Description

Technical Field

[0001] This utility model relates to an arrangement structure with a dishwashing basket, on which a pull-out guide is fixedly attached, and also to a dishwasher including such an arrangement structure. Background Technology

[0002] When fully loaded, the dish rack can have a high total weight, which must be supported by pull-out guides on both sides of the rack. Therefore, securing the dish rack to the running track of the pull-out guides is crucial.

[0003] As a common arrangement, such as that known from DE 20 2006 003 556 U1, the running track has two rows of overlapping clamp-like hooks, in which two overlapping, horizontally extending wires of the dishwashing basket can be secured. The wires of the dishwashing basket form a holding device for the basket. Although this design has proven successful in itself, further optimization is needed in securing the pull-out guide to the dishwashing basket. Summary of the Invention

[0004] Therefore, the problem to be solved by this utility model is to create a structurally optimized arrangement that achieves good fixation between the dishwashing basket and the pull-out guide track in a simple way.

[0005] The problem is solved by an arrangement structure according to one aspect of the invention.

[0006] Therefore, an arrangement is provided comprising a dish basket, at least one dish basket support, and at least one pull-out guide fixed to the dish basket support, the at least one pull-out guide having two or more tracks mounted linearly displaced relative to each other, the tracks including at least one running track and at least one main track, wherein the running track includes at least one or more retaining hooks, each retaining hook being integrally formed with the running track and used to secure the running track of the pull-out guide to the dish basket support; and wherein the at least one or more retaining hooks includes at least one reinforcing rib that reinforces the retaining hook in a simple and advantageous manner. In this way, a structurally optimized design is created that allows the pull-out guide to be secured to the dish basket in a simple and stable manner.

[0007] The dish rack support can be integrated with the dish rack as a single piece, or it can be designed as a separate component that is fixed to the dish rack.

[0008] According to an advantageous alternative embodiment, the invention can be further advantageously improved due to ease of manufacture: the corresponding fixing hook of the running track is made of a metal plate, wherein the corresponding fixing hook is cut from the metal plate and connected to the running track in one piece at a connecting end, wherein the corresponding fixing hook preferably has a first bend, an adjacent connecting leg, a second bend, and a support leg in the region at the connecting end. According to another advantageous alternative embodiment, the dimensions of the first and second bends can be designed such that the support leg of the fixing hook is substantially parallel to the upper running track web in the vertical direction of the running track in the installed state. Such a fixing hook is simple and inexpensive to manufacture, but is very stable due to at least one reinforcing rib. Alternatively, the dimensions of the first and second bends can be designed such that the support leg is substantially parallel to the lateral running track web in the installed state. This allows the invention to also be used with conventional ball bearing slides.

[0009] According to another advantageous alternative embodiment, a further advantageous and unique feature of this invention is that the support leg of the fixing hook may include an insertion ramp, which simplifies the assembly process.

[0010] According to another advantageous alternative embodiment, a further advantageous and unique feature of this invention is that the reinforcing ribs can be formed by an embossing process. In this way, the reinforcing ribs can be quickly and easily formed on the fixing hook during the manufacturing process.

[0011] According to another advantageous alternative embodiment, a further advantageous and unique feature of this invention is that the reinforcing rib can be formed in the region of the first bend. The reinforcing rib has a particularly advantageous effect in this location.

[0012] According to another advantageous alternative embodiment, a further advantageous and unique feature of this invention is that the reinforcing rib can extend beyond the first bend into the area of ​​the running track web and the connecting leg, and the reinforcing rib protrudes from the inside out relative to the running track web. The reinforcing rib also has a particularly advantageous effect in this manner.

[0013] According to another advantageous alternative embodiment, a further advantageous and unique feature of this invention is that the reinforcing rib can be slightly narrower than the fixing hook, and is formed within the fixing hook and approximately centrally. In particular, according to this improvement, the fixing hook also achieves excellent stability.

[0014] According to another advantageous alternative embodiment, the bend can be specified to extend at an angle α of 30° to 60° relative to the plane of the running track web. This is because the stiffeners have a particularly advantageous reinforcing effect within this range of the bend.

[0015] According to another advantageous alternative embodiment, a plurality of retaining hooks may be oriented in the same direction, and each of the plurality of retaining hooks passes through a lateral groove or through-hole in the dish rack holder and is clamped onto the support surface of the dish rack holder via its bottom side. This allows the pull-out guide to be quickly and easily installed onto the dish rack holder.

[0016] According to another variant, the corresponding fixing hook can pass through the lateral groove or through hole of the dish rack bracket and be elastically installed into the groove of the support surface of the dish rack bracket in a snap-fit ​​manner through the bottom side of the support leg.

[0017] According to another advantageous alternative embodiment, the corresponding support surface of the dish rack bracket may have a reduced height or wall thickness in the support surface area. This also allows the pull-out guide to be quickly and easily installed onto the dish rack bracket.

