FIG. 5 is an external view of the safety belt 7 of the seventh embodiment of the present invention around the tip of the rope 32. It is a figure which shows the use example of the conventional pole safety belt 101.

1A and 1B are external views of the safety belt 1 according to the first embodiment of the present invention. FIG. 2A is an enlarged view around the tip of the rope 32 of FIG. 1, and FIG. 1B is a fixture 41. It is an enlarged view around the tip portion of the rope 32 before mounting. FIG. 3 is a diagram showing a state in which the safety belt 1 of the first embodiment is fixed to the scaffolding bolt 302 attached to the utility pole 301, and FIG. 4 is a diagram showing a usage example of the safety belt 1.

The safety belt 1 is a pillar safety belt capable of U-shaped fishing work, and is via an auxiliary belt 21 and a square ring (V square ring) 25 which are connected to the body belt 11 and the body belt 11 via a belt retainer 15. A lanyard 31 connected to the auxiliary belt 21 is provided.

The body belt 11 is an elongated strip-shaped belt, which has a buckle 12 at one end, a belt loop 13 near the buckle 12, and a tip metal fitting 14 at the other end. The body belt 11 is inserted into the belt retainer 15 attached to the auxiliary belt 21, and is connected to the auxiliary belt 21 via the belt retainer 15.

The auxiliary belt 21 is a belt-shaped belt that is wider and shorter than the body belt 11, and is a square ring for fixing the expansion / contraction adjuster 37 of the lanyard 31 to the end of the body belt 11 on the buckle 12 side. (V square ring) 25 is attached, and two D rings 26 are attached to the other end.

The lanyard 31 includes a rope 32, a hook 35 attached to the tip of the rope 32, and an expansion / contraction adjuster 37 that holds the rope 32 in a stretchable manner. The rope 32 is provided with a sword knitting portion 33 at the tip end portion, and a thimble 34 for connecting the hook 35 is provided at the tip end side of the shaving knitting portion 33. A fixture 41 is attached to the satsuma knitting portion 33. The fixture 41 is a characteristic portion of the safety belt 1, and this point will be described later.

The hook 35 has a connecting tool 36 at the base end portion, and the connecting tool 36 is locked to the thimble 34. The expansion / contraction adjuster 37 includes a connecting tool 38 that locks to the angular ring (V angular ring) 25, and locks the connecting tool 38 to the angular ring (V angular ring) 25.

In the safety belt 1 including the above, the other configurations except for the fixture 41 attached to the satsuma knitting portion 33 which is the tip end portion of the rope 32 are the same as those of the known pillar safety belt. In other words, the safety belt 1 can be said to be a pole safety belt formed by attaching a fixture 41 to the tip of a rope of a known pole safety belt.

The fixture 41, which is a feature of the safety belt 1, has a rope 32 and a hook 35 when the safety belt 1 is used, as shown in a usage example described later, and a pole fitting such as a scaffolding bolt 302 attached to a utility pole 301. It is a member for fixing to.

The fixture 41 is composed of six flat plate-shaped magnets (magnet pieces) 51 having the same shape, and the magnet pieces 51 are arranged directly on the rope knitting portion 33 in a hexagonal shape without gaps, and vinyl tape is provided at both ends. 52 is wound and fixed to the rope 32. In the present embodiment, the cross-sectional shape of the fixture 41 fixed to the rope 32 is a hexagon, but the cross-sectional shape is not limited to a specific shape, such as a triangle, a quadrangle, or an octagon. It may be a polygon, a circle, a bow, or the like. When the cross-sectional shape is a polygon, it does not have to be a regular polygon.

When the safety belt 1 is used, the fixture 41 temporarily fixes the rope 32 and the hook 35 to the scaffolding bolt 302 or the like by adsorbing to a metal member such as a scaffolding bolt 302 or an arm metal attached to the utility pole 301. (See FIGS. 3 and 4). The suction force to the metal member is proportional to the magnetic force of the magnet 51 and the contact area with the metal member to which the magnet 51 is attracted. Since the suction destination is often a flat surface, it is possible to use a magnet 51 having a small magnetic force by using a fixture 41 having a large flat surface portion, and the options for the magnet 51 are expanded.

