Abstract

The dish support bars (8b) pivot on a support rod (9b) to rest in a using position by turning a lever (11) or in a dormant position clear of wash items. The formation of the bar provides a spring effect to hold the bar in the selected position.

Description

The invention relates to a pivotable in the crockery basket arranged in accordance with a dishwasher the preamble of claim 1.

It is known to plant elements, preferably a plate rake, to be arranged pivotably in a crockery basket. The Pivoting mainly takes place approximately horizontal non-use position in an approximate vertical position of use. In the position of use, the contact element serves preferably the plate rake, the support of Washware, preferably from plates, in the crockery basket can be set. In a known manner is in baskets to determine the contact element in the position of use on the back a fixing element, e.g. B. a U-shaped hook provided, in which the contact element is suspended. The disadvantage of the prior art is the unwieldy garbage Hook the contact element out of or into the position of use. Another particular disadvantage is that the Contact element in the position of use in its intended fixing elements wobbles around, which is particularly annoying becomes.

Based on this state of the art, it is therefore a task the invention to propose an investment element, which pivotable in the dishwasher basket pivotable in the dishwasher basket can be arranged and the disadvantages mentioned above are not having.

The object is achieved with the characteristic Features of claim 1 solved.

According to claim 1, a crockery basket of a dishwasher at least one investment element, which at least comprises a base staff and an investment staff. That is preferable Includes system element designed as a plate rake a base rod and several spikes as contact rods. The spines are used in the dishes basket set plates or other wash ware as an attachment and thus as a support option. The base bar is at least partly over the length or width of the crockery basket arranged, the spines connected to it from Stand the base rod at an angle. The pivoting of the Plate raking is done around the axis of the base bar, the especially coupled to the wire rack of the crockery basket is. The non-use position of the plate rake corresponds a position close to the basket floor, preferably horizontal Position, which is an angle of 0 ° or 180 ° in the coordinate system equivalent. When the plate rake is not in use large items are in the crockery basket, e.g. Pots and pans, adjustable. The plate rake is in principle from the non-use position to the use position and reversely pivotable. The pivoting from the position of use, which is approximately an angle of 90 ° in the coordinate system corresponds and preferred the vertical position includes, can thus generally to the right or on the left, whereby the plate rake is flipped to the right the angular range of the first quadrant of the coordinate system in a closed interval from 90 ° to 0 ° and moving the plate rake to the left of the second Quadrants of the coordinate system in the closed interval sweeps from 90 ° to 180 °. The base of the Contact element is designed as a spring element or on the contact element acts at least one spring element in such a way that the contact element is tensioned in the position of use. In order to prevent the investment element from being assigned to it Swivel range, i.e. an angular range between the position of use and non-use position, which is therefore either between 90 ° and 0 ° or 90 ° and 180 °, leaves automatically, at least one stop is provided. In the case, that both a pivoting range of 0 ° to 90 ° and 90 ° to 180 ° are provided comprises at least two stops in the position of use. Since that In principle, the plant element also when it is not in use can escape from its pivoting range is preferred also a stop for the limitation when not in use, hereinafter referred to as stop N, arranged. In the non-use position can be used as a stop N existing floor of the crockery basket can be used. On Another stop for fixing the contact element in The position of use is referred to below as stop G.

Due to the stress state of the contact element in at least the contact element is approximately vertical naturally strives to maintain a tension-free state take. However, this is provided by an intended stop G prevented in the position of use. The tensioned system element and the additional support effect of the stop G position for the contact element in the position of use almost free of play and thus create something annoying Remedy.

In its swiveling range between non-use and The plant element passes through the position of use differently strong states of tension, a defined angle between 90 ° and 0 ° or 90 ° and 180 ° corresponds to a stress situation of the contact element, in which the tension of the contact element has a maximum. The stress situation is due to the type of voltage generation on the contact element freely definable.

