EP0716004A1 - Pivoting and sliding door for passenger-transporting vehicles - Google Patents

Abstract

The pivoted sliding door has the door panel (1) coupled to a sliding carrier element (4), displaced along a guide (5) extending horizontally in the train longitudinal direction, via a pivot arm (3). This is coupled to the door panel and the carrier element via respective vertical rotation axes (3.2,3.1), with its pivot movement determined by a guide lever (3.3) cooperating with a guide rail (6). The door panel is rotated abut the vertical pivot axis at the beginning of the opening movement via a two-part linkage (9.1,9.2) between the door panel and the carrier element.

Description

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

Such a pivoting sliding door is described for example in DE 32 31 181 A1. In this known pivoting sliding door, a further pivot arm is arranged between the door leaf and the supporting member, so that the door leaf is guided parallel to itself during the pivoting-out movement due to the guidance by parallelogram links. However, it is desirable for pivoting sliding doors to additionally pivot the door leaf slightly about a vertical axis even at the start of the opening movement, so that the trailing edge of the door leaf emerges from the door frame at the beginning of the opening movement and the sliding movement can therefore also begin. Such Swivel sliding door is described for example in EP 0 320 591 A2. In this known pivoting sliding door, the guide element itself can be pivoted transversely to the plane of the door leaf by means of two cranks with vertical crank axes, and the additional pivoting of the door leaf about the vertical axis is achieved by the cranks together with a rigid coupling element that connects them and carries the guide element and the with the door frame firmly connected crank pin form a quadrilateral joint with opposing cranks.

The invention has for its object to provide a pivoting sliding door with the features from the preamble of claim 1 so that pivoting of the door leaf even at the beginning of the opening movement is also possible about a vertical axis without the guide element and thus possibly the drive means also pivoted out need to be, ie it should be possible to achieve this additional pivoting of the door leaf with the least possible design effort and less space requirement. Furthermore, it should be possible to derive this additional pivoting of the door leaf from the longitudinal movement of the door leaf.

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

The basic idea of the invention is to connect the door leaf to the support member not via an additional swivel arm, but via a two-part link connection and during a first section of the opening movement in the longitudinal direction to carry out a relative pivoting between the two parts of the link connection such that the position of the Coupling point of the handlebar connection changes with respect to the axis of rotation of the swivel arm arranged on the support member and thus the door leaf is given an additional swivel movement.

Advantageous embodiments for generating this relative pivoting are described in claims 2 to 4. Furthermore, it has proven to be particularly advantageous if the pivoting sliding door according to the invention additionally has the features of claims 8 to 13, according to which the rotary movement of a door tree tube is generated using the reaction force of a drive device for the longitudinal movement of the door leaf.

Exemplary embodiments of the pivoting sliding door 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 a device for moving it in a first embodiment. 1 to 4, the basic structure of the pivoting sliding door is first explained. To maintain clarity, in 1 to 4 details, which relate to the control of the relative pivoting of the parts of the two-part link connection explained below, have not yet been shown. They are the subject of FIGS. 5 and 6.

The door leaf 1 is connected via a swivel arm 3 to a support member 4, which can be designed, for example, as a spherical sleeve and is displaceably guided on a guide element 5 which is designed as a round rod and runs horizontally in the longitudinal direction of the vehicle. The guide element 5 is firmly connected to the door frame 2 via fastening devices 5.1 and 5.2. The swivel arm 3 is connected to a fixed attachment 1.1 on the door leaf 1 via a vertical axis of rotation 3.1 and to the support member 4 via a vertical axis of rotation 3.2. On the swivel arm 3 there is a guide lever 3.3 which carries a control roller 3.4 which engages in a guide rail 6 which is fixedly connected to the door frame 2 and which runs parallel to the longitudinal direction of the vehicle and is guided inwards at one end. Furthermore, the door leaf 1 is connected to the support member 4 via a two-part link connection, the part 9.1 of this link connection articulated on the support member 4 via a vertical axis of rotation 9.5 as a pivot point being connected via a vertical axis of rotation 9.4 as a coupling point to the other part 9.2, which itself a vertical axis of rotation 9.3 is connected to the door leaf 1 as a pivot point. The part 9.1 of this two-part link connection articulated on the support member 4 can be pivoted in a forcibly guided manner during the longitudinal movement of the support member. This is in the 1 to 4 are not shown and will be described below with reference to FIGS. 5 and 6.

The drive device of the door has an electric motor 7 with an output shaft 7.1, on which an output wheel 8.1 is arranged, which drives a rotating toothed belt 8 guided along the guide element 5, which runs at the end opposite the motor 7 via a deflection roller 8.2. The support member 4 is connected to the toothed belt 8 via a connecting element 4.1.

