Description

[Detailed description of the invention] Industrial applications This invention relates to a wheelchair.

Problems to be Solved by the Invention Traditionally, wheelchairs have come in a variety of configurations to suit the user, but there are wheelchairs that can be used indoors on the floor and wheelchairs that can be used outdoors on the street. Generally speaking, wheelchairs and wheelchairs are not used separately, and when using the wheelchair outdoors and then climbing onto the floor indoors, the floor will become dirty unless the mud and dirt that adheres to the wheels of the wheelchair are removed. However, recently there has been a trend to try to eliminate the above-mentioned drawbacks by preparing separate indoor wheelchairs and outdoor wheelchairs. However, for people with physical disabilities who use wheelchairs, in order to transfer from an outdoor wheelchair to an indoor wheelchair, or conversely, from an indoor wheelchair to an outdoor wheelchair, it is necessary to first get off one wheelchair. Changing wheelchairs is extremely painful because one has to ride on another wheelchair, and even if wheelchairs are available for indoor and outdoor use, they are not actually used.
