Description

[Detailed description of the invention] This invention is a suspended ceiling in which a ceiling material is placed on the horizontal piece of a ceiling hanging bracket with an inverted T-shaped cross section, and lighting fixtures, partition rails, signage boards, etc. are hung on the ceiling hanging bracket. This relates to a structure that is equipped with a hanging tool for lowering it.

Conventionally, as shown in Fig. 1, a structure for attaching a hanging device to such a suspended ceiling has U-shaped holes at two diagonal corners of the long sides of a rectangular plate 4 with a hanging device 3 fixed at the center of the lower surface. What is used is one in which a letter-shaped folded portion 5 is formed and engaging pieces 8 having spring properties are provided at the other two corners. However, when installing such a hanging tool, insert the horizontal piece 2 of the ceiling hanging fitting 1 between the two U-shaped folded parts 5, and press down the engaging piece 8 having spring properties while lowering the square plate 4.
By rotating the engaging piece 8, the engaging piece 8 is fitted onto the horizontal piece 2 as shown in FIG. There was a drawback that the lower surface of the horizontal piece 2 of 1 could be scratched by rubbing. Furthermore, since the engaging piece 8 is fitted onto the horizontal piece 2, it is difficult to remove it. The present invention aims to eliminate such drawbacks of the conventional example.

The configuration of the present invention will be described below with reference to the illustrated embodiment. As shown in FIGS. 2 to 6, a ceiling hanging bracket 1 having an inverted T-shaped cross section is attached to the lower surface of a horizontal piece 2, and a hanging tool 3 is attached to the center of the lower surface. The short side of the fixed square plate 4 is formed to be approximately equal to the width of the horizontal piece 2, and
A U-shaped folded part 5 for fitting with the horizontal piece 2 is formed at two diagonal corners of the long side, and the folded part 5
An upright piece 6 is formed by bending the tip end of the ceiling member 7 upward, and the end face of a ceiling material 7 placed on the horizontal piece 2 of the ceiling suspension fitting is brought into contact with the upright piece 6. . FIG. 2 shows a lighting fixture 9 suspended from a hanging fixture 3 attached to a horizontal piece 2 of a ceiling hanging fixture on which a ceiling material 7 is placed, and FIG. The appearance of a square plate 4 for mounting is shown. As shown in the figure, U-shaped folded portions 5 provided at two diagonal corners of the long side of the square plate 4,
The portions 5 facing each other are cut diagonally so that the horizontal piece 2 of the ceiling hanger can be easily inserted. Next, FIG. 4 shows how the rectangular plate 4 equipped with such a hanging tool 3 is attached to the horizontal piece 2 of the ceiling hanging fitting. After inserting the horizontal piece 2 of the ceiling hanger 1 between the two, the U-shaped folded portion 5 is fitted onto the horizontal piece 2 by rotating the square plate 4 in the direction of the arrow. By the way, in this state, if the rectangular plate 4 rotates in the opposite direction to the arrow, it will come off the horizontal piece 2.
As shown in the figure, an upright piece 6 provided at the tip of the U-shaped folded portion 5 is brought into contact with the end surface of a ceiling material 7 placed on the horizontal piece 2. In this way, the U-shaped bent piece 5 is pressed down by the weight of the ceiling material 7, and the upright piece 7 comes into contact with the end face of the ceiling material 7, thereby stopping the rotation of the square plate 4. .

As described above, in the present invention, a U-shaped folded part is formed at two diagonal corners of the long side of a rectangular plate with a hanger disposed in the center of the lower surface, and the tip of the folded part is folded upward. Since the structure is such that the upright piece is bent and the end face of the ceiling material is brought into contact with the upright piece, the ceiling material can be used to prevent the hanger from rotating, resulting in a very simple structure. It has the advantage that it does not come off easily due to vibration etc., even though it uses a ceiling hanger, and it also has the advantage that the ceiling hanger can be attached without damaging the ceiling hanger because there is no engagement piece like in the conventional example. Therefore, there is an advantage that the hanging fixture can be easily attached and detached by simply removing the ceiling material.
