Definitions

  • the invention relates to motorized epilation apparatus for remo ⁇ ving superflous skin hair, and more particularly, to a new and u- seful device having novel rotary heads conformed by elements of straigth cylindrical shape of multiple adjacent sections forming annular gaps, disposed in lineal axis of rotation.
  • a new and u- seful device having novel rotary heads conformed by elements of straigth cylindrical shape of multiple adjacent sections forming annular gaps, disposed in lineal axis of rotation.
  • US Pat. 4.524-772 to Daar et al. discloses an arcuate spring pr vided of motorized rotational motion,
  • the spring comprises a plur ality of a ⁇ jacent windings arranged to define a convex side wher ⁇ eat the windings are spread apart and a concave side correspondi ⁇ ng thereto whereat the windings are pressed together.
  • the contact between the helical spring and individual hairs is point-like so that the ha ⁇ ir may be pinched and not plucked.
  • the rotational speed of the spring having an arcuate axis of rotation is limited and con- secuently depilation is slow and painful.
  • Another operational disadvantage is produced as the hairs are tr apped at distance of the skin about one half of the spring diame ⁇ ter, so that short hair escape and are not plucked.
  • Such advantages are especially procured by a novel method of re ⁇ moving superflous skin hair consistent of opening and closing plurality of periferial gaps on the outer surface of a straight cylindric element simultaneously driven at very high rotating speed.
  • Said method is practically achieved by various optional hair-plucker heads of elongated cylindrical shape, having multi ⁇ ple sections of flat planar side, that provide multiple adjacent annular gaps.
  • Said plucker head being of balanced weight andstraight axis of rotation,can be driven at very high rotational speed, resulting a fast, almost painless depilation and highly efficient.
  • the present invention consists essentially of three functional groups: the motor, reciprocating mechanism means and a hair plu ⁇ cker body means.
  • Said reciprocating means consist of a motion converter compris- ing two steps: the first converts rotation into an alternate an ⁇ gular motion and the second converts said angular motion into an alternate lineal motion.
  • the hair plucker body comprises essentially a longitudinal cyliri drical head of multiple sections provided of two ending terminals supported and rotated by a main shaft coupled to said motor.
  • the hair plucker body rotates and the reci ⁇ procating means output motion connected to it produces the open ⁇ ing and closing of a plurality of annular gaps in the outer sur- face of hair plucker head: during opening hair enter in the gaps and the following closing sizes it and simultaneous rotation plu cks it.
  • a rotary cylindrical hair plucker depilato ry device comprising in combination:
  • - rotary hair plucker body means connected to said housing and protruding from it comprising an exposed rototable hair plucker head formed by a cylindrical helicoidally coiled strip of thin rectangular cross-section width-wise normal to longitudinal a- xis of a main rotating shaft, having said head end supports fi ⁇ xed to said-main shaft at its outer end and connected to said re ciprocating means at its inner end, said hair plucker head havi ⁇ ng loops defining gaps therebetween which alternately open and close in accordance with said reciprocating motion provided by said reciprocating means and arranged to rotate synchronously, with said main shaft substantially parallel to an area of skin from which hair is to be removed.
  • a motor disposed in saidhousing and being arranged to rotate said hair plucker body means and synchronously feed motion to s_a id reciprocating means.
  • cylindrical rotary head depilatory design is provided as a hand-held, motor powered depilatory devi ce having a main rotating shaft that feed motion to hair plucker body and to reciprocating mechanism.
  • a fixed eccentricity cam is fastened on main shaft and on top of it an adjustable eccentrici ty cam, the two composing a crank shaft together with an Integra lly formed crank collar rod introduced in a bushing extreme end of a rock-shaft mounted on bearing and having in the other end a fixed bevel gear coupled to a similar gear fixed on a secondary rock-shaft.
  • a stop fixed on s_a id secondary rock-shaft engages an abutment fixed on one end of a free rotating twin bushing lever; in the opposite direction engagement is bounded by a check spring; both opposite ends of said twin lever are connected each to an articulated arm, both linked to a slide sleeve collar such that apply reciprocating mo_ tion to hair plucker body.
  • the outer end of hair plucker head is fixed to said main shaft, the inner end provided of said sliding sleeve foraxial reciprocation, is engaged for rotation by its in ternal grooves associated to axial projections of said main sha ⁇ ft.
