Abstract
A quick release bolt for securing two or more parts together is disclosed. The quick-release bolt includes a threaded end and a slotted end opposite the threaded end. The slotted end includes a slot extending across a diameter of the bolt and extending axially into the bolt. A release/lock plate is pivotally attached to the bolt within the slot in the bolt by a pin that is attached to the bolt. The pin extends transversely through the slot in the bolt and passes through a slot in the release/lock plate. The release/lock plate may be pivoted between locking and releasing positions when the bolt is loosened only about one-half to one-quarter of a turn from a tightened position.
