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] The storage part 4 is formed by forming a hooked tip end that tapers in sequence and bulging to one side between a continuous base end part 2 and a continuous end part 3.
The two seats have the same shape, and two hook bodies 5 of the same shape but with different bulging directions are overlapped and fixed so that the space of the storage part 4 is continuous. Is connected to one end of the shock absorber 7, which is made by stacking a narrow belt in the length direction and sewn in multiple directions, and is placed in the storage part 4 and taken out from the base end 3 and the hook part 1 of the storage part 4 is connected. An opening / closing cap 8 is attached to the inner surface to abut on the tip of the hook 1.
A safety cap 9 is provided on the outer side surface of the shaft 4 so as to come into contact with the opening / closing cap 8 and control its rotation. [Effect] Since the shock absorber is housed in the hook body, it does not interfere with the work and can prevent strength deterioration due to ultraviolet rays.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present application relates to a hook of a safety belt used when working at height, and more particularly to a hook having a shock absorber integrally with a hook main body that absorbs a shock when a fall occurs.

[0002]

[Prior Art and Problems]

 As shown in Figs. 3, 4 and 5, the safety belt for work at high places that has been conventionally used is that a rope or an alternative belt R is connected to a belt B worn on the waist of an operator, and a hook F is attached to the tip thereof. The shock absorber S for the purpose of mitigating 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. It is a shock absorber that has a certain amount of texture and texture when locking the hook and during the work after locking, as the hook is repeatedly hanged when moving to the work place when using the safety belt. It was uncomfortable and uncomfortable for the worker to swing the hip at the waist or at the root of the hook. Also, shock absorbers are generally manufactured by sewing belts, and although they are covered with vinyl leather, it is not desirable to expose them in the middle of the rope in terms of weather resistance. It was

[Means for Solving the Problems]

 In order to solve the above problems, the present application discloses a technique of integrating a shock absorber with a hook. The minimum requirement for the structure of the safety belt hook is to have an opening / closing cap whose rotation is controlled by the safety cap and a space for the hook portion, which is composed of a hook-shaped portion. It was good to say that it is only an extension of the ridge, and it only plays a role in obtaining the location of the shaft fulcrum of each cap and the location of the binding portion of the rope. Therefore, the shock absorber is built into this main body and is integrally configured to solve the problem. Specifically, the problem is solved by superposing two hook-shaped hook bodies and connecting and storing a shock absorber in the space formed at the base end of the hook bodies.

【Example】

 According to one embodiment of the present application, a plate-like member is formed with a tapered front end in the shape of a hook, and a storage part 4 is provided which bulges to one side between a starting end 2 and a terminal end 3 of a base end part which is continuous with it. . In addition, another hook main body having the same shape but having a different bulging direction of the storage portion is prepared, and the two bulging portions of the hook main bodies 5 are overlapped to form a continuous storage space. At the time of this stacking, a mounting seat 6 is sandwiched at the base end of the storage part, and a shock absorber 7 is connected to the mounting seat 6 and stored in the storage part 4. The shock absorber 7 is a narrow woven belt that is overlapped in the length direction and is sewn with multiple threads to a specified strength.When a shock load is applied to both ends, the sewing thread in the overlapping part is dissociated. , To alleviate the impact. The other end of the shock absorber 7 is taken out from the end of the hook body 5 which is the end of the storage part 4 and extends so as to be connected to the belt of the safety belt. The hook main body 5 made of two plate members is superposed and fixed by a rivet 51 at a predetermined position. On the inner surface of the hook part 1 of the storage part 4, an opening / closing cap 8 that comes into contact with the tip of the hook part 1 from the inside is provided with a spring to pivotally support it. On the outer surface, a safety cap 9 that contacts the opening / closing cap 8 and controls its rotation is axially supported by a spring.

[0005]

[Effect of device]

 As described above, by storing the shock absorber in the main body of the hook, the handleability during work is improved. In other words, by connecting the shock absorber that was connected to the base end of the hook or connected to the rope attachment part of the belt to the hook itself in the past, the hook becomes loose and the waist becomes bulky when the hook is operated. It is something that disappears. Also, shock absorbers, which are mainly made of synthetic fibers, are subject to strength deterioration due to ultraviolet rays, but this problem can be solved by housing them in a metal housing.
