However, when the hanging metal fitting of Patent Document 1 is to be hooked on the web side hole formed in the web instead of the flange side hole formed in the lower flange of the H-shaped steel beam, the web side hole is formed. If it is formed at a low position near the lower flange, the hanging metal fitting may not be hooked well in this web side hole. In this case, the net hanging metal fitting or the like disclosed in Patent Document 2 is used, but in this net hanging metal fitting, it is necessary to tighten the nut to the bolt penetrating the web side hole, which is a heavy work load. Further, for example, when the hanging metal fitting of Patent Document 1 is to be attached to the hole formed in the web of the channel steel girder, if the outer wall surface material is attached to the outdoor side of the channel steel girder, this outside The wall material may be an obstacle and the hanging metal fitting of Patent Document 1 may not be attached properly.

In view of the above circumstances, it is an object of the present invention to provide a hooking tool capable of hooking even when an obstacle exists in the vicinity of the hole to be hooked.

In order to solve the above-mentioned problems, the hooking tool of the present invention is formed by combining a plurality of hooking members having locking portions, and the plurality of hooking members separate the locking portions from each other to widen the locking width. It is characterized in that a hooked state is formed by the locking portion to the hole portion to be hooked.

With the above configuration, even if there is an obstacle in the vicinity of the hole to be hooked, the hooking tool can be used as long as there is a space in the back of the hole to be hooked to accommodate the locking portion. It can be hooked to the target by using the hole.

A through hole is formed in each hook member, and the through holes overlap each other in a state where the plurality of hook members are overlapped and the locking width by the locking portion is widened, and the through holes are inserted into the overlapped through holes. The member may maintain a state in which the locking width of the locking portion is widened. According to this, the state in which the hooking tool is hooked on the hooking target by using the hole portion can be easily held by inserting the member into the through hole.

A hook may be inserted into the through hole as the member. According to this, the hook can be supported by the hook, and something can be hooked by using the hook, and at the same time, the state in which the locking width by the locking portion is widened by the hook can be maintained. can.

The plurality of hooking members may be connected so as to be rotatable with each other. According to this, by the mutual rotation operation of the plurality of hooking members, the hooking operation to the hooking target and the removing operation from the hooking target can be performed, and the usability is improved.

The plurality of hooking members may be mutually rotatable by a shaft member.

Further, a state in which the locking width is widened is formed in the first rotating state, the locking width is narrowed in the second rotating state, and the locking portions of the plurality of hooking members are simultaneously inserted into the holes. A possible state may be formed.

Alternatively, in the above-mentioned hooking tool, the above-mentioned plurality of hooking members may be provided in a separated state or separable so that they can be individually inserted into the above-mentioned hole portion. Even in such a configuration, the hooking operation can be performed without any particular problem.

The shape of the plurality of hooking members may be the same. According to this, since it is not necessary to manufacture a plurality of types of punching dies and the like for manufacturing the hook member, it is possible to reduce the manufacturing cost.

In these hooking tools, the hooking target may be a structural material of the building and may be used for attaching a safety net provided in the middle of the construction of the building.

According to the present invention, even if an obstacle exists in the vicinity of the hole to be hooked, the hook can be hooked as long as there is a space in the back of the hole to be hooked to accommodate the locking portion. It can be hooked on the target using the hole.

Hereinafter, embodiments according to one aspect of the present invention will be described with reference to the accompanying drawings. As shown in FIGS. 1 (A), 1 (B), and FIG. 2, the hooking tool 1 of this embodiment is formed by superimposing two hooking members 10 on each other so as to be rotatable on each other. As the both hooking members 10, for example, members punched from a metal plate and having the same shape as each other can be used.

Each hook member 10 has a locking portion 11 on the tip end side in the longitudinal direction thereof, a push operation portion 12 in the intermediate portion, and a through hole 13 on the rear end side. Further, a connecting through portion is formed at a position on the through hole 13 side of each hook member 10 with respect to the push operation portion 12. The two stacked hooking members 10 are connected to each other so as to be rotatable by a shaft member 14 such as a rivet inserted and crimped into the connecting through portion.

The locking portion 11 has a hook-like shape bent so as to project in a direction intersecting the longitudinal direction of each hooking member 10 and in opposite directions to each other. Further, as shown in FIG. 3, the total length of each locking portion 11 is formed to be narrower than the width (diameter) of the hole portion 51 of the hooking target 5, and the two hooking members 10 are overlapped with each other. The minimum value of the overall width of the locking portion 11 in the locked state is also made narrower than the width of the hole portion 51. Further, the height of the locking portion 11 (thickness in the direction of receiving the load) is determined assuming a load load based on the use of the hook 1.

The push operation unit 12 also protrudes in a direction intersecting the longitudinal direction of each hook member 10 and in a direction opposite to each other. In this example, the push operation unit 12 has a substantially semicircular shape, but is not limited to such a shape. Then, from the state shown in FIG. 1, that is, the state in which the locking portions 11 of the two overlapped hook members 10 are separated from each other (this is referred to as the first rotation state), the push operation unit is described. 12 can be pushed to rotate both hooking members 10. As a result of this rotation, as shown in FIG. 3 (upper side), the locking portions 11 overlap each other and the overall width of the tip of the hook 1 becomes narrower, and the tip of the hook 1 becomes the hole 51. It can be inserted (this is the second rotation state).

