Description

The invention is directed to a guiding and locking device of a sliding door system of a vehicle, in particular a passenger transport vehicle, which comprises a guided at one end to an associated door leaf of a door pivot lever which is secured at its other end to a locking element which in an am Door frame and / or stationary on the vehicle floor arranged guide and locking part is pivotally mounted. Furthermore, the invention is directed to a passenger transport vehicle having a pivoting sliding door system with a guiding and locking device, wherein the guiding and locking device comprises a guided at one end to an associated door leaf of a door pivot lever which is fastened with its other end to a locking element is, which is pivotally mounted in a fixedly arranged on the door frame and / or on the vehicle floor guide and locking part.

Guiding and locking devices of swing door systems for passenger vehicles are known in the art. They ensure that in the case of single or double-leaf sliding sliding doors, the door leaves are flush with the vehicle outer wall when closed and that when opening the door leaves, the door leaves are moved out of the door opening along a curved and curved path and then along the vehicle outer wall.

The necessary components of such sliding door systems are generally cantilever and extendable components, which are often arranged disturbing in the door opening and must be provided with a panel.

From the DE 199 46 501 A1 For example, a sliding door system is known in which a door leaf of a door leaf is slidably mounted on a horizontal support rod of a storage unit above the door opening, wherein the storage unit is extendable from the door opening perpendicular to the direction of displacement of the door leaf. The door leaf is moved by means of a arranged above the door opening drive device when extending and retracting from or into the door opening by means of a mechanical control that allows a lock with the door closed, pivoting sliding manner. In this way, the door leaf is guided, moved and locked at its upper side edge. To guide the movement of the lower side edge of the door leaf, a door tree tube is articulated via an angle mechanism driven by the drive device and cooperates with a swivel cylinder arranged in the floor area next to the door opening. The pivot cylinder engages via a pivot arm in such a way in the door leaf, that the lower side edge is guided approximately synchronously with the upper side edge of the door leaf. Thus, the locking of the door leaf takes place only by constructive measures within the drive device to prevent accidental opening of the door panel. A locking mechanism that locks the door leaf at its lower side edge is not provided.

A sliding door system is further from the EP 0 936 119 A1 known in which the locking mechanism not as Part of the drive device, but is designed in the form of a hook which is provided at half door leaf height in the region of the minor closing edge of the door leaf and is movable by rotation of the Türbaumrohres such that the door leaf is released or locked. With this construction, however, it is possible that during the closing movement of the door leaf, this is guided in such a tilted manner that the hook, which is not permanently connected to the door leaf, engages in "emptiness" and thus locking can not take place.

A generic guide and locking device of a sliding door system is from the DE 10 2004 045 072 A1 known in which a door leaf is articulated in the vicinity of the secondary closing edge on a door tree pipe. The Türbaumrohr has a pivot lever for connection to the door leaf, wherein upon rotation of the Türbaumrohrs a finger is placed in the region of the minor closing edge of the door leaf, so that when the door leaf is closed by the finger, the movement of the door leaf is blocked in the direction of the vehicle longitudinal axis.

In the above-mentioned sliding door systems for locking the door leaf by means of a mechanism provided outside of the drive device, a door boom arranged disturbingly in the region of the door opening is a necessary component of the system. The Türbaumrohr required for storage additional components and takes a not inconsiderable installation space, so that sliding door systems with a Türbaumrohr of operators of passenger vehicles are reluctant to be used.

Solutions for locking a door leaf without using a Türbaumrohrs are known from the prior art. However, these swing door systems for locking at the lower side edge of the door leaf of the door leaf or at half the door leaf height locking mechanisms are provided which require an additional drive device, such as a pneumatic or electric drive. For example, from the DE 2 140 793 A1 a sliding door system with a locking mechanism for external sliding doors known. The locking mechanism is in this case arranged at half the height of the door leaf and has a hook system which uses a force source, ie a motor, provided for locking purposes. Such sliding door systems with additional power source in the form of an engine are highly unpopular because of their complex and expensive designs for locking the door panel in the operators of passenger vehicles.
The US 3683 552 discloses a guiding and locking device having the features of the preamble of claim 1.

