Description

Sliding tilt mechanism of a cabinet of a piece of furniture or

Household appliance, furniture and household appliance

The present 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 according to the preamble of claim 1. The invention further relates to a piece of furniture and a household appliance with such a sliding pivot mechanism. A generic sliding pivot mechanism is known from DE 10 2012 107 993 A1. In the disclosed in this document sliding swivel mechanism is supported by means of a tension spring which acts on one of the pivot arms, the raising or lowering of the tray. This makes it possible to load or unload the tray in an upright position of the user that relieves the back muscles and the spine.

Such a sliding pivot mechanism has proven itself in practice. However, especially when loading the tray with relatively heavy objects, in particular with a total mass of more than 10 kilograms, the raising or lowering of the tray is difficult. The use of a tension spring with a higher spring rate is not sensible here, since such a tension spring would make it very difficult to lower the tray in the unloaded state.

Object of the present invention is to provide a sliding pivot mechanism of a shelf of a piece of furniture or household appliance, with the raising or lowering of the shelf is facilitated.

The stated object is achieved by a sliding pivot mechanism of a shelf of a piece of furniture or household appliance for removing or lifting the tray from a body of the furniture or household appliance with the features of claim 1. The stated object is further achieved by a piece of furniture having the features of claim 13 and a household appliance having the features of claim 14. The sliding swivel mechanism according to the invention has at least two on at least one of the side walls of the body with a first in the parallel to the plane of the side walls rotatable fixed and mutually spaced apart arranged pivot arms of a pivoting mechanism. At respective second ends of the pivot arms, respective guide rails of a sliding mechanism are pivotally fixed parallel to the plane of the side walls such that the guide rail is pivotable at least partially outside the body from a lowered position within the body to a raised upper position. The sliding pivot mechanism further comprises at least one linear rail slidable in the guide rail on which the tray is attached. The sliding pivot mechanism further includes a lever unit assisting in raising and lowering the pivot mechanism.

With a lifting and lowering the pivot mechanism support lever unit is a simple way and without changing the spring rate of a tension spring a simplified raising and lowering of the tray allows. Advantageous embodiments of the invention are the subject of the dependent claims.

According to an advantageous embodiment variant of the invention, the lever unit has two lever elements interconnected by at least one transverse web. The crosspiece serves as an operating handle. The lever elements can be formed at an angle.

The lever elements are shaped such that a raising and lowering of the tray with less effort compared to a conventional handle attached to the tray or by intervention in the tray itself is possible.

According to a further advantageous embodiment of the invention, the lever elements on a first leg and a second leg, wherein a first transverse web between the free ends of the short leg is arranged. The second leg is preferably designed so that the first transverse web at least in the lowered position or in the raised position or in an intermediate position above the tray positio- is defined. Particularly advantageously, the first crosspiece is positioned in any position above the tray.

As a result, the access to the crossbar is facilitated by a person insofar as that the crosspiece is positioned vertically higher than the tray itself, especially in the lowered position of the tray.

The lever elements are fixed according to a preferred embodiment, parallel to the plane of the side walls pivotally mounted on the running rail. The first leg has at its free ends preferably rolling or sliding elements with which the lever unit can be supported on a floor.

This can be additionally supported by pulling on the first crosspiece, the pivoting movement of the body upwards over the lever elements after pulling out the tray in its Schwenkstartstellung.

According to an alternative embodiment, the lever elements of the lever unit are aligned parallel to the plane of the side walls mounted on the pivoting mechanism.

The lever elements are preferably U-shaped and coupled for the pivoting movement with one of the pivot arms, so that here by pulling the first crossbar a favorable leverage is exploited to pivot the tray from its lowered position to the raised position.

Advantageously, the lever elements of the lever unit can be made longer than at least one pivot arm of the pivot mechanism in order to achieve a very advantageous lever ratio in the pivoting movement.

The lever elements can be made in one or more parts and rigidly connected to each other.

According to a further alternative embodiment variant, the lever unit has two lever elements which are pivotably fixed to the pivoting mechanism and whose ends spaced from the pivoting mechanism are pivotally connected to respective lifting elements which can be telescoped in the withdrawal direction and which are extendable and retractable with a drive unit. Such lifting elements, which can be driven by a drive unit, make it possible, in yet another alternative way, to support the lifting and lowering movement of the pivoting mechanism. According to an advantageous embodiment, rolling elements are also arranged at the spaced from the pivot mechanism ends of the lever elements, with which the lever elements are supported on a floor, so with relatively low driving force, reinforced by the leverage of the lever elements support the lifting and lowering movement made possible - light is.

