The system is selected and applied depending on the type of building to be applied, the installation portion, the number of units accommodated, and the like. For example, a vertical circulation system, an elevator slide system, and an elevator system are suitable for installation in a ground portion, and a multilayer circulation system and a horizontal circulation system are suitable for installation in an underground portion. Among them, in urban space,
A vertical circulation system that enables a large number of units to be accommodated in a small space is often used.

FIG. 8 is a schematic view of a main part of a conventional vertical circulation type parking apparatus, and FIG. 9 is a schematic view of a driving device provided on the upper part of the vertical circulation type parking apparatus.

As shown, the upper side wall of a building (not shown)
An inwardly projecting beam portion 102 is formed integrally with the 101, and a girder 103 is provided between the beam portions 102 that face each other. On this girder 103, there is a support frame 104
A pair of front and rear upper sprockets 105 are rotatably supported via a sprocket, and a sprocket gear 106 is fixed to the upper sprocket 105. And this girder 1
A driving device 107 for rotating the pair of front and rear upper sprockets 105 is provided at a central portion of 03. In addition, a pair of front and rear lower sprockets are rotatably supported at the lower part of the building via support frames (not shown).

In the driving device 107, a motor 108 is provided on the girder 103, and a driving shaft 109 of the motor 108 is connected to a speed reducer 111 via front and rear connecting shafts 110. The sprocket gear 106 is meshed with the intermediate gear 113 via the intermediate gear 113. In addition, 114 is a brake device. An endless chain 115 is wound around each upper sprocket 105 and the lower sprocket, and a triangular attachment 116 consisting of two links is attached to the chain 115 at predetermined intervals. A cage 118 having a pallet 117 on which the vehicle A can be mounted is suspended from the tip of the 116. In addition, chain 1 is attached to attachment 116.
A linear guide roller 119 is attached to the connection with the linear guide roller 15, and a curved guide roller 120 is mounted on the shoulder of the cage 118, and the linear guide roller 119 is mounted along a linear portion of the chain 115. The inside of the guide rail 121 is movable, and the curved guide roller 120 is freely movable within the curved guide rail 122 provided at the upper and lower portions.

Accordingly, when the motor 108 is driven, the driving force is transmitted via the drive shaft 109 and the connecting shaft 110 to the front and rear reduction gears 11.
The reduced driving force is transmitted to the front and rear sprocket gears 106 via the output gear 112 and the intermediate gear 113, and the upper sprocket 105 integrated with the sprocket gear 106 rotates in the same direction. Then, the chain 115 wound around the upper sprocket 105 and the lower sprocket moves, and the attachment 11
Cage 11 with pallet 117 suspended through 6
8 can be circulated. At this time, when the cage 118 moves linearly, the linear guide rollers 119
By moving inside 21, the twist of the chain 115 is prevented,
When the cage 118 moves on a curve, the curve guide roller 120 moves in the curve guide rail 122 to prevent the cage 118 from swinging.

[0007]

As described above, the conventional vertical-circulation-type parking device has an attachment 1 attached to the chain 115.
By suspending the cage 118 through 16, the chain 115
When the is moved in an arc by the upper sprocket 105 or the lower sprocket, the moving speed is increased to prevent contact between the preceding and following cages 118. Therefore, when the cage 118 moves linearly, the attachment 116 protrudes outward from the chain 115 that moves up and down, and the cage 118 is hung at the distal end thereof.
The load alone or including the automobile A acts on the chain 115 as a bending moment. When a bending moment acts on the chain 115 during the linear movement of the chain 115, the chain 115 bends as shown in FIG. 10, causing the cage 118 to swing, or changing the interval between the preceding and following cages 118. As a result, there is a problem that the cage 118 cannot be transported smoothly.

For this reason, conventionally, a linear guide roller 119 is attached to a connecting portion between the attachment 116 and the chain 115, and when the cage 118 moves linearly, the linear guide roller 119 is moved while being restrained by the linear guide rail 121. Thus, the bending of the chain 115 is prevented. Although the bending of the chain 115 is prevented by the linear guide rollers 119 and the linear guide rails 121, the cage 118 is conveyed correctly. However, in practice, the chain 115 receives a bending moment as before (see FIG. 10), and Guide rail 12
A lateral stress is applied to 1 from the linear guide roller 119. For this reason, the strength of the linear guide rail 121 must be sufficiently ensured, and there is a problem that the device is increased in size and weight and the manufacturing cost is increased.

The present invention has been made to solve such a problem, and the bending moment acting on the chain during the linear movement of the cage is reduced to facilitate the operation and to simplify the device and reduce the weight. It is an object of the present invention to provide a vertical circulation type parking device capable of reducing manufacturing costs as much as possible.

