Description

The present invention relates to a furniture element according to the preamble of claim 1.

Furniture elements such as shelves or shelves, in which an inner body or a support plate is arranged on or in an outer body in a rotationally and translationally movable manner, are, for example, from JP 10318669 or the DE 10 2017 106 170 A1 known.

To carry out such a translation-rotation movement, DE 10 2017 106 170 A1 a translational rotation bearing is used, which essentially has two plates with running grooves formed therein, in which rolling rollers or rolling balls are guided, the running grooves being designed in such a way that they allow a rotational movement of one (upper) plate relative to the second (lower). ) Allow plate to a predetermined angle. In addition, a slot is provided in the upper plate, which allows translational movement of the plates relative to one another.

In particular, the support plate described in the last-mentioned publication has proven itself in practice.

With shelves there is often the problem of, on the one hand, protecting the items stored on them from dirt and, on the other hand, allowing the items to be easily accessible. In the case of larger and/or taller furniture elements, in particular wall cabinets, highboards or the like, it is also necessary to additionally support the rotational movement sufficiently in the area of the cover plate of the furniture element.

The attachment of an additional translational rotation bearing in the area of the cover plates is made particularly difficult by larger tolerances and a lack of rigidity of the individual components of the furniture element, so that with such an additional translational rotation bearing, the rolling bearing elements installed therein are no longer guided in the bearing grooves provided for this purpose.

Such furniture elements in which additional functional elements in the area of the cover plates to support or guide the rotational movement are arranged are from the publications GB 412 648 A , US 4,392,628 A or WO 88/01483 A1 known.

In addition, the introduction of additional functionalities such as an ejection function to enable handle-free operation of the furniture element can only be integrated into such a translation-rotation bearing with great effort.

The object of the present invention is to provide a furniture element with an outer body and an inner body which is movably mounted relative thereto via a translational rotation bearing, which allows a reliable translational rotational movement as well as a simple integration of additional functions.

This task is achieved by a furniture element with the features of claim 1.

In the furniture element according to the invention, the outer body and the inner body have at least one base plate and one cover plate. The inner body has at least one side wall connected to the base plate and the cover plate.

The translational rotation bearing is arranged between the bottom plate of the outer body and the bottom plate of the inner body.

The cover plate of the inner body or a plate arranged between the cover plate of the outer body and the cover plate of the inner body is designed as a functional plate with a first guide track integrated into it and at least one functional element integrated into it.

Arranged on the cover plate of the outer body is a guide element which protrudes into the first guide track and can be moved along the guide track and interacts with the functional element when it is reached.

The functional element is designed as a self-retraction or self-extension or central retraction, or in the form of at least one ejection element or at least one damping element.

While a self-retraction or a self-extraction is usually arranged at an end position of a predefined movement, as an alternative or further functional element, a center retraction can also be arranged at an intermediate position of the first or second guide track in order to form a self-retraction into a predefined intermediate position, from which then further movement to an end position can take place.

Such center recesses are used, for example, on the center doors of 3-door sliding door wardrobes to define an exact center position. The retraction function can take place from both directions, and dampers can also be used to slow down the movement. The technical structure of such a collection of funds can, for example, come from the EP 2 333 218 A1 or from the EP 2 744 963 A1 be removed.

By arranging a functional plate with a first guide track integrated into it and at least one functional element integrated into it in the area of the cover plates, sufficient lateral guidance of the inner body in the stationary outer body is achieved, with which the translational-rotational movement of the inner body made possible by the translational-rotation bearing is supported .

In addition, the functional plate makes it possible to easily equip the furniture element with one or more additional functions.

Advantageous embodiment variants of the invention are the subject of the subclaims.

According to an advantageous development of the invention, the functional plate has a second guide track into which a further guide element arranged on the cover plate of the outer body projects. With such a second guide track and a second guide element, the guidance of the inner body relative to the outer body in the area of the cover plates is further improved.

According to an advantageous development of the invention, the functional plate is fixed in a receptacle formed in the cover plate of the inner body, the receptacle being open towards the cover plate of the outer body.

This enables easy assembly and simple exchange options for converting or retrofitting the functional plate with functional elements.

According to one embodiment variant, a functional element is accommodated near one end of the first guide track in a first recess of the functional plate, the ends of the first guide track being connected to one another by a second recess in which a deflection element is accommodated.

