Description

[Detailed Description of the Invention] [Technical Field] This invention relates to a lighting fixture cover for a lighting fixture embedded in the ceiling.

[Background technology]

Conventionally, a lighting equipment cover 70 as shown in FIGS. 6 and 7 has been used. The lighting equipment cover 70 includes a translucent cover 72 and a translucent cover 72.
It consists of a mounting frame 74 that supports the. Reference numeral 76 denotes a device body in which a lamp 77 is housed. 78 is a ceiling material. Such a lighting equipment cover 70 has no special processing for removal, and as shown in FIG. )
, pull down the mounting frame 74 supported by the appliance body 76 by several centimeters, push up the translucent cover 72 and remove it from the gap between the mounting frame 74 and the ceiling material 78 , and remove the mounting frame 74
The lamp 77 was being replaced and cleaned through the opening.

However, when the ceiling material 78 is made of a fragile material, there is a problem that the ceiling material 78 may be deformed or damaged by nails when the mounting frame 74 is pulled down. Also, if you carelessly push up the translucent cover 72,
There was a problem that the transparent cover 72 was damaged.

In order to solve these problems, a lighting fixture cover 80 shown in FIGS. 8 and 9 has been proposed.
This proposed example consists of a translucent cover 82 and a mounting frame 84 that supports the translucent cover 82 inside and is provided with a small window 84b having a revolving door 84a at its end. In this proposed example, the revolving door 84a provided in the small window 84b
The lighting fixture cover 80 was removed by pushing up one end to make the other end protrude (FIG. 9), inserting a finger into the small window 84b and pulling down the mounting frame 84.

However, by providing the revolving door 84a, the mounting frame 8
Since the width of 4 becomes wider, there was a problem that the appearance was spoiled.

[Purpose of invention]

The purpose of this invention is to provide a lighting fixture cover that does not deform or damage ceiling materials or translucent covers, and does not impair the appearance.

[Disclosure of invention]

The lighting equipment cover of this invention has a rectangular frame shape consisting of one side and the remaining U-shaped piece, and has a mounting frame arranged on the ceiling surface and a longitudinal end extending into the U-shaped piece. a slide rotating member having a base end attached to the one side and having a long hole extending from the base end to the distal end and forming a wide part on the distal end side of the long hole; and a slide rotating member attached to the U-shaped piece and having the wide part. a fixed shaft member having a length smaller than the width of the slot and larger than the width of the slot, the fixed shaft member having a flat shaft that slidably fits into the slot and is rotatable in the wide part; and a translucent cover placed on the mounting frame and covering the inside of the mounting frame.

According to the configuration of this invention, when the mounting frame is lowered, one side can be slid from the U-shaped piece and rotated so that it can be grasped by hand in a hanging position, and it is easy to deform or damage the ceiling or translucent cover. It can be removed without any trouble. Furthermore, since one side constitutes a part of the mounting frame, there is no need to increase the width of the mounting frame, and the appearance is not impaired. Furthermore, unless one side slides sufficiently horizontally with respect to the U-shaped piece, it will not be in a drooping state, so one side will not be inadvertently drooping.

Embodiment A first embodiment of this invention is shown in FIGS. 1 to 4. The lighting equipment cover of this embodiment includes a rectangular frame-shaped mounting frame 3 arranged on the ceiling surface, and a translucent cover 1 whose outer periphery is placed on the mounting frame 3 and covers the inside of the mounting frame 3. , the mounting frame 3 is divided into one side 4 and the remaining U-shaped piece 6, and the one side 4 is connected to the U-shaped piece 6 so as to be rotatable between a ceiling-facing position and a hanging position.

The translucent cover 1 is made of milky white acrylic resin in this embodiment.

The mounting frame 3 is formed by framing an L-shaped member into a rectangular shape, and is divided into one short side 4 and the remaining U-shaped piece 6.

As shown in FIG.
A pair of fixed shaft fittings 1 fixed to the ends of a and 6b
0, and a slide rotation fitting 12, which is a slide rotation member, fixed to the bottom plate 4a on one side 4 at a position corresponding to the fixed shaft fittings 10, which are a pair of fixed shaft members.

As shown in FIG. 3, the fixed shaft fitting 10 has a shaft 10b with an oval cross section protruding from the side surface of an inverted L-shaped piece 10a serving as a mounting portion, and a retaining piece 10c at the tip of the shaft 10b.
It has been established.

As shown in FIG. 4, the slide rotating metal fitting 12 is attached to a rising piece 12b raised from a mounting piece 12a.
An elongated hole 12c having a diameter-enlarged round hole 12d is provided at the end as a wide portion. In this case, axis 1
The minor axis a of 0b is set smaller than the width p of the elongated hole 12c. Also, the major axis b of the shaft 10b
is smaller than the diameter q of the round hole 12d and the elongated hole 1
It is set larger than the width dimension p of 2c.

The operation of this embodiment will be explained based on FIGS. 1 and 2. FIG. 1 shows a ceiling-facing attitude in which the lighting fixture cover is attached to a ceiling (not shown). From this posture, when one side 4 is slid in the direction of arrow A, the long hole 12c of the sliding rotary fitting 12 on one side 4 moves relative to the shaft 10b having an oval cross section, and when the shaft 10b reaches the round hole 12d, The slide rotary fitting 12 rotates due to its own weight on one side 4, so that one side 4 is in a hanging position (FIG. 2).

According to the lighting equipment cover of this embodiment, when the mounting frame 3 is lowered, one side 4 can be slid from the U-shaped piece 6 and rotated so that it can be grasped by hand in a hanging position. The cover can be removed without deforming or damaging it. Furthermore, since the side 4 constitutes a part of the mounting frame 3, there is no need to increase the width of the mounting frame 3.
Does not spoil the appearance. Furthermore, unless one side 4 slides sufficiently horizontally with respect to the U-shaped piece 6, it will not be in a drooping state, so that one side will not be inadvertently drooping.

In addition, in this embodiment, the slide rotating metal fitting 12
Since the translucent cover 1 is slid so that one side 4 takes a hanging position, the translucent cover 1 is attached to the pair of horizontal pieces 6a, 6.
It can be removed by sliding horizontally between b.
There is no need to pull down the entire mounting frame 3.

A second embodiment of this invention will be explained based on FIG. In the lighting equipment cover of this embodiment, the connector 8 used in the first embodiment is replaced with a connector 18 consisting of a fixed shaft bracket 20 and a slide rotation bracket 22, and the fixed shaft bracket 20 is fixed. This corresponds to the shaft fitting 10, and the slide rotating fitting 22 corresponds to the sliding rotating fitting 12. The slide rotating fitting 22 is a rising piece 22b raised from the mounting piece 22a.
A long hole 22c having a square hole 22d with an enlarged diameter as a wide portion is provided at the end. Note that the other parts have the same configuration as the first embodiment, and the same parts are given the same reference numerals and the description thereof will be omitted.

In addition, in each of the above-mentioned embodiments, one side 4 is the mounting frame 3.
Although one of the short pieces is cut into pieces, one of the long pieces may be cut into pieces.

[Effect of idea]

According to the lighting fixture cover of this invention, when pulling down the mounting frame, one side can be slid from the U-shaped piece and rotated to hold it in a hanging position, making it easy to deform the ceiling or translucent cover. It can be removed without damaging it.
Also, one side constitutes a part of the mounting frame,
There is no need to increase the width of the mounting frame, and the appearance will not be impaired. Furthermore, since the sagging state does not occur unless one side slides sufficiently horizontally with respect to the U-shaped piece, there is an effect that one side will not be inadvertently sagging.
