FIG. 3 is a partial rear view of a wall-mounted wiring member according to an embodiment of the present invention.
In the following, a case where the wall-mounted wiring member is the lighting device 10 fixed to the wall surface 4a of the bathroom 1 will be described as an example.

A bathtub 2 and a washing place 3 are provided in the bathroom 1. A vertically long mirror 5 is provided on the wall surface 4a of the washing place 3, and a mixing faucet 6 is installed below the mirror 5. A shower head 8 is connected to the mixing faucet 6 via a shower hose 7. The shower head 8 is configured so that it can be hooked on a shower hook 9 provided on the wall surface 4a.

A lighting device 10 as an embodiment of the present invention is attached to the wall surface 4a above the mirror 5 on the wall surface 4a. As shown in FIG. 2, the lighting device 10 includes a horizontally long rectangular substrate portion 11 to which a light emitting body such as a light bulb, a fluorescent lamp, or an LED (not shown) is attached, and an illumination detachably attached to the front surface of the substrate portion 11. It has a cover 12 and is attached with the back surface 11a side of the substrate portion 11 facing the wall surface 4a.

The back surface 11a of the substrate portion 11 is formed in a flat horizontally long rectangular shape. One wiring hole 13 is opened near the center of the back surface 11a. A wiring 14 for supplying electric power to the light emitting body extends from the wiring hole 13.

Further, the back surface 11a is provided with two screw holes 15a and 15b close to the wiring hole 13 for inserting a mounting screw (not shown). The screw holes 15a and 15b are arranged along the length direction of the substrate portion 11 with the wiring holes 13 interposed therebetween. One screw hole 15a is composed of an elongated hole having a long hole diameter along the length direction of the substrate portion 11, and the other screw hole 15b is formed from an elongated hole having a long hole diameter along the width direction of the substrate portion 11. Become.

In the lighting device 10, a first protrusion 16 is integrally provided at the center of the back surface 11a of the substrate portion 11 in the length direction so as to surround the wiring holes 13 and the screw holes 15a and 15b. .. The first protrusion 16 shown in the present embodiment is composed of continuous, annular protrusions having a shape in which a rectangular protrusion 16a and an oval protrusion 16b arranged inside the rectangular protrusion 16a are combined. There is. The two screw holes 15a and 15b are arranged inside the oval-shaped protrusion 16b of the first protrusion 16.

The first protruding portion 16 is formed to be sufficiently short with respect to the length of the substrate portion 11. Therefore, when the substrate portion 11 is viewed in the length direction, the back surface 11a spreads as a flat surface one step lower than the first protrusion 16 on both ends of the first protrusion 16 protruding toward the center. ing. Nothing is provided on the back surface 11a on both ends of the first protrusion 16. The height of protrusion of the first protrusion 16 from the back surface 11a is constant.

A waterproof packing 17 made of an annular elastic material is attached to the inside of the first protrusion 16. The waterproof packing 17 is arranged along the inside of the oval-shaped protrusion 16b of the first protrusion 16 and surrounds the wiring holes 13 and the screw holes 15a and 15b.

Inside the first protrusion 16, the peripheral edge of the wiring hole 13 has a second protrusion 13a that protrudes from the back surface 11a. The height of the second protrusion 13a from the back surface 11a is the same as the height of the first protrusion 16. The shape of the wiring hole 13 is maintained by the second protrusion 13a.

Further, inside the first protrusion 16, the peripheral edges of the screw holes 15a and 15b have third protrusions 18a and 18b protruding from the back surface 11a. The height of the third protrusions 18a and 18b from the back surface 11a is the same as that of the first protrusion 16 and the second protrusion 13a. Each screw hole is formed in the third protrusions 18a and 18b. As a result, when the substrate portion 11 tightens the screw to fix it to the wall surface 4a, the periphery of the screw holes 15a and 15b is supported by the third protrusions 18a and 18b, and the substrate portion 11 does not move further toward the wall surface 4a. No. Therefore, the substrate portion 11 inside the first protrusion 16 is not deformed by the tightening torque of the screw.

