Description

The present invention relates to a piece of furniture or a household appliance with a body and at least one shelf guided in the body and a sliding and pivoting mechanism for pulling out and lifting the shelf out of the body of the furniture or household appliance according to the preamble of claim 1.

A generic sliding-pivoting mechanism is, for example, from WO 2014/033092 A1 known. Such sliding and pivoting mechanisms can be used, for example, in furniture or household appliances such as dishwashers, refrigerators, freezers or cooking appliances, in order to pull out a shelf, for example in the form of a drawer, a crockery basket, container or food carrier, from the interior of the furniture or household appliance and lift it upwards to be able to A user can easily load or unload the shelf in the raised position.

Such sliding and pivoting mechanisms have proven themselves in practice. In particular, the locking of the sliding and swiveling mechanism, which prevents a simultaneous sliding movement of the rail and swiveling movement of the swivel arms, ensures reliable operation of the sliding and swiveling mechanism and a secure raised position in which the user can easily load or unload the shelf.

It would be desirable to further develop the sliding and swiveling mechanism so that the lower shelf attached to the sliding and swiveling mechanism can be extended in the lower, lowered position or in the upper, raised position, for example to provide better access to the floor area of the furniture or To achieve household appliance located facilities, such as a salt compartment of a dishwasher or a hidden storage compartment such as a secret drawer of a piece of furniture.

An optional over-extension in the upper position is particularly helpful if an upper shelf of the furniture or household appliance also needs to be moved forward a bit for a short time in order to enable access to objects stored on this upper shelf without the lower one First having to move the shelf down from its raised position.

Such a slide-pivot mechanism that can perform an over-extension of the lower shelf in the upper raised position is, for example, from DE 10 2015 102 390 A1 known.

The object of the present invention is to provide a simple switching mechanism for such a sliding and pivoting mechanism.

The task is solved by a piece of furniture or household appliance with the features of claim 1.

According to the invention, the piece of furniture or household appliance has a sliding/pivoting mechanism of a shelf for pulling out and lifting the shelf from a body of the furniture or household appliance, at least two pivoting arms that can be pivoted on the body and are arranged parallel to one another, which form a parallel guide of a drawer guide. The pull-out slide has a guide rail, a center rail that can be displaced relative to the guide rail, and a running rail that can be displaced relative to the center rail, to which the shelf is fastened.

The sliding and pivoting mechanism also has a locking mechanism arranged on the guide rail and on one of the pivoting arms to prevent a simultaneous pivoting and sliding movement. The locking mechanism has a switching device that can be adjusted between at least two switching positions and with which the slide rail can be moved in a predetermined, partially extended pivot base position relative to the guide rail in one of the switch positions together with the other components of the pull-out slide in a continuous sliding movement relative to the guide rail.

The switching device has an actuating element and an unlocking lever which is coupled to the actuating element and can be adjusted between the switching positions.

With the help of such a switching device, it is possible to swivel the shelf, starting from a swivel base position, either up into a raised position or down into a lowered position or to move the shelf in a continuous sliding movement relative to the guide rail and thus enable over-extension .

This ensures better access to parts of the furniture or household appliance that are located in a bottom area of the body of the furniture or household appliance, for example the salt compartment of a dishwasher.

If a lower shelf pivoted into the raised position is overextended, the overextension makes it possible to better access objects on an upper shelf arranged in the furniture body without having to move the lower shelf pivoted upwards back into its lower position beforehand.

The actuating element enables the user to bring the switching device into the desired switching position in a simple manner.

Advantageous design variants are the subject matter of the dependent claims.

According to an advantageous embodiment variant, the switching device can be adjusted between three switching positions. This allows the user to actively intervene to control the two options for moving the shelf, namely, on the one hand, to release the pivoting movement of the pivot arms to lower the shelf, or, alternatively, to further extend the shelf into an over-extended position.

