Description

[Detailed Description of the Invention] This invention relates to a reflector mounting device for a lighting fixture that is directly attached to a ceiling surface.

Conventional reflector mounting devices of this type have screw holes in the reflector, and the reflector is attached to the reflector mounting bracket, which forms part of the fixture body fixed to the ceiling surface, using mounting screws. It is something that exists.

Here, in order to bring the lamp closer to the reflector, a conical recess is formed on the center of the width of the reflector, the threaded hole is formed in the bottom of this recess, and the bottom of the recess is attached to the reflector mounting bracket. The head of the mounting screw is hidden within the recess.

The reflector mounted in this way has a slight gap between its longitudinal edges with respect to the ceiling surface, but in this conventional reflector mounting device, the reflector does not fit in the recess. Since the bottom surface and the reflector mounting bracket are only connected to each other with a small joint area, both the left and right ends are easy to move, creating an imbalance between the left and right gaps between the longitudinal edges of the reflector and the ceiling surface. , this is visible from the outside and is unsightly.

This invention was made in view of the above points, and the object thereof is to obtain a reflector mounting device for a lighting fixture with a uniform gap between the reflector and the ceiling surface from side to side and a good appearance.

This invention has a recess in which the head of a mounting screw is inserted into the reflector, and the reflector is attached to the fixture body fixed to the ceiling surface by means of the screw inserted into the recess. , the reflection plate is spaced apart from each other on both sides of the mounting portion when viewed from the longitudinal direction to maintain the appliance main body and the reflection plate parallel to each other, and to provide a gap between the periphery of the reflection plate and the ceiling surface. This is characterized by the provision of a support portion that supports the plate.

Therefore, by providing support parts on both sides of the mounting area to maintain the horizontality of the appliance body and the reflector, which are separated from each other, the gap between the reflector and the ceiling surface is uniform on both sides, and the appearance is good. It is.

A first embodiment of this invention will be explained based on FIGS. 1 and 2.

Reference numeral 1 denotes a device main body fixed to a ceiling surface 2, from which only a longitudinal mounting plate 4 having a downwardly bent edge 3 is exposed.

Socket mounting brackets 6 having a substantially U-shaped cross section are fixed to both ends of the mounting plate 4 in the longitudinal direction, and a socket 5 for holding a fluorescent lamp (not shown) is mounted thereon. A reflector mounting bracket 7 having a substantially U-shaped cross section is fixed.

A nut 9 is fixed approximately at the center of the horizontal portion 8 of the reflector mounting bracket 7 by welding or the like, and a tapped hole 10 is formed through the horizontal portion 8 and the nut 9.

Further, a support portion 11 is integrally formed from the side edge of the horizontal portion 8 and is bent downward at a predetermined width and height and has a horizontal lower edge.

These mounting plate 4, socket mounting bracket 6, and reflector mounting bracket 7 also form a part of the instrument main body 1.

Next, 12 is a flat part 13, a slope part 14, and a vertical end part 15.
It is a reflecting plate having a substantially inverted trapezoidal cross section, and is formed into a longitudinal shape so as to cover the mounting plate 4.

A socket insertion hole 16 into which the socket 5 is inserted is formed in the flat part 13 of the reflector 12, and a conical recess with a downward opening is formed at a position corresponding to the screw hole 10 of the reflector mounting bracket 7. 17 is formed.

A hole 19 is formed in the bottom 18 (upper part in the figure) of this recess 17, which corresponds to the above-mentioned hole Llo.

Note that the height of this recessed portion 17 is formed to be slightly lower than the height of the support portion 11.

And 20 is a mounting screw with a head formed with a threaded portion that fits the above-mentioned Llo.

In such a configuration, when attaching the reflector 12 to the reflector mounting fitting 7 of the instrument body 1, the socket 5 is inserted into the socket insertion hole 16 while the bottom 1 of the recess 17 is inserted.
8 is brought close to the horizontal portion 8 of the reflector mounting bracket 7.

At this time, the lower edge of the support part 11 is connected to the flat part 13 of the reflecting plate 12.
is in contact with.

Then, the hole 19 of the recess 17 is vertically aligned with the screw hole 10, and the mounting screw 20 is inserted and screwed.

The recess 17 and the support 11 have a slight difference in height by δ (not shown), but if the mounting screw 20 is firmly tightened, the difference becomes 0, and the head of the mounting screw 20 allows the bottom of the recess 17 to The reflector plate 12 is attached by pressing and fixing the lower surface of the plate 18.

At this time, a gap d is created between the ceiling surface 2 and the vertical end 15 of the reflector 12 on both the left and right sides, but the reflector 12 and the reflector mounting bracket 7 are connected at the bottom 18 of the recess 17. In addition, since the horizontal lower edge of the support portion 11 is in contact with the flat portion 13 of the reflector 12 over a predetermined width on both sides of the mounting screw 20 when viewed in the longitudinal direction, the reflector 12 is maintained horizontally. Therefore, the gap d between the ceiling surface 2 and the vertical end 15 of the reflecting plate 12 is uniform on the left and right sides, and the appearance is not impaired.

