DESCRIPTION

Retention device for a housing installation for a support of cooking product in a cooking apparatus as well as arrangement with such a retention device

The invention relates to a retention device for a housing installation for housing for a cooking product support in a cooking appliance, with a first and a second support bar, which are arranged vertically. Moreover, the invention relates to an arrangement with a retention device of this type and with a housing installation. In addition, the invention also relates to a cooking appliance with a retention device of this type and / or with such an arrangement.

It is known that in a cooking space of a baking oven the retention devices are configured as retention grids, which are installed on vertical side walls of a muffle, which delimits the cooking space. They can be arranged in the context theref in a non-removable way or in a non-destructive removable way. These retention grids are used to accommodate other components, such as a rail extraction system, such as a telescopic rail. A grid of cooking product can be placed on this telescopic rail, such as a grid grill, a fat pan or a cooking plate. In the known retention grids it is provided that two support bars are configured, one being arranged as a front support bar and one as a rear support bar with respect to the bottom of the cooking space. Between these support bars, horizontally oriented retention bars extend, which are positioned in pairs with each other and at a certain mutual vertical distance, so that an insertion plane for a housing installation is formed between two horizontal bars of this type. or a support of cooking product. A similarly configured retention device is arranged on the opposite vertical side wall of the flask.

In the known retention devices it is currently provided that these can be fixed directly through corresponding bush suspensions in the muffle wall. The number of caps is in this case relatively high. Furthermore, the fixing of a housing installation in such a retention device is often relatively complex and is limited with respect to the stable mechanical fixing support.

Document DE 103 38 158 A1 publishes a retention device for an insertion element.

EP 1 344 984 A2 publishes a lane of an extraction system especially of telescopic type for supports of cooking products of a baking oven and an extraction system.

Document DE 20 2008 000 887 U1 publishes a mounting system.

The purpose of the present invention is to create a retention device as well as an arrangement with a retention device of this type as well as a cooking apparatus, with which the fixation of a housing installation in the retention device is improved.

This task is solved by means of a retention device and an arrangement according to the independent claims.

The retention device according to the invention for a housing installation, which is configured for housing a cooking product support, comprises a first vertical support bar and a second vertical support bar. The support bars are arranged especially spaced apart and parallel to each other. In the first support bar, a first housing element is configured for coupling the housing installation on a horizontal foreground. In the second support bar, a second housing element is configured for coupling the housing installation on the first horizontal plane, so that the second housing element is configured differently from the first housing element. Through this configuration, an easier-to-use placement of the housing installation in the retention device is achieved and that improves the mechanically stable fixation.

Through the especially specific differences in the shape of the housing elements, the setting scenario for the installation of accommodation for a user is facilitated and is possible more quickly.

It is envisaged that the second housing element is configured as a pin, in particular as a horizontally extending pin, which is fixed on a support bar,

It is also provided that the first housing element is two horizontal pins arranged parallel and distant from each other and that the second housing element is a horizontal pin, in particular a pin, which is arranged in its height position between the two pins that form The first element of accommodation. In this way it is possible to minimize manufacturing time and in this way an embodiment is possible

very economical

This widening has a housing block, which rises on the widened side from this widening on an enveloping surface of the widening. In this way, not only a simple conformation and flexion of the support bar is configured as such, but this support bar is then configured again specifically to the shape in the area of the widening through the housing block. Through a housing block of this type, the joining of the housing installation with respect to a mechanically stable positioning and fixing support is favored.

Preferably, it is provided that the first housing element is configured in a C-shape or in a U-shape. It may be configured as an eyelet, which is arranged leading to the support bar. It can also be provided that the first housing element is formed by two pins, which are arranged horizontally and parallel to each other and spaced apart from each other, and both extend in particular linearly.

Preferably, it is provided that the first housing element is configured as a C-shaped stamp on the first support bar. The housing element is configured integrated in this way in the support bar, so that a very material saving configuration is achieved here.

In addition, the time for manufacturing the retention device is minimized. The C-shaped printing is advantageous with respect to its specification of the form, since in this way the accommodation of the housing installation is facilitated and an unwanted vertical slipping of the housing installation is prevented. In addition, through this configuration of the housing element, the primary coupling of the housing installation can be performed very easily and can also be recognized very easily by the user.

