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 more particularly to a handrail for a passenger conveyor using a stainless steel plate.

[Conventional technology]

Escalators or electric roadways (hereinafter referred to as escalators) have become widely established as essential service equipment in buildings, but recently, various demands have become noticeable, especially in terms of the design of handrails. As is well known, the handrail makes up the majority of the design of an escalator, and everyone involved is aware that its design is a major selling point as it determines the quality of the interior decoration.

Here, as shown in FIGS. 1 and 2, the escalator's handrails are arranged in an endless manner with rotating steps 1 and moving handrails 2 to carry passengers.
It is composed of almost all stationary bodies except rotating bodies such as the upper deck 3 that supports the movable handrail 2, the guide 4 that guides the movable handrail 2,
As is already well known, it is constructed by combining design bodies such as the lower deck 5, balustrade panel 6, lamp 7, and lamp cover 8 with auxiliary materials such as bolts 9.

These handrail members are usually divided and joined appropriately along the longitudinal direction of the escalator and arranged in a substantially endless manner.

Among these decorative materials, the material for the upper deck 3 and lower deck 5, which constitute the main structure, has long been an extruded aluminum alloy material subjected to an alumite treatment. To explain the advantages of this aluminum alloy using the main deck 3 shown in FIG. 2 as a representative example, there is a space A through which the bolts 9 pass, a groove B into which the parapet panel 6 is inserted, and a space C in which the lamp 7 is housed.
protruding pieces D and E that support the recesses and lamp cover 8.
It has the advantage of being able to form recesses almost freely.

On the other hand, it is known that its disadvantages include a marked tendency for costs to rise due to lack of raw materials, and problems in terms of corrosion resistance and surface hardness. This poor corrosion resistance is serious in subway stations and outdoor exposed escalators, and there are known examples of escalators that cannot withstand long-term use. Further, the disadvantage of being a soft material is that its surface is significantly damaged by external force and contact force from passengers riding on Step 1, making it unable to maintain its function as a design object for a long time.

As mentioned above, although aluminum alloy balustrades are highly praised for their good formability, these drawbacks are extremely disadvantageous for escalators, so recently balustrades made of stainless steel have been rapidly gaining popularity. It is starting to become popular. To explain the structure of Fig. 3 as a typical example of a stainless steel balustrade, the stainless steel upper deck 10 (corresponding to the conventional upper deck 3) is made by bending a thin plate with a thickness of about 1 mm to 3 mm. corner F and G
It is normal to have a structure with a large number of bent parts such as
and F are difficult to mold. Therefore, it is necessary to add members such as the support pieces 11 and 12 for supporting the balustrade panel 6 and the lamp cover 8.

[Problem that the invention seeks to solve]

According to the stainless steel balustrade, the support piece 11
The appearance of a welded deformed part Z for joining the parts 12 and 12, and furthermore, the disadvantage of high cost becomes apparent. This is associated with a decline in design quality and economic problems, and the reality is that this has the disadvantage of hindering the widespread use of highly durable stainless steel balustrades.

Furthermore, the following problems cannot be overlooked with stainless steel balustrades that use thin plates. In other words, since the upper deck 10 is made of a thin stainless steel plate, it is difficult to connect it to the handrail panel 6, and the movable handrail 2 cannot be stably supported unless a special fixing device is provided inside the upper deck 10. There was a problem that I couldn't provide guidance on.

In view of the above points, it is an object of the present invention to solve the drawbacks in terms of design and economy of handrails using stainless steel plates, and to provide a mechanically stable handrail for passenger conveyors. be.

[Means for solving problems]

In order to achieve the above purpose, a support is provided inside the upper deck, this support is joined to the upper part of the upper deck within the width dimension of the moving handrail, and the support is fixed to the edge of the balustrade panel. I decided to do so.

[Effect]

By arranging the above-mentioned supports, the mechanical strength of the upper deck is improved, and since the traces of the joints of the supports are not visible from the outside, there is no deterioration in design, and furthermore, the upper deck can be easily fixed to the handrail panel. The sliding rail provides stable guidance and support.

〔Example〕

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

Balustrade panel 6, lamp 7 and lamp cover 8
The structure is exactly the same as that shown in FIG.
It is distinctive in that it is composed of two parts. The upper deck 13 has a downward opening substantially similar to the conventional upper deck 10 made of stainless steel plate, but the support piece 14 disposed inside the upper deck 13 has an engaging portion that supports the end of the balustrade panel 6. 14a, a support portion 14b that supports the lamp cover 8, and an upper deck 13.
A major feature is that the support body 14 is formed from a fastening portion 14c extending to the top of the support body 14, and is also greatly different from the conventional one in that the support body 14 is made of an elongated aluminum alloy body. In this case, the fastening portion 14c of the support body 14 is always in contact with the upper deck 13 at the upper portion 13a, thereby preventing assembly errors. Then, the upper deck 13 and the support body 14
As shown in the figure, the upper part of the guide 4 is firmly connected to the guide 4 by a bolt 15. The connection by the bolts 15 is within the width of the opening of the moving handrail 2. On the other hand, the upper edge of the balustrade panel 6 is connected to the support 1 through the packing P.
It is inserted and fixed into the engaging portion 14a of No. 4.

By doing this, the upper deck 13 and the support body 14 are joined at their respective upper portions, and the joints are in a position covered by the moving handrail 2.
Since the bonded portion of the support body 14 does not appear on the surface as in the conventional case, deterioration in design quality can also be prevented. Moreover, since the support pieces 11 and 12 that correspond to the conventional support pieces 11 and 12 can be integrated, economical effects can also be achieved. Furthermore, since the support body 14 is fixed to the edge of the balustrade panel 6 without relying on the upper deck 13, the fixation to the balustrade panel is strong, and the guide and support of the sliding rail 2 is stabilized. be able to.

Furthermore, the present invention may be configured as shown in FIG. That is, the upper deck 13 is divided into a main deck 13A with an inverted U-shaped cross section and a sub-deck 13B with a U-shaped cross section, and the lighting device (lamp 7 and lamp cover) is supported inside the main deck 13A, and the balustrade panel 6 is A support body 14 having a fixed portion 14F is disposed, and the guide 4, sub-deck 13B, and main deck 13 are connected within a range corresponding to the opening width dimension of the moving handrail 2.
A. The support body 14 is tightened all at once with bolts 15.

〔Effect of the invention〕

As explained above, according to the present invention, a handrail can be manufactured using a thin stainless steel plate without impairing the design, and therefore an economical and mechanically stable handrail for a passenger conveyor can be obtained.
