Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a lifting device for stairs that carries a wheelchair upstairs or downstairs.

[0002]

[Prior art]

 The following is proposed as a conventional stair climbing device for carrying people with walking disabilities upstairs or downstairs. The elevating device has a rail on one side of the stairs in parallel with the direction of the stairs, and guides the wheels of the electric motor drive built in the traveling platform to this rail. The pedestal can be raised and lowered according to the running motion, and the chair is integrally fixed to this pedestal.

[0003]

[Problems to be solved by the device]

 However, the lifting device having such a configuration has the following problems. Since a large load during use is concentrated on the one rail, there is a problem that the rail and the wheel portion are overloaded and the device is easily broken.

The above-mentioned device is for moving a user on a chair and moving it up and down, not for carrying a wheelchair. Therefore, when wheelchair users use it, it is uneconomical to deploy the wheelchairs downstairs and upstairs respectively.

Further, when a wheelchair user uses it, it is necessary to get off the wheelchair and transfer to the chair of the elevator, and after reaching the floor or downstairs, get off the chair of the elevator and put it on a car chair. There was the inconvenience of having to change trains, which placed a heavy burden on the user who was a handicapped person.

Further, since a chair having a width is attached to the stairs, there is a problem that this chair becomes an obstacle when a person normally goes up and down the stairs.

An object of the present invention is to provide a lifting device for stairs that can solve the above problems.

[Effect of device]

 The present invention has the following excellent effects. In the lifting device according to the present invention, since both sides of the lifting platform are guided by the rails arranged on both sides of the stairs, the load during use is stably supported by the left and right rails. Therefore, unlike the conventional lifting device in which the load is concentrated on one rail, the device is not overloaded and there is less risk of failure.

Since the lifting device according to the present invention lifts and lowers a wheelchair, unlike a conventional lifting device in which a chair is integrally provided, the wheelchair remains as it is, from the lower floor to the upper floor, or vice versa. You can move to. Therefore, as in the conventional lifting device, there is no need to dispose the wheelchairs on the upper floor and the lower floor, and since there is no inconvenience of changing trains, the user who is a walking-impaired person is not burdened.

The elevating device according to the present invention does not elevate the chair as in the above-mentioned conventional device, and therefore the width of the stairs does not become narrow. Therefore, if the elevating table is returned to the downstairs side, Usually, people can go up and down stairs without obstacles. Furthermore, on the inner surface side of the handrails standing upright on both the left and right sides of the stairs, guide cavities that are continuous in the direction of the stairs are provided, and upper and lower rails are provided on the upper and lower surface portions of the guide cavities. When the side plates erected on both the left and right sides of the elevator board are stored in the guide space and the upper and lower parts of the side plate are guided to the upper and lower rails, the rails are incorporated in the handrail part. Because of the condition, the width of the stairs is not narrowed by the rail.
