The handle 4 has a front side 19 and a rear side 20 arranged opposite the front side 19. In the first position of the handle 4, the back 20 abuts against the contact surface 14 of the end strip 13. As the Fig. 2 shows, in the first position of the handle 4, the front side 19 thereof is arranged flush with a front side 21 of the door 3, in particular the outer wall 10. As the Fig. 3 shows, in the second position of the handle 4, the front side 19 thereof is arranged perpendicular to the front side 21 of the door 3.

The door 3 further comprises a pivoting device 22, which is adapted to, in particular manual, moving the handle 4 of the in the Fig. 2 shown first position in the direction of in the Fig. 3 shown second position to pivot the handle 4 automatically in the second position. The pivoting device 22 comprises a spring element 23. The spring element 23 is preferably a cylindrical spring. In particular, the spring element 23 is a compression spring. The spring element 23 is operatively connected to the handle 4 in order to pivot it during displacement from the first position in the direction of the second position by means of a spring force in the second position. The spring element 23 is operatively connected to a second axis of rotation 24 of the handle 4.

The pivoting device 22 comprises a coupling element 25, which is coupled to the second axis of rotation 24 of the handle 4 and to the door 3 and which is adapted to transmit the spring force of the spring element 23 to the handle 4. In particular, the coupling element 25 is operatively connected to the base body 12 of the door 3. The pivoting device 22 further comprises a damping element 26 which is adapted to dampen a rotational movement of the handle 4 during pivoting thereof from the first position to the second position or vice versa. The damping element 26 may, as in the Fig. 2 and 3 shown to be a linear damper. Furthermore, the damping element 26 may be a rotary damper, which is arranged for example on the first axis of rotation 18 of the handle 4.

The 4 to 6 show the door 3 according to the Fig. 2 and 3 each in a schematic sectional view. The Fig. 4 shows the handle 4 in the first position. The Fig. 6 shows the handle 4 in the second position and the Fig. 5 shows the handle 4 in a position between the first and the second position. The following is on the 4 to 6 simultaneously referred to.

The coupling element 25 comprises a coupling rod 27 which is slidably received in a coupling sleeve 28. The coupling sleeve 28 is pivotably attached to the base body 12 at a rotational axis 29. As the Fig. 4 shows, the coupling rod 27 is retracted in the first position of the handle 4 approximately over the entire length of the coupling sleeve 28 in this. As the Fig. 6 shows, in the second position of the handle 4, the coupling rod 27 is at least partially pulled out of the coupling sleeve 28. The coupling rod 27 further includes a head 30 which is pivotally attached to the second axis of rotation 24 of the handle 4. The spring element 23 is arranged between the coupling sleeve 28 and the coupling rod 27. In particular, the spring element 23 is positioned between the coupling sleeve 28 and the head 30 of the coupling rod 27. In particular, the spring element 23 is attached to the coupling rod 27. That is, the coupling rod 27 extends inside the spring member 23.

The functionality of the handle 4 will be explained below. A spring force F of the spring element 23 acts in the direction of a central axis or axis of symmetry 31 of the coupling rod 27 or of the spring element 23 Fig. 4 shows, in the first position of the handle 4, the axes of rotation 18, 24 positioned to each other so that the spring force F causes a force acting on the handle 4 torque that rotates the handle 4 in a clockwise direction. The direction of rotation of the handle 4 is indicated by means of arrows 32, 33. In particular, the spring element 23 biases the handle 4 in the direction of the first position. That is, the spring force F presses the handle 4 against the end strip 13, in particular against the contact surface 14. In the first position of the handle 4, the first axis of rotation 18 between the second axis of rotation 24 and the contact surface 14 of the end strip 13 is arranged. The means, in the orientation of Fig. 4 shows a direction of action of the spring force F on the left side of the first axis of rotation 18 over.

When manually moving the handle 4 from the first position toward the second position shifts as in the Fig. 5 shown, the second axis of rotation 24 so relative to the first axis of rotation 18, that from an intermediate position, the spring force F, the handle 4 no longer clockwise, but counterclockwise rotates and the handle 4 automatically shifted to the second position. The Fig. 5 shows the handle 4 when pivoting from the intermediate position to the second position. In particular, in the intermediate position, the axes of rotation 18, 24 positioned so that the direction of action of the spring force F by both axes of rotation 18, 24 extends. In the intermediate position, both axes of rotation 18, 24 are arranged on the central axis 31. That is, in the intermediate position, a manual displacement of the handle 4 in the direction of the first position or in the direction of the second position causes the handle 4 to move automatically in the direction of the first or second position. The intermediate position is unstable, so that the handle 4 does not remain in the intermediate position.

In the second position of the handle 4 is in the orientation of the Fig. 6 the second rotation axis 24 is arranged to the right of the first rotation axis 18, so that the spring force F biases the grip 4 in the direction of the second position. In particular, in the second position, the second axis of rotation 24 between the first axis of rotation 18 and the contact surface 14 of the end strip 13 is arranged. To move the handle 4 from the second position to the first position, the handle 4 is displaced against the spring force F of the spring element 23 in the direction of the first position. From the intermediate position, that is, when the axes of rotation 18, 24 are both arranged on the central axis 31 and on the direction of action of the force F, the spring force F acts such that the handle 4 rotates clockwise. As a result, the handle 4 is pivoted to the first position. That is, the handle 4 is displaceable against the spring force F of the spring element 23 both from the first position and from the second position to the intermediate position.

Although the present invention has been described with reference to embodiments, it is variously modifiable.
