Scissors

Abstract

The present invention relates to a pair of scissors comprising first and second blades mounted for pivotal movement relative to one another about an axis of rotation, and an eyelet secured to the first blade, with an axis disposed between the eyelet and the first blade.

Description

[Technical field]

[0001] The present invention relates to the technical field of articulated objects, more particularly to the technical field of scissors, in particular scissors intended for cutting hair.

[0002] In the description herein, intervals described by the phrase "between [...] and [...]" are inclusive of the endpoints. For example, the interval "between 1 and 2" includes the two values ​​"1" and "2", as well as the set of values ​​strictly greater than 1 and strictly less than 2.

[0003] In the present description, the term "about" before a numerical value means that the value can be modified by plus or minus 10%. In the special case of numerical values ​​that are interval boundaries, the term "about" means that the lower limit can be decreased by 10% or the upper limit can be increased by 10%. It is also possible to remove the term "about" before a numerical value. [Background technology]

[0004] Scissors, particularly those known as hairdressing scissors, typically feature two attached blades that rotate relative to one another about an axis.

[0005] Each blade has a respective eyelet for attachment. An axle is disposed between the blade and its eyelet. Each eyelet allows the user to position one or more fingers to use the respective blade by pivoting them about the axle.

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

[0007] In the description herein, a "user" is a user of the scissors. This can include a hairdresser.

[0008] Hairdressing and beauty work requires a lot of scissors movement and position changes.

[0009] Users perform these movements most often by rotating and moving their wrist.

[0010] Such wrist movements and rotations are the cause of many musculoskeletal disorders (hereinafter "MSDs"), such as tendonitis, which can be particularly disruptive to professional work in hairdressing. These conditions are very common among hairdressers and hairdressers, who may be forced to cease professional activity due to these conditions.

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

[0012] Gripping the scissors is most often accomplished by engaging the thumb in one eyelet of the scissors and at least one finger in the other eyelet of the scissors.

[0013] The cutting action is primarily performed by the thumb, while the other fingers remain relatively motionless.

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

[0015] In particular, the position of the incision surface relative to the scalp can be either not influenced or only to a very small extent.

[0016] Thus, when using scissors, many of the extreme and potentially traumatic movements are performed by other joints, particularly the wrist joint.

[0017] In this regard, scissors users are particularly exposed to a number of health risks, including:

[0018] - the aforementioned MSDs related to the user's posture and movements, which are unpleasant, frequently repetitive, very frequent and lead to disabling bone and joint diseases.

[0019] - Cuts which in some cases may result in direct contamination, especially with regard to blood-borne diseases.

[0020] As mentioned above, depending on the position of the head and the location of the hair to be cut, positioning the scissors can be difficult, especially requiring variable wrist rotation, including extreme positions, which poses health challenges for the user.

[0021] These problems are further amplified if the user suffers from certain medical conditions, particularly osteoarthritis.

[0022] The prior art has proposed several approaches to improve the ergonomics of hairdressing scissors.

[0023] First, we tried to make scissors with prongs curved at right angles.

[0024] For example, WO 2002094512 (KIM) discloses scissors having prongs at right angles or substantially right angles.

[0025] US Patent Application No. 5,232,000 (CHIAVARAS) also states that scissors with right angle prongs are more ergonomic.

[0026] In practice, these scissors do not limit the risk and are not very ergonomic. Moreover, their wear, especially at the hinges, occurs prematurely due to the position of the eyelets.

[0027] Next, they attempted to create scissors with one or more hinges, which they believed would improve ergonomics.

[0028] Thus, US Patent Application No. 5,469,624 (BRENTON) discloses scissors with a thumb eyelet attached to a hinge perpendicular to the thumb temple, which can be disassembled and its size adapted to the user.US Patent Application No. 20050204569 (BRENTON) discloses scissors with an incomplete thumb eyelet attached to a hinge perpendicular to the thumb temple, which can be disassembled and its size adapted to the user.

