ABSTRACT:
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.
