EP3085878B1 - Furniture, in particular cupboards - Google Patents

Description

The invention relates to a piece of furniture, in particular cupboard furniture, according to the preamble of claim 1, as it for example EP 1 635 023 B1 is known.

Furniture of the generic type has lamellar doors, in particular slatted mats and the like, and is usually formed by individual lamellar door elements linked to one another. The door with the slats is guided in a guide on both sides of an opening to be closed. When opening the furniture, the door is guided along the guide and runs with increasing degree of opening in the vicinity of a side wall of the cabinet inside the cabinet.

Due to the geometry, this louvered door must pass through a right angle in a deflection region where it exits from the interior of the cabinet to the front. The consequence of this is that at least the last door element or in the opening direction leading slat in fully closed furniture in the closed state is oblique or not flush with the side of the cabinet, so that on the front of the cabinet, a gap is created by lateral veneers must be laminated. Such laminating veneers are extremely disturbing to the overall impression. This is achieved in the prior art by letting the last blade fold forward in the closed state. In the known furniture, this is achieved by a complex mechanism in which two guides in each bounding the opening of the furniture Side cheeks are provided, wherein the lamellae are guided in a first guide and the chain of lamellae has at its end a fitting which is additionally guided in a second guide and receives at least one lamella. A second guide runs parallel to the first guide, but changes in the pivoting range of the door elements to the front of the cabinet towards their course so that the fitting passes on a relatively short covered distance a large swivel range. As a result, the last lamella works to the front of the furniture, so that an inclination of the lamella is avoided and as a result, no additional veneering is required.

This solution has proven itself in practice, but on the one hand requires matching fittings and on the other hand corresponding double guides.

Object of the present invention is therefore to provide a piece of furniture of the type mentioned, in which also folds the last slat forward and their inclination is avoided, the mechanism but compared to the known solution greatly simplified and especially for blind slats, especially those Plastic, is suitable.

This object is achieved by a piece of furniture having the features of claim 1. Advantageous embodiments can be found in the subclaims.

The furniture according to the invention, which in particular has the shape of a cabinet furniture, has an opening and on both sides of the opening existing guides in which a slat door designed in particular as a slatted mat is slidably disposed. The louver door has in turn articulated lamellae. Next, a deflection is provided. This is designed so that the slats when moving the slatted door in an opening opening making opening position in the opening direction are guided successively through the deflection and thereby guided by a radius.

According to the present invention, at least the lamella leading in the opening direction, that is to say the lamella, which must first be guided through the deflection region when opening, has a first magnet. Furthermore, the deflection region has at least one second magnet connected to the furniture.

These two magnets, one on the slidable louver door, the other on the furniture itself, preferably stationary or immovable, can interact with each other and thus support the closing of the lamellae forward when folding the louver door, so that all lamellae of the louver door lie in one plane , In this simple way can be dispensed with a complicated deflection mechanism.

It is preferably provided that the first and the second magnet are poled and arranged so that in the closed position or shortly before reaching the closed position of the louver door of the first magnet and the second magnet repulsively interact with each other. This ensures that a folding of the last lamella is achieved by the repulsive effect of the magnet. It is also conceivable to place the second magnet on the furniture so that the folding of the lamella takes place by magnetic attraction.

According to an advantageous embodiment of the invention can also be provided that the second magnet and / or a third magnet is arranged so that it is polarized when moving the blind mat in the opening direction so that the second and / or the third magnet attracts the first magnet , In this way, the opening process and the deflection of the leading blade in the radius of the deflection can be supported.

Preferably, the first magnet is accommodated in the leading blade. In this way, the mechanism can not be viewed from the outside and the folding process of the blade takes place without recognizable mechanics.

The guides, in which the louver door is guided, can be formed continuously in the deflection area, so that the louver door does not derail from the guide when guided through the radius. Thus, the leading blade is still folded according to the invention by means of the magnetic effect, it is preferably provided that the leading blade is formed shorter in its longitudinal direction perpendicular to the opening direction relative to the other lamellae at the end faces facing towards the guides. Thus, a free flaps is possible while the remaining slats remain in the guide.

