Definitions

  • the hair-curlers are most often heated by means of sleeves in the form of pincers which are pre-heated and then applied to the rolled hair.
  • the heating rollers often consist of a cylindrical body split along a generatrix and provided with two extensions spaced on either side of the portion diametrically opposed to the split and forming a hinge, the said extensions forming organs for opening the pincer formed by the split sleeve.
  • the sleeves may be heated by placing them in contact with heating bars.
  • the hair-dresser has available a series of sleeves which are being heated and must take them one by one for application to the haircurlers.
  • the sleeves are made of a suitably shaped rubber or plastics mass.
  • the sleeves used until the present time in particular have wing-shaped extensions whose ends have concave faces to make it easier for the operator to take hold of them.
  • the fingers of the operator are thus in contact with a relatively large area of the sleeve.
  • the sleeve may attain a temperature of the order of 100 on the heater bars.
  • the heat thus developed over the internal face of the sleeve spreads relatively well in the rubber mass and it will be appreciated that it is necessary to protect the operators fingers.
  • the operator is therefore obliged to wear gloves or to grip the sleeve with insulating pincers.
  • the invention has as its object improvements to heating sleeves enabling these disadvantages to be remedied by means of simple and effective arrangements.
  • the cylindrical body is provided on its exterior wall with a plurality of longitudinal vanes arranged in planes extending radially about the axis of the cylindrical body.
  • the extensions forming opening organs of the pincer have in cross section the form of horns forming an acute angle at their bases with the axial plane of symmetry of the sleeve and then curving towards the split until, at their points, they form an obtuse angle with the said plane.
  • the sleeve formed of a mass of relatively flexible material such as rubber, comprises a cylindrical body 1 split along a generatrix 2.
  • the portion diametrically opposed to the split is reduced in thickness to facilitate 2 separation ofthe two sides of the cylindrical body by means of two extensions 4 which diverge on either side of the axial plane passing through the split 2 and form organs for gripping the sleeve, bringing together of which determines the opening of the pincer formed by the split cylindrical body.
  • the ends of the extensions 4 are tapered into points and curved towards the split until they form an obtuse angle A with the plane of symmetry of the sleeve, so that the points are substantially perpendicular to the said plane when the sleeve is open.
  • the point effect the quantity of heat transmitted to the fingers of the operator will be minimized.
  • the operator also has to touch the exterior wall of the cylindrical body.
  • the sleeve is provided along its exterior wall with a plurality of vanes 10 directed in planes extending radially about the axis x-x of the sleeve.
  • the majority of the vanes 10 is substantially normal to the wall of the cylindrical body and is therefore positioned in planes passing through the axis x-x'.
  • the vanes 11 closest to the extensions 4 are inclined towards the points of the said extensions. As a result, the operators fingers are prevented from contacting the concave portions of the extensions.
  • the length of the latter is increased by giving them the shape of curved horns, the bases of which form an acute angle with the plane of symmetry of the sleeve and then turn, as observed, to form an obtuse angle with the same plane.
  • the extensions are slightly narrower in cross section at the base than in the central portion.
  • the quantity of heat transmitted in the body of the extensions is thus reduced, and the bulge obtained enables the lateral surface area of the sleeve to be in creased and the heat transmitted to be thus reduced.
  • the manufacture of the sleeve is particularly economical, for it can be carried out in one operation, e.g. by moulding or extrusion, due to the elimination of the flocking which was previously necessary. Lastly, maintenance of the sleeve presents no problem.
  • vanes positioned on the lateral wall of the sleeve prevent burning of the scalp if the sleeve is wrongly positioned.
  • a heating sleeve for hair curlers comprising an elongate cylindrical body forming a pincer, a split along a generatrix of said body, two extensions on said body spaced on either side of the portion of said body diametrically opposed to the split and forming a hinge,
  • a heating sleeve in accordance with claim 1 wherein the two vanes closest to the extensions are inclined towards the points of the said extensions, the other vanes being substantially normal to the wall of the cylindrical body.
