Description

The invention relates to a device for moving a pivoting sliding door for vehicles for the transport of people, in particular rail vehicles, with the features from the preamble of patent claim 1.

Such a door is described for example in the document FR 2 658 773 A1. In the known device, before the longitudinal movement of the door leaf begins, a rotary movement of the door tree tube is generated by means of its own piston-cylinder drive.

The invention has for its object to provide a device with the features specified in the preamble of claim 1 so that on the one hand no special drive device is required to generate the rotational movement of the door tree tube, but this rotational movement is derived from the longitudinal movement of the door leaf and on the other hand the door leaf during the pivoting is held in the longitudinal direction without the need for a telescopic guide to ensure the sufficient longitudinal displacement.

This object is achieved according to the invention with the features from the characterizing part of patent claim 1. Advantageous developments of the invention are described in the subclaims.

The basic idea of the invention is to achieve, by means of a special guide rail on the door leaf and a control element engaging in this guide rail, possibly in cooperation with locking elements, that the opening of the door takes place in two separate steps, namely once a pivoting out of the leading edge of the door leaf due to the Rotation of the door tree tube depending on the longitudinal movement of the door leaf and on the other hand by the pure longitudinal displacement of the door leaf. It is advantageous if, during the longitudinal movement of the door leaf, the rotary movement of the door tree tube is blocked in the second movement step. Furthermore, can be advantageous in the device according to the invention How to generate the rotary movement of the door tree tube using the reaction force of a drive device for the longitudinal movement of the door leaf.

Two basic embodiments of the device according to the invention are possible and are described below using exemplary embodiments. In a first embodiment, the additional guide rail is arranged in the vertical direction immediately next to the upper guide rail and extends essentially over the entire length of the upper guide rail. Here, the rotational movement of the door tree tube can be brought about by an inwardly directed end section at the front end of the additional guide rail, into which an additional roller arranged on the upper roller lever runs.

In a second basic embodiment, the additional guide rail does not extend over the entire length of the upper guide rail, but is merely designed as a short piece of rail, which directly adjoins the upper guide rail at the front end and has an inwardly directed section. In this embodiment, the control element has a roller running in the additional guide rail, which is arranged at the end of a roller lever, which is part of parallelogram links, by means of which the rotary movement of the door tree tube is effected.

In both embodiments, good guidance of the door leaf is ensured during most of the opening movement. If this guidance is also to be particularly secure in the last section of the longitudinal movement of the door leaf, in which the swivel arm carrying the door leaf moves toward the roller lever supporting the door leaf, it is advantageous if an additional guide which becomes effective when the door leaf is fully pivoted out is present is which has a four-bar linkage and is described in claim 16 and further below.

Exemplary embodiments of the device according to the invention are explained in more detail below with reference to the accompanying drawings.

1 to 4 show a pivoting sliding door installed in a vehicle, not shown, and the device for moving it in a first embodiment. The basic structure of the pivoting sliding door, which also applies to the other embodiments, is first explained with reference to FIG. 1. The door leaf 1 has a swivel arm 2 with a support member 4 designed as a slide, which is displaceably guided on a guide element 3 designed as a rail and running horizontally in the longitudinal direction of the vehicle. Furthermore, a control roller 33 is arranged on an auxiliary arm 34 which is connected to the swivel arm 2 and which engages in a guide rail 32 which is fixedly connected to the door frame 15 and which is curved inwards at one end. The drive device of the door has an electric motor 18, the output element 18a of which is connected via a toothed belt 18b to the input element 19a of a reduction gear 19, the output element 19b of which drives a rotating toothed belt 19c guided along the guide element 3, which at the end opposite the reduction gear 19 via a Deflection roller 19d runs. The support member 4 is connected to the toothed belt 19c via a connecting element 4a.

For further guidance and for pivoting out the door leaf 1, a rotatably mounted, vertically positioned door tree tube 5 is provided on the door frame 15, on which a first roller lever 9 is arranged in the upper region of the door leaf, said lever lever 9 being arranged horizontally via a guide roller 9a extending guide rail 6 engages. In the lower area of the door leaf 1, an analog roller lever 10 is arranged on the door tree tube 5, which engages via a guide roller 10a in a corresponding guide rail 7 arranged on the door leaf 1 (see FIG. 4).

