BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a framed pallet used for storing and transporting luggage.

[0002]

2. Description of the Related Art Conventionally, a pallet with a frame in which a frame is attached around the upper surface of the pallet has been proposed.
The frame is composed of side panels and double doors, and has a rectangular frame shape. The side surface member is formed in a flat plate shape, and a pair of side surface members is erected on the upper surface side end portion of the pallet so as to face each other. The double door is composed of a pair of doors, and the double doors are arranged between the front and rear facing end portions of the side member, and each door of the double door is pivotally attached to the end portion of the adjacent side member. There is. The double door is provided with a locking tool formed of a horizontal rail and a rail receiver. The horizontal rail is formed in a rectangular shape which is long in the lateral direction, and is attached to the outer surface of one of the double doors so as to be vertically slidable, and the tip of the horizontal rail is projected toward the other door. The crosspiece receiver is formed by providing a concave groove that opens on the upper surface and both side surfaces, and is provided at the end of the other door of the double door. By loading luggage on the upper surface of the pallet in the frame, sliding the horizontal rail downward with the double doors closed, and inserting and locking the tip of the horizontal rail into the groove of the rail receiver. The double doors were locked and transported by lifts or stored as they were.

However, in the above-mentioned conventional example, when the load loaded on the pallet collapses and a large force is applied to the double doors from the inside, the horizontal bar slides upward by the urge to move horizontally. The tip of the crosspiece may slip out of the groove in the crosspiece, or pressure may be applied to the double doors from the inside to deform the horizontal crosspiece and crosspiece, causing the tip of the horizontal crosspiece to slip out of the groove in the crosspiece. Therefore, there is a risk that the horizontal rail and the rail receiver will be unlocked and the double door will open.

The present invention has been made in view of the above points, and an object of the present invention is to provide a pallet with a frame in which the double doors do not open even if the load loaded on the pallet collapses. It is a thing.
