DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tool for removing a moving handrail such as an escalator or a moving walkway (hereinafter referred to as an escalator or the like) from a guide rail.

[0002]

2. Description of the Related Art In an escalator 1 shown in FIG. 2, after installation of an escalator, adjustment or maintenance of a driving device (not shown) of a moving handrail 2 or repair and repair of the moving handrail 2 is performed.
At the time of replacement, it is necessary to remove the handrail 2.

Conventionally, the movable handrail 2 is removed from the guide rail 4 of the deck board 3 by forcibly expanding the jaw 2a of the movable handrail 2 outward from the state shown in FIG. The gap G between the jaw portion 2a of the moving handrail 2 and the deck board 3 as shown in FIG.
The driver 5 was forcibly put in and the moving handrail 2 was removed.

[0004] However, the moving handrail 2 is designed so that it does not easily come off the guide rail 4 during operation of the escalator.
With a certain rigidity, the jaws 2a of the moving handrail 2 have a structure in which the jaws 2a enter a predetermined dimension below the guide rails 4. Therefore, when performing by hand, two adults have to do it by hand. It took time and labor. The method of removing the moving handrail 2 by inserting the driver 5 or the like into the gap G between the jaw portion 2a and the deck board 3 has a disadvantage that the moving handrail 2 itself, the guide rail 4, and the like are damaged.

For this reason, a moving handrail 2 such as an escalator is used.
Conventionally, various tools have been proposed so as to enable easy removal of the tool. 4 (a) and 4 (b) show an example in which the moving handrail 2 is detached by using different tools. In each case, the tip of the tool is pressed against the jaw 2a of the moving handrail 2, and Moving railing 2 utilizing this principle
To try to remove it.

[0006]

The tool 1 shown in FIG.
In the case of 0, the gripper 12 attached to the tip of the arm 11 is pressed against the moving handrail 2 as shown in FIG. The moving handrail 2 is removed from the guide rail 4. However, since the fulcrum 13 is located on the upper surface of the moving handrail 2, the jaw portion 2 a of the moving handrail 2 does not open well, and the moving handrail 2 is removed from the inner surface of the gripping portion 12. Since the surface is rubbed, the surface of the moving handrail 2 is scratched, and an indentation is left at the contact portion of the fulcrum 13.

Next, in the case of the tool 20 shown in FIG.
Since the fulcrum 22 of the J-shaped hook 21 is the upper surface of the decorative rubber of the moving handrail 2, it is easy to make an indentation or a scratch.
The small protrusion 21a at the tip of the moving handrail 2 rubs the surface of the jaw portion 2a of the moving handrail 2, so that the surface of the moving handrail 2 is easily damaged. In addition, since the jaws 2a of the handrail 2 cannot be fully opened, there is a disadvantage that workability is not very good.

The present invention has been made in view of the above points, and an object of the present invention is to provide a tool which is less likely to damage a moving handrail, a guide rail, and the like, and has excellent workability.

[0009]

According to the present invention, there is provided (1) a bifurcated outwardly extending plate provided at the tip of an arm, and the bifurcated first plate is bent upward at the tip. A moving handrail removal tool such as an escalator having a bent portion and a forked second plate having a plurality of projections on a lower surface. (2) A bifurcated outwardly extending plate is provided at the tip of the arm, and the bifurcated first plate has a bent portion bent upward at the tip, and a bifurcated second plate is provided. A moving handrail removal tool, such as an escalator, provided with a plate that is curved upward, has a plurality of protrusions on the lower surface, and is movably provided in the longitudinal direction of the arm. It is.

[0010]

If the above-mentioned method is used or if the above-mentioned tool is used, the moving handrail moves upward after the jaw portion is opened and easily detaches from the guide rail.

[0011]

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is an overall perspective view showing an example of a moving handrail removal tool according to the present invention, and FIG. 5 is an explanatory diagram for explaining how to handle the tool shown in FIG.

In the drawings, the same reference numerals as in FIGS. 2 to 4 denote the same parts, but reference numeral 30 denotes a moving handrail removal tool according to the present invention, which comprises an arm 31, an action plate 32, and a fulcrum plate 33. . The working plate 32 is the arm 31
The working plate 32 has a bent portion 32a which is bent upward, and a protrusion 32b is provided on the upper surface near the bent portion 32a. It has. One end of the fulcrum plate 33 has a screw 33 on the upper surface of the working plate 32.
a, it is screwed so as to be movable in the longitudinal direction of the arm 31 and is bent upward so as to enclose the moving handrail 2, and a projection 3 is provided on the lower surface.
3b, 33c, and 33d. Note that the tools 30 may all be formed as a single unit.

Next, a method of removing the moving handrail 2 from the guide rail 4 of the deck board 3 using the tool 30,
That is, how to use the tool 30 will be described. First, the bent portion 32a of the working plate 32 is securely inserted between the deck board 3 and the jaw portion 2a of the moving handrail 2 to bend the bent portion 3a.
After the jaws 2a of the moving handrail 2 are gripped by the 2a and the protrusions 32b, the fulcrum plate 33 is positioned by the screws 33a such that the protrusions 33b are in contact with the side of the moving handrail 2, and then the arm 31 is moved to the position shown in FIG. As shown in FIG. 5 (a), when the arm is rotated in the direction of the arrow, a relatively rigid portion in contact with the projection 33b serves as a fulcrum, and the jaw 2a of the moving handrail 2 receives the force from the bent portion 32a to move the jaw 2a of FIG. Move to the open state as shown in).

Thereafter, when the arm 31 is further rotated in the direction of the arrow shown in FIG. 5 (b), the portion in contact with the projection 33c becomes a fulcrum (ie, the fulcrum moves), and the bent portion 3
When the jaw 2a of the moving handrail 2 moves upward by receiving a force from 2a, and furthermore, the arm 31 is rotated in the direction of the arrow,
This time, the fulcrum moves to the portion where the protrusion 33d contacts, and FIG.
The jaws 2a of the moving handrail 2 are completely disengaged from the guide rails 4 as shown in FIG.
a slides out from the bent portion 32a and guide rail 4
Will be on top.

In the case of the escalator shown in FIG. 2, such a detaching operation can be performed most easily by performing the operation at the downward curved portion indicated by X. In this case, the moving handrail 2 can be detached from the guide rail 4 at only one position. For example, the entire moving handrail can be easily removed from the guide rail 4 by inserting a stick between the guide rail 4 and the moving handrail 2 and moving the escalator in the longitudinal direction. There is no need to repeat the removal operation by shifting the work in the longitudinal direction.

Recent balustrades such as escalators, in particular, deck boards 3 for supporting guide rails 4 have been proposed to have various structures in view of the presence or absence of lighting devices and design problems. Obviously, any structure of deck board can be used.

[0017]

As described above, according to the present invention, when the moving handrail is removed, a force is applied while moving the fulcrum from the side surface to the upper surface of the moving handrail with the portion facing the deck board as the point of action. Because of the method, the jaws of the moving handrail are first opened and then moved upward, so that they can be easily removed. Also, since the fulcrum moves, there is almost no fear of indenting or scratching. On the other hand, if the tool according to the present invention is used, the above-described removal method can be performed very naturally, and not only can the above-described effect be exhibited, but also the workability of the removal operation can be significantly improved. Further, if the forked second plate of this tool is configured to be movable relative to the arm (the forked first plate may be configured to be movable relative to the arm), there are various types. Since the shape of the handrail can be adjusted in advance, the workability is not impaired.
