[0001]    This is a Continuation of application Ser. No. 14/081,727 filed Nov. 15, 2013, which claims priority of European Patent Application No. 12195580.1 filed Dec. 5, 2012. The disclosure of the prior applications are hereby incorporated by reference herein in their entireties. 
     
    
     TECHNICAL FIELD 
       [0002]    The invention relates to a displacement device for slidable and turnable separation elements and to a functional entity with foldable separation elements that are equipped with such a displacement device. 
       BACKGROUND SUMMARY 
       [0003]    Turnable and slidable separation elements are often used for partitioning and closing functional entities. For opening the functional entity, the slidable separation elements are turned, folded and preferably driven into a door compartment. Parked within the door compartment, the separation elements are no longer an obstacle, wherefore the functional entity can freely be accessed. After termination of the work in the functional entity, it can again be closed by pulling the separation elements out of the door compartment and by unfolding and moving the separation elements along the front side of the functional entity. Functional entities can be for example wardrobes or cupboards designed for storing material. Further, functional entities can be working areas or building units, such as a kitchen, that shall be closed after use, in order to prevent further access to the functional entity or in order to present an aesthetical front, instead of the working area. 
         [0004]    [1], U.S. Pat. No. 8,336,972B2, discloses a furniture unit with a displacement device, with which a door, which is pivotally held by a mounting bracket, can be moved from a closed position into a door compartment. The mounting bracket is held vertically aligned when moving in and out of the door compartment by a scissor assembly that comprises two scissor beams that are connected by a joint. In addition, the upper and the lower side of the mounting bracket are connected to carriages that are guided along auxiliary rails that extend inside the door compartment. 
         [0005]    [2], U.S. Pat. No. 8,303,056B2, discloses a wardrobe with a sliding foldaway door, which is foldable and can then be moved into a door compartment. The foldable door comprises a first door wing, which on one side is connected to a mounting bracket, which can be driven into the door compartment and which is pivotally connected on the other side to a second door wing. The second door wing is guided by two guiding devices, the first guiding device pivotally connected above the upper edge of the second door wing and the second guiding device pivotally connected below the lower edge of the second door wing. Further, the guide devices are movable along guide tracks, which extend along the front side of the wardrobe and further into the door compartment. An intermediate panel is arranged between the two door wings, which intermediate panel is connected with hinges to the first and the second door wing. 
         [0006]    The arrangement of guide tracks along the lower side and the upper side of the wardrobe as well as the arrangement of guide carriages at the lower side and the upper side of the second door wing requires significant space and a specific embodiment of the wardrobe. Hence, this device cannot be used universally and is limited to the use in wardrobes that are equipped with the mentioned device elements at the lower side and the upper side. 
         [0007]    Hence, the present invention is based on the object of providing an improved displacement device, with which slidable and turnable separation elements can advantageously be held and operated. 
         [0008]    Further, an improved functional entity with foldable separation elements shall be created, which is equipped with the inventive displacement device. 
         [0009]    The separation elements of the inventive displacement device shall be movable with only one hand with minimal force. Thereby, it shall be ensured, that the process of folding the separation elements can be performed smoothly. Noise and mechanical stresses shall be avoided when operating the displacement device. 
         [0010]    With the inventive displacement device any functional entity, such as wardrobes, cupboards and working areas or building units, particularly kitchen, shall preferably be closable with one or a plurality of separation elements, particularly a plurality of foldable separation elements. 
         [0011]    The inventive displacement device shall not appear distracting and shall require little space. In the state, in which the separation elements are opened, no elements of the displacement device shall be visible. Bezels and covers with which device parts need to be covered shall not be required. 
         [0012]    Furthermore, the separation elements shall firmly be held, so that adjustments can be avoided or reduced to a minimum. However, in the event that an adjustment is required, then little effort shall be required. 
         [0013]    These problems are solved with a displacement device and with a functional entity provided with such a displacement device, which comprise the features of claims  1  and  11 , respectively. Preferred embodiments of the invention, particularly a hinge in a preferred embodiment, are defined in further claims. 
         [0014]    The displacement device comprises a guide carriage that is slidable along a running rail and that is pivotally connectable to a first separation element. 
