Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a balustrade for an escalator or an electric road, and particularly to a balustrade structure in which the number of members is reduced.

[Background of the invention]

Recent escalators often use stainless steel sheet molded parts for their parapet members, eliminating the impression that aluminum alloys, which were often used in the past, were cheap.

In a conventional escalator, as shown in Fig. 3, a handrail 3 stands upright between steps 1 arranged in an endless manner and a handrail 2 that operates synchronously. Publication No. 59-13430 or Utility Model Application Publication No. 57-25
The internal structure is disclosed in Japanese Patent No. 878. These known examples are generally as shown in FIG. 4, in which a gripping body 6 is fitted across a cushioning material 5 attached to the upper end of a parapet panel 4, and a main handrail frame 7, a main handrail frame 7, It guides and supports the handrail 2 by fixing the guide frame 8 and guide 9, and is composed of many types of parts.

The role of the gripping body 6 is the fixing groove 6aiCQ drying panel 4.
The upper end and the cushion material 5 covering it are hammered in and fixed, and finally the handrail guide member (guide 9 etc.) is fixed using the handrail panel 4 as the main member. Here, the gripping body 6 is made of a thick member such as an aluminum alloy, and is provided along the entire length of the escalator, which increases the weight and increases the burden on the handrail panel 4.

It had the disadvantage of high cost.

As described above, the disadvantages of the large number of types and weights of balustrade members result in high costs and increased man-hours for assembly work, and improvements are desired.

[Purpose of the invention]

An object of the present invention is to provide an escalator balustrade that reduces the number of types of balustrade members and reduces the assembly work.

[Summary of the invention]

The present invention is the main handrail frame of the parapet.

It is formed from a thin plate of stainless steel, etc., and has an outer part that opens downward to grip the 1m panel, and a groove part that grips the upper end of the balustrade panel, and this outer part and the groove part are integrated. It is characterized by being molded from plate material.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to the drawings.

Figure d shows the cross-sectional shape of the handrail frame of the present invention.
0 is explained in FIG. 4 and is characterized in that the four members of the 9 gripping body 6, the handrail frame 7, the guide frame 8, and the guide 9 are all integrally molded. Reference numeral 10 indicates side pieces 10a and 10b that open downward so as to grip the parapet panel, and a horizontal piece 1.
The groove part 10B formed by the outer part 10A1 consisting of 0c and 10d and the gripping piece ine, the rising piece 10f forming the guide frame part, and the protruding piece 10g forming the guide part are composed of a single roll-formed stainless steel plate. ing. Furthermore, the outer part 1 is easily susceptible to external forces due to passengers leaning on it, etc.
0A, the gripping piece 10e that needs strength to grip the parapet panel 4, /' The projecting piece 10g of the guide part on which the hand rail 2 slides is made of two layers, which is suitable for maintaining strength and preventing wear. It becomes.

By using the handrail frame 10 made of a -flF product made of roll-formed material, for example, four members are reduced to one, which greatly contributes to reducing weight and improving assembly workability.

Note that the rail frame 11 shown in FIG.
This is divided into the main groove part 1A and the 1 door frame part 10B, but even in this case, the groove part 1
1C has the effect of integrating the grip body 6 into the conventional main handle frame 7. In addition, there is a screw hole lid in the gripping piece 11D of this main rail frame part 11A.
It is also possible to apply a structure in which the parapet panel 4 is crimped from the side with the bolts 12.

〔Effect of the invention〕

According to the present invention described above, there is an advantage that the number of parts of the balustrade member is reduced, and an escalator balustrade with reduced assembly work can be provided.
