FIELD OF APPLICATION

[0001] The present invention relates to a hair cutting tool, which in particular falls within the field of professional equipment for hair stylists.

[0002] Operationally, the cutting tool according to the invention is suitable for carrying out the textured hair cut technique.

[0003] Advantageously, such tool may be used not only for the textured cut but also for the bob hair cut and full shapes .

PRIOR ART

[0004] In their professional activity, hair stylists use many cutting tools and methods. The choice of a particular cutting tool is essentially linked to the type of cut to be made.

[0005] Common scissors, with two blades with a straight or toothed cutting edge, are the most traditional tool. Typically, in the use of scissors, the operator collects and tensions a lock of hair between two fingers, while with the other hand, holding the scissors, he/she makes the cut by closing the two blades. The cut of the lock will be clean and uniform or will affect only a part of the hair of the lock depending on whether the scissors have straight edges or with teeth.

[0006] The razor is another tool widely used by hair stylists. Typically, the razor has a single blade, with a much sharper edge than that of scissors.

[0007] Operationally, the razor allows to perform the so- called "texturing" of the lock of hair in a decidedly simpler manner than the scissors. More in detail, the texturing technique provides that the operator imposes an axial cutting movement on the razor and at the same time modulates the radial contrast force between blade and lock during the cutting path. By applying a more intense contrasting action in the initial step of the cut, and a weaker one in the final step, it is possible to vary the cutting length of the hair in the same lock, thus obtaining a differentiated thinning effect. This may be used to create particular hairstyles. This result is not, however, obtainable using scissors, if not through a complicated series of steps.

[0008] However, the use of the razor is not easy, in particular for inexperienced operators.

[0009] In using the razor it is, in fact, essential to precisely control the angle of the cutting edge of the blade with respect to the axis of the lock, according to the desired effect. It is also particularly difficult to keep the aforementioned angle constant as the area of the hair on which one operates varies.

[0010] Due to the shape of the razor it is also complex to accurately modulate the radial contrast force on the lock, to adapt it to the result to be obtained. This makes the use of the razor tiring, as well as timeconsuming .

[0011] The cutting action exerted by the razor has, finally, as a substantially inevitable effect, the superficial desquamation of the hair. At the end of the cut, the hair is thus devitalized and dull. The negative effects are not only of an aesthetic nature, but also of the health of the hair itself.

[0012] Due to the difficulties described above in the use of the razor, it is substantially impossible for an inexperienced operator to give a lock a jagged profile, that is, to thin out the hair of a lock in an irregular manner. In fact, if used improperly, the razor allows only a homogeneous thinning of the lock.

[0013] These problems have been partly solved by a hair cutting tool proposed on the market by the hair stylist Mario Stag! about 20 years ago under the name of SWAN. This cutting tool is the subject of the European patent

EP 1193034 Bl. [0014] More in detail, as illustrated in the accompanying Figure 1, the SWAN tool comprises a handle G which supports cutting means C. The handle G is provided at a first end with a ring R. The cutting means C comprise three blades LI, L2, L3 superimposed on each other in pairs to define two distinct V-shaped cutting edges Fl, F2. The central blade LI is fixed with respect to the handle G and extends coaxially thereto, integrally connected to a socket D formed in one piece at a second end of the handle itself. The other two blades L2, L3, on the other hand, are rotatably connected to the base D in such a way that it is possible to vary the opening angle of the two cutting edges Fl, F2. The opening angle of the two movable blades L2, L3 with respect to the fixed blade LI is adjustable by means of actuation means, which also have the function of reversibly locking the two movable blades with respect to the fixed blade LI.

[0015] In use, the SWAN tool is gripped by the operator by inserting the index or middle finger of a hand into the ring R and at the same time placing the fingertip of the thumb on the external face of the socket D.

[0016] The cutting movement that may be achieved in this way is substantially similar to that of texturing with the common razor, but with the fundamental advantage that, having previously suitably adjusted the opening of the cutting edges Fl and F2, it is possible to effectively control the angle at which the lock of hair is affected by the cutting edges, keeping it constant as the area of the hair on which one works changes.

[0017] A typical cutting procedure that may be carried out with the SWAN tool provides that, once the opening of the cutting edges has been adjusted and fixed, a first lock of hair to be cut is identified. This lock is stretched with the fingers of the free hand. With the tool, the lock is then struck with rapid and repeated cutting movements from one side to the other of the lock itself (crossing it...) . These movements are always carried out from above, perpendicularly and/or obliquely with respect to the axis of the lock.

[0018] The SWAN cutting tool has certainly represented a revolution in the hair stylist field since it allows the execution of the textured haircut in a more effective and precise manner than the traditional razor.

