Claim 18:
19. A refrigerated cabinet, which is utilized for accommodating and presenting food to be refrigerated, the refrigerated cabinet comprising:
an enclosure defining a merchandise space in an interior thereof, the enclosure further defining an opening configured to provide access to the interior of the enclosure; and
a pane system configured for selectively closing the opening defined by the enclosure in a closed position, wherein the pane system includes:
a plurality of panes that includes a first pane, a second pane, a third pane and a fourth pane, wherein each of the first pane and the second pane is transparent, thermally insulating and disposed for movement between an open position and a closed position, wherein each of the third pane and fourth pane is disposed for movement between an open position and a closed position;
wherein the first pane and the second pane are disposed to lie in a common first plane in the closed position to form a first pair of panes;
wherein the third pane and the fourth pane are disposed to lie in a common second plane in the closed position to form a second pair of panes,
wherein the second plane is disposed parallel to the first plane and displaced apart from the first plane;
a deflection mechanism carried by the enclosure and defining a first side and a second side, which is disposed opposite the first side of the deflection mechanism;
wherein the deflection mechanism includes a first pulling means having a first end connected to the first pane, wherein the first pulling means having a second end spaced apart from the first end and connected to the second pane;
wherein the deflection mechanism is configured so that movement of the first pulling means with respect to the enclosure moves the first pane in a first movement direction while simultaneously moving the second pane in a second movement direction that is opposite the first movement direction;
wherein the deflection mechanism includes a second pulling means having a first end connected to the third pane, wherein the second pulling means having a second end spaced apart from the first end and connected to the fourth pane;
wherein the deflection mechanism is configured so that movement of the second pulling means moves the third pane in the first movement direction while simultaneously moving the fourth pane in the second movement direction;
wherein the deflection mechanism includes a first deflection pulley and a second deflection pulley, wherein the first deflection pulley and second deflection pulley are coupled to one another to rotate about a common axis of rotation and rotate together to form a rotatable unit; and
wherein the first deflection pulley has a first diameter and the second deflection pulley has a second diameter that differs from the first diameter so that movement of the first pair of panes occurs at a different speed than movement of the second pair of panes.