A voltage maximum in the swivel range has the advantage that the contact element derives from its stress situation automatically in the use position or in the non-use position moves, which creates a kind of snap effect, so that a cumbersome and unwieldy lifting into a fixing device is not necessary. As already described above, becomes the automatic further movement of the contact element from use or non-use position by stops G or N prevented. The natural striving of the investment element in its tension-free rest position, that of the stress situation opposite and therefore below the basket floor is in any case by the one used as the stop N. Basket bottom prevented. This is the contact element even when not in use, excited to see what happens when adjusting larger items to be washed down due to less noise as a result Rattling the plant element against that Items to be washed while the dishwasher is in operation or advantageous when placing the dishes in the crockery basket affects and increases the utility value.

The voltage acting on the contact element from the outside becomes particularly preferably mainly on the base rod Recording elements exercised. A voltage generation through Exercise this on other parts of the investment element, e.g. B. on the spikes of the plate rake or other plant bars is possible, too. If spring elements are arranged, this acts the tension mainly on this, the tension effect from the outside onto the base rod is much less.

The base rod is particularly advantageous in at least one End piece bent, the bent end piece doing the function of the stop G can exert a striving for the contact element prevented from its position of use by against the basket floor or other struts of the crockery basket encounters. Or at one end of the base bar is a crank cranked, which does not align the base rod and their orientation the stress or rest position of the Determines investment element.

In a preferred embodiment, the base rod is predominantly d. H. between its two end pieces, symmetrical bent and has a bent at one end piece Stop G on. In a further preferred embodiment there is also a stop G at one end piece bent and a crank is cranked at the other end piece.

If the stop G, which is an automatic movement of the Investment element, the following in its nature as a snap or snapping away movement from which prevents vertical use, not as in a preferred Embodiment molded onto the base rod in the end piece, this stop G is separated from the base bar provided another place of the crockery basket. Is the Stop G on the base rod is arranged as a counter stop for this by appropriate design either the axles of the wheels or a wire of the side walls or the bottom of the crockery basket. Is this not possible, i.e. the stop G is an additional element on Dish basket arranged, then serve as a counterstop Base rod or at least a spike or other element of the investment element.

The one to be clamped on the crockery basket is particularly preferred Base bar before its storage in this already by appropriate Deformation into an internal state of stress offset, i.e. biased. The base bar is in front of it Storage in the crockery basket in any case not as a straight one Wire, but e.g. arched.

In a further preferred embodiment, at least act three receiving elements and / or spring elements, the non-aligned in a clamped with the base rod Level are arranged on the non-straight and under inner Tensions stand and are the cause the overall state of stress acting on the base rod, which the movement of the contact element with the above Snap effect enables. The receiving elements are, for example as hook-like depressions or depressions a strut of the crockery basket or as a separately arranged Brackets and / or spring elements executed. The spring elements are designed as tongues, for example. Free deformable wires that are several of the above-mentioned receiving elements and / or absorb spring elements and are with attached to the crockery basket so that they e.g. on different Investment elements work. Are the three recording elements or spring elements not in alignment, so lay these receiving and / or spring elements, caused by the choice of their arrangement, the stress level of the base bar and thus the location of its maximum voltage.

The determination of the stress situation continues as before described above in the angular range of the pivoting. Becomes for example, an investment element from the position of use swiveled to the right into the non-use position, so it is Stress situation with an angle between 0 ° and 90 ° set, it being particularly advantageous if the Stress situation at least the approximately right angle divides between use and non-use position at 45 ° or the angle between the non-use and stress position is chosen larger than 45 ° because of the snap effect the shorter the distance, the greater the closer the stress situation is is due to the position of use.

To put tension on the non-straight base rod from the outside apply and the base rod can be pivoted at the same time to be stored, at least three arranged receiving and / or Spring elements are not aligned so that alternating, pressing - holding - pressing or arranged to be holding - pressing - holding d. H. a holding receiving or spring element acts as a support Pressure point on the base rod from below during the adjacent pressing receiving and / or spring elements press on it from above and thus as the upper pressure points Act.

In the case of a pressing - holding - pressing arrangement the receiving and / or spring elements are the most pressing Receiving and / or spring elements conveniently as a fixed bearing designed for an X and Y coordinate, where the X coordinate in the direction of the horizontal, the Y coordinate towards the vertical and the Z coordinate points in the direction of the pivot axis of the base rod, wherein the latter is free. The receiving camp is then as halfless bearing designed, this is a movement of the Contact element in the Y direction, in one orientation, i.e. prevented above or below the crockery basket bottom.

