FIG. 1A is a partially cutaway perspective view showing a handrail according to an embodiment of the present invention, and FIG. 1B is a cross section taken along line BB in FIG. FIG. 2 is a longitudinal sectional view showing a support member connected to one of both ends of the main body in the handrail of FIG. FIG. 3 is a partially cutaway perspective view showing a handrail according to another embodiment of the present invention. FIG. 4 is a longitudinal sectional view showing an end support member connected to one of both ends of the main body of the handrail of FIG. 3 and an intermediate support member connected to an intermediate portion of the main body.

  Hereinafter, the present invention will be described in detail based on preferred embodiments with appropriate reference to the drawings.

  A handrail 1 shown in FIG. 1 includes a main body 2 and a pair of support members 3. The main body 2 is a member for the user to hold with the hand. The support member 3 is a member for fixing the main body 2 to an installation object 50 such as a wall surface. In the present embodiment, the main body 2 and the support member 3 are configured as separate members. However, the main body 2 and the support member 3 may be integrally formed.

  In the present embodiment, the main body 2 is formed in a cylindrical shape, but is not limited to such a structure. It may be a solid bar, a prism or a square tube. The main body 2 may be curved instead of being linear. The main body 2 may be made of a metal such as an aluminum alloy or stainless steel, may be made of a synthetic resin, may be made of wood or the like. The support member 3 is also called a bracket. In the present embodiment, the support member 3 is generally J-shaped. However, it is not limited to such a shape. For example, it may be L-shaped, T-shaped, or the like. In the handrail 21 shown in FIGS. 3 and 4 to be described later, the intermediate support member 23 attached to the intermediate portion of the main body 2 is substantially T-shaped. The main body 2 is connected to one end of the support member 3 and the other end is fixed to a wall surface 50 or the like. The main body 2 mounting side that is one end of the support member 3 is referred to as a distal end, and the wall 50 fixed side that is the other end is also referred to as a proximal end. In the present embodiment, the support member 3 is made of an aluminum alloy, but is not limited to such a material. It may be made of synthetic resin or stainless steel.

  As is apparent when referring also to FIG. 2, the body 2 has a groove 4 formed on the surface thereof along the longitudinal direction. A translucent body 5 is fitted in the groove 4. The translucent body 5 is a rod-shaped body formed from a translucent resin such as acrylic resin or polyester. This translucent body 5 is for radiating the light which passes through the inside to the outside. The translucent body 5 is not limited to a rod shape, and may be tubular. Further, in order to enhance the outward light emission effect, a stepped slope that becomes a prism may be formed on the back side (bottom side of the groove 4).

  The support member 3 can be connected to and disconnected from both ends of the main body 2. In the handrail 21 shown in FIGS. 3 and 4 to be described later, another intermediate support member 23 is attached to an intermediate portion of the main body 2 so as to be separable. A connection hole 6 having a circular cross section is formed at the tip of the support member 3. One end of the main body 2 is inserted and connected to the connection hole 6 together with the translucent body 5. The end surface of the main body 2 and the bottom 6a of the connection hole 6 are detachably connected by screws. A screw hole (not shown) is formed on the end surface of the main body 2. A through hole (not shown) is formed in the bottom 6 a of the connection hole 6. The position of the screw hole corresponds to the position of the through hole.

  With the above configuration, when the main body 2 is rotated with respect to the support member 3 by a multiple of the pitch of the screw holes (through holes) around the central axis, the position of the translucent body 5 in the handrail 1 is changed. The For example, when the main body 2 is rotated 180 ° around the central axis from the state shown in FIGS. 1 and 2 and connected to the support member 3, the translucent body 5 faces the wall surface 50 (FIGS. 3 and 4). reference). Then, the user sees the light reflected by the wall surface 50. In this case, the indirect illumination is easy on the eyes for the user. The shape of the handrail can also be clearly seen as a shadow. In addition, the number of the translucent bodies 5 is not limited to one, and a plurality of translucent bodies 5 may be arranged at different angular positions.

  The pair of support members 3 have the same shape and structure. The present invention may have different shapes and structures. The support member 3 includes a container part 7 and a lid 8 that opens and closes the opening of the container part 7. It is preferable that a seal member (not shown) is attached around the opening of the container part 7 or around the lid 8 corresponding to the opening. This sealing member seals the inside of the container part 7 in a liquid-tight manner from the outside. A through hole 9 for screwing to the installation object 50 is formed at the bottom of the container part 7. The light emitting device 10 is built in one support member 3 of the pair. The light emitting device 10 is a device for radiating light outward through the translucent body 5. The light emitting device 10 includes a battery 11, a control board 12, an LED (light emitting diode) 13, a human sensor 14, and an illuminance sensor 15. The battery 11, the LED 13, the human sensor 14, and the illuminance sensor 15 are electrically connected via the control board 12 by an electric cord 16.

