Definitions
- the present invention relates to a spindle drive for an element to be driven, in particular a door or window wing of a vehicle, comprising a driven spindle with a longitudinal axis which extends through a spindle nut, so that the spindle nut can be moved along the longitudinal axis of the spindle by rotating the spindle.
- Such a spindle drive is used, for example, for opening and closing sliding doors or window sashes.
- the invention is described below for use with a door leaf, but should not be limited to this. In principle, the invention is suitable for all drive systems that have a spindle drive.
- the spindle nut is usually connected to the door leaf via the driver, so that the door leaf opens or closes a door opening when the spindle rotates. Regardless of the movement of the door leaf, further measures are often necessary or desired, for example locking or opening the door leaf separately. For this purpose, separate locking elements are usually used, which are actuated via building cables or linkages. Alternatively, locking can also take place via the motor brake of the spindle drive. All systems require additional installation space and are costly and maintenance-intensive.
- the object of the present invention is to provide a spindle drive via which, on the one hand, a driven element, for example a door or window leaf, can be moved, and on the other hand, for example, locking the door leaf is possible without any problems.
- a driven element for example a door or window leaf
- locking the door leaf is possible without any problems.
- the disadvantages of the prior art should be avoided, in particular the spindle drive should have a small installation space and have as few components as possible. Furthermore, the spindle drive should be low-cost and low-maintenance.
- the invention is based on the knowledge that the spindle nut, which is already driven, is not only used to drive the element to be moved, for example the door leaf, but also drives at least one other element, for example a locking device.
- the spindle nut is not only connected directly or indirectly to the door leaf, but also to another actuator. If the spindle is driven, the spindle nut initially moves along the longitudinal axis of the spindle, but does not initially drive the door leaf. While the spindle nut moves at the beginning of the travel path, only one actuator of the additional system, for example the locking system, is actuated.
- this first section of the travel path in which the driver does not yet move the door leaf, can be from a few millimeters to a few centimeters, preferably from about 0.5 cm to 2 cm.
- the spindle nut first drives the locking mechanism via the actuator and unlocks the door.
- the driver of the spindle nut then contacts a drive surface of a drive element for the door leaf via its contact surfaces and moves it.
- the two contact surfaces of the driver of the spindle nut point in opposite directions along the longitudinal axis of the spindle nut.
- the two drive surfaces are arranged at a distance from one another along the longitudinal axis of the spindle and face each other, so that the driver with the contact surfaces is located between them.
- the door can be locked in the opposite direction, for example, by using a latch or snap lock. So if the door leaf is moved into the door opening, a snap or latch lock automatically engages.
- a rotary latch which can be rotated or opened via the movement of the spindle nut, has proven to be particularly suitable.
- the two drive surfaces of the drive element of the door leaf are spaced apart from one another along the longitudinal axis of the spindle by a greater distance than the two contact surfaces of the driver of the spindle nut.
- the difference between the distance between the two drive surfaces and the distance between the two contact surfaces is decisive for the distance that the spindle nut can travel before the drive element is contacted and moved or for the movement that is available for actuating the lock via the actuator.
- the drive element and the two drive surfaces can be part of a spindle nut housing in which the spindle nut moves.
- the driver of the spindle nut extends into an elongated hole in the spindle nut housing that runs parallel to the longitudinal axis.
- the spindle nut housing is in turn firmly connected to the door leaf and drives it. Due to the elongated hole, it is possible for the driver to move along the elongated hole when the spindle nut is moved without moving the spindle nut housing. Only when the driver reaches the end of the elongated hole with its front contact surface in the direction of movement is the force transferred via the contact surface of the driver to the drive surface of the elongated hole and the spindle nut housing is moved. The length of the elongated hole determines the movement available to move the additional actuator.
- the actuator is firmly connected to the spindle nut and is also moved when the driver of the spindle nut is in contact with one of the drive surfaces.
- the actuator can operate another mechanism, for example an acoustic or visual signaling device. This depends primarily on the field of application of the spindle drive according to the invention.
- an auxiliary spindle nut can be provided, through which the spindle also extends.
