DETAILED DESCRIPTION OF THE INVENTION

A baking oven1comprises a baking oven muffle2, which has two side walls3, which are connected to each other by a bottom4and a ceiling5. In an interior of the baking oven muffle2, there is a pull-out guide6on each side wall3, which is fixed to the side wall3or the ceiling5with a stationary guide rail7. On the guide rail7, a pull-out-extending middle rail8is movably mounted, on which a running rail9can be moved, the movable bearing being preferably provided by rolling elements. In the longitudinal direction of the pull-out guide6, the running rail9is designed to be shorter than the guide rail7and the middle rail8, in particular by more than 10%, preferably by more than 20%.

A side grid10is held to the running rail9, which has vertical posts11between which horizontal rods12run. The side grid10can be attached to the running rail9in a non-detachable way, e.g. by welding, or detachable, e.g. by clips, locking devices, screws or other detachable fasteners. Two horizontal rods12form a receptacle for an edge15of a cooking good carrier14, which in the design example shown is designed as a baking tray, whereby grids or other cooking good carriers can also be used. The rods12are angled at one end section13so that, in a front view as shown inFIG.1B, an edge15of cooking good carrier14can be inserted between two horizontal rods12. The upper horizontal rod12of a support has a downward projection16in the rear area, in particular a V-shaped projection, which forms an anti-tip device and prevents the cooking good carrier from tipping upwards in the rear area if it is loaded at a front side. Instead of the projection16, other holding devices can be provided for additional fixing of the cooking good carrier.

FIG.2Cshows that the cooking good carrier14has a downward protruding web or undercut150in the area of its edge15, which, when the cooking good carrier14is correctly positioned in the side grid10, rests against the angled front end section13of the lower rod12from both sides. The angled end section13is inserted in a receptacle152open at the bottom at the undercut150. On the one hand, this ensures that the cooking good carrier14cannot be pushed too far into the side grid10, and on the other hand it provides additional protection against tipping. The undercut150can have an insertion bevel151at least at the rear end area, which allows the cooking good carrier14to be easily pushed onto the rod. An insertion bevel151is preferably formed on both sides of the receptacle152.

FIG.2Dshows a cooking good carrier14with undercut150and insertion bevels151. The undercut150can be provided on opposite sides of the cooking good carrier14.

The cooking good carrier14is longer than the side grid10, particularly by at least 20%, preferably at least 30%, in the longitudinal direction of the pull-out guide6. The running rail9is approximately the same length as the side grid10, whereby the cooking good carrier14protrudes over the side grid10in a front area, whereas it is essentially flush with the side rail in the rear area.

InFIGS.1A and1Bthe cooking good carrier14is in a retracted position and the oven door can be closed.

If, when preparing food, access is required to part of cooking good carrier14, it can be moved to a middle pull-out position as shown inFIGS.2A and2B. In this middle pull-out position, a front section of cooking good carrier14, e.g. an area between 10 and 80%, is in front of the oven muffle2when viewed in the longitudinal direction of pull-out guide6, while the remaining part of cooking good carrier14is located in the oven muffle2, as shown inFIG.2B. In this middle pull-out position, the side grid10is still completely in the oven muffle2and thus does not pose a risk of injury. If the cooking good carrier14is now removed from this middle pull-out position, the oven door can be closed even if the running rail9and the side grid10are not in the maximum pull-in position. Preferably, latching devices are provided on the pull-out guide6and/or the side grid10in order to be able to latch the cooking good carrier14together with the side grid10in the middle pull-out position and thus provide holding forces which prevent the cooking good carrier14from moving inadvertently beyond this middle pull-out position. In this embodiment, the latching means are designed as recesses17in the side wall3of the oven1, in which a preferably spring-mounted roller18arranged on the vertical post11engages in the retracted, middle and extended positions. Instead of the recess17there could also be a detent projection or another detent element and instead of a roller18there could also be a projection, a spring element or similar latching means. Alternatively, latching means can be provided between guide rail9and guide rail7or between running rail9and side grid10.

