EP3261489B1 - Sliding-pivoting mechanism of a shelf of a piece of furniture or of a domestic appliance, piece of furniture, and domestic appliance - Google Patents

Description

The present invention relates to a sliding pivot mechanism of a shelf of a piece of furniture or household appliance for extracting and lifting the tray from a body of the furniture or household appliance according to the preamble of claim 1. The invention further relates to a piece of furniture and a household appliance with such a sliding pivoting mechanism ,

A generic sliding pivot mechanism is for example from the WO 2014/033092 A1 or the WO 94/04059 A1 known. The sliding pivot mechanism described here has proven itself in practice.

It is desirable to be able to determine the achievement of an unloading position of the tray even more safely after the sliding-swivel operation and to be able to achieve such an unloading position of the tray with the least possible expenditure of force.

These objects are achieved by a sliding pivot mechanism of a piece of furniture or household appliance with the features of claim 1 and by a piece of furniture with the features of claim 11 and a domestic appliance with the features of claim 12.

The sliding swivel mechanism according to the invention has at least two swivel arms rotatably fixed to at least one of the side walls of the body and having a first end rotatably fixed parallel to the plane of the side walls and parallel to each other. At respective second ends of these pivot arms, a guide rail is so pivotally fixed parallel to the plane of the side walls, that the guide rail from a lower position within the body in a raised, upper position is at least partially pivotable outside of the body. In the guide rails on both sides of the tray runs a linearly displaceable running rail to which the tray is attached. The sliding pivot mechanism further has a releasably arranged on the guide rail and one of the pivot arms and by a fixed to the running rail or the tray release unit Locking mechanism, which serves to lock the tray in at least one intermediate position between the lower position and the upper position.

The locking mechanism has a pivotably and resiliently held on one of the pivot arms web, with a projecting in the direction of the guide rail bolt, which is guided along a guide member fixed to the guide rail with at least three locking points.

By locking the tray in predetermined positions from which the tray can be solved by means of the release unit, it is clearly visible to the user whether and when the lock is released, since he must actively solve this by pressing the release unit.

The intermediate position of the shelf between the lower position and the upper position in which the shelf can be locked has the advantage that the user already has full access to the entire shelf without much effort in this intermediate position. In this case, in the case of a dishwasher equipped with such a slide-pivoting mechanism, the front edge of a tray designed as a basket does not protrude beyond the front edge of the door of the dishwasher, so that residual water present on the cleaned dishes can not drip onto the floor via the door of the dishwasher as would be the case, for example, in the case of storage of the dish rack via a classic full extension.

Advantageous embodiments of the invention are the subject of the dependent claims.

The preferably formed as grooves locking points of the guide element ensure a secure hold of the respective position of the pivot arms. Due to the spring preload by the resiliently held web of the bolt is pressed upon reaching the locking points in each case in the groove. In the first locking point, the tray is preferably in the lower position, in the second locking point, the tray is preferably in the intermediate position and when retracting the bolt in the third locking point, the tray is preferably in the upper position.

The intended for unlocking such a locking position release unit can be actuated via an associated with this actuator.

The actuating element is designed according to a preferred embodiment as a handle part, in particular as a handle lever, rotary handle or as an actuating button.

The connection between the actuating element and the release unit is preferably carried out via a mechanical transmission means, such as a Bowden cable.

Also conceivable are other transmission means such as a push rod, a transmission, a belt drive or the like.

In particular, when using such a sliding pivot mechanism in a household appliance such as a dishwasher, it is advantageous to use a mechanical transmission means which is moved by the power of the user and thus does not represent an additional consumer of electrical energy. A shielding of electronics in the case of an electrical transmission medium from moisture is not necessary when using a mechanical transmission means.

The release unit of the sliding pivot mechanism has, according to a preferred embodiment, a housing with a slide displaceable in a guide by actuating the actuating element, with which the bolt is movable out of the locking point, in particular can be pressed.

According to a further preferred embodiment variant, a stop is arranged on one of the pivot arms such that over the entire pivoting range a horizontal movement of the tray into the body of the furniture or domestic appliance is at least partially suppressed or completely prevented by striking the housing against the stop.

This ensures that after the unlocking of the tray insertion of the shelf into the body is prevented.

According to a further preferred embodiment, reaching a locking position of the tray is acoustically perceptible and thus gives the user feedback that the tray is kept secured in a predetermined position.

In the following description of the figures, terms such as top, bottom, left, right, front, back etc. refer exclusively to those in the respective Figures selected exemplary representation and position of the sliding pivot mechanism, the tray, the pivot arms, the release unit, the guide member and the like. These terms are not intended to be limiting, that is to say, by different working positions or the mirror-symmetrical design or the like, these references may change.

In FIG. 1a is denoted by the reference numeral 2 a body of a piece of furniture or household appliance. On side walls 21, 22 of the body 2 each have a sliding pivot mechanism for extending and lifting a tray 11 is attached. Each of these sliding pivot mechanisms has at least two pivot arms 3, 4. The pivot arms 3, 4 are on the side walls 21, 22 of the body 2 or, as in the embodiment shown here, on a side wall bracket 10, which in turn is fixed to one of the side walls 21, 22, with a first end 31, 41 parallel to the plane the side walls 21, 22 rotatably fixed and spaced parallel to each other.