[0029] Other claims with similar disclosures include U.S. Patent Application No. 20080172886 (DONG HO JUN), U.S. Patent Application No. 20100212165 (PARNAZZINI et al.) and International Publication No. 2007133567 (FOX).

[0030] U.S. Patent Application Publication No. 20050005456 (WANG et al.) discloses scissors with a thumb eyelet attached to a hinge located on an extension of the thumb fork.

[0031] Finally, WO 2014132279 (DE STEFANO) discloses scissors with two rotating eyelets, which are presented as allowing better ergonomics.

[0032] In reality, these solutions offer no added value to the user from a health point of view, and even worse, the hinges are free, which can cause rotations during cutting, complicating the user's work and maximizing the risk of cuts. [Prior art documents] [Patent documents]

[Patent Document 9] International Publication No. 2014132279 (DE STEFANO) Summary of the Invention [Problem to be solved by the invention]

[0034] There is a need for scissors with improved ergonomics that can reduce the risk of MSDs and improve a user's grip while reducing the risk of cuts. [Means for solving the problem]

[0035] The present invention is intended to address one or more of the shortcomings identified in the prior art.

[0036] The invention therefore relates to a pair of scissors 1, which comprises: a first blade 21 and a second blade 22 pivotally mounted relative to one another about an axis of rotation 91; an eyelet 3 attached to a first blade 21, the axis 91 being located between the eyelet 3 and the first blade 21, - the eyelet 3 defines a closed contour 32 surrounding the passage section 34, the eyelet 3 being characterized in that it comprises protruding elements 331, 333 which protrude inwardly from the passage section 34 relative to the closed contour according to an orthogonal projection on a cutting plane 92 perpendicular to the axis of rotation 91.

[0037] The scissors 1 according to the invention provide additional comfort and help to prevent injuries and muscle fatigue. One of the most important advantages of using the scissors 1 according to the invention is the reduction of muscle fatigue, especially for hairdressers. The scissors 1 according to the invention allow a more balanced distribution of pressure on the fingers, reducing strain on the muscles of the hand, wrist and forearm.

[0038] Another advantage is improved precision and control: the scissors 1 according to the invention provide a more comfortable and stable grip, which allows the user, in particular the hairdresser, to better control his movements, improve his precision and reduce the risk of trembling.

[0039] Use of scissors 1 according to the present invention can also help prevent musculoskeletal disorders such as tendonitis, epicondylitis, or joint pain. By reducing strain on the muscles, tendons, and nerves of the fingers, hands, and forearms, scissors 1 according to the present invention can help prevent these health problems.

[0040] Furthermore, the scissors 1 according to the invention improve comfort, especially for hairdressers who work with the scissors for long periods of time.

[0041] By reducing the risk of muscle strain and musculoskeletal disorders, the scissors 1 according to the invention can contribute to their overall well-being. In short, the use of the scissors 1 according to the invention can help to improve the performance and comfort of users, particularly hairdressers, while reducing the risk of injury and muscle fatigue.

[0042] It should be noted that in the context of elevation cutting, the scissors according to the invention are particularly advantageous. Indeed, during such cutting, the scissors are in the right hand and the comb in the left hand (for a right-handed person). When cutting, the right hand with the scissors is in a position parallel to the ground and 5 cm to 30 cm above the head. In this cutting position, the scissors according to the invention can be kept out of the way of the thumb and therefore less strain on the right wrist. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0044] In one embodiment, said scissors 1 are made of a rigid material, preferably a metal or a metal alloy, preferably selected from the group consisting of steel, stainless steel and titanium.

[0045] In one embodiment, the 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.

[0046] In one embodiment, the eyelet 3 is made of a rigid material, preferably a metal or a metal alloy, preferably selected from the group consisting of steel, stainless steel and titanium.

