Abstract
Abstract The device is an expansible and contractable hair curler. It is generally cylindrical having a plurality of arcuate segments disposed about a central axis. The segments are held together by means within the curler which are connected to the various segments and movable axially to cause the segments to move radially inwardly and outwardly for changing the size of the curler. The segments are held together at the ends by adjustable or flexible means to allow for the change in diameter.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
66 words
An expansible and contractable hair curler comprising a group of at least three axial segments disposed about a central axis, the segments having an arcuate configuration, the segments normally forming a generally cylindrical hair curler, and means for holding the segments in position around the axis and for simultaneously moving them radially towards and away from the axis whereby to change the size of the curler.
Claim 2
Dependent Claim
66 words
An expansible and contractable hair curler comprising a group of at least three axial segments disposed about a central axis, the segments having an arcuate configuration, the segments normally forming a generally cylindrical hair curler, and means for holding the segments in position around the axis and for simultaneously moving them radially towards and away from the axis whereby to change the size of the curler.
Claim 3
Dependent Claim
36 words
A hair curler as in claim 1 including means at the ends of the curler holding the segments together in a manner whereby to allow them to move radially towards and away from the central axis.
Claim 4
Dependent Claim
44 words
A curler as in claim 1 wherein said means for moving the segments comprises a member disposed within the curler and movable axially and having connections to angularly spaced segments arranged whereby axial movement of the member causes radial movement of the said segments.
Claim 5
Dependent Claim
24 words
A curler as in claim 3 wherein said connections comprise pairs of parallel links connected between the said member and each of the segments.
Claim 6
Dependent Claim
30 words
A curler as in claim 3 wherein said means at the ends of the curler comprises a resilient member elastically connecting the segments to allow radial movement inwardly and outwardly.
Claim 7
Dependent Claim
39 words
A curler as in claim 3 wherein said means at the ends of segments comprises members extending generally circularly between segments and constructed whereby to allow segments to move inwardly and outwardly radially with the spacing between segments changing.
Claim 8
Dependent Claim
30 words
A curler as in claim 6 wherein said means at the ends of segments comprises arcuate members extending from segments, adjacent segments having arcuate receptacles for slidingly receiving said members.
Claim 9
Dependent Claim
78 words
An expansible and retractable hair curler comprising a group of axial segments disposed about a central axis, the segments having an arcuate configuration, the segments normally forming a generally cylindrical hair curler, and means for holding the segments in position about the axis and for simultaneously moving them radially towards and away from the axis whereby to change the size of the curler, said means comprising an axially movable member having oppositely disposed linkages connected to axial segments.
Claim 10
Dependent Claim
78 words
An expansible and retractable hair curler comprising a group of axial segments disposed about a central axis, the segments having an arcuate configuration, the segments normally forming a generally cylindrical hair curler, and means for holding the segments in position about the axis and for simultaneously moving them radially towards and away from the axis whereby to change the size of the curler, said means comprising an axially movable member having oppositely disposed linkages connected to axial segments.
Claim 11
Dependent Claim
37 words
A curler as in claim 8 having linkages connecting axially disposed members with arcuate segments wherein said linkages hold segments firmly in their outermost position by occupying a position normal to said segments and the central axis.
Claim 12
Dependent Claim
43 words
A curler as in claim 8 having a plurality of axially disposed parallel members at intervals normal to the central axis for holding arcuate segments in their radial movement and having a plurality of parallel linkages connecting said members to said arcuate segments.
