Description

[0001] The invention relates to a dishwashing tray, in particular a cup tray, for arrangement on a dishwashing basket of a dishwasher.

[0002] Dishwasher baskets, when used as intended, serve to hold items to be cleaned and are well known from the prior art, which is why a separate printed proof is not required here.

[0003] A dishwashing basket known from the prior art is typically formed from a wire mesh made of plastic-coated wire and provides surfaces for holding items to be cleaned. It may also include items to be held in place by spikes, loops, and / or the like.

[0004] It is also known from the prior art to equip dishwashing baskets with dishwashing trays, in particular those attached to them. These trays can be pivoted from a working position to a non-working position and vice versa.

[0005] In their operating position, familiar dishwashing trays are designed to hold relatively small items, such as cups, which is why they are also called cup trays. Similarly small items can be positioned below the dishwashing tray in its operating position, thus providing a total of two levels for holding small items.

[0006] In its non-use position, the dish support is pivoted so that it extends essentially in the vertical direction of the dish basket. This allows the dish basket to accommodate larger items on two levels instead of smaller items. In dish baskets known in the prior art, such larger items are typically supported laterally by the dish support when not in use, thus reducing the available width for the items.

[0007] Although dishwashing baskets of the type described above have proven their worth in everyday practical use, there is room for improvement. The aim is, in particular, to utilize the space provided by a dishwashing basket for dishes even more efficiently and to simplify its use for the consumer.

[0008] Therefore, based on the above, the Task The invention aims to provide a dishwashing tray of the type mentioned above, which is designed to simplify handling by the user and also allows for more effective use of a dishwashing basket that provides the tray. Furthermore, the tray is intended to ensure the secure storage and support of the items being washed.

[0009] To SolutionThe invention proposes a dishwashing tray, in particular a cup tray, with a base body providing a support surface for arrangement on a dishwashing basket of a dishwasher, which has a positioning device cooperating with a counter contour on the dishwashing basket side, which is designed for a rotatable and movable arrangement of the base body on the dishwashing basket and is configured to move the base body relative to the dishwashing basket from a working position to a non-working position and vice versa, wherein the positioning device has bearing cams cooperating with the counter contour of the dishwashing basket which provide bearing recesses aligned along an axis of rotation.which, in the operating position of the base body, block a movement of the base body in the vertical direction of the dish basket, and wherein the positioning device for securing the position of the base body in the depth direction of the dish basket has first and second guide tabs, wherein the first guide tabs in the operating position of the base body and the second guide tabs in the non-operating position of the base body are in contact with the counter culture of the dish basket.

[0010] The dishwashing tray according to the invention has a base body. This can optionally be equipped with a hinged strip that can pivot on it.

[0011] In its fully assembled state, the base unit is attached to the dishwasher basket. The base unit is designed to be rotatable and movable relative to the dishwasher basket. This allows the user to move the base unit from an operating position to a non-operating position and vice versa.

[0012] According to the invention, the base body has a positioning device that interacts with a counter contour provided by the dishwashing basket. This positioning device is designed to allow the base body to be rotatably and movably arranged on the dishwashing basket and to enable it to be moved from a working position to a non-working position and vice versa.

[0013] The positioning device has bearing cams that interact with the counter contour of the dishwashing basket. These bearing cams provide aligned bearing recesses along a rotational axis. This allows the base body to be rotatably arranged on the dishwashing basket. The bearing recesses are designed such that, in the base body's operating position, they prevent any vertical movement of the base body along the dishwashing basket. Therefore, when the base body is in its operating position, only rotation of the base body is possible, not vertical movement. Thus, the base body is secured against movement in its operating position according to the invention.

[0014] The positioning device further features first and second guide tabs to secure the position of the base body in the depth direction of the dishwashing basket. Under normal operating conditions, these guide tabs are in contact with the opposite contour of the dishwashing basket, thus securing the dishware support in the depth direction as well. According to the invention, the first guide tabs are in contact with the opposite contour of the dishwashing basket when the base body is in use, and the second guide tabs are in contact with it when the base body is out of use. This ensures that the dishware support is secured in the depth direction of the dishwashing basket, regardless of its position – that is, whether it is in use or out of use.

[0015] The dishwashing tray according to the invention is advantageously simple in design, which enables simple and cost-effective manufacturing and assembly. At the same time, functional reliability is ensured, since the position locking mechanism designed according to the invention guarantees that the dishwashing tray remains in place both in use and in non-use positions. This allows for the safe storage and placement of dishes without the risk of unintentional pivoting or movement of the dishwashing tray, which could result in damage to the dishes.

