ABSTRACT:
A mechanism for supporting an auxiliary surface for vertical movement relative to a primary surface includes a pair of link elements having opposite ends pivotally connected to auxiliary and primary surface mounting elements or brackets, a first bias for opposing downwardly directed swinging movement of the link elements relative to the primary surface mounting element, a second bias for opposing pivotal downwardly directed movement of the auxiliary surface mounting element relative to the link elements, and a locking mechanism for releasably constraining swinging movement of the link elements and pivotal movement of the auxiliary surface mounting element. The locking mechanism features a roller and an operator arranged to engage with the roller when moved into a locking position to effect clamping together of the link elements and the auxiliary surface supporting element.
