Definitions

  • the present invention relates to a tweezers with tear-off pliers which can be held by hand and intended to remove unwanted hair from the human body.
  • This type of depilatory device generally comprises blades in the form of blades or discs arranged on a rotating roller, the clamps being caused to close and open periodically so as to tighten the hairs close to the skin to tear them off. by the rotation of the roller and, respectively, to evacuate the torn hairs.
  • apparatus comprising a housing adapted to be held by hand and containing a drive motor for a roller movable in rotation about a central shaft arranged behind a window in the housing.
  • the roll has a plurality of rows of clamps, each row being formed of a first series of movable side-by-side parallel blades interposed between a second series of also movable blades, the pinch edges of the blades being bent axially with respect to the bases. blades.
  • the first series of blades is secured to a central player, the second series of blades is secured to a cage surrounding the walkman coaxially.
  • the apparatus further comprises cams arranged laterally on the flanges of the roller, said cams applying to the walkman and the cage reciprocating translational movements and in opposite directions.
  • this device is quite complex construction and assembly, the assembly of the blades being alternately in the grooves of the central shaft and those of the peripheral rods.
  • all the clamps of a row are operated simultaneously, which implies a large power of the engine simultaneously actuating the series of clamps, power which, in addition varies a lot in time, between a maximum value corresponding to the actuation of the clamps and a minimum value when they are no longer actuated. This requires a powerful engine, expensive and bulky and whose life is reduced.
  • the clamps are constituted by rods of cylindrical shape, split radially and supported along the periphery of a cylinder driven in rotation being parallel to the axis of the cylinder.
  • the clamps pass successively in front of the epilation window of the housing, their ends coming into contact with cams supported by the side walls of the housing. This produces the axial displacement in opposite directions of their ends and, consequently, the closure of the clamp.
  • Such a device poses particular problems as to the shape of the forceps which in this case have a large contact surface with the skin during epilation, they rub on the skin, which can produce irritations that can cause pain sensations. on the skin of the user. In addition, these friction impose an additional constraint to the actuating motor of the apparatus.
  • a pinch module has four movable blades alternating with four fixed blades mounted on a common plate, the ends of the movable blades passing through holes of this plate to be inserted in groups of two in the slots of two actuating rods.
  • the actuating rods are parallel to the axis of the cylinder. Two adjacent mobile blades are thus displaced by a first actuating rod, engaging with a cam supported by one of the side flanges of the housing, the other two being displaced by a second actuating rod, located in the extension.
  • the main drawbacks of this document are related to the large number of individual components making their operation complex and the assembly of all these components together. Furthermore, the arrangement of the movable blades in series within the same operating lever makes the clamping force strongly depends on the stack of blades on each of the levers, whose intervals must be strictly equal to each other. In addition, a series arrangement of the blades involves a large longitudinal dimension of the rotating cylinder.
  • the object of the invention is to remedy, at least in part, the above-mentioned drawbacks and to propose a pull-apart epilator device of compact construction, able to operate with a motor of lower power, while being reliable in operation .
  • Another object of the invention is a tweezers device with pliers able to ensure proper pinching of the hair and therefore a constant quality of hair removal throughout its life cycle.
  • Another object of the invention is a device with pliers for tearing able to reduce the pain felt during tearing, to reduce the noise of operation, while being of simplified construction and allowing its realization in large numbers at reduced cost .
  • a depilatory apparatus comprising a housing adapted to be held in the hand and containing an electric motor driving a rotating roller around a central shaft, the roller having one or more rows clamps, each clamp being formed of two blades arranged side by side in the longitudinal direction of the shaft of which at least one is a movable blade, control means which print said blades an alternating translational movement one to the other, the blades of two consecutive rows being angularly offset on the periphery of the rotary roller, because two movable blades are connected at their base by a spacer forming together a moving monobloc part, at least two mounted monoblock mounted parts in parallel are part of the same row of the rotating roller being partially offset longitudinally relative to each other.
  • a tweezer already has a hand-held housing and a rotating multi-row rotating pliers roll that rotates relative to the housing to pull hair out of the human body.
  • a row of pliers comprises a group of pliers which are arranged in the same area of the rotating roller and which simultaneously receive the same closing or opening movement of the control means.
  • the movable blades are grouped in two and are interconnected by their base thus forming a moving monoblock part, the movement of this moving part being then printed at the same time to each of the two blades.
  • Such a construction can easily be made based on a metal sheet by cutting and folding operations using a single tool, thereby obtaining good accuracy for each group of two blades.
  • Two mobile blades subsequently benefit from a common actuating means, which greatly simplifies their assembly.
  • Two moving piece pieces thus obtained are mounted in parallel in the frame of the same row of the rotating roller being partially offset longitudinally. It will be understood that the two spacers of the moving one-piece parts overlap for part of their length. The actuation in translation of one of the moving one-piece parts induces a parallel displacement of a moving part relative to the other. It is understood that the movable blades must have a sufficiently large width, in particular greater than the width of their respective spacer, especially when the two monobloc pieces are moving along two parallel axes.
  • the parallel assembly of two moving one-piece parts and thus of four movable blades makes it possible to reduce the space requirement in the longitudinal direction of the shaft and consequently to produce a rotating roll shorter and easier to handle.
  • the blades of two consecutive or adjacent rows are angularly offset on the periphery of the rotating roller so as to allow closure of the pinches offset in time, during the rotation of the rotating roller, in order to tear the bristles from the surface. of skin treated by the rotating roller in a manner offset in time and to reduce the pain felt during tearing.
  • two moving one-piece pieces are driven in a translation movement along a common median axis.
  • common median axis includes a longitudinal axis passing through the center of the movable blades.
  • Two moving one-piece pieces thus have a width restriction on the part where the two spacers overlap longitudinally.
  • said moving one-piece pieces are slidably supported at the periphery of the rotary roller.
  • said movable blades come into contact each with a adjacent support blade during their reciprocating movement.
  • a support blade which is generally a fixed blade (it includes a blade which is not actuated by the control means), between the movable blades to thereby increase the number of clamps per row and therefore the efficiency of hair removal, for a simplified construction.
  • two support blades together form a one-piece support piece being connected at their base by a spacer, at least one of the support blades being located between two movable blades.
  • the bearing blades are also grouped in pairs and are interconnected by their base forming a single piece. Such a construction can easily be made based on a metal sheet by cutting and folding operations using a single tool, thus obtaining good accuracy for each group of two blades. Two bearing blades subsequently benefit from a common fastening means, which also simplifies their assembly.
  • a one-piece support piece is between two movable blades of two adjacent moving one-piece parts.
  • said one-piece support piece is mounted free in translation relative to an adjacent movable monobloc part.
  • a one-piece support piece is generally a fixed part.
  • such a one-piece support piece may have a degree of displacement in translation to better distribute the clamping forces during the closure of the clamps. Mounting constraints are also avoided.