In a preferred, because simple embodiment are two bearings as fixed bearings and one bearing as semi-loose Bearing executed as a semi-free bearing can be a cross or Longitudinal strut of the crockery basket base serve while for the fixed bearing receiving elements e.g. arranged in the form of brackets are.

In one embodiment, the base bar can at least a trough stored in the crockery basket and also a hold-down be provided so that trough and hold-down for the base rod form a fixed bearing.

A spring element acting as a fixed bearing on the base rod is in a further preferred embodiment as a tongue designed. It is also advantageous that spring elements and / or receiving elements by suitable shaping e.g. formed from a wire and arranged in the crockery basket are that several receiving elements arranged on the wire on different base rods from several planned system elements, e.g. Plate rake, work at the same time. So is it constructively e.g. particularly easy at the ends of a Wire piece to arrange a receiving element. on the other hand can be skilfully formed by Longitudinal struts of the crockery basket base to hold the and / or spring elements are molded so that additional Material expenditure remains limited to this.

In another preferred embodiment is on one End piece of a base bar cranked, so can on the crank above or below the bottom of the crockery basket a spring or receiving element act such that with the arrangement of two further receiving elements approximately in The height of the base of the crockery basket, in turn, is not stored in alignment and thus depending on the position of the crank is excited. Both those described above apply here Advantages and functional principles, as well as the conditions between use and non-use position and Stress and rest position and stress and use position and upper and lower pressure points exist stay.

The pivoting of the contact element and thus the plate rake from its non-use position to the use position as well as from the use position to the non-use position is done by manual intervention. From the above the result is that the force applied is sufficient in order to overcome the stress situation of the contact element, the contact element when the stress level is reached can be released and the contact element then automatically in the use or non-use position snaps, the preferred direction in which the contact element snaps, mainly by the trend-setting Type of manual intervention is determined.

Another embodiment of the fixation of the contact element in the position of use it is conceivable that the contact element in the position of use in a fixing element with at least a trough-shaped indentation snaps. The trough-shaped Indentation has the advantage that the two-sided Boundary areas of the trough the contact element as two stops G and thus next to the support point of a first Stop G, further support point for the contact element in Use position are present, which mainly to do so serve, a folding of the plate rake by a light, to prevent accidental bumping. The Muldenberg thus provides a in the use position for the contact element Kind of additional security threshold, whereby towards is to ensure that the stress situation is determined so that the contact element automatically in the position of use can snap. As an alternative embodiment conceivable to arrange two fixing elements and another Stop G stop.

The trough is particularly advantageous because of its low construction Effort, preferably in a basket existing element integrated, otherwise it must be separate be arranged as a fixing element.

In a further development of the invention is on the crockery basket at least one further stop Z is arranged. If this stop Z is arranged on the base rod, it can with a particular advantage that the Prevent the base rod in its free coordinate axis Z, by the stop Z against a strut of the crockery basket strikes. On the other hand, the stop Z through the contact element be realized in itself, so that e.g. the side each outer spike of the plate rake slipping out of the contact element by striking the outer Prevents spikes on the side walls of the crockery basket. Furthermore, the stop Z can be arranged accordingly next to the stop G, the position of the contact element in the position of use additionally stabilize in one point.

The stop Z can also be used as a special advantage Fastening device for immersing the wire base frame the basket in a plastic mixture for training be made of a plastic coating.

The fixed bearings of the base rod are preferably in the form of brackets or other elements of the crockery basket, e.g. wires with appropriate shapes for the storage of the base rod, executed, the wires being components at the same time the bottom of the crockery basket. The halfless camp and Spring elements are preferred by individual as mentioned above Struts formed the bottom of the crockery basket.

Both the brackets and the bearing elements to be provided, Spring elements, fixing elements or stops exist either made of plastic or like the crockery basket from one Plastic-coated wire base frame.

