Title:
REVERSING LINKAGE
Document Type and Number:
WIPO Patent Application WO2004011816
Kind Code:
A3
Abstract:
A linkage mechanism comprising a moveable member mounted for movement with respect to a fixed member to which it is connected. The moveable member is provided with first and second elements spaced from each other with one element constituting a moveable element while the other constitutes a datum element. The relative movement between the moveable member and the fixed member is achieved by means which are located and arranged to preferentially utilise the first of the spaced elements as the datum with respect to which the second element is moved. The mechanism further comprises a means for selectively inhibiting movement of the second element which is preferably electrically controlled, whereby to cause the second element to become the datum. The linkage mechanism may be utilised in a door lock.
