• a first drive device, by means of which the guide device, starting from the second guide rail, can be moved at least in sections in the direction of the first guide rail.

The invention also relates to an arrangement with two hinged furniture parts, in particular door leaves of a folding door, and with a guide system of the type to be described. The invention also relates to a piece of furniture with such an arrangement or with such a guide system.

In the WO 2016/081961 A1 and in the WO 2016/081963 A1 mechanical drive devices for folding sliding doors are shown, the folding sliding door starting from a side shaft in which the door leaves assume a folded position to one another, into an outside of the Well located position is movable, in which the door leaves can be spread apart relative to each other. The disadvantage of this is that the door leaves are in an undefined intermediate position after they have been spread open.

The object of the present invention is to provide a guidance system of the type mentioned at the beginning with a more convenient operating option.

According to the invention, this is achieved by the features of claim 1. Further advantageous embodiments of the invention are specified in the dependent claims.

According to the invention, it is provided that the guide system has at least one second drive device, by means of which the guide device can be moved, starting from the first guide rail, into a position in which the first fitting part and the second fitting part are aligned with one another in such a way that the Furniture parts connected to the fitting parts are aligned essentially coplanar with one another.

The proposed guide system makes it possible to transfer the furniture parts in the assembled state from a first position in which the furniture parts are aligned parallel to one another to a second position in which the furniture parts are aligned essentially coplanar with one another. In the assembled state, the furniture parts can therefore be moved into a defined end position by the second drive device, namely into that in which the furniture parts are aligned essentially coplanar with one another.

It is preferably provided that the drive devices provided for moving the furniture parts function exclusively mechanically, ie without an electrical drive and without further electrical components.

Fig. 1a shows a possible application of a guide system 2 for guiding a first furniture part 3a, preferably in the form of a first door leaf of a folding door, the first furniture part 3a being articulated in the assembled position via a vertical axis 5a to a second furniture part 3b in the form of a second door leaf. Optionally, at least two further furniture parts 4a, 4b can also be provided, which are also pivotably connected to one another via a vertically extending axis 5b. The furniture parts 3a, 3b and 4a, 4b are movably supported by the guide system 2 relative to a furniture body 36 of a piece of furniture 37 which is stationary during operation. The guide system 2 can be used, for example, as a room dividing system, so that in a living room a like in Fig. 1a Furniture body 6 shown in the form of a kitchen block, an office niche, a storage room, a shelf, etc. through the furniture parts 3a, 3b; 4a, 4b can be completely covered and thus optically separated from the rest of the living space. The Guide system 2 can also be used for cabinet systems such as a walk-in cabinet. The mode of operation is explained below with reference to furniture parts 3a and 3b, the same statements being valid for furniture parts 4a, 4b.

The furniture parts 3a, 3b are moved by the guide system 2 between a first position in which the furniture parts 3a, 3b are aligned essentially parallel to one another ( Fig. 1a ) and a second position in which the furniture parts 3a, 3b are aligned essentially coplanar to one another, movably supported. In the first position, the furniture body 6 is freely accessible to a person, the two furniture parts 3a, 3b being able to be accommodated in a space-saving manner in an insertion shaft 7a present laterally next to the side wall 8a. The two other furniture parts 4a, 4b can also be received in a parallel position to one another in a further lateral insertion shaft 7b.

The guide system 2 comprises a first guide rail 9 with a longitudinal direction (L) for guiding the furniture parts 3a, 3b. This guide rail 9 can, for example, be attached to a room ceiling, a room wall or also to the fixed furniture body 36. The guide system 2 further comprises at least one (not visible here) second guide rail 13a, which in the assembled state runs transversely to the longitudinal direction (L) of the first guide rail 9 and through which the furniture parts 3a, 3b in one direction (Z) or in one of the directions (Z) are movable in the opposite direction. Furthermore, a guide device 10 which can be connected to the first furniture part 3a and is movable relative to the first and second guide rails 9, 13a ( Fig. 2a ) intended. The other two furniture parts 4a, 4b are movably supported via a separate guide device 10a. Based on the in Fig. 1a The position shown, in which the furniture parts 3a, 3b assume a parallel position to one another and are accommodated in the lateral insertion slot 7a, are the furniture parts 3a, 3b in an overpressure position by exerting mechanical force in the direction (Z) movable, whereby a (not visible here) first drive device 12 can be triggered. After the first drive device 12 has been triggered, the furniture parts 3 a, 3 b are moved into the positions shown in FIG. 1 by the first drive device 12 Figure 1b The position shown is movable, in which the furniture parts 3a, 3b are located outside of the insertion shaft 7a and continue to assume a substantially parallel position to one another. Based on the in Figure 1b The position shown, the two furniture parts 3a, 3b - if necessary - by a spreading device 46 ( Figure 14a ) are moved starting from the parallel position to one another into a spread position to one another, so that the furniture parts 3a, 3b assume an angular position to one another.