In Figure 1, a crockery basket 1 is not shown Dishwasher shown for the purpose of better Overview not complete and only with its for that Understanding of the invention essential components of the baskets 2, side walls 3, impellers 4, axis 5 of the Impellers 4, longitudinal struts 6, cross struts 7, longitudinal and Cross struts (6,7) form the crockery basket bottom and theirs Ends that are partially reshaped components of the side walls 3 are shown. As an investment element is a Plate rake 8 pivotably arranged in the crockery basket 1, this is in a non-use position, in which the plate rake 8a in the crockery basket 1 is folded down and consequently no plates, but rather large wash ware, e.g. Pots in the crockery basket 1 can be placed.

The plate rake 8 basically consists of a non-straight one Base rod 9 and several spines arranged on it 10, at a definable angle from the base bar 9 stand out, with individual adjacent spines 10 parallel lie to each other in such a way that they match the set Dishwashing in the position of use shown in FIG. 2 is a preferred position give. The plate rake 8a is in Fig. 1 in almost horizontal non-use position, being exemplary it is shown that different cross struts 6 as a stop N serve and prevent further movement of the plate rake 8a. At one end of the base rod 9.9a is a stop G 11 arranged. As intended, the G 11 stop exercises Non-use position does not stop its stop function. It In terms of design, attention is paid to the fact that the stop G 11 a pivoting of the plate rake 8 between horizontal non-use position and vertical use position not disabled.

The coordinate system 12 shown serves for reference the directions in the description.

Furthermore, three receiving elements 13a, 14a and 13b are close to the Dish rack bottom 2 provided. The plate rake 8, 8a-d is by arranging its base rod 9, 9a-d in the three Receiving elements 13a, 14a and 13b on the crockery basket base 2 pivoted and due to the non-aligned arrangement the receiving elements 13a, 14a, 13b stretched in an arc. The receiving elements 13a, 14a, 13b act with respect of the drawn coordinate system 12 for the base bar 9, 9a in the X and Y directions as a fixed bearing. In the X and Y directions change the pressure points of the neighboring recording elements each in one orientation. Here is a movement of the base rod 9a in the Y direction in orientation above the crockery basket bottom 2 mainly by the receiving element 14a prevents while in orientation a movement to and below the bottom of the crockery basket mainly by the receiving elements 13a and 13b, but the longitudinal and transverse struts (6,7) are also prevented. The Movement of the base rod 9 a in the X direction is as mentioned above with alternating orientation of the pressure point of the adjacent receiving elements 13a, 14a, 13b prevented. All three receiving elements 13a, 14a and 13b allow movement of the base rod 9 in the Z direction. The plate rake 8 However, can not slip through the side walls 3, because the the next 3 spikes 10 on the side wall. The receiving elements 13a, 14a and 13b shown are from Type holding - pressing - holding, with the receiving elements 13a and 13b support the base rod 9a while the receiving element 14a presses on the base rod 9a and thus alternately lower and upper pressure points on the Base rod 9a act. It follows from the above that for the tensioned state of the non-straight, prestressed base bar 9a the non-aligned arrangement of the receiving elements 13a, 14a and 13b is the cause. For understanding the invention is essential that during pivoting the plate rake 8 from the non-use position 8a in the position of use 8b, cf. Fig.2, different strong stresses are exerted on the base rod 9a-c or 9a-9d become. The base rod is in the non-use position shown 9a excited when moving the plate rake 9b in the position of use, cf. Fig.2, this is experienced by manual Initially, an increase in tension engaging in a Stress situation of the plate rake 9c, cf. Figure 3, reached a maximum. If the plate rake 9c in the stress position released, he can automatically in the position of use 9b move or snap and will here determined by the G 11 stop. In use position 9b has the tension of the base rod 9b compared to the stress position 9c reduced. The G 11 stop prevents a natural striving of the base rod 9 and thus the Plate rake 8 in a de-energized position 8d, cf. Fig. 4. The tensioned state of the base rod 9a-c and the support effect of the G 11 stop allow an almost play-free and thus wobble-free positioning of the base rod 9b and thus the plate rake 8b in the position of use.