[0019] The use of the SWAN, however, requires an uncommon manual skill from the operator. The user is in fact required to precisely control the angle of insertion of the cutting edges inside the lock. An incorrect angle in fact leads to the tearing of the hair, or at least an incorrect cut. [ 0020 ] These operational limits have in fact prevented the spread of the SWAN tool , currently used only by a few expert hair stylists .

[ 0021 ] There is therefore still a great need in the field to have a hair cutting tool that al lows the textured haircut technique to be performed ef fectively and precisely even by non-expert operators , with better control of the cutting action and with increased comfort and quickness of use . DISCLOSURE OF THE INVENTION

DETAILED DESCRIPTION

[0042] The present invention relates to a hair cutting tool .

[0043] Such tool fits, in particular, in the field of professional hair stylist equipment.

[0044] Operationally, the cutting tool according to the invention is particularly suitable for carrying out the textured haircut technique.

[0045] Advantageously, according to particular embodiments, such tool may be used not only for the textured cut but also for the bob haircut and full shapes .

[0046] With reference to the accompanying figures, the hair cutting tool according to the invention has been indicated as a whole with reference numeral 1.

[0047] According to a general embodiment of the invention, the hair cutting tool 1 comprises:

[0048]- gripping means 10 through which the tool 1 may be handled by an operator; and [ 0049 ] - cutting means 20 which are connected to the gripping means 10 and comprise at least a first elongated blade 21 and a second elongated blade 22 with straight cutting edges .

[ 0050 ] The first blade 21 and the second blade 22 are rotationally connected to a support body 24 to rotate relative to one another around a first axis of rotation XI and to overlap each other at least partially so as to define a first V-shaped cutting edge 20a by means of the respective counter- faced cutting edges .

[ 0051 ] The hair cutting tool 1 further comprises means 25 for reversibly locking the above at least two blades 21 , 22 on the support body 24 in a predefined relative angular position around the first axis of rotation X in order to fix the angular aperture of such first V-shaped cutting edge 20a .

[ 0052 ] Operationally, the above reversible locking means 25 are operable to adj ust the predefined relative angular position of said at least two blades 21 , 22 and thereby the angular aperture of the first V-shaped cutting edge 20a .

[ 0053 ] According to an embodiment not shown in the accompanying figures , the cutting means 20 may comprise only two blades , i . e . the first blade 21 and the second blade 22 . In this case , the cutting means 20 define only one V-shaped cutting edge , adj ustable in opening by the abovementioned reversible locking means .

[ 0054 ] According to a preferred embodiment , shown in the accompanying figures , the cutting means 20 comprise at least a third elongated blade 23 with a straight cutting edge , which is rotationally connected to the above support body 24 together with the first 21 and the second elongated blade 22 to rotate relatively to one another around the above first axis of rotation XI and overlap at least partially the first elongated blade 21 to define with said first blade 21 by means of respective counterfaced cutting edges a second V-shaped cutting edge 20b . Such second V-shaped cutting edge is added to the first V-shaped cutting edge 20a defined by the first and second blades .

[ 0055 ] In this case , the above reversible locking means 25 are suitable to lock in a reversible manner on said support body 24 all three blades 21 , 22 , 23 in predefined angular positions relative to the first axis of rotation X in order to fix the angular aperture of both V-shaped cutting edges 20a, 20b .

[ 0056 ] Operationally, the above reversible locking means 25 are operable to adj ust said predetermined relative angular positions of the three blades 21 , 22 , 23 and therefore the angular aperture of both the V-shaped cutting edges 20a, 20b.

[0057] Advantageously, alternative embodiments of the invention may be provided (not illustrated in the accompanying figures) in which the cutting means comprise four or more blades in order to define three or more different cutting edges.

[0058] Preferably, each of the blades of the cutting means 20 (be they two, three or more) is rotationally connected to the support body 24. In this way, each blade may be disassembled from the support body 24, so as to be more easily maintained and possibly replaced without affecting the support body. In other words, preferably none of the blades is integral with the support body 24. Advantageously, the operator therefore has the possibility to replace the blades autonomously and with a few simple gestures, thus allowing to always have, at a negligible cost, an always efficient tool, without having to face a new purchase.

[0059] According to an alternative embodiment not shown in the accompanying figures, one of the blades of the cutting means may be fixed, and in particular be integral with the support body. In the case of three blades, the fixed blade (i.e. integral with the support body) consists of the first blade 21, i.e. the blade which is in a central position, between the second and third blades which are instead in external positions.

