REFRIGERATING APPLIANCE Filed Dec. 16, 1954 INVENTOR. DOA/A40 A. LEW/5: JP. BY J Arr-Nays United States The present invention relates to food refrigerating appliances and the like and, more particularly, to a domestic refrigerator and/ or a food freezer appliance.

It is an object of the present invention to provide a refrigerator and/or a food freezer appliance and the like having a new and improved storage cabinet which provides greatly improved accessibility to all parts of its storage space.

Another object of the invention is the provision of a refrigerator and/ or a food freezer appliance and the like having a new and improved storage cabinet of the vertical or upright type in which a vertically extending section of the storage cabinet is made separable or movable and is hinged for horizontal movement to and from its cab inet closing position.

A further object of the invention is the provision of a generally rectangular, box-like storage cabinet of the vertical or upright type in which the front corner sections of the storage cabinet are made separable and are hinged for horizontal movement to provide easy access to all portions of the storage cabinet.

Another object of the invention is the provision of a generally rectangular refrigerator cabinet of the vertical or upright type in which the front corner sections of the cabinet are made separable or movable and are hinged adjacent their front inside corner edges for horizontal movement individually from a cabinet closing position to an open position forwardly of the storage cabinet.

A still further object of the invention is the provision of a refrigerator cabinet made in two or more vertical sections, one of said sections being adapted for stationary support and equipped with refrigeration mechanism, and another of said sections being hinged to said stationary section about a vertical axis and containing a cooling coil flexibly connected to the refrigeration mechanism attached to the stationary section.

Other objects and features of novelty will appear as I proceed with the description of that embodiment of the invention which, for the purposes of the present applica tion, I have illustrated in the accompanying drawing, in which:

Fig. 1 is a perspective view of a household refrigerator embodying the principles of the present invention; and

Fig. 2 is a plan view of the refrigerator shown in Fig. 1 showing the right-hand closure structure of its storage cabinet in its open position and indicating the cooling coils and connecting piping of its refrigeration system more or less schematically for claritys sake.

While the present invention has been shown in the drawing as embodied in a household refrigerator for storing food and other perishable commodities, it will be understood that the present invention is applicable to any type of refrigerating appliance wherein easy access to all parts of the appliance is desirable for the addition or removal of articles therefrom, as is the case in a refrigerator and/ or a food freezer appliance.

In its broader aspects, the present invention contemplates the provision of a storage cabinet for refrigerators,

atent 2,752,761 Patented July 3, 1956 food freezer appliances and the like having one or more sections of its enclosure made separable and hinged so that the separable section or sections of the storage cabinet may be swung to an open position wherein easy access is obtained to the separable sections and to the adjacent portions of the remainder of the storage cabinet. The storage cabinet may be of any suitable shape, as for example, cylindrical or a generally rectangular, box-like shape, and the separable sections may extend for only a portion of the height of the storage cabinet or they may extend for the full height of the storage cabinet, depending upon the particular application. The above-described separable sections may be spaced apart from one another by stationary portions of the cabinet, or they may comprise adjoining sections of the cabinet, which latter arrangement will be seen to have particular advantages from the following description of the preferred embodiment of the invention.

The storage cabinet A of the refrigerator shown in the drawing comprises a rectangularly shaped, box-like structure 10 having two

separable corner sections

11 and 12 hinged about vertical axes for horizontal movement to open positions permitting access to the separable sections and t0 the remaining portion of the storage cabinet. The separable corner sections of the

cabinet

11 and 12 respectively may be of any desired height, width and depth provided each section contains a suitable fraction of the total volume of the cabinet and may be hinged to the stationary portion 13 of the cabinet in any convenient manner. The cabinet, as viewed in Fig. 2, will have particular advantages, however, where the separable corner sections each have a width approximately equal to one-half of the front side of the cabinet and together form the front section of the cabinet, and Where the separable sections are hinged along a common vertical axis positioned between the separable sections adjacent the front surface of the cabinet as shown in the drawing. In the preferred and illustrated embodiment the storage cabinet thus comprises a generally rectangular, box-like stationary section 13 open on its forward face 14 and two rectangularly shaped, box-like separable or

movable sections

11 and 12 each having a height equal to the height of the stationary section 13 and a width approximately equal to one-half of the width of its open face with the

separable sections

11 and 12 being hinged about a common vertical axis 9 positioned forwardly of the midpoint of the open face 14 of the stationary section a distance approximately equal to the depth of the movable sections to form the closure members of the cabinet. Stated in slightly different language, the storage cabinet A shown comprises a generally rectangularly shaped, box-like structure having its two front quarter sections made movable and hinged about a common vertical axis positioned adjacent the midpoint of the front surface of the cabinet.