Fig. 2a shows one to Figure 1b continued movement of the furniture parts 3a, 3b to one another, the other two furniture parts 4a, 4b have already been moved into a position in which the furniture parts 4a, 4b are aligned coplanar to one another and thereby cover the furniture body 6. The guide device 10 has at least one first fitting part 41 for fastening the first furniture part 3a. The guide system 2 comprises a carrier 11 ( Figure 3b ), which is movably mounted transversely to the longitudinal direction (L) of the first guide rail 9 and which is connected to at least one second fitting part 18 for fastening the second furniture part 3b. In the exemplary embodiment shown, the carrier 11 is connected to a vertically extending column 14 which, together with the carrier 11, is movably mounted in the direction (Z) extending transversely to the longitudinal direction (L) of the first guide rail 9. In this case, two or more fitting parts 18 for movably mounting the second furniture part 3b can be arranged on the vertical column 14 and are spaced apart from one another in the vertical direction of the column 14. The guide device 10 connected to the first furniture part 3a can be transferred back and forth between the first and second guide rails 9, 13a in an intersection area 45 - seen in the assembled position in a plan view of the first and second guide rails 9, 13a. A second drive device 53 ( Figure 15a ) is the guide device 10 starting from the first guide rail 9 in a Movable position in which the first fitting part 41 of the guide device 10 and the second fitting part 18 are aligned with one another in such a way that the furniture parts 3a, 3b connected to the fitting parts 41, 18 in the assembled state are aligned essentially coplanar with one another, as shown in FIG Figure 2b is shown.

Fig. 3a shows the furniture 37 in a perspective view, the first guide rail 9 and at least one second guide rail 13a for guiding the furniture parts 3a, 3b can be seen. In the embodiment shown, two second guide rails 13a, 13b are provided, which are spaced from one another in the height direction. The carrier 11 is - together with the column 14 connected to it - movable in direction (Z) and in a direction opposite to (Z). The first guide rail 9 and the second guide rail 13a can be designed as separate components, which in the assembled state can either assume the same or a different height position. As an alternative to this, it is possible for the first guide rail 9 and the second guide rail 13a to be formed in one piece with one another and to be connected to one another via an arcuate section. The intersection area 45 results in a plan view through that area in which the guide rails 9, 13a or imaginary extensions of the guide rails 9, 13a intersect with one another. The guide system 2 comprises a first drive device 12, by means of which the guide device 10 can be drawn in at least in sections starting from the second guide rail 13a in the direction of the first guide rail 9 and / or starting from the intersection area 45 at least in sections along the second guide rail 13a.

Figure 3b shows the in Fig. 3a circled area in an enlarged view. The first furniture part 3a is connected to a guide device 10, by means of which the furniture parts 3a, 3b are movably supported along the first and second guide rails 9, 13a. One can see one from the guide rail 9 separate carrier 11 in the form of a movable carriage, which in a transfer position in the longitudinal direction (L) connects to the first guide rail 9 in such a way that the guide device 10 connected to the first furniture part 3a can be transferred back and forth between the first guide rail 9 and the carrier 11 is. The guide device 10 can have at least one first roller 15a with a vertical axis of rotation for absorbing lateral forces and at least one second roller 15b with a horizontal axis of rotation for absorbing vertical forces, the rollers 15a, 15b along a profile section 9a running in the longitudinal direction (L) Guide rail 9 are movably mounted. The carrier 11 also has a profile section 11a with a cross-section which corresponds to a shape and size of the profile section 9a in cross section, so that the guide device 10 can be transferred back and forth between the first guide rail 9 and the carrier 11. The carrier 11 can, for example, have at least two guide channels 16a, 16b running in the longitudinal direction (L) for guiding the rollers 15a, 15b.

The guide device 10, which is displaceable along the first guide rail 9, is still on the first guide rail 9 in the transfer position of the carrier 11 shown. The carrier 11 can be releasably locked in the transfer position with the first guide rail 9, this locking being achieved by retracting or opening the guide device 10 is releasable in or on the carrier 11. After unlocking, the carrier 11 - together with the guide device 10 and the two furniture parts 3a, 3b - can be moved in a horizontal direction (Z) running transversely, preferably at right angles, to the longitudinal direction (L) of the first guide rail 9. The carrier 11 is connected to the vertically running column 14, which can be driven by the first drive device 12 at least in sections in the direction (Z) and / or in a direction running counter to the direction (Z). The column 14 is movably supported relative to second guide rails 13a and 13b, which in the assembled position are spaced apart from the first guide rail 9 in the vertical direction.

