Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to a safety belt, and particularly relates to a safety belt that secures a safety belt used for work on utility poles, steel towers, etc. in a safe and easily removable manner. .

(Conventional technology) Conventionally, when working at high places such as telephone poles and steel towers, construction tools and members used for construction such as insulators, electric wires, bolts and nuts were raised to the work site as necessary. Access ropes are used to transport tools that are no longer needed, parts that have been replaced, etc. from the work area. The items to be raised or lowered can be tied directly to this rope or placed in a small basket-like basket tied to this rope, and workers at the work site can hoist or lower the items to high places. This method, which uses a rope to go back and forth between the work place and the ground, does not require the construction of special scaffolding or the use of large-scale machinery such as cranes, so it is a simple method. This is often used in reality.

However, when the rope is lowered and not in use, passing vehicles may hook one end of the rope that is not fixed, putting the worker at the other end of the rope in danger. The drawback was that there was a risk that the system would fall into a trap and cause an accident. It would be fine for workers on the ground to pay close attention to vehicle traffic, etc., and to tie the ropes to utility poles, steel towers, etc. when they are not in use, but it is important to tie and untie the ropes one by one. The work involved in these ropes is time-consuming and troublesome, and they are not necessarily appropriate in actual use, and there is a possibility that accidents may occur when vehicles or other vehicles become stuck on these ropes.

(Purpose of the invention) The present invention has been developed in view of the above points, and its purpose is to provide a safety belt for access ropes that can be used for work on utility poles, steel towers, etc. and that can easily and safely secure access ropes. It's about doing.

(Structure of the invention) The structure of the invention, which was made to achieve the above object, is to removably connect both ends of a flexibly bendable plain strip to within a predetermined range. A return rope to which a surface fastener is attached so as to form a ring-shaped endless band with a desired folding diameter, and a return rope fixing member is attached to a portion that becomes the surface when the endless band is formed. The gist is safety belts.

Here, various modes can be considered for the carrying rope fixing member, but for example, the carrying rope fixing member may have one end fixed to the surface of the bare strip forming the endless strip and the other end removable by a hook-and-loop fastener. The rope fixing member is formed by another flexible strip to be fixed, and the loop fixing member is fixed at the center to the surface of the strip forming the endless strip, and is removably fixed at both ends with hook-and-loop fasteners. One embodiment of the present invention may be one formed by another flexible plain belt, or one using a conventionally known marker belt as a plain belt forming an endless belt.

(Example) Examples of the present invention will be described below with reference to the drawings.

Fig. 1 is a perspective view showing the safety belt of an embodiment of the present invention; Fig. 2 is an explanatory view showing the safety belt shown in Fig. 1 attached to a telephone pole with one end of the cable fixed; FIG. 3 is an explanatory diagram showing an example of the use of the safety belt according to the embodiment of the present invention.

The safety belt is a horizontally long yellow belt that can be flexibly bent, i.e., a vinyl sheet 1 in Figure 1.
is the main body, and three plastic-molded engagement bands 2 with hook-shaped needles standing on the surface of one end thereof are sewn at equal intervals in the longitudinal direction of the vinyl sheet 1. On the other end of the vinyl sheet 1, three plastic-molded engaging bands 3 made of cotton wool are sewn at equal intervals in the width direction of the vinyl sheet 1. The engaging band 2 on the front surface of the vinyl sheet 1 and the engaged band 3 on the back surface of the vinyl sheet 1 are attached as surface fasteners when forming the vinyl sheet 1 as an endless band.

Further, 5 is a vinyl french constituting the carrying rope fixing member, the center of which is sewn to the vinyl sheet 1, and the sides facing the vinyl sheet 1 at both ends are provided with engagement bands 2. An engagement band 7 made of the same material is sewn on. On the other hand, engaged bands 8 are sewn at positions on the surface of the vinyl sheet 1 corresponding to the engaging bands 7 at both ends. Further, reference numeral 9 denotes a rubber band, which is sewn in three places in the longitudinal direction of the vinyl sheet 1 in a stretched state. Therefore, the vinyl sheet 1 has some elasticity in the longitudinal direction. The rope safety belt 10 is constructed by the combination of the above-mentioned parts.

Therefore, this safety belt 10 can be wrapped around utility poles, steel poles, etc. with different diameters, and the engaging belt 2 and the engaged belt 3 can be tied together.
can be engaged with each other at a necessary position and fixed to a utility pole 12, for example, as shown in FIG. Since utility poles and steel poles have a tapered shape toward the top, the safety belt 10, once wrapped, is securely held on the utility pole or the like. Then, one end of the access line 17 lowered toward the ground by the worker 15 (illustrated in FIG. 3) on the utility pole 12 is connected to the engagement band 7 of the frenulum 5 of the access line safety belt 10 on the vinyl sheet 1. engaged band 8
Once removed, it can be firmly fixed by sandwiching it between the frenulum 5 and the vinyl sheet 1 as shown in FIG. If the carrying rope 17 is long, it can be tied into a bundle and fixed between the frenulum 5 and the vinyl sheet 1, or the carrying rope safety belt 1 can be fixed as long as it does not get caught in passing vehicles.
It is also possible to fix in such a way that the rope 17 beyond the part fixed at 0 reaches the ground.
It is also possible to use two ropes and fix the ends of the two ropes.

