The devices include, for example, two relatively slidable rails and intervening load-bearing bearing means with rolling elements for sliding movement of the rails in question. In the furniture sector, such as in kitchen furniture such devices for guiding, for example, a drawer or a food support or a baking sheet or a baking grid in ovens are in use. So-called partial extracts include a fixed rail or support rail and a pull-out rail which can be coupled to the push element. With full extensions a larger extension length is possible, for which an additional middle rail is available.

The partial or full extension is on an inner side of the wall portion such as a carcass wall of a Furniture carcass or a side wall of a kitchen appliance attached directly or as in ovens, for example via an existing on the wall portion grid structure of a baking muffle.

In particular, in kitchen equipment or ovens, the guides must meet complex requirements, for example, be heat resistant, and on the other hand be compact in design and reliable or stable on the one hand.

Purpose and advantages of the invention

The object of the present invention is to provide devices or kitchen devices mentioned in the introduction with regard to a technically and economically advantageous manner, in particular with regard to the user friendliness of the arrangement.

This object is solved by the independent claims.

The dependent claims address advantageous embodiments of the invention.

The invention is based on a device for guiding a pusher element, which can be accommodated displaceably on a wall section by means of the device, the device having a guide unit with guide rails which can be displaced relative to one another. The core of the invention is that the guide unit is connected to a receiving element of the device, which can be arranged on an inner side of the wall portion, wherein the receiving element has a projecting engagement portion which is formed for a penetration of a wall recess of the wall portion, wherein the through-reach portion accessing adjusting means are provided, with which the receiving element with attached thereto guide unit in the vertical direction is adjustable and lockable. This can be the Advantageously use guide unit, in particular without direct access in an interior, in which the device and the applied thrust element is present. In addition, it is advantageously possible to dispense with a lattice structure on the wall section, wherein the lattice structure represents an interference contour or requires a construction space on the inside of the wall section. A grid structure is also not height adjustable. This applies equally to both opposite identical wall sections in the internal volume of a baking muffle.

The adjustment of the guide unit refers to the position of the guide unit or its fixed rail on the wall portion and has nothing to do with the mobility or telescoping of the extract or the middle rail to the fixed rail.

The receiving element is part of the device for guiding the pusher element, but not part of the guide unit. The guide unit is formed in particular as a commercial guide.

The receiving element and the guide unit are fixed preferably releasably connected to each other.

Advantageously, the adjustment can be made from outside of an interior volume which can be separated from the environment of the interior of the interior area bounded by opposing vertical wall sections, for example a kitchen device such as a baking chamber of a baking oven. Advantageously, this is possible in operation at high temperatures in the oven or during cooking, without that at high temperatures in the baking muffle and thus the device this must be taken, which brings with additional cramped conditions a risk of burns for the user. With the invention, the user can work comfortably, especially during the cooking operation individually the height position of the food support in the interior of the heated Easily change baking muffle. This is particularly advantageous for longer cooking processes or when using top or bottom heat.

The receiving element is preferably flat and is supported on the inside of the wall portion. A particular flat flat side of the receiving element is used for contact with the inside of the wall portion. On the flat side of the receiving element of the punch-through section is, in particular with a projection which is slightly more than the wall thickness of the wall portion.

Preferably, the punch-through portion engages from one side of the receiving element, which is assigned to the wall portion, through the wall portion or its thickness through to the outside and may optionally protrude on an outer side of the wall portion. It is possible to access the receiving element and thus the guide unit attached thereto from outside the wall section or to move it from the outside. To adjust an established locking of the receiving element is canceled and then set up again.

The adjustment is made in particular advantageously and simultaneously for opposite guide units with a respective receiving element, wherein a common pushing element or, for example, a baking tray rests against the opposite guide units.

This means that, for example, identical guides, in particular at the same vertical height, are provided on opposite wall sections of a baking oven with a corresponding device according to the invention and are therefore similarly adjustable in height from outside or outside the wall section or outside the baking oven.

The adjustment of the receiving element with the guide unit thereon makes it possible to position and lock the guide unit in different attachment positions, which differ from one another in the vertical direction.

