Refrigerated display cabinet

Claim 2

In a refrigerated display cabinet including a refrigerating chamber to store and display merchandise and a mechanical chamber in which the refrigerating apparatus is located, an access opening into said refrigerating chamber, movable transparent panels for closing said access opening, said mechanical chamber having an opening, a rear plate for closing said opening and having a plurality of holes for the circulation of air from the interior thereof to the atmosphere, blower means for circulating air from said mechanical chamber through said holes, said refrigerating chamber having a front wall and a rear wall, a bottom wall connected between the lower portions of said front and rear walls, an upper wall partly covering said access opening and having a rear plate, and a pair of side walls having rear edges, the improvement comprising said rear plates of said mechanical chamber and of said upper wall being aligned in the same plane with said rear wall, which plane is displaced forwardly from a plane defined by the rear edges of said side walls whereby when the cabinet is positioned against the wall, the rear wall thereof is spaced from such wall, said upper wall having a duct to direct air onto the surface of said transparent panels, said rear plate of said upper wall having a plurality of holes communicating with said duct for the circulation of air from the atmosphere into said duct, said upper wall having an air outlet opening for directing air from said duct onto said transparent panels, and blower means in said duct for circulating air through said duct onto said transparent panels.

Claim 3

The refrigerated display cabinet as claimed in claim 1 wherein said upper wall has a flanged portion extending horizontally therefrom over said air outlet opening for directing air from said outlet opening onto said transparent panels.

Claim 4

In a refrigerated display cabinet including a refrigerating chamber to store and display merchandise and a mechanical chamber in which the refrigerating apparatus is located, an access opening into said refrigerating chamber adapted to be covered by movable transparent panels, said mechanical chamber having an opening to provide for the circulation of air from the interior thereof to the atmosphere, and a rear plate for covering said opening and provided with a plurality of holes, said refrigerating chamber having a front wall and rear wall, a bottom wall connected between the lower portions of said front and rear walls, an upper wall partly covering said access opening and having a rear plate, and a pair of side walls having rear edges, the improvement comprising said rear plate being aligned in the same plane with said rear wall, which plane is displaced forwardly from a plane defined by the rear edges of said side walls whereby when the cabinet is positioned against a wall, the rear wall thereof is spaced from such wall, said upper wall having a duct to direct air from the rear of said cabinet to the surface of said transparent panels, a guide rail mechanism attached at a front edge of said upper wall to movably support said transparent panels and including a rail element having horizontal running surfaces for supporting said transparent panels, and a frame element for mounting a fluorescent lamp carried by said upper wall and disposed below said guide rail mechanism, said frame element having a plurality of holes for transmitting radiant heat of said fluorescent lamp to said guide rail mechanism.

Claim 5

In a refrigerated display cabinet including a refrigerating chamber to store and display merchandise and a mechanical chamber in which the refrigerating apparatus is located, an access opening into said refrigerating chamber adapted to be covered by movable transparent panels, said mechanical chamber having an opening to provide for the circulation of air from the interior thereof to the atmosphere, and a rear plate for covering said opening and provided with a plurality of holes, said refrigerating chamber having a front wall and rear wall, a bottom wall connected between the lower portions of said front and rear walls, an upper wall partly covering said access opening and having a rear plate, and a pair of side walls having rear edges, the improvement comprising said rear plate being aligned in the same plane with said rear wall, which plane is displaced forwardly from a plane defined by the rear edges of said side walls whereby when the cabinet is positioned against a wall, the rear wall thereof is spaced from such wall, said upper wall having a duct to direct air from the rear of said cabinet to the surface of said transparent panels, a guide rail mechanism attached at a front edge of said upper wall to movably support said transparent panels and including a rail element having horizontal running surfaces for supporting said transparent panels, and a frame element for mounting a fluorescent lamp carried by said upper wall and disposed below said guide rail mechanism, said frame element having a plurality of holes for transmitting radiant heat of said fluorescent lamp to said guide rail mechanism.
