Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
174 words
Construction tool for metal framing elements having a generally U-shaped cross-sectional configuration consisting of a bottom wall and two side walls with the side walls being substantially parallel with each other and the distance between the side walls being defined as the width of the framing element, said tool comprising: (a) a main body portion comprising: (1) a bottom surface which is adapted to rest on the bottom wall of the framing element, (2) a top surface which is opposite said bottom surface, and (3) a pair of opposite end surfaces, the distance between said end surfaces being equal to the width of the framing element, each of said end surfaces having a recess which extends from said bottom surface to said top surface, said recess being substantially at a right angle to said bottom surface, and (b) a handle which is attached to the main body portion, said handle having an elongated shank portion having a longitudinal axis which is at an angle to said bottom surface and to each of said recesses.
Claim 2
Dependent Claim

Construction tool for metal framing elements having a generally U-shaped cross-sectional configuration consisting of a bottom wall and two side walls with the side walls being substantially parallel with each other and the distance between the side walls being defined as the width of the framing element, said tool comprising: (a) a main body portion comprising: (1) a bottom surface which is adapted to rest on the bottom wall of the framing element, (2) a top surface which is opposite said bottom surface, and (3) a pair of opposite end surfaces, the distance between said end surfaces being equal to the width of the framing element, each of said end surfaces having a recess which extends from said bottom surface to said top surface, said recess being substantially at a right angle to said bottom surface, and (b) a handle which is attached to the main body portion, said handle having an elongated shank portion having a longitudinal axis which is at an angle to said bottom surface and to each of said recesses.
Claim 3
Dependent Claim
20 words
Construction tool as recited in claim 1, wherein each of said recesses is defined by a pair of spaced flanges.
Claim 4
Dependent Claim
28 words
Construction tool as recited in claim 2, wherein each of said flanges has a vertical end surface and the end surfaces of each pair of flanges are co-planar.
Claim 5
Dependent Claim
24 words
Construction tool as recited in claim 1, wherein said handle includes a hand grip portion attached to the outer end of said shank portion.
Claim 6
Dependent Claim
