1. A beverage preparation machine (1) for brewed beverages, which comprises:
a housing (10) with a housing wall (11), which surrounds an inner space (10A) and has at least one opening (11A);
a brewing device (20) arranged in the inner space (10A) for producing a brewed beverage by brewing a quantity of a solid material, accommodated by the brewing device (20), with a brewing fluid, wherein the quantity of the solid material accommodated by the brewing device (20) is enabled to be output from the brewing device (20);
a movable container (30) for receiving a quantity of the solid material output from the brewing device (20), which container (30) is configured to be brought into the inner space (10A) through the opening (11A); and
a movable cover plate (50) for covering the opening (11A), wherein the cover plate (50) is configured to be brought at least into a first position (50A) and into a second position (50B) and is formed in such a way that in the first position (50A) it covers and/or closes at least one region of the opening (11A) and in the second position (50B) uncovers the opening (11A) in such a way that the container (30) is enabled to be moved through the opening (11A);
wherein the cover plate (50) is connected to the housing (10) via a pivoting device (65), so that the cover plate (50) is configured to be pivoted about a pivot axis (60) and by pivoting about this pivot axis (60) is movable between the first position (50A) and the second position (50B);
wherein the pivoting device (65) comprises a first lever arm (71), which is securely connected to the cover plate (50) and is mounted rotatably about the pivot axis (60);
wherein the pivoting device (65) has a second lever arm (72), which is rotatably mounted on the first lever arm (71), so that the second lever arm (72) is rotatable with respect to the first lever arm (71) about a rotation axis (75), which is arranged substantially parallel to the pivot axis (60) and at a distance from the pivot axis (60), wherein the pivoting device (65) comprises in addition a first guide device (80), which is formed to guide a first portion (72A) of the second lever arm (72) along a first guide curve (80A), wherein the first guide curve extends in such a way that the first portion (72A) of the second lever arm (72) on a pivoting movement of the cover plate (50) between the first position (50A) and the second position (50B) is moved along the first guide curve (80A); and
wherein a spring element (85) is arranged in such a way that a first portion of the spring element (85) is fastened to the second lever arm (72) at a distance from the rotation axis (75), and a second portion of the spring element (85) is fixed relative to the first lever arm (71) and/or to the housing (10).