According to an advantageous embodiment variant, the locking mechanism is designed in such a way that it blocks pivoting of the pivoting arms when the shelf is lowered and not extended into the pivot base position or when the shelf is raised into an upper loading and unloading position.

According to a further advantageous embodiment variant, the locking mechanism has a locking pin that is movably arranged on one of the swivel arms, and a locking plate that is mounted in a stationary manner with respect to the pull-out guide and with which the locking pin interacts.

The locking mechanism according to a further preferred embodiment variant for releasing a sliding movement of the tray from a raised pivoting base position is designed such that the actuating element is positioned in a second switching position which is raised compared to an initial position (first switching position).

According to a further embodiment variant, the locking mechanism for releasing a continued sliding movement of the tray in a lowered swivel base position is designed in such a way that the actuating element is positioned in the second switching position.

According to yet another embodiment variant, the locking mechanism for releasing a continued sliding movement of the tray in a raised pivoting base position is designed such that the actuating element is positioned in a lowered third switching position compared to the starting position (first switching position).

This variant of the locking mechanism is used in particular to enable over-extension of the shelf raised into the upper loading and unloading position.

According to a further preferred embodiment variant, the locking pin can be moved out of a position blocking the pivoting movement of the pivoting arms by the unlocking lever set in the first switching position.

This means that the user does not have to actuate the switching device to lift the shelf from the lowered to the upper loading and unloading position, since the unlocking lever is positioned in its first switching position in such a way that it releases the locking pin when the shelf is moved horizontally out of the body of the Furniture or household appliance pushes out of the locked position.

According to a further embodiment variant, the unlocking lever is positioned in the lowered pivot base position of the tray in the second switch position disengaged from the locking pin.

This means that the user has to actuate the switching device and thus the release lever in order to pull out the shelf into the over-extension moved away from the collision trajectory hitting the locking pin when it was pulled out.

According to a further embodiment variant, the actuating element is designed as a vertically movable grip lever which is coupled via a switching lever and a connecting lever to the unlocking lever which is movably fixed on the shelf or the running rail.

The vertically movable grip lever is positioned, for example, on the front side of the shelf and is therefore easily accessible and operable for the user.

In this case, the unlocking lever is particularly preferably pivotably attached to an adapter arranged on the shelf or the running rail.

In a first preferred embodiment variant, the unlocking lever has a lifting stop.

In a second alternative embodiment, the unlocking lever has a lifting stop and a sliding stop.

The latter variant is used in particular for over-extension when the shelf is in the lowered position.

The first variant is used in particular for the over-extension in the raised loading and unloading position of the shelf.

In a first preferred embodiment variant, the adapter has a housing which is coupled to the shift lever and the unlocking lever via rotary joints.

In particular for over-extension of the tray in the raised loading and unloading position, the adapter is designed with a two-part housing, with a first housing part being coupled to the switching lever and the unlocking lever and a second housing part being coupled only to the switching lever, the second housing part being used to form a Passage channel for the locking pin between the first housing part and the second housing part is held perpendicular to the running rail on the tray.

This enables the second housing part to be raised relative to the first housing part when the switching device is actuated, in which the actuating element is brought into the third switching position, thus releasing the locking pin so that the tray can be moved further horizontally from the swivel base position into the over-extension can.

In the following description of the figures, terms such as top, bottom, left, right, front, rear, etc. refer exclusively to the exemplary representation and position of the swivel arms, the lever, the adapter, the locking pin and the like selected in the respective figures. These terms are not to be understood as limiting, i.e. these references can change due to different working positions or the mirror-symmetrical design or the like.

In the Figures 1 - 26 a first embodiment of a sliding and swiveling mechanism according to the invention is shown, which allows an over-extension of a lower shelf 10 fastened in a body 2 of a piece of furniture or household appliance 1, here in the form of a dishwasher, from an in 1 shown starting position to an in 10 shown over-extension position can be moved.