Last but not least, through a conformation of this type of the first housing element, a certain possibility of horizontal articulation of the housing installation already coupled with relation to the retention device is possible, without vertical slipping. In this way, the following fixation of the housing device on the second support bar is much easier.

Preferably, it is provided that the first housing element and / or the second housing element is configured in a vertical plane, in which the two support bars extend. The housing elements are thus arranged with a flat structure in the retention device. In this way, the coupling of the housing installation can also be carried out in a particularly simple and appropriate way for a user. Through this exposed position and orientation of the first housing element, the other positioning and coupling of the housing installation in the retention device can also be configured in a very easy way for the user. In particular, in the context, connection elements can also be arranged and configured in the housing installation, which are intended for coupling in the retention device, in particular in the housing elements, also in such a way that they can be carried out very compact and, on the other hand, do not prevent or impair the functionality of the accommodation installation precisely in configurations such as rail extraction systems.

In this way, it can be provided that the first housing element is configured as an eyelet and extends in the same plane as the support bars. However, another embodiment of the housing element may also be provided, for example a stamping.

Preferably, it is provided that the first housing element has an inner side, which is formed by a cover side, a central side that connects at a first angle and a bottom side that is connected there again at a second angle . This results in a particularly advantageous support structure that favors the aforementioned advantages during the coupling and retention of the housing installation.

It is especially advantageous if the first angle is between 70 ° and 110 °, in particular between 85 ° and 95 °. Preferably, in this way the cover side is essentially arranged at an angle of 90 ° with respect to the central side. In this way a corresponding stable stop is formed upwards, so that the housing installation is held upwards and does not present any play in this respect.

Preferably, additionally or in place it is provided that the second angle has between 70 ° and 110 °, in particular> 90 °. Especially when the angle of> 90 °, an inclination oriented below this bottom wall results, so that a certain easy introduction of the housing installation in this second housing element results and thus is formed, so to speak , from the bottom wall a certain funnel-shaped housing structure. The introduction is essentially facilitated in this way, since precisely at the beginning of the housing element on the inner side there is no exact adjusted housing of the housing installation or of its connecting element. In this way a certain vertical game is still present here. This prevents interlocking or unwanted extension during coupling.

Preferably, it is provided that a wrapping surface of the first housing element is configured outside the inner corner free side. The conformation of the support bar specially configured as a round bar is therefore configured correspondingly in the area of the first housing element and that area of the support bar, which forms the first housing element, is not configured , therefore, thicker than this first housing element. The contour or the surrounding surface are also formed and sized accordingly. Preferably, however, it is provided that the cover side and / or the central side and / or the bottom side of the inner side these first housing elements are configured as surface or flat surfaces. Through a specification of the shape of this type, the advantages mentioned above with respect to coupling, housing and also the retention of the joint element of the housing installation can be especially favored. The housing element is flattened in this way, as it were, in some way on the inner side through these flat surface configurations and the cross section is configured in this area with a smaller surface than the cross section of the bar. support outside the housing element.

In this way it can be provided that a first and a second housing elements extend in the same plane as the support bars. For example, this is then advantageous in a first housing element configured as a buttonhole and in a second housing element configured as a pin, which are then preferably arranged directed towards each other on the support bars. Fixing and removing a housing installation is then very easy for the user.

It is preferably provided that the second housing element is a conformation configured as an extension in the second support bar. Also here a specific printing can be provided, which is different, however, from the first housing element. Preferably, then the extension of the second housing element is oriented in a vertical plane, which is inclined with respect to the vertical plane of the support bars.

Preferably, it is provided that the housing block has an angular shape, in particular square and that the enclosure surface is specified accordingly. In this way, as large as possible support surfaces can be achieved in the union with a joint element of the housing installation and again favoring the advantages mentioned above.

Preferably, it is envisaged that the enveloping surface has two longitudinal sides, which are configured flat. In particular they are also oriented parallel to each other and are configured in the direction of the longitudinal axis of the support bar. In particular, the large surface support can be achieved in this way during the rear engagement of a connecting element and the mechanically stable positioning of the housing installation in the retention device.

