Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
94 words
A suspension system comprising a one part holder adapted to be fixed to one of a wall and a ceiling, said holder having at least two apertures therein disposed in opposition to each other; each said aperture having a constricted section and a widened section above said constricted section; and a support bar having a widened portion sized to pass longitudinally through a widened section of one of said apertures and a constricted portion sized to fit transversely into said constricted section of said one aperture to lock said support member in said holder.
Claim 2
Dependent Claim
94 words
A suspension system comprising a one part holder adapted to be fixed to one of a wall and a ceiling, said holder having at least two apertures therein disposed in opposition to each other; each said aperture having a constricted section and a widened section above said constricted section; and a support bar having a widened portion sized to pass longitudinally through a widened section of one of said apertures and a constricted portion sized to fit transversely into said constricted section of said one aperture to lock said support member in said holder.
Claim 3
Dependent Claim
25 words
A suspension system as set forth in claim 1 wherein said support bar has a pair of said constricted portions disposed in longitudinally spaced relation.
Claim 4
Dependent Claim
26 words
A suspension system as set forth in claim 2 wherein said support bar is cylindrical and has a pair of circumferential grooves defining said constricted portions.
Claim 5
Dependent Claim
