Abstract: A positioning element permits the panel or engine bonnet of a motor vehicle to be brought from the closed position into a position in which a gap forms between the upper edge of the opening and the lower edge of the panel. The panel can thus easily be unlocked and fully opened. The positioning element with inner lever and outer lever is connected to a drive component, which via the drive element and the drive pawl with a detent ensures that the panel is brought in a simple manner via the levers into the first raised position, for which purpose the detent is pushed into the recess of the outer lever and thus brings the outer lever and the inner lever into the first raised position. Once the panel has been brought by spring loading into the second raised position with the aid of the spring-loaded inner lever, the upward travel is completed, so that by means of the spring force associated with the outer lever, said outer lever then quickly pivots both levers back into the initial position.

Abstract: A door opening/closing mechanism fitted on a door that closes and opens an opening formed in the body of an apparatus by being brought into and out of contact with the rim of the opening has cam mechanisms that permit the door to engage with and disengage from the body at either of the right and left sides of the door (102). The cam mechanisms can be brought into a first lock position in which they lie symmetrically at both sides of the door and into a second lock position in which they lie symmetrically at both sides of the door, and each have a hinge pin (134) that serves as a rotation axis in the second lock position and a groove cam (141, 142) that engages with the hinge pin (134) in such a way as to be movable relative to the hinge pin. The groove cam (141, 142) has a slide portion (142b) on which a part of the innermost portion of the hinge pin slides when the cam mechanism is moved from the first lock position to the second lock position.

Abstract: A cam mechanism has different portions thereof arranged on a main unit and on a door. When the door is closed, a hinge pin is locked at one end of a hinge groove, keeping the cam mechanism in a first locked position. As the door is opened, the hinge pin is guided by the hinge groove and a guide pin is guided by a guide groove, permitting the door to rotate and slide. Thus, the hinge pin is locked at the other end of the hinge groove, bringing the cam mechanism to a second locked position. A boss slides on a rib and thereby maintains the second locked position, permitting the door to rotate about the hinge pin. This structure helps realize a door opening/closing mechanism with enhanced operability at reduced cost.
