Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
114 words
A connector for building constructions and the like comprising in cross-section a four-sided box-shaped central portion having fins in pairs projecting outwardly from each of the corners thereof at right angles to each other and at right angles to the adjacent outer surfaces of the central portion, the said fins forming with the adjacent outer surfaces of the central portion four oppositely disposed substantially right-angular longitudinal channels wherein mitred ends of intersecting structural members may be fitted to the channels to engage with the fins and to project substantially at right angles to one another such that the longitudinal axis of the structural members align diagnally with opposite corners of the said central portion.
Claim 2
Dependent Claim
114 words
A connector for building constructions and the like comprising in cross-section a four-sided box-shaped central portion having fins in pairs projecting outwardly from each of the corners thereof at right angles to each other and at right angles to the adjacent outer surfaces of the central portion, the said fins forming with the adjacent outer surfaces of the central portion four oppositely disposed substantially right-angular longitudinal channels wherein mitred ends of intersecting structural members may be fitted to the channels to engage with the fins and to project substantially at right angles to one another such that the longitudinal axis of the structural members align diagnally with opposite corners of the said central portion.
Claim 3
Dependent Claim
34 words
The connector as claimed in claim 1 wherein the fins are substantially thicker in cross-section than the side of the box-shaped central portion and inner corners of the box-shaped portion are provided with radii.
