Electric wheelchair with an adjustable overhead canopy

摘要

Various embodiments of an electric wheelchair or other type of motorized conveyance having an adjustable canopy are disclosed. The electric wheelchair includes a motorized chair coupled to the adjustable canopy with a support structure that allows an individual to manually adjust the orientation and/or configuration of the adjustable canopy. The support structure includes a tubing arrangement consisting of plurality of smaller-diameter tubes secured to a respective one of a plurality of larger-diameter tubes, which are coupled together by a collar. Each collar defines a channel configured to receive a smaller-diameter tube and a larger-diameter tube in telescopic relation to each other. In addition, each collar defines a middle portion formed between a first side portion and a second side portion that form respective first and second slots with the middle portion. The channel defines a first smaller passage in communication with a second larger passage in which the first smaller passage is configured to receive the smaller-diameter tube and the second larger passage is configured to receive the larger-diameter tube when coupling the two tubes together. In some embodiments, the adjustable canopy includes a solar panel arrangement that generates energy to charge the battery of the motorized chair and may be reoriented or reconfigured when the adjustable canopy is adjusted.