The deflection element is preferably designed as a rocker.

According to a preferred embodiment variant, the guide element is designed as a pin, bolt or wheel or ball bearing, so that in the case of a guide element designed as a pin or bolt, it can slide in the guide track, while in the case of a guide element designed as a wheel or ball bearing and also on a side edge The wheel or ball bearing that abuts the guideway only has a rolling friction effect and the translational-rotational movement of the inner body relative to the outer body can therefore be carried out with almost no resistance.

In a preferred development, the guide element is designed as an activator for the at least one functional element.

According to a further embodiment variant, at least one recess in the functional plate can be covered by a cover.

This enables such a functional element to be introduced into the functional plate at a later point in time as a functional element that can be retrofitted.

According to a further preferred embodiment variant, the inner body can be moved relative to the outer body from a first functional position into a second functional position rotated by a predetermined angle relative to the starting position, the base plates and the cover plates of the inner body and the outer body being aligned with one another in matching geometries in both functional positions.

This makes it possible, in particular, to set the furniture element in combination with other furniture elements in different functional positions without the furniture element occupying a different area of space.

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 furniture element, the outer body, the inner body, the cover plate, the base plate, the guide track selected in the respective figures , the guide elements and the like. These terms are not to be understood as restrictive, i.e. these relationships can change due to different working positions or the mirror-symmetrical design or the like.

In the Fig. 1a , 1b and 2 The reference number 1 denotes a total embodiment variant of a furniture element according to the invention. The furniture element 1 has an outer body 2 and an outer body 2 relative to it Translational rotation bearing 4 (shown in Fig. 3 ) movably mounted inner body 3.

Like especially in the Fig. 2 and 3 is shown, the outer body 2 and the inner body 3 each have a base plate 21, 31 and a cover plate 22, 32. The inner body 3 also has two side walls 33, 34 connected to the base plate 31 and the cover plate 32.

In principle, it would also be conceivable to connect the base plate 31 to the cover plate 32 via just one such side wall. In the embodiment variant shown here, the outer body 2 also has two side walls 23, 24. The base plates 21, 31 and the cover plates 22, 32 are designed with a square area in the embodiment variant shown here.

Other shapes are also conceivable here, such as in particular a rectangular shape with side edges of unequal length or another polygonal shape.

The at least one side wall for connecting the base plate 31 to the cover plate 32 is usually arranged approximately flush with an outer edge of the base plate 31 or the cover plate 32, but it is also possible in the sense of the invention to have the side wall at a distance or at an angle to the outer edge of the To arrange the base plate 31 or the cover plate 32.

The translational rotation bearing 4 is, as in Fig. 3 shown, arranged between the base plate 21 of the outer body 2 and the base plate 31 of the inner body 3. The translational rotation bearing 4 preferably has a plurality of running grooves 41 in which rolling rollers or rolling balls are guided, the running grooves 41 being designed in such a way that they allow a rotational movement of the inner body 3 relative to the outer body 2 by a predetermined angle, in this case illustrated embodiment in particular enable 180 °.

The translational rotation bearing 4 further has a bearing plate 42 with a slot 43, via which a translational movement of the inner body 3 relative to the outer body 2 in an in Fig. 3 indicated direction A. About the basic structure and how it works

Translational rotation bearing 4 is an example of the DE 10 2017 106 170 A1 referenced, in which such a translational rotation bearing 4 is described in detail.

Like especially in the Fig. 1b and 2 is shown, a functional plate 5 is arranged between the cover plate 22 of the outer body 2 and the cover plate 32 of the inner body 3. The functional plate 5 is designed here as a separate plate, which is fixed in a receptacle 35 formed in the cover plate 32 of the inner body 3. The receptacle 35 is designed to be open towards the cover plate 22 of the outer body 2.

It would also be conceivable to design the functional plate 5 as a section of the cover plate 32 of the inner body 3.

In all embodiment variants shown in the figures, the functional plate 5 has a first guide track 6 and a second guide track 7 integrated into it. The guide tracks 6, 7 are designed as grooves which are introduced, for example milled, into a surface of the functional plate 5 facing the cover plate 22 of the outer body 2.

