Description

The present invention is directed to a device for a movable part, in particular a door, of a motor vehicle according to the preamble of claim 1. The handle device has a handle part for actuating the movable part, a carrier element for attaching the handle device to the movable part, the handle part being movably mounted on the carrier element between a rest position and an operating position, the handle part in the rest position being flush with an outer surface Outside of the movable part can be arranged, wherein the handle part can be moved out of an opening in the outside of the movable part in the operating position, and wherein the handle part can be operated in the operating position to open the movable part, and a drive unit is designed to move the handle part between to drive the rest position and the operating position.

Handle devices with flush handle parts that can be moved between a retracted rest position and an extended operating position are known in principle, such as. B. from the WO 2015/074020 . Known handle devices, however, have complicated drive units for driving the handle part which require a relatively large amount of installation space. Such drive units also allow a complicated sequence of movements of the handle part. However, this significantly reduces the comfort of such a handle device. With complicated drive units there is also the risk that the handle part can remain in one of the positions or in one of the intermediate positions and no longer function properly. If the handle part unintentionally remains in the operating position, it protrudes from the outside of the door in a disruptive manner. However, this means that the advantages of a flush handle device are lost.

It is therefore the object of the present invention to provide a handle device for a flush handle part which has a simple drive unit, stable operation and a high level of safety when driving the handle part. To achieve the above object, a handle device with the features of the main claim, in particular with the features from the characterizing part, is proposed. Further advantageous configurations of the invention emerge from the dependent claims, the description and the drawings.

According to the invention, the drive unit is designed in such a way that the outer surface of the handle part can always be moved parallel to the outside of the door between the rest position and the operating position of the handle part. In the context of the present application, the term: door is used for a movable part, a movable flap, a movable cover or the like. The carrier element can form part of a housing of the handle device and / or be designed as a frame structure and also serve as an assembly aid for the handle device on the movable part.

The idea of the invention is to create a simple drive unit with as few components as possible, which enables a simple, stable and trouble-free transfer of the handle part between the rest position and the operating position. As long as the outer surface of the handle part is moved parallel to the outside of the door, the risk of the handle part in one of the intermediate positions is advantageously reduced can persist. As a result, the path of travel of the handle part between the rest position and the operating position can be simplified, whereby the driving of the handle part can also be simplified. This also allows the drive effect to be transmitted stably to the handle part. The drive unit can manage with only one drive element, which can be a drive shaft or a drive rod, and with only one transmission element, in order to transmit the drive effect to the handle part simply and stably. In other words, the drive unit with only one transmission element between a drive shaft and the handle part can enable the movement of the drive element along the drive shaft, for example parallel to the outside of the door, into the movement of the handle part, for example essentially perpendicular to the outside of the door along a linear path or approximately perpendicular to the outside of the door along an arcuate path.

According to the invention it can be provided that the drive unit can have a linear drive. Such a drive unit generates a translational movement on a drive shaft or on a drive element, which is simple and stable and can transmit large drive forces. As a result of the linear drive, the drive unit can consequently produce the movement of the handle part along a predetermined travel path in a stable manner. The travel path can advantageously be shaped by a transmission link in the transmission chain of the drive action between the drive shaft and the handle part. It is conceivable that an arcuate movement of the handle part can be generated from a linear movement of the drive shaft. It is also conceivable that the linear movement of the drive shaft can be transformed into a likewise linear movement of the handle part offset by a certain angle, for example by 90 °. The drive unit with the linear drive can also generate a relatively large drive effect in a small installation space. In addition, the linear drive can generate different forces and thus allow different speeds when moving the handle part. The linear drive can be designed as a hydraulic, pneumatic or electromechanical drive.

Furthermore, it can be provided within the scope of the invention that the drive unit can have a drive element, in particular in the form of a drive rod. The drive element can serve as a movable part of the drive unit, which is driven in translation. It is advantageous that the drive element can stably transmit the drive action along a linear drive axis. In addition, it can be provided within the scope of the invention that the drive element can be moved linearly and parallel to the outside of the movable part and to the outside surface of the handle part. The installation space along the door can thus be utilized, with the installation space in the transverse direction to the door, which is often limited, can advantageously be reduced. As a result, the door can be made lighter and thinner, which simplifies the assembly of the door, makes the construction of the door lighter and simpler and increases the ease of use of the movable part.