There is thus a need to provide a guiding and locking device which at least in addition to a formed as part of the pivoting movement of a door actuator drive mechanism locking mechanism, the door leaf on one of the drive device of the door leaf opposite side edge self-locking and self-locking, without the addition of an additional Drive or a Türbaumrohr is required.

The invention is therefore an object of the invention to provide a solution that allows a simple design and inexpensive secure locking a door panel.

In a guiding and locking device of the type described, this object is achieved by the features of claim 1.

Likewise, the above object is achieved by a passenger transport vehicle having a guiding and locking device according to one of claims 1 to 8.

Advantageous and expedient refinements and developments of the invention will become apparent from the corresponding dependent claims.

The inventive guide and locking device a perfect separation between the lower door leaf guide and the upper door leaf guide is achieved, being combined in an advantageous and simple way, the lower door leaf guide with a door lock. The guide and locking device according to the invention requires no directly coupled to the drive device of the door leaf connecting or deflecting parts to safely guide the door leaf at the lower side edge when opening and ensure a firm grip of the door panel when locking. In particular, a disturbing arranged in the door opening door boom pipe is no longer required. This leads to significant space and weight savings of the entire sliding door system and to a reduction in manufacturing costs. Also, no additional drive mechanisms in the form of motors for locking the door leaf are necessary to arrange the disturbing in the door opening and beyond would be provided with a fairing. In addition, the guiding and locking device can be integrated as a highly compact assembly in the door frame of the door opening.

In order to ensure a secure and firm hold of the guiding and locking device in its locking position, the invention provides that the first gate opening has a locking area and the sliding block has a locking portion, which engage in the locking position of the guiding and locking device with each other. In the case of locking region engaged in the locking region, this has the advantage that, in the case of a force acting transversely to the direction of the vehicle longitudinal axis, no force component acts on the guiding and locking device which could cause disengagement of the locking section from the locking region. In addition, a disengagement from the locking portion in the longitudinal direction of the vehicle is not possible because the upper-side drive mechanism holds the door in its closed position.

In the invention, the movement effect of the moving of the drive device door leaf is transferred to the pivot lever and from this on the slide link, so that a structurally easy to implement possibility of a compact design of the guide and locking device, which releases the lock and pivoting is possible , in that the pivot lever during the opening operation of the door leaf displaces or pulls the locking portion of the sliding block slide out of the locking area of the first slot opening and pivots relative thereto.

During the closing process of the door leaf, the pivot lever pivots the locking portion of the sliding block slide in front of the locking area the first gate opening and according to the invention the Verriegelungsabschitt in this, so that a secure and firm grip of the door leaf is ensured during its locking.

To reduce the installation space and the compact design of the guiding and locking device, it pulls or pushes advantage that the link opening has the locking area and a pivoting area, so that the opening operation and the locking of the door panel can be realized by means of only one component.

The locking portion of the sliding block slide is designed in the form of a latching lug. This makes it possible that the locking and pivoting of the link element is realized solely by a component, namely the sliding block with locking lug. Thus, forces acting perpendicular to the vehicle longitudinal axis, which occur for example when passengers abut against the door leaf, disengage the locking lug from the locking portion of the first link opening and a movement of the door in the direction transverse to the vehicle longitudinal axis does not cause.

When mounted in the upper region of the door opening on a drive device door leaf, it is also advantageous if the guide and locking part is arranged on the bottom side of the door frame, so that the door leaf is securely locked in the locked position over its entire height.

An inexpensive and structurally simple way by which the door leaf can be moved by means of the guiding and locking device pivoting sliding manner in an optimally interpretable, curved movement path, so that only a small space requirement is required when opening and closing the door leaf, is that the pivot lever is a roller pivot lever, in particular a double roller pivot lever is. It is further advantageous if the pivot lever has a running in a door-side guide roller, preferably a pair of rollers running therein.

