    Description of Embodiments of the Invention [048] Figure 1A illustrates a wet shaver or shaver 10 comprising a shaver or shaver handle 12, a shaving or waxing cartridge 14 and a protective cover 15 that can cover the shaving cartridge. shaving or shaving 14 as shown in Figure 1C and thus forms a shaving or shaving assembly.
    [049] The shaving or shaving cartridge 14 is provided with one or more shaving or shaving blades 16 that can be mobile or fixed in the shaving or shaving cartridge housing 14. For example, as shown in Figures 1A and 1B, the shaving or shaving cartridge 14 is provided with four shaving or shaving blades 16, but the invention is not limited to said amount of shaving or shaving blades.
    [050] As is well known, the shaving or epilation cartridge 14 can also be provided with a protection bar 19 and / or with a lubricating tape 21.
    [051] The shaving or waxing cartridge 14 is preferably a disposable shaving or waxing cartridge and
    Petition 870190137366, of 12/20/2019, p. 21/97
    11/34 includes a front face 14A that has one or many blades 16 exposed therein, and a rear face 14B that can be connected to the razor or shaver handle 12 as illustrated in Figures 1A, 1B and 1C by members of connection 28.
    [052] As illustrated in the Figures, the razor or shaver handle 12 has an elongated handle body 18 that extends in a longitudinal direction L between a front end 18A and a rear end 18B. The longitudinal direction L can be curved and / or include one or more straight portions. The handle body 18 has an upper face 18C opposite to a lower face 18D.
    [053] The protective cover 15 can cover the shaving or epilation cartridge 14, being loosely attached to the last one. Thus, the shaving or shaving cartridge 14 can be covered or uncovered with the protective cover 15. The protective cover 15 can be slid on the shaving or hair removal cartridge 14 as shown in Figures 1A and 1B by sliding it along the arrow F. The protective cover 15 can also be attached to the shaving or epilation cartridge 14 in any other way, for example, by snap fit.
    [054] The protective cover 15 comprises a housing 152 that extends longitudinally along a longitudinal geometric axis A and is provided with a comb 154 and a trimming blade 156. Due to this comb 154 and the trimming blade 156, the protective cover 15 allows to trim hair to a given length. This is particularly useful when the razor or epilator according to the invention is used to epilate, for example, the groin; obviously the same can be used for other hair removal and, for example, also to cut a beard to a certain length.
    [055] Said length can be adjustable. In that case, or the
    Petition 870190137366, of 12/20/2019, p. 22/97
    12/34 the user can use another protective cover 15 provided with a comb 154 that has indentations of a height H154 different from the height of the first protective cover 15, all of which are larger or all smaller, or the user can use a single protective cover 15 since the comb 154 is detachable from housing 152. In the latter case, the protective cover 15 can receive interchangeable combs 154; a detachable comb 154 has indentations of a different height from the height of another detachable comb 154 all being larger or all smaller. The height provided in any of the combs can also vary from one indentation to the other. The height H154 of the indentations can be comprised between 1 mm and 20 mm, preferably between 2 mm and 10 mm and / or preferably between 10 mm and 15 mm.
    [056] In addition, the number of indentations may differ from one protective cover 15 to the other. For example, the number of indentations can be between 5 and 15, preferably equal to 7. According to the number of indentations provided in a comb in relation to its size, the density of indentations can be more or less important. The greater the density of indentations (for example, 13 indentations for a comb approximately 35 mm in length), the easier it is to manufacture the protective covers 15, especially when manufacturing in series. More precisely, when manufactured in large quantities, the protective covers 15 will be taken to another station where they will be attached to the shaving or epilation cartridge 14. It appears before the trimming blade (s) when the protective covers 15 are to be supplied in a separate mounting station on which the trimming blade (s) will be mounted. In fact, whenever there is a need to manipulate protective covers 15, there is a risk of embarrassing the combs of one comb with the indentations of another. Thus, the density of indentations should be chosen in order to avoid the need
    Petition 870190137366, of 12/20/2019, p. 23/97
    13/34 from another manufacturing stage to untangle and align the combs. In addition, entangled indentations between two or more combs can increase the scrap rate, as entangled parts will lead to broken indentations.
    [057] In addition, the comb 154 can be fixed in a non-detachable manner (which means without movement) on the protective cover 15 or it can be mounted movably on the protective cover 15 in order to adjust the H154 height of the indentations for the desired height.
