1. Field of the Invention The present invention relates to a swinging/sliding door for passenger vehicles, wherein the door includes at least one door leaf which is mounted so as to be slidable in its longitudinal direction on a guide element, wherein the guide element is a part of a four-bar mechanism or linkage and is movable transversely of the plane of the door leaf, and wherein the drive force of a door driving device acts on the door leaf essentially in the direction of the guide element and the reaction force of the drive device exerts a torque on a rotary member which is provided between the guide element and the door frame and which moves the guide element transversely of the door leaf plane.
1. Field of the Invention The present invention relates to a swinging/sliding door for passenger vehicles, wherein the door includes at least one door leaf which is mounted so as to be slidable in its longitudinal direction on a guide element, wherein the guide element is a part of a four-bar mechanism or linkage and is movable transversely of the plane of the door leaf, and wherein the drive force of a door driving device acts on the door leaf essentially in the direction of the guide element and the reaction force of the drive device exerts a torque on a rotary member which is provided between the guide element and the door frame and which moves the guide element transversely of the door leaf plane.
2. Description of the Related Art A swinging/sliding door of the above-described type is known from EP 0 536 528 Bl which corresponds to DE 41 33 179 Al. In this known device, the long:itudinal movement of the door leaf is coordinated with the transverse movement of the guide element by a guide rail which is fixed:Ly connected to the door frame and which is engaged by a guide piece which is fixedly connected to CA 0223~877 1998-04-27 the door leaf. The reaction moment of the drive acts on a part which is called a "spreading element" which, in turn, is supported on a support member fixedly attached to the door frame.
This known construction is difficult and cumbersome with respect to its assembly and adjustment because of the many supports, guides, fastenings, and, thus, reference points between the actual door leaf drive and the corresponding guide mechanism, on the one hand, and the parts fixed to the door frame, on the other hand.
It must also be taken into consideration that, in addition to the parts mentioned above, a door post pipe must be provided for each door leaf and must be coordinated with respect to its rotation to the drive in order to be able to guide the door leaf in its upper portion as well as in its lower portion, because the part called the guide element in the known solution actually has a pure support function and the guidance of the door leaf is effected exclusively by the door post pipe, its pivot arms and corresponding rails in the door leaf.
In this known solution, there is the additional problem that, because of the specific selection of the four-bar mechanism, the door can be c,pened even in the closed state with CA 0223~877 1998-04-27 currentless drive if appropriate forces act on the door leaf;
this may occur, for example, as a result of acts of vandals, but also as a result of normal vibrations during travel or by older or infirm persons who rest against the door leaf, which must be absolutely prevented for safety reasons. For this reason, this known solution provides for a special locking mechanism which requires an additional fastening point at the door frame which must be precisely adjusted. All the above factors apparently contribute to the fact that this known swinging/sliding door has not yet been used in practic:e.
CA 0223~877 1998-04-27 SlJMM~RY OF TEIE lNVl!.Nl lON
Therefore, it is the primary object of the present invention to provide a swinging/sliding door for passenger vehicles which avoids the disadvantages of the known solution and can be easily and quickly assembled and, i.n accordance with a preferred embodiment, is secured against unintentional opening even without a locking mechanism.
In accordance with the present invention, the four-bar mechanism or linkage is a parallelogram mechanism or linkage wherein the sides of the mechanism constructed as pivot plates and rotatably mounted on the chassis and the drive extending essentially parallel to the guide element and the actuating arms for pivoting the door post pipe are supported on the pivot plates, and wherein the coordination of the longitudinal movement of the door leaf with the transverse movement of the guide element is effected by a yok:e which is pivotable about an axis fixedly attached to the chas;sis, wherein, on the one hand, the yoke is engaged by a guide means fixedly connected to the door leaf and, on the other hand, the yoke engages with a guide pin in a guide slot of the guide element.
