Description of the Related Art As shown in FIGS. 9, 10 and 11, a safety belt for work at high places which has been conventionally used has a rope B or a belt R instead of the rope as a belt B wound around the waist of an operator. It is connected and the hook F is connected to the tip thereof. The shock absorber S for the purpose of mitigating the impact load when the fall occurs and the fall is stopped is interposed between the belt B and the rope R or between the rope R and the hook F. When working with a safety belt,
Although the hooks are often re-hooked when moving from place to place, the shock absorber with a certain amount of volume and texture feels bulky at the waist or sways at the base of the hook during and after locking. This was difficult and unpleasant for the operator. In addition, shock absorbers are generally manufactured by sewing synthetic fiber belts, and although they are covered with vinyl leather, etc., they are weather-resistant, and are not damaged by contact with sharp corners. Considering that, exposure was not desirable.

It is essential that the hook of the safety belt has a space for the hook portion, which is composed of an opening / closing cap controlled by the safety cap and the hook portion. The main body part, which is an extension of the hook-shaped part, requires a predetermined length to support both caps, but if this part is extended and hollowed and one end of the shock absorber is connected and housed, there is a problem. Can be solved.
In other words, one end of a shock absorber made by sewing a narrow woven belt is connected to the base end of the hook-shaped part, the sewing part is housed in a case that is also connected to the base end, and the shock absorber from the end of the case The other end is taken out and the belt is wound in the waist in a continuous narrow woven belt or connected to a rope and wound around the waist. With the above configuration, it is integrated with the hook and is compact, and because it is covered by the case, it has excellent weather resistance,
It is possible to obtain an integrated hook with a built-in shock absorber that is less likely to be damaged.

The opening / closing cap 3 contacts the tip of the hook-shaped portion 1 to form a space for the hook, and the safety cap 4 contacts the opening / closing cap 3 to control the rotation thereof. That is, the opening / closing cap 3 can be rotated by pressing the safety cap 4 against the spring with the shaft as a fulcrum. A mounting hole 7 is provided at the base end of the main body 2 and a shock absorber 6 is attached. The shock absorber 6 folds a narrow woven belt in the length direction for superposition and superimposes it. By dissociating, the impact force is alleviated. One of the tear ends of this shock absorber 6 is sewn to the mounting hole 7, and the other is connected to the connecting ring 8.
To join the sewing. The shock absorber 6 between the mounting hole 7 and the connecting ring 8 is housed in the case 5. The case 5 is in the form of a two-part box whose one end is fixed to the base end of the main body, and is fixed by a rivet 11. The connecting ring 8 is tied with a rope that connects between the waist belts. With the shock absorber integrated hook of the present application configured as described above, if a fall occurs during work using the safety belt, a drop impact load acts on the shock absorber 6 in the case 5 and the shock absorber 6 It acts as a tearing load, dissociates the sewing thread, and relaxes the impact force. As another embodiment, as shown in FIGS. 3 and 4, the base end portion of the main body is extended and bent in one direction in a crank shape so that the shock absorber 6 can be positioned on a line passing through the centers of the hook-shaped portion 1 and the cap. Then, the case 5 is provided by covering it from one side with a cap made of aluminum or the like. With such a structure, the main body becomes strong, and the case is less likely to be damaged even when a lateral load is applied to the hook. 5 and 6 show the third embodiment, in which the case 5 having a U-shaped cross section is connected to the main body, and the shock absorber 6 is rotatably attached to the base end portion of the main body by the attachment ring 9. Case
The shock absorber 6 can be inspected by storing it in the groove of 5 and using it, turning it and taking it out. The shock absorber 6 is covered with a transparent heat-shrinkable tube 12 so that the sewing thread can be visually inspected. Furthermore, the one shown in FIGS.
In addition to the third embodiment, a lid-like section having a U-shaped cross-section corresponding to the third embodiment is rotatably connected to the hook body base to add a second case 10. Is closed, and the second case 10 is rotated during inspection, and then the shock absorber 6 is rotated. In the embodiments 2, 3 and 4 described above, the other end of the shock absorber 6 extends continuously to the belt wound around the waist.

のである。The following effects can be obtained by using the present invention having the above-described structure. Since the shock absorber is integrally housed and provided in the main body of the hook, the belt wound around the waist is not bulky and does not swing at the root of the hook, thereby eliminating unpleasantness during work. Further, the shock absorber mainly made of synthetic fiber is weak against ultraviolet rays and causes strength deterioration, but the degree of deterioration can be reduced by housing it in a case continuous to the main body. Further, by housing the shock absorber in the case, it is possible to avoid the risk of unintentional contact with a sharp corner and being damaged during work.
