Description

The invention relates to a handle device for a door, in particular a motor vehicle door, with a handle element, which is displaceable between a rest position in the door at least substantially recessed and a use position protruding from the door, and with a device for displacing the grip element.

Furthermore, the invention relates to a door assembly for a vehicle, in particular motor vehicle, with a door having a door outer panel with a handle recess, and with a grip recess associated with the handle device.

Handle devices and door arrangements of the type mentioned are already known from the prior art. Doors of motor vehicles usually have an outer handle, by means of which the door can be pulled from a closed position to an open position. In order to improve the design or the flow resistance of the motor vehicle, it is also known to arrange the handle member displaceably on the door, so that it is substantially flush in a rest position with an outer lining of the door and thus sunk into the door, and in a Used position is moved out of the recessed position, so that it is tangible by a user.

The publication DE 10 2012 221 169 A1 For this purpose, for example, proposes a linearly movable grip element to which an actuator with a joint system for displacement is assigned.

From the publication DE 10 2013 215 896 A1 a handle device is already known, which also has a linearly displaceable gripping element, wherein an actuator with an eccentric arrangement is provided for the displacement.

Furthermore, from the published patent application DE 10 2012 221 184 A1 a handle device for a door is known, which has a pivotable handle element.

The publication DE 10 2012 112 706 A1 further describes a handle device with a handle member which is displaceable in a rest position and in a use position. In addition, a device for displacing the grip element is provided, wherein the device has at least one spring element and a cable pull. From the documents DE 198 05 509 A1 and US 2005/0121924 A1 Go out in each case handle devices with a handle member for a vehicle door, wherein the handle elements are displaced in a rest position and in a use position.

The known solutions provide in each case a device for displacing the gripping element, which is directly mechanically coupled to the gripping element in order to shift the gripping element forcibly guided into the rest position or into the use position. In addition, the known solutions provide each handle elements, which have an opening for engaging the user.

The invention has for its object to provide a handle device and a door assembly, which increase the security against damage and / or improve the usability of the handle member.

The object underlying the invention is achieved by a handle device with the features of claim 1. This is characterized by the fact that the device has at least one spring element urging the grip element into the use position and a cable which is connected at one end to the grip element and at the other end to an actuatable actuator so that the grip element can be actuated against the force of the spring element by actuating the actuator the use position is displaceable. The grip element is thus displaced by spring force the use position and by the cable in the rest position. The cable thus counteracts the spring element. The invention has the advantage that the gripping element is always displaceable against the force of the spring element in the rest position, without the actuator has to be controlled / actuated for this purpose. As a result, the grip element can be displaced into the rest position at any time without the actuator being affected. Only the cable then loses its tension when publishing the grip element in the rest position. As soon as a force acting on the outside of the grip element, which displaces the grip element against the spring force into the rest position, disappears, the spring element urges the grip element back into the use position. Due to the fact that the grip element can be displaced into the rest position independently of the actuator, further design possibilities arise that improve the use of the grip element. Characterized in that the handle element at any time in the rest position independently of the actuator displaced is damage to the actuator safely avoided by the user. Alternatively or additionally, the invention provides that the grip element is formed in a circular arc and is mounted pivotably about a central axis of the circular arc shape of the valves. The circular arc-shaped design and the pivotable mounting results in a rotational movement of the handle element. Due to the circular arc shape is achieved that only a narrow recess, which must be formed only slightly larger than the cross section of the handle member, in a panel of the door is necessary. In addition, the handle offers due to its curvature in the use position for the user advantageous attack surface for mounting the door, as he can easily reach behind the handle. The handle itself requires no recess, so that the handle in the position of use can also differ from conventional handle elements design technology.

According to the invention it is provided that the handle element is assigned an unlocking device for unlocking the door, so that the user can easily unlock the door when needed. The handle device thus has means for unlocking the door, for example, from a frame of a motor vehicle body. The door expediently has a lock, by means of which the door can be locked in its closed position on the motor vehicle body. By providing an unlocking device on the handle element, the user can unlock the lock in a simple manner by means of the unlocking device. In particular, the unlocking device is designed such that the user can operate the handle element and the unlocking device with the same hand / operate.

Furthermore, the invention provides that the unlocking device has an actuating lever which is displaceable for actuating the unlocking device by the grip element when this is displaced by a user from the use position in the direction of the rest position. This results in the advantage that the door can be unlocked in a simple manner by the fact that the handle element displaced in the direction of the rest position, that is sunk into the door. Since this movement takes place independently of an actuation of the actuator, as already explained above, a user can bring about the unlocking of the door at any time by applying the gripping element with a corresponding force.

