Abstract
Abstract There is provided a telescoping hand-held hair curler in which a heatable barrel slides longitudinally with respect to a hollow handle. The electrical wires carrying power to heat the barrel enter the rearward end of the handle and connect to a swivel coupling which reciprocates within the handle. The barrel extends forwardly from the swivel coupling and out through the other end of the handle. The construction avoids having loose wires running between a stationary swivel coupling and a moving barrel.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
147 words
A hand-held hair curler comprising: an elongated housing defining an internal elongated slide chamber with a barrel opening in one end and a wire opening in the other end, an electrical swivel coupling including a non-rotary portion adapted to reciprocate in said slide chamber but being restrained against rotation with respect to said housing, and a swivelling portion adapted to rotate with respect to said non-rotary portion, but being restrained against longitudinal movement with respect to said non-rotary portion, said swivelling portion including an electrical wire, whereby the wire can swivel with respect to the housing and can reciprocate along said housing as said non-rotary portion reciprocates, the wire extending out through said wire opening and being slidable therein, and hair-heating means connected to said non-rotary portion and projecting therefrom remote from said wire, the hair-heating means including a barrel which can project through said barrel opening.
Claim 2
Dependent Claim
147 words
A hand-held hair curler comprising: an elongated housing defining an internal elongated slide chamber with a barrel opening in one end and a wire opening in the other end, an electrical swivel coupling including a non-rotary portion adapted to reciprocate in said slide chamber but being restrained against rotation with respect to said housing, and a swivelling portion adapted to rotate with respect to said non-rotary portion, but being restrained against longitudinal movement with respect to said non-rotary portion, said swivelling portion including an electrical wire, whereby the wire can swivel with respect to the housing and can reciprocate along said housing as said non-rotary portion reciprocates, the wire extending out through said wire opening and being slidable therein, and hair-heating means connected to said non-rotary portion and projecting therefrom remote from said wire, the hair-heating means including a barrel which can project through said barrel opening.
Claim 3
Dependent Claim
25 words
The invention claimed in claim 1, in which the elongated slide chamber is of constant non-circular cross-section, the non-rotary portion being complementary to said cross-section.
Claim 4
Dependent Claim
21 words
The invention claimed in claim 2, in which the chamber cross-section is in the main circular but has two antipodal projections.
Claim 5
Dependent Claim
44 words
The invention claimed in claim 1, in which the hair-heating means includes a swivel clamp pivoted with respect to the barrel close to the swivel coupling and having a free end lying along the barrel, and means for biasing the clamp against the barrel.
Claim 6
Dependent Claim
56 words
The invention claimed in claim 4, in which a depressable trigger is provided on said housing adjacent the end through which said barrel projects, the trigger being positioned so as, when depressed, to urge inwardly against a part of said clamp adjacent the pivot therefor, thereby to move the said free end away from said barrel.
