Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a two-stage parking system capable of parking an automobile in two upper and lower stages.

[0002]

2. Description of the Related Art Conventionally, as a parking lot for automobiles, a flat parking lot has been widely used in which the land is leveled or paved, and the land is divided or drawn for each car. In recent years, with the shortage of land for parking lots, a multi-level parking device in which a vehicle is parked three-dimensionally in order to effectively use the land is becoming widespread.

Specifically, for example, there is a two-stage parking system in which a car is housed in upper and lower two tiers and about twice as many cars can be parked per unit area as compared with a flat parking lot. It has been put to practical use. In such a two-stage parking device, the simplest one is that a plurality of vehicle accommodating parts are formed side by side in a main body part built on a foundation provided on the ground, and the vehicle accommodating parts are respectively arranged in a vertical direction. An elevating pallet that can be moved to and from is provided, and the vehicle is placed on the floor surface of the main body and the elevating pallet in each vehicle accommodating portion.

However, in such a simple two-stage parking apparatus, when a vehicle is placed below a certain lifting pallet, it is necessary to temporarily move the vehicle out of the parking apparatus. On the other hand, there is a problem that it is troublesome to put the car in and out because the car cannot be taken in and out.

Therefore, each vehicle accommodating portion is provided with an elevating pallet that can move vertically, and a traverse pallet that can move laterally across a plurality of vehicle accommodating portions near the floor of the main body is provided. A two-tiered parking system has been proposed in which vehicles can be placed on both pallets.
(For example, JP-A-57-21671 and JP-A-61)
-21460). In the conventional two-tiered parking system having the lifting pallet and the traversing pallet as described above, the number of the traversing pallets is usually set to be one less than the number of vehicle accommodating units (the number of lifting pallets). As a result, it is possible to make an arbitrary vehicle accommodating portion in a state in which the transverse pallet is not arranged, that is, a state in which the vehicle can be taken in and out of the elevating pallet.

If only one vehicle housing portion is provided, the transverse pallet cannot be moved to the left and right, so a two-tiered parking system of the type without a transverse pallet,
That is, there is no choice but to use a two-tiered parking system of the type in which when a car is taken in and out of a lifting pallet, the car below it must be taken out of the parking system.

[0007]

By the way, when there is a vacant land on the right side or the left side of the existing two-tiered parking system, it may be planned to add a parking system to this vacant space. In such a case, since it is extremely difficult to expand the existing two-stage parking device, another two-stage parking device has to be newly provided next to the existing two-stage parking device. In this case, when the number of parked vehicles is increased by only two, as described above, a two-stage parking device of a type in which a car below the car is temporarily taken out of the parking device when the car is taken in and out of the lifting pallet is provided. Since there is no such thing, there is a problem that it takes time to put in and take out a car for newly installed parts.

Further, when the number of parking lots is increased by three or more, a two-stage parking apparatus of a type having an elevating pallet and a traversing pallet can be provided. Each two-tiered parking device must have a space for moving the traversing pallet, so the number of cars that can be parked is one less than when one large two-tiered parking device is installed. Therefore, there arises a problem that the land cannot be effectively used effectively.

Moreover, in the conventional two-stage parking apparatus, since the main body is fixed to the concrete foundation or the like provided on the ground, it is extremely difficult to move the two-stage parking apparatus. Therefore, for example, when there are relatively narrow vacant spaces on the left and right of the existing two-tiered parking device, the two-tiered parking device is moved to either the left or right to create a relatively large vacant lot, and parking is performed here. Effective use of land cannot be achieved by methods such as adding equipment. In addition, the conventional two-tiered parking system cannot reduce the size of the existing two-tiered parking system. Therefore, if a part of the land on which the existing two-tiered parking system is installed is used for another purpose, the existing two-tiered parking system will be used. There is no choice but to remove all multi-tiered parking devices.

Further, in the conventional two-stage parking apparatus, the lifting pallet is normally supported (fishing) by the main body through a chain or the like. When the chain is cut, the lifting pallet is lifted. However, there is a problem in that the vehicle placed on the lifting pallet or the vehicle placed below it is damaged.

The present invention has been made to solve the above-mentioned conventional problems, and can be easily expanded / reduced or moved to sufficiently utilize the parking lot effectively, and An object of the present invention is to provide a two-stage parking device capable of preventing the lifting pallet from falling when a chain or the like supporting the lifting pallet is broken.

Similarly, the base plate 39m attached to the lower end of 4m is also fastened to both rear bases 28 using four fastening bolts at a predetermined position near the contact portion of the adjacent rear bases 28. In this way, each pillar 33,34
The main body 2 is assembled by connecting to the corresponding bases 26 and 28, and connecting the floor portion F and the support portion S. The front part of each front base 26 has a ground 1 and a floor F, respectively.
A skirt 45 for eliminating the step between and and facilitating the taking in and out of the automobile 6 is attached using six attaching bolts 47.

