  The handrail belt 3 has a substantially flat Ω-shaped cross section integrally including an upper belt-like portion 9 and a jaw portion 10 that is bent in an arc shape from both sides of the belt-like portion 9 and extends below the belt-like portion 9. One jaw portion 10 and the other jaw portion 10 extending below the portion 9 are arranged symmetrically, their tip end faces are opposed to each other, and an open portion 11 is formed between the opposed portions.

  In the handrail belt 3, the belt-like portion 9 rides on the handrail rail 4, the jaw portions 10 on both sides hold the heel portions 7 on both sides of the handrail rail 4, and the end surfaces of the jaw portions 10 on both sides are the handrail rail 4. It is slidably mounted on the handrail rail 4 in a state close to the side surface of the main portion 6.

  FIG. 3 shows an attachment / detachment tool 15 for attaching / detaching the handrail belt 3. FIG. 3A is a side view of the removal tool 15, and FIG. 3B is a front view of the removal tool 15. The detachable tool 15 has a grip portion 16 for gripping with a hand, a straight shaft portion 17 extends at a right angle from an intermediate portion of the grip portion 16, and further bends in a hook shape from a tip portion of the straight shaft portion 17. The curved portion 18 extends, and a spherical portion 19 is integrally formed at the tip of the curved portion 18.

  The curved portion 18 includes a root section 18a extending from the straight shaft section 17, a bent section 18b extending from the root section 18a and bending in an arc shape, and a tip section extending from the bent section 18b. 18c, and a spherical portion 19 is formed at the tip of the tip section 18c. The root section 18a and the tip section 18c extend substantially linearly. For example, the root section 18a is inclined at an angle θ of about 25 ° with respect to the central axis of the straight shaft portion 17, and the curvature radius of the curved section 18b. R is about 15 mm.

And, with the central axis of the straight shaft portion 17 as a reference, the root section 18a and the bent section 18b of the bending section 18 are arranged on one side, and most of the tip section 18c is arranged on the other side, The tip section 18c extends obliquely downward and extends toward the arrangement side of the grip 16. Further, the grip portion 16 is a metal round bar having a diameter of about 12 mm, the straight shaft portion 17 and the curved portion 18 are metal round bars having a diameter of about 6 mm, and the tip of the curved portion 18 is tapered to decrease in diameter. The spherical portion 19 is a metal sphere having a diameter of about 6 mm.

  A procedure for removing the handrail belt 3 from the handrail rail 4 by using the detachable tool 15 will be described with reference to FIGS. 4 and 5. First, an operator grasps the grip portion 16 of the detachable tool 15 by hand, and as shown in FIGS. 4 (A) and 5 (A), the spherical portion 19 at the tip of the detachable tool 15 is moved from one side of the balustrade 2. It is directed toward the gap between the side surface of the main portion 6 of the handrail rail 4 and the end surface of the jaw portion 10 of the handrail belt 3, and the tip section 18 c is formed on the jaw portion 10 as shown in FIG. The ball portion 19 is pushed into the gap against the elastic force, and the spherical portion 19 is protruded inside the jaw portion 10.

  When the distal end section 18c of the detachable tool 15 is pushed into the gap between the side surface of the main portion 6 of the handrail rail 4 and the end surface of the jaw portion 10 of the handrail belt 3, the distal end portion of the detachable tool 15 is moved to the jaw portion 10. The removal tool 15 is bent in a hook shape on the tip side, so that when the tip section 18c is oriented from the bottom to the top, the straight shaft portion 17 is moved. Accordingly, the tip section 18c is moved between the side surface of the main portion 6 and the end surface of the jaw portion 10 of the handrail belt 3 by gripping the grip portion 16 and pulling up the detaching tool 15 obliquely upward. It is possible to push in easily and smoothly to protrude the spherical portion 19 at the tip of the jaw portion 10 to the inside. And since the spherical part 19 is provided in the front-end | tip of the front-end | tip area part 18c, the jaw part 10 of the handrail belt 3 is not damaged.

  In the conventional removal tool, the tip is bent at a right angle with respect to the straight shaft portion. Therefore, when the bent portion of the tip is directed from the bottom to the top, the straight shaft portion is almost horizontal, and thus the straight shaft portion is It is difficult to push up the bent part while holding the grip part, and it is necessary to push up by placing the hand on the lower end side of the bent part, which is cumbersome, inefficient and laborious End up.

