Description

• eine erste Führungsschiene zur Führung der Möbelteile,
• eine zweite Führungsschiene zur Führung der Möbelteile, wobei die zweite Führungsschiene in Montagelage relativ zur ersten Führungsschiene quer verläuft,
• eine mit einem der Möbelteile verbindbare und relativ zur ersten und zweiten Führungsschiene bewegbare Führungsvorrichtung, welche in einem - in Montagelage in einer Draufsicht auf die erste und zweite Führungsschiene gesehenen - Kreuzungsbereich zwischen der ersten und zweiten Führungsschiene hin und her transferierbar ist.

The present invention relates to a guide system for guiding a movably mounted first furniture part, in particular a first door leaf of a folding door, which is connected in an articulated manner to at least one second furniture part, in particular a second door leaf of a folding door, comprising:

• a first guide rail for guiding the furniture parts,
• a second guide rail for guiding the furniture parts, the second guide rail running transversely relative to the first guide rail in the assembled position,
• a guide device which can be connected to one of the furniture parts and is movable relative to the first and second guide rails and which can be transferred back and forth in an intersection area between the first and second guide rails - seen in the assembled position in a plan view of the first and second guide rails.

Furthermore, the invention 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 EP 0 433 726 B1 shows a rail arrangement for guiding cabinet doors which, in the assembled position, are articulated to one another via a vertically extending axis of rotation. Due to the rail arrangement, the cabinet doors are movably supported between a first position in which the cabinet doors are aligned coplanar with one another and a second position in which the cabinet doors are aligned parallel to one another, the cabinet doors being accommodated in a lateral slot in the second position . The rail assembly includes a first guide rail that runs parallel to the front of the cabinet and a second guide rail that is perpendicular to the first guide rail is arranged. In addition, a carrier is provided (reference number 5 in Fig. 1 ), on which a first cabinet door is hinged and which can be moved in the horizontal direction via guide rails parallel to an outer wall of the cabinet, so that the two cabinet doors can be pushed into the slot. A guide element is arranged on the second cabinet door (reference number 7), which is mounted so as to be movable along the first guide rail. The disadvantage of this construction is that the guide element collides with the U-shaped legs of the guide rails at the right-angled transition between the first and second guide rails, thus preventing the guide element from moving into the guide rails.

In the WO 2016/081963 A1 , in the WO 2016/081961 A1 and in the DE 297 10 854 U1 Guide systems are disclosed for hinged door leaves, wherein the door leaves in a folded position can be pushed into a laterally arranged cabinet compartment of the furniture body by manually exerting pressure on the door leaves. Depending on the size and weight of the door leaves, this requires a relatively high level of manual effort.

The object of the present invention is to provide a guide system of the type mentioned at the beginning while avoiding the above disadvantage.

This is achieved according to the invention by the features of claim 1. Further advantageous refinements of the invention are given in the dependent claims.

According to the invention, it is provided that the guide system has a drive device with a driver acted upon by at least one energy storage device and releasably couplable to the guide device, the driver being locked in a parking position and the driver entering the intersection area by the guide device can be unlocked so that the driver, together with the guide device coupled therewith, can be drawn in at least in sections along the second guide rail by the force of the at least one energy store.

The proposed guide system allows at least two furniture parts articulated to one another via an axis of rotation between a first position in which the furniture parts are aligned essentially coplanar to one another and a second position in which the furniture parts are folded together and assume an essentially parallel position to one another The furniture parts can be moved along the second guide rail at a transition from the first guide rail to the second guide rail by the drive device and, if appropriate, can be pulled into a lateral insertion slot of a piece of furniture at least in sections by the force of the drive device.

The drive device can be designed purely mechanically, i.e. without electrical drives or without other electrical components.