         [0015]    According to the invention, the guide carriage comprises a carriage body with a carriage head and a carriage foot, which carriage head and carriage foot are connected with one another by a connecting beam. The carriage head holds at least one support wheel and at least two guide wheels and wherein the carriage foot is connected torque proof with a first end piece of a hinge lever, whose second end piece is pivotally held by a hinge shaft that is connectable to a sidewall of the first separation element. 
         [0016]    The hinge lever is connected to the carriage foot and designed in such a way, that the hinge lever holds the guide hinge on the first side or the second side of the rail plate. 
         [0017]    With the inventive displacement device a separation element, e.g. a sliding door made from wood or glass, can firmly be held and moved along a running rail and can simultaneously be turned. In preferred embodiments, the separation element can be turned by 180°, so that, if aligned in parallel to the running rail, the front side or the backside of the separation element is facing the user. Hence, the front side of the separation element can be moved into the one or the other direction along the running rail, whereby the separation element can execute a required rotation. 
         [0018]    The displacement device requires little space and does not engage into the space above the functional entity. The functional entity, e.g. a wardrobe or cupboard, can therefore precisely be fitted into a space provided therefore, without requiring additional space for the displacement device. The displacement device can be inserted in a conventional functional entity that can be installed, in a room without restrictions or limitations. 
         [0019]    In preferred embodiments the at least one support wheel and the guide wheels are arranged on the one side and the guide hinge and the separation element on the other side of the rail plate. In spite of the fact that the displacement device is not arranged outside of the functional entity, the displacement device can be arranged in such a way, that it also does not appear distracting inside the functional entity. Hence, bezels and covers are not required. 
         [0020]    The inventive displacement device can advantageously be installed in any functional entity. In the event that the displacement device holds one separation element only, then the separation element is preferably guided at its lower side as well. For this purpose, guide carriages are used that comprise two guide wheels each, in order to keep the separation element in vertical alignment. The functional entity can comprise one or a plurality of separation elements that can be moved individually by means of the inventive displacement device. After opening the separation elements can for example be aligned side-by-side and can be stapled in a parking area requiring little space. 
         [0021]    Use of the inventive displacement device in a functional entity, which comprises at least a first and a second separation element that are pivotally connected with one another and which can be stored within a door compartment, when the functional entity is opened, is particularly advantageous. The displacement device is mounted laterally at the front side of the leading first separation element and thus can guide the first separation element along a first rail section of the running rail, that runs along the front side the functional entity, and along a second rail section of the running rail, which runs inside the door compartment. During the movement along the running rail, the hinge lever can turn within the guide hinge by 180°, so that the separation element always follows the displacement device that pulls the separation element or is pushed by the separation element. 
         [0022]    In further preferred embodiments, the displacement device is provided with a drive unit, e.g. a drive unit which drives a wheel of the guide carriage or a toothed wheel that engages in a tooth belt that runs in parallel to the running rail and preferably is held within the running rail. The drive devices of this kind are known for example from [3], U.S. Pat. No. 7,578,096B2. With a motorised displacement device, both separation elements can be pulled into or pushed out of the door compartment. Subsequently, the motorised displacement device allows folding and again unfolding the two separation elements. Preferably, the two separation elements are connected with one another via an articulated joint, which holds the two separation elements in symmetrical alignment. I.e., the two separation elements are always inclined by identical angles. Hence, the separation elements can be equipped with a single drive device, which can drive the two separation elements, which are connected with one another, out of the door compartment, can unfold, fold and can drive back the separation elements back into the door compartment. 
         [0023]    Particularly, if heavy separation elements are used, then motorised carriages are preferably mounted on the distal sides of the separation elements. A motorised guide carriage connected to the first separation element can be used for unfolding and folding of the separation elements, while a motorised auxiliary carriage, which is connected to the second separation element, can drive the separation elements into and out of the door compartment. Furthermore, the inventive displacement device can also be used advantageously, when the separation elements are not driven into a door compartment, but are merely stapled in a terminal position or an intermediate position along the running rail. 
         [0024]    Functional entities equipped with the inventive displacement device can manually be operated, since the inventive guiding mechanism requires only a little force. The articulated joint, which connects the two separation elements with one another, is preferably provided with a holding grip, which can manually be operated. By pulling the holding grip, the two separation elements can be pulled out of the door compartment, whereafter the first separation element can further be guided along the first rail section of the running rail by pushing the holding grip back against the functional entity. 
