    CANTILÉVER COMB FOR PROTECTION OF APPLIANCE CARTRIDGE Shave or shave
    FIELD OF THE INVENTION 5 The present invention relates to shaving or shaving blade sets, and more particularly, to shaving or shaving blade sets that have a cantilever comb protection to facilitate the lifting, orientation and passage of hairs. hair for an IO blade for an efficient and effective shaving or shaving.
    BACKGROUND OF THE INVENTION In general, a cartridge or blade unit of a safety razor or shaver has at least "a razor-sharp blade that is moved along the surface of the skin being shaved or shaved with a razor. head to which the cartridge is attached The cartridge can be removably mounted on the handle to allow c) cartridge to be replaced with a new cartridge when blade efficiency reaches an unsatistatory level, or that the cartridge can be permanently attached to the cable with the intention that the entire razor or shaver will be discarded when the razor or blades lose their thread. Shaver or epilator cartridges usually include a protection that comes in contact with the skin in front of the razor (s) and a cap for contact with the skin behind the blade (s) during shaving or shaving. The cap and protection can assist in establishing the so-called "shaving or shaving geometry", is to is, the parameters that. determines the orientation of the blade and the position in relation to the skin during shaving or epilation, which, in turn, has a strong influence on the performance of shaving or epilation and the effectiveness of the razor 5 or shaving. The protection can be generally rigid, for example integrally formed with a chassis or a platform structure that serves as support for the blades.
    The protections are present in many shavers or shavers and are designed to stretch the skin; however, these protections also have a propensity to press hair against the skin. The interaction of these protections with the hair is similar to the roll of a ballast cylinder on the grass just before cutting the grass with the blade of a lawn mower. The grass, similar to c) hair on the skin, cannot be cut in a way effective and efficient if it is not, in general, oriented. perpendicular to the blade.
    The standard shaving or shaving guards are able to cut the short hairs more effectively, since the short hairs are usually hard and usually oriented perpendicular to the blade. Hair growth can vary depending on the individual, as well as the body area being shaved or shaved. The typically short hair is characterized by a growth of approximately twenty-four hours. As hair grows longer, it tends to bend and stay flat against the skin's surface in an orientation that is parallel to the skin's surface. Standard razors or shavers are less effective for cutting longer hairs because the blade (or blades) has a tendency to stick in layers or cut hairs at an angle. The blade does not consistently cut the longest hairs close to the skin surface due to the generally parallel orientation of the hair. Some hairs can remain flat so that the razor blade or epilate pastes on them without cutting them. The user commonly has to shave or shave the same area repeatedly to cut the hairs that have not been cut or that have not been cut close enough to the skin surface, resulting in increased skin irritation.
    SUMMARY OF THE INVENTION + In one aspect, the invention has, in general, a set of razor or shaving razor featuring a single blade unit with at least one razor and a protective bar positioned in front of the razor. A cantile protector is positioned in front of the blade unit and defines a gap between the protection bar and the cantilever protection. The cantilever guard has a plurality of spaced fingers extending transversely to the blade. The fingers have a wedge-shaped cross section in a direction transverse to the blades and are movable in relation to the protective pad between a first position and a second position during a shaving or waxing course.
    In another aspect, the invention generally presents a set of shaving or waxing lamina having a blade unit sized to receive at least one blade and a cantilever tip positioned in front of the blade unit. The cantilever guard has a plurality of spaced wedge-shaped fingers, each with a fixed end attached to the blade unit 5 and a free end. The fingers taper from a greater thickness at the fixed end to a lesser thickness at the free end to facilitate the movement of the fingers between a first position and a second position during a shaving or waxing course.
    10 If desired, particular modalities may optionally include a protective bar with a slot positioned between the blade and the cantilever guard.
    Particular modalities can also. optionally include a sliding member that surrounds the blade unit b and the cantile shield.

