Refrigerator compartment housing vertically adjustable shelves, each formed from a piece of tempered glass to which is injection molded a frame in the form of front and rear border members

1. A refrigerator compartment comprising substantially parallel side walls and a rear wall therebetween, a plurality of substantially vertically spaced shelf-supporting ledges along each of said side walls, said shelf-supporting ledges being disposed in substantially horizontally aligned pairs, at least one slidable shelf defined by a piece of glass and front and rear border members each made of a single piece of substantially homogeneous polymeric/copolymeric molded synthetic material, said glass piece having opposite side edges and opposite front and rear edges, said front and rear border members each being of a substantially U-shaped configuration defined by a border bight portion and opposite substantially parallel side border portions having respectively a glass piece front edge-receiving channel and a glass piece rear edge-receiving channel, said opposite side border portions of said front and rear border members being in opposing relationship to each other, said front edge-receiving channel merging with side edge-receiving channels of said front border member side border portions, said rear edge-receiving channel merging with side edge-receiving channels of said rear border member side border portions, said channels front and rear edge-receiving channels and said side edge-receiving channels of said front border side border portions and said rear border side border portions open in opposing relationship to each other, said glass piece front, rear and side edges being received in the respective glass piece front edge-receiving, rear edge-receiving and side edge-receiving channels, said at least one slidable shelf being disposed with said front and rear border members in sliding relationship to one of said horizontally aligned pair of shelf-supporting ledges with said piece of glass being thereby spaced above said horizontally aligned pair of shelf-supporting ledges, and at least a portion of each glass piece side edge disposed between said front and rear border members side border portions being substantially completely exposed whereby air flow within the refrigerator compartment is enhanced.

2. The refrigerator compartment as defined in claim 1 including a space between each shelf-supporting ledge and an associated exposed glass piece side edge portion to effect air flow therebetween thus further enhancing conductivity within the refrigerator compartment.

3. The refrigerator compartment as defined in claim 2 wherein said opposite side border portions of said front and rear border members are supported by said ledges.

4. The refrigerator compartment as defined in claim 2 wherein said front and rear members are injection molded upon and are thereby bondingly secured to said respective glass piece front and rear edges.

5. The refrigerator compartment as defined in claim 2 wherein said front and rear members are injection molded, and adhesive means for bondingly securing said front and rear members to said respective glass piece front and rear edges.

6. The refrigerator compartment as defined in claim 2 wherein said front and rear border members are each in situ injection molded in bonded relationship to said piece of glass.

7. The refrigerator compartment as defined in claim 1 wherein said opposite side border portion of said front and rear border member are supported by said ledges.

8. The refrigerator compartment as defined in claim 7 wherein said front and rear border members are each in situ injection molded in bonded relation to said piece of glass.

9. The refrigerator compartment as defined in claim 1 wherein said front and rear members are injection molded upon and are thereby bondingly secured to said respective glass piece front and rear edges.

10. The refrigerator compartment as defined in claim 1 wherein said front and rear members are injection molded, and adhesive means for bondingly securing said front and rear members to said respective glass piece front and rear edges.

11. The refrigerator compartment as defined in claim 1 wherein said front and rear border member are each in situ injection molded in bonded relationship to said piece of glass.

12. A slidable shelf particularly adapted for use in a refrigerator compartment comprising a piece of glass and front and rear border members each made of a single piece of substantially homogeneous polymeric/copolymeric molded synthetic material, each front and rear border member having a lower support surface adapted for sliding support in an associated refrigerator compartment; said glass piece having upper and lower surfaces, opposite side edges and opposite front and rear edges; said front and rear border members each being of a substantially U-shaped configuration defined by a border bight portion and opposite substantially parallel side border portions having respectively a glass piece front edge-receiving channel and a glass piece rear edge-receiving channel, said opposite side border portions of said front and rear border members being in opposing relationship to each other, said front edge-receiving channels of said front border channel merging with side edge-receiving channels of said rear border member side border portion, said channels front and rear-receiving channels and said side edge-receiving channels of said front border side border portions and said rear border side border portions open in opposing relationship to each other, said glass piece front, rear and side edges being received in the respective glass piece front edge-receiving, rear edge-receiving and side edge-receiving channels, and at least a portion of each glass piece side edge disposed between said front and rear border members said border portions being substantially completely exposed with said glass piece lower surface being spaced above a plane through said front and rear border member lower surfaces whereby air flow within an associated refrigerator compartment is enhanced.

13. The shelf as defined in claim 12 wherein said glass piece front and rear edges define with said glass piece side edges corner portions of said glass piece, and said corner portions are substantially encapsulated by said front and rear border members.
