Specific reference is now made to the drawings wherein similar reference characters are used for corresponding elements throughout. It will be understood that any suitable materials may be used to fabricate the various parts.
The refrigerator is generally indicated at 10 and comprises adjacent sections 12 and 14 and doors 16 and 18 preferably designed with handles which may be individually locked. While two sections only are illustrated, it will be understood that additional sections may be added with a minimum of manipulative skill due to the standardization of sizes and shapes of the various parts and the special features of construction, as will appear hereinafter.
The refrigerator includes a base 20 of welded angle bars serving as a support. In the sectional unit shown, one portion of the base is enlarged to receive a preferably roll-out compressor 22. However, if a remote compressor is used the shorter section 12 will be made as long as the section 14.
The sections include an outer wall consisting of adjacent rear walls 24 and 26, opposed side walls 28 and r 30, roof walls 32 and 34 and bottom walls 36 and 38, the rear, roof and bottom walls being preferably integral and substantially C-shaped. All around the meeting edges of the C-shaped members there are inwardly extending abutting flanges 40 and 42 which are secured together by appropriate fasteners 44, there being included a reinforcing angle 46. This produces smooth rear vertical, top horizontal and bottom horizontal seams.
The upper ends of the side walls 28 and 30 are preferably rounded and are secured to the roof walls 32 and 34 by inwardly extending abutting flanges 48 and 5*!) which are secured to each other as at 52. The rear vertical corners of the refrigerator are reinforced with vertical channel pieces 54, the latter being secured as at 56 to abutting flanges 58 and 60 extending inwardly from the side walls 28 and 30 and the rear walls 24 and 26 respectively. Thus the construction is such .that a sectional refrigerator results having smooth seams as at 62 having no exterior screws.
All around the front edges of the side walls, the roof walls, and the bottom walls are flanges 64 to which are attached as .at .66 .a channel member .68 having an inwardly angulated lip 70, the channel member framing the entire front open end of the refrigerator behind the doors.
The sections include inner liners 72 and 74 each in the form of a shell with curved corners extending as a unit around and spaced from the side, roof and bottom walls. The liners are secured to the channel members 68 at the front end of the refrigerator. All around the front end of each liner is an angulated lip 76 which aligns with the lip 76 of the channel member and is secured thereto by a fiat member 78, preferably of Masonite, abutting the lips and 76. Screws 80 are used to attach the member 78 to the lips. Any desired insulation 82, such as fiberglass, may be interposed between the liners and the outer walls. The bottoms of the liners are additionally supported by substantially rigid heat-insulating strips 84, such as Celotex strips.
Secured in the channel members 68 all around the front of the refrigerator sections is a curved metal or plastic finishing piece 86 serving as a door frame. jacent one end of the piece 86 is a substantially L-shaped channel lip 88 into which is press fit the angulated crimped lip 90 of a bracket 92, the latter being secured by one of the screws 80 to the fiat bar 78. The bracket 92 serves to lend rigidity to the finishing piece 86 and also to keep the latter properly spaced from the bar 78. Received in the channel members 68 and in the finishing piece 86 are relatively rigid strips 94 of heat insulating material, such as Styrofoam, a perforated polystyrene plastic.
The doors 16 and 18 are hinged as at 96 to the side walls 28 and 30 at their front ends and consist of conventional face plates and inner shells filled with insulating material.
The partition between adjacent sections is spaced walls 98 and 100 between which are mounted a conventional fan 102 and an evaporator 104 operatively connected to the compressor 22, there being intake and return vents 106 and 108 in each partition wall.
At their rear vertical edges the liners 72 and 74 include flanges 110 and 112, see Figure 6, which abut against a vertical channel member 114, the partition walls 98 and 100 being secured as at 116 and 118 to the legs of the channel member. At the front of the refrigerator another vertical channel member 120 is provided and the front ends of the partition walls 98 and 100 are secured to this channel as at 122 and 124.
Additional liner sections 126 and 128 are provided which abut against the channel member 120, these liner sections being of the same construction as the liners 72 and 74 previously described and being secured to the flat bars 78, the channel members 68 and the finishing pieces 86 also in the manner as previously described.
An important feature of the present invention is the means by which the interiors may be made adjustably interchangeable. This is accomplished by providing pairs of vertical posts 130 which are secured interiorly of the refrigerator to the side portions of the inner liners and to the partition walls. The posts include vertically spaced, preferably square, openings 132, the posts being positioned so that the openings are in horizontal alignment.
The post is C-shaped and there is provided a number of insert brackets 134 slidable in the post, each bracket including legs 136 bearing against the legs of the post and a central plate 138 having a tapered recessed opening 140. After insertion of each bracket in the post, the flanges of the post are crimped as at 142 about the plate 138 to retain the opening in fixed alignment with one of the openings 132 in the post. A screw 144 is inserted through the opening 132 and then through the opening 140 of the bracket 134, the screw extending through the liner or partition wall, as the case may be. The head of the screw is disposed inwardly of the post to permit exposure of the openings 132.
Various members may be removably suspended in selected post openings 132 to support a variety of stationary, slide or roll-out food-retaining members. One such member is shown in Figures 13-15 and comprises a substantially V-shaped clip 146 having a substantially horizontal leg 148 and a vertically extending inclined leg 150. The leg 148 has a depending finger'152 adapted to engage in one opening 132 and the leg 150 has a finger 154 which engages in an opening 132 just beneath the aforementioned opening as shown in Figure 14. The leg 148 has an upstruck finger 156 serving to suspend a wire shelf 158.
In Figures 16-19 is shown another suspending member, the same comprising a channel rail 160 having front and rear terminal portions 162 and 164. The front portion has a downwardly opening outstruck finger 166 which is inserted in a selected opening 132, the finger having a shoulder 168 bearing on the lower edge of the opening. Above the finger is a stop 176 which also enters the opening 132 and serves to limit upward movement of the front end of the rail. The rear portion 164 of the rail includes an outstruck finger 172 opening towards the rear of the refrigerator and engaging in an aligned opening 132 in a rearwardly opposed post 130 as shown in Figure 17. The finger 172 has a shoulder 174 which bears against the rear vertical edge of the opening 132.
Thus the rails may be quickly and securely mounted in adjusted position on the posts in the interior of the refrigerator. A pair of such rails can serve to slidably support a bakers tray, such as 178.
The channel rail shown in Figures 20-22 is essentially the same as the slide rail shown in Figures 16-19 except that it is provided at its forward end with a roller 182. This roller engages the top of a channel side member 184, the latter including adjacent its rear a roller 186 engaging the lower flange 188 of the rail 180. Thus a pair of rails 180 can be quickly and adjustably installed in the interior of the refrigerator and upon these rails can be supported roll-out shelves 190, roll-out meatsuspending racks 192 and roll-out refrigerated drawers 194, all of which are conventionally provided with rear rollers 186 and stops to limit the movement of these members. I
