Description

Sliding pivot mechanism of shelf of furniture or household appliance and furniture or household appliance with sliding pivot mechanism

Technical Field

The present invention relates to a sliding pivot mechanism for a shelf of furniture or a household appliance for pulling out and lifting the shelf from a body of the furniture or the household appliance. The sliding pivot mechanism has at least two pivot arms which are pivotably fastened to the body and are arranged parallel to one another, the pivot arms forming a parallel guide for the pull-out guide. The pull-out guide has at least one guide rail and a slide rail that is movable relative to the guide rail. Furthermore, the invention relates to a piece of furniture or a household appliance having such a sliding pivot mechanism.

Background

For example, a sliding pivot mechanism of this type can be used in a piece of furniture or a household appliance, such as a dishwasher, a cooling device, a refrigerator or a cooking appliance, for pulling out and lifting up a shelf, which may be a drawer, a cutlery basket, a container or a cooking receptacle, from the interior of the piece of furniture or the household appliance. In the raised position, it is achieved that the shelf is easily loaded or emptied for the user.

A sliding pivot mechanism of the type described is known, for example, from publication EP 2890271B 1. In this embodiment, a latching pin is arranged in the region of the joint on the free end of the pivot arm, which latching pin is mounted radially displaceably in a spring-loaded manner and is latched in a groove of a guide element, which is mounted in a positionally fixed manner in the region of the joint relative to the guide rail, in order to prevent a displacement movement of the running rail and a simultaneous pivoting movement of the pivot arm.

When the shelf is extended in the lower pivot position, the catch pin first snaps into one of the slots, thereby preventing pivotal movement during extension of the shelf. The detent is moved out of the detent position when the shelf is fully extended by a corresponding stop on the shelf, and then a pivoting movement is possible. During the pivoting movement, the catch pin is retracted into a guide formed on the shelf and thus prevents the shelf from being pushed in again during the pivoting movement.

In the fully pivoted-up position of the shelf, the catch pin is latched in a second of the slots in the catch plate, whereby the shelf is reliably held in this upper position until the further active pulling out or pushing in of the shelf moves the catch pin out of the second latching position by means of a further stop, whereby the pivoting movement is released and the shelf can be lowered. When the shelf is completely lowered, the catch pin leaves the guide path, so that the shelf can be pushed in again. Thereby, process control for the pull-out and pivoting movement is formed by the catch pin, the catch plate and the guide.

In this publication, a so-called partial pull-out is used as a pull-out guide, in which the slide rail is guided directly in the guide track. Thus, in the lower pivot position, the shelf cannot fully protrude from the body. When the pivot arm pivots upward, the pivot arm is transferred from a position pointing substantially vertically downward into a horizontal position, as a result of which the entire pull-out guide continues to move out of the body. In this way, in the pivoted position, the shelf is moved out of the body to such an extent that it is positioned, for example, in front of another shelf arranged in the upper region of the body.

In order to be able to completely project the shelf out of the body also in the lower pivoting position of the pivoting arm, instead of a partial pull-out, a so-called full pull-out can be used as a pull-out guide. In addition to the guide rail and the running rail, the full extension comprises at least one intermediate rail, wherein the intermediate rail is mounted so as to be movable relative to the guide rail and relative to the running rail.

However, a problem with this type of design of the sliding pivot guide is that, when the pivot arm is pivoted upward, the shelf which has already been completely protruding from the body in the lower pivot position moves out of the body to such an extent that an unsuitable weight distribution for the device or the piece of furniture is obtained by the shelf which protrudes excessively from the body.

When the sliding pivot mechanism is used in a dishwasher, the open door of the dishwasher additionally serves as a dirt and drip collector for food residues and liquids, which can also drip from the dishes or from the projecting rack, if necessary. In a typical geometry of a dishwasher, the length of the swing-out door corresponds approximately to the depth of the rack, i.e. the depth of the cutlery basket projecting therefrom. If the cutlery basket projects excessively out of the body by a pivoting movement when the full pull-out is used, the front end of the cutlery basket is located in front of the edge of the open door, so that the door no longer serves as a dirt and drip catcher for the entire rack.

