Description

The invention relates to a sliding pivot mechanism of a shelf of a piece of furniture or household appliance for removing and lifting the tray from a body of the furniture or household appliance. In this case, the sliding pivot mechanism has at least two swivel arms which can be fixed in a pivotable manner on the carcass and are arranged parallel to one another and which form a parallel guide for a pullout guide. The pullout guide has at least one guide rail and a guide rail displaceable relative to the guide rail. The invention further relates to a piece of furniture or household appliance with such a sliding pivot mechanism.

Such sliding pivot mechanisms may e.g. used in furniture or household appliances, such as dishwashers, refrigerators, freezers or cooking appliances to pull out a shelf, which may be a drawer, a crockery basket, a container or a food support, from the interior of the furniture or household appliance and lift up. In the raised position for a user comfortable loading or unloading of the tray is possible.

A sliding pivot mechanism of the type mentioned is for example from the document EP 2 890 271 B1 known. In this embodiment, a locking pin is arranged in the region of one of the joints at the free end of the pivot arms, which is mounted radially displaceable spring-loaded and engages in grooves of a guide member which is fixedly mounted to the guide rail in the region of the joint to a sliding movement of the running rail and a to prevent simultaneous pivoting movement of the pivot arms.

When moving out the tray in a lower pivot position of the locking pin is first engaged in one of the grooves, so that during the retraction of the tray, the pivoting movement is blocked. By a corresponding stop on the tray, the locking pin is moved out of the locked position when the tray is fully retracted, whereupon the pivoting movement can take place. During the pivoting movement of the locking pin moves into a formed on the tray guide, thereby blocking the re-insertion of the tray during the pivoting movement.

In a fully upwardly pivoted position of the tray, the locking pin locks in the second of said grooves in the lock plate, thereby securely holding the tray in the upper position until further active withdrawal or insertion of the tray by means of another stop disengages the lock pin the second locking position moves, whereby the pivoting movement is released and the tray can be lowered again. When the tray is completely lowered, the locking pin leaves the guide track so that the tray can be pushed back in again. By the locking pin, the locking plate and said guide thus a sequence control for the extension and the pivoting movement is formed.

In the cited document, a so-called partial extension is used as a pull-out guide, in which the running rail is guided directly in the guide rail. As a result, in the lower pivot position, the tray can not be completely moved out of the body. When pivoting the pivot arms, the pivot arms are transferred from a substantially vertically downwardly facing position in a horizontal position, whereby the entire pullout guide is further moved out of the body. In the upper pivot position, the tray is thereby moved so far out of the carcass that it is positioned, for example, in front of another tray arranged in the upper region of the carcass.

In order to be able to drive out the tray completely out of the body even in the lower pivot position of the pivot arms, a so-called full extension can be used as a pull-out guide instead of the partial extension. A full extension comprises in addition to the guide and running rail at least one center rail, wherein the middle rail relative to the guide rail and against the running rail is slidably mounted.

In such an embodiment of the sliding pivot guide, however, there is the problem that in the lower pivot position already completely driven out of the carcass tray is moved so far out of the carcass at a pivoting of the pivot arms, that is one for the device or the furniture unfavorable weight distribution results from the excessively driven out of the body tray.

When using the sliding swivel mechanism in a dishwasher, the open door of the dishwasher also serves as a dirt and drip catcher for leftovers and liquids that may still drip off the dishes or the shelf that has been moved out. In a conventional geometry of a dishwasher, the length of the swung-open door corresponds approximately to the depth of the shelf, ie the depth of the crockery basket moved out. If the crockery basket is driven excessively far out of the body by the pivoting movement when using a full extension, its front end is located in front of the edge of the opened door, so that it no longer acts as a dirt and drip catcher for the entire tray.

It is an object of the present invention to improve a sliding pivot mechanism of the type mentioned above so that a completely or substantially completely extended in the lower pivot position tray when pivoting the tray does not move excessively out of the carcass out.

This object is achieved by a sliding pivot mechanism or a furniture or household appliance with such a sliding pivot mechanism with the features of the respective independent claim. Advantageous embodiment and further development are the subject of the dependent claims.

