摘要： A hold down device is provided using a drive knob having a clutch therein which turns a drive shaft for moving a pawl shaft in and out with respect to the drive shaft. A pawl on the end of the pawl shaft is provided with a cam-like surface which engages a cam-like aperture in a pawl receptacle. The pawl shaft has a cam follower which rides within a cam surface in a cam bracket that surrounds the shaft. Under the urging of a spring, the position of the pawl is controlled from its fully extended, unlocked position to a pre-capture position where the pawl is oriented at approximately 45.degree. to an aperture within the pawl receptacle. Insertion of the pawl into the pawl receptacle forces the pawl to rotate an additional 45.degree. against the urging of the spring. After full insertion of the pawl into the receptacle, the pawl rotates back to its 45.degree. position where it is captured therein. Further tightening of the knob will move the pawl to a locked, preload position under the control of the cam surface within the cam bracket.
摘要翻译：使用具有其中的离合器的驱动旋钮来提供压紧装置，其中转动用于使棘爪轴相对于驱动轴移入和移出的驱动轴。在棘爪轴的端部上的棘爪设置有凸轮状表面，其接合棘爪容器中的凸轮状孔。棘爪轴具有凸轮从动件，该凸轮从动件在围绕轴的凸轮支架内的凸轮表面内骑行。在弹簧的推动下，棘爪的位置从其完全延伸的解锁位置被控制到预捕获位置，其中爪被定位在棘爪容器内的大致45度处。棘爪插入棘爪接收器中迫使棘爪相对于弹簧的推动另外旋转45度。在将爪完全插入到容器中之后，棘爪回到其被捕获在其中的45°位置。在凸轮支架内的凸轮表面的控制下，进一步拧紧旋钮将使棘爪移动到锁定的预加载位置。

摘要： A toggle latch is shown which retains a structure, such as an aircraft door, latched against a second structure, such as the fuselage. The latch includes a housing having a latch actuator joined to the housing a first pivot point and a latch member joined to the housing at a second pivot point. A linkage joins the latch actuator and latch member at third and fourth pivot points. In the latched position, the fourth pivot point is positioned past a center line between the first and third pivot points to create the over-center, toggle effect of the latch. A safety catch is pivoted within the latch actuator which extends into a passage in the actuator. The safety catch also engages the housing when the toggle latch is in its latched position to lock the latch closed. Insertion of a tool into the passage engages the safety catch to remove it from its locking contact with the housing and free the latch actuator for opening the latch.
摘要翻译：示出了一个掣子闩锁，其保持诸如飞机门的结构，其抵靠第二结构（诸如机身）锁定。闩锁包括具有连接到壳体的闩锁致动器的壳体，第一枢转点和在第二枢转点处连接到壳体的闩锁构件。连杆在第三和第四枢转点处连接闩锁致动器和闩锁构件。在锁定位置，第四枢转点定位成超过第一和第三枢转点之间的中心线，以产生闩锁的过中心的拨动效果。在闩锁致动器内枢转安全锁扣，该闩锁致动器延伸到致动器中的通道中。当掣子闩锁处于其锁定位置以锁定闩锁关闭时，安全锁扣还与壳体接合。将工具插入通道中接合安全锁扣以从其与壳体的锁定接触中移除，并释放闩锁致动器以打开闩锁。

摘要： A low-profile, over-center tension latch assembly is provided which has a handle (20) which opens fully for inspection or adjustment of the assembly while under load, and which may be indexed into a position with a link mechanism (70) in order to act therewith for releasing a keeper engaging member (50) from engagement with a keeper assembly. The handle (70) is locked in a closed position in a manner which secures it to the link mechanism (70) while trapping the keeper engaging member (50) therebetween. The arrangement of the handle (20), keeper engaging member (50) and link mechanism (70) is such as to allow the assembly to be aerodynamically flush mounted with the surface of the structure in which it is installed. Both the handle (20) and the keeper engaging member (50) are pivotally mounted at an end of the link mechanism which is opposite that end which mounts the link mechanism to the aircraft structure. The keeper engaging member (50) extends over the top of the mounting bushing (74) for a resulting over-center latch which operates within a low-profile envelope.
摘要翻译：提供了一种薄型的超中心张力闩锁组件，其具有手柄（20），该手柄（20）在负载下完全打开以用于组件的检查或调整，并且其可以被索引到具有连杆机构（70）的位置以便与其一起作用以释放保持器接合构件（50）与保持器组件的接合。手柄（70）以将其固定到连杆机构（70）的方式锁定在关闭位置，同时将保持器接合构件（50）夹在其间。手柄（20），保持器接合构件（50）和连杆机构（70）的布置使得组件能够与其安装在其中的结构的表面空气动力学地齐平地安装。手柄（20）和保持器接合构件（50）都可枢转地安装在连杆机构的与将连杆机构安装到飞机结构的端部相对的端部处。保持器接合构件（50）在安装衬套（74）的顶部上延伸，用于产生的超中心闩锁，其在低调范围内工作。
