Abstract: A latch for a thrust reverser duct on an aircraft engine. The latch accomplishes work during both the closing stroke and the handle folding stroke. An outer handle 100 release trigger 112 can lock an outer handle 100 to an inner handle 60 to fix the relative position of the outer handle 100, the inner handle 60, an idler link 80, a rocker link 78 and a secondary link 75. While they are in fixed position, the parts act as a closing handle unit 125 during the closing stroke. Once the closing stroke is completed, the inner handle 60 is locked into a fixed position with hook arm 40 and a primary link 70. The outer handler release trigger 112 can then be disengaged and the secondary link 75, the rocker link 78 and the idler link 80 work to provide mechanical advantage during the folding of the outer handle 100.

Abstract: A safety device for an adjustable bed having an articulated mattress is shown including a power drive module having adjustable sections that support corresponding sections of the articulated mattress. Multiple winding electrical motors are mounted within the drive module for driving the adjustable sections through linkages. Due to the weight of the articulated mattress and adjustable section, the linkages are always in tension. However, should a foreign object, such as a hand, be placed below the mattress supporting section as it is lowered, the linkage will be exposed to a compression force. A switch is mounted within the linkage to sense the compression force and inhibit the motor winding which lowers the bed. However, the winding which raises the adjustable bed continues to be enabled to permit the bed to be raised and the foreign object removed.
