Description

  The present invention relates to an indirect lighting device and a bathroom unit including the indirect lighting device.

  Indirect lighting can give a soft impression overall by applying light emitted from a light source such as an incandescent bulb or fluorescent tube to a wall surface etc. and illuminating the surrounding area with the soft reflected light. It is said that it is used in a relaxing space such as a lighting in a train car or a living room of a house (see Patent Document 1, Patent Document 2, etc.).

In such a conventional indirect lighting device, a reflector (reflector) or a cover that covers the lighting device body is provided on the front surface of the incandescent bulb or the fluorescent tube, and is fixed to the wall surface or the lighting device body with screws or the like.
Therefore, when replacing the incandescent bulb or fluorescent tube, remove the fixing of the reflector or cover as described above by removing the screws, replace the incandescent bulb or fluorescent tube, and then replace the reflector or cover with the screw again. It must be fixed and is very troublesome.

  Therefore, the inventor of the present invention has a rod-like fluorescent tube, and the lighting fixture main body attached to the wall surface with the longitudinal direction of the fluorescent tube oriented in the horizontal direction; In an indirect lighting fixture having a reflector provided toward the wall side, the reflector is rotated about an axis parallel to the central axis of the fluorescent tube via a hinge, and a reflection position that blocks direct light of the fluorescent tube Therefore, it was considered that the fluorescent tube could be easily replaced if the position of the fluorescent tube could be changed.

  By the way, when an indirect lighting fixture is installed at a high place on the bathroom wall surface, it is necessary to change the fluorescent tube while standing on a chair, a stepladder, a washbasin or a bathtub tub, etc. Since the place where the feet are placed is small, it is easy to break the balance, and it is possible to break the balance and hold the reflector with your hand to support the body.

However, in the case of indirect lighting fixtures with the above-mentioned structure, if the length of the indirect lighting equipment is supported by supporting the body weight, the reflector may bend and deform, be damaged, or fall off. I found out that
Therefore, it is conceivable that the reflector is made of a rigid body that is difficult to bend. However, the weight is increased and the strength of the hinge portion and the like must be increased, resulting in a problem of excessive costs.

Japanese Utility Model Publication No. 5-65678 JP 2004-349165 A

  In view of the above circumstances, the present invention can reduce the weight of the reflector itself without making the strength of the reflector so high, and the safety provided with the indirect lighting device and the indirect lighting device that is difficult to bend and damage the reflector portion even when a load is applied. The purpose is to provide a high bathroom unit.

  In order to achieve the above object, an indirect lighting apparatus according to claim 1 (hereinafter referred to as “indirect lighting apparatus of claim 1”) according to the present invention has a rod-shaped fluorescent tube, and A lighting fixture main body that is mounted on the wall surface with the longitudinal direction being horizontal, and is arranged in parallel to the fluorescent tube, and rotates about an axis parallel to the central axis of the fluorescent tube to direct light from the fluorescent tube as indirect illumination. The reflector position to be blocked and the fluorescent tube replacement position when the fluorescent tube is replaced so that the position can be changed, so that the wall faces the intermediate position on the upper edge side of the reflector. A locking bracket that is fixed, and a receiving bracket that is fixed to the wall surface and receives the load applied to the reflector by locking the locking bracket when the reflector comes to a reflection position that blocks direct light from the fluorescent tube. And an indirect lighting fixture comprising The locking bracket includes a fixing portion fixed to the reflector body, and an engagement portion extending from the fixing portion to the wall surface side and having a through hole, and the receiving bracket connects the reflector to the fluorescent tube replacement position. When the lens is rotated to a reflection position that blocks direct light from the fluorescent tube, a guide portion that enters the through-hole during rotation and guides the engaging portion to the receiving position is provided.

  The indirect lighting device according to claim 2 according to the present invention (hereinafter referred to as "lighting device according to claim 2") is the indirect lighting device according to claim 1, wherein the guide portion of the metal fitting is a straight line with the wall surface fixed. And a bending guide portion that is bent obliquely upward in the wall surface direction from the upper end of the rising guide portion.

