Description

TECHNICAL FIELD The present invention relates to an escalator suitable for carrying a wheelchair or the like.

[Background of the Invention]

In the present age, which is aimed at improving the welfare environment, it is desired to adopt specially devised transportation means and building structures so that persons with disabilities who use wheelchairs can act relatively freely.

Recently, with the recognition that the escalator is an indispensable means of transportation inside the building, it is expected that an escalator that can be easily used by people with physical disabilities and the elderly with limited mobility will be available.

However, at present, the installation angle and driving speed, which greatly affect the psychology of escalator users, do not cause any inconvenience to healthy people, but the physically handicapped elderly and physically handicapped people lack the agility to get on and off. For this reason, it has been proposed that the escalator cannot be used, and for these people, the installation angle is reduced to increase the sense of stability when riding, or the transportation speed is slowed to facilitate getting on and off. . In addition, for those who have difficulty walking and use a wheelchair, there is a demand for an escalator that gives special consideration so that the person can use the wheelchair while riding.

Moreover, at department stores, it was not possible to ride with shopping carts at ease. This is because wheelchairs and carts have wheels and generally do not ride on treads with steps in a stable manner.

Conventionally, there are some things that are generally called electric roads and there is no step on the tread, but the drawback is that the entire tread tilts like a slide and the wheelchair is not stable, and the entire equipment is long and the space efficiency is poor. There was a drawback.

As one means for solving these drawbacks, Japanese Examined Patent Publication No. 56-41555
It has been proposed that a specific step is provided in a step group of an ordinary escalator as described in No. 1, and the specific step is stopped, and after the wheelchair gets on, the wheelchair is restarted and carried to the nearest floor. An example of using a large step is shown as an example of the specific step.

However, when a large step is arranged, there is a problem that a large step is generated between the step and the adjacent step.

As a means of solving this problem, as a specific step, a plan to put an auxiliary plate on a normal step to make it large, or to store the auxiliary plate in the step and pull out the auxiliary plate artificially when necessary, etc. Is proposed.

However, even this one has a drawback that it requires a manual operation and causes a handicapped person or an attendant to perform troublesome work.

Further, even if the tread is expanded as described above, the footrest of the wheelchair that rides on the tread may interfere with the step adjacent to the upper step, so that the adjacent step does not interfere with the footrest of the wheelchair. There is also a problem that complicated mechanism for tilting and complicated work are required.

[Object of the Invention]

The purpose of the present invention is not to perform troublesome work on the attendant,
An object of the present invention is to provide an escalator capable of automatically expanding the tread surface of a step and preventing interference between the footrest of a wheelchair and an adjacent step.

[Outline of Invention]

To achieve this object, the present invention configures at least one of a plurality of steps connected endlessly with a specific step in which a tread surface can be raised and expanded, and further, in the specific step. A drive device for raising and expanding the tread surface is provided.

Returning to the original position shown in the figure, the operation of the switch 41 by the switch operating piece 42 stops the motor 16. After that, the operation is started to return to the normal operation.

In the above, the case of ascending has been described, but in the case of descending, the tread surface of the specific step 4 may be raised and expanded at the upper entrance and returned to the normal state at the lower exit.

The above is the description of the embodiment of the present invention. According to this embodiment, the rise and expansion of the tread enables the wheelchair to board without the footrest interfering with the adjacent steps. Since the wheelchair can be handled with one step and the tread surface is automatically raised and expanded, the wheelchair user and the passenger cannot be bothered and troubled.

Although the cross link mechanism is used to raise the tread plate 11 in this embodiment, the tread plate 11 may be raised by another mechanism, or the tread plate 10 may be inverted to turn the tread plate 11. Although it has been expanded, it may be slid backward. Furthermore, it can be used not only for wheelchairs but also for carrying carts, carts, and the like.

〔The invention's effect〕

As described above, according to the present invention, it is possible to automatically prevent interference between the footrest of the wheelchair and the adjacent step due to the expansion of the tread of the step and the rise of the tread without performing troublesome work on the attendant.
