Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a handrail for a passenger conveyor such as an escalator or an electric road, and a method for assembling the same, and particularly to a handrail for a passenger conveyor with a simplified structure and an assembly method thereof. Regarding the method.

[Conventional technology]

Passenger conveyors have been widely used and have become widely used as essential transportation equipment within buildings, but recently there are various needs for transportation equipment such as energy saving, safety, and lightness of design.

As shown in Fig. 1, the conventional passenger conveyor has a rotating body consisting of steps 1 and handrails 2 that are arranged in an endless manner and rotates, and stationary bodies such as a handrail 3 and a main body frame 4. , all these parts are supported by the building floor F.

The details of the parapet 3 include the glass panel 5 supported by the main body frame 4 and the inner deck 6, as shown in Figures 1 to 3.
, a guide 9 for guiding the handrail 2 on the lower sap material of the parapet such as the outer deck 7 and the skirt guard 8, and on the upper side of the glass panel 5. Guide frame 10. Sapwood on the parapet for lighting equipment 11 and the like is provided. Inside the guide frame 10 (generally made of methine-free steel), there is a packing 12 that protects the glass panel 5, a support 15 that holds the glass panel 5, and a bolt 16 that is fastened to the support 15. A push plate 17 is provided for finally fixing the glass panel 5. The lamp 13 of the lighting fixture 11 and a cover 14 covering the lamp 13 are supported at the lower part of the support 15.

Here, the dimensional relationship of the sap material on the balustrade will be explained. The guide 9 on the upper side is made up of a decorative rubber part 2a and a cotton canvas part 2b, and is dimensioned to engage with the inner periphery of the handrail 2 formed into a C-shaped cross section, and is fixed to the guide frame 10 with a bolt (not shown). ing. Next, the guide frame 10 has a height h that is 2 to 3 times the size ratio to the height ha of the handrail 2, and the width direction is fla dimension from the side edge of the handrail 2 to the outside. , it is normal for the 01 dimension (generally 10 to 50 mm for both Ra and flb) to protrude inward, and the Ωa dimension side is used for storing the lighting fixture 11, and the Oh dimension side is used for gripping the glass panel 5. There is.

[Problem to be solved by the invention]

The handrail of the conventional passenger conveyor mentioned above is a guide frame 10.
was so large that even if the lighting fixture 11 was removed, it would still be at the position shown by the imaginary line Z, and the height h from the handrail 2 was more than twice the height h& of the handrail 2. Attachment of such a large guide frame 1o to the glass panel 5 must be performed upward from the outside of the glass panel 5 (the side opposite to the step), which is extremely troublesome.

In addition, U.S. Patent No. N is available for a smaller guide frame.
There is a parapet of a passenger conveyor described in α3,989,133. However, this configuration has a problem in that the connection between the guide frame and the glass panel becomes loose due to vibrations during operation of the passenger conveyor and deterioration of the packing.

An object of the present invention is to provide a handrail for a passenger conveyor and a method for assembling the same, which facilitates the attachment of a guide frame to a transparent panel and allows the attachment to be carried out firmly.

[Means to solve the problem]

In order to achieve the above-mentioned object, the present invention forms a pair of extending parts in a guide frame, the distance being narrower in the extending direction and narrower than the thickness of the peripheral edge of the transparent panel; The peripheral edge portion of the transparent panel was inserted between the extending portions, and the extending portions were fixed so that the intervals were substantially parallel.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 4 to 7.

The drive mechanism of the rotating step, the structure of the main body frame, and the structure of the lower parapet member including the inner and outer decks are the same as the conventional ones, so their explanation will be omitted. The configuration of the guide frame 19 that is fixed to the peripheral edge and supports the handrail 2 is significantly different from the conventional one.

That is, the guide frame 19 is provided continuously over the entire length of the glass panel 18, and when looking at its cross-sectional shape, it has a support part 20 extending horizontally and an extension part extending downward from the support part 2o. 21. This guide frame 1
2 along the longitudinal direction at symmetrical positions on the upper surface of the support part 20 of 9.
Engagement grooves G are provided in parallel, and a pair of walls 22A are provided on the lower surface of the support portion, the distance becoming narrower in the extending direction.
.