CA 0223~877 1998-04-27 As a result of the configuration according to the present invention, the entire mechanism for moving the swinging/sliding door is connected to the chassis only through the two pivot plate axes and the axis of the pivot yoke. In accordance with further developments of the invention, an abutment is provided for a spring acting on the pivot yoke and a stop is provided for the rotary movement of the pivot plates in the closing direction.
However, all of these connections to the chassis can be provided on a single section or an assembly plate, so that the assembly of the completely preassembled and pread~usted drive in the chassis can take place by the asse~ly of a single part, namely, the support section or the support plate.
By omitting the guide rail fixedly attached to the chassis, a significant reduction of the components to be provided and, thus, a significantly easier access for maintenance and inspection purposes is possible in the area of the chassis above the door head or lintel where always only little space is available.

Fig. 2 is a schematic t;op view of the swinging/sliding door of Fig. 1 shown in the opened state;

CA 0223~877 1998-04-27 DESCRIPTION OF THE PREFERRED EMBODIMENTS
Fig. 1 of the drawing shows a swinging/sliding door with two door~leaves 1, 2 and door drive mechanism which in its totality is denoted by reference numeral 3. The door drive mechanism are considered to be all those components which are not rigidly and fixedly connected to the door leaf, nor rigidly and fixedly connected to the chassis 4. Thus, all components which are movably hinged to the door ]eaf and/or the chassis are components of the door/drive mechanism..
As is apparent from Figs. 1 and 2, the door leaves 1, 2 slide on a telescopic guide element 5 which during the opening movement of the door carries out a movement perpendicularly of the plane of the door leaf. This transverse door movement is facilitated by pivoting of a parallelogram mechanism which is composed, on the one hand, of the guide element 5 and, on the other hand, of two pivot plates 6, and finally, of chassis components located between the axes 7 of rotation of the pivot plates 6.
The actual drive which extends essentially parallel to the guide element 5 is also supported on the pivot plate 6, so that the drive also ~orms with the pivot axes 7 a parallelogram CA 0223~877 1998-04-27 mechanism relative to the chassis and carries out during the opening movement a translatory pivoting movement about these axes of rotation.
In the illustrated embodiment, the drive 29 is composed of an electric motor 8, a spindle 9 and a master carriage 10 which is guided on rollers and acls on the door leaf 2 through a drive arm 11. The force introduction is effected onto an arm 12 which, contrary to being rotatable or pivotable, is fixedly and rigidly arranged with the door leaf 2.
As is apparent especially from Fig. 3, the arm 12 supports a pin or roller 13 which comes to rest in the recess between the prongs 14 of a pivot yoke 15. The pivot yoke 15 is pivotable about an axis 16 fixedly arranged on the chassis and, in turn, supports a guide finger 17 which engages in a slot 18 of a guide plate 19 which is fixedly and rigidly connected to the guide element 5.
When the door drive 29 is activated for opening, the motor 8 moves the spindle 9 and the master carriage 10 applies pressure to the drive arm 11 and seeks to push the door leaf 2 open in this manner. This is prevented by the guide roller 13 which is attached fixedly to the door leaf and engages in the pivot yoke CA 0223~877 1998-04-27 15, so that the reaction force of the drive causes the entire drive 29 to be pushed to the left as seen in the drawing and relative to the chassis and is rotated in a clockwise direction about the pivot axes 7.
Since the guide element 5 is also pivoted by this pivoting movement of the pivot plates 6, the guide element 5 is moved outwardly and its longitudinal slot 18 takes along the guide finger 17 of the pivot yoke 15 and, thus, effects a rotation of the pivot yoke 15, so that, after the guide element 5 has been completely moved out, the guide roller 13 of the door leaf 2 is moved out of the range of the prongs 14 of the yoke 15 which now has been rotated, so that driving is now possible and the door leaf 2 can be pushed by drive arm 11 in opening direction along the guide element 5.
