  Utility Model Registration No. 3174769   Japanese Patent No. 3660292

  The handrail shown in Patent Document 1 is provided with a groove-shaped attachment portion that is recessed from the surface of the cross member, and a strip-like illumination portion that includes a plurality of LEDs is attached thereto. Since this handrail has a lighting function, it has the effect of illuminating the feet when attached to the stairs. However, the balustrade of this handrail is made of wood and is suitable mainly for use in buildings. Wood is not preferable from the viewpoint of durability as a material for handrails installed on stairs in the outdoors. In addition, some contrivance is required to provide the illumination means on the specially shaped handrail shown in Patent Document 2.

  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a handrail device that can be installed particularly for outdoor staircases and can easily attach an illumination device to a special handrail shown in Patent Document 2.

  The handrail device of the present invention includes an opaque main body tube having a slit in the longitudinal direction, and a long illuminating body made of a flexible resin having a large number of LEDs incorporated therein, and at least below the illuminating body A pair of grooves into which the opposite end faces of the slit of the main body tube are fitted, and the illuminating body is inserted from the slit of the main body tube, and the slit of the slit is inserted into the pair of grooves. The opposing end face is inserted and the said main body tube and the illumination body are couple | bonded.

Further, the main body tube is bent into a waveform.
Further, the LED is molded with a translucent first resin that is opaque or nearly opaque except for a portion where light is emitted, and the molded body is molded with a second resin that is transparent or nearly transparent.

Further, a power supply line for supplying power to the LED is molded with the first resin.
In addition, polyvinyl chloride is used as the resin.
In addition, a light guide portion that guides light emitted from the LED downward is formed of the first resin, and the light guide portion is filled with the second resin.

  As described above, the handrail device of the present invention can be installed outdoors or can be installed indoors and can be used widely. The illuminating body is integrated with the main body tube, which can illuminate the pedestrian's feet, which is particularly effective in dark outdoors and indoors. Furthermore, since the illuminating body is flexible, it is only necessary to insert both end faces of the slits into grooves provided in the illuminating body through the slits of the main body tube, and the coupling between the two is extremely easy. Even when the main tube is corrugated, it can be easily attached.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a side view of a handrail device in an embodiment of the present invention. This handrail device includes a main body tube 1, an illuminating body 2, and covers 3a and 3b provided at both ends. The main body tube 1 is corrugated, and has a straight portion 5 between a curved portion 4a curved upward and a curved portion 4b curved downward.

  The body tube 1 is manufactured by processing a metal such as stainless steel or aluminum. Specifically, as shown in FIG. 6, a slit 6 for attaching the illuminating body 2 is provided in the longitudinal direction of the main body tube 1. A straight metal tube is processed into a corrugated shape, and then the slit 6 is processed. It is also possible to manufacture the main body tube 1 by resin processing. An aluminum core covered with a resin tube can also be used.

  The illuminating body 2 has a shape shown in FIG. LED7 is used as an illumination lamp, and terminals 8a and 8b are connected to power supply lines 9a and 9b by lead wires 10a and 10b. These LED 7, power supply lines 9 a and 9 b, and lead wires 10 a and 10 b are molded with the first resin 11. The tip portion 12 of the LED 7 is not molded with the resin 11. The first resin 11 has an H-shaped cross section, and the tip of the LED (the portion from which light is emitted) is configured to exist at the innermost portion of the recess (light guide portion) 13 of the first resin 11.

  The first resin 11 is preferably made of opaque polyvinyl chloride (PVC). PVC is difficult to burn, and by adding an additive, it can have a wide range of properties from soft to hard, transparent to opaque, and the normal heat resistant temperature is 60 to 80 ° C. The first resin 11 is flexible and is opaque or translucent. Thereby, the light of LED7 comes out from the recessed part 13 outside.

  The entire first resin 11 is further molded with the second resin 14. The concave portion 13 is also filled with the second resin 14. On both lower sides of the second resin 14, grooves 16a and 16b into which the end faces 15a and 15b of the slit 6 shown in FIG. The lowest end portion of the second resin is a curved portion 17 so as to cover the slit 6 of the main body tube 1. As the second resin 14, polyvinyl chloride having flexibility similar to the first resin 11 is used, but a transparent or nearly translucent material is used. When the first resin 11 and the second resin 14 are both translucent materials, the second resin 14 is naturally more transparent than the first resin 11.

  Next, how to make this illumination body 2 will be described. A large number of LEDs 7 are provided on the long sheet 17. These LEDs 7 are divided into a plurality of series connection bodies 18 in which a plurality of LEDs are connected in series. These series connection bodies 18 are connected in parallel to the power supply lines 9a and 9b. The power supply lines 9a and 9b are connected to the DC power supply 20 via the switch 21 and the resistor 19 later. About 80 LEDs 7 are provided per meter. The power consumption of the LED 7 is 0.06 watt per LED.

  The sheet 17 provided with the LED 7 and the power supply lines 9a and 9b are placed in the molds 22a and 22b as shown in FIG. 4, and opaque polyvinyl chloride is injected from the resin insertion port 23 and hardened. Both ends of the power supply lines 9a and 9b are drawn out from the molds 22a and 22b. Next, what is configured in this manner is placed in the molds 24a, 24b, 24c, and 24d shown in FIG. 5, and transparent or translucent polyvinyl chloride is injected from the resin injection ports 25, 25a, and 25b to be hardened. Make it. When the molds 24a, 24b, 24c, and 24d are removed, the illuminating body 2 shown in FIG. 2 is obtained.

  As shown in FIG. 7, the illuminating body 2 joins the main body tube 1 and the illuminating body 2 by inserting the end faces 15 a and 15 b of the slit 6 of the main body tube 1 into the grooves 16 a and 16 b of the illuminating body 2. When the switch 21 is turned on, all of the LEDs 7 are turned on, and the light exits from the lower end of the illuminator 2 through the recess 13 of the first resin 11.

Although the main body tube 1 is corrugated as shown in FIG. 1, the illuminating body 2 has flexibility, so that the illuminating body 2 is inserted from the slit 6 of the main body tube 1, and the grooves 16a, 16b and the main body Tube 1 can be joined.
Of course, the main body tube 1 can be implemented with a linear shape instead of a special one with a waveform.

As shown in FIG. 8, the handrail device is used by being attached to a wall surface along a staircase 26 with a mounting bracket 27. Since the main body tube 1 has the curved portions 4a and 4b and the straight portion 5, as can be seen from FIG. 8, a horizontal portion 28 and a vertical portion 29 are formed, and a person climbing the stairs 26 uses the horizontal portion 28 in place of a cane. You can easily go up the stairs by grasping the part 29 and pulling it.
This handrail device can be installed outdoors or can be installed indoors. And since the illumination body 2 is united, it can illuminate a pedestrian's step and is effective especially in the dark outdoors. Furthermore, since the illuminating body 2 is flexible, it can be easily attached by being inserted through the slit 6 of the main body tube 1. Even when the body tube 1 is corrugated, it can be easily attached.

  The handrail device of the present invention is particularly effective when used as a handrail for outdoor stairs.