    [058] As shown in Figures 1A to 1C and 2C to 2F, the trimming blade 156 is elongated along the longitudinal geometric axis A and has an elongated cutting edge 156A parallel to the longitudinal geometric axis A. The trimming blade 156 can be parallel to the longitudinal geometric axis A or it can be tilted / angled with respect to the longitudinal geometric axis A as shown in Figure 3. More precisely, the trimming blade 156 can be angled at Ω an angle Ω with respect to the longitudinal geometric axis A. This angle Ω is preferably between 0 o (the cutting edge edge 156A is parallel to the longitudinal geometric axis A) and 60 o , preferably between 0 o and 45 o or preferably between 0 o and 20 o .
    [059] The comb 154 has many indentations 154A that project obliquely to the longitudinal geometric axis A and protrude forward in relation to the trimming blade 156. More precisely, the angle θ between the indentations 154A and the longitudinal geometric axis A can be 90 o , as shown in Figures 1A to 1C and 2C to 2F; where the indentations 154A are perpendicular to said longitudinal geometric axis A and the indentations protrude forward in relation to said housing 152. The angle θ between indentations 154A and longitudinal geometric axis A can be different from 90 o being between 20 o and 160 o . Furthermore, considering a comb, the angle θ can be the same for each of the indentations or it can be
    Petition 870190137366, of 12/20/2019, p. 24/97
    14/34 vary from one indentation to the other. According to the angle value θ and angle value Ω, indentations 154A can be perpendicular to the trimming blade (s) 156 or not. More precisely, the indentations 154A and the cutting edge (s) of trimming (s) 156A can be perpendicular to said longitudinal geometric axis A and parallel to said longitudinal geometric axis A or indentations 154A and the blade edge (respectively). trimming s (s) 156A can be angled with respect to said longitudinal geometric axis A.
    [060] The angle θ can, for example, be about 70 o as pictured schematically in Figure 1F or 110 o as pictured schematically in Figure 1G. All indentations are skewed, or tilted, in the same direction (right or left) in Figures 1F and 1G.
    [061] The comb 154 as shown schematically in Figure 1H comprises, for example, a first half of the indentations that project obliquely to the right of the comb 154 and the second half of the indentations that project obliquely to the left of the comb 154 The angle θ can, for example, be about 70 o for the first half of the indentations and 110 o for the second half of the indentations.
    [062] The comb 154 as shown schematically in Figure 1I is similar to the one depicted in Figure 1H, but the angle θ varies from one indentation to the other. The first half of the indentations that project obliquely in the right direction of the comb 154 can have an angle θ that decreases from the indentation 154L farther from the center to the indentation 154 'located in the center, while the second half of the indentations that project obliquely in the left direction of the comb 154 it can have an angle θ that increases from the indentation 154R further away from the center to the indentation 154 'located in the center. The angle θ can vary, for example, from about 90 o to 45 o for the first half of the indentations, while the same can
    Petition 870190137366, of 12/20/2019, p. 25/97
    15/34 vary from about 90 o to 135 o for the second half of the indentations.
    [063] The comb 154 as shown schematically in Figure 1J is equipped with indentations that project in such a way that they form a zigzag path. More precisely, indentations can be projected in an oblique and alternative way towards the right and towards the left from an indentation to the adjacent indentation. The angle θ can be the same or it can increase or decrease from the indentation to the next indentation inclined in the same direction (right or left).
    [064] Furthermore, whatever the realization, the 154A indentations can also be equipped with an additional coating or overmoulding on their walls. As shown schematically in Figure 1K, the internal walls 154W of indentations 154A are provided with an additional material 154WR similar to rubber, for example, in order to increase friction in the contact with the hair and help to align the hair that is cut even more. This also leads to better hair adhesion during cutting.
    [065] As pictured schematically in Figure 1L, instead of 154WR rubber walls, rubber or plastic bristles similar to the 154WC toothbrush can also be provided on the 154W internal walls of the 154A indentations to assist in aligning the hair to be cut.
    [066] The length C of indentations 154A measured from the longitudinal front edge 152B of housing 152 can be the same for all indentations as shown in Figures 2A to 2F or can vary, for example, being longer from sides 152A to the center 152C of housing 152 as shown in Figures 1A to 1E in which the indentations follow a curved path as best seen in Figure 1C. In fact, for height H154, length Γ of indentations 154A can vary from one comb
    Petition 870190137366, of 12/20/2019, p. 26/97
    16/34 for another comb, and / or it can also vary, from one indentation to the other, in the same comb. The length C of indentations 154A can be comprised between 5 mm and 40 mm, preferably between 10 mm and 30 mm and / or preferably between 5 mm and 25 mm.