[0016] The bearing cams provided according to the invention have bearing recesses that serve two structural purposes. Firstly, the bearing recesses, in combination with the counter contour of the dishwashing basket, enable a rotatable arrangement of the base body of the dishwashing support. Secondly, the bearing recesses prevent any movement of the base body while it is in its operating position. Therefore, to move the base body from its operating position to its non-operating position, it must first pivot, thus releasing the movement restriction imposed by the bearing recesses. Movement of the base body is therefore only possible after it has been rotated. The bearing recesses thus create an effective movement lock for the base body in its operating position.

[0017] To reliably prevent unintentional displacement of the base body in the downward direction of the dishwashing basket, guide tabs are provided according to the invention. In normal use, these tabs bear against the opposite contour of the dishwashing basket, thus being in contact with it, which prevents the base body from moving downwards. In combination with the bearing recesses described above, this results in a movement lock in the operating position of the base body in both the vertical and vertical directions.

[0018] Once the base is rotated from its operating position, the dishwashing basket can be moved vertically, allowing it to be switched from its operating position to its non-operating position and vice versa. However, downward movement of the dishwashing basket remains prevented by guide tabs that are in contact with the opposite contour of the dishwashing basket. First and second guide tabs are provided: the first tabs prevent downward movement of the dishwashing basket when the base is in its operating position, and the second tabs prevent such movement when the base is in its non-operating position.

[0019] Depending on the position of the base, the first guide tabs and / or the second guide tabs come into contact with the counter contour of the dishwashing basket. Due to the design, some guide tabs will disengage from the counter contour when the other guide tabs are already in contact with it. This allows for very simple handling for the user, as no further measures are required to secure the position in the depth direction.

[0020] In the operating position of the base unit, the first guide tabs are in contact with the opposite contour of the dishwashing basket. As soon as the base unit is rotated to its non-operating position, both the first and second guide tabs are in contact with the opposite contour of the dishwashing basket. If, starting from this rotated position, the base unit is then lowered by moving it, the first guide tabs disengage, while the second guide tabs remain engaged with the opposite contour. Thus, a transfer of contact occurs from the first to the second guide tabs. In the reverse movement, that is, when moving the base unit from the non-operating position to the operating position, this transfer between the guide tabs occurs in reverse order.In any case, it is therefore ensured that a movement of the base body in the depth direction of the dish basket is blocked, so that positional locking is advantageously guaranteed.

[0021] The invention proposes a simple design overall, enabling easy operation by the user and thus allowing for effective use of the dishwashing support. The dishwashing support is held securely and precisely in any position, preventing unwanted movement or rotation, which also protects the items being cleaned.

[0022] In this design, the base body of the dishwashing support according to the invention, when not in use, is positioned so far downwards in the vertical direction of the dishwashing basket that items typically placed at an angle in the basket can rest directly against the corresponding side wall of the basket, and not—as in the prior art—with the raised dishwashing support interposed. The base body of the dishwashing support, when not in use, is thus located in the storage space of the dishwashing basket that is unused in the prior art. The dishwashing support therefore enables more efficient use of the dishwashing basket.

[0023] According to a further feature of the invention, the positioning device has support ribs which, in combination with the bearing cams, block a movement of the base body in the width direction of the dishwashing basket when the base body is in use position.

[0024] According to this embodiment, in the operating position of the base body, movement of the dishwashing basket is blocked not only in the vertical and horizontal directions, but also in the horizontal direction. This horizontal positioning of the dishwashing basket is achieved by support ribs that are formed on the base body opposite the bearing cams. InIn the operating position, both the bearing cams and the support ribs are in contact with the corresponding contour of the dishwashing basket, thus "trapping" the positioning device in the width direction of the basket and preventing movement of the base body in this direction. This restriction can be released by first rotating the base body, as previously described, instead of moving it. This rotation causes the support ribs to lose contact with the contour of the dishwashing basket, allowing the base body to then be moved downwards in the height direction of the basket.

[0025] According to a further feature of the invention, a support rib has a centering recess on its opposite contour that interacts with the opposite contour of the dishwashing basket. This centering recess on the support rib ensures that the base body is correctly aligned with the opposite contour of the dishwashing basket in its intended position. The base body is thus centered, so that it is not only secured in its position but also correctly aligned in its position. This ensures that when the user moves the base body from its position to its non-positioning position, the positioning aid does not become unintentionally tilted or jammed against the opposite contour of the dishwashing basket. This further increases operational reliability.

[0026] According to a further feature of the invention, the positioning device has a rotation stop which, in the non-use position of the base body, is in contact with the opposite contour of the dishwashing basket.

