Abstract: A cam-locking system for use with a retractable driveshaft that includes a housing, a cam carrier located at least partially in the housing, and a cam rotatably coupled to the cam carrier. Translation of the cam carrier along a central axis allows the cam to rotate into cooperative engagement with a catch recess on an interior surface of the housing, preventing the cam carrier from translating backwards, and thereby maintaining the retractable driveshaft in an engaged position. Further advancement of the cam carrier allows that cam to rotate into and unlocking gap in the interior surface of the housing, which enables the cam carrier to translate backwards along the central axis below the locked position, thereby disengaging the retractable driveshaft.

Abstract: A connector is formed from a hollow barrel, an elongate pin and a hook. A pair of parallel channels are formed in one end of the barrel. The pin has an enlarged head and an attached shaft that extends through both the barrel and the base of the hook. The pin and the hook rotate as a unit. Such rotation causes the head of the pin to either block or open the channels. Two parallel strands of a sheet of infill material are received in the channels while open, and the pin rotated until the head blocks the channels, thereby capturing the strands. This rotation concurrently brings a concave portion of the hook into a position aligned with and facing a nearby post. A nut is tightened on the end of the shaft in order to firmly join the connector, sheet and post.

The load pins pass through the alignment guides to releasably engage the load axis apertures to connect the first and second supports together. The release pins permit separation of the first and second supports from an engaged configuration.

Abstract: The present disclosure is directed to a composite component defining a component aperture extending between a first surface and a second surface. The composite component includes an insert having an insert annular wall positioned in the component aperture. The insert annular wall defines an insert aperture therethrough. An insert flange extends radially outwardly from the insert annular wall and contacts the first surface of the composite component. The insert flange includes a diameter about 1.5 times to about 5 times greater than a smallest diameter of the component aperture defined by the composite component.

Abstract: An apparatus provides a latch with a rotary dial and a leaf spring with teeth that extend from a frame into an engaging position. Inward axial movement of the dial causes the dial to deform the leaf spring and the teeth to extend into the engaging position. In the engaging position, the dial supports the teeth and resists forces that might otherwise cause the teeth to unlatch. In the engaging position, a catch in a track on the dial engages a pin of the frame to maintain the engaging position. From the engaging position, a rotation of the dial unseats the catch and allows the dial to move axially outward and the teeth to recede into the frame.
