Power is supplied to 31.

  Referring to FIGS. 2, 4, and 5 (a) to 5 (c), the fastener portion 50 is a cylindrical grommet 70 fitted into the pin 60 and the front end opening 20 a located at the distal end 23 a of the insertion portion 23. And have. The grommet 70 is a molded product of an elastically deformable thermoplastic synthetic resin such as ABS resin, polyacetal resin, or polycarbonate resin, and has a flange-like seat portion 71 having a substantially circular opening, and extends forward from the seat portion 71. Including the hanging part. A pin insertion hole that penetrates the seat portion 71 and the hanging portion is formed in the central portion of the grommet 70. The seat portion 71 has an annular step portion formed on the inner peripheral surface thereof, that is, on the periphery of the insertion hole. A cam surface 74 that undulates in the circumferential direction of the seat portion 71 is formed in the annular step portion.

  The hanging portion has a substantially cylindrical shape divided into four parts, and has four leg portions 75 adjacent to each other at regular intervals in the circumferential direction, and between the leg portions 75 adjacent to each other in the circumferential direction. A gap extending from the upper end to the lower end is formed. Moreover, four protrusions (not shown) are formed on the seat 71 side of the upper end of each leg 75. The leg portion 75 includes a base portion 76 that extends downward from the lower end of the seat portion 71 and an action portion 77 that bends and extends inward from the lower end of the base portion 76. The action part 77 has an inclined part 77a extending obliquely inward from the lower end of the base part 76 on the inner surface side of the leg part, and an inner end part extending linearly downward from the inclined part.

  Unlike the grommet 70, the pin 60 does not need to be elastically deformed. Therefore, the pin 60 can be formed of a hard material, for example, a thermoplastic synthetic resin such as ABS resin, polyacetal resin, polycarbonate resin, or metal, and has a minus in the center. It has a substantially circular head 61 having a concave groove 61a into which the tip of an operation tool such as a driver is inserted so as to be fitted, and a shaft 63 extending downward from the head 61. The shaft part 63 has an extending part that is gradually reduced in diameter toward the tip, and the extending part is formed with four rib-shaped guide parts 64 and a groove part positioned between the guide parts 64. Yes. A stopper 65 having substantially the same diameter as the shaft 63 is formed at the lower end (front end) of the extending portion. The stopper portion 65 has a curved shape whose lower end is slightly convex downward (forward), and its outer dimension is larger than the outer dimension of the lower end portion of the hanging part of the grommet 70. It acts as a retaining of the pin 60 with respect to 70. At the lower end of the head 61 of the pin 60, there is a pair of engaging projections 62 that extend downward in a tapered shape. The engaging convex part 62 has a sliding surface that undulates in the circumferential direction following the shape of the cam surface 74 formed on the inner surface of the seat part 71 of the grommet 70.

  In the state in which the pin 60 is inserted into the grommet 70 (the state before fitting), the shaft portion 63 is inserted into the insertion hole of the grommet 70, and the guide portion 64 of the pin 60 is inserted into the gap of the grommet 70. The rotation of the pin 60 in the grommet 70 is prevented. In such a state, the engaging projection 62 of the head 61 and the cam surface 74 of the seat 71 face each other in a fitted state, and the head 61 is seated by pushing the pin 60 downward as it is. It can be fitted to the annular step portion of the portion 71.

  When a force to rotate the head 61 is applied from the engaged state, the tip of the engaging convex portion 62 that has been in contact with the bottom of the cam surface 74 rises up with respect to the cam surface 74. And move upward while sliding. At the same time, the shaft portion 63 of the pin 60 also moves upward while rotating, and the tip portion is brought into sliding contact with the action portion 77 while rotating from the upper side toward the lower side. At the same time, the drooping portion is released from the expanded state and returns elastically. When the pin 60 is rotated by about 45 ° in one direction or the other direction, the engaging convex portion 62 is detached from the cam surface 74 and the tip portion comes into contact with the top portion 74a of the cam surface 74, and the same direction. Further, the guide portion adjacent to the rotation direction side, which is different from the guide portion located below the arbitrary gap in the fastening state, is inserted into the gap.

