Description

  The present invention relates to an illuminated handrail installed on a staircase or a hallway of a house or the like.

  Recently, handrails for walking guides or walking aids have been attached to wall surfaces such as corridors and stairs, not only during new construction and renovation, but also in existing houses.

  Among such handrails, those having lamps that illuminate corridors and stairs have been developed so that they can walk safely in the dark at night (for example, Patent Document 1).

  As shown in FIG. 4, the handrail 1 of Patent Document 1 is attached to a wall surface 4 via a handrail rod 2 and a bracket support plate 3, a bracket 5 that supports the handrail rod 2, and an inclination of the bracket 5. It is comprised with the light-emitting body 6 attached to the side surface 5a.

  In this handrail 1, the inclined side surface 5 a of the bracket 5 to which the light emitter 6 is attached is directed obliquely downward toward the center of the corridor or stairs where the handrail 1 is provided. Since it is possible to illuminate the center of the stairs, the safety of walking at night can be improved.

JP 2003-161018 A JP-A-8-120875

  However, the handrail 1 of Patent Document 1 has a problem. That is, as described above, the light emitter 6 is attached to the handrail 1, and the power supply wiring 7 for supplying power to the light emitter 6 is provided on the attachment surface 5 b of the bracket 5 with respect to the bracket support plate 3. A coupler (not shown) connected to a power supply wiring 7 extending from another bracket 5 is also accommodated in a wiring accommodating groove 3a provided on the surface of the bracket support plate 3 through the insertion hole 5c. It is accommodated in the accommodation groove 3a.

  As described above, in the handrail 1, the power supply wiring 7 is accommodated in the wiring accommodating groove 3a of the bracket support plate 3 so as to be bent substantially at right angles immediately after exiting the wiring insertion hole 5c provided with the mounting surface 5b of the bracket 5. Therefore, after the bracket 5 is attached to the bracket support plate 3, it is almost impossible to insert the power supply wiring 7 from the outside through the wiring receiving groove 3a and the wiring insertion hole 5c, and in addition, it is bent at a right angle. The power supply wiring 7 accommodated in this manner is in a state where it is fixed at the bent portion 8 and cannot be smoothly slid.

  For this reason, before attaching the bracket 5 to the bracket support plate 3, the power supply wiring 7 must be inserted into the bracket 5 by a necessary length in advance, and the bracket 5 must be attached while taking care of the power supply wiring 7. Because it was not possible, it took a lot of work on site.

  In addition, after the bracket 5 is attached to the bracket support plate 3, it is not possible to push the excess power supply wiring 7 into the bracket 5, and it is necessary to clean up the excess power supply wiring 7 in the wiring receiving groove 3 a. Therefore, not only the work on site is further time-consuming, but also there is a possibility that the aesthetic appearance of the finished state may be impaired, for example, the power supply wiring 7 may protrude and be exposed.

  Further, in the stair railing device disclosed in Patent Document 2, a concave groove is provided on the lower surface of the handrail bar, and after fitting a connecting metal fitting extended from the bracket into the concave groove, the power supply wiring is accommodated. However, it is not easy to accommodate the power supply wiring in the concave groove in which the connecting metal fitting is fitted, and as with the technique of Patent Document 1, it takes a lot of work on site.

  The present invention has been developed in view of such problems of the prior art. Therefore, the main problem of the present invention is that the power supply wiring for supplying power to the light emitter can be easily and reliably accommodated in the bracket at the time of construction, and the finished appearance is ensured without taking the trouble of construction. The object is to provide a handrail with illumination.

The invention described in claim 1
“Handrail bar 12 gripped by the user,
A bracket body 22 which has a handrail attachment portion 32 to which the handrail rod 12 is attached, and which is attached to a wall surface A in which an accommodation recess 26 for accommodating the power supply wiring 18 and the light emitter 16 is formed ;
A cover 24 covering the receiving recess 26 of the bracket body 22;
A light emitter 16 housed in the bracket body 22 ;
A power supply wiring 18 for supplying power to the light emitter 16,
The handrail bar 12 is formed with a wiring groove 20 into which the power supply wiring 18 is fitted.
The handrail mounting portion 32 of the bracket body 22 is provided with a positioning guide 70 that is fitted into the wiring groove 20, and a power supply for inserting the power supply wiring 18 into the bracket body 22 from the outside. The lighted handrail 10 ”is characterized in that the wiring insertion holes 56 are formed adjacent to both sides of the positioning guide 70 from the side walls .

In the illuminated handrail 10 to which the present invention is applied, a positioning guide 70 that is fitted into the wiring groove 20 of the handrail rod 12 is protruded in the handrail mounting portion 32 of the bracket body 22 , and the positioning guide 70 is also provided. A feed wire insertion hole 56 for inserting the feed wire 18 into the bracket body 22 from the outside is formed at positions adjacent to both sides of the wire.