Furthermore, it can be provided within the scope of the invention that the drive unit can have at least one transmission element in order to transmit the drive effect from the drive element to the handle part. The transmission element is meant as a single transmission link in the drive chain between the drive element and the handle part, which is designed to deflect the drive direction from the drive element and to transfer it to the handle part. It is advantageous here that an offset movement of the handle part, for example by an angle of approximately 90 °, can thus be generated from a linear movement of the drive element. Thus, from a simple and stable movement of the drive element, a redesigned, but nevertheless stable movement of the handle part can be generated.

In addition, the invention can provide that the drive unit can have two transmission elements which can engage the drive element at the end. This means the same transmission link in the drive chain, which can be designed twice. The two transmission elements enclose the handle part symmetrically on the two end sides of the handle part. Both transmission elements act synchronously as the same transmission link in the drive chain and rather serve to create two symmetrical points of application on the drive element and also two symmetrical points of application on the handle part in order to carry out the transmission effect from the drive element to the handle part on both sides and thus stabilize it. It is advantageous here that with the aid of two transmission elements arranged at the ends, even an elongated handle can be driven evenly and thus without interference.

Furthermore, the invention can provide that a connecting element, for example in the form of a connecting rod, can be provided between the two transmission elements in order to synchronize the movement of the transmission elements. The connecting element can extend like a conductor bar between the transmission elements and be oriented essentially parallel to the outside of the door and to the outside surface of the handle part. The connecting element can advantageously even out the transmission effect from the drive element to the two transmission elements and the movement of the two transmission elements. The connecting element can partially imitate the movement of the handle part in that the connecting element can be moved essentially parallel to the outside of the door. In addition, the invention can provide that the connecting element can be mounted pivotably about a fourth axis that can be moved with the first transmission element and with the second transmission element. It is advantageous that the angle between the drive element and the transmission elements, as well as between the transmission elements and the connecting element, can be changed when the drive effect is transmitted from the drive element to the handle part.

According to the invention it can also be provided that the at least one transmission element can be mounted on the drive element so as to be pivotable about a first axis movable with the drive element and / or pivotably about a second axis movable with the handle part on the handle part. As a result, a transmission chain of the drive action with a variable angle between the drive element and the transmission element and between the transmission element and the handle part can advantageously be created. The installation space along the outside of the door can be used to execute a linear movement of the drive element parallel to the outside of the door. By means of the pivotable transmission element, this movement can then even be deflected in a small installation space in the transverse direction to the outside of the door, so that the handle part can move out of the opening in the door essentially perpendicular to the outside of the door.

According to the invention, the drive element also has at least one stop surface which can be brought into operative connection with the handle part in an emergency, to support the drive effect on the handle part. In normal operation, however, the stop surface is without any operative engagement with the handle part. The advantage here is that in an emergency, for example when the handle device freezes, an additional and direct contact surface can be created between the drive element and the handle part in order to increase the drive effect on the handle part and avoid any ice in a gap between the Break opening in the door and the outer surface of the handle part.

Furthermore, it can be provided within the scope of the invention that the handle part can have at least one emergency element, which in an emergency can be brought into operative connection with the stop surface in order to support the drive effect on the handle part, in particular in a normal case the emergency element from the Stop surface is spaced. Here, the transmission element can have an elongated hole at the point of application to the drive element in order to implement a certain lag for the drive element in the event of the handle part freezing in the opening in the movable part until the stop surface of the drive element can be brought into operative engagement with the emergency element of the handle part . An ice-breaking function can thus advantageously be implemented with the aid of the handle device according to the invention.

According to the invention, it is also conceivable that the at least one transmission element can be designed in the form of a straight or curved lever. Such a component is inexpensive to manufacture and easy to assemble. A straight transmission element is particularly stable when it is driven, and a curved transmission element can advantageously reduce the installation space required for the transmission of the drive effect.

Furthermore, it can be provided within the scope of the invention that the carrier element can have at least one guide slot in order to stabilize the movement of the handle part between the rest position and the operating position. The movement of the handle part can thus be predetermined by the shape of the guide link and serve as an additional guide to the transmission mechanism through the drive unit. It is also conceivable that the carrier element can have two guide slots in order to support the movement of the handle part from two end sides. As a result, the stability in the guidance of the handle part can be increased even further.