A sliding pivot mechanism according to the invention of the type mentioned above is characterized by a coupling device which couples the running rail or the tray with one of the pivot arms, that the running rail is retracted during at least a portion of a high pivoting and / or swinging down the pullout guide relative to the guide rail.

By coupling tray or track with one of the pivot arms, the sliding movement during pivoting of the pivot arms, ie during the pivoting movement, be connected to this pivoting movement so that the shelf or running rail when pivoting back and is correspondingly extended when swinging down again.

This coupling takes on the one hand, the function of a lock, so that the shelf when pivoting or in a raised position by the operator can not be retracted and collides with, for example, another filing. On the other hand is prevented by the retraction of the shelf or running rail that the shelf when pivoting leaves a circular path and moves too far out of the body.

In an advantageous embodiment of the sliding pivot mechanism, the coupling device has a guide element with a guide curve which is fixed to the tray or the track rail. Furthermore, the coupling device preferably has a guide pin which engages in the guide curve when pivoting the tray. The guide curve may for example be formed as a slot in the guide element.

More preferably, the guide curve is open to at least one side to receive or release the guide pin. In this case, the guide element and the guide pin are mutually positioned so that an opening of the guide curve is positioned at fully lowered and extended shelf above the guide pin. As a result, the tray can first be fully extended without the guide pin abuts against the guide element. Then, when the pivoting operation is performed, the guide pin can retract directly into the guide curve and follow the guide element in a further pivoting of the pivot arms of the guide pin.

In a further advantageous embodiment of the sliding pivot mechanism of the guide pin is arranged on one of the pivot arms and preferably spaced from a connecting line positioned, which runs through (pivot) joints of the respective pivot arm. This can be constructively achieved, for example, by the guide pin is arranged on a boom which is aligned in or parallel to a pivot plane of the respective pivot arm and projects from the pivot arm.

Such arranged on the pivot arm and positioned guide pin protrudes with lowered pivoting mechanism forward beyond the lower hinge of the pivot arm and moves with respect to its horizontal position relative to the hinge (and thus the guide rail of the pullout guide) back when the pivoting mechanism is swung up. At the same time, especially at the beginning of the high pivoting movement, it performs a movement upwards, whereby it engages directly in the (downwardly open) guide curve.

The movement kinematics of the coupling of storage and swivel arm is also determined by the course of the guide curve. This may for example have at least one vertical section in order to transfer the horizontal movement of the guide pin 1: 1 to the retraction of the tray. If the guide curve crosswise sections, also an additional forward or backward movement of the tray is added to the guide pin.

In a further advantageous embodiment of the sliding pivot mechanism, a locking device is provided which blocks a pivoting of the pivot arms when the tray is lowered and not fully extended and / or when the tray is completely raised. By the coupling device, the sliding movement is already blocked when the tray is raised. By the locking device is additionally achieved that the sliding movement is released only when fully extended storage. By the locking device thus a complete sequence control is realized in connection with the coupling device. Next, the locking device to do so be configured to block a pivoting down of the tray when the tray is fully raised. This prevents unintentional swiveling down during loading or unloading of the tray. Preferably, an actuating lever is provided in order to solve the lock in this upper position again and to be able to lower the shelf.

Preferably, the locking device on a locking pin which is movably disposed on one of the pivot arms, and a locking plate which is fixedly mounted to the pullout guide and with which cooperates the locking pin. In this case, the guide element may have a stop that cancels the interaction of locking pin and locking plate at fully extended and lowered storage. The guide element according to the invention can thus also be used for unlocking the pivot lock, whereby a separately arranged for this purpose on the shelf or the running rail stop can be omitted.

In a further development of this arrangement, it is provided that the guide pin also forms the locking pin. In other words, a pin, so a single element, both used as a guide pin, as well as a locking pin. This saves material and further simplifies the structure of the sliding swivel mechanism with the same function. The co-formed guide pin thus follows two guide curves: the guide curve in the guide element and e.g. a locking groove, which represents a guide curve in the locking plate.

Particularly advantageously, the sliding pivot mechanism is used with a pullout guide, which has at least one middle rail and is designed as a full extension.

An inventive furniture or household appliance has a body and at least one tray which is guided by such a sliding pivot mechanism and can be moved out of the carcass and raised. This results in the advantages mentioned in connection with the sliding swivel mechanism.

