Abstract

The invention relates to scissors, comprising first and second blades which are mounted so as to pivot relative to one another about an axis of rotation, an eyelet secured to the first blade, the axis being positioned between the eyelet and the first blade.

Description

[0001] The present invention relates to the technical field of articulated objects. More specifically, it relates to the technical field of scissors, and in particular scissors intended for cutting hair.

[0002] For the purposes of this description, an interval described by the expression "between [...] and [...]" includes the bounds. For example, the interval "between 1 and 2" includes the two values ​​"1" and "2" as well as all values ​​that are both strictly greater than 1 and strictly less than 2.

[0003] In this description, the term "approximately" preceding a numeric value means that the value can be changed by plus or minus 10%. In the specific case of a numeric value acting as an interval boundary, the term "approximately" means that the lower boundary can be reduced by 10% or the upper boundary can be increased by 10%. It is also possible to omit the term "approximately" preceding a numeric value.

[0004] Scissors, and in particular those known for the practice of hairdressing, generally have two blades mounted pivoting relative to each other around an axis.

[0005] Each blade has its own eyelet to which it is attached. The axle is positioned between a blade and its eyelet. Each eyelet allows a user to place one or more fingers on it to pivot the blade around the axle.

[0006] In practice, most often, one eyelet is reserved for the user's thumb, and the other is reserved for one or more fingers other than the thumb.

[0007] For the purposes of this description, a "user" is a user of scissors. This could include, for example, a hairdresser.

[0008] The practice of hairdressing requires a large number of movements and changes in the position of the scissors.

[0009] Users most often perform these movements through rotations and displacements of the wrist.

[0010] Such wrist movements and rotations are the cause of numerous musculoskeletal disorders (MSDs), such as tendinitis, which can be particularly debilitating for hairdressing professionals. These conditions are very common among hairdressers, who are sometimes forced to stop working as a result.

[0011] When cutting an individual's hair, the position of the scissors, and in particular the cutting plane, must be substantially constant relative to the surface of the scalp, regardless of where the cut is made, on and around the individual's head.

[0012] Scissors are most often held by inserting the thumb into one eyelet of the scissors, and at least one finger into the other eyelet of the scissors.

[0013] The cutting motion is mostly performed by the thumb, while the other fingers remain relatively still.

[0014] When the thumb is fully engaged in the eyelet, it cannot be used for anything other than operating the scissors.

[0015] In particular, it will not be able to act on the position of the cutting plane in relation to the scalp, or only in a very marginal way.

[0016] Thus, when using scissors, many extreme and potentially traumatic movements will have to be made by other joints, particularly the wrist.

[0017] It is in this context that users of scissors are particularly exposed to a large number of health risks, including: The aforementioned musculoskeletal disorders (MSDs), linked to the user's uncomfortable and often repetitive postures and movements, are extremely frequent and lead to disabling osteoarticular pathologies; cuts, which in some cases can lead to direct contamination, particularly with regard to blood-borne diseases.

[0018] As mentioned previously, depending on the position of the head and where hair needs to be cut, adapting the position of the scissors is sometimes difficult, and requires in particular a variable rotation of the wrist including extreme positions, which is problematic for the user's health.

[0019] When the user suffers from particular pathologies, especially osteoarthritis, these problems are further amplified.

[0020] In earlier art, a number of approaches were proposed to improve the ergonomics of hairdressing scissors.

[0021] First, an attempt was made to create scissors with branches bent at right angles.

[0022] Thus, in application WO2002094512 (KIM), scissors are disclosed whose arms are at right angles or substantially at right angles.

[0023] In application US5232000 (CHIAVARAS), scissors with right-angled arms are also described, presented as being more ergonomic.

[0024] In practice, these scissors do not mitigate risks and are not ergonomic. Furthermore, their wear, and in particular the wear of the hinge, is premature due to the position of the eyelets.

[0025] Next, attempts were made to create scissors featuring one or more hinges intended to improve ergonomics.

