DESCRIPTION OF SPECIFIC EMBODIMENTS OF THE INVENTION

(11) FIGS. 1a to 1f show a handle device 10 according to the invention in a longitudinal section during the movement sequence of a handle part 20 from its rest position Ia through its operating position Ib into its trigger position Ic and back again. Consequently, FIGS. 1a and 1f are identical because they each show the handle part 20 in its rest position Ia. FIGS. 1c and 1e are also essentially identical because they also both show the handle part 20 in the operating position Ib. The handle device 10 according to the invention has the extendable handle part 20, which is supported in the handle support 11 in a movable manner. The handle support 11 serves to arrange the entire handle device 10 on a movable part 70, in particular a door, a flap or the like of a motor vehicle 100 (see e.g. FIGS. 6 and 7). The handle support 11 itself has an opening 12 whose internal dimensions are essentially complimentary to the external dimensions of the handle part 20. The opening 12 itself is provided with an edge 12.1 to make it difficult for unauthorized people to reach into the handle device 10, in particular into the interior 11.1 from the outside 11.2. The handle device 10 itself has a front side 10.1 and a rear side 10.2, wherein the fictitious planes of the front side 10.11 and rear side 10.2 have a minimum clearance that is to be referred to as an installation depth 10.3 within the meaning of the invention. The corresponding installation depth 10.3 is, for example, depicted in FIG. 3a. As can further be seen from FIGS. 1a to 1d, the handle part 20 initially moves out of the handle support 11 through the opening 12 in a linear manner (see arrow 50). The handle part 20 is guided by at least the two levers 13 and 14, which are referred to as the first lever 13 and the second lever 14. The first lever 13 has a fixed pivot point 13.1 with the handle part 12. The second lever 14 also has a fixed pivot point 14.1 with the handle part 20. However, the two pivot points 13.1 and 14.1 within the scope of the depicted installation situation from FIG. 1 are arranged such that they are offset vertically and laterally with respect to each other. The lever 13 is rotatably connected to the handle support 11 with its end that faces away from the handle part 20 via a further fixed (lower) pivot point 13.2. Thus, the first lever 13 makes only a rotary movement around the fixed pivot point 13.2 with the handle support 11. The second lever 14, however, has only the upper, fixed pivot point 14.1 with the handle part 20 and is equipped with an elongated hole 14.2 at its end that faces away from the handle part 20, the elongated hole 14.2 cooperating with a fixed pivot point 14.2 in the form of a bearing journal on the handle support 11 to impart a rotational pivoting movement in this area. The second lever 14 has an angle 14.4 with two ends at which the two pivot points are distally arranged relative to the angle 14.4. During the movement of the handle part 20 from the rest position Ia to its operating position Ib, the second lever 14 initially only rotates around the pivot point 14.2 or the bearing journal 14.2. Only after the handle part 20 has been transferred from its operating position Ib to its trigger position Ic does the second lever 14 make a vertical movement that is made possible by the elongated hole 14.2. The movement of the handle part 20 in particular from the operating position Ib to the trigger position Ic provides for mechanical cooperation between the second lever 14 and a further transfer lever 15, which can be seen clearly in FIG. 2.

(12) As already mentioned, the handle part 20 initially completes a linear movement 50 between the rest position Ia and the operating position Ib. When the handle part 20 moves further from the operating position Ib to the trigger position Ic, the handle part 20 transitions from the linear movement 50 to an arcuate (upward-oriented) movement 51 (see arrow 51). After the handle part 20 has been transferred to its trigger position Ic and a mechanical closing device 80 has been actuated by a connection element 16, the movable part 70 can be opened. To protect the handle device 10 in the interior 11.1 against external environmental influences insofar as possible, a seal 11.5 is provided along the circumference of the opening 12, in particular of the edge 12.1, the seal cooperating with the handle part 20 to close the opening 12. At the same time, the seal 11.5 can also be used as a guiding means 12.2 for the handle part 20. As can easily be seen in FIGS. 1c and 2c, a mechanical lock cylinder 27 is arranged on the handle support 11 next to the handle part 20. Usually, such a mechanical lock cylinder 27 is connected to the handle support 11 via a holder 27.1 or in a holder 27.1 (for the holder of the lock cylinder 27.1 see FIGS. 3 to 5).

(13) In FIGS. 1a, 1f as well as 2a and 2f, the handle part 20 is shown in the rest position Ia. In FIGS. 1b and 2b, the handle part 20 is shown in an intermediate position between the rest position Ia and the operating position Ib. In FIGS. 1c, 1e as well as 2c and 2e, the handle part 20 is in its operating position Ib. In FIGS. 1d and 2d, the handle part is shown in its trigger position 1c, the handle part 20 mechanically cooperating with the (purely) mechanical closing device 80 via the connection element 16, which is designed as a Bowden cable in the present case. The mechanical closing device 80 is indicated in FIGS. 6 and 7.

(14) As can further easily be seen in FIG. 1, the lever 13 can be provided with a counterweight 22 to increase the safety of the door handle device 10 according to the invention in accidents. At the same time, the point of application 13.4 for an additional or further connection element 29 that cooperates with a drive 19 can be provided on the counterweight 22. The drive 19 can be configured as an electric motor and be controlled by a control unit 25 of the handle device 10.