[0047] In one embodiment, the eyelet 3 comprises a rigid material, preferably a metal or an alloy of metals, preferably selected from the group consisting of steel, stainless steel and titanium.

[0048] In one embodiment, the scissors 1 are made from a single material, which in some cases is advantageous as it reduces wear and tear.

[0049] In one embodiment, the scissors 1 are constructed from a number of different materials, which in some cases may be advantageous as it allows for ease of manufacture.

[0050] For example, the material of the thumb eyelet 3 may be different from the material of the blades 21 and 22 .

[0051] This is particularly beneficial where the thumb eyelet is particularly difficult to manufacture: it may be appropriate to manufacture the thumb eyelet from a more ductile material than the blade.

[0052] In one mode of realisation, said scissors are scissors for hairdressing. This method of realisation is preferred in the hairdressing and beauty sector, where ergonomics are particularly important due to the repetition of certain movements.

[0053] In one embodiment, the eyelet 3 is attached 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 attached to a hinge or any other means that allows the eyelet to move relative to the lever 51. This makes the scissors more ergonomic.

[0054] In one embodiment, the scissors 1 are provided with a single hinge at the level of the axis of rotation 91 .

[0055] In one embodiment, the scissors 1 do not include any hinges other than the one present at the level of the axis of rotation 91 .

[0056] In one embodiment, the scissors 1 do not include a hinge at the height of the eyelets. In the construction method, the scissors 1 do not include a hinge at the height of two eyelets. This implementation method is preferred because it is beneficial for hairdressers who cut hair for long periods of time. With no hinges at the eyelets, tension is evenly distributed to the fingers, reducing fatigue and strain on the joints. It may also help prevent injuries from long-term use of the scissors. Furthermore, scissors without hinges at the eyelets can provide greater freedom of movement and control of cutting, allowing hairdressers to work more efficiently.

[0057] In one embodiment, scissors 1 are each constructed from a continuous piece of material.In one embodiment, scissors 1 are each constructed from a continuous piece of material without hinges.

[0058] In one embodiment, the length of the scissors is about 10 cm to about 20 cm, preferably about 12.5 cm to about 17.5 cm. Preferably, the length of the scissors is about 15 cm.

[0059] In one embodiment, the length of the end of the blade at the rotation axis 91 is about 5 cm to about 10 cm, preferably about 7.5 cm to about 12.5 cm.

[0060] In one embodiment, the length from the end of the eyelet to the rotation axis 91 is about 5 cm to about 10 cm, and preferably about 6 cm to about 8 cm.

[0061] In fact, levers 51 and 52 connect each of the two eyelets (including eyelet 3) to blades 21 and 22.

[0062] In one embodiment, lever 51 is straight. In one embodiment, lever 52 is straight. In one embodiment, levers 51 and 52 are straight.

[0063] Straight levers offer several advantages. First, their ergonomic design allows for a comfortable grip and reduced muscle fatigue during long cutting sessions. Straight levers also provide better stability and control, allowing for more accurate and cleaner cuts. Furthermore, scissors 1 according to the invention with straight levers are often lighter than models with curved levers, allowing for longer periods of use without pain and strain on the wrist and fingers.

[0064] In one embodiment, said eyelet 3 is a thumb eyelet, meaning that it is intended to be occupied by the user's thumb.

[0065] In one embodiment, the eyelet 3 and the first blade 21 are integral.

[0066] In one embodiment, said scissors 1 are straight scissors.

[0067] In one embodiment, said scissors 1 are off-axis scissors.

[0068] In one embodiment, the scissors 1 are sculptor scissors.

[0069] In one embodiment, said scissors 1 are micro-serrated scissors.

[0070] In one embodiment, said scissors 1 are right-handed scissors, since most users are right-handed this mode of realization is preferred.

[0071] In one embodiment, the scissors 1 are left-handed scissors.

[0072] For obvious ergonomic reasons, the suitability of the scissors for right-handed and left-handed people is important. In both cases, the thumb is intended to contact the eyelet 3 of the first blade 21.