[0026] Thus, in US application 5469624 (BRENTON), scissors are disclosed comprising a thumb eyelet mounted on a hinge perpendicular to the thumb branch; this eyelet can be removed and its size adjusted to the user. In US application 20050204569 (BRENTON), scissors are disclosed comprising an incomplete thumb eyelet mounted on a hinge perpendicular to the thumb branch; this incomplete eyelet can be removed and its size adjusted to the user.

[0027] Other applications contain similar disclosures: US20080172886 (DONG HO JUN), US20100212165 (PARNAZZINI ET AL.) or WO2007133567 (FOX).

[0028] In application US20050005456 (WANG ET AL.), scissors are disclosed comprising a thumb eyelet mounted on a hinge arranged in the extension of the thumb arm.

[0029] Finally, in application WO2014132279 (DE STEFANO), scissors comprising two rotating eyelets are disclosed, presented as allowing better ergonomics.

[0030] In practice, these solutions offer no added value to the user from a health perspective. Worse, since the hinges are free to rotate during cutting, this complicates the user's work and maximizes the risk of cuts.

[0031] There is a need for scissors with improved ergonomics, capable of reducing the risk of musculoskeletal disorders and improving user grip, while also reducing the risk of cuts.

[0032] The invention aims to resolve one or more of the drawbacks identified in the prior art.

[0033] The invention thus relates to scissors 1, comprising: of the first and second blades 21, 22 mounted pivoting relative to each other around an axis 91 of rotation; an eyelet 3 fixed to the first blade 21, the axis 91 being positioned between the eyelet 3 and the first blade 21; characterized in that: the eyelet 3 defines a closed contour 32 encircling a passage section 34, the eyelet 3 comprising an element 331, 333 projecting inwards towards the interior of the passage section 34 relative to the closed contour, according to an orthogonal projection onto a cutting plane 92 perpendicular to the axis of rotation 91.

[0034] The scissors 1 according to the invention offer added comfort and help prevent injuries and muscle fatigue. One of the most significant advantages of using the scissors 1 according to the invention, particularly for hairdressers, is the reduction of muscle fatigue. The scissors 1 according to the invention allow for a more balanced distribution of pressure on the fingers, which reduces strain on the muscles of the hand, wrist, and forearm.

[0035] Another advantage is improved precision and control. Scissors 1 according to the invention offer a more comfortable and stable grip, allowing the user, and in particular the hairdresser, to better control their movements, improve their precision and reduce the risk of tremors.

[0036] The use of scissors 1 according to the invention can also help prevent musculoskeletal disorders such as tendinitis, epicondylitis, or joint pain. By reducing tension on the muscles, tendons, and nerves of the fingers, hands, and forearms, scissors 1 according to the invention can help prevent these health problems.

[0037] In addition, the scissors 1 according to the invention offer increased comfort, especially for hairdressers who spend long hours working with scissors.

[0038] By reducing muscle tension and the risk of musculoskeletal disorders, the scissors 1 according to the invention can contribute to their overall well-being. In short, the use of scissors 1 according to the invention can help improve the performance and comfort of users, and in particular hairdressers, while reducing the risk of injury and muscle fatigue.

[0039] It should be noted that the scissors according to the invention will be particularly advantageous when cutting hair while standing on end. Indeed, during such a cut, the scissors are held in the right hand (for a right-handed person) and a comb is held in the left. During the cut, the right hand holding the scissors is parallel to the ground and positioned 5 cm to 30 cm above the head. In this cutting position, the scissors according to the invention allow the thumb to remain free, thus reducing strain on the right wrist.

[0040] In one embodiment, said scissors 1 are made of a rigid material, preferably a metal or a metal alloy, preferably chosen from the group consisting of steel, stainless steel and titanium.

[0041] In one embodiment, said scissors 1 comprise a rigid material, preferably a metal or a metal alloy, preferably selected from the group consisting of steel, stainless steel and titanium.

[0042] In one embodiment, the eyelet 3 is made of a rigid material, preferably a metal or a metal alloy, preferably chosen from the group consisting of steel, stainless steel and titanium.

