A handle grip specially adapted for installation and use upon the main push handles of a wheelchair. The handle grip is adapted to facilitate the reliable, yet temporary, attachment to the wheelchair push handles of the strap(s) and/or the oxygen tube(s) associated with an oxygen tank or generator source for supplying therapeutic oxygen gas to a patient seated in the wheelchair.

A patient transport apparatus transports a patient over a floor surface. The patient transport apparatus comprises a support structure and support wheels coupled to the support structure. An auxiliary wheel is coupled to the support structure to influence motion of the patient transport apparatus over the floor surface to assist users. An actuator is operatively coupled to the auxiliary wheel and operable to move the auxiliary wheel relative to the support structure from a retracted position to a deployed position. A user interface sensor is operatively connected to the actuator and configured to generate signals responsive to the user touching the user interface. A controller is operatively coupled to the user interface sensor and the actuator to operate the actuator in response to detection of signals.

The present invention relates to a removable electric propulsion system (1) intended to be coupled to a rolling object. Propulsion system (1) comprises a frame (2) provided with at least one wheel (3) driven by an electric machine, and at least one non-driven wheel (4), a handlebar (20) and means (5) for coupling the propulsion system to the rolling object, coupling means (5) comprising means for gripping and lifting at least one wheel of the rolling object. Handlebar (20) comprises a connection with frame (2) and/or driven wheel (3). Furthermore, the connection comprises a means (12) for locking/unlocking the handlebar relative to frame (2) and/or to a driven wheel (3) from a locking position where handlebar (20) is attached to frame (2) and/or to driven wheel (3), this locked position of handlebar (20) enabling electric propulsion system (1) to be moved by means of handlebar (20), to an unlocking position enabling at least free motion of handlebar (20) relative to frame (2) and/or driven wheel (3).

Described herein are various improvements to mobility devices. These improvements include, for example, adjustable lateral body supports, multi axial supports for accommodating movement of the pelvis during walking, frame folding assemblies for accommodating storage and transportation, detachable support couplings for supportive accessories, foldaway footplate assemblies for allowing users to rest, wheel brake systems, caster wheel systems, suspension support systems, control button assemblies, and center of gravity adjustment assemblies. One or more these improvements can be combined into various mobility devices as will be described in more detail hereinafter.
