Description

Arrangement with a rail extraction device and a cooking appliance component and cooking appliance with such an arrangement

The invention relates to an arrangement with a Gargerätebauteil and a

Rail extension device for a food support. The rail extraction device comprises a first rail, which has a fastening device for fastening the rail extraction device to the cooking appliance component. The

Rail extension device comprises a second rail, which is designed to receive the food support, wherein the rails are movable relative to each other. The fastening device comprises a spring element which forms a resilient stop for the first rail on the cooking appliance component and by the spring element a damped relative movement of the rail extraction device to Gargerätebauteil in the relative direction of movement of the two rails to each other in the attached state is feasible. The relative movement is limited between a basic position and a removal position. Furthermore, the invention also relates to a cooking appliance with such an arrangement.

Such an arrangement is known for example from DE 102015206596 A1.

However, such arrangements have the following disadvantage. To release the

Rail extraction device from Gargerätebauteil the user intuitively pushes against the front end of the second rail, instead of pressing against the front end of the first rail. This is due to the fact that it faces the front end of the second rail closer and the flat end portion of the second rail

mistakenly suggested an actuating surface. Due to the stop element, which is the relative movement of the rail extraction device relative to

Gargerätebauteil limited to a defined path of movement to prevent inadvertent release of the assembly of Gargerätebauteil, the movement path is smaller than a release path for releasing the fastening device required by the Gargerätebauteil. Thus, the user action does not lead to the desired release of the

Rail expansion device. This effect is reinforced in rail extension devices with a downwardly projecting end cap at the front end of the second rail, which covers the front end of the first rail. Here, the area required for the release is hidden and therefore not to use.

It is an object of the present invention to provide an arrangement and a cooking appliance, which or which has a unique actuating surface for releasing the rail extraction device from the cooking appliance component.

This object is achieved by an arrangement and a cooking appliance according to the independent claims.

An inventive arrangement comprises a Gargerätebauteil and a

Rail extension device for a food support. The rail extraction device comprises a first rail, which has a fastening device for fastening the rail extraction device to the cooking appliance component. This first rail is thus in particular the so-called fixed rail. The rail extraction device also includes a second rail, which is designed to receive the food support. The rails are movable relative to each other, so that the second rail is in particular the running rail. The fastening device has a

Spring element which forms a resilient stop for the first rail on the cooking appliance component. By the spring element is a damped relative movement of the rail extraction device relative to the cooking appliance component in the

Relative movement direction of the two rails to each other in the attached state of the rail extraction device on the cooking appliance component feasible. Thus, by this configuration, even in the mounted state of the rail extraction device on Gargerätebauteil in a specific direction, namely in the direction in which the first rail can move relative to the second rail, a

Relative movement of the second rail and thus the entire

Rail extension device relative to the cooking appliance component allows. These

Relative movement is limited between a basic position and a removal position, wherein the basic position in the direction of force of the spring element, preferably against a direction of insertion in a first direction and the removal position against the Force direction of the spring element, preferably limited in the direction of insertion against the first direction.

It is proposed that an operating element for releasing the fastening device from the cooking appliance component is arranged on the first rail. Under a

Operating element is to be understood in particular a component or section which acts directly or indirectly on the first rail and is operatively connected therewith, that upon actuation of the operating element a relative movement of the first rail from the basic position to the removal position and a release of the entire rail extraction device caused by Gargerätebauteil.

Preferably, the operating element has an actuating surface. Under one

Actuating surface should be understood in particular a user-facing surface, which is adapted to receive a required for releasing the rail extraction device from Gargerätebauteil operating force of the user to the control. The actuating surface preferably has a size between 1 cm ² and 4 cm ² .

Preferably, an actuating marking is arranged on the actuating surface. An actuating designation should in particular be understood to mean an identification which unambiguously indicates to the user the actuating surface by means of which the rail extraction device is to be detached from the cooking appliance component. Preferably, the actuation marking is an embossment which is applied to the actuation surface. This embossment is preferably flat and / or flat. A particularly simple manufacturing process is created when the embossing of the actuation marking in the same manufacturing step as the shaping or design of the

Actuating surface is introduced. An advantage of this design is that separate steps can be saved. An embossed actuation mark is particularly simple, durable, easy to read and easy to clean. Alternatively, the marking of the actuating surface by means of a printing, engraving or gluing takes place. Preferably, the actuation identifier is a juxtaposition and / or mixture of letters, numbers, symbols or logos. A particularly good one

Labeling arises when it is a label, that is, a sequence of letters, which in their composition expresses a word which the user causes the operating element in his, to release the

Rail extraction device to be operated by Gargerätebauteil direction. Possible labels are therefore "push", "push", "unlock" or "removal", and their translation into other languages.

Preferably, the operating element is arranged on a cooking chamber wall facing side of the first rail. A particularly easily accessible position of the operating element arises when the operating element is arranged on the side wall of the first rail, on the front, the user-facing portion of the first rail. This space between the rail extraction device and the cooking chamber wall, on the one hand in the middle and rear area for the cooking appliance component in an embodiment of

Side grille has needed and thus offers in the front area for reasons of space. In addition, this area is particularly easy to reach for the user. A particularly visually appealing and functional arrangement arises when the operating element and the front end of the second rail lie on a common vertical plane.

