Description

The invention relates to a pivoting sliding door for vehicles, in particular a passenger door for local public transport vehicles with the features from the preamble of the claim 1.

Such a door is described for example in EP 1 040 979 A2.

In the known door points in an embodiment with two against each other sliding door leaves the carrying guide two in Offset in the transverse direction and in the longitudinal direction guide rails extending over the entire door opening which each have a roller carriage slidably suspended in the longitudinal direction is connected to one of the door leaves. The two guide rails of the support are in a common Carrier with an essentially I-shaped profile integrated, on the outward-facing side of a roller carriage and on its side the other roller carriage is hung on the inside is. Such swivel sliding doors require depending on the type of the vehicle and the formation of the door leaves when installed in the Vehicle a considerable adjustment effort.

The invention has for its object a pivoting sliding door with the input and specified in the preamble of claim 1 Characterize so that the adjustment and assembly the door even with very different designs of the door leaves and the vehicle with the same support without major adjustment effort is possible.

In addition, the drive device and carrying guide of the swivel sliding door be structurally simple and only have a small footprint in the vehicle.

This object is achieved with the Features from the characterizing part of patent claim 1. Advantageous developments of the invention are in the dependent Described claims.

The basic idea of the invention is neither the carrying guide with the already mentioned carrier with an I-shaped profile, on which Roller sledges are still running, as is known per se, by means of a round bar on which one is connected to the door leaf Ball sleeve is guided. Rather, one becomes from other applications known linear guide used because of their Training is able to tilt moments around the direction of movement take. The guide rail of such a linear guide has flat outer surfaces which are surrounded by the guide carriage, whereby, if necessary, is achieved by undercuts that the Guide carriage essentially free of play on the guide rail is performed and in particular no movements due to Tipping moments around the direction of movement can occur. This Training the load-bearing guide opens the door leaf swinging on appropriately designed suspension brackets to hang the support arm connected to the guide carriage. This measure makes adjustments in the area of Carrying guide largely unnecessary.

With a pivoting sliding door with two against each other in its longitudinal direction sliding door leaves, it is advantageous if the guide rails the linear guides are superimposed in a space-saving manner arranged on the top and bottom of a guide beam are. The guide slides can then be arranged that their ranges of motion are separate, and the Support arms can be arranged so that during movement partially in the closed position slide and support arms gliding over each other.

The following is a reference to the accompanying drawings Embodiment for a pivoting sliding door according to the invention explained in more detail.

The drawings show:

Fig. 1, the carrying guide of a pivoting sliding door with two Door leaves in a partial view seen from above when open doors;

Fig. 2 shows the carrying guide in a representation analogous to FIG. 1 closed door;

3 shows the support guide according to FIGS. 1 and 2 in an isometric, partially exploded representation;

Fig. 4 shows the support according to Fig. 1 to 3 in a section the line IV-IV in Fig. 2;

5 shows the support guide according to FIGS. 1 to 4 in a slightly enlarged, Isometric partial view from the side of the door leaves removed door panels seen here;

6 shows a section along the line VI-VI in FIG. 5th

The sliding sliding door shown in the drawings is as double-leaf door, but the door leaves themselves in the Figures are not shown.

To hang the door, as can be seen from Fig. 3, in the upper Area of the door frame, not shown, with a support plate 1 Sidewalls 1.1 and 1.2 used. On the side walls 1.1 and 1.2 are on the inside rails 2.1 and 2.2 for transverse guidance the support guide arranged. The carrying guide 3 itself has one that extends over almost the full width of the door opening Guide bracket 3.1, the frame parts 3.2 at both ends and 3.3, each with roller guides 3.21 in the Rails 2.1 and 2.2 are running. As can be seen from Fig. 4, the guide bracket 3.1 has a substantially T-shaped profile that around Is rotated 90 °, and on the now horizontal The center web of the guide carrier 3.1 are on the top and on the bottom each guide rails 4.1 and 4.2 one Linear guide arranged. Run on rails 4.1 and 4.2 that Guides 5.1 and 5.2 comprising rails on three sides, the formation of the guide rails and the guide carriage is such that the linear guide tilting moments about the direction of movement receives. On the slide 5.1 there is one opposite the guide rail offset outwards and parallel to it arranged support arm 6.1 arranged. In an analogous manner, on Guide carriage 5.2 a support arm 6.2 arranged. The support arms 6.1 and 6.2 run horizontally parallel to the direction of displacement of the Guide carriage in the opposite direction. Here is the arrangement such that the range of motion of the guide carriage with the support arms are completely separated from each other, so that, as can be seen from Fig. 2, guide carriage and support arms in the The closed position is partially overlapping.

