Description of the Related Art Conventionally, a handrail that has a rod-shaped gripping part and an attachment part formed at a required portion of the gripping part and the gripping part is fixed to a wall surface via the attachment part is well known. Japanese Patent Laying-Open No. 2005-188030 (Patent Document 1) discloses a handrail in which a part of a gripping part is formed so as to emit light. In this known handrail, a single slit extending in the longitudinal direction is formed in the aluminum extruded tube. The outer side of the aluminum extruded tube is covered with a light-transmitting synthetic resin tube, and a wiring board in which a plurality of light emitting diodes are arranged in a row is inserted inside the aluminum extruded tube. The light from the light emitting diode exits from the slit, passes through the tube, and is emitted toward the outside of the handrail. The handrail can serve as a sign for guiding a pedestrian at night because the slit serves as a light emitting portion and can clearly indicate its position.
JP 2005-188030 A

  In the known handrail, a plurality of light sources such as light emitting diodes must be arranged close to each other in order to illuminate the entire light emitting portion with uniform brightness. Moreover, as the handrail becomes longer, not only a large number of light sources are required, but also the wiring board becomes complicated.

  An object of the present invention is to provide a handrail that can light a required portion of the handrail with uniform brightness without using a large number of light sources.

  In order to solve the above problems, the present invention is directed to a rod-shaped gripping portion having both end portions, an attachment portion for fixing the gripping portion to a wall surface, and at least the both end portions. A light source provided in the vicinity of one of them, and a surface of the gripping portion that is capable of irradiating the light traveling from the light source into the gripping portion toward the outside of the gripping portion and a non-irradiable non-irradiation A handrail including a transparent portion.

  In this handrail, the features of the present invention are as follows. The gripping part is formed of a pipe that includes the both ends and forms the non-transparent part, and a light-transmitting material filled in the pipe, and forms the transparent part. First and second filling members. The first filling member is formed from the inside of the pipe into a through hole formed on the peripheral surface of the pipe and communicating with the inside and outside of the pipe. The second filling member extends to the vicinity of the both end portions of the gripping portion, and at least one of both end surfaces located in the vicinity of the both end portions faces the light source. Inside the through hole, the first filling member and the second filling member are in surface contact with each other in the radial direction of the pipe, and are emitted from the light source to the second filling member. The entering light is irradiated toward the outside of the through hole through the first filling member.

  In one preferred embodiment of the present invention, the first and second filling members are in contact with the inner peripheral surface of the pipe.

  In another preferred embodiment of the present invention, at least one of the portions where the first filling member and the second filling member are in surface contact with each other in the radial direction of the pipe inside the through hole is light. It has a rough surface with a diffusion effect.

  In another preferred embodiment of the present invention, at least one of the portions where the first filling member and the second filling member are in surface contact with each other in the radial direction of the pipe inside the through hole, Sheet pieces that are light transmissive and have a light diffusing effect are joined.

  In another preferred embodiment of the present invention, the sheet piece is an adhesive tape piece.

  In another preferred embodiment of the present invention, the first filling member includes a first part that fits into the through hole from the inside of the pipe, and a second part that contacts the inner peripheral surface of the pipe. A third portion that is in surface contact with the second filling member, a fourth portion where the second filling member is in contact with the inner peripheral surface of the pipe, and a fifth portion that is in surface contact with the first filling member. And have.

  In still another preferred embodiment of the present invention, the second filling member has an end surface opposite to the one end surface facing a glossy surface provided in the vicinity of the end portion of the gripping portion.

  The handrail according to the present invention has a first filling member and a second filling member formed of a light-transmitting material inside a pipe that forms the grip portion and is non-transmissive to light. Since the first and second filling members are in surface contact with each other in the radial direction of the pipe, at least one of the end faces of the second filling member located near both ends of the gripping portion, When light from the light source facing this enters, a part of the light enters the first filling member and is irradiated from the through hole of the pipe toward the outside of the pipe. Since the light uniformly spread in the second filling member enters the first filling member, the entire first filling member, in other words, is formed in the pipe even if there is only one light source for the handrail. The entire inside of the through-hole shines with uniform brightness.

  In this aspect of the invention in which the first and second filling members are in contact with the inner peripheral surface of the pipe, the contact can suppress the movement of the first and second filling members inside the pipe. Moreover, the light which leaked from the 2nd filling member to the inside of a pipe can be returned to a 2nd filling member again by making the inner peripheral surface into a glossy surface.