[0010]

In order to achieve the above-mentioned object, a vertical circulation type parking apparatus according to the present invention rotatably supports a pair of front and rear upper sprockets at a predetermined interval at an upper position in a building. On the other hand, a pair of front and rear lower sprockets are rotatably supported at predetermined intervals at a lower position in the building, and a chain is hung between the upper sprocket and the lower sprocket, respectively, and the chain is stretched in the longitudinal direction of the chain. A hanging device is connected at a predetermined distance, and a cage for mounting on a vehicle is suspended between the pair of front and rear hanging devices so as to be freely rotatable in the left-right direction, and the upper sprocket or the lower sprocket is driven by a driving device. In a vertical circulation type parking device that vertically circulates the cage by vertically moving the chain by rotating any one of the above, A link member having one end pin-connected to one end of one link of a chain in which a number of links are pin-connected and the other end connected to a suspension shaft of the cage; and the other end of the link member. And an outrigger whose leading end abuts on a pin immediately below a pin to which one end of the link member is connected when the chain moves longitudinally to disperse the cage load.

The pallet 31 on which the automobile A can be mounted is attached to the lower part of the cage 18 so that the pallet 31 can rotate freely in the left-right direction via 2b.

The attachment 17 is shown in FIGS.
As shown in FIG. 3, one end of each link 16a of the chain 16 formed by connecting a number of links 16a to pins 33 is connected to pins 33, and the other end is coaxial with the suspension shafts 32a and 32b of the cage 18. Two linked links 1

7a and the outrigger 17b are integrally formed,
Only the outrigger 17b and the link 17a adjacent to each other may be integrally formed.

With this configuration, the hydraulic cylinders 24 and 25 are supplied and discharged with hydraulic pressure, and the upper sprocket 13 is rotated together with the rotating body 23 by expanding and contracting the hydraulic cylinders 24 and 25. Upper sprocket 13
The chain 16 wrapped around the lower sprocket 15 is moved between the chain 16 and the attachment 17.
Can be vertically circulated through each of the cages 18 attached thereto.

As shown in FIGS. 1 and 3, the cage 18 is suspended from the chain 16 via the attachment 17 so that when the chain 16 moves in an arc shape by the upper sprocket 13 or the lower sprocket 15, The speed is increased to prevent contact between the preceding and following cages 18.

As described above, when the cage 18 moves up and down linearly between the upper sprocket 13 and the lower sprocket 15, the load including the cage 18 alone or the vehicle A acts on the chain 16 as a bending moment. As a result, a stress is generated which causes the chain 16 to bend significantly.

However, in this embodiment, as shown in FIG. 5, at this time, the two links 1 of the attachment 17 are used.
7a and the lower outrigger 17b of the two outriggers 17b disperse the load between the upper and lower three pins 33 so that the two links 16a of the chain 16 are aligned as shown by the broken lines in the figure. Accordingly, the arm is bent and deformed so that the length of the arm of the moment becomes approximately twice as long as that of the conventional example shown in FIG.

As a result, the lateral stress (load) acting on the not-shown linear guide rail (see reference numeral 121 in FIG. 8) is also substantially reduced by half to prevent the guide rail from being damaged. In other words, it is not necessary to secure sufficient strength of a linear guide roller (not shown in FIG. 8 at 119) and a linear guide rail (not shown) provided to prevent the chain 16 from being twisted, and the device (structure) is small and lightweight. This makes it possible to reduce costs. In addition, a smooth operation can be expected by preventing the cage 18 from being displaced by reducing the bending deformation of the chain 16. In addition, two outriggers 17b
It is obvious that the upper outrigger 17b has the same action as the above-described outrigger 17b when the upper sprocket 13 is positioned lower by circulating the upper sprocket 13 to the opposite side.

When the automobile A is parked in the above-described vertical circulation parking apparatus of the present embodiment, as shown in FIG. 3, the car A parked at a lowermost position through a storage gate (not shown). After entering the vehicle 18 and activating the side brake or the like to maintain the stopped state, the driver descends from the vehicle A. When the parking lot manager operates the operation panel (not shown) to drive the driving device 14 (hydraulic cylinders 24 and 25), the driving force rotates the upper sprocket 13 and causes the upper sprocket 13 and the lower sprocket 15 to move between the upper sprocket 13 and the lower sprocket 15. The looped chain 16 moves. Then, while each cage 18 attached to the chain 16 via the attachment 17 circulates vertically and moves to a predetermined position, the empty cage 18 stops moving to the lowermost position,
Next, it waits for the car A to park.
