A hinge for wings such as ironing board supports the board off a support (3) on pairs of link (2, 3) which engage (29, 30) to limit angular movement beyond a working disposition. The board (24) may be folded and collapsed into a wall mounted cover (28). The wall mounted unit might be fitted to a height adjustment mechanism (118). The links (2, 3) may be combined with a means (63) increasing the angular extent of the folding action to collapse the folded board (80) into a drawer unit (84). The board may be mounted to a turntable (101) to allow for angular movement. The board (24) may be supported on supports (35) attached to sliding tracks (34) to enable movement to a storage position in a cabinet (32).
