Description

[0001] The present invention relates to a device for performing an opening movement of a door, for example of a vehicle.

[0002] To facilitate entry and exit from passenger vehicles, these vehicles are equipped with doors that must meet specific requirements. The opening and closing movements of the doors can be controlled via guide rails attached to the vehicle.

[0003] The DD 117 851 describes a guide and locking device for unlocking and swinging out a door in front of the outer surface of a vehicle side wall and for subsequently moving the door out of the door opening.

[0004] EP 0 492 743 A1 describes a door system for use in a public transport vehicle. The door system comprises a door leaf, suspension elements with a telescopic guide, and a drive system.

[0005] EP 0 643 190 A2 describes a device for moving a swing-sliding door for passenger vehicles. A door leaf is connected via a pivot arm to a support member that is slidable on a guide element. The door leaf is supported by two roller levers that engage in guide rails on the door leaf.

[0006] EP 0 716 004 A1 describes a swing-sliding door for passenger vehicles. A door leaf arranged within a door frame is connected via a swing arm to a support member that is horizontally displaceable in the longitudinal direction of the vehicle on a guide element fixed in the door frame. The swing arm is articulated to both the door leaf and the support member via vertical pivot axes (3.2, 3.1), and its pivoting movement is determined by a guide lever guided in a guide rail.

[0007] The object of the present invention is to create an improved device for performing an opening movement of a vehicle door.

[0008] This problem is solved by a device according to claim 1.

[0009] This invention is based on the finding that the door's stroke can be extended if the movement of a door leaf support along a guide rail is transmitted asynchronously to the door. In this way, the door can move faster than the door leaf support along a stroke direction and thus overtake it.

[0010] The device according to the invention for performing an opening movement of a door thus represents a door stroke extension device that enables a stroke extension. With the device according to the invention, a greater door stroke can be achieved, e.g., in vehicles for transporting people, than would be possible solely through the stroke of the door leaf support within an available entry portal width.

[0011] By means of the stroke extension of a door according to the invention, a large door opening can be achieved even if the drive unit must be installed within the width of the portal. Extremely tight dimensioning of the components is not required, thus avoiding tolerance problems and ensuring suitability for higher loads. Furthermore, no articulated bearing and the associated pivoting movement of the entire or a substantial part of the door's support system are necessary, resulting in a more cost-effective and lightweight design.

[0012] The present invention provides a device for performing an opening movement of a vehicle door, wherein the opening movement has a component in an opening direction parallel to a main extension plane of the door, with the following features: a door leaf support which is movably arranged in the opening direction; a steering lever which is pivotably arranged on the door leaf support about a pivot point and has a first end and a free end;and a guide rail with a first end region and a second end region, wherein the first end region and the second end region of the guide rail have an offset relative to each other transversely and longitudinally to the opening direction, wherein the first end of the steering lever engages in the guide rail, and wherein the guide rail is configured to guide a movement of the steering lever in the opening direction and a pivoting movement of the steering lever, wherein the movement of the steering lever in the opening direction is transferable to the door to move the door in the opening direction, and a component of the pivoting movement at the free end of the steering lever in the opening direction is transferable to the door to move the door even further in the opening direction.

[0013] The vehicle can be a vehicle for passenger transport, such as a train or a bus. The door can be designed to allow boarding or alighting from the vehicle or loading of the vehicle. Alternatively, it can be a door of a building, structure, or other facility. The main extension plane can be the plane in which a door leaf is arranged. If the door is laterally displaced when opened, the opening direction or stroke can define the direction of movement of the door laterally along the vehicle. The straight initial section of the guide rail can be aligned parallel to the opening direction. The device according to the invention can act as a link between the vehicle and the door. The door leaf support can perform relative movement with respect to the vehicle. The movement of the door support can be transmitted to the door via the steering lever for opening the door.The door can be connected to the steering lever via a suitable fastening device. A suitable drive mechanism can be provided for moving the door carrier. The opening movement of the door in the opening direction can have two opening phases. A first opening phase is characterized by a linear movement of the steering lever in the opening direction, which is guided by the straight initial section of the guide rail and can be transmitted directly to the door. A second opening phase is characterized by an arcuate movement of the steering lever, which is guided by the arcuate section of the guide rail and can be transmitted indirectly to the door due to the leverage effect of the steering lever.The steering lever is designed to convert the arcuate motion of the first end of the steering lever, guided in the guide rail by the arcuate section of the guide rail, into a motion of the free end of the steering lever, such that one component of the free end's motion in the opening direction is greater than one component of the first end's motion in the opening direction. This allows the free end to catch up with and overtake the first end with respect to the opening direction.

