Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
108 words
A connecting joint seat member device comprising a base wall; at least one pair of side walls, the side walls of any pair extending perpendicularly from said base wall and parallel with each other in side-by-side relationship; said base wall and each pair of said side walls defining a channel adapted to receive a construction panel member; and at least two conical locking projections, each locking projection formed integrally with said base wall, extending parallel with a pair of said side walls and within the channel defined by said last-named pair of side walls and adapted to penetrate and hold a construction panel member received in that channel.
Claim 2
Dependent Claim
108 words
A connecting joint seat member device comprising a base wall; at least one pair of side walls, the side walls of any pair extending perpendicularly from said base wall and parallel with each other in side-by-side relationship; said base wall and each pair of said side walls defining a channel adapted to receive a construction panel member; and at least two conical locking projections, each locking projection formed integrally with said base wall, extending parallel with a pair of said side walls and within the channel defined by said last-named pair of side walls and adapted to penetrate and hold a construction panel member received in that channel.
