DESCRIPTION

furniture element

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

Furniture elements such as shelves or shelves, where an inner body or a support plate is arranged movably in rotation and translation on or within an outer body, are for example known from document JP 10318669 or document DE 102017106170. A1.

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

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

In the case of shelves there is often the problem of, on the one hand, protecting the objects stored on them from dirt and, on the other hand, allowing them to be easily accessible. In the case of larger and/or taller furniture elements, in particular wall cabinets, sideboards or the like, it is also necessary to sufficiently support the rotation movement in the area of the cover plate of the furniture element. The placement of an additional rotation-translation bearing in the area of the cover plates is particularly difficult due to larger tolerances and a lack of rigidity of the individual components of the furniture element, so that in an additional rotation-translation bearing In this type, the bearing elements installed there are no longer guided in the support grooves provided for this.

Such furniture elements, in which additional functional elements for supporting or guiding the rotary movement are arranged in the region of the cover plates, are known from GB 412648 A, US 4 392628 A or WO 88/01483. A1.

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

The object of the present invention is to create a furniture element with an outer body and an inner body, which is mounted movably with respect to it by means of a rotation-translation bearing, which allows a reliable rotation-translation movement, as well as as a simple integration of additional functions.

This object is achieved by a furniture element with the characteristics of claim 1.

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

The rotation-translation 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 configured as a functional plate with a first guide rail integrated therein and at least one functional element integrated therein.

A guide element projecting into the first guide rail is arranged on the cover plate of the outer body and can be moved along the guide rail and interacts with the functional element upon reaching it.

The functional element is configured as self-retracting, self-extending or central retracting, or as at least one ejection element or at least one shock-absorbing element.

While a self-retraction or a self-extension is normally arranged in an end position of a predefined movement, as an alternative or additional functional element a central retraction can also be arranged in an intermediate position of the first or second guide rail to form a self-retraction in an intermediate position predefined, from which a subsequent movement can be made to a final position.

These central retractions are used, for example, on the central doors of 3-door sliding wardrobes to define an exact central position. The retraction function can be performed in both directions and shock absorbers can also be used to slow the movement. The technical structure of such a central retraction can be extracted, for example, from EP 2333218 A1 or EP 2744963 A1.

By providing a functional plate with a first guide rail integrated therein and at least one functional element integrated therein in the area of the cover plates, sufficient lateral guidance of the inner body on the stationary outer body is achieved, thereby supporting the translation-rotation movement of the inner body made possible by the translation-rotation bearing.

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 dependent claims.

According to an advantageous development of the invention, the functional plate has a second guide rail into which another guide element arranged on the cover plate of the outer body protrudes. With a second guide rail and such 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 housing formed in the cover plate of the inner body, the housing being open towards the cover plate of the outer body.

This allows for easy mounting and easy exchange possibilities to convert or retrofit the functional board with functional elements.

According to a variant embodiment, near one end of the first guide rail, a functional element is housed in a first recess of the functional plate, the ends of the first guide rail being joined together by a second recess in which a deviation element.

The deflection element is preferably configured as a rocker arm.

According to a preferred embodiment variant, the guide element is configured as a pin, bolt or wheel or ball bearing, so that in the case of a guide element configured as a pin or bolt it can slide in the guide rail, while in the case of a guide element configured as a wheel or ball bearing and also in the case of a wheel or ball bearing that rests on the guide rail only has a rolling friction effect and, therefore, the translational movement -rotation of the inner body with respect to the outer body can be carried out almost without resistance.

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

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

This makes it possible to subsequently introduce such a functional element on the functional plate as a retrofittable functional element.

According to another preferred embodiment variant, the inner body can be moved with respect to the outer body from a first functional position to a second functional position rotated at a predetermined angle with respect to the initial position, the bottom plates and the bottom plates. inner body cover and outer body are aligned with each other in matching geometries in both functional positions.

This makes it possible in particular to adjust the furniture element in combination with other furniture elements in different functional positions, without the furniture element taking up another space area.

