An electronic chassis includes a motherboard sled configured to engage in or out of the electronic chassis. The motherboard sled includes a housing and a mechanical actuator for engaging the motherboard sled into or out of an electronic chassis. The mechanical actuator includes at least one lever rotatably coupled to a hinge to form a first fulcrum adjacent to a vertical edge of a front surface of the housing. The mechanical actuator also includes a guiding arm adjacent to the hinge and mechanically connected to the at least one lever to form a second fulcrum. The guiding arm rotates between a secured position adjacent to the front surface and an unsecured position away from the front surface.

A gate-latching assembly is configured for utilization with a gate assembly. The gate assembly includes a stationary gate post configured to be mounted to, and to extend from, a working surface once the stationary gate post is mounted to the working surface, and in which the gate assembly also includes a movable gate door configured to be movable relative to the stationary gate post. There is provided a combination for utilization with the gate assembly. The combination includes any one of (A) a striker base assembly and a striker member, (B) a latch base assembly and a latch assembly, and/or (C) a striker base assembly, a striker member, a latch base assembly and a latch assembly.

A latch arrangement may comprise a latch bolt configured to rotate about a pivot, and a shear pin coupled to the latch bolt. A counterbore may receive the shear pin whereby lateral loads may be transferred between a door panel and a frame.

This application is directed to systems and methods of locking and unlocking a hatch lid or any other type of opening having a hinged covering. In some embodiments, a blade is actuated by a motor or linear actuator. Blades of the inventive subject matter can include one or two racks that interact with one or two pinion gears. In embodiments having rotational motors, a pinion gear can be coupled with that motor and with a rack that can cause the blade to move when the motor turns. In embodiments having linear actuators, the linear actuator more directly causes the blade to move. Other embodiments of the inventive subject matter include a screw mechanism that can interact with a locker receptacle upon rotating a motor coupled thereto.

The inventive subject matter of this application is directed to system and methods that bring about the opening and closing of hatches, doors, windows, or other hinged openings. Embodiments of the inventive subject matter feature one or more levers that are coupled with a motor or linear actuator. Upon activating a motor or linear actuator, a lever coupled thereto (e.g., by a linkage) rotates, taking the system from a locked configuration to an unlocked configurations. In some embodiments, continued actuation brings the system from a closed configuration to an open configuration.

Systems and methods described in this application are directed to hatch lid actuation systems. Actuation systems of the inventive subject matter are configured to effect the opening and closing of lids that are hingedly coupled with an opening. An embodiment featuring a rotational actuator, e.g., a motor, as well as an embodiment featuring a linear actuator are described. Embodiments having rotational actuators can additionally feature a gearbox. Embodiments of the inventive subject matter can also include sensor packages that can determine various hatch lid conditions (e.g., whether a lid is open, closed, wet, etc.).
