A bodyweight stabilizing locomotive device includes a frame configured to support locomotive movement and a stabilizing assembly carried by the frame. The stabilizing assembly has a first spring assembly with a first spring constant, a second spring assembly with a second spring constant different from the first spring constant, and a third spring assembly with a third spring constant different from the first and second spring constants. At least one of the first, second, and third spring assemblies includes lockout means which prevent extension of the one of the first, second, and third spring assemblies beyond a maximum extension.

Disclosed are embodiments for a walking assist device. The device may be capable of transformation into a knee scooter configuration and a hands-free crutch configuration for walking or standing while freeing the hands. The device may also include an elastic member for decreasing the load rate of the device.

The inventive concepts disclosed and claimed herein are generally directed to an improved assisted walking device, such as a cane, walker or wheelchair, that includes an integrated oxygen concentrator housed within the assisted walking device. In some embodiments, for example, the improved assisted walking device includes a handle, a control pad, an elongated housing having an interior chamber, an oxygen concentrator, a leg member and a foot member. The oxygen concentrator detachably positioned within the interior chamber of the elongated housing and including an adsorption system configured to generate a flow of oxygen enriched gas, a compressor that includes a motor, a battery, a plurality of sieve beds configured to extract oxygen-enriched gas from ambient air, and a controller in communication with the control pad.

A rollator to aid mobility is described. The rollator comprises an A-frame with two pairs of uprights, each pair of uprights connected by at least one respective hinge to allow each pair of uprights to be folded or pivot front-to-back and a seat disposed between the two pairs of uprights, the seat foldable side-to-side. To fold compactly the rollator comprises an X-shaped cross-linkage comprising four linkage members. A method of manufacturing the rollator is also disclosed. The four linkage members may extend from a respective upright to a central hub underneath the seat. The cross-linkage may fold or pivot at the central hub in both front-to back and side-to-side dimensions when the rollator is folded away.

The invention describes a releasable wheel mount system for a rollator comprising a wheel axel (1) fastened to a frame (2) comprising a groove (3) near an outer end of the wheel axel (1) and a circular sloped gliding surface (25) at the outer end. The system further comprises a release trigger (4) engaging the groove (4) by means a locking shape (5) locking the release trigger (4) and wheel axel (1) to each other, and releasing the release trigger (4) from the wheel axel (1) a releasing shape (6). The system further comprises a housing (7) with a central cylinder (8) with a cavity accommodating the wheel axel (1), an outer (9) and inner (10) rim stopper, and a trigger cavity (11) accommodating the release trigger, thus locking the release trigger (4) and housing (7) to each other and to the wheel axel.