Each piece of wire 19 also connects the holding receiving element 13a with a pressing receiving element 14b and a pressing receiving element 14a with a holding receiving element 13c in such a way that the examples indicated Receiving elements 14b, 13c and another one, not shown pressing receiving element to show the possibility to be able to accommodate another base rod, whereby the receiving elements 14b, 13c and that not shown pressing receiving element pressing-holding-pressing on one further base rod, not shown, would act. The wire piece 19 thus shows a particularly simple embodiment several receiving elements on different base bars to act simultaneously. In the receiving elements 14b, 13c and a receiving element, not shown would the two outer pressing receiving elements 14b and the receiving element, not shown, on not shown plant element, namely its base rod press while the middle holding receiving element 13c supports the base rod. Not with the chosen one aligned arrangement of the receiving elements (13a, 14a, 13b) or (14b, 13c and the receiving element, not shown), alternately pressing or holding onto the base rod, i.e. act with different pressure points, is therefore the position of the maximum stress in the stress position and the resulting state of tension in Non-use or use position for the contact element determinable.

Figure 2 shows a section of the crockery basket 1 after Figure 1, the plate rake 8b in almost vertical Use position is shown. The plate rake 8b is between Non-use and use position in an area between 0 ° and 90 ° swiveling, the stop G 11 the plate rake 8b only in the vertical position of use and an automatic snapping or folding the plate rake 8b to the left prevented. The base bar 9b points in relation to its stress position shown in FIG. 3 9c a reduced voltage.

Figure 3 shows a crockery basket 1 according to Figure 1, the Disc rake 8 shown in a stress position 8c is. The angle between the non-use and stress position is approximately 45 °. At a fixed Swivel range of 90 ° in the first quadrant of the coordinate system is the angle in the stress position approx. 45 ° to the horizontal and can with the angle, which the spikes 10 occupy with the horizontal coincide. Compared to Figures 1 and 2, the Position of the stop G 11 changed. This is located However, it does not have a stop function in the stress situation. It cannot be represented that the base rod 9c and therefore the entire plate rake 8c as mentioned above in the stress position has a maximum of its tension.

FIG. 4 shows a crockery basket 1 according to FIG. 1, the Plate rake 8d in a non-ingestible rest position as an example is shown. The tension - free rest position of the Plate rake 8d is 180 ° with respect to FIG. 3 rotated further at 225 ° and thus the stress situation shown there across from. Would be the G 11 stop on the base rod end piece not available, so would at least the axis 5 of the wheels 4 or cross struts, not shown 7 of the crockery basket bottom 2 of the plate rakes 9d on the ingest hindered its rest position below the crockery basket bottom 2.

As already mentioned above, is not in Figures 1 to 4 can be shown that the base rod 9,9a-d between non-use, Stress, use and rest position various Goes through stages of tension.

Figure 5 shows a second preferred embodiment at least one pivotable in the crockery basket 1 of a dishwasher arranged plate rake 8 being simultaneously Non-use, use, stress and rest position shown on four different plate rakes 8a-d are. It is shown as an example that the plate rake 8a-d do not extend over the entire width of the crockery basket 1 must, but rather across the width of the crockery basket 1 several plate rakes 8a-d, in the exemplary embodiment shown two plate rakes 8a and 8d or 8c and 8b can be arranged. On one end piece of all base bars 9a-d the stop G 11 is bent over, this only for the plate rake 8c and 8a in stress and non-use position is visible. Opposite at the stop G 11 The end piece of the base rods 9a-d is a crank each 18 cranked and a pressing spring element 15a acts on the crank 18. The receiving elements 16a and 15b complete the storage as in the first embodiment of the base rod 9a-d and do not work through it aligned arrangement as well as alternating arrangement of pressing and holding spring or receiving elements and thus the pressure points on every single curved base rod 9a-d generating tension, the tension of the spring element 15a is larger than that in this pressure point acting tension on the base rod. In principle are like in the first embodiment, the angle and tension ratios in non-use, stress, use and Non-use position the same, so each of the base bars 9a-d has a maximum stress in the stress position and an automatic snapping of the base bar 9b and thus the plate rake 8b from a reduced voltage Use position is prevented by a stop G 11 to to enable a wash-free setting of wash ware.