Particularly advantageously, the sliding swivel mechanism can be used in a dishwasher as a household appliance, the tray is a (lower) crockery basket.

In the 1 and 2 First, an application example of an according to the application sliding tilt mechanism is presented in each case an isometric view.

Shown is a corpus 2 a dishwasher 1 in which an interior 4 sideways from side walls 3 is limited. For the sake of clarity, the dishwasher is 1 without a door represented, which is usually a hinged door, which is articulated in the lower region of the dishwasher pivotable about a horizontal axis.

The interior 4 the dishwasher 1 takes in operation two baskets, formed in the usual way as wire baskets on, specifically a lower dish rack 50 and an upper dish rack 60 , In 1 are the two baskets 50 . 60 in the interior 4 of the body 2 retracted.

The upper crockery basket 60 is in a known manner via a merely horizontally movable pullout guide in the interior 4 stored. The lower crockery basket 50 is about an application according sliding sliding mechanism in the body 2 stored, which is a retraction of the lower crockery basket 50 and then a subsequent pivoting allows. The sliding swivel mechanism comprises a swivel mechanism 10 and a pullout guide 20 ,

The retracted and raised state of the lower dish rack 50 is in the 2 shown. The lower crockery basket 50 is raised to approximately the same height as the upper dish rack 60 , In this position is a simple and back-friendly loading and unloading of the lower crockery basket 50 possible.

In the 3 to 5 and 6a, 6b 7a, 7b and 8a to d show a detail of a first exemplary embodiment of a slide-type pivoting mechanism according to the present invention, wherein different positions of the sliding pivoting mechanism are shown by way of example during the course of a lifting operation. A second and a third embodiment of an according to the application sliding pivot mechanism are in the 9a-12d respectively. 13a-14b shown.

In the description, terms such as above, below, left, right refer exclusively to the exemplary representation chosen in the respective figures. The terms front and back are generally related to a direction of extension of the pullout guide of the sliding pivot mechanism. The front side is in the pull-out process rushing forward, the user facing side.

It is noted that the illustrated sliding pivot mechanism, for. B. in the in the 1 and 2 reproduced dishwasher 1 or more generally such a household appliance can be used, as well as in a piece of furniture. The in the 1 and 2 bottom basket shown 50 represents an example of a tray that can be corresponding to a Gargutträger and / or a (shelf) floor in other applications.

In the 3 to 5 and 6a to 8a the sliding pivot mechanism of the first embodiment is shown in different operating positions each in a complete side view. As a rule, for synchronous lifting and lowering and extending the lower crockery basket 50 two mirror-inverted sliding swivel mechanisms on each side of the lower dish rack 50 intended. In the 3 to 5 and 6a, 6b . 7a . 7b and 8a to d is in each case only a sliding pivot mechanism with a portion of the dish rack 50 shown.

The respectively assigned 6b to 8b shows a part of the 6a to 8a in an enlargement. For those in the 8a and b specified fully swung and extended position is also in the 8c another side view and in the 8d an isometric view shown.

For reasons of clarity, all elements are not provided with reference numerals in all figures. In all figures, however, like reference numerals designate like elements.

In the 3 . 4 and 5 First, an extract sequence of the sliding pivot mechanism is shown, in which the dish rack 50 occupies different positions: a fully retracted position in 3 , a fully extended position in 5 and an intermediate position in 4 ,

The swing mechanism 10 includes a base plate (mounting plate) 11 with which the illustrated sliding pivot mechanism can be secured in the interior of the body, for example on the inside of the side wall 3 of the body 2 according to the 1 and 2 ,

At the base plate 11 are two swivel arms 12 . 13 swiveling in joints 121 respectively. 131 connected. The respective free end of the swivel arms 12 . 13 is with a carrier 15 in the joints 122 and 132 connected. The joints 121 and 131 are in the same direction and at the same distance as the joints 122 . 132 so that a parallel guide for the wearer 15 opposite the base plate 11 is formed. To distinguish the two pivot arms 12 . 13 below as the first pivot arm 12 , also carrying arm and second swivel arm 13 , also called control arm.

At the control arm 13 is a locking lever 14 in a joint 141 arranged, at its free end a locking pin 142 wearing. The function of the locking lever 14 or the locking pin 142 will be explained in more detail below.