The receiving element also has the advantage that the guide unit for use in the present invention need not be changed compared to conventional guide units. The guide unit only has to be connected to the receiving element, which can be done, for example, according to conventional connections of guide units with a body wall by screwing or by hooking or clipping. The connection is made with the carrier rail.

Further, it is advantageous that the guide unit comprises a fixed portion to be assigned to the wall rail, wherein the receiving element is provided on the fixed rail. In particular, the receiving element is mounted attached to a vertical portion of the fixed rail. A solid rail is usually a multiple bent sheet metal material. At a z. B. upwardly free, alignable to a wall portion vertical leg, the receiving element is advantageously attachable.

The guide unit advantageously also has a drawer to assign the drawer rail and load-bearing bearing means for a sliding mounting of the drawer rail, possibly even a middle rail.

An advantageous modification of the subject invention is characterized in that at least two guide units are present on a receiving element. Thus, two or more guide units can be accommodated together on a receiving element and adjusted with this. The vertical distance of the at least two guide units remains unaffected.

On a piece of furniture or on an oven, for example, on opposite wall sections, on which two or more pusher elements such as baking trays are slidably received via respective laterally arranged guide units, with a respective receiving element on the two wall sections, ie left and right, a common and similar or identical adjustment of each two or more guide units are made.

Preferably, exactly two guide units are provided on a receiving element of a first wall section. On an opposite receiving element on a wall portion opposite the first wall portion, a corresponding receiving element is provided with exactly two guide units positioned corresponding to one another.

It is also advantageous that a plurality of guide units are present on a receiving element, which are vertically offset from each other. In the depth or in the direction that can be provided with the guide units, the pushed-together guide units lie with a front end, for example, on a common vertical or are aligned. In the longitudinal direction, the guide units are usually aligned parallel or horizontal.

The common inclusion of multiple guide units on a receiving element is particularly advantageous because in an oven regularly in several horizontally aligned planes thrust elements are to be accommodated. Each level makes it possible to receive a thrust element displaceably laterally via one guide unit each. The plurality of guide units on one side are provided on a first receiving element and the other guide units on the opposite side are provided on a second receiving element. The opposite receiving elements are accordingly preferably similar and at the same position on the respective wall section available.

Not excluded is an arrangement in which two or more guide units in the depth of the wall sections bounded by the inner volume offset from each other are preferably present on a common receiving element. The offset guide units may be at the same height or at different vertical heights.

It is further proposed that fixing means are provided for detachably fixing the device to the wall section in an adjustment position. With the fixing means, the receiving element can be locked in an adjustment or released again. The locking is preferably carried out with the help of the static loadable solid wall section. The vote of the punch-through portion and the associated wall recess is preferably such that a continuous or stepwise adjustment according to a predetermined grid in a desired height positions of the guide unit on the wall portion is possible, along the wall recess a plurality of different height positions for the receiving element and thus the guide unit possible are.

In baking ovens there is regularly a baking muffle which has side opposite walls forming the wall sections and an upper side and a bottom surface preferably made of a metal material.

In each case, then, adjacent to the opposite walls of the baking muffle, there is usually a gap adjacent to which a wall, for example, a baking oven body or a laterally available piece of furniture adjoins the outside. In the intermediate space find the adjusting or fixing advantageous place. In the lateral space connecting means for connecting the fixing means may be provided with other units such as a drive. Advantageously, the gap is thermally largely decoupled from the heated inner volume of the baking muffle. This is advantageous for the fixative.

Advantageously, the receiving element is present in an end-side longitudinal section of a fixed rail. This can be done on the receiving element a compact and material-saving connection of the guide unit.

Preferably, the guide unit is mounted alone on the receiving element on the wall portion. The end-side longitudinal section of the fixed rail preferably extends over a front partial length of the fixed rail, preferably over approximately 30 to 50% of the total length of the fixed rail.

It is also advantageous that the receiving element is designed as a flat material. For this purpose, in particular a plate-like flat material is advantageous, in particular a thin sheet.

