Description

Technical Field

[0001] The present invention relates to a cooking appliance having a door for enclosing a cooking space and having a housing in which a storage space is constructed, the door being able to sink into the storage space, wherein a guide member is arranged in the storage space, and a guide rail for a guide slider of the cooking appliance is constructed at the guide member to guide the sinking movement of the door into the storage space. Background Technology

[0002] Cooking appliances with a sinkable door are known from DE 10 2018 201 950 A1 and DE 10 2020 208 891 A1, wherein the door is coupled to a guide slider, which is guided in a guide groove by means of rollers.

[0003] Furthermore, a cooking appliance with a retractable door is known from DE 10 2015 226 009 A1. There, the storage space for the door is also defined by lateral, vertical, and particularly plate-like sidewalls. Guide rails for sliding sliders or guide sliders are also constructed in these sidewalls, which function as technical components. In this design, the guide rails are constructed very low within the technical component when viewed along the height of the cooking appliance and therefore also along the height of the technical component. This allows for a specific sequence of door movement. Specifically, in this design, the front and rear ends of the guide rails are constructed almost immediately adjacent to the lower edge of the technical component. Therefore, the door is positioned very low both at the start and end of movement.

[0004] The sinkability of relatively wide doors is limited by this type of design because the structural space is restricted not only in width but also in height. Summary of the Invention

[0005] The object of this invention is to provide a cooking appliance with a retractable door, wherein the guidance of the guide slider is improved. Therefore, it should also be possible to provide a solution that improves flexibility in using different doors.

[0006] This objective is achieved by a cooking appliance having the features of claim 1.

[0007] This invention relates to a cooking appliance having a door for enclosing a cooking space. The cooking appliance further has a housing in which a storage space is constructed. The door is capable of sinking into this storage space. The storage space is a space separate from the cooking space of the cooking appliance. Food for cooking can be introduced into the cooking space. A guide member is arranged in the storage space, at which a guide rail for a guide slider of the cooking appliance is constructed to guide the sinking movement of the door into the storage space.

[0008] The guide component has a first upper guide rail when viewed along the height direction of the cooking appliance. The guide component also has a second lower guide rail, separate from the first upper guide rail and viewed along the height direction. The guide slider has multiple separate guide elements that simultaneously abut against both guide rails during movement of the guide slider to guide it.

[0009] At least one guide element is arranged to rest on the lower guide rail from above. At least one additional guide element is arranged to abut against the upper guide rail from below.

[0010] Therefore, this scheme enables the guide slider to move in a particularly advantageous and tolerancing manner.

[0011] In one embodiment, the guide slider has at least one lateral guide element separate from the guide element, which, when viewed along the width direction of the cooking appliance, can abut against, at least temporarily, the lateral guide rail of the cooking appliance for lateral guidance of the guide slider.

[0012] Therefore, as an additional solution to the very specific scheme having guiding elements and guide rails (which are specifically arranged relative to each other in the height direction and interact with each other, thus enabling movement of the slider relative to the guiding member with particularly minimized tolerances in the height direction), it is also possible to achieve guidance with similarly minimized tolerances in the direction perpendicular to the height direction, i.e., in the width direction. This achieves a scheme in which undesirable offset movement of the guide slider relative to the guiding member and / or lateral guide rails is avoided by a clearly defined guiding element that mechanically interacts with specific guide rails in both spatial directions of the guide slider, i.e., in the height and width directions. This scheme allows for particularly precise adherence to movements that should be performed, especially in the depth direction. This also has significant advantages for movements of the door into or out of the storage space. Thus, it is now possible to satisfy the relatively complex movement processes of the door with particularly precise and minimized tolerances. Another advantage is that clamping, opening, or tilting of the door, especially the door panel, can be reduced during sinking movements into the storage space or removal movements out of the storage space. This can significantly reduce or avoid undesirable force effects on the components mentioned, thereby also significantly reducing wear on these components during their lifespan.

[0013] The guide element abutting against the upper and lower guide rails can also be called a height guide element. This height guide element is specifically configured to pre-determine the position of the guide slider relative to the guide component along the height direction. The upper and lower guide rails can also be called height guide rails.

