Description

The invention relates to a carrying guide for sliding doors for rail vehicles with at least one door leaf, with the features of the preamble of claim 1.

From the DE 203 16 764 U1 is a support guide for a double-leaf sliding door for rail vehicles known. Each door leaf is connected by means of a torsionally rigid support or guide arm with a guide unit. The guide units are suspended in a arranged in the upper part of the car body support guide and guided displaceably. The support guide is fixedly connected at its two ends to a frame part and each frame part is guided horizontally and transversely to the door opening in arranged on the door frame transverse guides in one direction. The transverse guides have brackets fixedly connected to the door frames, on each of which a transversely extending guide rail is arranged such that it is pivotally adjustable about a vertical axis in the horizontal plane. This should be reduced when mounting the door in the door frame the required adjustment effort.

To move the door leaf in the transverse direction, the entire carrying guide, on which the motor is arranged, is moved via a lever system in the transverse direction.

The carrying guide, which performs the functions of suspension and stabilization of the door leaves, is in the aforementioned solution an integral part of the drive unit.

The invention has for its object to provide a support guide for sliding doors for rail vehicles with at least one door leaf, which can be used independently of the drive system as a separate unit, can be produced inexpensively and is easy to assemble.

According to the invention the object is achieved by the features specified in claim 1. Advantageous embodiments and further developments are subject matter of claims 2 to 10.

The carrying guide consists of a straight guide element, a longitudinally displaceably arranged on this sleeve and a sleeve mounted on the longitudinally displaceable socket. The guide element, which is preferably formed as a guide tube, is pivotally mounted at one end on the door frame side of the car body, on which the door leaf can be pushed out in the transverse direction, in a vertical axis of rotation. For this a holder for receiving the pivotable in the horizontal direction guide element is arranged on the door frame side.

The longitudinally slidably mounted sleeve on the sleeve is rotatably connected to the guide arm via a vertical axis. For this purpose, the guide arm preferably has a fork-shaped receptacle in which the bushing is pivotally mounted by means of vertically arranged pins or pins.

In the closed state of the door leaf, the guide element assumes a pivoted-in position, which is predetermined by the movement sequence of the door leaf. The end of the guide element, on which the socket is located, is pivoted in the direction of the door interior. During the movement of the door leaf, up to the displacement position extending along the vehicle outer wall, the guide element is moved into a position running parallel to the door leaf. The moving components of the carrying guide exclusively follow the movement of the predetermined kinematics for the opening and closing movement of the door leaf and take no active function in the context of the movement of the door leaf. The support guide is independent in its operation of the structural design of the drive mechanism for the movement of the door leaf. The support guide is thus used as a separate module for different drive systems. For single and double-leaf standard doors this does not exceed the portal width. It is advantageous that the carrying guide can also be used for special doors, z. B. at different movements of the individual door leaves or if it is provided that the movement of the door leaves is not parallel to the car outer contour.

In double-leaf sliding doors a support guide is arranged for each door leaf. If the movement of the door leaves synchronously, the support guides are arranged in mirror image.

The guide element extends over the entire width of the door leaf. The displaceably arranged on the guide sleeve sleeve is slightly shorter in its length than half the length of the guide element. The sleeve located on the sleeve is relatively short and has e.g. a length, which is about ¼ of the length of the sleeve.

The sleeve is secured against rotation about its longitudinal axis.

The guide arm is formed at its protruding from the door leaf end as a fork-shaped receptacle in which the socket is mounted. The sleeve is rotatably held by two vertically arranged pins in the receptacle of the guide arm.

With the beginning of the opening movement of the door leaf, the sleeve is slightly pivoted about the vertical pins arranged in a coaxial position with the sleeve. Thereby Blocking the further sliding movement of the sleeve is prevented on the sleeve.

