Abstract
Abstract A connector assembly for connecting two panels edge to edge with a joint opening therebetween, each of the panels having a groove extending longitudinally along such edge thereof. The connector assembly comprises: a pair of oppositely disposed, elongated first and second members having first and second plug means adapted to be secured to the panels along their respective panel grooves; a pair of opposed first and second front arm means adapted to be disposed adjacent to one face of the joint opening, and carried by the first and second members along their respective front longitudinal edges; a pair of opposed first and second rear arm means adapted to be disposed adjacent to the opposite face of the joint opening, and carried by the first and second members along their respective rear longitudinal edges; and a pair of elongated front and rear third members for covering the joint opening on opposite faces, and holding the pair of front arm means and the pair of rear arm means, respectively, whereby the first and second members are secured to each other.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
198 words
A connector assembly for connecting two panels edge-to-edge with a joint-opening therebetween, each of the panels having a prefinished groove extending longitudinally along such edge thereof, said connector assembly comprising: (a) a pair of oppositely disposed, elongated first and second members having first and second plug means adapted to be slidably inserted in and secured to the panels along their respective prefinished panel grooves; (b) a pair of opposed spaced-apart first and second front arm means adapted to be disposed adjacent to one face of the joint-opening, and carried by said first and second members along their respective front longitudinal edges; (c) a pair of opposed spaced-apart first and second rear arm means adapted to be disposed adjacent to the opposite face of the joint-opening, and carried by said first and second members along their respective rear longitudinal edges; and (d) a pair of elongated front and rear third members for covering the joint opening on opposite faces, and each having portions for projecting into said joint opening and holding said pair of front arm means and said pair of rear arm means, respectively, whereby said first and second members are secured to each other in spaced-apart relation.
Claim 2
Dependent Claim
198 words
A connector assembly for connecting two panels edge-to-edge with a joint-opening therebetween, each of the panels having a prefinished groove extending longitudinally along such edge thereof, said connector assembly comprising: (a) a pair of oppositely disposed, elongated first and second members having first and second plug means adapted to be slidably inserted in and secured to the panels along their respective prefinished panel grooves; (b) a pair of opposed spaced-apart first and second front arm means adapted to be disposed adjacent to one face of the joint-opening, and carried by said first and second members along their respective front longitudinal edges; (c) a pair of opposed spaced-apart first and second rear arm means adapted to be disposed adjacent to the opposite face of the joint-opening, and carried by said first and second members along their respective rear longitudinal edges; and (d) a pair of elongated front and rear third members for covering the joint opening on opposite faces, and each having portions for projecting into said joint opening and holding said pair of front arm means and said pair of rear arm means, respectively, whereby said first and second members are secured to each other in spaced-apart relation.
Claim 3
Dependent Claim
81 words
A connector assembly according to claim 1, each of said third members having a generally π-shaped transverse cross section defined by a base for covering the joint opening on its one face and a single pair of spaced legs projecting perpendicularly from one side of said base and terminating in inwardly directed snap-locking flanges, said pair of front arm means and said pair of rear arm means being respectively disposed between said pair of legs of one of said third members.
Claim 4
Dependent Claim
86 words
A connector assembly according to claim 1, each of said first and second slidably insertable plug means having a substantially U-shaped transverse cross-section defined by a pair of spaced side walls projecting perpendicularly from one side of one of said first and second members and terminating in an end wall extending between said side walls, each of such two end walls having at least one hole through which at least one fastening screw may extend into one of the panels from the bottom of its groove.
Claim 5
Dependent Claim
73 words
A connector assembly according to claim 1, each of said first and second slidably insertable plug means including a pair of spaced arcuate walls projecting substantially perpendicularly from one side of one of said first and second members, each of said arcuate walls having a corrugation extending longitudinally on and along its contacting exterior surface for retaining said first and second plug means firmly in the respective panel grooves and engageable directly therewith.
Claim 6
Dependent Claim
56 words
A connector assembly according to claim 1, comprising a pair of elastomeric elongated front and rear sealing strips disposed between said pair of front arm means and between said pair of rear arm means, respectively, and carried by one of said pair of front arm means and one of said pair of rear arm means, respectively.
Claim 7
Dependent Claim
43 words
A connector assembly according to claim 5, each of said front and rear arm means having a recess opening toward the joint-opening and extending longitudinally on and along one side thereof, each of said sealing strips being retained in one of said recesses.
