DE19624706A1 - Hinging and sliding vehicle-door - Google Patents

Abstract

The door has one or more levers (2) swung out by a first lever (13) on the vehicle and which slides in a guide in the leaf, and guided by a second lever (5) working in a guide (7) on the vehicle. The two levers are coupled to each other by a mechanism continuously regulating the distance between them, and which is actuated by a single drive mechanism (11). The second lever can be continuously driven during opening and shutting by a slide (6) travelling along a lengthwise main guide, while also actuating a thrust-rod mechanism (14,16) with rod working in an auxiliary guide (17). One end (16A) of this rod engages in the guide (18) on the leaf.

Description

The invention relates to a pivoting sliding door for a vehicle with at least one Door leaf that is slidably guided in at least one guide of the door leaf Swing-out lever is rotatably connected to a vehicle-fixed frame and further is guided in a vehicle-fixed guide by means of at least one further pivot lever.

Such a pivoting sliding door is known from DE-C 14 80 604. In this known Door is the pivoting movement of the door separated from the sliding movement. There are separate drives are provided for the swiveling and sliding movement or one additional locking device ensures a separation of both movements.

It is an object of the present invention to provide a pivoting sliding door in which a Continuous, smooth movement from the locking system to the open position is made possible.

This object is achieved by the means specified in claim 1 solved. Advantageous embodiments of the invention can be found in the subclaims.

Characterized in that the swivel lever with the swivel lever over the distance between the two Lever continuously controlling device is connected, which can be driven by means of a single drive a continuous, jerk-free actuation of the swivel sliding door is achieved with an inexpensive design due to the elimination of a second drive or one additional locking device.

The fact that the pivot lever preferably by means of a longitudinally extending Main guide slidably mounted drive carriage during an opening or  Closing movement is continuously drivable and in that the pivot lever also is preferably connected to an additional push rod gear, one in one Auxiliary guide guided push rod includes the end with the guide on the door leaf additionally is engaged, there is a continuous sliding over the push rod gear Opening and closing movements. With a continuous movement is above The meaning does not mean that the drive must take place at a constant speed; rather, the pivoting sliding door according to the invention enables a stepless one Cruise control, for example in the form of a reduced speed in the End area when closing for current detection to avoid pinching Body parts or objects are extremely useful. Because of the gentle smooth transition from a rotational-translational to a translatory movement becomes the reliability of the operation and the lifespan of the pivoting sliding door significantly increased.

According to a first embodiment variant, the device also includes a push rod gear two push rods connected scissor-like at a hinge point, the hinge point is guided in the auxiliary guide.

A first push rod with the pivot lever in an articulation point is advantageous connected, which is guided along an additional inner guide. The term inner guidance means that this with respect to a central longitudinal axis of the vehicle is arranged furthest inside.

Particularly good kinematic conditions result from the fact that with the Swivel lever coupled first push rod is shorter than one with the guide on the door leaf in Second push rod engaged.

According to a second embodiment, it is advantageous if the device as Push rod gear comprises two push rods, which are spaced apart at two Articulation points articulated on a slidably mounted sliding element are. In this further embodiment, the first push rod can directly with a be integrally coupled to the drive slide provided pivot lever and the inner Leadership can be omitted.  

In both embodiments, it is advantageous if the auxiliary guide in the main guide seen from the vertical projection. It is again for the kinematics Particularly advantageous if the intersection S of the auxiliary guide and the main guide closed door leaf is arranged approximately at the middle of the same.

A particularly soft sliding opening and closing movement results from the fact that the Auxiliary guide has an S-shaped curvature.

The drive carriage is preferably driven via a traction mechanism gear - such as one Flat belts, V-belts or timing belts.

Finally, it is advantageous for secure support of the door leaf if the with the Door leaf engaging push rod and the end engaging with the door leaf the pivoting lever on a common, movable in the guide of the door leaf Gliders are pivoted.

. The pivot sliding door shown in Figure 1 fragmentary covers with its door leaf 2 in the closed position a door opening 23 in a side wall of a vehicle - preferably a bus - ex. Fig. 1 illustrates a perspective view from above of the upper bracket and the actuating mechanism of a door blade 2. It goes without saying that two mirror-symmetrically arranged door leaves 2 can also be combined to form a double pivoting door. This preferably has two mirror-symmetrically arranged actuating mechanisms which can be actuated by means of a single centrally arranged drive.

With the vehicle, in the example of the coach, generally designated with 1 frame is rigidly connected, which is composed of an upper frame portion 1 A, a parallel thereto at a distance below the same which is arranged lower frame part 1 B and arranged between them, both frame parts connecting struts 1 C composed.

On the frame 1 , a bearing part 20 is provided, which serves to support a vertically arranged rotating column 4 . A pivoting lever 3 is fastened in a rotationally fixed manner to this rotating column 4 . The opening lever 3 has a cranked shape and, with its free end 3 A, engages with a guide 18 provided at the upper end of the door leaf 2 .

