Definitions

  • This invention is directed to a hair plucking mechanism, and in particular a string tensioning and twisting mechanism for use in entraining and plucking hair.
  • the many methods that have been practiced include: - shaving or scraping, in the manner widely practiced by men, using blade razors, electric shavers, and equivalents; - waxing, using a coherent wax layer to which the hair adheres; - chemical depilation, using a chemical which attacks the hair; - tweezers, seizing individual hairs for manual extraction; - electrolysis, using an electrically charged needle to kill the hair roots, individually; and -stringing, wherein a hand held string is rotated by an entrained portion of the string, held by a skilled operator to entrap and extract the hair.
  • Shaving is fast, convenient and generalized, but is believed by many to promote rapid growth, and hair coarsening.
  • Chemical depilation is convenient, but presents certain dangers to sensitive skins, and may be unpleasantly odiferous.
  • Tweezers are extremely effective, but very slow, tiresome and can be quite painful and nerve wracking.
  • Electrolysis requires a skilled operator and special apparatus. It is effective, but expensive and time consuming.
  • Stringing requires the services of a second person, skilled in manipulating the strings (a "Haffafa” in Arabic). After stringing, the rate of hair growth is slow, as the root usually has also been pulled; and the regrown hairs tend to become progressively finer with successive stringings.
  • manual manipulation of a "string” requires the use of both hands and the mouth of the Haffafa; and virtually precludes self administration except in the simplest instances.
  • the present invention provides a string manipulating mechanism whereby the removal of hair by string entrainment can be practiced by an unskilled person, and by the user on their own body.
  • the present invention provides a string manipulating mechanism for pulling body hair from a subject, the mechanism comprising a body portion; first string support means for extending a first run of string; second string support means for extending a second run of string; a first string positioned by the first string support means; a second string having a portion thereof in coiled relation about a portion of the first string and positioned by the second string support means; and driving means for producing relative movement between the strings to cause travel of the coiled portion of the second string, in use to entrain hairs of a subject in trapped relation therewith.
  • a string manipulating mechanism for pulling hair from a subject, the mechanism comprising a body portion, stretcher means extending therefrom having a pair of spaced first end portions for the suspension of a first string therebetween; oscillator means supported by the body portion having a pair of spaced apart second end portions for the attachment of a second string thereto; a first string of predetermined thickness suspended between the first end portions; a second string having a portion intermediate the ends thereof wound by way of a plurality of turns about a central portion of the first string and connected by intervening end portions to the oscillator means second end portions in tensioned relation; and means for oscillating the oscillator means so as to successively increase and decrease the respective lengths of the second string intervening end portions and correspondingly advance and retract the turns of the second string along the first string in twist-inducing relation with the first string, in use to engage hairs of a subject in entrained relation therewith, to further roll up the hair to the point of extraction, and to discard the thus extracted hair.
  • the first string may be directly tensioned or tensioned by the second string.
  • the fineness of the strings is usually selected with regard to the coarseness of hair to be dealt with, coarser string being required for thicker, stronger hair.
  • the subject mechanism is effective in the removal of hair.
  • the mechanism is self cleaning, at least in the case of normal length hairs, which are sequentially discended as a consequence of the continually reversing movements of the two strings.
  • the subject apparatus is suitable for manufacture in a number of alternative embodiments.
  • One embodiment comprises a portable, hand-held trigger operated apparatus, of simple low cost components.
  • Another embodiment incorporates an electric motor characterized by low power requirements, suitable for use with batteries, including the rechargeable type.
  • the mechanized versions have been found to function effectively with an output speed of about 60 to 120 revolutions per minute, to produce a corresponding rate of string oscillation.
  • the arrangement 10 shows schematically how a single string 12 is used by a Haffafa, having one end 14 held in the teeth, the other end 16 held by one hand (illustrated as being the left hand, but not imperatively so) the bight 18 passing about the thumb of the other (right) hand, and the bight 20 passing about the first and second fingers of the other right hand.
  • the string is coiled about itself, and provides a coiled region 22.
  • the Haffafa opens and closes the involved fingers and thumb of the right hand in movements that are synchronized with back-and-forth movements of the head. This causes the coils of the string to oscillate leftwardly in response to a backward, tensioning head motion and a simultaneous forward releasing motion of the thumb. Reversal of the thumb and head motion, while maintaining the string under tension, rotates the coils so as to travel rightwardly.
  • the string With rhythmic repetitions, the string gives an impression of becoming elastic, due to the smoothness of the to and fro oscillations, at which time the intertwined string portion is brought into contact with, and swept across, the skin of the subject being treated.