Disclosure of Invention

The object of the invention is to improve a sliding pivot mechanism of the type mentioned at the outset in such a way that a shelf which is fully or substantially fully extended in the lower pivot position does not protrude too far from the body when the shelf is pivoted upwards.

This object is achieved by a sliding pivot mechanism or a piece of furniture or a household appliance having such a sliding pivot mechanism having the features of the respective independent claims. The subject matter of the dependent claims is advantageous embodiments and refinements.

A sliding pivot mechanism according to the invention of the type mentioned at the outset is distinguished by a coupling device which couples the sliding rail or the shelf with one of the pivot arms in such a way that the sliding rail is retracted relative to the guide rail during at least part of the upward and/or downward pivoting of the pull-out guide.

By coupling the shelf or the sliding rail with one of the pivot arms, the moving movement can be linked with the pivoting movement when the pivot arm is pivoted, i.e. during the pivoting movement, so that the shelf or the sliding rail is retracted when pivoting upwards and, correspondingly, is extended again when pivoting downwards.

This coupling on the one hand assumes the function of a latching so that the shelf cannot be retracted by the operator and collide with, for example, another shelf when pivoting upwards or in the pivoted position. On the other hand, the shelf is prevented from following a circular trajectory and protruding too far out of the body when it is pivoted upwards by pulling back the shelf or the slide.

In an advantageous embodiment of the slide and pivot mechanism, the coupling device has a guide element which is fixed on the shelf or the slide rail and has a guide curve. Furthermore, the coupling means preferably have a guide pin which engages into the guide curve when the shelf is pivoted upwards. For example, the guide curve may be configured as a slot in the guide element.

It is also preferred that the guide curve is open towards at least one side to accommodate or release the guide pin. The guide element and the guide pin are positioned relative to each other in such a way that the opening of the guide curve is positioned above the guide pin when the shelf is fully lowered and extended. Thereby, first the shelf can be fully extended without the guide pin hitting the guide element. Subsequently, if a pivoting process is carried out, the guide pin can enter directly into the guide curve and the guide element can follow the guide pin as the pivoting arm continues to pivot.

In a further advantageous embodiment of the sliding pivot mechanism, the guide pin is arranged on one of the pivot arms and is preferably positioned spaced apart from a connecting line which extends through the (pivoting) joint of the associated pivot arm. This can be achieved structurally by arranging the guide pin on a cantilever arm which is oriented in or parallel to the pivot plane of the associated pivot arm and projects out of the pivot arm.

The guide pin thus arranged and positioned on the pivot arm projects forward beyond the lower joint of the pivot arm when the pivot mechanism is lowered, and moves back in its horizontal position relative to the joint (and thus the guide track of the pull-out guide) when the pivot mechanism is pivoted upward. At the same time, the guide pin moves upward, in particular at the beginning of the upward pivoting movement, as a result of which the guide pin engages directly into the (downwardly open) guide curve.

Furthermore, the course of the guide curve determines the kinematic mechanism (Bewegungskinematik) of the coupling of the shelf and the pivot arm. For example, the guide curve has at least one vertical section in order to transmit the horizontal movement of the guide pin 1:1 to the retraction of the shelf. If the guide curve extends partially transversely, an additional forward or rearward movement of the supplementary shelf relative to the guide pin is furthermore possible.

In a further advantageous embodiment of the sliding pivot mechanism, a catch is provided which prevents pivoting of the pivot arm when the shelf is lowered and not fully extended and/or when the shelf is fully raised. By means of the coupling device, the movement is already prevented when the shelf is raised. The latching device also ensures that the displacement movement is released only when the shelf is fully extended. In this way, a complete process control is achieved by the latching device in combination with the coupling device. Furthermore, the latching device can be configured to prevent downward pivoting of the shelf when the shelf is fully raised. Thus, unintentional downward pivoting during loading or emptying of the shelf is prevented. Preferably, an actuating lever is provided to be able to release the catch and lower the shelf again in this upper position.