         [0025]    In preferred embodiments the guide hinge comprises a hinge cup, which is recessed at the front sided edge of the first separation element and which preferably exhibits a cup recess, through which the hinge lever can be turned towards the outside. This embodiment ensures that the hinge lever can be turned by 180° against the hinge cup and thus can also the held first separation element can be turned by 180° against the running rail. 
         [0026]    The use of a concealed hinge with a hinge cup recessed in the separation element allows arranging the hinge shaft within the separation element, wherefore a space-saving solution results. However, the use of a concealed hinge is not required, if the hinge shaft can be held within the separation element by other means. For example, a recess can be provided in the separation element, in which a bearing is inserted, with which the hinge shaft is held. Further, the hinge shaft can also be held on the outside of the separation element, so that a concealed hinge is not required. 
         [0027]    The hinge lever preferably comprises a holding sleeve that is held slidable by the hinge shaft. In a preferred embodiment the hinge lever and the hinge cup comprise elements that abut one another without play after the hinge lever has been turned completely into the hinge cup. This feature can be realised for example by providing the hinge cup with a corresponding form. E.g., a recess is embossed into the hinge cup which serves for receiving and holding the hinge lever in the terminal position without play. Alternatively, a cup insert is provided that can be inserted into the hinge cup and that comprises a cup insert recess, into which the hinge lever can be turned and in which the hinge lever is held in the terminal position without play. In this preferred embodiment of the guide hinge a play is provided between the hinge lever and the hinge cup before unfolding the separation elements, which play avoids friction resistances, which otherwise can occur due to minimal differences in the alignment of the separation elements. However, after the separation elements have been folded, they are held precisely without play, so that the separation elements are aligned flush with the other elements of the functional entity, e.g. with the top of the wardrobe. 
         [0028]    In a further preferred embodiment the hinge lever is connected with the carriage body in such a way that the hinge lever is vertically adjustable and/or turnable. By the vertical movement of the hinge lever, the separation elements can be lifted and aligned flush with the upper edge of the wardrobe. By turning the hinge lever, the guide hinge can be shifted towards the guide carriage, until the separation elements abut the walls of the wardrobe. 
         [0029]    For this purpose, the carriage body, i.e. the carriage foot is preferably provided with a bolt chamber. The hinge lever is provided with a lever block, which comprises a threaded bore, into which the bolt shaft of a mounting bolt can be screwed. The bolt shaft is seated within the bolt chamber aligned vertically, i.e. perpendicularly to the running direction of the guide carriage. 
         [0030]    The mounting bolt preferably comprises a bolt head that is seated in a bearing seat provided in the bolt chamber and a cylindrical bolt foot that is inserted into a base opening provided in the bolt chamber. The bolt foot that is extending out of the lower side of the bolt chamber is preferably provided with a coupling element, e.g. a hexagonal opening into which a tool can be inserted, in order to turn the mounting bolt and to shift the hinge lever to a desired height level. 
         [0031]    The lever block, which is pivotally held within the bolt chamber, can preferably be fixed in a desired angular position by means of at least one adjustment screw, preferably two adjustment screws that are coaxially aligned. The at least one adjustment screw is arranged eccentric to the axis of rotation of the mounting bolt, so that a lever is obtained, with which the hinge lever can be turned and fixed. In the selected position, the lever block is then firmly held by the adjustment screw or from opposite sides by the two adjustment screws. 
         [0032]    The displacement device is guided in the running rail preferably in such a way that no elements of the displacement device and the running mechanism are visible after the functional entity, e.g. the wardrobe or the kitchen, has been opened. According to the invention the at least one support wheel and the at least one guide wheel are engaged on the backside of the running rail, which is designed asymmetrically and which comprises a rail plate that is facing the outside of the functional entity. The running rail comprises a rail foot and a rail head that are adjoining the backside of the rail plate and that serve for guiding the support wheels and the guide wheels. The carriage body is connected in such a way to the hinge lever that the hinge cup and therefore the installed first separation element is held in front of the front side of the rail plate. Hence, when opening or folding the separation elements as well as after laterally moving the separation elements, e.g. into the door compartment, only the front side of the rail plate is visible, behind which the guide carriage with the support wheel and the guide wheels is hidden. Hence, the running rail serves also as a bezel, wherefore a separate bezel and related mounting means are not required. 