As described above, since the main body 2 has the divided assembly structure, the two-stage parking apparatus GS can be easily expanded or reduced, and the parking lot can be effectively used. Hereinafter, the expansion method of the existing two-stage parking apparatus GS including the five vehicle accommodating portions 3 will be described by taking the case where the vehicle accommodating portion 3 is increased by one on the left side as an example. In this case, first, movable objects or accessories such as the lifting pallet 4 and the traversing pallet 5 arranged in the leftmost vehicle housing 3 (hereinafter referred to as the leftmost vehicle housing 3) are removed. Then, the fastening connecting the basic member belonging to the leftmost vehicle housing portion 3 and the basic member belonging to the innermost vehicle housing portion 3 (hereinafter, simply referred to as the inner vehicle housing portion 3) located second from the left end All the bolts or the connecting plates are removed, and the main body portion 2 is composed of a first assembly that includes only the basic members that belong to the left-end vehicle housing portion 3 and a second assembly that includes only the basic members that do not belong to the left-end vehicle housing portion 3. Split into.

Next, a new basic member corresponding to the basic member belonging to one inner vehicle housing portion 3, in other words, a basic member capable of assembling one inner vehicle housing portion 3,
That is, one inside front base 26m, one inside middle base 27m, one inside rear base 28m, one front connecting beam 31, one rear connecting beam 32, and one An inner front pillar 33m, one inner rear pillar 34m, one front lateral beam 35, one rear lateral beam 36, and one vertical beam 37 are prepared.

The respective basic members thus prepared are arranged in the same manner as the existing inner vehicle accommodating portion 3, and the fastening bolts 46 and 48 and the connecting plate 40 are provided on the left side of the second assembly.
Are sequentially connected using. As a result, a new third assembly is obtained which has a structure of the left end portion similar to that of the second assembly, and has one vehicle housing 3 more than the second assembly.

Next, the right end of the first assembly and the left end of the third assembly are connected to the fastening bolts 46 and 48 and the connecting plate 40.
Connect using and. As a result, the vehicle housing portion 3 is
The main body part 2 having two parts is obtained. If movable objects or accessories such as the lifting pallet 4 and the transverse pallet 5 are arranged in the left end of the new main body portion 2 and the second vehicle accommodating portion 3 from the left, respectively, the two-stage parking system GS can be installed. Expansion is complete,
It is a two-stage parking system GS that can park up to 11 cars.

In this way, the two-stage parking system GS is
Can be easily expanded. When the number of vehicle housings 3 is increased by two or more, the number of basic members to be added / connected between the first assembly and the second assembly may be increased according to the increased number. Also, when expanding the vehicle housing part 3 to the right side,
The procedure is, of course, the same as in the above case, except that the right and left are interchanged.

When the size of the two-stage parking system GS is reduced, for example, when the left side vehicle accommodating portion 3 is reduced by one, it belongs to the second vehicle accommodating portion 3 from the left, that is, the leftmost inner vehicle accommodating portion 3. The basic member is the applicable fastening bolt 4
After removing and removing 6,48 (after dissociation), if the remaining two assemblies are reassembled, the two-tiered parking system GS with one less vehicle housing 3 is used, that is, a maximum of seven vehicles. A two-stage parking system GS that can park a vehicle is obtained. In this way, the two-stage parking system GS is extremely easy to expand and contract, and therefore effective use of the parking lot can be achieved.

As is apparent from FIGS. 6 and 7, the front rail 24 and the rear rail 25 are also respectively provided in the vehicle accommodating portions 3 respectively.
Although the divided assembly structure is divided for each, the laying structure of the rails 24, 25 will be described below. 6 and 1
As shown in FIG.
Each front rail 24 is welded to a predetermined position on the upper surface of the corresponding front base 26. As is apparent from FIG. 6, the front rail 24 is shorter than the front base 26 when viewed in the left-right direction. Therefore, the front rail 24 is near the left end portion and the right end portion of the front base 26, respectively. Missing part (rail missing part)
Is occurring.

As is clear from FIGS. 14 and 15, a base plate 38 is arranged at the rail missing portion of each front base 26. Here, the base plate 38 is arranged in the left-right direction so as to just fill up the rail defect portion, while in the front-rear direction, the rear end face L thereof is arranged so as to coincide with the rear end face of the front rail 24. Moreover, the height of the base plate 38 is equal to that of the front rail 2
It has the same height as 4. Therefore, the front wheels 21 of the traverse pallet 5 can roll smoothly on the front rails 24 or the base plate 38 from side to side without any hindrance.

