Lock device for a waste receiving device and waste receiving device with such a lock device

A lock device (1) for a waste receiving device (2) comprised of a container (3) that defines on an upper side a container opening enclosed by a container lip (4), and a cover (5) that is held on the container (3), said cover (5) being pivotably movable about a cover swivel axis (6) between a closed position that closes the container opening and an open position that uncovers the container opening, said lock device (1) comprising:

• an upper lock part (7) to be fastened on the cover, having each of
• an upper lock part housing (8),
• a locking mechanism (9) received in the upper lock part housing (8), and
• a first locking element (11) projecting downwards from the upper lock part housing (8) and being pivotable about a swivel axis (10) between a locking position and an unlocking position by actuating the locking mechanism (9);
• and
• a lower lock part (25) to be fastened on the container, having each of
• a lower lock part housing (26),
• a second locking element (30) projecting upwards from the lower lock part housing (26) and being pivotable about a swivel axis (29) between a blocking position and a release position, wherein said second locking element (30) cooperates in the blocking position with the first locking element (11) being in the locking position in such a way that the cover (5) is locked,
• a weight part (37) operatively connected to the second locking element (30), said weight part (37) being pivotably received in the lower lock part housing (26) to position the second locking element (30) in the blocking position when the container (3) is in the upright position, and is automatically transferred into the release position, in which the second locking element (30) is brought out of engagement with the first locking element (11) positioned in the locking position, when the container (3) is tilted forward for emptying, and
• a first arresting means (46) being movably received in the lower lock part housing (26), said first arresting means (46) arresting the second locking element (30) in the blocking position when the container (3) is in the upright position,
• wherein a second arresting means (44) is received movably in the lower lock part housing (26) and is arranged and formed to arrest the second locking element (30) in the blocking position when the container (3) is tilted laterally from the upright position,
• said second arresting means (44) comprising a ball that is movably guided within the lower lock part housing (26) in a T-shaped guide (43) that includes a substantially upright extending guide section (43a) and two guide sections (43b) branching off to both sides thereof at a lower end thereof and extending substantially laterally, the ball releasing the pivoting movement of the weight part (37) only when positioned at the upper end of the substantially upright extending guide section (43a).
