Date Jun. 22, 1995A door closer comprises a housing (21) in which a compression spring (23) urges a piston (22) in one direction, an operating spindle (18) in the housing defining an axis (19) about which an arm mechanism (52) connected to the housing is angularly movable to effect movement of the piston in the opposite direction. Connected between said axis (19) and the piston (22) is a linkage mechanism which provides that, in use, maximum torque is exerted on the arm mechanism at the near closed position of the door. The linkage mechanism can have a pivotal connection (27) between links (25, 26) thereof constrained to follow a continuous curve by means of a cam track (30, 31) or an additional link (48).
Device for the rotatable coupling of a closing element, such as a leaf, a door or the like, and of a stationary support structure, such as a frame, as well as assembly and system for the rotatable movement of a closing element comprising such device
