Description

The invention relates to a pull-out device for a food support with at least one rail with a sliding portion. Furthermore, the invention relates to a cooking appliance for receiving such a pull-out device.

Numerous types of pull-out devices are known from the prior art which are suitable for receiving a food carrier, such as a food carrier. a grate or a Blecheinschubelement, such as a baking tray or a baking pan are suitable. These pull-out devices differ in their function and user-friendliness.

Particularly user-friendly are pull-out devices when they lead the food support on mounted rails tilt-proof and - preferably the entire food support - lead out of the oven. A particularly simple handling of the product carrier loaded with food is made possible when the user can grip the food support in the extended state laterally to remove the food support from the extension device.

The extraction devices hitherto known from the prior art, such as e.g. Oven rib, suspension grid, normal extension or full extension, do not allow these user requirements.

In addition, food supports are known from the prior art, which have locking stop elements. In this case, the stop-stop element usually represents a downwardly formed stop element which moves on the device side to a counter-stop to stop pull-out movements.

The invention is based on the DE 102009002219 A1 , Home appliance, which shows a pull-out system that has a tilt protection for the payload carrier on the rails, which limits a gravity-induced tilting of the payload carrier to an allowable limit.

A disadvantage of this solution are the upward-facing stop contours for hitting the pull-stop, as they oppose the stackability of Garguträger and do not meet the design claim. In addition, the guide groove of the drawer system dirty in the cooking mode such that a malfunction of the rest stop and thus a violation of the norm is foreseeable.

The invention has for its object to provide a pull-out device for a food support, which fulfills a comfortable undressing the food support in compliance with all standards with respect to tilt angle and stop.

According to the invention, the object is achieved in each case by the entirety of the features of the independent claims. Further advantageous embodiments of the invention are described in the subclaims. The invention also finds application in a cooking appliance according to claim 15.

According to the invention, the pull-out device for a food support with at least one rail with a sliding section has a lateral guide element, a latching element and a holding element. The lateral guide element holds the food support transverse to the extension direction, so that the food support is guided laterally in its rest position and in the extension movement and can not slide in the lateral direction of the extension device. The latching element forms a stop on which a latching stop element of the food support can strike, thus stopping a pull-out movement of the food support, whereby unintentional pulling out of the food support is prevented over a safety-critical area. The holding element limits the tilt angle of the food support when it strikes in its extended position with its catch stop on the locking element of the extension device by the lateral holding portion of the food support is taken from the holding element.

In a basic embodiment of the invention is seen in the insertion direction, arranged after the guide element, the locking element and then the holding element. This sequence allows the food support to slide in its extension direction from a rear rest position to a front position on the extension device until the rest stop of the food support strikes the locking element, and is guided safely from the lateral guide element.

According to a variant, the extension device has a fixed rail and a running rail. In this case, the two rails are preferably designed to be latched relative to one another in such a way that the running rail and guide rail latch relative to one another in the extended or retracted state in such a way that a force has to be overcome in order to move the rails over the catch. This variant for rib recording or Einhängegitter represents an excerpt, in particular a telescopic extension, which is designed as a normal or full extension.

Preferably, the guide element is attached to the front end of the running rail in order to guide the food support with the greatest possible distance from the holding element. Preferably, the guide element is arranged substantially frontally on the running rail. The guide element may be e.g. from a sheet metal part or a free-form element, such as e.g. Die-cast or sintered part, which is attached to the running track e.g. screwed, pressed or welded.

A particularly good guidance of the food support is achieved if the guide element has a lateral guide section. This forms a kind of upstanding rib on which the food support is leaned transversely to the extension direction and leads the food support transverse to the extension direction.

In addition, the guide element may have a stop which serves as a stop in the extension direction of the stop of the food support. This additional stop gives the user the feedback that when this extract point is exceeded, the food support is free of any guidance.

Preferably, the extension device has a latching element which forms the stop for the gargutträgerseitigen detent stop to stop the food support in its extension movement. The locking element is mounted between the retaining element and the lateral guide element. This locking element may be an additional element, for example a sheet, which is applied, for example, welded, or is formed from the existing rail, for example by a stamping or embossing. Alternatively, the locking element of the rail, for example in the form of an established expression educated. Furthermore, the locking element prevents incorrect operation, since a food support inserted in the wrong direction strikes and blocks these latching elements.