However, it is also possible to provide only one guideway or more than two guideways
The functional plate 5 is preferably made as a wooden plate or plate made of a wood composite material or a plastic, into which such grooves 6, 7 and further recesses 51, 52, 54 or bores 53 can be introduced in a simple manner. The holes 53 serve to fasten the functional plate 5 to the cover plate 32 of the inner body 3, in particular by screwing.

The further recesses 51, 52, 53 serve to accommodate

Functional elements 9, 9`. The functional element 9.9' that can be used here is a self-retraction, a self-extension, a center retraction, an ejection element or a damping element. Other configurations of such functional elements are also conceivable.

On the cover plate 22 of the outer body 2 there is at least one projecting into the first guide track 6 and along the guide track 6 movable guide element 8 which interacts with the functional element 9 when it is reached.

The guide element 8 is preferably designed as a pin, bolt or as a wheel or ball bearing.

The first guide track 6 is preferably designed as an open curved track with an elliptical or oval-like shape that extends parallel to the plane of the functional plate 5.

As in Figure 4 is shown, a first recess 51 is formed on each of the ends 61, 62 of the first guide track 6, in which a functional element 9 designed, for example, as a damping element or as an ejection element is inserted.

A damping element enables the inner body 3 to be dampened into a functional position predetermined by the ends 61, 62 of the guide track 6.

By slightly pressing in the side wall 33, an ejection element enables an opening movement of the inner body caused by the ejection element, so that after the opening movement has taken place, the furniture element 1 is in a slightly open position, as shown in Figure 6 is shown, a user can intervene in the furniture element 1 and can manually move the inner body 3 further in the opening direction by pressing against an inside of the side wall 33 or by pulling on an end edge of the side wall 33.

The functional triggering of this functional element 9 takes place as in Figure 5 is shown, by the guide element 8 used as an activator for the functional element 9. Figure 5 shows the guide element 8 moved out of the end 61 of the first guide track 6 by the functional element 9 designed as an ejection element. The position of the inner body 3 corresponds approximately to the illustration in Figure 6 .

In the embodiment variant shown here, the guide element 8 is designed as a wheel, which in its traversing movement stops shortly before reaching the end 61, 62, in the exemplary illustration in Figure 5 upon reaching the first end 61 of first guide track 6 presses against a pin 92 of the functional element 9, which is in operative connection with a mechanism in a base body 91 of the functional element 9, the functional element 9 being pressed in when the guide element 8 is retracted into the end 61 of the first guide track 6 is triggered by a damper or preloaded by an ejection element.

If the inner body 3 is moved in a further movement so that the guide element 8 is moved from the first end 61 into the second end 61, the pin 92 of the functional element 9, which is arranged at the second end 62 of the first guide track 6, is correspondingly actuated . The pin 92 protrudes into the respective end 61,62 of the first guide track 6.

It is also conceivable to introduce a third recess 54 or several such third recesses 54 into the functional plate 5 in the area of the second guide track 7 and to insert a functional element 9 there.

Such an embodiment variant is in the Figures 7 to 10 shown. In this embodiment variant, in addition to the functional elements 9 provided on the first guide track 6, a further functional element 9 'is accommodated at one end 71 of the second guide track 7 in a recess 54 intended to accommodate it.

The functional element 9' is designed here as a self-closing mechanism, with a base body 91' in which a mechanism coupled to a driver 92' is accommodated. When this mechanism is activated by approaching the guide element 8 to the first end 71 of the second guide track 7, as shown in Figure 8 is shown, the driver 92 'engages around the guide element 8 and pulls it, as in Figure 9 shown, into the first end 71 of the second guide track 7, whereby the inner body 3 into the in Figure 1a shown closed position is moved.

Alternatively or additionally, a corresponding functional element 9 'can also be arranged at the second end 72 of the second guide track 7 in order to form a self-extension and accordingly support a movement into an opening position of the inner body 3.

Alternatively or additionally, a corresponding further functional element in the form of a central retraction can also be arranged at an intermediate position of the second guide track 7 in order to form a self-retraction into a predefined intermediate position, from which further movement into an end position can then take place.