If the user wishes to move the cooking good carrier14further in front of the oven muffle2, he can do so as shown inFIGS.3A and3B. By pulling the cooking good carrier14slightly, the latching means are disengaged and the cooking good carrier14can be moved. In this position, the side grid10is also located largely in front of the oven muffle. If the cooking good carrier14is now removed, the side grid10and the running rail9protrude relatively little from the oven muffle2. For example, the side grid10can have a length in the longitudinal direction of the pull-out guide6between 20% and 60% of the length of the cooking good carrier14. The cooking good carrier and side rack can be located completely in front of the oven muffle.

In the embodiment shown, the side grids10comprise a large number of horizontal rods12, each of which forms receptacles for a cooking good carrier14. It is of course possible to adapt and vary the number of so formed supports to the type of oven. In addition, the pull-out guide6can also be positioned to the side of the side grid or below the side grid10instead of above the side grid10.

In order to increase the stability of an oven1according to the invention, at least one synchronizing means19, e.g. as a sheet or as a rod, can be arranged between the right and left side grid10. The at least one synchronizing means19is preferably located in an area of the side grid10which is vertically spaced from the pull-out guide6. Additionally or alternatively, the two pull-out guides can also be connected to each other. Detachable or non-detachable fastening means can be provided for the synchronizing means19.

FIGS.4A and4Bshow a modified embodiment of an oven1with an oven muffle2. In the interior of the baking oven muffle2, a pull-out guide6is located on each side wall3, with a stationary guide rail7arranged below a movable running rail9. The running rail9can be shorter than the guide rail7in the longitudinal direction of the pull-out guide6. A modified side grid10′ is held to the running rail9, which has vertical posts11and horizontal rods12.

The side grid10′ has a profile24in the area of the pull-out guide6, in particular a U-shaped profile24on which a support25is formed. This means that the support25can be supported on the running rail9, so that additional fastening of the side grid10′, as is required for a suspended arrangement on an underside of the pull-out guide6, is not necessary. The support25can be placed loosely on the running rail9, whereby optional fixing is of course possible. The fixing can be either detachable, e.g. by clipping or screwing, or non-detachable, e.g. by welding.

To secure the cooking good carrier14to the side grid10′, it has an upwardly directed projection26on the lower horizontal rod12of each of the two horizontal rods12, between which an edge15of the cooking good carrier14is held, which engages from below in a corresponding recess27on the edge15of the cooking good carrier14. Instead of a projection26, there may also be a pin or embossing.

FIG.5shows a further embodiment of an oven1with an oven muffle2, in which two pull-out guides6are provided at the bottom of the oven muffle2. It is also possible to use only one pull-out guide6instead of the two pull-out guides6, which then carries two side grids10″.

The pull-out guide6support a support20, which supports a side grid10″ on opposite sides. The support20has two upwardly projecting legs21for this purpose, although other designs of the support20can also be provided for fixing the side grids10″.

For the latter two embodiments, all the features described in detail for the first embodiment are also valid with regard to rail lengths, cooking good carrier and side grid positions, latching elements and synchronization means.

Each of the illustrated pull-out guides6can have a cover element not shown in the rear area of the guide rail. The cover protects the inside of the pull-out guide6from contamination and serves as a stop for the running rail9when retracted.

FIG.6shows the oven shown inFIGS.1to3in a modified design. In addition to the embodiments described above, a spring element30in the form of a bending spring is arranged between the oven muffle2and the cooking good carrier14. The spring element30is connected to the oven muffle at one end31, e.g. by a holder. At the opposite end, a connecting piece32is provided which rests on the cooking good carrier14and is detachably connected to the cooking good carrier14. The spring element30allows the cooking good carrier14to be moved automatically in the opening direction from the closed position shown inFIG.1Awhen the oven door is opened. The travel movement generated by spring element30facilitates access to the cooking good carrier14. Starting from this position, the cooking good carrier14can then be moved further in the pull-out direction or moved again in the closing direction either directly or via the oven door.

The spring element30is located between a back wall of the oven muffle2and the cooking good carrier14. Alternatively, the spring element30can also be provided between the oven muffle2and the side grid10or between the guide rail7and the running rail9. In any case, the cooking good carrier14is directly or indirectly pretensioned in the opening direction via the spring element30, whereby in the closed position the oven door holds the cooking good carrier14in the draw-in position. At a contact area between the cooking good carrier14and the oven door, an elastic stop element can be provided, e.g. at the edge15, in order to avoid stop noises.
