Definitions

  • the present invention relates to a pair of scissors intended in particular, although not exclusively, to the art of hairdressing for haircutting by a practitioner.
  • the ring of the branch receiving the thumb namely in principle the movable branch
  • the ring of the branch receiving the thumb comprises a mechanism which makes it possible to modify the relative position of the finger vis-à-vis of the articulation of the two branches of the pair of scissors at the same time by varying the relative distance of the ring with respect to this articulation and on its orientation relative to the cutting plane.
  • the other ring receiving the ring finger does not allow any particular adaptation of the position of the finger, which again has a drawback for optimal use of the device.
  • the present invention relates to an improved pair of scissors which overcomes this drawback, by further providing other remarkable advantages, in particular by facilitating its adaptation to any shape by the practitioner's hand, and also by allowing this adaptation to be modified on demand, in particular the relative orientation of the cutting plane with respect to the fingers, the setting of the ring finger on the corresponding branch, the relative position of the thumb on the other branch and finally the freedom of movement of this same thumb opposite the receiving ring.
  • a pair of scissors according to the invention comprising two elements articulated around a common axis, each of which comprises a cutting blade extended beyond the axis of articulation by a branch provided with a ring allowing control of the branch by the end of a user's finger, one of the rings receiving the ring finger and the other the thumb of the user, is characterized in that one of said branches comprises, mounted in its ring, a transverse end piece in the form of a cylindrical tube, closed at one end and open at l 'other, said tip having in its outer surface a thread suitable for cooperating with a thread of the same pitch formed in the ring so as to adjust on demand the relative position of the ring relative to the tip which receives and immobilizes the end phalanxes of the user's ring finger.
  • the invention thus makes it possible to immobilize the ring finger holding the branch of the scissors, usually stationary, in a safe and convenient manner, in particular facilitating the adaptation of the end piece to the shape and anatomy of the finger which penetrates therein.
  • the tip can be adjusted in the ring in the best position according to the size of the ring finger, its length, its thickness ...
  • the tip can receive by its open end, a slipper protection of the ring finger, especially if the user is female.
  • the scissors comprise in each of the two branches extending the blades, an adjustable connection between the branch and the ring, capable of modifying, on request, the inclination of this ring with respect to the blade cutting plane.
  • This arrangement also makes it possible to make the blades interchangeable.
  • the ring has an extension provided with a stud engaged by force in a housing provided at the end of the associated branch.
  • locking means make it possible to secure the branch and the extension of the ring once the relative orientation of these two parts has been adjusted.
  • These means may consist of a ball pawl or nestable notches, or any other mechanically equivalent locking solution.
  • the receiving ring can thus be axially offset by improving once again the relative position of the fingers with respect to the blades, with greater efficiency combined with convenience. '' greatly increased use, in particular by avoiding excessive flexion of the wrist.
  • the ring receiving the thumb is mounted movable longitudinally in a groove of the corresponding branch to allow the position of this ring to be modified relative to that of the other ring carrying the end piece receiving the ring finger.
  • the ring comprises a guide lug engaged in the groove, a return spring being mounted between the lug and a lateral stop in the groove, to facilitate movement and immobilization of the ring by notches blocking staggered along the length of the groove, or by a slider that can be moved parallel to it.
  • the ring receiving the thumb is open laterally to facilitate the possible escape of the thumb, in particular when for the pulling of the locks, the user uses the thumb, the medium and the index finger, the scissors remaining held by the only ring finger.
  • the pair of scissors generally designated by the reference 1, conventionally comprises two blades respectively 2 and 3, each extended by an operating branch 4 or 5, beyond a joint common 6.
  • the pair of scissors considered is more particularly intended for the use of a hairdressing practitioner for cutting a client's hair.
  • the pair of scissors considered is more particularly intended for the use of a hairdressing practitioner for cutting a client's hair.
  • it is held by the user's hand between the ring finger 7 of the latter and the end of his thumb 8, each of these fingers being respectively engaged in a ring 9 for the annular, provided at the end of the branch 4 and in a ring 10 for the thumb, provided at the end of the branch 5.