[0073] When handling the scissors 1, the user's thumb contacts the eyelet 3 and the protruding elements 331, 333 ensure that the thumb does not penetrate too deeply into the eyelet 3. Problematic wrist movements can therefore be transmitted to the thumb, thus enabling the user to avoid MSDs and their consequences.

[0074] In summary, the closed contour allows the user to provide an actual support point for the thumb, allowing the user to transmit complex and potentially traumatic movements directly from the wrist to the fingers, especially the thumb.

[0075] 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 points of a closed contour 32 .

[0076] In one embodiment, said element is a strip 333 connecting two positions of a closed contour.

[0077] In one embodiment, said element is a lug with a free end 331. This implementation is preferred as it allows for support of the thumb whilst saving material.

[0078] In one embodiment, said free end is rectangular in cross section.

[0079] In one embodiment, said free end is pointed in shape.

[0080] In one embodiment, the scissors 1 are characterized in that said elements 331 protrude into the passage section 34 over a length of at least about 5 mm.

[0081] In one embodiment, the element 331 protrudes into the passage section 34 a length of at least about 10 millimeters.

[0082] In one embodiment, the element 331 protrudes into the passage section a length between about 5 millimeters and about 30 millimeters.

[0083] In one embodiment, the element 331 protrudes into the passage section a length between about 10 millimeters and about 25 millimeters.

[0084] In one embodiment, the element 331 protrudes into the passage section a length of about 15 millimeters.

[0085] In one embodiment, the scissors 1 are characterized in that said element is a protruding lug 331 having a free end 332 of pointed shape.

[0086] In one embodiment, the scissors 1 are characterized in that the closed contour 32 comprises a portion 321 which is included in the cutting surface 92 and a portion 322 which is offset relative to the cutting surface 92 such that the closed contour 32 defines a notch 323 in the cutting surface 92.

[0087] This method of implementation is particularly preferred. Indeed, the cutout 323 created allows the thumb to be relatively free from its movements, and in particular with regard to the orientation of the scissors induced by the thumb. The combination of said protruding elements 331, 333, which protrude inwards from the passage section 34 with respect to a closed contour on the one hand, and the cutout 323 on the other hand, allows the thumb to have the greatest influence on the position of the scissors and thus transmits the greatest movement from the wrist and other joints to the thumb of the user.

[0088] In one embodiment, the offset portion extends relative to cutting plane 92 at least 1 cm.

[0089] In one embodiment, the offset portion extends relative to cutting surface 92 at least 2 cm.

[0090] In one embodiment, the offset portion is offset at an angle A of between about 90° and about 170°.

[0091] In one embodiment, the offset portion is offset at an angle A of about 100° to about 160°.

[0092] In one embodiment, the offset portion is offset at an angle A of about 110° to about 150°.

[0093] In one embodiment, the offset portion is offset at an angle A of about 120° to about 150°.

[0094] In one embodiment, the offset portion is offset at an angle A of about 125° to about 145°.

[0095] In one embodiment, the offset portion is offset at an angle A of about 135° to about 140°.

[0096] In one embodiment, the offset portion is offset at an angle A of about 138°. The closer angle A is to 138°, the more ergonomic the scissors 1 will be.

[0097] In one embodiment, the scissors 1 are characterized in that said cutouts 323 are arranged on the outer edges of the closed contour 32 .

[0098] This method of implementation is particularly preferred, as it allows the thumb to maintain both a good ability to press the lever 51 while offering a large number of position possibilities corresponding to different orientations of the scissors during haircutting.

[0099] In one embodiment, the scissors 1 are characterized in that the orthogonal projection of said notch 323 on the cutting plane 92 covers at least an angular sector [40°, 140°] around point O with respect to vector OP, point O being defined as the geometric center of the orthogonal projection of the closed contour 32 on the cutting plane 92 and point P being defined as the intersection between the cutting plane 92 and the rotation axis 91.