To entrain the sleeve during the movement of the sleeve, a coupling of sleeve and sleeve or sleeve and guide arm is required. Preferably, a stop collar with two vertically projecting lugs is arranged on the pointing in the direction of the pivot axis of the guide element end of the sleeve. The fork-shaped receptacle of the guide arm has, at its in the door opening direction pointing portions, respectively opposite, a corresponding with the noses recess or opening. When the guide arm is moved to the stop collar, so the guide lugs engage in the openings and there is a coupling between the guide arm and sleeve. With the further movement of the guide arm during the door opening, the sleeve is pulled along. If the movement in the opposite direction during the closing operation of the door leaf, the coupling between the sleeve and the sleeve via a pivotable coupling element, which is decoupled when entering the door in the door opening, when the sleeve has reached its original position again.

The free end of the pivotable guide element is guided opposite to its pivot axis in a horizontal guide, which serves as an abutment. In a single-leaf door, the guide is on the adjacent side of the door frame. The guidance consists e.g. from a U-shaped rail or a plate with a recess. If necessary, guide rollers can still be arranged on the guide element. After reaching a parallel to the door leaf extending position, the guide element is locked in the guide. The lock can e.g. via a claw-shaped lever, which is moved back into its unlocked position during the closing movement of the door leaf.

In a two-leaf door, a stable support is fixedly arranged in the upper part of the car body, in the longitudinal central axis of the door opening, on the opposite side, the horizontal guides for the two guide elements and a common locking element are arranged.

The proposed support guide can be produced inexpensively and is easy to install. It also ensures sufficient stability for so-called "heavy" doors.

In the FIGS. 1 to 6 a sliding door is shown, which is equipped with a door leaf 1, in different positions of the door leaf 1. The outside of the door leaf 1 forms in the closed state of the sliding door with the Fahrzeugau- ßenwand a level ( Fig. 1 ). On the inside of the door leaf 1, a guide rail 3 in the upper area and a guide rails 4 in the lower area (FIG. Fig. 3 ) spaced apart, which are parallel to the inside of the door leaf 1 and at the end pointing in the direction of the rotary column 5 have an outwardly curved portion. The curved portion 3a of the upper guide rail 3 is in Fig. 2 to see.

The door leaf 1 is secured in the upper region to a guide arm 6, which is suspended in a support guide 25 and slidably guided. The support guide 25 consists of a guide tube 26 which extends over the entire width of the door leaf 1 and in a on the right side of the door frame 2 - seen from the entry side - arranged holder 27 is pivotally mounted in a vertical axis of rotation 28. On the guide tube 26 sits a longitudinally displaceable sleeve 29 and on this a socket 30 which is slidably mounted on the sleeve 29. The slidably mounted on the guide tube 26 sleeve 29 is secured against rotation about its longitudinal axis. The anti-rotation is not visible in the drawing.

The sleeve 29 has a length which is slightly shorter than half the length of the guide tube 26. The socket 30 is designed to be short in its overall length, which is approximately ¼ of the overall length of the sleeve 29.

In order to ensure good running properties of sleeve 29 and sleeve 30, they are equipped with known roller or ball guides. The bush 30 is connected to the guide arm 6. For this purpose, the inwardly directed end of the guide arm 6 is formed as a fork-shaped receptacle 31, in which the bushing 30 is pivotally supported by means of vertically arranged pins or pins. The pivot axis or the upper pins 32 are in the Figures 2 and 4 to see. For entrainment of the sleeve 29 during the opening movement of the door leaf 1 by the movement of the guide arm 6, the socket 30 is coupled to the sleeve 29 at. The coupling connection is formed by a arranged on the sleeve 29 stop 33 with two oppositely arranged, vertical guide lugs 34 which engage in arranged on the fork-shaped receptacle 31 recesses or guide slots 35, as in FIG. 5 shown. The required coupling between the sleeve 29 and the sleeve 30 can also be done by other suitable means. To entrain the sleeve 29 during closing movement of the door leaf 1, a not visible in the drawing coupling element is provided, which is pivotally mounted in a horizontal axis and temporarily ensures a positive connection between the sleeve 30 and sleeve 29. When the sleeve 29 has reached its starting position again, this connection is released so that the guided on the sleeve 29 socket 30 can be pulled by means of the guide arm 6 to its original position. The free end of the pivotable guide tube 26 is guided in a guide 37 arranged on the adjacent door frame side 2. The guide 37 is formed as a U-shaped rail and at the end of the guide tube 26 upwardly and downwardly directed rollers are arranged.