The separable or

movable sections

11 and 12 of the storage cabinet may be made to seal the cabinet when in their closed position in any suitable manner. As shown in the drawing, the forward face 14 of the stationary section 13 is made relatively smooth to provide a proper sealing surface and is provided with relatively narrow, forwardly projecting members 15 and 16 on its top and bottom surfaces 17 and 18 respectively, which in effect extend the sealing surfaces of the stationary section 13 forwardly between the closed positions of the movable members. A vertical post 20 is positioned between the forward ends of the forwardly projecting members 15 and 16 immediately behind the hinge structure 21 to provide a separate, continuous stationary sealing surface for each movable section to seal against. A continuous rubber strip 22 is provided along cooperating surfaces on the movable members such that a seal is effected when the movable members are in their closed positions. Alternatively, the forwardly projecting members 15 and 16 can be omitted and the

movable sections

11 and 12 made to more closely abut each other in their closed position such that the rubber sealing strip on each movable section abuts the vertical surfaces of the other movable section along their adjacent forwardly extending sides and with the respective front half of the stationary member 13 alongthe rear transversely extending face of the movable members.

The storage cabinet A is suitably positioned above the floor by a base structure B which extends beneath the entire storage cabinet including the movable members and which supports the lower end of the hinge structure 21. The upper end of the hinge structure 21 is spaced from the stationary section 13 of the storage cabinet by means of a generally V-shaped bracket 23 affixed to its topmost edge and overlying the forwardly projecting member 15. The hinge structure itself comprises a rod, not seen, affixed to the base and to the V-shaped bracket at opposite ends and surrounded by three sections of a tubular member 24 to form a piano type hinge, the upper and lower sections of which are attached to the left hand movable section 11 and the middle section of which is attached to the right hand movable section 12. Each movable section has a door handle 25 of more or less conventional design afiixed to its outer side surface adjacent the front surface of the box and adapted to cooperate with suitable latch mechanism to hold the sections in their closed positions.

The storage cabinet A may be refrigerated in any convenient manner. The refrigeration system shown comprises a section of cooling coils 30 afiixed to the inside of the surface of the enameled liner 31 of each of the

movable sections

11 and 12 and a section of cooling coil 32 afiixed to the inside of the enameled liner of the stationary section 33, which are supplied with a refrigerant from a more or less conventional refrigerating unit C located in the base B of the refrigerator. The refrigerating unit C comprises a compressor 34 suitably driven by a motor 35, the discharge of which compressor is connected to a condenser-receiver 36. Liquid refrigerant from the condenser-receiver is bled to the cooling coil 30 of the right hand movable section 12 through a flexible connection 37 extending through a hole in the forwardly projecting member 16 and is conducted from the cooling coil 30 in the right movable section to the cooling coil 30 of the left movable section by another flexible connection 38. Refrigerant from the left movable section passes through another flexible connection 40 extending through member 16 to stationary piping 41 in the base of the refrigerator connected to the cooling coil 32 of the stationary section which in turn is connected to the compressor 34 to complete the refrigeration circuit.

One or both of the

movable sections

11 and 12 might be closed off by a system of doors along their two side surfaces which normally lie inwardly of the cabinet to form freezer compartments. In addition, sliding or other types of doors might also be provided along the front face of the stationary section 13 and the whole cabinet used as a food freezer. Particular advantage will be seen in providing doors for the internal sides of each of the compartments, whether the appliance is used as a refrigerator or a food freezer in that cold air will be retained in each of the cabinet sections when the storage cabinet is open and the operating expense of the appliance thereby reduced. However from the standpoint of convenience the omission of such doors is desirable.

From the foregoing description of the preferred embodiment of the invention, it will be apparent that the objects heretofore enumerated, as well as others, have been accomplished and that there has been provided a new and improved storage cabinet for refrigerators, food freezer appliances, and the like in which sections or compartments of the cabinet are made movable so as to provide better access to the contents of the cabinet.
