[Industrial applications]

 TECHNICAL FIELD The present application relates to a safety belt for fall prevention used when working at a high place, and particularly to improvement of a belt-type safety belt that replaces a conventional rope.

[0002]

[Prior art]

 Conventionally used wind-up type safety belts have a shock absorber 9 between the winder 8 and the body tightening belt 4. In the belt winding method, unlike the rope, the expansion rate of the locking belt 6 itself, which is wound and stored in the winder 8, is low, the drop impact load is not easily buffered, and the operator's body is seriously damaged. A shock absorber 9 is provided to alleviate this. There is also one in which a shock absorber 9 is provided at the binding portion of the hook 5 and the fastening belt 6, but this is manufactured by overlapping a part of the fastening belt 6 and sewing multiple stitches to cover the capsule. Although it is made less bulky by continuously installing it, the shock absorber 9 does not work because the function is insufficient, and the shock absorber 9 does not work if it falls in the way of the structure of the tie belt. Even from the above, it was best to install it on the waist belt 4 side.

[0003]

[Problems to be solved by the device]

 However, when the conventional safety belt as shown in FIG. 9 was attached to the waist of the worker, the shock absorber 9 was not easy to fit in the curve of the waist, and there was not a little discomfort. Moreover, it was necessary to secure a space for inserting the tool bag or the like into the body fastening belt 4.

[0004]

[Means for Solving the Problems]

 Therefore, according to the present application, the shock absorber 9 is housed in the case 81 of the winder 8 so as to be located between the winder 8 and the belt 4 so as to conform to the curve of the waist and secure the space for the belt. To do.

[0005]

【Example】

 According to the embodiment of the present application, a buckle 2 is sewn on one end of a narrow woven belt 1, and a tip stopper metal fitting 3 formed by bending a thin plate into a U shape is crimped on the other end of the narrow woven belt 1 And a hooking belt 6 which is sewn with a hook 5 at the tip and is wound and stored from the base end portion by the biasing of a spring 7, and is passed through the body tightening belt 4. In a fall prevention safety belt 10 provided with a shock absorber 9 between the winder 8 and the body tightening belt 4, the shock absorber 9 is housed in the case 81 of the winder 8.

In the first embodiment, as shown in FIGS. 2 and 3, the shock absorbing portion 91 of the shock absorber 9 is folded and housed in the case 81 on the back side of the winder, and the portion connected to the body tightening belt 4 is the case 81. This is a sewn-out ring 92 that is sewn to the outside. Since there is no other cushioning part 9 compared to the conventional product, the length is shortened, and a space for suspending the body fastening belt 4 such as a tool bag is secured.

In the second embodiment, as shown in FIG. 5 to FIG. 8, the shock absorbing portion 91 of the shock absorber 9 is folded and housed in the case 81 on the back side of the winder, and the connecting portion to the body tightening belt 4 is also included. , It is sewn to a ring 92 that is integrated with the case 81, and all are stored in the case 81.As compared with conventional products, the number of insertions to the body tightening belt 4 is less and the assembly process can be omitted. Further, only the winder 8 projects from the body tightening belt 4, so that a space for hanging a tool bag or the like can be secured.

In the dropped state of the first embodiment, as shown in FIG. 4, the worker falls, the locking belt 6 is pulled out, and then the belt insertion portion 82 on the back side of the winder 8 case 81 is broken. The cushioning portion 91 of the shock absorber 9 is pulled out from the body tightening belt 4, and the entangled yarn of the superposed belt of the cushioning portion 91 is dissociated to alleviate the drop impact load. The fall state of the second embodiment is almost the same as that of the first embodiment, except that the part between the winder 8 part and the shock absorber storage case 81 on the back side of the winder is disengaged.

[0009]

[Effect of device]

 As described above, by using the fall-prevention safety belt to which the rope winder of the present invention is attached, since it is about the size of the winder, it can be attached to the waist exactly, and there is no discomfort when attached. In addition, since a space for inserting a tool bag, pliers insert, etc. can be secured, it is possible to attach tools suitable for the work to the waist, and there is a practical effect such that the work efficiency can be improved.
