Patient Transport Apparatus Having Caster Assembly Biasing Mechanisms

A patient transport apparatus including a support structure movable between a chair configuration for traversing floor surfaces and a stowed configuration for storage. A seat section is pivotably coupled to the support structure. A caster assembly includes a pin coupled to the support structure and defining a swivel axis, a caster frame arranged to pivot about the swivel axis between a plurality of caster orientations, a wheel coupled to the caster frame and arranged for engagement with the floor in the chair configuration, and biasing mechanism interposed between the caster frame and the pin. The biasing mechanism urges the caster frame toward a stowed aster orientation in response to disengagement between the wheel and floor surfaces occurring as the support structure moves from the chair configuration to the stowed configuration.

WHEELCHAIR FOR IMPROVED MUSCULAR SKELETAL SYSTEM ALIGNMENT

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.

FOLDING SCOOTER
20240051637 · 2024-02-15 ·

A folding scooter, including a handle assembly, a support plate assembly, a seat and a connecting assembly. The seat is detachably provided on the support plate assembly. The connecting assembly is configured to achieve the rotational connection between the handle assembly and the support plate assembly. The connecting assembly includes a connecting plate, a hinge shaft and a fixing plate. In this application, the hinge shaft is located below the support plate assembly, such that when the folding scooter is folded, the rotational axis of the handle assembly is located below the support plate assembly, thereby enabling the handle assembly to closely cling to the support plate assembly.

Patient transport apparatus having caster assembly biasing mechanisms

A patient transport apparatus including a support structure movable between a chair configuration for traversing floor surfaces and a stowed configuration for storage. A seat section is pivotably coupled to the support structure. A caster assembly includes a pin coupled to the support structure and defining a swivel axis, a caster frame arranged to pivot about the swivel axis between a plurality of caster orientations, a wheel coupled to the caster frame and arranged for engagement with the floor in the chair configuration, and a biasing mechanism interposed between the caster frame and the pin. The biasing mechanism urges the caster frame toward a stowed caster orientation in response to disengagement between the wheel and floor surfaces occurring as the support structure moves from the chair configuration to the stowed configuration.

Folding rollator

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.

COLLAPSIBLE WHEELCHAIR

The present application provides a collapsible wheelchair, including a front support frame, a backrest bracket, a rear support frame and a bracket connecting rod, which are hinged with each other to form a first connecting rod mechanism; the seat connecting rod is hinged with the front support frame and a seat bracket respectively; the front support frame, the backrest bracket, the seat bracket and the seat connecting rod form a second connecting rod mechanism; a hinge point of the backrest bracket and the seat bracket is located above a central plane of the seat bracket.
