Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 105 words
An elongated retaining device comprising: a body member having one end portion thereof adapted to support a supported member therefrom and having an outwardly biased bifurcated portion adjacent the other end portion thereof; and each of the legs of said bifurcated portion including retaining means extending longitudinally therealong which are adapted to be cooperable with a seating portion of a supporting member to selectively retain said body member at any of a plurality of locations therealong with respect to such a seating portion by overcoming the bias of said bifurcated portion and seating a selected section of said retaining means on such a seating portion.
Claim 2
Dependent Claim 105 words
An elongated retaining device comprising: a body member having one end portion thereof adapted to support a supported member therefrom and having an outwardly biased bifurcated portion adjacent the other end portion thereof; and each of the legs of said bifurcated portion including retaining means extending longitudinally therealong which are adapted to be cooperable with a seating portion of a supporting member to selectively retain said body member at any of a plurality of locations therealong with respect to such a seating portion by overcoming the bias of said bifurcated portion and seating a selected section of said retaining means on such a seating portion.
Claim 3
Dependent Claim 27 words
A retaining device as specified in claim 1 wherein said retaining means are a plurality of ratchet teeth extending longitudinally along the exterior sides of said legs.
Claim 4
Dependent Claim 33 words
A retaining device as specified in Claim 1 wherein said body member comprises a pair of independent elongated sections which are pivotally joined together intermediate the axial ends thereof in scissor like fashion.
Claim 5
Dependent Claim 26 words
A retaining device as specified in claim 3 wherein said legs are the portion of said independent elongated sections on one side of the pivot axis.
Claim 6
Dependent Claim 32 words
A retaining device as specified in claim 4 additionally including means applying an inward biasing force to the portion of said independent elongated sections on the other side of the pivot axis.
Claim 7
Dependent Claim 39 words
A retaining device as specified in claim 5 additionally including an additional elongated member adapted to carry such a supported member adjacent one end portion thereof and being supported by said first mentioned member adjacent the other end thereof.
Claim 8
Dependent Claim 35 words
A retaining device as specified in claim 6 additionally including a biasing means disposed intermediate said first mentioned member and said another member and being cooperable therewith to bias said members away from each other.
Claim 9
Dependent Claim 41 words