According to the invention, the holding element for limiting the tilt angle of the food support is designed so that it engages around the food support laterally, whereby the lateral guidance of the food support is ensured in the rear region of the extension device. The width of the holding element is - seen in the insertion direction - limited, preferably 1 - 5 cm, do so that it surrounds the food support only in a small section, whereby the lateral gripping the food support - especially in the user-facing portion of the extension device - is not affected. The holding element may be a part of the rail or an additional element, such. B: a sheet metal part or a wire part attached to the rail, e.g. is welded. Through these designs, the holding elements pollute less and ensure the reliability of rest stop and anti-tip device. A particularly good fixation of the food support in its retracted position is achieved when the holding element has a relation to the sliding surface of the rail and arranged in the transverse direction to the extension direction paragraph, which serves as the stop arranged on the food support stop.

Preferably, the holding element forms a substantially C- or U-shaped cross-section. In this case, the opening of the C or U-shaped cross-section to the center of the food support. The base of the C-shaped cross section forms the attachment point of the retaining element to the extension device and the paragraph arranged transversely to the extension direction paragraph, which serves as a stop for the stop of the food support. The upwardly extending part of the C-shaped cross section forms the lateral guidance of the food support transversely to the extension direction. The upper portion of the C-shaped cross section forms the holding portion, which forms the contact surface for a tilting food support.

Preferably, the holding element has an insertion aid, which centers the food support in the insertion movement in the vertical direction for easier positioning. This insertion aid may be an additional element, which is formed in the transverse direction to the extension direction is substantially trapezoidal. Another Design of this introducer provides to form the insertion especially sliding and scratch-free relative to the food support.

The holding element has, viewed in its cross section, a height H between the sliding surface and the upper portion of the C-shaped cross section for determining the tilt angle. The food support tilts in its extension movement, because e.g. the center of gravity of the food support device over the front edge of the extension device device, suggests the food support on the stop surface of the holding section. The height H defines the maximum tilt angle, which is tuned to the legal standards and prevents too steep tilting of the food support. As a result, spilling over or falling out of the food from the food support is prevented.

Preferably, the distance between the holding element and the guide element is greater than half the length of the food support. The distance between the holding element and guide element is smaller than the distance of the food support between the back Gargutträgerkante and the rest stop.

In the extended position of the food support on the extension device this is completely outside the cooking chamber. This is made possible by first extending the running rail of the pull-out device and then extending the food support on the sliding section of the pull-out device until it stops at the stop.

If the food support is located on the sliding surface in a position in which the stop stop of the food support strikes the detent element, the food support is to be moved by means of a pulse of the user in the extension device over the detent stop in order to remove the food support from the extension device.

The invention solves the problem additionally with a cooking appliance having a pull-out device.

For consistent description of directions on a cooking appliance is loud Fig. 1 introduced a descriptive coordinate system. This defines in the X direction, the front of the device, go from the right to the left side of the device and in the Y direction, the insertion direction, starting from the extended state of the food support in the retracted state and in the Z direction, the height of the cooking appliance, starting from the cooking appliance bottom to Gargerätoberseite.

In Fig. 1 is shown in a perspective view of a cooking appliance 1 for preparing food, which is an oven in the embodiment. The cooking appliance 1 comprises a cooking chamber 2, which is bounded by the side walls 3 of the oven. On the front side, the cooking chamber 2 has a loading opening, which can be closed by a door 4. On the side walls 3 is ever a food support receptacle 5, which is suitable to receive food support 6, such as grates, baking trays or similar accessories. The Gargutträgeraufnahme 5 has different insertion heights, according to the embodiment Fig. 1 are formed differently. The upper slot height shows a simple Einhängegitter, the lower slot height shows a pull-out device in the form of a telescopic extension. This may be a normal or full extension. The following description of the figures relates to a rail extension system, but is also transferable from its functions to a suspension grid.

