Description

The present invention relates to a device for operating wing doors of a cupboard, a chest of drawers or a container, comprising a body and at least two door leaves each pivotably mounted on the body about a vertical axis. The device has a transmission which couples a first door leaf to at least one second door leaf, so that an actuation of the first door leaf brings about a forced actuation of the at least one second door leaf. The transmission comprises a deflection gear which diverts a tensile force or thrust force acting on the first door leaf into a thrust force or tensile force acting on the at least one second door leaf. The transmission has a pivot lever mounted on the body of the cabinet, chest of drawers or container so that it can rotate about an axis of rotation, the pivot axis running parallel to the vertical axes of the door leaves, and the door leaves each being articulated at a pivot point on the pivot lever. The axis of rotation of the reversing lever has different distances from the vertical axes of the door leaves.

The invention also relates to a cupboard, a chest of drawers or a container with hinged doors, comprising a body and at least two door leaves, each pivotably mounted on the body about a vertical axis, with a forced coupling of the double doors via a device of the type mentioned above.

Cabinets, chests of drawers and containers with double doors are known from the prior art in different configurations. In particular, the cabinet can be a steel cabinet, plastic cabinet, wooden cabinet, wood-based cabinet, locker, tool cabinet, filing cabinet, kitchen cabinet, living room cabinet, bedroom cabinet, pantry or the like made of metal, plastic, wood or a wooden material. Currently, the door leaves have to be manually operated individually by a user. For this purpose, the user needs both hands to operate several door leaves, which is impractical because objects that are to be placed in the cabinet or have been removed from it have to be set down in order to operate the door leaves. Alternatively, if the wing doors are operated with one hand, the door wings can only be operated one after the other, which is cumbersome and time-consuming. Even if the door leaves are provided with handles, in practice it is the case that at most the first door leaf is gripped on the handle for actuation. The at least one second door leaf is then simply gripped from behind on the edge facing the first door leaf, which leads to ugly and unhygienic fingerprints on the edge of the at least one second door leaf that is gripped behind. A further disadvantage of the prior art is that the door leaves are not secured in their open position, so that they can automatically leave this position unintentionally. In particular, if the inside of the cabinet contains drawers that are pulled out when the door leaves are open, the insides of the door leaves can then be damaged, and under certain circumstances even damage to the hinges with which the door leaves are pivotably connected to the body about the vertical axes , come.

From the US 2009/145 031 A1 a device for operating wing doors of an oven is known, which has a device with a transmission which couples a first door leaf with at least one second door leaf, so that an actuation of the first door leaf brings about a forced actuation of the at least one second door leaf. A closing aid is assigned to the gear mechanism, so that gentle actuation of an open door leaf and overcoming a dead center is sufficient to move both door leaves into the closed position with the aid of the spring-assisted closing aid.

Proceeding from the described prior art, the present invention is based on the object of improving the actuation of the door leaves of a cabinet, a chest of drawers or a container with wing doors.

To solve this problem, a device for actuating wing doors having the features of claim 1 is proposed. In particular, it is proposed that, based on the device of the type mentioned at the outset, a damping element for damping a closing and / or opening movement of the door leaves is assigned to the reversing lever.

The object on which the present invention is based is also achieved by a cupboard, a chest of drawers or a container with hinged doors having the features of claim 19. In particular, it is proposed that the cabinet, the chest of drawers or the container of the type mentioned at the beginning have a device according to the invention for operating the wing doors.

The invention thus relates to a fitting for a cupboard or the like with wing doors, the at least one second door wing being automatically and forcibly also activated when a first door wing is operated. The door leaves are coupled to one another via a corresponding gear so that the desired effect occurs. The transmission can be designed in different ways in order to achieve the effect. In particular, it is conceivable that the transmission cables, gears, rotary levers with toothed ring, reversing lever, linear or Curve guides, push / pull rods, guide arms or the like in different combinations. One advantage of the present invention is that several door leaves of a cabinet or the like with hinged doors can be operated (opened or closed) with just one hand in a particularly time-saving manner. By actuating the first door leaf, the at least one second door leaf is automatically and forcibly also actuated. A separate actuation of the at least one second door leaf of the cabinet or the like is not required.

The transmission comprises a deflection gear which diverts a tensile force or thrust force acting on the first door leaf into a thrust force or tensile force acting on the at least one second door leaf. There are various possibilities for implementing the deflection gear, some of which are explained in more detail below.

The transmission has a pivot lever mounted on the body of the cabinet, chest of drawers or container so that it can rotate about an axis of rotation, the pivot axis running parallel to the vertical axes of the door leaves, and the door leaves each being articulated at a pivot point on the pivot lever. The axis of rotation advantageously has the same distance from the vertical axes of the door leaves. To operate the wing doors, a user grabs the first door wing of the closed wing doors with a handle or the like and opens the door wing. As a result, the lever, to which the first door leaf is hinged, e.g. via a first push / pull rod, is set in a rotary movement around the axis of rotation (e.g. clockwise). This rotary movement generates a pushing force which acts on the at least one second door leaf, on which the deflection lever is articulated, for example via a second push / pull rod, which causes the door leaf to open. In a corresponding manner, the user grabs the first door leaf of the opened leaf doors by a handle or the like and closes the door leaf. This sets the lever in a rotary movement around the axis of rotation (e.g. counterclockwise). This rotary movement generates a tensile force acting on the at least one second door leaf, which causes the door leaf to close. This ensures that the door leaves are operated synchronously.

The damping element assigned to the reversing lever serves to dampen a closing and / or opening movement of the door leaves. The fitting for the cabinet or the like therefore has a damping element which dampens an opening movement and / or a closing movement of the door leaves towards the end of the movement and thus ensures a gentle, low-noise approach of the door leaves to the open or closed position. By coupling the door leaves via the gearbox, it can be sufficient if the damping element only acts on the reversing lever. The damping element can be designed, for example, as a gas pressure, oil, fluid, air damper or any other type of damper. The damper element can be an integral part of the transmission.

The transmission can be designed to forcibly actuate the at least one second door leaf at the same time as the first door leaf when the first door leaf is actuated. A transmission designed in this way ensures that the door leaves are opened synchronously.

However, the gear mechanism can also be designed to forcibly actuate the at least one second door leaf at a time offset from the first door leaf when the first door leaf is actuated. A transmission designed in this way ensures that the door leaves are opened asynchronously. This can be useful, for example, if the first door leaf closes over the at least one second door leaf and covers the lateral edge of the at least one second door leaf directed towards the first door leaf in the closed position.

Furthermore, the gear mechanism can be designed to secure the door leaves coupled to one another in this position after the door leaves have reached an open position, so that they cannot leave this position automatically. The door leaves are preferably secured in the open position automatically after the open position has been reached. This can be implemented, for example, by a spring load acting on the gear mechanism in the closed position of the door leaves. This has the advantage that the opened door leaves cannot close again by themselves from the open position. If the cabinet or similar has drawers, this prevents the inside of the door leaves from being damaged by pulled out drawers. To close the door leaves secured in the open position or to open the door leaves secured in the closed position, the securing forces, for example the spring forces, simply have to be overcome. The securing forces can be applied, for example, by the damping element.

