The invention relates to a width-adjustable carrier frame (1) which can be used in household appliances, particularly cooking and baking ovens, for receiving and supporting a grilling rack (13), a tray, a dish (15), a cooking or baking sheet, or the like. According to the invention, the carrier frame (1) consists of at least two cross members (2) with tube-type front-side end areas as well as of two approximately U-shaped carrying bows (3), at least one carrying bow (3) being continuously movable relative to the cross members (2) by means of a worm drive. A carrier frame (1) designed in this manner can be comfortably adapted by the operation of the worm drive to interiors of different widths of household appliances. This permits a continuous adaptation in a simple manner. If required, the carrier frame (1) can also virtually be pressed onto the interior walls of a household appliance by means of the worm drive and can therefore be force-lockingly fixed and thus sufficiently secured against an unintentional pulling-out.
Width-adjustable carrier frame (1) usable in household appliances, particularly in cooking and baking ovens, for receiving and supporting a grilling rack (13), a tray, a dish (15), a cooking or baking sheet, or the like, characterized in that the carrier frame (1) consists of at least two cross members (2) with tube-type front-side end areas as well as of two approximately U-shaped carrying bows (3), and in that at least one carrying bow (3) is continuously movable relative to the cross members (2) by means of a worm drive.
Carrier frame according to one or several of the preceding claims, characterized in that the carrying bows (3) are, in addition, bent at right angles out of the plane of the carrying frame (1).
Carrier frame according to one or several of the preceding claims, characterized in that guides (11) are fastened on the cross members (2).

The present invention relates to a width-adjustable carrier frame usable in household appliances, particularly in cooking and baking ovens, for receiving and supporting a grilling rack, a tray, a dish, a cooking or baking sheet, or the like.
Width-adjustable frying or grilling racks are known (German Patent Document DE-GM 89 15 074), in the case of which a certain width adjustment can be fixed by means of locking devices.
This means that the change of the width of the frying or grilling rack can only be in steps.
Embodiments of the invention are illustrated in the attached drawings and will be described in detail in the following.
FIG. 1 is a perspective view of a carrier frame according to the invention;
FIG. 2 is a partial sectional view of an end area of a cross member of the carrier frame according to FIG. 1;
In FIG. 1, a carrier frame as a whole has the reference number 1 and is intended to be used in household appliances, particularly in cooking and baking ovens, and is provided for receiving and supporting a rack, such as a grilling rack, a tray, a dish, a cooking or baking sheet, or the like.
The carrier frame 1 consists essentially of two cross members 2 with at least tube-type front-side end areas as well as of two approximately U-shaped carrying bows 3. The free ends 3a of the carrying bows 3 project into the front-side ends of the cross members 2 so that the carrier frame 1 is closed in itself.
In the embodiment according to FIGS. 1 and 2, the front-side ends 3a of one carrying bow 3 are fixedly connected with the cross members 2, while the front-side ends 3a of the other carrying bow 3 are equipped with an external thread 3b. On this external thread 3b, one threaded nut 4 respectively is arranged which is freely rotatable with respect to the cross member 2 but is axially firmly connected with the latter.
