JPS5829530Y2 - Shade support device for lighting equipment - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a shade support device for a lighting fixture that suspends and supports the shade of the lighting fixture.

Shades (regardless of whether they are translucent or non-transparent) placed on the side of a lighting fixture are usually suspended by having the upper edge of the shade secured to a mounting bracket fixed to the lighting fixture body. .

- An example is shown in FIG. Reference numeral 1 denotes a lighting equipment main body with a straight tube lamp 8 attached to its lower surface, and a plurality of mounting brackets 2 are fixed at appropriate intervals in a direction perpendicular to the longitudinal direction of the lighting equipment main body 1. A locking portion 9 of the upper edge of the shade 3 is placed on the upper edge of the mounting bracket 2 provided with the above.

By the way, if the shade 3 is pushed up as it is, there is a risk that the shade 3 will come off from the restriction by the rising piece 4, so as shown in the figure, attach the presser metal fitting 10 to the mounting metal fitting 2 with the screws 11, and attach the presser metal fitting 10. It was positioned above the rising piece 4 to prevent the shade 3 from floating up.

However, when such a presser metal fitting is used, since it is a separate part from the mounting metal fitting, the presser metal fitting may be dropped or lost during installation.

In addition, the presser metal fittings are fixed by screws or caulking, making installation time-consuming.

The present invention was devised in view of these points, and its purpose is to eliminate the need for any components other than mounting brackets.
The object of the present invention is to provide a shade support device for a luminaire that allows the shade to be easily installed.

The present invention will be described in detail below based on illustrated embodiments.

FIG. 2 shows a mounting bracket 2 according to the present invention, and the lighting fixture main body 1 to which the mounting bracket 2 is fixed and the shade 3 supported by the mounting bracket 2 are the same as those shown in FIG.

This mounting bracket 2 supports the upper edges of the shades 3 on both sides of the lighting equipment main body 1 at both ends, and has a rising piece 4 formed on each edge, and a raised piece 4 from a slightly central part than the edge. A presser piece 5 is formed by cutting and raising the area.

A setting hole 6 into which a tool 12 such as a screwdriver can be inserted and engaged is provided at the base of the holding piece 5, and a narrow neck portion 7 is formed at the connection portion between the base and the mounting bracket 2.

Fold back the tip of the presser piece 5 so that it faces diagonally upward.''
It is.

FIG. 3 is a plan view of the holding piece 5 in an expanded state.

Reference numeral 13 denotes a hole through which a screw 14 is inserted when attaching the mounting bracket 2 to the lighting fixture body 1.

However, in order to attach the shade 3 using the lever mounting bracket 2, place the upper edge locking part 9 of the shade 2 on the edge of the mounting bracket 2, and then insert the tool 12 into the setting hole 6 as shown in FIG. , move the tool 12 in the direction of the arrow shown in the figure, bend the presser piece 5 by plastic deformation of the thin neck part, position the tip of the presser piece 5 above the rising piece 4 as shown in FIG. It covers the top surface of 5.

By slightly rotating the tool 12, the holding piece 5 can be bent to prevent the shade 3 from being removed.

Here, the narrow neck portion 7 is provided to avoid stress concentration due to bending and to withstand repeated use. In particular, if the holding piece 5 is bent at the setting hole 6, the position of the setting hole 6 may be damaged. The holding piece 5 and the mounting bracket 2 are connected in a curved line to prevent damage from occurring.

As described above, the present invention can prevent the shade from falling off due to floating without requiring any separate parts other than the mounting bracket.Moreover, the holding piece cut and raised from the mounting bracket prevents the snow from falling off due to the plasticity of the base of the snow. Since the tip position is changed by bending through deformation, it is possible to prevent the presser piece from getting in the way when placing the shade, and the bending to move the shade to the fixed position can be done at a slight angle. In addition, the holding piece has a setting hole so that a tool such as a screwdriver can be inserted and locked, making it easy to bend the holding piece, and furthermore, there is no space between the holding piece and the mounting bracket. Since it has a narrow neck, plastic deformation takes place at this narrow neck, which prevents damage to the setting hole, makes it easy to bend, and prevents stress concentration during deformation.