    DETAILED DESCRIPTION OF THE INVENTION Referring to figure 1, an embodiment of the present invention is shown illustrating a shaving or shaving blade set 10 that includes a blade unit 12, a sliding member 14 and a cantilever shield 20. One or more blades 22 can be mounted on. blade unit 12. Blades 22 can be attached to blade unit 12 with a pair of clamps 16; however, other mounting / fastening methods known to elements skilled in the art can be used including, but not limited to, wire wrapping, cold forming, hot fastening, molding by insertion element and adhesives.
    Although five blades 22 are shown, it is understood that blade unit 12 may have more or less blades 22. In certain embodiments, blade unit 12 may include a guard bar 18 positioned in front of blades 22. A guardrail 18 may be a solid member or may have a plurality of projections 15 that define a series of slots 17 that are transversal to the blades 22. The guardrail 18, as shown in Figure 1, has a section rectangular genericanente transversal, however several shapes f3 in cross section are possible, as circles, squares, triangles, ovals or any combination thereof.
    The blade unit 12 can be molded by injection from a semi-rigid polymeric material, for example, Noryl '"(a polyphenylene oxide (PPO) and polystyrene structure developed by General Electric Plastics, currently SABIC Innovative Plastics). Blade unit 12 can be molded from other semi-rigid polymeric materials having a Shore A hardness of about 50, 60 or 70 to about 90, 110 or 120, such as polypropylene, acrylonitrile-butadiene-styrene, polystyrene of high.
    impact, or any combination thereof. A "semi-rigid material can allow the Blade 12 unit to maintain a consistent geometry during shaving or shaving. Blade 12 unit can be of sufficient hardness so that it does not bend or flex under co ' normal shaving or shaving conditions, which may adversely affect the shaving or shaving geometry of the shaving or shaving blade set 10.
    The slide member 14 can be positioned behind the blade unit 12 and in front of the cantilever guard 20. In certain embodiments, the slide member 14 can be a ring surrounding the blade unit 12, the guard bar 18 and the protection of the cantilever 20, so that lubrication is provided both in front of and behind the blades 22 during shaving or epilation for greater comfort. In other embodiments, the slide rrLemember 14 can be positioned just behind the blades
    2'2, But not in front of blades 22. The "sliding member 14 can have a smooth surface and can provide lubrication to the skin by releasing a shaving aid or waxing in front of and / or behind the wool blade unit 12.
    In certain styles, the sliding member 14 may include a shaving or waxing aid such as a soap, for example, a spilled extruded soap.
    Soap-based compositions can be modified to increase the toughness, wear resistance, lubricity and / or skin moistening and conditioning properties of the desiizing member 14. Other materials can be used for the sliding member 14 as a material that comprises a mixture of a hydrophobic material and a. water-leachable hydrophilic polymeric material, as is known in the art and described in U.S. Patent No.
    5,113,585 and 5,454,164. The sliding edge 14 may have sufficient wear resistance so that the Sliding member 14 lasts for the intended life of the shaving or shaving blade set 10 (for example, the blades become very loose). In other embodiments, the sliding member 14 can be injection molded from semi-rigid polymeric materials that do not wear out under normal shaving or waxing conditions, such as Noryl "(a mixture of polyphenylene oxide (PPO) and polystyrene developed by General Electric Plastics, currently SABIC Innovative PLastícs.) The sliding member 14 can be molded from other semi-rigid polymeric materials with a Shore A hardness of about 50, 60 or 70 at around 90, 11'0 o ' u 120, such as, but not limited to, polypropyl-ene, acrylonitrile-butadiene-styrene (ABS), polyethylene fluorine (PTFE), high density polyethylene (HPDE), acetal, nylon, high impact polystyrene or any The polymeric material can also be filled with materials such as silicone, molide disulfide or other lubricating agents known for elements skilled in the art to reduce friction against the surface of the skin. .
    The protection of the cantilever 20 can extend parallel to the Blades 22 and can be positioned in front of the protection bar 18 and behind the sliding member 14. The "protection of the cantiiéver 20 can be used alone or in combination with the protection bar 18 (for example, the cantilever guard 20 can be positioned directly in front of the guard bar 18 or. Directly in front of the blades 22). The cantij-éver guard 20 can also be used alone or in combination with the desired member. -ing 14.
