Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a railing of a passenger conveyor, and particularly relates to a guide frame having a structure suitable for obtaining sufficient fastening force between the handrail and the panel even if the guide frame directly below the handrail is reduced in size. This relates to a railing for a passenger conveyor that is equipped with.

There have been some remarkable innovations in the design of handrails on passenger conveyors, such as escalators.In particular, in handrails with transparent glass panels, the guide frame directly below the handrail that runs along the upper part of the panel is almost invisible from the outside. There is.

Figure 1 is a conceptual diagram of the running trajectory of the handrail of the passenger conveyor.The handrail 1 runs in a straight line or in a curve on the top of the railing for safe use by passengers, and then turns around at both ends of the passenger conveyor.

It runs inside the lower part of the parapet as shown by the broken line.

Figure 2 is a partial view of the railing of a passenger conveyor to explain the tripping force applied to the guide frame.
, since a considerable amount of tension is always generated, in the concave curved portion of IF#, as shown in Fig. 2, a force P acts on the handrail 1 to try to separate it from the handrail, which causes the inner surface of the handrail 1 to The guide frame 2 that guides the handrail 2 is also subjected to a force that tries to pull it away from the panel 3, and in a straight section, the handrail 1 may be lifted upward by a single passenger, so the guide frame 2 must be able to withstand these forces sufficiently. A guide frame 2 that guides the handrail 1 so that the
It is necessary to firmly fasten it to the panel 3.

FIG. 3 is a sectional view showing a conventional fastening structure between a parapet panel and a guide frame. In FIG. 3, the upper end of the panel 3 is inserted into a space with a relatively large inner dimension formed on the lower surface of the guide frame 2 provided under the handrail 1, and the upper end of the panel 3 is inserted using the push bolt 4. As shown in the figure, the panel 3 is pressed against the outside to obtain a fastening force.

However, as has been the case recently, when the guide frame 2 is reduced in size to create a parapet with an aesthetically superior cross section as shown in FIG. 4, it is necessary to adopt a fastening means with a completely different configuration from that shown in FIG. As shown in FIG. 4, the guide frame 2' is made of an aluminum molded product, and when the groove 5 is in the groove 5 into which the upper end of the panel 3 can be inserted, the groove 5 can be slightly expanded. Attempts have been made to utilize the elasticity of the panel 3 to fasten the panel 3 to the guide frame 2'. However, in this case, the fastening force changes greatly depending on the accuracy of the width of the groove 5 and the thickness of the panel 3, so in order to obtain a large fastening force, accuracy must be ensured, which requires a lot of effort. , many difficulties are expected in realizing this. In addition, due to deformation of the aluminum material over time, the fastening force became insufficient and the panel 3
There is a concern that it may become detached from the guide frame.

The present invention has been made in view of the above, and its purpose is to obtain sufficient fastening force between the guide frame and the panel even if the guide frame directly below the handrail is reduced in size. To provide a handrail for a passenger conveyor which can be used as a handrail and does not impair the guiding performance of the handrail or the design of the handrail.

The present invention is characterized by a guide frame outer shell made of a low-friction material, into which a panel for guiding the running of the above-mentioned guide frame can be inserted, into which a guide frame is provided directly below the guide frame. A plurality of guide frame outer shell holders having grooves provided at arbitrary intervals on the lower surface into which the upper ends of the above-mentioned Nononel can easily fit; and the upper ends of the panels respectively provided between the holders. The structure is different from a fastening body consisting of a pair on both sides, which holds the part from both sides and firmly fixes the nozzle by means of a tightening means, and also holds the holding bodies on both sides from moving. . .

The present invention will be explained in detail below using the embodiments shown in FIGS. 4 and 5.

FIG. 5 is a cross-sectional view showing one embodiment of the handrail of the passenger conveyor of the present invention, and FIG. 6 is an exploded perspective view for explaining details of the guide frame of FIG. 5. 5 and 6, 1 is a guide frame, and 6 is a guide frame, as shown in FIG.
Panels made of low-friction materials, such as nylon or Teflon molded products (transparent glass panels), that guide the movement of
A guide frame outer shell 7 configured to be able to insert panels 3 into the guide frame outer shell 7, and grooves provided on the lower surface of the guide frame outer shell 7 at arbitrary intervals into which the upper ends of the panels 3 can easily enter, and
A plurality of guide frame outer shell holders 9 having flanges 8 on both sides of the lower part and the upper ends of the panels 3 provided between the holders 9 are held from both sides, and the holders 9 on both sides are moved. It consists of a pair of fastening bodies 11 on both sides made of high-rigidity steel and having a protrusion 10 that rests on the boxwood 8 of a holding body 9 that holds it in place. In addition, a pair of fasteners 1
1 clamps the upper end of the panel 3, and tightens the pair of fasteners 11 from both sides using the tightening bolts 12 and nuts 13 to firmly fix the panel 3 so that it does not move and obtain a large fastening force. There is. Therefore, it is possible to prevent the panel 3 from separating from the guide frame 6. In this state, the collar 8 of the holding body 9 is held down and fixed by the protrusion 10 of the fastening body 11.

Alternatively, a long guide frame 6 can be formed by integrating the guide frame outer shell 7, the guide frame outer shell holder 9, and the fastening body 11 which clamps and fixes the panel 3.

According to the above-described embodiment of the present invention, even if the guide frame 6 directly below the handrail 1 is reduced in size, sufficient fastening force can be obtained between the guide frame 6 and the panel 3, and the handrail 1 can run smoothly. Even if the guide frame 6 sometimes becomes detached from the panel 3, it can be sufficiently resisted, and even if the panel 3 undergoes changes over time, the panel 3 is able to maintain the fastening body 11°, that is, It is possible to prevent the device from separating from the guide frame 6. Moreover, the guiding performance and design of the no-trail 1 are not impaired.

As explained above, according to the present invention, it is possible to obtain sufficient fastening force between the guide frame and the panel even if the guide frame directly below the no-trail is reduced, and moreover, even if the guide frame directly below the no-trail is This has the effect of not impairing the guiding performance and the design of the handrail.