The support portion 11 also has the function of reinforcing the substantially U-shaped reflector mounting bracket 7 so that it does not deform.

Next, a second embodiment of this invention will be explained based on FIGS. 3 and 4.

The same parts as in the first embodiment are designated by the same reference numerals, and the description thereof will be omitted (the same applies to the following embodiments).

In this embodiment, a support part 21 is formed on the socket mounting fitting 6 instead of the support part 11 of the previous embodiment.

That is, this support part 21 is bent downward at a right angle with a predetermined width extending from the side edge of the horizontal part 22 of the socket mounting bracket 6 to both left and right sides of the mounting screw 20, and its lower edge is horizontal.

In such a configuration, the reflecting plate 12 is attached in the same manner as in the previous embodiment.

In this case as well, the lower edge of the support part 21 comes into contact with both left and right sides of the mounting screw 20, and the reflector 12 is maintained horizontally, thereby reducing the gap d between the ceiling surface 2 and the vertical end 15 of the reflector 12. Can be done evenly on both sides.

Further, a third embodiment of this invention will be explained based on FIGS. 5 and 6.

In this embodiment, the L-shaped metal fittings 23, which are supporting portions slightly higher than the recessed portions 17, are electrically attached to the flat portion 13 of the reflecting plate 12 on both the left and right sides of the recessed portion 17. The upper edge is made to abut on the reflector mounting bracket 7.

Even with this configuration, the left and right sides of the reflecting plate 12 can be balanced and maintained horizontally, so that the gap d with the ceiling surface can be made uniform on the left and right sides.

Next, the fourth embodiment of this invention is shown in FIGS. 7 and 8.
This will be explained based on the diagram.

In this embodiment, cut and raised pieces 24 are formed as supporting parts by being positioned on both left and right sides of the place where the recessed part 17 abuts on the horizontal part 8 of the reflector mounting bracket 7, and the cut and raised pieces 24 are bent downward at right angles. The reflective plate 12 is brought into contact with the flat portion 13 of the reflective plate 12.

Similar effects can be obtained in this case as well.

Further, a fifth embodiment of this invention will be explained based on FIG. 9.

In this embodiment, a metal fitting 25 is separately provided, which is a support portion having an N-shaped cross section and a lower opening having a lower edge that abuts along both left and right sides of the flat portion 13 of the reflection plate 12, and this metal fitting 25 is attached to the reflection plate mounting metal fitting 7. Place the mounting plate 4 in a position that will not hinder the installation of the
It has electricity attached to it.

Further, a sixth embodiment of this invention will be explained based on FIG. 10.

In this embodiment, the lengths of the edges 3 on both the left and right sides of the mounting plate 4 are made longer to form support portions 26, which are brought into contact with the slope portions 14 of the reflector 12 to maintain the horizontality of the reflector 12. be.

In this case, the same effect can be obtained, especially in the left and right support portions 2.
Since the distance between the reflectors 12 and the ceiling surface 2 is large, it is easy to make the reflection plate 12 parallel to the ceiling surface 2.

Furthermore, a seventh embodiment of this invention will be explained based on FIG. 11.

In this embodiment, a metal fitting 27 which is a cross-sectional support portion having a predetermined width is provided, and this is electrically attached to an end plate 28 in the longitudinal direction of the reflecting plate 12. One end edge of this metal fitting 27 is attached to the mounting plate 4. The reflecting plate 12 is maintained horizontally by coming into contact with the flat portion on both left and right sides of the mounting screw 20 when viewed in the longitudinal direction.

It goes without saying that this invention is not limited to these embodiments, and that various modifications can be easily devised.

In addition, in this type of reflector mounting device, vibrations occur due to a stabilizer (not shown), etc., but when this point is taken into account, it is possible to It is better to have a bearing part on the side.

In this invention, as described above, since the supporting parts are provided on both sides of the mounting screw part at a distance from each other when viewed from the longitudinal direction, the reflector can be maintained horizontally at the same time as it is attached to the reflector mounting bracket by the mounting screw. , the left and right edges of the reflector do not move up and down, and the gaps between both edges of the reflector and the ceiling surface are even on both sides, and even if the ceiling surface is distorted, there is no gap between the edges of the reflector and the periphery. In addition, the reflector is installed in a fixed position without tilting, which gives it a good appearance, and the support part is not visible from the outside, making it easy to install on the vehicle. For items that require lighting in cold conditions such as
Because the head of the mounting screw is inside the recess, the lamp can be placed close to the reflector, which allows the reflector to act as a proximal conductor to improve lamp lighting. It is effective.