The door leaf 2 is also in the vicinity of its front edge - that is, in FIG. 1, the edge visible in the lower left part - connected in the form of a swivel 5 A with a pivot lever 5 . The pivot lever 5 is pivotally articulated in a joint 5 B on a drive carriage 6 which is guided in a longitudinally displaceable manner on a main guide 7 arranged essentially parallel to the position of the door leaf 2 . The pivot lever 5 is also pivotally articulated with its inner end in the form of a joint 5 C on a sliding element 12 which is guided in a longitudinally displaceable manner on an inner guide 13 which runs obliquely to the main guide 7 .

At the articulation point 5 C, a first push rod 14 is also pivotably articulated, which is connected at its other end in an articulation point 15 to a second push rod 16 and forms a scissor-shaped push rod gear with it. The hinge point 15 is slidably guided in an S-shaped auxiliary guide 17 arranged on the frame 1 .

The drive carriage 6 is connected via a traction mechanism to a motor 11 which is flanged to a holder 21 which is fastened to the frame near the rotary column 4 and which comprises a reduction and deflection gear to a drive pinion 10 . In the present case, a belt 8 is used as the traction means, which in the example is designed as a flat belt, but can alternatively be designed as a V-belt or toothed belt. The belt 8 is driven via the drive pinion 10 arranged near the rotating column 4 and deflected via a pulley 9 which is located on the opposite side of the frame 1 near the front edge of the door in the closed position. The drive carriage 6 is connected to the belt 8 , so that its tensile forces cause a displacement of the drive carriage 6 along the main guide 7 .

The open position of the door leaf 2 is illustrated in Fig. 2. The drive carriage 6 was moved by means of the belt 8 from the position in FIG. 1 to a position in which it is located near the rear end of the door opening 23 . The same position is shown in FIG. 3, all parts of the frame 1 that conceal the view have been omitted in order to better illustrate the engagement of the pivoting lever 3 , the pivoting lever 5 and the second push rod 16 in the guide 18 of the door leaf 2 . The free outer end of the pivoting lever 3 and the outer end of the push rod 16 are jointly pivoted on a slider 19 which is guided in the guide 18 on the upper edge of the door leaf 2 . From this illustration it can be seen at the same time that the pivot lever 5 , the pivot lever 3 and the second push rod 16 are slightly spaced vertically from one another in order to at least partially overlap one another in the open position and thereby enable the door opening 23 to be exposed almost completely.

The kinematic relationships when opening and closing the pivoting sliding door shown in FIGS. 1 to 3 are shown schematically in FIGS. 4 to 6 and are explained below. In the closed position according to FIG. 4, the door leaf 2 closes the door opening 23 in the side wall 22 of the bus. The door leaf is supported on the one hand with its trailing edge 2 B via the swivel lever 3 on the rotating column 4 via the slider 19 . On the other hand, support is provided via the second push rod 16 , which is also connected to the slider 19 at the articulation point 16 A and the other end of which is guided in the auxiliary guide 17 at the articulation point 15 . Near the front edge 2 A, the door leaf 2 is further supported at the pivot point 5 A by the pivot lever 5 , which is connected at 5 B via the drive slide 6 to the main guide 7 and which is connected at 5 C via the sliding element 12 to the inner guide 13 .

In the first exemplary embodiment, the main guide 7 runs in a straight line and approaches the side wall 22 from the front edge 2 A to the rear edge 2 B of the door leaf. The auxiliary guide 17 lies in its front area near the door leaf 2 , cuts the main guide 7 at an intersection S and then moves further away from the door leaf 2 in the second part of the S-shaped arc, where it additionally cuts the inner guide 13 . The intersection S of the auxiliary guide 17 and the main guide 7 is preferably - as can be seen in FIG. 4 - when the door leaf 2 is closed, approximately at the center of the same.

Starting from the closed position shown in FIG. 4, the pivot lever 5 is moved to the left along the main guide 7 by the drive slide 6, not shown in FIGS. 4 to 6, at the articulation point 5 B. Due to the diverging paths of the main guide 7 and the inner guide 13 while the pivot lever 5 5 B leads to the point in rotation by a clockwise direction. In this way, the door opening approximate main guide 7 is pivoted to the pivot point 5 A with the leading edge 2A of the door leaf 2 to the outside of the door opening 23 simultaneously with him.

The pivot lever 5 simultaneously drives the first push rod 14 via the joint 5 C, which exerts a compressive force on the second push rod 16 through the connection at the articulation point 15 , so that the second push rod 16 by the articulation in the joint 16 A in connection with the support of the rear edge 2 B of the door leaf also pivots the rear end of the door leaf 2 out of the door opening 23 by means of the pivoting lever 3 .