In the exemplary embodiments shown, the reduction gear 19 is designed and arranged such that the axis of its output element 19b is vertical. The housing of the reduction gear 19 is rotatably supported on the door frame in a manner not shown, which is coaxial with the axis of the output element 19b. Furthermore, a first gearwheel 20a is arranged on the housing of the reduction gearbox 19 coaxially to the axis of rotation, which meshes with a second gearwheel 20b to which a coupling rod 28 is fastened, which is articulated to a swivel arm 29 which is fixedly arranged on the door tree tube 5 (FIG. 4) .

A further guide rail 8 (see FIG. 4) runs on the door leaf 1 immediately below the upper guide rail 6 and parallel to it, into which a second guide roller 11 engages, which acts on the roller lever 9 at a horizontal distance from the guide roller 9a at a kink of the roller lever 9 is arranged, as can be seen from FIGS. 2 and 3. The additional guide rail 8 has at its end facing the door tree tube 5 an inwardly guided end section 8a, which is open at the front, so that, as can be seen from FIGS. 2 and 3, the guide roller 11 enters and exits this end section 8a during the closing movement exits him.

The mode of operation of the device for moving the pivoting sliding door shown in FIGS. 1 to 4 is as follows:
In the closed state of the door leaf 1 shown in FIGS. 1 and 2, the roller lever 9 is guided inwards and the additional guide roller 11 emerges from the end section 8a of the additional guide rail 8. The coupling rod 28 is, as can be seen in FIG. 2, in a dead position locking the door tree tube 5 and the door leaf 1. This means that the door leaf 1 cannot be easily moved in the transverse direction, for example by pressing from the inside. To initiate the opening movement, the electric motor 18 of the drive device is switched on, as a result of which the support member 4 is set in motion in the longitudinal direction via the reduction gear 19 and the toothed belt 19c. Due to the reaction force occurring on the housing of the reduction gear 19 during the drive movement, a torque is exerted on the housing, by means of which the housing is rotated clockwise in the direction of arrow A1 in the illustration in FIG. 2 at the beginning of the opening movement. This rotary movement of the gear wheel 20a is transmitted to the gear wheel 20b (arrow direction A2), the coupling rod 28 being carried along and being guided out of the dead center. The roller lever 9 is pivoted outwards and with it the leading edge of the door leaf 1. As the longitudinal movement begins, the additional guide roller 11 can run into the end section 8a of the additional guide rail 8, so that finally in the fully pivoted-out state, as shown in FIG. 3, the rollers 9a and 11 are at a horizontal distance in the longitudinal direction in the upper one Guide rail 6 or the additional guide rail 8 are located, which has the consequence that the rotational movement of the door tree tube 5 is blocked. This ensures that the exact guidance in its plane of movement is retained in the pure longitudinal movement of the door leaf 1. This occurs in the closing direction until the blocking is released again at the end of the closing movement by the additional guide roller 11 running into the curved end section 8a of the guide rail 8. Finally, due to the torque generated by the corresponding reaction force on the housing of the reduction gear 19 and the corresponding rotation of the gears 20a and 20b, the coupling rod 28 and with it the door boom tube 5 and the roller lever 9 are returned to the position shown in FIG. 2, in which the Coupling rod 28 comes into the dead position already explained and the door leaf 1 is locked in the closed position.

A somewhat different embodiment of the device for moving the pivoting sliding door is explained below with reference to FIGS. 5 to 7. 5 to 7 only the part of the pivoting sliding door located in the region of the door tree tube is shown, which has the changes compared to the embodiment according to FIGS. 2 to 4. Components of the embodiment according to FIGS. 5 to 7, which correspond exactly to the components of the embodiment according to FIGS. 2 to 4, are identified by a '. The connection of the door leaf 1 via the swivel arm 2 with the support member 4, which is displaceable on the guide element 3, and the guide of the support member 4 on the guide rail 32 are formed as shown in Fig. 1. Likewise, the drive of the door movement with the electric motor 18, the reduction gear 19 and the toothed belt 19c is designed analogously to FIG. 1. The transmission of the reaction force of the drive from the housing of the reduction gear 19 again takes place via a gear transmission 20a 'and 20b', a cam disk 30 being arranged on the gear 20b ', with which the coupling rod 28 acting on the door boom tube 5' via a pivot arm 29 '' connected is. The door leaf 1 'is guided in the region of the door tree tube 5' via the upper roller lever 9 ', the guide roller 9a' of which engages in the upper guide rail 6 'arranged on the door leaf 1'. In an analogous manner, the door leaf 1 'is supported in the lower area via the lower roller lever, not shown.