    The cantilever guard 20 may have a plurality of spaced fingers 25 extending transversely to the blades
    22. The fingers 25 can facilitate the orientation or lifting of the hair in an upward direction away from the skin surface. The fingers 25 can also facilitate the passage of hair to the blades 22 in a more vertical position, which can provide a more efficient and precise cut of the hair during a shaving or waxing course. In certain modes, fingers 25 can be configured to lift and guide the longest hairs to the protection bar
    18, which can also line up and pass the hair over the blades 22 for a closer and more comfortable shave.
    As will be explained in more detail below, the fingers 25 can deflect transversely in relation to the blades 22 5 to follow the contours of the skin and facilitate the lifting of hair from the skin surface. 08 fingers 5 can have a top surface 29 which is flat to facilitate the engagement and lifting of hair. The fingers 25 may extend over the entire length of the cantilever 20 protection, or they may extend over only certain sections of the cantilever 20 protection, such as in the middle or at the ends. In certain embodiments, the plurality of fingers 25 may extend to less than one length of the blades 22. For example, the plurality of fingers 25 may extend from about 50%, 55% or 60% to about 75%, 85 % or 95% of the length of the blades 22.
    The protection of the cantilever 20 (and / or the fingers 25) can be molded from a resilient material to facilitate the flexion of the fingers 25 in a direction transversal to the blades 22. The resilient material can also optimize the tactile sensation against the skin and provide improved skin stretch compared to stiffer materials.
    The properties of the protective material of the cantilever 20 can facilitate fingers 25 to deflect under normal shaving or waxing forces and lift hairs that may be horizontal against the skin surface. The cantilever guard 20 and / or fingers 25 can be manufactured from a softer material than the blade unit 12. For example, the cantilever guard
    20 and / or fingers 25 can have a Shore A hardness of about
    20, 30 or 40 to about 50, 60 or 70. The protection of the cantilever 20 and / or fingers 25 can be molded from
    5. Thermoplastic elastomers (TPEs) or rubbers; examples may include, but are not limited to, silicones, natural rubber, butyl rubber, nitrile rubber, styrene and butadiene rubber, styrene butadiene styrene TPES
    (SBS), ethylene butadiene styrene (SEBS) TPES,
    Polyester TPES, Polyamide TPES, Polyurethane TPEs,
    Polyolefin-based TPES and mixtures of any of these
    TPES (for example, polyester / SEBS mixture). In certain
    "Iriodality3, the protection of canti ether 20 can comprise the thermoplastic elastomer compound Dynaflex® G6730 from GLS
    Corp. (a PolyOne company). The protection of the cantilever 20 and / or the fingers 25 may comprise other resilient materials that provide sufficient flexibility for the flexion of the fingers 25. Such materials may have an elongation at break of about 100%, 300% or 500% until about
    · 20 700%, 800% or 1000% (ASTM D412-Oie C, 2 h, 23 ° C). If the elongation of the material of the fingers 25 is too great, the fingers 25 may not provide sufficient strength to lift the hair from the surface of the skin, or the fingers 25 may roll or bend backwards on themselves.
    A material with greater elongation (or lower Shore A hardness) can improve the stretch of the skin and provide a more pleasant tactile sensation against the user's skin during shaving, as well as optimizing the ability of the fingers 25 to lift the fingers. hair. A material exhibiting greater elongation (or less Shore A hardness) can also be chosen to aid in masking the unpleasant sensation of the harder material 5 of blade unit 12 and blades 22 against the user's skin during c) shaving or shaving. action- Alternatively, the protection of the cantilever 20 and / or fingers 25 can comprise a polymeric material having a Shore A hardness of about 70 to about 120. Under certain styles, the protection of the cantiíverver 20 and / or the fingers 25 can be made of stiffer materials (for example, of lower elongation) or harder that include a "live" joint to assist in deflection of the fingers 25.
