Abstract
Abstract The invention relates to a connector for detachable connection to an article to enable a cord, chain or the like to be attached to the article. There is disclosed a connector attached to a ball to provide a captive ball for playing games. The connector has a generally elongated body portion and is split longitudinally into two halves from one end to a position part the way along the connector. The one end is enlarged with respect to the body portion immediately adjacent thereto and a screw is adapted to cause expansion of the enlarged head in a direction transverse to the longitudinal axis of the connector when the head of the screw is pulled between the two halves by a cylindrical nut arranged on the screw in a cut-out in the body. The cut-out prevents longitudinal movement of the nut. Expansion of the end enables it to be retained in any suitable cavity accessible through a restricted neck portion. The other end of the connector has an enclosed loop for receiving a cord, chain or the like. The connector may be used to attach pendant jewelry to a neck chain or hang ornaments from a ceiling or other structure as well as for many other purposes. A further form of the connector having a cylindrical body for insertion into an article is also disclosed.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
183 words
A connector having a generally elongated body portion which is split in a longitudinal direction from one end to a position part the way along its length so as to form two side members which are joined at said position and which may be resiliently separated at said one end, said connector having a part at or adjacent said one end which is of greater cross-sectional dimension than the cross-sectional dimension of the connector at least adjacent said part and in a direction towards said position, manually operable screw means on said connector and operable to force said two members away from each other causing said part to expand in a direction transverse to said longitudinal direction, said connector being held, by said part, in detachable connection with an article having a cavity therein accessible via a restricted neck portion in a manner wherein said connector is rotatable about the longitudinal axis thereof and at least partly pivotal in any direction relative to said article, and said connector having means adjacent the other end thereof for retaining a cord, chain, or the like.
Claim 2
Dependent Claim
183 words
A connector having a generally elongated body portion which is split in a longitudinal direction from one end to a position part the way along its length so as to form two side members which are joined at said position and which may be resiliently separated at said one end, said connector having a part at or adjacent said one end which is of greater cross-sectional dimension than the cross-sectional dimension of the connector at least adjacent said part and in a direction towards said position, manually operable screw means on said connector and operable to force said two members away from each other causing said part to expand in a direction transverse to said longitudinal direction, said connector being held, by said part, in detachable connection with an article having a cavity therein accessible via a restricted neck portion in a manner wherein said connector is rotatable about the longitudinal axis thereof and at least partly pivotal in any direction relative to said article, and said connector having means adjacent the other end thereof for retaining a cord, chain, or the like.
Claim 3
Dependent Claim
84 words
A connector as defined in claim 1 wherein said screw means comprises a screw non-rotatably arranged along the longitudinal axis of said connector between said members and having a head arranged at said one end and adapted to move between the free ends of said members when said screw is caused to move longitudinally, and a nut rotatably arranged on said screw, means on said body portion to hold said nut against longitudinal movement such that rotation thereof causes said screw to move longitudinally.
Claim 4
Dependent Claim
65 words
A connector as defined in claim 1 wherein said article is a ball which is adapted for attachment to said connector for providing a captive ball for playing a ball game, said cavity being an inwardly extending cavity at the outer surface of said ball and said neck portion being of reduced cross-section compared with said cavity and being at or adjacent said outer surface.
Claim 5
Dependent Claim
87 words
A ball and connector arrangement as defined in claim 3 wherein said screw means comprises a screw non-rotatably arranged along the longitudinal axis of said connector between said members and having a head arranged at said one end and adapted to move between the free ends of said members when said screw is caused to move longitudinally and a nut rotatably arranged on said screw, means on said body portion to hold said nut against longitudinal movement such that rotation thereof causes said screw to move longitudinally.
Claim 6
Dependent Claim
58 words
A ball and connector as defined in claim 4 wherein said head is tapered to facilitate movement between said free ends of said members, said ball is an inflatable ball and said cavity provides access to a passageway for inflating said ball, said passageway having a valve or stopper therein to prevent air in said ball from escaping.
Claim 7
Dependent Claim
34 words
A ball and connector arrangement as defined in claim 5 wherein said cavity and said passageway are formed in an inwardly extending protrusion within said ball, said protrusion being moulded inegral with said ball.
Claim 8
Dependent Claim
67 words
A connector as defined in claim 2 wherein said nut is a cylindrical nut and said means to hold said nut against longitudinal movement comprises a cut-out in said body portion, which cut-out serves to prevent any substantial movement of said nut in a longitudinal direction, and said means adjacent the other end of said body portion comprises an enclosed loop formed integral with said body portion.
Claim 9
Dependent Claim
68 words
A ball and connector as defined in claim 4 wherein said ball is an inflatable ball and said cavity is provided in an insert adapted to extend through the casing of the ball from inside to outside, said insert being generally cylindrical and having a flange on the inside end to hold said insert within the ball, said cavity being arranged in the outermost end of the insert.
Claim 10
Dependent Claim
44 words
A ball and connector as defined in claim 8 wherein said ball is a leather ball, said insert being inserted through said casing at a seam of the ball, and a large washer being provided between said flange and the inside of said casing.
Claim 11
Dependent Claim
37 words
A connector as defined in claim 2 wherein said article is ornamental jewelry and said means adjacent the other end thereof is an enclosed loop for receiving a neck chain or the like for supporting said jewelry.
