Description

The invention relates to a guide system for a sliding door, in particular motor vehicle sliding door, with the features in the preamble of claim 1. Furthermore, the invention relates to a sliding door with such a guide system with the features of claim 9 and a motor vehicle equipped therewith according to the features of claim 10.

Sliding doors are mainly used in vehicle construction for box bodies for commercial vehicles, in order to obtain comfortable access to the load compartment without having to pass through a large swing radius in question. In this case, the sliding doors must be guided parallel to a side wall of such a box body.

The parallel arrangement requires only a displacement of the door leaf to open, while the arrangement in the plane of the frame of the box body initially requires a displacement of the door panel perpendicular to this and thus out of the opening. The benefits of placing the door panel in the plane (closing plane) of the frame range from simplified sealability to improved aerodynamics with reduced wind noise, to an overall higher quality appearance.

Sliding doors with a door leaf arranged in the plane of the frame require special guidance systems in order to be able to realize the movements of the door leaf required for opening and closing. Guide systems used in motor vehicles generally have guide rails or rails arranged in the side wall or at least on the outside thereof, in which bearing means carrying the door leaf can be moved. The disadvantage here is that the guide rails or rails need an adapted to the zurücklegbare by moving the length of the door leaf length. As a result, equipped with such a guide system sliding doors must maintain a sufficient distance from the ends of the side wall, so that an arrangement of the opening, for example, at a front end of the side wall is not feasible.

From the DE 200 06 997 U1 a sliding door for a motor vehicle is known, which has a modified guide system with a telescoping linear extension in the direction of its longitudinal axis. For this purpose, the linear puller has relatively mutually displaceable rails, of which a first rail is connected to the door leaf, while a second rail is fastened by two bearing means to the door frame corresponding to the door leaf of the sliding door. The arranged on each one of the two end portions of the second rail bearing means are pivotally formed so that the door leaf from its located within the door frame closing level out in a to Telescoping the linear extension provided shift plane is displaced into it. In this position, the door leaf can be moved parallel to the opening.

The known guide system allows the waiver of arranged in or on the side wall of the motor vehicle guide rails or rails. In this way, the door leaf of the sliding door can also be located near the end of the side wall of the motor vehicle. The closing of the sliding door is done by moving the door leaf in the closing plane by means of a short pivoting movement, which may sometimes require sufficient momentum in large openings and correspondingly large door leaf. If there is insufficient momentum, the closing operation requires a force distributed as equally as possible in order to pivot the door leaf, which is movable parallel to the door frame, out of the displacement plane into the closing plane. This is accompanied by a corresponding noise and vibrations. If the door leaf does not have sufficient mass, the closing process is generally more difficult. In particular, in the case of vehicles intended for the transport of persons, their danger can not be ruled out due to the energetic operation of the sliding door. Thus, the abrupt swiveling in of the entire door leaf over its entire width in the event of carelessness can definitely lead to collisions or even contusions of limbs.

Against this background, the present invention seeks to further develop a generic guide system as mentioned above and a sliding door equipped therewith so that an overall simpler and controlled over the entire opening and closing operation of the door panel is made possible even with large openings and lightweight door leaf ,

This object is achieved by a guide system for a sliding door with the features of claim 1, a sliding door with the features of claim 9 and a vehicle having the features of claim 10. Advantageous developments are content of the dependent claims.

The guide system according to the invention comprises a telescoping linear extension, which has at least two parallel to its longitudinal axis relatively mutually displaceable rails. From the rails of the linear puller, an outer rail is provided for connection to a door leaf of the sliding door. An inner of these rails has two bearing means, each coupled to one of its two end sections, which are provided for fastening the linear pull-out in the region of a door frame corresponding to the door leaf.

According to the invention, one of the two bearing means is a hinge, while the other bearing means is designed as a display device. This has the inner rail and thus the entire linear extension by the hinge a virtually fixed end pivot point, while only the opposite end of the inner rail and thus the entire linear pull-out by means of the Ausstellvorrichtung is limitedly pivotable. In this case, the hinge and the Ausstellvorrichtung are arranged and configured so that the linear extension by displacement of the coupled with the Ausstellvorrichtung second end portion of its inner rail - around a rotational axis of the hinge - from a closing plane in a provided for its telescoping shift plane and back is pivoted.

The coupleable with the guide system door leaf therefore needs to be relocated only on one side. In other words, equipped with the guide system according to the invention sliding door initially behaves analogous to a conventional door by the door initially pivots after unlocking only on one side of the closing plane, while the opposite side is initially only rotatably supported due to the hinge. As a result, the plane of the door frame or the closing plane and the plane of the door leaf coupled to the guide system form an angle therebetween, so that the subsequent displacement of the door leaf takes place at the same angle.