The coordination of the movement of the second door leaf 1 is preferably effected by an endless rope or toothed belt or the like, wherein the door leaf 1 is attached to one of the portions and the door leaf 2 is attached to the other portion of the rope or toothed belt, so that it is ensured that the two door leaves are always positioned symmetrically relative to the plane 20 of symmetry.
CA 0223~877 1998-04-27 In the illustrated, preferred embodiment, the guide yoke 15 is subjected to load by a spring mechanism 21 in such a way that the yoke 15 is urged by the effect of this spring mechanism 21 always into one of the two possible end positions. In this manner, it is ensured that when the door is open vibrations or the like do not cause the yoke to leave the position illustrated in Fig. 4, wherein it is nec:essary to maintain this position so that the guide pin 13 of the door leaf 2 once again is moved into the region of the prongs 14 when the door leaf 2 is being closed and a proper closing of the entire door is possible.
In the situation of the yoke mechanism illustrated in Fig. 3 and corresponding to the closed position of the door, the spring mechanism 21 ensures that the closed position is maintained, however, as to be explained further below, this is effected primarily and essentially in a different manner, so that it is also possible to provide instead of the spring mechanism 21 a torsion spring in the area of the axis 16 of the yoke 15, wherein the axis 16 is fixed relative to the chassis, and wherein the torsion spring urges the yoke 15 into the position corresponding to the open position illustrated in Fig. 4.
In accordance with a preferred embodiment of the present invention, the door is guided in the bottom region and is CA 0223~877 1998-04-27 reliably kept closed even when the drive is without power in the manner described below and illustrated in Fig. 1. In addition to the structural components a]ready mentioned above, connected to the pivot plates 6 are also actuating arms 22 which act on adjusting arms 24 non-rotatably mounted on the door post pipes 23. When the door is openecl, and, thus, the pivot plates 6 are turned, the door post pipes 23 are also rotated. These door post pipes 23 support in the bott;om region of the chassis pivot arms 25 which at their free ends engage by means of the rollers 26 or the like into guides 27 of t:he door leaves 1,2 and guide and support these door leaves in the lower region.
As can be seen in Fig. 1, it is advantageously provided that, in the closed position of the door, the actuating arms 22 are located relative to the pivot axes 7 on that side which when a pressure is exerted on the door leaves 1, 2 exerts a torque on the pivot plates 6 so as to push the pivot plates out, so that the pivot plates 6 are also subjected to a load in the direction of a closing movement. As is apparent in the illustrated example, this is achieved by a dead center situation or an over-dead-center situation in which, during the final closing movement, the actuating arms 22 are moved past the pivot axis 7.
CA 0223~877 1998-04-27 As already known in the art, this feature makes it necessary to provide an emergency actuating device which, in accordance with the present invention, either acts on the drive or on the pivot plates 6 in order to achieve an opening movement and, thus, facilitates an opening of the door even when the motor 8 is without current.
In accordance with a preferred embodiment, not shown, the achievement of the over-dead-center-location is facilitated by a spring which acts on the door post pipe or the pivot plate or another structural component or between two structural components of the door drive in the closing direction. This is particularly advantageous for the emergency operation when the drive has failed.
The present invention is not limited to the illustrated embodiment. Rather, the invention can be modified in various ways. For example, it is possible to use a different linear motor instead of the spindle drive or to change the situation at the pivot yoke by a kinematic reversal, wherein, for example, a pin, mandrel, finger or the like is provided connected to the guide element 5 and the yoke 15 is provided with a correspondingly shaped slot-like guide.
CA 0223~877 1998-04-27 In the illustrated embodiment, the drive arm 11 or its point engagement with the door arm 12 is selected in such a way that during the opening and closing movements, the point of engagement deviates as little as possible on both sides from the direction of the linear drive. In special assembly situations, it is of course conceivable to place the point of engagement more closely toward the door leaf 2 or further away from the door leaf 2, so that t:he arm 11 is always located only on one side of the drive direct:ion. It is in special cases also conceivable to connect the drive arm 11 non-rotatably to the master carriage 10 and to provide a slot-like guide in the door arm 12 along which the point of engagement of the clrive arm 11 moves during the opening and closing movements.
