Swivel arms, Flebel, the adapter, the locking pin and the like. These terms are not meant to be limiting, that is to say, by different working positions or the mirror-symmetrical design or the like, these references may change.

In Figs. 1 - 26, a first embodiment of a sliding pivot mechanism according to the invention is shown, an over-extraction of a pus in a Kor 2 of a furniture or Flaushaltsgerätes 1, here in the form of a dishwashing machine, attached lower tray 10 from a in Fig. 1st shown starting position can be verscho ben to a shown in Fig. 10 over-extension position.

In addition, the dishwasher may still contain an upper tray 1 1, which can be moved out of the inner space 23 by means of a pullout guide, not shown.

27-47 show a second embodiment of an inventive Shen sliding pivot mechanism with which the tray 10 can be moved from a shown in Fig. 27 at play raised raised pivot base position LP2 in an over-pull position shown in game in Fig. 45.

Common to both variants are the pivoting mechanism with which the tray 10 designed here as a lower dish rack can be pivoted between a lower pivot base position LP1 shown in FIGS. 4 and 37 and an upper pivot base position LP2 shown in FIGS. 20 and 27, respectively Pull-out guide 5.

The swivel mechanism has at least two swivel arms 3, 4, which can be fixed pivotably on the body 2 and are arranged parallel to one another, which form a parallel guide for the pull-out guide 5. The pullout guide 5 has a guide rail 51, a guide rail 51 relative to the Füh displaceable center rail 52 and a relative to the center rail 52 sliding guide rail 53, to which the lower tray 10 is fastened be.

The two pivot arms 3, 4 are held with an upper end on a Be tenwandhalterung 12 via respective pivot joints 31, 41 pivotally. The side wall bracket 12 itself is mounted on a side wall 21 of the body 2 of the furniture or Flaushaltsgerätes 1.

To damp the pivoting movement of the pivot arms 3, 4, a damper 13 is mounted between the pivot arm 3 and the side wall mount 12 to allow pivoting in both directions with the least possible expenditure of force.

On the pivot arm 4, a locking lever 7 is arranged in a joint 71, which carries a locking pin 72 in its free end.

The free ends of the pivot arms 3, 4 are connected via joints 32, 42 with a support 6. The carrier 6 is attached to the guide rail 51 of the statement guide 5. The joints 31 and 41 are mutually in the same direction Rich and at the same distance as the joints 32 and 42, so that a Paral lelführung for the T carrier 6 against the side wall bracket 12 is formed.

The lower tray 10 is connected to the track rail 53 of the pullout guide 5 via holding elements 15, as shown in Figs. 2 and 28.

As shown by way of example in FIGS. 7 and 30, the carrier 6 has a Arre animal plate 61 with a locking lug 62 and a locking groove 63. The locking plate 61 has a circular curved portion on which the locking pin 72 runs during the pivotal movement of the tray along.

The front lateral locking tab 62 blocks a pivoting movement of the lower tray 10 from the lowered position to a raised position.

The introduced in the upper part of the locking plate 61 locking groove 63 locks a pivotal movement of the lower tray 10 from the upper loading and unloading position shown in Fig. 20 in the lowered position. In the following, a first embodiment variant of a locking mechanism will be described with reference to FIGS.

The locking mechanism has a switching device 8 which is adjustable between two switching positions S1 and S2 and with the running rail 53 in egg ner predetermined partially extended Schwenkbasisposition LP1, LP2 relative to the guide rail 51 in one of the switch positions S1, S2 together with the other components of the pullout guide 5 is movable in a continued Schiebebe movement relative to the guide rail 51.

The switching device 8 in this case has an actuating element 81 and coupled to the actuating element 81, between the switching positions

51 and S2 adjustable release lever 83 on.

The unlocking lever 83 can be seen clearly in FIG. 6, for example. As shown here, the unlocking lever 83 is coupled at a first end via a connecting lever 84 via hinges to the shift lever 82.

Both the shift lever 82 and the release lever 83 are coupled via jewei time pivots 93, 94 with an adapter 9, which has a housing 91.

At a second end of the unlocking lever 83, a sliding stop 831 is formed frontally with which the locking pin 72 of the locking lever 7, as a comparison of Figures 6 and 7 with Figures 5 and 16 shows, from the one handle with the locking lug 62 of the carrier 6 can be pushed out to free the pivotal movement of the pivot arms 3, 4.

