Description

Standing wheelchair{wheelchair which can stand up}

The present invention relates to a standing wheelchair, and more particularly, to a standing wheelchair capable of selectively adjusting the height of a seated state of a wheelchair user to conveniently use general residential facilities or convenience facilities that have not been specially modified.

Wheelchairs are commonly used by people with lower body disabilities due to illness or accident, or elderly people whose lower body musculoskeletal has deteriorated due to aging. It is almost impossible for a person sitting in a wheelchair (hereinafter referred to as a'wheelchair user') to use a residential facility or convenience facility that is fitted to the physical condition of a normal person. For example, since sinks and faucets are typically installed at higher positions than wheelchairs, it is impossible for a wheelchair user to use these facilities while sitting in a conventional wheelchair.

European Patent No. 0 815 822, Korean Patent Application Publication No. 2008-0042033, Korean Patent No. 1188899, and No. 00805743 disclose a standing wheelchair. These stand-up wheelchairs are aimed at reducing the risk of lower body movements, bowel function decline, and injuries of wheelchair users due to long sitting in the wheelchair, and to satisfy the feeling of satisfaction to stand up, and wheelchair users use residential facilities or convenience facilities. What makes it easier to do is not considered at all.

On the other hand, as a way to make it easier for wheelchair users to use residential facilities or convenience facilities, there is progress in the direction of renovating residential facilities or convenience facilities themselves so that wheelchair users can easily use these facilities while sitting in a wheelchair.

Not only is this facility renovation expensive, but the use of such a modified exclusive facility gives wheelchair users a sense of separation from ordinary people.
