DETAILED DESCRIPTION
[0052] FIG. 1 shows a cross-section through an angled refrigerator shelf 1. The shelf 1 has a riser 2 attached to an edge of the shelf 1. In use, the riser 2 impinges on the air curtain of a refrigerator, as the riser protrudes into the air flow of the air curtain.
[0053] FIG. 2 shows a cross-section through an angled refrigerator shelf 1. The shelf 1 has an angled riser 3 attached to an edge of the shelf 1. The angle of the angled riser 3 helps to prevent the riser from impinging on the air curtain of a refrigerator in use. If an air guide is also attached to the edge of the shelf 1, this can prevent shoppers from viewing produce on a shelf sited below the air guide.
[0054] FIG. 3 shows a bracket 5 for holding an air guide. The bracket 5 may be S-shaped, a chicane shape or a swan-neck shape. Alternatively, the bracket may comprise a rectangular cross-section or be any other shape that translates the angled edge of the shelf such that an air guide coupled to the end of the bracket not engaged with the edge of the shelf is parallel to an air curtain of a refrigerator in use. An angled surface 9 of the bracket can be coupled to an edge of a refrigerator shelf. As seen in FIGS. 1 and 2, due to the angle of the refrigerator shelf, the edge of the refrigerator shelf is at an angle to an imaginary vertical line. The angled surface of the bracket may match this angle. This causes the second end of the bracket comprising, for example, a clip 6 for coupling to an air guide to be parallel to a vertical air curtain in use. The bracket translates the angled edge of the shelf, so that an air guide coupled to the clip is parallel to the air curtain in use. The clip 6 may comprise a first end 7 for retaining a leading edge of an air guide and a second end 8 for retaining a trailing edge of an air guide. The bracket may also comprise an angled slot for retaining an angled riser. This slot may be angled such that it is parallel to the angled surface 9.
[0055] FIG. 4 shows a broadly similar bracket 5 to the bracket shown in FIG. 3. In this embodiment, the bracket further comprises a vertical slot 12 for retaining a riser with a rectangular cross-section. In use, this prevents the riser from impinging on an air curtain.
[0056] FIG. 5 illustrates schematically the bracket 5 of FIG. 3 in use. The angled surface of the bracket is attached to the edge of an angled refrigerator shelf 1. As can be seen, the bracket 5 translates the angled edge of the shelf to a clip that can retain an air guide parallel to an air curtain. Further, the air guide is moved above the edge of the angled shelf 1, thereby improving the view of items stored on a shelf below. The bracket 5 may comprise an angled slot for receiving a first end 4 of an angled riser 3, such that the second end of the riser is parallel with an air curtain in use and does not impinge the air curtain.
[0057] FIG. 6 illustrates schematically the bracket 5 of FIG. 4 in use. The angled surface of the bracket is attached to the edge of an angled refrigerator shelf 1. As can be seen, the bracket 5 translates the angled edge of the shelf to a clip that can retain an air guide parallel to an air curtain. Further, the air guide is moved above the edge of the angled shelf 1, thereby improving the view of items stored on a shelf below. The bracket 5 may comprise a slot for receiving a first end of a riser with a rectangular cross section 2, such that the second end of the riser is parallel with an air curtain in use and does not impinge the air curtain.
[0058] FIG. 7 shows a solution, as provided by the present invention, to the problem associated with attaching air guides to the edges of angled shelves in a refrigerator. The open display refrigerator 10 has angled shelves 1, comprising a riser 3 and a bracket 5. The bracket 5 comprises a clip 6, which comprises a first end 7 for retaining a leading edge of an air guide 11 and a second end 8 for retaining a trailing edge of the air guide 11. As can be seen, by raising the air guide 11 from the edge of the shelf, it is easier for a user to view products on the angled shelf below an air guide 11 due to the increase in space between the lower edge of the air guide 11 and the top surface of the shelf below the air guide 11.
[0059] FIG. 8 shows an angled shelf 1, with an edge at an angle 13. The bracket 5 has a surface also at an angle 13, which matches the angle of the edge of the angled shelf. The desired angle 14 is the same as the angle 13.
