Description

The The invention relates to a sliding door for a vehicle with at least one Door panel, the above at least one in a leadership of the door leaf slidably guided Ausschwenkhebel rotatably connected to a vehicle-fixed frame is and further by means of at least one further pivot lever in a vehicle-mounted main tour guided is in accordance with the preamble of Patent claim 1.

A generic sliding door is from the DE 43 16 253 A1 known. In this known device, the pivot lever is moved via a guide arm by the reaction torque of the drive housing in the issued position and held there by means of two, forming a parallelogram lever. The holder via the pivoting lever and the guide arm is relatively unstable when the drive is not active.

Another sliding door is out of the DE 1 480 604 C known. In this known door, the pivoting movement of the door is separated from the sliding movement. There are separate drives for the pan and the sliding movement provided or an additional locking device ensures a separation of both movements.

It The object of the present invention is to provide a sliding sliding door, in the case of a continuous, sliding movement from the closed position in the opening position and stable positioning in the end positions is made possible.

These The object is achieved by the solved in claim 1 means. Advantageous embodiments The invention can be found in the dependent claims.

Thereby, that the Swing lever with the swivel lever over a distance of both Lever steadily controlling device is connected by means of a single drive is driven, is a continuous, jerk-free activity the sliding door achieved, combined with a cost-effective design due the omission of a second drive or an additional Locking device. Due to the fact that the pivot lever by means of a on a longitudinal main guide slidably mounted drive carriage during an opening or closing movement is continuously driven and characterized in that the pivot lever further preferably with an additional Push rod transmission is connected, which is guided in an auxiliary guide push rod comprises their end with the leadership on the door leaf additionally engaged, results over the push rod transmission has a continuous sliding opening and closing movement. With a continuous movement is not in the above sense meant that the Drive must be at a constant speed; much more allows just the sliding door according to the invention a stepless Speed control, for example, in the form of a reduced Speed in the end area when closing for a current detection to avoid the Pinching of body parts or objects extremely useful can be used. Due to the smooth sliding transition from a rotational-translatory in a translational movement is the reliability of operation and significantly increases the service life of the sliding door.

According to one first embodiment variant includes the device a push rod transmission with two scissors-connected at a hinge point Push rods, wherein the hinge point is guided in the auxiliary guide.

Advantageous is a first push rod with the pivot lever in a hinge point connected, the longitudinal an additional one inner guidance slidably guided is. The term inner guidance means that this with respect to a central longitudinal axis of the vehicle is located furthest inside.

Especially good kinematic conditions result by the fact that the coupled with the pivot lever first push rod is shorter as one with the leadership on the door leaf engaged second push rod.

According to one second embodiment it is advantageous if the device as a push rod transmission includes two push rods, the at two spaced hinge points on a displaceable on the auxiliary guide mounted sliding element are articulated. In this further embodiment can the first push rod immediately with a one piece on Drive carriage provided pivot lever be coupled and the Inner guidance can be omitted.

at both embodiments it is advantageous if the auxiliary guide is the main guide in as seen from the vertical projection. It is for the kinematics turn particularly advantageous if the intersection S of the auxiliary guide and the main tour with closed door leaf about in height the middle of the same is arranged.

A especially soft sliding opening and closing closing movement results from the fact that the auxiliary guide a S-shaped curvature having.

Of the Drive of the drive carriage is preferably via a Traction mechanism - like a flat belt, V-belt or toothed belt.

Finally is it for a safe support of the door leaf advantageous when using the door leaf in Engaging push rod and the engaging with the door leaf End of the Ausschwenkhebels on a common, in the leadership of the door leaf sliding slider are hinged pivotally.

following are two embodiments of Invention described with reference to the drawings. It shows:

1 a perspective view of the upper actuating mechanism of a sliding door in the closed state,

2 a representation according to 1 with open sliding door,

3 a representation according to 2 omitting the vehicle-fixed frame parts,

4 in plan view, a representation of the relevant for the movement of the door parts in the closed position,

5 a representation according to 4 with partly open door,

6 a representation according to 4 with the door completely open,

7 the parts essential to the kinematics of a second embodiment with the door closed,

8th a representation according to 7 with partly open door and

9 a representation according to 7 with completely open door.

In the 1 partially shown sliding door covers with its door leaf 2 in the closed position, a door opening 23 in a side wall of a vehicle - preferably a bus - from. 1 illustrates a perspective view from above of the upper bracket and the actuating mechanism of a door leaf 2 , It is understood that two mirror-symmetrically arranged door leaves 2 can be combined to a double swing door. This preferably has two mirror-symmetrically arranged actuating mechanisms, which are actuated by means of a single centrally disposed drive.

With the vehicle, in the example with the bus, a generally designated 1 frame is firmly connected, which consists of an upper frame part 1A a parallel thereto at a distance below the same arranged lower frame part 1B and between these arranged, connecting the two frame members braces 1C composed.

