Abstract:
1. A method of controlling opening and closing movements of a wing member in the form of a door or window, comprising: interposing a mechanical energy storage device between the wing member and a frame member, said energy storage device being operable to move the wing member with discharge of energy, and controlling discharge of energy from the energy storage device as a function of the position of the wing member, said controlling including: providing an electronically controllable control element, sensing movement of the wing member at multiple positions and providing an electrical output signal representing same, receiving said output signal at a regulating device and operating said regulating device to control the control element as a function of said output signal to thereby change the influence of the control element to change the energy discharge from the energy storage device as a function of the movement of the wing member by storing a motion profile that includes movement velocities assigning an optimized rate of motion for each aperture angle position of the wing member, wherein the energy storage device comprises at least one spring acting against a movable piston disposed in a housing, the piston divides the housing into two housing chambers containing damping fluid, said housing chambers being connected by a fluid line accommodating flow of damping fluid between the housing chambers during movement of the piston, the electronically controllable control element includes an electronically controllable valve in the fluid line, and comparing actual motion of the wing member with the stored motion profile in the regulating device to control said valve as a function of the wing member position signals by clocked switching between an open position of the valve and a closed position of the valve in order to continuously adjust a flow mass of the fluid through the valve, or by continuously adjusting a flow diameter of the valve using a high-speed servo motor with closed loop feedback to achieve the assigned optimized rate of motion, and displaying data and/or entering data via the regulating device.