In terms of the invention, it is also conceivable that the at least one guide slot, in particular the two guide slots, can be designed in such a way that the handle part can move essentially perpendicular to the outside of the movable part and to the outer surface of the handle part. Thus, the handle part can have a direction of movement essentially perpendicular to the outside of the movable part. As a result, the transfer of the handle part between the rest position and the operating position can be carried out in a stable and controlled manner. According to the invention it can also be provided that the at least one guide slot, in particular the two guide slots, can be aligned perpendicular to the outside of the movable part and to the outer surface of the handle part. Thus the at least one guide slot, in particular the two guide slots, can be produced easily and with little effort. The simple sequence of movements of the handle part within the meaning of the invention can be implemented in a simple manner by such guide slot or guide slot, which enables a stable and reliable transfer of the handle part between the rest position and the operating position.

It is also conceivable that the handle part can have a cam, in particular two cams, which can engage in the guide slot, in particular in the two guide slots. A simple and safe interaction of the guide link and the handle part can thus be made possible.

Furthermore, the invention can provide that the carrier element can have at least one stop element in order to limit the movement of the handle part laterally and / or to the rear between the rest position and the operating position. It is advantageous here that the stop element cannot accidentally carry out an undesired movement of the handle part outside the specified travel path. This also avoids the risk that the carrier element can stop during the movement. Furthermore, it is also conceivable that the carrier element can have two stop elements in order to support the movement of the handle part from two end sides. As a result, the movement of the handle part can be carried out in an even more stable and secure manner. Furthermore, the carrier element behind the handle part can have one, two or three Have stop elements in order to prevent the handle part from moving in beyond a rest position.

Furthermore, it can be provided within the scope of the invention that the drive unit can be designed to be self-locking. This has the advantage that the handle part can be protected against abrupt slamming or unwanted knocking out, at least in the operating position. In this way, unwanted and excessive actuation of the handle part can be prevented. It can be provided that the drive element and the transmission element can be aligned almost perpendicular to one another in the operating position of the handle part in order to prevent an unintentional transfer of the handle part from the operating position to the rest position. As a result, the drive element and the transmission element can form a T-piece which is prevented from abruptly striking the transmission element against the drive element. The T-piece can, however, be released again by a deliberate and moderate actuation of the handle part or the drive unit in the sense of the invention in order to transfer the handle part from the operating position to the rest position. In the rest position of the handle part, the drive element and the transmission element can then be arranged at an acute angle to one another.

According to the invention, it is conceivable that the drive element and the at least one transmission element in the operating position of the handle part at an angle of 75 ° to 90 °, in particular 80 ° to 88 °, preferably 84 ° to 86 °, can be aligned to each other to prevent unwanted transfer to prevent the handle part from the operating position to the rest position. Such an angle is advantageously close enough to 90 ° to block a loosening of their alignment essentially perpendicular to one another by the transmission element striking the drive element. Such an angle can, however, advantageously allow a deliberate and moderate actuation of the handle part or the drive unit in the sense of the invention in order to move the handle part from the operating position into the rest position.

Furthermore, the invention can provide that at least one spring element, in particular two spring elements, can be provided in order to support the movement of the handle part from the operating position into the rest position. Thus, advantageously a Release the alignment of the drive element to the transmission element essentially perpendicular to each other, or in other words a release of a T-piece between the transmission element and the drive element can be supported by spring force in order to release the self-locking of the drive unit in the operating position in a flexible manner against careful actuation.

A first spring element can strike the drive element in order to load the drive element from an extended position into a retracted position, the handle part being in the rest position in the retracted position of the drive element and the handle part being in the operating position in the extended position of the drive element . As a result, the drive element can be acted upon in the moved-in position in order to ensure that the handle part can be driven over into the rest position by moderate actuation, even despite a self-locking effect of the drive unit.

Furthermore, it can be provided that a second spring element can strike the handle part in order to load the handle part from the operating position into the rest position. This has the advantage that the handle part can safely move from the operating position into the rest position via a slow, deliberate actuation and cannot remain in the extended operating position.

