Abstract:

A quick release bolt system utilizes two bolt sections. Each bolt section approximates one half of a bolt and has a half head portion and half threaded portion. Each section has an inner face which are parallel to and approach one another when the two bolt sections are assembled. A slide insert is receivable between the bolt section faces such that when the sections are assembled with the slide insert therebetween, the bolt can be threaded into a threaded receiving aperture in a block or the like with the threads of the bolt engaging the corresponding threads of the aperture. On the other hand, with the slide insert removed, the bolt sections approach each other and abut at their flat faces sufficiently close such that the two bolt sections can be slid into the threaded receiving aperture without the threads of the bolt sections engaging the threads of the threaded aperture. When the bolt is in position, the insert is slid between the bolt sections causing the sections to move away from one another and align so as to cause engagement between the threads of the aperture and the threads of the half sections. The bolt can then be tightened down.