In addition, the dishwasher can also contain an upper shelf 11 that can be moved out of the interior 23 by means of a pull-out guide (not shown).

the 27-47 show a second embodiment variant of a sliding and pivoting mechanism according to the invention, with which the tray 10 consists of an in 27 exemplary shown raised pivot base position LP2 in an exemplary in Figure 45 shown over-extension position can be moved.

Both variants have in common the swivel mechanism with which the rack 10, which is designed here as a lower dish rack, can be placed between a 4 and 37, respectively, and a lower swing base position LP1 shown in FIGS 20 or 27 shown upper swivel base position LP2 are pivotable and a pull-out guide 5.

The pivoting mechanism has at least two pivoting arms 3 , 4 which can be pivotally secured to the body 2 and are arranged parallel to one another, which form a parallel guide for the pull-out guide 5 .

The pull-out guide 5 has a guide rail 51, a center rail 52 that can be displaced relative to the guide rail 51, and a running rail 53 that can be displaced relative to the center rail 52, to which the lower shelf 10 is attached.

The two swivel arms 3, 4 are pivotally held with an upper end on a side wall bracket 12 via respective pivots 31, 41. The side wall mount 12 itself is mounted on a side wall 21 of the body 2 of the piece of furniture or household appliance 1 .

To dampen the pivoting movement of the pivoting arms 3, 4, a damper 13 is mounted between the pivoting arm 3 and the side wall bracket 12 in order to enable pivoting in both directions with as little effort as possible.

A locking lever 7 is arranged in a joint 71 on the swivel arm 4 and carries a locking pin 72 in its free end.

The free ends of the swivel arms 3, 4 are connected to a carrier 6 via joints 32, 42. The carrier 6 is attached to the guide rail 51 of the pull-out guide 5 . The joints 31 and 41 are in the same direction and at the same distance from one another as the joints 32 and 42, so that a parallel guide for the carrier 6 relative to the side wall bracket 12 is formed.

The lower shelf 10 is connected to the running rail 53 of the pull-out guide 5 via holding elements 15, as shown in FIGS 2 and 28 is shown.

As exemplified in the 7 and 30 shown, the carrier 6 has a locking plate 61 with a locking lug 62 and a locking groove 63 . The detent plate 61 has a circular curved portion along which the detent pin 72 rides during pivotal movement of the tray.

The front side locking tab 62 thereby blocks pivotal movement of the lower tray 10 from the lowered position to a raised position.

The locking groove 63 introduced in the upper area of the locking plate 61 blocks a pivoting movement of the lower shelf 10 from the in 20 upper loading and unloading position shown in the lowered position.

The following is based on the Figures 1 - 26 describes a first embodiment of a locking mechanism.

The locking mechanism has a switching device 8 which can be adjusted between two switching positions S1 and S2 and with which the running rail 53 can be moved in a predetermined partially extended swivel base position LP1, LP2 relative to the guide rail 51 in one of the switching positions S1, S2 together with the other components of the extension guide 5 can be moved relative to the guide rail 51 in a continued sliding movement.

The switching device 8 has an actuating element 81 and an unlocking lever 83 which is coupled to the actuating element 81 and can be adjusted between the switching positions S1 and S2.

For example, the release lever 83 is in 6 clearly visible. As shown here, the release lever 83 is coupled at a first end to the shift lever 82 via a connecting lever 84 via pivot joints.

Both the shift lever 82 and the unlocking lever 83 are coupled to an adapter 9 which has a housing 91 via respective pivot joints 93 , 94 .

At a second end of the release lever 83, a sliding stop 831 is formed on the front side, with which the locking pin 72 of the locking lever 7, as a comparison of figures 6 and 7 with the figures 5 and 16 shows, can be pushed out of engagement with the locking lug 62 of the carrier 6 to give the pivoting movement of the pivot arms 3, 4 freely.

the Figures 1 - 3 show the sliding and pivoting mechanism and the lower shelf 10 fastened to it in its initial position, pushed into the body 2 of the household appliance 1, which is designed here as a dishwasher.

the Figures 4 - 7 show the sliding and pivoting mechanism in a position in which the lower shelf 10 is pushed out in the pull-out direction A from the interior 23 of the body 2 into a first pivoting base position LP1. In this case, the lower shelf 10 together with the running rail 53 and the middle rail 52 was moved relative to the guide rail 51 in the pull-out direction A.

