Abstract
Abstract A coupling ring is slideably received onto a cylindrical plug shell that is mateable with a receptacle. A removable end piece in the coupling ring end has an internal set of key ways which correspond to a complementary set of keys on the receptacle. The end piece has shallow recesses on its outer surface which align with passageways extending through the coupling ring. Each passageway has a metal ball of such diameter as to have parts thereof extending inwardly of the opening and into the end piece recesses. A locking ring is slidingly received over the outer end of the coupling ring and includes a first portion which contactingly engages each of the metal balls holding them in an inwardly extending relation into the recesses on the outer surface of the releasable portion (locked mode). The locking ring is movable to a second position in which an inner groove is aligned with each of the passageways extending through the coupling ring so as to release pressure on the metal balls (released mode).

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
227 words
A rapidly releasable connector having a receptacle receivable within a plug shell, and a hollow coupling ring rotatably received on the plug shell for moving the plug shell and receptacle toward and away from each other depending upon the direction of rotation, comprising: said coupling ring having at least one opening extending radially therethrough at a point spaced inwardly from the outer end; ringlike means slidingly received onto the outer end portion of the coupling ring and movable from a first position presenting a surface covering the coupling ring opening to a second position locating a recess or the ringlike means directly opposite said openings; separable end piece means fitted within the open end of the coupling ring and having a recess on an outer surface located directly opposite the opening in the coupling ring, said separable end piece means including a radially inwardly directed flange for engaging the receptacle during mating of the plug shell and receptacle; and a ball located within the coupling ring opening and having parts thereof lockingly extending into the separable end piece means when the ringlike means inner surface is located directly opposite the coupling ring opening, which ball is free to move entirely into the coupling ring opening when the ringlike means recess is directly opposite the coupling ring opening releasing the separable end piece means from the coupling ring.
Claim 2
Dependent Claim
227 words
A rapidly releasable connector having a receptacle receivable within a plug shell, and a hollow coupling ring rotatably received on the plug shell for moving the plug shell and receptacle toward and away from each other depending upon the direction of rotation, comprising: said coupling ring having at least one opening extending radially therethrough at a point spaced inwardly from the outer end; ringlike means slidingly received onto the outer end portion of the coupling ring and movable from a first position presenting a surface covering the coupling ring opening to a second position locating a recess or the ringlike means directly opposite said openings; separable end piece means fitted within the open end of the coupling ring and having a recess on an outer surface located directly opposite the opening in the coupling ring, said separable end piece means including a radially inwardly directed flange for engaging the receptacle during mating of the plug shell and receptacle; and a ball located within the coupling ring opening and having parts thereof lockingly extending into the separable end piece means when the ringlike means inner surface is located directly opposite the coupling ring opening, which ball is free to move entirely into the coupling ring opening when the ringlike means recess is directly opposite the coupling ring opening releasing the separable end piece means from the coupling ring.
Claim 3
Dependent Claim
49 words
A rapidly releasable connector as in claim 1, in which the coupling ring includes three angularly spaced openings within each of which is received a separate ball, and the separable end piece means outer surface includes three angularly spaced recesses which are individually aligned with respective coupling ring openings.
Claim 4
Dependent Claim
49 words
A rapidly releasable connector as in claim 1, in which the coupling ring includes three angularly spaced openings within each of which is received a separate ball, and the separable end piece means outer surface includes three angularly spaced recesses which are individually aligned with respective coupling ring openings.
Claim 5
Dependent Claim
64 words
A rapidly releasable connector as in claim 1, in which the coupling ring opening is tapered having a diameter measured at the inner surface of the coupling ring which is less than the opening diameter at the coupling ring outer surface, said ball having a diameter less than the greater coupling ring opening diameter and greater than that of the less coupling opening diamter.
Claim 6
Dependent Claim
64 words
A rapidly releasable connector as in claim 1, in which the coupling ring opening is tapered having a diameter measured at the inner surface of the coupling ring which is less than the opening diameter at the coupling ring outer surface, said ball having a diameter less than the greater coupling ring opening diameter and greater than that of the lesser coupling opening diameter.
Claim 7
Dependent Claim
49 words
A rapidly releasable connector as in claim 5, in which the coupling ring includes three angularly spaced openings within each of which is receved a separate ball, and the separable end piece means outer surface includes three angularly spaced recesses which are individually aligned with respective coupling ring openings.