According to a variant, the operating element is arranged on the first rail, in particular on an end face of the first rail facing the user. In this case, the operating element is formed from a separate component or from a component necessary for the first rail.

Preferably, the fastening device has a clip-like element, wherein a portion of the clip-like element forms the operating element. For fastening the rail extension device to the cooking appliance component, the first rail has a fastening device. This fastening device matured by means of a clamp-like element in the front, the user-facing portion of the first rail to a vertical rod of the cooking appliance component. A structurally particularly simple structure arises when the operating element is formed from an additional portion of the clip-like element.

Preferably, the second rail on a stop element, which is designed such that the attenuated by the spring element relative movement of the rail extraction device relative to the cooking appliance component to a defined

Movement path is limited. This movement path is smaller than one for releasing the Fastening device required by the Gargerätebauteil release path. By the stopper element thus also a Entriegelungssperrvorrichtung is formed. Even if the rail extension device is displaced in the direction of the direction of relative movement to the cooking appliance component in the mounted state, this can maximally take place until the second rail abuts with its stop element on the cooking appliance component. Since the positioning and dimensioning of the stop element is chosen in particular so that before an unwanted release of the entire

Rail extension device of the Gargerätebauteil the attacks on the

Gargerätebauteil done by the stop element is thus also in this

Motion scenario of the rail extraction device prevents unwanted loosening of the cooking appliance component. It is preferably provided that the stop element is arranged projecting upwards on the second rail. Since a particularly advantageous mechanical interaction with respect to the attacks on the cooking appliance component is achieved here, on the other hand, the loading of the second rail with the food support is not hindered, this positional arrangement and extension is advantageous.

Preferably, the cooking appliance component has a side rail. A side rail should in particular be understood to mean a structure which is composed of essentially horizontally and vertically arranged metal rods and fixed to one another by means of welding processes. Alternative cooking appliance components such as frames or mounting walls are possible.

Furthermore, the invention also relates to a cooking appliance with an arrangement according to the invention or an advantageous embodiment thereof. In particular, the cooking appliance comprises a receiving space in the form of a cooking space in which food can be prepared. This cooking chamber is limited in particular by walls of a muffle, which also has vertical side walls. At the opposite vertical

Side walls are preferably each Gargerätebauteile and

Rail extension devices arranged, which are arranged in pairs at the same height, so that in this regard on specific levels, the food support can be applied. Further features of the invention will become apparent from the figures and the description of the figures. The features and feature combinations mentioned above in the description as well as the features and feature combinations mentioned below in the description of the figures and / or shown alone in the figures are not only in the respectively indicated combination, but also in others

Combinations or alone, without departing from the scope of the invention. Embodiments of the invention are therefore also to be considered as encompassed and disclosed, which are not explicitly shown and explained in the schematic figures, but which emerge and can be produced by separated combinations of features from the embodiments explained. Showing:

cooking appliance according to the invention with an embodiment of an inventive arrangement;

Fig. 2 is a perspective view of a first embodiment of a

Rail extraction device of an arrangement;

Fig. 4 is a perspective view of an embodiment of a clip-like element with operating element.

In the figures, the same or functionally identical elements with the same

Provided with reference numerals.

In Fig. 1, a cooking appliance 1 is shown in a perspective view, which may be formed for example as a baking oven. The cooking appliance 1 comprises a cooking chamber 2, which is bounded by walls of a muffle 3. The muffle 3 comprises two opposite vertical walls 4 and 5. At the front, the muffle 3 has a

Loading opening, through which food and / or preparation vessels can be introduced into the cooking chamber 2. The loading opening can be closed by a door, not shown. The cooking appliance 1 includes in position and number only by way of example also cooking zones 6,

7, 8 and 9, but this does not have. Furthermore, the cooking appliance 1 also includes in position and design merely exemplified one

Operating device 10 with a display unit 1 1 and controls 12 and 13th

As shown in the illustration according to FIG. 1, a device or an arrangement 14 or 15 is respectively positioned on the opposite walls 4 and 5. The arrangement 14, which is formed equal to the arrangement 15, is explained in more representative of the two arrangements 14 and 15 on. The assembly 14 comprises a cooking appliance component 16, which also represents an adapter unit. The

Gargerätebauteil 16 is non-destructively detachable attachable to the wall 4. However, it can also be provided that an integral embodiment is provided. The

Gargerätebauteil 16 is formed in the embodiment as a support frame and designed as Einhängegitter. The cooking appliance component 16 is for receiving a

Rail extension device 17 is formed. The arrangement 14 is provided for receiving a food support, not shown, such as a grid or a baking tray or a fat pan, said food support then on the

Rail extension device 17 can be positioned.

