Description

[Detailed Description of the Invention] The present invention is used by fitting into a ring attached to a pole-mounted safety belt for fall prevention in order to stop the ring from rotating.

Conventionally, this type of ring 4 has been used by attaching one side of the ring to a body support belt 6 through a complementary belt 5, and overlapping an outer tightening belt 7 thereon. However, since the ring piece 4 is attached to a one-sided belt, it rotates freely using the attachment part as a fulcrum, which makes it difficult to operate when hooking or removing a hook or the like from the ring 4. , accidental falls could occur due to mislatching, etc.

The purpose of this invention is to eliminate and improve the shortcomings of the conventional products, and to make it possible to safely and securely attach and detach the safety belt by holding the ring in a fixed direction after the safety belt is attached to the worker's body. That is.

Aspects of the present invention will now be described in detail with reference to an embodiment illustrated in the accompanying drawings.

As shown in the figure, in this embodiment, both ends of two parallel middle pieces 2, 2 are connected to each other to form an endless shape, and by bringing both middle pieces 2, 2 close together, It has a structure in which ring fitting parts 1 and 1 are connected to each other through a communication groove 11, and a tongue piece 3 is provided protruding from one side of one middle piece 2, and these parts are integrally molded using a synthetic resin material. This is what I did.

To use the present invention, first remove the outer tightening belt 7 from the ring 4, attach the ring 4 to the body support belt 6, and then connect the tip of the ring 4 to the connecting part between the middle pieces 2, 2. When the ring 4 is inserted into the groove 11 and the inner pieces 2, 2 are opened to both sides and the ring 4 is inserted, the side pieces 41, 41 of the ring 4 are inserted into the ring fitting portions 1, 1.
Insert and install each. Thereafter, when the outer tightening belt 7 is passed through the ring 4, the tongue piece 3 is pushed by the outer tightening belt 7, so that the ring 4 can be maintained in a state facing in a predetermined direction. Normally, this type of safety belt is attached to the body by the outer tightening belt 7, so while it is worn, it is held in a fixed direction, and when it is not worn or when the outer tightening belt 7 is loosened, it can be held on the left or right side. Or ring 4 in any direction forward or backward.
can be rotated.

The present invention is constructed as described above, and by fitting this into a ready-made ring 4 and attaching a belt, the ring can be held in a predetermined direction.
Additionally, the ring does not move when the hook is attached or removed, making the operation easy and safe.

Furthermore, since the present invention is integrally molded from synthetic resin, it is easy to manufacture, and since it has elasticity, it can be easily fitted into and removed from the ring.

Furthermore, even when a tensile load is applied to the ring and some rotation of the ring is required, the flexibility of the tongue piece 3 can be used to cope with the situation, which is a remarkable effect.

FIG. 4 shows a second embodiment of the present invention, in which a middle piece 2 is formed of one piece, a tongue piece 3 is provided protruding from one side thereof, and ring fitting parts 1, 1 are provided at both ends, respectively. This embodiment is different from the first embodiment in that the ring fitting part 1 has an opening, and the opposite pieces 41, 41 of the ring 4 are fitted into the opening.
Other functions and effects are equivalent.

FIG. 5 shows a third embodiment of the present invention, in which the middle piece 2 is formed into two pieces as in the first embodiment, and a tongue piece 3 is attached to one side of each of the two middle pieces 2, 2. , 3 are provided in a protruding manner from the first embodiment, but the other functions and effects are the same. However, in this case, it can be fitted into the ring regardless of whether it is front or back.

FIG. 6 shows a fourth embodiment of the present invention.
By connecting both ends of the middle pieces 2, 2 to form an endless shape, and providing protrusions 12, 12 on the inside near both ends of the middle pieces 2, 2, a ring can be fitted to the sides of both ends. Although this embodiment differs from the first embodiment in that parts 1, 1 are provided, the other functions and effects are the same. FIG. 7 shows a fifth embodiment of the present invention, which is similar to the first embodiment in that ring fitting portions 1, 1 with partially opened portions are provided at both ends of the two middle pieces 2, 2. However, the other functions and effects are the same.

In the first embodiment, it is integrally molded using synthetic resin, but it may also be formed using an aluminum alloy material, iron plate, etc. In that case, the communication groove 11
After fitting into the ring 4 with a wide shape, hold down one middle piece 2 and separate both middle pieces 2, 2 as shown in Fig. 1.
If it is placed close to the ring, it will not come off the ring.