  The indirect lighting fixture according to claim 3 according to the present invention (hereinafter referred to as "indirect lighting fixture of claim 3") is the indirect lighting fixture according to claim 1 or 2, wherein the reflector is continuous in the longitudinal direction. It is characterized by comprising a resin-made reflector main body having a hollow portion and a light metal reinforcing material inserted into the hollow portion of the reflector main body to reinforce the reflector main body.

  The bathroom unit according to the present invention is characterized in that the indirect lighting device of the present invention is attached to a wall surface.

In the present invention, the reflector is not particularly limited, but is a reflector body made of a synthetic resin molded product such as polyester, polycarbonate, polymethacrylate, etc., and the reflector body reinforced with a lightweight metal reinforcing material such as aluminum or an alloy thereof. Is preferred.
In addition, the method of attaching the reinforcing material is not particularly limited. However, in consideration of safety, the reflector main body is provided with a hollow portion continuous in the longitudinal direction as in claim 3, and is inserted into the hollow portion. It is preferable that the reinforcing material is fixed to the reflector body so that the reinforcing material is not exposed to the outside as much as possible.

  The material of the receiving metal fitting and the locking metal fitting is not particularly limited as long as it can withstand the load applied to the reflector. For example, a material obtained by bending a plate material such as stainless steel or chrome plating steel is preferable.

  The indirect lighting apparatus according to claim 1 of the present invention has a rod-shaped fluorescent tube, and the fluorescent tube is mounted in parallel with the fluorescent tube, the lighting device main body being attached to the wall surface with the longitudinal direction thereof forming a horizontal direction. Rotating about an axis parallel to the central axis of the fluorescent tube so that the reflection position for blocking the direct light of the fluorescent tube as indirect illumination and the fluorescent tube replacement position when replacing the fluorescent tube can be changed. The reflector is supported by the hinge, the locking bracket fixed to the intermediate position on the upper edge side of the reflector so as to face the wall surface, and fixed to the wall surface, and the reflector blocks the direct light of the fluorescent tube An indirect lighting fixture comprising: a receiving bracket that locks the locking bracket when it comes to a reflection position and receives a load applied to the reflector, wherein the locking bracket is fixed to the reflector body And from the fixed part to the wall And the engagement portion having a through hole, and when the reflector rotates the reflector from the fluorescent tube replacement position to a reflective position that blocks direct light from the fluorescent tube, the through hole is being rotated. Since the guide part that enters and guides the engaging part to the receiving position is provided, the load applied to the reflector can be received by the wall surface via the locking bracket and the receiving bracket, and the reflector bends even if the load is applied to the reflector. Accidents such as breakage or falling can be prevented. Moreover, the locking metal fitting is easily and reliably engaged with the receiving metal fitting only by rotating the reflector from the exchangeable position to the reflection position by the guide portion. Therefore, the strength of the reflector itself can be reduced without making it very high.

As in the indirect lighting apparatus according to claim 2, the guide part of the metal fitting is a rising guide part that rises linearly in a fixed state on the wall surface, and a bent part that is bent obliquely upward in the wall surface direction from the upper end of the rising guide part. The reflector is made fluorescent by fixing the receiving bracket to the wall so that the tip of the bending guide portion is arranged on the rotation locus of the through hole of the locking bracket attached to the reflector. When rotating from the tube replacement position to the reflection position, the bending guide tip smoothly enters the through hole. On the other hand, since the rising guide portion is arranged so as to enter the center direction of the rotation locus from the rotation locus of the through hole, when further rotated, the peripheral wall surface of the through hole once hits the rising guide portion and the longitudinal direction of the reflector The central part is elastically deformed in the center direction of the rotation locus. Then, the reflector is further rotated to the reflection position, and the engaging portion is received at the receiving position of the receiving metal fitting.
Therefore, for example, when the head or the like hits the reflector and the reflector bounces up slightly, the reflector does not jump up to the replacement position and returns to the original reflection position. That is, the rising guide portion applies a load due to the middle portion in the longitudinal direction of the reflector being bent inward, and the locking bracket is prevented from jumping upwards over the rising guide portion. That is, the reflector can be held in a stable state at the reflection position.