[0043] In one embodiment, the eyelet 3 comprises a rigid material, preferably a metal or a metal alloy, preferably selected from the group consisting of steel, stainless steel and titanium.

[0044] In one embodiment, the scissors 1 are made of a single material. In some cases, this is advantageous because it reduces wear.

[0045] In one embodiment, the scissors 1 are made of several different materials. In some cases, this is advantageous because it allows for easier manufacturing.

[0046] For example, the material of thumb eyelet 3 may be different from that of blades 21 and 22.

[0047] This is particularly advantageous when the thumb eyelet is especially difficult to produce. It may be advisable to produce the thumb eyelet from a more ductile material than that used for the blades.

[0048] In one embodiment, these scissors are scissors for hairdressing. This embodiment is preferred because ergonomics are particularly important in hairdressing due to the repetitive nature of certain movements.

[0049] In one embodiment, the eyelet 3 is fixed to the lever 51. This means that the eyelet 3 cannot be moved independently of the lever 51. In particular, the eyelet 3 is not mounted on a hinge or any other means allowing the eyelet to be moved relative to the lever 51. This makes the scissors more ergonomic.

[0050] In one embodiment, said scissors 1 comprise a single hinge at the axis of rotation 91.

[0051] In one embodiment, said scissors 1 do not include any hinge other than that present at the axis of rotation 91.

[0052] In one embodiment, the scissors 1 do not include a hinge at the eyelets. In another embodiment, the scissors 1 do not include a hinge at both eyelets. This embodiment is preferred because it is beneficial for hairdressers who spend long hours cutting hair. Without a hinge at the eyelets, the tension is distributed evenly across the fingers, thus reducing fatigue and joint strain. This can also help prevent injuries from prolonged use of the scissors. Furthermore, scissors without a hinge at the eyelets can offer greater freedom of movement and better control of the cut, allowing hairdressers to work more efficiently.

[0053] In one embodiment, the scissors 1 are each made of a continuous piece of material. In another embodiment, the scissors 1 are each made of a continuous piece of material without a hinge.

[0054] In one embodiment, the length of the scissors is between approximately 10 cm and approximately 20 cm, preferably between approximately 12.5 cm and approximately 17.5 cm. Preferably, the length of the scissors is approximately 15 cm.

[0055] In one embodiment, the length from the end of the blades to the axis of rotation 91 is between approximately 5 cm and approximately 10 cm, preferably between approximately 7.5 cm and approximately 12.5 cm.

[0056] In one embodiment, the length from the end of the eyelets to the axis of rotation 91 is between approximately 5 cm and approximately 10 cm, preferably between approximately 6 cm and approximately 8 cm.

[0057] In practice, levers 51 and 52 connect each of the two eyelets (including eyelet 3) to blades 21 and 22.

[0058] In one embodiment, lever 51 is straight. In another embodiment, lever 52 is straight. In another embodiment, both levers 51 and 52 are straight.

[0059] Straight levers offer several advantages. First, their ergonomic design allows for a comfortable grip and reduces muscle fatigue during extended cutting sessions. Straight levers also provide greater stability and control, resulting in a more precise and clean cut. Furthermore, scissors according to the invention with straight levers are often lighter than models with curved levers, allowing for longer use without pain or strain in the wrists and fingers.

[0060] In one embodiment, said eyelet 3 is a thumb eyelet. This means that it is intended to be preempted by the user's thumb.

[0061] In one embodiment, the eyelet 3 and the first blade 21 are in one piece.

[0062] In one embodiment, said scissors 1 are straight scissors.

[0063] In one embodiment, said scissors 1 are offset scissors.

[0064] In one embodiment, said scissors 1 are sculpting scissors.

[0065] In one embodiment, said scissors 1 are micro-serrated scissors.

[0066] In one embodiment, the scissors 1 are right-handed scissors. This embodiment is preferred because most users are right-handed.

[0067] In one embodiment, said scissors 1 are left-handed scissors.

[0068] Adapting the scissors for right- and left-handed users is important, for obvious ergonomic reasons. In all cases, the thumb is intended to be in contact with the eyelet 3 of the first blade 21.

