Claims Analysis

Total Claims: 13
Claim 1
Independent Claim 96 words
A sawhorse bracket comprising, a central bracket member attachable to a beam and having downwardly extending, aligned hinge posts, a pair of opposed leg members, each attachable to an end of a beam, said leg members having upwardly extending, aligned hinge posts interleaving with aligned hinge posts of the other leg member and the downwardly extending hinge posts of said central bracket member, and a removable hinge pin for passage through said hinge posts of said leg members and said central bracket member, whereby said leg members may be removably joined to said central bracket member.
Claim 2
Dependent Claim 96 words
A sawhorse bracket comprising, a central bracket member attachable to a beam and having downwardly extending, aligned hinge posts, a pair of opposed leg members, each attachable to an end of a beam, said leg members having upwardly extending, aligned hinge posts interleaving with aligned hinge posts of the other leg member and the downwardly extending hinge posts of said central bracket member, and a removable hinge pin for passage through said hinge posts of said leg members and said central bracket member, whereby said leg members may be removably joined to said central bracket member.
Claim 3
Dependent Claim 19 words
The bracket of claim 1 wherein said central bracket member has sidewalls shaped for receiving a horizontally disposed beam.
Claim 4
Dependent Claim 25 words
The bracket of claim 1 wherein each of said opposed leg members have sidewalls shaped for receiving a downwardly extending beam forming a sawhorse leg.
Claim 5
Dependent Claim 47 words
The bracket of claim 1 wherein the angular position of said central bracket member relative to said opposed leg members is limited by a pair of latches and catches, one latch and catch on each side of said central bracket member associated with one opposed leg member.
Claim 6
Dependent Claim 203 words
A sawhorse bracket assembly comprising, a central bracket member having an upper portion with sidewalls adapted to receive and support a horizontally extending beam in a nested relation therewith, said central member having a lower portion with sidewalls connected to sidewalls of said upper portion, said lower portion including downwardly extending hinge posts aligned parallel to the direction in which a horizontal beam would be aligned in said upper portion, a pair of opposed leg members, one leg member having upwardly extending hinge posts interleaving with hinge posts of the other leg member and the downwardly extending hinge posts of said central bracket member, each of said leg members having sidewalls supporting said hinge posts, said sidewalls of each leg member having an upper and lower region extending radially outwardly relative to said hinge posts, with upper regions of opposite leg members capable of making an open stance sawhorse, and the lower regions adapted to receive and support a downwardly extending beam in a nested relation therewith, forming an angularly adjustable sawhorse leg, and a removable hinge pin for passage through said hinge posts, whereby the open stance of said sawhorse may be closed or said opposed legs removed from the central bracket.
Claim 7
Dependent Claim 203 words
A sawhorse bracket assembly comprising, a central bracket member having an upper portion with sidewalls adapted to receive and support a horizontally extending beam in a nested relation therewith, said central member having a lower portion with sidewalls connected to sidewalls of said upper portion, said lower portion including downwardly extending hinge posts aligned parallel to the direction in which a horizontal beam would be aligned in said upper portion, a pair of opposed leg members, one leg member having upwardly extending hinge posts interleaving with hinge posts of the other leg member and the downwardly extending hinge posts of said central bracket member, each of said leg members having sidewalls supporting said hinge posts, said sidewalls of each leg member having an upper and lower region extending radially outwardly relative to said hinge posts, with upper regions of opposite leg members capable of making an open stance sawhorse, and the lower regions adapted to receive and support a downwardly extending beam in a nested relation therewith, forming an angularly adjustable sawhorse leg, and a removable hinge pin for passage through said hinge posts, whereby the open stance of said sawhorse may be closed or said opposed legs removed from the central bracket.
Claim 8
Dependent Claim 40 words
The bracket of claim 5 wherein each leg member has an upwardly projecting latch and said central bracket member has two latch retaining catches, each catch disposed in an opposite sidewall for securing a latch of a respective leg member.
Claim 9
Dependent Claim 26 words
The bracket of claim 5 wherein the upper portion of said central bracket member is separated from the lower portion by a horizontally disposed base plate.
Claim 10
Dependent Claim 26 words
The bracket of claim 5 wherein said central bracket member has holes defined in the sidewalls thereof for attachment of fasteners to a transverse beam therein.
Claim 11
Dependent Claim 24 words
The bracket of claim 5 wherein said leg members have holes defined in the sidewalls thereof for attachment of fasteners to downwardly extending beams.
Claim 12
Dependent Claim 21 words
The bracket of claim 5 wherein each leg member has a top wall member spanning the sidewalls at their uppermost extent.
Claim 13
Dependent Claim 36 words
The bracket of claim 10 wherein said upper cover of each leg member has an upwardly projecting latch extending therefrom and said central member has two latch retaining catches, each catch disposed in an opposite sidewall.