According to an advantageous development of the invention, it is proposed that the deflection lever is variable in length and interacts with a guide mechanism, so that the deflection lever runs through phases of different lengths when it passes through a closing or opening movement between a closed and an open position of the door leaves, the deflection points being linear Go through movement that is perpendicular to the surface extension of the door leaves in their closed position.

According to a preferred embodiment, it is proposed that the deflection lever has at least two lever elements which can be displaced longitudinally relative to one another, the damping element being fastened with a first end to a first lever element and a second end to another lever element. Preferably, the axis of rotation of the deflection lever is on one of the lever elements and the deflection point or points via which the door leaves are articulated on the deflection lever are arranged on another lever element. The lever elements can be designed to be displaceable relative to one another by means of guide elements arranged centrally or laterally. Central guide elements can be implemented, for example, by a guide slot formed centrally along a longitudinal extension of one of the lever elements and a guide pin guided therein so as to be longitudinally displaceable on another lever element. Lateral guide elements can be implemented, for example, by lateral guide legs of two lever elements which can be displaced relative to one another, wherein the guide legs of one of the lever elements can slide with their outer surfaces on the inner surfaces of the guide legs of the other lever element. Sliding elements, for example balls of a ball bearing, rollers of a roller bearing, sliding coatings (for example made of plastic, in particular polytetrafluoroethylene (PTFE)), can be arranged between interacting guide elements.

The guide mechanism with which the deflection lever cooperates in order to realize the linear movement of the deflection points via which the door leaves are articulated on the deflection lever can be designed differently. In principle, for reasons of cost and stability, simple guide mechanisms are to be preferred, but more complex guide mechanisms are also conceivable. It is proposed, for example, that the guide mechanism comprises a curved guide. At least one of the lever elements of the deflection lever, preferably that lever element at which the deflection points, via which the door leaves are hinged to the deflection lever, are arranged, is guided in a non-linear, preferably arcuate guide element. During an actuation movement (i.e. opening or closing movement) of the door leaf, the guided lever element is guided relative to the at least one other lever element in such a way that the deflection points execute a linear movement that runs perpendicular to the surface extension of the door leaves in their closed position. In this way, synchronous actuation of both door leaves can be realized.

It would also be conceivable that the guide mechanism comprises a lever guide. Several levers, which together form the lever guide, can be articulated on the deflection lever so that the deflection points when the door leaves are actuated (open or close) perform a linear movement that runs perpendicular to the surface extension of the door leaves in their closed position. In this case, the reversing lever is not mounted directly on the body of the cabinet or the like, but rather indirectly via at least one of the levers. The levers of the lever guide include, for example, a control arm and a compensating arm. Both arms are hinged to the reversing lever so that they can rotate at a distance from one another. With their end opposite the reversing lever, the arms are also rotatably attached to the body of the cabinet or the like, in particular to the ceiling or the floor of the body.

Finally, it would also be conceivable for the guide mechanism to include a linear guide which runs perpendicular to the surface extension of the door leaves in their closed position. In particular, the lever element on which the deflection points of the door leaves are arranged is guided in the linear guide, so that the deflection points execute the desired linear movement when the door leaves are actuated (opened or closed). For example, a guide head can be formed on the deflection lever, which is guided in the linear guide and on which the deflection points are formed.

According to an advantageous development of the invention, it is proposed that the transmission is assigned a support element that supports an actuation movement of the door leaves coupled to one another from a closed position to an open position and / or vice versa, so that after overcoming a dead point at the beginning of the actuation movement, the remaining actuation movement is carried out automatically. The support element is preferably designed as a compression spring element. If the damping element is designed, for example, as a gas pressure, oil, fluid, air damper or the like, it can for example also simultaneously realize the function of the support element. In this way, a damping and a support function can be realized by a single element. The support element can also hold the door leaves in their closed and / or open position.

To open the door leaves from the closed position, a door leaf is first opened against the force of the damper / support element. By coupling the door leaves by means of the gear, the second door leaf is forcibly opened at the same time. After overcoming a dead center, for example at an opening angle of the door leaf of around 45 °, the pressure force of the damper / support element acts supportively on the lever and thus on the door leaf and ensures the further movement of the door leaf into the open position or supports the opening movement. Due to the pressure force still acting, the door leaves are held in the open position by the damper / support element. To close the door leaves, one of the door leaves is again first moved against the force of the damper / support element in the direction of the closed position. By coupling the door leaves by means of the gear, the second door leaf is forcibly closed as well. After the dead center has been overcome, the pressure force of the damper / support element has a supporting effect on the reversing lever and thus on the door leaves and ensures the further movement of the door leaves into the closed position or supports the closing movement. Due to the pressure force that continues to act, the door leaves are held in the closed position by the damper / support element.

According to this development, the fitting for the cabinet or the like has a support element which supports an opening movement and / or a closing movement of the door leaves. By coupling the door leaves via the gearbox, it can be sufficient if the support element only acts on one of the door leaves or the deflection lever. The support element can be designed, for example, as a spring element (spiral spring, gas pressure spring or the like) that is an integral part of the transmission. The support element can, for example, be articulated at one end to the body of the cabinet or the like and at its other end to the deflecting lever. A force development direction (for example in the longitudinal extension) of the support element preferably runs obliquely to the longitudinal extension of the deflection lever so that a spring force acting on the deflection lever can support or cause the door leaves hinged to the deflection lever to open or close. The support element is preferably an integral part of the reversing lever, i.e. its direction of force development runs parallel to a longitudinal extension of the reversing lever. In particular, it is proposed that one end of the support element is arranged on one of the lever elements and the other end of the support element is arranged on another lever element.

According to a first embodiment of the invention it is proposed that the transmission has a guide head linearly guided on the body of the cabinet or the like, the linear guide of the guide head running perpendicular to the surface extension of the door leaves in its closed position and the door leaves each having a thrust - / pull rod are hinged to the guide head. A user grabs the first door leaf of the closed wing doors with a handle or the like and opens the door leaf. The tensile force is transmitted to the guide head via a first push / pull rod via which the door leaf is hinged to the guide head and the latter is moved in its linear guide in the direction of the door leaf. The movement of the guide head also moves a second push / pull rod via which a second door leaf is articulated to the guide head, a pushing force of the guide head being transmitted to the second door leaf, which is also automatically opened. In a corresponding manner, the user grabs the first door leaf of the opened leaf doors by a handle or the like and closes the door leaf. A pushing force is transmitted to the guide head via the first push / pull rod and the latter is moved away from the door leaves in its linear guide. The movement of the guide head also moves the second push / pull rod, a tensile force of the guide head being transmitted to the second door leaf, which is also automatically closed. This embodiment ensures synchronous actuation of the door leaves.