    [067] In addition, the protective cover 15 can be provided with a single comb 154 or many combs 154. As shown in Figures 4A and 4B, the protective cover 15 can comprise two combs 154. Each of these combs 154 can be provided of the features defined here for a comb. More precisely, for example, the indentations of the combs 154 can be transversal to the longitudinal geometric axis A being perpendicular or skewed. The inside wall of the 154A indentations may be provided with an additional coating or rubber or plastic bristles similar to those of a toothbrush. The number, length and height of the indentations can vary between the combs and from one comb to the others. In addition, only one comb 154 may be provided with one or more trimming blades or each of the combs 154 may be provided with one or more trimming blades. As shown in Figures 3A and 3B, only one of the combs 154 is provided with a trimming blade 156.
    [068] The housing 152 comprises a front face 152F and a rear face 152R, with the trimming blade 156 and the comb 154 provided on the front face 152F, while the rear face 152R has a rear opening 158 (see Figures 1D to 1E, 2C to 2D, 2F, and 6B to 6C) through which the connecting members 28 of the shaving or epilation cartridge 14 covered by the protective cover 15 are accessible for connection with the razor handle or shave 12. In fact, the shaver or shaver handle 12 extends through said opening 158 when the protective cover 15 is slid into the shaving or shaving cartridge 14 and when the shaver or shaver handle 12 is attached
    Petition 870190137366, of 12/20/2019, p. 27/97
    17/34 to the shaving or waxing cartridge 14.
    [069] When supplied in the shaving or epilation cartridge 14, the comb 154 and the trimming blade 156 are thus located on the front face 10A of the razor or epilator 10, opposite the connection with the handle 12 as best illustrated in Figures 1C, 6B and 6C.
    [070] The comb 154 comprises indentations 154A and a posterior part 154B from which indentations 154A protrude forward. The comb 154 can be molded in two separate parts corresponding preferably to the indentations 154A and the rear part 154B or it can be molded in a single piece. The comb 154 can be molded directly on the front face 152F of the housing 152 as a type of overmoulding or can be molded with the front face 152F according to the manufacturing process (double injection molding, etc.). In both cases, the indentations protrude forward in relation to the housing 152 and extend beyond the housing 152 and the trimming blade 156.
    [071] The comb 154 is preferably made of a plastic material; the plastic material may be the same as that used for housing 152, more specifically for the rest of housing 152, or it may be different, for example, being softer. In addition, the plastic used for comb 154 may have a different color than that used for housing 152, more specifically for the rest of housing 152.
    [072] The housing 152 is preferably composed of an upper part 153A and a lower part 153B, said comb 154 being provided in said upper part 153A and said trimming blade 156 is located between the upper part 153A and the upper part lower 153B. The housing 152 of the protective cover 15 can be manufactured in one piece or, in order to facilitate the manufacture of the protective cover 15, it can be comprised of many parts assembled together by means of assembly known as
    Petition 870190137366, of 12/20/2019, p. 28/97
    18/34 crimping, welding, etc.
    [073] As mentioned above, the comb 154 and the rest of the housing 152 can be of the same material or can be of different materials, the same also applies to the upper part 153A and the lower part 153B when they are two parts separate.
    [074] According to a first embodiment, the upper part 153A and a lower part 153B of the housing 152 can be a single piece as shown in Figure 1D in which the front face 152F of the housing 152 is preferably composed of an upper part 153A and a lower part 153B, said comb 154 being provided in said upper part 153A and said trimming blade 156 is located between the upper part 153A and the lower part 153B.
    [075] According to a second embodiment, the housing 152 can be made of at least two separate pieces as shown in Figures 2A and 2B. More precisely for that second embodiment, the upper part 153A and a lower part 153B of the housing 152 form, respectively, a comb part and a cover part. In that case, the comb 154 is provided at the top 153A. The trimming blade 156 is located between the top 153A and the bottom 153B, more specifically between the bottom face 153AB of the top 153A (opposite the front face 153AA corresponding to the front face 152F of housing 152) and the top face 153BA of the bottom part 153B (opposite the bottom face 153BB corresponding to the rear face 152R of housing 152).