In particular, for the case just described but also generally according to a preferred embodiment of the present invention, a Umlenkhilfsanschlag be provided on the body in the deflection. This is in particular designed so that the leading blade runs when opening the louver door on the Umlenkhilfsanschlag and angling the leading blade from its position substantially parallel to the opening surface of the opening to the interior of the furniture.

The Umlenkhilfsanschlag may have an oblique or curved deflection. In the closed position of the louver door, the deflection surface preferably forms an angle to the plane of the front side of the leading lamella pointing to the outside. In this way, the deflection is facilitated because the angled deflection surface forms a guide for the leading blade.

According to a further embodiment it can be provided that at least the second and an optionally present third magnet are attached to a magnet holder, which has a rotary portion or a displacement portion and, in particular designed as a shaft, pivot bearing or sliding bearing, with respect to the Rotary section is rotatable about a rotation axis or the displacement section is displaceably mounted along a displacement direction.

In this way, a fine adjustment of the position of the magnets can be made and so the folding function of the last slat can be optimized. For this purpose, it can also be provided that the magnet holder has a fixing element, wherein the rotary section relative to the rotary bearing or the displacement section relative to the sliding bearing by means of the fixing element in a desired rotational position is fixed. With the fixing element, the rotational position of the rotary section or the displacement position of the displacement section is locked after the fine adjustment in the desired rotational position or displacement position. For this purpose, the fixing element may preferably be formed as a fixing screw, which is screwed into the holder, preferably radially, and locks the rotary member to the rotary bearing.

Preferably, it is further provided that at least the second and an optionally present third magnet is immovably connected to the furniture part. It is particularly advantageous that at least the second and an optionally present third magnet is connected via a magnetic holder with the furniture part. In terms of installation, this can for example be done so that the magnet holder is fixedly connected to an intermediate floor. Between this intermediate floor and the wall of the furniture body then the slatted door when opening into the body of the furniture inside pushed. The magnet holder is preferably located on the side of the intermediate bottom facing the louvered door.

The furniture 10 according to the invention has, as in FIGS. 1, 2 and 4A shown, a furniture body, which is bounded by two side walls 11, 12. On the side walls 11, 12 guides 13, 14 are mounted, in which a slatted door 20 is slidably guided to one between the side walls 11, 12 and the guides 13, 14 opening of the furniture to open or close. For this purpose, the louver door 20 is displaceably guided between an open position and a closed position. The louver door 20, which is preferably designed as a Venetian blind mat, has a plurality of fins 21, 22 which are hinged together. For engaging a user, a handle 30 may be attached to the louver door 20. In the closed position of the louver door 20 shown in FIG. 1, the outer sides of the lamellae 21, 22 are in a plane Y, Z, where Z in the example shown is the main extension direction of the guides 13, 14 and the vertical direction of the cabinet formed here by way of example Furniture referred and Y denotes the transverse direction in which the main extension direction of the slats 21, 22 is located. The joint axes of the hinged together lamellae 21, 22 also extend parallel to the transverse direction Y. Y (see. FIG. 2 ) denotes the depth direction of the furniture 10, perpendicular to the transverse direction Y and perpendicular to the vertical direction Z.

At the upper edge of the furniture 10 is still a cover 15 is provided. The guides 13, 14 are, as shown in Figure 4A, U- or C-profiles, which are attached to the forward facing narrow side of the side walls 11, 12 preferably via harpoon web or the like, and the louver door 20 with its lamellae 21 with two legs , 131, 132 enclose and guide.

In the Figures 3 and 4A is a sectional view through the furniture shown. A denotes the outside of the furniture 10, I the interior. One recognizes an upper body floor 16, an intermediate floor 17, the guide 13, in which the slatted door 20 is guided. Furthermore, the individual slats 21, 22 of the slatted door 20 are shown, which are connected to each other via joints 24, 25. The joints are formed here by hinges, wherein the lamellae 21, 22 on one side of a receptacle 25 and on the other side a pivot pin or pin 24 which is received in the receptacle 25 of the respective adjacent lamella 21. The guide, which initially runs in the direction Z, continues in a deflection region through a curved guide section 19, which in the example shown transfers the opened flap door 20 into a further guide section 18 (not necessarily running in the horizontal direction X). In this way, the louver door 20 is displaced into the furniture 10 during opening and runs between the carcass floor 16 and the intermediate bottom 17 through to an end position. Usually, the louver door 20 runs behind a (not shown here) inner rear wall, so that it is not visible when looking into the interior I of the furniture 10.

