Claim 11:
12. The scissor pop-up prop module of claim 6, further comprising
the transmission including an extension cylinder and an extension rod;
the extension cylinder being mounted to the base;
the extension rod having a length being slidably connected to the extension cylinder to permit movement of the extension rod in opposed first and second longitudinal directions relative to the extension cylinder, the extension rod having a proximal end disposed in the extension cylinder and a distal end pivotally connected to the scissor linkage at the location of one of the middle joints, such that movement of the extension rod in the first longitudinal direction moves the middle joint in the pop-up direction relative to the base, which in turn causes the scissor linkage to articulate in the expansion direction, and such that movement of the extension rod in the second longitudinal direction moves the middle joint in the return direction relative to the base, which in turn causes the linkage to articulate in the contraction direction.