    [076] In addition, when housing 152 is made of many separate parts as pictured in Figures 2A and 2B, a cavity 153 is provided between the upper part 153A and the lower part 153B, in order to ensure that there is no water contained between these two parts compatible. In fact, this cavity 153 prevents the growth of bacteria or mold that can occur due to
    Petition 870190137366, of 12/20/2019, p. 29/97
    19/34 the humidity that can appear in the small gap created by the two compatible parts and poor air circulation. This cavity 153 is large enough to provide airflow for rapid drying and also makes it more difficult to form droplets of water stagnation.
    [077] Furthermore, as shown in Figure 2C, the trimming blade 156 can be placed directly between the upper part 153A and the lower part 153B of housing 152 or as illustrated, for example, in Figures 1D, with a spacer 153C it can be placed directly between the trimming blade 156 and the bottom part 153B of the front face 152F of the housing 152.
    [078] In addition, the trimming blade 156 can be fixedly mounted (meaning no movement) and not releasable in housing 152, for example, when being riveted in said housing 152 or can be mounted mobile on it, for example, with elastic fingers (not shown) that allow the trimming blade 156 to move when shaving or waxing forces are applied to it.
    [079] The protective cover 15 can also be provided with a forward contact surface with the skin 164 located in front of the trimming blade 156 and a posterior skin contact surface 166 located after the trimming blade 156.
    [080] In addition, the posterior skin contact surface 166 is preferably a highly polished (shiny) surface in order to have a low coefficient of friction that promotes shaving or dry shaving. A very low friction surface on the comb 166 can also be provided, for example, with a highly polished surface in the mold cavity (a type of finish of 32 pm, 16 pm or even 8 pm) used to manufacture the comb 166.
    [081] In addition, the trimming blade 156 can be parallel
    Petition 870190137366, of 12/20/2019, p. 30/97
    20/34 to a plane P tangential to the posterior skin contact surface 166 or can be tilted at an angle to that plane P. In this case, the angle is preferably comprised between 0 and 30 o , with the trim 156 and more precisely its edge 156A is tilted forward towards the P plane.
    [082] In addition, many trimming blades can be provided in housing 152 as shown in Figures 1E and 2D. In that case, the trim blades 156 are stacked on top of each other and can be separated with spacers 153C as detailed hereinafter. This combination of blade (s) and spacer (s) provides the ability to have one or more blades to act as a trimmer.
    [083] In addition, trimming blades 156 can also be parallel to the P plane or can be tilted at an angle to that P plane.
    [084] The protective cover 15 is preferably not provided with any type of connection member that allows the connection to the shaver or shaver handle. It is preferably not in contact with any part of the razor or shaving handle 12. In fact, as detailed hereinafter, the shaving or shaving cartridge 14 can be connected in an articulated way to the shaving handle. shaving or shaving 12, in which case, when the protective cover 15 is placed on the shaving or shaving cartridge 14, it is also pivotally connected to the shaver or shaving handle 12 via the shaving or shaving cartridge 14 and more precisely by means of the connection members 28 of the shaving or epilation cartridge 14.
    [085] The location of the trimming blade (s) 156 and more specifically of its cutting edge (s) 156A is chosen in order to
    Petition 870190137366, of 12/20/2019, p. 31/97
    21/34 offer the best provision for manageability and stability of the protective cover 15 used as a trimmer.
    [086] More specifically and as depicted, for example, in Figure 2A, the PA rotation axis of the shaving or epilation cartridge 14 is located roughly in the middle of the protective cover 15. In fact, the PA rotation axis of the cartridge shaving or waxing 14 is located at a DPA distance from the rear longitudinal face of the protective cover 15, more specifically from the rear most longitudinal face 152RL of housing 152 (opposite the longitudinal front edge 152B of housing 152). In comparison with the distance D156A for the trimming blade edge 156A from the most posterior longitudinal face 152RL, the DPA distance is more or less than half the value. For example, DPA is about 9 mm to 11 mm, preferably about 10 mm, while D156A is about 17 mm to 22 mm, preferably about 18 mm.
