Description

The invention relates to a sliding door pivot for vehicles, in particular a passenger door for vehicles of public transport, with the features of the preamble of claim 1. Such sliding doors are known in different embodiments and, for example, in EP 1 040 979 A2 and EP 1 314 626 A1 described.

In the document US-A 4503638 is a suspension device for the door of a swing-sliding door for vehicles, especially rail vehicles described. The door leaf is attached via a pivoting arm to a frame which is mounted displaceably on a horizontally arranged support rod. Furthermore, in the lower region of the door leaf, a guide rail is provided in which rollers run, which are fastened to a pivoting arm, which is pivotable about a pivot axis arranged on the door frame.

It has been found that in such sliding doors, the installation and adjustment of the door in the door frame of the vehicle is very time consuming because inaccuracies in the dimensions and the orientation of the door frame must be compensated by special adjustments, such as the lining of screws. It must be achieved by the adjustment that the door leaves run smoothly and without jamming both in the transverse movement and in the longitudinal movement.

The invention has for its object to design a sliding door with the features of the preamble of claim 1 so that during assembly of the door in the door frame, the adjustments can be done much less expensive and thus considerable time can be saved in the assembly work. Furthermore, the sliding door according to the invention should be designed simply and inexpensively and it should be prevented jumping of the rotary column in the event of strong shocks.

The solution of this object is achieved according to the invention with the features of claim 1. Advantageous developments of the invention are described in the dependent claims.

A basic idea of the invention is to provide special adjustment possibilities both on the transverse guides of the carrying guide and in a particularly advantageous embodiment with regard to the longitudinal guidance of the door leaves, by means of which clamping movements of the carrying guide in the transverse direction and possibly of the door leaves in the longitudinal direction can be achieved in a few steps can be achieved. It has been shown that with the sliding door according to the invention, the assembly time can be reduced to at least 25% of the usual assembly time. Furthermore, it has been shown that the pivot sliding door according to the invention can be produced in a simple and space-consuming construction and the jumping of the rotary column is prevented by the special nature of their storage.

In the following an embodiment of a sliding sliding door according to the invention will be explained in more detail with reference to the accompanying drawings.

The pivoting sliding door shown in the drawings is designed as a double-leaf door and has a first door leaf 1 A and a second door leaf 1 B. The door leaf 1 A is connected by means of a torsionally rigid support arm 1.1 A with a guide unit 8 A, while the door panel 1 B via a corresponding Support arm 1.1 B is connected to a guide unit 8B. The guide units 8A and 8B are suspended in a carrying guide 3, which is arranged in the upper region of the door portal. The support guide 3 is fixedly connected at its two ends to a frame part 4.1 and 4.2, and each frame part is guided in a direction fixed to the door frame 2 transverse guides in a horizontal direction and transversely to the door opening. The transverse guides have brackets 6.1 and 6.2 connected to the door frame 2, in which transverse guide rails 5.1 and 5.2 are arranged, in which guide rollers 7.1 and 7.2 arranged on the frame parts 4.1 and 4.2 run. The guide rails 5.1 and 5.2 are arranged in the brackets 6.1 and 6.2 such that they are pivotally adjustable about a vertical axis in the horizontal plane. For this purpose, each guide rail is 5.1 or 5.2 respectively connected via three guided in a horizontal plane through the bracket 6.1 and 6.2 screw 17.1 and 17.2 in a horizontal plane adjustably connected to the corresponding bracket.

In the carrying guide 3 is for each door leaf 1A, 1 B extending over a part of the door width, designed as a round rod guide rail 3A and 3B arranged, on each of which the guide rail on three sides comprehensive guide unit 8A and 8B is performed. The tilting moments of the guide units 8A and 8B about the direction of movement are received by a roller guide 15A and 15B, which is pivotally mounted on the door frame 2 and in each case in a near the lower edge of the door panel 1 A and 1 B arranged guide rail 1.2A or 1.2B intervenes.

The guide rails 3A and 3B are stacked and the guide units 8A and 8B are formed so that they can pass each other unhindered. Due to the above-described transverse guides, the carrying guide 3 is displaceable outward together with the door leaves 1A and 1B from a closed position in which the door leaves 1A and 1B are in the vehicle wall to a displaced position in which the door leaves 1A and 1B are outside the vehicle wall lie. In this displacement position, the door leaves 1A and 1B are displaceable in opposite directions until they are in the fully open position shown in the drawings.

In this case, the guide units 8A and 8B are offset from the door leaves 1A and 1B, respectively, with which they are connected in the direction of the respective other door leaf. This offset ensures that the door leaves 1A and 1B release the entire door opening bounded by the door frame 2 in the fully open position.

The fixed to the door frame 2 brackets 6.1 and 6.2 for extending in the transverse direction of guide rails 5.1 and 5.2 are connected via a above the support guide 3 horizontally and parallel to the support guide guide plate 12 firmly connected. In this case, the attachment of the guide plate 12 to the brackets 6.1 and 6.2 via screw 18.1 and 18.2, which are guided by slots 12.41 and 12.42 in the guide plate 12 are, whose longitudinal direction is parallel to the longitudinal direction of the guide plate 12. The advantage of this type of attachment will be explained below.