It is conceivable to design the linear guide and the guide head as a conventional drawer guide, a static guide rail being attached to the body and a guide rail movable relative to the static guide rail forming the guide head to which the push / pull rods are articulated. The drawer slide can have a closing aid, so that a gentle actuation of the opened first door leaf and overcoming a dead point is sufficient to move the door leaves into the closed position with the aid of the closing aid. Furthermore, the drawer slide can have at least one damping element in order to dampen the door leaves towards the end of the closing movement and / or the opening movement and to let them slide slowly into the closed or open position.

According to a second embodiment of the invention, it is proposed that the transmission has a guide head guided linearly on the body of the cabinet or the like, the linear guide of the guide head running perpendicular to the surface extension of the door leaves in its closed position and the door leaves each having a the guide head rotatably mounted about an axis of rotation with a ring gear are articulated, wherein the axis of rotation is arranged in a center of the ring gear and runs parallel to the vertical axes of the door leaves, the door leaves are articulated to an end of the respectively assigned rotary lever opposite the ring gear and the toothed ring of the rotary lever assigned to the first door leaf is in engagement with the toothed ring of the rotary lever assigned to the at least one second door leaf. It is conceivable that the door leaves each directly (or via a linear guide) at the end of each of them opposite the toothed ring associated rotary lever are articulated. Advantageously, the door leaves are each articulated via a guide arm fastened to the door leaves at a fixed angle to the end of the rotary lever assigned to them opposite the ring gear. The angle is preferably 90 °, so that the guide arms each protrude perpendicularly from the corresponding door leaf, but can also be an angle that deviates therefrom. The guide arms of the first door leaf and of the at least one second door leaf can be attached to the door leaves at the same or at different angles.

In this embodiment, a user grabs the first door leaf of the closed leaf doors by a handle or the like and opens the door leaf. A first rotary lever is set into rotation about its axis of rotation (clockwise) via a first guide arm which is attached to the first door leaf. This rotation is transmitted to the first rotary lever via the ring gear and a ring gear of a second rotary lever, so that the latter is set into rotation about its axis of rotation (counterclockwise). The guide head can be moved on its linear guide. The rotation of the second rotary lever is transmitted to a second guide arm, which is attached to the second door leaf, and the second door leaf is also opened. In a corresponding manner, the user grabs the first door leaf of the opened leaf doors by a handle or the like and closes the door leaf. The first rotary lever is set into rotation about its axis of rotation (counterclockwise) via the first guide arm. This rotation is transmitted via the ring gear of the first rotary lever and the ring gear of the second rotary lever to the latter, so that the latter is set into rotation about its axis of rotation (clockwise). The guide head can be moved on its linear guide. The rotation of the second rotary lever is transmitted to a second guide arm and the second door leaf is also closed. This embodiment ensures synchronous actuation of the door leaves.

According to a third embodiment of the invention, it is proposed that the gear mechanism for each door leaf has a rotary lever with a toothed ring mounted on the body of the cabinet, the chest of drawers or the container so that it can rotate about an axis of rotation, the axis of rotation being arranged in a center of the toothed ring and parallel to the Vertical axes of the door leaves, the door leaves being articulated on an end of the respective rotary lever assigned to them opposite the toothed ring, and the toothed ring of the rotary lever assigned to the first door leaf engaging the toothed ring of the rotary lever assigned to the at least one second door leaf. It is conceivable that the door leaves are each articulated directly (or via a linear guide) to the end of the rotary lever assigned to them opposite the toothed ring. Advantageously, the door leaves are each articulated via a push / pull rod to the end of the rotary lever assigned to them opposite the toothed ring.

In this embodiment, a user grabs the first door leaf of the closed leaf doors by a handle or the like and opens the door leaf. A first push / pull rod, which is articulated on the first door leaf and on a first rotary lever, causes the first rotary lever to rotate around its axis of rotation (clockwise). This rotation is transmitted to the first rotary lever via the ring gear and a ring gear of a second rotary lever, so that the latter is set into rotation about its axis of rotation (counterclockwise). The rotation of the second rotary lever is transmitted to a second push / pull rod which is articulated to the second rotary lever and the second door leaf, and the second door leaf is also opened. In a corresponding manner, the user grabs the first door leaf of the opened leaf doors by a handle or the like and closes the door leaf. The first rotary lever is set in rotation around its axis of rotation (counterclockwise) via the first push / pull rod. This rotation is transmitted via the ring gear of the first rotary lever and the ring gear of the second rotary lever to the latter, so that the latter is set into rotation about its axis of rotation (clockwise). The rotation of the second rotary lever is transmitted to a second push / pull rod and the second door leaf is also closed. This embodiment ensures synchronous actuation of the door leaves.

According to a fourth embodiment of the invention, it is proposed that the transmission for each door leaf has a gear wheel rotatably mounted on the body of the cabinet, chest of drawers or container about an axis of rotation, the axis of rotation running parallel to the vertical axis of the door leaf, with the first door leaf associated gear is in engagement with the gear associated with the at least one second door leaf, and a toothed rack is articulated on the door leaves, which, when the door leaves are actuated, rolls with their teeth on the gear associated with the corresponding door leaf. A user grabs the first door leaf of the closed wing doors with a handle or the like and opens the door leaf. A first toothed rack, which is hinged to the first door leaf, slides with its teeth over a first gearwheel and sets it in a rotary movement around its axis of rotation (clockwise). The first rack is preferably spring-loaded onto the outer circumference of the first gear pressed. This rotation is transmitted via the teeth of the gearwheels to a second gearwheel, which is set in a rotary motion around its axis of rotation (counterclockwise). This rotary movement is transmitted to the second toothed rack, which is articulated on the second door leaf, via the teeth of the second gearwheel, which mesh with teeth of a second toothed rack, preferably spring-loaded. This is moved along its length and the movement is transferred to the second door leaf so that it is also opened. In a corresponding manner, the user grabs the first door leaf of the opened leaf doors by a handle or the like and closes the door leaf. The first toothed rack slides with its teeth over the first toothed wheel, causing it to rotate around its axis of rotation (counterclockwise). This rotation is transmitted via the teeth of the gear wheels to the second gear wheel, which is set in a rotary motion around its axis of rotation (clockwise). This rotary movement is transmitted to the second toothed rack via the teeth of the second gearwheel, which mesh with teeth of the second toothed rack. This is moved along its longitudinal extension and the movement is transferred to the second door leaf so that it is also closed. This embodiment ensures synchronous actuation of the door leaves.

According to a fifth embodiment of the invention it is proposed that the transmission has a guide arm fastened to the first door leaf at a fixed angle, the at least one second door leaf being articulated to the guide arm via a push / pull rod, the push / pull rod is articulated on the one hand to the at least one second door leaf and on the other hand to an end of the guide arm opposite the first door leaf. The angle is preferably 90 °, so that the guide arm protrudes perpendicularly from the first door leaf, but it can also be an angle that deviates therefrom. The guide arm is preferably fastened at a distance from a hinge via which the first door leaf is hinged to the body of the cabinet, chest of drawers or the container, or from the corresponding vertical axis on the first door leaf. The push / pull rod is preferably at a distance from a hinge via which the at least one second door leaf is articulated on the body of the cabinet, chest of drawers or container, or articulated to the corresponding vertical axis on the at least one second door leaf.