  • peripheral groove cam has significant advantages in terms of constructive simplification, as well as in terms of noise attenuation, the blades being guided in the groove of said cam when moving around the groove. central shaft of the roller.
  • At least two grooves of said cam comprise bent zones oriented in opposite directions with respect to each other.
  • Each movable monoblock piece is actuated individually by following one of the grooves of the cam. Two moving one-piece pieces that follow two inversely inclined grooves will then be driven in axial movements in opposite directions. This makes it possible to better balance the forces within the rotary roller, two adjacent fixed blades receiving forces in the opposite direction.
  • the movements applied to the two one-piece pieces movable by said control means being reciprocating movements in the opposite direction, the translation travel is divided into two half-races carried out directly by each moving monoblock piece. This allows the use of a less deep cam device, so more reliable in time and less cumbersome.
  • each groove controls two diametrically opposed tearout modules and said cam has a plurality of grooves offset longitudinally.
  • Two pulling modules are arranged at 180 ° relative to each other in the same groove of cam, so that the movements of their tongs are also angularly offset during the rotation of the roller, for example one has the clamps closed while the clamps of the other are open. This makes it possible to control two modules at a time with the same cam groove.
  • cam grooves are offset longitudinally according to the longitudinal offset of the clamps of the various modules.
  • the apparatus of the invention comprises two movable closing cams slidably mounted against a spring in notches inside the shaft having grooves which are in line with the grooves formed on the groove. the tree.
  • This solution makes it possible to dispose said cam within the central shaft itself, where the cam and the shaft have grooves on their periphery, the grooved part of the shaft thus forming a fixed cam.
  • This makes it possible to obtain a remarkable compactness in the radial direction of the rotating roller and, subsequently, a hair removal head apparatus of small diameter, which is small in size and can rotate at a higher speed, which guarantees more efficiency from the first pass of the device on the skin.
  • Said spring is intended to compensate for assembly manufacturing play and wear in operation and it acts only on the movable closing cam, so that the elastic load is applied only at the time of closure of the clamps, which reduces the engine consumption and allows the use of a reduced power engine.

  • the first module 2.1 shown in the 0 ° position is in the maximum open position; the next module 2.2 is him in pinch position where the blades were quickly closed by the control means; the modules 2.3 and 2.4 have the clamps also closed to perform the tearing of the hairs gripped by the blades; the modules 2.5 and 2.6 have them open forceps in order to evacuate the torn hairs.
  • the electric motor rotates the toothed gears of the toothed rings of the flanges 4,5 driving the pulling modules 2 around the control shaft 40.
  • the movable blades 20 then perform a translation movement along the longitudinal axis of the rotary roller 1, sliding in the rails 14,15 of the sectors 9 of the cage 10, they deviate or approach the adjacent bearing blades 21 according to the position of the lug 22 of each movable blade 20 in one of the grooves 30,30 'of the shaft 7 or in one of the grooves 35,35' of the cams 34,34 '.
  • the lugs 22 paces the grooves 35,35 'of the closing cams 34,34' against the force exerted by the springs 37,37 'on the movable cam 34 and push the blades movable 20 to the adjacent support blades 21, the closing of a clamp is also realized against the force due to the elasticity of the movable blades 20 and supports 21 in contact.
  • the springs 37,37 'of the movable cams 34,34' and the elasticity of the blades 20,21 are calculated so that a constant force is exerted on the bristles at the time of closure of the clamps.
  • the bristles gripped by the tongs are then torn off during rotation of the roll and discharged outside the apparatus.
  • the rotary roller 1 may comprise a greater or lesser number of tear modules 2, the number of modules increasing with the diameter of the rotary roller.
  • a rotating roll 1 having a diameter of about 19 mm can accommodate six pull-out modules, while for a diameter of about 23 mm, eight can be provided.
  • the grooves of the cams are greased in order to reduce the friction of the pins on the walls of the latter.
  • a rotary roller comprising a one-piece shaft, without having a moving cam, and fixedly mounted relative to the housing.
  • This one-piece shaft would then be provided with grooves along its entire circumference, the movable blades then being mounted normally closed against the return springs with respect to one another, the spring of the cams then being able to compensate the wear of the flanks of the grooves of the cams.
  • the movable blades may be fixedly mounted in their position remote from the adjacent fixed blades which, they could then become mobile by being actuated at their base to perform the translational movement and come to apply alternately against a blade adjacent mobile.
