Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] 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 structure for a passenger conveyor using thick stone panels as the handrail panel.

[Background of the invention]

In general, the performance required of a passenger conveyor includes a wide variety of items, such as transport efficiency, maintainability, and safety, as well as a high-quality design that harmonizes with architectural design and economy. Naturally, there is a demand for product technology that incorporates these various characteristics, and their superiority or inferiority is a determining factor in product value.

The conventional passenger conveyor, as shown in Figure 2,
A step 1 arranged in an endless manner to carry passengers, a rotating body such as a handrail 2, a handrail 3, and an entrance/exit 4
All of these components are supported by a main body frame 5, and are ultimately mounted on the floor 6 of a building. The above-mentioned balustrade 3 is known to have a transparent balustrade as shown in Japanese Patent Publication No. 59-13430 and an opaque balustrade to be described later.

Here, the structure of the transparent balustrade shown in FIG. 3 will be described in detail. This balustrade 3 uses a panel 7 made of transparent tempered glass on the inside, and the upper end of this panel 7 is equipped with a packing 8, a grip 9, and a fixing body 10. This gripping body 9 and fixed body 10
are integrated with the fastening force of the fixing bolt 11,
A handrail frame 12 and a guide frame 1 that grip the panel 7 and cover these structures
3 forms a beautiful outer skin, while a guide 14 fixed to a guide frame 13 guides the movement of the handrail 2.

Further, at the lower end of the panel 7, an inner deck 16, an outer deck 17, a skirt guard 18, and an exterior plate 19 are arranged facing each other with a gasket 15 as a boundary, and these structures are maintained in strength by pillars 20. In addition,
A high-class design is important for this balustrade 3, which is called a transparent balustrade, and the key points are the transparency of the panel 7 and the high-quality materials used for the handrail frame 12, inner deck 16, and outer deck 17. . For this reason, the panel 7, which has a beautifully finished interior and exterior surface, and the outer deck 17 made of high-grade stainless steel are arranged to look beautiful to passengers (arrow A) and those around them (arrow B). Every effort has been made to make it stand out.

On the other hand, in a form called an opaque balustrade, a design body corresponding to the handrail frame 12 in FIG. This type is mainly used as ancillary equipment for railway stations and pedestrian bridges.

Recently, there has been an increasing demand for more unique designs for the above-mentioned balustrades 3 that vary in terms of the type of material used, color tone, and shape.

For example, there is a demand for the panel 7 of the parapet 3, the handrail frame 12, etc. to be made of stone such as marble, granite, concrete, or gypsum board to create a sense of solidity. Particularly recently, there has been an increase in the use of stone materials such as marble in luxury buildings to emphasize a solid and natural feel, and to extend the lifespan of outdoor passenger conveyors, which are directly affected by wind and rain.

However, if a stone material such as marble is used for the balustrade 3, 1. If the panel 7 and handrail frame 12 shown in Figure 3 are replaced with marble, they will have to be made of considerably thicker plates due to insufficient strength. The problem is that the load on the main body frame 5 increases. In terms of strength in particular, while the allowable breaking stress of tempered glass is 1500Kg/cm ² , that of marble is only about 1/10, making it difficult to apply to balustrades.

2 In addition, in the case of the glass panel 7, the fourth
As shown in the figure, the plate thickness is uniform (t) and both sides are smooth (7
a and 7b), but in the case of marble, the fifth
As shown in the figure, one surface 7aa is smooth, while the other surface 7bb is generally uneven (plate thickness t ₁ ,
t ₂ ) cannot withstand the design product.

There are other problems.

[Purpose of the invention]

In view of this point, the present invention provides a balustrade for a passenger conveyor in which a stone material such as marble can be used as the balustrade panel.

[Summary of the invention]

In the present invention, the handrail panel is formed of a stone panel, and a plurality of columns supporting the handrail frame are erected on the main body frame, and each of the stone panels is placed below at least the side facing the steps of these columns. A lower support part having a positioning function at the same time as receiving weight was provided, and the lower end part of the stone panel was supported by the lower support part, while the upper end part of the stone panel was supported by the pillar within the handrail frame. It is.

[Embodiments of the invention]

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

In FIG. 1, parts that overlap with those in the previous FIG.
A on the inside of the step 1 side, and a plurality of panels 22B on the outside opposite to this panel 22A.
It is characterized by having a parapet 23 with A plurality of columns 25 are installed between the panels 22A and 22B to connect the main body frame 5 and the handrail frame 24, and a support 25a at the bottom of each column 25 is installed.
and 25b bear the weight of the panels 22A and 22B and at the same time hold their positions, while the support 25C at the upper end of the column 25 holds the positions of the panels 22A and 22B. Furthermore, panel 22
is divided into appropriate lengths in the longitudinal direction of the passenger conveyor, and the joint Z is caulked with a silicone agent or the like. In addition, handrail frame 2
4 is wider than the conventional handrail frame 12, and the panel 22 is placed within this width range.
A, 22B, the pillar 25, and the support body 25C are accommodated and covered. Also, panel 2
2A is a smooth surface as explained in Fig. 5 (Fig. 5).
7aa) in the figure faces the inner step 1 side, and the smooth surface of the panel 22B (7aa in FIG. 5) faces outward on the side opposite to the step 1. and,
The uneven surface (7bb in FIG. 5) faces the support column 25, and this uneven surface is the line of sight A and B explained in FIG.
It has become invisible. Further, the lower end of the panel 22 is covered with an inner deck 16 and an outer deck 17, as in the conventional case, to maintain a beautiful appearance.

By doing this, the stone panel 22
However, its upper and lower ends are covered by the handrail frame 24, the inner deck 16, and the outer deck 17, and the strength of the handrail 23 is maintained by the pillars 25, which not only improves the aesthetic appearance, but also improves the handrail frame 24.
is supported by the pillars 25 so that no load or external force is applied to the stone panel 22, so the thickness of the stone panel 22 can be made thinner and the strength burden on the main body frame can be reduced. Panel 2
By simply placing and fixing the lower end of 2 on the lower end support 25b of the column 25, alignment work with adjacent panels can be easily performed. Can provide balustrade structure.

〔Effect of the invention〕

According to the present invention described above, there is an advantage that even when a stone panel is used as the balustrade panel, a balustrade for a passenger conveyor that is excellent in both beauty and strength can be provided.