[0014] Thus, the movement of the steering lever can be transmitted synchronously to the door, while the movement of the steering lever is guided by a straight initial section of the guide rail from the first end of the guide rail to the second end of the guide rail. Alternatively, the movement of the steering lever can be transmitted asynchronously to the door, while the movement of the steering lever is guided by an arcuate section of the guide rail, with the arcuate section being located at the second end of the guide rail. This allows the door to move faster than the door leaf support in the opening direction, while the movement of the steering lever is guided by the arcuate section of the guide rail. Thus, the door can overtake the door leaf support, thereby increasing the door stroke.

[0015] The movement of the steering lever can also be transferred to the door, while the movement of the steering lever in the guide rail is guided linearly from the first end of the guide rail to the second end of the guide rail, so that the door moves faster than the door leaf support in the opening direction. This allows the device to be provided more simply and cost-effectively, while maintaining full functionality. The opening speed of the door can thus be kept almost constant over the entire stroke range.

[0016] The device according to the invention comprises a door guide attached to the door leaf support. The door guide is designed to allow the door to move relative to the door leaf support in the opening direction during the pivoting movement of the steering lever. The door guide can be designed as a rail aligned parallel to the opening direction. In the first opening phase, during which the movement of the steering lever is guided by the straight initial section of the guide rail, the door can move synchronously with the door guide. In the second opening phase, during which the movement of the steering lever is guided by the curved section of the guide rail, the door can move relative to the door guide in the opening direction.

[0017] The device according to the invention can have a tab that is pivotably attached to the free end of the steering lever. The tab allows the movement of the steering lever in the opening direction and the component of the pivoting movement at the free end of the steering lever in the opening direction to be transmitted to the door. For this purpose, the tab can be pivotably attached to the door.

[0018] The opening movement of the door has a further component in a transverse direction perpendicular to the main plane of extension of the door. The device according to the invention has a carriage on which the guide rail is mounted. The carriage is movably arranged in the transverse direction. Thus, the guide rail can move transversely relative to the vehicle together with the carriage. When the door is opened, the transverse direction can be directed away from the vehicle, i.e., outwards.

[0019] The door leaf support can be movably mounted on the carriage via a guide device in the opening direction and can move laterally with the carriage. The guide device can direct the movement of the door leaf support. This guide device can be designed as a guide rod. A suitable coupling device can transmit the laterally moving movement of the door leaf support to the carriage.

[0020] The device according to the invention comprises a vehicle-mounted guide rail with an arcuate initial section and a straight section adjacent to it in the opening direction. The door leaf support engages in the guide rail. The guide rail is designed to guide movement of the door leaf support in the transverse direction by means of the arcuate initial section and movement of the door leaf support in the opening direction by means of the straight section. The guide rail can be rigidly connected to the vehicle. The straight section can be aligned parallel to the opening direction. By means of the guide rail, the door leaf support, and via the door leaf support also the carriage with the guide rail, can be moved in the transverse direction.

[0021] The guide rail can be arranged parallel to the door and offset from the guide rail in the transverse direction. The curved section of the guide rail can point towards the guide rail. The curved initial section of the guide rail can point away from the guide rail.

[0022] According to one embodiment, the door leaf support can engage in the guide rail by means of a first guide roller, which is designed to guide the door leaf support, the carriage, the guide device, the guide rail, the steering lever, the tab, the door guide, the door and a drive in the transverse direction by means of the arcuate initial section, and to guide the door leaf support, the steering lever, the tab, the door guide and the door along the guide device in the opening direction by means of the straight section, wherein the steering lever engages in the guide rail by means of a further guide roller, which is designed to hold the steering lever in a position opposite to the opening direction by means of the offset of the first end region of the guide rail and to pivot the steering lever in the opening direction by means of the offset of the second end region of the guide rail.

