Abstract

The door has at least one panel (1,2) displaceable longitudinally on a guide component (5), which is movable as part of link rectangle crossways to its plane. The driven force of a door drive member (29) engages on the door panel (2) at least in the direction of the guide component. The reaction force of the drive device moves the guide component crossways to the plane of the door panel. The link rectangle is a link parallelogram. On arms formed as pivot plates (6) rotatably located on the vehicle bodywork, the drive (29) running parallel to the guide component and the operating arms (22) for pivoting the door beam tube (23) are located. At least one spring (23) engages preferably on the door beam tube or the pivot plates (6) and impels the door mechanism (3) into the closed position.

Description

The invention relates to a pivoting sliding door for vehicles for the transportation of passengers at least one door leaf slidable in its longitudinal direction on a guide element which is transverse as part of a quadrilateral joint is movable to the level of the door leaf at which the Downforce of a door drive device on the door leaf in the essentially attacks in the direction of the guide element and in which the reaction force of the drive device one provided between the guide member and the door frame Turned part exerts a torque through which the Guide element is moved transversely to the door leaf level.

Such a pivoting sliding door is known from EP 0 536 528 B1, according to DE 41 33 179 A1, known. With the known Device is the longitudinal movement of the door leaf the transverse movement of the guide element by one with the Door frame coordinated fixed guide rail, in which is a guide piece firmly connected to the door leaf intervenes. The drive's reaction torque acts a part called "expansion element", which in turn is supported in a support part fixed to the door frame.

These multiple supports, guides, fastenings and thus references between the actual door leaf drive and the associated guide mechanism on the one hand and door frame-fixed parts on the other hand make the previously known Construction in their installation and adjustment uncomfortable and expensive.

It should not be forgotten that in addition to the parts mentioned for each door leaf a door tube provided and with its twist with the drive must be coordinated to both the door leaf lead in its upper as well as in its lower area to be able to, since the part called the guide element in the previously known solution actually has a pure supporting function and the guidance of the door leaf exclusively through the Door tube, its swivel arms and associated rails in the Door leaf is done.

The previously known solution results from the special one Choice of the quadrangle still the problem that the Door closed even when the drive is de-energized can be opened when appropriate forces on the Door leaf act, which is caused, for example, by vandalism, but also due to normal vibrations while driving or by elderly or frail persons who are on the Support door leaf, can be done, but for security reasons is to be avoided at all costs. Because of this, looks the known solution a special locking mechanism before that another one to be precisely adjusted Requires attachment point on the door frame. Alles this probably contributes to the fact that the known pivoting sliding door have not yet been used in practice is.

The invention aims at the disadvantages of the known Avoiding the solution and creating a sliding sliding door, which are easy and quick to assemble and adjust is and in a preferred embodiment also without Locking mechanism against accidental opening is secured.

According to the invention it is provided that the four-bar linkage is a joint parallelogram, with on the car body rotatably mounted, designed as swivel plates Legs also essentially parallel to the guide element running drive and operating arms for the pivoting of the door tube are stored and that the coordination of the longitudinal movement of the door leaf with the Transverse movement of the guide element by one Carriage-fixed axle swiveling fork takes place in the on the one hand a guide means firmly connected to the door leaf engages and the other with a guide pin in a guide slot of the guide element intervenes.

This way the entire movement mechanism for the swivel sliding door only via the two swivel plate axes and the axis of the swivel fork with the body connected, one embodiment of the invention Abutment for a spring acting on the swivel fork and a stop for the rotary movement of the swivel plates comes in the closing direction, with all these connections to the Car body but on a single profile or a mounting plate can be provided so that the assembly of the completely pre-assembled and preset drive in the Car body by assembling a single part, namely of the support profile or the support plate can take place.

By eliminating the carriage rail fixed to the box body you get in the space that is always very limited Area of the car body above the lintel a significant reduction in the components to be provided and thus significantly easier access to maintenance and inspection purposes.

2 shows the pivoting sliding door of FIG. 1 in the open state,

3 shows the coordination mechanism according to the invention with the door and closed

Fig. 4 shows the mechanism of Fig. 3 in the open state of the door.

In Fig. 1 is a pivoting sliding door with two door leaves 1, 2 and a door drive mechanism designated overall by 3 shown. Be under door drive mechanism understood all the components that are neither rigid nor rigid with the door leaf still firm and rigid with the car body 4 are connected. Components that move on the door leaf and / or are hinged to the car body, are part of the door drive mechanism.

The door leaves 1, 2 slide, as from the cohesion of the 1 and 2 can be seen on a telescopic Guide element 5, which in the course of the opening movement of the Door moves normally to the level of the door leaves. This transverse movement is caused by the pivoting of a joint parallelogram, on the one hand consists of the guide element 5, on the other hand from two Swivel plates 6 and finally from between Axes of rotation 7 of the swivel plates 6 lying car body parts.

The actual drive is also on the swivel plates 6, running essentially parallel to the guide element 5, stored so that he with the pivot axes 7 a Joint parallelogram forms with respect to the car body and a (translational) pivoting in the course of the opening movement around these axes of rotation.

In the exemplary embodiment shown there is the drive 29 from an electric motor 8, a spindle 9 and one Roll guided mother car 10, which has a drive arm 11 attacks on door leaf 2. The force is applied on one with the door leaf 2 fixed and rigid (in contrast to rotatable or pivotable) arranged arm 12.