In order to increase the structural stability of the guiding and locking device and thus the sliding block can be safely guided in the vehicle longitudinal direction, the invention further provides that the guiding and locking part, a second guide element formed therein second link opening in the form of a groove or a slot in which / which engages a guide portion of the slotted link and in which / which it is guided displaceably in the vehicle longitudinal direction.

To further increase the compactness of the guiding and locking device, the invention provides in an embodiment that the first guide element and the second guide element integrally formed or rotatably connected to each other by means of pinning, screwing or welding. The one-piece design of these two guide elements, it is possible that this one-piece component can be produced in a single manufacturing process, so that reduce the total cost of manufacture.

In order to install the guide and locking device as a complete and compact unit easy to maintain and replace when necessary in case of wear, it is also advantageous if the first guide element and / or the second guide element are mounted by means of a support plate on the door frame.

In a further embodiment of the invention, it is provided that the first guide element and / or the second guide element are mounted non-rotatably on the support plate. By at least one of the two guide member rotatably mounted on the support plate, eliminates a rotationally fixed attachment of the other guide member to the support plate, when both guide elements are rotatably connected to each other, so that disassembly and replacement of the guiding and locking device of the support plate and on easily easy way by disassembling only one of the two guide element possible.

The Fig. 1 shows a sliding door system of a passenger transport vehicle not shown with two door leaves 27 which close a door opening 2. However, the guide and locking device explained in detail below is not limited to such a two-wing pivot sliding door system, but can also be used in single-leaf, ie only a door leaf 27 having sliding door systems. Each door leaf 27 is in its upper region of the door opening 2 via brackets 3 to in Fig. 1 not shown supporting rods slidably mounted. Further, in the upper area of the door opening 2 an in Fig. 1 only schematically illustrated drive device 4 is arranged, which drives and moves the door leaf 27 for opening and closing the door opening 2 and during its displacement along a vehicle outer wall 5.

The guide and locking device has per door leaf 27 on a guide and locking part 6, which is assigned in each case one on the vehicle interior facing side on the respective door leaf 27 arranged door leaf 1. In the exemplary embodiment, per door leaf 1 on the bottom side, in each case a guide and locking part 6 is attached to the door frame 7 at the level of a lower side edge of the left or right door leaf 1. It is also conceivable, the guide and locking part 6 at any height of the door leaf 1 on the door frame 7, only to be arranged on the vehicle floor 8 or the door frame 7 and vehicle floor 8, where it is for reasons of installation and in terms of effective Verregelung of each associated door leaf 1 at the top of the door opening 2 attached drive device 4 appears appropriate to arrange the guide and locking part 6 in the region of the vehicle floor 8.

That in the Figures 2 and 5 Guide and locking member 6 shown comprises a first guide member 9, a second guide member 10 and a third guide member 11, each formed as a plate-shaped member and are arranged one above the other, wherein the first guide member 9 sandwiched between the second guide member 10 and the third guide member 11 is. A locking element designed as a sliding block 12 is formed in a first gate opening 14 in the first guide element 9 and in a respectively in the second and third guide element 10 and 11 formed second and third gate opening 15a, 15b used. Since the third guide element 11 is identical to the second guide element 10, is only in Fig. 4 the second guide element 10 is shown. Because of in the Figures 2 and 5 shown assembly position of the guiding and locking device, the sliding block 12 can not be seen in these figures.