[0027] This anti-rotation stop also serves to ensure proper function. It guarantees that the base is rotated sufficiently during a twisting motion so that, after the completion of the intended rotation, the base can be lowered, i.e., moved downwards in the vertical direction of the dish rack. A user-initiated twisting motion of the base continues until the anti-rotation stop comes into contact with the opposite contour of the dish rack. Once this is achieved, the base is precisely aligned, extending essentially perpendicular to the dish rack in its longitudinal direction. In this position, the base can be moved downwards in the vertical direction of the dish rack without collision. A distinction can therefore be made between a working position and a non-working position of the base.The dishwashing tray rests on a defined intermediate position in which the base body is already rotated relative to the dish basket as intended for transfer to the non-use position, but has not yet moved. In this intermediate position, the previously described guide tabs, i.e., both the first and second guide tabs, are all in contact with the opposite contour of the dish basket, so that a tilt-free movement of the base body in the vertical direction is guaranteed in every case.

[0028] According to a further feature of the invention, it is provided that a storage recess is equipped with an undercut effective in the vertical direction of the dishwashing basket when the base body is in the operating position.

[0029] The bearing recess, as previously described, ensures that the base body can be rotated around an axis of rotation provided by the counter contour of the dishwashing basket. The bearing recess provides an undercut, specifically an undercut effective in the vertical direction of the dishwashing basket, thus preventing vertical movement of the base body when it is in its operating position. Only when the base body is rotated from its operating position into the previously described intermediate position does the bearing recess, or rather the undercut it provides, release the counter contour provided by the dishwashing basket to such an extent that vertical movement of the base body is now possible.As long as the base body is not in this intermediate position, the counter contour provided by the dish basket is encompassed by the bearing recess of the bearing cam to such an extent that it collides with it in the vertical direction of the dish basket, which blocks a movement in the vertical direction.

[0030] According to a further feature of the invention, the undercut is provided by an elastically pivotable lever of the bearing cam. This design is particularly preferred for reasons of simplified assembly and disassembly. The lever providing the undercut can be elastically pivoted to the side, allowing assembly by simply snapping the mating contour into the corresponding bearing recess through elastic movement of the lever. Disassembly is equally simple, as the user elastically deforms the lever, which then allows the mating contour of the dishwashing basket to be unthreaded from the bearing recess of the corresponding bearing cam.

[0031] According to a further feature of the invention, the base body and the positioning device are formed in one piece from plastic. This results in a single-piece component that can be easily produced and assembled. The dishwashing tray has a base body which preferably has two positioning devices: a left positioning device and a right positioning device, depending on the width of the base body.

[0032] The invention further proposes a dishwashing basket for rotatably and movablely receiving a dishwashing tray of the type according to the invention. Such a dishwashing basket is characterized by a counter contour that interacts with the positioning device of the dishwashing tray, and which has a corresponding wire bracket for each bearing cam of the positioning device. Therefore, to arrange a dishwashing tray according to the invention on a dishwashing basket, only one additional wire bracket is required beyond the basket's mesh. The existing wire mesh of the dishwashing basket can otherwise serve as the counter contour.

[0033] According to a further feature of the invention, the wire bracket is U-shaped and comprises a base wire and two wire extensions arranged at each end. These wire extensions serve, on the one hand, to support the dishwashing tray, particularly in its operating position, in the vertical direction, and on the other hand, to define the axis of rotation around which the dishwashing tray or its base body is to be rotated to move it from an operating position to a non-operating position. With just one component, the counter contour required for the positioning aids is created in a simple manner. This counter contour, as already described, allows both a traversing and rotating movement of the dishwashing tray and also provides a locking mechanism, whether in the operating or non-operating position of the dishwashing tray, as explained above.

[0034] According to a further feature of the invention, a first wire extension of a first wire bracket and a first wire extension of a second wire bracket are aligned and together define an axis of rotation for the positioning device. Each positioning device of the dishwashing tray is thus assigned a wire bracket. Both wire brackets each have a wire extension, specifically a first wire extension, with the two first wire extensions aligning with each other in the depth direction of the dishwashing basket. This defines the axis of rotation around which the dishwashing tray can rotate in the manner already described.

[0035] According to a further feature of the invention, the counter contour of the dishwashing basket also has guide wires which, in the non-use position of the dishwashing tray, interact with the associated second guide tab and the associated anti-rotation stop of the positioning device. It is preferred that such a guide wire is provided by the wire mesh of the dishwashing basket that is already present. In this respect, no additional components are required, which simplifies manufacturing and assembly.

[0036] The invention further proposes a dishwasher with a dishwashing basket of the type according to the invention and a dishwashing tray of the type according to the invention that is held therein. Such a dishwasher offers the advantages already explained above.