It is also conceivable that the at least one transmission element can be designed in the form of a triangle. This can achieve the advantage that the transmission element can have three points of attack in order to attack the drive element with one point of attack, to attack the handle part with the second point of attack and finally to form a pivotable axis with a third point of attack, which is used to pivot the transmission element on the carrier element can serve. The pivotable axis can advantageously serve as a support point for the transmission element on the carrier element. Thus, the transmission element can be driven more stably and securely and even the driving effect can be transmitted more stably to the handle part. As a result, the linear movement of the drive element can initially be converted into an arcuate movement of the transmission element finally to enable a corresponding movement of the handle part essentially perpendicular to the outside of the door.

Furthermore, it can be provided within the scope of the invention that the at least one transmission element can have one, in particular one, elongated hole for the drive element in order to receive a first axis movable with the drive element in a linearly movable and pivotable manner. This enables several advantages to be achieved. On the one hand, it can thus be made possible that a linear movement of the drive element can be transformed into an arcuate movement of the transmission element in that the transmission element can engage the drive element with a variable radius along the elongated hole. On the other hand, it can be ensured that in the operating position of the handle part there can still be some leeway along the elongated hole in order to be able to pull the handle part a little further outwards from the opening in the outside of the door when the drive element and transmission element are stationary, and to e.g. to open the door. It can thus be realized that in the operating position of the handle part, the handle part can be moved in order to be operated to operate the door.

According to the invention, it can also be provided that the at least one transmission element can be mounted on the carrier element so as to be pivotable about a, in particular, a third fixed axis. Thus, the transmission element can be supported with a point of application on the carrier element in order to safely transfer the drive effect to the handle part.

Furthermore, the invention can provide that the at least one transmission element can have one, in particular one, elongated hole for the handle part in order to accommodate a second axis movable with the handle part in a linearly movable and pivotable manner. Thus the advantage can be achieved that the arcuate movement of the transmission element can be transformed into a linear movement of the handle part from the rest position into the operating position and vice versa. A linear movement of the handle part is advantageous because it can be supported easily and securely on the carrier element, for example with the aid of a guide link, and because it is least susceptible to failure.

Furthermore, it is conceivable within the meaning of the invention that the carrier element can have at least one stop guide to laterally stabilize the movement of the handle part between the rest position and the operating position, wherein in particular the carrier element can have two stop guides to move the handle part from two end sides to support. As a result, at least one continuous stop can be created on one end side or on two end sides of the handle part in order to ensure that the handle part does not deflect to the side and can safely follow the specified travel path.

Furthermore, it can be provided within the scope of the invention that the handle part can have a sensor in order to automatically initiate opening of the movable part when a user reaches into a recessed grip on the handle part with one hand. A simple and intuitive operation of the door can thus be made possible, which can be carried out completely automatically without pulling on the handle part. In addition, it can be provided within the scope of the invention that the handle part can have a switch on the outer surface in order to automatically initiate a transfer of the handle part from the operating position to the rest position. A user would want to operate the point on the outer surface of the handle part intuitively in order to drive in the handle part. Furthermore, it can be provided within the scope of the invention that the handle part can have a sensor, for example on an upper flat side, in order to automatically initiate locking of the movable part by tapping on the sensor. The door can be locked easily and transparently by tapping on the top of the handle. The actuation of the handle part can thus be fully automated, with the corresponding sensors and switches being able to be positioned at points which the user can intuitively find for the respective action. The operation of the handle device can thus be made even more convenient.

According to the invention, the handle device can be designed as a component of a keyless go system of a motor vehicle, which can lock and / or unlock the movable part in particular without a mechanical lock cylinder. Thus, an automatic system can be provided to unlock or lock the motor vehicle without actively using a car key. One automatically out and the handle part moving in can advantageously increase the ease of use of the motor vehicle.

Furthermore, it is conceivable that the handle device can have a transmitting and receiving unit in order to carry out an authorization query for a user. The authorization of a user who is about to operate the handle device can thus advantageously be verified directly on the handle device. It is conceivable that the transmitting and receiving unit can be arranged directly in the movable handle part or can be installed in a stationary manner on the carrier element.

