Abstract
Abstract A connector for joining a first elongated tube and a second tube having a hollow end portion at an angle to the first tube includes an integral body having a saddle to engage the outer surface of the first tube and a split pin portion resiliently deflectable relative to the saddle. The split pin has a passageway extending to the longitudinal length thereof in communication with an opening in the saddle portion. The split pin is forced apart to engage and grip the inside surface of the hollow end portion of the second tube upon receiving an elongated pin through the opening in the saddle into the passageway.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
149 words
A joint consisting of a first elongated member, a second elongated member having a hollow end portion, a connector for connecting said second elongated member at an angle to said first elongated member, said connector comprising an integral body having a saddle portion engaging the outer surface of said first elongated member, and a split pin portion, said split pin portion being resiliently deflected relative to said saddle portion and projecting into and in gripping engagement with the hollow end portion of said second elongated member, and an elongated pin projecting through said first elongated member, passing through an opening in said saddle portion in engagement with the walls of the opening, and projecting into a passageway extending the longitudinal length of said split pin portion and resiliently deflecting said split pin portion, said elongated pin having a cylindrical shank of diameter slightly greater than that of the passageway.
Claim 2
Dependent Claim
149 words
A joint consisting of a first elongated member, a second elongated member having a hollow end portion, a connector for connecting said second elongated member at an angle to said first elongated member, said connector comprising an integral body having a saddle portion engaging the outer surface of said first elongated member, and a split pin portion, said split pin portion being resiliently deflected relative to said saddle portion and projecting into and in gripping engagement with the hollow end portion of said second elongated member, and an elongated pin projecting through said first elongated member, passing through an opening in said saddle portion in engagement with the walls of the opening, and projecting into a passageway extending the longitudinal length of said split pin portion and resiliently deflecting said split pin portion, said elongated pin having a cylindrical shank of diameter slightly greater than that of the passageway.
Claim 3
Dependent Claim
16 words
The joint of claim 1, wherein said first and second elongated members are hollow cylindrical tubes.
Claim 4
Dependent Claim
29 words
The joint of claim 1, wherein said split pin portion has the same external shape as the internal surface of said hollow end portion of said second elongated member.
Claim 5
Dependent Claim
25 words
The joint of claim 1, wherein said elongated pin is a cylindrical smooth surfaced pin having a diameter slightly greater than that of said passageway.
Claim 6
Dependent Claim
13 words
The joint of claim 1, wherein said elongated pin has a tapered nose.
Claim 7
Dependent Claim
19 words
The joint of claim 2, wherein said saddle portion has a diameter substantially that of the second elongated member.
Claim 8
Dependent Claim
158 words
A connector assembly for joining a first elongated member and a second member having a hollow end portion at an angle to said first elongated member, comprising an elongated pin, an integral body including a saddle portion adapted to engage the outer surface of said first elongated member, said saddle portion having an opening formed therein to receive therethrough in touching engagement said elongateD pin, and a split pin portion, said split pin portion being resiliently deflectable relative to said saddle portion, said split pin portion having a passageway extending the longitudinal length thereof in communication with the opening in said saddle portion, said elongated pin having a cylindrical shank of diameter slightly greater than that of the passageway, said split pin portion being adapted to be forced apart so that peripheral portions thereof engage and grip the inside surface of said hollow end portion of said second elongated member upon receiving said elongated pin in the passageway.
Claim 9
Dependent Claim
158 words
A connector assembly for joining a first elongated member and a second member having a hollow end portion at an angle to said first elongated member, comprising an elongated pin, an integral body including a saddle portion adapted to engage the outer surface of said first elongated member, said saddle portion having an opening formed therein to receive therethrough in touching engagement said elongateD pin, and a split pin portion, said split pin portion being resiliently deflectable relative to said saddle portion, said split pin portion having a passageway extending the longitudinal length thereof in communication with the opening in said saddle portion, said elongated pin having a cylindrical shank of diameter slightly greater than that of the passageway, said split pin portion being adapted to be forced apart so that peripheral portions thereof engage and grip the inside surface of said hollow end portion of said second elongated member upon receiving said elongated pin in the passageway.
Claim 10
Dependent Claim
14 words
The connector of claim 7 wherein said split pin portion consists of two parts.
Claim 11
Dependent Claim
29 words
The connector of claim 7 wherein the whole of the peripheral portion of said split pin portion engages and grips the inside surface of said second hollow elongated member.
