Abstract
Abstract A hair roller is described having first and second flexible, generally planar roller members which are hinge coupled and are deflectable from a generally planar configuration into a body having a generally cylindrically shaped configuration. Edge segments of the members are preformed to have arcuate cross sectional configurations for causing the hair roller body to conform to a circular cross sectional configuration.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
233 words
An improved hair roller comprising in combination, a pair of resiliently flexible rectangular shaped elongated substantially flat roller members each having a pair of opposed elongated marginal segments terminating in longitudinal edges, said roller members arranged in overlying relationship to each other with said marginal segments arranged in adjacent parallel pairs extending in the longitudinal direction, means attached to each of said adjacent pairs of said marginal segments in bridging relationship to at least one of said longitudinal edges of said pairs of marginal segments for hinge coupling one of said roller members to the other of said roller members, said hinge-coupled members being resiliently deflectable from said overlying relationship to an arcuate shaped spaced apart relationship to form a generally hollow cylindrical shaped roller body, means attached to at least one of said roller members for releasably maintaining said roller body in said cylindrical shaped configuration, said roller body being substantially resistant to bending and buckling from externally applied finger force and the resiliency of said roller members urging said roller body into a substantially flat configuration upon release of said maintaining means, the improvement comprising in that said marginal segments each having a preformed arc shaped transverse cross sectional configuration for conforming the surface of the marginal segments to the circular arc of said cylindrical shaped configuration of the roller body upon deflecting said hinge-coupled roller members into said roller body.
Claim 2
Dependent Claim
233 words
An improved hair roller comprising in combination, a pair of resiliently flexible rectangular shaped elongated substantially flat roller members each having a pair of opposed elongated marginal segments terminating in longitudinal edges, said roller members arranged in overlying relationship to each other with said marginal segments arranged in adjacent parallel pairs extending in the longitudinal direction, means attached to each of said adjacent pairs of said marginal segments in bridging relationship to at least one of said longitudinal edges of said pairs of marginal segments for hinge coupling one of said roller members to the other of said roller members, said hinge-coupled members being resiliently deflectable from said overlying relationship to an arcuate shaped spaced apart relationship to form a generally hollow cylindrical shaped roller body, means attached to at least one of said roller members for releasably maintaining said roller body in said cylindrical shaped configuration, said roller body being substantially resistant to bending and buckling from externally applied finger force and the resiliency of said roller members urging said roller body into a substantially flat configuration upon release of said maintaining means, the improvement comprising in that said marginal segments each having a preformed arc shaped transverse cross sectional configuration for conforming the surface of the marginal segments to the circular arc of said cylindrical shaped configuration of the roller body upon deflecting said hinge-coupled roller members into said roller body.
Claim 3
Dependent Claim
55 words
The improved hair roller of claim 1 wherein the arc-shaped marginal segments of a first of said roller members are formed in an opposite direction with respect to the arc-shaped curvature of the marginal segments of a second of said roller members to oppose outward deflection of the roller members and provide said circular conformity.
Claim 4
Dependent Claim
36 words
The improved hair roller of claim 2 wherein said hinge coupling is provided by the marginal segments of said first member having edge portions hinge-coupled to surface portions of the marginal segments of said second member.
Claim 5
Dependent Claim
68 words
The improved hair roller of claim 2 wherein said hinge coupling is provided by one of the marginal segments of said first member having an edge portion hinge-coupled to the surface portion of the marginal segment of said second member and the other marginal segment of said second member having an edge portion hinge coupled to a surface portion of the other marginal segment of said first member.