In the following description of the figures, terms such as up, down, left, right, front, behind, etc. refer exclusively to the exemplary representation and position selected in the respective figures of the furniture element, the outer body, the inner body, the cover plate, the bottom plate, the guide rail, the guide elements and the like. These terms should not be understood as restrictive, i.e. these relationships may change due to different working positions or mirror symmetrical design or the like. In Figures 1a, 1b and 2, the reference number 1 collectively indicates a variant embodiment of a furniture element according to the invention. The furniture element 1 has an outer body 2 and an inner body 3, which is movably mounted relative thereto through a rotation-translation bearing 4 (shown in Figure 3).

As especially shown in Figures 2 and 3, the outer body 2 and the inner body 3 respectively have a bottom plate 21, 31 and a cover plate 22, 32. The inner body 3 also has two side walls 33, 34 connected to the bottom plate 31 and the cover plate 32.

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

In this case, other shapes are also conceivable, such as in particular a rectangular shape with side edges of different lengths or another polygonal shape.

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

The rotation-translation bearing 4 is arranged, as shown in Figure 3, between the bottom plate 21 of the outer body 2 and the bottom plate 31 of the inner body 3. The rotation-translation bearing 4 preferably has several grooves rolling grooves 41, in which rollers or rolling balls are guided, the rolling grooves 41 being designed in such a way that they allow a rotational movement of the inner body 3 with respect to the outer body 2 at a predetermined angle, in the example of embodiment illustrated here allow in particular 180°.

The rotation-translation bearing 4 also has a support plate 42 with a slot 43, through which a translational movement of the inner body 3 with respect to the outer body 2 in the direction A shown in Figure 3 is enabled. About the basic structure and how it works

For such a rotation-translation bearing 4, reference is made by way of example to document DE 102017 106170 A1, in which a rotation-translation bearing 4 of this type is described in detail.

As especially shown in Figures 1b and 2, 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 configured here as a separate plate, which It is fixed in a housing 35 formed in the cover plate 32 of the inner body 3. The housing 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 segment of the cover plate 32 of the inner body 3.

In all embodiment variants shown in the figures, the functional plate 5 has integrated a first guide rail 6 and a second guide rail 7. The guide rails 6, 7 are configured as grooves that are applied, 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 guide rail or more than two guide rails. The functional plate 5 is preferably made as a plate of wood or of a wood or plastic composite material, into which such recesses 6, 7 and other recesses 51, 52, 54 or holes 53 can be easily inserted. The holes 53 serve to fix the functional plate 5 to the cover plate 32 of the inner body 3, in particular by screwing.

The additional cutouts 51, 52, 53 serve to accommodate

functional elements 9, 9'. The functional element 9.9' that can be used in this case is a self-retraction, a self-extension, a central retraction, an ejection element or a damping element. Other configurations of such functional elements are also conceivable.

At least one guide element 8 is arranged on the cover plate 22 of the outer body 2, which protrudes into the first guide rail 6 and can be moved along the guide rail 6 and interacts with the functional element 9 upon reaching it.

The guide element 8 is preferably configured as a pin, bolt or as a wheel or ball bearing. The first guide rail 6 is preferably configured as an open curved rail with an elliptical or oval shape, which runs parallel to the plane of the functional plate 5.

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

A damping element allows the inner body 3 to be damped to a functional position predetermined by the ends 61,62 of the guide rail 6.

An ejection element allows an opening movement of the inner body caused by the ejection element by slightly pressing the side wall 33, so that after the opening movement has taken place in a slightly open position of the furniture element 1, such as shown in Figure 6, a user can intervene in the furniture element 1 and therefore by pressing against an interior of the side wall 33 or by pulling a front edge of the side wall 33, the interior body 3 can be moved manually more in the opening direction.

The functional activation of this functional element 9 takes place, as shown in Figure 5, by the guide element 8 used as an activator for the functional element 9. Figure 5 shows the guide element 8 removed from the end 61 of the first guide rail 6. through the functional element 9 configured as an ejection element. The position of the inner body 3 corresponds approximately to the representation in Figure 6.