The enveloping surface also has two narrower horizontal sides, which then pass to the longitudinal sides and form the square configuration of the housing block.

Preferably, it is provided that the longitudinal sides are disposed inwardly facing the enveloping surface of the widening. The housing block is thus narrower than the remaining widening, thereby improving the advantages mentioned above. Preferably, this housing block is achieved through a specific crushing of the widening.

Preferably, the housing block has an arched and corner-free roof surface. Through this configuration, unwanted corners and corners can be avoided, so that a crash and unwanted scratch and damage to the housing installation are prevented.

Preferably, it is envisaged that the support bars are joined with joining bars to form a coherent frame, in particular square. In this way, a single-piece retention grid is preferably formed, which is formed only by the two vertical bars and the two horizontal bars.

It is preferred that the retention device can be fixed on several, in particular on two pieces of union in caps in a vertical wall of the muffle, which delimits a cooking space.

A first housing element and a second housing element are arranged at the same horizontal height on the two support bars, so that through these two housing elements a housing plane is formed for a housing installation. In particular, several first housing elements arranged one below the other and several second housing elements arranged one below the other can be arranged on the vertical support bars, so that several corresponding housing planes are configured.

Preferably, the joining elements are configured in the housing installation as a single flange, which then elastically fit into the respective housing elements or engage behind them.

The placement of a housing installation is greatly simplified in this way.

Since the flat horizontal sides are also configured and formed correspondingly in the housing block, in an alternative configuration of a housing installation the joint element can also be provided for the complete horizontal limitation, so that this joint element It is then formed, so to speak, in the form of a comb or in the form of a C in the cross-section and embraces, as it were, joint element on these two horizontal sides.

Moreover, the invention relates to an arrangement for a cooking appliance with a retention device in accordance with the invention or an advantageous configuration thereof, and with at least one housing installation. The housing installation may be a rail extraction system, for example a telescopic rail of at least two tracks. However, the housing installation may, for example, also be a grid of another type or the like.

Moreover, the invention relates to a cooking appliance with a cooking space, which is delimited by means of walls of a muffle, a retention device and / or an arrangement can be fixed in a vertical side wall of the muffle in the inner side directed towards the cooking space.

In Fig. 1, a cooking appliance 1 configured as a cooking oven is shown in an enlarged perspective representation. The cooking apparatus 1 comprises a cooking space 2, which is delimited by walls of a muffle 3. The muffle 3 comprises in this case a first vertical side wall 4 and a second vertical side wall 5. In addition, a wall is still provided in the background, a cover wall and a back wall, which are not provided, however, in detail with reference signs.

The cooking apparatus 1 comprises in a position and number only exemplary cooking zones 6, 7, 8 and 9. In addition, in the same way in position and configuration, a control device 10 is provided, which comprises a representation unit 11 and control elements 12 and 13.

As can be recognized from the representation in Figure 1, the cooking apparatus 1 comprises an arrangement 14, which has a retention device 16 and a housing installation 17. The arrangement 14 is fixed on the vertical side wall 4. Similarly, a corresponding arrangement 15 is arranged on the vertical side wall 5.

The arrangement 15 with the retaining device 16 is explained in detail below. An example of embodiment of the retaining device 16 is shown for this purpose. This presents a first vertical support bar, in particular rear 18 and a second vertical support bar 19 in particular front. With respect to the orientation in the vertical side wall 4, the first support bar 18 is thus arranged further away from the loading opening than the second support bar 19 arranged parallel to the first support bar 18, and is located , therefore, further away from the rear wall of the muffle 3. The two support bars 18 and 19 are connected at their upper and lower ends with horizontal tie rods 20 and 21, so that a rectangular frame is formed. The retention device 16 is configured in a single piece of wire. As can be recognized, in the first support bar 18 several first housing elements 22 are configured.

In addition, several second housing elements 23 are configured in the second support bar 19. It can be recognized that, respectively, a first housing element 22 and a second housing element 23 are arranged at the same height level with respect to the longitudinal axis of the support bars 18 and 19 and, therefore, also with respect to their height orientation. A first housing element 22 and a second housing element 23 thus form a housing plane for a housing installation 17. The housing installation 17 may be, for example, a system of extraction rails or another retention lane. .