  FIG. 2 shows a state where the battery 11 and the control board 12 are arranged in the container portion 7. However, the battery 11 and the control board 12 may be attached to the lid 8. The battery 11 is detachable. The LED 13 is disposed in the groove 4 at the end of the main body 2 inserted into the connection hole 6. The electric cord 16 connected to the LED 13 from the control board 12 passes through the through hole 17 in the bottom 6 a of the connection hole 6. It is preferable that a liquid-tight seal is formed between the through hole 17 and the outer periphery of the electric cord 16. The LED 13 is close to or in contact with the end of the light transmitting body 5 in the groove 4. When the LED 13 emits light, the light travels in the longitudinal direction while reflecting and transmitting the inside of the transparent body 3 with respect to the outer peripheral surface. The handrail 1 and the vicinity thereof are illuminated by light transmitted through the outer peripheral surface.

  The human sensor 14 and the illuminance sensor 15 are attached to the lid 8. The human sensor 14 is attached to the distal end side of the lid 8, and the illuminance sensor 15 is attached to the proximal end side of the lid 8. The human sensor 14 and the illuminance sensor 15 both have their detection portions 14a and 15a exposed outward from the through holes formed in the lid 8. It is preferable that a liquid-tight seal is formed between the through hole and the outer periphery of the detection units 14a and 15a. The battery 11 may be various dry batteries or rechargeable batteries. Or it may replace with a battery and may provide the electric wire connected to AC power supply and a converter. However, the use of a battery is preferable because the light emitting device 10 exhibits a light emitting effect even during a power failure caused by a lightning strike or the like.

  The human sensor 14 generates a detection signal when a moving object is detected by an infrared sensor or the like. In the present embodiment, the LED lighting command signal transmitted from the control board 12 causes the LED 13 to emit light based on the detection signal from the human sensor 14. The control board 12 is provided with a timer function. With this timer function, the LED 13 stops light emission after a predetermined time has elapsed from the time of light emission.

  The illuminance sensor 15 cooperates with the human sensor 14. The illuminance sensor 15 detects the illuminance of the surrounding environment. A threshold value is set for the illuminance sensor 15, and a predetermined operation of the illuminance sensor 15 occurs when the detected illuminance is above or below this threshold value. In the present embodiment, the function of the human sensor 14 is stopped and exhibited based on the detected illuminance of the illuminance sensor 15. When the illuminance sensor 15 detects illuminance less than the threshold value (when dark), no stop signal is sent to the human sensor 14. The human sensor 14 is in a normal operable state. Therefore, when the human sensor 14 detects a person's movement, the LED 13 emits light and is illuminated. When the illuminance sensor 15 detects an illuminance that is equal to or greater than the threshold (when it is bright), a stop signal is sent to the human sensor 14. As a result, the human sensor 14 becomes inoperable.

  As described above, by the cooperation of the human sensor 14 and the illuminance sensor 15, the handrail 1 and its vicinity are illuminated only in an environment where illumination is required. With this handrail 1, safety and convenience for the user can be obtained, and electricity can be saved.

  3 and 4 show another handrail 21. FIG. In the handrail 21, the main body 2 is divided into two in the longitudinal direction. The handrail 21 has an intermediate support member 23 that connects the two main bodies 2 to each other. The configuration other than the above is the same as the configuration of the handrail 1 shown in FIGS. 1 and 2. For example, the light emitting device 10 is built in one support member 3 of a pair attached to both ends of the handrail 21. Hereinafter, the support members 3 at both ends of the handrail 21 are also referred to as end support members 3. The same components as those of the handrail 1 in FIGS. 1 and 2 are denoted by the same reference numerals, and the description thereof is omitted.

  In this invention, it is not limited to the structure by which the main body 2 was divided into two. The main body 2 may be divided into three or more parts. When the main body 2 is divided into n, two end support members 3 and n-1 intermediate support members 23 are attached to the handrail. The main body 2 is attached to the support members 3 and 23 in a state where the main body 2 is rotated by 180 ° around its own axis from the state of the main body 2 shown in FIGS. That is, the transparent body 5 is made to face the surface of the installation target object 50 such as a wall to which the handrail 21 is attached.