         [0033]    All in all, a simple, compact, space-saving and cost-efficient set up of the device is achieved. Further, with the use of the inventive displacement device and the running rail a stable setup of the device is obtained, which ensures that also heavier separation elements, particularly foldable separation elements that are connected with one another, can precisely be held and guided. Hence, a guiding device arranged at the lower side of the separation elements is not required. Alternatively, a simplified displacement device or a locking device can be provided at the lower side of the separation elements, which hold and secure the separation elements for example in the terminal position only. 
         [0034]    Below, the invention is described in detail with reference to the drawings.

     DETAILED DESCRIPTION 
       [0059]      FIG. 1A ,  FIG. 1B  and  FIG. 1C  show an inventive displacement device  1 , which comprises a guide carriage  2  guided in a running rail  4  and a guide hinge  3  that is connected to a first separation element  5 A. 
         [0060]    The guide carriage  2  comprises a carriage body  20  with a carriage head  23  and a carriage foot  22 , which are connected with one another by a connecting beam  21 . The carriage head  23  is provided with a horizontal alignment wheel axle  260  serving for holding a support wheel  26  and with two vertically aligned wheel axles  290  serving for holding guide wheels  29 A,  29 B (see  FIG. 3A ). 
         [0061]    The asymmetrically designed running rail  4  comprises a rail plate  41  that is vertically aligned and that connects a rail head  43  and a rail foot  42  with one another. At the upper side of the rail foot  42  a running surface  420  is horizontally extending, on which the support wheel  26  is running. The two guide wheels  29 A and  29 B, which hold the guide carriage  2  in alignment in parallel to the running rail  4 , are guided within the rail head  43 , which exhibits a U-profile that is opened downwards. 
         [0062]    The guide carriage  2  and the guide hinge  3 , which is recessed in a sidewall of the separation element  5 A, are connected with one another via a hinge lever  32 , which is held below the running rail  4 . Hence, the space above the separation element  5 A and above the running rail  4  is kept free, wherefore the displacement device  1  and the running rail  4  can be installed in any functional entity without requiring additional space. 
         [0063]    The separation element  5 A can be moved along the running rail  4  and be turned as desired by up to 180°.  FIG. 1A  shows the separation element  5 A is aligned parallel to the running rail  4 .  FIG. 1B  shows the separation element  5 A opened, i.e. perpendicularly aligned to the running rail  4 .  FIG. 10  shows the separation element  5 A again aligned in parallel to the running rail  4 , however turned by 180° compared to the alignment shown in  FIG. 1A . 
         [0064]      FIG. 1A  shows the guide hinge  3  with a hinge cup  31  that is recessed peripherally in a sidewall of the separation element  5 A and that exhibits a cup recess  312  which is open towards the front face of the separation element  5 A, into which cup recess  312  the hinge lever  32  can be turned, as shown in  FIG. 1C . 
         [0065]      FIG. 1B  shows that after opening and moving the separation element  5 A, only the front side  411  of the rail plate  41  of the running rail  4  is visible, which therefore serves as a bezel. Hence, a separate bezel and related mounting devices are not required. The support wheel  26  and the two guide wheels  29  as well as the functional parts of the rail head  43  and of the rail foot  42  are covered aesthetically advantageous by the rail plate  41  and lie within the functional entity. Hence, after the separation element  5 A has been moved for example into a door compartment, only the rail plate  41  is visible, which is not distracting and which can be provided with a design if required by the user. 
         [0066]      FIGS. 2A, 3A, 3B, 4 and 5  show the displacement device  1  of  FIG. 1A  in different views.  FIG. 2A  shows the displacement device  1  from the side with the carriage foot  22  comprising a bolt chamber  220 , in which a mounting bolt  8  is seated. In bores  311  in the hinge cup  31 , a hinge shaft  35  is seated. The hinge lever  32  is held on one side in the bolt chamber  220  by a mounting bolt  8  and is pivotally held on the other side in the hinge cup  31  by the hinge shaft  35 . The distance “a” or “a*”, respectively, between the longitudinal axes x 8 , x 35  of the mounting bolt  8  and the hinge shaft  35  can be adjusted by turning the hinge lever  32 , which is described below with reference to  FIGS. 5A and 5B . After the adjustment, the hinge lever  32  can be fixed in a desired position by means of adjustment screws  91 ,  92 , which are screwed into threaded bores  2291 ,  2292  provided in the bolt chamber  220  (see  FIG. 4 ). 