The arm 12 carries, as can be seen particularly from FIG. 3, a pin or a roller 13 which is in the recess to lie between the tines 14 of a pivot fork 15 is coming. The swivel fork 15 is fixed to a car body Axis 16 swivels and in turn carries a guide finger 17, which in a slot 18 of a guide plate 19th engages with the guide element 5 firmly and rigidly connected is.

If the door drive 29 is now activated to open, it sets the motor 8, the spindle 9 in motion and the mother carriage 10 loads the drive arm 11 under pressure and tries so to defer the door leaf 2. This is through the Guide roller 13, which is arranged fixed to the door leaf and which engages in the pivot fork 15 prevents, so that the entire drive due to the reaction force of the drive 29 with respect to the car body (seen in the drawing) pushed to the left and around the pivot axes 7 in Is turned clockwise.

Since also by this pivoting movement of the pivot plates 6 the guide element 5 is pivoted, this occurs Issuing movement, with its longitudinal slot 18 the guide finger 17 takes the rotary fork 15 and so the twisting the rotary fork 15 causes, which after complete Exhibiting movement of the guide element 5 the guide roller 13 of the door leaf 2 from the area of the tines 14 of the now twisted rotary fork 15 comes what it Drive permitted, door leaf 2 now via the drive arm 11 in the opening direction along the guide element 5 move.

Coordinating the movement of the second door leaf 1 is preferably carried out by a circulating rope or a Timing belt or the like., With the door leaf 1 on one of the two Dream, the door leaf 2 is hinged to the other, so that it is ensured that the two door leaves are always symmetrical are positioned with respect to the plane of symmetry 20.

In the preferred variant shown, the guide fork is 15 so loaded by a spring mechanism 21 that they are always under the action of this spring mechanism 21 is pushed into one of the two possible end positions. On This ensures that vibrations or the like. when the door is open the swivel fork is not the in Fig. 4 shown angular position, compliance is necessary so that the guide pin 13 of the door leaf 2 when closing again in the area of the tines 14 arrives and allows the door to be closed properly.

3, the closed position situation of the fork mechanism corresponding to the door the spring mechanism 21 supports compliance with the Closed position, but what, as explained below, primarily and essentially done in a different way so that it it is also possible to use a torsion spring instead of the spring mechanism 21 in the area of the axle 16 fixed to the body Provide rotary fork 15 which the rotary fork 15 in the corresponding position in the open position, which in FIG. 4 is shown.

The guidance of the door in the floor area and that reliably Keeping the door closed even when the drive is without power according to a preferred variant of the invention on the following Way, which is shown in Fig. 1 achieved: With the Swivel plates 6 are connected via those already mentioned Components also include actuating arms 22 which are non-rotatable with the arm 23 attached to the arm 24 attack. When opening the door and thus when turning the swivel plates 6 thus also become the door tree tubes 23 panned. These door tree tubes 23 carry in the floor area the car body swivel arms 25, which at their free ends by means of rollers or the like 26 in guides 27 of the door leaves 1, 2 intervene and these door leaves in the lower area lead and hold.

It is now advantageous, as can be seen from FIG. 1, provided that the actuating arms 22 in the closed position of the door with respect to the pivot axes 7 come to rest on the side when exercising Pressure on the door leaves 1, 2 in the sense of the opening movement exerts a torque on the swivel plates 6 by that these are charged in the sense of the closing movement. As can be seen in the example shown, this through a dead center situation or an over dead center situation reached, in the course of the closing movement Actuating arms 22 moved beyond the pivot axes 7 become.

As is known per se, this measure makes provision an emergency operating device necessary according to the invention either on the drive or on one of the swivel plates 6 acts in the sense of the opening movement and so too when the motor 8 is de-energized, the door can be opened.

It is in a preferred but not shown, Design possible, reaching the dead center position by lightening a spring on the door tube or the swivel plate or another (or between two) components of the door drive in the closing direction works. This is especially for emergency operation in the event of a failure Drive advantageous.

The invention is not restricted to the exemplary embodiment shown, but can be modified in various ways become. So it is possible instead of the spindle drive to use another linear motor or by a kinematic reversal of the situation with the rotary fork 15 to change if, for example, with the guide element 5 connected a pin, mandrel, fingers or the like. intended is and the pivot fork 15 with a corresponding shaped slot-like guide is provided.

In the exemplary embodiment shown, the drive arm is 11 or his point of attack on the door arm 12 selected so that he As little as possible during the opening or closing movement both sides of the direction of the linear actuator deviates. It goes without saying in special installation situations conceivable, the point of attack closer to the door leaf 2 or further away from it so that the arm 11 to only ever lie on one side of the drive direction is coming. It is also conceivable for special cases, the drive arm 11 rotatably connected to the mother carriage 10 and to provide a slot-shaped guide in the door arm 12, along which the point of application of the drive arm 11 moved during the opening or closing movement.

In the Figura it can be seen that the end of the closing movement is adjustable by a stop 28, this stop does not have to, as in the example shown, be fixed to the car body, but can also through an adjustable rotation restriction between the Drive 29 and the pivot plate 6 or between the guide element 5 and the swivel plate 6 or other, in In the course of the opening and closing movement relative to each other moving parts.

As can easily be seen from FIGS. 1 and 2, everyone can fixed to the car body, interacting with the door mechanism 3 Parts easily on a slim and little space using mounting plate or a mounting profile be, so that ultimately only this mounting profile or this mounting plate is connected to the car body must be to install the entire mechanism 3. The Actuating arms 22, which are the connection to the door boom tube 23 produce, in such a case are preferably adjustable in length trained to accommodate any tolerances between the position of the door tree tubes and the entire drive mechanism 3 balance.