The Figures 1a to 3 show a device 10 according to the invention with a flush handle part 11 in a rest position I. The handle part 11 is used according to the invention to operate, for example. To open, a movable part, such as. B. a vehicle door. The handle device 10 is fastened to a carrier element 12, which can serve as a housing or as a frame structure for fastening the handle device 10 to the movable part. In order to finally be able to operate the handle part 11, the handle part 11 is between a drive unit 20 in the Figure 1a and the Figure 2a shown flush rest position I and one in the Figure 2e and the Figure 3 operating position II shown drivable. As from the Figure 1a As can be seen, the handle part 11 is in the rest position I with an outer surface 11a flush with an outer side 100 of the movable part. In the operating position II, which is in the Figures 2e and 3 As shown, the handle part 11 is made up of an opening 101 in the outside 100 of the movable part moved out, wherein the handle part 11 can be operated in this extended operating position II to open the movable part. It is conceivable that the handle part 11 can be pulled a little further out of the opening 101 in the outer side 100 of the movable part in order to open the movable part. Alternatively, however, it is also conceivable that the handle part 11 can have a contactless, for example capacitive sensor 16, the monitoring area of which can be aligned in a recessed grip 11d on the handle part 11 in order to automatically open the movable part by reaching into the recessed grip 11d.

The drive unit 20 according to the invention is designed such that the outer surface 11a of the handle part 11 is always moved parallel to the outer side 100 of the movable part between the rest position I and the operating position II of the handle part 11. The drive unit 20 comprises a drive element 21 in the form of a drive shaft or a drive rod and only one double transmission element 22.1, 22.2 in order to transmit the drive action from a linear drive 23 to the handle part 11 simply and stably. The double transmission element 22.1, 22.2 forms a single transmission element between the drive element 21 and the handle part 11. The linear drive 23 generates a translational movement of the drive element 21 along the line L1, which is parallel to the outer side 100 of the movable part and parallel to the outer surface 11a of the handle part 11 extends. A translational movement along the outside 100 of the movable part makes it possible to utilize the installation space along the outside 100 of the movable part and to reduce the installation space perpendicular thereto, which is tightly dimensioned. The drive element 21 can be moved between a retracted position 1, which is in the Figures 1a and 2a is shown, and move to an extended position 2, which is in the Figures 2e and 3 is shown. In the retracted position 1 of the drive unit 21, the handle part 11 is in the rest position I and in the extended position 2 of the drive unit 21, the handle part 11 is in the operating position II. The sequence of movements of the drive unit 20 and the travel L3 of the handle part 11 is described below based on Figures 2a to 2e explained.

According to the invention, the drive unit 20 can manage with only one transmission element 22.1, 22.2 in order to transmit the drive effect from the drive element 21 to the handle part 11. Two symmetrically arranged transmission elements 22.1, 22.2 advantageous in order to transfer the drive effect to the handle part 11 on both sides and thus enable a stable, predetermined travel path L3 of the handle part 11 between the rest position I and the operating position II. A first transmission element 22.1 is arranged on the left and a second transmission element 22.2 on the right of the handle part 11. Both transmission elements 22.1, 22.2 represent the same transmission link in the drive chain according to the invention, which is only designed twice in order to enclose the handle part 11 on both sides. Both transmission elements 22.1, 22.2 act synchronously with one another and serve to create two symmetrical points of application A1, A2 on the drive element 21 in order to tap the drive action. The transmission elements 22.1, 22.2 are each pivotably connected to the drive element 21 on a first axis A1, A2. Both transmission elements 22.1, 22.2 also serve to create two symmetrical points of application B1, B2 on the handle part 11 in order to symmetrically transmit the drive effect from the drive element 21 to the handle part 11 and thus stabilize it. The transmission elements 22.1, 22.2 are each connected to the handle part 11 on a second pivotable axis B1, B2. It is advantageous that with the aid of two transmission elements 22.1, 22.2 arranged at the ends, even an elongated handle part 11 can be driven uniformly and thus without interference. Due to the pivotable connection between the drive element 21 and the respective transmission element 22.1, 22.2 and between the respective transmission element 22.1, 22.2 and the handle part 11, the drive effect can be transmitted at a variable angle. In the embodiment of Figure 1a a linear movement of the drive element 21 along the line L1 is transformed into an arcuate movement L2 of the respective transmission element 22.1, 22.2 and finally into a linear movement L3 of the handle part 11 perpendicular to the outside 100 of the movable part.