As in 6 is clearly visible, in this position the sliding stop 831 of the unlocking lever 83 is positioned directly behind the locking pin 72 in the extension direction A.

Based on this first pivot base position LP1, the user can now decide whether he continues the lower shelf 10 in the Figures 10-12 would like to advance the over-extension position shown or whether he would like to pivot the lower shelf 10 into the raised loading and unloading position.

To lower shelf 10 in the Figures 10 - 12 To bring the over-extension position shown, he must actuate the switching device 8.

In the embodiment variant shown here, he must use the actuating element 81, which is designed here as a vertically movable grip lever, from the one shown in FIGS 4 and 5 shown first switching position S1 up to an in 8 move shown raised switching position S2.

By raising the actuating element 81, the rear end of the switching lever 82 is lowered and, as a result, the free end of the unlocking lever 83, which is designed as a sliding stop 831, is raised into the in 9 shown position, in which the sliding stop 831 is now positioned above the locking pin 72 and so a further extension of the lower tray 10 in the extension direction A in the in the Figures 10 - 12 shown over-extension position allows.

In order to swing up the lower tray 10 to the loading and unloading raised position at a later time, it is necessary to first return the lower tray 10 to the first swing base position LP1.

It is not necessary to actuate the switching device 8 again, since when the release lever 83 is pushed back, it can slide along its underside over the locking pin 72 and is automatically raised by driving over the locking pin 72 and, after driving over the locking pin 72, falls back into the switching position S1.

By slightly pushing the lower tray 10 in the pull-out direction A is then in the 13 - 16 Reaches the position shown, in which the locking pin 72 using the release lever 83 from its locked position under the locking lug 62 of the carrier 6 is pushed out, as in 16 is easy to see.

Then, by pulling up the lower tray 10, the lower tray 10 as shown in FIGS 17 - 19 shown to be pivoted upwards. The locking pin 72 is guided along the circular section of the locking plate 61 between the locking nose 62 and the locking groove 63 until the raised loading and unloading position is reached.

In this raised loading and unloading position, the locking pin 72 is pressed down into the locking groove 63 of the locking plate 61 by gravity.

As a result, the lower shelf 10 is locked in the raised loading and unloading position, or also referred to herein as the second pivoting base position LP2.

In order to be able to pivot the lower shelf 10 from this raised second pivot base position LP2 back into the lowered position, the switching device 8 must be actuated again.

For this purpose, the actuating element 81 is again moved from the switch position S1 to the switch position S2, as shown in 24 is shown. In doing so, the release lever 83 is pushed back into the in 25 position shown raised.

In this position, the locking pin 72 is lifted upwards out of the locking groove 63 by the lifting stop 832 formed on the unlocking lever 83 and thus releases the pivoting movement of the pivoting arms 3, 4 into the lower, lowered position.

The second embodiment of the locking mechanism is based on the 27 - 47 described in more detail.

the 27 - 30 show, as a home position, the second pivot base position LP2 of the lower tray 10 in its loading and unloading raised position where the detent pin 72 is engaged as shown in FIG 30 is clearly visible, in the locking groove 63 of the locking plate 61 rests.

From this second swivel base position LP2, the user now has two options: First, the lower shelf 10 further from the body 2 of the household appliance 1, which is designed here as a dishwasher, in the direction of extension A to move to an over-extension position or, secondly, to pivot the lower shelf 10 from the raised loading and unloading position to the lowered position.

In order to carry out the pivoting movement into the lower, lowered position, it is also necessary here to actuate the switching device 8 in such a way that the actuating element 81 is moved from its first switching position S1 into the raised switching position S2.