- the auxiliary spindle nut serves to stabilize the entire system and cannot be moved between two drive surfaces, but is arranged stationary in the spindle nut housing.
- the auxiliary spindle nut In order to prevent the spindle nut housing from being moved by movement of the auxiliary spindle nut, the latter has a play in its thread with the external thread of the spindle that corresponds to the distance between the two drive surfaces of the drive element.
- the auxiliary spindle nut is therefore not initially moved; rather, the spindle only moves the auxiliary spindle nut when there is contact between one of the contact surfaces and the corresponding drive surfaces of the spindle nut.
- the spindle nut housing only moves when the play in the auxiliary spindle nut is balanced.
- the auxiliary spindle nut has no thread at all, but is merely designed as a plain bearing.
- the actuator is also designed in such a way that it only works after the spindle nut has first been moved by a certain distance.
- corresponding second drive surfaces are also provided for the actuator, which are also spaced apart from one another.
- the functional principle is the same, except that the distance between the first drive surfaces of the drive element of the door leaf can, for example, be greater than the distance between the second drive surfaces for the actuator. In this case, too, the actuator acts before contacting the contact surfaces of the driver of the spindle nut with the associated first drive surfaces.
- Figure 1 illustrates the basic functional principle of a spindle drive 20 according to the invention.
- a spindle 22 extends through a spindle nut 24 and has a longitudinal axis XX.
- the spindle nut 24 can be moved along the spindle 22 along the longitudinal axis XX.
- the spindle nut 24 has a driver 26 which has a first contact surface 28 and a second contact surface 30.
- the two contact surfaces point in opposite directions along the longitudinal axis X-X.
- the driver 26 or the contact surfaces 28, 30 can be brought into contact with a first drive surface 32 or a second drive surface 34 by moving the spindle nut 24.
- the two drive surfaces 32, 34 are firmly connected to a drive element 36, which in turn is firmly connected via a holder 38 to an element (not shown) to be moved, for example a door leaf.
- a distance A between the two drive surfaces 32, 34 exceeds a distance B between the two contact surfaces 28, 30 from each other, so that the driver 26 can be moved between the two drive surfaces 32, 34 without the contact surfaces 28, 30 and the drive surfaces 32, 34 touch or take or move the drive element 36.
- an actuator 40 is shown, which is also firmly connected to the spindle nut 24.
- a further element preferably a locking device, can be actuated via the actuator.
- a rocker arm 42 can be seen as an example for this purpose, which is switched by the actuator 40. It is essential that the rocker arm 42 is switched before the respective contact surface 28, 30 comes into contact with the corresponding drive surface 32, 34.
- the rocker arm 42 can be spring-loaded in order to be driven back into the original position after actuation. Accordingly, according to the invention, it is possible to trigger or switch two completely different functions via the spindle nut 24.
- Figure 2 shows a particularly advantageous embodiment variant of the invention, which is particularly suitable for driving a door or window leaf.
- a spindle nut housing 44 which has an elongated hole 46, is provided here as the drive element 36.
- the elongated hole 46 extends essentially along the longitudinal axis XX.
- the holder 38 is attached to the spindle nut housing 44, via which a door leaf (not shown) can be driven.
- the elongated hole 46 forms the two drive surfaces 32, 34 at the end.
- the driver 26 is round in the exemplary embodiment shown. and in The actuator 40 is also attached to the spindle nut 24 and is preferably used to unlock a rotary latch.
- a spring element 48 is shown, which counteracts unwanted play of the spindle drive 20.
- an auxiliary spindle nut 50 is arranged within the spindle nut housing 44 and is also driven by the spindle 22.
- the auxiliary spindle nut 50 has increased play inside. Only when this play has been overcome does the auxiliary spindle nut 50 drive the spindle nut housing 44.
- the play and the length of the elongated hole 46 are coordinated with one another in such a way that contact between the contact surfaces 28, 30 and the drive surfaces 32, 34 only occurs when the play within the auxiliary spindle nut 50 has also been overcome.
- the invention is not limited to the embodiment shown, but is suitable for all drive systems that have a spindle drive 20. Instead of locking devices, other elements can also be driven via the actuator 40.