    [087] This arrangement offers a limited motion range of the trimming blade (s) 156 which improves the perception of safety and allows more precise control of the trimming blade (s) 156 especially in difficult to reach areas. catch up. This is due to the fact that the shaving or epilation force applied by the user is evenly distributed over the entire trimmer surface due to the symmetrical articulated center (roughly in the middle of the trimmer system). Also, the distance closer to the geometric axis of rotation for the trimming blade edge 156A and the flat surface formed by the posterior skin contact surface 166 which is parallel and above the blade provides an advantage in that the flat surface of contact with the skin pushes on the axis location and always maintains contact with the skin. Thus, such a location prevents a rotation of the shaving or epilation cartridge 14 and thus lifting the trimmer blade (s) 156 away from the skin.
    Petition 870190137366, of 12/20/2019, p. 32/97
    22/34 [088] The rear opening 158 can lead to a side opening 160 provided on one of the side faces 152A of the housing 152 and allows the protective cover 15 to be slid on the shaving or epilation cartridge 14 along the arrow F.
    [089] An opposite side opening 162 can also be provided on the other between the side faces 152A of housing 152 in order to make it easier to slide the protective cover 15 especially by allowing the air pressed by the shaving or shaving cartridge 14 inside the protective cover 15 when the cartridge is slid in the last one it can escape.
    [090] When the protective cover 15 is completely placed on the shaving or epilation cartridge 14, it covers at least the edges of the shaving or epilation blades 16 of the shaving or epilation cartridge 14. In fact, as shown in the Figures, the protective cover 15 completely covers the shaving or epilation blades 16 when it is placed in the shaving or epilation cartridge 14. Especially, no opening or access is possible to the shaving or epilation blades 16 through the protective cover 15, when the last one is completely placed in the shaving or shaving cartridge 14. Therefore, the protective cover can absolutely protect the shaving or shaving blades and the user cannot be injured by them.
    [091] As indicated above, the trimming blade 156 is elongated along the longitudinal axis A and the through wash opening 168 is also elongated along the longitudinal axis A. When the protective cover 15 is attached to the cartridge shaving or shaving 14, for example, after having been slid into the shaving or shaving cartridge 14, the trimming blade 156 can be parallel to one or more
    Petition 870190137366, of 12/20/2019, p. 33/97
    23/34 shaving or shaving razors 16. In fact, when parallel to the shaving or shaving razor (s) 16, the razor or shaving razors 16 are also elongated along the longitudinal geometric axis A. razor blades 16 are preferably perpendicular to the longitudinal direction / L axis of the handle body 18; therefore, the longitudinal geometric axis A is perpendicular to the longitudinal direction L when the protective cover 15 is placed on the shaving or shaving cartridge 14 attached to the shaver or shaving handle 12.
    [092] In addition, the length of the trimming blade 156 may be the same value as that of the shaving or shaving blades 16, but it is preferably shorter in order to have a more accurate shaving or shaving with the trimming blade 156 than with razor blades or hair removal 16.
    [093] In order to be able to wash and evacuate the cut hair, the protective cover 15 is then provided with a washing through opening 168 located in front of the trimming blade 156. To ensure that the shaving or shaving blade 14 do not get dirty when the protective cover 15 is used for shaving or epilation, this washing through opening 168 is displaced by one in relation to the longitudinal front edge 14 'of the shaving or epilation cartridge 14.
    [094] More precisely, when the protective cover 15 is placed on the shaving or shaving cartridge 14, the washing through opening 168 is moved further ahead than the shaving or shaving cartridge housing 14. The displacement value between the washing through opening 168 and the longitudinal front edge 14 'is preferably between 0 mm and 5 mm.
    [095] In addition, the protective cover 15 can be provided with a rear ventilation opening 151 as shown in Figures 2A to 2C
    Petition 870190137366, of 12/20/2019, p. 34/97
    24/34 and 2E. This rear vent 151 is preferably located behind the protective cover 15 opposite the comb indentations 154A in order to allow the lubricating tape 21 of the shaving or epilation cartridge 14 to dry after use for a traditional shave or epilation. In fact, when shaving or shaving traditionally (that is, with the shaving or epilation cartridge 14, the protective cover 15 is removed), the lubricating tape 21 is moist. As shown in Figures 2E and 2F, when the protective cover 15 is placed on the shaving or epilation cartridge 14 after traditional shaving or epilation, the rear vent opening 151 prevents the lubricating tape 21 from sticking to the protective cover 15 that could occur due to swelling of the lubricating tape 21 when wet. The rear vent opening 151 thus prevents the shaving or epilation cartridge 14 and more precisely its lubricating tape 21 from being damaged.