On the frame 1 is a warehouse part 20 provided, which for the storage of a vertically arranged rotary column 4 serves. At this turning column 4 is rotatably a Ausschwenkhebel 3 attached. The pivot lever 3 has a bent shape and stands with its free end 3A engaged with one at the top of the door panel 2 provided guidance 18 ,

The door leaf 2 is also near its leading edge - ie in 1 the visible edge in the lower left part - in the form of a swivel joint 5A with a swivel lever 5 connected. The swivel lever 5 is in a joint 5B on a drive carriage 6 pivotally hinged, which on a substantially parallel to the position of the door leaf 2 arranged main guidance 7 is guided longitudinally displaceable. The swivel lever 5 is also in the form of a joint with its inner end 5C on a sliding element 12 pivotally hinged, which at an angle to the main guide 7 running inner leadership 13 is guided longitudinally displaceable.

At the pivot point 5C is also a first push rod 14 pivotally hinged, which at its other end in a hinge point 15 with a second push rod 16 is connected and forms a scissor-shaped push rod transmission with this. The pivot point 15 is in one of the frame 1 arranged, S-shaped curved auxiliary guide 17 guided smoothly.

The drive carriage 6 is via a traction drive with a motor 11 connected to a bracket 21 is flanged, which is mounted near the rotary column 4 on the frame and a reduction and deflection gear to a drive pinion 10 includes. As a pulling means in the present case, a belt 8th used, which is executed in the example as a flat belt, but can also be alternatively designed as V-belt or timing belt. The belt 8th gets over that near the spin column 4 arranged drive pinion 10 driven and via a pulley 9 deflected, located on the opposite side of the frame 1 near the front edge of the door in closed position. The drive carriage 6 is with the belt 8th connected, so that its tensile forces a displacement of the drive carriage 6 along the main tour 7 cause.

The opened position of the door leaf 2 is in 2 clarified. This was the drive slide 6 by means of the belt 8th from the position in 1 moved to a position near the rear end of the door opening 23 located. The same position is still in 3 shown here, where here all the view obscuring parts of the frame 1 have been omitted, thereby engaging the Ausschwenkhebels 3 , the pivot lever 5 and the second push rod 16 in the lead 18 of the door leaf 2 better to clarify. The free outer end of the Ausschwenkhebels 3 and the outer end of the push rod 16 are together on a glider 19 pivotally hinged, in the lead 18 at the upper edge of the door leaf 2 slidably guided. From this illustration it is also apparent that the pivot lever 5 , the swing lever 3 and the second push rod 16 vertically spaced from each other slightly to overlap in the open position at least partially and thereby a nearly complete exposure of the door opening 23 to enable.

The kinematic relationships when opening and closing in the 1 to 3 shown sliding door are in the 4 to 6 shown schematically and are explained below. In the closed position according to 4 closes the door leaf 2 the door opening 23 in the sidewall 22 of the bus. The door leaf is supported by the slider 19 on the one hand with its trailing edge 2 B over the Ausschwenkhebel 3 at the turning column 4 from. On the other hand, a support via the second push rod 16 in the pivot point 16A also with the glider 19 is connected and the other end in the hinge point 15 in the auxiliary guide 17 is guided. Near the front edge 2A becomes the door leaf 2 in the hinge point 5A further by the pivot lever 5 supported, at 5B over the drive carriage 6 with the main guide 7 is connected and the at 5C over the sliding element 12 with the inner guidance 13 connected is.

The main tour 7 runs in a straight line in the first embodiment and approaches from the front edge 2A to the trailing edge 2 B the door leaf of the side wall 22 at. The auxiliary guide 17 lies in its front area near the door leaf 2 , cuts at a point of intersection S the main guide 7 and then moves away from the door leaf in the second part of the S-shaped arc 2 , where they also have the inner leadership 13 cuts. The intersection S of the auxiliary guide 17 and the main tour 7 is preferably - as out 4 visible - with closed door leaf 2 at about the middle of it.

Starting from the in 4 shown closed position is the pivot lever 5 through the in the 4 to 6 drive carriage, not shown 6 in the hinge point 5B along the main tour 7 moved to the left. Through the divergent tracks of the main guide 7 and the inner guidance 13 while doing the pivot lever 5 around the point 5B a turn clockwise through. This is at the same time the door opening approaching main guide 7 the pivot point 5A with the front edge 2A of the door leaf 2 outward from the doorway 23 pivoted.

The swivel lever 5 drives simultaneously over the joint 5C the first push rod 14 on, by the connection in the hinge point 15 a compressive force on the second push rod 16 exercises, so that this by the articulation in the joint 16A in conjunction with the support of the trailing edge 2 B of the door leaf by the Ausschwenkhebel 3 also the rear end of the door leaf 2 from the doorway 23 pivots.

