DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an attachment for a safety belt used to prevent a worker from slipping or falling when working on an inclined surface such as a roof.

[0002]

2. Description of the Related Art Conventionally, in work performed on a roof, for example, mounting of a TV antenna, electric work, snow-falling, etc., there are few equipments for fall prevention, and thus many crashes have been observed. . This is a relatively low position work among high places, and it is thought that it is possible to be careless, but the main cause is that there is no appropriate standing structure on the roof, and the hook of the safety belt is locked. It was difficult.

[0003] Therefore, poles are installed at both ends of the building,
In the meantime, a rope is stretched, and a hook of a safety belt is locked to the rope, or a rope in the direction of the eaves is inserted or locked and hanged freely, and a hook and a safety device of the safety belt are attached to it. An anchoring method was used. This method takes a long time to prepare and requires more time than the original working time, so that it is often not used after all, and as a result, the occurrence of accidents does not decrease. Also, even if adopted, the rope gradually became loose and difficult to handle.
The present application discloses a safety belt mounting device that can be temporarily and easily and safely installed temporarily in order to eliminate a crash disaster during work on a roof.

[0004]

SUMMARY OF THE INVENTION In the present application, instead of a conventionally used three-stroke rope which is heavy and bulky, a flexible and lightweight synthetic fiber is used so that a safety belt attaching device can be temporarily and safely installed. The narrow woven belt is used, and hooks are provided at both ends for locking to the wife of the roof, and the telescopic operation rod inserted through the belt can be freely separated and joined to the hooks for dangerous eaves. The hook can be locked by holding the operation rod without approaching. In addition, considering operability and carrying time,
The central part of the belt is divided into two parts by a belt tensioner, and a locking tool is provided at one end of the narrow woven belt.
A child rope portion provided with a connecting ring at the other end is inserted and locked to the above-mentioned parent rope portion, and a safety belt is locked there to prevent falling. In addition, a method is also possible in which one eaves is stretched over the ridge to the other eaves, and a hook of a safety belt is hooked on a ring at a predetermined position provided on the belt.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS According to an embodiment of the present invention, a substantially U-shaped hook 2 is connected to one end of a narrow woven belt 1 via a carabiner sewn to the one end of the narrow woven belt 1, and can be joined and separated to the base end of the hook 2 Next, two operation rods 3 which are superposed and stretched on the belt 1 are prepared.
A ratchet-type belt tensioner 4 is used to connect the two, and one end of the belt is wound around the connection shaft 41 and securely sewn, and the other is inserted through a rotation shaft 42 and wound. is there. Further, on the belt 1, a predetermined number of ring portions 11 in which a belt of the same quality is firmly sewn are provided. The hook portion 2 is formed in an approximately U-shape using an aluminum square pipe member 21, a continuous reinforcing plate 22 is welded to three outer sides, and a plate 23 slightly wider than the square pipe member is welded to the inner side. Attaching the nylon sheet material 24 to protect the member located inside the hook 2 and welding the connecting ring 25 connected to the carabiner sewn to the end of the belt 1,
The coupling pin 26 is always provided so as to protrude by the bias of the spring,
The stopper 27 of the operation rod 3 is screwed and fixed with a thumb screw. The operation rod 3 is made of resin and has a structure in which two thick and thin cylinders are superimposed to be short, and the belt 1 passes through the inside of the cylinder.
One end has a hole for fitting to the above-mentioned coupling pin 26 and rigidly joining with the hook 2. The belt tensioner 4 is generally used. The belt tensioner 4 winds the belt 1 onto the rotating shaft 42 by operating a lever, and prevents the belt 1 from returning by a ratchet to maintain the length of the belt 1. The parent rope is constituted by the pair of belts 1 described above. In addition, a hook 6 or other fastener 6 is sewn to one end of the similar narrow woven belt 1, and a connecting ring 7 is sewn to the other end to provide a child rope portion.

[0006] In order to mount the mounting fixture of the present invention on the roof, first, the operating rod 3 is extended, joined to the hook 2 and fixed with the connecting pin 26, and the operating rod 3 is connected to the belt tensioner 4 side. Hold the end, and hook the hook 2 on both ends and eaves near the top of the roof. Then, the belt tensioner 4 is operated to stretch the belt 1. Next, rotate the cord to the belt 1 and the ring 11 to connect the ring 7
The installation work is completed by hooking the locking device 6 on the. The worker performing the construction is to use the hook 8 of the safety belt hung on the connecting ring 7, and to move the work position, the child rope is moved to an appropriate position on the parent rope. is there. It is also possible to insert the connecting ring 7 through the belt 1 in advance, and to select and use the rope according to the length of the roof toward the eaves. FIG. 7 is a view in which the hook 8 of the rope fitting of the safety belt is directly wound around the ring portion 11. The operating rod 3 in use disengages the joint with the hook 2 and contracts it. this is,
Should the worker slip, the belt 1 is pulled down, the control rod 3 bends, and the hook 2 rigidly connected to the tip of the control rod 3 moves unexpectedly or is damaged. Then, it is to prevent it from coming off the wife of the roof. When removing, the operating rod 3 is extended and joined to the hook 2, and the lever of the belt tensioner 4 is operated to loosen the belt 1. Next, hold the control rod 3 and remove it from the both ends of the roof or the eaves to complete the work.

[0007]

As described above, according to the present invention, the main rope portion is constituted by a belt, so that it is inexpensive, lightweight, low in bulk, compactly stored, and easily carried and transported. In addition, because it is lightweight, it is easy to install, there is little loosening when tensing, and because it is a thin width weave, the thickness is thin, so even if it is installed on the roof, workers will not catch on feet and it is safe. The entire roof can be moved. In addition, since the operating rod 3 is provided, it is not necessary to go to the roof end when attaching the hook to the roof end.
Dangerous operation during installation can be eliminated.
