Description of the Related Art Conventionally, a pair of inner and outer dedicated rails each consisting of a vertical portion and a horizontal portion and an arc portion connecting them, and an arm for a lower wheel and an upper wheel respectively traveling on the pair of inner and outer dedicated rails. A vehicle is mounted on this traveling floor that is fixed to an arm and projects to the front of the device, and the traveling floor is temporarily lifted vertically by a hoist to a predetermined height, and then inside and outside. A multi-stage parking device is known in which the traveling floor is pulled horizontally by keeping the traveling floor horizontal by the movement of the lower wheel and the upper wheel guided by each pair of dedicated rails. .

[0003]

However, in the above-mentioned conventional example, in order to support the protruding traveling floor, it is necessary to dispose the center of the upper wheel at a position separated from the traveling floor by about 500 mm from the center of the lower wheel. The total floor width of the pallet including the running floor intended for accommodating a vehicle with a width of 1700 mm, the arms fixed to it, and the upper wheels reaches 2700 mm, which increases the required area of the multi-stage parking system, resulting in poor land efficiency. There was a drawback.

The multi-stage parking system of the present invention is intended to solve the drawbacks of the multi-stage parking system of the conventional example described above. In the final retracted position (storage position) of the pallet, the center of the upper wheel is the center of the lower wheel. It is intended to provide a multi-tiered parking system in which the land efficiency is remarkably improved by bringing the same level as that of the above-mentioned point to the running floor.

[0005]

That is, a multi-stage parking apparatus according to the present invention is provided with a pair of inner rails for lower wheels, which are composed of a vertical portion and a horizontal portion, and an arc portion connecting the vertical portion and the horizontal portion, and a vertical portion and a horizontal portion. A pair of outer rails for exclusive use of upper wheels composed of an arc portion connecting the two are provided, and a pair of arms connecting the lower wheels and the upper wheels respectively traveling on the pair of inner and outer dedicated rails, and this arm. Has a pair of support beams that rotatably hold the vehicle and support the traveling floor in a state in which the rotation angle is limited by a stopper, and the vehicle is mounted on the traveling floor of the vehicle protruding to the front of the device. Is lifted vertically by a hoist to a predetermined height, and then the running floor is kept horizontal while the running floor is kept horizontal by the movement of the lower and upper wheels guided by the pair of inner and outer dedicated rails. In a multi-stage parking device configured to be pulled up, the lower surface of the support beam is supported by the receiving wheels provided on the front surface of the device in the vicinity of the horizontal part, so that the running floor is stable even when there is no upper wheel when the running floor is pushed horizontally. In this state, the wheel escape portion of the horizontal portion is guided to the exclusive rail of the upper wheel to guide the arm to rotate away from the stopper of the support beam so that the upper wheel approaches the running floor. By providing it on the back side, the depth dimension of the multistage parking device is made as close as possible to the width dimension of the automobile.

[0006]

According to the multistage parking apparatus of the present invention, the traveling floor,
The width of the entire pallet consisting of support beams, arms, upper wheels, lower wheels, etc. can be reduced when horizontal pulling is completed, and can be increased when the traveling floor is lowered to the ground. Is not only economical because it can be made small, but also when loading and unloading the vehicle by self-propelling, it is possible to increase the clearance between the rail surface and the vehicle, which facilitates the work.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the multistage parking apparatus of the present invention will be described below with reference to the drawings.

1 to 4 illustrate one embodiment of the multistage parking apparatus of the present invention.

In FIG. 1 and FIG. 2, reference numeral 1 denotes an automobile which is self-propelled to the running floor 2 and then pulled up and pulled together with the running floor 2 to be in this position. This position is the storage position where the automobile 1 and the running floor 2 are most pulled.

The running floor 2 is fixed to the support beams 3 on both sides. The support beam 3 is supported by a receiving wheel 6 attached to a dedicated outer rail vertical portion 12 of an upper wheel 4 and a lower wheel 5 sharing a shaft 7 with an arm 8. Since the lower wheel 5 is supported by the horizontal portion 11 of the dedicated inner rail, the automobile 1 is stable together with the running floor 2. The hoist 16 prevents the support beam 3 from moving horizontally via the chain 15.

