Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a railing for a passenger conveyor, and more particularly to a railing structure that improves the design and ease of assembly of an inner deck made of stainless steel.

Conventionally, aluminum alloys have been used for the balustrade design members of passenger conveyors, but recently, balustrades made of stainless steel plates have become mainstream due to their high-quality design and excellent durability.

A typical configuration of a balustrade using a stainless steel plate is as shown in FIGS. 1 and 2.

That is, fixed bodies such as a handrail frame 3, an inner deck 4, an outer deck 5, and a skirt guard 6 are disposed between the step 1 of the endless rotating body and the handrail 2, which are directly used by passengers.

All of these fixing bodies are formed by subjecting a thin stainless steel plate to a predetermined process, and are usually arranged continuously along the longitudinal direction of the passenger conveyor.

Here, the structure of the inner deck 4 portion will be described in detail. The inner deck 4 is provided so as to be inclined from the balustrade panel 7 to the skirt guard 6.

Most commonly, one end of the balustrade panel 7 is fixed by a fixing member 4a that engages with the tip of a support 8 that supports the balustrade panel 7, and the other end is fixed to another member by screws 9.

In addition, consideration has been given to safety by providing a protruding tip 4b on the step 1 side so that the passenger's foot F does not approach the dangerous gap g (injury occurs if the foot enters this part).

The inner deck 4 having the above structure has the following problems, and it is desired to solve them.

That is, the fixed body 4 disposed on the back side of this inner deck 4
Point a is joined by welding (spot welding, fillet welding, etc.), but this joining point Z is affected by deformation and discoloration due to the heat effect of welding, as well as pulling force B that acts when load A from passengers is applied, etc. deformation will occur.

This deformation is exposed in spots at the part where the fixed body 4a is placed, such as point Q shown in Fig. 1, resulting in a deterioration of the design, and requires work such as repairing with sandpaper at the time of assembly. The reason why this point Q appears is thought to be that the joining point Z is provided directly on the part that becomes the design surface.

In view of this point, the present invention has been made in order to improve the design and assemblability of a design body made of stainless steel plates.

The gist of the present invention is that the step is arranged in an endless manner and rotates, and the handrail is arranged between the steps and the handrail that rotates at approximately the same speed as the steps, and the skirt guard, the handrail panel, and one end thereof are arranged on the side of the skirt guard. In a balustrade consisting of a stainless steel inner deck, etc., which is joined to the balustrade and whose other end is located at the lower end of the balustrade panel and covers the space between the two, a balustrade extending downward to the balustrade panel side of the inner deck, A fixing piece that does not appear on the surface is integrally provided, and a fixing body is provided inside the inner deck to be engaged and fixed to a support body and welded to the fixing piece.

Hereinafter, one embodiment of the present invention will be described based on the drawings.

In FIGS. 3 and 4, the basic structure of the skirt guard 6, balustrade panel 7, support 8, screws 9, etc. is completely the same as the conventional one, but in the present invention, it is fixed to the conventional inner deck 4. The feature is that the inner deck 10 includes an additional piece 10a and a fixed body 10b.

In this case, the fixed body 10b has a base 10c that almost engages with the back surface of the inner deck 10, and a tip 10d that contacts the fixed piece 10a.
, a gap 10e that engages with the support body 8, and an inner deck 1.
It consists of a retaining piece 10g that engages with the protruding end 10f of 0 (corresponding to the conventional protruding end 4b), and the like.

The connection between the inner deck 10 and the fixed body 10b is as follows.
First, the engaging piece 10g is brought into close contact with the back of the tip 10f, and then the tip 10a is welded to the fixed piece 10a.

As shown in the figure, the welding is performed at point Y, and the welding heat at this time reaches the surface portion through the fixed piece 10a.

Therefore, the heat is not directly transmitted to the surface of the inner deck 10 as in the conventional case, and naturally a thermal deformation point (such as point Q in FIG. 1) does not need to appear on the surface.

Further, it can be said that deformation due to the pulling force B explained in FIG. 1 does not occur, and there is no need to repair the deformed portion as in the conventional case.

In this way, the protruding end 10f of the inner deck 10 on the step 1 side
It is clear that the design and ease of assembly are greatly improved by attaching the inner deck 10 to the fixed body 10b supported by the fixed piece 10a on the side of the parapet panel 7.

According to the present invention described above, there is an advantage that a railing for a passenger conveyor with excellent design and the like can be provided.

Note that the shape of the fixed body 10b described above is not limited to the illustrated one, and may be any shape as long as it consists of at least a portion that engages with the support body 8 and a portion that engages with the inner deck 10.

Claims (1)

[Claims] 1 It is arranged between steps that are arranged in an endless manner and rotate and a handrail that rotates at approximately the same speed as the steps, the skirt guard, the handrail panel and one end are joined to the skirt guard side, and the other end is connected to the skirt guard. In a balustrade consisting of a stainless steel inner deck, etc. located at the lower end of the balustrade panel and covering the space between the two, there is a fixed piece on the balustrade panel side of the inner deck that extends downward and does not come out of the surface during assembly. A railing for a passenger conveyor, characterized in that a fixed body is provided inside the inner deck, and is fixedly fixed to a support body and welded to the fixed piece.
