Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a metal fitting for hanging a lattice bar for mounting a panel or the like on a ceiling.

[0002]

2. Description of the Related Art In order to suspend a lattice bar for mounting a panel or the like on an indoor ceiling from a ceiling wall, conventionally, a long hanging bolt is screwed into an anchor embedded in the ceiling wall, and the lower end of the hanging bolt is folded into a J shape. The upper end of the bent grid bar support plate is inserted and fixed with two nuts at a predetermined height and direction, and the J-shaped bent portion of the fixed grid bar support plate supports the grid bar for mounting the ceiling panel. However, by screwing the lower end of the long hanging bolt hanging down from the ceiling and the upper end of the lattice bar support plate and the two nuts, and turning the two nuts to the position of the predetermined height of the long hanging bolt. The task was not easy because it had to be raised.

Therefore, the applicant of the present invention can easily fix the fixture of the J-shaped lattice bar support plate at a predetermined height position of the hanging bolt that hangs down from the ceiling without using the nut as described above. Developed the ceiling mount fitting of Japanese Patent Application No. 2-335795. As shown in FIG. 8, a wedge locking tool C is fixed to the upper end D of a J-shaped grid bar supporting plate B that supports the ceiling panel mounting grid bar A, and this wedge locking tool C is attached from the ceiling. It is inserted from the lower end into the hanging bolt E that hangs down, the wedge locking tool C is fixed at a predetermined position of the hanging bolt E by a wedge and a wedge operation tube, and the hanging bolt E is clamped above the wedge locking tool C. The plastic pipe F for preventing looseness is provided.

[0004]

In the work of mounting the lattice bar support plate B on the suspension bolt E as described above,
After the ceiling panel mounting lattice bar A is fitted into the J-shaped bent portion of the lattice bar support plate B, the wedge locking tool C is wedged so that the hanging bolt E hangs down from the ceiling. The fixing position of the locking tool C is adjusted, and adjustment of this fixing position often requires a fine adjustment operation. This fine adjustment operation is performed by the wedge engaged with the screw on the peripheral surface of the suspension bolt E. If the screw is rotated around the suspending bolt E, the fixing position is moved up and down for each screw, so that fine adjustment can be easily performed. Since the locking tool C is fixed to the lattice bar A fitted in the J-shaped bent portion,
There is a problem that it is not possible to finely adjust the fixing position with respect to the hanging bolt E by rotating only the wedge locking tool C around the hanging bolt E. Further, the ceiling mount has a problem in that, if vertical vibration or the like occurs, the wedge of the plastic pipe F for preventing loosening is loosened or damaged, and the loosening of the wedge cannot be prevented.

The present invention solves the above problems,
It is an object of the present invention to provide a ceiling-mounting metal fitting capable of finely adjusting a fixing position with respect to a hanging bolt and reliably preventing loosening of a wedge.

[0006]

In order to achieve the above object, the ceiling mount of the present invention has two wedge-shaped locking claw plates 10 in the elongated holes 19, 19 of the lower half 18 of the tubular body 15. 10, the projecting portions 12 are fitted and engaged with each other to project the respective serrated claws 13 inside the tubular body, and the tubular body 15 and the two wedge-shaped locking claw plates 1
0 and 10 are fitted into the tapered frame body 1 and the upper half portion 16 of the tubular body is inserted.
While projecting above the top 8 of the frame body 1, the tapered back surface 11 of each wedge-shaped locking claw plate 10 faces the tapered inner surface 5 of the frame body 1, and a spring 14 is provided directly below the wedge-shaped locking claw plate 10. Is installed, the mounting plate portion 21 of the hanger 20 is fitted to the upper half portion 16 of the tubular body, and the fixing nut 25 is screwed into the screw 17 of the upper half portion 16 of the tubular body.

[0007]

The pipe 15 protruding above the taper frame 1 is inserted into the suspension bolt 26 hanging from the ceiling wall, and the fixing nut 25 is inserted.
When tightened, the pipe body 15 is pulled up, and the wedge-shaped locking claw plate 10 is also pulled up.
The taper back surface 11 is a taper inner surface 5 of the taper frame 1.
The serrated claw 13 of the wedge-shaped locking claw plate 10 is pressed by the
5 into the elongated hole 19. The saw-toothed claws 13 protruding into the tube body 15 are engaged and fixed to the threaded portions on the peripheral surface of the suspension bolt 26. In this way, the ceiling panel mounting lattice bar is fitted and supported on the hanger 20 of the ceiling hanging metal fitting attached to the hanging bolt 26 hanging from the ceiling wall. If the tightening of the fixing nut 25 is loosened, the fixing is released.

Before the fixing nut 25 is tightened, the mounting plate portion 21 of the hanger 20 is only fitted to the pipe body 15 and is not fixed to the tapered frame body 1. Therefore, the tapered frame body 1 is used as the hanger 20. Alternatively, it can be rotated around the suspension bolt 26. In order to finely adjust the fixing position of the wedge-shaped locking claw plate 10 with respect to the suspension bolt 26 after the lattice bar is once fitted in the hanger 20, the taper frame 1 is suspended from the suspension bolt before tightening the fixing nut 25. 26
By rotating the screw around the suspension bolt, the wedge engaged with the thread on the peripheral surface of the hanging bolt can be moved up and down for each thread to finely adjust the fixing position.

A wedge-shaped locking claw plate 1 which engages with the hanging bolt 26 by tightening a fixing nut 25 screwed onto the pipe body 15.
The looseness of 0 is reliably prevented.
