The solution of this task is made of according to the invention with the characteristics of the patent claim 1. The advantageous developments of the invention are described in the dependent claims.

A basic idea of the invention consists in provide for special adjustment possibilities in both guides cross sections of the support guide as well as in a form of particularly advantageous embodiment with respect to the guide longitudinal of the door leaves, through whose Adjustment possibilities can be achieved with few manipulations a guide without jamming the support guide in the direction transverse and, if necessary, the door leaves in the longitudinal direction It has been shown that with the door of swivel slide according to the invention can reduce the assembly time at least 25% of the usual assembly time in another case. In addition, it has been shown that the sliding door Swivel according to the invention can be manufactured in a simple construction that requires little construction space, and the jump of the rotating column through the type is avoided Special accommodation.

The following is explained in detail with the help of the attached drawings an exemplary embodiment for a revolving sliding door according to the invention.

In the drawings:

Figure 1 shows and schematic representation the view of a revolving sliding door with two sheets of door in the open state of the door, seen from the inside.

Figure 1A shows zone A of figure 1 in enlarged representation with respect to figure 1.

Figure 1B shows a section according to line C-C in figure 1 representing enlarged with respect to figure 1.

Figure 2 shows a vertical section a through the door according to line A-A in Figure 1

Figures 3 to 5 show in representations isometric from different directions the installation of general drive of the revolving sliding door according to the Figures 1 and 2.

The revolving sliding door represented in the drawings is configured as a two-leaf door and has a first door leaf 1A and a second door leaf 1B. The sheet of door 1A is connected by means of a support arm 1.1A fixed against rotation with a guide unit 8A, while the blade door 1B is connected through a support arm 1.1B corresponding with a guide unit 8B. The 8A guide units and 8B are suspended in a support guide 3, which is arranged in the upper part of the gate's porch. The support guide 3 it is fixedly connected at its two ends with a part of the frame 4.1 and 4.2, and each piece of the frame is guided in a scrollable way in transverse guides fixedly connected to the frame of the door 2 in a horizontal direction and transverse to the hole of the door. The cross guides have 6.1 and 6.2 connected to the door frame 2, in which they are arranged guide rails 5.1 and 5.2 extending in the direction transverse, in which guide rollers 7.1 and 7.2 run, respectively, arranged in frame pieces 4.1 and 4.2. The guide rails 5.1 and 5.2 are arranged in the supports of fixation 6.1 and 6.2, so that they can be adjusted so rotating around a vertical axis in the horizontal plane. Such Finally, each guide rail 5.1 and 5.2, respectively, is connected through three threaded joints 17.1 and 17.2, respectively, guided in a horizontal plane through the fixing bracket 6.1 and 6.2, respectively, adjustable in a horizontal plane with the corresponding fixing bracket.

In the support guide 3, for each sheet of the door 1A, 1B, a guide rail 3A and 3B is arranged, respectively, which extends over a part of the width of the door and which is configured as a round rod, on which the guide unit 8A and 8B, respectively, which surrounds the guide rail on three sides. The tilt components of the guide units 8A and 8B around the direction of movement they are absorbed by a roller guide 15A and 15B, respectively, which is rotatably housed in the frame of door 2 and which fits in each case in a guide rail 1.2A and 1.2B, respectively, which is arranged in the vicinity of the song bottom of door leaf 1A and 1B, respectively.

Guide rails 3A and 3B are placed overlays and guide units 8A and 8B are configured of such that they can move unhindered ones ahead of the others. Under the transversal guides described previously, the support guide 3 can be moved together with the door leaves 1A and 1B from a closed position, in which the door leaves 1A and 1B are located on the wall of the vehicle, to an outward position, in the that the door leaves 1A and 1B are outside in front of the vehicle wall. In this position of displacement, the door leaves 1A and 1B can be displaced in opposite directions to each other, until they are in the fully open position represented in the drawings.

In this case, the guide units 8A and 8B are shifted in front of door leaves 1A and 1B, respectively, with which they are connected, in the direction of the another sheet of the respective door. Through this displacement the door leaves 1A and 1B are achieved in the position fully open release the entire opening of the delimited door by the door frame 2.

Fixing brackets 6.1 and 6.2 arranged fixedly on the frame of door 2 for guide rails 5.1 and 5.2, which extend in the transverse direction, are fixedly connected to each other through a guide plate 12 arranged above the support guide 3 horizontally and in parallel to the support guide. In this case, fixing the guide plate 12 in the fixing brackets 6.1 and 6.2 is made to through threaded joints 18.1 and 18.2, respectively, which are guided through elongated holes 12.41 and 12.42, respectively, in the guide plate 12, whose longitudinal direction extends parallel to the longitudinal direction of the plate guide 12. The advantage of this type of fixing is explained more ahead.

