BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cargo movement prevention device, and more particularly, to an improvement of a cargo movement prevention device for preventing collapse of cargo stored and used, for example, in a truck bed or container. It is related to.

[0002]

2. Description of the Related Art In general, when loading cargo onto a truck bed or a ship, the cargo may collapse due to shaking during traveling or traveling, and it is necessary to prevent individual cargo from moving.

Therefore, conventionally, a cargo movement preventing device has been used in which a moving beam is erected on a pair of parallel guide rails provided along opposing side walls of a room for accommodating cargo to prevent the cargo from moving. (See Japanese Utility Model Application Laid-Open No. 61-80194).

In this type of cargo movement preventing device, a mounting hole is formed in the guide rail at an appropriate interval, and an engaging means having an engaging metal fitting which is removably engaged with the mounting hole is moved. A structure having a structure protruding slidably at both ends of a beam has also been proposed. According to this structure, there is an effect that a moving beam can be installed corresponding to a change in the interval between the guide rails in one type of moving beam.

[0005] In this kind of cargo movement prevention device configured as described above, one worker engages the ends of the moving beams with the guide rails and bridges them, so that the weight of the moving beams is reduced as much as possible. Therefore, it is necessary to reduce the weight, and therefore, the moving beam is formed of a hollow aluminum alloy extruded profile, and a steel member is used for the engaging means requiring strength.

[0006]

However, in this type of cargo movement preventing device of this type, a pair of steel members bent in a channel shape are back-to-back with engaging means, and fixing means such as rivets are used. In order to fix, a large number of constituent members are required, the number of processing steps is increased, and the weight of the engaging means is increased, and contrary to the reduction in the weight of the moving beam, the overall weight can be sufficiently reduced. There was no problem. In addition, since the engaging means has a structure for connecting the channel-shaped steel members, dust and the like may adhere to the connecting portion. In addition to the necessity, the sliding of the engagement means may be hindered by the attached dust.

The present invention has been made in view of the above circumstances, and provides an easy-to-handle cargo movement prevention device which can be formed with a small number of constituent members, reduces the number of processing steps, is lightweight and has excellent hygiene. The purpose is to do so.
