It is well known to transport invalids in wheelchairs or wheeled chairs. However, they have been ineffective for use to transport an invalid to an automobile. In today’s patent, we will discuss Alden B. Davis’ invention, “Invalid transport” (US4010499A), which was patented by the USPTO on 8th March 1977.
The present invention relates to invalid transport which facilitates the entry of an invalid into a vehicle. Due to the defective designs of the prior art inventions, it became impossible to support the invalid in a position extending significantly beyond the door opening of the automobile.
The primary objective of this invention is to provide an invalid carrier having a cantilevered structure supporting the seating area. It also provides a carrier that has a stable wheel configuration. Further, the tilting seating area permits an invalid’s leg to be raised without any head obstruction.