To operate the wing doors, a user grabs the first door wing of the closed wing doors with a handle or the like and opens the door wing. The guide arm moves together with the first door leaf, with a deflection point of the guide arm, to which the push / pull rod is articulated, moves on a circular path around the vertical axis of the first door leaf (counterclockwise). A pushing force acts on the push / pull rod, which transfers the pushing force to the at least one second door leaf to which the push / pull rod is articulated, so that the door leaf is opened. In a corresponding manner, the user grabs the first door leaf of the opened leaf doors by a handle or the like and closes the door leaf. The guide arm moves together with the first door leaf, the deflection point of the guide arm, to which the push / pull rod is hinged, moves on the circular path around the vertical axis of the first door leaf (clockwise). A tensile force acts on the push / pull rod, which transmits the tensile force to the at least one second door leaf so that the door leaf is closed. This embodiment ensures synchronous actuation of the door leaves.
wherein the door leaves are each articulated at different pivot points on the pivot lever. Preferably, the deflection points each have, viewed in a plane, at least in one direction, different distances from the axis of rotation of the deflection lever. Particularly preferably, when viewed in the plane, the deflection points have different distances from the axis of rotation of the deflection lever in two mutually perpendicular directions. According to a seventh embodiment, it is proposed that the axis of rotation of the reversing lever have different distances from the vertical axes of the door leaves. In this case, the door leaves can be articulated at the same or at different deflection points on the deflection lever. The door leaves are preferably articulated to the reversing lever via push / pull rods. The push / pull rods can have the same or different lengths. This embodiment particularly ensures asynchronous actuation of the door leaves. However, it can also be designed in such a way that it effects synchronous actuation of the door leaves.

In the 1 to 18th and 21st to 29 each shows a cupboard, a chest of drawers or a container with hinged doors. The following text is representative of any type of cabinet, chest of drawers or container with double doors as an example of a cabinet. The cabinet can, for example, as a steel cabinet, plastic cabinet, wooden cabinet, wood-based cabinet, a locker Tool cupboard, a filing cabinet, a kitchen cupboard, a living room cupboard, a bedroom cupboard, a pantry or the like can be made of metal, plastic, wood or a wood-based material. Of course, the present invention can also be used in cabinets made from other materials or from a combination of several materials (eg body made of wood and door leaves made of metal).

In the figures, the cabinet in its entirety is denoted by the reference number 2 designated. The cabinet comprises a body 4th , of which only side walls in the figures 6 and back wall 8th can be recognized. The body also includes 4th a top wall and a bottom wall. In the body 4th Shelf boards made of wood, a wood-based material, metal, glass or another material and / or drawers made of wood, metal, glass or another material can be arranged. The cabinet also includes 2 several door leaves 10 that by means of hinges 12th around vertical axes 14th pivotable on the body 4th , preferably the front edge of the side walls 6 , are hinged. Instead of hinges 12th any kind of door hinge can also be used. It is also conceivable that the hinges 12th Arbitrarily designed so that a door leaf 10 for example. Can be pivoted about several different vertical axes. In the exemplary embodiments shown, the door leaves 10 the same dimensions. However, it would also be conceivable that the door leaves 10 have different dimensions and geometries.

To operate the door leaves 10 of the closet 2 To improve, in particular to make it easier and faster, the invention proposes a device for operating the door leaves of the cabinet 2 before that a gear 20th has, which the first door leaf 10a with at least one second door leaf 10b couples so that an actuation of the first door leaf 10a a forced actuation of the at least one second door leaf 10b causes. The invention is described below using a cabinet 2 with two door leaves 10 described. With an appropriate design of the transmission 20th however, it would also be conceivable to use the forced opening described for cabinets 2 with more than two door leaves 10 to use.

The device can therefore be used as a special fitting for the cabinet 2 are described, with the help of which when the first door leaf is operated 10a the second door leaf 10b is automatically and forcibly also operated. The door leaves are over the gear 20th coupled together so that the desired effect occurs. The gear 20th can be designed in different ways to achieve the effect. In particular, it is conceivable that the transmission 20th Cable pulls, gears, rotary levers with ring gears, deflection levers, linear or curved guides, push / pull rods, guide arms, hydraulic cylinders, gas cylinders, fluid cylinders, air cylinders or the like in different combinations. An advantage of the present invention is that multiple door leaves 10 of a closet 2 with wing doors, can be operated (opened or closed) with just one hand, saving time. By operating the first door leaf 10a the second door leaf is automatically and compulsorily 10b actuated. A separate manual operation of the second door leaf 10b not necessary.

Depending on the design of the transmission 20th the device can be used for simultaneous (synchronous) or staggered (asynchronous) actuation of the door leaves 10 to care. Asynchronous actuation can be useful, for example, when the first door leaf 10a above the second door leaf 10b closes and one to the first door leaf 10a directed lateral edge (e.g. the edge 11 ) of the second door leaf 10b covered in the closed position.

It is suggested that the transmission 20th comprises a deflection gear, which one on the first door leaf 10a Acting tensile force (when opening the first door leaf 10a ) or thrust (when closing the door leaf 10a ) into one on the second door leaf 10b acting thrust (when opening) or tensile force (when closing) diverts. There are various possibilities for implementing the deflection gear, some of which are explained in more detail below.

A first version of a first embodiment of the invention is shown in FIGS 1 to 4th shown. The gearbox 20a one on the body 4th of the closet 2 , especially on the inside or outside of the top wall of the body 4th , on a guide rail 22nd linearly guided guide head 24 on. Alternatively, the guide head 24 also on a lid, top panel, false ceiling, sub-floor, intermediate floor, but also on a rear wall or front panel of the cabinet 2 be arranged. The rail 22nd can at their ends 22a and 22b on the body 4th be attached, for example. By means of screws. The linear guide of the guide head 24 runs perpendicular to a surface extension of the door leaf 10 in their closed position (cf. 3 ). The door leaves 10 are each on the guide head 24 hinged. The linkage can be direct or indirect, for example via a push / pull rod 26th respectively.

To open the wing doors (cf. 1 ) a user grabs the first door leaf 10a the closed wing doors (cf. 3 ) on a handle section 28 , for example in the form of a handle, and opens the door leaf 10a in the direction of an arrow 30th . Via the first push / pull rod 26a over which the door leaf 10a on the guide head 24 is hinged, becomes a pulling force 32 on the guide head 24 transfer. This is in its linear guide in the direction of the door leaf 10 moved towards. The movement of the guide head 24 moves a second push / pull rod 26b over which the second door leaf 10b on the guide head 24 is hinged. There is a thrust 34 from the guide head 24 on the second door leaf 10b which will automatically open it.

In a corresponding manner, the user takes hold of the wing doors to close (cf. 2 ) the first door leaf 10a the opened double doors (cf. 4th ) on the handle section 28 and closes the door 10a in the direction of an arrow 36 . Via the first push / pull rod 26a becomes a thrust 38 on the guide head 24 and this in its linear guide from the door leaves 10 moved away. The movement of the guide head 24 also moves the second push / pull rod 26b , being a tensile force 40 from the guide head 24 on the second door leaf 10b and this is automatically closed.