[0100] In one embodiment, the scissors 1 are characterized in that the orthogonal projection of said notch 323 on the cutting plane 92 covers at least an angular sector [50°, 130°] around point O with respect to vector OP, point O being defined as the geometric center of the orthogonal projection of the closed contour 32 on the cutting plane 92 and point P being defined as the intersection between the cutting plane 92 and the rotation axis 91.

[0101] In one embodiment, the scissors 1 are characterized in that the orthogonal projection of said notch 323 on the cutting plane 92 covers at least an angular sector [60°, 120°] around point O with respect to vector OP, point O being defined as the geometric center of the orthogonal projection of the closed contour 32 on the cutting plane 92 and point P being defined as the intersection between the cutting plane 92 and the rotation axis 91.

[0102] In one embodiment, the scissors 1 are characterized in that the orthogonal projection of said notch 323 on the cutting plane 92 covers at least an angular sector [70°, 110°] around point O with respect to vector OP, point O being defined as the geometric center of the orthogonal projection of the closed contour 32 on the cutting plane 92 and point P being defined as the intersection between the cutting plane 92 and the rotation axis 91.

[0103] In one embodiment, the scissors 1 are characterized in that the orthogonal projection of said notch 323 on the cutting plane 92 covers at least an angular sector [80°, 100°] around point O with respect to vector OP, point O being defined as the geometric center of the orthogonal projection of the closed contour 32 on the cutting plane 92 and point P being defined as the intersection between the cutting plane 92 and the rotation axis 91.

[0104] In one embodiment, the scissors 1 are characterized in that the orthogonal projection of said notch 323 on the cutting plane 92 covers at least an angular sector [85°, 95°] around point O with respect to vector OP, point O being defined as the geometric center of the orthogonal projection of the closed contour 32 on the cutting plane 92 and point P being defined as the intersection between the cutting plane 92 and the rotation axis 91.

[0105] In one embodiment, the scissors 1 also include support lugs 35 that project inwardly from the passage section 34 relative to the closed contour 32 .

[0106] The presence of support lugs 35 is particularly desirable as they allow the scissors to be opened more easily above the thumbs.

[0107] In a particularly preferred embodiment, the notch 323 is present and the scissors also include a support lug 35 which projects inwardly from the passage section 34 relative to the closed contour 32 and is arranged adjacent to said notch 323. In the latter case, there is a real synergy between the notch 323, which allows the thumb freedom, and the support lug 35, which allows the scissors to maintain ease of opening between the two approaches of the levers 51 and 52, i.e. between the two cutting actions.

[0108] In a particularly preferred embodiment, the support lugs 35 also protrude from the cutting surface 92. Figure 12 illustrates this particular embodiment, which is preferred as it allows for maximum maneuverability of the scissors.

[0109] In a particularly preferred embodiment, the support lug 35 and the element 331 (e.g. the lug with the free end 332) originate from opposite parts of the closed contour 32. Figure 13 shows this particular embodiment, which is preferred as it allows the thumb to be guided between said support lug 35 and said element 331. The thumb is exactly centered between these two elements, which is advantageous.

[0110] In one embodiment, the support lugs 35 are at least about 1 mm in length, preferably at least about 2 mm, preferably at least about 3 mm, preferably at least about 4 mm in length.

[0111] In one embodiment, the support lugs 35 are about 1 mm long, preferably about 2 mm long, preferably about 3 mm long, preferably about 4 mm long.

[0112] In one embodiment, the scissors 1 include two support lugs 35a and 35b.

[0113] In one embodiment, the scissors 1 are provided with two support lugs 35a and 35b, each protruding inwardly 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.

[0114] The presence of several support lugs 35 is particularly desirable as this distributes the load and reduces friction on the skin of the thumb, allowing the scissors to be opened more easily over the top of the thumb.