[0014] In one embodiment, viewed along the depth direction of the cooking appliance, at least one lateral guide element is arranged between two front guide elements and two rear guide elements. Therefore, the lateral guide element is positioned particularly relative to height guide elements arranged in pairs at different depth positions. This further improves the stability of guidance along these two mentioned spatial directions. It also improves the accuracy and tolerance-minimized coupling between the guide elements and their corresponding guide rails.

[0015] In one embodiment, viewed along the height direction, at least one lateral guide element is arranged between two guide elements, particularly height guide elements, arranged at different height positions. It is feasible that the guide elements abutting against the upper and lower guide rails have a first pair of such guide elements, which are arranged offset from each other along the height direction, particularly at different height positions, wherein for this purpose at least one lateral guide element is arranged between them when viewed along the height direction. However, in one embodiment, the lateral guide element can be arranged offset relative to this pair of guide elements along the depth direction.

[0016] The pair of guide elements, which rest against the upper and lower guide rails, can be positioned at the same depth along the depth direction.

[0017] As described above, a corresponding configuration can also be provided for another pair of guide elements abutting against the upper and lower guide rails. In one embodiment, the lateral guide elements can also be positioned relative to these two additional guide elements in a manner that is offset forward along the height direction, and particularly additionally along the depth direction.

[0018] Preferably, two guide elements abut against the lower guide rail from above, and at least two additional guide elements abut against the upper guide rail from below. This provides four guide elements, specifically exactly four height guide elements, which are mechanically coupled in pairs to the upper and lower guide rails for sliding or rolling along them. In particular, this allows for a very symmetrical arrangement of the guide elements, especially the height guide elements. This further improves the accuracy of guiding the movement of the guide slider.

[0019] In one embodiment, at least one guide element can be a roller. It is feasible that all guide elements are formed of rollers. This enables particularly uniform and smooth movement of the guide slider along the guide rail.

[0020] In other embodiments, at least one guide element can be a sliding bearing. It is feasible for all guide elements to be constructed as sliding bearings. In such embodiments, the guide elements can be designed very space-efficiently and compactly. Thus, the structure of the guide slider is minimized, particularly along the height direction. The sliding bearing is arranged at the guide slider especially where there is no possibility of its own relative movement.

[0021] In one embodiment, the lower guide rail is constructed in a straight line. This lower guide rail extends horizontally along the depth direction of the cooking appliance. Such a straight guide rail requires almost no space along the height direction because it has no curved or bent sections. Therefore, the space-saving design can be further improved when viewed along the height direction.

[0022] In one embodiment, the upper guide rail is constructed in a straight line. This upper guide rail extends particularly horizontally along the depth direction of the cooking appliance. This also allows for an advantage in terms of a compact structure along the height direction. This also advantageously contributes to reducing storage space in terms of height and thus increasing cooking space.

[0023] However, it is also feasible to construct the guide components in two pieces. In this regard, the first guide element can have an upper guide rail, and the second guide element can have a lower guide rail. In such an embodiment, the guide elements can also be arranged spaced apart from each other when viewed in the height direction.

[0024] In one embodiment, the guide slider is coupled to the door using a hinge device of the cooking appliance. This hinge device supports the pivoting movement of the door when it is moved into and out of the storage space, so that the pivoting movement can be performed independently of the sliding movement of the guide slider. Specifically, the hinge device, viewed as a whole, can be positioned fixedly within the housing of the cooking appliance. In particular, it can be arranged at the bottom structural component of the housing. Preferably, the hinge device has its own guide component, such as a roller. In one embodiment, this guide component can be embedded in a guide groove, such as a guide channel, laterally constructed at the door. Thus, the door, especially the door panel, can move relative to the hinge device and is guided in movement by this embedded guide element of the hinge device. Alternatively, the door, especially the door panel, may have a coupling device in a lower portion. This coupling device is configured for coupling with the guide slider. In particular, this hinged coupling is permanently constructed so that the door panel can move relative to the guide slider, and also pivot. Specifically, this coupling hinge grounding structure between the coupling device and the guide slider is specified.

[0025] In one embodiment, at least one guide element, viewed as a whole, is variably supported in position at a bracket of the guide slider. This allows the guide element to be in particularly advantageous continuous contact with the guide rail. Tolerances can then be compensated for by changes in the position of the guide element at the bracket. In another embodiment, at least one guide element can be arranged at the bracket in a spring-supported manner. This allows for automatic position changes through loading caused by the spring force of the guide element. This results in a particularly advantageous, robust system that is very rapid in terms of position changes.

