BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting device provided on a handrail. More specifically, the present invention relates to a wiring structure of a handrail lighting device that is attached to a handrail standing upright on the stairs and illuminates the foot of the user.

[0002]

2. Description of the Related Art In a house having a garage on the first floor or a two-family house, the entrance is often installed higher than the gate. In a house having such a structure, the entrance from the gate to the entrance is A staircase is installed on the outside. Beside the stairs, in order to assist walking and prevent the risk of falling, etc., especially in a house where elderly people live,
Handrails are often provided.

The above-mentioned stairs installed on the outside of the house have been improved in convenience and safety by installing handrails, but at night, various lighting fixtures such as gate lights, nameplate lights, etc. However, since it cannot be said that the feet are sufficiently confirmed on the stairs, the lighting device is attached to the back surface of the handgrip of the handrail, a pillar, or the like.

FIG. 9 is a perspective view of a conventionally known handrail which is erected on a staircase and has an illuminating device attached to a column. In FIG. 9, the handrail 1 is composed of a handgrip portion 2 and a column 3, and an illumination device 4 is attached to the column 3.
The power line 5 is connected to a power source such as a solar cell and a household AC power source, and is wired to each lighting device 4 shown in FIG. 9 so that the user can walk on the stairs safely and comfortably at night or at other times. Lighting. However, as can be seen from FIG. 9, the power supply line 5 to each lighting device 4 is not visible from the outside because it is drawn into the support column 3, but the power supply line 5 between the support column 3 and the support column 3 is not visible. 5 is exposed to crawl on the back surface or the lower part of the grip portion 2, and further, the power supply line fixing means 6
However, it is necessary to fix it in places, which is not preferable in appearance.

FIG. 6 is an exploded enlarged perspective view showing a state in which the clamp C is used as the power supply line fixing means 6 and the power supply line 5 is fixed to the side surface of the projecting portion 21 extending downward in the longitudinal direction of the grip portion 2. It is a figure. As can be seen from FIG. 6, the protrusion 2
V-cut groove portions 211 are provided along the longitudinal direction of the protruding portion 21 on both outer side surfaces of the clamp C.
Is fixed to the side surface of the protrusion 21 by screwing the tapping screw B into the groove 211. The groove portion 211 is provided so that the blade edge of the drill does not slip when the clamp C is screwed with the tapping screw B.

In FIGS. 7 and 8, a clamp D adhered to the outside of the side surface of the protrusion 21 with a double-sided adhesive tape (not shown) is used as the power supply line fixing means 6, and the power supply line 5 is protruded. FIG. 3 is a front view and a side sectional view showing a state of being fixed to a side surface of the. Reference numeral 8 is a joint portion shown in FIG.
As shown in FIGS. 7 and 8, the grip portion 2 is screwed to the groove portion 211 by the joint portion screw 81 to support and fix the grip portion 2 to the support column 3. Although not shown, also in the case of using the clamp C, similarly to the above, the grip portion 2 is screwed to the groove portion 211 by the joint portion screw 81 via the joint portion 8 and is supported and fixed to the column 3. Since it is configured as described above, if the screw 81 is loosened, the grip portion 2 becomes the screw 8
It can be rotated around 1 as a fulcrum, the inclination of the grip 2 is adjusted according to the slope of the stairs, and the screw 81 is tightened again, so that the construction can be easily performed according to the stairs on the site. .

Provided is a wiring structure for a handrail lighting device, in which a power supply line passes through a wiring space of a power supply line cover part having a substantially U-shaped side cross section that elastically engages, and the power supply line is wired as a lead-in wire inside the pillar. . With the above-described configuration, the power supply line is drawn into the inside of the column through the wiring space of the power supply line cover portion, and is wired to each lighting device. Therefore, the power supply line cannot be seen from the outside, and a wiring structure excellent in design can be provided.

Further, it is preferable that the groove portion extending in the outer longitudinal direction on both side surfaces of the projecting portion and the engaging projection portion constituting the upper portion of the power supply line cover portion are elastically engaged. In the known art, the groove is a power supply wire fixing means used for fixing the power supply wire to the side surface of the protrusion, for example, one provided so that the cutting edge of the drill does not slip when screwing the clamp. However, this groove can be used. In this way, the above-mentioned engagement protrusion is firmly engaged with the existing groove for screwing, and the power supply line cover is prevented from falling off from the protrusion.

It is preferable that a stopper of a ridge is provided in the longitudinal direction at substantially central portions on the inner sides of both sides of the power supply line cover portion. By providing the stopper, the stopper and the bottom of the protrusion contact each other, and at the same time, the groove and the engagement protrusion elastically engage with each other, so that the power supply line cover is firmly held by the protrusion.

Further, it is preferable that the grip portion is rotatably supported by the column via the joint portion. By doing so, the degree of inclination of the grip portion can be adjusted according to the gradient of the stairs, so that it is possible to perform construction at the site with good workability. The power source of the power source line is a solar cell or a household AC power source.