[ 0060 ] Pref erably, as shown in particular in Figures 6, 7, 12 and 19, each of said blades 21, 22, 23 comprises: [0061]- a disc-shaped body 21a, 22a, 23a at which the blade 21, 22, 23 is rotationally connected to the support body 24;

[0062]- a blade body 21b, 22b, 23b extending from the disc-shaped body 21a, 22a, 23a and comprising at least one straight cutting edge.

[0063] In the preferred case in which the cutting means comprise three blades, the first blade 21 (central blade) has a blade body 21b provided with two straight cutting edges formed on opposite sides, so as to be able to cooperate both with the second blade, and with the third blade in defining the two V-shaped cutting edges. The second blade 22 and the third blade 23 (external blades) instead have a blade body 22b and 23b provided with a single cutting edge, formed on the side of the blade body facing towards the central blade 21.

[0064] Preferably, as illustrated in Figures 17 to 21, the first blade 21 is flat, while the second blade 22 and the third blade 23 (if provided) are arched (by means of a slight crimping) to allow the incidence with the cutting edges of the first blade 21 in any angular position they may be.

[ 0065] Preferably, the blades 21, 22, 23 are made of stainless steel. The cutting edges of the blades 21, 22, 23 are razor sharp.

[ 0066] Preferably, as illustrated in the accompanying figures, the blades 21, 22, 23 have rounded tips, so as to limit the risk that the tool 1 may cause accidental injuries if used incorrectly.

[ 0067 ] According to the preferred embodiment of the invention, illustrated in particular in Figures 7 and 12, the disc-shaped bodies 21a, 22a, 23a of the blades 21, 22, 23 are axially overlapped along the first axis of rotation XI and rotationally engaged to each other by means of a threaded key 25 around such axis XI at a rotational housing seat 26 formed on the support body 24. [0068]More in detail, the threaded key 25 comprises a head 25a from which a threaded rod 25b extends. The latter passes through the disc-shaped bodies of the blades at axial through holes until it engages the bottom of the housing seat 26 in a suitable counter-threaded hole on which it grips.

[ 0069] Operationally, the threaded key 25 may be rotated around the first axis of rotation XI to switch between: [0070]- a locking position, in which it axially presses (by means of the head 25a) the disc-shaped bodies together against the bottom of the rotational housing seat 26, blocking the relative rotation thereof around the first axis of rotation XI; and

[0071]- an unlocking position, in which it does not axially press the disc-shaped bodies together so as to free the relative rotation thereof about the first axis of rotation XI .

[0072] The above threaded key 25 thus defines the above reversible locking means of the blades 21, 22, 23.

[0073] A typical cutting procedure that may be carried out with the tool 1 provides that, once the opening of the cutting edges has been adjusted and fixed, a first lock of hair to be cut is identified. This lock is stretched with the fingers of the free hand. With the tool, the lock is then struck with rapid and repeated cutting movements from one side to the other of the lock itself (crossing it...) . These movements are always carried out perpendicularly and/or obliquely with respect to the axis of the lock.

[0074]After having operated on the first lock, a subsequent one is identified in the immediately upper position. This is superimposed on the first, which is taken as a reference for the next cutting action. By virtue of this expedient, repeated for all subsequent locks, it is possible to keep all parts of the hairstyle mutually proportionate and coordinated.

[0075]Moving towards the end of the lock, the tool 1 (through the cutting means 20) creates multiple splinters on it, which, by adding to the splinters of the previously cut locks, determine a fringed effect, without damaging the cortex of the hair. It will thus be possible to shape the hair stably according to the most varied aesthetic needs, whether one wants to comb it smooth and compact, or whether one wants to give it maximum volume, the hairs supporting each other through the fringing obtained with the tool. It will then be possible to create jagged profiles, in the context of particularly dynamic and imaginative hairstyles, in great demand by the public, especially by the young.

[0076] To guarantee adequate versatility of the tool in terms of texture of the hair (smooth, curly, thick, frizzy, thin...) it is sufficient to vary the opening of the cutting edges as desired.

[ 0077 ] According to an essential aspect of the present invention, the above grip means 10 comprise an elongated body 11 which defines a median longitudinal axis Y. At a first end portion 11' thereof, the elongated body 11 is rotatably connected to the above support body 24 by means of a j oint 30 around a second axis of rotation X2 in such a way that it is possible to vary the inclination of the above median longitudinal axis Y with respect to a median lying plane m of the blades 21 , 22 .

[ 0078 ] According to a further essential aspect of the present invention, the tool 1 comprises means 31 for reversibly locking the abovementioned j oint 30 . Operationally, such reversible locking means of the j oint 31 are operable to adj ust the inclination of the median longitudinal axis Y with respect to the median lying plane m .

