JP3006455U - Safety belt hook - Google Patents

Abstract

(57) [Summary] [Purpose] To obtain a safety belt hook with a built-in shock absorber that does not interfere with work and has excellent weather resistance. [Structure] A shock absorber 2 formed by bending and stacking a narrow width woven belt in the length direction at the base end of the hook-shaped portion 1 curved in a hook shape, and covering with a capsule 3 a shock absorber 2 formed by sewing multiple threads Connect one end of it to the body part 4 with a roughly U-shaped cross section that also houses the shock absorber 2 by connecting it to the base end of the hook part 1 as well.
An opening / closing cap 5 that abuts on the tip of the hook-shaped portion 1 to form a space for the hook, and a safety cap 6 that abuts on the opening / closing cap 5 and controls the rotation thereof are provided. [Effect] Since the shock absorber is housed in the main body having a U-shaped cross section, it does not interfere with work, has excellent weather resistance, and can be visually inspected.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present application relates to a safety belt hook used when working in high places, and more particularly to a hook having a built-in shock absorber that absorbs the impact when a fall occurs.

[0002]

[Prior Art and Problems]

 As shown in FIGS. 6, 7 and 8, a safety belt for work at high altitudes that has been conventionally used is to connect a rope or a belt R instead of a rope to a belt B wound around the waist of an operator and hook it at its tip. The shock absorber S, which is connected to the belt F and has the purpose of reducing the impact load at the time of dropping, is interposed between the belt B and the rope R or between the rope R and the hook F. When working with safety belts, the hooks are re-hooked many times when moving from place to place, and a shock absorber with a certain amount of texture and texture can be placed on the waist during locking and after work. Swinging at the root of the hook was uncomfortable and unpleasant for the operator. In addition, shock absorbers are generally manufactured by sewing a belt made of synthetic fiber, and although they are covered with vinyl leather, etc., they are not exposed in the middle of the rope due to weather resistance. It wasn't desirable.

[Means for Solving the Problems]

 In order to solve the above problems, in the present application, the shock absorber is housed in the hook. The minimum requirement for the structure of the safety belt is to have a space for the hook, which is composed of the opening / closing cap 5 and the hook 1 which are controlled by the safety cap 6, and the main body 4 has the hook 1 It was good to say that it only plays a role in obtaining the place to set the pivotal fulcrum of each cap and to obtain the place of the binding part of the rope or belt. Therefore, the problem is solved by making the main body part 4 also serve to house the shock absorber 2. Specifically, the hook-shaped part 1 was made short, and one end of the shock absorber 2 was connected to the connecting hole 11 provided at the base end thereof, and the shock absorber part was also connected to the base end of the hook-shaped part 1. It is housed in a main body 4 having a U-shaped cross section, and an opening / closing cap 5 and a safety cap 6 are axially supported on the main body 4 and springs are arranged. The belt 12 at the other end of the shock absorber 2 that extends from the end of the main body 4 continues to the belt at the waist. By adopting the above configuration, the shock absorber can be stored in the main body that pivotally supports the opening / closing cap and the safety cap, and by not providing it in an exposed position, the shock absorber mainly made of synthetic fiber naturally deteriorates due to sunlight. It is possible to prevent damage and to prevent damage caused by contact with sharp edges.

【Example】

 According to one embodiment of the present application, a long groove-shaped belt connecting hole 11 is provided at a base end portion, and a hook-shaped portion 1 is formed which is gradually curved toward the tip end. The belt connecting hole 11 has a structure in which narrow width woven belts are overlapped in the length direction, the overlapped portion is sewn multiple times a predetermined number of times, and the sewn portion is covered with a capsule made of a heat-shrinkable tube. Connect one end of shock absorber 2. The other end of the shock absorber 2 extends as it is to the safety belt. The capsule portion including the belt connecting hole 11 is housed in a molding material having a substantially U-shaped cross section. The U-shaped molding material is riveted to the hook-shaped part closer to the tip than the connecting hole, and the opening 10 is open toward the inside of the hook, and the opening / closing cap 5 is inside the hook and the safety cap 6 is outside. Is pivotally supported. The tip of the open / close cap 5 is in contact with the tip of the hook 1 and keeps the hook closed by a spring at all times.It engages the safety cap 6 at the base end and This closed state cannot be released unless the rotation of the. Although it is the first embodiment configured as described above, as another embodiment, as shown in FIGS. 4 and 5, it is possible to adopt a configuration in which the opening 10 is directed toward the back side of the hook as shown in FIGS. The inspection is easier and other effects are the same.

[Effect of device]

 By using the device of the present invention having the above-described structure, a hook with a shock absorber that does not interfere with work, has excellent weather resistance, and is less likely to be damaged can be obtained. In addition, by forming the main body into a U-shaped cross section, the shock absorber accommodated can be visually inspected, and since the main body is open, breathability is good and the shock absorber made of synthetic fiber can be used. The performance can be maintained. In the conventional safety belt, the shock absorber has been overlapped with the belt portion of the safety belt and connected, or it is interposed between the rope at the base end of the hook or the belt. Therefore, the waist is bulky and worrisome, and it is difficult to handle because it swings every time the hook is locked, and it is bulky when the hook is stored in a bag when walking without a safety belt. However, the problem is solved by storing them in the main body of the hook.