Fig. 2 shows a perspective view of the extension device 7. Such telescopic extension devices 7 essentially consist of a fixed rail 8, which is rigidly or adaptably attached to a Gargutträgeraufnahme 5 or fixed or adaptable attached to a side wall 3. This fixed rail 8 is essentially suitable by rolling or sliding body, not shown, to receive rails 9 and move in the Y direction. The length of the running rail 9 is designed essentially to the length of the food support 6, so that it abuts in the retracted state in the cooking chamber 2 at the rear stop 10, and does not protrude beyond the front end 12. The rear stop 10 is formed in this embodiment of a so-called pin. At the front end 12 of the extension device 7 is the guide member 13 which secures the food support 6 for lateral guidance in the X direction. The pullout device 7 is executed in the illustrated embodiment of a quadrilateral profile as a running rail 9, but may also be formed of so-called. C-rails. Starting from the front end 12 of the extension device 7, the latching element 14 is arranged for striking a latching stop of the food support on the sliding portion 11 in the Y direction. In the further course of the sliding portion 11 is in the Y direction, the holding element 15 for limiting a tilt angle of the food support 6. In the in Fig. 2 shown pullout device 7 are those on the left This is mirror-symmetrical to a arranged on the right side wall extension device 7 constructed. In each case two oppositely arranged on a rack level extension device 7 result in a pair of rail pairs, which together accommodate the food support 6 and stored in the Y-direction and extend extendable store. Such pull-out devices are heat-resistant, in particular pyrolysis resistant, dishwasher suitable and microwave resistant.

Fig. 3 shows in a perspective view of the detail of a guide element 13. This is arranged at the front end 12 of the track and thus forms the front end and the frontal viewing surface of the extension device 7. The guide member 13 is embossed by a non-illustrated fastener with the track rail 9. Alternatively to this embodiment, the guide member 13 can be welded to the track rail. The guide element 13 of a left-hand extension device 7 has a guide section 16 on the left-hand end as seen in the X-direction. This guide portion 16 extends in the Z direction and forms a kind of rib, which is adapted to the food support 6 suitable to perform the food support 6 in the X direction and thus transverse to the extension direction Y in the way that the food support 6 is not laterally of the running rail 9 can slide. This is particularly important because conventional extension systems at the front end 12 have a stop analogous to the rear stop 10 and the food supports thus rigidly rest on the running rail 9 and are not designed to be slippery. In addition, the guide element 13 has a stop area 17, which causes a stop of the food support in the extension direction X, starting from the sliding portion 11 of the running rail. This stop of the food support 6 at the stop area 17 conveys the user the point at which the food support leaves the sliding section 11 in the extension direction and thus is located in front of the front end 12 of the extension device 7. In addition, the stop area 17 fulfills a safety-relevant feature, since a food support 6 pushed in or turned upside down by the user stops with its stop stop in the extension direction Y at this stop. Seen from the front, the guide element 13 extends over the circumference of the running rail 9 in the direction of the side wall 3, since in the X direction, a longer stop area is formed, which serves as a stop surface of the stop stop of the food support 6.

The locking element 14 in Fig. 2 is designed as a welded-on leaflet. Alternatively, the locking element 14 can also be clicked or formed as a recess or directly from the running rail 9. In this case, the locking element 14 extends analogously to the guide member 12 over the cross section of the running rail 9 and the sliding portion 11 in the direction X addition, to provide the stop stop of the food support 6 a stop.