The pullout guide 20 is present a full extension with a guide rail 21 , a middle rail 22 and a running track 23 , The guide rail 21 is with the carrier 15 connected, whereas the running rail 23 the filing, here the lower dish rack 50 wearing. When pulling out the dish rack 50 In essence, the track moves 23 opposite the middle rail 22 , in addition to the guide rail 21 is movable to the crockery basket 50 completely remove from the body of the dishwasher.

While pulling out the dish rack 50 from the fully retracted position ( 3 ) to the fully extended position ( 5 ) is the pivoting mechanism 10 blocked. This is due to the interaction of the locking pin 142 with a locking plate 151 achieved in 7b easy to recognize.

The 7b shows the area of the carrier 15 from the inside, ie from the direction of the dish rack 50 , In this illustration, it can be seen that the locking plate 151 a correspondingly designed area of the carrier 15 is, being the hinge 132 in the area of the locking plate 151 is arranged. The locking plate 151 has a circular curved portion on which the locking pin 142 while panning along.

The side is on the locking plate 151 a locking nose 152 formed and in the upper area a locking groove 153 , In the in the 3 to 5 shown pivot state in which the pivoting mechanism 10 is completely lowered, is the locking pin 142 below the locking nose 152 positioned and is held in this position spring force. For this purpose is between the control lever 13 and the locking lever 14 formed a spring not visible here. The same function that the locking nose 152 holds in the lower pivot state, meets the locking groove 153 for the upper swing state.

At the crockery basket 50 is at its rear end a guide element 30 mounted, which in a lower area a nearly vertical stop 32 provides. The guide element 30 may be made of plastic, for example, and to the dish rack 50 be clipped. In alternative embodiments, the guide element 30 also directly on the track 23 be attached.

For a complete excerpt of the dish rack 50 in the lower pivot position, a partial section of the stopper runs 32 of the guide element 30 against the locking pin 142 and pushes the locking pin 142 with it under the locking nose 152 out, whereby the blocking of the pivoting movement is canceled. This section of the stroke 32 can be sharp-edged, rounded or flat.

Another move on the crockery basket 50 leads to the lifting of the lock to pivot the pivot arms 12 . 13 and thus a lifting of the dish rack 50 ,

An initial stage of this panning is in the 6a and in magnification in the 6b shown. In addition to the function of unlocking the Schwenkarretierung takes over the guide element 30 in the subsequent pivoting another function: It represents a first obliquely, then substantially vertically upwardly extending guide curve 31 ready, which is open to the bottom and the front. The guide curve is present as a slot in the guide element 30 educated. In the fully extended position of the dish rack 50 is the opening of the guide curve 31 immediately behind a guide pin 124 positioned on a boom 123 is attached, starting from the first pivot arm 12 protrudes forward (relative to the lower pivot position of the first pivot arm 12 ). When lifting the dish rack 50 threads the leader pin 124 in the guide curve 131 one. This initial state of threading is in the 6a and 6b shown.

The 7a and 7b show the further lifting of the crockery basket 50 , For example, in a pivot state of about 45 ° of the pivot arms 12 . 13 , The guide curve 31 forms together with the guide pin 124 a coupling device. By threading the guide pin 124 in the guide curve 31 is the sliding movement of the pullout guide, in particular the position of the running rail 23 and thus the dish rack 50 coupled to the pivoting movement. Due to the positioning of the guide pin 124 opposite the joint 122 retracts the guide pin 124 opposite the joint 122 with respect to its horizontal position when pivoting the swing mechanism 10 back. Accordingly, the crockery basket 50 opposite the joint 122 withdrawn.

In addition, the movement of the dish rack 50 by the shaping of the guide curve 31 to be influenced. In sum, this can be achieved with the dish rack 50 when swinging the swing mechanism 10 not or only slightly further extends than in its maximum extension position in the lower pivot position. It can be prevented so that a loaded crockery basket 50 exerts an excessive tilting moment on the dishwasher, which can lead to tilting of the device especially in free-standing, not fixed under a worktop dishwashers. Next it prevents that Drop leftovers and liquids onto a kitchen floor in the area in front of the opened door of the dishwasher.