The general basic principle of the invention is based on the Figures 13a-13d explained, each showing a plan view of the guide system 2. The guide system 2 comprises a first guide rail 9 with a longitudinal direction (L) and a second guide rail 13a for guiding at least two furniture parts 3a and 3b, which in the assembled position are articulated to one another via a vertically running axis of rotation 5a. The second guide rail 13a runs transversely to the first guide rail 9, preferably essentially at right angles. A guide device 10 to be connected to the first furniture part 3a (for example a slide with several rollers) is mounted movably along the first guide rail 9 in the longitudinal direction (L). The furniture parts 3a, 3b take in Figure 13a a first position in which the furniture parts 3a, 3b are aligned essentially coplanar to one another. The Guide system 2 has a drive device 12 with a movably mounted driver 20 which can be detachably coupled to the guide device 10 and which is in a manner as shown in FIG Figure 13a parking position shown is biased by at least one energy storage device 21. The driver 20 is releasably locked in the parking position shown, in which the energy storage device 21 is loaded, so that a movement of the driver 20 in the direction transverse to the longitudinal direction (L) is prevented. This locking of the driver 20 can, for example, by a separate locking device 30 ( Figures 7a, 7b ) or even without the aid of a separate device, in particular through the geometric specification of a guide track, which, through the interaction with the energy storage device, brings about a self-locking locked parking position of the driver (e.g. by means of a curved or beveled section of the guide track, as in the EP 391 221 B1 shown).

Starting from Figure 13a the furniture parts 3a, 3b can be moved about the axis of rotation 5a in an angular position to one another, the guide device 10 moving in the longitudinal direction (L) of the first guide rail 9 ( Figure 13b ). The furniture parts 3a, 3b can then be moved into a second position in which the furniture parts 3a, 3b are aligned essentially parallel to one another ( Figure 13c ). The driver 20 can be unlocked by an entry of the guide device 10 in an intersection area 45 - seen in the assembled position in a plan view of the two guide rails 9, 13a - and can be coupled to the guide device 10, so that the driver 20 together with the guide device 10 coupled therewith through the Force of the discharging energy storage device 21 can be drawn in at least in sections along the second guide rail 13a in direction (Z) ( Figure 13d ). This indentation can be designed up to a predetermined end position of the furniture parts 3a, 3b or as a partial indentation. In the case of a partial retraction, it is possible that the at least one energy storage device 21 of the drive device 12 after the driver 20 has been retracted by continued manual exertion of force in direction (Z) up to the end position of the furniture parts 3a, 3b can be charged, so that the driver 20 (and thus the furniture parts 3a, 3b) can be driven, at least in sections, in the opposite direction to the direction (Z), starting from the end position.

The first guide rail 9 and the second guide rail 13a can be designed together in one piece, wherein the first guide rail 9 and the second guide rail 13a can be connected to one another via an arcuate section. Alternatively, it can be provided that the first guide rail 9 and the second guide rail 13a are designed as separate components, which in the assembly position can either have the same or a different height position. 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.

Fig. 1a shows a possible application of a guide system 2 having a rail arrangement 1 for guiding a first furniture part 3a, preferably in the form of a first door leaf of a folding door, the furniture part 3a being articulated in the assembled position via a vertically extending axis 5a with a second furniture part 3b in the form of a second door leaf connected is. 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 guide system 2 can be used, for example, as a room dividing system, so that in a living room a like in Fig. 1a The furniture body 6 shown in the form of a kitchen block, an office niche, a storage room, a shelf, etc. can be completely covered by the furniture parts 3a, 3b, 4a, 4b and can thus be 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 the furniture parts 3a and 3b, the same statements being valid for the furniture parts 4a, 4b.

The furniture parts 3a, 3b are through the guide system 2 between a first position in which the furniture parts 3a, 3b are aligned essentially coplanar to one another and conceal the furniture body 6, and a second position in which the furniture parts 3a, 3b are essentially parallel are aligned with one another, movable. In this second position, the furniture body 6 is accessible to one person, the two furniture parts 3a, 3b being able to be accommodated in a space-saving manner in an insertion slot 7a located laterally next to the side wall 8a (the left insertion slot 7b for the other furniture parts 4a, 4b can be seen more easily from FIG Drawing).

The rail arrangement 1 comprises a 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 ceiling, a room wall or also to a furniture body, preferably parallel to a front side of the furniture body 6.