From the viewpoint of increasing the contact area with the metal member to be attracted, the cross-sectional shape of the fixture 41 is better to be a quadrangle than a hexagon, but the cross-sectional shape of the satsuma knitting portion 33 is almost circular. When the cross-sectional shape of the fixture 41 is a quadrangle, the amount of protrusion of the corner is larger than that of the hexagonal fixture 41, and the fixture is easily caught by another object. When the cross-sectional shape of the fixture 41 is a quadrangle, it is preferable to chamfer the corners.

Regarding the size (dimensions) of the fixture 41, the larger the cross-sectional area of the fixture 41 and the longer the fixture 41, the larger the contact area with the metal member to be attracted to, but the amount of protrusion from the rope 32. Becomes larger and becomes easier to get caught in other things. In the present embodiment, the length of the fixture 41 is substantially the same as that of the sword knitting portion 33, but the length of the fixture 41 is not particularly limited, and even if it is shorter than the sword knitting portion 33, it is reversed. May be long.

The thickness of the fixture 41 is not particularly limited, but if it is made unnecessarily thick, the fixture 41 becomes heavy, and the rope 32 to which the fixture 41 is attached becomes heavy, resulting in poor workability and usability. This point also applies to the length of the fixture 41.

The type of the magnet 51 is not particularly limited, and rare earth magnets such as alnico magnets, ferrite magnets, neodymium magnets, and samarium-cobalt magnets can be used. Further, a rubber magnet, a plastic magnet, or the like formed by mixing magnet powder and synthetic rubber or magnet powder and synthetic resin can also be used.

The magnet 51 preferably has a high magnetic force, and considering the usage mode, the magnet 51 is attracted to the lower surface of the scaffolding bolt 302 or the like attached to the utility pole 301 as shown in FIGS. 3 and 4, and the rope 32 and the rope 32 and the magnet 51 are in this state. It is preferable that the hook 35 can be in a suspended state. Since the attractive force of the magnet 51 to the metal member is proportional to the magnetic force (magnetic force characteristics) of the magnet 51, if a magnet having a high magnetic force is used, the rope 32 and the hook 35 can be fixed even if the metal member to be attracted is small. be able to. In addition, the magnet 51 is made smaller and lighter, and the degree of freedom in the shape of the fixture 41 is increased.

In this safety belt 1, the fixture 41 can be attached to the existing lanyard 31 later (hereinafter referred to as a retrofit type), and the magnet 51 is composed of a plurality of magnet pieces 51. At the stage of manufacturing the lanyard 31 If so, an integrated magnet can be used.

As a method of fixing the magnet 51 to the satsuma knitting portion 33, an adhesive tape such as gum tame or cellophane tape may be used in addition to the vinyl tape 52. As the fixing means other than the adhesive tape, there are adhesives, wires, strings, bands, crimping and the like, and they may be appropriately selected and used according to the form of the fixture 41 and the like. For crimping, a fixture having a diameter slightly smaller than the outer diameter of the satsuma knitting portion 33 is used, installed so as to cover the satsuma knitting portion 33, and the fixture is fixed using the elasticity of the satsuma knitting portion 33. How to do it.

The attachment position of the fixture 41 to the rope 32 is preferably a position close to the hook 35 from the viewpoint of the usage mode of the safety belt 1, and the sword knitting portion 33 which is the tip of the rope is a preferable position. Since the rope 32 is replaced when the safety belt 1 is used by removing the hook 35 from the D ring 26, it will be easier to work if the hook 35 held in the hand can be fixed to the metal member. (See FIG. 4).

