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.).

A door closer, including: an anchor assembly, including: a frame mounting plate which is fixable relative to a door frame; and an adjustor plate; and an actuator assembly for mounting within the thickness of a door leaf to move the door leaf between open and closed configurations relative to the door frame, the actuator assembly including an operating member coupled by a link to the adjustor plate and mounted for a range of movements between a fully retracted position, in which the anchor assembly is held adjacent the actuator assembly when the door leaf is in the closed configuration, and an extended position, in which the anchor assembly is in spaced relation to the actuator assembly when the door leaf is in the open configuration, the link being configured to extend from the adjustor plate along a first axis, wherein the frame mounting plate is provided with one or more slot(s), the or each slot being elongated along a second axis, the second axis being generally orthogonal to the first axis.

Described is a louver having a frame that forms an enclosure defining an opening, and a plurality of louver blades disposed within the opening. Each of the plurality of louver blades include a catch member that longitudinally extends between a first blade end and a second blade end of a corresponding louver blade. The louver may also include a rotation assembly configured to rotatably couple with the plurality of louver blades and the frame. The plurality of louver blades may autonomously rotate about rotation members of the rotation assembly based on environmental elements captured in the catch member such that the plurality of louver blades are configured in an open position in response to no water in the catch member and are configured in a closed position in response to an amount of environmental elements in the catch member.

The subject matter of the invention are various methods, systems and devices and the ways of their installation/fitting/assembly of emergency opening of manholes (entry openings) or loading holes (door) in emergency situations, especially an emergency move/shift of movable components closing manholes (entry openings), exit openings, loading or unloading openings, from closed position into opened position, such as doors, manholes, hatches, gates, emergency exits, windows, window panes and other, especially in means of transport, construction furnishing devices and premises (buildings). The invention is connected with the use of pyrotechnic actuators which can be telescopic actuators, piston actuators or flexible ones, driven with propelling actuating agents which are in the form of gas generators, pressure of compressed gas or air, compressed air from a compressor or a material with shape memory.