According to the invention it is provided that on the handle member, a carriage is arranged, which is displaceable between a release position and a driving position, wherein the carriage in a displacement of the grip element in
Direction of the rest position in the driving position against the actuating lever to its displacement and in the release position on the operating lever is passed over. This embodiment offers the advantage that depending on the position of the carriage, a displacement of the grip element in the rest position leads to a Endriegeln or not. In the driving position, the path of movement of the carriage leads to the handle element against the actuating lever, so that the carriage meets the actuating lever and this entrains in a further displacement of the handle member in the rest position and thereby actuates the unlocking device. Is the carriage in the release position, so leads the path of movement of the carriage past the operating lever so that it is not taken and thus the unlocking device is not operated.

It is preferably provided that the carriage is assigned at least one biasing spring, which urges the carriage in the driving position. This ensures that, normally, the unlocking device is actuated when the gripping element is displaced into the rest position and a door is unlocked. Conveniently, the unlocking device has means which ensure a displacement of the carriage in the release position, when an unlocking of the door when moving the grip member in the rest position is not desired. This is the case, for example, when the handle element is to be lowered into the door after the door has been closed.

According to an advantageous embodiment of the invention it is provided that the cable is attached to the carriage at one end and counteracts the biasing spring. The aforementioned means are thus realized in the present case that the cable mitbetätigt the carriage. If the actuator is actuated in order to displace the gripping element into the rest position, the cable pulls the carriage counter to the pretensioning force of the pretensioning spring so that the carriage is moved into the release position. Once the biasing spring is not further compressible and the cable is further pulled or rolled by the actuator, the entire handle element is displaced against the force of the spring element in the rest position on the carriage and the cable, due to the fact that the carriage in the release position the door is unlocked. In this way, a gripping device is provided with a displaceable gripping element, which is displaceable both for unlocking the door and without unlocking the door in the recessed rest position.

Furthermore, it is preferably provided that the gripping device has an end stop, up to which the gripping element can be displaced maximally by the spring element. The handle element is thus extendable out of the door up to the end stop. Since the extension or the movement of the grip element in the position of use by driving the actuator takes place by this does not pull the cable, but over a predetermined length releases (unrolls), the cable is relaxed as soon as the handle element has reached the end stop. If the cable is thus further relaxed by the actuator, as it is necessary for reaching the end stop, then according to the embodiment described above, the carriage is urged by the biasing spring into the driving position and the handle member is available for unlocking the door. By the end stop is so on simple manner allows a relaxation of the cable, which allows a relaxation of the biasing spring.

Furthermore, it is preferably provided that the carriage is displaceable at least substantially perpendicular to the displacement direction of the grip element. As a result, the slide can be moved particularly easily into a driving position in which the actuating lever can be actuated. In addition, it is achieved that the forces exerted by the cable on the carriage to move the handle member in the rest position, not only be introduced via the biasing spring in the handle member, but also by the storage of the carriage perpendicular to the latter shift direction. As a result, overstressing of the pretensioning spring is avoided and the service life of the gripping device is improved.

The object underlying the invention is also achieved by the door assembly having the features of claim 9. This is characterized by the handle device according to the invention. This results in the advantages already mentioned above. Other features and advantages will be apparent from the foregoing and from the claims.

FIGS. 3A and 3B

a detailed view of the handle device in different operating conditions.

Figures 1A and 1B show a door assembly 1 of a motor vehicle not shown here. The door assembly 1 has a door 2, of which only a portion of an outer panel 3 is shown. The outer lining 3 has a substantially rectangular handle recess 4. Behind the outer lining 3, so in the door 2, a handle device 5 is further arranged, which has a displaceable handle member 6, whose cross section substantially corresponds to the contour of the handle recess 4, so that the handle member 6 displaced by the handle recess 4 out of the door 2 out is. Figure 1A shows the grip element 6 in a rest position, in which an end face 7 of the grip element. 6 at least substantially flush with the outer panel 3, so that the grip element 6 fits in its rest position in the design of the outer panel 2. FIG. 1B shows the handle member 6 in a use position in which it is displaced by the handle recess 4 from the interior of the door 2, so that it protrudes from the outer panel 3 and is available for use. As in FIG. 1B already seen, the grip element 6 seen in longitudinal section or in the direction of movement on a circular arc shape, so that it is easily accessible and usable by the user outside the door 2. In contrast to conventional grip elements, the grip element 6 in the present case preferably has a continuous grip surface, or is formed by a break-through-free element. The grip element 6 is preferably made shell-like aluminum on the outside and provided on the inside with a rubber-like plastic, in particular with a non-slip surface, which facilitates the operation of the grip element 6 for the user.