[0026] Preferably, guide sliders and guide components are constructed at opposite ends when viewed along the width direction of the cooking appliance. The two guide sliders and / or two guide components can be constructed identically. In particular, the explanations and embodiments mentioned above apply to these two guide sliders. The coupling device mentioned above can also be coupled to the two guide sliders, especially to the connecting rod that connects the two guide sliders.

[0027] The guide sliders, constructed on opposite sides, are preferably connected to the connecting rod, thereby maintaining their position relative to each other and preventing tilting or twisting relative to each other in terms of movement. This positional coupling between the guide sliders enables shock-free and uniform movement along the guide rail. The door is advantageously connected to the guide slider at its lower end, particularly rotatably. The guide slider is a separate component from the hinge device. The guide slider is preferably connected to the door in a motion-coupled manner, wherein a rotation axis is constructed at the connection point, about which the door can then twist relative to the guide slider. In contrast, the hinge device, having the rollers described above, enables not only relative movement about rotation relative to each other, but also relative sliding movement between the door and the hinge arm through the guide grooves or guide rails, also constructed on the side edges and already mentioned, located in the door.

[0028] In one embodiment, at least one guide rail is constructed in a groove-like manner. This allows the guide rail boundary to be constructed perpendicular to its longitudinal axis. This limits and, in particular, prevents undesirable movement of the guide element perpendicular to the longitudinal axis of the guide rail. This achieves particularly straight guidance of the guide element within the guide rail, especially along the depth direction.

[0029] In one embodiment, at least one guide rail is constructed in a raised shape when viewed in cross-section and therefore perpendicular to its longitudinal axis. Specifically, the guide rail can be convexly curved or trapezoidally constructed. This shape of the guide rail also prevents undesirable slippage of the guiding element relative to the guide rail when viewed in the width direction. This shape of the guide rail also achieves particularly straight guidance of the guiding element at the guide rail.

[0030] In one embodiment, the working surface of the guide element has a groove shape, and the raised area of ​​the guide rail is embedded in the groove shape. This complementary design of the working surface of the guide element on one hand and the working surface of the guide rail on the other hand supports the advantages mentioned above to a particular extent.

[0031] In an advantageous embodiment, the storage space is specified to have a net width of less than or equal to 45 mm, particularly between 40 mm and 44 mm, at least at the entrance along the height direction. Preferably, the net width is constructed within at least 50%, preferably at least 80%, and particularly at least 90% of the depth of the storage space as measured along the depth direction, when viewed along the height direction.

[0032] This type of design allows for a particularly compact storage space, thus providing maximum cooking space. If the cooking appliance's casing has a common standard size, this compact storage space maximizes cooking space. Nevertheless, it still allows for easy access into and out of the storage space through a wide doorway.

[0033] In an advantageous embodiment, the door is specified to have a thickness between 35 mm and 45 mm, particularly between 38 mm and 42 mm, and preferably 40 mm. It is also feasible in this type of design for the door to have a multi-panel assembly with at least three panels, wherein a front panel, an inner panel, and at least one intermediate panel can be provided. The panels are oriented parallel to each other and are plate-like elements, particularly made of true glass. With multiple door panels, particularly at least four such separate panels, the cooking appliance can also be constructed to have a pyrolysis function.

[0034] In this type of design (where the door has the advantageous thickness mentioned above, and the storage space has the advantageous height dimension mentioned above, where the thickness is always less than the height dimension of the storage space), it is possible to move the relatively thick door into the storage space, which is only slightly higher. Through the aforementioned mechanical structure, it is possible to achieve the corresponding door movement, either in or out, even though the storage space is only slightly higher than the door's thickness. Specifically, this is achieved by the following: during the pivoting motion, especially from the closed position to the horizontally open position, the door does not move into the storage space or only slightly, and the main inward movement occurs from the horizontally open position, thus the linear movement of the door into the storage space occurs essentially after the pivoting motion.

[0035] In an advantageous embodiment, it can be additionally or alternatively specified that the door, viewed from its outer side in the width direction, has a width between 530 mm and 545 mm, particularly between 535 mm and 540 mm. Such a wide door allows for improved clearance design. Specifically, this improves clearance relative to adjacent components, such as, for example, the front slats, which are constructed as visible members or external parts of the cooking appliance on the front side. In particular, this clearance can be set relatively small. In this respect, the aforementioned design of the door with its specific width allows for a unified front appearance between cooking appliance variants (one having only a flip-up door, the other having a recessable door as explained above). In the closed state of the door, a unified appearance can then be provided in both cooking appliance variants.

