Description

[Detailed Description of the Invention] "Purpose of the Invention" (Field of Industrial Application) The present invention relates to a lighting fixture that is embedded in a wall surface such as a building frame.

(Conventional wall-mounted lighting fixture and its solution) FIG. 4 is a perspective view showing a conventional lighting fixture 2 mounted on a wall 1. The lighting fixture 2 has a socket portion 2b that holds a lighting fixture (not shown) such as an incandescent bulb fixed to the front side of the wall surface 1,
A truncated cone-shaped globe 2a is further attached to the front side of the socket portion 2b. Therefore, the wall surface 1 was finished so that it seemed to protrude greatly toward the front of the wall surface 1.

Conventionally, lighting fixtures that have come to be attached to the wall surface 1 have generally had a structure similar to that described above. That is, even though the outer shape of the glove may vary, such as box-like, disk-like, or spherical, the feeling that the glove protrudes toward the front side of the wall surface 1 is unavoidable. Therefore, in rooms where there is not much room for indoor space, such as toilet rooms, bathrooms, washrooms, etc., the protrusion of the lighting fixture 2 makes the indoor space feel even smaller. . Furthermore, in cases where the wall surface 1 is finished with tiles or the like to give a natural stone look, the presence of the lighting fixture 2 itself sometimes destroys the warm feel of the surrounding area.

The present invention was developed in view of the above-mentioned circumstances, and is intended to prevent the indoor space from feeling smaller than it actually is by installing lighting equipment, and to prevent the lighting equipment from making the interior space feel smaller than it actually is. It is an object of the present invention to provide a new recessed lighting fixture that is designed to harmonize well with the appearance of the interior of the building.

``Structure of the invention'' (Means for solving the problem) The gist of the proposed lighting fixture is that it is a box that is embedded in the wall surface of a building frame, etc., and that it is possible to enter and exit the box by facing the front direction of the wall surface. a depth adjustment plate housed in the depth adjustment plate; a socket portion for a lighting fixture fixed to the front portion of the depth adjustment plate; a frame portion made of wall material provided around the socket portion; and the frame portion. or a glove to be attached to the socket part, and a mounting leg protruding from the bottom of the socket part facing the depth adjustment plate, and a tapping screw corresponding to the tip of the mounting leg. The point is that an insertion hole is drilled for the purpose.

(Function) When storing the depth adjusting plate in a box embedded in a wall surface, the degree of parallelism of the depth adjusting plate with respect to the wall surface and the degree of going in and out can be adjusted.
In addition, when fixing the socket section to the depth adjustment plate, the alignment of the frame section provided around the socket section must be adjusted with respect to the wall material such as tiles that are pasted on the wall surface. can do. The work of storing the depth adjustment plate in the box as well as the work of fixing the socket portion to the depth adjustment plate can all be performed from the front side of the wall surface. That is, in the socket part, the insertion hole for the tapping screw formed in the bottom part corresponds exactly to the leg end part of the mounting leg provided in the socket part. Therefore, a screw pilot hole corresponding to the leg tip of the mounting leg is drilled in the depth adjustment plate, or a tapping screw is screwed into the screw pilot hole through the leg tip of the mounting leg. It is something that can be deeply immersed.

(Example) Hereinafter, the present invention will be explained based on the drawings showing the example.

As shown in FIG. 2, the lighting device of the present invention is constructed so that a box 3, a depth adjustment plate 4, a socket portion 5, a frame portion 6, and a globe 7 are connected to each other. A lighting device 8 such as an incandescent bulb is housed and held in the socket portion 5.

The box 3 is a substantially square box and is made of metal, resin, or the like. As shown in FIG. 1, the box 3 is embedded inside the wall surface 1 so as to extend into the backing layer 1a thereof. If the planar size of the box 3 is approximately the same as the tile 9 used as a wall material, positioning when embedding it in a wall becomes easier.

As shown in FIG. 2, the depth adjusting plate 4 is a plate body formed to be slightly smaller than the opening width of the box 3, and its front portion is located at the wall surface with respect to the inside of the box 3. (See Figure 1). Near a pair of diagonal positions on the depth adjustment plate 4, there are mounting stays 4a,
4a is bent. The mounting scale 4a
is for making the positioning of the depth adjusting plate 4 adjustable and fixed with respect to the box 3, and a long hole 4b extending in the front-rear direction of the wall surface 1 is bored in the center thereof. It is set up. On the other hand, the box 3 has the elongated hole 4b of the depth adjusting plate 4.

The socket portion 5 and the frame portion 6 will be explained based on FIG. 1. The socket portion 5 is made up of an inner ring portion 5a and an outer ring portion 5b that are fitted into each other, and the frame material 6 is held between the peripheral portions of both ring portions 5a, 5b. The outer ring portion 5b has a closed bottom portion facing the depth adjusting plate 4, and a bulging portion 5c facing the depth adjusting plate 4 is formed in the center of the closed bottom portion. The bulb socket 12 for holding the lighting fixture 8 is attached inside the bulge 5c. In addition, the inner ring portion 5
A has a central opening corresponding to the bulging portion 5c of the outer ring portion 5b, and the light bulb socket 12 projects into this central opening.
The inner ring part 5a and the outer ring part 5b are connected to each other by male and female screw fitting on their inner and outer circumferential surfaces, or by connecting them at appropriate positions with screws, etc., although illustration is omitted. .

The frame part 6 is made of the same material as the tile 9 attached to the wall surface 1 and has the same outer shape as the tile 9, and the socket part 5 is located in the center of the frame part 6. It has an opening for attaching it. Further, a glove 7 attached to the socket portion 5 is provided in the opening.
(described later), a raised opening edge 6a is formed on the surface side of the opening edge 6a so as to be continuous with the radius of curvature.