An advantageous variant of the invention is characterized in that the receiving element has a material thickness of a few millimeters, for example, preferably 1 to 5 millimeters. In particular, the receiving element has a uniform or constant material thickness over the entire extent. The receiving element can be, for example, a quadrangular, heat-resistant and corrosion-resistant stainless steel material or lacquered sheet metal material in its basic form.

It is also proposed that a plurality of punch-through sections are present on a receiving element. In particular, these punch-through sections are identical to one another, for example offset vertically and / or horizontally. This achieves particularly good guidance and connection to the wall section and also mobility and storage. The punch-through sections are, for example, thin projecting webs, which in the direction of displacement of the pull-out rail of Guide unit are offset and which are configured in particular at the same height on an outer side of the receiving element. The punch-through sections may, for example, be material sections of the receiving element cut free on three sides and bent at an angle. The respective wall recesses in the wall section are preferably matched to the punch-through sections, so that the punch-through sections guided in the wall recesses are displaceable, for example in the manner of a sliding guide.

It is also advantageous that exactly one guide unit is present on a receiving element. This can be adjusted individually a single guide unit. On the opposite wall portion advantageously a corresponding arrangement is provided, whereby the height position of a single pusher or baking tray is similar adjustable.

In this case, a desired height positioning of the pusher within the internal volume of a baking oven can be made. The maximum adjustment distance for the receiving element results from the vertical extent of the wall recess, taking into account the height of the punch-through section.

It is further proposed that, according to an advantageous embodiment of the invention, a plurality of receiving elements are provided on a guide unit. In particular, two offset in the longitudinal direction of the guide unit receiving elements are provided. This can be advantageous, for example, for longer and possibly higher loadable guides for their support and adjustment.

Advantageously, a drive arrangement for the particular motorized adjustment of mutually assigned and arranged on opposite wall sections receiving elements is provided. The drive arrangement is such coordinated that a common, controlled or jerk-free adjustment of mutually associated receiving elements by the same distance up or down takes place, which relates to the mounted on the wall sections state. In this case, corresponding starting positions of the associated opposite receiving elements are taken as a basis, so that a thrust element in its planar extension during adjustment horizontally aligned remaining supported on the opposite receiving elements on the associated guide units. If an adjustment made with the drive assembly, both receiving elements are simultaneously adjusted identically or by a same adjustment in the same direction within the adjustment interval. The pusher moves only translational or vertical, so that, for example, in the cooking mode of a baking oven, a baking sheet without an undesirable tilting is adjustable. The food on the baking sheet can not slip and any liquid collected in a tin well can not leak. This is advantageous over an adjustment without a drive arrangement, in particular by hand, in which, for example by carelessness, the aforementioned scenarios are not excluded.

The drive arrangement preferably comprises an electric motor. With in particular exactly one electric motor, the adjustment of opposite receiving elements can be advantageous. The electric motor is preferably used to drive a movable actuator or a transmission element, for example with a belt or gear drive arrangement or with a gear or pinion or a rack, a friction wheel, and / or a belt or the like. This can be done to save space from the outside or from a respective outer side of the wall sections, the adjustment.

Furthermore, it is advantageous that the drive arrangement comprises a spindle drive. For example, can be punched out or otherwise attached to the receiving elements tabs on which a spindle nut is fixed with a through hole available. The passage opening has an internal thread which cooperates with an external thread of a reaching into the through hole of the spindle nut, in particular vertically oriented rotatable spindle. By driving the spindle with the drive unit, the spindle nut is moved vertically along the external thread of the spindle, so that a height adjustment of the receiving element is possible. By appropriate arrangements both receiving elements adjusted accordingly and thus both receiving elements with the respective guide units. About the adjustment height of the receiving element is an opening in the wall section set up.

The invention also relates to a kitchen device such as a kitchen furniture or an oven device with a device according to one of the embodiments described above.

In particular, the kitchen device is an oven with a heatable oven or baking muffle, which has at opposite lateral wall portions similar devices as explained above.

In the baking muffle, for example, two or more guide units are identically provided on both lateral wall sections on a respective height-adjustable receiving element. In addition, for example, at least one guide unit can be attached to a fixed position receiving element below and / or above it on each wall section.