At respective second ends 32, 42 of the pivot arms 3, 4 is a guide rail 5 parallel to the plane of the side walls 21, 22 fixed pivotally. This allows the guide rail 5 from a lower position within the body 2, as in FIG. 1 is shown in a raised upper position, shown in Figs FIGS. 5a and 8a , swing outside of the body 2.

Details on the structure of the sliding pivot mechanism and their operation are in the aforementioned WO 2014/033092 A1 described in more detail, the content of which is hereby incorporated into this application for explaining many details of the sliding pivot mechanism.

The displacement of the tray 11 from the completely housed within the body 2 position is made possible by a linearly displaceable in the guide rail 5 running rail 6, to which this tray 11 is attached.

As in the Figures 1b and 1c shown, the sliding pivot mechanism on a guide rail 5 and on one of the pivot arms 3, 4 arranged locking mechanism for locking the tray 11 in a plurality of positions. It is in FIG. 1b a first variant of a guide element 7 'and in Figure 1c a second variant of a guide element 7 is shown.

This locking mechanism preferably has a web 12 which is pivotably and resiliently held on one of the swivel arms 3, 4 and has a bolt 121 projecting in the direction of the guide rail 5, which has a guide element 7, 7 'fastened along the guide rail 5 with at least three locking points 71, 72, 73 is feasible. By the spring bias by the resiliently held web 12 of the bolt 121 is pressed upon reaching the locking points 71, 72, 73 respectively in the groove. At the first locking point 71, the tray 11 is preferably in the lower position, in the second locking point 72, the tray 11 is preferably in the intermediate position and when retracting the pin 121 in the third locking point 73, the tray 11 is preferably in the upper Position.

So the bolt 121 is in the in FIG. 1a shown position of the tray 11 received within the body 2 in the first locking point 71. As a result, a pivoting movement of the sliding pivot mechanism is blocked. The bolt 121 is guided in a slot 44 at a second end 42 of the second pivot arm 4 and resiliently biased in the locking point 71.

At a front edge of the tray 11 at least one actuating element 8 is fixed, which, as in Figure 7a shown, via a preferred mechanical transmission means 82, in particular a Bowden cable, with a release of the locking mechanism serving release unit 9 is connected. The release unit 9 is fixed in the preferred embodiment shown here in the rear region of the tray 11. It is also conceivable the fixation of the release unit 9 on the running rail 6. Preferably located on each side of the tray 11, a release unit 9, which is driven by a common actuator to realize a synchronous unlocking of the locking mechanism of the tray 11.

A preferred embodiment of such a release unit 9 is in the FIGS. 7a to 7e shown in detail. The release unit 9 has a housing foot 91 for fixing the release unit 9 on the tray 11 or the running rail 6, a housing 93 with a slide 94 in a guide 94 by operating the actuating member 8 slidable.

The slider 95 has in the embodiment shown here on its rear side a web 951 with a longitudinal slot 952 in which a closed by a plug 83 tail of the here designed as a Bowden cable mechanical transmission means 82 is inserted. The Bowden cable is received above the web 951 in a guide slot 921 on the deflecting 92.

By operating the actuating element 8, the Bowden cable 82 pulls the slider 95 in the guide 94 upwards in the direction of the deflecting element 92 and presses it, as for example in FIG. 4b is shown, the bolt 121 out of the locking point 72 of the guide element 7 out. As a result, the sliding swivel mechanism is unlocked from the current position. After unlocking the tray 11 can be further pivoted upwards in an upper position or further down to a lower position. For the first variant of the guide element 7 '(shown in FIG FIG. 1b ) is mandatory for unlocking the operation of the actuating element 8 is required.

The further embodiment of the release unit 9 will be described below with reference to an exemplary extraction and lifting operation of the tray 11 from the body 2 of the furniture based on FIGS. 2 to 6 described.

The FIGS. 2a to 2c show the tray after the horizontal shift out of the interior 23 of the body 2 out. As in the FIGS. 2b and 2c can be seen, in this horizontal displacement of the tray 11, the release unit 9 is moved together with the tray 11 from the interior of the body 2 to the front.

A in the extension direction x front web 96 of the guide 94 of the release unit 9 pushes the pin 121 out of a first locking point 71 of the guide member 7 and thus allows a pivotal movement of the pivot arms 3, 4 upwards. This unlocking requires no actuation of the actuating element. 8

FIG. 3a shows the tray 11 in an intermediate position between the in FIG. 1a shown lower position and the in FIG. 5a shown upper position. The pivot arms 3, 4 are pivoted by a predetermined angle from the initial vertical position into an inclined position.

As in the FIGS. 3b and 3c can be seen, in this pivotal movement of the bolt 121 has been moved from the first latching point 71 via a cam in a second latching point 72. This second locking point 72 is preferred shaped so that an independent pivoting back without unlocking is prevented in the lower position by the formed between the two locking points 71, 72 cams.