  According to this aspect of the invention, in which at least one of the portions where the first filling member and the second filling member are in contact with each other is a rough surface having a light diffusion effect, the light of the second filling member is diffused on the rough surface. Since it enters into the 1st filling member after becoming light, it becomes easy to make the inside of a penetration hole shine with uniform brightness.

  Each part where the first filling member and the second filling member are in contact with each other is made rough by joining a light-transmitting sheet piece having a light diffusion effect to any of the parts. Can be replaced. An adhesive tape having a light diffusion effect can be used for the sheet piece.

  In this aspect of the invention in which the first filling member has first, second, and third portions, and the second filling member has fourth and fifth portions, the first portion has a length direction and a circumferential direction of the pipe. The third portion and the fifth portion, which are in surface contact with each other, stop the movement of the first and second filling members in the radial direction of the pipe and at the same time the second portion in the circumferential direction of the pipe. 2 The movement of the filling member can be stopped.

  In this aspect of the invention in which the opposite end surface of the one end surface of the second filling member faces the glossy surface, the light emitted from the opposite end surface is reflected by the glossy surface and enters the second filling member again. The brightness of the first filling member inside the through hole can be increased.

  The details of the handrail according to the present invention will be described with reference to the accompanying drawings.

  FIG. 1 is a perspective view of the handrail 1. The handrail 1 has a rod-like gripping portion 2 that forms a rod shape, in the figure, a column, and first and second brackets 3 a and 3 b that are attachment portions formed at both ends of the gripping portion 2. In the grip portion 2, through holes 4 that form an oval light emitting portion are formed in a row. The first and second brackets 3a and 3b have screw holes 6 used when the handrail 1 is fixed to a wall surface or the like. The 1st bracket 3a has the light emitting diode assembly 25 (refer FIG. 2) used as a light source inside, and the power cord 12 connected to the light emitting diode assembly 25 is extended out of the 1st bracket 3a.

  In the handrail 1, when a light emitting diode (not shown) in the light emitting diode assembly 25 is turned on, the light from the light emitting diode travels inside the gripping portion 2 in the length direction of the gripping portion 2, and The part is irradiated from the through hole 4 toward the outside of the grip part 2. Therefore, when the periphery of the handrail 1 is dark, the inside of the through hole 4 becomes a light emitting portion, and the presence of the handrail 1 becomes obvious, and the handrail 1 becomes a sign for a pedestrian or the like.

  2, 3 and 4 are cross-sectional views taken along lines II-II, III-III and IV-IV in FIG. In FIG. 2, the grip portion 2 includes a pipe 16 and first and second filling members 17 and 18 housed inside the pipe 16. The pipe 16 is made of metal or opaque plastic that is colored or painted so that light does not transmit, and a through hole 4 that connects the inside and outside of the pipe 16 is formed on the peripheral wall. ing. The first and second filling members 17 and 18 are made of a light transmissive material such as acrylic resin, polycarbonate resin, polyester resin, or inorganic glass. The first filling member 17 is fitted into the through hole 4 from the inside of the pipe 16, and is made slightly longer than the through hole 4 inside the pipe 16. The second filling member 18 has substantially the same length as the pipe 16, and extends to the vicinity of both ends of the pipe 16, that is, to the vicinity of both ends of the grip portion 2. In the radial direction of the pipe 16 shown in FIGS. 2 and 3, the first filling member 17 and the second filling member 18 are in surface contact with each other at the surfaces 17 a and 18 a inside the through hole 4. The 1st bracket 3a has the pipe insertion part 21 which can support the pipe 16 so that rotation is impossible, and the light source storage part 22 formed in the left side of the pipe insertion part 21 in the figure. A light emitting diode assembly 25 including a light emitting diode (not shown), a casing 23 therefor, a lens 24, a lead wire 26, and the like is attached to the light source housing 22 with screws 27. In the light emitting diode assembly 25, the lens 24 having a smooth outer surface (not shown) abuts on the smooth end surface 31 of the second filling member 18 from the left in the drawing, and the second filling member 18 moves to the left. It is preventing that. The internal structure of the second bracket 3b is the same as that of the first bracket 3a, but instead of the light-emitting diode assembly 25, a stopper assembly 28 made in substantially the same shape as this. Are attached by screws 29. The stopper assembly 28 comes into contact with the smooth end surface 32 of the second filling member 18 accommodated in the pipe 16 inserted in the second bracket 3b from the right side of the drawing, and the second filling member 18 moves to the right side. Blocking.

