Description

The invention relates to an arrangement for moving a movable furniture part relative to a furniture body, with a first movement device and a second movement device spaced apart therefrom, the two movement devices being connectable to the movable furniture part and to the furniture body, the arrangement having a synchronization device via which the Both movement devices are coupled or can be coupled to one another, and the arrangement has at least one energy store to support the movement of the movable furniture part and / or to at least partially compensate for a weight of the movable furniture part. The invention further relates to a piece of furniture with a furniture body and at least one furniture part that is movable relative to the furniture body.

Such an arrangement for moving flaps which can be pivoted about a horizontal axis is known, for example, from EP 1 875 026 A1. The two movement devices are often each equipped with energy stores in order to support the movement of the movable furniture part and / or to at least partially compensate for the weight of the movable furniture part.

The disadvantage here is that the energy stores are integrated in the movement devices. However, this also means that in the case of differently designed movable furniture parts, different movement devices have to be provided, since the energy stores can usually only be tuned, if at all, within a limited range. It is not possible to replace the lift mechanism. Rather, the entire movement devices have to be exchanged, which is connected on the one hand with considerable costs and on the other hand with a considerable assembly effort, since the connections of the movement devices to the movable furniture part and to the furniture body must be removed.

Another disadvantage is that the two movement devices have a space-occupying design due to the integrated energy store.

/ 27

The object of the present invention is to provide an arrangement which is improved compared to the prior art and which is characterized in particular by easier interchangeability of the at least one energy store and a more compact design of the two movement devices, or an item of furniture improved with respect to the prior art Specify order.

This object is achieved by the features of independent claims 1 and

10th

It is therefore provided in the arrangement according to the invention that the synchronization device has at least one device which, when the movable furniture part is moved relative to the movable furniture part and / or to the furniture body, has at least one energy store between the at least one movable device of the synchronization device and at least one a bearing point that is stationary relative to the at least one movable device of the synchronization device is effective.

As a result, it is possible to dimension the power storage devices provided in the two movement devices according to the prior art to be significantly smaller or even to save them entirely. This allows the two movement devices to be made more compact. Furthermore, the synchronization device, which is generally arranged between the two movement devices, can be exchanged more easily than the movement devices. Rather, the movement devices can remain connected to the movable furniture part and the furniture body. By exchanging the synchronization device, the at least one energy store can thus be exchanged more easily, so that, compared to the prior art, a simpler adaptation to the design of the movable furniture part, for example the weight of the movable furniture part, can be carried out.

According to a preferred embodiment, it is provided that the at least one energy accumulator comprises at least one torsion spring with a first end and a second end, the first end of the torsion spring being motion-coupled to the at least one movable device of the synchronization device and the second end of the Torsion spring is connected to the at least one stationary bearing point.

The training as a torsion spring has the particular advantage that torsion springs generally have a very flat spring characteristic, so that force or energy can be deposited in the torsion spring without this being associated with considerable effort by the user of the movable furniture part. In other words, the torsion spring can be loaded without this significantly hindering the movement of the movable furniture part.

A torsion spring is generally understood to be a spring in the cross sections of which, when rotated about a longitudinal axis, torsional stresses arise which are in equilibrium with a torsional moment applied from the outside. For example, the spring may have a cylindrical or rectangular cross section. A coil spring is also a torsion spring. It is a helically wound rod which, just like a straight torsion spring, is elastically stressed over its entire length by a torsional moment.

A particularly advantageous embodiment of the invention consists in that the two movement devices have means for generating a torque when the movable furniture part moves relative to the furniture body and the at least one movable device of the synchronization device is designed as a synchronization rod which is rotatably mounted on the two movement devices and with them the means for generating a torque is motion-coupled. In this embodiment, force or energy can be deposited in the torsion spring in a particularly simple manner or can be retrieved from the torsion spring.

It can be provided that the means for generating a torque on at least one pivotably mounted lever, at least one gear and / 27 at least one rack, in which the at least one gear can engage, and / or at least one rope and at least one spindle which the at least one rope can be wound up and unwound.

