JPS5842380Y2 - Guide for handrail of passenger conveyor - Google Patents

Description

[Detailed Description of the Invention] The present invention relates to a passenger conveyor such as an escalator or an electric road, and particularly relates to a structure suitable for reducing running resistance of a rotating rail.

As shown in FIGS. 1 and 2, a conventional passenger conveyor has a structure in which a parapet 2 is disposed above steps 1 which are arranged in an endless manner and rotate, and a frame 3 and a guide 4 at the upper end of the parapet 2. The most common method is to guide the rail (traveling body) 5 by using the following means.

Since the step 1 and the rail 5 are directly used by passengers, they are required to maintain their aesthetic appearance for a long time and to run smoothly at all times as essential functions.

However, the conventional handrail 5 has the following problems, and a solution to these problems is desired.

That is, the guide 4 is supported at the upper end of the opening of the frame 3 and fixed with a fastening bolt 6, but the guide 4 is also attached to the joint in the longitudinal direction, as shown in FIGS. 3 and 4.
The phenomenon shown in the figure occurs.

This phenomenon of uneven height is caused by a defect when assembling the passenger conveyor, but there is a structural constraint that forces the head 6a and naso 6b of the fastening bolt 6 to separate. This is also due to the problem of not being able to prevent the guide 4 from moving laterally.

The step difference δ caused by the above causes a collision phenomenon as shown by arrows A and B (different depending on the running direction) when the handrail 5 runs, resulting in an increase in the running resistance of the handrail 5.

Such an increase in running resistance may cause problems with the service life of the handrail 5 due to excessive force applied thereto, or may cause discomfort during running due to a collision phenomenon at the step δ portion.

For this reason, although chamfering X has conventionally been applied as a measure to reduce the step difference δ, the actual situation is that the effect is not as expected.

In view of this point, the present invention was made in order to smoothen the joints of the guides 4 so that the handrails 5 can run smoothly.

The present invention is directed to a device equipped with steps that are arranged in an endless manner and rotate, a handrail that rotates synchronously with the steps, a frame that guides and supports the handrail, and a guide. The guide is provided with a groove whose width decreases toward the guide, and is configured to fit into the groove, and is provided with a fastening guidela that is integrally constructed so as to straddle the joint portion of the guide.

An embodiment of the present invention will be described below based on the drawings.

5 and 6, the configuration of the parapet 2, frame 3, band rail 5, etc. is the same as the conventional one, so illustration can be omitted; A slope z1 with an upper width W1 and a lower width W2 near the center of the upper surface
It is characterized by providing a long fastening guide 8 having an upper width Wa, a lower width wb and a slope Za in this part, and integrally straddling the joint part of the guide 7. There is.

Here, the relationship between each width is W1÷WasW2inW
b s Z 1 and Z a are approximate, so that the fastening guide 8 can be inserted snugly into the groove 7a.

The fastening guide 8 is provided with a hole 8a, as required, through which a fastening bolt (similar to the conventional fastening bolt 6) passes.

1. To explain how to assemble the guide 7 based on this embodiment, place the guide 7 on top of the frame 3,
Further, after placing the fastening guide 8 in the groove 7a from above, a fastening bolt is inserted into the hole 8a and tightened.

Here, since the groove 7a and the fastening guide 8 engage with each other with the slopes Z1 and Za, respectively, by providing the groove 7a accurately at the center of the guide 7, the guides 7 divided in the longitudinal direction can be separated from each other in the longitudinal direction of the fastening guide 8. The left and right positions are corrected along the lines.

In this way, each guide γ is positioned along the linear curve of the fastening guide 8, so there is no difference in level between the guides as in the conventional case.

According to the present invention discussed above, the band rail 5 runs smoothly and has great effects in terms of service life and riding comfort.
