Abstract

PROBLEM TO BE SOLVED: To solve the problem with a conventional ring for locking with a hook that the ring deviates to a back direction and the ring is difficult to be used in the mounting position of the ring. SOLUTION: A connecting ring section on a take-up machine side situated on the left side of a waist is provided with the ring for locking with a hook integrally therewith or as a separate body to facilitate fitting of the hook of a safety device for preventing a fall during a vertical (ascending and descending) movement and to improve the follow-up property of the safety device during the ascending and descending movement.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a safety belt worn by a worker at a high place on the waist to prevent a fall.

[0002]

2. Description of the Related Art Conventionally, in a wind-up type safety belt, a belt type shock absorber is provided at an end of a winder via a connecting ring, and an attaching ring is provided at an end of the shock absorber. The winder belt having a buckle at one end was inserted through and the winder was used at a predetermined position. This type of safety belt has no problem at the normal horizontal work position (at every one floor) at normal height work (every floor), but it causes a problem when moving vertically (moving up and down). . At the time of vertical movement, a safety device is fitted to the vertical main rope provided along the pillar etc. to prevent the fall, and the hook of the safety device and the trunk belt are connected. No safety ring was placed on the safety belt. Therefore, in order to achieve the above-mentioned purpose, as shown in FIGS. 9 and 10, a measure is taken to attach the retaining ring together with the trunk belt passing portion of the attaching ring.

[0003]

However, at such a position of the latch ring, it is not easy to check the hook of the safety device for fall prevention because it is biased toward the back side too much, and the hook falls when used. In some cases, the safety device did not follow up and down because the child safety cord was pulled too far in the lateral direction, making it difficult to use. Therefore, at the time of vertical movement, you can shift the torso belt and bring the retaining ring to the left side of the waist for use, but if you do so, the buckle will be located around the right hip bone and the hip bone will hurt after long use. It was something that came.

[0004]

SUMMARY OF THE INVENTION Therefore, according to the present application, a connecting ring for connecting a winder of a safety belt located on the left side of the waist and a cushioning body is provided with a retaining ring as a separate body or as an integral body, and the trunk belt is moved. In addition, the safety device is pulled up at an appropriate position during vertical movement so that the safety device can smoothly follow.

EXAMPLES The present invention will be described in detail. In the present application, a belt 4 having a stopper 5 at its tip is housed in a winder 3, and a winder 3 of a wind-up type lifeline is connected via a connecting ring 6. In a safety belt formed by providing a cushioning body 7, providing a mounting ring 8 at the other end of the cushioning body 7, and inserting the trunk belt 2 through the mounting ring 8,
The structure is such that a hooking ring 9 is provided on the connecting ring 6 portion.

1 to 3 show a first embodiment, in which a retaining ring 9 of a U-shaped shackle is connected to the base end of the winder 3 by a rivet 61 separately from the connecting ring 6. It is the one that is indirectly connected to the buffer body 7, and if it falls, the retaining ring 9 of the U-shaped shackle.
When is pulled, the belt loop on the back side of the case of the winder 3 is broken and separated from the body belt, and further pulled by the connecting ring 6 to release the shock absorber 7 from the belt, thereby alleviating the impact load. Therefore, the connecting ring 6 and the attachment ring 8 can be sewn on both ends of the buffer body 7, respectively, and the winding machine 3 and the latch ring 9 can be assembled later.

FIG. 4 shows a second embodiment, in which a hooking ring 9 having a substantially triangular shape is provided separately from the connecting ring 6, and the connecting ring 6 and the hooking ring 9 are provided at one end of the buffer 7. Is directly attached and sewn.

FIG. 5 shows a third embodiment, in which the right side portion (buffer side) of the connecting ring 6 is extended and protruded, and the extension portion is provided with a hole to integrally form the retaining ring 9 portion. is there.

FIG. 6 shows a fourth embodiment in which the left side portion (winder side) of the connecting ring 6 is extended and projected, and the extended portion is bored to integrally form a retaining ring 9 portion. It is a thing.

FIG. 7 shows a fifth embodiment, in which the upper portion of the connecting ring 6 is extended and projected, and the extended portion is provided with a hole, and the retaining ring 9 is integrally formed.

FIG. 8 shows a sixth embodiment in which the upper and lower parts of the connecting ring 6 are extended and projected, the extended part is bent, and the retaining ring 9 is integrally formed. You can hang the hook on the protective cutout.

FIG. 9 is a perspective view of the cushioning body 7 of the present application, in which two belts are woven using synthetic fibers, and a plurality of entangled warp threads thinner than the warp threads and the weft threads of the belt are used to sew the two belts. A buffer unit that weaves the belt together and partially integrates it
71 to form a belt body by temporarily retracting the entangled warp yarns and weaving the two belts separately to form a separating portion, and weaving the buffer portion 71 and the separating portion alternately and continuously. To form a buffer portion 71 on one side by cutting a predetermined portion of the belt body.
A buffer piece is formed by providing a tension piece made of a belt of a separation section on the other side and another bypass belt 72 longer than the buffer body, and one end portion and one tension piece of the buffer body are used. Are also sewn together to provide a connecting ring 6, and the other end portion of the bypass belt and the other tension piece of the buffer body are sewn together and an attachment ring 8 is provided there. . The buffer section 71 is formed by covering the folding heat shrinkable tube.

The method of use of the present application is as shown in FIG.
The hook H of the safety device A for fall prevention fitted to the vertical parent rope R for fall prevention attached to the structure is hooked on the hooking ring 9 located on the left waist of the worker to move up and down the structure. The safety device can smoothly follow and move when moving up and down.

[0014]

As described above, by using the safety belt provided with the retaining ring according to the present invention, at the position of the conventional retaining ring, the hook H of the safety device for fall prevention is biased too far toward the back. Although it was difficult to check the hanging condition, the hanging ring 9 can be arranged on the left side of the torso, at the position of the hip bone, so that the hanging condition can be easily checked. Further, the followability of the vertical movement of the safety device for fall prevention is improved, the working range is expanded, and the efficiency is improved. Further, at the position of the conventional retaining ring, the buffer 7 did not work even if it should drop during vertical movement, but by providing the retaining ring 9 in the connecting ring 6 of the present application, it is possible to prevent The shock absorber acts against the fall, and the impact load due to the fall can be mitigated.