As a drive device for both the displacement of the door leaves 1A and 1B and for the movement of the support guide 3 in the transverse direction is a motor 9 which is arranged on the support guide 3, that the longitudinal direction of its housing is aligned perpendicular to the guide plate 12 and the housing Guide plate in a transverse movement of the engine 9 permitting elongated opening 12.3 passes. The output element of the motor 9 is connected via a gear 10 with a drive roller 11.1, which forms a belt drive together with a counter-roller 11.2 and a toothed or cam belt 11.3. The guide carriages 8A and 8B are each connected to a run of the cam belt 11.3 such that their longitudinal movement takes place respectively in opposite directions. The motor 9 can basically be designed both as an electric motor and as a rotating fluid motor.

Of course, the motor 9 may also be arranged so that the longitudinal direction of its housing is parallel to the guide plate 12.

The force for the displacement of the support guide 3 in the transverse direction is derived from the reaction force of the motor 9. For this purpose, the housing of the motor 9 is rotatably mounted on the support guide 3 about a rotational axis aligned with the output shaft and connected via a gear, not shown, with a spreading element designed as a two-armed expansion lever 13. The one lever arm of the expansion lever 13 carries a roller 13.1, which is supported in a provided as a support member, provided in the guide plate 12 slot guide 12.1. The other lever arm of the expansion lever 13 is connected via a coupling rod 13.2 with a lever arm of a second expansion lever 13.3, the other lever arm carries a roller 13.4, which runs in a section 12.21 another slot guide in the guide plate 12. This section of the slot guide thus serves as a support member for the action of the second expansion lever 13.3. The slot guide 12.21 is in its further course in a slot guide 12.22 on which a having inwardly curved portion. In this slot guide section 12.22 runs a guide roller 16 which is arranged on the guide unit 8B and at the end of the movement path of the guide unit 8B is guided inwardly, whereby a coordination of the longitudinal and transverse movement of the door leaves 1 A and 1 B is achieved.

The operation of the arrangement for the transverse displacement of the carrying guide 3 is the following. When the motor 9 is switched on and off, the reaction movement of the housing is transmitted to the first expansion lever 13 and via the coupling rod 13.2 to the second expansion lever 13.3. In the course of the pivotal movement of the expansion lever 13 and 13.3, which are supported on the rollers 13.1 and 13.4 in the slot guides 12.1 and 12.21 of the guide plate 12, the support guide 3 together with the door leaves and arranged on the support guide 3 motor 9 and all drive connections in Transversely outwards until it comes into the displacement position in which the expansion lever occupy the position shown in the drawings. Once this displacement position is reached and the further movement of the carrying guide is stopped by corresponding stops, a corresponding torque is transmitted from the output shaft of the motor 9 to the belt drive, 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 are first returned by means of the corresponding reverse torque from the output shaft of the motor 9 in the displacement position, and then the corresponding torque is exerted on the expansion lever 13 and 13.3 due to the reaction force of the drive device, so that the support guide 3 in the closed position is returned. The arrangement is such that each expansion lever in the closed position of the support guide 3 is in a position at or shortly after the dead center of its pivoting movement to lock the support guide 3 in the closed position, so that the door can not be opened by pressing from inside can.

To support the door leaves 1 A and 1 B serve the already mentioned roller guides 15A, 15B. These are each connected by means of a pivoting lever 14.1A, 14.1B with a vertically arranged in the region of the door frame 2 rotary column 14A, 14B. The rotary column is in turn connected at its upper end via a second pivot lever 14.2A, 14.2B with the support guide 3 such that a displacement of the support guide 3 in the transverse direction causes a rotational movement of the rotary column 14A, 14B. As can be seen in particular from FIGS. 1A and 1B, the rotary column 14A, 14B is axially rotatably supported at its lower end by a ball 19, and is displaceable in an axial upward direction against the force of a compression spring 20 arranged at the upper end. This has the advantage that when severe impacts occur in the vertical direction, for example when driving the vehicle through potholes, a jumping of the rotary column upwards due to the correspondingly large-sized compression spring is prevented.

The above-described types of fastening of the transversely extending guide rails 5.1 and 5.2 in the arranged on the door frame 2 brackets 6.1 and 6.2 and the guide plate 12 on the brackets 6.1 and 6.2 brings great advantages in the installation and adjustment of the entire door in the portal opening of a vehicle. So it is for example possible during assembly of the support guide 3 by means of the screw 17.1 and 17.2 the transverse guide rails 5.1 and 5.2 align so that they are strictly parallel to each other in the transverse direction, even if inaccuracies in the orientation of the frame 2 and Mounts 6.1 and 6.2 are present. By this adjustment a clamping in the movement of the support guide 3 is prevented in the transverse direction.

The attachment of the guide plate 12 on the brackets 6.1 and 6.2 through guided through the slots 12.41 and 12.42 screw 18.1 and 18.2 opens up the possibility of self-adjustment of the guide plate 12. To achieve this, the screws 18.1 and 18.2 initially only hand-tight when mounting the door dressed. After assembly, the door is opened by hand opened and closed several times, which has the consequence that the guide plate 12 optimally adjusted on the guided roller 16 in her. Thereafter, the screws 18.1 and 18.2 can finally be tightened.