It has proven to be advantageous that - if the at least one energy accumulator comprises at least one torsion spring - the at least one torsion spring is wound around the synchronization rod. Alternatively, it can also be provided that the synchronization rod is, for example, partially hollow and the at least one torsion spring is arranged at least partially in the cavity of the synchronization rod created in this way.

It makes sense that the synchronization rod is composed of at least two sections in the direction of its longitudinal extent, preferably with the at least two sections being releasably connectable. This is particularly advantageous in the case of arrangements for moving very large movable furniture parts, such as doors, since the arrangement can be packed in a space-saving manner for shipping.

An advantageous development of the invention is that the synchronization device has at least one transmission gear. In this way it is possible to change the ratio with which force or energy is deposited in or called up by the at least one torsion spring. For example, it is advisable to provide such a transmission mechanism in the case of a movable furniture part which is designed as a flap, since a flap generally travels a comparatively short distance between the closed position and the open position.

In the case of movable furniture parts with a high weight, such as doors, sliding doors or folding sliding doors, it has proven to be advantageous for reasons of stability that the arrangement comprises at least one carrier via which the two movement devices can be connected to the movable furniture part, preferably in which case the synchronization device is at least partially integrated into the at least one carrier.

/ 27

The two movement devices can be designed very differently depending on the design of the furniture part to be moved. Thus, it can be provided that the two movement devices, in particular in the case of a linearly movably mounted furniture part, have at least one guide rail or, in particular in the case of a pivotably mounted furniture part, an actuating arm.

As stated at the beginning, protection is also sought for a piece of furniture with a furniture body and at least one furniture part which can be moved relative to the furniture body, the furniture having at least one arrangement according to the invention, the two movement devices being connected to the at least one movable furniture part and to the furniture body, preferably wherein the movement devices are arranged on at least one side wall of the furniture body.

The at least one movable furniture part can be designed as a door, sliding door, folding sliding door, flap or drawer.

In particular in connection with furniture which comprises sliding doors or folding sliding doors, it is advisable that the furniture body has at least one, preferably laterally arranged, receiving shaft for receiving the at least one movable furniture part, preferably with the at least one receiving shaft having a clear width of 10 to 30 cm and / or a height of 100 to 250 cm and / or a depth of 60 to 100 cm.

Further details and advantages of the invention are explained in more detail below with reference to the description of the figures and with reference to the drawings. In it show:

Embodiment, the three partial views showing different positions of the movable furniture part in the form of a folding sliding door, an arrangement according to the invention according to a first preferred embodiment, wherein Fig. 2b shows a detailed view of section 58 of Fig. 2b, another detailed view of the arrangement according to the invention the first preferred embodiment in a changed position compared to FIGS. 2a and 2b, furniture according to the invention according to a second preferred embodiment or an arrangement according to the invention according to a second preferred embodiment, FIG. 4a a perspective view and FIG. 4b a front view shows, and a drawer with an arrangement according to the invention according to a third preferred embodiment.

Figure 1a shows a piece of furniture 40 with a furniture body 6 and two movable furniture parts 4, which are each designed as folding sliding doors.

The furniture body 6 has a receiving area 46 in which, for example, a kitchen, parts of a kitchen or clothes storage devices can be arranged. A baking oven with hot plates and a drawer cabinet arranged next to it can be seen in FIG. 1a and additional wall cabinets can be seen in FIG. 1b.

The furniture body 6 also has two receiving shafts 45, in which the two folding sliding doors 4 can be arranged. As in the case shown, the receiving shafts 45 can be formed, for example, by two side walls 43 and 47 arranged essentially parallel to one another with a spacing.

FIG. 1 a shows a position of the folding sliding doors 4 in which the folding sliding doors 4 are arranged almost completely in the receiving shafts 45.

/ 27

1 b shows a position of the folding sliding doors 4, in which the left folding sliding door 4 is arranged outside the associated receiving shaft 45, but still occupies a folded position, whereas the right folding sliding door 4 is already slightly bent. This means that the two door leaves, from which the folding sliding doors 4 are composed, are no longer arranged one on top of the other. A position of the folding sliding doors 4 is shown in FIG. 1c, in which the two folding sliding doors 4 are completely unfolded and completely cover the receiving area 46.