[ 0079 ] By virtue of the invention, during the execution of the textured cutting technique the user is no longer required to control precisely the angle of insertion of the V-shaped cutting edge or o f the V-shaped cutting edges inside the lock . In fact , the angle of insertion of the V-shaped cutting edge inside the lock is substantially fixed by the inclination of the longitudinal axis Y with respect to the median lying plane of the blades .

[ 0080 ] More in detail , by gripping the tool 1 at the elongated body, for example as shown in Figure 14 , and carrying out a movement useful for cutting, a semicircular rotation movement is necessarily imposed on the blades with an arm defined by the elongated body 11 . By virtue of the inclination existing between the elongated body 11 and the blades , such movement generates an angled movement of the V-shaped cutting edge on the hair lock .

[ 0081 ] Operationally, once the operator has fixed the inclination of the elongated body 11 with respect to the blades 21 , 22 , the above angled movement of the V-shaped cutting edge may be repeated over time in a constant manner with a simple rotation movement imparted on the elongated body 11 . This frees the operator from the need to continuously check the angle of the blades with respect to the hair lock, while avoiding the risk of tearing the hair and/or obtaining an incorrect cut .

[ 0082 ] The hair cutting tool 1 according to the invention therefore allows the textured haircut technique to be carried out ef fectively and precisely even by non-expert operators , with better control of the cutting action and with increased comfort and speed of use .

[ 0083 ] By virtue of the elongated element which may be rotated with respect to the cutting means , the operator is always able to also adj ust the angle of insertion of the cutting edges inside the lock, thus avoiding an extreme torsion of the wrist with an angle of 90 degrees with respect to the forearm, so as to allow the lock to be cut with minimal ef fort of the wrist during the cutting step, thus preserving himsel f /hersel f from the professional disease typical of hair stylists ( carpal tunnel syndrome ) .

[ 0084 ] With the cutting tool 1 according to the invention, the comfort of the grip is therefore extremely improved since by virtue of the elongated body which may be rotated with respect to the cutting means , the operator is able to continuously maintain a correct position of both the spinal column and the j oints , meaning shoulders , arms and cervical . Above all , this benefits the wrist as during the cutting steps it assumes a position aligned with the forearm and is no longer rotated by 90 ° with respect to the forearm itsel f , generating minimal tension on the forearm, preventing the occupational disease of carpal tunnel syndrome .

[ 0085 ] By virtue of the elongated element which may be rotated with respect to the cutting means , the operator is able to perform the cutting movements not only from top to bottom ( see the tool in the operating configuration illustrated in Figures 8 and 14 ) , but also from the bottom up ( see the tool in the operating configuration illustrated in Figures 9 and 15 ) .

[ 0086 ] Furthermore , by virtue of the elongated element which may be rotated with respect to the cutting means , the operator may cut the lock at a distance very close to the nape of the neck . In fact , the presence of the elongated body in the tool 1 according to the invention allows the operator to bring the blades closer to the nape of the neck, preventing his/her hand and the grip from being an obstacle and impediment to the movement imposed on the blades .

[ 0087 ] Pref erably, in order to facilitate the approach of the blades to the nape of the neck, the blades of the tool 1 according to the invention have a limited length, shorter than the blades of the SWAN tool . In particular, the blades of the tool 1 may have a length not exceeding 4 cm .

[ 0088 ] According to a preferred embodiment illustrated in the accompanying figures , the above median lying plane m of the blades is orthogonal to the first axi s of rotation XI .

[ 0089 ] Preferably, in the case in which the cutting means comprise only two blades , the median lying plane m of the blades passes between the two blades , in the case in which the cutting means comprise three blades , the median lying plane m of the blades passes through the central blade between the two blades .

[ 0090 ] Pref erably, the second axis of rotation X2 is parallel to the median lying plane m of the blades , while the median longitudinal axis Y is orthogonal to said second axis of rotation X2 . In this way, the angled movement of the V-shaped cutting edge obtainable with the use of the tool 1 may be set in a simpler and more immediate manner by the operator since it is directly correlated to the inclination of the elongated body with respect to the median lying plane of the blades .

[ 0091 ] Pref erably, the above j oint 30 consists of the coupling of two disc-shaped bodies 32 , 33 rotationally engaged with each other around the second axis of rotation X2 . A first disc-shaped body 32 is integral with the support body 24 of the blades 21 , 22 , while a second disc-shaped body 33 is integral with the elongated body 11 .

