ABSTRACT:
A table has a table top the height of which can be adjusted between an elevated position and a lower position so that the table can be used, for example, both as a billiards table and as a domestic dining table.
Adjustment of the height of the table top is effected with a mechanism, incorporating a support member which can be moved from a retracted position into an extended position at which it acts to support the elevated table top on a support structure. This movement of the support member is effected on lifting of the table top by engagement of a cam follower with a cam surface. Lifting of the table top beyond the elevated position may act to return the support member to its retracted position via engagement of a further cam follower with a further cam surface.