  Further, as in the indirect lighting apparatus of claim 3, the reflector is a resin-made reflector main body having a hollow portion that is continuous in the longitudinal direction, and a light weight that is inserted into the hollow portion of the reflector main body to reinforce the reflector main body. If it is provided with a reinforcing material made of a metal material, the reflector can be reduced in weight, and the reinforcing material is not exposed to the outside, so that there is no accident that the hand is injured by the reinforcing material.

  In the bathroom unit of the present invention, since the indirect lighting device of the present invention is attached to the wall surface, the interior of the bathroom can be illuminated with soft light to make a relaxing space and the fluorescent tube can be replaced safely. You can do it.

Hereinafter, the present invention will be described in detail with reference to the drawings showing embodiments thereof.

While hitting the end wall surface, the stopper 66b rotates about the shaft 63 until it hits a part of the peripheral wall of the bearing portion 62.

As shown in FIGS. 4 and 5, the decorative member 7 is a resin extrusion-molded product, the longitudinal dimension is substantially the same as the longitudinal dimension of the reflector 3, and the wall surface fixing portion 71, the decorative portion, 72.
The decorative portion 72 is connected to the wall surface fixing portion 71 via the connecting portion 73, and the decorative surface makes an angle of approximately 45 degrees downward with respect to the floor surface in a state where the wall surface fixing portion 71 is fixed to the wall surface W. Are arranged as follows.

  In this indirect lighting device 1, the lighting device main body 2 is attached to the wall surface W, and the reflector 3 is attached to the wall surface W by the two support arms 6, as shown in FIG. 5, the fluorescent tube L in which the reflecting surface 3a of the reflector 3 faces the floor surface. , And the fluorescent tube L supported by the luminaire main body 2 is not directly visible from the indoor side as shown in FIG. 4, and the reflecting surface 3a is the ceiling. It is attached to the wall surface W so as to rotate between the reflection position where the angle formed by the reflection surface 3a and the ceiling T is approximately 45 degrees, facing the corner portion of T and the wall surface W.

At this time, the metal fitting 5 is locked even if the reflector 3 is bent toward the ceiling T as shown in FIG. 13 (a) while the reflector 3 is rotating from the replacement position of the fluorescent tube L to the reflection position. The distal end portion of the bent portion 44 of the metal fitting 4 is in contact with the distal end portion of the inclined guide portion 53 of the receiving metal fitting 5, and the guide portion 5 b is fixed to the wall surface W so as to fit into one of the through holes 43.
Then, the decorative member 7 is fixed to a position where the luminaire main body 2 cannot be seen from the indoor side by the reflector 3 and the decorative portion 72 in a state where the reflector 3 has reached the reflection position.

The indirect lighting fixture 1 is as described above. As shown in FIG. 5, the fluorescent lamp L rotates the reflector 3 to the ceiling T side up to the replacement position of the fluorescent lamp L to place the lighting fixture main body 2 in the chamber. It can be easily exchanged so that it can be seen from the inside.
When the exchange is completed, as shown in FIG. 4, the original indirect illumination can be performed by rotating the reflector 3 to the floor side to the reflection position.

The reflector 3 is at the reflection position, and the central portion of the reflector 3 is locked to the receiving metal fitting 5, and the load applied to the reflector 3 from above at the central portion of the reflector 3 is increased by the engaging metal fitting 4 and the receiving metal fitting 5. It can be received by the wall surface W via.
Therefore, even if the posture is lost during maintenance such as replacement of the fluorescent tube L and the reflector 3 is gripped, the reflector 3 is not greatly bent or damaged, and is safe.

