An elevationally adjustable folding stage (30) has two stage surface members (32, 34) which form a planar stage surface. The stage surface members (32, 34) fold to substantially vertical storage position. The stage (30) includes elevationally adjustable telescoping legs (80, 82) which can be adjusted to a number of elevations. Height adjustment pins (128) are remotely released from a location that allows lifting of the stage while simultaneously releasing the height adjustment pins (128) for the corresponding stage surface member. Lifting is aided by lift mechanisms (136) to counter the weight of the stage (30). The stage surface members (32, 34) hinge at a center position and are latched and unlatched by a locking mechanism (150). The locking mechanism (150) uses a spring-loaded member (164) with a finger (170) engaging a cam (172) to guide the sections during folding and biasing a rod (174) to a locked position.

An elevationally adjustable stage, comprising: (a) a pair of planar stage surface members; (b) hinge means connecting adjacent edges of the pair of stage surface members for movement between an operative position in which the stage surface members are coplanar to define a common stage surface, and a folded position in which the undersides of the stage surface members face each other; (c) main support legs for each of the stage surface members, and means pivotally connecting the support legs to the respective stage surface member at a position remote from the hinge means; (d) a plurality of cross connect links and means pivotally connecting the links to the support legs and to the underside of the opposite stage surface member; (e) elevationally adjustable lower support legs telescopically positioned within the main support legs; (f) brace means connected to the lower support legs and to the cross connect links for stabilizing the support legs with respect to the opposite stage surface member; (g) means for adjusting the point of connection o the brace means to the lower support legs in accordance with different elevationally adjusted positions of the lower support legs; (h) lifting means connected to the stage surface members and said main support legs providing lift during elevational adjusting and folding of the stage surface members; (i) locking means for locking the position of the lower support legs relative to the main support legs, whereby upon releasing the locking means, the elevation of the stage surface members may be raised or lowered; and (j) remote locking release means for releasing and actuating the locking means at a location remote from the locking means.