In the 7a is also a hitherto not visible or not shown Auszugsdämpfer 70 recognizable, which dampens the pivoting movement. This can be designed with an internal energy storage, so that a certain weight compensation of the dish rack 50 takes place and a pivoting possible in both directions possible without force.

In the 8a to d is the swing mechanism 10 then shown in its upper pivot state. Again, they are 8a and 8b Overall or detail views from one side, here from the inside of the sliding swivel mechanism, ie from the side of the dish rack forth. The 8c represents the same detail view as 8b only viewed from the outside.

8d gives an isometric view from obliquely outward front on the outside of the sliding swivel mechanism again.

In the 8a to d is to recognize on the one hand that the locking pin 142 in the locking groove 153 is engaged, and thus the pivoting mechanism 10 locked in the illustrated upper state. Due to the opposite of the carrier 15 pulled back the dish rack 50 through the guide pin 124 and the guide curve 31 has the locking pin 142 in the effective range of unlocking 40 emotional.

The unlocking 40 includes a confirmation lever 41 , which is bow-shaped on the opposite side of the dish rack 50 is guided and there also forms an actuating lever of an identically constructed unlocking the local sliding pivot mechanism. An actuation of the actuating lever 41 is via an intermediate lever 42 on a release lever 43 transfer that in a joint 431 is pivotally mounted. The release lever 43 includes with its free end the locking pin 142 hook-shaped. With a lower stop edge 432 of the release lever 43 is the locking pin when pressing the bracket 142 raised and thus out of the locking groove 153 lifted, so the swing mechanism 10 pivoted and the dish rack 50 can be lowered again. The operating lever 41 is through a holder 44 which also carries the dish rack 50 in its front area with the running track 23 coupled.

Should the crockery basket 50 be drained and pushed back into the body, the figure sequences are correspondingly run in reverse order.

When swinging down the dish rack 50 This first drives opposite the carrier 15 through the interaction of the guide pin 124 in the guide curve 31 until it reaches the lower, fully extended position.

In this position, the guide pin 124 also from the guide curve 31 released, so that a retraction of the dish rack is possible. Furthermore, the locking pin locked 142 behind the locking nose 152 the locking plate 151 so that another pivoting movement is blocked.

It is noted that an alternative way of unlocking the blocked pivotal movement is by lifting the locking pin 142 from the locking groove 153 in the upper position of the dish rack 50 also over the crockery basket 50 can be done by yourself. This can, for example, a small range of motion of the guide pin 124 in the guide curve 31 be admitted. A suitably positioned stop edge 432 lifts when moving the dish rack 50 in this scope the locking pin 142 from the locking groove 153 on, whereby the pivoting movement is released.

Hereinafter, a second embodiment of an application according sliding sliding mechanism in connection with the 9a to 12d described. In these figures, like reference characters designate the same or equivalent elements as in the first embodiment. For the sake of clarity again all elements are not provided with reference numerals in all figures.

The 9a . 10a . 11a . 12a show the sliding swivel mechanism respectively in a side view in different sliding or pivoting positions: 9a shows the fully lowered and retracted position, 10a the lowered and extended position, 11a a partially raised position and 12a the completely raised position. In the respectively assigned 9b . 10b . 11b and 12b are individual components of the sliding pivot mechanism in each case a side view isolated shown in the respective position.

In the basic structure, the sliding pivot mechanism of the second embodiment corresponds to that of the first embodiment. Unless otherwise indicated below, reference is hereby made explicitly to the comments on the first exemplary embodiment with regard to the construction.

Also in the second embodiment is a retraction of the lower dish rack 50 when swinging the swing mechanism 10 intended. Again, retraction is achieved by having a guide pin in a guide curve 31 a guide element 30 engages that on the track 23 or alternatively at the lower basket 50 is mounted.

Further, in the second embodiment, as in the first embodiment, a locking of the pivoting movement with retracted lower dish rack 50 provided, as well as a determination of the pivoting movement after pivoting. The locking must be via the actuation of the operating lever 41 unlocking 40 be solved manually before the lower dish rack 50 can be swung down again. For this purpose, as in the first embodiment, a locking pin 142 on a locking lever 14 , the swivel arm 13 hinged, present. The locking pin 142 lies in front of a locking nose 152 or in a locking groove 153 one on the carrier 15 trained locking plate 151 and thus blocks the pivoting movement.

