Title: SYSTEM FOR AUTOMATICALLY CLOSING / OPENING A SLIDING DOOR OR SHUTTER
Abstract:
A system for the automatic closing/opening of an aperture (P), comprising: at least one closing element (D) slidable in a plane between a closing position in which it closes the aperture (P) and a position of opening in which the aperture (P) is open; and at least one linear actuator (1) operatively coupled with the at least one closing element (D) to automatically return it from one of the open and closed positions to the other of the open and closed positions. The linear actuator (1) includes at least one jacket (10) defining an axis (X) and at least one rod (20) reciprocally slidable in relation to the at least one jacket (10). The linear actuator (1) includes a stationary element and a movable element, one of the stationary and movable elements including the at least one jacket (10), the other between the stationary and movable elements including the at least one rod (20). The system further includes at least one guide rail (120) for sliding the movable element of the linear actuator (1) defining a sliding direction (d) substantially parallel to the axis (X).