For further guidance and support when the door leaf 1 is pivoted out, a vertically arranged door tree tube 10, which is arranged on the door frame 2 and is rotatably mounted in bearings 10.1 and 10.2, is provided, on which a first roller lever 11 is arranged in the upper region of the door leaf, which lever 11.1 in via a guide roller a horizontally extending guide rail 1.2 arranged on the door leaf engages. In the lower area of the door leaf 1, an analog roller lever 13 is arranged on the door tree tube 10, which engages via a guide roller 13.1 in a corresponding guide rail 1.3 (see FIG. 4) arranged on the door leaf 1.

Furthermore, a pivot lever 12 is arranged at the upper end of the door tree tube 10, which is articulated via a coupling rod 14 at a point 14.1 of a gearwheel 15 with which it forms a crank mechanism. The gear 15 engages in a gear 7.2, which is fixed is connected to the housing of the electric motor 7 which is rotatably mounted on the door frame 2 and whose axis of rotation runs coaxially with the axis of the output shaft 7.1 of the electric motor 7 (see FIG. 4).

In Fig. 5 in an enlarged view compared to Fig. 1, the right part of the closed sliding sliding door in Fig. 1 is shown and it can be seen that in this embodiment the articulated on the support member 4 part 9.1 of the two-piece link connection is designed as a two-armed lever, the one end is connected to the other part 9.2 of the handlebar connection, while the other end 9.6 carries a further guide roller 9.7 which runs in a second guide rail 16 which is firmly connected to the door frame 2. 5, this second guide rail first has a slight curvature downwards in its first section and then again a slight curvature upwards, after which it is continued in the vehicle longitudinal direction.

5, is constructed such that when the door is closed, the axes of action of the swivel arm 3 and the part 9.2 of the handlebar connection connected to the door leaf run essentially parallel when the door is closed.

To open the door, when the drive motor 7 is actuated, the support member 4 is set in motion along the guide element 5 via the toothed belt 8. The pivot arm 3 and carried the two-part link connection via the articulation point 9.5. The guide roller 3.4 runs in the first guide rail 6, so that the pivot arm 3 is impressed with a pivoting movement to the outside. The guide roller 9.7 runs in the second guide rail 16. As a result of the downwardly curved design of this guide rail 16, the result that the part 9.1 of the link connection Fig. 5 articulated on the support member 4 executes a clockwise movement, which has the consequence that the coupling point 9.4 between the two parts of the link connection with respect to the arranged on the support member 4 axis of rotation 3.2 of the swivel arm 3, so that the link connection extends and the door leaf 1 an additional rotary movement about the axis of rotation 3.1 between the swivel arm 3 and the approach 1.1 of the door leaf 1 is granted. This additional rotary movement has the result that the left edge in FIGS. 1 and 2, that is to say the front edge of the door leaf 1, is rapidly guided outwards, so that an immediate displacement of the door leaf 1 in the course of the longitudinal movement is possible. At the same time, as a result of the reaction torque occurring when the electric motor 7 starts on the housing, the gear 7.2 is given a clockwise rotary movement, by means of which the door boom tube 10 is rotated in the sense that the roller levers 11 and 13 can be pivoted outwards. The door leaf 1 slides, guided and supported on the roller levers 11 and 13, in the end position shown in Fig. 3.

In this end position of the door tree tube 10 corresponding to the fully swiveled-out state of the door leaf 1, the rotational movement of the door tree tube is limited by the pivot lever 12 resting against a stop 24. This ensures that the exact guidance in its plane of movement is retained in the pure longitudinal movement of the door leaf 1. At the end of the closing movement, on the one hand, by correspondingly controlling the two-part link connection, a rotary movement of the door leaf 1 inwards to the parallel position of the swivel arm and handlebar part 9.2 is achieved, while on the other hand through the effect of the reaction torque of the drive motor via the gears 7.2 and 15 and the coupling rod 14 and the pivot lever 12 rotates the door tree tube 10 and the roller levers 11 and 13 are guided inwards. In the closed state of the door, as can be seen from FIG. 1, the corresponding end position of the door tree tube 10 is blocked by the coupling rod 14 which bears against a stop 25 directly behind a dead position.

In Fig. 6 a variant of the device for controlling the pivoting of the articulated on the support member 4 part 9.1 of the two-piece link connection is described. In FIG. 6, all parts corresponding to the parts according to FIGS. 1 to 4 are identified with the same reference numerals as there, while parts which correspond in their function to variants of parts from FIG. 5 are each provided with an apostrophe.

