摘要： A mechanism of the hold-down type is provided which permits a predetermined load to be applied to a unit, e.g. an avionics box, secured upon a structure, while also permitting insertion and extraction of that unit through operation of the mechanism. The mechanism is particularly adapted for use in relatively confined areas. It includes a hook (70) which is mounted to the unit itself, and a housing (20) which is constructed for releaseable engagement with the hook (70) and which houses the clutching mechanism components (28, 30, 38, 42, 43, 45). A drive shaft portion (31) extends from one end only of the housing (20) and is retained by a hinge-type mounting which includes a bracket member (50) secured to the structure supporting the unit, and a nut element (51). The nut element (51) and bracket member (50) are constructed so as to limit both the downward and upward pivotal movement of the housing (20) and the drive shaft (30).

摘要： Disclosed is an increased strength dogging mechanism operable by a handle for releasably securing a door on each side of the door to a structure. The dogging mechanism includes a plurality of dog keepers each having a ramp portion and a seating portion mounted to each side of the door. A dog having a roller is rotatably mounted to engage a cooperatively associated dog keeper. A mounting bolt extends through the structure and through the approximate center of each dog. A drive assembly which is movable by the handle between open and closed positions moves each dog, simultaneously, between unlocked and locked positions. As the dog is rotated to the locked position, the roller of each dog engages the ramp portion of its associated dog keeper and rolls upon the ramp and into the seating portion. The action of the dogs rolling upon the ramps of the dog keepers on each side of the door moves the door perpendicularly into the structure compressing a seal and rigidly secures the door on all sides to the structure to form a waterproof enclosure.
摘要翻译：公开了一种增强的强度锁定机构，其通过手柄可操作，用于将门的每一侧可释放地固定到结构上。锁定机构包括多个狗保持器，每个狗保持器具有安装在门的每一侧的斜坡部分和就座部分。具有滚子的狗被可旋转地安装以接合协作关联的狗保持器。安装螺栓延伸穿过结构并穿过每只狗的大致中心。在打开和关闭位置之间可由手柄移动的驱动组件在同时处于解锁位置和锁定位置之间的同时移动每个狗。当狗旋转到锁定位置时，每个狗的滚子接合其相关联的狗保持器的斜坡部分并在斜坡上滚动并进入就座部分。在门的每一侧的狗保持器的坡道上滚动的狗的动作将门垂直移动到压缩密封件的结构中，并将门的所有侧面刚性地固定到结构上以形成防水外壳。

摘要： A hold-down device is shown for connecting a chassis to a rack under a predetermined force and for extracting the chassis from the rack. The device includes a threaded bolt which receives a tubular, internally threaded clutch drive shaft having an integral clutch plate. A clutch drive disc slides over the shaft to engage the clutch plate, while a ratchet cam slides over the clutch drive disc. The ratchet cam has a set of ratchet teeth that engage similar teeth on the hook connector that slides over the shaft from the opposite side of the clutch plate. Belleville spring washers urge the clutch plate and clutch drive disc into engagement, while other springs urge the ratchet teeth apart. A knob fits over the springs and slides over the shaft and an extractor slides over the shaft from the opposite direction to complete the device.