Figs. 1-3 show the sliding pivot mechanism and the bottom of this fortified bottom shelf 10 in its inserted into the body 2 of the dishwasher here as dishwashers Flaulhaltsgerätes 1 inserted starting position.

4 - 7 show the sliding pivot mechanism in a position in which the lower tray 10 is pushed out in the extension direction A from the interior 23 of the body 2 in a first Schwenkbasisposition LP1. In this case, the lower tray 10 was together with the track rail 53 and the center rail

52 moved relative to the guide rail 51 in the extension direction A. As can be clearly seen in FIG. 6, in this position the sliding stop 831 of the unlocking lever 83 is positioned in the extension direction A immediately behind the locking pin 72.

Starting from this first swivel base position LP1, the user can now decide whether he would like to advance the lower tray 10 further into the overfeed position shown in FIGS. 10-12 or whether he will pivot the lower tray 10 up into the raised loading and unloading position would like to.

In order to bring the lower tray 10 in the Überauszugpositi shown in Figs. 10 - 12, he must operate the switching device 8.

In the embodiment shown here he must move the here designed as a vertically be wegbarer handle lever actuator 81 from the first shift position S1 shown in FIGS. 4 and 5 move upward in a raised position shown in Fig. 8 S2.

By raising the actuating element 81, a lowering of the rear end of the shift lever 82 and associated lifting of the slide stop 831 formed free end of the release lever 83 in the position shown in Fig. 9, in which the slide stop 831 is now positioned above the locking pin 72 and so further extending the lower tray 10 in the extension direction A in the over-extraction position shown in Figs. 10 - 12 allows.

To raise the lower tray 10 at a later time into the raised loading and unloading position, it is necessary to first bring the lower tray 10 back into the first Schwenkbasisposition LP1.

A renewed actuation of the switching device 8 is not necessary because when pushing back the release lever 83 along its underside on the locking pin 72 can slide and thereby automatically by retracting Ar retierstifts 72 is raised and falls back after passing over the locking pin 72 in the switching position S1.

By slightly advancing the lower tray 10 in the extension direction A, the position shown in Figs. 13 - 16 is then reached, in which the Ar retierstift 72 using the unlocking lever 83 from its locked position below the locking lug 62 of the carrier 6 is pushed out, as can be clearly seen in Fig. 16.

Then, by pulling up the lower tray 10, the lower from position 10, as shown in Figs. 17 - 19 are pivoted upward. In this case, the locking pin 72 is guided animal plate 61 along the circular portion of the Arre between locking tab 62 and locking groove 63 until the hoisted loading and unloading position is reached.

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

As a result, the lower tray 10 in the raised loading and unloading position or here also referred to as the second pivot base position LP2, locked.

In order to pivot the lower tray 10 from this raised second Schwenkbasisposi tion LP2 back into the lowered position, a re-actuation of the switching device 8 is necessary.

For this purpose, the actuating element 81 is moved again from the switching position S1 in the switching position S2, as shown in Fig. 24. In this case, the Ent locking lever 83 is raised again in the position shown in Fig. 25.

In this position, the locking pin 72 lifted by the integrally formed on the release lever 83 Flebeanschlag 832 from the locking groove 63 up ge and thus gives the pivotal movement of the pivot arms 3, 4 in the un lower lowered position free.

The second embodiment variant of the locking mechanism will be described in more detail below with reference to FIGS. 27-47.

FIGS. 27-30 show, as a starting position, the second swivel base position LP2 of the lower tray 10 in its raised loading and unloading position, in which the locking pin 72, as can be clearly seen in FIG. 30, rests in the locking groove 63 of the locking plate 61.

From this second Schwenkbasisposition LP2 out the user now have two options: First, the lower tray 10 further from the body 2 of the here designed as a dishwasher Flaushaltsgerätes 1 in zugsrichtung A to move in an overfeed position or secondly the unte re tray 10 to pivot from the raised loading and unloading in the lowered position.

To carry out the pivoting movement in the lower lowered position, an actuation of the switching device 8 is also necessary here so that the actuating element 81 is moved from its first switching position S1 in the angeho bene switching position S2.

