DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a safety belt for working at a high place for preventing a worker working at a high place from falling.

[0002]

2. Description of the Related Art Generally, when working at a high place, a safety belt for working at a high place is fastened to the waist of a worker, and a hook with a safety device at the tip of a rope connected to the safety belt is used at a working position at a high place. If a worker steps on a foot and falls off, it will be caught by a rope to prevent a fall, and the safety of the worker will be ensured. Is being ensured.

In the use of the safety belt for working at a high place as described above, when the working position is changed, there is a case where the hook must be replaced. At this time, since it is not connected to the parent net, the horizontal pipe, and the like, there is a danger of falling.

In order to solve such inconveniences, two ropes are connected to a safety belt, hooks with safety devices are connected to the ends of each rope, and one hook is engaged with a parent net, a horizontal pipe or the like. When the hook is changed in the use condition, the other hook is engaged with the parent net or the horizontal pipe, and the one hook is changed, so that the safety belt that can always ensure the safety of the worker is provided. It is proposed in Japanese Utility Model Laid-Open No. 7-33360.

Generally, in a safety belt for working at height, a hook at the tip of a rope with a hook is engaged with a position opposite to the rope connecting position of the safety belt to make the rope U-shaped, so-called U-shaped hanging state. It is obliged to prohibit the use of the system and to ensure the safety of workers.

For this reason, in the safety belt described in the above publication, two ring stoppers are attached to the body fastening belt,
A hooked rope is connected to each ring stopper, and the shape of each ring stopper is specially shaped so that the U-shaped hanging state is not used so that the hook of the other rope is not engaged with the ring stopper.

[0007]

The safety belt disclosed in the above publication requires two specially designed ring stoppers to connect the two ropes to the body tightening belt. There's a problem.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a safety belt for working at heights having two ropes with hooks, which is excellent in operability and inexpensive and can be used in a U-shaped hanging state.

[0009]

In order to solve the above-mentioned problems, according to the present invention, a ring for connecting a rope is attached to a trunk tightening belt having a buckle attached to one end, and a hook with a safety device is attached to the ring. In a safety belt for working at height where a rope with a hook attached to the tip is connected, an auxiliary rope having a hook with a safety device at the tip is connected to the ring, and the auxiliary rope is spaced apart in the length direction of the body tightening belt. In this configuration, the auxiliary rope is inserted into the attached rope guide wheel so that the auxiliary rope is arranged at a position facing the rope with the hook when the body tightening belt is fastened.

Here, the opposing position means a position where the auxiliary belt is arranged on the other side of the waist when the hooked rope is located on one side of the waist in the tightened state of the body fastening belt.

[0011] With the above construction, since only one ring is attached to the body tightening belt, it is possible to prevent the rope from being bridged in the U-shape, and to reliably prevent the use of the U-shaped hanging state. can do.

[0012] Further, in the use state in which the body tightening belt is fastened, since the two ropes are respectively arranged on both sides of the waist, the other auxiliary rope may hinder the hook at the tip of the hooked rope from being disengaged. In addition, a safety belt excellent in operability can be obtained as in the conventional safety belt.

Here, if the auxiliary rope is in a hanging state, the auxiliary rope may obstruct the movement of the worker. In order to solve the problem, it is preferable to attach a storage bag to the body fastening belt and store the auxiliary rope and the hook in the storage bag.

[0014]

Embodiments of the present invention will be described below with reference to the drawings.

As shown in the figure, a plurality of belt pressing belts 2 are provided on one side of the body holding belt 1 at intervals in the longitudinal direction of the belt 1, and both ends of each belt holding belt 2 are attached to the body holding belt 1. Has been sewn.

The body fastening belt 3 has a buckle 4 at one end. The body fastening belt 3 is inserted between the body contact belt 1 and the belt presser 2, and a plate-shaped ring stopper 5 having a plurality of belt insertion holes is attached to the body fastening belt 3.
A ring 6 composed of a D-ring for rope connection is attached to the belt bending portion 3a protruding from the surface side of the ring stopper 5, and the ring 6 has a rope 7 with a hook and an auxiliary rope 8.
The ropes are connected to each other, and hooks 9a and 9b with safety devices are attached to tips of the ropes 7 and 8, respectively.

The auxiliary rope 8 is inserted through a plurality of rope guide wheels 10 attached to the body tightening belt 3 and is pulled out to the other end of the body tightening belt 3. When it is arranged on one side of the waist, the auxiliary rope 8 is arranged on the other side of the waist.

Here, the rope guide wheel 10 is formed by folding a narrow band into two, sewing the folded portion in the width direction to form a loop 10a in the folded portion, and using the two folded bands to tighten the trunk belt 3. The belt 3 is fastened by engagement of female and male snaps 10b attached to the ends thereof.
To be mounted on

A storage bag 11 is attached to the body tightening belt 3, and the auxiliary rope 8 can be stored in the storage bag 11.

The use of the safety belt for working at a high place having the above structure is performed by attaching the belt 9 to the waist by tightening the torso fastening belt 3 with the torso belt 1 inside, and the hook 9a at the tip end of the hooked rope 7 to the working position at a high place. Engage with the parent net and the horizontal pipe of the scaffolding frame, etc. to secure safety.

When the hook 9a is replaced by the change of the work position, the hook 9 at the tip of the auxiliary rope 8 is changed.
b is hooked on a parent net or a horizontal pipe, and in the engaged state, the hook 9a at the tip of the hooked rope 7 is disengaged, or the hook 9a is replaced.

Here, in the use of the safety belt, if the ropes 7 with hooks and the auxiliary ropes 8 are arranged on the same side of the waist, the ropes are likely to be entangled with each other,
When changing the hook, it is necessary to release the entanglement and change the hook, which may deteriorate the operability. However, since each of the hooked rope 7 and the auxiliary rope 8 is disposed at a position facing the waist, and the auxiliary rope 8 is stored in the storage bag 11,
There is no entanglement between the ropes, and the operability of changing the hooks is extremely good.

When two rings for connecting the rope with hook 7 and for connecting the auxiliary rope 8 are attached to the body tightening belt 3, the ropes 7 and 8 may be used in a U-shaped hanging state. However, since only one ring 6 is attached to the body tightening belt 3, U
It is never used as a hanging state and is extremely safe.

[0024]

As described above, according to the present invention, one rope connecting ring is attached to the body tightening belt, and each of the hooked rope and the auxiliary rope is connected to the ring. Can be eliminated, and safety can be improved.

Further, since a conventionally used ring can be used as the ring for connecting the rope, the cost can be reduced as compared with a safety belt using a specially designed ring.

Furthermore, in the tightened state of the body tightening belt, the rope with the hook and the auxiliary rope are arranged at positions facing the waist, so that there is no entanglement between the ropes, and good operability can be obtained as in the related art.

Further, by attaching the storage bag to the body tightening belt, the auxiliary rope can be stored in the storage bag, so that the auxiliary rope does not hinder the change of the working position, and is safe and The position can be changed smoothly.
