Definitions

  • the electrical curling tongs comprise a thermostat which is manually adjustable by a knob embedded in a recess provided in the tongs handle.
  • the handle recess includes indentations adapted to mesh with corresponding indentations provided at the periphery of a ring interposed between the knob and the recess for presetting the temperature range of the tongs.
  • the ring includes internal stops and the knob also comprises stop means so that, upon rotating the knob within the ring, the rotary motion of the knob controlling the heating temperature is limited.
  • thermostatic device of the type comprising a cylindrical heating portion in which is mounted a heating resistor element and on which are wound the.locks of hair, a handle extending in prolongation of the said heating portion and a tongue hinged on the apparatus and adapted to grip round the said heating portion, thus forming a clamp which holds the lock of hair wound.
  • the said screw comprises a threaded portion passing right through the said support provided to this. end with a tapped hole, one end of the said threaded portion bearing upon the stationary contact while the other end comprises a control knob advantageously embedded in the said handle.
  • a ring or the like is inserted between the control knob and the wall of the handle recess in which the said control knob is embedded, the said ring comprising on its periphery indentations, notches or the like meshing with corresponding indentations provided in the said recess, as well as two stops limiting the rotation of the saidscrew in the said ring, the latter enabling the user to previously set the temperature range of the apparatus.
  • the said insulation support is mounted on a plate which is at one end riveted with the bimetallic element on the member forming a thermal bridge, and at the other end assembled with the stationary and movable contacts by means of a rivet passing right through the said insulating support at the level of the aforesaid fixed point.
  • the various thus imbricated members constituting the thermostat therefore form a compact assembly which may readily be placed within the handle or two half-shells forming this handle.
  • FIG. 1 shows a longitudinal sectional view of a curling iron according to the invention
  • FIG. 2 is an exploded view showing details of the manually adjustable control knob.
  • a screw 17 also passes through the insulating support 5 which is provided to this end with a tapped hole 18. The end 19 of the said screw abuts against the stationary contact 10.
  • the screw 17 is controlled by means of a control knob 20 embedded in a recess 24 of the handle 2.
  • a crown, ring or the like 21 provided at its periphery with indentations 22 is interposed between the knob 20 and the wall of the recess 24 in which the said knob is embedded.
  • the indentations 22 mesh with corresponding indentations 25 machined in the handle 2.
  • the crown or ring 21 also comprises two internal stops 23 limiting the rotary travel of the knob 20 which is also provided with corresponding stops 26, and therefore the rotary travel of the screw 17.
  • the improvements according to the invention comprise a ring or the like 32 preferably made from injected thermoplastic material and used to assemble the two shells forming the handle 2, rearwardly of the iron as clearly shown in the drawing.
  • the said ring may have any shape and size and may be made from any suitable material provided effective clamping of said half-shells is obtained.
  • thermostatic assembly just described is very simple/The position of the crown 21 is suitably adjusted.
  • This adjustment may be performed for instance during the manufacture of the apparatus.
  • the invention is by no means limited to the form of embodiment described and illustrated which has been given by way of example only.
  • the aforesaid printed circuit may comprise all necessary elements enabling the mounting of a voltage-varying device, such as a double-voltage device.
  • the invention therefore comprises all the means constituting technical equivalents to the means described as well as their combinations, should the latter be carried out according to the spirit of the invention and within the scope of the appended claims.
  • Electrical curling tongs comprising: a heating cylindrical portion around which locks of hair are to be wound; a resistor unit mounted inside said cylindrical portion; a handle extending said cylindrical portion; a hingedly mounted tongue capable of closely fitting said cylindrical portion and forming a gripper for holding the hair; an adjustable thermostat mounted in said handle and including a bimetallic member and a set of stationary and movable contacts; insulating support means having said thermostat secured thereon; plate means upon which said insulating support means rest; first rivet means securing said set of stationary and movable contacts and said plate means to said insulating support means; thermal bridge means interposed between said heating portion and said thermostat; second rivet means securing said thermal bridge means and said bimetallic member to said plate means; insulative pin means freely sliding in said insulating support means, said pin means having two ends for resting respectively upon said bimetallic member and said movable contact; electrical connection means including two contact prongs extending outwardly of said handle; printed circuit means mounted inside the handle between said two prongs and said thermostat
  • said handle includes two shell-halves and a clamping ring mounted at the outer end of said handle for firmly maintaining said two shell halves together.