As also described in the first embodiment, is in the second embodiment in Figure 5 by the spring or receiving elements 15a, 16a, 15b of the type holding-pressing realized, 15a and 15b realize a Fixed bearing in the X and Y directions, 16a is a semi-loose bearing realized. The interaction of the bearings can be: Pressure points on the base bar, stress relationships of the contact element and directions from the first Embodiment are transferred. The guy holding, holding, holding is also feasible, the crank 18th would have to be arranged in the middle. in principle is the position and size of the maximum voltage due to the angle of attack of the spring element 15a and the maximum vertical Difference of the receiving element 15a compared to the Recording elements 16a and 15b can be determined, the crank 18 or the spring element 15a according to the selected Ratios or vice versa.

Figure 6 shows a section of Figure 5, with others Details of the crockery basket 1 for better illustration are omitted. The plate rake 8a is in Non-use. Through the cross strut 7, its further movement to the rest position 8d, cf. Fig. 9 prevented. The crank 18 is to the receiving element acting on it 15a in a position in which the voltage maximum has not yet been reached. As a bearing for the base bar 9a are only the two outer pressing bearing elements 15a and 15b visible since a longitudinal strut 6 (in FIG. 5 visible), which represents a holding receiving element 16a, 6 has been omitted for the sake of clarity. The G 11 stop is not yet in operation.

FIG. 7 again makes it clear that three bearing elements 15a, 16a, 15b are at least necessary, which are of the push-hold-push type in order to snap the plate rake from a stress position 8c into a use position 8b or non-use position 8a enable.
FIG. 7 shows a detail from FIG. 5 with a plate rake 8b in the position of use. The stop G 11 prevents further movement of the plate rake 8b to the left and supports the plate rake 8b on the axis 5 of the wheel attachment or a rod of the side wall 3. As mentioned above, the spring or receiving elements 15a, 16a, 15b are designed as bearing elements. The plate rake 8b has already passed its maximum tension when swiveling out of its non-use position 8a (shown in FIG. 6) through its stress position 8c (shown in FIG. 8) into its use position 8b (shown in FIG. 7) and is determined without play in the position of use, the Disc rake 8b and in particular its base rod 9b are still in a stress-reduced state with regard to the stress situation. A further stop Z 17 can be seen in FIG. 7, which is arranged in the vicinity of the receiving element 15b on the base rod 8b, this being shorter than the spikes 10, but oriented like this. The stop Z 17 prevents movement of the base bar 8, 8a-d in the direction of the free coordinate axis Z, ie through the side walls 3 of the crockery basket 1.

Figure 8 shows a section of Figure 5 with the plate rake 9c in the stress position at approx. 45 °, the selection the stress situation mainly from the angular position of the receiving element 15a and the position of the upper Crank piece 18a depends in the receiving element 15a. In this The base rod 9c and thus the plate rake 8c have a position not representable the state of maximum tension and snapped automatically in its use or 8b position 8a in order to assume a reduced-voltage state. Assuming a dead state 8d is prevented by the stops G 11 and N.

A section according to FIG. 5 is shown in FIG the plate rake 9d exemplarily in a non-ingestible rest position is shown. The G 11 stop was in the Illustration omitted, as well as all others as stops N-acting cross struts 7. The tension-free rest position lies the load situation with maximum stress at approx. 225 ° opposite and is thus compared to this shown in Figure 8 Stress position rotated by 180 °. It is visible that the crank 18 is in contact with the receiving element in the rest position 15a loses. As a result, the base rod 8d only the two other mounting elements reduce the tension 16a and 15b. In the rest position it is Tension of the plate rake 8d compared to the other layers 8a-c least, the taking of a tension-free state is possible in principle if the base rod 8d has play in all three receiving elements 15a, 16a and 15b.

In Figure 10, the principle of operation of a first embodiment i.a. 1 to 4 shown. The non-aligned arrangement of three recording and / or Spring elements shown, in which a preferably arcuate prestressed base rod is clamped. The Arrows place the alternating pressure points on the bass bar represents.

In Figure 11 is the principle of operation of a second embodiment i.a. 5 to 9 shown. The base bar is not exactly in line arranged receiving and / or spring elements clamped. The arrows represent those that act alternately on the base rod Pressure points.