As a result, also takes place here on the lowering of a ment of the Betätigungsele 81 spaced end of the shift lever 82 lifting a lifting stop 832 ^'of the release lever 83 ^' . The lifting stop 832 ^' below engages the locking pin 72 and lifts it from its locking position in the locking groove 63 of the locking plate 61st

As can be clearly seen in Figs. 29 and 32, in this embodiment, the connecting lever 84 is not coupled to the rear ends of the shift lever 82 and the release lever 83 ^' , but in the horizontal direction be seeks between the adapter 9 ^' with the shift lever 82 connecting Ge steering 95 ^' and the adapter 9 ^' with the release lever 83 ^' connect the joint 96 ^' , so that a lowering of the rear end of the shift lever 82 causes an increase in the rear end of the release lever 83 ^' and thus the lifting stop 832 ^' .

After release of the locking pin 72 from the locking groove 63, the lower Ab 10 can now be pivoted from the raised loading and unloading in the lowered position as shown in Figs. 34 - 36 and 37 - 39 is shown.

From this lowered into the first Schwenkbasisposition LP1 position of the lower tray 10, the lower tray 10 can then be inserted into the interior 23 of the body 2 of Geschirrspülmaschi ne 1 against the extension direction A in the position shown in FIGS. 40 and 41.

On the other hand, if the user wishes to prefer the lower tray 10 from the second upper pivot base position LP2 to the over-extension position shown in FIGS. 45-47 in the extension direction A, an actuation of the switching device 8 is necessary in such a way that the actuating element 81 can be moved out of the position shown in FIG. 34 and 35 is moved downward to the first shift position S1 shown in Figs. As a result, as can be clearly seen in FIG. 43, the rear end of the shift lever 82 is raised. To enable this, the rear end of the switching lever 82 is connected to a second housing part 92 ^' of a two-part housing having adapter 9 ^' .

Here, a first housing part 91 ^'is coupled to the shift lever 82 via the hinge 95 ^' and the release lever 83 ^' via the hinge 96 ^' , while the second housing part 92 ^' is coupled only to the shift lever 82. The two te housing part 92 ^' is to form a passage channel 98 ^' for the locking pin 72 between the first housing part 91 ^' and the second housin seteil 92 ^' perpendicular to the guide rail 53 slidably held on the lower tray 10.

For secure vertical guidance of the second housing part 92 ', a slot 97' may be present, the menwirkt together with a fixed bolt.

As shown in Fig. 43, thereby a movement of the lower tray 10 re relatively to the locking pin 72 in the extension direction A allows, without the Arre animal pin 72 is lifted out of its locked position in the locking groove 63 of the locking plate 61.

The lower tray 10 can be pulled out in the extraction position A shown in Figs. 45 - 47 position in the extension direction. In this excess traction movement, the lower tray 10 is moved together with the guide rail 53 relative to the center rail 52 in the extension direction A.

To the lower tray 10 then push back back into the second pivot base position LP2 against the extension direction A, he is neutally an operation of the switching device 8 is necessary, in which again the loading actuating element 81 is moved from the switching position S1 in the switching position S3 to again to form the channel 98 between the first housing part 91 ^' and the second housing part 92 ^{' of} the adapter 9 ^' . After being pushed back into the second Schwenkbasisposition LP2, the switching device 8 can be losgelas sen, so that the actuator 81, the lever 82 and the release lever 83 ^' returns to the switching position S1, in which the He-claim 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, with the lift stop 832 ^'provided end of the release lever ^83' is moved downward and can be moved during the pushing back of the over-extension position to the second pivotal base position LP2 under the locking pin 72nd

It is conceivable that the achievement of the first and / or second Schwenkbasispo position LP1, LP2 each acoustically perceptible by the user. It is also conceivable to make the pivot base positions LP1, LP2 perceptible to the user by means of an optical display element.

In the case of an optional one-piece design of the adapter 9 ^' , it is unimaginable to form the channel 98 ^' on the adapter housing. Conceivable in all variants is also to couple the actuator 81 or the lever 82, for example, with a preferably attached to the tray spring element or a detent cam to hold the Schaltein device 8 in a neutral position, for example, S1 or due to scarf tion.