Further, since the satsuma knitting portion 33 is thicker than the other portion (main body portion) of the rope 32 (see FIG. 2B), when the fixture 41 is attached to this portion, the area of the fixture 41 is increased. can do. Since the satsuma knitting portion 33 is originally a portion that is difficult to bend, even if the fixture 41 is attached to this portion, the function of the rope 32 is not significantly affected. From these points as well, the satsuma knitting portion 33 can be said to be a preferable mounting position for the fixture 41.

The method of using the safety belt 1 is basically the same as that of the conventional pole safety belt 101. However, since the fastener 41 is attached to the satsuma knitting portion 33 which is the tip of the rope in the safety belt 1, the work can be performed easily and safely by using the fixture 41 as shown below. be able to.

FIG. 3 shows a state in which the fixture 41 is attracted to the lower surface of the scaffolding bolt 302 attached to the utility pole 301, and the rope 32 and the hook 35 are suspended. FIG. 4 shows a state in which the fixture 41 is attracted to the pole band 303 attached to the utility pole 301. As can be seen from these, in the work on the utility pole 301, the tip 33 of the rope does not hang down when the rope 32 is replaced, and the hook 35 can be placed near the hand.

By using the fixture 41 in this way, the rope 32 and the hook 35 can be temporarily fixed (temporarily fixed) to the scaffolding bolt 302, the pillar band 303, etc., and the rope can be held in a stable working posture and a comfortable posture. 32 can be replaced. This leads to shortening of work time and reduction of worker fatigue. As described above, the safety belt 1 is an easy-to-use safety belt, and the lifting pillar work and the like can be safely performed.

As described above, the fixture 41 attached to the safety belt 1 is attracted to metal members such as the scaffolding bolt 302 and the pole band 303 attached to the utility pole 301 to temporarily fix the rope 32 and the hook 35. Therefore, it is natural that the magnet 51 needs an attractive force capable of supporting the rope 32 and the hook 35 in a state of being attracted to the metal member. On the other hand, if the attractive force of the magnet 51 is increased more than necessary, it is unsafe because it is unexpectedly attracted to the metal member. In addition, it becomes difficult to remove the fixture 41 adsorbed on the metal member.

The suction destination of the fixture 41 attached to the safety belt 1 is not particularly limited. When the safety belt 1 is used in the work of the utility pole 301, the pole fitting can be used as the suction destination of the fixture 41. Here, the pole metal fitting refers to a metal metal fitting attached to the utility pole 301, and is a metal fitting such as a scaffold, a cable metal fitting, an arm tie, a band such as a scaffolding band 303, and an electric wire supporting hardware such as a strap. , Metal fittings for supporting equipment such as high-pressure cutouts, scaffolding bolts 302, scaffolding hardware, scaffolding such as work scaffolding, and hardware for pole equipment such as transformer mounting hardware.

As a method of fixing the magnet piece 51 to the rope 32, an adhesive tape may be used as in the safety belt 1. The magnitude, size, weight, etc. of the suction force of the fixture 42 may be considered in the same manner as the fixture 41 of the first embodiment, and in this respect, the same applies to the fixtures shown in other embodiments. ..

The method of use and the effect of the safety belt 2 are the same as those of the safety belt 1. Comparing the safety belt 2 and the safety belt 1, the safety belt 2 has a wider width of one magnet piece 51. Therefore, the contact area with the metal member which is the adsorption destination can be increased. On the other hand, the amount of protrusion from the outer peripheral surface of the rope 32 is large.

Since the diameter of the sashimi knitting portion 33 is larger than that of the rope 32, a step is likely to occur between the fixture 42 covering the satsuma knitting portion 33 and the rope 32 as shown in FIG. Since such a step is easily caught by an object, it is preferable to wrap an adhesive tape around this portion, cover it with a cap, or remove the step by some other method. The same applies to the fixtures shown in other embodiments.

