Fenestration systems and associated methods include use of a lock assembly having a housing, a cam gear, a reversal gear, and one or more catches. Various aspects relate to enhanced locking/security, including repeatability and overall efficacy.

In an example, a retainer may include a first latch, a plunger, a second latch, and a linkage engaging the second latch with the first latch. The plunger may actuate the first latch, and the linkage may actuate the second latch upon the first latch being actuated.

A modular latch system has an activation module comprising an activation rod, a latch module comprising a biased latch, and a control cable connecting the activation module to the latch module so that rotation of the activation rod can retract the latch.

A structure, for example a vehicle roof, may define an opening receiving one or more removable panels. The removable panels may each include a panel body configured to cover the opening, and a plurality of latches. The latches may each be positioned adjacent a respective edge of the body and configured to translate between different positions. The removable panel may also include an actuator and a plurality of latch links, with each latch link having a first end connected to a corresponding one of the latches, and each latch link having a second end operably linked with the actuator. Rotation of the actuator may drive each of the latches from an open position of the latch to a closed position, while rotation of the actuator in an opposite direction may drive each of the latches from the closed position of the latch to the open position of the latch.

A safety cabinet includes an enclosure and at least one door to selectively seal the enclosure. The safety cabinet can be used to store, for example, flammable liquids, flammable waste, corrosives, pesticides, or combustible waste. The safety cabinet incorporates a thermally-actuated damper that includes a body, a valve plate, and a pivot assembly. The valve plate is disposed within the passage of the body such that the valve plate is movable between an open position and a closed position. The pivot assembly includes a biasing system adapted to bias the valve plate to the closed position and a fusible link interconnected between the body and the biasing system to constrain the valve plate from moving from the open position to the closed position. The fusible link is configured to melt at a predetermined temperature to thereby allow the biasing system to move the valve plate to the closed position.

A latching assembly for use on a pick-up truck, and particularly on a truck bed cover configured to sit over a truck bed section is provided. The latching assembly includes an electronic release assembly and a mechanical override system. An electronic release assembly includes a first rod coupled to a first electronic actuator and a second rod coupled to a second electronic actuator. The electronic release assembly also includes a first electronic actuator that selectively moves the first latch catch and the second electronic actuator that selectively moves the second latch catch. A switch is engaged to send a signal to the first and second electronic actuators to cause the first and second latch catches to disengage from the truck bed section. The first and second rods and the first and second electronic actuators also serve as part of a mechanical override system that selectively unlatches at least a portion of the truck bed cover from the truck bed section. The mechanical override system moves the first and second rods to mechanically cause the first and second electronic actuators, respectively, to manually move the first and second latch catches, respectively, to unlatch the at least the portion of the truck bed cover from the truck bed section as an alternative to moving the first and second latch catches by electrically moving the first and second electronic actuators.

The present invention relates to a transportation device of a withdrawable circuit breaker, and more particularly, to a transportation device of a withdrawable circuit breaker capable of simultaneously moving right and left handles of a girder assembly for restricting movement of the transportation device or releasing a restricted state. The transportation device of a circuit breaker includes: a truck assembly on which a body of the circuit breaker is loadable; a body plate of a girder assembly installed on a front surface of the truck assembly; a pair of sliding plates slidably installed in the body plate; and a rotation plate having both sides to which leg portions of the sliding plates are rotatably coupled, respectively, wherein the rotation plate is inserted into a lead screw penetratingly-formed at a central part of the girder assembly.

The present invention discloses a novel pet cage door, including a door frame and a switch door capable of rotating relative to the door frame so as to be opened and closed. A locking apparatus is disposed between the switch door and the door frame, and the locking apparatus includes a housing disposed on the switch door. The present invention has a simple structure and requires low costs.

A fenestration assembly includes a frame assembly, a movable sash assembly and a lock assembly. The lock assembly includes a first lock and a second side lock. The first lock operatively locks and unlocks the moveable sash to the frame assembly in a first direction only when the movable sash is in a fully closed position. The first side lock operatively locks and unlocks the movable sash in a second direction perpendicular to the first direction both when the movable sash is in the fully closed position and a partially open position.
