The present invention relates to a man conveyor, such as an escalator or an electric road, and more particularly, to a reinforcement device of a man conveyor stairs.

Man conveyors have been widely established as an indispensable service facility in buildings. In particular, recently, as part of the urban transportation network, it has begun to be installed in densely populated areas such as subway stations and three-dimensional elevated stations, and operation in a strict installation environment that is not conventionally required is required.

As a result, compared to the environment in department stores, which have been widely used in the past, new demands are mainly generated in terms of durability, such as resistance to invasion of groundwater and surface hardness that is not damaged by contact with passengers. Therefore, the emergence of a man conveyor that can cope with this is expected.

However, conventional man conveyors are arranged in an endless phase to transport passengers, rotating bodies such as handrails rotating synchronously with the stairs, handrail panels forming handrails, handrail frames, outer decks, and external decks. It consists of stationary bodies, such as a nedec, which are arrange | positioned at the back side of a handrail panel opposingly.

And the handrail part is connected to the handrail frame of the curved part, the handrail frame of the inclination part, etc. which were connected to the semi-circular handrail frame by endless connection, and forms the longitudinal direction of a man conveyor.

The handrail frame and the step of the stepped portion of the conventional handrail portion are all composed of an extruded molding material of aluminum alloy and had a great disadvantage in terms of durability and surface damage.

That is, according to the Japanese Metallurgical Society (published in 1962, corrosion-resistant alloy), it is described as the alkali-resistant data as follows.

(Note: unit is mg / dm ₂ / day, 5% caustic soda solution)

That is, aluminum has a corrosion rate of 25,000 times that of stainless steel or steel.

In the place where the man conveyor is installed, the strong alkali concrete is laid and its effect is inevitable, so the result is very serious and most of the current state is at least corroded.

On the other hand, since the shore hardness of aluminum is weak as 13, there is a drawback that it is easy to be damaged even by the contact of passenger's shoes or the like. As a solution of this, it is possible to consider manufacturing the handrail frame and the scaffolding part from stainless steel having twice the hardness of aluminum and the corrosion resistance of 25,000 times.

However, stainless steel is a material that is difficult to machine and has been recognized as a very formable material in the field of plastic processing and is not widely used at present.

An object of the present invention is to enable the application of stainless steel to the handrail frame and the footrest by forming a shape suitable for molding the handrail frame and the footrest. In particular, all the above problems can be solved by making the scaffolding part moldable with a stainless material.

The above object is to construct the scaffolding part into a corrugated body formed by bending a stainless steel sheet, to arrange a reinforcement on the back surface of the scaffolding part of the corrugated body, and to open the handrail frame to the handrail side made of stainless steel sheet. This is achieved by butt welding a second U-shaped member and a U-shaped first member opening toward the handrail panel.

The man conveyor, as shown in FIG. 1, has a staircase (1) and a staircase (1) having a footrest that is engaged with a comb-tooth (not shown) arranged in a stepless manner for transporting passengers and disposed in a hatch (not shown). It consists of a rotating body, such as the handrail 2, which rotates synchronously with 1), and a stationary body, such as the handrail panel 4, the handrail frame 5, and the outer deck 6, which form the handrail part 3. It is.

As shown in detail in FIG. 2, the handrail frame 5 includes a first member 5a made of a stainless steel sheet having a U-shaped cross section that is opened toward the handrail panel 4 and the handrail side 2. The second member 5b, which is made of a stainless steel sheet having an open cross section U-shape, is joined to each other by welding. By constructing such a handrail frame having a two-split configuration, it is possible to produce a stainless steel sheet. In addition, by welding the first member 5a and the second member 5b against each other, there is an advantage in that the occurrence of the gap can be prevented due to this extra bilateral manufacturing error (particularly, an error during bending of the terminal portion). In addition, a drive roller 7 for guiding the handrail 2 to the end of the handrail panel 4 is accommodated in the opening of the first member 5a with the packing 8 inserted therein. Is received and supported. In addition, the opening of the first member 5a is covered by the cover 9.

As shown in Fig. 3, the staircase 1 is formed by bending a stainless steel sheet to support the scaffold portion 10, the riser 11, these scaffold portions 10, and the riser 11 which are corrugated bodies. It is comprised as the reinforcement board 13 adhesively fixed to the back surface of the main body 12 and the footrest part 10, and the space 17 which this footrest part 10 has in the front-and-rear end of the footrest part 10 (FIG. 4) ), Comb pieces 15 and 16 are installed. The comb pieces 15 and 16 are made of a synthetic resin that displays a danger band such as yellow and can achieve two roles of blocking the space 17 and displaying the danger band. The shaft 14 installed in the main body 12 is provided to support a roller (not shown) for stair guide.

4 is an enlarged view of the footrest portion 10, wherein the footrest portion 10 is formed between the cleats 18 and the space between them. It is comprised as the corrugated body which shape | molded the stainless steel plate so that the groove | channel 19 may be provided. In order to prevent the cleat 18 from crushing when the load is applied, the reinforcing plate 13 is welded to the back plate 10 as shown in FIG. The reinforcing plate 13 is detachably fixed to the main body 12.

The space 17 of the footrest part 10 is blocked by the comb piece 16, as shown to FIG. 6, FIG. 7. The comb piece 16 has the cleat part 16a and the frame part 16b. ) Is fixed to the reinforcing plate 13 by the frame portion 16b. In this example, the structure of blocking the space at the rear end side of the scaffolding part 10 is shown, but the front end side is also blocked by the comb piece 15.

8-10 is a modification which made the reinforcement board and the comb piece into another structure. That is, the reinforcement is to arrange the hat-shaped reinforcement frame 20, one each, one in the center, three in total before and after the footrest portion 10 to play the same role as the reinforcement plate (13).

Since the strength can be increased by the use of such a reinforcing frame 20, the scaffolding portion may be made of a thin steel plate (薄 鋼板), thereby reducing the weight. The reinforcement frame 20 is formed in a hat shape with both horizontal portions 20a and 20a 'and a central protrusion horizontal portion 20b, and the main body 12 is formed by both horizontal portions 20a and 20a'. And the scaffolding portion 10 is welded to each other by the central protrusion horizontal portion 20b.

The comb piece 30 for deformation | transformation is comprised with the cleat part 30a, the frame part 30b, and the fitting protrusion part 30c to the space 17. As shown in FIG. In this way, the fitting projection 30c and the space 17 are fitted so that no gap occurs in the coupling relationship between the footrest portion 10 and the comb piece 30. This comb piece 30 is installed on the horizontal portion 20a 'of the reinforcing frame 20 and is fixed to the horizontal portion 20a' with a bolt 31. This mounting structure is applied to the front end of the footrest part 10.

In the above invention, an example in which the handrail frame is U-shaped is enumerated, but a slightly modified shape, such as It also includes a brother.

According to the present invention, a stainless steel sheet is constructed by forming a scaffold with a bent body and mounting a reinforcing device on the scaffold, and a combination of a U-shaped frame that opens the handrail frame to the handrail side and the handrail panel. Since it is possible to adopt, a man conveyor excellent in opening property can be provided.