In particular, the closing process is very simple and controlled. This is how the door leaf first looks like pushed back far to the opening until the hinge-facing edge region of the door leaf has arrived in the plane of the door frame. The locking takes place by pivoting the door leaf around the axis of rotation of the hinge, so that this sequence of movements corresponds to the closing of a conventional door. In particular, the actual locking does not require a sweeping and thus uncontrolled movement of the door leaf, so that this can always be controlled and gently pivoted into the closing plane.

The possible arrangement of an actuating device on the outside of the door leaf in the region of the pivotable side of a relatively intuitive operation of a sliding door thus equipped can be achieved.

According to a particularly preferred embodiment of the invention, the opening device may comprise a holder connected to the second end portion of the inner rail. Furthermore, the opening device may have a provided for attachment in the region of the door frame bearing element on which a support lever is rotatably mounted. Advantageously, the rotation of the support lever can take place about an axis of rotation extending parallel to the axis of rotation of the hinge. A first free end of the support lever may have a receptacle which serves to connect to a rod axis mounted therein.

About the rod axis then arranged on the inner rail holder is pivotally connected to the support lever of the door frame mounted on the bearing element.

Due to the rotatable mounting of the support lever on the bearing element on the fixed door frame coupled to the support rod rod axis describes a circular motion, with the help of the linear extension - and thus a door leaf to be arranged - limited from the closing plane can be issued out.

The thus designed Ausstellvorrichtung may advantageously be designed so that the arranged on the inner rail of the linear extension holder is designed substantially U-shaped. For this purpose, the holder may have two legs, which are connected to one another via a web. Preferably, the holder can then be connected via its web to the inner rail, while its two legs extend away from the linear extension. In this case, the two legs of the holder may each comprise an elongated passage opening (slot), through which then the rod axis of the support lever is arranged.

Due to the configuration of the arranged in the legs of the holder through holes as slots, the rotation of the rod axis is not limited to a circular path around the articulated mounting of the support lever around. In fact, this can be done in a corresponding tuning of length reach the support lever and the length of the through holes ideal rotation about the located at the opposite first end portion of the inner rail and thus the linear extension axis of rotation of the hinge.

It can preferably be provided that the support lever can be rotatably mounted on a cantilever arm of the bearing element connectable to the door frame. Due to the arrangement on the cantilever arm results in an advantageous spacing of the support lever relative to a door leaf, so that the support lever has a sufficiently large rotation angle. Particularly preferably, the cantilever can be formed and / or bounded by this part of the bearing element which projects back relative to the bearing element. The support lever may in particular comprise two parallel spaced lever elements, which are spaced apart by incorporation of two spacers. In each case one of the two spacers is advantageously arranged in the region of the first free end and in the region of a first free end opposite the second free end of the support lever. Spacers and cutouts of the bearing element can be located to each other so that upon rotation of the support lever in each case one of the two spacers is displaceable up to a contact with the bearing element in the associated section.

With this configuration, the two spacers lead to a natural limitation of the rotation of the support lever in the form of end stops.

According to a preferred embodiment of the opening device of the guide system, the bearing element which can be fixed to a door frame can have a projection on which a prestressed or prestressable spring element is articulated. Advantageously, the spring element may be a low-maintenance gas spring. In this embodiment, the spring element can then be articulated to the support lever, that a rotation of the support lever from its respective end position is initially only possible against the spring force of the spring element. Since the rotation of the support lever is accompanied by a pivoting movement of the linear pull-out and a door leaf which can be arranged thereon, the pivoting of the linear pull-out from the closing plane into the displacement plane and back is always initially feasible only against the force of the spring element.

In this case, the spring element may be connected in a particularly preferred manner with the support lever, that its spring force holds the linear extension in the closing plane and in the displacement plane. The respective pivoting direction of the linear pull-out from one of these two levels up to a middle position between the closing plane and the displacement plane is then initially against the spring force of the spring element. When the middle position (over-center) is exceeded, the further pivoting movement is then assisted by the spring element, so that the force required for this purpose is reduced to a minimum.

The bearing element may be, for example, a welded construction or a molded part or a bending mold.

The guide system according to the invention may preferably comprise a guide strip opposite the linear extension, preferably against a vertical direction. The guide bar can be advantageously connected to a lower portion of the door frame. The guide strip may preferably have a parallel to the displacement plane extending channel. Furthermore, at least one roller can be provided which is rotatably mounted on a guide arm provided for coupling to the door leaf of the sliding door. The role is designed and arranged so that it at least partially engages in the channel and is movable along the channel.

Due to the role in combination with the roller rotatably supporting guide arm results in a three points realized storage of a coupling with the guide system door leaf. Advantageously, the guide arm can be arranged below the hinge, so that the guide bar is only to be arranged in the region of the opening to be closed by a door leaf.