Preferably, the latching device has a latching pin which is movably arranged on one of the pivot arms and a latching plate which is mounted in a positionally fixed manner relative to the pull-out guide and interacts with the latching pin. The guide element can have a stop which releases the interaction of the detent pin and the detent plate when the shelf is fully extended and lowered. The guide element present according to the invention can therefore also be used to unlock the pivoting latch, whereby stops which are arranged separately on the shelf or the sliding rail for this purpose can be dispensed with.

In a development of this arrangement, it is proposed that the guide pin also forms the detent pin. In other words, the pin, i.e., a single element, functions not only as a guide pin, but also as a latch pin. Thus saving material and further simplifying the structure of the slide and pivot mechanism with the same function. The guide and detent pin thus formed in combination follows two guide bends: a guide bend in the guide element, and for example a latching groove, which serves as a guide bend in the latching plate.

It is particularly advantageous to use a sliding pivot mechanism with a pull-out guide which has at least one intermediate rail and is configured as a full pull-out.

The piece of furniture or household appliance according to the invention has a body and at least one shelf which is guided by a sliding pivot mechanism of this type and can be extended and lifted out of the body. Which can achieve the advantages associated with a sliding pivot mechanism.

Particularly advantageously, the sliding pivot mechanism can be used in a dishwasher as a domestic appliance, wherein the rack is a (lower) cutlery basket.

Detailed Description

In fig. 1 and 2, an example of the use of the sliding pivot mechanism according to the invention is first shown in isometric views, respectively.

A body 2 of a dishwasher 1 is shown, in which an inner cavity 4 is laterally delimited by a side wall 3. For visibility reasons, the dishwasher 1 is shown without a door, which is usually a pivoting door, which is articulated in a pivotable manner about a horizontal axis in a lower region of the dishwasher.

The interior 4 of dishwasher 1 has, during operation, two cutlery baskets, in particular a bottom cutlery basket 50 and a top cutlery basket 60, which are designed as rotating baskets in the usual manner. In fig. 1, the two

cutlery baskets

50, 60 are retracted into the interior 4 of the body 2.

The upper cutlery basket 60 is supported in the interior 4 in a known manner by a pull-out guide which is only horizontally displaceable. The cutlery basket 50 is supported in the body 2 by a sliding pivot mechanism according to the invention, which allows the cutlery basket 50 to be extended and subsequently pivoted upwards. The slide pivot mechanism includes a pivot mechanism 10 and a pull-out guide 20.

The extended and upwardly pivoted state of the lower cutlery basket 50 is shown in fig. 2. In this case, the lower plate basket 50 is raised to the same height as the upper plate basket 60. In this position, a simple and return-proof loading and emptying of the cutlery basket 50 is also achieved.

In fig. 3 to 5 and 6a, 6b, 7a, 7b and 8a to d, a first embodiment of the slide and pivot mechanism according to the invention is shown in more detail, wherein different positions of the slide and pivot mechanism during the lifting process are shown by way of example. Second and third embodiments of a slide and pivot mechanism according to the present invention are shown in fig. 9a-12d and 13a-14 b.

In the description, concepts such as above, below, left side, right side relate only to illustrations of selected examples in the respective drawings. The conceptual front and rear generally relate to the pull-out direction of the pull-out guide of the slide pivot mechanism. The front side is the side facing the user and facing forward during the pull-out process.

It should be noted that the sliding pivoting mechanism shown can be used as in furniture, for example in the dishwasher 1 shown in fig. 1 and 2 or more generally in household appliances of this type. Here, the cutlery basket 50 shown in fig. 1 and 2 is an example of a shelf, which accordingly in other applications may be a cooking support and/or a (bookshelf) base.

