Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] This invention relates to a device for guiding a slider of a passenger conveyor.

[Conventional technology]

A moving child slide guide is provided on the railing of a passenger conveyor such as an escalator or a moving walkway, and the moving child slide is guided by the guide rail attached to the guide rail.

As is well known, the cross section of the slider is C-shaped.
They are connected in an endless manner, and the inside of the 0 character above fits into the guide rail. However, when assembling the slider slide into the guide rail, the ears of the slider slide are forced open and pushed into the guide rail. Therefore, there is a risk that the slider seat υ may be damaged or that the difference between the inner width of the slider seat and the outer width of the guide rail becomes large, making it easier for the slider seat υ to come off.

Therefore, in order to improve this, for example,
A method as shown in Publication No. 35 has been proposed. A device similar to this will be explained with reference to FIGS. 4 to 6. Note that an escalator is shown as a passenger conveyor.

In the figure, (1) is a sliding slide guide made of a longitudinal member whose both ends are fixed to a truss (not shown), and (2) is a slide guide whose lower end is fixed to the truss and stands upright, and whose upper end is protected by a rubber plate, etc. An inner plate made of a transparent glass plate covered with a plate (3) and inserted into the inner circumference of the slider guide (1).
4) and screw seat (5) to move the slider guide (1)
is fixed to. (6) is a guide rail consisting of a longitudinal member disposed along the outer periphery of the slider guide (1) and a guide body (6A), (6A) divided into two parts along its center line; 6a), (6a) are guide bodies (6
A) ridges formed on the inner periphery of (6A) and engaged with the outer periphery of the slider guide (1), (6b), (6'b)
) are formed at the opposing parts of the guide bodies (6A), (6A), and the slopes i, j'y) approaching each other from the outside to the inside of the guide bodies (6A), (6A) are the slope surfaces (6b
), a slider formed in a wedge shape with an inclined surface similar to (6'b) and arranged between inclined surfaces (6b), (6b) at an appropriate interval, (8) is a slider guide. A fastener (bolt) screwed into the slider (7) from the inner circumference of (1)
, (9) is formed into a C-shaped cross section and is a guide rail (6).
a moving child slide whose movement is guided by engagement with the (LIll);
is a washer for preventing the bolt (8) inserted into the bolt (8) from slipping out.

The conventional handrail guide device for a passenger conveyor is constructed as described above, and when installing the slider (9), loosen the bolt (8) and raise the slider (sufficient force). (6A
), (6A) close to each other to create a guide, trail (
After reducing the width dimension of 6), attach the slider slide (9). After installing the slider 9 (9), tighten the bolt (8) to move the slider (7) to the inclined surface (61: +
), (6 to +). Along with this, the guide bodies (6A), (6A,) move away from each other, and the protrusion (6a).

(6a) comes into contact with the mover-less guide (1) and stops.

Now, while the slider slide (9) is operating, the guide rail (
6) Accidents such as falling off are prevented.

[Problem that the invention seeks to solve]

Conventional handrail guide systems for passenger conveyors such as those described above create difficulties during subsequent replacement of the slider. In other words, when inspecting escalator maintenance, when replacing the slider sheath (9) due to dirt or damage, or when replacing the guide rail (6) due to wear, the slider sheath (9) must be replaced with the guide rail. (6
) must be removed from At this time, if the bolt (8) is loosened, the slider (7) will stop lifting, but only a gap will be created between the slider (force) and the inclined surfaces (6b), and the guide body ( 6A), (6A) do not move, and the guide rail (
6) The width dimension does not become smaller. Therefore, it is necessary to use a special tool for removing the slider bracket (9), instead of requiring the removal of the slider bracket (9), which increases the time required for maintenance and inspection. There is a problem that there is a risk of damaging the baby sushi (9).

This invention was made in order to solve the above-mentioned problems, and is a passenger conveyor that makes it easy to attach and detach the slider slide during maintenance and inspection even after the slider slide is in operation, and to shorten the work time. Consideration will be given to providing handrail guide equipment.

[Means for solving problems]

In the handrail guide device for a passenger conveyor according to the present invention, a first engaging portion is provided on opposing portions of a guide body divided into two parts, each having an inclined surface that approaches each other from the outside to the inside of the guide body at a distance. A slider having a second engaging part that fits into the first engaging part is arranged, and this slider is fastened to the fixed part by a fastener.

[Effect]

In the handrail guide device for a passenger conveyor according to the present invention, since the second engaging portion of the slider and the first engaging portion of the guide body are fitted into each other, the slider is lifted by the fastener. Accordingly, the guide bodies move closer to each other, and the diameter of the guide rail becomes smaller.

[Example] Figures 1 to 4 are diagrams showing an example of the present invention.
) to (5), (81, and (9) are the same as the conventional device.
The guide bodies (6A) are formed at intervals on opposite sides of the guide bodies (6A).

The first engaging body (6A) has inclined surfaces (6t+) and (6b) that approach each other from the outside to the inside, and in this embodiment, a dovetail groove-shaped recess is used. (7) is a recess (6c) and is arranged at a level corresponding to the recess (6c).

The second engaging body ('7a) that fits into (6C), ('
In this embodiment, a protrusion is used as the second engaging body ('7a). That is, the recess (6c) and the protrusion (7a) are the same. Slope (
6b), and are able to slide vertically relative to each other, but cannot be separated laterally. The slider (7) is fastened to a fixed part, and here the slider guide (1) is used as the fixed part.0 In the handrail guide device for a passenger conveyor configured as described above, is a slider (the force is formed in a wedge shape υ,
By rotating the bolt (8), it moves up and down, the guide bodies (6A) and (6A) move laterally, and the width dimension of the guide rail (6) changes.0 Figure 1 shows the state when the escalator is in operation. , the slider (7) is in the lowered position, the guide bodies (6A), (6A) are at the protrusions (6a), (6a
) comes into contact with the slider guide (1), so that the guide rail (6) maintains its normal width dimension. In addition, the guide bodies (6A) and (6A) are connected to each other by engaging the slider (force protrusion (7a)) in the recess (6C). Move child to (9)
), use the bolts (8) as shown in Figure 3.
), the slider (7) is raised with the protrusion (7a) guided by the recess (6C), and the guide body (6A
), (6A) are attracted to each other, and the guide rail (6A)
) becomes smaller 0 At the same time, the slider (7) actively pushes out the slider slide (9), so the slider (9)
The guide bodies (6A) and (6A) can be easily removed from the slider guide (1).
Recesses (6C) and (60) are provided, and a projection (
7a) l (7a) is shown, but by reversing this, protrusions are provided on the guide bodies (6A), (6A), a recess is provided on the slider (7), and the two are fitted. 0Also, although the explanation has been made as being applied to an escalator, it is obvious that it can also be applied to moving and walking.Q [Effects of the Invention] As explained above, this invention is applicable to The guide rail that guides the child's sushi is constituted by a guide body divided into two parts in the longitudinal direction, and each of the opposing parts has an inclined surface that approaches each other from the outside to the inside of the guide body with a gap between them. a first engaging portion is provided, a slider having a second engaging portion that fits into the first engaging portion is arranged;
This slider is fastened to a fixed part using a fastener.

As a result, even after the slider slide υ is in operation, it is easy to attach and remove the slider slider during maintenance and inspection, and the working time can be shortened.
