76 a spring 89 is connected between the left side of the actuator 60 and the terminal end of the cable 80 to maintain proper tension in the cable in an alternate embodiment of the invention an electric or pneumatic actuator 60a shown in fig5 a can be used to move the shade 16 between the open and closed positions with the window shade 16 in the fully closed position and having the orientation shown in fig1 and 2 the shade is lowered by moving the actuator to the left as the actuator moves to the left the cable 80 rotates in a counter clockwise direction the lower shade rail 76 being attached to the cable 80 by the locking plate 91 will follow the movement of the cable thus lowering the shade assembly 16 until the lower shade rail 76 contacts the lower inner frame member 24 the cables 88 and 90 shown in fig5 are provided as guides to eliminate vibration and to maintain proper alignment of the shade assembly during ascent and descent the cables 88 and 90 are attached to the upper l shaped support bracket 75 and are routed downward through apertures in the tubes 70 of the collapsible shade and through corresponding apertures in the lower shade rail 76 the cables are then directed over eyelet guides 92 and then downward at 93 to points of attachment 95 with lower frame member 24 as is illustrated in fig5 b and c although the invention modular window insert has been described in connection with the preferred embodiment it.