Thus, as shown in FIG. 3, the handrail bar 12 is attached to the handrail mounting portion 32 of the bracket body 22 so that the positioning guide 70 is fitted into the wiring groove 20 of the handrail bar 12 (FIG. 3A), After that, when the leading end of the power supply wiring 18 is fed into the bracket body 22 from the inside of the wiring groove 20 through the power supply wiring insertion hole 56, at least a handrail attachment portion is provided between the power supply wiring insertion hole 56 and the bottom of the wiring groove 20. Since the distance corresponding to the height of the positioning guide 70 projecting from 32 is secured, the power supply wiring 18 can be obtained by pressing the tip of the power supply wiring 18 slightly downward against the side end of the positioning guide 70. Can be easily slid into a power supply wiring insertion hole 56 formed adjacent to the positioning guide 70 (FIG. 3B). In addition, after the tip enters the power supply wiring insertion hole 56, the power supply wiring 18 can be easily handed into the bracket body 22 (FIG. 3C).

According to the illumination with the handrail 10 of the present invention, the work for attaching the handrail rod 12 to the bracket body 22, since the feed interconnections 18 can be divided and a working interleaving in bracket body 22, construction site is easy in Become.

In addition, even after the bracket main body 22 is attached, the excess power supply wiring 18 can be pushed into the bracket main body 22 , so that the power supply wiring 18 can be easily protruded without being exposed. The finished state can be achieved.

The invention described in claim 2 relates to the illuminated handrail 10 of claim 1,
“The bracket body 22 is formed so that its bottom surface 36 is directly below or directly from the bottom toward the wall surface A,
The light-emitting body 16 is characterized in that the light-emitting portion 17 is disposed at a position recessed from the light exit opening 44 provided in the bottom surface 36. "

  The handrail 1 of Patent Document 1 described above has another problem. That is, the inclined side surface 5a of the bracket 5 in the handrail 1 is directed obliquely downward toward the center of the passage or the staircase. When the handrail 1 is viewed from the front, the light emitter 6 disposed on the inclined side surface 5a of the bracket 5 is Since direct viewing is possible, there is a possibility that direct light from the light emitter 6 may enter the eyes of the user (especially a short child), causing unpleasant glare, In view of the appearance of the handrail 1, the light emitter 6 is more noticeable than necessary, and there is a problem that it is difficult to improve the design of the handrail rod 2 and the bracket 5.

  Further, when the long handrail bar 2 is supported using a plurality of brackets 5, it is not necessary to attach the light emitters 6 to all the brackets 5. For example, every other group of brackets 5 arranged at predetermined intervals. In the embodiment in which the light emitter 6 is attached, the brackets 5 to which the light emitters 6 are attached and the brackets 5 that are not so are alternately arranged. At this time, as described above, since the presence or absence of the light emitter 6 can be seen at a glance from the front, there is a problem that it is difficult to obtain a sense of unity as the entire handrail 1. In particular, when a translucent milky white resin cover that diffuses and transmits the light from the light emitter 6 is provided on the inclined side surface 5a, the bracket 5 to which such a resin cover is attached and the bracket 5 without the resin cover have the appearance shape. Is clearly different, and the overall sense of unity is further impaired.

  With respect to such a problem, in the bracket 14 of the present invention, the bottom surface 36 provided with the light exit opening 44 is set to be directly below or from the bottom directly toward the wall surface A, so that the bottom surface 36 is illuminated. It cannot be seen from the front direction of the handrail 10. As long as the bottom surface 36 cannot be seen in this manner, the light exit opening 44 provided on the bottom surface 36 cannot be directly viewed, and the light emitter 16 is disposed in the bracket 14 at a position where the light emitting portion 17 is recessed from the light exit opening 44. Therefore, the user does not look directly at the light emitter 16 and does not feel uncomfortable glare. Further, since the light emitter 16 emits light immediately below or directly from the bottom toward the wall surface A, part of the light from the light emitter 16 also serves as indirect illumination to the wall surface A, creating a soft and refined atmosphere. it can.

  Therefore, according to the illuminated handrail 10 of the present invention, the user can not directly view the light emitting surface of the light emitter from the front, so that the user does not feel unpleasant glare and the design is improved. It is easy to improve, and furthermore, the front view appearance is common regardless of whether or not the light emitter is attached, and a sense of unity as a whole can be obtained.

The invention described in claim 3 relates to the illuminated handrail 10 according to claim 1 or 2,
And wherein "said feed line 18 drawn into the housing recess 26, a coupler 46 that connects the light-emitting body 16 electrically is, the housing recess 26 are housed in" it.

  According to the present invention, since the coupler 46 that electrically connects the power supply wiring 18 and the light emitter 16 is accommodated in the accommodation recess 26 of the bracket body 22, the connection work between the power supply wiring 18 and the light emitter 16 ( That is, it becomes possible to easily perform the connecting operation of the coupler 46 after the bracket 14 is fixed to the wall surface A, and the workability is remarkably improved. Further, even if some power supply wiring 18 is left, by placing them in the accommodation recess 26, it is possible to finish the wiring with a clean appearance.

  According to the present invention, since the power supply wiring can be easily and reliably accommodated in the bracket after the handrail rod is attached to the bracket at the time of construction, it ensures the aesthetics of the finished state without taking the trouble of construction. can do.