The horizontal tie rods 20 and 21 are oriented linearly and parallel to each other. As can be recognized from the representation in Figure 2, the horizontal tie rods 20 and 21 are not arranged in a plane, in which the two vertical support rods 18 and 19 extend. At the upper and lower ends of the vertical support bars 18 and 19, there are configured connecting pieces oriented inclined forward, so that the horizontal union bars 20 and 21 are moved forward in front of the support bars 18 and 19, which means in the arrangement in the cooking space 2 that the horizontal joint bars 20 and 21 are positioned closer in the direction of the cooking space 2 than the support bars 18 and 19.

In the representation according to figure 2 it can also be recognized that in the first support bar 18 a fixing element 24 is arranged and in the second support bar 19 another fixing element 25 is arranged, which can be configured, for example, of the pin type. With these fixing elements 24 and 25, the retention device 16, which is configured as a retention frame, can be fixed in cages, which are configured in the side wall 5. In the embodiment example, only these two fixing elements are provided 24 and 25, which are preferably configured at approximately mid-height of the support bars 18 and 19.

In figure 3, a first housing element 22 is shown in an enlarged representation, which is configured as stamping on the support bar 18, which is otherwise linear. This first housing element 22 is configured in a C-shape and is configured in its different conformation and configuration from the first housing element 23. The first housing element 22 has sections in a wrap-around surface 26 free of corners and, therefore, rounded. On an inner side 27, this enveloping surface is not continuously arched, but is formed by three flat or plate-shaped surfaces that connect with each other. The inner side 27 has for this purpose a cover side 28, which is closer to the upper horizontal bar 20 than a middle side 29, and has a bottom side 30 which is connected therein.

Through this flattened inner side 27 or in the form of a plate, an extraordinarily easy for the user and mechanically stable housing of a connecting element of a housing installation 17 is achieved. It is especially preferred that an angle to between the cover side 28 and the central side 29 have 90 °. Furthermore, it is especially advantageous if an angle p between the central side 29 and the bottom side 30 is> 90 °, preferably up to 110 °, thereby facilitating the introduction of the connecting element in this housing element 22 in shape

of C.

Furthermore, it should be mentioned that the first housing element 22 is oriented and arranged in the support bar 18 such that a horizontal plane is oriented through the housing element 22 in a plane, in which they extend at the same time the two support pieces 18 and 19. The longitudinal plane, which extends through the housing element 22, is in figure 3 the plane of the figure.

An enlarged fragment of the retention device 16 in the area of a second housing element 23 is shown in a perspective representation. It can be recognized that the second housing element 23 is formed in the same way by a conformation or either a stamping of the second support bar 19. In this way a widening 31 is generated. On the outer side of the widening 31 and, therefore, so to speak, on the outer maximum in the form of a widening clamp 31 is formed a housing block 32. The housing block 32 extends over an enveloping surface 33 of the widening 31 raised outwardly or above. The housing block 32 is angularly formed, in particular square and thus has, as it were, a square enveloping surface. To this end, two longitudinal sides 34 and 35 are configured, which are oriented parallel to each other and are oriented in the direction of the longitudinal axis A of the support bar 19 or are oriented parallel thereto. Moreover, a longitudinal axis B of the first support bar 18 is also shown in Figure 2, which extends parallel to the A axis.

The housing block 32 further comprises two horizontal sides 36 and 37, which lead to the longitudinal sides 34 and 35. As can be recognized from the representation in Figure 4, the housing block 32 comprises, at the same time. , the roof surface or arched roof surface free of corners.

Furthermore, it can be recognized that the longitudinal sides 34 and 35 are displaced in front of the adjacent enclosure surface 33, so that the housing block 32 is narrower in this area than the rest of the widening 31.

A second housing element 23 is formed in a single piece from the support bar 19, because, on the one hand, a conformation is carried out, so that the basic widening 31 is generated. In a subsequent crushing process it is formed then the housing block 32 from this widening 31.

The housing element 23 is configured in a plane E, which is in the plane, in which the support bars 18 and 19 extend.