[0036] The advantageous implementations of the cooking appliances mentioned above can be regarded as advantageous implementations of other independent aspects of the cooking appliances.

[0037] The terms "above", "below", "in front", "behind", "horizontally", "vertically", "depth", "width", and "height" are used to describe the position and orientation given to an observer who is using and arranging the appliance in accordance with regulations and who is then standing in front of the appliance and looking in the direction of the appliance.

[0038] Further features of the invention are derived from the claims, drawings, and description of the drawings. The features and combinations of features mentioned above in the specification, as well as those mentioned below in the description of the drawings and / or shown separately in the drawings, can be used not only in the separately described combinations but also in other combinations without departing from the framework of the invention. Therefore, the following embodiments can also be considered as included and disclosed as embodiments of the invention, which are not explicitly shown and illustrated in the drawings but can be derived and produced by separate combinations of features from the illustrated embodiments. Therefore, embodiments and combinations of features that do not possess all the features of the initially stated independent claims can also be considered as disclosed. Furthermore, embodiments and combinations of features that go beyond or deviate from the combinations of features set forth in the reference relationships of the claims can be considered as disclosed, particularly through the embodiments described above.

[0039] Embodiments of the present invention will now be explained in more detail with reference to the schematic accompanying drawings. Wherein: Figure 1 A perspective view of an embodiment of a cooking appliance according to the present invention is shown. Figure 2 It shows according to Figure 1 A schematic vertical cross-sectional view of a cooking appliance. Figure 3 It shows according to Figure 1 A side view of an embodiment of a cooking appliance, showing a guide slider and guide components.

Detailed Implementation

[0040] In the accompanying drawings, elements that are identical or have the same function are given the same reference numerals.

[0041] exist Figure 1The diagram illustrates a household appliance 1, configured as an oven, in a schematic perspective view. Appliance 1 has a housing 2 within which a cooking space defined by a muffle oven (not shown) is constructed. Food for cooking can be introduced into the cooking space. The cooking space can be closed off at the front by a door 3. Figure 1 The door is shown in its closed end position. A handle 4 is constructed on the front side of the door 3.

[0042] In addition, the oven has an operating device 5, which, by way of example, has a display unit 6 and operating elements 7 and 8 in terms of position and display.

[0043] The housing 2 can have walls 9, 10, 11 and 12.

[0044] Door 3 can be pushed into or sunk into housing 2 in its lower region 13, and door 3 can be pushed into or sunk into housing 2 from Figure 1 This is the case when the closed end position shown is transferred to the fully open and sunken end position. The door 3 is then arranged in the free space of the housing 2 in a sunken manner, wherein a storage space 14 is constructed through the free space and is arranged below the cooking space and separated from the cooking space by a corresponding separating wall.

[0045] Door 3 is connected to a door hinge, which is exemplarily shown and labeled as an example of hinge devices 15 and 16, and is pivotable by the door hinge and can be moved into and out of the aforementioned storage space 14.

[0046] exist Figure 2 The diagram shows a vertical cross-sectional view (section plane yz plane) of cooking appliance 1. The cooking space 17 defined by the mentioned muffle oven can be identified here.

[0047] It can be identified here that the storage space 14 has a net width w, which is measured along the height direction (y direction) and is particularly between 40 mm and 44 mm, preferably between 42 mm and 43 mm.

[0048] The thickness d of door 3 ( Figure 2 The preferred size is between 38 mm and 42 mm, especially 40 mm.

[0049] The measurement along the width direction (x direction) of door 3, such as Figure 1 The width b indicated therein is preferably between 530 mm and 545 mm, and more particularly between 535 mm and 540 mm.

[0050] The front panel 3a, inner panel 3b, and middle panel 3c of door 3 are also shown.

[0051] For example, a view shown along the negative x-direction. Figure 3 As shown, the hinge device 15 can have a hinge housing 18. This hinge housing can be fixedly arranged within the housing 2. The hinge device 15 further has a bearing unit 19 with a bearing bracket 20. At least one guide element 21, here a roller, is rotatably supported at the bearing bracket 20. This guide element 21 is embedded in a groove-shaped guide channel 22, which is constructed at the side edge 23 of the door 3 and extends in the height direction when the door 3 is closed. Therefore, the guide element 21 is guided in the guide channel 22, which is laterally open outwards when viewed in the width direction.

