Abstract

(57) [Abstract] [Purpose] To provide a tool for preventing collapse of a load by absorbing the looseness of a rope by utilizing a repulsive force of a spring, and which can be attached by a simple operation. [Structure] An upper spring receiver (1) and a lower spring receiver (3) are provided above and below the spring (2), and the springs are compressed by pulling each other, and the looseness of the rope is absorbed by the restoring force of the springs. And

Description

[Detailed description of the invention]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a load collapse prevention tool for preventing loosening of a rope attached to a rope for carrying a load on a truck or the like by utilizing the repulsive force of a spring.

[Prior Art] Conventionally, the only method of preventing load collapse is to rely on a tightening force using a multiple pulley method using a rope.

[Problems to be Solved by the Invention] This has the following drawbacks. (B) When the loaded truck recoiled due to uneven roads or curves, there was looseness in the rope due to the movement of the load. (B) The looseness of the rope caused the load to rattle or drop. (C) When the looseness of the rope became large, the rope could come off the hook of the loading platform and cause the load to collapse.

[Means for Solving the Problem] A spring receiver (lower) (3) is hung on a hook of a loading platform, and a spring receiver (upper) (1) is tied to a rope end to tie a load to compress the spring. Then, the looseness of the rope due to the collapse of the load is absorbed by the reaction force of the spring.

[Operation] The spring (2) is mutually pulled by the spring receiver (upper) (1) and the spring receiver (lower) (3) to be compressed, and the looseness of the rope can be absorbed by the restoring force of the spring. it can.

Hereinafter, an embodiment of the present invention will be described. Since the tip of the spring receiver (lower) (3) is slightly bent, it can be hooked directly on the hook of the cargo bed. Since the tip of the spring receiver (upper) (1) is bent in a U shape, it can be used as a hook and the rope can be pulled easily. Attach the load collapse prevention device to the truck bed hook and use it as one end of the rope to bind the load.

[Advantage of the Invention] It is possible to prevent the rope from loosening due to the collapse of the load of the truck. Even for loads such as home appliances that cannot be bound tightly in cardboard boxes, the reaction force of the spring can prevent the rope from loosening due to the collapse of the load. It can be used not only to prevent the cargo from collapsing but also to prevent loosening of all ropes.
