Description

[Detailed Description of the Invention] [Technical Field of the Invention] This invention relates to a connecting fitting for orthogonally connecting two channel-shaped frame members, such as a field edge for holding a ceiling board.

[Prior art]

As the above-mentioned connecting fittings, the one shown in FIG. 3 is conventionally known. This connection fitting has square part 1
Hanging pieces 2 hanging from two opposing sides of
2, and hanging pieces 8, 8 that hang down from the other two opposing pieces, respectively. Reference numeral 6 denotes a first frame member, which includes projecting pieces 4, 4, each of which is formed by bending the upper ends of each rising side wall 14, 15, which are vertically bent on both sides of a long member, inwardly so as to approach each other. It is provided with bent pieces 5, 5 extending in the direction of the bottom surface 3 from the tips of the protruding pieces 4, 4, respectively, and is formed in a cross-sectional shape. Reference numeral 9 denotes a second frame member, which is molded into substantially the same shape as the first frame member 6 described above. The first frame member 6 is provided on both sides of the hanging pieces 2, 2.
Grooves 7, 7 through which the protruding pieces 4, 4 and bent pieces 5, 5 can be inserted are provided, respectively, and the protruding pieces 10, 10 of the first frame member 6 and the folded pieces are provided on both sides of the hanging pieces 8, 8. Grooves 12, 12 through which the curved pieces 11, 11 can be inserted are provided, respectively.

Insert the protruding pieces and bent pieces of the first frame member into the respective grooves 7, 7 of the hanging pieces 2, 2 of this connecting fitting, positioning the connecting fitting at a desired part of the first frame member,
Next, in the grooves 12, 12 of one hanging piece 8 of the connection fitting, the protruding pieces 10, 10 at the end of the second frame member 9, the bent piece 1
1 and 11, the tip 13 of the second frame member 9 faces the rising side wall 14 of the first frame member 6, and the second frame member is positioned perpendicular to the first frame member. As shown in FIG. 3, the tip of the second frame member 9 is connected to the other upright side wall of the first frame member in the same way as for the one hanging member 8 of the connection fitting. 15.

The above connection fittings are connected to the first frame member 6, the second
A gap is created between each of the frame members 9, and the groove 1
There is a drawback that the second frame member wobbles due to the play of the bent piece 11 in the gap between the two frames, and the bottom surfaces of the first frame member and the second frame member cannot be fixed on the same plane.

[Summary of the idea]

This invention consists of a base piece 16 that is in contact with the rising side wall 14 of the frame material, and a base piece 16 that extends from the edge 17 of the base piece 16 so as to come into contact with the projecting piece 4 of the frame material, and has a tip that is pulled up to the tip of the projecting piece 4 of the frame material. Locking piece 2 with hook 19
0, and a fitting piece 2 which is bent outward from the base piece 16 in the orthogonal direction and fits into the opening 23 of the second frame member 9.
4, and a screw mounting piece 26 which is bridged between the protruding pieces and has a screw 25 screwed thereto, which moves forward and backward in the direction of the protruding pieces, at a portion facing each of the protruding pieces 4, 4.
and a holding piece 28 that extends from the screw attachment piece 26 toward the bottom surface of the first frame member 6 and has projecting pieces 27, 27 at the tip thereof that extend toward the back surface of the projecting pieces 4, 4 . By adopting a configuration including the following, the above-mentioned drawbacks are eliminated.

This invention will be explained in detail below using examples.

[Example of idea]

1 and 2 are exploded perspective views showing a connecting fitting according to an embodiment of this invention, and FIG. 2 is an assembled view thereof.

This connection fitting is composed of a first metal fitting A and a second metal fitting B , and the first metal fitting A includes a base piece 16 that is in contact with the rising side wall 14 of the first frame member 6, and an upper edge of this base piece 16. 17 extends above the protrusion 4 so as to be in contact with the protrusion 4 of the first frame member 6, and the tip 1 of the protrusion 4 is attached to the tip.
a locking piece 20 having a hook 19 that is hooked on 8;
A fitting in which the base piece 16 is bent in an orthogonal direction outward from the edges 21, 21 on both sides (toward the outside of the first frame member 6) and is fitted into the opening 23 of the end portion 22 of the second frame member 9. It consists of pieces 24, 24. The second metal fitting B is the first
It is bridged between the projecting pieces 4, 4 of the frame material 6, and the projecting pieces 4, 4
a screw mounting piece 26 in which screws 25, 25 that move forward and backward in the protruding pieces 4, 4 directions are screwed onto portions opposite to each other; At the tip, protrusion 4,
4 Overhanging pieces 27, 2 extending toward the back side of each
7.

The above connection fittings are used in the following manner.
First, the openings 23 of the end portions 22 of the second frame members 9 are fitted into the fitting pieces 24 of the first metal fittings A, A , and the second frame members 9, 9 are attached. Next, the rising side walls 14, 1 of the first frame member 6
Hooks 19 of the first metal fittings A, A are hooked onto the protruding pieces 4, 4 of the 5 from above, and the respective base pieces 16 are brought into contact with the outer surfaces of the rising side walls 14, 15, respectively. Fittings A and A are attached to the first frame material 6
to be locked. Next, attach the holding piece 28 of the second metal fitting B to the first
Insert the frame material 6 into the opening between the projecting pieces 4, 4, rotate it 90 degrees horizontally, and then tighten the screws 25, 25 into the locking pieces 20, 2.
0, and the tips of the screws 25, 25 and the overhanging pieces 27, 27 lock the locking pieces 20, 20.
and hold the hooks 19, 19. No looseness occurs between the first frame member 6 and the second frame member 9 due to the tightening force of the screw 25. In addition, in the above embodiment, the first frame member 6
Two connecting fittings A are used to connect the second frame members 9, 9 to both sides of the rising pieces 14, 15, respectively, but in the case where the second frame member 9 is connected only to one of the rising pieces 14, 15. is connection fitting A
In this case, the locking piece 20 of the connecting fitting A is tightened with the screw 25 on one side of the fixing fitting B , and the projection piece 4 on the opposite side is tightened with the other screw 25, so that the fixing fitting B itself can be moved. It is best to fix it so that it does not occur.

[Effect of idea]

According to this invention, by screwing the screw of the second metal fitting, the projecting piece of the first frame member and the locking piece of the first metal fitting are overlapped and sandwiched between the screw and the overhanging piece, and the second metal fitting is screwed into the first frame member. Since the first metal fitting can be fixed without play, and the second frame member is supported by the fitting piece of the first metal fitting that extends in the longitudinal direction, the bottom surfaces of the first frame member and the second frame member can be flattened. This has the effect of being able to connect without wobbling when the tops are aligned.