The furniture according to the invention and the household appliance according to the invention are characterized by the sliding pivot mechanism described above. In an example designed as a flushing device household appliance is loaded and unloaded a lower tray, which is arranged in the lowered position in the lower region of the body and possibly below an upper tray with such a trained sliding pivot mechanism, as the shelf is not much easier only in a comfortable raised position is movable, but the method of storage in the raised position is made possible even with less effort.

Swing mechanics and

Figures 1 1 to 1 5 Figures 1 to 5 corresponding representations of another alternative embodiment of the sliding pivot mechanism.

In the following description of the figures, terms such as top, bottom, left, right, front, back, etc. refer exclusively to the exemplary representation and position of the sliding pivot mechanism, the tray, the pivot arms, the guide rail, the track, the lever unit, the lever elements 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 the figures 1 to 1 5 three different embodiments of a sliding pivot mechanism according to the invention are shown, with exemplary positions of the sliding pivot mechanism are shown in the course of a lifting operation.

Details of the structure of the sliding pivot mechanism and their operation are described in more detail in the aforementioned DE 1 0 201 2 1 07 993 A1, the content of which is hereby incorporated into this application for explaining numerous details of the sliding pivot mechanism.

As shown, for example, in FIGS. 2, 7 and 1 2, the sliding pivot mechanism essentially comprises two on the side walls 21 of the body 2 of a piece of furniture or household appliance 1 with a first end parallel to Level of the side walls 21 rotatably fixed and mutually parallel spaced pivot arms 51, 52 of a pivot mechanism 5 on.

For fixing to the side walls 21 of the body 2 are preferably plate-shaped side wall brackets 53 are provided, which in turn are fixed to the side walls 21 of the body 2. At the remote from the wall bracket 53 ends of the pivot mechanism 5, a guide rail 61 of a sliding mechanism 6 of the sliding pivot mechanism is fixed in each case parallel to the plane of the side walls 21 pivotally. As a result, the guide rails 61 held on the pivoting arms 51, 52 can be pivoted from a lower position within the body 2 into a raised upper position in front of the body 2.

The sliding mechanism 6 furthermore has a running rail 62, which can be displaced linearly relative to the guide rail 61, to which a tray 4 is fastened. As a result, the tray 4 from a completely retracted into the body 2 position for loading or unloading initially linear out of the carcass and then, as shown in Figures 3 to 5, for example, pivot in a raised position, in which a loading or Unloading is convenient to perform.

The sliding pivot mechanism is mounted in the embodiment shown in the interior 23 of a dishwasher designed as a household appliance 1. The sliding pivot mechanism serves to hold the lower tray 4 positioned below an upper tray 3.

In order to facilitate the raising or lowering of the tray 4, a lever unit 7 is arranged on the sliding pivot mechanism according to a first embodiment of the sliding pivot mechanism, shown in Figures 1 to 5.

This lever unit 7 has two angularly shaped lever elements 71 with a first leg 71 1 and a second leg 71 2. The L-shaped lever elements 71 are, as shown for example in Figure 2, connected to each other at the free ends of the second leg 712 of the lever members 71 by a transverse web 72. This transverse web 72 is positioned slightly above, in the retracted position of the tray 4, viewed in a vertical direction z, the front end of the tray 4 in the extension direction x. Accordingly, the second leg 71 2 of the lever elements 71 is dimensioned such that the first transverse web 72 is positioned above the tray 4.

The lever elements 71 furthermore have a first leg 71 1, wherein the free ends of the first legs 71 1 in the preferred embodiment variant shown here are connected to one another by a second transverse web 73 for stabilizing the lever unit 7.

For example, as can be seen in FIG. 3, the lever elements 71 are connected to the running rail 62 of the sliding mechanism 6 via a connecting element 76 and a pivot joint 75.

The first leg 71 1 extends from the rear in the extension direction x free end of the lever member 71 to the pivot 75. The second leg 71 2 extends from the pivot 75 to the front x in the extension free end of the lever member 71 and is designed at right angles. The second leg may also have other shapes.

When moving out of the tray 4 from a usable space 23 of the body 2, the lever unit 7 is first pulled out horizontally together with the tray 4 from the work space 23 of the body 2. For this purpose, the user can take the cross bar 72 instead of the tray 4 itself.

A premature lifting of the tray is thereby according to a preferred embodiment by a fixed to the rail 62 activator (not shown) operable on a locking mechanism to prevent simultaneous pivoting and sliding movement of the sliding mechanism 6 is prevented. For the operation of this locking mechanism, reference is made to DE 10 201 2 1 07 993 A1. After the tray 4 has reached its maximum pushed out of the body 2 position, the tray 4 can be raised via the pivot mechanism 5 in its upper position. This position is shown in FIG. An intermediate position is shown in FIG. As can be seen here, the upward pivoting of the tray 4 and the pivot arms 51, 52 of the pivot mechanism 5 is assisted by the user pulling the first cross bar 72 in the vertical direction z.

