Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a synthetic resin integrally molded pallet that can be suitably used for transporting various articles.

[Conventional technology]

Synthetic resin pallets have been known for some time.However, conventional plastic pallets are difficult to insert and remove the fork of the hand lifter into and out of the fork insertion hole, and articles wrapped in paper bags are placed on the synthetic resin pallet in multiple stages. The narrow width provided along the side edge of the connecting portion that connects the cylindrical girder at the corner and the cylindrical girder at the intermediate portion formed on the back surface of the synthetic resin pallet located at the top when stacked There was a drawback that the paper bag was easily broken when the machine came into contact with the paper bag of the article located at the lower stage.

[Problems to be solved by the invention]

The present inventors have made it easy for the fork of the hand lifter to be put in and taken out of the fork insertion hole. As a result of research on pallets, we arrived at the present invention.

[Means for solving the problem]

The present invention has a front part and a back part, and the front part and the back part connect the corner parts of the front part and the back part to each other.
It is connected by the cylindrical girder of the middle part connecting the middle part of the periphery of the front part and the back part and the center part of the girder connecting the center part of the front part and the back part, and between the cylindrical girder. In a synthetic resin integrated pallet in which a fork insertion hole is formed in a well-shape, a connecting portion for connecting a corner cylindrical girder and an intermediate cylindrical girder is formed on a surface portion, and the connection is formed. A crosspiece that crosses vertically and horizontally is formed on almost the entire surface of the part, and a connecting part that connects the cylindrical girder of the corner and the cylindrical girder of the middle part is formed on the back part, and the connecting part is formed in the center thereof. An upper plate-like portion at a position higher than the lower end of the girder is formed, and a lower plate-like portion whose lower surface is flush with the lower end of the tubular girder along both side edges thereof; Characterized in that a plurality of inclined ribs descending toward the edge of the lower plate-shaped portion are formed on the shaped portion. It relates butter made integrally molded pallet.