  FIG. 3 shows a cut surface of the cylindrical pipe 16 in the grip portion 2. A through-hole 4 is formed in the peripheral wall 34 of the pipe 16 so as to communicate with the inside and outside of the pipe 16. First and second filling members 17 and 18 are accommodated inside the pipe 16. The first filling member 17 abuts against the first portion 41 that fits into the through hole 4 from the inside of the pipe 16, the second portion 42 that contacts the inner peripheral surface of the pipe 16, and the flat surface 18 a of the second filling member 18. And a third portion 43 including a flat surface 17a in contact therewith. The second filling member 18 has a fourth portion 44 that contacts the inner peripheral surface of the pipe 16 and a fifth portion 45 that includes a flat surface 18 a that contacts the flat surface 17 a of the first filling member 17. The first filling member 17 does not move in the length direction and the circumferential direction of the pipe 16 because the first portion 41 abuts on the peripheral portion of the through hole 4. Further, the first filling member 17 and the second filling member 18 are not moved in the circumferential direction of the pipe 16 because the flat surface 17a and the flat surface 18a are in contact with each other. The flat surface 17a and the flat surface 18a may be a smooth glossy surface, or at least one surface may be a rough surface having light diffusibility.

  In the grip 2 shown in FIG. 4, only the second filling member 18 appears inside the pipe 16. The first filling member 17 is for fitting into the through hole 4 to make the inside of the through hole 4 a light emitting portion as will be described later, and is slightly smaller than the through hole 4 as shown in FIG. Since it is only necessary to be made long, it does not appear on the cut surface of FIG.

  In the handrail 1 formed in this way, when the power supply is turned on and the light emitting diode assembly 25 emits light, the light from the light enters the second filling member 18 from the end surface 31 toward the end surface 32, Meanwhile, part of the light exits the fifth portion 45 of the second filling member 18 and enters the first filling member 17 from the third portion 43 of the first filling member 17. The light is further emitted from the first portion of the first filling member 17 to the outside of the grip portion 2. However, the light that goes out from the circumferential surface of the second filling member 18 and travels toward the inner circumferential surface of the pipe 16 is not irradiated toward the outside of the grip portion 2. Therefore, in the handrail 1, the inside of the through-hole 4 in the grip portion 2 becomes a local light emitting portion in the handrail 1 to reveal the presence of the handrail 1, and the handrail 1 is used as a sign. Make it possible to do.

  When it is desired to increase the brightness inside the through-hole 4 that is the light emitting portion, the stopper assembly 28 used in the bracket 3b is replaced with the light emitting diode assembly 25 used in the bracket 3a, and the second filling member 18 is replaced. Light can also enter from the end face 32. Further, when it is desired to make the entire first portion 41 of the first filling member 17 uniform brightness, at least the planes 17a and 18a of the third and fifth portions 43 and 45 of the first and second filling members 17 and 18 are at least. One side is preferably a rough surface having a light diffusion effect. Such a rough surface can be obtained by treating at least one of the smooth flat surfaces 17a and 18a of the first and second filling members 17 and 18 made of, for example, acrylic resin with sandpaper.

  FIG. 5 shows an example of an embodiment of the present invention, and shows a partially enlarged view similar to FIG. On the flat surface 17a of the first filling member 17 in FIG. 5, for example, a sheet such as an adhesive tape having a light-transmitting but rough surface as known as a trade name mending tape (manufactured by Sumitomo 3M). A piece 48 is pasted. In such a first filling member 17, the light entering from the plane 17 a becomes diffused light, and the entire first portion 41 becomes a light emitting portion having substantially uniform luminance. Further, if the sheet piece 48 colored in an appropriate color is used, the first portion 41 can be easily made in that color.

  In the present invention, if the inner peripheral surface of the pipe 16 is made glossy, the light emitted from the outer peripheral surface of the second filling member 18 is reflected by the inner peripheral surface and enters the second filling member 18 again. It becomes easy to do, and the brightness | luminance of the 1st site | part 41 in the 1st filling member 17 can be improved. Further, the portion of the stopper assembly 28 that contacts the second filling member 18 is made a glossy surface to reflect the light emitted from the second filling member 18, and the light enters the second filling member 18 again. Also, the brightness of the first part 41 can be improved.

  In the handrail 1 according to the present invention, when the grip portion 2 is assembled, the first filling member 17 is first inserted into the pipe 16 and set in a predetermined portion, and then the second filling member 18 is attached to the pipe 16. insert. In this way, it is possible to easily obtain the grip portion 2 in which the inside of the through hole 4 of the pipe 16 is filled with the first filling member 17. Further, the first filling member 17 and the second filling member 18 may be made of different materials such as plastic and inorganic glass, or may be different in color.

  According to the present invention, it is possible to manufacture a handrail having a function as a sign.