Figure 1b shows the in Fig. 1a circled area in an enlarged view. The furniture parts 3a, 3b are connected to a guide device 10, by means of which the furniture parts 3a, 3b are movably supported along the guide rail 9. A carrier 11, which is separate from the guide rail 9, can be seen in the form of a movable slide which, in a transfer position in the longitudinal direction (L), adjoins the guide rail 9 in such a way that the guide device 10 connected to the furniture part 3a is between the guide rail 9 and the carrier 11 is transferable back and forth. 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 points between the guide rail 9 and the carrier 11 and is transferable. 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 linearly displaceable along the guide rail 9, is still on the guide rail 9 in the transfer position of the carrier 11 shown. The carrier 11 is in the transfer position by a locking device 30 ( Figures 7a, 7b ) releasably lockable with the guide rail 9, this locking being releasable by moving the guide device 10 into or onto 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 guide rail 9. The carrier 11 is connected to a vertically extending column 14 which can be moved in the direction (Z) and can be drawn at least in sections in the direction (Z) by a drive device 12. The column 14 can be moved in the direction (Z) along second guide rails 13a and 13b, which in the assembled position are spaced apart from the guide rail 9 in the height direction.

Fig. 2a shows the furniture parts 3a and 3b after this starting from Fig. 1a have been pivoted to one another about the vertical axis 5a and now assume an essentially parallel position to one another. Figure 2b shows the in Fig. 2a circled area in an enlarged view, wherein the guide device 10 is now on the carrier 11 located in the transfer position. It can be provided 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 without a disturbing edge between the Guide rail 9 and the carrier 11 can be moved back and forth. Based on the in Figure 2b The position shown, the carrier 11 together with the guide device 10 (and thus the furniture parts 3a, 3b) can be moved at least in sections in the direction (Z) by the force of a drive device 12.

Fig. 3a 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 attached to the side wall 8a in the direction (Z). On the column 14 there is at least one fitting part 18 for the movable mounting of the furniture part 3b and a bearing part 24 which is fixed relative to the column 14 and on which at least one, preferably several, energy accumulators 21 of the drive device 12 for pulling in the furniture parts 3a, 3b in the direction (Z ) are anchored. In the figure shown, the energy accumulators 21 are each designed as tension springs which act on a driver 20 mounted on the column 14 so as to be pivotable 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 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 draw-in section 23a for partial draw-in of the carrier 11 in the direction (Z) and a tensioning section 23b adjoining the draw-in section 23a for charging the energy storage devices 21 Fig. 3a the energy storage device 21 is in a tensioned state, so that the column 14 (and thus the carrier 11) after the carrier 11 has been unlocked from the guide rail 9 by the force of the relaxing energy storage device 21 along the draw-in section 23a down to the deepest area of the control curve 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 tensioning section 23b of the control cam 23, the energy storage devices 21 being reloaded. 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 switch 25 with an adjusting contour 25c that can be tilted about an axis of rotation 25a is provided, 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. This ensures that the pressure roller 22 pretensioned by the energy storage device 21 does not have to overcome the obstructing draw-in section 23a of the control cam 23 when it moves against the direction (Z), so that the draw-in section 23a can be bypassed by the pressure roller 22 and the force of the energy storage device 21 overflows a longer distance is maintained. Figure 3b shows the in Fig. 3a circled area in an enlarged view.

Figure 4a 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 4b shows the in Figure 4a 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 clamping section 23b of the control cam 23 by manual exertion of force on the movable furniture parts 3a, 3b, so that the energy accumulators 21 are clamped again and can thus be charged. The switch 25, which can be tilted about the axis of rotation 25a, is raised by the pressure roller 22 ( Figure 4c ), 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. Due to the eccentric articulation of the switch 25 around the axis of rotation 25a, a two-armed lever is different formed long lever arm, so that the switch 25 with the longer lever arm, 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. Figure 4d shows the in Figure 4c circled area in an enlarged view.

Figure 5a 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 in the opposite direction (Z). The energy storage devices 21 are fully 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 thus 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 5b shows the in Figure 5a circled area in an enlarged view.