Fig. 4 shows the perspective view of the holding member 15. The holding member 15 consists essentially of the areas lower holding portion 18, rear holding portion 19 and upper holding portion 20. The holding member 15 with its three holding portions 18, 19, 20 results in a substantially C-shaped cross-section, whose opening points to the center of the food support. In this case, the lower holding portion 18, the holding member 15 to the running rail 9 in the direction of side wall 3, preferably analogous to the lateral offset of the guide member 13. The rear holding portion 19, which is arranged substantially perpendicular to the lower holding portion 18 extends in the Z-direction and defined the height H. The height H is adapted to the located on the extension device 7 Gargutträgern 6, depending on the standard, which dictates how large the maximum tilt angle of the food support 6 may be. The greater the height H, the higher the maximum tilt angle. The upper holding portion 20 represents the stop which opposes the food support 6 when it tilts. In addition, an insertion aid 21 is attached to the holding element 15, which should make it easier for the users to position the food support 6 on the elevator device 7. For this purpose, the insertion aid 21 has chamfers and curves. The width of the holding element 15 is adapted to the geometric conditions, taking into account the tilt angle. The lower holding portion 18, which is directed away from the running rail 9, also has the functionality of a stop for the locking element of the food support 6. In the retraction movement, the running rail 9 must first strike in its rear position before the food support 6 slides on the sliding surface 11 to the rear. Only then will the rest stop of the food support 6 be pushed over the lower holding portion 18 and gives the user the feedback that the food support 6 has arrived in its final position. In the extension movement, the lower stop 18 fixes the food support in its position and thus allows before the food support 6 moves on the sliding portion 11, the bearing rail 9 first moves from its rear to its front position on the fixed rail 8. This means that the lower holding portion 18 the food support 6 while in his fixed rigid position on the running rail until this running rail 9 has come in its extended position relative to the fixed rail. This function of the lower holding portion 18 may also be performed via an additional element on the holding element 15.

Fig. 5 shows the food support 6 in a first position. Here, the state is shown in which the food support 6 abuts the rear stop 10 of the extension device 7 and in a previous step from its rear rest position the so-called. Retracted state, was pulled into a position in which the extension rails of the extension device 7 are maximally extended , This state corresponds to the extended state of the normal extension. In this position, the food support 6 is brought by the user by this engages the food support at its front edge 22 and pulls in the Y direction. In this position, the food support is held by all four sides by resting in its rear region on the rear stops 10, is held laterally by the holding elements 15 and is held forward by the voltage applied to the holding element 15 detent stop of the food support 6 to the front , In addition, the stop area 17 forms a stop forward.

Fig. 6 shows the food support 6 in a second position in which the user has taken the food support 6 at its front edge 22 and guided by force into the front stop position. In this case, the latching element of the food support 6 has been brought over the stop of the holding element 15, so that the food support 6 could be moved on the sliding portion 11 until the stop stop of the food support 6 abuts the stop region 17. This point of the locking element 14 on the sliding portion 11 is selected so that the trailing edge 23 of the food support 6 is still detected by the holding element 15, so as to prevent the tipping of the food support 6. In this position, the user has the opportunity to grasp from the front edge 22, and the food support 6 now to grab at its lateral holding portion 24. This encompassing is particularly preferred by the user, since he can now lead the food support 6, which is usually heavily acted upon by the weight of the food, better because he can take the food support 6 closer to his seen in the Y direction focus. Thus, unintentional tilting of the food support 6 is avoided outside the guide by a pull-7.

Fig. 6 also shows the position in which the food support 6 is to be brought by the user in order to introduce this into the extension device 7. Here, the rear portion 23 of the food support 6 is placed on the sliding portion 11, and pushed in the direction Y. Once the rest stop of the food support 6 has been pushed over the stop 18 of the support member 15, the food support 6 is in its final position. In the meantime, the running rail 9 is rolled on the fixed rail in its rear end position.

Fig. 7 shows the food support 6 in the same position as in Fig. 6 , but in the maximum allowed tilting position. This tilting position is created either by the user who presses on the front edge 22 of the food support 6, for example, to let the food to flow to the front edge or the focus of the food is located near the front edge 22 of the food support 6. The tilting forward food support 6 in this case prevented by the holding member 15 from exceeding the maximum predetermined tilt angle.

Fig. 8 shows an alternative extension device, in which the function of the locking element 14 is included in the guide member 13. As a result, the position of the retaining element in the Y direction shifts toward the front end 12.

The width of the attached to the running rail 9 elements, in particular guide element 13, locking element 14 and retaining element 15 is kept small to facilitate lateral gripping and to prevent fouling of the extension device.

A self-contained object of the invention is also a Einhängegitter, which has the features holding element 15, locking element 14 and guide member 13 and their features.