[0038] Fig. 1A purely schematic side view of a dishwasher 1 according to the invention is shown. The dishwasher 1 has a housing 2, which accommodates a wash container 3, in a manner known per se. The wash container 3, in turn, provides a wash chamber 4 for receiving items to be cleaned. For loading the wash chamber 4 with items to be cleaned, the wash container 3 has a loading opening 5. This loading opening 5 can be closed in a fluid-tight manner by means of a wash chamber door 6, the wash chamber door 6 being pivotably mounted about a horizontal pivot axis.

[0039] In normal use, the items to be cleaned are sprayed with dishwashing liquid, for which purpose the dishwasher 1 has a spray device 8. In the illustrated embodiment, the spray device 8 includes two spray arms 9. However, additional spray arms can also be provided.

[0040] Dishwashing baskets are used to hold items to be cleaned, the illustration being according to Fig. 1 Three dishwashing baskets, 10, 11, and 67, can be identified. These dishwashing baskets 10, 11, and 67 are arranged one above the other in the vertical direction 7, with dishwashing basket 10 serving as the lower basket, dishwashing basket 11 as the upper basket, and dishwashing basket 67 as the cutlery drawer.

[0041] The upper basket 11 is equipped with a dishwashing tray 12 according to the invention, as can be seen from the further figures.

[0042] Fig. 2 shows the dishwashing basket 11 with a dishwashing support 12 in its first operating position. Figures 3 and 4 reveal a second usage position of the dishwashing tray 12.

[0043] As can be seen in particular from a review of the Figures 8 and 9The dishwashing tray 12 has a base body 13 and a hinged strip 14 pivotally mounted on it. The hinged strip 14 can be moved from a first operating position, as described in Fig. 2 shown, in a second usage position, as shown in Fig. 3 or 4 is shown, and vice versa.

[0044] The folding rail 14 has a longitudinal edge 15 that serves as a support edge for items picked up from a dishwashing platform 19 of the dishwashing basket 11. This relationship is particularly evident from a comparison of the Figures 2 and 3In both cases, the dishwashing tray 12, thanks to its base 13, serves to hold a dishwashing item in the form of a cup 16. In the first position of use of the dishwashing tray 12, the folding bar 14 is folded upwards, so that the dishwashing tray 12 serves to support dishwashing items in the form of stemmed glasses 17. The stems of the stemmed glasses 17 rest against the longitudinal edge 15, which is wavy to separate the stemmed glasses 17.

[0045] To support a dishwashing item in the form of a cup 18, the folding strip 14 is to be rotated downwards, that is, with reference to the drawing plane, towards Fig. 3 clockwise, so that it assumes its second position of use. In In this second position of use, the longitudinal edge 15 of the folding strip 14 is moved downwards in the vertical direction 7 so far that even a dishwashing item in the form of a cup 18 can be supported, as can be seen from the illustration. Fig. 3 results.

[0046] Fig. 5 This second operating position of the dishwashing tray 12 is also partially shown in a cutaway view. As can be seen particularly from this illustration, in this second operating position the folding bar 14 is pivoted clockwise relative to the base body 13.

[0047] The Figures 2 and 3 Each shows a usage position of the dishwashing tray 12, namely a first usage position according to Fig. 2 and a second usage position according to Fig. 3 . Fig. 6 However, this reveals a non-use position of the dishwashing support 12, in which position the dishwashing support 12 has moved downwards in the vertical direction 7. In this position of the dishwashing support 12, the dishwashing surface 19 provided by the dishwashing basket 11 is fully accessible, which allows for the arrangement of a dishwashing item in the form of a cup 18 in the Fig. 7 The version shown is shown.

[0048] Fig. 8 The schematic exploded view shows that the dishwashing surface 12 is formed from a base body 13 and a hinged strip 14. The hinged strip 14 itself is divided into three parts: a first strip body 20 and a second strip body 21. An intermediate layer 22, preferably made of a soft, elastic plastic material, is arranged between these two strip bodies 20 and 22. This intermediate layer 22 projects beyond the two strip bodies 20 and 21 with respect to the longitudinal edge 15 provided by the hinged strip 14, so that, in the intended use, any dishwashing items are supported by the soft, elastic intermediate layer 22 of the hinged strip 14, as also shown in the illustration. Fig. 5 This can be seen.

[0049] Fig. 9 shows the assembled state of the dishwashing tray 12. The further Figures 10 to 17Figure 1 shows the articulated arrangement of the hinge strip 14 on the base body 13, as explained below.

[0050] As can be seen from a synthesis of the Figures 10 to 17 The base body 13 has a first hinge element 23, and the hinge strip 14 has a second hinge element 24 that interacts with it. Together, the hinge elements 23 and 24 form a hinge assembly 25. A plurality of such hinge assemblies 25 can be provided for the hinged arrangement of the hinge strip 14 on the base body 13, such as, for example... Fig. 8 shows.