The through holes 13 do not overlap in the second rotation state, that is, in a state where the overall width formed by both locking portions 11 is narrowed, but as shown in FIG. 3 (lower side), the first In the rotating state of 1, that is, in a state where both locking portions 11 of the hooking member 10 are separated from each other and form a substantially T-shape, they overlap each other. Further, in this state, the locking width formed by both locking portions 11 is wider than the width of the hole portion 51, and the hooking state is formed by the locking portion 11 on the hole portion 51 of the hooking target 5. It will be. In this example, the through hole 13 is not a perfect circle but a long hole long in the longitudinal direction of the hooking member 10.

In a state where the through holes 13 of the two overlapped hook members 10 overlap each other, a member such as a hook 7 can be passed through the through holes 13 as shown in FIGS. 4 and 5. Here, the hooking target 5 is, for example, as shown in FIG. 6, an eaves girder 5 made of channel steel, which is a structural material of a building (with the same reference numeral as the hooking target 5), or an H-shaped steel (not shown). A safety net (not shown) provided in the middle of the construction of the building can be attached to the hook 7 which is a beam or the like. In this case, the outer wall surface material 6 may become an obstacle 6 (with the same reference numeral as the outer wall surface material 6) when the hook 7 is directly hooked on the eaves girder 5.

With the above configuration, as shown in FIG. 3, even if an obstacle 6 exists in the vicinity of the hole 51 of the hooking target 5, the locking portion 11 is behind the hole 51 of the hooking target 5. As long as there is a space that can be accepted, the hooking tool 1 can be hooked on the hooking target 5 by using the hole 51. Further, not only in the eaves girder 5 made of channel steel, but also in the case where a hole exists on the lower side of the flange of the H-shaped steel, it is difficult to directly hook the hook 7 in the hole. The hooking tool 1 can be easily hooked.

In the above example, the through holes 13 are formed in each hook member 10, and the through holes 13 overlap each other in a state where the locking width by the locking portion 11 is widened, and the through holes 13 are inserted into the overlapped through holes 13. The member keeps the state in which the locking width by the locking portion 11 is widened. Therefore, since the hooked state to the hooking target 5 is maintained only by inserting the member into the overlapping through holes 13, it is not necessary for the hooking tool 1 to have a mechanism for holding the hooking tool 1. It is possible to reduce the cost of 1. If the through hole 13 is configured such that the hook 7 is inserted as the member, the hook 7 can be supported by the hooking tool 1, and the hook 7 can be used to hook a safety net or the like at the same time. The hook 7 can hold the state in which the locking width by the locking portion 11 is widened.

Further, when the two hooking members 10 are connected so as to be rotatable with each other, the hooking operation to the hooking target 5 and the disengagement operation from the hooking target 5 can be performed by the mutual rotation operation. Therefore, it will be easy to use. Further, if the two hooking members 10 are mutually rotatable by the shaft member 14, the usability is further improved. Further, when the hooking member 10 has the same shape, it is not necessary to manufacture a plurality of types of punching dies and the like for manufacturing the hooking member 10, so that the manufacturing cost can be reduced. Of course, the shape of the hook member 10 does not have to be the same.

Further, when the through hole 13 is a long hole long in the longitudinal direction of each hook member 10, for example, even when the cross-sectional shape of the tip portion of the hook 7 is flattened into a vertically long substantially elliptical shape. You can pass this through. Of course, the shape of the through hole 1 is not limited to such a long hole. Further, the shape of the hook 7 is not limited to that shown in the figure, and may have a shape such as a so-called carabiner.

Next, other embodiments will be described. As shown in FIGS. 7 and 8, each hooking member 10 of the hooking tool 1 of this embodiment is provided with an inclined bending portion 11a on the tip end side thereof. The locking portion 11 is formed at the tip of the inclined bending portion 11a. The inclined bending portion 11a is pushed by the edge of the hole portion 51 in the process of inserting the locking portion 11 into the hole portion 51, and automatically widens the locking width by the locking portion 11. Form a state. In the hook 1, the through hole 13 is formed in a circular shape.

Further, in these embodiments, the two hooking members 10 are mutually rotatable by the shaft member 14, but the present invention is not limited to this, and the two hooking members 10 are joined to each other by a magnet or the like. It may be rotated. The magnet may be press-fitted into the connecting through portion where the shaft member 14 is provided.

When the magnet is used, the two hooking members 10 can be detached from each other, and the two hooking members 10 can be provided in a separate state or in a separable manner. With such a structure, each hooking member 10 can be individually and sequentially inserted into the hole 51. If each hooking member 10 can be individually and sequentially inserted into the hole portion 51, the length of each locking portion 11 can be made slightly longer than the width (diameter) of the hole portion 51 of the hooking target 5. be. Then, after each hooking member 10 is individually inserted into the hole 51, they can be overlapped and connected to each other by the magnet to form a state in which the locking width by the locking portion 11 is widened. Also in this configuration, a through hole 13 is formed in each hook member 10, and a member such as a hook 7 is passed through the through hole 13 so as to maintain a state in which the locking width by the locking portion 11 is widened. May be good. Further, not limited to the magnet, each hooking member 10 can be individually inserted into the hole 51 by appropriately using an engaging means such as a screw, a string, a hook, and a ring member, and both are overlapped after the insertion. It may be possible to connect them.

Moreover, although the embodiment of the present invention has been described with reference to the drawings, the present invention is not limited to that of the illustrated embodiment. Various modifications and modifications can be made to the illustrated embodiment within the same range as the present invention or within the same range.