The transmission element 22.1, 22.2 according to the embodiment of Figure 1a is designed in the form of a straight lever, wherein the transmission element 22.1, 22.2 can also be designed as a curved transmission element 22.1, 22.2, as in the embodiment of Figures 4a and 4b is shown below, for example. To reduce the required installation space in the direction perpendicular to the outside 100 of the movable part.

The carrier element 12 of the handle device 10 according to the invention is according to the exemplary embodiment Figure 1a formed with two symmetrical guide slots 13.1, 13.2 in order to support and thus stabilize the movement of the handle part 11 between the rest position I and the operating position II on both sides. However, it would also be conceivable that only one guide link 13.1., 13.2 could be sufficient to support the linear movement of the handle part 11. The guide links 13.1, 13.2 are also in the Figure 1b shown in a front view of the opening 101 in the outside 100 of the movable part, from which the handle part 11 can move out into its operating position II. The guide links 13.1, 13.2 are aligned perpendicular to the outer side 100 of the movable part and to the outer surface 11a of the handle part 11 and help ensure that the movement of the outer surface 11a of the handle part 11 between the rest position I and the operating position II is always parallel to the outer side 100. A cam 11.1, 11.2 acts together with the respective guide slot 13.1, 13.2, which is formed under the handle part 11 and can engage in the respective guide slot 13.1, 13.2.

How it continues in the Figure 1a is shown, the carrier element 12 can be designed with several stop elements 12.1, 12.2, 12.3, 14.1, 14.2 in order to move the handle part 11 with the help of lateral stop elements 14.1, 14.2 to the sides of the handle part 11 and with the help of rear stop elements 12.1, 12.2, 12.3 to limit to the rear. In further embodiments of the invention, which are shown in the Figures 5 to 10 are shown, further stop elements 12.4, 12.5 can be provided below the handle part 11 on the carrier element 12 in order to facilitate sliding of the handle part 11 on the carrier element 12 by reducing the contact area between the handle part 11 and the carrier element 12 on the stop elements 12.4, 12.5 .

The Figure 1c shows a further embodiment of the invention with a highlighted stop surface 21b on the drive element 21, which in an emergency, for example when the handle 11 freezes within the opening 101, can be brought into operative connection with an emergency element 11b on the handle 11 in order to transfer the handle 11 from the rest position I to the operating position II. In a normal case, which is in the Figure 1c however, the emergency element 11b is spaced from the stop surface 21b. Here, the respective transmission element 22.1, 22.2 is formed at the point of application A1, A2 to the drive element 21 with an elongated hole 22.3, 22.4 in each case in order to, in the case of a Freezing of the handle part 11 in the opening 101 on the movable part to realize a certain lag for the drive element 21 until the stop surface 21b of the drive element 21 can be brought into operative engagement with the emergency element 11b of the handle part 11. Thus, for example, an ice-breaking function can be implemented in that the drive effect can also be transmitted to the emergency element 11b of the handle part 11 via the stop surface 21b of the drive element 21. The respective elongated hole 22.3, 22.4 also has the advantage that the handle part 11 can be pulled a little further out of the operating position II in order to cause the movable part to open.

The Figures 2a to 2e show the sequence of movements of the handle part 11 between the rest position I and the operating position II according to the embodiment of the handle device 10 according to FIG Figure 1a . The drive element 21 is driven linearly along the line L1. In the Figure 2a the drive element 21 is in its moved-in position 1. The drive element 21 and the transmission element 22 are arranged at an acute angle to one another. Between the position according to the Figure 2a and the position according to the Figure 2e the drive element 21 moves from left to right to its outermost position or to its extended position 2. While the drive element 21 moves from left to right, the transmission elements 22.1, 22.2 are moved along the arrow L2 about the respective first axis A1, A2 pivoted downwards, so that the handle part 11 from above from its rest position I according to FIG Figure 2a down into the operating position II according to the Figure 2e can move linearly along line L3. The deflection of a pivotable movement of the transmission element 22.1, 22.2 into a linear movement of the handle part 11 is possible due to a pivotable connection between the transmission elements 22.1, 22.2 and the handle part 11 on the respective second axis B1, B2. Furthermore, the guides 13.1, 13.2 on the carrier element 12 at least partially support the translational movement sequence of the handle part 11 along the line L3.