[0051] As in particular a synthesis of Figure 12 and 13 As can be seen, the first joint element 23 has a projection 26 that provides a bearing eye 27. The second joint element 24, meanwhile, has a projection 28 that provides a bearing pin 29. The bearing pin 29 corresponds to the bearing eye 27 of the first joint element 23. Fig. 13 shows the dismantled position, whereas Fig. 14 The assembled position is shown. As can be seen from the assembled position after Fig. 14 As a result, the bearing pin 28 of a second joint element 24 engages in the corresponding bearing eye 27 of the corresponding first joint element 23. Due to this design, the hinge strip 14 is rotatably pivotable on the base body 13.

[0052] For simplified assembly, each bearing journal 29 has a chamfered end face 31, which simplifies the insertion of a bearing journal 29 into the corresponding bearing eye 27 in the assembly direction, as shown in Fig. 13As shown, in the illustrated embodiment, two adjacent joint devices 25 are provided, wherein the two bearing pins 29 of these two joint devices 25 define the axis of rotation 34 around which, in use, the folding bar 14 can pivot relative to the base body 13, as is also the case with the Figures 10, 12 and 17 can be seen from this.

[0053] To further simplify assembly, each bearing eye 27 is at least partially surrounded on its circumference by a stop edge 30. This stop edge 30 ensures that, during assembly, the corresponding bearing pin 29 can be threaded in and that it is not guided past the bearing eye 27.

[0054] A particular advantage of the embodiment according to the invention is that the joint elements 23 and 24 of a joint assembly 25 each provide stop devices, namely a first stop device on the one hand and a second stop device on the other, which define the two operating positions of the folding strip 14 in relation to the base body 13. Thus, the first stop device provided by the joint elements 23 and 24 defines the first operating position, and the second stop device provided by the joint elements 23 and 24 defines the second operating position. This relationship becomes particularly clear from the illustrations in the Figures 18 and 19 as well as 24 and 25.

[0055] The first hinge element 23 has a projection 26 which carries a cam 33 on the hinge side. In its intended use, this cam interacts with a stop surface 32 provided by the second hinge element. Together, the cam 33 and the associated stop surface 32 form the first stop device. This allows Fig. 24 recognize. In this position, the folding strip 14 is in its first operating position, which is defined by the fact that the stop surface 32 of the second joint element 24 rests against the associated cam 33 of the first joint element 23.

[0056] The second operating position of the folding strip 14 is in Fig. 25shown. In this second operating position, a thickening 35 provided by the extension 28 of the second hinge element 24 rests against a corresponding stop surface 36 of the first hinge element 23. Together, the thickening 35 and the corresponding stop surface 36 form the second stop device. Thus, as soon as the thickening 35 comes into contact with the stop surface 36 in the manner already described, the second operating position of the hinge strip 14 is reached.

[0057] The aforementioned stop devices are of a particularly simple design, as they are an integral part of the associated joint elements 23 and 24 of a joint assembly 25. Furthermore, this design enables the customer to reliably locate these two operating positions at all times.

[0058] To improve the stability of the joint assembly 25 under tensile load, the invention further provides that the extensions 26 and 28 of the associated joint elements 23 and 24 are designed obliquely to the assembly direction, i.e., at an angle to the axis of rotation 34 that deviates from 90°, as shown. Fig. 17 This can be seen.

[0059] In order not to impair the rotational pivotability, such an inclined alignment of the extensions 26 and 28 requires increased axial play, i.e., a spacing between the two extensions 26 and 28 in the direction of the axis of rotation 34. In this context, the following results from Fig. 17, that a resulting counterclockwise torque acts when the joint assembly 25 is subjected to a tensile load in the direction shown. In this case, the extensions 26 and 28 deform relative to each other, whereby disengagement, i.e., the bearing journal 29 being moved out of the associated bearing eye 27, is reliably prevented.

[0060] The dishwashing tray 12 according to the invention further has a locking device 37, as can be seen in particular from the Figures 20 to 23 The locking device 37 serves to hold the folding bar 14 in position, either in its first operating position according to Fig. 24 or in their second position of use according to Fig. 25 .

[0061] The locking device 37 has a cam rib 38 on one side and a locking cam 40 on the other. The cam rib 38 is provided by the first joint element 23, whereas the second joint element 24 has the associated locking cam 40. As can be seen in particular, Fig. 23 In this context, it can be seen that the cam rib 38 is equipped on the locking cam side with a recess 39 into which the locking cam 40 comes to lie in the first operating position of the folding bar 14, as shown in Fig. 22 is shown.