An extending portion 21 consisting of 22B is formed. and,
The pair of walls 22A and 22B form an inverted U-shaped fitting groove 23 between the supporting portion 20. Incidentally, the distance W2 between the pair of walls 22A and 22B on the supporting part 20 side is
is larger than the thickness of the glass panel 18 and slightly smaller than the thickness Wl when the packing 24 is attached to the peripheral edge, and the gap W8 on the tip side is smaller than the gap W2 on the support part 20 side. ing.

In addition, the guide frame 19 is provided with two guides 25 made of a plastic material such as nylon having a low coefficient of friction in order to reduce the sliding resistance of the handrail 2. This guide 25 has an upper end 25A
is formed so that it engages with the engagement groove G of the support part 20, and the lower end 25B abuts the lower end 21E of the extension part 21,
Furthermore, it has a curved portion 25G that faces the inner peripheral curved surface of the handrail 2. And the lower end 25B of the guide 25
The opening of the handrail 2 and the glass panel 18
It is placed to close this gap.

The two walls 22A, 2 of the guide frame 19
The peripheral edge of the glass panel 18 is inserted through the packing 24 into the fitting groove 23 formed by the support portion 20 and the glass panel 2B. By inserting the glass panel 18, the wall 22A,
The distance W3 on the tip side of 22B is the distance Wz on the support part 20 side.
It is pushed out until it is almost the same as the Thereby, a glass panel 18 is provided on the tip side of the pair of walls 22A, 22B.
A reaction force is generated which clamps the guide frame 1.9, and this reaction force fixes the guide frame 1.9 to the peripheral edge of the glass panel 18.

As explained above, the distance between the pair of walls 22A and 22B of the guide frame 19 is made narrower in the extending direction, and by inserting the glass panel 18, the wall 22A and 22B are
Since the walls 2A and 22B are made to be approximately parallel, a clamping force is generated on the extending end sides of the walls 22A and 22B, and this clamping force prevents vibrations and deterioration of the packing 24 when the passenger conveyor is in operation. Even if the guide frame 19
The adhesion to the glass panel 18 can be maintained for a long period of time.

If the pair of walls 22A and 22B are parallel to each other, the insertion of the glass panel 18 will widen the distance between the extending ends of the walls, and a clamping force will be generated at the base of the walls. Therefore, in extreme cases, the extending end of the wall may float away from the glass panel 18 side. In this way, if the guide frame 19 is fixed to the glass panel 18 by the clamping force generated near the root of the wall, the guide frame may come off due to vibration during operation of the passenger conveyor or deterioration of the packing. In order to eliminate the warping of the extending end of the wall when inserting the glass panel, it is necessary to increase the rigidity of the pair of walls, and in order to do so, it is necessary to increase the rigidity of the pair of walls as well as the member that connects the walls. Therefore, the guide frame must be made larger.

In the embodiment of the present invention, the extending ends of the pair of walls 22A and 22B are expanded and made parallel by inserting the glass panel 18 to obtain the clamping force, so there is no need to increase the thickness of each part. Moreover, since the support part 20 and the extension part 21 of the handrail 2 are brought close together, the guide frame 19
It becomes possible to store most of the handrails within the inner periphery of the handrail 2.

In addition, the guide 25 attached to the guide frame 19
Since the lower end 25B closes the gap between the opening of the handrail 2 and the glass panel 18, when a passenger grasps the handrail 2, his or her fingers will not be caught in the gap.

Next, assembling the railing of the passenger conveyor configured as described above is carried out by assembling the upper end of the glass panel 18 that is erected relative to the main body frame (not shown), as shown in FIGS. 5 and 6. Then, as shown in FIG. 7, the fitting groove 23 of the guide frame 19 is fitted to the upper end of the glass panel 18 via the packing 24. After that, the guide 25 is inserted into the two engagement grooves G of the guide frame 19.
The upper end 25A is engaged, and the lower end 25B is parallel to the wall 2.
It abuts on the lower ends 21E of 2A and 22B. Then, the fourth
As shown in the figure, the handrail 2 is mounted on the mounted guide 25.

All of the above-mentioned work can be performed by the worker in an upright position, facing downward, so that the work can be carried out without strain.

By the way, when attaching the guide frame 19 to the glass panel 18, it has been explained that the packing 24 is attached to the upper end of the glass panel 18. , may be attached to the glass panel 18.

〔Effect of the invention〕

As explained above, according to the present invention, the guide frame can be easily attached to the transparent panel since it can be done in an upright position facing downward, and the guide frame can be firmly fixed for a long period of time. can.