  As shown in FIGS. 3 and 4, the intermediate support member 23 is formed on the leg portion 24, the container portion 27 formed on the upper portion (tip) of the leg portion 24, and the left and right ends of the container portion 27. It has a connection hole 26, a mounting plate part 25 formed at the lower part (base end) of the leg part 24, and a lid 28 for opening and closing the opening of the container part 27. In FIG. 4, the lid 28 is not shown. As in the connection hole 6 shown in FIG. 2, one end of the main body 2 is inserted into the connection hole 26 together with the translucent body 5. Then, the main body 2 is connected to the intermediate support member 23 by a set screw or the like. Various cross-sectional shapes can be adopted for the connection hole 26 according to the cross-sectional shape of the main body 2. A through hole 37 is formed in the bottom portion 26 a of the connection hole 26.

  The attachment plate portion 25 is a portion attached to the surface of the installation target object 50 such as a wall. A through hole 29 for screwing the installation target object 50 is formed in the mounting plate portion 25. In the present embodiment, there is no member accommodated inside the container portion 27. However, as will be described later, an electric cord 16 for supplying power to the LED 13 passes through the container portion 27.

  LED13 for illumination is arrange | positioned at the both ends of the said main body 2. As shown in FIG. The LED 13 is disposed in the groove 4 at both ends of the main body 2 inserted into the connection holes 6 and 26. The arrangement of the LEDs 13 is not limited to both ends of the main body 2 and may be only one end. However, when the length of the main body 2 is long, it is preferable that the LEDs 13 are arranged at both ends from the viewpoint that the illumination light from the translucent body 5 becomes uniform and strong. The same applies to the handrail 1 shown in FIGS. 1 and 2. The electric cord 16 connected to the LED 13 from the control board 12 includes a cavity 2a in one main body 2, through holes 17 and 37 in the bottom portions 6a and 26a of the connection holes 6 and 26, and a cavity 2a in the other main body 2. Extending through.

  The light emitting device 10 is built in one end support member 3. However, it is not limited to such a configuration. For example, the light emitting device 10 may be incorporated in at least one of the intermediate support members 23. In this case, it is preferable that a space (not shown) for accommodating the components of the light emitting device 10 is also provided in the leg portion 24 as necessary. This space may be communicated with the inside of the container portion 27.

  The human sensor 14 and the illuminance sensor 15 may change their attachment positions as necessary. That is, at least one of the human sensor 14 and the illuminance sensor 15 may be attached to the intermediate support member 23 or may be attached to the end support member 3. The illuminance sensor 15 may be attached to the intermediate support member 23 at a position facing the surface of the installation target object 50.

  These handrails 1 and 21 may be attached with the longitudinal direction thereof directed upward and downward. At this time, the end support member 3 containing the light emitting device 10 may be positioned above or may be positioned below. When the end support member 3 is positioned upward, the detection unit 15a of the illuminance sensor 15 faces upward. When the end support member 3 is positioned below, the detection unit 15a of the illuminance sensor 15 faces downward. In any case, the detection unit 14a of the human sensor 14 faces forward (the direction opposite to the wall surface 50). In this way, the human sensor 14 faces in the best direction for performing its function. When the handrails 1 and 21 are attached to a wall surface such as a corridor in a horizontal direction in a posture, the human sensor 14 may be attached at the position shown in FIGS. The same applies to the case where the handrails 1 and 21 are attached at an inclination on the stairs.

  In the handrail 1 of FIG. 1, the light emitting device 10 is built in only one of the pair of end support members 3 as described above. This single light emitting device 10 emits light over the entire length of the translucent body 5. Therefore, when the handrail 1 is installed, there is no problem even if the main body 2 is cut together with the translucent body 5 in order to adjust its length.

  In the handrail 21 of FIG. 2, a continuous long handrail can be formed. For example, it is possible to cope with a long corridor, a long staircase, and the like with a single handrail provided with one or more intermediate support members 23. In the long handrail 21, for example, the light emitting device 10 can be provided on each of the intermediate support members 23 that are appropriately spaced. In this case, the electric cord 16 is divided at the intermediate support member 23 provided with the light emitting device 10. According to the handrail 21, the human sensor 14 and / or the illuminance sensor 15 can be independently operated in different ranges divided by the intermediate support member 23 including the light emitting device 10.

  In the embodiment described above, light is emitted outward only from the translucent body 5. However, it is not limited to such a configuration. For example, the main body 2 itself may be formed from a light-transmitting material such as an acrylic resin. In such a handrail, since light is emitted from the entire main body 2, visual recognition can be further facilitated.

  The handrail according to the present invention is not limited to indoor staircases, corridors, washrooms, toilets, and the like, but can be similarly applied to places where an outdoor handrail is required.