As a result, a lifting stop 832′ of the unlocking lever 83′ is also raised here via the lowering of an end of the switching lever 82 spaced apart from the actuating element 81 . The lifting stop 832' reaches under the locking pin 72 and lifts it out of its locking position in the locking groove 63 of the locking plate 61.

As in the 29 and 32 is clearly recognizable, in this embodiment variant the connecting lever 84 is not coupled to the rear ends of the switching lever 82 and the unlocking lever 83', but viewed in the horizontal direction between the adapter 9' connecting the switching lever 82 and the joint 95' and the adapter 9'. with the release lever 83' connecting pivot 96', so that a lowering of the rear end of the switching lever 82 raises the rear end of the release lever 83' and thus the lifting stop 832'.

After releasing the locking pin 72 from the locking groove 63, the lower tray 10 can now be pivoted from the raised loading and unloading position to the lowered position as shown in FIGS 34 - 36 and 37 - 39 is shown.

From this lowered into the first pivot base position LP1 position of the lower shelf 10, the lower shelf 10 can then in the figure 40 and 41 shown position in the interior 23 of the body 2 of the dishwasher 1 against the pull-out direction A are inserted.

On the other hand, if the user wants to move the lower shelf 10 from the second upper swing base position LP2 to the position shown in FIGS 45 - 47 Prefer over-extension position shown in the extension direction A, actuation of the switching device 8 is necessary in such a way that the actuating element 81 from the in the 34 and 35 shown first switching position S1 in the in Figure 42 switching position shown S3 is moved down.

This will, as in Figure 43 is clearly visible, the rear end of the shift lever 82 is raised. In order to make this possible, the rear end of the shift lever 82 is connected to a second housing part 92' of an adapter 9' having a two-part housing.

A first housing part 91' is coupled to the shift lever 82 via the joint 95' and to the unlocking lever 83' via the joint 96', while the second housing part 92' is only coupled to the shift lever 82. The second housing part 92' is held on the lower shelf 10 so that it can be displaced perpendicularly to the running rail 53 in order to form a passage channel 98' for the locking pin 72 between the first housing part 91' and the second housing part 92'.

For the secure vertical guidance of the second housing part 92', an elongated hole 97' can be present, which interacts with a fixed bolt.

As in Figure 43 is shown, this allows the lower shelf 10 to move relative to the locking pin 72 in the extension direction A without the locking pin 72 being lifted out of its locking position in the locking groove 63 of the locking plate 61 .

The lower shelf 10 can be in the 45 - 47 shown over-extension position in the extension direction A are further extended. During this over-extension movement, the lower shelf 10 is moved in the extension direction A together with the running rail 53 relative to the middle rail 52 .

In order to subsequently slide the lower shelf 10 back into the second swivel base position LP2 counter to the pull-out direction A, the switching device 8 must be actuated again, in which case the actuating element 81 is moved from the switching position S1 to the switching position S3 again in order to again open the channel 98 between the first housing part 91' and the second housing part 92' of the adapter 9'. After it has been pushed back into the second swivel base position LP2, the switching device 8 can be released so that the actuating element 81, the switching lever 82 and the unlocking lever 83' return to the switching position S1, in which the lifting stop 832' is pushed under the locking pin 72.

During the movement of the switching device 8 from the switching position S1 to the switching position S3, the end of the release lever 83' provided with the lifting stop 832' is moved downwards and can thus be moved under the locking pin 72 when pushed back from the over-extension position into the second pivoting base position LP2.

It is conceivable that the user can hear the first and/or second swivel base position LP1, LP2 being reached. It is also conceivable to make the swivel base positions LP1, LP2 perceptible to the user by means of an optical display element.

In the case of an optional one-piece configuration of the adapter 9', it is conceivable to form the channel 98' on the adapter housing.

It is also conceivable for all variants to couple the actuating element 81 or the shift lever 82, for example, to a spring element or a locking cam preferably attached to the shelf, in order to hold the shifting device 8 in a neutral position, eg S1, or to return it after shifting has taken place.