         [0067]    The rail head  43  of the running rail  4  comprises a guide channel opened downwards for receiving the guide wheels  29 A. If additional stabilisation of the guide carriage  2  is desired, then the rail foot  42  is may be provided with a guide channel, which can receive two additional guide wheels. E.g., a U-profile that is opened downwards may be provided that exhibits on the upper side the running surface for guiding the support wheel  26 . Hence, the inventive displacement device  1  can interact with different designs of running rails  4 , whereby  FIG. 2A  shows a particularly compact running rail  4 . 
         [0068]      FIG. 2B  shows the displacement device  1  of  FIG. 2A  in an embodiment, in which the separation element  5 A as well as the support wheel  26  and the guide wheels  29  are arranged on the same side  411  of the rail plate  41 . 
         [0069]      FIG. 3A  and  FIG. 3B  show the displacement device  1  of  FIG. 1A  and  FIG. 1B  without separation element. The bolt chamber  220  with mounting bolt  8  inserted therein is shown from two sides. 
         [0070]      FIG. 4  shows the displacement device  1  of  FIG. 1A  with the guide carriage  2  and the guide hinge  3  in an explosion view. The mounting bolt  8 , which comprises a bolt head  81 , a bolt shaft  82  with a threading and a cylindrical bolt foot  83 , has been removed out of the bolt chamber  220 . 
         [0071]      FIG. 5A  shows the bolt chamber  220  with a bearing seat  2281  on the upper side, which exhibits a front sided seat recess  22810 , with a front-sided chamber opening  2201  and on the lower side a chamber base  2202  with a base opening  2283 . The mounting bolt  8  can be inserted through the chamber opening  2201  and to the seat recess  22810  into bolt chamber  220  in such a way that the bolt foot  83  can enter the base opening  2283  and the bolt head  81  can be seated into the bearing seat  2281 . The bolt shaft  82  which holds the hinge lever  32  is freely exposed in the bolt chamber  220  and can be turned by means of a tool, which can be coupled to the bolt foot  83  that is extending out of the bolt chamber  220 . With the engagement of the mounting bolt  8  in the bolt chamber  220 , a release protection is implemented. I.e., the separation element  5 A that is connected to the guide hinge  3  cannot get released self-acting from the guide carriage  2 . Hence, the separation element  5 A can provisorily be engaged in the guide carriage  2  and can then be adjusted conveniently. 
         [0072]      FIG. 4  further shows the detached hinge lever  32 , which comprises a holding sleeve  322  and a lever block  323 , which are connected with one another via an L-shaped lever plate  321 . The holding sleeve  322  has a cylindrical opening  3221 , in which the hinge shaft  35  can be inserted. The lever block  323  comprises a threaded bore  3231 , into which the bolt shaft  82  of the mounting bolt  8  can be screwed. When turning the mounting bolt  8  the lever block  323  held inside the bolt chamber  220  and therefore the separation element  5 A held by the hinge lever  32  is shifted upwards or downwards. Hence, the height of the separation element  5 A can be adjusted. It is further shown that the sidewalls of the bolt chamber  220 , which are opposing one another, are provided with coaxially aligned threaded bores  2291 ,  2292 , into which threaded bolts, i.e. the adjustment screw  91 ,  92 , can be turned. The adjustment screws  91 ,  92  are provided with a coupling element  911  each, such as a hexagonal opening, which can be coupled with a tool. 
         [0073]      FIG. 4  further shows that the cup insert  36  can be inserted into the hinge cup  31 , whose function is described below with reference to  FIGS. 6A-6E . 
         [0074]      FIG. 5  shows the bolt chamber  220  with the adjustment screw  91 ,  92  from a different angle. The mounting bolt  8 , which is connected to the lever block  323  of the hinge lever  32 , can be inserted from the front side into the bolt chamber  220 . The chamber opening  2201  that is provided on the front side is designed in such a way, that the front side of the hinge lever  32  that is held by the mounting bolt  8  can be turned to the left and to the right. 
