JP3073107U - Rope mounting ring for safety belt at height - Google Patents

Abstract

(57) [Problem] A conventional ring sometimes swings and pivots and thus protrudes from a body, and it is conceivable that an unexpected foreign substance may catch on a foot from a narrow scaffold plate. It was also conceivable that even if they did not step on their feet, they would drop the equipment they had and hinder workers on the lower scaffolds. A ring and a collar are integrally formed of a plate material.
Eliminate the rotation of the ring.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 This application relates to a safety belt for working at heights used for the purpose of preventing a crash disaster when working at a high place such as a construction site.In particular, the safety belt for connecting the building and the worker is used as a safety belt. The present invention relates to a binding ring for a rope connected to a belt.

[0002]

[Problems to be solved by conventional techniques and devices]

 A typical configuration of a safety belt that has been used in the past is composed of a body tightening belt composed of a narrow woven belt with a buckle sewn on one end, and a rope portion connected to a position near the buckle. The rope part is usually made of a 1.5 mm long 10 mm diameter nylon rope with the base end connected to a belt and the end attached with a hook with a double safety device. When connecting the base end of the rope to the body tightening belt, a resin ring mounting plate, generally called collar, is inserted through a predetermined portion of the body tightening belt, and the ring is inserted into the closed space formed by this. Was positioned to prevent movement on the belt and then tied to the ring.

A problem has been found in such a configuration. The ring at the base end of the rope is designed to maintain a predetermined position with respect to the body tightening belt, but the semicircular curved side is allowed to rotate about 180 degrees from the base of the substantially D-shaped base. As a result, the semicircular space was sometimes unexpectedly engulfed, leading to dangerous situations. When moving to the work position, the rope is rolled and put into a storage bag.However, when moving through a narrow passage composed of pipe scaffolds, a bolt that protrudes from a pipe clamp or a cutting procedure that protrudes from the concrete surface However, untreated bolt ends and the like may enter this semicircular space, and walking may be rapidly inhibited. In such a case, it was conceivable to step off the foot from the narrow scaffold. Even if they did not step off their feet, it was thought enough to drop the equipment they had and hinder workers on the lower scaffolds.

[0004]

[Means for Solving the Problems]

 In the present application, in order to prevent such a situation, the problem is solved by improving the ring for attaching the rope portion. The causes of the problems are that the ring has a large semicircular space, and that the ring can rotate freely by 180 degrees, so it may protrude to a position outside the awareness of the wearing worker. is there. If the ropes are tightly bundled and bundled into a storage bag, the rope at the base end is also connected to the ring with a certain amount of tension, so that the ring does not easily rotate freely. However, in many cases, the rope at the joint with the ring is loose because it is stored in a roll rather than bundled, and the ring swings, including the rope at the base end, in accordance with the vibration during walking. Move or rotate. Also, due to operational requirements of the rope, the ring is located on the side of the waist, so when the ring is upright with respect to the waist belt, the width of the waist protrudes to the side by a semi-arc. However, in narrow passages, workers may not be able to avoid their own body against the protruding object, but the consciousness will not reach this protruding point. In addition, since the ring rotates, a predetermined length of rope at the base end of the binding also rotates to the side of the waist following the ring, thereby increasing the space for unexpected foreign matter.

[0005] Therefore, there is a concern about the above-mentioned situation, and in the present application, such a situation is avoided by eliminating the rotation of the ring for attaching the rope. Specifically, the problem is solved by integrally forming the ring and the brim skin from a plate material. If both are integrally formed by the plate material, the rotation of the ring portion is naturally eliminated, and the material cost and the assembly cost of the brim skin can be eliminated in terms of the configuration, and the cost can be reduced.

【Example】

 An embodiment of the present application will be described. The ring 3 of the present invention is provided with a belt passing port 1 in parallel and a rope binding port 2 adjacent thereto by punching a high-strength plate material. A bend of about 15 degrees is provided between the rope binding opening 2 and the belt passage opening 1. This bending is a procedure for lifting the rope binding port 2 from the belt surface for a predetermined distance, and causing the binding section itself to move freely in a semicircular manner within the rope binding port 2 without slidingly contacting the belt. This free movement prevents torsion such as kink from occurring at the rope binding base. When the belt is fastened to the body tightening belt 5, the belt ends are sequentially inserted into the two belt passage openings 1. Therefore, the structure for the same purpose can be obtained directly in one process without using the brim skin as in the related art. As another embodiment, three or four belt passage openings 1 are provided as shown in FIG. 2, but as this number increases, the attachment to the body tightening belt 5 becomes stronger, It is easy to maintain an arbitrary position on the belt 5. However, due to the increase in weight, they are used depending on the purpose of use. Further, as shown in FIG. 3, it is a more convenient configuration to provide a ring portion 31 at a position which is a lower position at the time of mounting so as to hang a tool or the like. In the above embodiment, the plate material is formed by punching, but the same effect can be obtained by forming by cutting or forging.

[0007]

[Effect of the invention]

 By implementing the present invention as described above, it is possible to eliminate an unexpected danger that may have conventionally occurred in a narrow passage. In addition, parts and processes can be reduced in the configuration, and inexpensive provision is possible.