In fig. 3 to 5 and 6a to 8a, the sliding pivot mechanism of the first embodiment is shown in different operating positions in a complete side view, respectively. Typically, for the simultaneous lifting and lowering and extension of the lower cutlery basket 50, two sliding pivot mechanisms of mirror-symmetrical construction are provided on each side of the lower cutlery basket 50. In fig. 3 to 5 and 6a, 6b, 7a, 7b and 8a to d, respectively, only the sliding pivot mechanism with a part of the cutlery basket 50 is shown.

Fig. 6b to 8b, which are respectively associated, show a detail of fig. 6a to 8a in an enlarged view. In the fully pivoted-up and extended position shown in fig. 8a and b, a further side view is additionally shown in fig. 8c and an isometric side view is shown in fig. 8 d.

For visibility reasons not all elements in all figures are provided with reference signs. However, like reference numerals refer to like elements throughout the drawings.

In fig. 3, 4 and 5, the pull-out sequence of the sliding pivot mechanism is first shown, in which the cutlery basket 50 occupies different positions: a fully retracted position in fig. 3, a fully extended position in fig. 5, and a position therebetween in fig. 4.

The pivoting mechanism 10 comprises a base plate (mounting plate) 11 with which the shown sliding pivoting mechanism can be fixed in an inner cavity of the body, for example on the inner side of the side wall 3 of the body according to fig. 1 and 2.

On the base body 11, the two

pivot arms

12, 13 are pivotably connected in a joint 121 or 131. The respective free ends of the

pivot arms

12, 13 are connected to the support 15 in the

joints

122 and 132. The engaging

portions

121 and 131 and the engaging

portions

122, 132 are in the same direction and in the same distance from each other, thereby forming a parallel guide for the holder 15 with respect to the base plate 11. For the sake of distinction, the two

pivot arms

12, 13 are referred to in succession as first pivot arm 12, likewise carrying arm, and second pivot arm 13, likewise control arm.

On the control arm 13, the latch lever 14 is disposed in the engaging portion 141, and the latch lever 14 carries a latch pin 142 on its free end portion. The function of drive lever 14 or latch pin 142 is explained in detail again below.

Here, the pullout guide 20 is a complete pullout portion having a guide rail 21, an intermediate rail 22, and a slide rail 23. The guide rail 21 is connected to the support 15, whereas the slide rail 23 carries a shelf, here a cutlery basket 50. When the cutlery basket 50 is pulled out, the sliding rail 23 is moved essentially relative to the intermediate rail 22, wherein the sliding rail can additionally be moved relative to the guide rail 21, so that the cutlery basket 50 protrudes completely out of the body of the dishwasher.

During the pulling out of the cutlery basket 50 from the fully retracted position (fig. 3) into the fully extended position (fig. 5), the pivoting mechanism 10 is locked. This is achieved by the catch pins 142 co-acting with the catch plate 151, which is best seen in fig. 7 b.

Fig. 7b shows the region of the support 15 starting from the inside, i.e. in the direction of the cutlery basket 50. In this figure, it can be seen that the latching plate 151 is a correspondingly designed region of the carrier 15, wherein the rotary joint 132 is arranged in the region of the latching plate 151. The detent plate 151 has a circular curved section along which the detent pin 142 travels when pivoting.

Laterally, latching lugs 152 are formed on the latching plate 151 and latching slots 153 are formed in the upper region. In the pivoted state shown in fig. 3 to 5, in which the pivot mechanism 10 is fully lowered, the detent pin 142 is positioned below the detent lug 152 and is held in this position under spring loading. For this purpose, a spring, which is not visible here, is formed between the control rod 13 and the locking rod 14. The latching groove 153 for the upper pivoted state fulfils the same function as the latching lug 152 in the lower pivoted state.

On the cutlery basket 50, on the rear end thereof, a guide element 30 is fitted, the guide element 30 providing in the lower region a stop 32 running almost vertically. The guide element 30 can be made of plastic, for example, and clipped onto the cutlery basket 50. In an alternative embodiment, the guide element 30 can also be fixed directly on the slide rail 23.

