JP3006813U - Safety belt hook - Google Patents

Abstract

(57) [Summary] [Purpose] To improve the handleability during work and prevent the strength of the shock absorber from being deteriorated by ultraviolet rays. [Structure] A shock absorber 5 is connected to the opening / closing cap 3 or safety cap 4 of the hook. [Effect] The handleability during work is improved, and since the shock absorber is housed in the cap, it is possible to prevent strength deterioration due to ultraviolet rays.

[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 shock absorber in a cap portion that absorbs a shock when a fall occurs.

[0002]

[Prior Art and Problems]

 As shown in FIGS. 7, 8 and 9, a safety belt for work at high places that has been conventionally used is to connect a rope or a rope-like belt R 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 relaxing the impact load when it is dropped, 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, the hooks are re-hooked over and over again when moving to a work place.The shock absorber has a certain amount of texture and texture during locking and after locking It was uncomfortable and unpleasant for the operator to swing the hips at the waist or at the base 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 part of the rope in terms of weather resistance. There wasn't.

[0003]

[Means for Solving the Problems]

 In order to solve the above problems, in the present application, the shock absorber is integrated with the hook. The minimum requirement for the structure of the safety belt hook is to have a space for the opening and closing cap controlled by the safety cap and the hook formed by the hook, and to configure the hook. The problem can be solved by providing a shock absorber integrally on either the main body or both caps, and the cap is selected in the present application. The opening and closing cap accommodates a shock absorber made by stacking multiple layers of belts and connecting the belt extending from the rear end of the hook to the safety belt. In the shock absorber connected to the tip of the opening / closing cap, the overlapped sewing part is dissociated by an impact load more than a predetermined value, and the belt part whose size is dissociated and extended extends from the base end of the opening / closing cap. It is a shock absorber. Further, the structure in which the shock absorber is housed in the safety cap is the second embodiment, and the effects are the same.

【Example】

 An example of the present application will be described. A hook body (2) having a smaller diameter and being bent into a hook shape is formed in order toward the tip. The opening / closing cap 3 is pivotally supported inside the base end of the main body 2. The opening / closing cap 3 has a substantially U-shaped cross section, and has an engaging portion 7 for engaging the shaft support 6 and the safety cap 4 at one end, and a mounting seat 8 for mounting the shock absorber 5 at the tip, engaging pin 9 Provided by. The engaging pin 9 provided at the tip engages with the hook-shaped portion 1 of the hook body 2 and the engaging portion 10 at the tip, and when the load is applied to the hook-shaped portion 1, the engagement between them is easily released. Will not be opened. The safety cap 4 pivotally supported on the outside of the base end of the main body 2 controls the rotation of the opening / closing cap 3. It is necessary to disengage from. To a mounting seat 8 at the tip of the opening / closing cap 3, a narrow woven belt is superposed for a predetermined length in the length direction, and one end of a shock absorber 5 having a shock absorbing portion 11 sewn in multiple threads by a sewing machine is connected. The cushioning portion 11 is folded and stored in the opening / closing cap 3, and the belt at the other end exits from the opening / closing cap 3 and is connected to the waist belt. When the hook of the present invention having the above-mentioned configuration is used and in the unlikely event of a fall, the impact load is transmitted to the shock absorber 5, the buffer portion 11 is torn, and the tearing force acts to buffer the impact. The belt extended by tearing the buffered part 11 of the polymerized belt comes out from the opening and closing cap 3, and the distance between the hook and the waist belt becomes longer than before the crash, but the impact is ensured with a low impact. Is to do. A second embodiment of the present application is shown in FIGS. The safety cap 4 is pivotally supported together with the mounting seat 8 by the thick shaft 12, and the shock absorber 5 is connected to the mounting seat 8 to be housed in the safety cap 4. Compared with housing in the opening / closing cap 3, this structure is simple in structure because it has a thicker shaft and withstands a drop impact load.

[0005]

[Effect of device]

 Adopting the configuration of the present invention as described above has the following effects. By storing the shock absorber in the hook cap, the handleability during work is improved. In other words, as in the past, by connecting it separately from the hook, or by providing the shock absorber that was located at the rope attachment point of the belt integrally with the hook itself, it is possible to get a bra when locking and a bulky waist. It is something that will not happen. The strength of shock absorbers, which are mainly made of synthetic fibers, deteriorates when exposed to ultraviolet rays, but the problem can be solved by housing them in a cap.