By the way, the socket part 5 formed as described above
must be fixed to the front surface of the depth adjusting plate 4. However, the depth adjustment plate 4 is housed and fixed within the box 3, and the socket portion 5 also has
As described above, the frame portion 6 is attached so as to protrude around the frame portion 6. Therefore, the task of fixing them to each other while maintaining their accurate positional relationship seems to be extremely difficult based on common sense. Therefore, the following fixing structure is adopted for the proposed lighting fixture. That is, the outer ring portion 5b of the socket portion 5 has two or more, preferably about four, mounting legs 13 protruding from its closed bottom. The mounting leg 13 is formed by bending a band-shaped metal plate or the like, and is not integrally provided with the outer ring portion 5b by soldering, screwing, cutting, etc. be. A leg tip 13a is formed at the tip of the mounting leg 13 and is bent parallel to the front surface of the depth adjustment plate 4, and a tapping screw 14 can be inserted into the leg tip 13a. A hole is drilled to obtain the Further, at the closed bottom portion of the outer ring portion 5b, the leg tip portion 13 of the mounting leg 13
The tapping screw 14 is located at the position corresponding to a.
An insertion hole 15 is bored for the purpose. Further, in the inner ring portion 5a, a notch 16 (see FIG. 2) through which the tapping screw 14 can be inserted is provided at the opening edge of the central opening. After all, these notches 16, insertion holes 15 and mounting legs 13
The holes in the leg tip portion 13a are placed in a series of matching relationships with each other when facing from the front side of the socket portion 5. Therefore, the depth adjustment plate 4

Mark the hole position on the depth adjustment plate 4 through the insertion hole 15 of b and the hole of the mounting leg 13. Then, one end of the socket portion 5 is removed from the depth adjusting plate 4, and a pilot hole for the tapping screw 14 is bored in the scribed portion. After that, insert the socket part 5 again.
by applying it to a predetermined position on the depth adjusting plate 4,
Tapping screw 14 to leg tip 13a of mounting leg 13
Insert it, then screw it in. In this way, the work of fixing the socket portion 5 to the depth adjustment plate 4 may seem extremely difficult in general terms, but in the case of the lighting device of this invention, it can be done very easily and accurately. It's getting old.

The globe 7 is semi-transparent and made of glass or resin, and its outer shape is as follows:
An annular threaded part 7 is provided on the circumference of the convex lens.
It looks like a is placed around it. The glove 7
is screwed into and fixed to the inner circumferential surface of the inner ring portion 5a of the socket portion 5. Further, as described above, the radius of curvature provided on the surface side is formed to draw a curve that is substantially continuous with the raised opening edge 6a of the frame portion 6 provided around the socket portion 5.

In FIG. 2, drawn between the glove 7 and the lighting device 8 are an annular packing 17 for waterproofing and a hood 18 for providing directionality to the lighting area. As shown in FIG. 1, the hood 18 is attached to the inner ring portion 5a of the socket portion 5, and covers approximately half of the lighting device 8 (the far side in the figure). ing. Therefore, in the globe 7, light passes through only the right half in FIG. 2, and the left half remains dark. Such usage is adopted, for example, when the proposed lighting fixture is installed on the left side of the mirror body. Further, in this embodiment, as shown in FIG. 1, a band-shaped caulking pad 19 made of rubber or the like is attached to the circumference of the back surface of the frame portion 6. The caulking pad 19
When filling the space between the frame portion 6 and the surrounding tiles 9 with the joint material 20, the filling work of the joint material 20 is facilitated, and it is effective in suppressing the amount of the joint material 20 used. Become.

(Study of Alternative Embodiments) FIG. 3 is an exploded perspective view showing a situation in which a plurality of boxes 3 are connected to each other when a plurality of lighting devices of the present invention are arranged side by side. That is, the side surface of the box 3 has an insertion hole 3a for the connecting pin 21.
are bored so that the boxes 3 are connected to each other in an adjacent arrangement. However, if the distance between the lighting fixtures of this invention is wider than this, a spacer (not shown) of an appropriate thickness may be provided between the boxes 3. Moreover, the box 3 may of course be a rectangular box in which a plurality of boxes are connected in series. In the lighting device of the present invention, the lighting device 8 is not limited to an incandescent bulb, but may be a fluorescent light or the like. In this way, when a fluorescent light is used as the lighting device 8, the boxes 3,
It goes without saying that the depth adjustment plate 4, the socket part 5, the frame part 6, and the globe 7 all have different external shapes, mutual coupling structures, etc. from those in the embodiments described above. In this way, the configuration and shape of the lighting fixture of the present invention can be changed as appropriate depending on the mode of implementation.

"Effects of the Invention" As is clear from the above explanation, according to the recessed lighting fixture according to the present invention, the globe does not protrude from the wall surface, so the indoor space does not feel cramped. In other words, the interior feels spacious. Moreover, since there is no strange protrusion caused by the lighting equipment, the lighting equipment blends well with the wall surface, giving the overall appearance of the wall a calm atmosphere. In addition, in order to install the proposed lighting equipment, all of the construction work can be done from the front side of the wall, especially the fixing of the socket and depth adjustment plate, which was thought to be the most difficult task. The work can be done extremely easily and accurately. Furthermore, among these construction operations, the most time-consuming task is burying the box in the wall surface, but the positioning of the box does not require much precision. This is because the degree of parallelism of the depth adjustment plate with respect to the wall surface and the degree to which it moves in and out can be adjusted by storing the depth adjustment plate in the box. Further, by fixing the socket portion to the depth adjusting plate, the frame portion can be aligned with the wall material such as tiles attached to the wall surface. As described above, the construction work of the lighting equipment according to the present invention has many excellent advantages, such as being able to significantly shorten the overall construction time.