The Figure 3 shows the handle part 11 according to the invention in the operating position II. It can be seen that the drive element 21 and the transmission element 22.1, 22.2 are aligned almost perpendicular to one another in the operating position II of the handle part 11. Such an alignment of the drive element 21 to the transmission element 22.1, 22.2 prevents an unintentional abrupt transfer of the handle part 11 from the operating position II to the rest position I. The drive unit 20 acts in a self-locking manner against an abrupt impact of the transmission element 22.1, 22.2 on the drive element 21. It is conceivable that an angle α between the drive element 21 and the transmission element 22.1, 22.2 in the operating position II of the handle part 11 can be close to 90 °, for example between 75 ° to 90 °, in particular 80 ° to 88 °, preferably 84 ° to 86 °. Such an alignment of the drive element 21 to the transmission element 22.1, 22.2 can only be released again by a deliberate and moderate actuation of the handle part 11 or the drive unit 20 in the sense of the invention. Such a sequence of movements can backwards from the position according to FIG Figure 2e back to the position according to the Figure 2a be carried out in order to transfer the handle part 11 from the operating position II into the rest position I.

Furthermore, the Figure 3 that a first spring element 15.1 can be provided on the drive element 21 to move the drive element 21 out of the extended position 2 according to FIG Figure 3 or the Figure 2e into the retracted position according to Figure 1a or the Figure 2a to apply. It can thereby be ensured that the drive element 21, despite an almost perpendicular alignment to the transmission element 22.1, 22.2, is nevertheless moved into the moved-in position 1 according to FIG Figure 1a or the Figure 2a can be run over. In addition, the Figure 3 that a second spring element 15.2 can be provided on the handle part 11 in order to act on the handle part 11 from the operating position II into the rest position I. This ensures that the handle part 11 can be driven over from the operating position II into the rest position II by means of a slow, deliberate actuation, despite the self-locking alignment of the drive element 21 with the transmission element 22.1, 22.2. For this purpose, it can be provided according to the invention that the handle part 11 can be transferred manually from the operating position II to the rest position II, for example by pressing the handle part along the arrow -L3. Alternatively, however, it is also conceivable that a switch 17 can be provided which can be actuated in order to automatically transfer the handle part 11 from the operating position II to the rest position II. Such a switch 17 is exemplified in Figures 3 , 7th and 10 shown.

Furthermore, the Figures 3 , 7th and 10 that the handle part 11 can have a contactless, for example capacitive sensor 16 in order to open the movable part initiate automatically when a user reaches into the recessed grip 11d on the handle part 11 with one hand. A simple and intuitive operation of the movable part can thus be made possible, even without pulling on the handle part 11. In addition, the handle part 11 can have a further contactless sensor 18, for example on an upper flat side 11c, so that by tapping lightly on the sensor 18 or by a simple approach to the sensor 18 to automatically initiate a retraction of the handle part 11 and a locking of the movable part. The actuation of the handle part 11 can thus be fully automated and the operation of the handle device 10 can be made more convenient. It is conceivable that the handle device 10 can be part of a keyless go system of a motor vehicle, which can lock and / or unlock the movable part in particular without a mechanical lock cylinder. Thus, an automatic system can be provided to unlock or lock the movable part without active use of a car key. A handle part 11 according to the handle device 10 according to the invention that moves in and out automatically can increase the ease of use of the movable part even further. It is conceivable that the handle device 10 can have a transmitting and receiving unit 19, for example on the carrier element 12, in order to carry out an authorization query for a user. In this way, the authorization of a user who approaches to open the movable part can advantageously be queried directly in the vicinity of the handle part 11.

The Figures 4a and 4b show a further embodiment of the handle device 10 according to the invention, according to which the transmission elements 22.1, 22.2 can be designed curved. As a result, the installation space of the handle device 10 can be reduced in the direction perpendicular to the outside 100 of the movable part, which is mostly tightly dimensioned. They also show Figures 4a and 4b that between the two transmission elements 22.1, 22.2 a connecting element 23 in the form of a connecting rod can be provided in order to synchronize the movement of the transmission elements 22.1, 22.2. The connecting element 23 can be aligned essentially parallel to the outer side 100 of the movable part and to the outer surface 11 a of the handle part 11. The connecting element 23 ensures that the drive effect is uniformly transmitted from the drive element 21 to the two transmission elements 22.1, 22.2. The connecting element 23 can partially the movement of the handle part 11 according to the Figures 2a to 2e imitate by the connecting element 23 in Is moved downward essentially parallel to the outside 100 of the door. The connecting element 23 is mounted pivotably about a fourth axis D1, D2 with the first connecting element 22.1 and with the second connecting element 22.2.