FIG. 2 shows in a perspective view of the handle device 5 with the handle element 6. The handle device 5 has a headband 8, which is fastened or fastened to the inside of the outer lining 3 of the door 2 or to a frame part of the door 2. The headband 8 is frame-shaped and carries the grip element 6 and a device 9, which serves to displace the grip element 6. The handle element 6 has at its end facing away from the end face 7 on a support portion 10 which projects radially from the circular arc-shaped grip member 6 in the direction of the central axis of the circular arc shape. The support portion 10 extends to the central axis of the circular arc shape. There, the support portion 10 is rotatably mounted on a pin or a shaft 11 which is mounted in the headband 8. As a result, the grip element 6 is movable along the circular path, which corresponds to the circular arc shape of the grip element 6.

The device 9 has two spring elements 12, which are formed as expansion springs and are also arranged on the shaft 11. The spring elements 12 are formed as wire springs which are wound onto the shaft 11 and each have two free struts 12 ', 12 ", one of which abuts the support portion 10 and the other on the headband 8, wherein the spring elements 12 characterized the Handle element 6 with a spring force, which the grip element 6 about the shaft 11 and about the central axis of the circular arc around in the direction of the use position, as in FIG. 1B shown is pushing. The grip element 6 is pivotable up to a stop against the retaining clip 8 in its use position, so that the spring elements 12, the grip element 6 can not pivot beyond the use position. Conveniently, the Spring elements 12 are formed such that they are always biased between the support section 10 and bracket 8.

The device 9 furthermore has an actuator 13, which in the present case is designed as an electric motor. On the output shaft of the electric motor, a winding disk 14 is arranged, which is rotated by driving the electric motor 13. On the winding disk 14, one end of a cable 15 is attached, so that by operating the actuator 13 of the cable 15 on the winding disk 14 can be rolled up or unwound from this. The other end of the cable 15 is connected to the grip element 6. If the actuator 13 is actuated in order to wind up the cable pull 15, the handle element 6 is pivoted by the cable pull 15 against the force of the spring elements 12 into the rest position, in which the end face 7 is flush with the outer cover 3 of the door 2. If the actuator 13 is actuated in order to unroll the cable 15, ie release the cable, then the spring elements 12 move the gripping element 6 up to the stop defining the position of use on the mounting bracket 8. By actuating the actuator 13, the grip element 6 can be moved into any desired position Position spent between use position and rest position. In addition, a user can pivot the handle element 6 at any time into the door or relocate, without causing the actuator 13 is loaded. Rather, this would only lead to the cable 15 is relaxed. The user 6 only has to overcome the force of the spring elements 12. In the case of a maladjustment of the grip element, the actuator 13 is thus protected from damage, for example, and moreover, the grip element 6 can easily be displaced into the rest position in order, for example, to protect the user or the grip element 6 itself against damage.

The gripping device 5 furthermore has an unlocking device 16, by means of which the gripping element 6 can be used to unlock the door 2. As usual, the door 2 has a lock, by means of which it can be locked to a door frame of the motor vehicle. By means of the unlocking device 16, the lock can be unlocked, so that the door 2 can be mounted by the user. The unlocking device 16 has for this purpose an actuating lever 17, which is likewise mounted pivotably on the shaft 11. The actuating lever 17 is connected to a further cable 18, which is associated with the lock of the door 2, so stretched by displacing the actuating lever 17 about the pivot axis of the cable 18 and thereby the lock is unlocked.

FIGS. 3A and 3B show a detailed view of the unlocking device 16. On the grip element 6 or on the support portion 10 is approximately at the level of the grip element. 6 a deflection 19 arranged for the cable 15, as already in FIG. 2 shown. The cable 15 is guided around the deflection 19 so that it then extends at least substantially radially to the grip element 6 or parallel to the support portion 10. The end of the cable 15 is attached to a carriage 20 which is arranged displaceably or displaceably on the support portion 10. In this case, the carriage 20 in the present case is displaceable parallel to the support section 10 or radially to the circular arc shape of the grip element 6. The carriage 20 is held in a slide guide 21 on the support portion 10. In the slide guide 21 also two biasing springs 22 are arranged, which are presently designed as helical springs, and urge the carriage 20 in the direction of the pivot axis of the handle member 6, as indicated by an arrow 23. The biasing springs 22 urge the carriage 20 to a driving position defined by a stop 24 of the slide guide 21.