A direct movement of the tray further into the upper position, shown in FIG. 5a on the other hand, is not hindered by the shape of the guide member 7, so that the tray 11, if necessary, directly from the lower position, shown in FIG FIG. 2a in the upper position, shown in FIG. 5a , can be raised.

In the alternative embodiment of the guide element 7 'according to FIG. 1b a further movement of the tray is further prevented in the upper position by a molded between the two locking points 72, 73 cams, so that the tray 11 can be raised only by active unlocking using the actuating element 8 further in the upper position.

As in the FIGS. 3b and 3d is shown, the slider 95 is in its initial position at non-actuation of the actuating element 8 in a position in the guide 94 arranged such that the pin 121 remains in its locking position in the second locking point 72 by the bias of the resiliently held web 12. The bolt 121 thereby moves through an inlet channel 97 during the horizontal movement of the tray 11 to the Entriegelungssteg 96 out.

During the subsequent pivotal movement of the pivot arms 3, 4, the pin 121 is guided along the Entriegelungsstegs 96 in the guide 94 of the release unit 9 above the slider 95 out. When the actuating element 8 is not actuated, the pin 121 is pressed into the second locking point 72 by the resiliently held web 12.

Will the actuator 8, as in FIG. 4a shown actuated, then the slider 95, as in the Figures 4b and 4d shown pulled in the guide 94 upwards and pushes the pin 121 against the bias of the resiliently held web 12 from the second locking point 72 out. Alternatively, the tray 11 can be pressed with the use of the guide member 7 by force also upwards, since the guide member 7 above the second locking point 72 has a slope.

FIG. 5a shows the tray 11 in the upper end position. As in the FIGS. 5b and 5c can be seen, the bolt 121 is due to the bias of the resiliently held web 12 in this position in the third locking point 73 of the guide element 7 a. The third locking point 73 is shaped so that in the insertion direction of the tray 11, the guide member 7 is formed as a stop 74.

The insertion of the tray 11 preferably during the entire pivoting process is prevented by a stop 43 which is arranged on one of the pivot arms 3, 4, in the embodiment variant shown here on the second pivot arm 4 and the preferred during the entire pivotal movement of the pivot arms 3, 4th rests against the housing 93.

To pivot the tray 11 from this upper position back to the lower position, the bolt 121 must be pushed out of this third locking point 73.

This will in turn, as in FIG. 6a shown actuates the actuator 8, resulting in a shift of the slider 95 of the release unit 9 in the guide 94 upwards. In this case, the pin 121 is pushed out of the here formed as a groove third locking point 73, as shown in the FIGS. 6b to 6d is shown.

The actuating element 8 can be designed differently. So the actuator 8 in the FIGS. 1 to 7 shown embodiments as a handle part, in particular as a handle lever formed with an actuating handle 81. The handle lever can be attached to the tray 11 itself pivotable or attached to a shelf 11 rod 111th

So is at the in FIG. 9a embodiment shown, the actuating element 8 as a hand lever 81, similar to a handbrake lever of a bicycle formed.

At the in FIG. 9b In the embodiment shown, the actuating element 8 "is arranged at two points 84 on a rod 111, wherein the user actuates the release unit 9 by pressing the actuating handle 81 'against the rod 111.

In the FIG. 9c For example, the actuator 8 "is actuated relative to the rod 111 by rotating the actuation handle 8".

In a further alternative embodiment variant, shown in FIG FIG. 9d , the actuating element 8 '''as a push button 81''' with a housing 85 '''is formed, which is arranged on the rod 111.

In all variants of the actuating element 8, 8 ', 8' ', 8' '' they can be connected by mechanical transmission means 82 with the release unit 9.

In the FIGS. 8a to 8e is again the sliding-tilting operation of the sliding-swing mechanism of a piece of furniture or household appliance 1, shown here in the embodiment of a flushing device. Good to see in FIG. 8a in that both in the upper position of the tray 11 designed here as a rinsing basket, a front edge of the tray 11 does not protrude beyond a front edge of a rinsing appliance door 24, so that even if there is still residual water left on crockery placed in the rinsing basket or during loading of the basket of liquids or food residues on a floor on which the household appliance 1 is placed is prevented.

In contrast, in the case of a tray 11 'with a full extension, consisting of an additional middle rail 6a', shown in FIG FIG. 8b , the front edge of the tray 11 'protrudes beyond the front edge of the toilet door 24. However, the use of a full extension would be necessary to alternatively realize a full access to the lower tray 11 'in a lowered position.

In the in FIG. 8c shown intermediate position in which the tray 11 can be locked, it can be seen again that the tray 11 does not project beyond the front edge of the Spülgerätetür 24. In this intermediate position, full access to the contents of the tray 11 is still possible.

The Figures 8d and 8e show the tray 11 in the lower position before insertion into the body 2 of the household appliance. 1

In addition, in the body, an upper tray 13 may still be arranged, which is movable relative to the body 2 by linear movement.