As can also be seen in the illustration according to FIG. 1, the cooking appliance component 16 comprises a vertical vertical support bar 18 viewed in the depth direction of the cooking appliance 1 and a rear vertical carrier bar 19 arranged parallel thereto and at a distance from each other. The supporting frame or the cooking appliance component 16 is complete in the exemplary embodiment built from rods. With these already mentioned vertical support bars 18 and 19 guide rods are mutually connected. The guide rods, of which by way of example the guide rods 20a and 20b are marked, in pairs form a respective insertion level, on which then the food support can be inserted. These guide rods 20a and 20b are arranged parallel and spaced from each other. A corresponding embodiment is in the

opposite arrangement 15 is provided.

The assembly 14 may include a rail extraction device 17, as shown by way of example in FIG. 2. In the perspective shown in Fig. 2 it is provided that the rail extraction device 17, which is a telescopic extension, a first rail 21st has, which is designed to attach the entire rail extraction device 17 to the cooking appliance component 16. For this purpose, this first rail 21, which may also be a fixed rail, comprises the fastening device 22, which has clip-like elements 23. These clamp-like elements 23 engage in the mounted state, the support rods 18 and 19th

The rail extraction device 17 further comprises a second rail 24 which is movably disposed on the first rail 21. The second rail 24 may also be referred to as a running rail and is in the mounted state in the cooking chamber 2 in the direction of the longitudinal axis of the rail extraction device 17 and thus in the depth direction of the cooking device 1 displaced.

The already mentioned fastening device 22 comprises at the rear

Mounting bracket or the rear fastening element 23rd

in particular on the inside, a spring element 25. This spring element 25 contacted in the mounted state of the rail extraction device 17 of this cooking appliance component 16, in particular a lower guide rod 20b.

Starting from a basic mounting position, then the entire

Rail extension device 17 relative to the cooking appliance component 16 in the at

Gargerätebauteil 16 mounted state in a straight linear movement in the depth direction of the cooking device 1 are moved backwards to the rear. This will then become one

Relative movement performed in this relative direction of movement. However, this relative movement, which is then damped by the spring element 25, only possible via a specifically defined in the depth direction of the cooking appliances and thus in the direction of insertion of the second rail 24 dimensioned movement path. This path of movement is limited. This movement path is smaller than one for releasing the

Fastening device 22 required by the Gargerätebauteil release path. This means that a shift in the whole

Rail extension device 17 in the horizontal direction to the rear and thus in the depth direction of the cooking appliance 1 can only be so far as long as the

Fixing elements 23 can not solve or decouple from the support rods 18 and 19 by their clip-like shape. This movement path is limited by the arrangement and dimensioning of the stop element 28. By this construction it is possible that even with relatively powerful

Inserting the second rail 24 a then over the initial position then attenuated relative movement of the entire rail extraction device 17 for

Gargerätebauteil 16 is possible and thus a certain compensating movement can be performed dampening, so that an undesirably hard impact and an abrupt stop in the normal position is prevented. However, if such a powerful insertion of the second rail 24 is completed, in which then this maximum movement path, which is then damped, is insufficient, so occurs to avoid unwanted loosening of the entire rail extraction device 17 of the cooking appliance component 16, an abrupt stopping this damped relative movement by this stop member 26 abuts the guide rod 20b.

FIG. 3 shows in a perspective view the front end of a rail extension device 17 facing the user. The rail extraction device 17 has a first rail 21 and a second rail 24. In order to limit the above-described movement path, the second rail 24 has the stop element 26. At the, the wall 4 of the cooking chamber 2 facing side of the first rail 21, the bracket-like elements 23 is attached. At the front end of the second rail, a cap 27 is attached, which in this embodiment of the

Rail extension device 17 covers both the end face of the second rail 24 and the end face of the first rail 21. At the, the wall 4 of the cooking chamber 2 facing side of the first rail 21, the control element 28 is arranged. The operating element 28 has an actuating surface 29. For clear identification of the actuating surface 29, this has an actuation marking 30. By the actuation marking 30, the user receives a clear indication of the most suitable for releasing the rail extraction device actuating surface 29. The control element 28 shown in the embodiment is in one piece from the

formed bracket-like element 23 and secured thereto by means of spot welds on the first 21.

Presses the user to release the rail extraction device 17 against the

Actuating surface 29, the force applied to the first rail 21 and the bracket-like element 23 of the fastening device 22 transmits and acts against the Spring force of the spring element 20. This shifts the

Rail extension device 17 from the basic position into the removal position, in which the bracket-like element 23, the rail extraction device 17 is free and the user can solve this from the cooking appliance component 16. In contrast, if the user presses against the cover cap 27 or another component of the second rail 24, the force also transfers to the first rail 21 in the retracted state and a relative movement occurs, which however is limited by the stop element 26 at an early stage that the

Rail extension device 17 is released.

Figure 4 shows the bracket-like element 23 of the fastening device 22 in a perspective view. At a portion of the bracket-like element 23, the control element 28 connects with its actuating surface 29. To mark the actuating surface 29, an actuation marking 30 is embossed in the actuating surface 29. To give the user a clear indication of the operation and

Force direction was selected as actuation label 30, the word "PUSH".

It will be apparent to those skilled in the art that the invention is not limited to that shown

Embodiment is limited, but that a variety of variants and modifications are also included.
