The present application relates to a cable tension adjuster for a manually operated, height-adjustable wheeled vehicle. The vehicle includes a brake assembly including a brake cable assembly and a brake cable housing shaped to enclose an excess portion of the brake cable assembly. The brake assembly includes a cable adjuster coupled to the brake cable assembly, where the cable adjuster is enclosed by the brake cable housing. The brake cable housing provides an access port to access the cable tension adjuster.

A patient support apparatus that is adaptable to multiple modes of transport includes a variable length base and a drive system that includes two independently drivable wheels that are responsive to inputs from a user to steer the patient support apparatus.

An anti-pushback mechanism for a wheelchair provides for a side mounted lever to allow the wheelchair to move in a forward motion only, a rearward motion only, or a neutral position where it can be pushed in any direction. This lever is connected to a ratcheting style gear that stops rollback when engaged. A torsion spring moves the chair forward slightly as the user stands to keep the chair close to the user and prevent falling. The invention may be provided as an add-on kit for existing wheelchairs. The kit would consist of a center axle, the ratchet gear, the torsion spring, the crossbar frame, the actuating lever, a guard for the lever, and any associated clamps and fasteners.

An apparatus for moving a wheelchair, the apparatus having a base including a drive motor drivingly connected to a drive wheel and a first forwardly extending lower arm member engageable with the wheelchair when the wheelchair is in the engageable position. The first lower arm member is operable between a lowered position in which the first lower arm member is disengaged from the wheelchair and a raised position in which the first lower arm engages the wheelchair. The first lower arm member has a first stop member whereby, when the first lower arm member is in the raised position and engages the wheelchair, and when the wheelchair is on a forwardly extending declined surface, the first stop member inhibits forward motion of the wheelchair.

An illustrated view of an exemplary walker device for a person necessitating the need of a walker and a wheelchair is presented. The walker device is light weight, foldable, provides contemporary conveniences and is cost efficient. The walker device can be further converted easily into a wheelchair.

A portable wheelchair is collapsible for ease of development, handling and transport, while also providing a front steer configuration and a rear steer configuration.

The present invention provides an assistive mobility device convertible between a rollator mode and a transport chair mode.

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 patient support apparatus that is adaptable to multiple modes of transport includes a variable length base and a drive system that includes two independently drivable wheels that are responsive to inputs from a user to steer the patient support apparatus. A barrier assembly is secured to the upper frame by a tab which is received into a receiver formed in a head end of the frame.

In a power transmission mechanism 20, a line connecting a center shaft 21 of a reference gear member 40 and a first shaft 44 of a first planetary gear member 42 and a line connecting the center shaft 21 of the reference gear member 40 and a second shaft 47 of a second planetary gear member 45 form a specific angle α. Rotation in one direction is prevented when a first carrier member 22 and a second carrier member 32 are relatively rotated in a direction to decrease the specific angle α. Further, a rotation prevention release unit is provided to release a prevention state of the rotation when the first carrier member 22 and the second carrier member 32 are relatively rotated in a direction to increase the specific angle α.