  • the rings 9 and 10 are schematically shown provided with improvements according to the invention, consisting in particular in the establishment in the ring 9 of an adjustable tip 11 in which the phalanx engages end of the ring finger 7, the branch 5 being arranged so that the ring 10 receiving the thumb 8 is adjustable in position along this branch, at the same time as it allows a lateral escape of this thumb, necessary for the accomplishment of certain phases in the haircut.
  • the rings 9 and 10 each have an extension respectively 12 and 13, the connection with the associated branches 4 and 5 is effected by means of a connecting element 14 allowing, in the manner which will be explained below, an offset relative to the plane each containing rings 9 and 10 with respect to the associated branch.
  • Figure 2 shows schematically how the previous arrangements allow on the one hand a better immobilization of the ring finger 7 in the end piece 11 carried by the ring 9 and on the other hand a relative orientation, variable at the discretion of 'the user between the cutting plane 15 in which the blades 2 and 3 struggle and the planes 16 and 17 of the rings 9 and 10, the angles respectively a and b formed between these planes can be equal or different depending on the morphology of the hand and the corresponding positions taken by the ring finger and the thumb.
  • Figure 3 illustrates on a larger scale the embodiment of the end piece 11 mounted in the ring 9 to receive and immobilize the ring finger 7.
  • This end piece essentially consists of a tubular element 18 open at one of its ends 19 through which the ring finger enters, the opposite end 20 being closed.
  • the end piece has a thread 21 allowing it to be positioned in a thread 22 formed in the internal surface of the ring 9, thereby allowing, depending on whether the end piece is more or less screwed into the ring , to adjust its transverse position relative to it, in particular according to the length of the end phalanx of the ring finger entering the end piece.
  • the bottom 20 of 1 tip advantageously has a groove 23 facilitating the relative rotation of the tip in the ring.
  • slots 24 are usefully provided in the lateral surface of this endpiece, giving it a certain radial flexibility so that, once it is in place, these slots achieve suitable self-locking of the endpiece on the ring.
  • the user can directly engage the ring finger in the tip or use a kind of flexible liner 25 previously engaged on the phalanx of the finger before it is engaged in the tip.
  • a kind of flexible liner 25 previously engaged on the phalanx of the finger before it is engaged in the tip.
  • one can provide in this liner an extension 26 to wrap and protect the nail of this phalanx.
  • FIGS. 5 and 6 illustrate two alternative embodiments of the connection device 14 making it possible in particular to ensure the connection between the branches, for example the branch 4, of the pair of scissors 1 and the extension, for example 12, which is attached to it associated in extension of the corresponding ring.
  • the extension 12 comprises an axial stud 27 adapted to enter a housing 28 provided in the branch 4, the stud and the housing having complementary shapes preferably slightly conical.
  • the lug 27 furthermore has a lateral groove 29 open towards the outside and into which a locking element can be snapped in, comprising in particular a ball 30 subjected to the action of a spring 31 mounted in a recess 32 and immobilized by a closing plate 33.
  • the extension 12 again includes a stud 27 suitable for engaging in a housing 28 of the branch 4 in this variant, however, once the relative orientation of the two parts chosen, those these are locked in position thanks to the cooperation of notches 34 and 35 arranged opposite one and the other.
  • FIG. 7 illustrates another improvement of the pair of scissors considered, making it possible in particular to ensure the longitudinal displacement of the ring 10 receiving the end of the thumb of the user according to the lo extension extension 13 extending branch 5.
  • the extension 13 has a hollow groove 36 provided with two opposite slots 37 and 38 respectively.
  • the ring 10 is provided with a lug 39 penetrating through the slot 37 in the groove 36 in sliding in the latter to vary its position relative to the extension 13.
  • a spring 40 is advantageously mounted between the lug 39 and a plug 41 forming an end stop closing the hollow groove 36.
  • a transverse pin 42 allows 'immobilize the plug on the extension.