[0023] The device according to the invention can be designed to be arranged within a recess provided for the door in a vehicle body. In this way, the device can be protected from environmental influences and can utilize the existing installation space in the door frame.

[0024] Preferred embodiments of the present invention are explained in more detail below with reference to the accompanying drawings. These show: Fig. 1. A representation of a device according to the invention on a closed door; Fig. 2 a representation of a device according to the invention on a partially opened door; Fig. 3 a representation of a device according to the invention on an open door; Fig. 4 a representation of a device according to the invention on a fully opened door; Fig. 5 one of the Fig. 3 corresponding illustrations showing the door in its entirety; Fig. 6 one of the Fig. 4 corresponding illustrations showing the door in its entirety; Fig. 7 an illustration of an embodiment of a device according to the invention on a closed door; and Fig. 8 one of the Fig. 7. Corresponding illustration on a fully opened door.

[0025] In the following description of the preferred embodiments of the present invention, the same or similar reference numerals are used for the elements shown in the various drawings and acting similarly, and a repeated description of these elements is omitted.

[0026] The Fig. 1, Fig. 2, Fig. 3 to Fig. Figure 4 shows a device for performing an opening movement of a door, according to an embodiment of the present invention, in different positions during the opening movement sequence. Fig. 1 and Fig. Figure 4 each shows extreme points of the movement sequence and the Fig. 2 and Fig. 3 show points in the movement sequence where crucial changes in the movement sequence occur.

[0027] The device for performing the opening movement of the door comprises a spindle 1, a nut 2, a door leaf support 3, a door guide 3.1, a roller 4, a guide rail 5, a carriage 6, a guide rod 7, a guide rail 8, a steering lever 9, and a tab 10, which is coupled to the door 11 to be opened. A roller 12 of the device and a portal edge 13, for example of a vehicle, are also shown.

[0028] Fig. Figure 1 shows door 11 in a fully closed position. Starting from this fully closed position, door 11 is moved laterally, perpendicular to the door plane, with a small component in the opening direction, parallel to the door plane, to achieve the Fig. to achieve the state shown in 2. Starting from the state shown in Fig. In the state shown in 2, door 11 moves exclusively in the opening direction. Between the in Fig. 2 shown condition and the one in Fig. In the state shown in section 3, door 11 is moved at a speed determined by a drive mechanism. The drive mechanism consists of spindle 1 and nut 2. Once the in Fig. At point 3 shown, the velocity component in the opening direction of the steering lever 9 is added to the speed of the drive until the end position is reached as shown in Fig. 4 is shown.

[0029] The opening movement of door 11 is described below using the Fig. 1, Fig. 2, Fig. 3 to Fig. 4 described in more detail. In the embodiments described below, the device according to the invention is referred to as a door drive with stroke extension device.

[0030] Fig. Figure 1 shows an embodiment of the door drive according to the invention with a lifting extension device for a single-leaf swing-sliding door with door 11. The door 11 is in the closed position. If, for example, the spindle 1 with the nut 2 is used as the drive means and the spindle 1 is driven in the opening direction, the door leaf carrier 3 is moved in the opening direction. The roller 4, attached to the door leaf carrier 3, is guided in the portal-fixed guide rail 5, whereby the entire carriage 6, and with it the spindle 1, nut 2, guide rod 7, door leaf carrier 3, guide rail 8, steering lever 9, tab 10, and ultimately the door 11, are moved relative to the portal, transversely to the door's longitudinal opening direction, from the inside of the carriage towards the outside, until the Fig. The position shown in point 2 has been reached.

[0031] Fig. Figure 2 shows the door 11 with the drive in a fully laterally swung-out position. When the spindle 1 is driven further, the roller 12, guided in the guide rail 8 and pivotally connected to the door leaf support 3 via the steering lever 9, and the door 11 continue to move in the opening direction until the position after Fig. 3 is reached. In the Fig. At position 3 shown, a door lift-1 301 is reached.

