Abstract
Abstract An improved connector for affixing in removable manner a choke or compensator-like device to the end of a gun barrel. The connector comprises a connector ring which is adapted to be fixedly attached to the end of the barrel and which receives thereover a connector clip which is in turn affixed to the choke or compensator device. The clip and connector ring co-act with one another through a plurality of flat surfaces on the latter so that a simple rotative twist of the choke produces a snapping engagement of clip arms in certain of the ring flats. Removal of the choke is accomplished by rotation thereof so that the clip arms are caused to move out of engagement with the certain ring flats and hence out of engagement with the ring and the barrel to which it is connected.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
178 words
In a coupling means for releasably connecting a first body to a second body by the application of a rotative force on one body with respect to the other comprising a connector ring means adapted for attachment to the first body and which is characterized by a plurality of respective flat areas thereon for first aligning with and then receivably engaging coupler arms which are adapted for attachment to the second boDy. said respective flat areas including guide flats for directing the arms toward engaging flats located adjacent the guide flats, and engaging flats circumferentially aligned with said guide flats for coupling the arms to the connector ring when the arms are moved thereto, and, a retainer clip means fixedly attached to a second body and which is characterized by a plurality of arms integrally connected thereto for selectively engaging first the guide flats of the connector ring means, and then upon relative rotation of the retainer clip means and the arms, the engaging flats, so as to thereby couple the connector ring means to the retainer clip.
Claim 2
Dependent Claim
178 words
In a coupling means for releasably connecting a first body to a second body by the application of a rotative force on one body with respect to the other comprising a connector ring means adapted for attachment to the first body and which is characterized by a plurality of respective flat areas thereon for first aligning with and then receivably engaging coupler arms which are adapted for attachment to the second boDy. said respective flat areas including guide flats for directing the arms toward engaging flats located adjacent the guide flats, and engaging flats circumferentially aligned with said guide flats for coupling the arms to the connector ring when the arms are moved thereto, and, a retainer clip means fixedly attached to a second body and which is characterized by a plurality of arms integrally connected thereto for selectively engaging first the guide flats of the connector ring means, and then upon relative rotation of the retainer clip means and the arms, the engaging flats, so as to thereby couple the connector ring means to the retainer clip.
Claim 3
Dependent Claim
66 words
The coupling means of claim 1 wherein said guide flats are disposed on the surface of the connector ring means and are characterized by an end wall means for limiting movement of the arms, said engaging flats being properly aligned with said end wall means of said guide flats so that the wall means inherently position the arms preparatory to their rotation into the engaging flats.
Claim 4
Dependent Claim
21 words
The coupling means of claim 2 wherein said guide flats and engaging flats are intermittently, alternately positioned about the surface thereof.
Claim 5
Dependent Claim
42 words
The coupling means of claim 3 wherein the flat areas are disposed in cooperating opposing pairs with the guide flats located opposite one another about the coupling means surface and the engaging flats located opposite one another about the coupling means surface.
Claim 6
Dependent Claim
37 words
The coupling means of claim 4 wherein retainer clip arms extend flexibly from a common base and are so formed in their normal unstressed position as to slidingly engage at least a pair of said guide flats.
Claim 7
Dependent Claim
88 words
The coupling means of claim 5 wherein opposing surface areas on the connector ring which are intermediate the flat areas are farther from one another than are opposing flat areas so that rotative movement of said retainer clip produces distended flexing of the arms over said opposing surface areas, the relative distance of said opposing engaging flats from one another being substantially the same as said opposing guide flats from one another so that the arms are in a normal unstressed state when locked in the engaging flats.