[0062] How a synthesis of Figures 18 to 21As can be further seen, the cam rib 38 of a locking device 37 is arranged as far away as possible from the joint devices 25 in the axial direction of the axis of rotation 34. A cam rib 38 extends beyond the axis of rotation 34 in the direction of the hinged bar 14 and has a circular contour around the axis of rotation 34 at its end. The locking cam 40 is provided in the bisector of the angle between the two end positions, i.e., the first operating position on the one hand and the second operating position on the other. This cam rests against the cam rib 38 and thus generates resistance relative to the cam rib 38 when the hinged bar 14 is rotated. The spring effect, which is generated by the maximum possible axial distance to the joint devices 25, allows the hinged bar 14 to be adjusted, resulting in bistability between the two operating positions.As a result, the folding strip 14 is fixed in its position after assuming one of the two operating positions, thus reliably preventing an unintentional pivoting of a folding strip 14 from a first operating position to a second operating position and vice versa.

[0063] A second embodiment of the locking device 37 provided according to the invention, viewed together, shows the Figures 63 to 76 According to this embodiment, neither a cam rib 38 nor a detent cam 40 is used. Instead, a detent spring 62 is provided, one for each detent device 37, as can be seen from the illustration. Fig. 63 This results in a total of two locking devices 37 according to the invention being provided.

[0064] As a synthesis of especially the Figures 64 to 67As can be seen, a detent spring 62 has a bearing pin 63 on the base body side and two bearing pins 64 on the hinge side. The bearing pin 63 is arranged axially between the two bearing pins 64.

[0065] For the arrangement of the detent spring 62 on the base body 13 on the one hand and on the hinge strip 14 on the other hand, corresponding bearing pin receptacles 65 and 66 are provided, as shown in the Figures 66 and 67 This can be seen. In the fully assembled state, the bearing pin 63 engages in the bearing pin receptacle 65 of the base body 13, and each bearing pin receptacle 66 of the hinged strip 14 receives a corresponding bearing pin 64.

[0066] The bearing journal 63 defines a first axis of rotation and the two aligned bearing journals 64 define a second axis of rotation, as shown. Fig. 66 as well as a summary of the Figures 72, 74 and 76This can be seen. The axes of rotation defined by the bearing journals 63 and 64 are arranged parallel to each other, but axially spaced apart. This relationship becomes particularly clear from a comparison of the Figure 66 , 72, 74 and 76 .

[0067] As explained above, hinge mechanisms 25, which define a common axis of rotation 34, serve to rotate and pivot the folding strip 14 on the base body 13. The folding strip 14 can be pivoted about this axis of rotation 34 relative to the base body 13. This relationship is also described in the Figures 71 to 76 depicted. The following show Figures 71 and 72 a first use position of the folding strip 14, which Figures 73 and 74 a middle position of the folding bar 14 and the Figures 75 and 76 a second operating position of the folding strip 14.

[0068] In the middle position of the folding bar 14 according to the Figures 73 and 74The pivot axis 34 and the pivot axes provided by the bearing journals 63 and 64 are aligned. In the first operating position according to the Figures 71 and 72 Starting from the center position, the axis of rotation defined by the bearing journals 64 is rotated counterclockwise upwards with respect to the plane of these figures. In this position, a first dead center position is defined. Therefore, a simple return to the neutral position without operator force is not possible.

[0069] A similar result can be obtained with regard to the second usage position according to the Figures 75 and 76 Starting from the center position, the folding bar 14 is pivoted clockwise to the left with respect to the drawing plane, according to this illustration, thereby achieving a second dead position. From this position, the folding bar 14 can also be pivoted back to the center position without any force being applied by the user. Figures 73 and 74 not take place.

[0070] As a review of the previously explained figures shows, the axes of rotation provided by the bearing journals 63 and 64 are chosen such that the angle bisector between the starting and end positions, that is, between the first operating position according to the Figures 71 and 72 and second position of use according to the Figures 75 and 76 A neutral position is created in which the axis of rotation provided by the bearing journal 63 lies on the line between the axis of rotation 34 and the axis of rotation defined by the second bearing journal 64, thus maximally deforming or bending the detent spring 62. Due to this deformation of the detent spring 62, a force is generated whose effective torque, with respect to the axis of rotation 34, changes direction after rotation through the neutral position.