In the driving position, the carriage 20 is located on a movement path of the grip element 6, in which a free end 25 of the actuating lever 17 is located. If the grip element 6 is now pivoted in the direction of the rest position by the user, the carriage 20 hits the end 25 of the actuating lever 17 and takes it with it to actuate or unlock the lock of the door 2.

If the handle member 6 is pivoted by the actuator 13 in the rest position, so pulls the cable 15, the carriage 20 against the spring force of the biasing springs 22 (opposite to the direction of the arrow 23) in a release position, as in FIG. 3B is shown. In the release position, the entrainment is outside the trajectory in which it would meet the free end 25 of the actuating lever 17, so that it is shown in a displacing the grip member 6 in the rest position at the free end 25 and thus on the actuating lever 17, as in FIG. 3B shown. Because the biasing springs 22 further biased by the cable 15 and the carriage 20 has been moved to the release position, pulls the cable 15 via the deflection 19, the handle member 6 in the direction of rest position, the carriage 20 is guided past the actuating lever 17 and thereby the handle element 6 is moved / pivoted to the rest position, without the lock of the door is unlocked.

The advantageous handle device 5 thus provides a handle element 6, which is operable both for mounting the door 2 and for unlocking the lock of the door 2 by a user. Both to unlock the door and to bring the handle member 6 in the Rest position, the handle member 6 is moved in the direction of the rest position. If it is moved by the user 6, without the actuator 13 is driven, so takes the carriage 20 with the actuating lever 17 and the lock or the door 2 is unlocked. If the handle member 6 is pivoted by the actuator 13 in the rest position, the carriage 20 is moved to the release position and the handle member 6 spent without an actuation of the unlocking in the rest position.

If the actuator 13 is actuated in order to pivot the gripping element 6 into the use position, it is expediently activated in such a way that the gripping element 6 is pivoted up to the stop into the use position by the spring elements 12, and furthermore that the carriage 20 is moved by the pretensioning springs 22 is moved into the driving position. This ensures that after the removal of the handle member 6 in the position of use, the user is unlocked by moving the handle member 6 in the rest position, the door. In the use position of the cable 15 is thus preferably relaxed. In particular, a stop sensor is actuated in the use position by the grip element 6, which detects the control position of the actuator, the grip position. The actuator then rotates the winding disk or the cable bandage a little further, thus releasing the cable 15 a little further, whereby the carriage 20 is moved into the driving position by the biasing springs 22. When reaching the rest position, a further stop sensor is preferably actuated by the grip element 6, which gives the control of the signal for stopping and optionally for actuating an engine brake. The actuation of the actuator 13, for example, by actuation of a central locking of the motor vehicle. In particular, the actuator has an engine brake, which is released upon actuation of the central locking, and holds the cable 15 in its cocked position at rest without applying further energy.

To spend the operating lever 17 after its operation back to its initial position, this is suitably associated with a spring element 26 which is formed for example as a tension spring and on the one hand to the operating lever 17 and on the other hand fixed to the headband 8.

The provision and provision of the grip element 6 and the actuation of the unlocking device 16 thus take place via a rotational movement of the grip element 6. The narrow outlet contour of the grip element 6 reduces the necessary intervention in the door geometry and offers advantageous design freedom with respect to the positioning of the grip device 5 and in particular of the grip element 6 on the door 2. Preferably has the end face 7 of the grip element 6 also has an exchangeable aperture in order to advantageously insert the grip element 6 in its rest position into the design of the outer trim 3. As a result, the handle element 6 can be adapted by design to different surface profiles and / or colors of the outer lining of the door.

Because the spring elements 12 are always taut, the grip element 6 always strives to move into the position of use. The actuator 13 has only a damping and regulating function. In addition, the spring elements 12 give the user, upon actuation of the grip element 6 for unlocking the door, a counterforce as feedback, which allows the actuation of the unlocking to be sensed.

As an alternative to the exemplary embodiment illustrated here, it is also conceivable for the grip element 6 to be displaced or displaced in translation. Instead of an electric motor, the actuator 13 could also have a hydraulic or pneumatic drive. Instead of the pivot bearing on the shaft 11, it would also be conceivable to guide the grip element 6 by guide rails or to store, which are also circular arc-shaped and arranged on the retaining bracket 8.
