PROPULSIVE SUPPORT-BALANCER Russian patent published in 2025 - IPC A61G5/02 A61H3/04 

FIELD: medicine.

SUBSTANCE: invention relates to pedestrian hand supports and hand trolleys. Mobile pedestrian support comprises a frame in the form of a frame, two coaxial wheels connected to the body by means of brackets, and a third retractable wheel pivotally connected to the body. On the frame body there is a handle for gripping the user’s hand bent at the elbow to allow the user to rest on the device, transfer the linear movement along the road and the pressing force to the support. Coaxial wheels are pulled back relative to direction of movement towards the user, and there is an empty space between them. Body is moved forward so that the point of application of the force on the support from the hand is located behind the axes of the coaxial wheels to enable the user to balance against overturning when the upper part of the device is inclined towards the user. Retractable wheel is made with possibility of extension forward relative to direction of movement.

EFFECT: increased reliability of movement with support for a person.