The first protrusion 16, the second protrusion 13a, and the third protrusions 18a and 18b form the most protruding portion from the back surface 11a of the board portion components of the back surface 11a of the substrate portion 11. ing. That is, when the back surface 11a of the substrate portion 11 is used as a reference plane, the first protrusion 16, the second protrusion 13a, and the third protrusions 18a and 18b are formed to be the highest with respect to this reference plane. It constitutes a part. Therefore, when the back surface 11a is brought closer to the wall surface 4a in parallel so that the back surface 11a side of the lighting device 10 is in contact with the wall surface 4a, the first protrusion 16, the second protrusion 13a, and the second When the protrusions 18a and 18b of No. 3 are closer to the wall surface 4a than the back surface 11a and closer to the wall surface 4a, the substrate portion 11 first comes into contact with the wall surface 4a. At this time, the region having the first protrusion 16 as the outer frame forms a contact region that is in contact with or closest to the wall surface 4a. The back surface 11a on the outside of this contact region does not come into contact with the wall surface 4a, and is relative to the wall surface 4a rather than the end faces of the first protrusion 16, the second protrusion 13a, and the third protrusions 18a, 18b. Form a recessed non-contact area.

The board portion component is a component that constitutes the board portion 11. The board portion components of the back surface 11a of the substrate portion 11 in the present embodiment include a first protrusion 16, a second protrusion 13a, a third protrusion 18a, 18b, a wiring hole 13, and a screw hole 15a, 15b. be. The substrate portion component may be provided integrally with the substrate portion 11 or may be provided separately. However, the waterproof packing 17 is not included in the substrate component.

Next, a state in which the lighting device 10 is fixed to the wall surface 4a will be described with reference to FIGS. 4 and 5.
The lighting device 10 is screwed from the surface side of the substrate portion 11 to the wall surface 4a by two screws using the screw holes 15a and 15b. The wiring 14 is inserted through a hole (not shown) formed in the wall surface 4a.

As the screws are tightened, the wall surface 4a is gradually attracted to the substrate portion 11 side, the waterproof packing 17 is compressed, and the substrate portion 11 and the wall surface 4a come close to each other. Since the first protrusion 16, the second protrusion 13a, and the third protrusions 18a and 18b are the most protruding portions from the back surface 11a of the substrate portion 11 toward the wall surface 4a, the substrate portion 11 and the wall surface thereof. As the 4a approaches, first, the end faces of the first protrusion 16, the second protrusion 13a, and the third protrusions 18a and 18b are closer to the wall surface 4a than the back surface 11a. Then, when the screws are further tightened and the waterproof packing 17 is further compressed, the end faces of the first protrusions 16, the second protrusions 13a, and the third protrusions 18a and 18b are placed on the wall surface 4a. Upon contact, the substrate portion 11 is fixed to the wall surface 4a.

Even if the first protrusion 16, the second protrusion 13a, and the third protrusions 18a and 18b come into contact with the wall surface 4a, the back surface 11a of the substrate portion 11 outside the contact region is the first protrusion 16. Since it is a non-contact region composed of surfaces lower than the second protrusions 13a and the third protrusions 18a and 18b, it does not come into contact with the wall surface 4a. Therefore, as shown in FIG. 5, the heights of the first protrusion 16, the second protrusion 13a, and the third protrusions 18a and 18b are between the back surface 11a and the wall surface 4a of the substrate portion 11. Gap S is formed.

As described above, in the lighting device 10, except for the water-stopping packing 17 that is elastically compressed, the first protrusion 16, the second protrusion 13a, and the third protrusions 18a and 18b are from the back surface 11a. Is also fixed close to the wall surface 4a. Since the contact region having the first protrusion 16 as the outer frame is sufficiently small with respect to the area of the substrate portion 11, it is less likely to be affected by the warp of the wall surface 4a. Therefore, according to the lighting device 10, even if the wall surface 4a is warped, it can be stably and closely fixed to the wall surface 4a. Moreover, only two screws are required for mounting, and it is not necessary to increase the number of screws.