The roller may preferably have a circumferentially circumferential annular groove. In this case, the guide strip may have a channel which limits its channel on one side. The roll is advantageously arranged on the upstand, so that the upstand is at least partially encompassed by the annular groove of the roller. In this way, the roller with corresponding side guide through the annular groove on the free edge of the upstand roll.

The linear extension may comprise at least one further rail in the form of an inner rail. The inner rail may be at least partially disposed between the outer rail and the inner rail of the linear extension. In order to enable the relative mobility of the rails with each other, they can be supported against each other in a particularly preferred manner via a plurality of rolling elements.

As the number of rails increases, the length of telescopic operation of the linear pull-out can be increased accordingly.

The invention provides a highly practical guide system for guiding and supporting a door leaf of a sliding door. In particular, the reference to the one-sided pivotability of conventional doors allows an overall simple and over the entire opening and closing operation controlled operation of the door leaf, which is operated for a person with one hand. Particularly noteworthy is that the guide system according to the invention suffers no restrictions with increasing opening size and a correspondingly large door leaf and / or light door leaves.

The invention is further directed to a sliding door, which may be a motor vehicle sliding door in a particularly preferred manner. The sliding door has a door leaf connected to a guide system according to the invention as indicated above.

Furthermore, the invention is directed to a motor vehicle equipped with a sliding door according to the invention as described above and a guide system as indicated above according to the invention or a box body for a motor vehicle.

The resulting from the sliding door according to the invention and the motor vehicle according to the invention advantages have already been explained above, so reference is made to avoid repetition of the above statements.

Fig. 1 shows a case of the invention 1 of a motor vehicle not shown in detail with a sliding door 2 according to the invention in an exterior view. Shown here is the sake of simplicity, only one side wall of the box body 1. The box body 1 extends in a horizontal longitudinal direction x and a not further apparent here transverse direction y perpendicular to the page plane and a vertical direction z. The sliding door 2 arranged in a side wall 1a of the box body 1 which can be seen here has a door leaf 3 with a width extending in the longitudinal direction x and a height extending in the vertical direction z. The door leaf 3 has an actuating device 4 arranged on the outside thereof in order to lock and / or unlock the locking system of the sliding door 2, which is not shown here in greater detail. In the external view shown here, the sliding door 2 is closed, wherein the door leaf 3 is in a closing plane A in the plane of the side wall 1a.

Fig. 2 shows the reduced to a door frame 5 of the box body 1 side wall 1 a Fig. 1 in combination with the sliding door 2 in a perspective interior view. It can be seen that the door leaf 3 of the sliding door 2 is moved out of its closing plane A, so that an opening 6 bounded by the door frame 5 is no longer covered by the door leaf 3. The sliding door 2 has a guide system 7 which serves to support and guide its door panel 3. The guide system 7 comprises a linear pull 8 arranged in the vertical direction z above the opening 6 and a guide arm 9 opposite to the vertical direction z in the lower area of the opening 6, on which a roller 10 is rotatably mounted. Looking back at Fig. 1 It is clear that the guide arm 9 with its roller 10 with a linear pull 8 opposite, arranged below the opening 6 guide bar 11 corresponds.

Fig. 3 shows a plan view of the located above the opening 6 part of the guide system 7 of the sliding door 2 facing the high direction z. Recognizable here is the door leaf 3 here again in closing plane A in the plane of here only indicated side wall 1a of the box body 1. From this supervision shows that the here by a fixed to the door frame 5 bearing element 12 of the guide system 7 concealed linear extension 8 via two bearing means is connected to the door frame 5. With respect to the representation of Fig. 3 The storage means located on the left is a hinge 13, while the storage means located on the right is designed as a display device 14. In the region of the hinge 13, the roller 10 arranged on the guide arm 9 is also recognizable.

Fig. 4 shows the supervision Fig. 3 in a reduced to a few parts presentation. It can be seen that the bearing element 12 has a cantilever arm 15, which is bounded by recesses 16, 17 of the bearing element 12, which project back relative to the latter. Furthermore, the bearing element 12 has a projection 18 which is also limited on its side facing the cantilever 15 by the cutout 16. On the side of the hinge 13, a boom 19 can be seen, which extends just like the cantilever 15 and the projection 18 to the interior of the box body 1 out.

With renewed reference to Fig. 3 is seen in light of the foregoing, that on the cantilever 15, a support lever 20 is rotatably mounted. Furthermore, an extending between the support lever 20 and the projection 18 spring element 21 is arranged in the form of a gas spring. In this case, the spring element 21 is supported on the projection 18 hingedly and is pivotally connected to the support lever 20 such that a rotation of the support lever 20 is made possible from its respective end positions only against the spring force of the spring element 21.