In this embodiment, the additional guide rail does not extend over the entire length of the upper guide rail 6 ', but is designed as a short rail piece 16, which is arranged at the front end of the upper guide rail 6' in the opening direction directly after this and is guided inwards. In this embodiment, the rotation of the door boom tube is blocked via a two-armed lever 12a-12b, the fulcrum of which lies at the outer end of the upper roller lever 9 ', one arm 12a of the lever carrying a guide roller 17 and the other lever arm 12b carrying a guide roller 31. 5, the arrangement is such that in pivoted-in state of door tree tube 5 'and door leaf 1', the guide roller 17 has been moved into the rail section 16, while the guide roller 31 is located within an opening 6a '(FIGS. 5 and 7) of the upper guide rail 6'. 5 and 6, together with the upper roller lever 9 ', a single-arm pivot lever 13 arranged on the door tree tube and a coupling rod 14 connecting the two pivot levers 12b and 13, a quadrilateral joint. The arrangement is such that the two pivot levers 12b and 13 thereby form a pair of parallelogram links. At the end of the pivot lever 13 there is an extension with a guide roller 13a which bears against the cam disk 30.

The operation of the embodiment of the device for moving the pivoting sliding door shown in FIGS. 5 to 7 is as follows:
In the closed state of the door leaf 1 'shown in FIG. 5, the coupling rod 28' is again in a dead position, so that the door leaf 1 is locked in this position and cannot be moved outwards by pressing. When the drive is switched on, the gear 20b 'moves in the direction of arrow A2' as a result of the reaction force which occurs, as a result of which the coupling rod 28 'is carried along and the roller lever 9' is pivoted outwards. In this case, the four-bar linkage is taken along and in this first movement step a small longitudinal movement of the door leaf 1 'is already brought about.

The cam disk 30 rotates with the gearwheel 20b 'until the guide roller 13a arranged on the extension of the pivot lever 13 finally engages in a groove 30a on the cam disk 30 and the parallelogram links 12b and 13 are guided inwards. In this position, the roller lever 9 'is pivoted out fully and the door tree tube 5' is in the end position of its rotation. The articulated quadrilateral is blocked by the control roller 13a engaging in the groove 30a (see FIG. 6) and thus the door tree tube 5 'is locked against rotation. The control roller 17 runs out of the rail section 16 into the guide rail 6 ', with the result that, as can be seen from FIG. 6, the guide roller 31 emerges from the opening 6a' and runs along the outside of the upper guide rail 6 ' , whereby the guide roller 13a is fixed in the groove 30a. By guiding on the two-armed lever 12a-12b with the guide rollers 17 and 31, the door leaf 1 'is precisely guided in its plane of movement at this point, while it is displaced in the longitudinal direction up to the full opening width.

During the closing movement, the lock is released by running the guide roller 17 into the rail section 16 and correspondingly pivoting the pivoting levers 12b and 13, and the coupling rod 28 'into the coupling rod 28' shown in FIG. 5 shown locked position returned.

Since in the course of the opening movement of the door leaf 1 or 1 'the distance between the door leaf 1 in the area of the trailing edge leading swivel arm 2 and the guide devices coupled to the door tree tube 5 becomes smaller, it may be expedient to provide an additional guide for the door leaf 1, which is effective in the fully swiveled-out state during the longitudinal movement. Such an additional guide is shown below with reference to FIGS. 8 and 9, in which the pivoting sliding door is shown in the region of the trailing edge of the door leaf 1 in the closed state and in the swung-out state at the beginning of the longitudinal movement.

This additional guide device has a four-bar linkage which consists of the swivel arm 2, which is extended beyond its articulation point on the support member 4, a section of the door leaf 1 in the longitudinal direction, a link 24 connected to the swivel arm extension 2a, and a coupling member 26 connecting the link 24 to the door leaf 1 is constructed. The articulation points are designated with reference numbers 21, 22, 25 and 23. At the articulation point 25 there is a locking element 25a in the form of an elongated bolt and on the support member 4 there is an extension 27 with a groove 27a. In the first phase of the opening movement when swiveling out, the swivel arm 2 is swiveled via the guide roller 33 engaging in the guide rail 32 on the guide arm 34 connected to the swivel arm 2 and, as can be seen from FIGS. 8 and 9, the arrangement of the four-bar linkage is made in this way that in the final phase of the pivoting movement, the locking element 25a runs into the guide groove 27a.

As a result, the four-bar linkage is fixed in its position and the door leaf 1 is supported against rotation via the four-bar linkage at the pivot points 21 and 23.
