Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a lighting fixture suspended by a wire.

Prior Art The connection between the wire and the lighting fixture in a conventional wire hanging lighting fixture is as shown in Fig. 5.
A hanging part 21 formed at the lower end of the wire 20 is located between two L-shaped standing pieces 23 and 24 fixed to the upper surface of a plate 22 forming a part of the lighting equipment, A half-screw 25 passed through the upright piece 24 and screwed into the upright piece 23 is suspended. In such a configuration, since the half-screw 25 is supported at two locations, the half-screw 25 can be firmly attached, so there is no need to worry about deformation of the half-screw 25.

On the other hand, in consideration of cost reduction, space factor, etc., it is necessary to screw and fix the half-screw 25 to a single upright piece 26 formed upward from the plate body 22, as shown in FIG. 6, for example. By design, it may be necessary to do something that should not be done.

Problem to be Solved by the Invention In such a case, there is a risk that the half-screw 25, which has a structure in which tightening and fixing is completed by screwing halfway through the body, may deform during use, as shown in FIG. In the worst case, the lighting fixture may fall due to the half screw 25 breaking. The reason why the half screw 25 is used is to prevent the hanging part 21 from being damaged by tightening and to naturally maintain the verticality of the hanging part 21 during use.

The purpose of the present invention is to substantially prevent the deformation of the half-screw when the wire suspension part suspends the half-screw, thereby preventing the worst case of the lighting equipment falling. .

Means for Solving the Problems The present invention includes a plate that constitutes a part of a lighting fixture;
A hanging piece formed to hang down from this plate, a hanging part of the lower end of the wire passing through a hole formed in the plate above the side surface of this hanging piece, and a hanging part passing through the hanging part. and a half screw screwed laterally into the hanging piece, and the edge of the hole is located close to above the head of the half screw.

Function According to the present invention, the half-screw held by the hanging portion of the wire is screwed and fixed to a hanging piece formed to hang down from a plate that constitutes a part of the lighting equipment. Because of this, this hanging piece can be constructed at a lower cost than the conventional two standing pieces, has a good space factor, and has a half-thread on the edge of the hole formed in the plate. Due to the close proximity of the upper portion of the head, upward deformation of this half-thread is substantially prevented by the edge.

Embodiment Next, an embodiment of the present invention will be described with reference to FIGS. 1 to 4.

The upper end of the wire 1 is attached to, for example, an elevator (not shown) attached to a ceiling surface, and a hanging portion 2 is formed at the lower end. The hanging part 2 has a hanging tool 3 which folds back the lower end of the wire 1 into a ring shape 1a and fixes the folded end by caulking, for example. A hanging piece 5 formed to hang down from a sub-chassis 10 (plate body) constituting a part of the lighting fixture 4 has a half-screw 6 screwed in the horizontal direction, and the half-screw 6 is a hanging tool. 3 through the hole 3a of the wire 1 and the ring-shaped portion 1a of the wire 1, the hanging portion 2 suspends the half-screw 6. The half screw 6 is also passed through a washer 7 located between the head 8 of the half screw 6 and the hanging portion 2. Above the head 8 of the half-screw 6, there is a space slightly apart from the half-screw 6.
The hanging piece 5 is configured to substantially restrict upward deformation.
The edge 9 of the hole 11 formed in the sub-chassis 10 is located close to the upper side of the sub-chassis. In this embodiment, the hanging piece 5 and the edge 9 are formed from one substantially U-shaped sub-chassis 10,
A hanging piece 5 is cut downward from the upper surface of the sub-chassis 10, and the edge 9 has a hole 11 formed by the cut-up.
It is constructed as a part located at the edge of the hole. The hanging portion 2 at the lower end of the wire 1 is passed through the hole 11. The lower end of the sub-chassis 10 is attached to the bottom surface of a bottomed cylindrical chassis 12 with screws etc., and the upper end of the chassis 12 is attached to the top plate 13 of the shade 13.
It is attached to a with screws etc. The wire 1 and curl cord 14 are passed through a cylindrical cord guide 15 attached to the top plate 13a, and
It enters the chassis 12 through a. A socket 16 is attached to the lower surface of the chassis 12 with a nut or the like, and a lamp 17 is attached to the socket 16. A lifting/lowering operating tool 18 of the lighting fixture 4 is attached to the shade 13.

According to the above-described configuration, even if an excessive load is applied to the lighting fixture 4 and a force that deforms the half-screw 6 is applied, the head 8 comes into contact with the lower surface of the edge 9, so that the half-screw 6 is not deformed. Substantial deformation can be restricted, thereby preventing the lighting fixture 4 from falling due to breakage of the half-screw 6.

Note that the upper edge of the washer 7 is slightly inserted into the hole 11, so the movement of the washer 7 is limited to the hole 1.
1, there is little risk that the ring-shaped portion 1a of the wire 1 will rub against the hole edge of the hole 11, and there is little risk that the wire 1 will be cut.

Effects of the invention According to the invention, the half-screw held by the hanging part of the wire is screwed and fixed to a hanging piece formed to hang down from a plate that constitutes a part of the lighting equipment. Therefore, this hanging piece can be constructed at a lower cost than the conventional two standing pieces, has a good space factor, and has a half-screw on the edge of the hole formed in the plate. Since the upper part of the head is positioned close to the upper part of the half screw, the upward deformation of the half screw is substantially prevented by the edge, which has the effect of preventing the lighting fixture from falling due to breakage of the half screw. .