         [0075]      FIG. 5A  shows the detached hinge lever  32 , which is held by the mounting bolt  8  and the adjustment screws  91 ,  92 , in straight alignment.  FIG. 5B  shows the hinge lever  32 , which is held by the mounting bolt  8  and the adjustment screws  91 ,  92 , inclined. The longitudinal axis x 8  of the mounting bolt  8  and the longitudinal axis x 9  of the adjustment screws  91 ,  92  are located a lever distance “h” apart from one another. By turning the adjustment screws  91 ,  92  the hinge lever  32  can be turned with the result that the distance “a” between a line, which runs in parallel to the running rail  4  and which intersects the longitudinal axis x 8  of the mounting bolt  8 , and the holding sleeve  322  changes. With a clockwise turn of the hinge lever  32  a smaller distance “a*” results with a turn counter-clockwise of the hinge lever  32  a larger distance “a*” results. In total an adjustment range “r” is reached, which allows suitable adjustment of the distance between the separation element  5 A and the running rail  4 . By fastening the two adjustment screws  91 ,  92  the lever block  321  can then be fixed in a selected position. 
         [0076]      FIG. 6A  shows the guide hinge  3  of  FIG. 4  with the hinge cup  31 , in which the cup insert  36  is inserted. The hinge cup  36 , which is preferably made from plastic, comprises a cup insert recess  360  that narrows towards the inside and that exhibits inclined sidewalls  361 , as shown in  FIG. 6B . Hence, the hinge lever  32 , which is adapted to the cup insert recess  360  can be turned into the hinge cup  31 , i.e. into the cup insert recess  360  provided in the cup insert  36 , until it is held in the terminal position by the sidewalls  361  without play. The sidewalls  361 , which are inclined towards the inside, serve as inside slope, which grasp and center the hinge lever  32 , while it is turned into the terminal position. Hence, turning the separation element  5 A held by the hinge lever  32  into the terminal position is executed smoothly without obstacles. 
         [0077]      FIG. 6A  and  FIG. 6C  show the hinge lever  32  released from the cup insert  36  and held by the hinge shaft  35  only. Hence, the hinge lever  32  can be moved along the hinge shaft  35  upwards and downwards. When turning the separation element  5 A, e.g. during the folding process of the two pivotally connected separation elements  5 A,  5 B shown in  FIG. 8 , the hinge lever  32  is released from the cup insert  36  and therefore exhibits mechanical play and is movable, in order to compensate misalignments, which can occur under load or after a longer period of operation. Hence, the inventive displacement device  1  provides optimal running properties. 
         [0078]      FIG. 6D  shows the hinge lever  32  while turning into the cup insert recess  360  provided in the cup insert  36 .  FIG. 6E  shows the hinge lever  32  held in the terminal position without play by the cup insert  36 . 
         [0079]    The inventive displacement device  1  can advantageously be installed in different functional entities, particularly conventional and standardised functional entities. The inventive displacement device can be installed for example in building units, such as kitchens, or wardrobes, which can be closed by foldable separation elements that, after opening, can be folded and be shifted into a door compartment. 
         [0080]      FIG. 7  and  FIG. 8  show a wardrobe or a cupboard  5  with sidewalls  5 C,  5 D, with a cover plate  5 E and with a first and a second separation element  5 A,  5 B, which are connected to one another by joints  70  and which are foldable and can be moved into a door compartment  55 . The leading first separation element  5 A is holding on the front side an inventive displacement device  1  and is movable along a running rail  4 , as shown in  FIG. 1A . The two separation elements  5 A,  5 B are provided with connecting hinges  30  at the sides facing one another. The connecting hinges  30  comprise a connecting hinge lever  320  each, which are pivotally connected pairwise by an articulated shaft  73 , as shown in  FIG. 10A  and  FIG. 10B  and also shown in  FIG. 11-14 . Two connecting hinges  30  each and the articulated shaft  73 , which connects the connecting hinge levers  320 , form a joint  70 . 
         [0081]    The second separation element  5 B is connected on the other side with bracket hinges  30 ′ to a mounting bracket  61 , which is held in vertical alignment by a scissor assembly  62  and which, in this preferred embodiment, is movable within the door compartment  55  by means of auxiliary carriages  63 . 