In the first guide member 9 is a in the FIGS. 7 and 8th illustrated first gate opening 14 is formed, which has a locking portion 16 and a Verschwenkungsbereich 17, in which the sliding block 12 is slidably and pivotally guided. In the second and third gate opening 15 a, 15 b, each formed in the second and third guide member 10 and 11 and of which by way of example in Fig. 4 only the gate opening 15a of the second guide member 10 is shown, engage in detail below described guide portions 12a, 12c of the sliding block 12, whereby the sliding block 12 is slidably held in the vehicle longitudinal direction in the second and third gate opening 15a, 15b. This longitudinal displacement is achieved in that the slide openings 15a, 15b are formed in the form of elongated holes and the guide sections 12a, 12c form cylinders guided therein.

The in Fig. 3 12 shown sliding cam 12 is a substantially cylindrical member with each formed at its ends guide portions 12a, 12c and an interposed sliding block section 12d, which has a larger diameter than the guide portions 12a and 12c and a laterally projecting locking portion 12b in the form of a latch 13. The latch 13 is in the in Fig. 7 illustrated locking position of the first Guide element 9 and slide cam 12 and thus the guide and locking device in the locking portion 16 of the first gate opening 14 is engaged and engaged with this. In the in Fig. 8 illustrated opening position of the door panel 1, the latching lug 13 is disengaged from the locking portion 16 of the first link opening 14 and arranged pivoted in the Verschwenkungsbereich 17 in the direction of the vehicle outer side.

The second and the third guide element 10, 11 each have the second and third gate opening 15a, 15b, which are each formed in the embodiment as a slot. The slotted openings 15a, 15b serve to guide the sliding block slide 12 in the vehicle longitudinal direction, wherein the width of the respective oblong hole substantially corresponds to the diameter of the guide sections 12a, 12c. In each slot of the second and third guide element 10 and 11 engages in each case a guide portion 12a, 12c, so that the slide block 12 is held displaceably with one of its two ends in the second and third guide member 10 and 11. Instead of oblong holes, the slide openings 15a, 15b may also be formed in each case as a groove, in which case the respective end of the sliding block slide 12 is displaceably guided in an associated groove. The third guide element 11 is optional and serves only to reinforce the structural structure of the guiding and locking part 6. It can therefore also be omitted, so that it is also conceivable to form the first and the second guide member 9 and 10 in one piece to achieve an increase in compactness. Alternatively, the Verschwenkungsbereich 17 of the first gate opening 14 sections serve as a guide of the sliding block 12 by a section of a in the FIGS. 7 and 8th illustrated stop edge 18 is formed into a portion of a slot in which the sliding gate section 12d is guided, so that the second guide element 10 can be omitted. Such an embodiment is in the FIGS. 9 and 10 shown.

The guide elements 9, 10 and 11 are mounted on a support plate 19 on a door frame 27 laterally and framing on its upper side door frame 7. It is sufficient if at least one of the guide elements 9, 10 or 11 rotatably connected to a arranged on the door frame 7 support plate 19, since the guide elements 9, 10 and 11 by means of pinning, screwing, welding or the like rotatably connected to each other. The support plate 19 is also an optional component, which can be dispensed with, if at least one of the guide elements 9, 10 and 11 is rotatably connected directly to the door frame 7.

A per se known pivot lever 20 is shown schematically in the FIGS. 7 and 8th and more detailed in Fig. 6 shown in top view on its underside. It has at its one end a mounting opening 28, in which engages in the assembled state of the guiding and locking device of the slide slide 12 with its guide portion 12a. The guide portion 12a is rotatably connected to the pivot lever 20. Alternatively, the pivot lever 20 may be rotatably connected to the guide portion 12c. At its other end, the pivot lever 20 has two further openings 28, in each of which a roller 21 is rotatably mounted, so that it is at the pivot lever 20 is a double roller pivot lever. The pivot lever 20 is arranged in the embodiment below the second guide member 10, as shown in the Figures 2 and 5 is apparent. The two rotatably mounted in a respective associated opening 29 rollers 21a, 21b of the in the FIGS. 7 and 8th only schematically illustrated pivot lever 20 are inserted into a guide rail 22 arranged in the door leaf 27, which comprises a disengagement section 23, a bent and angled section 24 and a displacement section 25.