When the cutlery basket 50 is completely pulled out in the lower pivoted position, a partial section of the stop 32 of the guide element 30 runs toward the detent pin 42 and thereby pushes the detent pin 142 below the detent lug 152, whereby the blocking of the pivoting movement is cancelled. In this case, the partial section of the stop 32 can be embodied as sharp-edged, rounded or planar.

After the latch has been released, further pulling out of the cutlery basket 50 causes the

pivot arms

12, 13 to pivot and thus the cutlery basket 50 to be lifted.

The starting state of the pivoting is shown in fig. 6a and in fig. 6b in an enlarged view. In addition to the unlocking function of the pivoting latch, the guide element 30 assumes a further function during the subsequent pivoting: first of all, a substantially vertically upwardly extending guide curve 31 is then provided, which opens downwards and forwards. At this time, the guide curve is configured as a slot in the guide element 30. In the fully pulled-out position of the cutlery basket 50, the opening of the guide curve 31 is positioned directly behind the guide pin 124, which is fixed on the cantilever arm 123, the cantilever arm 123 projecting forward from the first pivot arm 12 (lower pivot position relative to the first pivot arm 12). When the cutlery basket 50 is raised, the guide pin 124 penetrates into the guide bend 131. The starting state of the penetration is shown in fig. 6a and 6 b.

Fig. 7a and 7b show, for example, a further lifting of the cutlery basket 50 in the approximately 45 ° pivoted state of the

pivot arms

12, 13. The guide curve 31 forms a coupling means together with the guide pin 124. By the guide pin 124 penetrating into the guide bend 131, the displacement movement of the pull-out guide, in particular the position of the sliding rail 23 and thus of the cutlery basket 50, is linked to the pivoting movement. Depending on the positioning of the guide pin 124 relative to the engagement portion 122, the guide pin 124 is pulled back in its horizontal position relative to the engagement portion 122 as the pivot mechanism 10 pivots upward. Accordingly, the cutlery basket 50 is also pulled back relative to the joint 122.

Furthermore, the movement of the cutlery basket 50 can be influenced by the shape of the guide curve 31. Overall, it is possible in this way to achieve that the cutlery basket 50 does not project or projects only insignificantly when the pivoting mechanism 10 is pivoted upward, compared to its maximum pulled-out position in the lower pivoting position. It is thus prevented that the loaded cutlery basket 50 exerts an excessively strong tilting moment on the dishwasher, which can lead to tilting of the device, in particular in a free dishwasher not fixed under the work plate. Furthermore, food residues and liquids are prevented from dripping onto the kitchen floor into the area in front of the open door of the dishwasher.

In fig. 7a, a pull-out damper 70, which is not visible or shown to date, can also be recognized, which damps the pivoting movement. The pull-out damper can be designed with an internal force accumulator, so that a certain weight compensation of the dishwasher basket 50 is possible and pivoting in both directions is possible without resistance.

Subsequently, in fig. 8a to 8d, the pivoting mechanism 10 is shown in its upper pivoted state. Fig. 8a and 8b are again an overall view or detail from one side, here from the inside of the sliding pivot mechanism, that is to say from the side of the cutlery basket. Fig. 8c shows the same detail as fig. 8b, viewed only from the outside. Fig. 8d shows an isometric side view of the obliquely outer side looking from above to the outside of the slide and pivot mechanism.

In fig. 8a to 8d, it can be seen on the one hand that the detent pin 142 latches into the detent groove 153 and thus the pivot mechanism 10 latches in the upper position shown. As a result of the retraction of the cutlery basket 50 relative to the bearing 15, which is effected by the guide pin 124 and the guide curve 31, the latching pin 142 moves into the region of action of the unlocking element 40.