[0032] Fig. Figure 3 shows the door 11 open along the door stroke 1 301 until the roller 12 on the steering lever 9 enters the curved section of the guide rail 8. The door 11 is mounted longitudinally displaceably on the part 3.1 of the door leaf support 3, which serves as a door guide. As the opening movement continues, the roller 12, guided in the guide rail 8, is deflected in the arcuate section of the guide rail 8, causing the steering lever 9 to pivot about a pivot point located on the door leaf support 3. The tab 10 is pivotally connected to the steering lever 9 on one side and to the door 11 on the other, so that the pivoting movement of the steering lever 9 exerts an additional sliding effect on the door 11, which is superimposed on the opening direction of the door leaf support 3. The door 11 begins to overtake the door leaf support 3 until the door 11 finally reaches its open end position. In the Fig. Position 4 shows a door lift-2 402.

[0033] Fig. Figure 4 shows the door 11 fully open, after the door stroke 2 402 has been completed, with the steering lever 9 pivoted in the open end position. In this way, the door 11 can achieve a greater opening stroke than would be possible solely through the movement of the door leaf carrier 3, guided on the guide rod 7, within the available portal width. The consistently required clear opening width between the portal edge 13 and the open door 11, as large as possible relative to the available portal width, is thus met.

[0034] In Fig. Figure 4 shows a total door stroke 403, which is composed of door stroke 1 301 and door stroke 2 402. A guide stroke 1 405 and a guide stroke 2 407 are also shown.

[0035] In the following, the device according to the invention will be described with reference to the Fig. 1, Fig. 2, Fig. 3 to Fig. The four illustrated examples are described in more detail.

[0036] Fig. Figure 1 shows the door 11 of a vehicle in the closed position with the device according to the invention for opening the door 11. The vehicle-mounted guide rail 5 is visible, with an inclined, a curved, and an adjacent straight section. The roller 4 of the door leaf support 3, designed as a guide roller, engages in the guide rail 5. The door leaf support 3 is connected to the guide roller 4, the guide rod 7, the drive threaded nut 2, the steering lever 9, and the door guide 3.1. The guide rod 7 is connected to the door leaf support 3 via a sliding sleeve and is connected at its ends to the laterally displaceable carriage 6, which, parallel to the door 11, carries the guide rod 7, the spindle 1 (designed as a threaded spindle) which drives the nut 2 (designed as a threaded nut), and the guide rail 8 with a straight and an adjoining curved section.Carriage 6 is in the closed position, moved away from the outside of the vehicle, i.e., shifted into the vehicle interior. The steering lever 9 is movably connected to the door leaf support 3 via a pivot point in a bend of the steering lever 9 and engages the guide rail 8 at one end via the further roller 12, which acts as a guide roller. The tab 10 is rotatably attached to the other end of the steering lever 9. A door leaf is longitudinally displaceable on the door guide 3.1, which, in the state shown, completely covers one portal width of the vehicle and is flush with the outside of the vehicle. In the closed position, the door leaf can rest at its edges against portal-fixed angles with seals (not shown). The tab 10 ensures the connection between the steering lever 9 and the door leaf.

[0037] The guide rail 5 can extend over almost the entire width of the door opening. At its end opposite the opening direction, the guide rail 5 is bent away from the vehicle's outer skin at a slight radius of almost 90°. This is followed by a short straight leg, the length of which, together with the transverse component of the bend, essentially corresponds to the door's stroke length in the transverse direction.

[0038] The guide rail 8 can extend over almost the entire width of the door opening. At its end, which lies in the opening direction, the guide rail 8 is bent away from the vehicle's outer skin at a radius approximately 45°, which is larger than the radius of the guide rail 5. The transverse component of the bend corresponds essentially to the leg length of the shorter leg of the steering lever 9.

[0039] The door guide 3.1 can extend in the opening direction approximately over half the length of the door in the opening direction.

[0040] The steering lever 9 has a longer and a shorter leg. These can be arranged at an angle of approximately 135° to each other around the pivot point on the door leaf support 3. The roller 12, designed as a guide roller, is arranged on the shorter leg. The rotatable connection with the tab 10 is arranged on the longer leg.