In FIG. 9A, the fixture 46 is attached to the satsuma knitting portion 33 (not shown) which is the tip of the rope, and the round bar (not shown) is pressed parallel to the center of the upper surface of the fixture 46 in the lateral direction. It has a dent 89. In FIG. 9B, the fixture 46 is attached to the satsuma knitting portion 33 (not shown) which is the tip of the rope, and the front surface (front side in the drawing) of the fixture 46 is pressed against the wall to provide the flat portion 90. Is.

Since the fixture 46 has flexibility, it is wound around the sword knitting portion 33, and the back surface 91 of the support 84 is fixed to the shaving knitting portion 33 by an adhesive. The method of fixing the fixture 46 to the satsuma knitting portion 33 may be a method other than the adhesive.

The method of use and the effect of the safety belt of the sixth embodiment in which the fixture 46 is attached to the tip 33 of the rope are the same as those of the safety belt 1. The fixture 46 of the present embodiment can also be used as a retrofit type fixture. Since the shape of the fixture 46 can be changed in the safety belt of the sixth embodiment, the fixture 46 can be deformed according to the shape of the metal member to be attracted to. As a result, the contact area between the fixture 46 and the metal member to be attracted to is increased, and the rope 32 and the hook 35 can be fixed to the metal member even with the magnet 87 having a small magnetic force.

FIG. 10 is an external view of the safety belt 7 of the seventh embodiment of the present invention around the tip of the rope 32. The same components as those of the safety belt 1 shown in the first embodiment shown in FIGS. 1 to 4 are designated by the same reference numerals, and the description thereof will be omitted.

The basic configuration of the safety belt 7 is the same as that of the safety belt 1 of the first embodiment, but the form of the fixture 47 and the mounting position of the fixture 47 are different. In each of the safety belts of the first to sixth embodiments shown above, fixtures 41 to 46 are attached to the satsuma knitting portion 33, which is the tip of the rope, so as to cover the satsuma knitting portion 33. The safety belt 7 does not have a fixture on the satsuma knitting portion 33. In the safety belt 7, instead of attaching the fixture to the tip 33 of the rope, the connector 47 that connects the hook 35 to the rope 32 is magnetized to form a magnet, which functions as the fixture 47.

In the connecting tool 47, the base end portion of the U-shaped metal rod 95 is connected by the disk-shaped member 96, and the disk-shaped member 96 is rotatably connected to the hook 35. The connector 47 is magnetized to form a magnet and can be attracted to a metal member. The connector 47 is larger than the connector 36 used in the safety belt 1 and the like of the first embodiment. This is to facilitate contact with the metal member to be adsorbed and to secure a contact area. Instead of using the magnetized connector 47, a magnet may be attached between the hook connector and the rope 32.

The method of use and the effect of the safety belt 7 are the same as those of the safety belt 1. The safety belt 7 of the seventh embodiment uses a connecting tool 47 made of a magnet, and this is a fixing tool 47 for fixing the rope 32 and the hook 35 to the metal member. Therefore, the structure is simple and the existing safety belt can be used. Can also be easily applied.

The safety belt and the fixture according to the present invention have been described above using the safety belt and the fixture used thereof in the first to seventh embodiments, but the safety belt and the fixture according to the present invention are described in the above embodiment. It is not limited, and can be changed and used without changing the gist.

In the above embodiment, the fixture is attached to the tip of the rope, but if necessary, the fixture may be attached to the tip of the rope and further to the middle of the rope. Further, in the above embodiment, the pillar safety belt is shown as the safety belt, but the safety belt according to the present invention can also be applied to a safety belt for single fishing and a safety belt for both single fishing and U-shaped fishing. , In addition to the body belt type safety belt, it can also be applied to the harness type safety belt.

As described above, a preferred embodiment has been described with reference to the drawings, but those skilled in the art will easily assume various changes and modifications within a self-evident range by looking at the present specification. Therefore, such changes and amendments are construed as being within the scope of the invention as defined by the claims.
