13 Claims. c1. 220-16) This invention relates generally to refrigerator cabinets and refers more particularly to improvements in cabinets especially adapted for use in connection with home freezers.

It is an object of this invention to provide a home freezer cabinet structure having separate storage compartrnents accessible through openings at the top of the cabinet and constructed to afford more storage area for a cabinet of given size than heretofore obtainable.

It is another object of this invention to provide a home freezer cabinet wherein the access openings are separated by a mullion extending from one side of the cabinet to the opposite side and overlying the top of one of the compartments. Thus, the mullion forms an abutment for the adjacent ends of doors for the access openings and the space beneath the mullion is available for storage purposes.

It is still another object of this invention to provide a home freezer cabinet structure of the above general type wherein the adjacent walls of the liners forming the storage compartments are secured in face to face contact and thereby occupy a minimum space within the cabinet.

The foregoing as well as other objects will be made more apparent as this description proceeds especially when considered in connection with the accompanying drawings, wherein Figure 1 is a fragmentary top plan view of a home freezer cabinet having the doors removed;

Figure 2 is an enlarged fragmentary top plan View partly broken away for the sake of clearness;

Figure 3 is a fragmentary sectional view taken substantially on the line 33 of Figure 2;

Figure 4 is a cross sectional view taken on the line 4-4 of Figure 2;

Figure 5 is a sectional view taken on the line 5-5 of Figure 2;

Figure 6 is a cross sectional view taken on the line 66 of Figure 2; and

Figure 7 is a sectional view taken on the line 77 of Figure 2.

Referring now more in detail to the drawings, the numeral 10 in Figure 1 designates a home freezer cabinet having an outer shell 11, a pair of upwardly opening storage compartments 12 and 13 within the confines of the shell 11, and separate doors 14 for the respective storage compartments. The shell 11 is open at the top and has a front side wall 15, a rear side wall 16, end

walls 17 and a bottom wall, not shown herein. The side and end walls of the shell 11 are turned inwardly at the top, then outwardly to provide marginal flanges 18 of double thickness, then downwardly along the inner surface of said walls, and then again inwardly to form flanges 19 spaced below the flanges 18.

The compartment 12 is formed by a liner 20 having side walls 21, end walls 22, and a bottom wall, not shown. The compartment 13 is formed by a similar liner 23 also having side walls 24, end Walls 25 and a bottom wall, not shown. The two liners are positioned within the shell in any suitable manner not shown in detail herein.

11 and are secured to the shell in side by side relationship The adjacent end walls 22 and 25 of the liners are welded or otherwise secured together in surface to surface contact throughout substantially the entire area thereof, and the remaining walls of the liners are spaced from the adjacent walls of the shell to accommodate thermal insulating material 26. The top edges of the liner walls are spaced below the top edges of the walls of the shell, and strips 27 are welded to the outer surfaces of all the walls of the liners except the walls 22 and 25. The strips 27 extend downwardly from the top edges of the liner walls aforesaid and the lower ends are fashioned to provide laterally outwardly opening channel-shaped sections 28, as shown in Figures 3 and 5 of the drawings.

The space between the walls of the shell 11 and the adjacent walls of the liners is bridged above the thermal insulation 26 by a frame 29 of heat resistant material having the inner marginal edge extending into the channel-shaped portions 28 of the strips 27 and seated on the bottom flanges of said portions. The outer marginal edge of the frame overlies the flanges 19 on the shell 11 and is secured to the flanges 19 by spring clips 30. As shown in Figures 2, 5 and 7 of the drawings, the frame 29 has separate center sections 31 at opposite sides and intermediate the ends of the frame. The sections 31 have depressed central portions 32 which afford clearance for the opposite ends of a mullion 33 about to be described.

The mullion 33 provides an abutment for the adjacent ends of the closures 14 and is positioned within the liner 20 at the top of the compartment 12, as shown in Figure 4 of the drawings. In other words, the mullion is not interposed between the adjacent end walls 22, 25 of the liners or storage compartments as is the usual practice, but on the contrary overlies the top of the storage conipartment 12 so that the space within the compartment 12 directly below the mullion may be used for storage purposes. As a result, the mullion occupies little if any usable storage space and, hence, more storage area is provided in a cabinet of given size.

