Abstract
An arrangement (16) for controlling movements of an access member (12) relative to a frame (14), the arrangement (16) comprising abase section (18) for connection to either the access member (12) or the frame (14); a fixation part (20) for connection to the other of the access member (12) and the frame (14); a flexible elongated element (22) configured to be tensioned to thereby force the base section (18) and the fixation part (20) to move towards each other in a relative closing movement (86); and a braking device (82) arranged to brake a speed of the relative closing movement (86).
Claims25
An arrangement for controlling movements of an access member relative to a frame, the arrangement comprising:
- a base section for connection to either the access member or the frame;
- a fixation part for connection to the other of the access member and the frame;
- a flexible elongated element;
- a mechanical closing force device configured to tension the elongated element to thereby force the base section and the fixation part to move towards each other in a relative closing movement;
- a braking device arranged to brake a speed of the relative closing movement;
- and
- an electromagnetic generator having a stator and a rotor;
- wherein the elongated element is arranged to drive the rotor relative to the stator by relative movement between the base section and the fixation part to thereby generate electric energy;
- and
- wherein the braking device is arranged to be electrically powered by the generator.
A method of controlling movements of an access member relative to a frame, the method comprising:
- providing a base section connected to either the access member or the frame;
- providing a fixation part connected to the other of the access member and the frame;
- providing an electromagnetic generator, the generator comprising a stator and a rotor;
- driving the rotor relative to the stator by means of a flexible elongated element, and by relative movement between the base section and the fixation part, to thereby generate electric energy;
- tensioning the elongated element by a mechanical closing force device to thereby force the base section and the fixation part to move towards each other in a relative closing movement;
- and
- braking a speed of the relative closing movement by means of electric energy generated by the generator.