[0071] The embodiment described above is particularly distinguished by its low wear. The locking spring 62 is made of a flexible yet durable plastic material, so that repeated pivoting of the hinged bar 14 relative to the base body 13 can be carried out with comparatively low wear on the locking spring 62. A further advantage over the first embodiment is that the locking spring 62 is a separate component from the base body 13 and the hinged bar 14, which can be easily replaced if necessary. This further increases the operational reliability of the dishwashing support 12 according to the invention. The locking spring 62 also securely fixes the hinged bar 14 in both the first and second operating positions relative to the base body 13, as described above.Unintentional pivoting of the folding bar 14 from the first operating position to the second operating position and vice versa is thus reliably avoided.

[0072] The dishwashing tray 12 can also be removed from a usage position according to the Figures 2 and 3 into a non-use position, for example according to the Figures 6 and 7 The dishwashing tray 12 is secured in position both in use and in the non-use position, for which purpose a positioning device 41 is provided according to the invention. In the illustrated embodiment, two positioning devices 41 are provided, as shown in the exploded view according to Fig. 8 This can be seen. The positioning device 41 and the base body 13 of the dishwashing tray 12 are preferably made of plastic in one piece.

[0073] The function and structure of a positioning device 41 according to the invention become apparent in particular from a combination of theFigures 26 to 44 , which show a first embodiment. Figures 45 to 62 a second embodiment can be identified. This embodiment is described in the Figures 26 to 44 preferred.

[0074] As can be seen in detail from the figures, the dishwashing support 12 has a base body 13 which has a positioning device 41 that interacts with a counter contour 42 on the dishwashing basket side. This positioning device 41 is designed for a rotatable and movable arrangement of the base body 13 on the dishwashing basket 11 and is configured to move the base body 13 relative to the dishwashing basket 11 from a working position to a non-working position and vice versa.

[0075] For this purpose, the positioning device 41 has bearing cams 47 that interact with the counter contour 42 of the washing basket 11 and provide aligned bearing recesses 48 along the axis of rotation 34. This relationship is particularly evident from the Figures 29 to 35recognize, whereby the Figures 29 and 30 a dishwashing tray 12 that has not yet been installed and the Figures 31 to 35 a fully assembled dishwashing tray 12 can be identified.

[0076] The bearing recesses 48 are designed such that, in the operating position of the base body 13, they prevent any movement of the base body in the vertical direction 50 of the dishwashing basket 11. In this position, as it is, for example, in Fig. 32 As shown, only a rotational movement of the dishwashing support 12 is permitted. However, movement of the dishwashing support 12 in the vertical direction 50 is prevented.

[0077] For this purpose, the storage recesses 48 are equipped with an undercut effective in the operating position of the base body 13 in the height direction 50 of the dishwashing basket 11. InIn the operating position, the bearing recesses 48 each partially engage a wire extension 45 of a wire bracket 43, as will be described in more detail below. The undercut is provided by an elastically pivotable lever 49 of the bearing cam 47, which lever 49 can pivot during assembly and disassembly, allowing the corresponding wire extension 45 to engage behind the bearing recess 48. This relationship is particularly evident from a comparison of the Figures 30 and 32 recognizable.

[0078] Fig. 30Figure 1 shows the unassembled state of a dishwashing tray 12 according to the invention. In this position, the dishwashing tray 12 rests on both sides on a U-shaped wire bracket 43 of the counter contour 42, formed from a base wire 44 and two wire extensions 45 and 46. The dishwashing tray 12 is supported on the hinge side by the wire extension 46 of the wire bracket 43. The other wire extension 45 of the wire bracket 43 interacts with the lever 49 as previously described. If, for the purpose of assembly, the base body 13 of the dishwashing tray 12 is pressed downwards with respect to the vertical direction 50, the lever 49 bends so that the rear wire extension 45 can snap into the bearing recess 48 provided by the bearing cam 47, which position is Fig. 32As shown. In this position, a movement of the washing material support 12 in the vertical direction 50 is no longer possible, since the bearing recess 48 with its undercut engages behind the associated wire extension 45 of the wire bracket 43.

[0079] To secure the position of the dishwashing support 12 in the operating position in the width direction 54 ( Fig. 37 The positioning device 41 also has a support rib 52. In combination with the bearing cam 47, this rib prevents the base body 13 from moving in the width direction 54 when in its operating position. The support rib 52 has a centering recess 53, as can be seen in particular from the illustration below. Fig. 28 This results in a centering recess 53 in which, in the operating position of the dish support 12, a wire 59 of the opposite contour 42, provided by the dish basket 11, comes to rest, as shown by the Figures 37 and 38The support rib 52 is arranged on the dishwashing support 12 in such a way that a dishwashing item lying against the hinged strip 14, as shown in Fig. 5 As indicated, a counter-moment is generated, which forces the dishwashing tray 12 into the operating position. This further prevents it from unintentionally moving into the non-operating position.

