Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus and a device for winding up a wire member for a carrier, which is suitable for carrying a load on a carrier.

[0002]

Conventionally, when carrying a load on a carrier, for example, a pallet or a trolley, the collapse of the load is carried out by binding the load with a long linear member such as a band or a string. I was trying to prevent it.

[0003] However, in such a device, there is a problem that it is necessary to prepare a packing linear member separately from the bed, and it is troublesome to connect the linear members.

As a countermeasure against such a problem, there is known one disclosed in Japanese Utility Model Laid-Open No. 6-6236 (Japanese Patent Application No. 4-51658). This has a structure as shown in FIGS. 18 and 19. That is, the belt winding device 5 including the belt winder 4 that winds the belt 3 that is the linear member for packing is attached to the bottom surface of the underframe 2 of the carriage 1 that is one of the loading platforms. . The base 6 of the belt winding device 5 is provided with a foot lever 7 at a position apart from the belt winder 4, and a tightening mechanism 9 including the foot lever 7 and a buckle 8 is provided. It is provided.

In the case of the above construction, the belt 3 is pulled out from the belt winder 4 and is hung on the luggage, and the foot lever 7 is operated while the hook 3a at the tip of the belt 3 is hooked on the foot lever 7. By tightening the belt 3 by the tightening mechanism 9, the baggage is bound by the belt 3 and the belt 3 is locked so as not to be loosened.

According to such a structure, it is not necessary to prepare the belt 3 for packing separately from the carriage 1, and
The belt 3 can be easily tightened. However, in the above-mentioned configuration, since the foot lever 7 is provided at a position distant from the belt winder 4, the base 6 and the entire apparatus become large, and it is difficult to reduce the size. Further, since the tightening mechanism 9 has a structure in which the belt 3 itself is tightened by the buckle 8, there is a drawback that the belt 3 is easily damaged.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a load-carrying linear member winding device and a cargo carrier which can be downsized and can lock a packing linear member without damaging it. .

[0008]

In order to achieve the above-mentioned object, the linear member winding device for a cargo bed of the present invention has a frame attached to the cargo bed and a winding body rotatably provided on the frame. And a long linear member wound around the winding body so as to be able to be drawn out and having a hooking portion at its tip, and a rotational force in the winding direction of the linear member is always applied to the winding body. A mainspring provided as described above, an operation lever provided on the frame in the vicinity of the winding body so as to be operable from the outside, and the winding body which is operated by moving the operation lever to a lock position. The present invention is characterized in that it is provided with a lock mechanism for locking the rotation of the paper in the winding direction and the drawing direction.

According to this structure, since the operation lever for locking the loosening of the linear member is provided in the vicinity of the winding body for winding the linear member, the size of the entire apparatus can be reduced. be able to. Further, since the lock mechanism that locks the looseness of the linear member is configured to lock the rotation of the winding body, the linear member can be locked without damaging the linear member.