[0069] When manipulating the scissors 1, the user's thumb comes into contact with the eyelet 3, and the protruding element 331, 333 prevents the thumb from entering too deeply into the eyelet 3. Thus, problematic wrist movements can be transferred to the thumb, allowing the user to avoid MSDs and their consequences.

[0070] In summary, the closed contour allows the user to have a true support point for the thumb, enabling them to transfer complex and traumatic movements, particularly from the wrist, directly to the fingers, and especially to the thumb.

[0071] In one embodiment, the scissors 1 are characterized in that said element is selected from the group consisting of a lug 331 having a free end 332 or a strip 333 connecting two locations of the closed contour 32.

[0072] In one embodiment, said element is a strip 333 connecting two locations of the closed contour.

[0073] In one embodiment, said element is a lug 331 having a free end. This embodiment is preferred because it provides a good means of support for the thumb while saving material.

[0074] In one embodiment, said free end has a rectangular cross-section.

[0075] In one embodiment, said free end is pointed in shape.

[0076] In one embodiment, the scissors 1 are characterized in that said element 331 protrudes into the passage section 34 over a length of at least about 5 millimeters.

[0077] In one embodiment, said element 331 protrudes into the passage section 34 over a length of at least about 10 millimeters.

[0078] In one embodiment, said element 331 protrudes into the passage section over a length of between approximately 5 millimeters and approximately 30 millimeters.

[0079] In one embodiment, said element 331 protrudes into the passage section over a length of between approximately 10 millimeters and approximately 25 millimeters.

[0080] In one embodiment, said element 331 protrudes into the passage section over a length of approximately 15 millimeters.

[0081] In one embodiment, the scissors 1 are characterized in that said element is a protruding lug 331 with a pointed free end 332.

[0082] In one embodiment, the scissors 1 are characterized in that said closed contour 32 comprises a part 321 included in said cutting plane 92 and a part offset 322 from said cutting plane 92 so that the closed contour 32 delimits a recess 323 in said cutting plane 92.

[0083] This embodiment is particularly preferred. Indeed, the recess 323 created allows the thumb relatively free movement, especially regarding the orientation of the scissors. The combination of the element 331, 333 projecting inwards into the passage section 34 relative to the closed contour, and the recess 323, allows the thumb to have maximum influence on the position of the scissors, thus transferring a maximum of movement from the wrist and other joints to the user's thumb.

[0084] In one embodiment, said offset part extends at least 1 cm from the cutting plane 92.

[0085] In one embodiment, said offset part extends at least 2 cm from the cutting plane 92.

[0086] In one embodiment, said offset part is offset by an angle A between approximately 90° and approximately 170°.

[0087] In one embodiment, said offset part is offset by an angle A between approximately 100° and approximately 160°.

[0088] In one embodiment, said offset part is offset by an angle A between approximately 110° and approximately 150°.

[0089] In one embodiment, said offset part is offset by an angle A between approximately 120° and approximately 150°.

[0090] In one embodiment, said offset part is offset by an angle A between approximately 125° and approximately 145°.

[0091] In one embodiment, said offset part is offset by an angle A between approximately 135° and approximately 140°.

[0092] In one embodiment, the offset part is offset by an angle A of approximately 138°. The closer angle A is to 138°, the greater the ergonomics of the scissors 1.

[0093] In one embodiment, the scissors 1 are characterized in that said recess 323 is positioned on an external lateral edge of the closed contour 32.

[0094] This embodiment is particularly preferred. Indeed, it allows the thumb to maintain good pressure on lever 51, while also providing it with the possibility of a large number of positions that correspond to the different orientations of the scissors during hair cutting.

[0095] In one embodiment, the scissors 1 are characterized in that the orthogonal projection of said recess 323 onto the cutting plane 92 covers at least the angular sector [40°, 140°] around point O with respect to vector OP, with point O defined as the geometric center of the orthogonal projection of the closed contour 32 onto the cutting plane 92, with point P defined as the intersection between the cutting plane 92 and the axis of rotation 91.