The operation of the guiding and locking device will be described below with reference to FIGS. 7 and 8th explained. For the sake of clarity is in the FIGS. 7 and 8th only the first guide member 7 of the guide and locking member 6 with arranged therein guide portion 12c and slide cam portion 12d of the slide block 12 is shown.

The Fig. 7 shows the guide and locking device in its locking position with the door closed 27. In this position, the pair of rollers 21a, 21b of the pivot lever 20 is located at its end position on the guide rail 22, wherein the roller 21b on the door frame 7 facing side surface of the Ausrückabschnitts 23 abuts , The locking lug 13 of the sliding block 12 is engaged in the locking portion 16 of the first guide member 9, so that a rotational movement of the sliding block 12 and the rotatably mounted pivot lever 20 is not possible. Due to the active connection between the sliding block slide 12 and the door leaf 27 moved by the drive device 4, it is held in the locking position by the sliding block 12 and stabilized in its closed position in the area of the vehicle floor 8. Vertical forces occurring perpendicular to the vehicle longitudinal axis, which occur at pressure differences and when abutting passengers on the door leaf 27, can Release or disengagement of the detent 13 from the locking portion 16 does not cause.

When opening and closing the door leaf 27 standing in operative connection with the sliding block 12 door leaf 1 is moved by the drive device 4 schwenkschiebeartig. The movement of the door leaf 1 caused by the drive device 4 and thus also its lower section is in Fig. 7 indicated by the curve 26. In carrying out one of the in Fig. 7 in a first step of the door leaf 27 of the drive device 4, as indicated by the portion 26a of the curve 26, laterally moved parallel to the vehicle longitudinal axis in the vehicle longitudinal direction. This movement is transmitted from the door leaf 27 to the disengagement section 23 of the guide rail 22, which then moves the roller 21b resting against it, which transmits this movement, which is parallel to the vehicle longitudinal axis, to the sliding block 12 by means of the pivoting lever 20. As a result, the locking portion 12b and thus the locking lug 13 of the rotationally fixed to the pivot lever 20 arranged sliding block slide 12 in the direction of the arrow 30 from the locking portion 16 out and thus leave the caused by the guiding and locking part 6 locking position. To stabilize and precise guidance of this movement, the sliding block slide 12 is thereby guided in the respective slot openings 15a and 15b of the second and third guide elements 10 and 11. In this first step of the opening movement in the direction of the door frame 7, ie in the vehicle longitudinal direction, that is, the latching lug 13 is disengaged from the latching area 16 of the first guide element 9. This is then the locking of the sliding block 12 lifted in the first guide member 9, so that the sliding block 12 can now be pivoted by the pivot lever 20 in the pivoting region 17 in the direction of the vehicle outer side.

Following the pushing out of the locking lug 13 from the locking portion 16 causing disengagement movement of the sliding block 12 is in an in Fig. 8 shown second step of the door leaf 27 in a direction indicated by the portion 26b of the curve 26 curved or curved trajectory from the door opening 2 to the door frame 7 around the vehicle outside and before and along the / the vehicle outer wall 5 moves. This movement is in turn effected by the drive device 4 and transmitted from the door leaf 27 on the guide rail 22 and from there via the rollers 21 a, 21 b resting thereon on the cam slider 12 which is connected in a rotationally fixed manner to the pivot lever 20. This is thereby pivoted in the direction of the arrow 31 in the Verschwenkungsbereich 17 in the direction of the vehicle outside. In this case, the locking portion 12b and the guide portion 12d abut the opening edge of Verschwenkungsbereichs 17 of the first gate opening 14 and slide along it during the pivotal movement of the sliding gate until the locking lug 13 abuts in the end position of the pivoting movement on a stop edge 18 of the pivoting portion 17. In this case, the rollers 21a, 21b running in the guide rail 22 follow the curved or arcuate opening and swiveling movement of the door leaf 27 in its lower region, by moving along the section 24 in the direction of the displacement section 25 of the guide rail 22.

