摘要： Apparatus and associated methods relate to a removable power assist for converting a manual wheelchair into an electronic wheelchair, based on configuring a friction roller to releasably engage with a wheelchair wheel, configuring the friction roller when engaged to drive the wheel through a contact surface with the wheel above the wheel center and behind the wheelchair seating area, configuring a motor to rotate the friction roller, and moving the wheelchair based on engaging the friction roller and activating the motor to turn the wheel through force by the friction roller against the contact surface with the wheel. The power assist may include a user-operable lever configured to engage or disengage the friction roller without a user leaving their seated position in the wheelchair. Configuring the friction roller above the wheel center and behind the wheelchair seating area may permit collapsible wheelchair folding or unfolding without uninstalling the power assist.

摘要： Apparatus and associated methods relate to a wheelchair power assist device configured to be installed, uninstalled and exchanged using an exchange tab welded to a wheelchair, and when installed to switch a motorized friction roller between engaged and disengaged modes with a wheelchair wheel, based on an engagement actuator configured to move the friction roller relative to the wheelchair. The friction roller may be operably coupled with an engagement member configured to move relative to the wheelchair. The engagement member may be moved by an extendable and retractable actuator shaft coupled with the wheelchair. A manual wheelchair may be converted to a powered wheelchair using a motorized friction roller for each wheelchair wheel while leaving an open space behind the wheelchair seating area, advantageously permitting the power assist devices to remain attached to a foldable wheelchair in either folded or unfolded configurations.

摘要： Apparatus and associated methods relate to a removable power assist for converting a manual wheelchair into an electronic wheelchair, based on configuring a friction roller to releasably engage with a wheelchair wheel, configuring the friction roller when engaged to drive the wheel through a contact surface with the wheel that may be positioned under the wheelchair seating area, or to the side of the wheelchair seating area, or to the underside of an armrest, or in front of a wheelchair wheel, configuring a motor to rotate the friction roller, and moving the wheelchair based on engaging the friction roller and activating the motor to turn the wheel through force by the friction roller against the contact surface with the wheel. Some designs include a lever configured to permit a user seated in the wheelchair to engage or disengage the friction roller. Configuring the friction roller under the wheelchair seating area, or to the side of the wheelchair seating area, or to the underside of an armrest, or in front of a wheelchair wheel may permit wheelchair folding or unfolding without uninstalling the power assist.