  On the other hand, in the detachable tool 15 according to the embodiment of the present invention, the tip section 18c can be easily and efficiently removed by simply pulling the detachable tool 15 obliquely upward with the hand holding the grip portion 16 as described above. 6 can be pushed into the gap between the side surface of the handrail belt 3 and the end surface of the jaw portion 10 of the handrail belt 3 to project the spherical portion 19 into the inside of the jaw portion 10.

  After projecting the spherical portion 19 to the inside of the jaw portion 10, as shown in FIG. 4C, the straight shaft portion 17 is pushed downward to shift to a substantially horizontal state. As a result, the leading edge of the jaw 10 enters the inside of the bending portion 18 of the detachable tool 15, and the holding edge is held by the bending portion 18 of the leading edge of the jaw 10.

  From this state, the removal tool 15 is pulled toward the outer side of the side edge of the handrail belt 3. Thereby, one jaw part 10 of the handrail belt 3 is elastically deformed in a direction away from the main part 6 of the handrail rail 4, and the opening part 11 expands. Furthermore, from this state, as shown in FIG. 4D, the straight shaft portion 17 is directed obliquely upward, and the removal tool 15 is pulled obliquely upward. Thereby, the jaw part 10 is deformed so as to expand more elastically, and the jaw part 10 is detached from the collar part 7 of the handrail belt 3. While maintaining this state, the removal tool 15 is moved along the longitudinal direction of the handrail belt 3 as shown in FIG. By this movement, the jaw part 10 of the other part of the handrail belt 3 is pushed by the attaching / detaching tool 15 and sequentially detached from the collar part 7 of the handrail rail 4.

  By such an operation, the jaw portion 10 on one side of the handrail belt 3 in the portion extending over the required section of the handrail belt 3 is detached from the collar portion 7 on one side of the handrail rail 4. Thereafter, the jaw portion 10 on the other side of the handrail belt 3 in the required section is manually removed from the flange portion 7 on the other side of the handrail rail 4. At this time, since the jaw portion 10 on one side of the handrail belt 3 has already been detached from the flange portion 7 on the one side and is loosened, the jaw portion 10 on the other side can be easily removed manually.

  Thus, the handrail belt 3 and the handrail rail 4 in the required section are completely separated by removing the jaws 10 on both sides of the handrail belt 3 from the flanges 7 on both sides of the handrail rail 4 over the required section. Thus, operations such as maintenance and inspection for the handrail belt 3 and the handrail rail 4 can be performed.

  By the way, when the jaw part 10 of the handrail belt 3 is pulled outwardly from the side edge of the handrail belt 3 by the attaching / detaching tool 15 and elastically deformed, the attaching / detaching tool 15 according to the embodiment of the present invention uses the jaw part 10. The edge portion on the tip side is disposed inside the bending portion 18 and is held by the bending portion 18, so that the catch between the detachable tool 15 and the jaw portion 10 is stabilized, and the detachable tool 15 The jaw portion 10 is not inadvertently detached from the curved portion 18, and therefore the jaw portion 10 can be elastically deformed accurately.

  In the conventional detachable tool, since the straight shaft portion and the bent portion are both linear and have an L shape that intersects each other at right angles, when the detachable tool is pulled to elastically deform the jaw portion, the jaw portion 10 May be detached from the bent portion, and it may be difficult to deform the jaw portion 10 accurately.

In the detachable tool 15 according to the embodiment of the present invention, there is no such fear, and the jaw portion 10 can be separated from the handrail rail 4 by elastically deforming the jaw portion 10 efficiently and accurately. .

  On the other hand, when attaching the handrail belt 3 to the handrail rail 4, the reverse operation of removal may be performed. That is, first, the jaw portion 10 on one side of the handrail belt 3 is manually fitted into the flange portion 7 on one side of the handrail rail 4, and then the curved portion of the attachment / detachment tool 15 on the edge of the distal end side of the jaw portion 10 on the other side. 18, the jaw part 10 is fitted and attached to the flange part 7 of the handrail rail 4 while the jaw part 10 is pulled and deformed so as to expand elastically by the removal tool 15.

  Although the escalator handrail belt has been described in the above embodiment, the embodiment of the present invention can be applied not only to the escalator handrail belt but also to other passenger conveyor handrail belts such as moving walkways. is there. That is, the said embodiment was shown as an example and is not intending limiting the range of invention. The novel embodiment of the present invention can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the spirit of the invention. The embodiments and modifications thereof are included in the scope and gist of the invention, and are included in the invention described in the claims and the equivalents thereof.
