Description

[Detailed description of the invention]

[0001]

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

[0002]

2. Description of the Related Art As a conventional safety belt used at a construction site, there is a general safety belt having a single rope as shown in FIG. This safety belt has a structure in which a D-shaped ring is movably fixed to one portion of a body fastening belt provided with a buckle at one end by a ring stopper, and a hook is attached to the D-shaped ring via a rope.

[0003]

[Problems to be Solved by the Invention] When the conventional safety belt is used, there is a scaffold, and it can be used without any problem in a place where a horizontal rope is provided along the scaffold, but there is no scaffold. When moving between structures, or where the direction of the horizontal master rope is different, the ropes must be replaced. At this time, the ropes are unprotected, and a crash disaster has occurred at such times. Therefore, in order to eliminate the defenseless state, a safety belt having a structure in which two rope fittings are attached to a body tightening belt has been proposed. However, when only two ropes are attached to a D-shaped ring, as shown in FIG. It is conceivable that the device may be used in a U-shaped hanging state.
It was a safety belt with a structure that could not be used due to the article. If used in a U-shaped hanging state, the rope will be worn or cut at an acute angle such as a corner of a steel frame, and one of the hooks may be used by hanging it on the corresponding D-shaped ring. Was what it was. Then, from the beginning, instead of a D-shaped ring, there is a thought that a ring with a hole only for connecting the rope may be sufficient, but in this case, it was fitted to the parent rope hanging down along with the structure Safety device 9 for fall prevention (for example,
Rolip (registered trademark)) is hung on a hook or a horizontal member, etc., and the wire is entangled and can be pulled out freely. The hook at the end of the wire is connected to the operator's belt for use. There was a problem that the hook of the block could not be connected to the safety belt. In the case of a single rope, it was usual to use a D-shaped ring.

[0004]

Therefore, in the safety belt of the two ropes of the present invention, the shape of the ring for connecting the first rope and the shape of the tip of the hook of the second rope bracket are changed, so that the safety for fall prevention can be obtained. It is possible to obtain a structure which can be connected to the device 9 and the hook 10 of the safety block and cannot be used in a U-shaped hanging state. More specifically, a rope attachment hole 31 for attaching the ring shape to the rope and a hook attachment hole 32 for attaching the safety device 9 for preventing fall and the hook 10 of the safety block.
And the second rope hook 8
The tip of the hook part is a bulged projection 81, and the hook mounting hole 32
The shape is such that it cannot be fitted into.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail.
1 is movably fixed to two places of a body tightening belt 2 provided by sewing with a ring stopper 4 and one end of a rope 6 is satsuma braided into the rope connecting rings 3 and 7. This is a safety belt with hooks 5 and 8 attached to the other end by Satsuma knitting. Ring 3 for connecting the rope of the first rope bracket of this safety belt
And a rope mounting hole 31 where only the rope can be fitted, and a hook
5 Or safety device for fall prevention 9, Hook of safety block
A hook mounting hole 32 into which 10 can be fitted is provided, and a hook 5 is provided in the rope mounting hole 31 via a rope 6. Only the rope mounting hole 71, into which only the rope can be fitted, is attached to the rope connecting ring 7 of the other second rope fitting.
A hook 8 is provided on a 71 via a rope 6, and the hook end of the hook 8 is formed as a protruding portion 81 bulging into a predetermined shape, so that the hook 8 cannot be fitted into the hook mounting hole 32 of the rope coupling ring 3. It is.

[0006] The method of using the safety belt according to the present invention is such that the hook 5 of the first rope fitting is turned around to a structure or a horizontal master rope and hung on its own rope 6, or the hook 5 has a large diameter. If so, use it by directly fitting it to a single pipe. If the direction of movement of the horizontal main line is different where the moving direction changes, hook 8 of the second rope bracket is hung on the horizontal main line, and then hook 5 of the first rope bracket is connected to the structure or horizontal main line. Remove and move.

FIG. 3 shows a working state of the safety belt according to the present invention. When a structural column is lifted or lowered, or where a horizontal master rope cannot be stretched, a vertical master rope is stretched and fitted to the master rope. The connecting hook 10 of the combined fall prevention safety device 9 is fitted into the hook mounting hole 32 of the rope connecting ring 3 to prevent the worker from falling. In a similar place, if the hook 10 of the safety block suspended from the upper beam is fitted to the hook mounting hole 32 and used, the moving range is widened and the workability is improved.

FIG. 4 is an explanatory view of a U-shaped hanging state, in which a rope of a safety belt is turned over a structure, and then a hook is hung on a ring. This type of safety is mainly used at a construction site according to the present invention. The belt cannot be used in this way. Because the structure of the safety belt that can be used in a U-shaped suspension state is defined in Article 6 of the “Safety Belt Standards”, it states that (1) it is equipped with a waist belt, a square ring, and a telescopic adjuster. That (2) The D ring and angular ring shall be attached to the waist belt so that they are fixed at both sides of the abdomen of the person wearing the safety belt. (3) The telescopic adjuster must not fall out of the rope. The safety belt structure of the present invention cannot be used because it does not correspond to the above three items.

[0009]

[Effect of the Invention] The present invention has a structure that does not violate the above-mentioned "Safety Belt Standards" of the Ministry of Labor, conforms to the "Safety Belt Standards", and can be moved while alternately switching structures. Efficiency and safety are improved, and in the safety belt of the present invention type, a dangerous U-shaped hanging state cannot be used, so that the safety of the worker can be ensured.