  The process of attaching the cap 10 having such a configuration to the handrail pipe 1 will be described. First, the fastener portion 50 is inserted into the cap main body 20 from the rear end opening 20b, and the grommet 70 is attached to the rear surface of the opening edge of the front end opening 20a. The fastener 50 is attached to the cap body 20 by pushing in until the front end comes into contact. Next, the insertion part 23 of the cap main body 20 assembled with the fastener part 50 is inserted into the inside from the one opening end 2a of the handrail pipe 1 and pushed in until the flange part 24 comes into contact with the one opening end 2a. As shown in FIG. 5A, the fastener portion 50 is not engaged with the pin 60 and the grommet 70 and the head portion 61 is separated from the seat portion 71 when attached to the cap body 20. Yes. Next, a slotted screwdriver is inserted from the rear end opening 20 b of the cap body 20, and the tip end of the cap body 20 is inserted into the concave groove 61 a located in the head portion 61 of the pin 60 and pushed forward, whereby the leg portion 75 of the grommet 70. And the action part 77 comes into contact with the inner peripheral surface of the handrail 1, and the cap body 20 is stably fixed therein.

  Further, the coil spring 28 and the power supply unit 40 are sequentially inserted from the rear end opening 20 b of the cap body 20, and finally the light emitting unit 30 is attached to the one end 2 of the handrail pipe 1. Since the power supply unit 40 is urged rearward by the coil spring 28 in the cap body 20, the power supply unit 40 is attached so as to be pushed in with the light emitting unit 30 and the rear end 42 of the power supply unit 40 in contact with each other. By doing so, the first terminal 36 of the light emitting unit 30 and the second terminal 43 of the power supply unit 40 are always in contact with each other, and the state where the power supply unit 40 and the control unit 31 are electrically connected is maintained. The

  Thus, since the cap 10 is detachably attached to the handrail 1, even if the internal mechanism or the like of the control unit 31 of the cap 10 breaks down, it is only necessary to replace the light emitting unit 30. Easy to replace. Further, since the handrail 1 need not be repaired or replaced, for example, the cost can be reduced as compared with the case where the electronic device arranged in the handrail 1 is repaired or replaced. Moreover, when attaching the cap 10 to the handrail 1, the cap body 20, the fastener portion 50, the coil spring 28, and the power supply unit 40 may be inserted into the cap body 20 in this order. If these components are removed from the cap body 20 in order, and the fastening of the fastener portion 50 is released by inserting the tip of a flathead screwdriver into the concave groove 61a of the head 61 of the pin 60 and rotating it. Since it is good, the attaching / detaching operation is relatively simple.

  Moreover, in the normal fastener part 50, although it couple | bonds by moving the pin 60 with respect to the grommet 70 to a linear direction, like the cap 10 of this embodiment, it is on the handrail 1 with a comparatively small diametrical dimension. It is difficult for the operator to grip and pull the pin 60 located in the inserted insertion portion 23. In the fastener portion 50 according to the present embodiment, since the coupling with the grommet 70 is released by rotating the pin 60, the cap 10 can be easily attached to the handrail 1 by inserting an elongated rod-like tool such as a flat-blade screwdriver. Can be removed from. However, when the handrail 1 has a diameter that allows the pin 60 to be pulled when the cap 10 is removed, a known fastener that is normally used as a fastening means can be used.

<Modification>
FIG. 6 is a cross-sectional view similar to the view of the cap 10 in an example of a modification. In the present modification, the light emitting unit 30 has a shape that extends rearward from the collar portion 24 of the cap body 20 and bends and extends downward, and is an LED light emitting body 35 positioned at the rear end 10 b of the cap 10. Is located opposite the ground. Thus, when the light emitting part 30 is bent, the bent part can function as a gripping part for a pedestrian or the like to grip. In addition to this modification, the light emitting section 30 may be bent upward, or may be formed in a cross-sectional wave shape so as to undulate vertically. The light emitting unit 30 is rotatably screwed to the cap body 20.