Fig. 5 illustrates the structure of the display device 14 in a perspective detail view. Visible, the support lever 20 has two parallel spaced lever elements 20a, 20b. In the region of a first free end 21 and a second free end 22 of the support lever 20, this further comprises a respective spacer body 23, 24. In this way, the two lever elements 20a, 20b of the support lever 20 by incorporation of the spacers 23, 24 spaced from each other. The two spacers 23, 24 are arranged opposite the bearing element 12 in such a way that in each case one of the spacers 23, 24 is displaceable alternately into its cutouts 16, 17 in its end position which can be changed by a rotation of the support lever 20 up to a contact with the bearing element 12 ,

Fig. 6 shows a detail section through the door leaf 3 in the region of the display device 14 by the linear pull 8 therethrough. In the present case, the linear extension 8 comprises three rails 8a, 8b, 8c, of which an inner rail 8a faces the interior of the box body 1, while an outer rail 8b is arranged facing away from the interior of the box body 1. The three rails 8a, 8b, 8c are each supported by rolling elements, not shown here, against each other, so that they are parallel to the longitudinal axis x1 of the linear extension 8 relative to each other slidably. This results in a telescoping of the linear extension 8 overall in the direction of its longitudinal axis x1.

As Fig. 6 Further, the display device 14 comprises a holder 25, which is connected to a second end portion 26a of the inner rail 8a. The holder 25 has two parallel aligned and extending away from the linear extension 8 legs 25a, 25b, which are connected to each other via a web 25c. In this case, the holder 25 is connected via its web 25c to the second end portion 26a of the inner rail 8a of the linear extension 8. In not shown here in more detail, the hinge 13 is connected to a first end portion 26b of the inner rail 8a. In contrast, the outer rail 8b is used to connect the door leaf 3 with the linear extension 8.

With reference back to Fig. 5 It is clear that the two legs 25a, 25b of the holder 25 each have an elongated Through hole 27 have in the form of slots. At the first free end 21 of the support lever 20, a receptacle is located in which a rod axis 28 is mounted. The rod axis 28 is further arranged through both passage openings 27 of the holder 25, so that the holder 25 is pivotally connected to the support lever 20. In the rod axis 28 is a loaded to train component to which the linear pull 8 and thus the door leaf 3 is attached via the holder 25 quasi.

Fig. 7 that already shows Fig. 3 Known, the linear pull 8 and the door leaf 3 are inclined relative to the longitudinal direction x, so that for example the longitudinal axis x1 of the linear pull 8 and the longitudinal direction x an angle c between them lock in. The hinge 13 and the display device 14 are arranged and configured in an already clarified manner, that the linear extractor 8 by displacing the hinged to the Ausstellvorrichtung 14 second end portion 26 a of its inner rail 8 a about a rotation axis z1 of the hinge 13 from the closing plane A in the for telescoping the linear extension 8 provided shift plane B and is pivotable back.

Fig. 8 is another supervision in cutting plane through the linear extract 8 to see through. In this supervision is particularly well the storage of the rod axis 28 within the elongated through holes 27 of the holder 25 can be seen.

Fig. 9 shows the final opening case of the sliding door 2 with completely uncovered opening 6. For this purpose, the previously pivoted in displacement plane B door leaf 3 was displaced parallel to the longitudinal axis x1 of the linear extension 8.

Fig. 10 is already out Fig. 1 emerge leading guide bar 11 again in a perspective detail detail. It can be seen that the guide rail 11 is fixed to the door frame 5 via three suspensions 29a, 29b, 29c below the opening 6 in the present case. The guide rail 11 has a parallel to the displacement plane B extending channel 30, wherein the roller 10 engages in a manner not shown here at least partially in the channel 30 and is movable along this. In fact, the guide rail 11 has a channel 30 delimiting upstand 31, which extends parallel to the vertical direction z. The parallel course to the displacement plane B refers primarily to the upstand 31, which can be seen achieved by a triangular shape of the guide rail. In contrast, the roller 10 has a circumferential circumferential groove 10 a (see Fig. 8 ), with which the roller 10, the upstand 31 at least partially engages, while the roller 10 rests on the upstand 31 and is unrolled on this.

At one with respect to the representation of Fig. 10 the right-hand end portion of the guide rail 11, the upstand 31 has seen a lowering 32 on. The countersink 32 is adapted to the roller 10 of the guide arm 9 so that the roller 10 engages at least partially in the depression 32 when the sliding door 2 is fully opened and thus telescoped linear extension 8. In this way, a locking of the door panel 3 is achieved in its displaced to release the opening 6 position. If a design-related compliance of the linear guide 8 in its telescoped state is not sufficient, the roller 10 may be mounted, for example, parallel to the vertical direction z movable on the guide arm. Of course, this mobility can be present even with a sufficient compliance of the linear guide 8. At least the mobility allows the roller 10, the distance between the upstand 31 and the lowering 32 to overcome. In particular, by a spring load of the relative to the guide arm 9 movable roller 10, the locking of the door panel 3 can be further improved.
