WHEELCHAIR ACTUATOR Russian patent published in 2024 - IPC A61G5/02 B62M1/16 B62M1/32 B62M6/00 

FIELD: transport machine building.

SUBSTANCE: wheelchair actuator consists of two onboard wheeled chassis equipped with onboard electric drives and manual mechanisms for transfer of muscular forces to wheeled chassis. Each onboard wheeled chassis is made in the form of three pneumatic satellite wheels of low pressure, which are located at the ends of one of three radial arms of the assembly, which are rotated around the central axis by a globoid-like carrier. Manual drive mechanism is made in the form of a double-lever rocker on the axis, which is mounted in the longitudinal plane of the wheelchair. Lever in the upper long part has a handle, the lower short part of the lever is connected through a tie-rod and a sleeve-roller chain enveloping a sprocket on the central axis, and is connected to a return spring fixed by the other end on the post of the self-orienting pneumatic wheel.

EFFECT: broader functional capabilities of wheeled chassis when moving both on loose soils and on solid support surfaces, including stair flights of general use, in wheel-walking mode.
