RING ROLLER Russian patent published in 2016 - IPC B60B19/00 A63C17/00 

FIELD: entertainment equipment.

SUBSTANCE: invention relates to means of entertainment and can be used as sports equipment for skiing on various, primarily flat surfaces. Engineering solution of present invention consists in that a ring roller, consisting of a rigid ring having on its outer surface a treat, installed on inner surface of carriage provided with a footrest with roller bearings and steering elements for hands, made in form two rigid arcs arranged convex sides outwardly in a plane perpendicular to plane of ring, rigid ring is formed as a trough made by multilayer rolling into a ring of a tubular member having on an outer surface evenly distributed on edge rod holders of pneumatic chambers having an internal diameter comparable with diameter of cross-section of trough folded diagonally and fixed on horizontal curves of holder.

EFFECT: use of inventive engineering solutions enables to simplify and unify technology of making a ring roller without losing quality of treadmills under roller carriage support.
