The patents of Smith, Wheeler, Hazley, Garside, Pool and Culbreth are probably the most relevant.
In the current market the cages are known for the delivery of frozen foods, however the existing cages have a disadvantage: since the cages are not provided with a reducer of cold room, that requires to cool completely the cage when the space is very not used inside of the cage during the delivery of the frozen foods.
SUMMARY OF THE INVENTION
The present invention refers to a cage in which is mounted a reducer of cold room that can be manually raised and blocked during the loading or unloading of the frozen foods, and that automatically slopes down above the frozen foods when the door is closed for reducing the space preserving the frozen foods either by using the ice bags or dry ice during the delivery of the frozen foods.
The cage includes a plurality of tubular members in which are engaged each insulating panel, a pair of legs is mounted under each tubular member including a member with slide rail for receiving a pallet on which resting the frozen foods, a reinforcing bar is mounted in the center of each insulating panel for solidifying the structure of the cage, and a tubular member in which is engaged an insulating panel, is provided with the hinges for connecting a structure in which is engaged an insulating panel on which is mounted a reinforcing bar for solidifying the structure of the door.

DETAILED DESCRIPTION OF THE INVENTION
Now referring to the drawing, and in particular to FIGS. 1 to 12, a reducer of cold room (B) according to the illustrated mode of realization preferred of the invention is intended to be used for reducing the space preserving the frozen foods either by using the ice bags or dry ice during the delivery of the frozen foods.
Referring mainly to FIGS. 1 to 10, it is shown a cage (A) in which is mounted the reducer (B), and which includes an insulating panel (1) that is engaged inside each tubular member (11)(12)(14)(16), and which the tubular member (14) is provided with a hook that allows the reducer of cold room mounted inside the cage to be manually blocked when the hook is engaged in an opening formed therethrough a tubular member (41) which is connected to each tubular member (37) and to a tubular member (40) for receiving a vapor barrier (42), a rubber foam (43) and a rigid sheet (44). An insulating panel (4) which is engaged inside each tubular member (7)(12) and between each tubular member mounted of each side, which a pair of legs (10) is mounted under the tubular member (7) including a member with slide rail (20), which a weather strip (15) is mounted between the member with slide rail (20) and the tubular member (7), and which a reinforcing bar (17) is mounted in the center of the insulating panel (4) for solidifying the structure of the cage. An insulating panel (3) which is engaged inside each tubular member (16)(25) and between each tubular member mounted of each side, which the tubular member (25) includes an angle iron (13) for receiving a reinforcing sliding bar on ball (21) being engaged to each member with slide rail (20)(26) receiving a pallet on which resting the frozen foods, and when the pallet is withdrawn from the cage, the reinforcing sliding bar on ball (21) allows to solidify the front structure of the cage, and which a reinforcing bar (24) is mounted in the center of the insulating panel (3) for solidifying the structure of the cage. An insulating panel (2) which is engaged inside each tubular member (11)(8) and between each tubular member mounted of each side, which a pair of legs (9) is mounted under the tubular member (8) including a member with slide rail (26), which a weather strip (15) is mounted between the member with slide rail (26) and the tubular member (8), and which a reinforcing bar (17) is mounted in the center of the insulating panel (2) for solidifying the structure of the cage. A tubular member in which is engaged the insulating panel (2), is provided with two hinges for connecting a structure (6) in which is engaged an insulating panel (5), and which a reinforcing bar (19) is mounted in the center of the insulating panel (5) for solidifying the structure (6) of the door being provided with a weather strip (18).
The reducer of cold room (B) being formed with a plurality of accordion members (29)(30)(31), which a first accordion member (30) is connected to a tubular member (11) and to a member with slide rail (23) mounted to the tubular member (11), and which the accordion member (30) is also connected to a tubular member (37) mounted to each tubular member (40)(41) of the framework from the reducer (B) and to a member with slide rail (38) mounted to the tubular member (37).
A second accordion member (31) is connected to a tubular member (12) and to a member with slide rail (22) mounted to the tubular member (12), and which the accordion member (31) is also connected to a tubular member (37) mounted to the tubular members (40)(41) and to a member with slide rail (38) mounted to the tubular member (37).
A third accordion member (29) is mounted to the both accordion members (30)(31) thereby two transverse bars (32)(33) being connected by bolts and nuts as illustrated in FIG. 12.
A caster (39) is mounted to each tubular member (37) and (40) to allow the reducer to automatically slope down in straight line and above the frozen foods when the door is closed, and to be manually raised during the loading or unloading of the frozen foods.
As shown in FIG. 11, the reducer of cold room (B) is mounted inside another structure which is adapted in an existing cage for frozen foods (not shown), which includes two frame members (27)(28) connecting each tubular member (34)(35), and which a member with slide rail (36) is mounted to each frame member (27)(28).
The reducer (B) includes the accordion members (30)(31) which are connected to the tubular fame members (27)(28) and to the members with slide rail (36) mounted to the frame members (27)(28), and which are also connected to the tubular members (37) and to the members with slide rail (38) mounted to the tubular members (37).
The accordion members (30)(31) are mounted to an accordion member (29) by each transverse bar (32)(33) being connected by bolts and nuts.
The tubular members (37) are mounted to the tubular members (40)(41) for receiving a vapor barrier (42), a rubber foam (43) and a rigid sheet (44).
A caster (39) is mounted to each tubular member (37) and (40) to allow the reducer to slope down in straight line and above the frozen foods when the door is closed, and to be manually raised during the loading or unloading of the frozen foods.
Although only a single embodiment of the present invention has been described and illustrated, the present invention is not limited to the features of this embodiment, but includes all variations and modifications within the scope of claims.
