Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a passenger conveyor such as an escalator or an electric road, and particularly to a railing structure that is excellent in design and economy.

[Background of the invention]

A conventional passenger conveyor generally has a structure as shown in FIGS. 1 and 2. That is, moving bodies such as a step 1 and a handrail 2 that are arranged in an endless manner and rotate, a substantially U-shaped handrail frame 3 that guides the handrail 2, a handrail deck 4, a molding 5, etc. A balustrade 8 is provided which is composed of balustrade design materials, a balustrade panel 6 that closes the space between these balustrade design materials and the step 1, an exterior board 7, and the like. Furthermore, inside this parapet 8, there are a support 10 fixed to the main body frame 9 that maintains the full strength of the passenger conveyor, supports 11, 12, and 13 fixed to this support 10, etc. While supporting the handrail frame 3 and handrail deck 4 via screws 14, the molding 5 is supported via screws 15 on the outside thereof,
Furthermore, the support 12 holds the parapet panel 6 and the support 1
3 has a mechanism to support the exterior plate 7.
The handrail deck 4 has a U-shaped part 4a that covers the upper end of the handrail panel 6 on the inside, and a U-shaped part 4b that covers the upper end of the exterior plate 7 together with the molding 5 on the outside. It forms a roughly C-shape.

In such a conventional balustrade configuration, a problem arises in that the design and safety are impaired as shown in FIGS. 3 and 4. In other words, the handrail deck 4 and the molding 5 may be arranged continuously in the entire length direction of the passenger conveyor, but
Since the columns 10 and supports 11 that support these are arranged at intervals of about 1 m as shown by the symbol P in FIG. The gap g significantly reduces the appearance of the handrail 3 and is a safety defect in that it invites the intrusion of passengers' hands and foreign objects.
This phenomenon is caused by the handrail frame 3, which is U-shaped or C-shaped and has strong vertical rigidity.
Compared to the handrail deck 4, the molding 5, which is simply L-shaped and easy to bend downward, is the support post 1.
This occurs because the molding 5 tends to sink in the non-zero portion, and is caused by the molding 5 bowing downward from the straight line Z that should originally be maintained. As a means to prevent this bad phenomenon, the supports 11 are arranged over the entire length of the passenger conveyor, or the supports 10 are planted on the main body frame 9 at even finer intervals, but this increases the weight, This is a big disadvantage in terms of assembly man-hours and manufacturing costs.

[Purpose of the invention]

In view of this point, the present invention has been made in order to provide a passenger conveyor that is excellent in design, safety, and economy.

[Summary of the invention]

The present invention provides effective support between the columns 10 and 10 in order to provide a parapet structure in which no gap g is generated between the handrail deck 4 and the molding 5 without increasing the number of columns 10 and supports 11. The body is arranged. That is, a plurality of pillars fixed at intervals in the longitudinal direction of the main body frame, a first member supported by the pillars and having a substantially U-shaped cross section on both sides, and a first member on the one side of the first member. In the handrail of a passenger conveyor, the railing of a passenger conveyor includes an exterior plate whose upper end approaches a substantially U-shaped cross section, and a second member having an inverted L-shaped cross section located between the exterior plate and the first member. A support body supported by a substantially U-shaped section on one side of the first member and sandwiching this substantially U-shaped section and a horizontal section of the second member with an inverted L-shaped section is provided between the adjacent columns. It is.

[Embodiments of the invention]

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

In FIGS. 5 and 6, the basic structure of rotating bodies such as a step 1 and a handrail 2, a handrail frame 3, a handrail deck 4, a molding 5, a support column 10, etc. is the same as the conventional one, but In the present invention, one of the U-shaped portions 4b having a substantially U-shaped cross section formed on both sides of the handrail deck 4, which is the first member, and a molding, which is the second member, are formed approximately at the center of the pillars 10 and the pillars 10. Deing 5
It is characterized by the provision of a support body 16 that brings the parts into close contact with each other. Here, the support body 16 has a substantially C-shaped cross section, and has an opening 16a that engages with the U-shaped portion 4b of the handrail deck 4 and sandwiches the thickness of the horizontal portion of the molding 5 that has an inverted L-shaped cross section. , fixing bolt 17
It consists of a groove 16b into which the head 17a is attached, and a hole 16c through which the fixing bolt 17 passes.
When the nut 18 is screwed into the fixing bolt 17 and tightened, the gap g between the openings 16a closes, and the horizontal part of the molding 5, which has an inverted L-shaped cross section, is pressed against the highly rigid handrail deck 4. ing. Note that the horizontal portion of the molding 5 is also provided with a hole opposite to the hole 16c, through which the fixing bolt 17 passes. Therefore, the support body 16 is prevented from falling off from the molding 5, and more secure fixation can be achieved.

By doing this, the handrail deck 4 and the molding 5 are in close contact with each other without any gaps even in areas where the support 10 and support 11 are not provided.

Therefore, there is no need for any work such as narrowing the installation interval of the supports 10, which would increase the weight.

〔Effect of the invention〕

According to the present invention described above, there is an advantage that it is possible to provide a railing for a passenger conveyor that has a structure that suppresses an increase in weight and is excellent in design and economical efficiency.

Although the above example describes an opaque type passenger conveyor, substantially the same method can be adopted even in the case of a transparent type.
