<p>An assembly for supporting a body having approximately a predetermined dimension, particularly a printed circuit board (1), comprises frame (4, 11-14), at least one support member (9), and further support means, suitably another support member (10), An edge (5) of the body (1) is received in a groove (7) extending along and into the support member (9). The body (1) and frame (4, 11-14) comprise co-operating locating means such as a plug (2) and socket (31 which locate one end of the body (1). To enable the locating means (2, 3) to be guided into correct engagement without the support member (9) needing to be very accurately positioned relative to the locating means (3) on the frame and then to maintain the support member (9) in firm engagement with the body (l), the support member (9) is rotatable within a restricted range about an axis which is substantially parallel to the groove (7) and spaced from it, the axis itself being movable in the plane of the groove (7),and bias is provided to resiliently urge the support member (9) against the body (1). This may be achieved by providing in the support member (9) a further groove (19) through which a resiliently deformed rod (21) extends so that the support member (9) can rotate about the rod (21), suitably at a small region mid-way therealong. The rotation of the support member (9) is restricted by lugs (25, 26) on the member (9) engaging the sides of a channel (29) in an adjacent frame member (11).</p> |