The swiveling out follows in a gradual, gentle movement, the transition from the initially rotary and translatory movement into a subsequent subsequent purely translatory movement for moving the door leaf 2 into its full open position not being felt. In the intermediate position according to FIG. 5, the door leaf 2 is approximately half open, the pivoting movement being completely completed and part of the sliding movement having already taken place. In this case, the door leaf 2 is held by the swivel lever 3 and the second push rod 16 via the slider 19 and driven by the swivel lever 5 on its front edge.

In the fully open position, the front edge 2 A of the door leaf 2 is almost congruent with the rear edge of the door opening 23 . The difference between the two positions is justified by the width of the pivoting lever 3 , which bends around the side wall 22 . Swivel lever 5 , first push rod 14 and second push rod 16 are arranged approximately in the form of a triangle with respect to one another, the superimposed position in the vertical projection being possible due to the different vertical arrangement of the three gear elements already described in connection with FIG. 3. This enables the door leaf 2 to be opened almost completely.

Because of the support on the one hand via the known pivoting lever 3 , on the other hand via the additional push rod gear in the form of the second push rod 16 and the pivot lever 5 , which are connected by the first push rod 14 , the two ends of which in the joints 15 and 5 C in Guides is supported stably, there is a particularly stable support of the door leaf 2 , even in the open position. The first push rod 14 assumes an almost parallel position to the door leaf 2 . The direct connection of the drive carriage 6 to the swivel lever 5 makes an additional locking both in the closed and in the open position of the door leaf 2 completely unnecessary.

The second exemplary embodiment illustrated in FIGS . 7 to 9 has modified kinematics compared to the first exemplary embodiment. Identical or similar components in both embodiments have been provided with a reference number increased by 30. The second embodiment dispenses with an internal guide. The door leaf 32 is connected near its front edge in a hinge 35 A to a pivot lever 35 which is formed directly in one piece with the drive slide 36 or is rigidly connected to it. The drive carriage is guided along a main guide 37 , which has a front section 37 A, approximately parallel to the door leaf 2 , an adjoining curved section 37 B and finally an end section 37 C running parallel to the door leaf.

The drive carriage 36 is in engagement with this main guide 37 via two spaced-apart guide bolts 36 A and 36 B. The bolts can of course also be replaced by sliding elements or rollers.

At the pivot point 35 A, a first push rod 44 of a push rod gear is also pivotally connected to the front edge 32 A of the door leaf 32 and via the rigid pivot lever 35 to the drive slide 36 .

The other end of the first push rod 44 is pivotally articulated in a pivot point 45 on a sliding element 42 which is guided in a longitudinally displaceable manner in an auxiliary guide 47 . This auxiliary guide is arranged obliquely to the main guide 37 and cuts it at an intersection S, which is approximately at the level of its center when the door leaf 32 is closed. At the level of the rear edge 32 B of the door leaf 32 , the auxiliary guide 47 merges into an arcuate path which, at a certain distance, surrounds a rotating column 34 to which the pivoting lever 33 is attached. The swing-out lever 33 is in a sliding engagement, analogously to the first exemplary embodiment, with its free end 33 A with a guide 48 on the door leaf 2 . This engagement is preferably carried out again by means of a slider 49 , on which both the swing-out lever 33 is pivotally attached with its end 33 A and the outer end of a second push rod 46 , which has its inner end in a joint 46 B on the slider 42 in a distance from the pivot point 45 is pivotally attached.

In the second embodiment 32 seals 54 and 55 are also shown on the front edge 32 A of the door leaf 32 and on the rear edge 32 B of the door leaf, which were omitted in the first embodiment for reasons of simplification. The seal 54 is designed so that it rests against the front edge of the door opening 23 . The seal 55 is designed in such a way that, with its approximately T-shaped design, its two legs seal against the outside of the side wall 22 and the door leaf 2 .

As in the first exemplary embodiment, the pivoting sliding door is preferably driven by a traction mechanism, for example in the form of a belt drive. Alternatively, however, other forms of drive are also 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.

If, starting from the closed position in FIG. 7, the drive carriage 36 is moved to the left along the main guide 37 by means of the traction mechanism, the front edge 32 A is pivoted outwards due to the curved section 37 B of the main guide 37 . At the same time, the first push rod 34 is driven along the auxiliary guide and thereby moves the second push rod 46, which is coupled to it via the sliding element 42 , so that the rear end of the door leaf 32 is also pivoted outwards in connection with the pivoting lever 33 . Overlaid for this purpose, a translatory movement of the door leaf to the rear takes place at the same time. An intermediate position in which the pivoting-out movement is completed is shown in FIG. 8. In the end position according to FIG. 9, roughly analogous to the first exemplary embodiment, the first push rod 44 , which is directly driven here via the pivot lever 35 , the sliding element 42 and the second push rod 46 form a triangle, which enables stable support of the front edge of the door leaf.