[0115] In one embodiment, the at least one support lug 35 and the element 331 originate within the same portion of the closed contour 32 .

[0116] In one embodiment, the scissors 1 are characterized in that the offset portion 322 and said projecting element 331 are offset to the same side relative to the cutting plane 92 .

[0117] In one embodiment, the scissors 1 are characterized in that the offset portion 322 and said projecting element 331 are located on the same side relative to the cutting surface 92 .

[0118] In one embodiment, the scissors 1 are characterized in that said eyelet 3 is removably attached to the first blade 21 by a fixed interface 6, which allows the eyelet 3 to be attached in several angular positions around an axis 93 perpendicular to the rotation axis 91 of the first blade 21 and the second blade 22.

[0119] In one embodiment, the number of said angular positions is 12 and are therefore spaced apart by 30°.

[0120] In one embodiment, the number of said angular positions is 12 and are therefore 30° apart since 30×12 equals 360° (a full rotation).

[0121] In one embodiment, the scissors 1 are characterized in that said element is offset with respect to the first blade 21 in a direction corresponding to the axis of rotation.

[0122] The present invention also relates to the use of scissors 1 according to the invention for reducing the risk of occurrence of MSD.

[0123] The invention also relates to scissors 1 according to the invention, intended to be used for reducing the risk of occurrence of MSD.

[0124] The present invention also encompasses the variants presented herein. Those skilled in the art will understand that the features of each of these variants can be combined, but do not constitute intermediate generalizations.

[0125] Other characteristics and advantages of the invention will become apparent from the following description, given by way of indication and in no way limiting, with reference to the accompanying drawings, in which:

[0126] FIG. 1 shows scissors 1 for performing hair styling according to the invention, comprising a first blade 21 and a second blade 22 pivoted relative to each other about a rotation axis 91. A cutting surface 92 and levers 51 and 52 are also shown. These levers 51, 52 are straight. An eyelet 3 is shown, intended for contact with the thumb and integral with the first blade 21. More precisely, the eyelet 3 defines a closed contour 32 surrounding a passage section 34 and comprises, according to an orthogonal projection on the cutting surface 92 perpendicular to the rotation axis 91, an element 331 which is a lug having a free end 332 which projects inwardly from the passage section 34 relative to the closed contour. A portion 322 of the eyelet 3 is offset from the cutting surface 92. A support lug 35 is shown which projects inwardly from the passage section 34 from the closed contour 32, with a notch 323 arranged on the outer lateral edge of the closed contour 32 and adjacent to said notch 323. The protruding support lugs 35 allow the thumbs to easily spread apart the levers 51, 52, thus providing a virtual fulcrum.

[0127] Figure 2 shows the same scissors as shown in Figure 1, seen from a different angle. The explanation of Figure 1, which corresponds to the numbers present in Figures 1 and 2, is therefore applicable to this Figure 2. The eyelet 4, which corresponds to the lever 52, as well as its passage portion 44 are shown. Furthermore, the orthogonal projection of said notch 323 on the cutting plane 92 (not shown) covers a certain angular sector around point O with respect to vector OP, point O being defined as the geometric center of the orthogonal projection of the closed contour 32 on the cutting plane 92, and point P being defined as the intersection between the cutting plane 92 and the axis of rotation 91.

[0128] Figure 3 shows the same scissors as shown in Figures 1 and 2, but from a different angle. Therefore, the descriptions of Figures 1 and 2 corresponding to the numbers present in Figures 1 and / or 2 and 3 are applicable to this Figure 3.

[0129] Figure 4 shows the same scissors as shown in Figures 1 and 2, but from a different angle. Thus, the descriptions of Figures 1 and 2 corresponding to the numbers present in Figures 1 and / or 2 and 4 are applicable to this Figure 4. In Figure 4, axis 91 is vertical.

[0130] 5 is a detailed view of the eyelet 3 corresponding to the lever 51. The passage section 34 relative to the closed contour 32 is shown.