On the support arms 6.1 and 6.2 are each via suspension brackets 12 (Fig. 5) hung the door leaves in a manner not shown. The suspension brackets are designed so that the Door leaves above them by a parallel to the guide rails 4.1 and 4.2 running axis are suspended in an oscillating manner. As a drive device serves one in the area of one end of the support arranged electric motor 7. For generating the longitudinal movement the slide 5.1 and 5.2 and thus the longitudinal movement the door leaf is the output shaft of the electric motor 7 via a Helical gear 9 connected to two threaded spindles 9.1, 9.2 which each one of the guide carriages 5.1 or 5.2 via spindle nuts is coupled so that the two guide carriages 5.1 and 5.2 and with them the two door leaves in opposite directions Run direction in an opening and closing movement.

The load-bearing guide is in the rails for the movement in the transverse direction 3 from a closed position, in which the door leaves in the Vehicle wall are in a sliding position in which the door leaves lie outside in front of the vehicle wall, and can be moved back. The Force for this displacement of the support guide 3 is from the reaction force of the electric motor 7 derived. The housing of the Electric motor 7 about an axis of rotation aligned with the output shaft rotatably supported on the support guide 3 and via a bevel gear 7.1 connected to a two-armed spreading lever 8, the a lever arm carries a role 8.1, which acts as a support part and supports rail 10 designed as a degree guide. The Rail 10 is fixed to the base plate 1 in the door frame. The other lever arm of the spreading lever 8 is via a coupling rod 8.2 connected to a lever arm of a second spreading lever 8.3, whose other lever arm carries a role 8.4, which also in a the base plate 1 fixed guide rail 11 runs. The in Fig. 2 left end portion 11.1 of this guide rail 11 is used thus as a supporting part for the action of the second spreading lever 8.3.

The operation of this arrangement for transverse displacement of the Carrier guide 3 is as follows. When switching the electric motor on and off 7 is the reaction movement of the housing via the bevel gear 7.1 on the first spreading lever 8 and over the coupling rod 8.2 transferred to the second spreading lever 8.3. In the course of Swiveling movement of the spreading levers 8 and 8.3, which extend over the rollers Support 8.1 and 8.4 on the support parts 10 and 11.1, the Carrier guide 3 together with the door leaves and the one on the carrier guide arranged electric motor 7 and all drive connections out in the transverse direction until it is in the shift position device in which the spreader lever shown in Fig. 1 To take position. As soon as this shift position is reached and the further movement of the load-bearing guide by appropriate stops is stopped, a corresponding torque from the Transfer the output shaft of the electric motor 7 to the spindle drives and the two door leaves move in the opposite direction in the fully open position. When closing the door the reverse process takes place. The two door leaves will first by means of the corresponding reverse torque of the output shaft of the electric motor 7 in the shift position is returned and then due to the reaction force of the drive device the corresponding torque on the spreading lever 8 and 8.3 exercised so that the support guide 3 in the closed position is returned. The arrangement is such that the Carrying guide 3 comes into a dead center position in this position, which too locks so that the door can also be pressed from the inside can no longer be opened.

Compared to the door frame, the carrying guide 3 is additional by a guide roller 11.3 arranged on the guide slide 5.1 performed, in the guide rail connected to the base plate 1 11 runs and in the closed position, as in FIG. 2 can be seen in a transverse section 11.2 of the guide rail 11 enters.

So that when moving the support guide 3 in the transverse direction outside the door leaves in the area of their lower edges to be guided to the outside is a guiding and coupling device provided in the following on the basis of FIGS and 6 for that with the support arm 6.1 or the guide slide 5.1 connected door leaf is explained. In and with the door frame A rotating column 13 is rotatably connected via bearings 13.4 and 13.5 arranged. The upper end of this rotary column 13 is over a Swivel lever 13.3 and a connecting rod 14 with an approach 14.1 of the support guide 3 connected. When moving the Support 3 and thus the approach 14.1 in the direction of arrow A pivots as a result of its connection via the connecting rod 14 the pivot lever 13 in the direction of arrow B and rotates the rotating column 13. At the lower end of the rotating column 13 is a support lever 13.1 in a roller guide 13.2, the guide rails, not shown engages on the inside of the door leaf. At the Returning the support to the closed position will also the door leaf through the opposite rotation of the rotating column returned by means of the roller guide 13.2.
