TELESCOPIC SUPPORT Russian patent published in 1995 - IPC

FIELD: mechanical engineering. SUBSTANCE: telescopic support has movable section constructed as stands 1 and 2. The top ends of the stands are pivotally connected to cross-piece 5 for permitting rotation in vertical plane about fastening axles. The bottom ends are pivotally connected with rolling bodies 10 and 11 of the locking mechanism mounted for permitting movement over guides of the side stands 15 and 16 of the fixed section. A distance member is constructed as carriage 21 having two rotating bodies 19 and 20 and spring-loaded to base 22 of the fixed section by spring 23 for permitting vertical movement over the longitudinal axis of the fixed section.