    With reference to figure 2, in certain embodiments, the shaving or shaving blade set 10 may be part of a shaving or shaving system 28 in which the shaving or shaving blade set 10 is associated with the handle 30. the shaving or epilation blade set 10 can be permanently attached to the handle 30 or can be detachably mounted and replaced as needed. The shaving or epilation blade set 10 can be fixedly or swiveled to the handle 30 to follow the contours of the skin during shaving or epilation. The shaving or shaving blade set 10 may also include an interconnecting element 34 to which the shaving or shaving blade set 10 is pivotally mounted around an axis of the pivot. A release button 32 can be provided on the cable
    30 to facilitate removal of the shaving or epilation blade set 10 from the handle 30.
    With reference to figure 3, a partial cross-sectional view of the razor blade or 5 epilation set 10 is shown, taken generally along line 3- 3 in figure 1— The cross section in figure 3 is taken in one direction transversal to the blades 21. The blades 22 can have a cutting edge 21 that defines a plane of the blade 31 that is tangent to two or ends of the cutting edges 21. For example, the blade 22 closest to the protection bar 18 and the Blade 22 ends farther from the protection bar 18 can define and be tangent to the plane of the blade. Additional blades 22 "can be positioned above, below or in the plane of the '31 blade. Each of the Blades 22 can be slid on a blade holder 23. Blades 22 and blade holders 23 can be spaced from the guard bar 18 and fingers 25. The fingers 25 can deflect independently of the blade unit 12 (for example, in relation to the guard bar 18, the blade holders 23 and / or the blades 22) to facilitate orientation
    2.0 of the pelDs in an upward direction away from the skin surface to allow the blades 22 to cut the hair more evenly and close to the skin surface.
    The fingers 25 can have a germillary length of about 1.0 nm, 2.0 mm or 3.0 mm to about 3.5 mm, 4.0 mm or 5.0 mm. Each of the fingers 25 may have a fixed end 40 which is attached to the blade unit 12 and a Free end 42 which is spaced from the sliding member 14. In certain embodiments, the fixed end 40 can be attached to the bar
    'protection' 18 and 'the blade unit 1'2 could be separated from the ".'-.! i" air] razor blade or hair removal 10. The protection, C.antiléver 20 can be attached to the blade unit 12 and / or the protective magnet by molding the insertion element or 5 mQ'1direction by cojection. Other mechanical or chemical assembly / fixation methods known to those skilled in the art may also be used to attach the blade unit to the cantilever protection 20, such as adhesives, wire wrapping or mechanical closures. The fixed end 40 can be supported by the blade unit 12 and the free end 42 can be unsupported (for example, by the Magnet unit 12 or the sliding member 14) to facilitate flexing of the fingers 25 under the forces of normal shaving. A portion. significant number of fingers 2 "can be unsupported, for example, the unsupported length of fingers 25 can be from about 50%, 60% or 70% to about 75%, 85% or 95% of a .length general of fingers 25. Fingers 25 can have an unsupported length L2 of about 0, 50 mm, 1.0 mm or 1.50 mm to about 2.5 mm, 3.5 mm or 4.5 rrun .
    The free end 42 may have a tip 26 with a radius of about 0.1 mm, 0.15 mm or 0.2 mm at about 0.3 mm, 0.4 mm or 0.5 mm. Tip 26 can be defined as the forwardmost portion of fingers 25 (for example, closest to the sliding member 14). The tip 26 can be positioned at or below the plane 27 of the top surface 29 of the fingers 25. In certain embodiments, the surface of the top 29 of the fingers can extend along the plane of the blade 31, so that c) radius of the tip 26 is also positioned below the plane of blade 31. In other circumstances, tip 26 can be positioned on or above the plane of blade 31. The top surface 29 can be leveled or can decline from fixed end 40 to end 5 Free 42 to improve the ability of fingers 25 to hook and lift hair.
