Systems, methods, and apparatuses are disclosed for locking mechanisms to secure multiple cart components. Example embodiments may include a cart with a lower platform, an upper platform, a first storage area disposed between the lower platform and the upper platform, and a second storage area disposed adjacent to the upper platform. Some embodiments may include a door configured to secure the first storage area, where the door is configured to rotate outwards with respect to the upper platform, a hatch configured to secure the second storage area, where the hatch is configured to rotate upwards with respect to the upper platform, and a locking mechanism coupled to the upper platform and configured to lock both the hatch and the door in a locked position. Unlocking the locking mechanism can unlock both the first access panel and the second access panel.

Disclosed is a novel multi-class interlock. The interlock includes a main lock and a pair of main lock hooks adapted for the main lock. The main lock includes a main lock housing, a control mechanism, and a pair of main lock cylinder assemblies. The main lock cylinder assemblies and the control mechanism both are arranged within the main lock housing. The pair of main lock assemblies are located at both sides of the control mechanism, respectively. The control mechanism is capable of controlling the locking and unlocking of all of the main lock cylinder assemblies. The main lock hooks are provided with a plurality of first protruding teeth adapted for the main lock cylinder assemblies. The present invention provides a multi-class interlock which uses multiple-class interlocking to realize easy closing for the case.

A device for opening/closing an article includes an assembly button and a clasp casing with a mechanism including a housing, locking member and latch; the mechanism structured so with the housing in a first position and the button is inserted into the casing, the locking member immobilizes the button at least with respect to translation, when the housing is made to rotate and passes from its first to a second position, the member is moved until the button is released and the latch is driven with translational movement into the casing until the button is pushed out of the casing and the housing and the member are immobilized, when the button is reinserted into the casing, it pushes the latch which releases the housing, which is rotated and passes from its second to first position and the member is moved until the button is immobilized with respect to translation.