If the introduction of such a functional element 9, 9 'into the functional plate 5 is only planned at a later point in time as a retrofittable functional element, as exemplified in Figure 10 is shown, instead of the functional element, a cover 11 can be inserted into the recess 54 provided for this purpose in order not to impair the function of the other functional elements used in the functional plate 5 or, in the exemplary embodiment shown, the end 71 of the second guide track 7 on its without the recess 54 to limit existing dimensions.

In one based on the Figures 4 to 6 alternative embodiment variant described, shown in the Figures 11 and 12 , only one such functional element 9 is embedded in a recess 51 which adjoins one of the ends 61, 62 of the first guide track 6.

In addition, a second recess 52 is inserted between the ends 61, 62 of the first guide track 6, in which a deflection element 10 is arranged. The deflection element 10, designed here as a mechanical rocker, makes it possible to save one of the two in the exemplary embodiment Figures 4 and 5 functional elements 9 shown.

As in Figure 11 is shown, the deflection element 10, designed here as a rocker, has wings 101, 102 which extend from an axis of rotation 103 and are fastened to the axis of rotation 103, on each of which a coupling element 104 is arranged in an articulated manner and its free end is inserted into one of the ends 61, 62 the first guideway 6 protrudes.

On the back of one wing 102 of the deflection element 10 facing away from the coupling element 104, the pin 92 of the functional element 9 rests, which protrudes into the recess 52 of the functional plate 5, which serves to accommodate the deflection element 10.

When the guide element 8 enters the area of the first end 61 of the first guide track 6, the guide element 8 presses against the coupling element 104 of the wing 102, as shown in Figure 11 is shown.

The wing 102 is thereby pressed against the pin 92 of the functional element 9 and presses it when the guide element 8 reaches the first end 61 of the first guide track 6, as in Figure 12 is shown in the housing 91 of the functional element 9.

If, on the other hand, the guide element 8 moves in the direction of the second end 62 of the first guide track 6, the guide element 8 presses against the other wing 101 of the deflection element 10, which leads to a movement of the wing 102 against the pin 92 of the functional element 9 and thus also the functional element 9 triggers.

The guide tracks 6, 7 and the translation-rotation bearing 4 are designed in particular in such a way that the inner body 3 can be moved relative to the outer body 2 from a first functional position into a second functional position rotated by a predetermined angle relative to the starting position, the base plate 21 being in both functional positions. 31 and the cover plate 22, 32 of the inner body 3 and the outer body 2 are aligned with one another in matching geometries.

This is exemplified in Fig. 1 a closed position is shown as the first functional position of such a furniture element 1, in which the interior of the furniture element is closed to the outside by the side walls 23, 24 of the outer body on the one hand and the side walls 33, 34 of the inner body on the other hand.

In order to make the objects stored in the furniture element 1 accessible, the inner body 3 is moved out of this closed position relative to the outer body 2.

As the translational-rotational movement of the inner body 3 continues relative to the outer body 2, the inner body 3 first reaches the in Fig. 13 shown second functional position, also referred to here as a half-open position, in which the interior of the furniture element 1 is accessible from one side.

As the translational-rotational movement of the inner body 3 continues relative to the outer body 2, the inner body 3 finally reaches the in Fig. 14 shown third functional position, also referred to here as the opening position.

In this open position, the inner body 3 is rotated by 180° relative to the outer body 2 and is again completely accommodated in the outer body 2. Since the side walls 33, 34 are now arranged close to the side walls 23, 24 of the outer body 2, the interior of the inner body 3 is accessible from two open sides.

The depth of the guide tracks 6 and 7, which are designed here as grooves, and the length of the guide elements 8 also enable compensation for manufacturing tolerances as well as any deflections of the outer body 2 that may occur, which exert a weight force on the base plate 21 of the inner body 3 and the objects stored therein Outer body 2 exerts, which can lead to the base plate 21 bending slightly vertically downwards, especially when the inner body is in the maximum position turned out of the outer body 2.

Due to the depth of the guide tracks 6 and 7 designed as grooves and the length of the guide elements, reliable guidance of the inner body 3 relative to the outer body 2 is also reliably ensured in this situation.

Since the guide tracks 6 and 7 only require a small amount of space in the functional plate, there is sufficient space left for the arrangement of one or more functional elements 9 in order to design the use of such functional elements 9 in an extremely variable manner.

The furniture element 1 can be used in particular as a wall cabinet, highboard, furniture element of a kitchen island or the like.
