Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
198 words
A drapery support comprising in combination; a curtain rod comprising a pair of hollow telescoping tubes; a helical compression spring within said tubes; means for securing said spring to one said tube; means for threadedly engaging said spring to the other said tube whereby twisting said tubes relative to each other effectively lengthens the rod; a curtain; a finial at each end of said rod, having an enlarged middle part; rings mounted on said rod; means connecting said curtain to said rings; the inside dimensions of the opening of said rings being limited to prevent said rings from passing over the enlarged middle part of said finial; an annular groove in said finial nearer to the end of said finial than said middle part the diameter of said annular groove being smaller than the minimum inside diameter of said rings whereby said annular groove is adapted to receive and retain a ring adjacent to the end of said finial; a pair of walls in opposed relation defining a curtain receiving opening; and said rod mounted between said walls under spring compression supporting said curtain by rings on said rod and by one ring in each said annular groove.

A drapery support comprising in combination; a curtain rod comprising a pair of hollow telescoping tubes; a helical compression spring within said tubes; means for securing said spring to one said tube; means for threadedly engaging said spring to the other said tube whereby twisting said tubes relative to each other effectively lengthens the rod; a curtain; a finial at each end of said rod, having an enlarged middle part; rings mounted on said rod; means connecting said curtain to said rings; the inside dimensions of the opening of said rings being limited to prevent said rings from passing over the enlarged middle part of said finial; an annular groove in said finial nearer to the end of said finial than said middle part the diameter of said annular groove being smaller than the minimum inside diameter of said rings whereby said annular groove is adapted to receive and retain a ring adjacent to the end of said finial; a pair of walls in opposed relation defining a curtain receiving opening; and said rod mounted between said walls under spring compression supporting said curtain by rings on said rod and by one ring in each said annular groove.
Claim 3
Dependent Claim
29 words
The combination defined in claim 1 further characterized by the supporting level of said annular groove being substantially at the same height as the supporting level of said rod.
Claim 4
Dependent Claim
60 words
The combination defined in claim 1 further characterized by an annular bead at the end of said finial adjacent to said annular groove having a diameter larger than said annular groove but smaller than the inside diameter of said rings whereby said rings may be retained in said grooves by gravity while said rod is being lifted into operative position.
