- a pair of upper and lower engagement members located on each of two opposing sides of said shelf or rack, where each engagement member is capable, in use, of engaging with said enclosure support means to support said shelf or rack,
- such that when said upper engagement means are engaged with a pair of support means said shelf or rack is supported at a lower height in said enclosure than when said lower engagement means are engaged with the same pair of support means.
- In a second aspect the invention consists in a shelf or rack for an oven which includes at least one pair of support means on opposite side walls of said oven for supporting said shelf or rack, said shelf or rack having:
- a pair of upper and lower engagement members located on each of two opposing sides of said shelf or rack, where each engagement member is capable, in use, of engaging with said oven support means to support said shelf or rack,
- such that when said upper engagement means are engaged with a pair of support means said shelf or rack is supported at a lower height in said oven than when said lower engagement means are engaged with the same pair of support means.
- In a third aspect the invention consists an oven having a rack or shelf, said oven including at least one pair of support means on opposite side walls of said oven for supporting said shelf or rack, said shelf or rack having:
- a pair of upper and lower engagement members located on each of two opposing sides of said shelf or rack, where each engagement member is capable, in use, of engaging with said oven support means to support said shelf or rack,
- such that when said upper engagement means are engaged with a pair of support means said shelf or rack is supported at a lower height in said enclosure than when said lower engagement means are engaged with the same pair of support means.
- To those skilled in the art to which the invention relates, many changes in construction and widely differing embodiments and applications of the invention will suggest themselves without departing from the scope of the invention as defined in the appended claims. The disclosures and the descriptions herein are purely illustrative and are not intended to be in any sense limiting.
- FIG. 1 is a partial perspective view of an oven side wall and shelves of the present invention,
- FIG. 2 is a side elevation in partial cross-section of an internal side wall of an oven showing the interaction between the runners and shelves, and
- FIG. 3 is a partial front elevation in partial cross-section of an oven side wall and shelves.
- The shelf system of the present invention comprises a tray or wire shelf or rack having double running surfaces on two opposing sides, which in use provide support for the shelf on the runners provided within an oven cavity. The shelf may be placed within an oven and slid over the runners formed on opposite side walls of the surface liner of the oven. The top most surface of the shelf can be supported by a runner on either side of the oven, or alternatively, the bottom most running surface can be supported by a runner on either side of the oven. Therefore the shelf may be placed in the oven where the runner is between the double running surfaces, or the double running surfaces may allow for the placement of the shelf between two runners. Therefore the number of shelf positions within the oven cavity may be up to double that provided in conventional ovens. Furthermore, the shelf system of the present invention also provides a finer adjustment for positioning the shelf within an oven.
- Referring to FIG. 1, an
oven liner 1 is provided within the cavity of an oven. This liner is usually a steel cavity, but may be made from other materials. A series of support means 2, are located on the vertical sides of theoven liner 1. The support means are protrudingrunners 2 in the preferred form of the present invention, but may be solid elongate members in lesser preferred forms. The pairs ofrunners 2 line up horizontally across theoven cavity liner 1 to provide a level surface for a shelf orrack 3. The shelf orrack 3 has amain body 3 a and upper 4 and a lower 5 engagement members that in the preferred form of the present invention are elongate running surfaces. The spacing between of therunners 2 and the spacing between the upper 4 and lower 5 running surfaces must be of a corresponding space, or at least the spacing between each runner must be of a similar width to (but not necessarily equal to) the width of the double running surface of the shelf. Alternatively, in less preferred forms of the present invention, supports may be provided within an enclosure where a shelf or rack with double running surfaces can, in use, be supported within the enclosure. - Referring to FIGS. 2 and 3, the shelf of the present invention may be placed in a number of positions within an oven. When the
shelf 3 is placed in a first location within the oven, the upper runningsurface 4 of theshelf 3, sits on theupper level 6 of therunner 2. As shown in FIG. 2 the topmost shelf is placed in such a position. In this position, to prevent tilting of the shelf when withdrawn from the enclosure the runningsurfaces tilts surfaces upward tilt 7 of the lower runningsurface 5 catches on thenode 8 in therunner 2. When theshelf 3 has reached its full extension,node 8 andtilt 7 meet and prevent theshelf 3 from being fully removed from the oven and theshelf 3 is restricted from tilting up or down, particularly at times where there is weight placed on the shelf. - When the shelf is in use in a second position, namely between a
first runner 9 and asecond runner 10, the lower runningsurface 5 sits on the upper level 11 of the lower 10 of the two runners. In this position, theupward slope 12 of the upper runningsurface 4 catches on thenode 13 in theupper runner 9 when theshelf 3 has reached its full extension, thus preventing the shelf from being fully removed from the oven. - The front of each runner angles back from the node thereby reducing the width of the runner. The angle of the runner in front of the node corresponds to the angle of the upward slope on both running surfaces of the shelf, such that the shelf can be inserted or removed from the oven cavity by lifting the front of the shelf upwards.
- The
shelf 3 may be a wire rack configuration or be of a tray configuration. In either of these forms the upper running surface is connected to the lower running surface by way of anangular connector 14. Thisconnector 14 also connects the double running surface to themain body 3 a of the shelf. Preferably the angular connector is made of wire, but may be made of a sheet type or other appropriate material. - The advantages of this system are that the shelf of the present invention provides for finer shelf adjustment to allow for the positioning of food at an optimum cooking height within the oven cavity. In the past achieving optimal cooking heights has been difficult when using conventional oven cavities with formed runners. Furthermore, in the preferred form, the rack system of the present invention has two safety features. Firstly, the system has a stopping mechanism to prevent the shelf from being fully withdrawn, and secondly it has an anti-tilt mechanism to prevent the shelf from tipping. To achieve these safety features there is a requirement that the spacing of the runner forms and the spacing of the running surfaces on the shelf correspond and the shelf is provided with an upward tilt in the rear section of the shelf.
