A support mechanism (16) supports a first object (12) relative to a second object (14), in which the relative positioning is able to be changed in at least two dimensions, and preferably in three dimensions. The support mechanism (16) comprises a first fixing member (20) for fixing to the first object (12) and a second fixing member (22) for fixing to the second object (14). The support mechanism (10 also comprises a first movement mechanism (30,32, 34) which allows movement of a connection point (24) in a first direction relative to the first fixing member (20 and supports the connection point (24) relative to the first fixing member (20). The first direction may be fixed or it may be variable within a first plane. The first plane may be fixed or variable relative to the first fixing member. The support mechanism (16) also comprises a second movement mechanism (40) which allows movement of the second fixing member (22) in a second direction relative to the connection point (24) and supports the second fixing member (22) relative to the connection point (24). The second direction is at an angle to the first direction, preferably orthogonal. The second direction may be fixed or variable within a second plane. The second plane may be fixed or variable relative to the connection point (24). |
