Definitions
- the present invention relates to pins for cosmetic use.
- the present invention relates in particular to tweezers for cosmetic use.
- Tweezers are small pliers formed from a generally flat end which is extended into two branches acting like a spring and which make it possible to grasp very small objects or to perform high-precision work. Some tweezers are intended for cosmetic use. Injury generally used for hair removal, their small size allows in particular to grasp and pluck the hairs with precision.
- Tweezers of the prior art are generally fine and long Their branches are therefore narrow and elongated This commonly accepted form has several disadvantages
- the handling of tweezers of the prior art can prove to be difficult, in particular for people with reduced dexterity such as for example the elderly.
- the tweezers of the prior art also tend to roll involuntarily between the fingers of the user, for example when the latter presses too strongly or crookedly on the branches.
- An object of the present invention is to provide tweezers for cosmetic use which do not have the disadvantages of tweezers for cosmetic use of the prior art.
- forceps for cosmetic use comprising two branches comprising a metal end for grasping small objects, the maximum width of the two branches being greater than half the average width of the support surface of the thumb of a medium sized adult user when actuating pliers and the maximum length of the two arms being less than the average thumb length of a medium sized adult. Even a person with reduced dexterity is thus able to easily grasp the pliers of the invention between two fingers to close them.
- the width of the branches makes it possible to prevent the latter from sliding between the user's fingers and / or that the clamps do not turn involuntarily when they are closed, even strongly or crookedly.
- FIG. 1 is a perspective view of tweezers according to a preferred variant of the invention
- FIG. 2 is a top view of the tweezers of FIG. 1
- FIG. 3 is a profile view of the tweezers of FIG. 1
- Figure 4 is a perspective view of tweezers according to a preferred embodiment of the invention comprising additional elements fixed on the branches
- Figure 5 is a top view of the tweezers of Figure 2
- Figure 6 is a profile view of the tweezers of Figure 2.
- the tweezers of the invention comprise a preferably metallic frame 1 comprising an end 2, preferably narrow and for example flat, allowing precise grasping of small objects.
- the shape of the end 2 is preferably adapted to the intended use of tweezers. It can, for example, be pointed, angled, etc.
- the tweezers of the invention are intended for cosmetic use.
- the end 2 is thus preferably adapted to this kind of use, in particular for gripping and pulling out human hair.
- the maximum width of the branches 3 is for example at least equal to half, preferably both third, of the average width of the thumb support area of an adult of average build when actuating tweezers, so as to provide the frame 1 with rigidity in bending and in torsion along the longitudinal axis and thus offering optimal comfort and precision of use.
- the maximum width of the branches 3 is at least equal to the average width of the support area of the thumb of an adult of average build when actuating the tweezers.
- the maximum length of the branches 3 is preferably less than the average thumb length of a medium-sized adult.
- the average width of the support zone of the thumb of an adult of average build when actuating tweezers has been evaluated at around 20mm while the average length of the thumb is around 55mm, men and women combined
- the maximum width of the branches3 is thus preferably greater than 20mm, while their maximum length is preferably less than 55mm.
- the maximum width of the branches 3 is at least equal to one third of their maximum length.
- the maximum width of the branches 3 is at least equal to half their maximum length.
- the branches 3 widen from the end 2 over less than half their length and then retain their maximum width up to the connection zone 32 connecting the two branches 3 and being at the other end.
- the outer dimensions of the widest part of branches3, which thus extends over at least half of their length, are well sena 'ably those of a square.
- the end 2 is preferably narrow, similar to that of the prior art brushes, so as to allow easy and isolated gripping of very small objects such as, for example, human hair, etc.
- the maximum width of the end 2 is thus preferably less than a third of the maximum width of the branches 3. According to a still preferred version, the maximum width of the end 2 is preferably less than one fifth of the maximum width of the branches 3.
- each branch 3 is interconnected by means of flexible blades 30 preferably formed in the widest part of the branches 3, acting in the manner of a spring against the closing of the tweezers 1.