In detail, the mullion 33 includes a part 34 which extends between the opposite side walls 21 of the liner 2t and is formed of a moldable heat resistant plastic material. The part 34 is channel-shaped in cross section and is located within the top of the liner 20 with the channel opening in an upward direction. The upstanding flange 35 at the inner side of the channelshaped part 34 is in surface to surface engagement with the Wall 22 of the liner 20 (Figure 4), and the opposite ends of the part 34 have upstanding flanges 36 (Figure 5) which form continuations of the side flanges on the part 34. The flanges 36 respectively abut the end walls 21 of the liner 2t and are secured to the end walls 21 by fasteners 37. In addition, the part 34 is fashioned with an attaching flange 33 which projects laterally inwardly from the upstanding flanges on the part 34 and which extends continuously around said upstanding flanges.

The mullion 33 also has a second part 39 which extends lengthwise of the part 34 above the latter and which is also formed of a moldable heat resistant plastic material. The part 39 is channel-shaped in cross section and is positioned in the channel of the part 34 with the channel opening downwardly. The opposite ends of the part 39 have depending flanges 40 which form a continuation of the side flanges 41 on the part 39, and said depending flanges are turned laterally outwardly to form terminal flanges 42. The terminal flanges 42 are supported by the flange 38 on the part 34 and are attached to the flange 38 at spaced points by spring clips 43.

The above arrangement is such that the parts 34 and J 39 cooperate with one another to provide an enclosed space (Figures 4 and 5) for thermal insulating material 44. The enclosed space formed by the parts 34 and 39 may be sealed, if desired, by a plastic sealing com pound 45 applied as indicated in Figures 4 and 5 of the drawings.

The mullion 33 has a third part 46 channel-shaped in cross section and extending longitudinally of the part 39 above the latter with the channel opening upwardly. The opposite ends of the part 46 project beyond the ends of the part 39 and the base portion 47 of the part 46 overlies the flanges It? projecting inwardly from the walls 15, 3.6 of the shell 11, as clearly shown in Figure 5 of the drawings. it will also be noted from Figure 5 that strips 48 are welded to the undersides of the flanges 19 at opposite sides of the shell and that the inner ends of the strips 45: overlie the depressed portions 32 of the frame sections 31 as shown in Figure 7 of the drawings. The inner ends of the strips 48 are respectively secured to the sections 31 by screws 49 which extend downwardly through the base portions 47 of the channel-shaped part 46.

The upper ends of the flanges of the part as are turned laterally outwardly to form terminal flanges 59. The flanges 56 form a seat for a strip 51 of heat resistant lnoldable material which extends lengthwise of the part 46 and has longitudinally spaced depending projections 52 positioned to extend through openings formed in the flanges 56, as shown in Figure 6 of the drawings. The opposite ends of the strip Sll are otfset in a downward direction to provide flanges 53 (Figure 5) which extend beneath the flanges 18 at opposite sides of the shell ll. Suitable electrical resistance wires 54 are located within the channel of the part 46 in order to prevent frosting along the adjacent ends of the doors l4, and the outer ends of the wires extend through an insulator 55 located in the rear wall 36 of the shell 11 between the flanges l8 and 19.

The opposite longitudinal edges of the strip 51 project laterally outwardly beyond the flanges 50 to provide attaching portions 56 for breaker strips 57 and 53. The breaker strips are molded or otherwise formed of plastic heat resistant material and tie adjacent ends of the strips are formed with laterally opening grooves 59 for respectively receiving the portions 56 of the strip 51. As shown in Figure 4 of the drawings the breaker strips 57, 53 are curved downwardly from opposite side edges of the strip 51 and the lower edges of the breaker strips are offset laterally outwardly to form shoulders 66. The shoulder 6 on the strip 57 seats on the top edge of the adjacent side flange on the part 34 of the mullion, and the shoulder 60 on the strip 53 seats on the top edges of he walls 22, 25 and the flange 35 on the part 3 3 Thermal insulation 61 is provided in the spaces between the breaker strips and the part 39, as shown in Figure 4 of the drawings.

The space between the marginal edges of the flanges 18 on the shell and the top edges of the adjacent walls of the liner Tnli is bridged by a breaker strip 62, and the corresponding space between the flanges l8 and the top edges of the shell 23 is bridged by a breaker strip 63. In the present instance, the breaker strips 62 and 63 are respectively formed integral with the strips 57 and 58 associated with the mullion 33.

The doors 14 may be of any suitable construction and are not shown in detail herein. Each door is hingedly connected at its rear edge to the rear wall of the shell 11 by hinges (not shown) and a sealing gasket (i4 is secured to the .iarginal edge portion of each door, as shown in Figures 3 and 4. The portion of the sealing gaskets extending along the adjacent ends of the door seat against the portions of the strip 51 directly above the flanges Ell on the part 4% of the mullion 33 and the remaining portions of the gaskets 64 seat on the flanges of double tiickness. Thus, ex-

ccptionally rigid supports are provided for tie doors 14 when the latter are in their closed positions.