Figure 4a shows the furniture parts 3a and 3b after this starting from Fig. 3a have been pivoted to one another about the vertical axis 5a and now assume an essentially parallel position to one another. Figure 4b shows the in Figure 4a circled area in an enlarged view, wherein the guide device 10 is located on the carrier 11 in the transfer position. It can be provided here that a length of the carrier 11 measured in the longitudinal direction (L) is greater than a width of the guide device 10 measured in the longitudinal direction (L). The profile section 9a of the guide rail 9 and the profile section 11a of the carrier 11 are preferably identical in cross-section and aligned with one another in the transfer position, so that the rollers 15a, 15b of the guide device 10 between the first guide rail 9 and the carrier 11 without a disturbing abutting edge and are movable forward. Based on the in Figure 4b The position shown, the carrier 11 together with the guide device 10 (and thus the furniture parts 3a, 3b) can be driven at least in sections in the direction (Z) by the force of the first drive device 12.

Figure 5a shows a side view of the carrier 11 in the transfer position, which is connected to the vertically extending column 14. The column 14 can be moved - together with the carrier 11 - for example via support rollers 17a, 17b along second guide rails 13a, 13b fastened to the side wall 8a in direction (Z). At least one fitting part 18 for movably mounting the furniture part 3b is arranged on the column 14, whereby it is preferably provided that the fitting part 18 is part of the second drive device 53 ( Figures 15a, 15b ), through which the furniture parts 3a, 3b, starting from a position parallel to one another, can be moved into a coplanar position to one another. A bearing part 24 is arranged on the column 14, on which at least one, preferably several, energy stores 21 of the first drive device 12 for pulling in the furniture parts 3a, 3b in the direction (Z) are anchored. The energy storage devices 21 are each as shown in the figure Tension springs are formed which act on a driver 20 which is pivotably mounted on the column 14 about an axis of rotation 19. A pressure roller 22 is rotatably mounted on the driver 20, which can be pressed by the force of the energy accumulator 21 against a concave control cam 23 of the first drive device 12 and which can be moved along this control cam 23 when the column 14 moves in direction (Z). The control cam 23 comprises a pull-in section 23a for partially pulling in the carrier 11 in the direction (Z) and a tensioning section 23b adjoining the pull-in section 23a for charging the energy storage devices 21 Figure 5a the energy storage devices 21 are in a tensioned state, so that the column 14 (and thus the carrier 11) after the carrier 11 has been unlocked from the first guide rail 9 by the force of the relaxing energy storage mechanisms 21 along the intake section 23a down to the deepest area of the Control cam 23 is retractable. As a result, the furniture parts 3a, 3b are also partially drawn into the insertion slot 7a, as a result of which they are favorably pre-positioned for continued movement in the insertion slot 7a in direction (Z). By then manually exerting pressure on the furniture parts 3a, 3b, which are aligned parallel to one another, in the area of the axis of rotation 5a, the column 14 (and thus the pressure roller 22) is moved further in direction (Z) along the clamping section 23b of the control cam 23, the energy storage device 21 being reloaded will. When the pressure roller 22 of the driver 20 comes to the end region 23c of the control cam 23, the energy storage devices 21 are fully charged, so that the furniture parts 3a, 3b through the energy storage device 21 during an extension movement in the opposite direction (Z) starting from a slot 7a completely retracted position are at least partially movable against the direction (Z). In addition, a movably mounted switch 25, preferably tiltable about an axis of rotation 25a, is provided with an adjusting contour 25c, the pressure roller 22 being displaceable, starting from the said inserted position, when moving against the direction (Z) along the adjusting contour 25c of the switch 25. It is thereby achieved that the pressure roller 22 pretensioned by the energy storage device 21 does not interfere with a movement against the direction (Z) The draw-in section 23a of the control cam 23 must be overcome, so that the draw-in section 23a can be bypassed by the pressure roller 22 and the force of the energy accumulator 21 is maintained over a longer distance. Figure 5b shows the in Figure 5a circled area in an enlarged view.

