaft 108 is in the substantially extending direction of the leg 109, when the upper parking platform 112 is raised to the maximum point shown in the figure, the upper parking platform 112 has a front section. A state in which the upper parking platform 112 is lowered to the lowest point position by creating a gentle inclination with the side facing upward and by placing the pivot connection shaft 108 slightly below the extension line of the leg 109. (In other words, when the legs 105 and 109 are substantially overlapping and parallel to the base 101), the front side of the upper parking platform 112 is provided with a very gentle downward slope. This is to allow the front portion of the vehicle 120 to be brought into contact with the upper surface of the base 101 to allow the vehicle 120 to move in and out smoothly.

Therefore, the leg 109 is longer than the other leg 105, and the connection position of the pivot connection shaft 108 to the upper frame body is set near a line extending in the longitudinal direction of the leg 109. That's good.

According to the above configuration, the same effects as described in the comparative example can be obtained, and furthermore, the vertical stroke h of the hydraulic cylinder device 116 is reduced at least on the front side of the lower parking space in this type of multi-story parking system. For the required height H to be satisfied, H>h
It can be set in the relationship of
In addition, the required parking volume can be reduced by lowering the topmost point of the vehicle parked on the upper side, and there is an advantage that the suitability is greatly increased especially in cases where there are large volume constraints such as in the basement of a building. Furthermore, when the upper parking platform is raised, the upper parking platform tilts forward, preventing cars from deviating from the front of the parking platform, and rainwater and filth flow to the rear of the parking platform, preventing people and vehicles from getting dirty when entering and exiting the vehicle below. There is also the benefit of eliminating

In addition, in such a multi-story parking system, the lifting force of the hydraulic cylinder device on the upper parking platform acts at right angles, so it is sufficient to generate a pushing force of the same degree as the applied load, and the lifting drive mechanism is activated at the highest point position. The hydraulic cylinder device can be downsized by appropriately adopting a structure in which the operation of the lifting guide mechanism is mechanically locked. Although the hydraulic cylinder device of the present invention is not limited to this example, in particular, the piston rod 118 is used as shown in the figure.
If the hydraulic cylinder device 1 is slidably supported to be removable into and out of the opening at the lower end of the cylinder body 117, and is connected and supported at the lower end of the cylinder body 117 to the upper parking platform 112 as shown in the figure, the hydraulic cylinder device 1
The buckling strength of the piston rod 116 can be considered within the range of the column height approximately corresponding to the length of the piston rod 118, and there is an advantage that the diameter can be reduced.

Furthermore, another effect of the present invention is that it is possible to effectively improve the efficiency of assembling the structural parts of each part of the apparatus in a factory and transporting the apparatus from the factory to a required installation location. That is, as is clear from the illustrated configuration, the parking device according to the present invention includes at least a hydraulic cylinder device, a lower fixing structure, an upper parking platform, and a scissor-type guide mechanism that are assembled in a factory and then retracted, that is, the upper parking platform 112 is lowered. Several existing parking devices of this type can be transported in piles, and while most of the existing parking devices are assembled on-site, requiring a considerable amount of time for on-site assembly, the device of the present invention has extremely large advantages.

As described above, the two-stage multilevel parking system according to the present invention has a relatively simple structure and has various extremely excellent effects, and its usefulness is extremely great.
