Abstract
Abstract A joint is formed by positioning a connector within channel members to be joined which has a rotatable eccentric with different length radii to engage the lateral edges of the channels, and rotation of the eccentric causes its longer length side to engage the channel edges first, bringing the channel members tightly together as they are fastened.

Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
96 words
A joint comprising: (a) two lengths of grooved metal sections; (b) a connector having end portions insertable into a groove in each of said sections; (c) a cam on each of said connector end portions; and (d) means on each said cam for turning it laterally into locking engagement with first and second edges of its associated groove; (e) each said cam being eccentric and having a first side which upon turning of said cam engages the first edge of said groove before a second side of said cam engages the second edge of said groove.
Claim 2
Dependent Claim
96 words
A joint comprising: (a) two lengths of grooved metal sections; (b) a connector having end portions insertable into a groove in each of said sections; (c) a cam on each of said connector end portions; and (d) means on each said cam for turning it laterally into locking engagement with first and second edges of its associated groove; (e) each said cam being eccentric and having a first side which upon turning of said cam engages the first edge of said groove before a second side of said cam engages the second edge of said groove.
