Description

  The present invention relates to a load-unloading cart net for transported goods, for example, by attaching a side surface net of various transported items stacked in a stacked manner on a cart for cargo handling so as to prevent the cart from being unloaded. . The present invention relates to a belt for preventing collapse of luggage on a carriage. Specifically, it has a sufficient strength and elasticity that can prevent collapse of the luggage and a stretchable portion that facilitates operation. The present invention relates to a load preventing net for a bogie having a mounting portion in contact with the hook-and-loop fastener portion.

  Cardboard boxes, cases, and other items that are packed with various foods, products, products, etc. are transported and stored together in a stacked manner on a loading platform such as a cargo cart. By moving from one stand to another, storage in the warehouse is performed. In order to prevent the load of the transported goods loaded on the loading table from being unloaded during these movements and unloading, for example, the load unloading of the transported goods described in Japanese Patent No. 2605221 (Japanese Patent Laid-Open No. 7-149364). There is a prevention device.

  In the past, the loaded luggage was wrapped and fixed with wrap film (also called stretch film). This method takes a lot of time to wrap the wrap film, is covered with a wrap film when the luggage is refrigerated or frozen, and has a low cooling efficiency because it is hard to cool, and the wrap film after use However, there is a big problem in the environment, such as the fact that it can't be reused and disposal takes a lot of time and money.

For this reason, in recent years, a belt for preventing load collapse has been proposed that can be used repeatedly and does not require time and effort for disposal (see Patent Document 2).
Resin-made and wooden pallets are mainly used as a platform for loading luggage for loading / unloading of luggage into / from the truck's cargo room and loading / unloading of cargo into / from the management warehouse, freezer compartment, and the like. A part or all of the luggage is fixed to each other so that the luggage placed on the pallet and the carriage does not collapse and further does not protrude. The belt body which enabled the confirmation of the content was proposed (refer patent documents 1-2).

  There are few proposals for methods to prevent overhang and fall when loading cargo onto a cart with a fall prevention frame. In addition, the use of a net has been proposed for preventing collapse of luggage on pallets and carts (see Patent Documents 3 to 5). However, the connection of the nets is complicated, and a large area net is used, so that there is a problem in storage after use. There is a demand for a load collapse prevention net that can be easily connected to a net, has a small area, and is easy to store.
