Description

[Detailed Description of the Invention] [Field of Application of the Invention] This invention relates to a handrail for a passenger conveyor such as an escalator or a moving walkway, and particularly relates to a handrail for a passenger conveyor with an improved supporting part of a moving handrail.

[Background of the idea]

Conventionally, passenger conveyors, such as escalators and moving walkways, are generally equipped with a parapet with a moving handrail on the outside, which necessarily runs at the same speed as the driving speed. In particular, these days many balustrades are designed to have lightness by using materials such as tempered glass for the side walls.

Fig. 1 shows the overall structure of an escalator as an example, where 1 is a handrail, 14 is a step board arranged endlessly inside the handrail 1, and 2 is a moving handrail. 2 runs at the same speed as the tread 14 on the upper edge surface of the handrail 1 within the area used by passengers.

FIG. 2 shows a detailed cross-sectional structure of FIG. 1, in which the moving handrail 2 runs on the inside thereof while being slidably supported by a running track formed by a guide body 3. This guide body 3 is fixed to a frame 4 disposed on the upper edge of the balustrade, that is, the upper end of the panel 8, with screws 5, for example. This frame 4 holds the upper end of the panel 8 with a fixing fitting 6. Further, the upper end of the panel 8 is clamped and fixed via a protective cover 9 made of a flexible material such as rubber to prevent damage due to the clamping pressure of the fixing fittings 6. Further, the lower part of the panel 8 is fixed to a fixing frame 13 provided on the escalator body, and a protective cover 12 or the like is used also in this part to protect the end.

In this structure, many ideas have been made regarding the method of fixing the frame 4 and the fixing metal fittings 6, as well as the structure of the means for tightening the panel 8 by the frame 4 and the fixing metal fittings 6. The structure of No. 6 is complex and requires relatively high precision, and conventionally requires a bent product made of molded aluminum or copper material. In addition, although the structure requires lightness, the frame 4 has to be enlarged in order to store the fixture 6 with good design, and the opaque part H at the upper end of the parapet has to be enlarged. It was hot. Further frame 4
Since the guide body 3 is made of abrasion-resistant material to guide the movement of the moving rail 2, it is necessary to use a separate product separated from the frame 4, and it is difficult to fix it. It required a lot of effort.

[Purpose of invention]

The present invention addresses the above points, and its purpose is to provide a handrail for a passenger conveyor that is simple in structure and has minimal opacity.

[Summary of the idea]

In order to achieve the above object, the present invention includes a guide body disposed inside the movable handrail and within the height of the movable handrail, and a pair of guide bodies arranged downwardly within the height of the movable handrail on the guide body. A vertical wall is extended to provide a groove into which the upper end of the glass panel is inserted, and a pin is passed through the glass panel through an elastic bushing at a position where the upper end of the glass panel is inserted, and this passed pin is inserted into the pair of holes. It engaged with the vertical wall of the

[Example of the invention]

An embodiment of the present invention will be described below with reference to FIG. It should be noted that the lower support structure of the glass panel 8 is the same as the conventional one, so a repeated explanation will be omitted. The guide body 15 according to the present embodiment is disposed inside the movable handrail 2 and within the height of the movable handrail 2, and includes the guide body, frame, fixing metal fittings, and the like, which were conventionally separate parts. The protective cover is integrated and directly fixed to the upper end of the glass panel 8. In order to integrate each conventional component and fix it to the upper end of the glass panel, it is constructed as follows. That is, the guide body 15 is integrally made of a synthetic resin such as nylon having wear resistance and appropriate elasticity in order to slide in contact with the inner circumferential surface of the movable handrail 2 and guide the movement of the movable handrail 2. is formed into. This guide body includes a moving rail guide portion 15G that supports the moving rail 2 and restricts movement of the moving rail 2 in the width direction, and a pair of vertical walls 15A and 15B extending downward from the guide portion 15G. The movable handrail 2 has a groove 15a that opens downward and has a total height within the height h of the movable handrail 2. Further, the groove 15a
The pair of vertical walls 15A and 15B are arranged so that the width of the groove is commensurate with the thickness of the panel 8 because the upper end of the panel 8 is inserted into the upper end of the panel 8 and engaged.
Determine the spacing between.

On the other hand, a through hole 8a is provided in a portion of the glass panel 8 that is fitted into the groove 15a.
An elastic bushing 17 made of rubber or the like is fitted into a.

The groove 15a of the guide body 15 is fitted into the upper end of the glass panel 8 constructed as described above, and the pair of vertical walls 15A, 15B and the elastic bush 1 are fitted.
A pin 16 is provided passing through 7. This pin 16 has both ends connected to the holes 15 in the vertical walls 15A and 15B.
It has a length that protrudes from the surface of the glass panel 8 so as to engage with R. Glass panel 8 like this
By connecting the glass panel 8 and the guide body 15, the glass panel 8 and the guide body 15 are strongly connected.
The guide body 15 can sufficiently withstand the force of lifting the handrail 2 by a passenger. Moreover, in the past, many parts such as fixing fittings, frames, and guide bodies were required, which was troublesome to assemble, but these can be completely eliminated by the guide body 15, and the assembly is also easy. The opaque area created by the traditional frame at the top edge of the frame is no longer present, so
The opaque part is only the height h of the moving handrail 2,
The transparent area can be maximized, making it simple and refreshing. That is, the guide body 1 is moved toward the upper end of the glass panel.
If the guide body 15 is simply fitted into the groove 15a of No. 5, it will easily come off when an upward force is applied to the guide body 15. Therefore, it is also possible to press fit the panel into the groove 15a and communicate using the frictional force. However, when press-fitting into the groove 15a, it is necessary to ensure that both vertical walls 15A and 15B can sufficiently withstand the reaction force of the press-fitting. It is necessary to make the slide guide portion 15G thicker. However, if the moving handrail guide section is made thicker, the two vertical walls 15A, 15B, or in other words, the groove 15a, will protrude to the inside and outside of the moving handrail 2.
As a result, the opacity of the parapet increases. In addition to fitting the groove of the guide into the upper end of the glass panel as in the embodiment of the present invention, the guide is also connected to the vertical wall with a pin 16 that spans the glass panel. It does not easily come off, especially the moving handrail guide part 15G of the guide body.
Since it does not need to be made thick, it can be sufficiently accommodated within the movable handrail 2. Further, even if a vertical force is applied to the guide body 15, the pin 16 does not directly hit the glass panel 8, and the elastic bushing 17
There is no damage to the panel.

[Effect of idea]

As explained above, in this invention, the guide body that guides the movable handrail is directly attached to the panel, and the guide body can be housed inside the movable handrail and within the height of the movable handrail, so that the opaque part can be removed. You can get a simple passenger conveyor parapet with minimal structure.
