Description

[Detailed Description of the Invention] [Technical Field] This invention relates to a lighting equipment mounting device.

[Background technology]

Conventional examples are shown in FIGS. 6 to 10. That is, this lighting fixture mounting device forms a pair of mounting holes 52 through which the mounting plate mounting screws 51, which are wood screws, are screwed into the mounting surface 50.
A pair of device mounting screws 5 in a direction perpendicular to the line direction of
3 and a pair of tightening holes 5 through which the device mounting screws 53 are passed over the mounting plate 54.
5 and a flange 57 having a lamp 56 on the surface side, and a nut 58 that is screwed onto a fixture mounting screw 53 to tighten the flange 57.

When the mounting plate 54 is mounted on the mounting surface 50, particularly on a wall surface, it is often mounted on a switch box or outlet box buried in the wall surface, so three mounting holes 52 are formed in consideration of the dimensions. 59 is a resin insulating bushing provided in the mounting hole 52, 60 is a waterproof gasket interposed between the mounting plate 54 and the wall surface, 61 is a curled power supply hole, and 62 is a terminal block.

However, in this lighting fixture mounting device, when the flange 57 is attached to the fixture mounting screw 53, the flange 57 tilts as shown in FIG.
There was a drawback that a gap δ was formed between the two and water could seep in.

On the other hand, as shown in FIGS. 11 and 12, it is conceivable to prevent the occurrence of the gap δ by arranging both the mounting holes 52 of the mounting plate 54 and the instrument mounting screws 54 in the vertical direction.

However, since the pitch between the mounting holes 52 on one side is determined by a switch box or the like to which the mounting plate 54 is mounted, the mounting plate 54 becomes larger.
This has the disadvantage that it spoils the appearance of the device.

[Purpose of invention]

The purpose of this invention is to provide a lighting fixture mounting device that can prevent the above-mentioned gap from occurring without increasing the size of the mounting plate.

[Disclosure of invention]

The lighting equipment mounting device of this invention includes a mounting plate having a pair of mounting holes through which mounting plate mounting screws are screwed into the mounting surface, and one end of which is movable near each of the mounting holes on the surface of the mounting plate. a pair of support members that are positioned above the mounting holes when mounted and moved and have device mounting screws erected on the surface side; and a pair of tightening holes that cover the mounting plate and allow the device mounting screws to pass through; The device includes a flange having a lamp on its side, and a nut that is screwed onto the fixture mounting screw to tighten the flange.

According to the configuration of this invention, since the instrument mounting screws are provided on the support member that is movable over the mounting hole, it is possible to improve the appearance of the instrument without increasing the size of the mounting plate unlike in the past. Furthermore, since the mounting holes and the device mounting screws are arranged in the same direction, it is possible to prevent gaps from occurring due to the inclination of the flange, which is the case in the past, and water intrusion can be prevented.

Embodiment A first embodiment of this invention will be described based on FIGS. 1 to 3. That is, this lighting fixture mounting device includes a mounting plate 3 having a pair of mounting holes 2 through which mounting plate mounting screws 1 are screwed into the mounting surface;
One end is movably attached near each of the mounting holes 2 on the surface of the mounting plate 3, and when the mounting plate 3 is moved, the mounting holes 2
It has a pair of support members 6 located above and with fixture mounting screws 5 erected on the surface side, a pair of tightening holes 7 that cover the mounting plate 3 and through which the fixture mounting screws 5 are passed, and a lamp 8 mounted on the surface side. Flange 9 with
and a nut 10 that is screwed onto the instrument mounting screw 5 and tightens the flange 9.

The mounting surface (not shown) is an example of a wall surface.

The mounting plate 3 has a power supply hole 11 formed in the center and supports 12 and 13 on each side of one opposing edge.
is formed. The supports 12 and 13 are formed by forming a pair of cut lines 14 of a predetermined depth in the center of one opposing edge and bending both sides thereof. Therefore, a tongue piece 20 is formed between the support stands 12 and 13, and the pair of mounting holes 2 are formed in the tongue piece 20 at mounting plate mounting pitches. Each mounting hole 2 is an elongated hole such as an oval shape, and is oriented in directions perpendicular to each other. Furthermore, reinforcing ribs 15 are formed in parallel on the inside of one opposing edge. On the other hand, the other opposing edge of the mounting plate 3 also forms a vertically bent piece 16.