[0096] In one embodiment, the scissors 1 are characterized in that the orthogonal projection of said recess 323 onto the cutting plane 92 covers at least the angular sector [50°, 130°] around point O with respect to vector OP, with point O defined as the geometric center of the orthogonal projection of the closed contour 32 onto the cutting plane 92, with point P defined as the intersection between the cutting plane 92 and the axis of rotation 91.

[0097] In one embodiment, the scissors 1 are characterized in that the orthogonal projection of said recess 323 onto the cutting plane 92 covers at least the angular sector [60°, 120°] around point O with respect to vector OP, with point O defined as the geometric center of the orthogonal projection of the closed contour 32 onto the cutting plane 92, with point P defined as the intersection between the cutting plane 92 and the axis of rotation 91.

[0098] In one embodiment, the scissors 1 are characterized in that the orthogonal projection of said recess 323 onto the cutting plane 92 covers at least the angular sector [70°, 110°] around point O with respect to vector OP, with point O defined as the geometric center of the orthogonal projection of the closed contour 32 onto the cutting plane 92, with point P defined as the intersection between the cutting plane 92 and the axis of rotation 91.

[0099] In one embodiment, the scissors 1 are characterized in that the orthogonal projection of said recess 323 onto the cutting plane 92 covers at least the angular sector [80°, 100°] around point O with respect to vector OP, with point O defined as the geometric center of the orthogonal projection of the closed contour 32 onto the cutting plane 92, with point P defined as the intersection between the cutting plane 92 and the axis of rotation 91.

[0100] In one embodiment, the scissors 1 are characterized in that the orthogonal projection of said recess 323 onto the cutting plane 92 covers at least the angular sector [85°, 95°] around point O with respect to vector OP, with point O defined as the geometric center of the orthogonal projection of the closed contour 32 onto the cutting plane 92, with point P defined as the intersection between the cutting plane 92 and the axis of rotation 91.

[0101] In one embodiment, the scissors 1 further include a support lug 35 projecting inwards towards the passage section 34 relative to the closed contour 32.

[0102] The presence of a support lug 35 is particularly desirable; it allows for easier opening of the scissors with the upper face of the thumb.

[0103] In a particularly preferred embodiment, a recess 323 is present, and the scissors further include a support lug 35 projecting inwards towards the passage section 34 relative to the closed contour 32 and positioned adjacent to said recess 323. In this latter case, there is a real synergy between the recess 323 allowing freedom of the thumb and the support lug 35 which allows the scissors to maintain ease of opening between two approaches of the levers 51 and 52, i.e. between two cutting movements.

[0104] In a particularly preferred embodiment, the support lug 35 also projects beyond the cutting plane 92. figure 12 illustrates this particular method of implementation, which is preferred because it allows maximum maneuverability of the scissors.

[0105] In a particularly preferred embodiment, the support lug 35 and the element 331 (for example, a lug having a free end 332) originate in opposite portions of said closed contour 32. figure 13 illustrates this particular embodiment, which is preferred because it allows the thumb to be properly channeled between said support lug 35 and said element 331. The thumb is well centered between these two elements, which is advantageous.

[0106] In one embodiment, said support lug 35 has a length of at least about 1 millimeter, preferably of at least about 2 millimeters, preferably of at least about 3 millimeters, preferably of at least about 4 millimeters.

[0107] In one embodiment, said support lug 35 has a length of about 1 millimeter, preferably about 2 millimeters, preferably about 3 millimeters, preferably about 4 millimeters.

[0108] In one embodiment, the scissors 1 include two support lugs 35a and 35b.

[0109] In one embodiment, the scissors 1 include two support lugs 35a and 35b, each projecting inwards from the passage section 34 relative to the closed contour 32. In a preferred embodiment, these two lugs are located on either side of the closed contour 32.

[0110] The presence of several support lugs 35 is particularly desirable; it allows for easier opening of the scissors with the upper face of the thumb, with a distribution of loads to reduce friction on the skin of the thumb.

