Abstract
A device suitable for use as a permanent wave rod and hair styling roller is disclosed that employs a tubular component as a permanent wave rod, the tubular component having a first end portion, a second end portion, and a mid-portion therebetween about which to wind a lock of hair in the process of hairdressing. The device includes a first annular flange attached to the first end portion and a second annular flange attached to the second end portion, each flange having a periphery with a plurality of facets. A connector arrangement is included for enabling connection of each one of the end portions to a corresponding end portion of a similar device so that a facet on each one of the annular flanges bears against a facet on the similar device to inhibit rotation and unwinding of hair, without producing kinks in the hair.
Claims16
A device for use in hairdressing comprising:
- a tubular component having a first end portion, a second end portion, and a mid-portion therebetween about which to wind a lock of hair in the process of hairdressing;
- a first enlarged portion at the first end portion and a second enlarged portion at the second end portion, each enlarged portion having a periphery formed of a plurality of a small number of facets and being polygonal in cross section, each one of said facets having a substantial flat surface area contiguous to like facets on either side thereof to define a discrete radial angle for engaging a like facet of a similar device and help support said similar device at a desired distance away from the scalp of a person whose hair is being dressed;
- a pair of first and second end members at respective ones of the first and second end portions in positions extending axially outward therefrom;
- and
- connection means including first and second projection on each one of the respective first and second end members for enabling each one of the end portions to be connected to a corresponding end portion of a similar tubular component by interconnecting corresponding end members to cause a single selected facet on one device to bear against a single selected facet on a similar tubular component over a substantial surface areas of interengagement to inhibit relative axial rotation, and for enabling a pair of the devices to be positioned relative to one another for arranging the hair in a desired configuration.

A method of hairdressing, comprising:
- using a plurality of devices:
- each device comprising a tubular component having a first end portion, a second end portion, and a mid-portion therebetween about which to wind a lock of hair in the processof hairdressing;
- a first annular flange attached to the first end portion and a second annular flange attached to the second end portion, each annular flange having a periphery with a plurality of facets;
- and connector means for enabling connection of each one of the end portions to a correspodning end portion of a similar device so that a facet on each one of the annular flanges bear against a facet on the similar device to inhibit rotation;
- arranging a first series of the devices in a first row extendng in a first common plane with selected locks of hair wound around the mid-portions and with the end portions interconnected with facets of adjacent devices engaging one another to inhibit axial rotation;
- arranging a second series of the devices similarly in a second row extending in a second common plane with other selected locks of hair wound around the mid-portions with facets of adjacent devices engaging one another to inhibit axial rotation;
- engaging corresponding facets of a device in the first row with a device in the second row:
- and
- interconnecting the end portins of said device in the first row with the end portion of said device in the second row at a desired angle between the rows.