  • This entrains, plucks and discards hairs traversed by the intertwined string, by the action of the intertwining string coils catching and rolling the hair (entrainment), retaining engagement of the hair so as to pull it from the skin (plucking), and then freeing the pulled hair from the string coil as it either passes by that portion of the string where the hair is caught or by reversal of the string coil oscillatory motion (discarding).
  • the arrangement 20 comprises a U-­shaped frame 22 having a handle 24 extending therefrom; and a trigger 26 pivotted at 28, having a return spring 29.
  • a beam portion 30 extending from the frame 22 connects with a pair of bifurcated legs 32 that constitute a stretcher means.
  • a first string 33 tensioned by spring 35 extends between attachment apertures 37 of the stretcher means.
  • a second string 34 has coils 36 thereof wound about string 33 in entwined relation therewith. Intervening end portions 38, 40 of the string 34 are secured to an oscillator means 42.
  • the oscillator means 42 comprises a bar 43 pivotably mounted at 44 to a portion 23 of the frame 22.
  • bar 43 comprise second end portions 45, 47 having apertures 49, 51 to which the respective string portions 38, 40 are secured.
  • a link 50 extends in substantially rigid interconnecting relation between spring loaded trigger 26 and oscillator bar 43.
  • the ends of link 50 are respectively pivotably connected at 52 to the bar 43; and at 54 to the trigger 26.
  • the flat biassing spring 29 secured to handle 24 depresses the trigger 26 in forward pressing relation, to extend link 50 forwardly, whereby the string end portion 40 is diminished and the string end portion 38 is extended.
  • the handle 24 is gripped by a user's hand, the trigger 26 being encircled by the index finger, for repeated pulling and releasing of the trigger 26.
  • the length of string portion 38 increases by pulling turns off the coils 36.
  • the string portion 40 shortens as it is pulled in coiling relation to replace the coils 36. Consequently the coils 36 move leftwardly, simultaneously twisting the first string 33.
  • the string interaction zone comprising the coils 36, traverses to and fro along a portion of the length of the first string 33, while simultaneously twisting and reverse twisting that string.
  • FIG. 3 there is illustrated a U-frame 60, the resilient legs 62, 64 of which serve to tension the first string 66.
  • a pair of plates 68 having apertures 69 receive the ends of string 66.
  • An arm 70 from which the frame 60 is suspended has a downwardly depending pivot pin 72 on which is mounted a rocker arm 74 in pivotal relation therewith.
  • the rocker arm 74 has end portions 75, 77 to which the ends 76, 78 of the second string 80 are secured.
  • crank shaft 84 produces oscillation of rocker arm 74 about its pivot pin 72, thus oscillating the second string 80 and correspondingly displacing the string interaction zone to and fro as indicated by the double headed arrow 86.
  • Figure 4 shows an alternative frame arrangement having a U-shaped frame 90, of which the leg 92 is used to attach the frame 90 to the body of the device (not shown).
  • the first string 95 is illustrated as being tensioned by the second string 93.
  • the string interaction zone 97 shown in a somewhat extended form, oscillates in time with the rocker arm 94, in the same fashion as before.
  • the frame embodiment 100 incorporates a resilient hoop 102 having a transverse frame member 104 with brackets 105 to which the first string 106 is attached.
  • a second transverse frame member 108 is used to attach the frame 100 to the body of the device (not shown), to which the rocker arm 110 also is pivotted at 112.
  • the rocker arm 110 has a driving slot 14 to receive a crank pin (not shown), in the manner of the Figure 3 embodiment.
  • Figure 6 shows a powered embodiment 120 having a body portion 122 containing a battery, a battery driven motor and a reduction gear connected in driving relation with a rocker arm 124 having laterally extending arms 126 to which the second string 128 is attached.
  • a frame 130 is adjustably attached at 132 to the body 122, by way of a clamp 134 and adjustable cap screws 136, which permit the frame 130 to be removed or adjusted.
  • the first string 137 is carried by the frame 130 in tensioned relation, by way of spring 138. Operation of the device 120 is controlled by switch 140.
  • the device 150 is powered by a power pack 152.
  • the battery 152 can be a rechargeable battery.
  • a casing 160 shown in partial section contains an electric motor 162, the output gear 164 of which is connected in driving relation with a multi-stage reduction gear 166.
  • the simple, multi-stage reduction gear 166 provides a low output torque at about 60 to 120 r.p.m. to the crankshaft 170, driving a circular cam 171 as illustrated in Figure 7 to oscillate the rocker arm 172 and second string 174.
  • the rocker arm 172 is also shown in phantom in Figure 7 at its two limiting positions.
  • buttons 165 each comprise a pair of opposed resilient circular discs forming a V-­groove therebetween into which the respective strings are shown, in wedged secured engagement therein.
  • alternative methods such as knotting are also effective.