Figure 5c 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 located behind the closed position, the Ejection devices 28 can be moved into an unlocked position, whereupon the column 14 can be moved again in the opposite direction (Z) by the force of the ejection devices 28 and then by the force of the charged energy storage device 21. Fig. 5d shows the in Figure 5c circled area in an enlarged view.

Figure 6a shows a position of the column 14 after ejection by the ejection 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 intake section 23a, but along the adjusting contour 25c arranged or formed on the switch 25. In this way, a uniform ejection process of the column 14 or the furniture parts 3a, 3b is brought about without significant fluctuations in the force of the energy accumulators 21, the force of the energy accumulators 21 being maintained over a longer distance. Figure 6b shows the in Figure 6a 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 intake section 23a.

Figure 6c shows a continued movement of the column 14 in the opposite direction (Z), the pressure roller 22 being moved along the adjusting contour 25c of the switch 25 and the switch 25 being pivoted counterclockwise about the axis of rotation 25a. 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 tensioning section 23a. After the pressure roller 22 has left the adjusting contour 25c of the switch 25 again, 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 cam 23 due to its higher weight is applied.

Figures 7a and 7b 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 guide rail 9 and which can be unlocked by moving the guide device 10 into or onto the carrier 11. The furniture part 3 a is connected to the guide device 10, which can be moved in the longitudinal direction (L) along the guide rail 9. A sliding piece 33 is connected to the guide device 10 in a movement-coupled manner, so that when the guide device 10 moves along the 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 7b ). The coupling lever 35 is rotatably mounted about an axis of rotation 31, a latching element 35c being movable by the coupling lever 35, which engages in a corresponding recess 34 of the guide rail 9 in the locking position and thereby locks the carrier 11 relative to the 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 by a spring (not shown) in the direction of the locking position, 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.

Figures 8a and 8b 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 interacting 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 the carrier 11 is released relative to the guide rail 9 for a movement in direction (Z). The carrier 11 can after unlocking - together with the column 14 - are drawn in at least in sections in the direction (Z) by the force of the energy storage device 21 of the drive device 12 described above, the spacer roller 32 rotatably mounted on the sliding piece 33 for lateral guidance of the carrier 11 in the direction (Z) being able to roll on the side wall 8a.

Figures 9a and 9b show a piece of furniture 37 according to Fig. 1a , which has a fixed furniture body 36 and at least two furniture parts 3a, 3b movably mounted relative to the furniture body 36, in particular door leaves of a folding door, which are articulated to one another in the assembled position via a vertically running axis of rotation 5a. The at least two furniture parts 3a, 3b are between a first position in which the furniture parts 3a, 3b are aligned essentially coplanar to one another by the guide system 2 ( Figure 9b ), and a second position in which the furniture parts 3a, 3b are each aligned essentially parallel to one another ( Figure 9a ) are movable. The furniture 37 can have at least one lateral insertion shaft 7a, 7b in which the furniture parts 3a, 3b, 4a, 4b can be received in the second position. In the figure shown, at least one further furniture body 6 is provided, which is inserted into the furniture body 36 or connected to the furniture body 36, the further furniture body 6 being covered by the movable furniture parts 3a, 3b, 4a, 4b in the first position and in the second position is accessible. The furniture parts 3a, 3b can be moved relative to the guide rail 9 via the guide device 10, while the furniture parts 4a, 4b can be moved along the same guide rail 9 via a separate guide device 10a.

Figure 10a shows the rail arrangement 1 of the guide system 2, wherein the carrier 11 can be locked to the guide rail 9 by the locking device 30 described and, starting from the transfer position, can be moved in a direction (Z) transverse to the longitudinal axis (L). On the side wall 8a, which can partially form the slot 7a, are second guide rails 13a and 13b for the displaceable mounting of the The column 14 connected to the carrier 11 and the drive device 12 attached to the switch 25 which can be tilted about the axis of rotation 25a.

Figure 10b shows the in Figure 10a circled area in an enlarged view, the carrier 11 has already been moved out of the transfer position and has been moved slightly in the direction (Z).
