Quick-release fastener with intermittent threads
First Claim
1. A quick-release fastener comprising a threaded stud and a complementarily threaded receptacle, said stud and said receptacle each having at least one longitudinally extending threaded portion and at least one longitudinally extending unthreaded portion, said at least one threaded portion of said stud and said receptacle respectively having a lesser angular width than said at least one unthreaded portion of said receptacle and said stud respectively, said fastener including at least one longitudinal rib which runs along the length of said at least one threaded portion, whereby said stud can be inserted into said receptacle with said threaded and unthreaded portions of said stud and receptacle respectively aligned and can thereafter be rotated to engage said respective threaded portions, said stop preventing over rotation of said stud within said receptacle thereby to define a fastened orientation of said stud within said receptacle.

Abstract
A quick-release fastener comprises a threaded stud (11) and a complementarily threaded receptacle (1), the stud and receptacle each having one or more longitudinally extending threaded and unthreaded portions (15,8). The or each threaded portion (15,8) of the stud (11) and receptacle (1) respectively has a lesser angular width than the unthreaded portions of the receptacle and stud respectively. The fastener has at least one stop (9) at one edge of the or one of the threaded portions (8,15) on the stud or receptacle, whereby the stud can be inserted into the receptacle with the threaded (8,15) and unthreaded portions of the stud (11) and receptacle (1) respectively aligned and can thereafter be rotated to engage the respective threaded portions. The stop (9) prevents over-rotation of the stud (11) within the receptacle (1) thereby to define a fastened orientation of the stud within the receptacle.
