Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 168 words
An article of the type described comprising a weight element having two oppositely facing substantially planar sides bordered by two opposite side edges and two ends, said planar sides being the major surfaces of said weight, said side edges being relatively narrow with respect to the width of said planar sides, at least one end piece, said end piece being generally "U" shaped, said end piece being dimensioned such that the arms of said "U" fit over and embrace the opposite side edges of said weight with said major surfaces extending between said arms, the arms of said "U" being resiliently springable apart, a catch element on each of said arms of said "U", a second catch element on each of the opposite side edges of said weight, said end piece when in position with its arms embracing said weight having the catch elements of its arms engaged with the catch elements of said weight for retaining said end piece in position on the end of said weight.
Claim 2
Dependent Claim 168 words
An article of the type described comprising a weight element having two oppositely facing substantially planar sides bordered by two opposite side edges and two ends, said planar sides being the major surfaces of said weight, said side edges being relatively narrow with respect to the width of said planar sides, at least one end piece, said end piece being generally "U" shaped, said end piece being dimensioned such that the arms of said "U" fit over and embrace the opposite side edges of said weight with said major surfaces extending between said arms, the arms of said "U" being resiliently springable apart, a catch element on each of said arms of said "U", a second catch element on each of the opposite side edges of said weight, said end piece when in position with its arms embracing said weight having the catch elements of its arms engaged with the catch elements of said weight for retaining said end piece in position on the end of said weight.
Claim 3
Dependent Claim 140 words
A slat for a vertically slatted blind comprising an elongated slat, a pocket at one end of said slat, a weight having two opposite side edges and two ends, said weight being positioned in said pocket, an end piece having a substantially "U" shape, the arms of said "U" embracing the opposite side edges of said weight, said arms also being within said pocket, catch means on each of said arms, catch means on each opposite edge of said weight engaged with the catch means of said arms to retain said end piece in position on one end of said weight, at least one ear extending laterally from said end piece at substantially a right angle to said arms, said slat having longitudinal side edges, and said ear being exterior of said pocket adjacent a longitudinal edge of said slat.
Claim 4
Dependent Claim 140 words
A slat for a vertically slatted blind comprising an elongated slat, a pocket at one end of said slat, a weight having two opposite side edges and two ends, said weight being positioned in said pocket, an end piece having a substantially "U" shape, the arms of said "U" embracing the opposite side edges of said weight, said arms also being within said pocket, catch means on each of said arms, catch means on each opposite edge of said weight engaged with the catch means of said arms to retain said end piece in position on one end of said weight, at least one ear extending laterally from said end piece at substantially a right angle to said arms, said slat having longitudinal side edges, and said ear being exterior of said pocket adjacent a longitudinal edge of said slat.
Claim 5
Dependent Claim 53 words
The article of claim 2 including a second like end piece engaged with said weight at the end opposite to that of the first mentioned end piece, said second end piece having its ear lying adjacent the longitudinal edge of said slat opposite to that adjacent the ear of the first end piece.
Claim 6
Dependent Claim 199 words
An article of the type described comprising a weight element having two oppositely facing substantially planar sides bordered by two opposite side edges and two ends, said planar sides being the major surfaces of said weight, said side edges being relatively narrow with respect to said planar sides, at least one end piece, said end piece being generally "U" shaped, said end piece being dimensioned such that the arms of said "U" fit over and embrace the opposite side edges of said weight, the arms of said "U" being resiliently springable apart, a catch element on each of said arms of said "U", a second catch element on each of the opposite side edges of said weight, said end piece when in position with its arms embracing said weight having the catch elements of its arms engaged with the catch elements of said weight for retaining said end piece in position on the end of said weight, said end piece including at least one brace extending from an arm to the middle portion of said "U" shaped end piece, and said brace and said end piece is in position on said weight lying to one side of said weight.
Claim 7
Dependent Claim 199 words
An article of the type described comprising a weight element having two oppositely facing substantially planar sides bordered by two opposite side edges and two ends, said planar sides being the major surfaces of said weight, said side edges being relatively narrow with respect to said planar sides, at least one end piece, said end piece being generally "U" shaped, said end piece being dimensioned such that the arms of said "U" fit over and embrace the opposite side edges of said weight, the arms of said "U" being resiliently springable apart, a catch element on each of said arms of said "U", a second catch element on each of the opposite side edges of said weight, said end piece when in position with its arms embracing said weight having the catch elements of its arms engaged with the catch elements of said weight for retaining said end piece in position on the end of said weight, said end piece including at least one brace extending from an arm to the middle portion of said "U" shaped end piece, and said brace and said end piece is in position on said weight lying to one side of said weight.
Claim 8
Dependent Claim 47 words
The article of claim 4 in which said end piece includes at least one guide lug adjacent the terminus of one of said arms, said guide lug when said end piece is engaged with said weight lying to the opposite side of said weight from said brace.
Claim 9
Dependent Claim 44 words
The article of claim 5 in which the arms of said end piece adjacent their termini include cam means for cooperation with the opposite side edges of said weight to aid in springing said arms apart during assembly of the weight and end piece.