Therefore, for workers 15 who work at high places such as utility poles and steel towers, one end of the above ground side of the access rope 17 used for raising and lowering work tools and construction materials, etc., is used when not in use. It can be easily and securely fixed to the safety belt 10 attached to the lower part of the safety belt 17, so that passing vehicles etc.
The problem of jeopardizing the safety of workers by causing them to get caught has been resolved. In addition, since the vinyl sheet 1 has hook-and-loop fasteners (engaging band 2 and engaged band 3) attached to both ends, the diameter of the vinyl sheet 1 formed into a ring can be varied by the length of the hook-and-loop fasteners. It can be easily but reliably fixed to utility poles, steel towers, etc. of different thicknesses (diameters). Also, it is easy to remove.

In addition, since the rope safety belt 10 is made of a flexible vinyl sheet, it has excellent portability as it can be folded and carried, and has the advantage of being able to be used anywhere.

The rope safety belt according to the present invention can be constructed in various ways other than the above-mentioned embodiments. For example, a rope safety belt 10' shown in FIG. 4 has an engaging belt 2' and an engaged belt 3' at both ends of a yellow vinyl sheet 1', and the middle part of the surface thereof is similar to the above-described embodiment. Then, one end of the frenulum 25 is sewn to the vinyl sheet 1', and the other end is sewn to the engaging band 7' sewn to the frenulum 25 and the engaged band 8' sewn onto the vinyl sheet 1'. It is a yellow vinyl sheet 1' with the words ``Caution Overhead'' dyed on it, which also serves as a sign band. When work is carried out at high places such as utility poles, signs that call for the attention of passers-by such as "Be careful above your head" and "Under construction", as well as signs necessary for the work such as "Do not transmit power" are often used. ,The use of both the sign belt and the safety belt for walking ropes is
It is also suitable from the viewpoint of work efficiency and transportation. Needless to say, this embodiment has the same effect as the first embodiment in securing the rope.

Fig. 5 shows another embodiment of the safety belt, and in the figure, 20 is a vinyl sheet forming an endless belt, and 22 is a vinyl sheet 20 sewn diagonally on the front side of one end as shown in the figure. 23 is an engaged band sewn to the other end of the vinyl sheet 20 at an angle perpendicular to the engaging band 22, and 25 is a vinyl sheet with its center sewn as a fixing member for the cable. Each represents a frenulum sewn onto the sheet 20. The attachment of the frenulum 25 and the vinyl sheet 20 is similar to that of the frenulum 5 of the first embodiment.
Since the installation is the same as that of the vinyl sheet 1, the explanation will be omitted. In this embodiment, the vinyl sheet 20
Snaps 30 to 31 (back side) and 32 to 34 (front side) are attached to the middle part of the vinyl sheet 20 to adjust the length by folding the middle part of the vinyl sheet 20 to the back side. Snaps 30 and 31 and snap 32 are used when attaching this safety belt to a utility pole with a small diameter, where the length cannot be adjusted only by acting as a hook-and-loop fastener formed by the engaging band 23. and 33 respectively, when the vinyl sheet 20 is made into a ring shape, the diameter is made smaller, so that it can be securely fixed to utility poles etc. with such small diameters. By fitting the snaps 30 and 31 and the snaps 32 and 34, respectively, the diameter of the ring can be further reduced. Therefore, in addition to the effects of the first embodiment, this embodiment has the advantage that the range of folding diameters that can be realized is expanded, and it can be used for utility poles, steel towers, etc. with smaller diameters.

Furthermore, the safety belt of the present invention can be used not only on the ground side of utility poles, etc., but also on the upper part of utility poles, etc. where work is being carried out, as shown in FIG. A safety belt 10 that is attached to the top of a utility pole 12 by wrapping a commuter rope 17 that is not used by the worker.
In this case, even if vehicles with high loading platforms come and go and the rope 17 is tied at the top, the safety of the workers will not be threatened.

In the above embodiments, the frenulum was sewn and fixed to the vinyl sheet forming the main body, but it may also be fixed by welding or gluing.

In addition, in the above embodiment, the rope fixing member is realized by fixing a frenulum made of the same material as the vinyl sheet that forms the main body of the rope safety belt to the surface of the vinyl sheet body with a hook-and-loop fastener. It is also possible to form a return rope fixing member by attaching to the surface of the endless belt a strong bag that can be used to bundle and store returnable ropes, a simple cable tie, or a hook that allows the returnable rope to be easily wrapped around. It can be considered as an example of a versatile aspect of the invention.

Although several embodiments of the present invention have been described above, the present invention is not limited to these embodiments in any way, and can be implemented in various ways without departing from the gist of the present invention. Of course.

(Effects of the invention) As detailed above, the rope safety belt of the present invention removably connects both ends of the flexibly bendable plain belt to a predetermined range. A hook-and-loop fastener is attached so that a ring-shaped endless belt with a desired diameter can be formed inside the belt, and a rope fixing member for fixing the rope is attached to the part that becomes the surface when the endless belt is formed. The gist is:

Therefore, the safety belt according to the present invention can be easily fixed to the utility pole, steel tower, etc. where work is being carried out, and has the excellent effect of being able to easily and securely fix the safety belt. . As a result, the end of the line used by the worker can be held securely at all times, which solves the problem of the line being hit by passing vehicles and threatening the safety of the worker. If the safety belt of the present invention is used, the safety of the worker will be sufficient to deal with this problem. In addition, according to the safety belt of the present invention, it is possible to deal with utility poles, steel towers, etc. of different thicknesses with a single safety belt, and the safety belt itself is not bulky. Excellent portability,
It also has the advantage of being able to be used anywhere and requiring no effort to attach or remove.
