Abstract:
A handle support mechanism for attachment to a lock operable by first and second handles, the handle support mechanism comprising:a first friction element comprising a disc having a friction surface and a first cylindrical bearing surface, the first friction element being connected to and rotationally driven by the first handle when the first handle is turned; a second friction element comprising a disc having a friction surface and a second cylindrical bearing surface, the second friction element being connected to and rotationally driven by the second handle when the second handle is turned; a first non-rotatable friction surface in frictional contact with the friction surface on the first friction element; a second non-rotatable friction surface in frictional contact with the friction surface on the second friction element, the first and second fixed friction surfaces being non-rotatable relative to the lock; and a bracket holding the friction surfaces on the first and second friction elements in frictional contact with the first and second non-rotatable friction surfaces, the bracket including first and second bearing holes engaging the first and second cylindrical bearing surfaces to rotationally hold the first and second friction elements.