         [0082]      FIG. 8  shows the wardrobe or cupboard  5  of  FIG. 7  from above with the running rail  4 , which extends with a first rail section  45  along the front of the wardrobe  5  and further with a second rail section  455  into the door compartment  55 , into which the foldable separation elements  5 A,  5 B can be entered. The door compartment  55 , which is laterally delimited by a wardrobe wall  5 D and an outer wall  5 F, is dimensioned in such a way that the two separation elements  5 A,  5 B can be received. Hence, the running rail  4 , which consists of one or more rail elements, extends practically without intersection or transition from a first terminal position to a second terminal position of the displacement device  1 . The inventive guide hinge  3  thereby allows, turning the first separation element  5 A relative to the guide carriage  2  by 180°, so that the guide carriage  2  can run ahead when closing or opening the separation elements  5 A,  5 B. 
         [0083]    In a preferred embodiment the guide carriage  2  can be provided with a drive unit A 1  as mentioned above. For this purpose the two separation elements  5 A,  5 B are connected with one another by an articulated joint  70 , which holds the two separation elements in symmetrical alignment. In a further embodiment, the two distal sides of the separation elements  5 A,  5 B are connected to motorised carriages. A motorised carriage  2  connected to the first separation element  5 A can be used for folding and unfolding the separation elements  5 A,  5 B, while a motorised auxiliary carriage  63  connected to the second separation element  5 B can drive the separation elements  5 A,  5 B into and out of the door compartment  55 . In further arrangements the guide carriage  2  and the auxiliary carriage can be driven towards one another at first and then together along the running rail  4 , e.g. into a park room or staple room. For controlling the drive unit A 1  or the drive units A 1  and A 2  a control unit C is provided. 
         [0084]      FIG. 9  shows a part of the wardrobe  5  of  FIG. 8 , without separation elements  5 A,  5 B and without sidewalls with a view to the auf the exposed door compartment  55 , into which the running rail  4  extends and in which a lower (not shown) and an upper auxiliary rail  40  are mounted, along which the mounting bracket  61  can be driven by means of auxiliary carriages  63 . The mounting bracket  61  is held in vertical alignment preferably by a scissor assembly  62 . Further device is known, with which the mounting bracket can be held in vertical alignment. 
         [0085]      FIG. 10A  shows partly the two separation elements  5 A,  5 B, which are connected with one another by connecting hinges  30  and articulated shafts  73 .  FIG. 10A  and  FIG. 10B  show that the connecting hinge levers  320  of the connecting hinges  30  are provided with hinge sleeves, which are coaxially aligned and are traversed by an articulated shaft  73 . The articulated shafts  73  hold clamps  72  that engage in an intermediate bracket  71 , which covers the free space between the two separation elements  5 A and  5 B. 
         [0086]      FIG. 10C  shows the two connecting hinges  30  and the articulated shaft  73  of  FIG. 10A . Further, a wedge shaped clamp  72  is shown, which engages in a form locking manner into the intermediate bracket  71  and is slidably held therein and which can be locked by a bridge-shaped locking element  74 . The wedge shaped clamp  72  exhibits an axial bore  721 , into which a bearing sleeve  720  can be inserted, which serves for receiving the articulated shaft  73 . The wedge shaped clamp  72  further comprises a threaded bore  722 , which serves for receiving a locking screw  741 , with which the wedge shaped clamp  72  can be pulled against the locking element  74 , which is supported by the intermediate bracket  71 . Thereby the wedge shaped clamp  72  is also connected by force to the intermediate bracket  71  and can no longer be shifted axially. 
         [0087]    Hence, the intermediate bracket  71  is connected in a form locking manner to the articulated shaft  73  and therefore with the connecting hinges  30 . Hence, for moving the separation elements  5 A,  5 B the intermediate bracket  71  can be grasped, which is preferably provided with a holding element  700 , as shown in  FIG. 8 . Even under the impact of considerable forces, the intermediate bracket  71  is firmly held by the connecting hinges  30 . 
         [0088]    Hence, in the event that no electrical drive unit is provided, the two separation elements  5 A,  5 B can be pulled out of the door compartment  55 , can be unfolded, and can be folded and pushed back into the door compartment  55  by means of the holding element  700 .