The unlocking means 40 comprises an actuating rod 41 which is guided in a clamping manner on the opposite side of the cutlery basket 50 and here likewise forms the actuating rod of the identically constructed unlocking means of the above-described sliding pivot mechanism. The actuation lever 41 is actuated by the intermediate lever 42 to the unlocking lever 43, and the unlocking lever 43 is pivotably supported in the engagement portion 431. The unlocking lever 43 surrounds the locking pin 142 with its free end in the form of a hook. When the clamping plate is actuated, the latching pin 142 is lifted by the lower stop 432 of the unlocking lever 43 and is thereby pushed out of the latching groove 153, so that the pivoting mechanism 10 can be pivoted and the cutlery basket 50 can be lowered again. The actuating lever 41 is guided through a bracket 44 which also couples the cutlery basket 50 in its front region with the sliding rail 23.

If the cutlery basket 50 should be lowered and pushed into the body again, the graphical sequence is carried out in the reverse order accordingly.

As the cutlery basket 50 is pivoted downward, it is first extended relative to the support 15 by the interaction of the guide pin 124 in the guide bend 31 until it reaches the lower, fully extended position.

In this position, the guide pin 124 is also released from the guide pin 31, so that the retraction of the cutlery basket is effected. Furthermore, the detent pin 142 latches behind the detent lug 152 of the detent plate 151, preventing further pivoting movement.

It should be mentioned that in the upper position of the cutlery basket 50, the locked pivoting movement can also be unlocked by the cutlery basket 50 itself, by the catch latch 142 being lifted out of the catch recess 153, in an alternative manner. For this purpose, for example, a slight movement play of the guide pin 124 in the guide curve 31 may be allowed. When the cutlery basket 50 is moved, the appropriately positioned stop 432 lifts the detent pin 142 out of the detent groove 153 in this gap, thereby releasing the pivoting movement.

A second embodiment of the slide and pivot mechanism according to the present invention is described below with reference to fig. 9a to 12 d. In the drawings, the same reference numerals denote elements that have the same or the same functions as in the first embodiment. For reasons of visibility, not all elements in all figures are provided with reference signs again.

Fig. 9a, 10a, 11a, 12a each show the slide and pivot mechanism in a side view in different displacement or pivot positions: fig. 9a shows a fully lowered and retracted position, fig. 10a shows a lowered and extended position, fig. 11a shows a partially upper pivoted position, and fig. 12a shows a fully upper pivoted position. In the respectively associated fig. 9b, 10b, 11b and 12b, the individual components of the sliding pivot mechanism are shown individually in a side view in the respective position.

In the basic structure, the slide pivot mechanism of the second embodiment corresponds to the first embodiment. If no differences are indicated below, reference is hereby made explicitly in terms of construction to the embodiment of the first example.

In the second exemplary embodiment, it is also provided that the lower cutlery basket 50 is pulled back when the pivoting mechanism 10 is pivoted upward. The retraction is again achieved in that the guide pin engages into the guide curve 31 of the guide element 30, the guide element 30 fitting on the slide rail 23 or alternatively on the cutlery basket 50.

In addition, in the second embodiment, as in the first embodiment, a latch for pivotal movement is provided when the lower cutlery basket 50 is retracted, and a lock for pivotal movement is provided after pivoting upward. Before the lower cutlery basket 50 can be pivoted downwards again, this locking must be released manually by actuating the actuating lever 41 of the unlocking portion 40. For this purpose, the catch pin 142 is located on the catch lever 14, which is hinged on the pivot arm 13, as in the first embodiment. The detent pin 142 rests in front of the detent lugs 152 or in the detent recesses 153 of the detent plate 151 formed on the support 15 and thus prevents a pivoting movement.

However, unlike the first embodiment, the click pin 142 is simultaneously a guide pin, and in the first embodiment, the guide pin is denoted by reference numeral 124. Thus, only a single pin is required, which has two functions (latching the pivoting movement and pulling back the cutlery basket 50).

As shown in fig. 9b, in the fully lowered and retracted position of the cutlery basket 50 (see fig. 9a), the catch 142 is located below the catch lug 152, whereby the pivoting movement is initially prevented. When the lower cutlery basket 50 is pulled out (see fig. 10a) into the fully extended position, the stop edge of the guide element 30 fastened to the cutlery basket 50 reaches the catch 142 and lifts the catch in front of the catch lug 152, thereby releasing the pivoting movement.