The support member 6 is a rectangular plate with a hole (not shown) formed at one end and a notch 18 at the side of the other end.
is formed, and a knob piece 19 is bent in the vicinity thereof. A fixing screw 17 is provided on each of the support stands 12 and 13, and the fixing screw 17 is passed through a hole at one end of the supporting member 6, so that the supporting member 6 can be rotated depending on the degree to which the fixing screw 17 is tightened, and a notch 18 at the other end is provided. is secured to the fixing screw 17 of the support base 13.

The proximal end of the instrument attachment screw 5 is fixed to the support member 6 by caulking.

The mounting plate mounting screws are wood screws.

The nut 10 is an embodiment of a bag nut.

The lamp 8 has a bracket 8a attached to a flange 9, and the bracket 8a is provided with a lamp main body (not shown) similar to that shown in FIG. 10, for example.

When attaching the mounting plate 3 to the mounting surface, touch the mounting plate 3 to the mounting surface via a gasket (not shown),
Loosen the fixing screw 17 and rotate the support member as shown in FIG. 2 so that the mounting hole 2 is visible. In this state, the mounting plate mounting screw 1 is passed through the mounting hole 2 and the mounting plate is mounted to a switch box or the like on the mounting surface. Next, support member 6
As shown in FIG. 3, rotate the screw so that it overlaps the mounting hole 2, and tighten the fixing screw 17 to fix it. Further, the flange 9 is placed on the flange 9, and the instrument mounting screw 5 is passed through the tightening hole 7 of the flange 9, and the nut 10 is tightened to press the edge of the flange 9 against the packing and fix it.

According to this embodiment, since the instrument mounting screws 5 are provided on the support member 6 that is movable above the mounting hole 2, the mounting plate 3 does not need to be enlarged as in the conventional case, and the appearance of the instrument can be improved. can. Furthermore, since the mounting holes 2 and the device mounting screws 5 are arranged in the same direction, it is possible to prevent gaps from occurring due to the inclination of the flange 9 as in the conventional case, and water intrusion can be prevented.

Further, in this embodiment, since the mounting hole 2 is formed in the tongue piece 20 formed by the cutting muscle 14,
Since the entire mounting plate 3 is not bent by tightening the mounting plate mounting screws 1, the pitches of the instrument mounting screws 5 do not deviate from each other. In other words, conventionally the first
As shown in Figure 3, attach the mounting plate 5 using the mounting plate mounting screws 53.
4, the mounting plate 54 is deformed as shown in the figure due to the unevenness of the mounting surface, and the mutual pitch of the instrument mounting screws 53 changes, which has the drawback that the tightening hole 55 of the flange 57 cannot be inserted. It was. Furthermore, if the inner end of the cut line 14 is extended toward the center of the mounting plate 3 beyond the support stands 12 and 13, the tongue side 20 can be tightened by tightening the mounting plate mounting screw 1.
This is even more effective since the bending of the mounting plate 3 is less likely to affect the entire mounting plate 3. Further reinforcement rib 1
5 can reliably prevent the mounting plate 3 from being deformed.

In addition, since the support member 6 is supported on the support stands 12 and 13 and a gap 4 is formed between the support member 6 and the mounting hole 2, the instrument attachment screw 5 can be attached to the support stands 12 and 13 compared to the conventional case.
It is possible to reduce the variation in the pitch between the tips of the screws due to the inclination that occurs when the instrument mounting screw 5 is caulked and fixed to the support member 6. In other words, the device installation screw 5
If it is long, the pitch between the ends of the instrument mounting screws 5 will vary widely due to the inclination when caulking and fixing them to the mounting plate 3, making it impossible to pass through the tightening hole 7 of the flange 9.

A second embodiment of this invention is shown in FIG. That is, in this lighting fixture mounting device, the rotation centers of the support members 6 are located on opposite sides, and the support members 6 rotate in mutually opposite directions as shown by the arrows, and the other parts are arranged in the first direction. This is similar to the embodiment.

In addition, as a modification, the support member 6 may have a shape as shown in FIG. 5, and the support stands 12 and 13 may be omitted. In addition, the tip side of the support member 6 was also fixed with the fixing screw 17, but the fixing screw 17 on the rotation center side
It may be omitted if sufficient strength can be obtained.
Further, the support member 6 may be provided on the mounting plate 3 so as to be linearly movable instead of being rotationally movable, and in short, it is sufficient if it is movably provided.