The Figure 5 shows a further embodiment of the handle device 10 according to the invention, according to which the at least one transmission element 22.1, 22.2 is designed in the shape of a triangle. The transmission element 22.1, 22.2 can thus form three points of attack in order to attack the drive element 21 with a point of attack A1, A2, to attack the handle part 11 with a second point of attack B1, B2 and finally to a fixed axis C1, C2 with a third point of attack C1, C2 form, which can be used to pivot the transmission element 22.1, 22.2 on the carrier element 12. The third axis C1, C2 can serve as a support point for the transmission element 22.1, 22.2 on the carrier element 12. Thus, the transmission element 22.1, 22.2 can be driven in a more stable and secure manner and the drive effect can consequently be transmitted to the handle part 11 in a more stable and secure manner. According to this embodiment of the handle device, the linear movement of the drive element 21 can be transformed into an arcuate movement L2 of the transmission element 22.1, 22.2.

In the embodiment according to Figure 5 the handle part 11, as shown in FIG Figures 6a to 6b , also moved in an arc shape L3, in each position of the handle part 11 between the rest position according to the Figure 6a and the operating position II according to the Figure 6e the outer surface 11a of the handle part 11 is always moved parallel to the outer side 100 of the movable part. As a result, the grip part 11 can be avoided. At the point of application A1, A2, the respective transmission element 22.1, 22.2 is formed with an elongated hole 22.3, 22.4 for the drive element 21 in order to accommodate the first axis A1, A2 movable with the drive element 21 in a linearly movable manner in the elongated hole 22.3, 22.4 and pivotably. This enables a linear movement of the drive element 21 to be transformed into an arcuate movement L2 of the transmission element 22.1, 22.2. In this exemplary embodiment, the guide links 13.1, 13.2 can be dispensed with so that the handle part 11 can execute the arcuate movement L3 between the two stop elements 14.1, 14.2.

The Figure 7 finally shows the handle part 11 in the operating position II according to FIG Figure 6e . By moving the drive element 21 back along the arrow -L1, the drive element 21 can move from the extended position 2 back into the extended position 1 according to FIGS Figures 5 and 6a are proceeded. The handle part 11 can be actuated manually by pressing along the arrow -L3 or automatically with the aid of a switch 17. In this embodiment, too, a sensor 16 for automatically opening the movable part and a sensor 18 for automatically retracting the handle part 11 and for locking the movable part can be provided.

How to do it with the help of the Figures 8 to 10 is shown, the invention can provide a further embodiment of the handle device 10 according to the invention, according to which the at least one transmission element 22.1, 22.2 can have one, in particular one, elongated hole 22.5, 22.6 for the handle part 11, around the second B1, B2 with the handle part 11 movable axis linearly movable in the elongated hole 22.5, 22.6 and swiveling. Thus, the arcuate movement L2 of the transmission element 22.2, 22.2 can be transformed into a linear movement L3 of the handle part 11 from the rest position I into the operating position II, as the Figures 9a to 9e demonstrate. A linear movement L3 of the handle part 11 can be supported easily and safely on the carrier element 12, for example with the aid of a guide slot 13.1, 13.2 or a stop guide 14.2. A linear movement L3 of the handle part 11 is also advantageous because it is least susceptible to failure. The stop guide 14.2 according to Figures 9a to 9e can, together with the stop element 14.1, limit the movement of the handle part 11 from two end sides and thus support it. As a result, at least one continuous stop can be created on one end side of the handle part 11.

The Figure 10 finally shows the handle part 11 in the operating position according to FIG Figure 9e . By moving the drive element 21 back along the arrow -L1, the drive element 21 can move from the extended position 2 back into the extended position 1 according to FIGS Figures 8 and 9a are proceeded. The handle part 11 can be actuated manually by pressing along the arrow -L3 or automatically with the aid of a switch 17 in order to move from the operating position II back into the rest position I. In this embodiment, too, a sensor 16 can be used to automatically open the movable part and a sensor 18 can be provided for automatically retracting the handle part 11 and for locking the movable part.