In the first embodiment shown, the turning points are between the guide head 24 and the push / pull rods 26th with the reference number 42 and the turning points between the push / pull rods 26th and the door leaves 10 with the reference number 44 designated. This embodiment ensures synchronous actuation of the door leaves 10 . The push rods 26th have the same length. The turning points 42 , 44 are mirror-symmetrical to a vertical center plane running through the plane of the drawing 46 arranged which the guide rail 22nd includes and between the door leaves 10 runs in the closed position. However, if you use the push / pull rods 26th selects different lengths and / or the deflection points 42 , 44 asymmetrical to the median plane 46 arranges, could with the transmission 20a an asynchronous actuation of the door leaves 10 will be realized. The first door leaf is preferably used first 10a operated and the second door leaf 10b follows the actuation a little later.

It would also be conceivable how this is done in the 5 and 6 shown is the linear guide (guide rail 22nd ) and the guide head 24 designed as a conventional drawer slide, with a static guide rail 22nd on the body 4th and one relative to the static guide rail 22nd movable guide rail 24 forms the guide head on which the door leaves 10 , e.g. via the push / pull rods 26th , are hinged. The gear 20a , especially the drawer slide 22nd , 24 , can have a closing aid so that when the door leaves are open 10 (see. 6 ) a gentle operation of the first door leaf 10a and overcoming a dead center is sufficient to open the door leaves 10 spring-assisted by the closing aid into the closed position (cf. 5 ) to pull. An example of such a closing aid is in 19th with the reference number 50 denotes and comprises a spring element 52 . The spring element 52 is designed as a spiral spring. However, other spring elements can also be used.

Furthermore, the drawer slide 22nd , 24 at least one damping element 48 have to dampen the door leaves towards the end of the opening movement and let them slide slowly into the open position. The damping element 48 can comprise a gas or oil pressure damper. An example of such a damping element 48 is in 20th shown. Of course, a damping element can also be provided in order to dampen the door leaves towards the end of the closing movement and to let them slide slowly into the closed position.

When the push / pull rods 26th for the first and second door leaf 10a , 10b different lengths can be chosen, and at different distances from the vertical axis 14th are attached, the door leaves 10a , 10b be opened to different degrees. It would be conceivable, for example, that a left door leaf 10b max. to 85 ° opens, while the right door leaf 10a opens up to max. 95 °. This can be an advantage in local conditions to prevent the left door leaf 10b hits against obstacles (e.g. radiators).

According to a second embodiment of the invention, which in the 7th and 8th is shown, it is proposed that the transmission 20b one on the body 4th of the closet 2 , especially on an upper wall of the body 4th , by means of a guide rail 22nd linearly guided guide head 24 having. The linear guide (rail 22nd ) of the guide head 24 runs preferably perpendicular to the surface extension of the door leaves 10 in their closed position (cf. 7th ). The transmission also includes 20b one on the guide head 24 around an axis of rotation 54 rotatably mounted rotary lever 56 with ring gear 58 . The axis of rotation 54 is in a center of the ring gear 58 arranged and runs parallel to the vertical axes 14th the door leaf 10 . The door leaves 10 are on one of the sprockets 58 opposite end of the respective rotary lever assigned to them 56 hinged. The ring gear 58 of the first door leaf 10a assigned rotary lever 56a stands with the ring gear 58 of the second door leaf 10b assigned rotary lever 56b engaged. The door leaves 10 can each directly (or via a linear guide) to the gear rim 58 opposite end of the respective rotary lever assigned to them 56 be articulated. Preferably the door leaves 10 but one at a fixed angle on the door leaves 10 attached guide arm 60 on that of the ring gear 58 opposite end of the respective rotary lever assigned to them 56 hinged. The angle is preferably 90 °, so that the guide arms 60 each perpendicular to the corresponding door leaf 10 stick out. The guide arms 60 of the first door leaf 10a and the second door leaf 10b can be at the same or at different angles on the door leaves 10 be attached.

In this exemplary embodiment, a user grips the first door leaf 10a the closed wing doors (cf. 7th ) on a handle section 28 and opens the door 10a . Via the first guide arm 60a the one on the first door wing 10a is attached, becomes the first rotary lever 56a into a rotation around its axis of rotation 54 (clockwise) offset. This rotation is done via the ring gear 58 of the first rotary lever 56a and the ring gear 58 of the second rotary lever 56b transferred to this so that it rotates around its axis of rotation 54 (counterclockwise). The guide head 24 on which the rotary lever 56 are rotatably mounted on its linear guide (guide rail 22nd ) can be moved. The rotation of the second rotary lever 56b is on the second guide arm 60b transferred to the second door leaf 10b is attached, and the second door leaf 10b opens automatically.

This rotation is done via the ring gear 58 of the first rotary lever 56a and the ring gear 58 of the second rotary lever 56b transferred to this so that it rotates around its axis of rotation 54 (clockwise). The guide head 24 on its linear guide (guide rail 22nd ) can be moved. The rotation of the second rotary lever 56b is on the second guide arm 60b transferred and the second door leaf 10b automatically closed. This embodiment ensures synchronous actuation of the door leaves 10 . However, if you turn the lever 56 selects different lengths and / or the guide arms 60 selects different lengths and / or the guide arms 60 at different angles with respect to the door leaves 10 attached, could be with the gearbox 20b an asynchronous actuation of the door leaves 10 will be realized.

A third embodiment of the invention is shown in FIGS 9 and 10 shown. The gear 10c shows each door leaf 10 one on the body 4th of the closet 2 , especially on the top wall of the body 4th , about an axis of rotation 62 rotatably mounted rotary lever 64 with ring gear 66 on. The axis of rotation 62 is in a center of the ring gear 66 arranged and runs parallel to the vertical axes 14th the door leaf 10 . The door leaves 10 are on one of the sprockets 66 opposite end of the respective rotary lever assigned to them 64 hinged. The ring gear 66 of the first door leaf 10a assigned rotary lever 64a stands with the ring gear 66 of the second door leaf 10b assigned rotary lever 64b engaged. It is conceivable that the door leaves 10 each directly (or via a linear guide) on the gear rim 66 opposite end of the respective rotary lever assigned to them 64 are hinged. The door leaves are advantageous 10 each with a push / pull rod 68 on that of the ring gear 66 opposite end of the respective rotary lever assigned to them 64 hinged.

The turning points of the push / pull rods 68 are with the reference symbols 70 or. 72 designated.

The rotation of the second rotary lever 64b is on a second push / pull rod 68b transferred to the second rotary lever 64b and the second door leaf 10b is hinged, and the second door leaf 10b opens automatically.

