Abstract

PROBLEM TO BE SOLVED: To reduce frictional resistance to a handrail, and maintain moving speed of the handrail by forming plural recessed/projecting parts extending in the moving direction of the handrail on a slidingly movable surface of the handrail in a guide member. SOLUTION: Plural recessed/projecting parts 11a extending in the moving direction of a handrail 3 are integrally formed on a slidingly movable surface of the handrail 3 of a guide member 11. In this way, when the recessed/ projecting parts 11a are arranged in the guide member 11, the contact area to the guide member 11 on the reverse of the handrail 3 is sharply reduced, and frictional resistance of the guide member 11 to the handrail 3 is fairly reduced. Therefore, moving speed of the handrail 3 can be maintained almost equal to moving speed of a step over a long period of time.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a handrail guide device for a conveyer such as an escalator and a moving walkway, and more particularly to a reduction in sliding friction of a handrail.

[0002]

2. Description of the Related Art FIG. 6 is a schematic diagram showing an example of a conventional escalator. In the drawing, 1 is a step connected endlessly, 2 is a balustrade standing upright on both sides of the outward path of step 1, 3 is a handrail circulating along the balustrade 2 at substantially the same speed as in step 1, Reference numeral 4 denotes a driving device for driving the handrail 3. A handrail guide device (not shown) for guiding the handrail 3 is provided above the balustrade 2.

FIG. 7 shows a driving device 5 of a different type from that of FIG.
FIG. 5 is a view showing an escalator having a slash, and the drive device 5 drives the handrail 3 in synchronization with step 1 on the return side.

[0004]

In the conventional escalator constructed as described above, the frictional resistance between the handrail 3 and the guide device increases with time due to the contamination of the handrail 3 and the like, and the drive is stopped. When the frictional force of the devices 4 and 5 with respect to the handrail 3 approaches, there is a problem that it is difficult to move the handrail 3 with respect to the step 1 at substantially the same speed.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems, and can reduce the frictional resistance to the handrail and maintain the moving speed of the handrail. It is an object to obtain a handrail guide device for a conveyor.

[0006]

According to a first aspect of the present invention, there is provided a handrail guide device for a man conveyor provided on a balustrade of the man conveyor and provided with a guide member for guiding the handrail. In the above, the sliding surface of the handrail in the guide member is formed with a plurality of uneven portions extending along the moving direction of the handrail.

[0007] A handrail guide device for a man conveyor according to a second aspect of the present invention is such that the concave and convex portions are formed integrally with the guide member.

According to a third aspect of the present invention, there is provided a handrail guide device for a man conveyor having a guide member main body and a resin low friction member adhered to the guide member main body and having an uneven portion formed on a surface thereof. The guide member is used.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. Embodiment 1 FIG. FIG. 1 is a sectional view of a handrail guide device according to Embodiment 1 of the present invention, and FIG. 2 is a perspective view showing a guide member of FIG.

In the drawings, reference numeral 11 denotes a metal guide member fixed to the upper end of the balustrade 2 (FIGS. 6 and 7) and guiding the handrail 3. The guide member 11 is provided on the sliding surface of the handrail 3 of the guide member 11. Is formed integrally with a plurality of uneven portions 11a extending along the moving direction of the handrail 3.

In such a handrail guide device,
The provision of the uneven portion 11a on the guide member 11 greatly reduces the contact area of the back surface of the handrail 3 with the guide member 11, and the frictional resistance of the guide member 11 to the handrail 3 is considerably reduced. Therefore, the moving speed of the handrail can be maintained substantially the same as the moving speed of step 1 for a long period of time.

Embodiment 2 FIG. In the above example, the guide member 11 made of metal is shown. However, for example, as shown in FIG.

Embodiment 3 FIG. 4 is a perspective view showing a handrail guide device according to Embodiment 3 of the present invention. In the drawing, 13 is a guide member body fixed to the upper end of the balustrade 2 (FIGS. 6 and 7) and guiding the handrail 3;
Reference numeral 14 denotes a low friction member made of synthetic resin, which is adhered to the sliding surface of the handrail 3 in the guide member body 13 and has a plurality of uneven portions 14a extending along the moving direction of the handrail 3 formed on the surface. The low friction member 14 has a thickness of, for example, about 1 to 1.5 mm and has sufficient durability. FIG. 5 is a perspective view showing the low friction member 14 of FIG.

As described above, by attaching the low friction member 14 to the guide member main body 13, the handrail 3
Frictional resistance can be reduced, and a margin can be provided for an increase in frictional resistance due to contamination or the like. In addition, by using the low friction member 14 which is another member, it can be applied to an existing man conveyor.

[0015]

As described above, the handrail guide device for a man conveyor according to the first aspect of the present invention has a plurality of uneven portions extending along the moving direction of the handrail on the sliding surface of the handrail of the guide member. Is formed, the frictional resistance to the handrail can be reduced, and the moving speed of the handrail can be maintained for a long period of time.

In the handrail guide device for a man conveyor according to the second aspect of the present invention, since the uneven portion is formed integrally with the guide member, the frictional resistance to the handrail can be reduced without increasing the number of parts.

The handrail guide device for a man conveyor according to the third aspect of the present invention is applied to an existing man conveyor because a low friction member made of resin having an uneven portion formed on its surface is adhered to the guide member body. be able to.