[0041] Fig. Figure 2 shows the door 11 in its fully laterally swung-out position. The nut 2, designed as a threaded nut, has been moved a small amount in the opening direction by the spindle 1, designed as a threaded spindle. In doing so, it has moved the door leaf support 3. This support, in turn, has been moved along the inclined and curved section towards the outside of the vehicle via the roller 4, designed as a guide roller running in the guide rail 5. Together with the door leaf support 3, the door leaf and all parts of the device, except for the vehicle-mounted guide rail 5, have been moved towards the outside of the vehicle.

[0042] Fig. Figure 3 shows a vehicle door 11 in a fully laterally swung-out position and open along the door stroke 1 301 up to the point where the roller 12 on the steering lever 9 enters the curved part of the guide rail 8 with a device according to the invention for opening the door 11. The nut 2, designed as a threaded nut, was moved in the opening direction by the spindle 1, designed as a threaded spindle. In doing so, it moved the door leaf carrier 3. The door leaf carrier 3 was guided over the straight section in the opening direction by the roller 4, which runs in the guide rail 5 and is designed as a guide roller. The vehicle 6 with its attached parts remained in its fully laterally swung-out position. The door leaf, the door guide 3.1, the guide sleeve, the steering lever 9, and the latch 10 were moved along with the door leaf carrier 3.The steering lever 9 is prevented from moving relative to the door leaf support 3 by the roller 12, which is guided in the straight section of the guide rail 8 and designed as a guide roller.

[0043] Fig. Figure 4 shows the door 11 in its fully laterally swung-out position and fully open after the door stroke 2 404 has been completed, with the steering lever 9 pivoted in the open end position. The nut 2, designed as a threaded nut, has been moved further in the opening direction by the spindle 1, designed as a threaded spindle. In doing so, it has moved the door leaf support 3. This support has been guided over the straight section in the opening direction by the roller 4, which runs in the guide rail 5 and is designed as a guide roller. The carriage 6 with its attached parts has remained in its fully laterally swung-out position. The door leaf, the door guide 3.1, the guide sleeve, the steering lever 9, and the latch 10 have been moved along with the door leaf support 3.The steering lever 9 is set into a pivoting movement relative to the door leaf support 3 by the roller 12, which is guided in the curved section of the guide rail 8 and acts as a guide roller, and has transmitted a component of its pivoting movement in the opening direction to the door leaf via the tab 10. The door leaf is now in its fully open position.

[0044] The movements described in relation to the opening movement of door 11 can be performed in reverse order to perform a closing movement of the door.

[0045] The Fig. 5 and Fig. 6 correspond to the Fig. 3 and Fig. 4 where door 11 is in the Fig. 5 and Fig. 6 is shown in full.

[0046] Fig. Figure 7 shows a further embodiment of a device according to the invention on a door 11 shown in the closed position. With the exception of one variant of the guide rail, which is shown here in the form of a guide rail 702, all elements of the device are depicted as in the figures described above. The variant of the guide rail 702 extends in a straight line from a first end region to a second end region. It is inclined at an angle to the opening direction of the door 11. This causes the roller 12, designed as a guide roller, to be continuously deflected further on the steering lever 9 during the entire opening process. The roller 12 pivots the steering lever 9, designed as a lever, about its pivot point, and the door 11 is opened further by the component of the pivoting movement in the opening direction of the free end of the guide lever 9.

[0047] Fig. Figure 8 shows an exemplary embodiment of the device. Fig. 7, with the door 11 in a fully open position. The roller 12, designed as a guide roller, has been deflected largely transversely to the opening direction by the straight version of the guide rail 702 and has thereby pivoted the steering lever 9. The door 11 has received the component in the opening direction of the pivoting movement of the free end of the steering lever 9 and has opened further in the opening direction than the door leaf support 3 has moved.

[0048] Unlike those in the Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5 to Fig. In the 6 illustrated embodiments, the guide rail is in the Fig. 7 and Fig.The embodiment shown in Figure 8 is designed without curvature on the opening side, but is inclined at an angle to the main opening direction of the door. This results in a relatively constant opening speed of the door over the entire stroke range. The device is therefore also applicable to simple sliding doors or pocket sliding doors.

[0049] The device according to the invention can also be used for multi-leaf entrances. In this case, a second identical device can be arranged next to the device shown. The second device can be rotated 180° relative to the device shown, so that the opening movements of the doors moved by the two devices are opposite.