    [096] A method for making such a protective cover 15 will now be described. The method comprises the steps of:
    - providing an upper part 153A having a lower surface 153AB and including retaining pins 155 protruding from said lower surface 153AB,
    - providing a trimming blade 156 that has trimming blade openings 156 'in alignment with said retaining pins 155,
    - mounting said trimming blade 156 on top 153A, said retaining pins 155 passing through trimming blade openings 156 ',
    - providing a lower part 153B which has retaining openings 153 'in alignment with said retaining pins 155,
    - mount the lower part 153B on the trimming blade 156, said retaining pins 155 passing through the retaining openings 153 ',
    Petition 870190137366, of 12/20/2019, p. 35/97
    25/34
    - forming a crimping head 155A at one end of each retaining pin 155, thereby irrevocably riveting both the trimming blade 156 and the upper part 153A on the lower part 153B.
    [097] Retaining pins 155 can be formed as a single piece with the top 153A or they can be separate pieces. In the latter case, the method also comprises the steps of:
    - providing a retaining pin member 155 'comprising retaining pins 155 as shown in Figure 2A and 2B,
    - securely fasten the retaining pin member 155 'to the bottom surface 153AB of the upper part 153A.
    [098] The retaining pin member 155 'can, for example, be overmoulded on the upper part 153A, more specifically on its lower surface 153AB. In that case, the retaining pin member 155 'and the upper part 153A can be made of different materials. Combinations of material can give the advantage of hiding or improving the visibility of the trimming blade by changing the color or type of material or improving the appearance of the trimming blades by allowing the use of in-mold printing or labeling (IML) ) of the retaining pin member 155 'before it is overmolded with the upper part 153A. In this way, graphic applications can be provided to communicate logos, images or other customer information. This can be achieved through thermal printing, IML or other existing applications.
    [099] The material used may comprise a harder plastic material than that used in comb 154 which is preferably soft.
    [0100] When the protective cover 15 comprises many trimming blades, the method also comprises the steps of:
    - provide a spacer 153C that has holes 153'C in alignment with said retaining pins 155,
    Petition 870190137366, of 12/20/2019, p. 36/97
    26/34
    - mounting said spacer 153C on said trimming blade 156, said retaining pins 155 passing through said holes 153'C,
    - providing a second trimming blade 156 that has trimming blade openings 156 'in alignment with said retaining pins 155,
    - mounting said second trimming blade 156 on said spacer 153C, said retaining pins 155 passing through said trimming blade openings 156 ', and
    - form a crimping head at one end of each retaining pin 155, riveting the trimming blades 156, the spacer 153C and the upper part 153A on the lower part 153B through them.
    [0101] The aforementioned steps are particularly adapted for a protective cover 15 comprising two trimming blades; however, a person must understand that in order to manufacture a protective cover 15 that comprises more than two trimming blades, these steps of providing a spacer and a second trimming blade must be repeated before mounting the bottom part 153B on the blade trimmer 156 as many times as necessary, said retaining pins 155 passing through the retaining openings 153 ', and then a crimping head 155A is formed at one end of each retaining pin 155, immovably riveting from it Thus, both the trimming blades 156, the spacers 153C and the upper part 153A on the lower part 153B.
    [0102] In addition, the razor or shaver may be a disposable one or it may be a razor or epilator system in which the shaving or epilation cartridge is discarded when the edge of the blade (s) is blunted . In the latter case, the shaving cartridge or
    Petition 870190137366, of 12/20/2019, p. 37/97
    27/34 epilation 14 is a disposable one and a locking and release mechanism 20 is also provided as shown in greater detail in Figures 7A and 7B and 8A to 8C and allows you to selectively connect the shaving or epilation cartridge 14 to the handle of shaving or shaving 12 or releasing said shaving or shaving cartridge 14 in order to exchange shaving or shaving cartridges.
    [0103] The locking / releasing mechanism 20 is included in the handle body 18, which can therefore be two parts 18 'and 18' '(see Figure 7A). The locking / releasing mechanism 20 includes two arms 22 which can be made, for example, of molded plastic material. The two arms 22 can each extend from a first end 22A located within the handle body 18 towards a free end 22B that can protrude outwardly at the front end 18A of the razor handle or depilate 12. The two arms 22 can be arranged in a V-shape, which diverges from a medial geometric axis X from its first ends 22A towards their respective free ends 22B. The medial geometric axis X is substantially parallel to the longitudinal curved geometric axis L of the handle. The first ends 22A of the two arms 22 can be connected together by a joint 23 formed, for example, as a thin bridge of plastic material that connects the two arms 22 to each other when said arms are molded as a single piece. Joint 23 may have negligible resilient action, or no resilient action, on both arms 22.