In the case of the furniture 40 shown in FIGS. 1a to 1c, two arrangements 1 according to the invention according to a first preferred exemplary embodiment are used to move the folding sliding doors 4 relative to the furniture body 6. One of these arrangements 1 is shown in FIGS. 2a, 2b and 3, approximately from a viewing direction which is indicated by the arrow 59 in FIG. 1b.

The arrangement 1 comprises a first movement device 8 and a second movement device 11 spaced therefrom. The two movement devices 8 and 11 each comprise a guide rail 35 and 36, respectively, which are arranged on a side wall 43 of the furniture body 6. That is, in this case the two movement devices 8 and 11 serve to move the folding sliding door 4 into or out of the receiving shaft 45. A further guide device 42 is arranged transversely thereto, which serves to fold the folding sliding door 4 together or apart in order to open or cover the receiving area 46. This guide device 42 is not part of the arrangement

1.

The arrangement 1 further comprises a synchronization device 14, via which the two movement devices 8 and 11 are coupled to one another. The synchronization device 14 comprises a device 25 in the form of a synchronization rod, this device 25 being movable when the folding sliding door 4 moves to the folding sliding door 4 to the furniture body 6. The synchronization rod 25 is in the direction 28 of its longitudinal extension from three / 27th

Pieces 29, 30 and 31 assembled, the three pieces 29, 30 and 31 being releasably connectable. For this purpose, connectors 48 are provided, which are each arranged between two sections 29, 30 and 31.

The arrangement further comprises a carrier 34, via which the two movement devices 8 and 11 are connected to the folding sliding door 4, the synchronization device 14 being integrated in the carrier 34. This enables a very compact structure to be achieved. The carrier 34 is also composed of several sections in the case shown.

It can be seen from the detailed view according to FIG. 2 b that the arrangement 1 furthermore has an energy store 17 for supporting the movement of the movable furniture part 4, the energy store 17 comprising a torsion spring. The torsion spring has a first end 18 and a second end 19, the first end 18 of the torsion spring being connected to the movable synchronization rod 25 in a motion-coupled manner. For this purpose, a sleeve 50 is provided, which is connected in a rotationally fixed manner to the synchronization rod and on which the end 18 of the torsion spring is fixed. The second end 19 of the torsion spring is fixed relative to the synchronization rod 25. Specifically, the second end 19 is fastened to the carrier 34 via a fastening device 49. The torsion spring is wound around the synchronization rod 25.

The movement device 8 further comprises means 20, 21 for generating a torque when the movable furniture part 4 moves relative to the furniture body 6. In the illustrated case, the means 20, 21 comprise a rope 20 and a spindle 21, on which the rope 20 is opened and closed can be developed. One end of the cable 20 is fastened to the guide rail 35 via a device 51. The synchronization rod 25 is rotatably mounted on the movement device 8 and connected to the spindle 21 in a motion-coupled manner.

Figure 2b also shows a guide carriage 52 which is slidably mounted on the guide rail 35. The folding sliding door 4 or the carrier 34 is attached to the guide carriage 52. FIG. 2b also shows that / 27

Arrangement 1 can also include further means for influencing the movement of the movable furniture part 4, such as a damping device 53. To visualize the damping device 53, the guide carriage 52, the cable 20 and the spindle 21, part of the guide rail 35 has been cut out in the drawing. In reality, the above-mentioned components of the arrangement 1 are covered by the guide rail 35 in this view.

FIG. 3 shows a position of the carrier 34 or the synchronization device relative to the guide rail 35 or a furniture body 6 that is changed compared to FIG. 2b. As can be seen from a comparison of the representations according to FIGS. 2b and 3, when the carrier 34 moves, along the guide rail 35, the rope 20 is wound onto the spindle 21 and unwound again. The position of the rope 20 remains essentially unchanged. By unwinding and winding up the rope 20 on the spindle 21, the spindle 21 and thus the synchronization rod 25 are set in rotation. The rotation is transmitted to the torsion spring via the end 18. Since at the same time the end 19 of the torsion spring is stationary, a torsional stress builds up in the torsion spring. In other words, force or energy is deposited in the torsion spring.

