Abstract
Abstract The disclosure relates to a connector joint that consists of separable elements that may be either locked in axial alignment or permitted to pivot relative to each other. The preferred embodiment disclosed utilizes a tubular receiving sleeve with a radius flared socket as one element and tubular pin carrying housing having a partially spherical head of a size corresponding to that of the sleeve.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
339 words
A hollowed connector joint for the rigid interconnection of a plurality of pole sections of the bungee cord variety wherein the hollow within said connector joint has a selected axial allignment common to the elemental pieces thereof when said pole sections are rigidly interconnected in a selected orientation of interconnected pole sections, and wherein a flexible resilient cord member of substantially uniform cross section is attached at opposite ends of the pole section assembly, said cord is normally under tension and said cord is threaded through said pole sections and through said hollowed connector joint, comprising: a two piece connector joint assembly wherein first and second pieces are adapted for separation and for mating relation, and wherein the hollow within said first and second pieces of said connector joint assembly has a substantially uniform cross section, and; a rigid tubular member disposed within the hollow of said connector joint assembly with said flexible cord member threaded therethrough; said tubular member having a respective hollow configuration of uniform cross section compatible with said uniform cross section of said cord member and larger in dimensions with respect thereto such that said cord member is free to move within said tubular member; said tubular member having an outer configuration compatible with the configuration of the cross section of the hollow within said connector joint assembly and smaller in dimensions with respect thereto such that said tubular member is moveable in contiguous relation within the hollow of said connector joint assembly when said pole sections are selectively oriented with respect each other such that the hollows in each of said first and second pieces of said joint assembly are in axial alignment; said tubular member including restraint means adapted to limit the travel of said tubular member within said hollow of said connector joint assembly such that in a first position said tubular member is completely contained within one piece of said joint assembly and in a second position said tubular member is within both of said pieces of said connector joint assembly.
Claim 2
Dependent Claim
339 words
A hollowed connector joint for the rigid interconnection of a plurality of pole sections of the bungee cord variety wherein the hollow within said connector joint has a selected axial allignment common to the elemental pieces thereof when said pole sections are rigidly interconnected in a selected orientation of interconnected pole sections, and wherein a flexible resilient cord member of substantially uniform cross section is attached at opposite ends of the pole section assembly, said cord is normally under tension and said cord is threaded through said pole sections and through said hollowed connector joint, comprising: a two piece connector joint assembly wherein first and second pieces are adapted for separation and for mating relation, and wherein the hollow within said first and second pieces of said connector joint assembly has a substantially uniform cross section, and; a rigid tubular member disposed within the hollow of said connector joint assembly with said flexible cord member threaded therethrough; said tubular member having a respective hollow configuration of uniform cross section compatible with said uniform cross section of said cord member and larger in dimensions with respect thereto such that said cord member is free to move within said tubular member; said tubular member having an outer configuration compatible with the configuration of the cross section of the hollow within said connector joint assembly and smaller in dimensions with respect thereto such that said tubular member is moveable in contiguous relation within the hollow of said connector joint assembly when said pole sections are selectively oriented with respect each other such that the hollows in each of said first and second pieces of said joint assembly are in axial alignment; said tubular member including restraint means adapted to limit the travel of said tubular member within said hollow of said connector joint assembly such that in a first position said tubular member is completely contained within one piece of said joint assembly and in a second position said tubular member is within both of said pieces of said connector joint assembly.
Claim 3
Dependent Claim
23 words
A hollowed connector joint as defined in claim 1 wherein said two piece connector joint assembly is a ball and socket joint assembly.
Claim 4
Dependent Claim
87 words
A hollowed connector joint as defined in claim 2 wherein said one piece of said joint assembly which completely contains said tubular member in said first position includes an axially extending slot with a transverse notch at the end most remote from the other piece of said joint assembly and said tubular member includes a projection therefrom which is adapted for movement within said slot and said notch, said notch adapted to retain said tubular means in said first position when said projection is in said notch.
Claim 5
Dependent Claim
37 words
A hollowed connector joint as defined in claim 3 wherein said joint assembly includes means for biasing said tubular member such that when said projection is in said slot said tubular member is in said second position.
