Claim 7
Dependent Claim
90 words
A joint for connecting members as defined in claim 5: wherein said camming means is comprised of an inner edge portion of said access means; wherein said engagement means is oriented essentially perpendicularly to said longitudinal axis of said male portion; wherein said engagement means is continuously disposed in said male portion; and wherein said camming means is further comprised of a generally conical surface carried by said engagement means for engaging said inner edge portion of said access means to lock said female member means to said male portion.
Claim 8
Dependent Claim
61 words
A joint for connecting members as defined in claim 2: wherein said engagement means is continuously disposed in said male portion when said male portion is inserted in said female member means; and wherein said engagement means is continuously disposed within the ambit of an outer surface of said female member means after said female member means receives said male portion.
Claim 9
Dependent Claim
61 words
A joint for connecting members as defined in claim 7 further comprising: abutment means associated with said male portion for axially positioning said camming means with respect to said engagement means; and key means associated with said male portion for engagement with interior portions of said female member means to rotationally position said camming means with respect to said engagement means.
Claim 10
Dependent Claim
156 words
A joint for connecting members comprising: a female member; a hub member having a male portion for operable insertion into at least a portion of said female member; orienting means disposed on said male portion for orienting said female member relative to said engagement means; abutment means comprising a portion of said hub member for abutting said female member to limit the longitudinal extent to which said male portion may be inserted within said female member; camming engagement means carried by said male portion and moveable outwardly from a longitudinal axis of said male portion for engaging an inner portion of said female member; and access means disposed in said female member through which said engagement means is manipulatable outwardly from said longitudinal axis when said female member and said male portions are united to cammingly engage said engageable inner portion to rigidly lock said female member against said abutment means and against said male portion.
Claim 11
Dependent Claim
156 words
A joint for connecting members comprising: a female member; a hub member having a male portion for operable insertion into at least a portion of said female member; orienting means disposed on said male portion for orienting said female member relative to said engagement means; abutment means comprising a portion of said hub member for abutting said female member to limit the longitudinal extent to which said male portion may be inserted within said female member; camming engagement means carried by said male portion and moveable outwardly from a longitudinal axis of said male portion for engaging an inner portion of said female member; and access means disposed in said female member through which said engagement means is manipulatable outwardly from said longitudinal axis when said female member and said male portions are united to cammingly engage said engageable inner portion to rigidly lock said female member against said abutment means and against said male portion.
