摘要:
A damper assembly (50) adapted to a reciprocative door closer device (10) and contingent door (62), the device (10) comprising a piston rod (16) which functions reciprocatively from within a piston body (12) controlling a biasing means (11); the rod (16) normally loosely mounted with a checking mechanism (22) for variably holding both the rod (16) in an extended position (16-B) and a door (62) in an open position (62-B); the assembly (50) comprising a fixated bracket (50-A) with an offsetting fastener means (52) for universal attachment to left and right hinging doors (62), and, similar to the reciprocative device (10), the assembly (50) comprising an extensible bracket (50-A) controlling a counter biasing means (55) by use of an operator (54) selected from a group including a spring operator means (54-A) that acts to dampen, counter, and protect the device (10) and the door (62) from damage due to excessive inward biasing forces (11-B), and, acts to compensate for a superior checking mechanism (22) such as when the extended rod (16-B) is being held with the engaged mechanism (22-B) and the opened door (62-B) is moved towards the closed position (62-A) without first disengaging the mechanism (22-B), which, simultaneously now commissions the device (10) to return the door (62) to the exact opened position (62-B) determined by the engaged mechanism (22-B) holding the extended rod 16-B.
摘要:
The invention relates to an electromechanical swing leaf operator having a door closer (1) with an eccentrically supported pinion (6) that presents a circular rolling curve and meshes with a toothed rack (5) being disposed at a piston (4), whereby a particular execution of the rolling curve and of the teeth (9) of the toothed rack (5) in adaptation to a toothing of the pinion (6) is achieved. With the intention to realize an optimized moving course of the piston (4) in the housing (2) of the door closer (1) an improved execution of the delayed closing operation is provided.
摘要:
A drive system for a moveable wing, especially for a door or a window, is described. The drive system includes at least one energy storage device by whose discharge of energy the wing is moved. The energy storage device is hereby controllable in its energy discharge by means of a control system. The control system has an electrically controllable control element. The motion of the wing is directly or indirectly detected by a sensor, whose output signal is fed into a regulating device, which controls the control element. The regulating device is realized in a way, that the influence of the control element, dependent on the motion of the wing, can change the energy discharge of the energy storage device.
