Abstract: A roof hatch including a vibration resistant latch design that can accommodate stresses applied to the roof hatch during hurricane conditions. The roof hatch can comprise a latch assembly including a biasing portion, a linkage member and a latch portion. The biasing portion can include a first latch incorporating a spring returned handle. The latch portion can include a single point, rotatable slam latch that engages an engagable locking member adapted to prevent spring driven rotary arms from disengaging from the engagable locking member. The linkage member includes a projecting end that is designed to provide a delay between actuation of the biasing portion and engagement of the latch portion. Using the vibration resistant latch design, engagable locking member and the rotatable slam latch, the roof hatch is rated to withstand internal and external pressure of 100 pounds per square foot with a design safety factor up to 200 pounds per square foot.

Abstract translation: 屋顶舱口包括一个可防止飓风条件下施加在屋顶舱口上的应力的抗震闩锁设计。 顶盖可以包括一个闩锁组件，该组件包括一个偏压部分，一个连杆部件和一个闩锁部分。 偏置部分可以包括结合弹簧返回手柄的第一闩锁。 闩锁部分可以包括单点可旋转的闩锁，其接合适于防止弹簧驱动的旋转臂与可接合的锁定构件分离的可接合的锁定构件。 连杆构件包括突出端，突出端被设计成在施力部分的推动和闩锁部分的接合之间提供延迟。 使用防震闩锁设计，可接合的锁定构件和可旋转的闩锁，屋顶舱口额定承受100磅/平方英尺的内部和外部压力，设计安全系数高达每平方英尺200磅。

Abstract: A smoke vent including a curb and door assembly utilizing a continuous hinge assembly that extends an entire length of a door. Hinge members of the door assembly and curb define continuous, extruded hinge members such that the door is supported across the entire length of the hinge members, whereby localized deflection of the curb is avoided. By supporting the door across the entire length of the hinge member, a door seal can be evenly compressed against the curb so as to prevent moisture/water intrusion when the door is in a closed disposition. The door assembly can further include a dome member that substantially defines an upper and lower surface of the door(s). Each door can comprise a plurality of retainer clips that positively couple the dome member to extruded members that define a door frame while providing a moisture resistant seal between the dome member and the door frame.
