20150029033 | Electronic hinged safety switch - An electronic hinged safety switch adapted for installation on protection barriers (B) of machines and/or automatic plants having one or more electric safety circuits (S). The switch comprises a substantially box-like fixed member ( | 01-29-2015 |
20150022027 | Multiple signaling hinged safety switch for mobile protection barriers - A multi-signaling hinged safety switch for mobile protection barriers includes a fixed member designed to be secured to a stationary part of the barrier and having a pair of axial end holes, a movable member designed to be secured to a pivotal part of the barrier and having a pair of substantially transverse arms located outside the fixed member and pivoted to the axial end holes, an electrical detection system within the fixed member switching one or more electric safety circuits of the barrier at a predetermined switching angle. A pair of cylindrical pins extend in cantilever fashion from the arms and are pivotally inserted in the holes, with mutually spaced opposed ends defining a gap with no axial connection member therein. The detection system includes a pair of detectors each interacting with one end of a pin and having a switching angle that are operatively independent of each other. | 01-22-2015 |
20140300412 | Electronic safety device for a protection barrier - An electronic safety device for a protection barrier includes a transponder, a transceiver device for receiving a return signal from the transponder, the transponder being movable with respect to the transceiver and adapted to be placed at a current distance, an electric circuit which is switched when the distance is lower or higher than a reference distance and a control and switching system. The transceiver device processes the return signal to generate a control signal with an electric parameter variable in function of the distance. The control signal is a periodic signal with a frequency and has a first spectrum with a middle interval and a second spectrum with lateral intervals shifted with respect the middle interval when the distance is higher than the reference distance, the parameter being associated to a frequency value that comprises either into the middle interval or into one of the lateral intervals. | 10-09-2014 |
