Patent ID: 8383973

Claim:
A tripping assembly for a switching device, the tripping assembly having a trip state and a tensioned state and, in a tensioning event, the tripping assembly is configured to transfer from the trip state to the tensioned state and, in a tripping event, the tripping assembly is configured to transfer from the tensioned state to the trip state, wherein the tripping assembly is configured to be functionally connected to contacts of the switching device such that the tripping event of the tripping assembly is able to change the state of the contacts of the switching device from a closed position to an open position, wherein the tripping assembly comprises: a body part; a tripping axle configured to turn between a trip position and a tensioned position in relation to the body part; a tripping frame configured to turn between a trip position and a tensioned position in relation to the body part, the tripping frame having a turning axis substantially parallel to a turning axis of the tripping axle; at least one tripping spring which has a non-tensioned state and a tensioned state, the at least one tripping spring being functionally connected to the tripping axle and to the tripping frame such that when the at least one tripping spring transfers from the tensioned state to the non-tensioned state, the tripping axle turns in relation to the tripping frame; a frame spring which has a non-tensioned state and a tensioned state, the frame spring being functionally connected between the body part and the tripping frame; and a connecting member configured to functionally connect the tripping axle and the tripping frame both in the final stage of a tensioning event and in the initial stage of a tripping event, wherein, in the tripping event: both the frame spring and the at least one tripping spring are configured to transfer from their tensioned state to their non-tensioned state, to release energy needed for the tripping event to the tripping assembly; and the tripping frame and the tripping axle are configured to turn from their tensioned positions to their trip positions, and while doing so, to turn to opposite directions with respect to one another.
