(Cl. 211--153) This invention relates to domestic `refrigera» tors and more particularly to food supporting shelves for domestic refrigerators. Food supporting shelves used in domestic re frigerators heretofore have generally been made 2 tom portion of the channel by means of a screw 5 which passes through an elongated opening in the bottom of the channel and permits adjust ment of the end blocks. _ A plurality of relatively thin strips E made of entirely of metal, A metal shelf is objectionable plastic or other light weight material spans the in that it is expensive, heavy and difficult to space between the longitudinal sides of the rec clean. tangular frame member and act as food support The objects of this invention are to overcome the above objections by providing a refrigerator 10 ing surfaces. These strips are provided with notched end portions 'I at each end thereof which shelf that is relatively light, constructed of in extend into the channel of the frame member as expensive materials, easily fabricated and easily shown in Figs. 3 and 4. Spacing blocks 8 made cleaned. ' These objects are carried out by providing a re frigerator shelf made up of a rectangular outer of plastic or other light weight material are lo cated between the ends of the transversely ex tending strips 6. The spacing blocks 3 are pro vided with slots 9 and I lì in their upper and lower the cross-section of which is C-shaped. The faces respectively by which they are held in as food supporting surface consists cf a plurality of sembled position on upper and lower1 flanges Il thin light weight strips, such as strips of plastic, and I2 of the channel member 2. which span the space between the longitudinal 20 _A locking block I3 made of plastic or other sides of the rectangular frame. These strips are light weight material is located between two cen supported by and anchored to the rectangular ter strips 6a and 6b mid-way along each longi frame member. tudinal side of the rectangular frame. The A specific embodiment of my invention is blocks I3 are provided with flanges I4 at the shown in the accompanying drawing in which: upper front portion thereof and with a cut-away Fig. 1 is a perspective View of a part of the portion I5 at the lower front portion. Each of food storage space of a refrigerator cabinet show the locking blocks I3 is provided with a threaded ing my improved food supporting shelf located opening IB extending therethrough which is frame member constructed of light weight metal, therein; Fig. 2 is a plan view of a specific embodiment of my improved shelf; Fig. 3 is a vertical sectional view taken on line 3--3 of Fig. 2; Fig. 4 is a plan view partly in section showing a corner of the shelf shown in Fig. 2; and Fig. 5 is a perspective view of one side of the shelf as viewed in the direction of arrow 5 in adapted to receive a screw I 'I which in turn passes through an opening I8 in the bottom por tion of the rectangular frame member 2 as viewed in Fig. 5. ` An inverted U-shaped reinforcing member I 9 made of relatively light weight metal extends through the length of the shelf at the mid-por tion thereof. This member is provided with a slotted portion 2Q at each end to receive a screw Fig. 2 showing the elements in extended rela ZI whereby the member is attached to the trans tionship and illustrating the manner in which verse ends of the rectangular frame 2. Rein _they are assembled. 40 forcing member I9 is also provided with a plu Referring to the drawing wherein like refer rality of equally spaced slots 22 extending ence characters denote like parts, I designates throughout its length. These slots are adapted generally my improved food supporting shelf to receive and support the transverse strips 6 at adapted to be supported in any convenient man their mid-portions. ' ner in the food storage space of a refrigerator 45 The shelf is assembled by first forming the -cabinet as shown in Fig. l. channel frame member 2 as a closed rectangle This shelf is made up of a rectangular frame with mid-longitudinal portions of the lower 4member 2 constructed of a light weight metal ñange I2 cut away as shown at 3 of Fig. 5. Then channel member which is C-shaped in» cross the end blocks 4 are attached to the corners of .section as shown in Figs. 3 and 5. At the mid the rectangular frame by screws 5 as shown in portions of the longitudinal sides of the frame Fig. 4. Now, starting with the left han of the " Amember a lower flange I 2 is cut away as shown at rectangular frame as viewed in Fig. 2, for ex 3 in Fig. 5. The rectangular frame member is ample, one of the notched ends of a supporting provided at each of its four corners with a wedge shaped end block 4 which isattached tothe bot-_- 55 strip 6 is inserted into the cut away portion of the channel member 2, 'then with the strip ex- 2,407,721 3 tending at an angle other than 90° to the face of the longitudinal side of the frame member, 4 at the inner side thereof, a plurality Vof thin strips spanning the space between two sides of said frame, said strips having end portions which the opposite notched end of the transverse strip bear against said flanges and extend into said is inserted into the out away portion at the op channel member, and spacing blocks extending posite side of the rectangular frame. Then this Ol into said channel between the ends of each pair strip is moved toward the left of the frame with of said strips, said spacing blocks and channel the notches fitting over upper and lower flanges having interengaging parts to retain the Áblocks Il and l2 of the channel until the strip con tacts the end blocks 4 at each side of the left end of the frame. Now, a spacing lblock 8 is in serted into the cut away portion of the frame member at each side thereof and With the slots 9 and l0 of the block fitting over the flanges ll and l2 respectively of the channel member, the blocks are each moved along the channel meme in position on the channel. 4. A food supporting shelf comprising a rec tangular frame constructed of an inwardly-fac ing channel member, a plurality of strips extend ing transversely of said frame, said strips having end portions which extend into said channel member which anchor said strips against trans verse movement relative to said frame, and spac ber until they contact the ends of the previously ing blocks located in said channel between the inserted strip 6. This procedure, ñrst a strip 5 ends of each pair of strips anchoring said strips and then a spacing block 8 at each end of the against longitudinal movement relative to said strip, is continued until the left half of the shelf frame, said spacing blocks and channel member 20 is completed. Then the right half of the shelf having interlocking tongues and grooves to re is assembled in a similar manner. ith all of tain the blocks in position on the member. the `transverse strips 6 and the spacing blocks 8 5.