In the pivoted position of the guide tube 26, when the guide tube 26 has taken a parallel to the door leaf 1 extending position, the guide tube 26 is locked by means of a locking lever 38. During the closing movement of the door leaf 1, the lock is released before entering the door leaf 1 in the door opening again.

In single-leaf doors or double-leaf standard doors, it is advantageous that the support guide 25 in its overall length does not exceed the portal width.

The in the FIGS. 1 to 4 shown drive mechanism for the sliding door is designed as follows.

The required motive force for transverse and longitudinal displacement of the door leaf 1 is triggered by a DC motor 10, which actuates a linear drive 11 via an intermediate gear, which consists of a linear guide 12 and a guided between two rollers 13 and 14 timing belt 15 ( Figures 2 and 3 ), wherein the roller 14 forms the drive roller.

The linear guide 12 is formed as a double-T-beam with inclined guide surfaces, with an upper and a lower guide rail. On the lower guide track, a first guide unit 16 and on the upper guide track, a second guide unit 17 is arranged, which are movable in opposite directions, synchronously. The two guide units 16, 17 are horizontally offset, each connected to one of the strands of the toothed belt 15.

In the closed state of the door leaf 1, the guide units 16, 17 are each at the outer end of the linear guide 11 (FIG. Fig. 1 ).

In order to control the opening and closing movement of the door leaf 1, control plates 18, 19 (FIG. Fig. 2 ) attached. The first guide unit 16 is temporarily, during the pushing-out movement of the door leaf 1 in the transverse direction, with a lever system 20 in connection.

The lever system 20 is designed as an angle lever, which is mounted horizontally pivotable in the arranged near the door frame vertical pivot column 5.

The angle lever 20 has two legs, wherein the pointing in the direction of the door leaf 1 leg at its front end has guide and support rollers 21 which rest against the upper guide rail 3 attached to the door leaf 1 ( Fig. 1 ). The other, inwardly directed leg has at its protruding end mounted in a vertical axis of rotation guide roller 22 which faces upwards, and is in the closed state of the door panel 1 in engagement with the semicircular opening of the associated control plate 18 ( Fig. 1 ).

The second guide unit 17 essentially takes over the longitudinal displacement of the door leaf 1 and is connected via a control plate 19 with the guide arm 6 in operative connection. For this purpose, the guide arm 6 is equipped at its protruding from the door leaf 1 end with an upwardly directed guide roller 9. The control plate 19 points in the direction of the door leaf 1 and has a crescent-shaped recess which has an enlarged portion in the direction of the guide unit 17, followed by a tapered portion in the direction of the door leaf 1 as a curved path extending to the vicinity of the front end of the control plate 19 extends. The guide roller 9 protrudes in the closed state of the door leaf 1 in the enlarged portion of the recess and is freely movable in this during the pushing out of the door panel 1 in the transverse direction, so floating.

During the pushing out of the door panel 1 in the transverse direction from the door opening in a slightly inclined position, the control unit 16 attached to the control panel 18 is responsible for the control of the movement of the door panel 1. During this phase, the guide roller 22 disposed on the inwardly directed leg of the bell crank 20 engages the semicircular opening of the control plate 18, as in FIG Fig. 1 shown. Only after a defined transverse displacement of the door leaf 1 - which is attached to the guide arm 6 guide pin 8 has moved a bit along the bent portion 7a of the stationary guide plate 7 - passes the arranged on the angle lever 20 guide roller 22 out of engagement with the control plate 18 and the on the guide arm 6 fixed guide roller 9 in engagement with the Curved track of the control plate 19. During the further movement of the door leaf 1, the required motive force is transmitted exclusively via the guide unit 17. In the lower region of the rotary column 5, a pivot lever 23 is attached to this, whose guide rollers 24, engage around the lower guide rail 4 of the door leaf 1 (FIG. Fig. 5 ). The movement of the angle lever 20 is synchronously transmitted via the rotary column 5 to the lower pivot lever 23.

The operation of the proposed support guide is described below with reference to the Fig. 6 explained.

