2. Description of the Related Art In such a multi-story parking garage, for example, four parallel sides of a pallet are mounted on a pallet in order to prevent the door of the vehicle from opening and interfering with other equipment in the multi-story parking garage during transportation of a pallet carrying a vehicle. A door opening prevention frame formed in a link shape is provided. When the vehicle enters or leaves the vehicle, the door opening prevention frame is released when a passenger gets on or off the vehicle on the pallet whose front and rear ends are in contact with the floor of the external communication portion, and From the point in time when the swivel platform raises the pallet to the ascending position in order to turn the pallet on which the vehicle is mounted or emptied, the pallet is in the blocking position. Conventionally, in order to switch this blocking position to the release position, a contact is made to push the door-opening blocking frame against the return side of the blocking position against the floor side of the external communication section, avoiding the swivel or the elevating section. It is considered to provide a part. As a result, the door opening prevention frame can be switched to the release position with a simple configuration that does not require special driving means.

[0003]

By the way, in order to ensure that the door opening prevention frame is in the blocking position from the time when the swivel base raises the pallet to the raised position as described above, the swivel base is positioned at the center in the front-rear direction of the pallet. In consideration of the fact that the pallet bends in an upwardly convex shape by receiving and supporting the pallet, it is necessary to raise the pallet to a height at which the door opening prevention frame is separated from the contact portion. However, in the above-described conventional configuration, since the contact portion is provided on the floor side of the external communication portion corresponding to a portion near the front and rear ends of the pallet, avoiding the swivel and the lifting / lowering portion, the contact portion corresponds to the contact portion. Considering that the deflection of the pallet at the location where the pallet is bent is larger than the deflection near the center of the pallet, the height at which the swivel base needs to raise the pallet is increased, and the swivel base is increased in size. was there. The present invention has been made in view of the above circumstances, and an object of the present invention is to reduce the height at which a swivel base needs to raise a pallet as low as possible.

[0004]

According to the present invention, there is provided a multi-story parking lot.

Therefore, the occupant of the vehicle can open the door and get off the vehicle. When the occupant gets off the vehicle, the turntable rises to the raised position with the pallet mounted. After this point, the contacted portion of the door opening prevention frame is separated from the contact portion of the elevator, and the door opening prevention frame is switched to the blocking posture. That is, the height of the ascending position is set to a height necessary for the contacted portion of the door opening prevention frame to be surely separated from the contacting portion of the elevating portion. After that, when the swivel table turns the pallet to the direction for elevating and lowering, the elevating unit moves up and the pallet is placed on the elevating unit. Then, the elevating unit conveys the pallets to empty shelves.

[0006] When the vehicle is to be taken out of the car, when the elevating unit lowers the pallet on which the vehicle is mounted to the external communication unit, the swivel at a predetermined ascending position receives and supports the central portion of the pallet in the front-rear direction. . Then, the swivel base rotates the pallet to the direction for getting on and off, and then descends to the lowering position, so that both front and rear ends of the pallet are in contact with the floor of the external communication portion. At this time, the contacted portion of the door opening prevention frame comes into contact with the contact portion of the elevating unit, and the door opening prevention frame that has been in the prevention position to prevent the vehicle from opening is switched to the release position. .
Thus, the door can be opened for the occupant to get into the vehicle.

As described above, the height of the raised position at which the swivel base raises the pallet is a height required for the contacted portion of the door opening prevention frame to be securely separated from the contact portion of the elevating portion. However, in the characteristic configuration of the present invention, since the contacting portion that contacts the contacted portion of the door opening prevention frame is provided in the elevating portion located near the center of the pallet, the pallet when the pallet is raised The height of the ascending position can be set with almost no influence of the deflection.

[0008]

According to the above configuration, the height of the raised position can be set with almost no influence of the deflection of the pallet when the pallet is raised, so that the height of the raised position is made as low as possible. And the turntable can be prevented from being enlarged.