The height of the first protrusion 16, the second protrusion 13a, and the third protrusions 18a and 18b may be higher than the back surface 11a of the substrate portion 11, and is not particularly limited, but is, for example, 1 mm to 2 mm. be able to. The size of the contact region with the first protrusion 16 as the outer frame is appropriately determined depending on the size and shape of the lighting device 10, the degree of warpage of the wall surface 4a, and the like, and is not particularly limited. The maximum length of one side can be 100 mm to 120 mm.

In the present invention, the first protrusion 16 is not limited to the one formed in an annular shape, and may be formed intermittently dispersed at three or more points around the wiring hole 13. However, as shown in the present embodiment, when the first protrusion 16 is annular, the periphery of the wiring hole 13 is completely closed by the first protrusion 16, so that the wiring hole 13 can be reached. The effect of preventing the ingress of dust and water is further improved.

The waterproof packing 17 may be arranged outside the first protrusion 16. However, as shown in the present embodiment, when the waterproof packing 17 is provided inside the first protrusion 16, the outer peripheral surface of the waterproof packing 17 is supported by the first protrusion 16, so that during compression. The deformation direction of the waterproof packing 17 can be only one inner direction. As a result, the compression over the entire circumference of the water blocking packing 17 is stable, and a good water stopping effect can be exhibited for a long period of time. Moreover, since the waterproof packing 17 is shielded by the first protrusion 16, the appearance of the attachment portion of the lighting device 10 with respect to the wall surface 4a is improved.

The screw holes 15a and 15b may be arranged outside the first protrusion 16. However, it is preferable that the screw holes 15a and 15b are arranged inside the first protrusion 16 as in the lighting device 10 shown in the present embodiment. As a result, the tightening torque of the screw can be effectively applied to the first protrusion 16 from the inside of the first protrusion 16. Further, since the back surface 11a on the outer side of the first protrusion 16 is not subjected to deformation stress due to the tightening torque of the screw, the close contact state of the first protrusion 16 with respect to the wall surface 4a is more stable.

The lighting device 10 shown in the present embodiment has a stepped portion 19 along the outer peripheral edge of the back surface 11a of the substrate portion 11. When the back surface 11a of the substrate portion 11 is used as a reference plane, the step portion 19 is a portion lower than this reference plane. When the lighting device 10 has such a stepped portion 19, as shown in FIGS. 4 and 5, the shape is such that the distance between the outer peripheral edge of the back surface 11a of the substrate portion 11 and the wall surface 4a is wide. Therefore, the gap S between the back surface 11a and the wall surface 4a of the substrate portion 11 becomes relatively inconspicuous, and the appearance of the mounting portion of the lighting device 10 is further improved.

In the present invention, any one or more of the first protrusion 16, the second protrusion 13a, the third protrusion 18a, and 18b is integrally formed on the back surface 11a of the substrate portion 11. Not limited to this, it may be formed separately from the back surface 11a of the substrate portion 11 and detachably attached to the back surface 11a. According to this, the protrusions can be replaced according to the degree of warpage of the wall surface 4a, the size and shape of the lighting device 10, and the like, and the highly versatile lighting device 10 can be configured.

Further, the contact region of the substrate portion 11 with respect to the wall surface 4a is not limited to that provided at one location on the back surface 11a side of the substrate portion 11. When the illuminating device 10 is larger or longer, the same contact regions as described above may be dispersedly arranged at a plurality of locations on the back surface 11a.

In the above description, the horizontally long rectangular lighting device 10 has been illustrated, but the specific shape of the wall-mounted wiring member according to the present invention does not matter. Further, the lighting device 10 is not limited to the one fixed in the bathroom. Further, the present invention is not limited to the lighting device, and other members having a wiring extending from the back surface and having a configuration in which the back surface side is fixed to the wall surface (for example, a wall-mounted television, a wall-mounted speaker, a wall-mounted operation board, etc.) ) Is also widely applicable.