An example of embodiment of arrangement 14 is shown in FIG. 5, in which the retention device 16 according to FIGS. 2 to 4 is partially shown and fixed therein and to a housing installation 17 in the form of an extraction system. of lanes

The representation in figure 5 shows, unlike the configuration according to figure 2, the retention device 16 in the arrangement 14, while in figure 2 the retention device 16 of the arrangement 15 is shown.

As can be recognized from the representation in figure 6, which shows an enlarged fragment of the embodiment in figure 5 in the area of the first rear housing element 22, the union element 39 configured in a U-shape and the housing element 22 rolls in the C-shaped cavity, in particular in the area of this central rib with the inner side 29.

An enlarged perspective view of the embodiment in Figure 5 is shown in Figure 7 in the area of the second front housing element 23.

During assembly, the joint element 39 is first inserted into the first rear housing element 22 and then pivoted through a vertical downward movement of the housing installation 17, so that the other joint element 40 passes from above on the housing block 22 and then hugs it accordingly. The connecting element 40 comprises an upper stop 41, so that a wide slide down from the housing installation 17 is prevented.

In figure 8 the arrangement 14 is shown in a top plan view.

Figure 9 shows a representation of the horizontal section of the embodiment in Figure 8 in the area of the connecting element 39. The flat or flattened central side 29 can be recognized.

In addition, a representation of a horizontal section of the embodiment in Figure 8 in the area of the connecting element 40 is shown in Figure 10.

In figure 11, another example of embodiment of an arrangement 15 is shown in perspective representation. In this, unlike the configuration of the example of embodiment explained so far, it is provided that the

second front union element 40 is configured in the same way in a C-shape or U-shaped, but in relation to the orientation in this way it is rotated about 90 ° with respect to the orientation of the union element 39 of the same C-shaped or U-shaped way. The second joint element 40 does not laterally embrace the housing block 32, but from above and below, so that the union element 40 is in contact with the sides horizontal 36 and 37 in the mounted state.

An enlarged representation from the area of this second joint element 40 in the assembled state of the housing installation l7 in the retention device 16 is shown in Figure 12.

In figure 13, another embodiment of a retaining device 16 is shown in perspective representation. Unlike the embodiment in Figure 2, here the first housing element 22 is configured as a U-shaped eyelet or C-shaped, which is arranged at the support bar 18. The support bar 18 extends fully between the two free ends of the eyelet, so that the first housing element 22 is closed, so to speak, through of the support bar 18 behind. A buttonhole has two parallel horizontal eyelet arms 22a and 22b and a vertical eyelet arm 22c connecting these eyelet arms 22a and 22b.

The first housing elements 22 extend in a vertical plane, corresponding to the plane, in which the support bars 18 and 19 extend. The first housing elements 22 are also arranged directed towards the support bar 19 in the bar. of support 18.

The second housing elements 23 are configured as pins, which extend horizontally and extend in the same way in the plane of the support bars 18 and 19. They are arranged in the support bar 19 directed towards the support bar 18.

To assemble a housing installation 17 in the retaining device 16, a connecting element of the housing installation 17 is threaded first in the eyelet and elastically fits into the support bar 18. Then through A vertical articulation movement places a second connecting element from above on the second housing element 23 and is fixed therefrom, for example by means of a simple suspension or elastic fit, etc.

Also the pins according to the housing elements 23 are configured in the plane of the support bars 18 and 19.

It can also be provided that the housing elements 22 are arranged in the second support bar 23 and the housing elements 22 are arranged in the support bar 18.

In figure 14 another example of embodiment of a retention device 16 is shown in front view. Here the first housing element 22 is configured by two pins, which are configured linearly and extend horizontally. The two pins are arranged parallel and spaced apart from each other. The second housing element 23 is configured as a single pin, which is arranged in the same way horizontally. Furthermore, it is preferably provided that the pin that forms the second housing element 23, considered in its height position and, therefore, in the direction of the longitudinal extension of the support bars 18 and 19, is arranged between the pins of a first housing element 22 associated with the formation of a housing plane.

The embodiments in Figures 2 and 14 can also be combined into individual features, in particular with respect to the shape and orientation of the housing elements 22 and 23, to obtain new embodiments.