    In certain embodiments, the fingers 25 may have a curved cross-section (for example, a d-shape, and a triangular cross-section) that is transverse to the blades 21, so that the fingers 25 narrow to a greater thickness "tj "at the fixed end 40 to a lesser thickness" t2 "at the free end 42. In certain embodiments, t2 can be "about 0.25 mm, 0.5 mm, or 0.75 mm to about 1.75 mm, 2.0 mm or 2.25 mm and tj can be about 1.0 mm, 1.5 mnt or 1.75 mm at about 2.0 rrun, 3.0 mm or 4.0 mrrt.The wedge-shaped geometry can facilitate flexing the fingers 25 and lifting the hair from the surface of the skin during shaving or epilation.Fingers 25 may have an angle of funnel Otj which is defined by the top surface 29 and a bottom surface 44 of fingers 25. The angle of taper qi can be about 10 degrees, 15 degrees or 2'0 degrees to about 30 degrees, 40 degrees or 50 degrees to facilitate and control finger deflection 25.
    Referring to Figure 4, a partial top pIant view of the shaving or epilation blade assembly 10 is shown. In certain embodiments, the cantilever 20 protection and / or the fingers 25 can be separated from the projections 15 and / or the protection bar 18 to define a gap
    45 with a distance Cij of about 0.5 mm, 0.75 mm or 1.0 mm to about 1.5 mm, 2.0 mm or 2.5 mm.
    The spacing between the protection bar 18 (and / or the projections 15) and the protection of the cantilever 20 (and / or fingers 25) can facilitate the
    5 release of any hair that may be trapped under the fingers 25 during shaving or epilation.
    In certain embodiments, the projections 15 of the protection bar 18 can be displaced from the fingers 25 of the cantilever protection 20. The projections 15 can align any hair that has escaped from the fingers 25. The 3 fingers 25 can be spaced to define an open slot 46 having a width Wj of about 0.5 mm, 1.0 mm or 1.5 mm to about 2.0 mm, 3.0 mm
    'or 4.0 mm to facilitate the washing of the shaving or shaving blade set 10. The open slot 46 can also provide unobstructed passage of hair to the protection bar 18 and / or the blades 22. The fingers 25 can have a W2 width of about 0.5 mm, 1.0 mm c) ü 1.5 mm at approximately
    2.0 mm, 3.0 mm or 4.0 mm.
    The dimensions of the fingers 25 can prevent the fingers 25 from tipping back on themselves or protruding during shaving or epilation.
    If fingers 25 extend or bend backwards during shaving or epilation, then Delos could not be properly lifted and fingers 25 could feel uncomfortable against the skin surface during shaving or epilation.
    The sliding groove 14 can be positioned in front of the cantilever guard 20 so that the fingers 25 are spaced from the sliding member 14 to define a gap 47 with a distance d2 of about
    0.5 mm, 1.0 mm or 2.0 mm to about 3.0 mm, 4.0 mm or 5.0 mm.
    The gap 47 can allow any hair that is trapped under the sliding member 14 to be released and engaged by the protection of the cantilever 20. In other embodiments, the sliding member 14 can be located behind the blades 22 and / or laterally to the blades 22 and / or the cantilever 20 protection (for example, there may be no other component in front of the cantilever 20 protection).
    During a shaving or waxing course, the sliding member 14 can apply the shaving aid or epilation to the skin in front of the cantij-éver protection 20.
    Alternatively, the sliding member 14 may not deposit a shaving or shaving aid on the skin surface. As the hair passes from the sliding edge 14 for the protection of the cantilever 20, the span á7 can expose the hair to the fingers 25. The fingers 25 of the protection of the cantilever 20 engage c) the hair and deflect in a transverse direction to the blades 22. The fingers 25 can deflect independently of each other to facilitate the lifting of hair according to the shaving or epilation blade set 10 accompanying the contours of the skin during shaving or epilation. The fingers 25 can guide the hair in an upward direction away from the skin surface and pass it on to the protection bar 18 (or directly to the blades 22). According to the set of 1 shaving or shaving blade 10 slides across the surface of the skin, the surface of the top 29 of the fingers 25 can stretch the skin to reduce the bulging of the skin (which commonly leads to notches and cuts). Some hair may not engage your fingers
    25, however they can pass unobstructed through slits 46 and to the protection bar 18. Slits 17 and projections 15 can further align the hairs to be cut by Blade 22. The gap 45 between the protection bar 18 and the protection 5 of the cantilever 20 may allow the hair to break free or rise upward from the skin surface just before the hair is cut by the blade 22.