[0018] According to another advantageous alternative embodiment, the running track may include at least one preferably wedge-shaped protrusion on its top side spaced apart from at least one fixing hook, the protrusion being placed in a corresponding groove in the dish rack support, thereby advantageously and simply forming additional anti-displacement protection between the dish rack support and the running track.

[0019] According to another advantageous alternative embodiment, the running track can be defined as a non-circumferentially closed profile formed by bending a metal plate into the shape of a track, with openings at both ends, and a plug can be provided at at least one open end, the plug including a closed end for closing the running track.

[0020] According to another advantageous alternative embodiment, the plug at the closed end may include one or more clamping protrusions projecting to one side, wherein the plug is preferably clamped and fixed to the end of the running track by one of the clamping protrusions, and the clamping force of the other clamping protrusion may be slightly less than that of the clamping protrusion in the running track. When the corresponding pull-out guides are pushed together, the other clamping protrusion engages with the corresponding open end of the main track in a slightly clamping manner, thereby also advantageously closing the open end.

[0021] According to another advantageous alternative embodiment, it can be advantageously specified that one or more main track supports can be provided for each pull-out guide. These supports can be offset in the direction of the corresponding main track, thereby providing a very good and secure hold against the side wall of the dishwasher. According to another advantageous alternative embodiment, it can be advantageously and conveniently specified that the corresponding main track support may include: a plate-like portion that can be fixed to the inside of the corresponding side wall of the interior space; and a preferably channel-like receiving portion for the main track, in which the main track is preferably secured by a snap-fit ​​mechanism. This fixing method is simple and safe.

[0022] Preferably, one of the arrangement structures includes a dish basket, two dish basket supports, and a pull-out guide on each dish basket support.

[0023] According to the present invention, a dishwasher is also provided, having an interior space and an arrangement structure in which at least one aspect of the present invention is installed. Attached Figure Description

[0039] Figure 1 The interior space 1 of a dishwasher (not shown here) is illustrated. This interior space includes a base plate 11, a first side wall 12, a rear wall 13, a second side wall 14, a top wall (not shown here), and a hinged door formed herein as a flap 15. Figure 1 The middle flap 15 is in the open position.

[0040] Orientation is performed using a Cartesian coordinate system with X, Y, and Z axes.

[0041] Figure 1 An example of one of the possible multiple dish racks 2 is also shown. This dish rack 2 can be accessed via two pull-out guides 3 (see...). Figure 2 The internal space 1 is pulled in and out in the X direction (usually horizontal), and the pull-out guide 3 is indirectly fixed to the dish basket through the corresponding dish basket bracket 4.

[0042] exist Figure 2 An embodiment and arrangement of the pull-out guide 3 visible in the interior space 1 and the dish rack 2 will be described in detail below. Figure 2 The second pull-out guide 3, which is visible in the middle, can preferably be fastened to the other side of the dish rack 2 in the same manner.

[0043] The guide 3 can be pulled out and then secured to the inside of the side walls 12, 14 via one or more main track brackets 5.

[0044] Each pull-out guide 3 can (see in detail) Figure 6a , Figure 7a (See Figure 8) includes at least two, preferably three or more, telescopic tracks that are linearly displaced relative to each other, and these telescopic tracks further include at least one running track 6 and at least one main track 7. Preferably, an intermediate track 8 may also be provided between the running track 6 and the main track 7. Bearing devices, particularly ball bearing devices 9 (with ball bearing elements and corresponding ball bearing cages), may also be provided between tracks 6, 7, and 8, wherein tracks 6, 7, and 8 can telescopically displace relative to each other (see Figure 8).

[0045] The two main tracks 7 of the two pull-out guides 3 are fixed to the inner sides of the corresponding side walls 12 and 14, and the running tracks 6 of the two pull-out guides 3 are fastened to the dish rack bracket 4.

[0046] The dish rack support 4 can be formed as a single piece with the dish rack 2. However, it can also be designed as a separate component fixed to the dish rack 2. This fixing can be, for example, a snap-fit ​​type. For instance, one or more snap-fit ​​receptacles 41 can be formed on the dish rack support 4, into which the rod 21 of the dish rack 2 is inserted as a corresponding snap-fit ​​element (see [link]). Figure 3 ).

[0047] The running tracks 6 of the two pull-out guides 3 are secured to the dish rack bracket 4 by one or more fixing hooks 61 of the corresponding running tracks 6. In this example, the two fixing hooks are offset on the running tracks 6 in the X direction (see [link to example]). Figures 6a to 6cThe running track 6 (such as other tracks for pulling out the guide 3) can be formed by stamping / bending a sheet metal. It is simple and safe to form the retaining hook 61 as a single piece with the running track 6. For example, the corresponding retaining hook 61 is first stamped out of the sheet metal of the running track in a tongue-like form on three sides as a web, wherein the tongue-shaped web is formed during stamping, and this tongue-shaped web remains connected to the rest of the running track at the connecting end 611, and then preferably bent at least twice. In this way, the retaining hook 61 includes a first bend 612 offset from the running track 6, an adjacent support leg 613, a second bend 614 again opposite the running track 6, and a support leg 615.

