Examples described herein include latch mechanisms for covers. In some examples, an electronic device has an enclosure, a cover, and a latch mechanism. The enclosure may include an opening. The latch mechanism may include a rotatable arm, a spring to bias the rotatable arm to secure the cover to the enclosure, and a cam moveable between a rest position and an engaged position. In the engaged position, the cam moves the rotatable arm to release the cover.

A compression latch assembly for latching a panel to a frame includes a housing assembly, a lockplug assembly, a handle actuator assembly, and a rotating pawl assembly. The housing assembly defines an exterior well and a first and second compartment. The lockplug assembly resides within the first compartment and includes a lockplug having a circumferential guide surface. The handle actuator assembly has a handle within the exterior well, a crank coupled to the handle, and a drive shaft coupled to the crank. The handle and the crank rotate about common pivot point within the second compartment. The handle is selectively captured and ejected by interaction between the circumferential guide surface and a locking pin on the handle. The rotating pawl assembly has a hook defining a slot that receives the drive shaft. Pivotal movement of the handle actuates the hook by movement of the drive shaft within the slot.

The invention relates to a lock (1) which can be actively released and locked by control technology, particularly for use in automatic storage machines having a plurality of compartments with compartment doors (2) which are to be opened individually, and to an automatic storage machine having at least one such lock (1). The lock (1) comprises a detent pawl (14), which can lock a locking element (9), which is permanently connected to a compartment door (2), in the lock such that the compartment door (2) can be held in closed position. The lock further has a first electric drive element (17) which transitions the detent pawl (14) from the locking position to a release position upon the applying of electrical power, such that the compartment door (2) can be opened. The lock (1) further comprises a security device (32), which prevents an automatic reset of the detent pawl (14) from the release position to the locking position when the lock (1) is in an unpowered state or the automatic storage machine is in an unpowered state, and an unintentional, accidental or improper locking of a compartment door can thus be avoided. In order to properly lock a compartment door, the security device (32) of the lock (1) comprises a second electric drive element, by means of which the detent pawl (14) can be transitioned back to the locking position thereof upon the applying of electrical power to said second electric drive element during closing of the compartment door (2).

An animal enclosure including a plurality of members defining an interior of the enclosure. One of the plurality of members includes a first member having a frame structure and door assembly formed by a plurality of interconnected horizontal and vertical wires. At least two of the horizontal wires of the frame structure form a hook positioned inside the defined opening. The door assembly is coupled to the frame and moves between open and closed positions. The door assembly includes a first door and a second door removably coupled to one another. The enclosure also includes a latch assembly for releasing the door assembly from the frame structure. In the closed position, at least one horizontal wire of the first door and at least one horizontal wire of the second door are coupled to the hooks formed by the at least two horizontal wires of the frame structure.

A door locking device for hydro excavation equipment. The door locking device includes a grapple support housing secured to a door of a debris tank, a lower gripping jaw having a lower pin defining a lower axis about which the lower gripping jaw is configured to rotate, and an upper gripping jaw having an upper pin defining an upper axis about which the upper gripping jaw is configured to rotate. The locking device also includes a yoke having a first end coupled to proximate ends of the lower and upper gripping jaw, and an actuator coupled to a second end of the yoke and configured to extend and retract the yoke to cause the lower and upper gripping jaws to rotate in response thereto about the lower axis and the upper axis, respectively.

A door-equipped housing includes a box body having an opening formed on one side thereof, and a door to close the opening, the door being supported by the box body to be rotatable about a rotational axis. The box body has a projecting portion formed on an inside of a wall of the box body extending from the opening toward a deep side of the box body. The door includes a hook portion to engage the projected portion for preventing the door from opening, the hook portion being located on a deeper side of the box body than the projecting portion as the door closes the opening, and a flexible part extending in a direction away from a surface of the wall having the projected portion formed thereon as the door closes the opening. The flexible part bends together with a movement of the hook portion to climb over the projecting portion during an opening/closing operation of the door.