- each branch 3 comprises two blades 30 , each blade 30 extending the corresponding blade 30 of the other branch 3.
- the spring effect keeping the tweezers 1 open is preferably essentially ensured by the flexibility of the blades 30 themselves
- the flexibility of the Iames30 is for example determined and controlled by the formation of a recess 31 on each blade 30 locally reducing the thickness of the latter Lesévidements31 allow, in particular by the choice of their dimensions and of their symmetry, to determine with precision the degree of flexibility of each blade 30 as well as the zone and the direction according to which the essence of the flexibility will be effected when using the tweezers 1.
- the vents 31 are preferably located as far as possible from the end 2 in order to minimize the angle formed between the branches 3 when the tweezers are closed and to guarantee optimal transmission on the end 2 of the force exerted on Iesbranches3 by the user.
- the blades 30 of each branch 3 are preferably connected to the corresponding blades 30 of the other branch 3 by connecting zones 32 which are practically not deformed when the tweezers 1 are actuated, even if the bearing force on the branches 3 is very high.
- the connecting zones 32 are for example of the same material as the blades 30 but substantially wider than these latter, so that their rigidity is also substantially higher. The rigidity of the connection zones 32 guarantees in particular that the end 2 of the tweezers closes correctly, avoiding any lateral offset between the branches 3.
- the connecting zones 32 determine a certain spacing of the branches 3 between them which allows that, when the tweezers of the invention are open in the rest position, the opening angle between the branches 3 is relatively small , or even that the branches 3 are substantially parallel
- the small opening angle between the branches 3 when the end 2 is open thus provides the tweezers of the invention with optimal comfort of use and an improved aesthetic appearance despite relatively short desbranches3
- the two blades 30 of the same branch 3 are preferably arranged on each side of the branch 3 so as to be as far apart as possible from one another. This arrangement allows optimal control of the precision of the closing of the flat end 2 during actuation of the tweezers 1.
- the spacing of the blades 30 connecting the branches 3 between them makes it possible in fact to prevent the latter from shifting laterally relative to each other during their closing.
- the number of blades 30 of each branch 3 can be chosen when designing the tweezers of the invention, for example to adapt the last tweezers to a particular use and / or give them a determined resistance.
- the branches 3 of the tweezers 1 of the invention can thus for example comprise one, two, three flexible blades or more depending on the aesthetic appearance and / or the desired operating comfort.
- the frame 1 of the tweezers of the invention is preferably formed by electroerosion and then by folding a metal plate. Both are thus branches3 Vietnameseupeesde symetriqueset manner interconnected ellespar the connecting areas 32.
- the folding is carried out with the greatest Préci has one to ensure proper alignment branches 3 and the desired spacing therebetween Those skilled in the art will however understand that other embodiments are also possible in the context of the invention.
- each branch 3 is for example manufactured separately and then fixed directly or through a connecting element by the end of its blades 30 to another branch 3. The fixing is done for example by welding, by gluing, etc.
- such an embodiment has the disadvantage that it is more expensive, more fragile and generally less precise.
- the tweezers of the invention are preferably known ' apart by the two arms 3 by a user, for example between the thumb and the index finger of the same hand.
- the tweezers of the invention are preferably gripped with the thumb pointing upwards while the index finger is curved against the lower branch.
- Such gripping of tweezers allows the user to exert a greater force on the end 2 than in the case of tweezers of the prior art which are generally actuated with the tips of the fingers
- the user exerts pressure on the external surfaces of the branches 3, preferably on an area located between the recesses 31 and the flat end 2.
- the flexible Iames 30 then bend essentially in the area of the recess 31 while the rest of the branches 3 keep their original shape, which has the effect of closing the flat end 2, for example to grab a small object.
- the tweezers 1 then open under the spring force of the blades 30 which return to their initial position.
- the end 2 is offset from the branches 3 and is connected to the latter along an axis different from their longitudinal axis. This off-center and off-center position of the end 2 makes it possible to prevent the wide part of the frame 1 from hampering the visibility of the user when using the tweezers of the invention.
