Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a guide device for an escalator moving handrail.

[0002]

2. Description of the Related Art Conventionally, a technique for restricting the lateral movement of a moving handrail of an escalator is disclosed in Japanese Patent Laid-Open Publication No. Sho 59-48381, in which a moving handrail is provided inside a housing provided with a roller shaft of a guide roller outside the moving handrail. A bearing supported on a bearing is disclosed.

However, in order to increase the cost by adding a guide roller, a technique for restricting the lateral direction of the moving handrail without using the guide roller has been developed, and the technique without using the guide roller is shown in FIGS. This will be described with reference to FIG.

In FIG. 3, reference numeral 1 denotes an endless moving handrail;
Is a frame, and 3 is a driving device of the moving handrail 1. The driving device 3 includes a plurality of driving rollers 3a on the return side of the moving handrail 1.
The moving handrail 1 is driven by being pressed between the moving handrail 1 and the pressure roller 3b. A guide roller device 4 for regulating the lateral movement of the moving handrail 1 is provided before and after the driving device 3. As shown in FIG. 4, the roller device 4 has an elongated hole 4a in the frame 2.
The receiving roller 4c is axially supported by a bracket 4b which is screwed through the bracket, and the traveling direction of the moving handrail 1 and the axial direction of the receiving roller 4c are mounted at a right angle. 3a comes into contact with the ear 1a of the moving handrail 1, and the ear 1a is worn by friction. Therefore, the bracket 4b is attached using the elongated hole 4a, and the angle between the circulating direction of the moving handrail 1 and the axial direction of the receiving roller 4c. Is adjusted by plus or minus several degrees from 90 degrees, thereby moving the moving handrail 1 in the lateral direction to prevent the drive roller 3a from contacting the ear 1a.

[0005]

In the above prior art, the angle between the traveling direction of the moving handrail 1 and the axial direction of the receiving roller 4c is adjusted so that the moving handrail 1 travels, and the ear of the moving handrail 1 is driven by the driving roller 3c. It was necessary to check the presence or absence of contact, and if necessary, it was necessary to repeat the angle adjustment again, which was a laborious and time-consuming operation. Furthermore, since a plurality of the guide roller devices are provided, the adjustment operation requires a long time.

SUMMARY OF THE INVENTION An object of the present invention is to provide an escalator moving handrail guide device which can easily adjust the gap between the ear of the moving handrail and the drive roller in a short time.

[0007]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides an endlessly arranged and rotating step, and an endlessly connected moving handrail which rotates in synchronization with the step. An escalator moving handrail guide device including a guide body that fits inside the moving handrail and restricts the movement of the moving handrail in the lateral direction, wherein the guide body contacts one of the inner side surfaces of the moving handrail. It is provided with a rotating portion that can be brought into contact and a holding portion that holds the contacting state.

With this configuration, when the driving roller is in contact with the ear of the moving handrail, the guide body fitted and disposed inside the moving handrail is oriented in the direction of the ear that is in contact with the driving roller. When this is rotated, the guide body presses the inner surface of the moving handrail to move in the lateral direction, so that the gap adjustment work between the drive roller and the moving handrail ear can be performed in a short time.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS. 3 and 4 are denoted by the same reference numerals, and description thereof is omitted.

FIG. 1 is a perspective view of a guide body showing one embodiment of a guide device for an escalator moving handrail according to the present invention.
1 is a front view of a main part of a moving handrail according to an embodiment of the present invention.

In the drawing, a first bracket 5 screwed to a frame 2 near a guide roller device 4 disposed on the frame 2, and an L-shaped second screw screwed to the first bracket The bracket 6 and a guide body 7 screwed to the second bracket 6 are arranged so as to be fitted inside the moving handrail 1. Here, the first bracket 5 is formed by bending a plate body three times at right angles in the same direction, and when one end is screwed to the frame 2, the other end is located above the opening of the moving handrail 1. Further, on one surface of the second bracket 6, a round hole 6a as a rotating portion for screwing the oval guide body 7 and an elongated hole 6b as a holding portion are provided at predetermined intervals. The guide body 7 is also provided with two round holes 7a and 7b at a predetermined interval, and the round hole 7a of the guide body 7 and the round hole 6a and the long hole 6b of the second bracket 6 are provided with bolts (not shown). An elongated hole 6b can be screwed with a nut and has a bolt (not shown) inserted in the round hole 6a of the second bracket 6 as an axis.
The guide body 7 can be rotated only within the range of.

Next, a method of adjusting the distance between the ear 1a of the moving handrail 1 and the drive roller 3a using the guide body 7 of this embodiment will be described.

If the ear 1a of the moving handrail 1 and the drive roller 3a are in contact with each other in FIG.
The bolts and nuts (not shown) attached to the long holes 6b are loosened, and the bolts (not shown) inserted into the round holes 6a of the second bracket 6 are rotated toward the ears 1a around the shafts, so that the drive roller 3a and the ears are rotated. After the gaps 1a and 1b are made substantially equal, the second bracket 6 and the guide body 7 are screwed together with bolts and nuts (not shown).

Here, the material of the guide body 7 is suitably made of synthetic resin nylon. Even if the guide body 7 comes into contact with the ears 1a and 1b and is worn, the abrasion powder of nylon of the guide body 7 causes the ear 1a. , 1b, the initial wear is large, but the wear of the guide body 7 is immediately reduced. Also,
Since the nylon guide body is soft, no noise is generated when the guide body comes into contact with the ears 1a and 1b.

In this embodiment, the guide body 7 has an elliptical structure. However, it is obvious that the guide body 7 may be rectangular or triangular as long as it can contact the ears 1a and 1b of the moving handrail 1.

[0016]

According to the present invention, when the driving roller is in contact with the ear of the moving handrail, the guide body fitted and arranged inside the moving handrail is provided with the guide of the ear which is in contact with the driving roller. When the movable handrail is rotated in the direction, the guide body presses the moving handrail and moves in the lateral direction, so that the gap adjusting operation between the driving roller and the moving handrail ear can be performed in a short time.
