Abstract:
A container lock including an upper and a lower locking lug (1, 24) cap able of being passed into a respective lock groove (51, 53) in juxtaposed container corners (50, 52) and turned so as to lock therein in that the lower locking lug (24) is rotatably and translationally mounted in a housing (21) connected to the upper locking lug (1) and having a shaft (14) capable of limited movement in the axial direction, which is lock actuated by a spring (9) in the housing (21) in a downward direction, and between the housing (5, 21) and the shaft (14) there are arranged guide means (13, 8) which permit a locking rotation of the lower locking lug (24) on upward movement of the shaft (14), characterised in that the lower locking lug (24) is designed to have a pressure ball (25) intended for abutting interaction with a bottom of a lock groove (53) when an upper container is placed on a lower container, so that the housing (21) is thus pressed down onto the shaft (14), whereby a gap is formed between a downward facing circumferential annular surface on the shaft (14) and the lower part of the housing (21), and in that in the housing (21) there is arranged a locking device including spring actuated (31) locking arms (16, 17) which will move in towards the shaft (14) to a position in the gap below the circumferential annular surface and thus as a spacer prevent the return axial movement of the shaft (14).