As a drive device for both the displacement of door leaves 1A and 1B as well as for the movement of the support guide 3 in the transverse direction serves a motor 9, which is arranged in the support guide 3 in such a way that the longitudinal direction of its housing is aligned perpendicular to the guide plate 12 and the housing crosses the guide plate in an elongated hole 12.3, which allows a transverse movement of the engine 9. The engine output element 9 is connected through a gear 10 with a roller 11.1 drive, which forms a belt drive along with an opposite roller 11.2 and a toothed belt or cam belt 11.3. The guide carriages 8A and 8B are connected in each case with a branch of the cam belt 11.3 so that its movement longitudinal is carried out in each case in opposite directions each. The engine 9 can be configured, in principle, both as an electric motor as well as a hydraulic motor rotary.

Obviously, the engine 9 may be arranged also in such a way that the longitudinal direction of its housing is extends parallel to the guide plate 12.

The force for the displacement of the guide support 3 in the transverse direction is derived from the force of motor reaction 9. To this end, the motor housing 9 is housed on support guide 3 rotatably around a pivot shaft that is aligned with the output shaft and is connected to an expansion element configured as a lever Extensible 13 with two arms. One of the lever arms of the Extensible lever 13 carries a roller 13.1, which is supported by a grooved guide 12.1 which is provided on guide plate 12 and which It acts as a support piece. The other lever arm of the lever extensible 13 is connected through a rod 13.2 coupling with a lever arm of a second lever extensible 1.3, whose other lever arm carries a roller 13.4, marching in a section 12.21 of another grooved guide on the plate of guide 12. This section of the grooved guide therefore serves as a support piece for the performance of the second lever extensible 13.3. Grooved guide 12.21 passes in its extension following a grooved guide 12.22, which presents a section curved In this grooved guide section 12.22 a roller is running of guide 16, which is arranged in the guide unit 8B and which is guided at the end of the unit's movement path 8B guide inwards, which achieves coordination of the longitudinal movement and the transverse movement of the door leaves 1A and 1B.

The operating mode of the arrangement for the transverse displacement of the support guide 3 is the next. During the connection and disconnection of the motor 9, transmits the reaction movement of the housing on the first extendable lever 13 and through the coupling rod 13.2 on the second extendable lever 13.3. In the course of rotating movement of the extensible levers 13 and 13.3, which rest on rollers 13.1 and 13.4 on grooved guides 12.1 and 12.21 of the guide plate 12, the support guide 3 is driven together with the door leaves and the motor 9 arranged on the guide of bracket 3 and with all drive connections in direction transverse outward until the position of displacement, in which the extendable levers adopt the position represented in the drawings. As soon as it has reached this position of movement and subsequent movement of the support guide has been stopped by means of stops corresponding, the respective torque is transmitted from the engine output shaft 9 on the belt drive and it move the two leaves of the door in the opposite direction to the fully open position. When the door closes, it runs The reverse process The two door leaves are returned in first place by means of the corresponding reverse torque from the output shaft of the engine 9 back to the position of displacement and then exercised, by virtue of force reaction of the drive device, the torque corresponding on the extendible lever 13 and 13.3, so that the support guide 3 is returned to the position closed. In this case, the provision is made that each lever extendable in the closed position of the support guide 3 is found in a position at or slightly behind the neutral of its rotating movement for locking the support guide 3 in the closed position, so that the door cannot be opened anymore neither through pressure from the inside.

For the support of door leaves 1A and 1B The roller guides 15A, 15B already mentioned are used. These guides are connected in each case by means of a rotating lever 141A, 14.1B with a rotating column 14th, 14B arranged vertically in the door frame area 2. The column swivel is connected, in turn, at its upper end, to through a second swivel lever 14.2A, 14.2B with the guide support 3, such that a displacement of the support guide 3 in the transverse direction causes a rotating movement of the rotating column 14A, 14B. How can you deduce especially from figures 1A and 1B, the rotating column 14A, 14B is rotatably housed axially at its lower end on a ball 19, and can be moved in axial direction upwards against the force of a compression spring 20 arranged in the upper end This has the advantage that in the event that produce strong impacts in the vertical direction, for example in the In case of vehicle traffic through potholes, a jump of the rotating column upwards under the spring of compression sized correspondingly strong.

The fixing types explained above of guide rails 5.1 and 5.2 extending in the direction transverse on the brackets is fixed 6.1 and 6.2 arranged in the door frame 2 as well as guide plate 12 on the 6.1 and 6.2 fixing brackets imply great advantages in the assembly and adjustment of the entire door in the porch opening of a vehicle. Thus, for example, it is possible to align during assembly of support guide 3, with the help of threaded joints 17.1 and 17.2 guide rails 5.1 and 5.2 that extend in the transverse direction, so that they extend narrowly parallel to each other in transverse direction, even if present irregularities in the alignment of the frame 2 and the supports of fixation 6.1 and 6.2. Through this setting a jam is prevented during the movement of the support guide 3 in the direction cross.

Fixing the guide plate 12 on the fixing brackets 6.1 and 6.2 through threaded joints 18.1 and 18.2 guided through the longitudinal holes 12.41 and 12.42 opens the possibility of automatic adjustment of the guide plate 12. To achieve this, during the assembly of the door, the screws 18.1 and 18.2 are first squeezed only by hand. After mounting the door slides with the hand on one side for another, which has as a consequence, that the guide plate 12 fits optimally on the roller 16 guided in the same. Then the screws can be firmly tightened 18.1 and 18.2 in a definitive way.