The user grips the first door leaf in a corresponding manner 10a the opened double doors (cf. 10 ) on the handle section 28 and closes the door 10a . Via the first push / pull rod 68a becomes the first rotary lever 64a into a rotation around its axis of rotation 62 offset (counterclockwise). This rotation is done via the ring gear 66 of the first rotary lever 64a and the ring gear 66 of the second rotary lever 64b transferred to this so that it rotates around its axis of rotation 62 (clockwise). The rotation of the second rotary lever 64b is on the second push / pull rod 68b transferred and the second door leaf 10b automatically closed. This embodiment ensures synchronous actuation of the door leaves 10 . However, if you turn the lever 64 selects different lengths and / or the push / pull rods 68 selects different lengths and / or the number of teeth 66 on the rotary levers 64 selects different and / or the deflection points 70 , 72 asymmetrical to the median plane 46 arranges, could with the transmission 20c an asynchronous actuation of the door leaves 10 will be realized.

According to a fourth embodiment of the invention, which is shown in the 11 and 12th shown has the transmission 20d per door leaf 10 one on the body 4th of the closet 2 , especially on the top wall of the body 4th , about an axis of rotation 74 rotatably mounted gear 76 on. The axis of rotation 74 runs parallel to the vertical axis 14th the door leaf 10 . The first door leaf 10a associated gear 76a stands with the second door leaf 10b associated gear 76b engaged. On the door leaves 10 is each a rack 78 is hinged when operating the door leaf 10 each with their teeth 80 on the corresponding door leaf 10 associated gear 76 unrolls. The turning points where the racks 78 on the door leaves 10 are hinged are indicated by the reference number 79 designated.

In this exemplary embodiment, a user grips the first door leaf 10a the closed wing doors (cf. 11 ) on the handle section 28 and opens the door 10a . The first rack slides 78a that is on the first door leaf 10a is hinged, with their teeth 80 about the first gear 76a and sets it in a rotary motion around its axis of rotation 74 (clockwise). The first rack 78a can be spring loaded on the outer circumference of the first gear 76a be pressed. This rotation is made possible by the meshing gears 76 on the second gear 76b transferred that in a rotary motion around its axis of rotation 74 (counterclockwise).

This is moved along its length, and the movement on the second door leaf 10b so that it is automatically closed. This embodiment ensures synchronous actuation of the door leaves 10 . But if you have the turning points 79 asymmetrical to the median plane 46 arranges and / or the number of teeth / diameter of the gears 76 Chooses differently, could with the gearbox 20d an asynchronous actuation of the door leaves 10 will be realized.

According to a fifth embodiment of the invention, which in the 13 and 14th shown has the transmission 20e one on the first door leaf 10a Guide arm fixed at a fixed angle 82 on. The second door wing 10b is via a push / pull rod 84 on the guide arm 82 hinged. The push / pull rod 84 is on the one hand in a turning point 86 on the second door leaf 10b and on the other hand in a turning point 88 on one of the first door leaves 10a opposite end of the guide arm 82 hinged. The angle between the guide arm 82 and first door leaf 10a is preferably 90 °, so that the guide arm 82 perpendicular to the first door leaf 10a protrudes, but can also be a different angle. The guide arm 82 is preferably at a distance from a hinge 12th over which the first door leaf 10a on the body 4th of the closet 2 is articulated, or to the corresponding vertical axis 14th on the first door leaf 10a attached. The push / pull rod 84 is preferably at a distance from a hinge 12th over which the second door leaf 10b on the body 4th of the closet 2 is articulated, or to the corresponding vertical axis 14th on the second door leaf 10b hinged.

To operate the wing doors, a user grabs the first door wing 10a the closed wing doors (cf. 13 ) on the handle section 28 and opens the door 10a . The guide arm 82 moves together with the first door leaf 10a , being the turning point 88 of the guide arm 82 on which the push / pull rod 84 is articulated on a circular path around the vertical axis 14th of the first door leaf 10a moved (counterclockwise). A pushing force acts on the push / pull rod 84 which is the thrust on the second door leaf 10b transfers to which the push / pull rod 84 is hinged so that the door leaf 10b opens automatically.

The user grips the first door leaf in a corresponding manner 10a the opened double doors (cf. 14th ) on the handle section 28 and closes the door 10a . The moves Guide arm 82 together with the first door leaf 10a , being the turning point 88 of the guide arm 82 on which the push / pull rod 84 is articulated on the circular path around the vertical axis 14th of the first door leaf 10a moved (clockwise). A tensile force acts on the push / pull rod 84 , which is the tensile force on the second door leaf 10b transmits so that the door leaf 10b closes automatically.

The guide arm 82 is roughly in the middle of the inside of the first door leaf 10a attached. The push / pull rod 84 is roughly in the middle of the inside of the second door leaf 10b hinged. This embodiment ensures synchronous actuation of the door leaves 10 . However, if you consider the length of the guide arm 82 and / or the push / pull rod 84 selects different than shown and / or the guide arm 82 elsewhere on the first door leaf 10a attached and / or the push / pull rod 84 at another point on the second door leaf 10b links, could with the gearbox 20e an asynchronous actuation of the door leaves 10 will be realized.

According to a sixth embodiment, which is in the 15th and 16 shown has the transmission 20f one on the body 4th of the closet 2 , especially on the top wall of the body 4th , about an axis of rotation 90 pivoted lever 92 on. The axis of rotation 90 runs parallel to the vertical axes 14th the door leaf 10 . The door leaves 10 are each at a turning point 94 on the reversing lever 92 hinged. The articulation can be direct or indirect, for example via push / pull rods 96 , respectively. The push / pull rods 96 are about turning points 98 on the door leaves 10 hinged. Preferably the axis of rotation 90 the same distance to the vertical axes 14th the door leaf 10 . The door leaves 10 are each at different turning points 94a , 94b on the reversing lever 92 hinged. The deflection points preferably have 94a , 94b In each case in a plane (for example the plane of the drawing), different distances to the axis of rotation are considered at least in one direction 90 of the reversing lever 92 on. In the example shown, the deflection points have 94a , 94b Different distances from the axis of rotation, viewed in the plane in two directions perpendicular to one another 90 of the reversing lever 92 on. In a first direction there is a distance a between the axis of rotation 90 and the turning point 94a greater than a distance b between the axis of rotation 90 and the turning point 94b . In a second direction running perpendicular to the first direction there is a distance a ′ between the axis of rotation 90 and the turning point 94a equals zero. A distance b 'between the axis of rotation 90 and the turning point 94b in the second direction is greater than the distance a '(= 0).

To operate the wing doors, a user grabs the first door wing 10a the closed wing doors (cf. 15th ) on the handle section 28 and opens the door 10a . This becomes the reversing lever 92 on which the first door leaf 10a e.g. via the first push / pull rod 96a is articulated in a rotary movement about the axis of rotation 90 (clockwise) offset. This turning movement creates an effect on the second door leaf 10b , the one on the rocker arm 92 e.g. via a second push / pull rod 96b is articulated, acting thrust that an automatic opening of the door leaf 10b causes.

The user grips the first door leaf in a corresponding manner 10a the opened double doors (cf. 16 ) on the handle section 28 and closes the door 10a . This becomes the reversing lever 92 into a rotary movement around the axis of rotation 90 offset (counterclockwise). This rotary movement generates an effect on the at least one second door leaf 10b acting tensile force that causes the door leaf to close automatically 10b causes.