When the two rollers 21a, 21b have reached the end of the angled and bent portion 24, they then run in a third step along the rectilinear displacement section 25, when the door leaf 27 is moved along the vehicle outer wall 5 and reaches its open position, in which the door opening 2 is released for the exit / entry of persons. This movement is also effected by the drive device 4 arranged in the upper region of the door opening 2 and transmitted to the lower side of the door leaf 27. During their movement along the displacement section 25 corresponding to the section 26c of the curve 26, the rollers 21a, 21b hold by means of the fixed and stiff pivoting lever 20 and due to the sliding block 12 in the first gate opening 14 and in the second and third gate opening 15a, 15b Guide, locking and sliding gate sections 12a, 12b, 12c and 12d the door leaf 27 in the in Fig. 8 shown distance to the vehicle outer wall. 5

The closing of the door leaf 27 then takes place in the reverse order of the three steps explained above. Due to the lateral and arcuate movement of the door leaf 27 generated by the drive device 4 in the upper region of the door opening 2, the rollers 21a, 21b run along the displacement section 25 in the direction of the bent and angled section 24 of the guide rail 22 and follow the curved section 26b corresponding to the curved section This pivoting movement is transmitted via the pivot lever 20 on the sliding block 12, so that it is rotated in the counterclockwise direction and indicated by the arrow 31 direction of movement until the locking lug 13 of the sliding block 12 reaches the locking portion 16 and in the direction of Locking portion 16 of the first guide member 9 has. Thus, the locking portion 12 b has been pivoted in front of the locking portion 16. Upon further movement of the door leaf 27 in the vehicle longitudinal direction of the disengagement section 23 comes into contact with the roller 21a, so that as a result of further movement in the direction of the cam portion 26a of the pivot lever 20 and the rotatably mounted on this slide cam 12 are moved perpendicular to the door frame 7 in the vehicle longitudinal direction and thus the latch 13th is pulled into the locking portion 16, whereby the door leaf 27 is blocked or locked by the thus achieved locking position of the guide and locking part 6.

A more compact construction of the guiding and locking device can be achieved by modifying the first guide element 9 and the locking element 12 designed as a locking element. Such an embodiment with modified first guide member 32 and modified slide block 33 is in the FIGS. 9 and 10 shown. In the first guide member 32, a modified first gate opening 34 is formed, which has the locking portion 16 and a modified Verschwenkungsbereich 35. The trained in Verschwenkungsbereich 35 stop edge 18 is used in sections as a guide of the modified sliding block 33 by a portion 36 of the stop edge 18 is parallel to the opposite edge 37 of the gate opening 34 is formed. The displacement of the slide in the vehicle longitudinal direction during the opening process is limited by a circular arc-shaped portion 38 which connects the portion 36 and the portion 36 opposite edge 37 together. The width of this section of the guide serving in the vehicle longitudinal direction substantially corresponds to the diameter of the sliding block slide section 12d, so that the sliding block slide 33 is longitudinally displaceable within this section in the vehicle longitudinal direction and can also be guided pivotally, as soon as the latching lug 13 of the sliding block 33 is disengaged from the locking area 16 of the first guide element 32. Since the first guide element 32 additionally serves in this embodiment the guide of the sliding block slide 33, the second and third guide elements 10, 11 are superfluous and therefore omitted. Thus, also formed on the sliding block 12 guide portions 12a and 12c are no longer necessary, so that the modified slide block 33 has only one mounting portion 39 which engages in the mounting opening 28 of the pivot lever 20 such that the pivot lever 20 and the sliding block 33 rotatably connected to each other are. Apart from the aspect that the sliding block 33 is now guided exclusively by means of the modified first guide element 32, the operation of this embodiment is unchanged, so that reference is made to the above-described operation of the guiding and locking device.