Figure 6a shows a continued movement of the column 14 (and thus of the carrier 11) in direction (Z). Due to the decreasing distance of the control cam 23 in the intake section 23a ( Fig. 3a ) In relation to the bearing part 24, the energy storage devices 21 are relaxed and pull the column 14 or the carrier 11 in the direction (Z). Figure 6b shows the in Figure 6a circled area in an enlarged view. When the pressure roller 22 has reached the deepest area of the control cam 23, the pressure roller 22 is moved onto the tensioning section 23b of the control cam 23 by manual exertion of force on the movable furniture parts 3a, 3b, so that the energy storage devices 21 can be recharged. The switch 25, which can be tilted about the axis of rotation 25a, is raised by the pressure roller 22 ( Figure 6c ), so that the pressure roller 22 moves unhindered past the switch 25 during a movement in direction (Z) and can be moved further along the tensioning section 23b. The eccentric articulation of the switch 25 around the axis of rotation 25a forms a two-armed lever with lever arms of different lengths, so that the switch 25 with the longer lever arm, preferably exclusively loaded by gravity, rests loosely on the clamping section 23b of the control cam 23. If appropriate, the switch 25 can also be pressed against the control cam 23 by a spring element. Fig. 6d shows the in Figure 6c circled area in an enlarged view.

Figure 7a shows the position of the column 14 shortly before reaching the end position completely pushed into the insertion shaft 7a. The pressure roller 22 was moved along the tensioning section 23b of the control cam 23 and is located just before the horizontally extending end region 23c of the control cam 23, so that the column 14 is accelerated neither in direction (Z) nor against direction (Z). The energy storage devices 21 are complete charged. A housing 29 is arranged on the column 14, in which a damping device 27 for damping a closing movement of the column 14 or of the carrier 11 is arranged. In the exemplary embodiment shown, the damping device 27 comprises two, preferably hydraulic, linear dampers connected in parallel, each with a piston-cylinder unit. Towards the end of the closing movement of the column 14, these linear dampers strike a stationary stop 26, whereby the plungers of the linear dampers are pressed in and the movement of the column 14 can therefore be braked. In addition, two ejector devices 28, each with a lockable energy accumulator, are arranged in the housing 29, the two plungers of the ejector devices 28 interacting with the stop 26 during the closing movement of the column 14 so that the energy accumulators of the ejector devices 28 can be charged and locked in a charged state. Figure 7b shows the in Figure 7a circled area in an enlarged view.

Figure 7c shows the end position of the column 14, the last closing movement of the column 14 being braked by the damping device 27 and the lockable energy storage devices of the ejecting devices 28 being charged. By overpressing the column 14 starting from its closed position into an overpressing position behind the closed position, the ejector devices 28 can be moved into an unlocking position, whereupon the column 14 is again opposite to the direction (Z.) by the force of the ejector devices 28 and then by the force of the charged energy storage device 21 ) is drivable. Figure 7d shows the in Figure 7c circled area in an enlarged view.

Figure 8a shows a position of the column 14 after it has been ejected by the ejector devices 28 against the direction (Z). The pressure roller 22 is in a position approaching the switch 25, the pressure roller 22 being moved against the direction (Z) no longer along the feed section 23a, but along the adjusting contour 25c arranged or formed on the switch 25. To this In this way, a uniform ejection process of the column 14 or of the furniture parts 3a, 3b is brought about without substantial fluctuations in the force of the energy storage device 21, the force of the energy storage device 21 being maintained over a longer distance. Figure 8b shows the in Figure 8a circled area in an enlarged view, the pressure roller 22 approaching the adjusting contour 25c of the switch 25 when the column 14 moves counter to the direction (Z) without the pressure roller 22 having to be moved along the wave trough of the feed section 23a.

Figure 8c shows a continued movement of the column 14 counter to the direction (Z), wherein the pressure roller 22 was moved along the adjusting contour 25c of the switch 25 and the switch 25 was pivoted about the axis of rotation 25a in the counterclockwise direction. As a result of this pivoting movement of the switch 25 about the axis of rotation 25a, the pressure roller 22 is returned to the starting area of the clamping section 23a. After the pressure roller 22 has left the adjusting contour 25c of the switch 25, the switch 25 tilts about the axis of rotation 25a back into the starting position, that is, into the position in which the longer lever arm of the switch 25 is again on the control cam 23 due to its higher weight is applied.

