It is an object to improve riding comfort of a wheelchair having a folding mechanism by keeping an operation part of the folding mechanism from contacting a wheelchair user seated. A folding mechanism includes an operation part for use in changing a state of a left-side support arm and a right-side support arm from one of a folded state or an unfolded state to another. The operation part is arranged below an upper end part of a seat frame with a predetermined space therebetween.

Apparatus and associated methods relate to a wheelchair power assist device configured 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 an attachment member removably secured to the wheelchair. The friction roller may be operably coupled with an engagement member configured to move relative to the attachment member. The engagement member may be moved by an extendable and retractable actuator shaft coupled with the attachment member. A manual wheelchair may be converted to a powered wheelchair using a motorized friction roller for each wheelchair wheel. A plurality of power assist devices may be configured to position a respective plurality of friction rollers to leave 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.

A transport chair of this disclosure includes a frame having a pair of fixed sides and hinged sides, the frame moveable between stowed and deployed states. The frame includes wheel receiving means and armrest and push handle assemblies receiving means with quick connect-disconnect clamps or pins. A bar, which is connectable to, and detachable from, each hinge extends between the pair of hinged sides. When connected to the hinged sides, the bar locks the frame in the deployed state and prevents the frame from moving to the stowed state. The chair may be quickly assembled and then dissembled for storage without the need for tools. When dissembled, the transport chair fits within an within an envelope 9 inches deep×14 inches wide×22 inches long.

A wheelchair configured to impart motion on one or more lower extremities of a user to inhibit inelasticity in joints of one or more lower extremities as a result of extended immobility, and to promote a more natural alignment of one or more upper extremities of the user during manipulation of the wheelchair. The wheelchair includes a seat and a backrest, at least two ground-engaging wheels, a hand mechanism assembly including a hand grip on each side of the wheelchair, and a foot mechanism assembly including a footrest on each of the wheelchair. When a force is applied to one of the hand grips, the wheels rotate for locomotion, and the foot mechanism assembly is actuated, causing the foot rest on the opposite side from the hand grip to move in an arced path, and vice versa, thereby imparting contralateral locomotion.

A seat comprising: an attachment bracket; a seat hub rotatably attached to the attachment bracket in a first axis; a first locking mechanism operable to place the seat hub between a first position and a second position; a seat arm swivably attached to the seat hub in a second axis, wherein the second axis is substantially orthogonal to the first axis; a seating pad rotatably attached to the seat arm in a third axis, wherein the seating pad is caused to pivot into a sitting position; a second locking mechanism operable to maintain the seating pad in the sitting position.

A multifunctional mobility device includes a frame that is configurable between a plurality of modes corresponding to at least a power wheelchair mode, a power scooter mode, and a power walker mode, a plurality of motorized wheels mounted to the frame, and handles pivotally coupled to the frame and communicatively coupled to the plurality of motorized wheels. Pivoting the handles operates the plurality of motorized wheels, wherein each handle is independently pivotable to independently drive rotation of a motorized wheel of the plurality of motorized wheels.

A multifunctional mobility device includes a frame that is configurable between a plurality of modes corresponding to at least a power wheelchair mode, a power scooter mode, and a power walker mode, a plurality of motorized wheels mounted to the frame, and handles pivotally coupled to the frame and communicatively coupled to the plurality of motorized wheels. Pivoting the handles operates the plurality of motorized wheels, wherein each handle is independently pivotable to independently drive rotation of a motorized wheel of the plurality of motorized wheels.

A multifunction mobility device includes a frame that includes a seat member, a first wheeled leg ember coupled to a first side of the seat member and a second wheeled leg member coupled to a second side of the seat member. The first wheeled leg member and the second wheeled leg member each includes an upper leg portion pivotally coupled to the seat member at a distal end and defining an upper arm recess, and a lower leg portion pivotally coupled to the upper leg portion, the upper leg portion and the lower leg portion being collapsible into a collapsed transport and storage mode where the upper leg portion is pivoted relative to the lower leg portion such that the lower leg portion nests into the upper arm recess.

Systems and methods for a multi-function mobility device to provide cargo container transport are provided. A multi-function mobility device includes a frame configurable between a plurality of configurations. The frame includes a plurality of individually controllable wheeled leg members configured to traverse uneven terrain. The mobility device is configured to transform the frame into a cargo transport configuration that accepts two stacks of cargo bins locked together. The mobility device is also configured to transform the frame into a rideable configuration that accepts a person.

An apparatus kit and associated methods relate to a wheelchair power assist device kit 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 the exemplary device kit comprising 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.