    [0104] The two arms 22 also include, respectively, two buttons 24 that can be integrally formed with them and that can protrude laterally out of the handle body 18, for example, through two holes 25 formed in said body of handle 18. The buttons 24 can therefore be surrounded by the handle body 18 in all directions
    Petition 870190137366, of 12/20/2019, p. 38/97
    28/34 around holes 25.
    [0105] The free ends 22B of the arms 22 can be provided, respectively, with two bearings, in particular two cupped bearings 26 which are exposed in the outside direction. The free ends 22B can also be provided with radial bearing means or any known connection means.
    [0106] Each shell bearing 26 may, for example, include a cylindrical concave front face 26A and a side edge 26B protruding outwards and which is also cylindrical in shape. The two front faces 26A and the two side edges 26B have the same cylindrical geometric axis, which corresponds to the geometric axis of rotation of the shaving or epilation cartridge 14 which also corresponds to the longitudinal geometric axis A of the protective cover 15.
    [0107] With reference to Figures 8A, 8B and 8C, the arms 22 are biased elastically opposite each other in the direction of a head locking position (see Figure 8B or 8C) and movable in the direction between them in a position of head release (see Figure 8A).
    [0108] As shown in Figure 8A, the rear face 14B of the shaving or epilation cartridge 14 may include two connecting members or connectors that protrude back, that is, two arched slits with the face facing 28 dimensioned in correspondence with the side edges 26B of the cupped bearings 26 and adapted to receive said side edges 26B to pivotally mount the shaving or shaving cartridge 14 on the handle 12. These arched slits 28 can be formed, respectively, in two ribs that protrude 30 that include two respective side surfaces 29 (and their corresponding inner face 29 ') and two respective inclined surfaces 31 facing each other and extending obliquely towards each other from the top of the ribs
    Petition 870190137366, of 12/20/2019, p. 39/97
    29/34 in the direction of the arcuate slits 28, in order to facilitate the insertion of the cupped bearings 26 in the arcuate slits 28 and can be limited in the direction of the handle 12 by a first concave arcuate surface 32 facing in the direction of the shaving or shaving cartridge 14, and away from the handle 12, by a second larger arched convex surface 34 facing in the direction of the handle 12.
    [0109] The front faces 26A of the cupped bearings 26 are supported, respectively, on the second arched convex surfaces 34. Said second arched convex surfaces 34 can include, respectively, two chamfers 36 to receive the corresponding protrusions 38 of the cupped bearings 26 , in order to limit the angular range of rotation of the shaving or epilation cartridge 14. The rear face 14A of the shaving or epilation cartridge 14 may also include a central rib 40 that has an edge that forms a flat cam surface of top 42 facing away from the shaving or epilation cartridge 14 towards the handle 12.
    [0110] In the case of a disposable shaving or waxing cartridge and with reference to Figures 7A and 7B and 8A to 8C, the locking / releasing mechanism 20 also includes a plunger 48 that is movably mounted substantially along of the medial geometric axis X between the two arms 22. This plunger 48 has a central body 50 and two side flaps 52 that extend opposite each other in the direction of the two arms 22. The central body 50 extends longitudinally parallel to the medial geometric axis X , between a substantially flat first free end 50A that bears against the cam surface 42 of the shaving or shaving cartridge 14 (see Figure 8A), and a second end 50B facing away from the shaving or shaving cartridge 14.
    [0111] A recess 54 becomes hollow in the central body 50, said recess 54 forming a blind hole that opens on the second
    Petition 870190137366, of 12/20/2019, p. 40/97
    30/34 end 50B of the central body 50, in the direction of the handle 12. Each side flap 52 may include an obstacle 56 that protrudes parallel to the medial geometric axis X towards the shaving or epilation cartridge 14, said obstacle 56 being facing an inwardly extending protrusion 58 that belongs to the corresponding arm 22. The protrusion 58 has an opening 60 that is limited inwardly by a rim 62 that belongs to said protrusion 58. In addition, the side flaps 52 of the plunger 48 they can each have, respectively, two ribs 64 that extend in a medial plane of the arms 22, opposite the central body 50.