In the variant embodiment shown here, the guide element 8 is configured as a wheel, which in its displacement movement shortly before reaching the end 61, 62, in the exemplary representation in Figure 5, upon reaching the first end 61 of the first guide rail 6, is pressed 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 activated in the case of a damper or pretensioning in the case of an ejector element by pressing the pin 92 when retracting the guide element 8 towards the end 61 of the first guide rail 6.

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

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

A variant embodiment of this type is shown in Figures 7 to 10. In this variant embodiment, in addition to the functional elements 9 provided in the first guide rail 6, another functional element is housed at one end 71 of the second guide rail 7. 9' in a notch 54 intended for its accommodation.

The functional element 9' is configured here as a self-retracting device, with a base body 91' in which a mechanism coupled to a driver 92' is housed. When this mechanism is activated by approaching the guide element 8 to the first end 71 of the second guide rail 7, as shown in Figure 8, the driver 92' grasps the guide element 8 and, as shown in Figure 9, pulls it towards the first end 71 of the second guide rail 7, whereby the inner body 3 moves to the closed position shown in Figure 1a.

Alternatively or additionally, a corresponding functional element 9' may also be arranged at the second end 72 of the second guide rail 7 to form a self-extension and correspondingly support a movement towards an opening position of the inner body 3.

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

If the introduction of such a functional element 9, 9' into the functional plate 5 is only planned at a later time as a retrofittable functional element, as shown by way of example in Figure 10, a cover 11 can be inserted in the recess 54 provided for this purpose instead of the functional element, so as not to impair the function of the other functional elements used in the functional plate 5 or, in the example of embodiment shown, to limit the end 71 of the second guide rail 7 to its dimensions without the notch 54. In an alternative embodiment variant to that described with reference to Figures 4 to 6, shown in Figures 11 and 12, only one of such functional elements 9 is embedded in a notch 51, which joins one of the ends 61,62 of the first guide rail 6.

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

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

On the rear side of a wing 102 of the deflection element 10 remote from the coupling element 104, the pin 92 of the functional element 9 rests, protruding into the recess 52 of the functional plate 5, which serves to house the deflection element 10. .

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

In this way, the wing 102 is pressed against the pin 92 of the functional element 9 and pressed into the housing 91 of the functional element 9 when the guide element 8 reaches the first end 61 of the first guide rail 6, as shown in the Figure 12.

If, on the other hand, the guide element 8 moves in the direction of the second end 62 of the first guide rail 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 with this the functional element 9 is also activated.

The guide rails 6, 7 and the translation-rotation bearing 4 are specially designed in such a way that the inner body 3 can move with respect to the outer body 2 from a first functional position to a second functional position rotated at a predetermined angle with with respect to the initial position, where, in both functional positions, the bottom plate 21, 31 and the cover plate 22, 32 of the inner body 3 and the outer body 2 are aligned with each other in coincident geometries.

Figure 1 shows a closed position as the first functional position of such a furniture element 1, in which the interior space 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.

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

As the rotation-translation movement of the inner body 3 with respect to the outer body 2 continues, the inner body 3 first reaches the second functional position shown in Figure 13, also called here semi-open position, in which the interior of the furniture 1 is accessible from the side.

As the rotation-translation movement of the inner body 3 with respect to the outer body 2 continues, the inner body 3 finally reaches the third functional position shown in Figure 14, also called the opening position here.

In this open position, the inner body 3 rotates 180° with respect to the outer body 2 and is once again completely housed 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 inner space of the inner body 3 is accessible from two open sides.

The depth of the guide rails 6 and 7, which are configured here as slots, and the length of the guide elements 8 also make it possible to compensate for manufacturing tolerances, as well as possible deformations of the outer body 2, which exerts a weight force through of the inner body 3 and the objects stored therein on the bottom plate 21 of the outer body 2, which may cause the bottom plate 21 to deform slightly vertically downward, especially when the inner body is in the maximum extended position of the outer body 2.

Thanks to the depth of the guide rails 6 and 7 configured as grooves and the length of the guide elements, safe guidance of the inner body 3 with respect to the outer body 2 is also reliably guaranteed in this situation.

Since the guide rails 6 and 7 only require a small amount of space on the functional plate, sufficient space remains 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, sideboard, furniture element of a kitchen island or the like.