[0052] The guide groove 22 is specifically constructed at the door panel 24 of the door 3. The door panel 24 is a plate-shaped front element of the door 3.

[0053] The door 3 also has a coupling device 25. Using this coupling device 25, the door panel 24 is coupled to at least one guide slider 26 of the door 3. Specifically, guide sliders 26 are arranged on opposite sides along the width direction. In particular, a hinged connection is constructed here, so that the door panel 3 can pivot hingedly relative to, and especially about, an axis oriented along the width direction (x-direction) while coupled to the guide sliders 26.

[0054] The cooking utensil 1 also has guide members 27. The guide members 27 are arranged in the storage space 14. In particular, guide members 27 are arranged on opposite sides along the width direction.

[0055] The guide slider 26 is guided at the guide member 27. The guide member 27 can be constructed in a rod-like or beam-like manner. The guide member extends along its longitudinal axis in the depth direction (z-direction) of the cooking appliance 1. The guide member is particularly disposed at the side wall, which laterally defines the storage space 14. In the illustrated embodiment, the guide member 27 has an upper guide rail 28 viewed in the height direction (y-direction) of the cooking appliance 1. In one embodiment, the upper guide rail 28 is straight, particularly within at least the following sections, along which the guide slider 26 can move, particularly using a guide element. Furthermore, the guide member 27 has a lower guide rail 29 viewed in the height direction. The lower guide rail is disposed below the upper guide rail 28. In one embodiment, the lower guide rail 29 is straight, particularly within at least the following sections, along which the guide slider 26 can move, using a guide element.

[0056] The two guide rails 28 and 29 are oriented in particular to be parallel to each other.

[0057] The guide slider 26 shown here is the guide slider on the right side when viewing the cooking appliance 1 from the front. In one embodiment, the cooking appliance 1 has a second guide slider 26. This second guide slider can preferably be constructed based on the guide slider 26. This second guide slider is then the guide slider on the left side when viewing the cooking appliance 1 from the front. If two such guide sliders 26 are present, they can be connected using a connecting rod (not shown) extending in the width direction.

[0058] In one embodiment, the guide slider 26 has a plurality of, in particular exactly four, separate guide elements 30, 31, 32, and 33. Figure 3 In this embodiment, only four guide elements 30 to 33 are present, arranged at the illustrated guide slider 26 and rolling on guide rails 28 and 29. In this embodiment, all four guide elements 30 to 33 are configured as rollers. The guide elements 30 to 33 have working surfaces 30a, 31a, 32a, and 33a.

[0059] In addition, as in Figure 3 As can be identified, the four guide elements 30, 31, 32, and 33 are preferably arranged in pairs relative to each other not only along the height direction but also along the depth direction. Thus, guide elements 30 and 31 are staggered relative to each other along the height direction, but at the same depth along the depth direction. Therefore, these guide elements form a pair of front guide elements 30 and 31. These guide elements 30 and 31 can also be referred to as height guide elements. This is because these guide elements are in mechanical contact with guide rails, namely the upper guide rail 28 and the lower guide rail 29, which are respectively staggered relative to them along the height direction, using their working surfaces 30a and 31a.

[0060] In the embodiment, an additional pair of guide elements 32 and 33 are specified. These guide elements are also height guide elements. These guide elements are arranged offset from each other in the height direction, but are arranged at the same depth relative to each other in the depth direction. These guide elements 32 and 33 are also in direct contact with guide rails 28 and 29 that are offset from them in the height direction, using their working surfaces 32a and 33a.

[0061] As can also be identified, the upper front guide element 30 is positioned at the same height as the upper rear guide element 33. Furthermore, the lower front guide element 31 is positioned at the same height as the lower rear guide element 32. It can be seen that the upper guide elements 30 and 33 abut against the upper guide rail 28 from below. Furthermore, the lower guide elements 31 and 32 abut against the lower guide rail 29 from above.

[0062] Guide elements 30 to 33 are arranged at the bracket 34 of the guide slider 26.