Figures 9a and 9b show a possible embodiment of a locking device 30, by means of which the carrier 11 can be locked in the transfer position or a parking position with the first guide rail 9 and which can be unlocked by moving the guide device 10 into or onto the carrier 11. The first furniture part 3a is connected to the guide device 10, which can be moved in the longitudinal direction (L) along the first guide rail 9. A sliding piece 33 is connected in a movement-coupled manner to the guide device 10, so that when the guide device 10 moves along the first guide rail 9, the sliding piece 33 also moves along with it. The sliding piece 33 has a projection 33a which, when moving into or onto the carrier 11, interacts with a counter-stop 35a of a coupling lever 35 ( Figure 9b ). The Coupling lever 35 is rotatably mounted about an axis of rotation 31, a latching element 35c being movable by coupling lever 35 which, in the locking position, engages in a corresponding recess 34 of first guide rail 9 and thereby locks carrier 11 relative to first guide rail 9. It can be provided that the coupling lever 35 is formed in one piece together with the latching element 35c. The coupling lever 35 can be pretensioned in the direction of the locking position by a spring (not shown) so that the carrier 11 can be automatically locked again with the guide rail 9 by the force of this spring when it moves against the direction (Z) and the guide device 10 starting from the carrier 11 can be transferred back to the guide rail 9 again.

Figures 10a and 10b show a continued movement of the sliding piece 33, which is motion-coupled to the guide device 10, in the longitudinal direction (L), the projection 33a of the sliding piece 33 cooperating with the counter-stop 35a of the coupling lever 35 and thus pivoting the coupling lever 35 about the axis of rotation 31, so that the locking element 35c out of the Recess 34 of the guide rail 9 is moved out and thereby the carrier 11 is released relative to the guide rail 9 for a movement in direction (Z).

The second drive device 43 comprises at least one actuating arm 67 connected to the second fitting part 18, a spring device 59 for applying force to the at least one actuating arm 67, a control cam 66 and a roller 61 loaded by the spring device 59, the roller 61 when the at least one moves Actuating arm 67 is movably mounted along the control cam 66. Furthermore, the second drive device 53 comprises a stop part 54, which is to be fastened to the vertically extending column 14, for example. The stop part 54 is constructed in two parts here and comprises a first part 54a for fastening to the column 14 and a second part 54b, the position of the second part 54b relative to the first part 54a being adjustable by rotating an adjusting wheel 68. The second part 54b is connected via an axis 64 to an intermediate piece 63 on which the control cam 66 is arranged or formed. The intermediate piece 63 is connected via a further axis 65 to a housing part 60 on which the roller 61 is rotatably mounted about an axis 62 and which can be pressed against the control cam 66 by the force of the spring device 59. The housing part 60 is designed to at least partially accommodate the spring device 59 and is mounted displaceably relative to the actuating arm 67, which is hingedly connected via the axis 55 to the fitting part 18 to be attached to the second furniture part 3b. The force of the spring device 59 exerted on the second furniture part 3a can be adjusted by an adjusting device 56 with an adjusting screw 57, whereby a stop element 58 can be adjusted along a threaded section arranged on the adjusting screw 57 by turning the adjusting screw 57 by means of a tool. The spring device 59, designed as a compression spring, is supported with a first end region on this stop element 58, which through Rotation of the adjusting screw 57 can be created along the threaded section of the adjusting screw 57 and thereby biases the spring device 59 differently. The second end of the spring device 59 presses against the roller 61, which can be moved along the control cam 66 by a movement of the actuating arm 67.

Fig.15b shows the second drive device 53 according to FIG Figure 15a in a cross section, the roller 61 being releasably locked with a first locking section 66a of the control cam 66, so that the two furniture parts 3a, 3b are held in a coplanar position to one another with a predetermined force in the assembled state. The first locking section 66a of the control cam 66 is trough-shaped here for receiving the roller 61, the roller 61 being moved out of the trough-shaped locking section 66a by a movement of the fitting part 18 and after overcoming a holding force and can be moved further along the control cam 66.

Figure 16a shows a cross section of the second drive device 53 according to FIG Figures 15a and 15b , the fitting part 18 being positioned such that the two furniture parts 3a, 3b are aligned parallel to one another in the assembled state and can be moved into and out of the lateral insertion slot 7a. The roller 61 loaded by the spring device 59 is releasably locked with a second trough-shaped locking section 66b of the control cam 66 so that the two furniture parts 3a, 3b are held in a parallel position to one another with a predetermined force in the assembled state. After moving out of the lateral insertion shaft 7a, the furniture parts 3a, 3b can, for example, by means of the in Figure 14a Spreading device 46 shown are spread open, the roller 61 moving out of the second locking section 66b and - as shown in FIG Figure 16b is shown - can move further along the control curve 66, the furniture parts 3a, 3b moving starting from the mutually parallel position in the direction of the coplanar position.