[ 0092 ] More in detail , the above two disc-shaped bodies 32 , 33 are rotationally engaged with each other around the second axis of rotation X2 by means of a threaded key 31 . Operationally, the threaded key 31 may be rotated around the second axis of rotation X2 to switch between a locking position, in which it axially presses the two disc-shaped bodies together, blocking the relative rotation thereof around the second axis of rotation X2 , and an unlocking position, in which it does not axially press the two disc-shaped bodies together so as to free the relative rotation thereof around the second axis of rotation X2 . The threaded key 31 defines the above reversible locking means of the j oint 30 .

[ 0093 ] Pref erably, as shown in particular in Figures 7 and 13 , the two disc-shaped bodies 32 , 33 engage each other at two respective axially facing toothed crown portions , having teeth extending radially with respect to the second axis of rotation X2 . By virtue of such configuration, during use the stresses discharged on the j oint 30 are distributed on the toothed crown portions , thus ensuring greater locking stability of the j oint even i f the tightening of the threaded key 31 has partially loosened .

[ 0094 ] Pref erably, the elongated body 11 has an at least partially curved prof ile along said median longitudinal axis Y . In particular, as illustrated in the accompanying figures , the elongated body 11 may have an S-shaped curved profile . The curved profile of fers greater ergonomics of the grip .

[ 0095 ] Advantageous ly, the elongated body 11 comprises a shaped appendix 12 , preferably consisting of an open or closed ring . Operationally, such ring may be used as a seat for inserting a finger of the operator so as to make the grip of the handle easier and safer and therefore the tool 1 easier to handle . [ 0096 ] Preferably, the above shaped appendix 12 is in proximity to a second end portion 11" of the elongated body 11 , that is , in the oppos ite position to the cutting means 20 .

[ 0097 ] Advantageous ly, the tool 1 may comprise a housing seat 40 for a razor blade 41 . Such seat 40 is made at a second end portion 11" of the elongated body 11 , that is , in the opposite position to the cutting means 20 .

[ 0098 ] Pref erably, the above housing seat 40 is fixed with respect to the elongated body 11 and is oriented with respect to the elongated body 11 in such a way that the cutting edge of a razor blade housed in said seat 40 forms an obtuse angle with the median longitudinal axis Y of said elongated body 11 . Preferably, such obtuse angle is comprised between 100 ° and 150 ° .

[ 0099 ] Advantageous ly, the cutting tool 1 according to the invention may be gripped in di f ferent ways according to the type of cut to be obtained .

[ 00100 ] More in detail , when used for the purpose of textured haircut , the tool , once it is given the desired configuration according to the cutting angle to be obtained by rotating the handle with respect to the blades , is preferably gripped by the operator with his/her two thumb and middle fingers on a portion of the elongated body far from the cutting means and at the same time resting the fingertip of the index finger again on the elongated body, but in proximity to the j oint 30 . Such type of grip is shown in Figure 14 .

[ 00101 ] When used for aligning the perimeter of the cut , the tool 1 , once it is given the desired configuration according to the cutting angle to be obtained by rotating the handle with respect to the blades , is pre ferably gripped by the operator with his/her ring finger inserted in the ring ( arranged on a portion of the elongated body far from the cutting means ) and with the thumb or middle finger resting on the j oint 30 depending on the cutting side . Such type of grip is shown in Figure 15 .

[ 00102 ] In the preferred case in which the cutting tool 1 is provided with a seat for a razor, the tool may also be used as a normal razor, with the dual purpose of razor (barber ) and stripping with razor ( texturing) . In this case , the blades of the cutting means are closed together and approached to the elongated body . When used for the dual purpose of razor (barber ) and stripping with razor ( texturing) the tool 1 , once it is given the desired configuration by rotating the handle with respect to the blades , is gripped by the operator with the j oint arranged between the little finger and the ring finger and with the thumb on the handle portion which defines the housing seat o f the razor . [ 00103 ] The invention allows numerous advantages to be obtained which have been explained in the course of the description .

[ 00104 ] The hair cutting tool according to the invention allows the textured haircut technique to be carried out ef fectively and precisely even by non-expert operators , with better control of the cutting action and with increased comfort and speed of use .

[ 00105 ] The hair cutting tool according to the invention is also constructively simple to make , since there are no complex pieces to make and to assemble .

[ 00106 ] The invention thus conceived therefore achieves its intended purposes .

[ 00107 ] Obviously, in its practical embodiment , it may also assume forms and configurations di f ferent from the one illustrated above without thereby departing from the present scope of protection .

[ 00108 ] Moreover , all details may be replaced by technical equivalent elements and the dimensions , the forms and the materials employed may be any, depending on the needs .