In the deflection region-this is the region of the furniture 10 in which the louver door 20 is guided by the radius of the guide section 19, that is to say the area around the section 19 -a magnet 41 is arranged, which preferably is furniture-mounted in or on one of the intermediate floor 17 mounted or mounted magnetic holder 40 is arranged. Further is arranged in the opening direction in front of leading blade 22 (also called "last lamella") a magnet 23. A magnet 23 is therefore preferably lamellentürfest and thus displaced, the other 41 is möbelfest and thus provided immovable.

If now the slat door 20 with its last slat from the open position (indicated by the position of the last slat according to Pos. 22 ') in the closed position (in FIG. 3 The last lamella 22, which has the magnet 23, passes through the radius 19 and enters the interaction region of the magnet 41. The polarities of the magnets 23 and 41 are selected such that repulsion occurs in this region. indicated by the arrow P1. As a result of the fact that the poles S of the magent 41 and S of the magent 23 interact here with each other, repulsion occurs and the last slat 22 is folded forward in the direction of the outer side A when the slatted door 20 is closed into the vertical end position. The magnet 41 is slightly oblique to the vertical direction Z - obliquely in the example shown - in order to optimize the repulsion P1 at the apex of the radius 19.

If the slatted door is opened, the last slat 22 is pushed into the position indicated by 22 '. It is first processed against the repulsion P1. In order to overcome the repulsion P1, a Umlenkhilfsanschlag 50 is provided, the coming out of the closed position of the first blade 22 against the repulsion and deflects in the radius 19. For this purpose, the Umlenkhilfsanschlag 50 preferred an inclined surface which is formed at an acute angle from the horizontal and sloping towards the front A. Runs the last blade 22 on this surface 50, it is folded inward and can be guided by the radius 19. If the lamella reaches the vertex of the radius 19 or even the position as at 22 ', the repulsive interaction with the magnet 41 decreases and the magnet 23 enters the attractive interaction region by the pole S of the pole N of the magnet 41 or a further inside the magnet holder 40 arranged additional magnet 42 is attracted (arrow P2). The last slat 22 thus flips over to the intermediate bottom 17 and is pushed with the remaining slatted door into the open position.

The in the Figures 5A and 5B The embodiment shown above differs from the previously described embodiment only in that the second and / or third magnet 41, 42 could be mounted on a magnetic holder, which is itself adjustable. In this respect, reference is made in full to the above remarks and only the differences are discussed.

The guide 18 can, as shown here, be part of a cassette insert 60 with which the slatted door or blind 20 is inserted into the body of the piece of furniture (10). The magnet holder 40 is movable in the example shown, in particular about a rotational axis A perpendicular to the directions X and Z (perpendicular to the plane) rotatably formed. This allows the relative position of the magnets 41 and 42 in the way of Fine adjustment adjusted to achieve an optimal rattle result for the slat 22 and to optimize the magnetic interaction.

The holder 40 may be a shaft, in particular a support shaft of the cassette insert 60. Im in FIG. 5B In the example shown, the holder has a ring or rotary portion 44 rotatably mounted about a shaft 45 (as indicated by the arrow P3), on or in which the magnets 41, 42 (if present) are held. The rotary portion 44 is preferably fixed in any rotational position with respect to the shaft 45. For this purpose, a fixing element 43 is used, which is a fixing screw in the example shown, which passes through the rotary section radially and is fixable in the shaft 45, so that by fixing a rotation of the rotary portion 44 is no longer possible.

Incidentally, the magnetic interaction can also be designed so that the folding through the magnetic attraction and the folding back or deflecting by magnetic repulsion is achieved. To do this, the unmoored magnet 41, 42 would have to be e.g. be attached to the cheek 16 of the body.

In any case, the folding of the last lamella 22 is achieved in a simple manner by said magnetic interaction, without complicated fittings or multiple guides are required. Again, the end panel 15 can be omitted or at least designed much narrower than with louver doors without Vorlappmechanismus.