In the example shown, the push / pull rods are 96 the same length and at the appropriate points on the door leaves 10 hinged (the distance between the hinges 12th and the turning points 98 is for both door leaves 10 equal). This embodiment ensures synchronous actuation of the door leaves 10 . However, if you consider the length of the push / pull rods 96 selects different lengths and / or the distances a, b, a ', b' between the axis of rotation 90 and the turning points 94 selects different than shown and / or the push / pull rods 96 in different places on the door leaves 10 links, could with the gearbox 20f an asynchronous actuation of the door leaves 10 will be realized.

According to a seventh embodiment, which is in the 17th and 18th is shown, has the axis of rotation 90 of the reversing lever 92 different distances to the vertical axes 14th the door leaf 10a , 10b on. In this case the door leaves 10 at the same turning point 100 on the reversing lever 92 be articulated. Also a linkage of the door leaves 10 at different deflection points of the reversing lever 92 would be conceivable (not shown). The door leaves 10 are preferably via push / pull rods 96 on the reversing lever 92 hinged. The push / pull rods 96 can have the same or different lengths. This embodiment ensures an asynchronous actuation of the door leaves 10 . The gear 20g but can also be designed so that the door leaves are actuated synchronously 10 causes.

The gear 20th the device according to the invention is preferably designed, the door leaves coupled to one another 10 after reaching a open position of the door leaves 10 to secure in this position so that they cannot leave this position by themselves. Securing the door leaves 10 in the open position is preferably carried out automatically after reaching the open position. This can be done, for example, by an on the transmission 20th in the closed position of the door leaves 10 effective spring load can be realized (see closing aid 50 in 19th ). This has the advantage that the door leaves open 10 cannot close again by themselves from the open position. If the closet 2 Has drawers, this prevents the inside of the door leaf 10 damaged by pulled out drawers. For closing the door leaves secured in the open position 10 the securing forces, for example the spring forces, simply have to be overcome.

The gear 20th the device according to the invention is preferably designed to be an actuating movement of the door leaves coupled to one another 10 from a closed position to an open position and / or vice versa, so that after overcoming a dead center at the beginning of the actuation movement, the remaining actuation movement is carried out automatically. Accordingly, the fitting for the cabinet 2 so a support element 102 on, which after overcoming a dead center an opening movement and / or a closing movement of the door leaves 10 supported. By coupling the door leaves 10 about the gearbox 20th it can be sufficient if the support element 102 only on one of the door leaves 10 works. The support element 102 can also be on the guide head 24 or on the reversing lever 92 act and be articulated on this, whereby the support movement on the push / pull rods 26th and on the door leaves 10 is transmitted.

A corresponding embodiment is shown in 21st to 23 shown. In the example shown, the support element is 102 with his from the guide head 24 remote end 104 on the body 4th of the closet 2 , preferably on a top wall of the cabinet 2 , hinged. In 21st (closed door leaves 10 ) is the support element 102 in a first extended position, and in 22nd (opened door leaves 10 ) it is in a second extended position. When the door leaves move 10 An intermediate position is reached between the open and the closed position (cf. 23 ), in which the dead center of the support element 102 is run through. In the example the support element is 102 designed as a compression spring. The one-way support element 102 promotes both the closing and opening movement of the door leaves 10 and pushes it into the closed or open position. A damping element, which can also be present, can dampen the closing and / or opening movement. The support element 102 can for example be designed as a spring element (for example spiral, fluid, oil, gas pressure or air spring). Instead of being a separate component (cf. 21-23 ) the support element can also be an integral part of the transmission 20th be (see closing aid 50 with spring element 52 in 19th ). Integral part of the support element 102 can be a damping element 48 be. Alternatively, the damping element 48 also an integral part of the guide head 24 be.

The gear 20th is preferably designed, an actuating movement of the door leaves coupled to one another 10 from a closed position to an open position and / or vice versa towards the end of the actuation movement. Accordingly, the fitting for the cabinet 2 i.e. a damping element (see damping element 48 in 20th and support element with integrated damping unit 50 in 19th ), which is an opening movement and / or a closing movement of the door leaf 10 at the end of the movement and so for a gentle, low-noise approach of the door leaves 10 ensures the open or closed position. By coupling the door leaves 10 about the gearbox 20th it can be sufficient if the damping element 48 only on one of the door leaves 10 works. The damping element 48 can, for example, be designed as a gas pressure or oil damper, which is an integral part of the transmission 20th is.

Finally, it is also conceivable that the transmission 20th having coupled to one another air, gas, oil or fluid cylinders to when one of the door leaves is actuated 10a ; 10b of the closet 2 the other door leaf 10b ; 10a forced to operate. The cylinders can be coupled to one another using flexible lines or rigid lines. The cylinders form a closed system with a defined amount of air, gas, oil or some other fluid that is released when the door leaves are operated 10 is moved back and forth between the piston chambers. A reduction in the volume of the piston chamber of one cylinder leads to an increase in the volume of the piston chamber of the other cylinder and, conversely, an increase in the volume of the piston chamber of one cylinder leads to a decrease in the volume of the piston chamber of the other cylinder. The consequence of a movement of one cylinder is a forced actuation of the other cylinder. The cylinder rods are hinged to the respective door leaves.

24 shows a further embodiment in which the transmission 20g also includes a deflection gear, which one on the first door leaf 10a acting pulling force or pushing force in a the at least one second door leaf 10b acting thrust or tensile force diverts. The gear 20g has one on the body 4th of the closet 2 , the chest of drawers or the container around an axis of rotation 90 pivoted lever 92 on. The axis of rotation 90 runs parallel to the vertical axes 14th the door leaf 10 . The door leaves 10 are each at a turning point 100 on the reversing lever 92 hinged. The axis of rotation 90 of the reversing lever 92 shows different distances to the vertical axes 14th the door leaf 10 on. The reversing lever 92 is a damping element 48 to dampen a closing and / or opening movement of the door leaves 10 , especially towards the end of the movement. The damping element 48 can, for example, be designed as a gas pressure, oil, fluid, air damper or any other type of damper.

In the example shown is the axis of rotation 90 not on the bell crank 92 arranged, but laterally offset to it. In particular, is on the reversing lever 92 a control arm 106 is attached to a fixed angle (> 0 ° ... 90 °), with the axis of rotation 90 on one of the bell crank 92 remote end of the control arm 106 is arranged.

