Abstract

PURPOSE:To easily expand the width of a scaffold when a large burden is to be carried by providing two types of guide rails for guiding rear wheels which is provided on the moving step of a man conveyer, and by transferring each guide rail of the rear wheel by means of the guide rail for switching. CONSTITUTION:A transfer step plate 2 connected endlessly is provided with front wheels 5 and rear wheels 4, and the wheels 5, 4 are guided and moved along a first guide rail 6 for front wheel and a second guide rail 7 for rear wheel, which are provided right and left in a truss 1, and by which the wheels are guided under a normal tilted running condition. A third guide rail 8 for guiding and supporting the rear wheel 4 is provided between and in parallel to the tilted part of the second guide rail 7, at a vertical interval corresponding to the height of a step. A fourth guide rail 9 for switching and connecting the second and the third guide rails 7, 8 with one another, is provided on the riding port sides on both end parts of the third guide rail 8. They are switched and worked by energizing an electromagnetic coil 10 caused by the operation of a driving command switch provided on the riding port.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a passenger conveyor which is suitable for passengers to carry a large amount of luggage or a large amount of luggage.

[0002]

2. Description of the Related Art The depth of a moving step of a passenger conveyor is
Usually, it is about 400 mm, which is a sufficient depth dimension for use by passengers carrying a small amount of luggage and the like, but it may be narrow and inconvenient for use by passengers carrying a large amount of luggage or a large amount of luggage. Japanese Patent Publication No. 60-183487 discloses that, by switching the guide rails of the moving steps, when the specific user such as a wheelchair is driving, the two front and rear moving steps can be run in parallel at the same height. It was the escalator I did.

[0003]

However, in this escalator, after the operation of a specific user such as a wheelchair, it is necessary to reversely move the moving step stopped at the exit to return the switched guide rail to the original position. was there.

An object of the present invention is to allow a large amount of luggage or a large luggage to be placed on a moving step without having to reversely switch the guide rails for switching.

[0005]

In order to achieve the above object, the present invention provides two types of scaffolds for steps that guide and support the rear wheels of the moving steps, namely, a guide rail that is horizontal and a guide rail that is inclined. A guide rail is provided to switch only a specific moving step to the latter guide rail at the entrance by a switch provided at the entrance. Further, a guide rail for switching the switched moving step to the former guide rail is provided at the exit.

[0006]

By slanting the scaffolding of a specific moving step and combining it with a moving step having a horizontal scaffolding, it becomes easy to carry a lot of luggage or a large luggage. Further, since only the rear wheels are switched by the guide rails, it is possible to return them to the original state at the exit, and there is no need to reverse the vehicle as in the known example.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Referring to FIG.
This will be described with reference to FIGS. 2, 3, 4, and 5.

The moving steps 2 shown in FIGS. 1 and 2 are endlessly connected moving steps, and the front wheels 5, 5 of the moving steps 2 are connected.
The rear wheel 4 is supported by a first guide rail 6 for the front wheel and a second guide rail 7 for the rear wheel, which are provided on the right and left sides inside the truss 1 and guide in a normal inclined traveling state.

The third guide rail 8 is the second guide rail 7.
The guide rails are provided in parallel between the inclined portions in parallel with a vertical interval corresponding to the height h of the step, and guide and support the rear wheel 4 of the moving step 3. Third guide rail 8
Fourth guide rails 9 are provided on the entrance / exit A and entrance B sides at both ends of the. This 4th guide rail 9
5 is a guide rail for switching and connecting the second guide rail 7 and the third guide rail 8, which is operated by the passenger of the operation command switch S ₀ provided with the moving step 2 at the entrance / exit of the electromagnetic coil 10, shown in FIG. The arm 11 is operated and the second
The guide rail 7 is switched to the third guide rail 8 for connection. By this operation, only the specific step among the moving steps 2 becomes the inclined moving step 3. The state of the tilt moving step 3 at this time is as shown in FIG. 5, and the moving steps 2 after the tilt moving step 3 are returned to the normal traveling state by driving the fourth guide rail in FIG. As a result, the rear wheels 4 of the inclined moving step 3 run on the third guide rail 8 shown in FIG. 3, and the other moving steps run on the second guide rail. In the inclined moving step 3 that has run while maintaining such a state, the inclined step detecting switch S ₁ installed at the exit is operated to drive the fourth guide rail 9 in the same manner as in FIG. Then, the rear wheel 4 of the inclined step 3 is moved to the normal operation.

As described above, the passenger conveyor according to the present invention normally performs the operation shown in FIG. 1 and switches to the operation shown in FIG. 2 when the passenger operates the operation command switch S ₀ .

In the embodiment, when switching from the general driving to the driving shown in the present invention, only the inclined moving steps are caused to emit light by the light emitting devices attached to the moving steps for the purpose of promoting safety to passengers, or By incorporating a voice device, etc., it becomes possible to further enhance safety.

[0012]

According to the present invention, by connecting a moving step in which a normal scaffold is a horizontal moving step and an inclined scaffold, the size of the scaffolding of the moving step is expanded, and more luggage and It is possible to carry larger packages and the like.
