Description
Technical Field
[0001] The invention relates to the technical field of wheelchair storage, in particular to a three-dimensional wheelchair storage. Background Art
[0002] A wheelchair is a chair with wheels for mobility. It is generally used by elderly people or patients with mobility impairments who have difficulty walking. For crowded public places, such as hospitals, airports, train stations, or large supermarkets, managers usually reserve some wheelchairs to serve the public. With the popularity of the sharing economy, shared wheelchairs have also appeared in the public's field of vision after shared bicycles. Figure 1 The figure shows the wheelchair posts for shared wheelchairs and the shared wheelchairs parked on the wheelchair posts. These shared wheelchairs are generally foldable wheelchairs to increase the number of shared wheelchairs that can be parked. Even foldable wheelchairs only take up floor space when parked.
