Claim 0:
1. A scissor pop-up prop module comprising:
a base;
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;
an automation system;
a prop mount;
the base being adapted and configured to be supported on a flat support surface, the scissor pop-up prop module being adapted and configured to be supported by the base on the flat support surface;
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 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 an axial 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 an axial return direction so as to cause the scissor linkage to articulate more gradually in the contraction direction, the return direction being opposite to the pop-up direction;
the prop mount being connected to the scissor linkage so that such articulation of the scissor linkage in the expansion direction moves the prop mount linearly in the pop-up direction from a home position of the prop mount to a displaced position of the prop mount and so that such articulation of the scissor linkage in the contraction direction moves the prop mount linearly in the return direction from its displaced position to its home position;
a guide, the guide being connected to the base, the prop mount having a spine pole, the spine pole comprising a straight elongate section of the prop mount extending in the axial direction, the guide retaining the spine pole so as to guide movement of the spine pole in the pop-up and return directions.