[0080] As can be seen from the aforementioned context, the dishwashing tray is secured in its operating position both vertically (50) and horizontally (54). Furthermore, it is secured in the depth direction (55). Fig. 38 ) provided for which purpose corresponding guide tabs 56 and 57 serve, whereby such securing in the depth direction 55 takes place not only in the use position, but also in the non-use position of the dishwashing support 12.

[0081] The guide tabs 56 and 57 result in particular from a combination of the Figures 34 and 35 , specifically for those relating to the drawing plane according to Fig. 33 both the left positioning device 41 and the right positioning device 41.

[0082] The first guide tab 56 provided for each positioning device 41 interacts with the wire extension 45 of the associated wire bracket 43. The first guide tab 56 rests against the wire extension 45 at its end face. In combination, the two positioning devices 41 thus prevent any displacement of the dish support 12 in the depth direction of the dish basket 11. This is because the respective wire extensions 45 rest against the corresponding guide tab 56, which prevents any movement.

[0083] In the event of a transfer of the dishwashing tray 12 from a working position to a non-working position according to Fig. 7First, the dishwashing tray 12 rotates around the axis of rotation 51. This is shown by a summary of the Figures 36 to 41 The axis of rotation 51 is defined by the aligned wire extensions 45 of the two wire loops 43. As soon as the pivoted position according to Fig. 40 Once this point is reached, a wire extension 45 is released from the respective bearing recess 48. A downward movement of the twisted wash-product support 12 in the vertical direction 50 is now permitted, as can be seen from a summary of the Figures 42 to 44 This can be seen.

[0084] To achieve the pivoted position according to Fig. 40 The dish support 12 is to be swivelled to its stop. For this purpose, each positioning device 41 has a rotation stop 58 ( Fig. 34 ). As soon as this anti-rotation stop 58, in the event of rotation, contacts the corresponding wire 60 of the counter contour 42 ( Fig. 40Once the rotational movement is complete, the dish support can be moved in the vertical direction 50 with reference to the drawing plane, for example, to Fig. 40 proceed downwards.

[0085] During the aforementioned twisting movement, the second guide tab 57 comes into contact with the corresponding wire 60 of the counter contour 42. This also shows Fig. 40In this state, when the dishwashing support 12 is not yet in a forward position but only rotated, both the guide tabs 56 with the associated wire extensions 65 and the second guide tabs 57 with the associated wire 60 are in contact. As a result of the dishwashing support 12 now moving downwards in the vertical direction 50 to move into the out-of-use position, the first guide tabs 56 lose contact with the wire extensions 45. The second guide tabs 57, however, remain in contact with the associated wire 60, so that the dishwashing support 12 is secured in the depth direction 55 even in the out-of-use position and during the movement into the use position.

[0086] The particular advantage of the embodiment according to the invention lies in the fact that the two positioning devices 41 ensure that the dishwashing support 12 is secured in the desired position at all times, whether in the operating position or the non-operating position. By design, the dishwashing support 12 is automatically secured in the depth direction 55 by the fact that, during the transfer of the dishwashing support 12 from the operating position to the non-operating position and vice versa, the associated guide tabs are automatically brought into engagement with the counter contour 42. Each positioning device 41 is preferably formed integrally with the base body 13 of the dishwashing support 12, which enables a simple design and is also wear-resistant and durable.

[0087] An alternative embodiment is shown in the Figures 45 to 62According to this alternative embodiment, an additional wire 61 is provided for the conventionally designed dishwashing basket 11, which performs the aforementioned functionalities of the guide wire on the one hand and the wire bracket 43 on the other. This has the advantage that a guide support in the depth direction of the dishwashing support 12 is equally possible with a single tab, which thus combines the first guide tab 56 and the second guide tab 57 equally, as is particularly evident from a review of the Figures 48 to 56 This can be seen.

[0088] According to the second embodiment, the vertical guide section of the wire 61 is not part of the dishwashing basket 11, but rather part of the wire bracket 43 attached to it. Thus, in the second embodiment, the wire 61 and the wire bracket 43 are formed as a single piece. This design provides internal guidance, which ensures that the dishwashing support 12 is secured against movement in the depth direction, both in the operating position and in the non-operating position. Furthermore, this construction allows for a comparatively long guide tab in the longitudinal direction, which provides additional stability during movement.

[0089] The second embodiment also offers a comparatively simple assembly, as is the case with the Figures 51 to 56This reveals that the dishwashing support 12 simply needs to be positioned vertically above the wire 61 and can be moved downwards in a vertical direction beyond the locking mechanism 47. Tilting is prevented by the guide tabs 56 and 57. Furthermore, no special threading is required, so the assembly described above can advantageously be automated. Reference sign