In this way, the front rail 24 is connected to the front base 2
It is the front rail 2 that is to be damaged near both left and right ends of 6
This is for facilitating the welding of the No. 4 to the front base 26. That is, when such a rail defect portion is not provided, the front rail 24 has to be welded to the left and right end surfaces of the front base 26, but this makes welding difficult, and the left and right end surfaces of the front base 26 are not welded. This is because distortion occurs. That is, by providing the rail deficient portion in this way, the front rail 24 can be easily welded to the front base 26, and the abutting property between the adjacent front bases 26 can be improved.

A driven gear 63 that meshes with the drive gear 62 is attached to the rear end of the drive shaft 59. Therefore, the motor 2
When the second output shaft 61 rotates, this rotational force is transmitted to the right rear wheel 23 (driving wheel) via the drive gear 62, the driven gear 63, and the drive shaft 59, and further to the right front side via the axle 20. The pallets 5 are transmitted to the wheels 21, and thereby the transverse pallet 5 travels (moves) in the left-right direction. Of course, the traveling direction of the traverse pallet 5 can be switched by switching the rotation direction of the motor 22.

By the way, in the two-stage parking system GS, there are three kinds of means for preventing the lifting pallet 4 from falling, lowering or tilting when the hoisting chain 10, the interlocking chain 12 or the roll prevention chain 53 is broken. Elevating pallet fall prevention means is provided, but these elevating pallet fall prevention means will be described below.

A wire rope 84 connected to the portion 83s, and a second coil spring 85 having an upper end connected to the arm portion 83s using a fastener 86 and a lower end fixed to the rear support portion 4b using a fastener 87; It is composed of. The second coil spring 85 is normally stretched in the S ₄ direction, and therefore normally biases the arm portion 83s in the S ₃ direction. In addition, the wire rope 84 supports the arm portion 83s in the S ₆ direction and suppresses the displacement of the arm portion 83s in the S ₅ direction.

Here, in a normal state, as shown in FIGS. 21 and 22, the second rotation restraining member 83 is arranged at the position rotated to the S ₂ side, and at this time, The rotation restraining member 83 does not restrict the rotation of the second rear rotation member 19. When the lifting chain 10 is broken, the upper end of the wire rope 84 is no longer supported by the link member 8 (the lifting chain 10), so the wire rope 84 does not restrict the displacement of the arm portion 83s. Therefore, the second rotation restraining member 83 is rotated in the S ₁ direction by the urging force of the second coil spring 85 in the S ₃ direction, and the second rotation inhibiting member 83 is interposed between the second rear rotation member 19 and the front wall of the rear column 34.

Third lifting pallet fall prevention means is provided for preventing. It should be noted that the third lifting pallet fall prevention means is provided at the left rear end of each lifting pallet 4. The third lifting / lowering pallet fall prevention means is similar to the case of the second lifting / lowering pallet fall prevention means in that the rotation shaft 82, the second rotation restraining member 83 (claw), the second coil spring 85 and the second coil spring 85 are fastened. Tools 86, 87 are provided, but these respective members 82, 83, 85, 86, 87
In order to avoid duplication of description, individual description will be omitted.

Further, the third lifting pallet fall prevention means further includes a sprocket 9 which is rotatably supported by a rotation shaft 91 and meshes with a rolling prevention chain 53.

The (upper arm portion 93) is arranged at a position rotated to the T ₄ side by the tension of the roll prevention chain 53. At this time, the lower arm portion 95 has the arm portion 83 of the second rotation restraining member 83.
It abuts against s and suppresses displacement of the arm portion 83s in the S ₅ direction. Therefore, the second rotation restraining member 83 is arranged at the position rotated to the S ₂ side, and the second rotation restraining member 83 does not restrict the rotation of the second rear rotation member 19.

When the anti-sway chain 53 is broken, the connecting arm 90 (upper arm portion 93) cannot be pulled in the T ₄ direction depending on the chain 53, so that the third coil spring 97 is attached in the T ₁ direction. The connecting arm 90 is rotated in the T ₃ direction by the force. At this time, the lower arm portion 95 does not come into contact with the arm portion 83s of the second rotation restraining member 83, and the lower arm portion 95 no longer restricts the displacement of the arm portion 83s. Therefore, the second rotation restraining member 83 is rotated in the S ₁ direction by the urging force of the second coil spring 85 in the S ₃ direction, and the second rotation inhibiting member 83 is interposed between the second rear rotation member 19 and the front wall of the rear column 34. Biting in and stopping the rotation of the second rear side rotation member 19. Therefore, the lifting pallet 4 is prevented from falling, lowering or tilting.

As described above, in the two-stage parking apparatus GS, even if any of the chains 10, 12, 53 is cut, the corresponding lifting / lowering pallet drop preventing means ensures that the lifting / lowering pallet 4 is dropped, lowered or tilted. Therefore, the two-stage parking system GS or the vehicle 6 is not damaged.