In the example shown is the reversing lever 92 variable in length. In particular, the reversing lever 92 two lever elements which can be moved longitudinally relative to one another 92a , 92b on. Of course, the lever can 92 also more than two lever elements which are longitudinally displaceable relative to one another 92a , 92b exhibit. The damping element 48 can end with a first 48a on a first lever element 92a and with a second end 48b on another lever element 92b be attached. The axis of rotation is preferred 90 of the reversing lever 92 on one of the lever elements (via the control arm 106 on the first lever element 92a ) and are the deflection point or points 42 ; 94 ; 100 over which the door leaves 10 on the reversing lever 92 are articulated on another lever element 92b arranged. The lever elements 92a , 92b can be designed to be displaceable relative to one another via centrally or laterally arranged guide elements, for example guide rails, rollers or the like. Central guide elements can, for example, through a central, along a longitudinal extension of one of the lever elements 92a ; 92b formed guide slot and a longitudinally displaceable guide pin guided therein on another lever element 92b ; 92a be realized. Lateral guide elements can, for example, by means of lateral guide legs of two lever elements that can be displaced relative to one another 92a , 92b be realized, the guide legs of one of the lever elements 92a ; 92b with their outer surfaces on the inner surfaces of the guide legs of the other lever element 92b ; 92a can slide along. Sliding elements, for example balls of a ball bearing, rollers of a roller bearing, sliding coatings (for example made of plastic, in particular polytetrafluoroethylene (PTFE)), can be arranged between interacting guide elements.

A synchronous actuation of the two door leaves 10a , 10b to enable, acts the reversing lever 92 preferably together with a guide mechanism, so that the reversing lever 92 when running through a closing or opening movement between a closed and an open position of the door leaves 10 Goes through phases of different lengths. The turning points pass through it 42 ; 94 ; 100 preferably a linear movement that is perpendicular to the surface extension of the door leaf 10 runs in its closed position. The path of linear motion is in 24 with the reference number 108 designated.

The guide mechanism with which the bell crank 92 works together to make linear motion 108 the turning points 42 ; 94 ; 100 over which the door leaves 10 on the reversing lever 92 are articulated to realize can be designed differently. In principle, for reasons of cost and stability, simple guide mechanisms are to be preferred, but more complex guide mechanisms are also conceivable. For example, in 26th suggested that the guide mechanism be a curve guide 110 includes. There is at least one of the lever elements 92b of the reversing lever 92 , preferably that lever element 92b at which the turning points 42 ; 94 ; 100 over which the door leaves 10 on the reversing lever 92 are articulated, are arranged, in a non-rectilinear, preferably arcuate guide element 112 guided. The guided lever element 92b the door leaf is activated during an actuation movement (ie opening or closing movement) 10 such relative to the at least one other lever element 92a led to the turning points 42 ; 94 ; 100 a linear movement 108 run perpendicular to the surface extension of the door leaf 10 runs in its closed position.

It would also be conceivable that the guide mechanism is a lever guide 114 includes, as exemplified in the 27-29 is shown. You can use several levers 116 , 118 that put together the lever guide 114 form on the reversing lever 92 be hinged so that the deflection points 42 ; 94 ; 100 when the door is operated (opened or closed) 10 a linear movement 108 run perpendicular to the surface extension of the door leaf 10 runs in its closed position. In this case it is the reversing lever 92 not directly on the body 4th of the cabinet or similar, but indirectly via at least one of the levers 116 , 118 . The levers 116 , 118 the lever guide 114 include, for example, a control arm 116 and a balance arm 118 . Both arms 116 , 118 are rotatable at a distance from each other on the reversing lever 92 hinged. In particular are the arms 116 , 118 on the lever element 92a hinged, that is not the deflection points 42 ; 94 ; 100 having. If the bell crank 92 is not designed to be variable in length, the arms can 116 , 118 however, it may very well be articulated on the same (single) lever element that also has the deflection points 42 ; 94 ; 100 having. With her the bell crank 92 opposite end are the arms 116 , 118 on the body 4th of the cabinet or similar, especially on the ceiling or the floor of the body 4th , also rotatably attached. Through the lever guide 114 becomes the fulcrum 90 of the reversing lever 92 Are defined. The fulcrum 90 is now no longer at a defined point, but moves relative to the body 4th while the door leaves are operated 10 .

Finally, it would also be conceivable for the guide mechanism to be a linear guide, for example in the form of a guide rail 22nd , includes (cf. 1-8 ), which is perpendicular to the surface extension of the door leaf 10 runs in its closed position. In particular the lever element 92b at which the turning points 42 ; 94 ; 100 the door leaf 10 are arranged, is guided in the linear guide, so that the deflection points 42 ; 94 ; 100 when the door is operated (opened or closed) 10 the desired linear movement 108 To run. So can for example. On the reversing lever 92 a guide head 24 be formed, which is guided in the linear guide and at which the deflection points 42 ; 94 ; 100 are trained.

Of course, in the examples of the 1-8 the reversing lever described above 92 including damping element 48 on the guide head 24 or hinged at another point (cf. 1 and 4th ). In the example of 9 and 10 could the reversing lever described above 92 including damping element 48 for example on one of the rotary levers 64 or hinged at another point. In the example of 11 and 12th could the reversing lever described above 92 including damping element 48 for example on one of the racks 78 or hinged at another point. In the example of 13 and 14th could the reversing lever described above 92 including damping element 48 for example on the guide arm 82 , the push / pull rod 84 or hinged at another point.

Take the example of 24 and 25th a corresponding example is in the 15th and 16 shown, the reversing lever 92 there is not variable in length and is not straight. Also such a lever 92 can in the manner according to the invention with a damping element 48 work together. The same applies to the example of 17th and 18th with a straight lever, not variable in length 92 . With the respective, the reversing lever 92 opposite end 48a is the damping element 48 on the body 4th hinged.

It is conceivable that the transmission has a support element 102 is assigned, which is an actuation movement of the door leaves coupled to one another 10 from a closed position to an open position and / or vice versa, so that the remaining actuation movement is carried out automatically after a dead center has been overcome. The support element 102 can be used as a separate part (cf. 21st to 23 ) or as an integral part of the damping element 48 be trained.

The support element 102 is preferably designed as a compression spring element. When the damping element 48 For example, if it is designed as a gas pressure, oil, fluid, air damper or the like, it can also function as the support element at the same time 102 realize. In this way, a damping and a support function can be realized by a single element. The support element 102 can also be the door leaf 10 hold in their closed and / or open position.

To the door leaves 10 Opening from the closed position becomes a door leaf 10a initially against the force of the damper / support element 48 open. By coupling the door leaves 10 by means of the gearbox 20th becomes the second door leaf 10b forced to open. After overcoming a dead center, for example at an opening angle of the door leaves 10 of about 45 °, the pressure force of the damper / support element acts 48 supporting on the reversing lever 92 and thus on the door leaves 10 and ensures that the door leaves continue to move 10 into the open position or supports the opening movement. Due to the pressure that continues to act, the door leaves 10 through the damper / support element 48 held in the open position. For closing the door leaves 10 becomes one of the door leaves 10a initially against the force of the damper / support element 48 moved towards the closed position. By coupling the door leaves 10 by means of the gearbox 20th becomes the second door leaf 10b forcibly closed with. After the dead center has been overcome, the pressure force of the damper / support element acts 48 supporting on the reversing lever 92 and thus on the door leaves 10 and ensures that the door leaves continue to move 10 into the closed position or supports the closing movement. Due to the pressure that continues to act, the door leaves 10 through the damper / support element 48 held in the closed position.
