Claim 16:
17. The pop-up articulating prop module of claim 14 wherein the pop-up articulating prop module is a scissor pop-up articulating prop module, the scissor pop-up articulating prop module further comprising:
a scissor linkage, the scissor linkage comprising a plurality of crossed pairs of links connected in series, the links of each crossed pair being pivotally joined at a middle joint along the length of each link of the crossed pair, and each link of the crossed pair having an end pivotally connected to an end of a corresponding link of a successive crossed pair of links by a respective end joint, the middle joints lying on straight line defining an axis of the scissor linkage, the pop-up direction being an axial direction, and the return direction being an axial direction opposite to the pop-up direction;
the scissor linkage being articulable from a home position to a displaced position, in an expansion direction;
the scissor linkage being articulable from the displaced position to the home position, in a contraction direction opposite to the expansion direction;
the body member being connected to the scissor linkage so that such articulation of the scissor linkage in the expansion direction moves the body member linearly in the pop-up direction from a home position of the body member to a displaced position of the body member and so that such articulation of the scissor linkage in the contraction direction moves the body member linearly in the return direction from its displaced position to its home position;
the automation system being operatively connected between the base and the scissor linkage, the automation system being operable to move one of the middle joints relative to the base in the pop-up direction so as to cause the scissor linkage to articulate suddenly from the home position to the displaced position in the expansion direction and to move the middle joint relative to the base in the return direction so as to cause the scissor linkage to articulate more gradually in the contraction direction.
