Abstract: |
A pair of members hingedly connected together for relative rotation about an axis, one of the members including a stud extending outwardly therefrom generally coaxially with the axis, the other member defining a socket for receiving the stud, and the stud and socket being so sized and shaped that relative rotation of the two in one direction produces forces tending to cause relative rotation in the opposite direction.

What is claimed is:
1. In a hair clip comprising
- first and second members, each of said members including a gripping portion and a hinge portion, said hinge portions being connected to provide relative rotation of said members about an axis between a first position wherein said gripping portions are in engagement and a second position wherein said gripping portions are spaced apart, said hinge portion of said first member including a pair of studs extending outwardly therefrom on opposite sides thereof generally coaxially with each other and said axis, and said hinge portion of said second member defining a pair of spaced sockets, each of said sockets being adapted for receiving one of said studs, that improvement wherein:
- said first and second members are of resilient organic plastic;
- each of said studs has a first dimension and a second dimension measured in a plane perpendicular to said axis, said second dimension being measured along a line generally perpendicular to the line along which said first dimension is measured and being less than said first dimension;
- each of said sockets has an open portion forming a throat having a width extending generally perpendicular to said axis and a first dimension measured in a line perpendicular to said axis and along a line generally parallel to the width of said throat, said first dimension of said socket being less than said first dimension of said stud and not substantially less than said second dimension of said stud;
- the angle of divergence between the lines along which said first dimension of each of said sockets and said second dimension of the one of said studs associated therewith is not less than 5° when said members are in said first position whereby said studs and sockets urge said gripping portions toward each other with a positive force in said first position; and,
- rotation of said studs relative to said sockets in a direction so as to move said gripping portions toward said second position and increase said angle of divergence causes portions of said second member defining said sockets to exert on said studs force tending to rotate said studs relative to said sockets in a direction so as to decrease said angle and move said gripping portions toward said first position.