When the cutlery basket 50 is pivoted upward (see fig. 11a), the catch pin 142 is lifted by the movement of the pivot arm 13 (and thus the catch lever 14). The stop edge of the guide element 30 merges upward into the guide curve 31, as a result of which the detent pin 142 is retracted into the guide curve 31 and thus additionally has the function of the guide pin 124 according to the first exemplary embodiment.

Due to the curved shape of the guide curve 31, the movement of the catch latch 142 during the pivoting movement leads to a retraction of the lower cutlery basket 50. When the cutlery basket 50 is pivoted fully upwards (see fig. 12a), the latching pin 142 reaches the end of the guide curve 31 on the one hand and latches in the latching groove 153 on the other hand, whereby the cutlery basket 50 is fixed in the pivoted position. The guide curve 31 extends downward in its end region, so that a latching of the latching pin 142 into the latching groove 153 is achieved.

The sequence described above is reversed for the downward pivoting and pushing in of the lower cutlery basket 50. First of all, however, the detent pin 142 must be lifted out of the detent groove 153 manually by actuating the actuating lever 41.

This process is shown in fig. 12c and 12 d. Fig. 12c shows the support 15 and the guide element 30 as well as the actuating rod 41, similarly to fig. 12 b. In fig. 12d, the assembly of fig. 12c is shown without the support 15. The guide element 30 is shown transparent so that the components of the unlocking portion 40 located behind the guide element 30 are visible.

As shown in fig. 12d, the movement of the actuating lever 41 is transmitted via the intermediate lever 42 to the unlocking lever 43, which acts with a stop edge 432 below the latch 142. By pivoting the actuating lever 41 in the direction indicated by the arrow, the stop edge 432 is lifted and accordingly the latch lever 142 is lifted out of the latch groove 153, thereby releasing the pivoting movement.

In fig. 13a, b and 14a, b, a third embodiment of the slide and pivot mechanism according to the invention is shown in two different pulled-out positions. Fig. 13a and 13b show the slide and pivot mechanism in a lower and fully pushed-in state, whereas fig. 14a and 14b show the slide and pivot mechanism in a lower and fully pulled-out state.

In fig. 13a and 14a, the sliding pivot mechanism applied in the dishwasher 1 is shown in a corresponding isometric view. Here, the sliding pivot mechanism carries the cutlery basket 50. Furthermore, in the dishwasher 1, the upper cutlery basket 60 is in the retracted position. Fig. 13b and 14b each show the sliding pivot mechanism in a corresponding position in a side view with the cutlery basket 50 separated from the dishwasher 1.

In terms of basic structure, reference is made to the slide pivot mechanism according to the above-described embodiment. In the sliding pivot mechanism shown here, the

pivot arms

12, 13 of the pivot mechanism 10 are different in their angular position in the lower position of the sliding pivot mechanism. In the above illustrated embodiment, the

pivot arms

12, 13 are substantially vertical in the lower position of the cupboard 50. By means of this embodiment, a maximum lifting height between the lower position and the upper position, in which the pivot arm is oriented horizontally, is achieved.

In the embodiment shown in fig. 13a to 14b, the

pivot arms

12, 13 are inclined forward in the lower pivot position at an angle of about 20 degrees relative to the vertical. In this initial angular position, a slightly reduced upward lifting height of the lower cupboard 50 is achieved when the

pivot arms

12, 13 are the same length. For this reason, the offset brought forward by the abutment 15 (to which the pull-out guide 20 is fixed) is significantly smaller when pivoting upward. Accordingly, the coupling device, by means of which the slide rail is moved relative to the guide rail during upward pivoting, only needs to be moved over a smaller movement path. The guiding curve 31 of the coupling device causing the retraction can thus have a slope that is not very steep, thereby simplifying the movement process to be carried out smoothly and as far as possible without resistance.