In this embodiment too, the part 9.1 'of the link connection articulated on the support member 4 via the axis of rotation 9.5' has a second lever arm 9.6 'which carries a guide roller 9.7'. Furthermore, a guide roller 9.8 'is also arranged on part 9.1'. The two guide rollers 9.7 'and 9.8' rest positively on the guide surface of a cam 17, which is rotatable about the vertical axis of rotation 3.2 'between the link arm 3 and the support member 4 and is firmly connected to the link arm 3. This has the consequence that, according to the shape of the cam 17 at the beginning of the opening movement, the part 9.1 'of the link connection articulated on the support member 4, the additional movement already described is impressed clockwise, which relocates the coupling point 9.4 between the two parts of the link connection in relation to the axis of rotation 3.2 'of the swivel arm 3 arranged on the support member 4 and thus leads to the extension of the link connection and to the generation of the additional rotary movement of the door leaf 1 about the vertical axis 3.1. In its other features, the pivoting sliding door is constructed in accordance with the features of FIGS. 1 to 4 and the mode of operation is corresponding.

A further embodiment of the pivoting sliding door described is explained below with reference to FIGS. 7 and 8, which differs in the generation and control of the movement of the door tree tube 10 from the embodiment according to FIGS. 1 to 6. In the remaining features, this embodiment corresponds to the pivoting sliding door according to FIGS. 1 to 5 or 1 to 4 and 6. The features described on the basis of these figures are not explained again below and the parts corresponding to the parts of the embodiment according to FIGS. 1 to 4 are designated by the same reference numerals as there.

Also in the embodiment according to FIGS. 7 and 8, the drive device has an electric motor 7 with a housing rotatably mounted about an axis of rotation lying coaxially to the output shaft 7.1, to which a gearwheel 7.2 is fastened which engages in a gearwheel 15. In this case, the gear wheel 15 is not connected to the pivot lever 12 on the door tree tube 10 via a rigid coupling rod, but rather via a two-part coupling element made of parts 18 and 19. In the area of the connection point 19.1 between the parts 18 and 19, a leg spring 18.1 is arranged so that in the closed position of the door shown in Fig. 7, the two parts 18 and 19 are in the extended position to each other and are fixed in this position. This has the consequence that in this position the door tree tube 10 is blocked against rotation, for example by pressing from inside the door leaf 1, as a result of the two-element coupling element which is stretched directly behind a dead position and abuts a stop 26. When the door is opened, the gear 7.2 is rotated clockwise and the gear 15 counterclockwise up to a stop 15.1 due to the reaction torque of the drive motor 7, which means that the part 19 is carried along and by the force of the leg spring 18.1 is pivoted relative to part 18, so that a rotary movement of the door leaf 1 is possible in the manner already described, which in this case is only effected by the two-part link connection 9.1-9.2. In the fully swiveled-out state of the door shown in FIG. 8, a locking element 19.2 engages at the connection point between the part 19 and the gear wheel 15 in a locking device 20, which has a substantially T-shaped locking part, with a longitudinal bar 20.1 and a transverse bar 20.2 . The crossbeam 20.2 can be pivoted about a vertical axis of rotation 20.3, counterclockwise pivoting counteracting the force of a compression spring 21 which holds the crossbar at a stop 20.5. At the free end of the longitudinal beam 20.1 there is a locking surface 20.4 on which the locking element 19.2 bears. This configuration blocks a rotary movement of the gear wheel 15 in a direction that corresponds to a pivoting inward of the pivoting lever 12 or roller lever 11. A trigger rod 22 is connected to the end of the crossbeam 20.2 facing away from the axis of rotation 20.3 and runs in a guide 23 arranged fixedly on the door frame 2 and has a hook 22.1 at its free end. When the door is finally closed, as can be seen in FIG. 7, the hook 22.1 engages behind an attachment 4.2 on the support member 4 immediately before the end position is reached. In this way, in the final phase of the closing movement, a pull is exerted on the release rod 22 which the crossbeam 20.2 against the action of the spring 21 is given a slight clockwise movement and thereby the locking element 19.2 is released again, so that due to the reaction torque of the drive motor 7 via the gears 7.2 and 15, the part 19 of the coupling element again in the in Fig. 7th position shown can be traced.

It is pointed out that an electric motor is described as the drive device in the exemplary embodiments shown. Of course, it is also possible to use other drive devices, for example a pneumatic drive. It is also possible to provide a central drive for the two door leaves in the case of a door with two door leaves.