- This position also allows good maintenance of the wide part of the frame 1 in the palm of the user's hand while ensuring optimal access to the end 2.
- Those skilled in the art will however understand that other positions are possible for the end 2. It can in particular be centered with respect to the branches3 and / or connected to the latter along an axis parallel to their longitudinal axis.
- the width of the branches3 makes it possible to offer the user a large bearing surface for actuating the tweezers against the spring force of the blades 30. Even a person with reduced dexterity is thus able to easily grasp the tweezers of the invention between two fingers to close them.
- the width of the branches 3 makes it possible to prevent the latter from sliding between the fingers of the user and / or that the tweezers do not turn involuntarily when they are closed, even strongly or crookedly.
- the width of the branches 3 also offers better stability of the armature 1 relative to the end 2.
- the width of the frame 1, in particular the large surface area of the branches 3, also makes it possible to easily attach additional elements to it, making it possible, for example, to further enlarge the bearing surface on the branches 3, to provide a surface more pleasant and less slippery contact than that of the frame and / or of offering the tweezers of the invention a particular appearance, for example for aesthetic, ergonomic and / or advertising reasons.
- the additional element or elements fixed to the branches 3 also make it possible to bring new functionalities to the tweezers of the invention.
- the branches 3 comprise fixing elements, for example openings 38, 39 and / or notches 37 making it possible to fix there, for example by removable clipping additional elements made of molded or injected synthetic material and provided with fixing elements adequate to cooperate with those of the branches 3.
- each branch 3 comprises a cover 9 fixed on its outer surface and covering it almost entirely.
- the covers 9 thus give the tweezers a particular aesthetic appearance while further widening the bearing surfaces which can be used to actuate them.
- Each cover 9 preferably comprises fixing elements 97, 99 partially visible on Iesfigures4 and 6 and cooperating with the openings 39 and Ieséchancrures37 of the corresponding branch 3.
- the covers 9 are in the shape of a heart and therefore have an obvious aesthetic appearance. Those skilled in the art will however understand that other covers can also be envisaged in the context of the invention.
- the shape and / or material of the latter can in particular be varied at will in order to give the tweezers of the invention the ease of handling and / or the desired aesthetic appearance.
- the covers can for example offer a particularly ergonomic bearing surface. , suitable for example for left-handers or right-handed They can also be decorative elements resembling jewelry and include, for example, precious materials, gemstones, etc. They may also include advertising inscriptions. A person skilled in the art will also understand that the additional elements fixed on the frame 1 may not entirely cover its external surface.
- the additional elements fixed on the branches 3 provide additional functionalities to the tweezers 1 of the invention.
- at least one of the additional elements includes for example a watch, a thermometer, a lamp for example to light the end 2 when pressure is exerted on the branches 3, etc.
- Leschevaires for example the covers 9, are preferably removably attached to the legs 3 so that they are easily interchangeablessans particular tool, or risk of damaging tweezers l irreversibly.
- the user is thus able to adapt the tweezers of the invention according to his taste and / or his needs by fixing there the additional elements of his choice among those at his disposal.
- An advantage of the tweezers 1 of the invention is that, given the width of the branches 3 and their short length, they are not considered to be dangerous objects according to the new standards in force in the field of air transport. They can thus be taken by a traveler in an airplane cabin and used during the trip.
- the two branches 3 of the tweezers 1 are substantially wider than the flat end 2, preferably at least as wide as the thumb of a medium-sized adult user.
- only one branch is wide and comprises for example fastening elements for fixing an additional element, while the other branch is narrow and elongated, similar to a branch of tweezers of the prior art .
- the frame 1 of the tweezers of the invention is metallic and comprises the end 2 of the same material.
- a frame made of another material for example of molded or injected synthetic material, and comprising a metal end 2 constituted for example by a pair of metal spikes fixed, for example attached, to the synthetic frame.
