  Examples of the present invention will be described below. The bolt holder of the present invention is used when a bolt is attached to an opening of a channel material using a lip groove steel, for example, when connecting a solar cell mount or a lighting fixture.

  The basic configuration of the present invention is to hold a bolt 2 on a locking body 1 having a U-shaped cross section. The locking body 1 is inserted into the channel material P through an upward opening, and is rotated 90 degrees horizontally. It is attached to the lip portion P1 (see FIGS. 4A to 4C). The locking body 1 is formed by bending a metal plate, and is formed by a top plate 10 and a pair of sandwiching plates 20 (see FIG. 1).

  The top plate 10 has an insertion hole 11 through which the bolt 2 is inserted (see FIG. 1). Moreover, the insertion part 12 formed in the width | variety narrower than between the lip parts P1 by notching the longitudinal both ends of the top plate 10 diagonally is provided (refer FIG. 5 (A)). Further, when the insertion body 12 of the locking body 1 inserted into the channel material P is pulled up above between the lip portions P1 and the locking body 1 is rotated by 90 degrees, it is locked to the upper surface of the lip portion P1. The latching | locking part 13 is formed in the longitudinal both ends of the top plate 10 (refer FIG. 5 (B)).

  On the other hand, the sandwiching plate 20 includes a head 2A of the bolt 2 inserted through the insertion hole 11 of the top plate 10 from below (see FIG. 6) and a nut 3 screwed to the bolt 2 inserted through the insertion hole 11 from above. Is a member that holds and holds the inside of the holding plate 20 (see FIG. 7).

  For this reason, a pair of locking projections 24 are provided on the inner side surface of the sandwiching plate 20 so as to lock the head 2A of the bolt 2 and the nut 3 (see FIG. 6). In the illustrated example, when the head 2A of the bolt 2 and the upper end of the nut 3 are inserted into the clamping plate 20 so as to contact the inside of the top plate 10, the head 2A of the bolt 2 and the lower end of the nut 3 are engaged. The stop protrusion 24 is locked. Further, the engaging protrusion 24 is not limited to the illustrated example, and any means for holding and holding the holding plate 20 such as one that forcibly presses the head 2A of the bolt 2 and the side surface of the nut 3 and other configurations. Can be changed.

  Further, the sandwiching plate 20 is provided with a rotation groove portion 21, a locking portion 22, and a rotation end portion 23 (see FIG. 3). The rotation groove portion 21 is a gap in which the boundary portion between the top plate 10 and the sandwich plate 20 of the sandwich plate 20 is cut out and the insertion portion 12 is rotated on the lip portion P1. And the lip | rip part P1 is inserted in this rotation groove part 21, and the latching body 1 is rotated (refer FIG. 4 (B)).

  The locking portions 22 are both longitudinal end portions of the sandwiching plate 20 that locks to the lower end of the lip portion P1 when the locking body 1 is horizontally rotated 90 degrees (see FIG. 4C). Further, a rotating end portion 23 is provided along the end portion of the locking portion 22 (see FIG. 3).

  The rotating end portion 23 is a curved surface portion of the engaging portion 22 formed with a curvature having an opening width of the lip portion P1 as a radius R (see FIG. 3). Then, when inserting into the channel material P from one locking portion 22 inclined obliquely with the bolt 2 standing and held on the locking body 1, the rotating end portion 23 of the other locking portion 22 is a lip. It is configured to be inserted while rotating along the portion P1 (see FIG. 4 (A)). In the illustrated example, a rotating end portion 23 is formed at a corner portion from the lower end portion of the plate body forming the sandwiching plate 20 to the locking portion 22. By forming at this position, the width of the locking portion 22 located below the lip portion P1 is not reduced as much as possible, and the locking strength can be increased. Moreover, it can replace with this rotation end part 23, and can also form in the shape which the latching | locking part 22 enters while rotating.

  Next, the procedure for using the present invention will be described. First, the bolt 2 is inserted into the insertion hole 11 of the main body 1, and the head 2A of the bolt 2 is held on the sandwiching plate 20 (see FIG. 1). Next, holding the bolt 2, the main body 1 is inserted obliquely from the side of the one locking portion 22 into the opening of the channel material P (see FIG. 4A). At this time, the bolt 2 side surface is inserted to a position corresponding to the lip portion P1, and the rotation end portion 23 is rotated along the lip portion P1.

After inserting the main body 1 into the channel material P, the top plate 10 of the main body 1 inserted with the insertion portion 12 of the top plate 10 aligned between the lip portions P1 is pulled up (see FIG. 5 (A)). And it sets so that the top plate 10 may become above the edge part of the lip | rip part P1 (refer FIG. 4 (B)). If it is rotated 90 degrees horizontally in this state, the locking portion 13 of the top plate 10 is locked to the upper portion of the lip portion P1 (see FIG. 5B). At this time, the locking portion 22 of the sandwiching plate 20 is locked to the lower portion of the lip portion P1 (see FIG. 4C). In the bolt 2 held in this state,
For example, various equipment such as solar cell mounts and lighting fixtures are connected.

  In addition, each structure of the top plate 10 and the clamping board 20 of this invention is not restricted to the example of illustration, The design change of the range which does not change the summary of this invention is arbitrary.

  In the embodiment of the present invention, it is described that the bolt is firmly self-supported in the upward opening of the channel material, but the direction of the opening of the channel material can be used either downward or sideways. In addition, although it is described as being attached to a channel material using lip channel steel, the application is not limited to this channel material, and the size can be changed arbitrarily if it is a similar structure, It can also be used for other purposes.