This loading of the energy store 17 can take place either when the movable furniture part 4 is pushed into the receiving shaft 45 or when the movable furniture part 4 is moved out of the receiving shaft 45. The force deposited in the energy store 17 is then available for the opposite movement and can support or even take over the movement of the movable furniture part 4.

FIGS. 4a and 4b show a second preferred exemplary embodiment of an arrangement 2 or a piece of furniture 41 with such an arrangement 2. The piece of furniture 41 comprises a furniture body 7 with two side walls 44. On these side walls 44, which are spaced apart from one another, are each a movement device 9 and 12 arranged. The movement devices 9 and 12 each comprise a housing 54 and an actuating arm 39 which is relative to the / 27th

Housing 54 is pivotally mounted. At the end of the actuating arm 39, a furniture flap can be attached via a device 55.

The two movement devices 9 and 12 are coupled to one another via a synchronization device 15. The synchronization device 15 comprises a device 26 in the form of a synchronization rod, the device 26 being movable relative to the flap and the furniture body 7 when the flap or the adjusting arms 39 are moved.

As in the first exemplary embodiment according to FIGS. 2a, 2b and 3, the arrangement 2 comprises an energy store 17 with a torsion spring. A first end 18 of the torsion spring is coupled to the movable device 26 in a motion-coupled manner. The second end 19 of the torsion spring is fixed in place relative to this movable device 26. The storage can take place, for example, on the housing 54 of the movement device or directly on the furniture body 7.

The principle of operation of the arrangement 2 is essentially the same as in the first exemplary embodiment. An essential difference is the design of the means for generating a torque. Specifically, in the present case, they are designed as a pivotably mounted lever 22, which is part of the actuating arm 39. The synchronization rod 26 can, for example, be connected or connectable to the lever 22 or the actuating arm 39 via an extension which is connected to the lever 22 in a manner fixed against relative rotation.

In the present case, it is advisable for the torsion spring to be loaded when the flap is folded down; H. when the flap moves from the open to the closed position. The energy stored in the torsion spring during this movement can then be used to balance the weight of the furniture flap and / or to support the opening, ie. H. can be used to support the movement of the furniture flap from the closed to the open position.

In the exemplary embodiment shown, the actuating arm 39 or the lever 22 moves in an angular range of approximately 120 °. In this case it makes sense to use the / 27

Synchronization rod 26 and the fixed end of the torsion spring to arrange a transmission gear.

FIG. 5 shows a third preferred exemplary embodiment of an arrangement 3 for moving a movable furniture part 5 in the form of a drawer. A first movement device 10 and a second movement device 13 spaced therefrom are arranged on the drawer bottom 57. The movement devices 10 and 13 each comprise a body rail 37 to be connected to a furniture body and a drawer rail 38 connected to the drawers 5, it being possible for further rails to be provided between these two guide rails.

The two movement devices 10 and 13 are coupled to one another via a synchronization device 16, the synchronization device 16 being configured essentially as in the first and second exemplary embodiments. The synchronization device 16 in turn comprises a movable device 27 in the form of a synchronization rod, the synchronization rod in this case being composed of two sections 32 and 33. A first end 18 of the torsion spring is coupled to the synchronization rod 27 in a motion-coupled manner. A second end 19 is fixed in position relative to the synchronization rod 27. This can be achieved, for example, by attachment to the drawer 5 or to a projection 56 which is arranged on the drawer 5.

An essential difference in this embodiment is the design of the means for generating a torque when the movable furniture part 5 moves relative to a furniture body. In this case, in the case of the two movement devices 10 and 13, these means each comprise a toothed wheel 23 and a toothed rack 24, in which the toothed wheel 23 can engage.

In this case, the synchronization device 16 fulfills a double function. On the one hand, this results in a lateral stabilization of the drawer 5, as described, for example, in the Austrian patent specification AT 509257. On the other hand, according to the invention, the synchronization device 16 comprises the at least one energy store 17. Force or energy which is stored in the course of moving the drawer 5 in or out can be stored in the opposite one

Direction of movement can be used to support the movement of the drawer 5.