The figure a shows the door leaf 1 in the closed position.

The pivotally mounted in the vertical axis 28 guide tube 26 which is guided with its protruding end in the arranged on the door frame side guide 2 37, located in a pivoted position. The slidably mounted on the guide tube 26 sleeve 29 is located at the outer end of the guide tube 26, in the starting position.

With the triggering of the command "door open" the door leaf 1 is unlocked in the region of the vertical locking edge and offset by motor 10 and transmission of the tensioned between the rollers 13,14 timing belt 15 in motion. The door leaf 1 is pushed out of the door opening in the transverse direction and assumes a skew, as shown in Figure b. During this movement, the guide arm 6 and the bush 30 connected thereto moved along the sleeve 29 a piece in the x direction, while the guide tube 26 a piece outwardly, in the y direction, pivoted and the socket 30 slightly to its vertical Axis 32, counterclockwise, rotated so that the longitudinal center axes of the sleeve 29 and socket 30 are now in a vertical plane.

With the further circular arc-shaped movement of the guide arm 6, the upwardly projecting guide pin 8 is still in engagement with the curved guide 7a of the stationary plate 7, the door leaf 1 is moved to the displacement position, which runs parallel to the car outer contour in the present example. In this case, the guide arm 6 and the socket 30 connected thereto continue to move along the sleeve 29, in the x-direction, and the guide tube 26 is pivoted and locked in a position parallel to the door leaf 1, in the y-direction (Figure c). The guide pin 8 of the guide arm 6 is now no longer in engagement with the curved guide 7a.

During the further displacement movement of the door leaf 1 along the Fahrzeugau- ßenkontur, in the x direction, the socket 30 coupled to the sleeve 29 (the lugs 34 engage in the recesses 35), so that now sitting on the guide tube 26 sleeve 29 in x direction is moved or pulled (Figure d).

Figure e shows the door leaf 1 in the fully open position, in which the sleeve 29 is moved to the holder 27.

The closing movement of the door leaf 1 takes place in the reverse order, with the beginning of the closing movement, a coupling between the sleeve 30 and sleeve 29 via the aforementioned coupling element and thereby the sleeve 29 is pulled back into its original position. When the sleeve 29 has reached its initial position again, the coupling connection is released, and guided on the sleeve 29 bushing 30 is moved to its original position and thereby pivoted clockwise about the vertical axis 32. After completion of the closing movement of the door panel 1, the support guide assumes the position shown in Figure a.

The proposed carrying guide has the advantage that it is suitable for suspension and stabilization of the door leaf for different applications, such as single or double-leaf doors, even with separate movements of the individual door leaves, or for so-called "special doors".

For a manufacturer of rail vehicle doors, it is of great advantage if a large number of identical components can be used for different door variants.

In the FIGS. 7 and 8th is still a variant for a two-leaf "special door" shown in the vehicle by the door leaves 1, 1 'in the open state do not take parallel to the car outer contour extending position, the two support guides 25 and 25' are arranged in mirror image. Due to the changed course of movement of the door leaves 1, 1 'have the curved guides 7a, 7a' in the stationary plates 7 and 7 'a different contour course. In these two figures, identical components are identified by the same reference numerals. The left door leaf 1 '- seen from the entry side - associated components are provided with a superscript. Each door leaf 1, 1 'is assigned a carrying guide 25 or 25'. In contrast to a single-leaf door, the horizontal guides 37 and 37 'for the respective guide tube 26, 26' are in the region of the center of the door opening. For this purpose, in the upper region of the car body, in the middle, a stable holder 36 is arranged, on which the horizontal guides 37, 37 'for the guide tubes 26, 26' and the required locking 38 are arranged. The lock 38 is designed as a pivot lever which simultaneously locks both guide tubes 26, 26 '. Due to the predetermined sequence of movements for the door leaves 1, 1 ', the guide tubes 26 and 26' pivot further than in a support guide for single-leaf sliding sliding doors. The operation of the two door leaves 1, 1 'and the support guides 25, 25' is analogous to the previously explained single-leaf door. For special doors, lets it not always realize that the carrying guide lies within the portal width, which is the case in this example.
