Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a safety belt for working at a high place that prevents a worker who works at a high place from falling.
[0002]
[Prior art]
In general, when working at a high altitude, tighten the safety belt for high altitude work on the waist of the worker and stretch the hook with a safety device at the end of the rope connected to the safety belt horizontally at the high altitude work position. Engage with the main pipe and the horizontal pipe of the scaffolding frame, so that even if the operator steps off and falls, it can be caught with a rope to prevent the fall and ensure the safety of the operator It is done.
[0003]
When the work position is changed in the use of the safety belt for working at high places as described above, there is a case where hooks must be replaced. At this time, there is a risk of falling because it is in a non-connected state with respect to the parent net or the horizontal pipe.
[0004]
In order to solve such inconvenience, two ropes are connected to the safety belt, hooks with safety devices are connected to the ends of the ropes, and one hook is engaged with a main net or a horizontal pipe. In this case, when the hook is changed, the other hook is engaged with the main net or the horizontal pipe to change one hook so that the safety of the worker can always be secured. -33360.
[0005]
In general, in a safety belt for work at high places, use of a so-called U-shaped suspended state in which the hook at the tip of a rope with a hook is engaged with the opposite position of the rope connecting position of the safety belt to make the rope U-shaped. It is obligatory to ensure the safety of workers by prohibiting them.
[0006]
For this reason, in the safety belt described in the above publication, two ring stoppers are attached to the belt fastening belt, ropes with hooks are connected to the ring stoppers, and the hooks of the other rope are not engaged with the ring stoppers. The shape of each ring stopper is a special shape so that the U-shaped suspended state is not used.
[0007]
[Problems to be solved by the invention]
As described above, the safety belt disclosed in the gazette has a problem in terms of economy because it requires two specially designed ring stoppers to connect the two ropes to the waist belt.
[0008]
An object of the present invention is to provide a safety belt for working at high places having two ropes with hooks which are excellent in operability and can be prohibited from being used in a U-shaped suspended state and which are inexpensive.
[0009]
[Means for Solving the Problems]
In order to solve the above-described problems, in the present invention, a rope connecting ring is attached to a waist belt having a buckle attached to one end, and a hook with a safety device is attached to the ring. In the connected safety belt for working at high places, an auxiliary rope having a hook with a safety device at the tip is connected to the ring, and the auxiliary rope is inserted through a rope guide wheel attached at intervals in the length direction of the waistband. Thus, a configuration is adopted in which the auxiliary rope is arranged so as to extend from the body fastening belt portion at a position facing the connecting position of the hooked rope in the tightened state of the body fastening belt.
[0010]
Here, the facing position refers to a position where the auxiliary belt is disposed 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 waist belt.
[0011]
If comprised as mentioned above, since only one ring is attached to the waist belt, it is possible to prevent the U-shaped loop of the rope from being used and to reliably prevent the use of the U-shaped suspended state. it can.
[0012]
In addition, in the state of use where the waist belt is fastened, each of the two ropes is disposed on both sides of the waist, so that the other auxiliary rope does not interfere with the engagement and disengagement of the hook at the tip of the rope with the hook. As with the safety belt, it is possible to obtain a safety belt with excellent operability.
[0013]
Here, when the auxiliary rope is in a suspended state, the auxiliary rope may hinder the movement of the operator. In order to solve the problem, it is preferable to attach a storage bag to the waist belt and store the auxiliary rope and hook in the storage bag.
[0014]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0015]
As shown in the figure, a plurality of belt presser belts 2 are provided on one side of the waistband belt 1 at intervals in the length direction of the belt 1, and both ends of each belt presser 2 are sewn to the waistband belt 1. ing.
[0016]
The waist belt 3 has a buckle 4 at one end. The body fastening belt 3 is inserted between the body rest belt 1 and the belt retainer 2, and a plate-like ring stopper 5 having a plurality of belt insertion holes is attached to the body fastening belt 3. A ring 6 consisting of a D-ring for rope connection is attached to the belt bent portion 3a protruding to the surface side of the ring stopper 5, and two ropes, a rope 7 with a hook and an auxiliary rope 8, are connected to the ring 6 respectively. In addition, hooks 9a and 9b with safety devices are attached to the ends of the ropes 7 and 8, respectively.
[0017]
The auxiliary rope 8 is inserted into a plurality of rope guide wheels 10 attached to the waistband belt 3 and pulled out to the other end side of the waistband belt 3, and the rope 7 with a hook is connected to one side of the waist in the tightened state of the waistband belt 3. The auxiliary rope 8 is arranged on the other side of the waist.
[0018]
Here, the rope guide wheel 10 is formed by folding a narrow band in half, sewing the folded portion in the width direction to form a ring 10a at the folded portion, and winding the waistband belt 3 with the two folded bands, It is made to attach to the body fastening belt 3 by engagement of the female / male snap 10b attached to the end.
[0019]
A storage bag 11 is attached to the waistband belt 3, and an auxiliary rope 8 can be stored in the storage bag 11.
[0020]
The use of the safety belt for work in high places having the above-described configuration is performed by attaching the waistband belt 1 with the waistband belt 3 to the waist by fastening the waistband belt 3 and hooking the hook 9a at the end of the rope 7 with the hook at the work place in the high place. Engage with the parent net and the horizontal pipe of the scaffolding frame to ensure safety.
[0021]
When the hook 9a is changed due to the change of the work position, the hook 9b at the tip of the auxiliary rope 8 is hung on the main net or the horizontal pipe, and the hook 9a at the tip of the rope 7 with the hook is engaged in the engaged state. Release or change hook 9a.
[0022]
Here, in the use of the safety belt, if each of the rope 7 with hook and the auxiliary rope 8 is arranged on the same side of the waist, the ropes are likely to be entangled with each other. It becomes necessary to release the hook and change hooks, which may deteriorate the operability. However, each of the rope 7 with the hook and the auxiliary rope 8 is arranged at the opposite position of the waist, and since the auxiliary rope 8 is stored in the storage bag 11, there is no entanglement between the ropes, and the hooks can be replaced. The operability is very good.
[0023]
Further, if two rings for connecting the rope 7 with hook and connecting the auxiliary rope 8 are attached to the body fastening belt 3, the ropes 7 and 8 may be used in a U-shaped suspended state. Since only one ring 6 is attached to the waistband belt 3, it is never used as a U-shaped suspended state and is extremely safe.
[0024]
【The invention's effect】
As described above, in the present invention, since one rope connecting ring is attached to the waist belt, and each of the rope with the hook and the auxiliary rope is connected to the ring, the use of the U-shaped suspended state is eliminated, and the safety is achieved. Can be improved.
[0025]
Moreover, since the ring conventionally used can be used as a ring for rope connection, cost reduction can be aimed at compared with the safety belt | band | zone using the ring of a special specification.
[0026]
Furthermore, since the hooked rope and the auxiliary rope are disposed at the opposite positions of the waist in the tightened state of the waistband belt, there is no entanglement between the ropes and good operability can be obtained as in the prior art.
[0027]
In addition, by attaching the storage bag to the waistband belt, it is possible to store the auxiliary rope in the storage bag, so the auxiliary rope does not interfere with the change of the work position, and it is safe and smooth. Can be changed.
