<p>A clamp arrangement for clamping a marginal portion of a board (1) between two opposed substantially flat parallel walls (7a). The mechanism (17) is mounted on the board (1) and is arranged to be capable of expansion in a direction normal to the board (1). The mechanism (17) comprises an elongate spring strip (19) extending in the direction of its length along the marginal portion, and having corrugations transverse to its length. An elongate cam (23) overlies the spring strip, the cam having a plurality of cam surfaces (23a) along its length spaced apart at the same pitch as the spring strip corrugations. Clamping is obtained by sliding the cam (23) relative to the spring strip (19) bringing the cam surfaces (23a) into contact with the corrugations, thus causing expen- sion of the mechanism and subsequent pressure on the two opposed walls (7a) dueto compression of the spring corrugations.</p> |
