Abstract

PURPOSE:To reduce the frictional resistance of a skirt guard so as to prevent an accident where a passenger's shoe or the like is caught in between the skirt guard and a step and moreover provide an air-conditioning function. CONSTITUTION:Plural small holes 11 are bored in a skirt guard 10, and a duct 12 is disposed on the rear side of the skirt guard 10 so as to jet cold or hot compressed air onto the step 5 side from the duct 12 through the small holes 11.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a passenger conveyor such as an escalator and a moving walkway, and more particularly to an improvement of a skirt guard of the passenger conveyor.

[0002]

2. Description of the Related Art Conventional skirt guards for passenger conveyors are disclosed in Japanese Utility Model Publication No. 57-191776 and Japanese Utility Model Publication 63-1.
As shown in Japanese Unexamined Patent Publication No. 13079 and Japanese Utility Model Laid-Open No. 1-58586, the top portion is attached to the inner deck, and the surfaces are opposed to each other on the side portion of the step with a gap. Further, the surface is coated with Teflon coating, silicone liquid, etc., to reduce the frictional resistance.

[0003]

In the conventional passenger conveyor configured as described above, since the Teflon coating or the silicone liquid is simply applied, the friction resistance of the skirt guard can be sufficiently reduced. In addition, there is a problem that a passenger's shoes or the like may be caught between the step and the skirt guard, resulting in personal injury.

The present invention has been made to solve the above problems, and an object of the present invention is to obtain a passenger conveyor capable of significantly reducing the frictional resistance of the skirt guard.

[0005]

In the passenger conveyor according to the present invention, the skirt guard is provided with a plurality of small holes for allowing the flow of compressed air ejected from the inside of the main frame toward the steps.

[0006]

In the present invention, compressed air is ejected from the inner side of the main frame through the small holes of the skirt guard to the side of the step, forming an air layer between the skirt guard and the shoes of passengers. Therefore, the frictional resistance can be reduced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to an embodiment shown in FIGS. 1 to 3. In the drawings, reference numeral 1 is a main frame of a passenger conveyor composed of an escalator, and the main frame 1 is shown in FIG. Machine rooms 2, 3 located on the upper and lower floors, respectively
And an inclined portion 4 that is installed so as to be inclined between the machine chambers 2 and 3, and a plurality of circulatingly moving steps 5 are arranged in an endless manner in the inner longitudinal direction thereof. .

Further, as shown in FIG. 3, an outer deck 6 and an inner deck 7 which are adjacent to each other are horizontally mounted on both sides of the main frame 1. A balustrade 8 made of transparent glass or the like is vertically sandwiched between the outer deck 6 and the inner deck 7. An endless moving handrail 9 is wound around the balustrade 8 so as to circulate in synchronization with the step 5.

Reference numeral 10 is a skirt guard whose top is attached to the inner deck 7. The skirt guard 10 is
As shown in FIG. 3, step 5 in which the surface moves circularly
Are arranged opposite to each other with a gap therebetween, and the surface thereof is coated with Teflon coating or silicon liquid. Further, as shown in FIG. 2, the skirt guard 10 is provided with a large number of small holes 11 which allow the compressed air (see the arrow in FIG. 3) to flow therethrough. A duct 12 for compressed air pressure feeding is attached to the back surface of the skirt guard 10. The compressed air is designed to emit cold air in the summer and warm air in the winter.

Next, the operation will be described. Compressed air indicated by an arrow in FIG. 3 is used in the machine room 2 when the passenger conveyor is operating.
Alternatively, after being pressure-fed from the machine room 3 to the duct 12, it is vigorously ejected from the duct 12 to the side of step 5 via the small hole 11. As a result, the shoes on step 5 and the skirt guard
An air layer is formed between 10 and the frictional resistance is sufficiently reduced. Therefore, it is possible to more reliably prevent a personal accident in which the shoes of the passenger are caught between the step and the skirt guard.

Further, since the passenger conveyor in recent years constitutes a part of the internal space of the building, it is desired to have various building functions, such as cooling and heating functions, in addition to the transport function. It was difficult for the conveyor to meet this demand. However, in the above-described embodiment, the cool air is ejected in the summer and the warm compressed air is ejected in the winter in the legs of the passenger, so that the passenger can always feel refreshed. In particular, it becomes possible to greatly increase the service function of the passenger conveyor installed outdoors.

[0012]

As described above, in the passenger conveyor of the present invention, a plurality of small holes are formed in the skirt guard so that the compressed air is ejected toward the steps from the inside of the main frame. The frictional resistance of the guard can be significantly reduced, and it is possible to more reliably prevent a personal injury that passengers' shoes or the like are caught between the step and the skirt guard, and it is possible to improve safety and reliability. And other effects.