  Further, even when the reflector 3 is bent to the ceiling side when the reflector 3 is returned from the exchange position to the reflection position, the bent portion is formed on the distal end portion of the bending guide portion 55 of the receiving metal fitting 5 and the locking metal fitting 4 side. 44, the guide part 5b of the metal fitting 5 is guided to the through hole 43 by the inclination of the bent guide part 55 and the bent part 44, and a predetermined engagement state is obtained. It is done. Of course, as shown in FIG. 13 (b), even if the reflector 3 is bent toward the fluorescent tube L, the guide portion 5b of the metal fitting 5 is well guided to the through hole 43, and a predetermined engagement state is obtained.

Moreover, since the reinforcing material 33 is accommodated in the reflector body 31, the indirect lighting device 1 has better design and safety than those in which a reinforcing material such as an angle is attached to the outer wall surface of the reflector body 31. It is.
That is, when the reinforcing material is attached to the outer wall surface of the reflector body 31, there is a risk that the hand touches the reinforcing material when rotating the reflector 3, and the hand may be damaged. The material 33 is safe because it does not touch the hand directly.

  Moreover, since the latching metal fitting 4 is provided with two through-holes 43 symmetrically across the central axis, it can be used for bathroom units having different specifications. That is, the support arm 6 and the metal fitting 5 are usually screwed to a column (stud) that supports the wall panel. However, if the specifications are different, the positions of the columns and the pitch between the columns are different. However, since the mounting position of the receiving metal fitting 5 is the central portion, the position cannot be moved left and right, and the reflector 3 must be fixed by swinging left and right. Therefore, by providing the two through holes 43, the metal fitting 5 can be engaged with any one of the through holes 43 even if the reflector 3 is mounted by swinging left or right, so that versatility is enhanced.

Furthermore, since the receiving metal fitting 5 is provided with the rising guide part 54 that rises linearly in a fixed state on the wall surface and the bending guide part 55 that is bent obliquely upward from the upper end of the rising guide part 54 in the wall surface direction, It is possible to guide to the position to receive the locking bracket. Further, when the rising guide portion 54 enters the through hole 43, the rising guide portion 54 is disposed so as to enter the center of the rotation locus from the rotation locus of the through hole 43. The peripheral wall surface 43 once hits the rising guide portion 54 and is elastically deformed so that the central portion in the longitudinal direction of the reflector 3 enters the central direction of the rotation locus. Then, the reflector 3 is further rotated to the reflection position, the reflector 3 is elastically restored to the original state, and the engaging portion 4 b is received at the receiving position of the receiving metal fitting 5.
Therefore, for example, when the head or the like hits the reflector 3 and the reflector 3 jumps up slightly, the reflector 3 does not jump up to the replacement position and returns to the original reflection position. That is, the longitudinal guide intermediate portion of the reflector 3 is bent inward by the rising guide portion 54, so that a part of the peripheral wall of the through hole 43 is pressed against the rising guide portion 54 by the elastic restoring force of the reflector 3. Thus, it is possible to prevent the locking metal fitting 4 from jumping upward over the rising guide portion 54. That is, the reflector 3 can be held in a stable state at the reflection position.

The present invention is not limited to the above embodiment. For example, in the above embodiment, there are two through holes in the locking metal fitting, but one may be used.
Further, in the above embodiment, the locking metal fitting is provided at one place in the center in the longitudinal direction of the reflector. However, the locking metal fitting and the receiving metal fitting corresponding to the locking metal fitting are provided at two positions with a predetermined interval. You may make it provide above.

Furthermore, in said embodiment, although used for the bathroom, you may attach to indoor walls other than a bathroom. Further, when the installation location is other than a humid location such as a bathroom, the waterproof structure of the lighting fixture body is not necessary.
In the above embodiment, the rising guide portion is parallel to the wall surface. However, it may not be parallel. Furthermore, the bending guide portion may be curved along the rotation trajectory of the through hole.