Ilhe figures of the drawing further show that the end of the closing movement is adjustably predetermined by a stop 28;
however, this stop does not have to be arranged fixed to the chassis as in the illustrated embodiment, but the stop can also be replaced by an adjustable rotation limiting means between the drive 29 and the pivot plate 16 or between the guide element 5 and the pivot plate 6 or other components which are movable relative to each other during the opening and closing movements.
CA 0223~877 1998-04-27 ~ s is readily apparent from Figs. 1 and 2, all components which are fixed to the chassis and interact with door mechanism 3 can be easily provided on a slender assembly plate which requires little space or on an assembly section, so that finally only this assembly section or assembly plate has to be connected to the chassi.s to mount the entire mechanism 3. In that case, the actuat:ing arms 22 which effect the connection to the door post pipe 23 are preferably const:ructed so as to be adjustable in their length, so that any tolerances between the position of the door post pipes and the enti.re drive mechanism 3 are compensated.
~ hile specific embodiments of the invention have been shown and described in detail to i.llustrate the inventive principles, it will be understood that t.he invention may be embodied otherwise without departing from such principles.
This known construction is difficult and cumbersome with respect to its assembly and adjustment because of the many supports, guides, fastenings, and, thus, reference points between the actual door leaf drive and the corresponding guide mechanism, on the one hand, and the parts fixed to the door frame, on the other hand.
It must also be taken into consideration that, in addition to the parts mentioned above, a door post pipe must be provided for each door leaf and must be coordinated with respect to its rotation to the drive in order to be able to guide the door leaf in its upper portion as well as in its lower portion, because the part called the guide element in the known solution actually has a pure support function and the guidance of the door leaf is effected exclusively by the door post pipe, its pivot arms and corresponding rails in the door leaf.
In this known solution, there is the additional problem that, because of the specific selection of the four-bar mechanism, the door can be c,pened even in the closed state with CA 0223~877 1998-04-27 currentless drive if appropriate forces act on the door leaf;
this may occur, for example, as a result of acts of vandals, but also as a result of normal vibrations during travel or by older or infirm persons who rest against the door leaf, which must be absolutely prevented for safety reasons. For this reason, this known solution provides for a special locking mechanism which requires an additional fastening point at the door frame which must be precisely adjusted. All the above factors apparently contribute to the fact that this known swinging/sliding door has not yet been used in practic:e.

Therefore, it is the primary object of the present invention to provide a swinging/sliding door for passenger vehicles which avoids the disadvantages of the known solution and can be easily and quickly assembled and, i.n accordance with a preferred embodiment, is secured against unintentional opening even without a locking mechanism.
In accordance with the present invention, the four-bar mechanism or linkage is a parallelogram mechanism or linkage wherein the sides of the mechanism constructed as pivot plates and rotatably mounted on the chassis and the drive extending essentially parallel to the guide element and the actuating arms for pivoting the door post pipe are supported on the pivot plates, and wherein the coordination of the longitudinal movement of the door leaf with the transverse movement of the guide element is effected by a yok:e which is pivotable about an axis fixedly attached to the chas;sis, wherein, on the one hand, the yoke is engaged by a guide means fixedly connected to the door leaf and, on the other hand, the yoke engages with a guide pin in a guide slot of the guide element.

CA 0223~877 1998-04-27 DESCRIPTION OF THE PREFERRED EMBODIMENTS
Fig. 1 of the drawing shows a swinging/sliding door with two door~leaves 1, 2 and door drive mechanism which in its totality is denoted by reference numeral 3. The door drive mechanism are considered to be all those components which are not rigidly and fixedly connected to the door leaf, nor rigidly and fixedly connected to the chassis 4. Thus, all components which are movably hinged to the door ]eaf and/or the chassis are components of the door/drive mechanism..
