1. A motorized closure assembly, comprising:
an opening frame configured to fit around an opening;
a substantially rectangular closure slab having a closure slab frame configured to surround the substantially rectangular closure slab and sealingly fit within the opening frame;a driver coupled to a driver pulley, wherein said driver pulley is positioned on a top horizontal side of the opening frame;a frame pulley positioned on an opposite side of the opening frame as the driver pulley;a cable having a proximal end and a distal end, disposed between the frame pulley and the driver pulley, and the cable operably coupled to the slab frame;wherein the rectangular closure slab defines a plane and the driver pulley and frame pulley at least partially intersects the plane; andwherein the driver, the driver pulley and the frame pulley are concealed behind or in the opening frame regardless of a position of the closure slab in relation to the opening frame, and wherein the driver of the motorized closure assembly is capable of slidably moving the slab between an open position and a closed position, and further wherein said assembly comprises multiple slabs serving as an inner pane and an outer pane that each slidably move in a separate parallel channel,wherein each of the inner pane, and outer pane comprise: a closure slab frame, a frame pulley associated therewith, and a secondary frame pulley associated therewith, wherein the cable is looped around the frame pulley and the secondary pulley and wherein an outgoing and returning cable direction are on a same side of each of the inner pane and the outer pane, and further wherein the frame pulley and the secondary pulley include shafts that are offset in relation to a longitudinal axis of a guide rail disposed on the opening frame. |