In this case, the free ends of the first leg 71 1 of the lever elements 71 are moved on a bottom 24 of the body 2 toward a support surface 81 on the inside of a flap door 8 of the household appliance 1. In order to enable a simple method of the lever unit 7 on the floor 24 and the support surface 81 of the flap door 8, 71 rolling elements in the form of rolling elements 74 are arranged at the free ends of the long leg 71 1 of the lever elements 74, with which the lever unit 7 on the ground 24 and the support surface 81 is movable and supportable.

Due to the pivotal mounting of the lever elements 71 on the rotary joint 75 causes pulling on the cross bar 72 in addition to a method of the rear ends of the lever elements 71 in the extension direction, a lifting operation of the tray 4 supporting force vertically upward in the direction z.

After reaching the maximum raised position of the tray 4, the first transverse web 72 is pivoted into a position close to the carcass above the tray 4, so that the first transverse web 72 does not hinder loading or unloading of the tray 4.

Figures 6 to 1 0 show a second embodiment of the sliding pivot mechanism. Here, in addition to a long leg 71 3 'and a short leg 714', the lever elements 71 'have a second short leg 71 5', which adjoins the rear end of the long leg 71 3 'in the extension direction x, so that the Lever elements 71 'are shaped approximately U-shaped overall.

Between the free ends of the front short leg 714 'in the extension direction x, a first transverse web 72' is also arranged here, which, as in the embodiment variant according to FIGS. 1 to 5, can be used as a handle by a user. The cross bar 72 'is also positioned above the tray 4 in this embodiment. The connection of the lever unit 7 'takes place here on the pivot mechanism. 5

For this purpose, as shown for example in Figure 7, the side wall bracket 1 2 provided with a sliding guide 54 ', along which in the extension direction x rear free end 71 6' of the second short leg 71 5 'during horizontal extension and retraction of the tray 4 is displaceable , If the tray 4 reaches its end position before the tray 4 is pivoted upwards, the free end 71 6 'of the second short leg 71 5' is coupled to one of the swivel arms 51, 52 of the swivel mechanism 5. The lever unit 7 'is rotatably fixed to the second pivot arm 52 in this position shown in Figure 8.

During the subsequent upward pivoting of the tray 4 and the pivot arms 51, 52 of the pivoting mechanism, by pulling the first transverse web 72 'in the vertical direction z, an upward pivoting of the pivoting levers 51, 52 is supported.

Due to the distance of the first crosspiece 72 'from the attachment point of the second short leg 71 5' on the pivot arm 52, in particular due to the long lever 71 3 'of the lever elements 71', a significant support of raising the tray 4 is possible with relatively little effort ,

The same applies to the subsequent lowering of the tray 4 in its lower position.

In the figures 1 1 to 1 5 a further advantageous embodiment of a sliding pivot mechanism according to the invention shown. In this embodiment, the lever unit 7 "is also rotatably fixed to the pivoting mechanism 5.

As can be seen particularly well in FIGS. 14 and 15, the lever unit 7 "shown here has two lever elements 71" which are pivotably fixed to the pivoting mechanism 5 and which are telescoping at their ends spaced from the pivoting mechanism 5 with respective pull-out directions x Hubele- ments 72 "pivotally connected.

The lifting elements 77 "are extendable and retractable via a drive unit 78". The drive unit 78 ", designed as an electric motor, for example. Det, is preferably set in a pull-out x rear portion of the work space 23, near the rear wall 22 at the bottom 24 of the body 2.

The connection of the lifting element 72 "with the lever element 71" also takes place via a rotary joint 75 "., In order to support the lifting operation of the tray 4 when lifting in its raised position, is at the ends of the lifting element 77" in the region of the rotary joint 75 Each of the lever elements 71 "is arranged a rolling element in the form of a rolling element 74" is, on the inside 81 of the flap door 8 resting rolling elements 74 "the lever member 71" down from.

As a result of the length of the lever element 71 ", the lifting operation of the tray 4 is thereby assisted with relatively little effort by the swivel mechanism 5. As shown in Figure 1 2, the lifting elements 77" are preferably telescoping rods with a plurality of rod elements 771 ", 772 ", 773" and 774 "trained.

In the retracted position of the shelf in the body 2 of the furniture or household appliance 1, the lifting elements 77 are "completely or almost completely retracted into the drive unit 78".

In this variant can be dispensed with a first crosspiece for operation by the user, for example, when operated by a switch or by remote control.

The use of such a sliding pivot mechanism is not limited to a household appliance. It is also conceivable use in office, doctor's office, living or kitchen furniture with shelves that can be equipped for loading and unloading with such a sliding swivel mechanism. In addition, the sliding pivot mechanism can be equipped with at least one damping element, for example a fluid damper, in order at least partially to ensure a damped movement of at least one shelf