As is apparent from Figs. 1 and 2, the door leaves 1, 2 slide on a telescopic guide element 5 which during the opening movement of the door carries out a movement perpendicularly of the plane of the door leaf. This transverse door movement is facilitated by pivoting of a parallelogram mechanism which is composed, on the one hand, of the guide element 5 and, on the other hand, of two pivot plates 6, and finally, of chassis components located between the axes 7 of rotation of the pivot plates 6.
The actual drive which extends essentially parallel to the guide element 5 is also supported on the pivot plate 6, so that the drive also ~orms with the pivot axes 7 a parallelogram CA 0223~877 1998-04-27 mechanism relative to the chassis and carries out during the opening movement a translatory pivoting movement about these axes of rotation.
In the illustrated embodiment, the drive 29 is composed of an electric motor 8, a spindle 9 and a master carriage 10 which is guided on rollers and acls on the door leaf 2 through a drive arm 11. The force introduction is effected onto an arm 12 which, contrary to being rotatable or pivotable, is fixedly and rigidly arranged with the door leaf 2.
As is apparent especially from Fig. 3, the arm 12 supports a pin or roller 13 which comes to rest in the recess between the prongs 14 of a pivot yoke 15. The pivot yoke 15 is pivotable about an axis 16 fixedly arranged on the chassis and, in turn, supports a guide finger 17 which engages in a slot 18 of a guide plate 19 which is fixedly and rigidly connected to the guide element 5.
When the door drive 29 is activated for opening, the motor 8 moves the spindle 9 and the master carriage 10 applies pressure to the drive arm 11 and seeks to push the door leaf 2 open in this manner. This is prevented by the guide roller 13 which is attached fixedly to the door leaf and engages in the pivot yoke CA 0223~877 1998-04-27 15, so that the reaction force of the drive causes the entire drive 29 to be pushed to the left as seen in the drawing and relative to the chassis and is rotated in a clockwise direction about the pivot axes 7.
Since the guide element 5 is also pivoted by this pivoting movement of the pivot plates 6, the guide element 5 is moved outwardly and its longitudinal slot 18 takes along the guide finger 17 of the pivot yoke 15 and, thus, effects a rotation of the pivot yoke 15, so that, after the guide element 5 has been completely moved out, the guide roller 13 of the door leaf 2 is moved out of the range of the prongs 14 of the yoke 15 which now has been rotated, so that driving is now possible and the door leaf 2 can be pushed by drive arm 11 in opening direction along the guide element 5.
The coordination of the movement of the second door leaf 1 is preferably effected by an endless rope or toothed belt or the like, wherein the door leaf 1 is attached to one of the portions and the door leaf 2 is attached to the other portion of the rope or toothed belt, so that it is ensured that the two door leaves are always positioned symmetrically relative to the plane 20 of symmetry.
CA 0223~877 1998-04-27 In the illustrated, preferred embodiment, the guide yoke 15 is subjected to load by a spring mechanism 21 in such a way that the yoke 15 is urged by the effect of this spring mechanism 21 always into one of the two possible end positions. In this manner, it is ensured that when the door is open vibrations or the like do not cause the yoke to leave the position illustrated in Fig. 4, wherein it is nec:essary to maintain this position so that the guide pin 13 of the door leaf 2 once again is moved into the region of the prongs 14 when the door leaf 2 is being closed and a proper closing of the entire door is possible.
In the situation of the yoke mechanism illustrated in Fig. 3 and corresponding to the closed position of the door, the spring mechanism 21 ensures that the closed position is maintained, however, as to be explained further below, this is effected primarily and essentially in a different manner, so that it is also possible to provide instead of the spring mechanism 21 a torsion spring in the area of the axis 16 of the yoke 15, wherein the axis 16 is fixed relative to the chassis, and wherein the torsion spring urges the yoke 15 into the position corresponding to the open position illustrated in Fig. 4.
