Safety coupling

Abstract

The present invention comprises a safety mechanism (), which is related to and/or integrally formed with a safety coupling (), wherein the safety coupling, with a related safety mechanism () actuatable toward and into an initial active retaining position or toward and into a final inactive releasing position, is adapted, upon rotary motion, to allow for the transmission of torque between a first, driving coupling member () and a second, driven coupling member () and wherein said actuatable safety mechanism is adapted to be actuatable in a displacement from an initial active position, via a number of intermediate positions, to a final inactive position. The invention provides for the existence of a guided safety mechanism allocated to the safety coupling with means (), adapted, during a final operating cycle of the safety coupling, to allow the safety mechanism to be displaced in a direction toward and into the initial active position, and from there to again allow a limiting relative movement between the first and the second coupling members, during each subsequent operative cycle.
