Therefore, the structure is complicated and large-scaled, and the manufacturing and mounting costs are high. Therefore, it is not a good idea to attach the three-tiered parking facility and the two-tiered parking facility, which are advantageous in that the overall facility cost is relatively low, from the viewpoint of restraining the facility cost.

In view of such conventional circumstances, the present invention provides a door protection device for a multi-tiered parking facility which has a simple structure, is easy to maintain and manage, and has improved safety with a small facility cost. It is in.

(Means for Solving the Problem) The door protection device for a multi-tiered parking facility of the present invention has a plurality of rows of transverse parking spaces and a plurality of rows of elevating and lowering parking spaces which are vertically formed in a plurality of stages. A traverse pallet and an evacuation space for laterally moving the traverse pallet are provided, and a hoisting and lowering parking space is provided with a hoisting and lowering pallet capable of raising and lowering with respect to the traverse parking space. In a multi-tiered parking facility in which a delivery opening is provided in the transverse parking space, reflectors attached to both ends of each of the traversing pallets and each elevating pallet, and a traversing pallet facing the entry / exit opening or To detect the open state of the car door on the lifting pallet,
A reflection type having an end portion on the opposite side of each pallet on which each reflection plate is provided so as to irradiate each reflection plate with light and capture the reflected light It is characterized in that it comprises a photocell, and an emergency stop relay is connected to the reflection type photocell so as to prevent the traversing pallet and the lifting pallet from being activated, thereby achieving the above object.

(Operation) The operation of the above means is that when the side door of the automobile located at the position directly facing the entry / exit port is left open, this side door causes the light flux of the reflection type photocell to pass through. When the relay is turned off and the emergency stop relay is excited, the driving means for the ascending / descending pallet and the traversing pallet cannot be activated. Here, when the side door is closed, the emergency stop relay is automatically demagnetized, and the driving means for the ascending / descending pallet and the traversing pallet can be activated.