[0111] In one embodiment, at least one support lug 35 and the element 331 originate within the same portion of the closed contour 32.

[0112] In one embodiment, the scissors 1 are characterized in that the offset part 322 and said protruding element 331 are offset on the same side with respect to said cutting plane 92.

[0113] In one embodiment, the scissors 1 are characterized in that the offset part 322 and said projecting element 331 are located on the same side with respect to said cutting plane 92.

[0114] In one embodiment, the scissors 1 are characterized in that said eyelet 3 is mounted removably relative to the first blade 21 by means of a fixing interface 6, the fixing interface 6 allowing the eyelet 3 to be secured in several angular positions around an axis 93 perpendicular to the axis of rotation 91 of the first and second blades 21, 22.

[0115] In one embodiment, there are 12 of these angular positions, and they are therefore separated from each other by an angle of 30°.

[0116] In one embodiment, there are 12 of these angular positions, and they are therefore separated from each other by an angle of 30°, because 30 times 12 equals 360° (a complete rotation).

[0117] In one embodiment, the scissors 1 are characterized in that said element is offset from the first blade 21 in a direction corresponding to the axis of rotation.

[0118] The invention also relates to the use of scissors 1 according to the invention to reduce the risk of occurrence of MSDs.

[0119] The invention also relates to scissors 1 according to the invention intended to be used to reduce the risk of occurrence of MSDs.

[0120] The invention also relates to the variants described herein. Those skilled in the art will understand that each of the features of these variants can be combined, without thereby constituting an intermediate generalization.

[0121] Other features and advantages of the invention are clearly apparent from the description, by way of example and not limitation, with reference to the accompanying drawings, in which: There figure 1 Figure 1 illustrates scissors 1 for hairdressing according to the invention, comprising first and second blades 21, 22 mounted pivoting relative to each other about the axis 91 of rotation.

More precisely, the eyelet 3 defines a closed contour 32 surrounding a passage section 34 and includes an element 331, which is a lug having a free end 332 projecting inwards towards the passage section 34 relative to the closed contour, according to an orthogonal projection onto the cutting plane 92 perpendicular to the axis of rotation 91. A portion 322 of the eyelet 3 is offset relative to the cutting plane 92.A support lug 35 projecting inward from the passage section 34 relative to the closed contour 32 is shown, and a recess 323 is positioned on an outer lateral edge of the closed contour 32 and adjacent to said recess 323.

The closed contour 32 has a portion 321 included in the cutting plane (not shown), and a portion 322 offset from said cutting plane, so that the closed contour defines a recess 323 in said cutting plane. The figure 6 represents the same eyelet 3 as the one shown in figure 5 , seen from another angle. The description of the figure 5 corresponding to the numbers present in figure 5 is therefore applicable to this figure 6 . There figure 7 is a detail view of an eyelet 3 corresponding to a lever 51.

The mounting interface allows the user of the scissors to position the eyelet 3 at the desired angle before moving the scissors. During a haircut, the user can use one or more positions as needed. figure 11 is an exploded detail view of an eyelet 3 corresponding to a lever 51. The passage section 34 relative to the closed contour 32 is shown. The eyelet 3 has a strip-like element 333.

The fastening interface allows the user of the scissors to position the eyelet 3 at the desired angle before moving the scissors. During a haircut, the user can use one or more positions as needed. figure 12 is a detailed view of an eyelet 3 corresponding to a lever 51. Eyelet 3 differs from the one shown in figure 1 by the fact that the support lug 35, which as in the framework of the figure 1 is projecting inwards from the passage section 34 relative to the closed contour 32, and is also projecting from the cutting plane 92. This embodiment is preferred because it allows for perfect maneuverability of the scissors. The figure 13 illustrates a preferred embodiment in which the support lug 35 and the element 331, being a lug having a free end 332, originate in opposite portions of said closed contour 32. The figure 14 illustrates a preferred embodiment in which the eyelet 3 has several support lugs 35a and 35b. In addition, the projecting lug 331 is located opposite the support lug 35a.