At this time, the upper wheel 4 is guided into the wheel escape portion 14 of the outer rail and is closest to the traveling floor 2, and the arm 8 rotates counterclockwise to move away from the stopper 9 so that the arm 8 and The load supporting stress does not act on the wheel 4.
In this state, the pallet has the smallest width.

In order to lower the vehicle 1 in the stored state to the ground, the chain 15 is unwound by the hoist 16 suspended on the column 17, and the vehicle 1, the running floor 2 and the support beam 3 are moved leftward in the figure. However, this movement is stable and economical according to the method of the invention of Japanese Patent Application No. 4-41816 proposed by the present inventors.

That is, a slide shaft 21 is arranged along the horizontal portion 11 of the inner rail, and a piece member 22 that slides horizontally is mounted on the slide shaft 21. The piece member 22 is a protrusion 2 that is provided vertically below the support beam 3.
It is adapted to move by engaging with 3.

A wire rope 25 is connected to a fulcrum 24 of the piece member 22, and the other end of the wire rope 25 is connected to a counterweight 29 via sheeps 26, 27 and 28.

Therefore, in the state where the counterweight 29 is pulled up, the piece material 22 causes the projections 23 of the support beam 3 to be caused by the weight thereof.
Is pushed to the left, while the chain 15 connected to the support beam 3 is wound around the hoist 16, so that the vehicle 1 and the running floor 2 on which the vehicle 1 is mounted are at the positions shown in the figure. stable.

Of course, to lower the car 1 to the ground,
When the chain 15 is loosened by the hoist 16, the piece member 22 pushes the protrusion 23 of the support beam 3 to the left by the weight of the counterweight 29 by the amount of the looseness, so that the automobile 1 and the running floor 2 on which the automobile 1 is mounted are parked. Extruded on the front of the device.

As the vehicle 1, the running floor 2, and the support beam 3 move leftward in the figure, the upper wheel 4 is pulled out from the wheel escape portion 14 of the outer rail to reach the horizontal portion 13 of the outer rail, and at the same time, the arm. The tip of 8 hits the stopper 9. This state is shown in FIG.

Further, the car 1, the running floor 2, and the support beams 3 are pushed out, and eventually the upper wheel 4 is moved to the vertical portion 12 of the outer rail.
FIG. 3 shows a state in which the lower wheels 5 are supported by the vertical portions 10 of the inner rails.

In the state of FIG. 3, the support beam 3 for supporting the weight of the automobile 1 and the running floor 2 has a lower wheel 5 and an arm 8 by means of a shaft 7.
Although it is rotatably connected to the support beam 3, since the tip of the arm 8 contacts the stopper 9 of the support beam 3, the support beam 3 and the arm 8 do not rotate from the state of FIG. 3 depending on the weight to be supported.
The lower wheel 5 and the upper wheel 4 are attached to the arm 8. The lower wheel 5 is supported by the vertical portion 10 of the inner rail, and the upper wheel 4 is supported by the vertical portion 12 of the outer rail. The entire rotation moment of the traveling floor 2, the support beam 3, the arm 8 and the like is supported by the horizontal reaction force from the vertical portion 10 of the inner rail and the vertical portion 12 of the outer rail.

The vertical load is transmitted by the chain 15 to the hoist 16 via the chain wheels 18 and 19 and is supported by the column 17.

As the arm 8 is rotated by the shaft 7 as described above, the width of the entire pallet constituted by the traveling floor 2, the support beam 3, the arm 8, the upper wheel 4, the lower wheel 5 and the like is shown in FIG. Since the state of FIG. 1 is significantly smaller than the state of FIG. 4, the size of the multi-stage parking apparatus can be reduced and the site efficiency can be improved.

[0022]

According to the multi-stage parking apparatus of the present invention, the width of the entire pallet composed of the traveling floor, the support beams, the arms, the upper wheels, the lower wheels, etc. can be adjusted in the vertical and horizontal directions. In the retracted position, the upper wheel is guided to the wheel escape portion of the outer rail to rotate the arm so that it can be made significantly smaller than when moving.
The required area as a multi-stage parking system is reduced, and the land efficiency is significantly improved.