[0048] The dimensions of the first and second bends 612, 614 are preferably designed such that the support leg 615 can extend substantially parallel to the upper running track web 60 from which the running track 6 is cut in the installed state. In an alternative variant not shown, the support leg can extend substantially parallel to the lateral running track web. The support leg 615 can be substantially bent at its outermost end region, thereby forming the insertion guide ramp 6151 of the retaining hook 61.

[0049] Preferably, at least one reinforcing rib 616 is formed on at least one or more phases of the corresponding fixing hook 61 (see...). Figures 6a to 6c The reinforcing rib 616 can be formed by an embossing process. For example, it can be formed in the region of the bend 612 of the connection end 611 between the running track 6 and the fixing hook 61. The reinforcing rib 616 can extend beyond the bend 612 and enter the corresponding regions of the running track web 60 and the connecting leg 613. The reinforcing rib 616 can be pressed into the fixing hook 61, so that it protrudes from the inside out relative to the running track web 60 (protruding outward in the Z direction in the installed state). The width of the reinforcing rib 616 is preferably slightly smaller than the width of the web forming the fixing hook 61, and is formed approximately centrally in the fixing hook (here relative to the Y direction). The reinforcing rib 616 is particularly advantageous if the bend 612 is not perfectly right-angled, but extends at an angle α of 30° to 60° relative to the plane of the running track web 60, because the position of the connecting leg 613 is well stabilized and the entire fixing hook 61 is well reinforced. The reinforcing rib 616 can exist only on one or more fixing hooks 61 of the corresponding pull-out guide 6.

[0050] The retaining hooks 61 are advantageously oriented in the same direction (here, the X direction) or open in the same direction (here, the -X direction). The corresponding retaining hooks 61 pass through the lateral grooves or through-holes 42 of the dish rack support 4 and are clamped onto the corresponding support surface 43 of the dish rack support 4 via the underside of its support leg 615 (see, for example...). Figure 4It may have a reduced height or wall thickness in the support surface 43 region. The curved shape of the fixing hook 61 advantageously forms at least one clamping part (Klemmung) of the dish rack support 4 between the support leg 615 and the top side (running track web 60) of the running track 6.

[0051] As an additional protection, the running track 6 may include at least one preferably wedge-shaped protrusion 62 in the region of the running track web 60 spaced apart from at least one retaining hook 61 on its top side. This protrusion may be located in an additional groove 44 of the dish rack support 4 to form an anti-displacement protection, thereby additionally preventing the retaining hook 61 or the running track from accidentally loosening from the dish rack support 4 (see example...). Figure 5 ).

[0052] Before the running track 6 and the dish rack support 4 have been displaced relative to each other in the X direction, the corresponding retaining hook 61 can first be pushed through the corresponding through hole 42 of the dish rack support in a direction perpendicular to it, until the retaining hook portion 615 (see...) Figure 6a , Figure 6b and Figure 6c It is clamped onto the support surface 43 of the dish rack bracket 4 (see...). Figure 3 , Figure 4 and Figure 5 ).

[0053] The running track 6 is preferably a non-circumferentially closed profile formed by bending a metal plate into the shape of a track, and has openings at both ends 64 and 65. A plug 63 may be provided at at least one of these open ends 65 for closing the running track 6 (see...). Figure 9a , Figure 9b , Figure 9c and Figures 10a to 10d The corresponding plug 63 may include a closed end 631 and one or more clamping protrusions 632, 633 protruding to one side.

[0054] The plug 63 is preferably secured to the end 65 of the running track 6 by clamping one of the clamping protrusions 632. Preferably, the clamping force of the other clamping protrusion 633 can be slightly lower than that of the clamping protrusion 632, and when the pull-out guide 3 is pushed together, the clamping protrusion 633 engages the corresponding open end of the main track 7 in a slightly clamping manner. Figure 9c In this state, the corresponding opening end is closed and can be detachably engaged by pulling out the dish rack 2. The clamping protrusions 632 and 633 can also be directly connected to each other via a web or the like.

[0055] One or more main track brackets 5 are provided for each pull-out guide 3. These brackets can be offset in the direction of the corresponding main track 7 (see...). Figure 3 , Figure 4 , Figure 5 See also Figure 11 , Figure 12 (Figures 13 and 14). Each of the main track supports 5 may include a plate-like portion 51 that can be fastened to the inner side of the corresponding sidewall 12, 14 of the interior space, for example, by one or more screws (not shown here). For example, a channel-like receiving portion 52 may be molded on the plate-like portion 51. This receiving portion can be used to receive the main track 7, which can preferably be inserted into the receiving portion from above and can be fixed therein, for example, by means of a snap-fit. The main track 7 can also be fixed to the corresponding main track support 5 in the X direction by one or more corresponding snap-fit ​​members 53 and snap-fit ​​matching members 71, for example, which can be formed as one or more snap-fit ​​hooks and grooves, and which can also be offset in the pull-out direction, so that it cannot be displaced (see Figure 14). Figures 13a to 13c ).