    [0112] The plunger 48 is biased elastically towards the cam surface 42 of the shaving or shaving cartridge 14 in order to cooperate with it by cam action to skew said shaving or shaving cartridge 14 while rotating on the shaft. rotation A towards a resting position. In the example shown in the Figures, the plunger 48 is elastically skewed by a helical spring 66, which has a first spring end fitted into recess 54 and a second spring end fitted into a recess 68, for example, in the form of a blind hole. , hollow in a 70 arm impeller.
    [0113] The arm impeller 70 is disposed between the arms 22 aligned with the plunger 48 along the medial geometric axis X. More specifically, said arm impeller 70 is disposed between the plunger 48 and the joint 23 along the axis. medial geometric X. The recess 68 opens parallel to the medial geometric axis X in the direction of the plunger 48.
    [0114] The arm impeller 70 is mounted slidably between the arms 22, substantially parallel to the medial geometric axis X and is elasticly biased by said spring 66 in the direction of handle 12, that is, away from the shaving or epilation cartridge 14. Said arm impeller 70 cooperates by means of cam action with the two arms 22, plus
    Petition 870190137366, of 12/20/2019, p. 41/97
    31/34 specifically with the two buttons 24 to skew said arms 22 out and away between them, in the direction of a head locking position shown in Figure 8B, in which side edges 26B of the cupped bearings 26 penetrate the corresponding arc slits 28 of the shaving or epilation cartridge 14.
    [0115] The arm pusher 70 preferably has a central body 72 in which the recess 68 becomes hollow, and two lateral extensions 74 which extend opposite each other in the direction of the two arms 22 and which cooperate by means of cam action respectively with said two arms 22 to skew the arms in the direction of the head locking position. More particularly, these lateral extensions 74 can penetrate two slots 76 formed respectively in the two arms and facing each other. The two side extensions 74 of the arm pusher 70 may have side edges 78 which cooperate by cam action with the respective slots bottom 80. Said lateral edges 78 can diverge from the medial geometric axis X in a direction away from the handle 12, while the bottoms 80 can also diverge from the medial geometric axis in the direction away from the handle 12.
    [0116] Due to these provisions, the same spring 66 is used to bias the plunger 48 elastically towards the cam surface 42 of the shaving or epilation cartridge 14 and to bias the arm impeller 70 away from the shaving or epilation cartridge 14, thus skewing both the shaving or shaving cartridge 14 in the direction of the resting position and the arms 22 towards the shaving or shaving cartridge locking position. It should be noted that the plunger 48 is held between the two arms 22 both by cooperation with the spring 66 by means of seating against the cam surface 42 of the shaving or epilation cartridge 14 and possibly by seating against the
    Petition 870190137366, of 12/20/2019, p. 42/97
    32/34 protrusions 58 of arms 22.
    [0117] When a shaving or shaving cartridge 14 is mounted on the shaver or shaving handle 12, the locking / releasing mechanism 20 is normally in the head locking position (see Figure 8B). Starting with this position, when a user wants to change shaving or epilation cartridges, he first presses both buttons 24, which moves arms 22 towards each other against the cam action of arm impeller 70. During this movement, the arm pusher 70 slides along the medial geometric axis X towards the plunger 48. When the arms 22 have moved sufficiently towards each other to reach the head release position shown in Figure 8A, the shaving cartridge or epilation 14 is released by the cupped bearings 26 and is simultaneously ejected by the plunger 48.
    [0118] The plunger 48 then moves forward to a position that protrudes outward, so that the obstacles 56 of said plunger penetrate the openings 60 of the protrusions 58 of the arms. In this position, as shown in Figure 8A, the arms 22 are held in the head release position by placing the rims 62 against said obstacles 56, and thus cooperate by hook action.
    [0119] Then, when a new shaving or shaving cartridge 14 is attached to the handle 12, the cupped bearings 26 are inserted between the arched slots 28 of the new shaving or shaving cartridge 14 and the cam surface 42 of said new cartridge shaving or shaving pushes the plunger 48 back towards the handle. The arms 22 are then released and moved away from each other under the action of the arm impeller 70, so that the cupped bearings 26 are inserted into the arched slots 28 of the new shaving or epilation cartridge, and the lock / release 20 is again in the position shown in Figure 8B
    Petition 870190137366, of 12/20/2019, p. 43/97
    33/34 (locked head position).
    [0120] When a user presses both buttons 24, the handle is in the head release position as shown in Figure 8A and can receive the ribs 30 of a shaving or epilation cartridge 14 to be locked.
