Component for regulating or modifying the effective length of a round steel chain

摘要

A component (1) for regulating or modifying the effective length of a round steel chain (22) has at least one cross recess consisting of a longer recess (12) and a shorter recess (6). The chain can be threaded into the cross recess. The component also has a pin (11) for fixing the component in a particular position in relation to the chain (22). The pin forms a blocking element and has at least one groove (14) which forms the end of the longer recess when the cross recess is free. During normal operation, the groove is forced by a spring (10) into a position in which the pin (11) blocks the cross recess.