In contrast to the first embodiment, however, is the locking pin 142 at the same time the guide pin, in the first embodiment by the reference numeral 124 is marked. As a result, only a single pin is needed that performs both functions - locking the pivoting movement and retracting the lower dish rack 50 - holds.

As 9b shows lies in the fully lowered and retracted position of the lower crockery basket 50 (see. 9a) the locking pin 142 under the locking nose 152 , whereby the pivoting movement is initially blocked. When pulling out the lower crockery basket 50 (see. 10a) in the fully extended position drives a stop edge of the guide element 30 sitting at the dish rack 50 is attached, against the locking pin 142 and raise him in front of the locking nose 152 , whereby the pivoting movement is released.

When swinging up the dish rack 50 (see. 11a) becomes the locking pin 142 due to the movement of the swivel arm 13 (and thus also the locking lever 14 ) raised. The stop edge of the guide element 30 goes up into the leadership curve 31 over, causing the locking pin 142 in the guide curve 31 enters and thus additionally the function of the guide pin 124 occupies according to the first embodiment.

Due to the curved shape of the guide curve 31 guides the movement of the locking pin 142 during the pivoting movement to a retraction of the lower crockery basket 50 , If the dish basket 50 completely swung up (cf. 12a) has the locking pin 142 on the one hand, the end of the guide curve 31 reaches and snaps to the other in the locking groove 153 one, causing the crockery basket 50 is found in the raised position. The guide curve 31 is in its end so continued downward that the locking of the locking pin 142 in the locking groove 153 is possible.

For swiveling down and inserting the lower crockery basket 50 will go through the sequence described above backwards. First, however, must do this manually by pressing the operating lever 41 the locking pin 142 from the locking groove 153 be lifted.

This process is in the 12c and 12d shown. 12c shows similar to 12b the carrier 15 and the guide element 30 and the operating lever 41 , In 12d is the arrangement of 12c without the carrier 15 played. The guide element 30 is shown transparently to the components of the unlocking 40 behind the guide element 30 lie, make visible.

As the 12d shows, the movement of the operating lever 41 via an intermediate lever 42 on a release lever 43 transferred, with a stop edge 432 under the locking lever 142 matured. By pivoting the operating lever 41 in the direction symbolized by the arrow becomes the stop edge 432 raised and according to the locking lever 142 from the locking groove 153 lifted, whereby the pivoting movement is released.

In the 13a, b and 14a, b is a third embodiment of an according to the application sliding pivot mechanism shown in two different extension positions. The 13a and 13b show the sliding pivot mechanism in a lower and fully inserted state, whereas the 14a and 14b show the sliding pivot mechanism in a lower and fully extended state.

In the 13a and 14a is the sliding swivel mechanism used in a dishwasher 1 each shown in an isometric view. The sliding swivel mechanism carries a lower dish rack 50 , In the dishwasher 1 is also in the upper dish rack 60 in the retracted position. The 13b and 14b show the sliding swivel mechanism in the respective position with the lower dish rack 50 separately from the dishwasher 1 in each case a side view.

With respect to the basic structure is on the sliding pivot mechanism according to the above referenced embodiments described. Different is the angular position of the pivot arms in the slide-swing mechanism reproduced here 12 . 13 the swing mechanism 10 in the lower position of the sliding swivel mechanism. In the embodiments shown above, the pivot arms 12 . 13 in the lower position of the dish rack 50 essentially vertical. By this configuration, a maximum stroke between the lower position and an upper position in which the pivot arms are aligned horizontally possible.

In the in the 13a to 14b the embodiment shown, the pivot arms extend 12 . 13 inclined in the lower pivot position at an angle of about 20 degrees with respect to the vertical forward. In this initial angular position is the same length of the pivot arms 12 . 13 a slightly smaller stroke of the lower rack 50 achieved upwards. For this is the offset that the carrier 15 on which the pullout guide 20 is attached, makes the pivoting forward, significantly lower. Accordingly, the coupling device, over which the running rail is moved during the pivoting relative to the guide rail, only need to perform a smaller travel path. The retracting guide curve 31 The coupling device can thus have a less steep pitch, which makes it easier to achieve a smooth and, if possible, force-free movement.
