[0006]

EXAMPLES Examples will be described below with reference to the drawings. Figure 1
FIG. 3 is an assembled perspective view of the ceiling hanging hardware 21. The male hook member 29 has a hook portion 28 in a direction intersecting the length direction of the shaft member 27.
It is configured by sticking out.

The stopper 36 includes a shaft member 34 having a U-shaped cross section.
Is used, and racks 35 are engraved on the left and right edges. The shaft member 27 of the male hook member 29 is a sheath portion 43 having a U-shaped cross section into which the stopper 36 is fitted. The rear end 45 of the sheath portion 43 is an opening 46, and the rear end 44 of the stopper fitted in the sheath portion 43 projects from the opening 46 for a long time. Tip 41 of sheath 43 and stopper 36
The tip 42 of each of the protrusions is an upward projection, and the coil spring 39 is sandwiched between them, and the rear end 44 of the stopper 36 is biased by the coil spring 39 and protrudes from the opening 46 of the rear end 45 of the sheath 43. It is supposed to do.

The female hook member 33 is the shaft member 27 of the male hook member 29.
Sheath material 3 having a sheath portion 30 into which the length can be inserted
1, and a hook portion 32 protruding in a direction intersecting the length direction thereof.
It is composed of and. On the sheath portion 30 of the female hook member 33, a claw member 38 having a toe 37 directed in the direction in which the stopper 36 is inserted is attached at a position where it meshes with the rack 35 of the inserted stopper 36. The shaft member 27 of the male member 29 can be inserted into the sheath portion 30 through the gap 48 between the groove bottom 47 at the rear end of the groove 30 and the claw member 38.

The male hook member 29 and the stopper 36 have openings 49 and 50 formed in the bottom surfaces thereof. An elongated tongue piece 40 is cut into a part of the groove bottom 47 of the female hook 33, and a tip 51 of the tongue piece 40 is bent to form an opening 49.
It penetrates through 50 and is directed to the claw material 38, and when the tongue piece 40 is pushed in, the tip 51 pushes up the toe 37 and removes it from the rack 35.

The tip 52 of the hook portion 28 of the male hook member 29 and the tip 53 of the hook portion 32 of the female hook member 33 correspond to the shaft member 27 of the male hook member 29 and the sheath portion 32 of the female hook member 33. When they are inserted into each other, they face each other, and the H-shaped steel beam 1 is placed between them.
5 of the flanges 16 can be sandwiched.

Sheath material 3 constituting the hook portion 30 of the female hook material 33.
A bolt hole 54 is formed in the No. 1 in a direction orthogonal to the length direction. The tree receiving member 12 is attached to the lower end of the long bolt 13 inserted into the bolt hole 54. In the figure, 19 and 20 are long bolts 13 with hooks 30
11 shows a nut to be fixed to, 11 shows a splint, and 55 shows a ceiling plate.

As shown in FIG. 2, a male hook member shaft member 34 is provided.
And the stopper 36 from the gap 48 of the female hook member to the sheath portion 3
It can be pushed deep into 2. Further, as shown in FIG. 3, when the male hook member shaft member 34 is pushed deeply into the female hook member sheath portion 32, the male hook member hook portion 2 is formed.
The flange 16 of the H-shaped steel beam 15 can be held between the hook 8 and the hook portion 32 of the female hook member.

The stopper 36 is the shaft member 27 of the male hook member 29.
If it is not pushed deep enough against the stopper 3
6 to pull back the male hook member 29 from the hook portion 28 of the female hook member 33 against the resilience of the spring 39 within the range of expansion and contraction of the spring 39 interposed between the male hook member 27 and the male hook member 27. You can do it.

The length of the shaft member 34 and stopper 36 of the male hook member and the sheath member 31 of the female hook member is such that the width of the flange 16 is 9
It may be set so that the ceiling hanging hardware 21 can be attached to two types of H-shaped steel beams 15 of 0 mm and 120 mm.
As shown in the drawing, in the ceiling hanging hardware 21 of the embodiment, the groove widths of the hook portions 28 and 32 into which the flange 16 is inserted are changed stepwise, and the thickness of the flange 16 is 4.5 mm and 6.0.
It can be attached to various H-shaped steel beams 15 different from mm, 8.0 mm, 12.0 mm, ....

[0015]

Therefore, in the state where the male hook member shaft member 34 is deeply pushed into the female hook member sheath portion 32 and the flange 16 of the H-shaped steel beam 15 is gripped, the spring 39 resists the resilience. When the male hook member 29 is pulled back from the hook portion 28 of the female hook member 33, the distance between the hook portion 28 and the hook portion 32 expands by the amount of the pull back, and between the hook portions 28 and 32 and the flange 16. Since there is a gap in the space, it is possible to move and adjust the mounting position of the ceiling hanging hardware 21 to the H-shaped steel beam 15.

In this case, the claw member 38 is engaged with the rack 35 of the stopper 36, and the stopper 16 cannot be pulled out from the sheath portion 30 of the female hook member 33 as it is.

After the mounting position of the ceiling hanging hardware 21 with respect to the H-shaped steel beam 15 is adjusted in this manner, there is no space between the stopper 36 for pinching the spring 39 and the male hook member 29 so that the spring 39 can expand and contract. When the stopper 36 is pushed deep enough to reach, the tip 41 of the male hook member 29 is pushed back to the tip 42 of the stopper 36 via the spring 39 as shown in FIG. It is not possible to pull out from the female hook member sheath portion 32, and as a result,
The ceiling hanging hardware 21 is securely fixed to the H-shaped steel beam 15.

In the ceiling hanging metal fitting 21 thus closely fixed to the H-shaped steel beam 15, it is not necessary to remove it from the H-shaped steel beam 15 after the pier 11 has been installed with the ceiling plate 55, but for some reason. If you want to remove it, push the tongue 40 and push up the pawl member 38 with its tip 51 to disengage the toe 37 from the rack 35, and the stopper 3
6, the male hook member 29 can be pulled back from the sheath portion 30, the space between the hook portion 28 and the hook portion 32 is widened, and the ceiling hanging hardware 21 can be detached from the H-shaped steel beam 15.

The pressing piece (tongue piece) 40 is thus provided with the claw material 3
8 is pushed up to be removed from the rack 35, but a driver or a nail can be pushed into the openings 49 and 50 to push up the claw member 38. Therefore, the ceiling hanging hardware 2
1 is attached to the H-shaped steel beam 15, a pressing piece (tongue piece)
40 is not always required. In other words, pressing piece (tongue piece)
Reference numeral 40 is for removing the ceiling hanging hardware 21 that is erroneously attached from the H-shaped steel beam 15.

[0020]

As described above, the ceiling hanging hardware 2 according to the present invention
In the first example, the hook portion 32 of the female hook member is hooked on one end edge of the flange 16 of the H-shaped steel beam, the male hook member shaft member 29 is tapped into the female hook member sheath portion 30, and the hook portion 28 is The stopper 36 can be firmly attached to the H-shaped steel beam 15 only by a hammering operation in which the stopper 36 is further intimately contacted with the other edge of the flange 16 for further tightening.

While such a striking operation is required for about 1 second, the tightening operation of screwing the nut 26 to fix it to the flange 16 of the H-shaped steel beam 15 is 30 to 30 like the conventional ceiling hanging metal fitting. Since it takes 40 seconds, the work of attaching the ceiling hanging hardware 21 to the H-shaped steel beam 15 according to the present invention is greatly improved.