    With reference to figure 5, a schematic diagram representing the fingers 25 of the protection of the 10 cantilever 20 is shown. The fingers 25 È) can be movable between a first position 52 and a second position 62. In the first position 52, the plurality of spaced fingers 25 may have a longitudinal axis 50 that extends across the blade unit 12. The fingers 25 can be unloaded in the first position 52 so that the fingers 25 are not curved in relation to the Blade 20 unit. During shaving or shaving, the force of the shaving or shaving blade assembly 10 against the skin surface can apply a load P which causes the fingers 25 to bend resulting in the second position 62. In the second position 62 (for example, during shaving or shaving), the fingers 25 may have a longitudinal axis 60 which is curved at an angle in relative to the longitudinal axis 50 (pm: example, below the longitudinal axis 50). A deflection angle á2 of. longitudinal axis 60 of the fingers 25 relative to the longitudinal axis 50 (and / or the Iminin unit 12) can be about 10 degrees, 15 degrees or 20 degrees to about 25 degrees, 30 degrees or 40 degrees. The applied load can cause the fingers 25 to bend in a distance of about 0.1 mm, 0.5 mm or 1.0 mm to about 2.0 mm, 3.0 mm or 4.0 mm. The fingers 25 can engage the hair and lift the hair upwards as the applied load changes (for example, 5 the load is removed or decreased). The force required for the applied load to bend fingers 25 through distance d3 may vary depending on the location along the length of the finger 25, the load P applied, as well as the geometry and dimensions of the fingers 25. The width W2, the non- supported L2 and the thickness t2 of the fingers 25 can all vary to increase or decrease the force required to bend the fingers 25. For example, a particular modality of cantilever protection 20 that can provide sufficient flexibility may include the fingers 25 molded from an elastomer having a Shore A hardness of about 50 to 70 and may have a triangular cross section with an overall length L1 of about 3.6 mm, an unsupported length j2 of about 2.8 mm, tapering angle of about 25 degrees, a wide Zo W2 of about 1.0 mm, a thickness tj of about 3.0 mm and a thickness t2 of about 0.25 mm.
    With reference to figures 6A to 6F, the fingers 25 can have several different geometries of cross-section and tip configurations to facilitate the lifting of the skin hair and to improve the tactile sensation during shaving or waxing. For example, figure 6A shows a finger 25a showing a point 26a that reaches a point and figure 6B shows a finger 25b showing a bulbous tip 26b. The bulbous tip 26b can be positioned below a plane 27b that extends over a surface of the top 29b of the finger 25b. The finger 25a may be more efficient in raising hair and the finger 25b may provide the user with a more pleasant tactile sensation during shaving or shaving while still providing the benefit of raising hair. Figure 6C illustrates a finger 25c which is similar to finger 25a, except that finger 25C may have a cross section in "J" or "L" shape. The "J" or "L" shaped cross section of the fingers 25c can easily facilitate the deflection of the fingers 25 compared to the finger 25a. Figure 6D illustrates a wedge-shaped finger 25d that has a blunt tip 26d. In all of the modalities discussed, the top surface 29 may be above, below, or in the plane of the blade 31. In certain embodiments, a finger 25e may be have an angled top surface 29e (for example, declines from a tip 26e to a fixed end 40e). The finger 25e may have a portion that lies above a plane of the blade 31e (for example, the tip 26e and / or the free end 42e) and a portion below the plane of the blade 31e (for example, a fixed end 40e) - Alternatively, a finger 25f may have one, the angled top surface 29f which tilts from a tip 26f to a fixed end 40f The tip 26f and the free end 42f may be below the plane of the blade 3f and the fixed end 40f may be above the plane of the blade 31f.