  • a circumferential channel located at the end of said sliding sle eve mounts said collar provided of diametrally opposed pins ade- cuate for link of said articulated arms.
  • the hair plucker head can be made of any elastic or semielastic material, preferently of low friction plastic providing normally open or close loops, since, unlike prior art devices applying spring return cam follower, the present invention provides cam enforced reciprocating motion.
  • the hair plucker body provides a cylindrical bellows-like head of any elastic or semielastic ma ⁇ terial having either normally open or normally closed loops, pre ferently of low friction plastic, provided of a central extended borehole for passing through of main shaft and a plurality of ve ts on the sides of flat planar bellows sections to hinder shock absorber effect of air, opposite to reciprocating motion.
  • the hair plucker body compri ⁇ ses a cylindrical helicoidally coiled wire of any elastic or se- mielastic material having either normally open or normally clo ⁇ sed loops, said wire of any cross-section, preferently rectangu ⁇ lar, such as the hair is sized in multiple points, provided of an internal hair plucker head cage for hindering head deformati ⁇ on by centrifugal force at high speed.
  • anyone of the previously de3 cribed hair plucker head can be provided of a simple and economi cal feature substituting the need of said overcompression check spring applied in previous described reciprocating means.
  • the reciprocating means com prise a fixed eccentricity cam fastened to said main shaft, and on top of it an adjustable eccentricity cam of outer spherical profile associated with a spherical internal profile collar hav ⁇ ing a rod and a ball-joint connected to a swing-arm mounted on a perpendicular pivot, providing also free rotation axis to a fork lever, both having a common swinging plane lying on said main sh aft axis.
  • a stop fixed on said swing-arm engages an abutment fi ⁇ xed on an end of said ork lever in a turning direction, while in the opposite direction swing-arm and fork lever are bounded by a check spring adecuate for closing pressure control .of hair plucker loops; fork lever opposite end is connected to slide sleeve col ⁇ lar pins and applies said lineal reciprocating motion to said ha ir plucker head.
  • reciprocating means are desig ⁇ ned to reciprocate the hair plucker head from both end supports and in a particular form by two setsof screw and female-screw of opposite thread mounted in a rock-shaft that apply lineal recip e rocating motion alternately inward and outward the center of plu cker head, respectively closing and opening loop gaps.
  • This par- ticular feature offers the advantage of reducing transverse defl ection of hair, which would push shorter hairs out from between plucker head loops reducing efficiency.
  • the housing provided is sha- ped similarly to an electric shaver and though the operating pri nciple is identical to previous embodiments, the reciprocating motion is applied to both end supports of hair plucker head, ha ⁇ ving besides said overcompression auxiliary coils.
  • the electric motor mounted with its axis parallel to hair plucker head rotation axis, provides motion by belt transmission to a pu lley fixed on main shaft; internal grooves of hair plucker end supports, combined with projections of said main shaft transmit rotation to both hair plucker ends, keeping the capability to slide as said end supports receive reciprocating motion; said main shaft pulley provides on external-lateral side several ecce ⁇ ntric boreholes and introduced in one of said holes a right an ⁇ gle rod having the other end inserted in a bushing integrally fo rmed with a rock-shaft supported by bearing for swinging motion; variation of hair plucker gap aperture is produced by choice of said holes of different eccentricity.

Abstract

Dispositif d'épilation par rotation possédant une tête épileuse (9) montée saillante sur un boîtier portatif (1) et constituée d'une bande cylindrique enroulée de manière hélicoïdale sur un axe rotatif (5) et destinée à ouvrir et à fermer, pendant la rotation, une pluralité d'espaces annulaires afin de saisir et d'arracher les poils. Dans le mode préféré de réalisation, ledit dispositif d'épilation par rotation est constitué de trois ensembles fonctionnnels principaux, à savoir un moteur électrique miniaturisé (2), un corps épileur et un corps de mécanisme à mouvement alternatif. Le moteur entraîne le mécanisme à mouvement alternatif et l'axe rotatif, entraînant en rotation à vitesse élevée ladite tête épileuse. Le mécanisme à mouvement alternatif produit un mouvement de sortie altenatif et linéaire destiné à étirer et comprimer en alternance la tête épileuse de telle sorte qu'une pluralité d'espaces annulaires s'ouvrent sur la face externe de la tête puis se referment de manière à saisir un poil. Simultanément, la rotation arrache le poil et le relâche lorsque les espaces annulaires s'ouvrent de nouveau.