The swinging out follows in a gradual, gentle movement, wherein the transition from the initially rotational and translational movement in a subsequent subsequent purely translational movement for moving the door leaf 2 in its full open position is not noticeable. In the intermediate position according to 5 is the door leaf 2 approximately half open, wherein the pivoting movement is completed and already part of the sliding movement has taken place. This is the door leaf 2 over the slider 19 from the swivel lever 3 and the second push rod 16 held and at its front edge of the pivot lever 5 driven.

In the fully open position lies the leading edge 2A of the door leaf 2 almost congruent with the trailing edge of the door opening 23 , The difference between the two positions is determined by the width of the Ausschwenkhebels 3 justified, which with its bend the side wall 22 embraces. pivoting lever 5 , first push rod 14 and second push rod 16 are arranged approximately in the form of a triangle to each other, due to the already in connection with 3 described different vertical arrangement of the three gear elements whose superimposed position in the vertical projection is possible. As a result, an almost complete opening of the door leaf 2 possible.

Due to the support on the one hand over the known Ausschwenkhebel 3 , on the other hand via the additional push rod transmission in the form of the second push rod 16 and the pivot lever 5 passing through the first push rod 14 are connected, whose two ends in the joints 15 and 5C is stably supported in guides, overall results in a particularly stable support of the door leaf 2 , also in the open position. It takes the first push rod 14 a nearly parallel position to the door leaf 2 one. By the immediate Re connection of the drive carriage 6 to the pivot lever 5 is an additional lock in both the closed and in the open position of the door leaf 2 completely dispensable.

That in the 7 to 9 clarified second embodiment has compared to the first embodiment on a modified kinematics. The same or similar components in both embodiments were provided with a reference number increased by 30. The second embodiment dispenses with an inner guide. The door leaf 32 is near its leading edge in a joint 35A with a swivel lever 35 connected, which is directly integral with the drive carriage 36 trained or rigidly connected to this. The drive carriage is along a main guide 37 led, which is a front, approximately to the door leaf 2 parallel section 37A , a subsequent curved section 37B and finally again a parallel to the door leaf extending end portion 37C having.

The drive carriage 36 is about two spaced guide pins 36A and 36B in engagement with this main guide 37 , Of course, the bolts can also be replaced by sliding elements or rollers.

In the hinge point 35A is also a first push rod 44 a push rod transmission pivotally connected to the front edge 32A of the door leaf 32 and over the rigid pivot lever 35 with the drive carriage 36 connected.

The other end of the first push rod 44 is in a pivot point 45 on a sliding element 42 pivotally hinged, which in an auxiliary guide 47 is guided longitudinally displaceable. This auxiliary guide is diagonal to the main guide 37 arranged and intersects this at an intersection S, the closed position of the door leaf 32 lying approximately at the height of the center. At the height of the trailing edge 32B of the door leaf 32 the auxiliary guidance goes 47 in an arcuate path over, which at some distance a rotary column 34 surrounds, at the Ausschwenkhebel 33 is attached. The swivel lever 33 is analogous to the first embodiment with its free end 33A with a guide 48 on the door leaf 2 in sliding engagement This intervention is preferably again by means of a slider 49 on which both the swivel lever 33 with his end 33A , as well as the outer end of a second push rod 46 are pivotally mounted, which with its inner end in a joint 46B at the skid 42 at a distance from the hinge point 45 is pivotally mounted.

In the second embodiment are also at the front edge 32A of the door leaf 32 and at the trailing edge 32B of the door leaf 32 seals 54 and 55 illustrated, which have been omitted in the first embodiment for the sake of simplicity. The seal 54 is designed so that it faces the front edge of the door opening 23 invests. The seal 55 is designed so that it with its approximately T-shaped formation with its two legs sealingly outside to the side wall 22 and on the door leaf 2 invests.

The drive of the sliding door is, as in the first embodiment, preferably by a traction mechanism, for example in the form of a belt drive. Alternatively, however, other forms of drive are conceivable, for example by means of a pneumatic or hydraulic cylinder. The motor 11 can be designed as an electric motor or, alternatively, also as a pneumatic or hydraulic motor.

When the drive carriage 36 , starting from the closed position in 7 , by means of the traction mechanism along the main guide 37 is moved to the left, it is due to the curved section 37B the main tour 37 the front edge 32A swung outwards. At the same time, the first push rod 44 driven along the auxiliary guide and thereby moves the with her on the slider 42 coupled second push rod 46 to the outside, so that also the rear end of the door leaf 32 in conjunction with the swivel lever 33 is pivoted outwards. At the same time, a translational movement of the door leaf to the rear takes place at the same time. An intermediate position in which the Ausschwenkbewegung is completed is in 8th shown. In the final position according to 9 form approximately here analogous to the first embodiment, here on the pivot lever 35 directly driven first push rod 44 , the sliding element 42 and the second push rod 46 a triangle that allows stable support of the front edge of the door leaf.
