[0002]

2. Description of the Related Art Conventionally, as a vertical circulation type multi-story parking device,
JP-B-63-19663 and Jitsuhei 3-30511
The three-dimensional parking device of this type is well-known, and this type of multi-story parking device is suspended at predetermined intervals on an endless chain rotatably provided between upper and lower positions, and vertically suspended by rotation of the endless chain. The vehicle includes a plurality of vehicle-mounted cages circulating in the direction, and a vehicle-mounted pallet mounted on each of the cages. In addition, the multi-story parking device includes an elevating and turning device that lifts a pallet on which a vehicle is mounted on a cage facing the vehicle entrance and turns the vehicle in a predetermined direction to change the direction of the vehicle when the vehicle enters or leaves the vehicle. .

Each of the cages includes a cage stay extending in the front-rear direction of the mounted vehicle and having both ends rotatably connected to the endless chain, a pair of front and rear hangers connected to both ends of the cage stay and extending downward, And a rectangular frame-shaped pallet table connected to the lower ends of both hangers for mounting the pallet. At the center of the frame member located at both ends in the vehicle front-rear direction of the pallet table, a convex portion bent upward is formed, and a concave space below the convex portion allows a cage stay of a cage adjacent to the cage below. And avoid contact with it.

On the other hand, the pallet is provided with a pair of vehicle entrance portions extending in the vehicle front-rear direction on which the wheels of the vehicle ride, and between the vehicle entrance portions so as to correspond to the projections of the pallet table. A convex portion protruding upward from both vehicle entrance portions is formed.

When the pallet is swiveled, the lifting and lowering swivel device raises the pallet above the pallet base so as to prevent the pallet from contacting with the pallet base. After being lifted, it is turned.

However, in the above-mentioned conventional multi-story parking device, the lift amount by which the lifting / lowering turning device lifts the pallet is:
It is a large amount that adds a certain margin to the height of the projection of the pallet table. Therefore, it is necessary to provide a space above the vehicle upper end and the cage stay to avoid contact between the upper end of the vehicle and the cage stay when the vehicle is lifted, by the height of the convex portion. There is a problem that the height is increased and the height of the entire apparatus is increased.

Therefore, the present applicant reduces the length of the pallet in the longitudinal direction of the vehicle so that the pallet does not come into contact with the convex portion of the pallet table when the pallet is lifted and turned, thereby reducing the lift amount of the pallet. A multi-story parking device in which the height of the cage is reduced and the height of the entire device is reduced has been previously filed (see the specification and drawings of Japanese Patent Application No. 4-135228).

[0008]

However, when the length of the pallet in the longitudinal direction of the vehicle is shortened as described above, a gap is formed between the pallet and the convex portion of the pallet table. Problem of giving the user a dirty feeling or a fear.

Another problem is that dust and engine oil fall from the vehicle mounted on the upper cage during vertical circulation and adhere to the vehicle mounted on the lower cage.

[0010] The present invention has been made in view of the above points, and an object of the present invention is to reduce the height of each cage as described above to reduce the height of the entire parking device, and to reduce the height of the pallet. By improving the shape of the protruding part, it covers the gap with the pallet table, so that the inside of the pit is not visible so that the user does not feel dirty or fear, and the fall of dust and engine oil etc. Eliminating the dirt on the vehicle.

[0011]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention is directed to an endless chain rotatably provided between upper and lower positions and suspended at predetermined intervals by a rotation of the endless chain in a vertical direction. A plurality of circulating vehicle-mounted cages, a pallet mounted on each of the cages and on which a vehicle is mounted, and a lifting and lowering turning device for lifting the on-board pallet on the cage facing the vehicle entrance and turning in a predetermined direction, Each cage includes a cage stay extending in the front-rear direction of the mounted vehicle and having both ends rotatably connected to the endless chain; a pair of front and rear hangers connected to both ends of the cage stay and extending downward; A rectangular frame-shaped pallet table which is connected to the lower end of the pallet and on which the pallet is placed. While the convex portion is bent upwardly so as not to contact the cage stay cage is formed,
The pallet has a pair of vehicle entry portions extending in the vehicle front-rear direction on which the wheels of the vehicle are mounted, and is located between the two vehicle entry portions so as to correspond to the convex portion of the pallet table and is located above the vehicle entry portions. The following solution was taken for a vertical circulation type multi-story parking device in which a protruding portion is formed.

That is, a solution of the present invention is to provide a predetermined gap in the vehicle longitudinal direction between the pallet and the convex portion of the frame member so as not to come into contact with the convex portion of the frame member when lifting and turning the pallet. Is formed to a length at which Further, extending portions are formed at both ends in the vehicle front-rear direction of the protrusions of the pallet, the protrusions facing above the protrusions of the frame member. Further, the invention is characterized in that both vehicle entry portions of the pallet are positioned below the upper surface of the convex portion of the frame member when the pallet is lifted and turned.

[0013]

With the above arrangement, according to the present invention, when the pallet on which the vehicle is loaded at the time of loading and unloading is turned up in the predetermined direction by being lifted by the elevating and turning device, both vehicle entry portions are raised on the upper surface of the projection of the frame member of the pallet base. In a state of being located further below, the vehicle turns without contacting the projections of the pallet table due to the gaps provided between both ends of the vehicle entrances in the vehicle longitudinal direction and the projections of the pallet table.

Therefore, there is no need to raise the pallet to a height that avoids contact with the projection of the pallet stand,
The vehicle can be turned while being slightly lifted from the pallet table, so that the gap between the upper end of the vehicle on the pallet and the cage stay can be designed to be small, and the height of each cage can be reduced. In addition, when the cage circulates due to the rotation of the endless chain, the upper cage is prevented from contacting with the cage stay of the lower cage due to the concave space formed below the projection of the pallet table, The arrangement pitch between adjacent cages is reduced by the height of the concave space.

Further, above the convex portion of the pallet table,
Since the extending portions formed at both ends in the vehicle front-rear direction of the convex portion of the pallet face, the extended portion covers the convex portion of the pallet table from above, and the inside of the pit can be seen from between the two. It does not give the user a dirty or fearful feeling.

Further, dust, engine oil, and the like that fall from the vehicle mounted on the upper cage during vertical circulation do not adhere to the vehicle mounted on the lower cage because they are blocked by the extension.