[0063] Such external reasons Figure 3 As can be identified from the diagram, the guide slider 26 has at least one additional guide element, which is here a lateral guide element 35. This means that, unlike the other guide elements 30 to 33, this lateral guide element is not positioned for direct contact with the guide rails 28 and 29 that are misaligned relative to it in the height direction, but rather is positioned to conformally abut against the guide rail that is misaligned relative to it in the width direction and thus against the lateral guide rail 36. Figure 4 At this location, only one such lateral guide element 35 is provided. This lateral guide element has an action surface 35a, which is configured to directly abut against the lateral guide rail 36. The lateral guide element 35 can be configured as a roller. The lateral guide element preferably has a rotation axis 35b. This rotation axis is here exemplarily oriented vertically and therefore along the height direction. However, it is also possible for the rotation axis 35b to be angled relative to the vertical line. The lateral guide element can then also be arranged to be tilted upwards or downwards. In particular, the side of the lateral guide rail 36 is configured for contact and can then be correspondingly tilted, so that the action surface 35a also abuts against the lateral guide rail 36 over a large area and can roll.

[0064] like Figure 3 As shown, a lateral guide element 35 is also arranged at the bracket 34, and preferably other guide elements 30 to 33 can also be rotatably supported at the bracket.

[0065] Lateral guide element 35 is arranged between guide elements 30 and 31 and / or between guide elements 32 and 33 when viewed in the height direction. When viewed in the depth direction, lateral guide element 35 is arranged rearwardly offset relative to guide elements 30 and 31. This lateral guide element is arranged forwardly offset relative to guide elements 32 and 33, especially when viewed in the depth direction.

[0066] At least one guide element 30, 31, 32, 33 and / or at least one lateral guide element 35 can be arranged in a spring-supported manner at the bracket 34. This specifically means that the guide elements 30, 31, 32 and 33 can be arranged in a spring-supported manner along the height direction, and the lateral guide element 35 can be arranged in a spring-supported manner along the width direction.

[0067] exist Figure 4 It shows Figure 3 The components in the diagram are shown in the front view and thus illustrated in accordance with Figure 1 The design scheme on the right side of the cooking utensils. Particularly feasible is... Figure 3The corresponding additional guide sliders 26 shown are also arranged on the left side in the storage space 14 of the cooking appliance 1, thus presenting such guide sliders opposite each other along the width direction. A corresponding guide member 27 can also be provided at this left position of the storage space 4, and the additional guide slider 26 can be movably arranged relative to this guide member. In such an embodiment, the two guide sliders 26 can be connected to each other by a connecting rod, so that they are rigidly coupled to each other and guided synchronously along the depth direction. In one embodiment, the connecting rod can also be a component of the coupling device 25.

[0068] exist Figures 5a to 5d The diagram illustrates embodiments of the shapes of the functional surfaces of the guiding element and the guide rails. The cross-sectional views shown here should not be taken as definitive interpretations, but rather represent some feasible examples. Therefore, in Figure 5a The guide element 30, having its working surface 30a, is illustrated exemplarily here. The guide rail 28, exemplarily shown here, is preferably defined laterally by boundary walls 37 and 38 when viewed along its width. Thus, a groove-like shape is formed in the cross-sectional view perpendicular to the longitudinal axis of the guide rail 28. A rotation axis 30b is also drawn, about which the guide element 30, configured as a roller, can rotate. In this embodiment, the working surface 30 is constructed linearly in this cross-sectional view.

[0069] exist Figure 5b The text shows the data based on... Figure 5a The diagram shows that the working surface 30a is grooved. This working surface is particularly concave and curved. In the embodiment shown here, the guide rail 28 is convexly shaped. This guide rail particularly has a convexly curved arched structure. Thus, the working surface 30a, with its concave shape, rests on the convexly curved guide rail 28. Therefore, slippage or offset of the guide element 30 relative to the guide rail 28 in the width direction is particularly avoided or significantly limited. Figure 5c The image shows something similar to Figure 5b The embodiment. The groove shape of the working surface 30a is here similar to... Figure 5b The embodiments described in this paper differ from those in the present invention. The groove shape here is notched in cross-section, particularly V-shaped, thus not forming a continuous concave curved region. Figure 5d Another embodiment is shown. In this embodiment, the working surface 30a is also constructed in a groove shape. However, here the profile is angular. Preferably, the trapezoidal cross-sectional shape of the guide rail 28 is adapted to this profile. Here, corresponding interlocking is thus achieved, as in Figure 5d As shown.