In accordance with a preferred embodiment of the present invention, the door is guided in the bottom region and is CA 0223~877 1998-04-27 reliably kept closed even when the drive is without power in the manner described below and illustrated in Fig. 1. In addition to the structural components a]ready mentioned above, connected to the pivot plates 6 are also actuating arms 22 which act on adjusting arms 24 non-rotatably mounted on the door post pipes 23. When the door is openecl, and, thus, the pivot plates 6 are turned, the door post pipes 23 are also rotated. These door post pipes 23 support in the bott;om region of the chassis pivot arms 25 which at their free ends engage by means of the rollers 26 or the like into guides 27 of t:he door leaves 1,2 and guide and support these door leaves in the lower region.
As can be seen in Fig. 1, it is advantageously provided that, in the closed position of the door, the actuating arms 22 are located relative to the pivot axes 7 on that side which when a pressure is exerted on the door leaves 1, 2 exerts a torque on the pivot plates 6 so as to push the pivot plates out, so that the pivot plates 6 are also subjected to a load in the direction of a closing movement. As is apparent in the illustrated example, this is achieved by a dead center situation or an over-dead-center situation in which, during the final closing movement, the actuating arms 22 are moved past the pivot axis 7.
CA 0223~877 1998-04-27 As already known in the art, this feature makes it necessary to provide an emergency actuating device which, in accordance with the present invention, either acts on the drive or on the pivot plates 6 in order to achieve an opening movement and, thus, facilitates an opening of the door even when the motor 8 is without current.
In accordance with a preferred embodiment, not shown, the achievement of the over-dead-center-location is facilitated by a spring which acts on the door post pipe or the pivot plate or another structural component or between two structural components of the door drive in the closing direction. This is particularly advantageous for the emergency operation when the drive has failed.
The present invention is not limited to the illustrated embodiment. Rather, the invention can be modified in various ways. For example, it is possible to use a different linear motor instead of the spindle drive or to change the situation at the pivot yoke by a kinematic reversal, wherein, for example, a pin, mandrel, finger or the like is provided connected to the guide element 5 and the yoke 15 is provided with a correspondingly shaped slot-like guide.
CA 0223~877 1998-04-27 In the illustrated embodiment, the drive arm 11 or its point engagement with the door arm 12 is selected in such a way that during the opening and closing movements, the point of engagement deviates as little as possible on both sides from the direction of the linear drive. In special assembly situations, it is of course conceivable to place the point of engagement more closely toward the door leaf 2 or further away from the door leaf 2, so that t:he arm 11 is always located only on one side of the drive direct:ion. It is in special cases also conceivable to connect the drive arm 11 non-rotatably to the master carriage 10 and to provide a slot-like guide in the door arm 12 along which the point of engagement of the clrive arm 11 moves during the opening and closing movements.
Ilhe figures of the drawing further show that the end of the closing movement is adjustably predetermined by a stop 28;
however, this stop does not have to be arranged fixed to the chassis as in the illustrated embodiment, but the stop can also be replaced by an adjustable rotation limiting means between the drive 29 and the pivot plate 16 or between the guide element 5 and the pivot plate 6 or other components which are movable relative to each other during the opening and closing movements.
CA 0223~877 1998-04-27 ~ s is readily apparent from Figs. 1 and 2, all components which are fixed to the chassis and interact with door mechanism 3 can be easily provided on a slender assembly plate which requires little space or on an assembly section, so that finally only this assembly section or assembly plate has to be connected to the chassi.s to mount the entire mechanism 3. In that case, the actuat:ing arms 22 which effect the connection to the door post pipe 23 are preferably const:ructed so as to be adjustable in their length, so that any tolerances between the position of the door post pipes and the enti.re drive mechanism 3 are compensated.