(15) In FIG. 1, the aforementioned drive 19 generates a pulling movement in the point of application 13.4 from lever 13 via the further connection element 29, which can in particular be designed as a Bowden cable. As a result, this lever 13 rotates counter-clockwise around its pivot point 13.2 and pushes the handle part 20 into its operating position Ib. If an operator wants to open the movable part 70, he must generate an arcuate rotary movement 51 of the handle part 20 to the trigger position Ic on the extended handle part 20 in the operating position Ib resulting in the lever 14 generating a vertical movement and rotating the transfer lever 15 around the fixed pivot point 15.1 from its rest position IIa to its trigger position IIb. In its rest position IIa, the transfer lever 15 hits against a stop of the handle support 11.

(16) The manner of operation of the transfer lever 15 can be seen more clearly in FIG. 2. As can easily be seen on the basis of FIGS. 2a to 2c, a movement of the handle part 20 from its rest position Ia to its operating position Ib does not initially cause a movement of the transfer lever 15 because a catch 14.5 of the second lever 14 simply slides along in the arcuate slot guide 15.2 of the transfer lever and the aforementioned freewheel is thus formed. Only when the catch 14.5 of the second lever 14 has reached the end of the arcuate guide 15.2 of the transfer lever 15 in the operating position Ib of the handle part 20 can a further movement of the handle part 20 towards its trigger position Ic cause the catch 14.5 to move onto the transfer lever 15. The transfer lever 15 is then rotated counter-clockwise around its fixed pivot point 15.1 by the catch 14.5 of the second lever 14 according to FIG. 2. As a result of this, the point of application 15.3 for the connection element 16 is moved upward, whereby a pulling force is imparted on the connection element 16. The transfer lever 15 is advantageously spring-loaded by an additional spring element, whereby, in principle, the transfer lever 15 is pulled into its rest position IIa. The mechanical cooperation between the second lever 14 and the transfer lever 15 is clearly apparent from FIGS. 2d to 2f. It also becomes clear that the second 14 rises to the pivot point 14.2 or pivot pin 14.2 due to its elongated hole 14.2.

(17) In FIGS. 3a, 3b and 3c, a further sectional view of the handle device 10 according to the invention is shown. The movement sequence of the handle part 20 from the rest position Ia through its operating position Ib into its trigger position Ic is shown. In this exemplary embodiment, a lighting unit 26 is arranged in the handle part 20 that can also optionally or additionally be arranged in the handle support 11. As can be seen on the basis of FIGS. 3b and 3c, the lighting unit 26 can emit a cone of light 26.1 to realize front field illumination. Once again, also apparent from FIGS. 3a to 3c is the manner of operation of the transfer lever 15, which cooperates with the connection element 16 for the mechanical closing device 80 via its point of application 15.3. The handle support 11 can additionally be provided with a panel 11.4 to elegantly cover the movable part 70 in the area of the handle device 10. Moreover, at least one holding means 11.3 is provided for the connection element 16 or 29 on the handle support 11. The corresponding holding means 11.3 for holding the connection element 16 on the handle support 11 can easily be seen in the sectional views of FIGS. 3a to 3c.

(18) Moreover, the handle part 20 has an outward-oriented cavity in which the various sensor elements 23, 24, etc. can be arranged, in particular behind a lid or panel. The aforementioned control unit 25 can also be housed in this cavity, as is shown in FIG. 3.

(19) In the rear view of the handle device 10 in FIG. 4, it can also easily be seen that the first lever 13 and the second handle 14 are U-shaped or H-shaped. The handle part 20 is bordered or held on both sides with the two parallel limbs of the U-shaped or H-shaped lever 13, 14. The upper pivot points 13.1 of the first lever 13 and the pivot point 14.1 of the second lever 14.1 can easily be seen. The lower pivot points of the two levers 13 and 14 are formed by the axles 13.3 and 14.3, which each have a continuous design. The axle 13.3, which simultaneously serves as a pivot point 13.2 for the lever 13, is provided with a first spring element 17 as a coiled spring, whereupon the first lever 13 is spring loaded, resulting in the handle part 20 being automatically pushed from its rest position Ia to its operating position Ib by the first spring element 17. From this operating position Ib, the handle part 20 can also be pulled back again by the further connection element 29, which cooperates with the drive 19.

(20) The rear view of a further embodiment of the handle device 10 according to the invention is shown in the further FIG. 5. A panel 11.4 is used for the handle support 11, the handle support 11 itself having grid structures for reinforcement. In addition, a crash barrier 21 is shown in FIG. 5 purely by way of example that can cooperate with the movement mechanism of the handle part 20 in a positive-locking manner to prevent an undesired movement of the handle part 20 in the event of an accident.

(21) A top view from the outside of a movable part 70 in the form of a car door is shown in FIG. 6. Here, a push button 28, or flap 28 or cap 28 is arranged next to the extendable handle part 20 above a mechanical lock cylinder 27, which is shown in dashed lines. By pressing this push button, flap or cap 28, the handle part 20 can also be unlocked in a purely mechanical manner and transferred from the rest position Ia to the operating position Ib by the first swing element 17. In addition, a security system 90, in particular in the form of a central locking mechanism, is shown in FIG. 6. This security system 90 can cooperate with a mobile ID transmitter 91, which is shown in FIG. 7, to achieve electronic authentication and unlock the central locking mechanism.

(22) A complete vehicle 100 having two handle devices 10 according to the invention on two movable parts 70 is shown in FIG. 7. The vehicle electronics 101 and the security system 90 are shown purely by way of example in the engine compartment in dashed lines.

(23) The foregoing explanation of the embodiments describes the present invention only in the context of examples. Of course, individual features of the embodiments, provided they are technically feasible, can be freely combined with each other without departing from the scope of the present invention.
