Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to an improvement in an escalator suitable for transporting a wheelchair used by a handicapped person.

[Technical background of the invention and its problems]

The depth of the steps of the escalators currently in use is usually around 400 m, which is sufficient for general passengers in good physical health to use, but it is difficult for people with disabilities to use wheelchairs. Currently, users are unable to use the facility because it is too small, and they must seek help from a third party.

In addition, as a measure for the above-mentioned wheelchair users to get on and off, as disclosed in (% Publication No. 56-41555),
A plurality of large steps with a depth that allows a wheelchair to be placed are incorporated into the moving steps of a conventional general escalator at arbitrary positions, and the large steps are stopped at the entrance/exit as necessary to provide a wheelchair. A device has been proposed in which the vehicle can be boarded by the vehicle, and by pressing a dedicated start switch, the vehicle can be driven for a certain period of time to a predetermined boarding and alighting position and then stopped again. escalators are used more frequently for general purposes, and for this reason, if large-sized steps are always running alongside normal-sized steps, it can be especially dangerous for general passengers. When riding on the rear end of the shaped step, the height of the Han P rail is exactly the height of one step, approximately 400 mm.
■) It is not only dangerous, but also low.
It is easy to feel confused when going up and down, and there are also drawbacks such as a large turning radius in the underground truss section that reverses the moving steps, and a multi-axis structure.

[Purpose of the invention]

The present invention was made under the above circumstances, and its purpose is to enable the normal slope running of mobile steps during general driving, and to make it possible to move the two steps at the same height when driving using a wheelchair. An object of the present invention is to provide an escalator that can run in parallel.

[Summary of the invention]

In order to achieve the above-mentioned object, the present invention provides a first guide rail that guides and supports endlessly connected moving steps so as to be able to run on an incline; a second guide rail installed in parallel with an interval corresponding to that of the guide rail, and a third guide rail that switches and connects both of these guide rails, and the third guide rail is connected to the movable step. The first and second guide rails are connected to each other at the same time as the first and second guide rails are stopped at a predetermined position in the getting-on/off section, and by switching the steps, the two front and rear moving steps are maintained at the same height and can run in parallel. This is a characteristic feature.

[Embodiments of the invention]

Hereinafter, the present invention will be explained in detail based on an illustrated embodiment.

As shown in Figures 1 and 2, reference numeral 1 in the figures is a movable step that is connected in an endless manner, and each of its front and rear wheels 2, 3 is connected to a truss 4.
The first guide to the normal inclined running state is installed on the left and right inside of the
This first guide rail 5 supports the first guide rail 5.
The guide rail 5 consists of a front wheel guide rail 51 and a rear wheel guide rail 52.

The upper guide rail 51 for the front wheels and the lower guide rail 62 for the rear wheels have an interval corresponding to the height h of the step 1, and both the upper and lower guide rails By supporting both the front and rear wheels 2 and 3 of the steps 1 on the 51 and 52, it is possible to horizontally move the steps 1 adjacent to each other by 2 to 3 steps on the A and B sides of the boarding and alighting rows, and gradually tilt the intermediate steps. Both upper and lower guide rails 51.
52 have the same height to form a step. Reference numeral 6 in the figure denotes a second guide rail that is parallel to the first guide rail 5 with a vertical interval corresponding to the height h of the step 1 between the sloped portions of the first guide rail 5. Both wheels 2゜3
A third guide rail 75- is provided at both ends of the second guide rail 6 on the A and B sides of the second guide rail 6. This third guide rail 7 has a configuration in which the first guide rail 5 and the second guide rail 6 are switched and connected, and as shown in FIGS. 1 from the first guide rail 5 to the second guide rail 6 by operating the operation command switch S0 provided on the entrance A side, the switching operation is performed via the pilot motor 8, pinion 9, and ear 10. K is set so that it can be done.

The escalator according to the present invention described above is normally operated in the state shown in FIG. Once stopped at the position, the third guide rail 7 is driven to connect the first guide rail 5 and the second guide rail 6, and then the two steps 1a before and after switching,
Place the wheelchair on lb and restart.

At this time, the front step 1a runs on the first guide rail 5, but the rear step 1b runs on the second guide rail 6, so that both the front and rear steps 6-1h and 1b run on the third guide rail 5. As shown in the figure and FIG. 4, the wheelchairs can be safely transported by traveling in parallel while maintaining the horizontal state. Moreover, the step 1a.

1b is at the same height as the floor on the exit B side, a detection switch S is installed near the falling sun.

After the wheelchair user gets out of the vehicle, the vehicle starts descending operation again with no load, and the detection switch S1 installed near the lower entrance A side detects that the wheelchair user is in a wheelchair. Return to the state position and stop, and operate the third guide rail 7 to move the first guide rail 5 and the second guide rail 6.
This is done by disconnecting the engine and restoring it to normal operating conditions.

In addition, in the above embodiment, the operation operation of the escalator was explained in the case of upward operation, but it is also possible to perform downward operation in the same way, just by reversing the direction of operation.
Additionally, during the series of operations when switching from regular driving to wheelchair driving, or from wheelchair driving to regular driving, it is possible to further improve safety by incorporating an automatic display or audio device to remind passengers of their safety. becomes possible.

〔Effect of the invention〕

As explained above, according to the present invention, there is no need for large steps as in the past, so it can be used as a conventional general escalator during general operation, and it can be used quickly when switching to wheelchair operation. It has a simple structure and has excellent practical effects.
