DETAILED DESCRIPTION OF THE EMBODIMENTS OF THE PRESENT INVENTION
(13) In the various figures, the same references denote identical or similar elements.
(14)
(15) The razor handle 2 has a generally curved shape when viewed laterally as in
(16) Referring to
(17) For instance, the length L of the razor handle 2 is of about 126 mm. The length L5 of the connecting means 5 is of about 17 mm. The length L4 of the elongated body 4 is of about 108 mm.
(18) The razor handle 2 may also define a variable height H and a width W along the length L thereof. The height H of the razor handle 2 may vary along the direction C but is preferably comprised between 15 mm and 25 mm, preferably about 20 mm. As depicted in
(19) It can be seen on the upper and lower views of the razor handle 2 of
(20) The length LEp1 of the first enlarged part Ep1 measured along the longitudinal direction C can be comprised between 10% and 20% of the length L of the razor handle 2. The length Ep2 of the second enlarged part Ep2 measured along the longitudinal direction C can be comprised between 40% and 70% of the length L of the razor handle 2. The length LSp of the slim part Sp can be comprised between 10% and 20% of the length L of the razor handle 2. For instance, the length LEp1 of the first enlarged part Ep1 is of about 25 mm. The length LEp2 of the second enlarged part Ep2 is of about 55 mm. The length LSp of the slim part Sp is of about 25 mm.
(21) As depicted in
(22) This general trapezoidal shape is highlighted on the figures by a virtual trapeze TZ put for instance on
(23) The connecting means 5 are integral with the elongated body 4 and includes two flexible arms 6 extending from the elongated body 4 and protruding toward a free end 6B at the front end 2A of the razor handle 2. In other words, the flexible arms 6 and the elongated body 4 are unitary.
(24) As depicted on
(25) Each arm 6 further has on its upper face a plurality of small cavities 21. Such a structure provides enough structural strength to the connecting means 5 for the purposes of human shaving, while saving weight and costs on this part of the razor handle 2. More precisely, the arms 6 and the flexible tongue 8 have a squared shape with smooth corners, allowing an improved robustness of the connecting means 5.
(26) The elongated body 4 has an outer surface 4E, and more precisely an upper face 4A and a lower face 4B as depicted on
(27) As seen for instance on
(28) The elongated body 4 may thus comprise only one material. In another embodiment, the elongated body 4 may also comprise a second material 23 different from the first material 22. The second material may be chosen among the rubbers. The second material 23 may be an elastomeric material, such as thermoplastic elastomers (TPE). For instance, the second material 23 may be elastic and deformable by a user.
(29) The second material 23 may also be chosen among the plastics. More precisely, the second material 23 may be rigid plastics. Using plastics for the second material 23 permits to have lower cost of production and a simpler manufacturing process of the razor handle 2. Besides, the second material 23 may have a color that is different from the color of the first material 22, thus showing a contrast between the first material 22 and the second material 23. According to another embodiment, the second material 23 may be transparent to give a glaze look to the razor handle 2.
(30) The second material 23 provides the softness required for comfortable hand grasping and firm finger gripping in any shaving position. As depicted in
(31) The elongated body 4 further includes a first hole 9. The first hole 9 is preferably located in the second enlarged part Ep2 of the razor handle 2. The elongated body 4 may further include a second hole 10. The second hole 10 is preferably located in the first enlarged part Ep1 of the razor handle 2.
(32) The first and second holes 9, 10 are preferably through-holes that extend between the upper face 4A and the lower face 4B of the elongate body 4. Alternatively, the first and second holes 9, 10 may also be through-holes that extend between the lateral sides 4C, 4D. Besides, the first and second holes 9, 10 may be blind holes that open on the outer surface 4E of the elongated body 4, and in particular on the upper face 4A or on the lower face 4B.
(33) As shown in
(34) The first hole 9 has a length L9 that may be comprised between 10% and 40% of the length L of the razor handle 2 in the longitudinal direction C. For instance, the length L9 of the first hole 9 along the longitudinal direction is comprised between 40 mm and 60 mm, preferably about 47 mm. The second hole 10 has a length L10 that may be comprised between 10% and 30% of the length L of the razor handle 2 in the longitudinal direction C. For instance, the length L10 of the second hole 10 along the longitudinal direction is comprised between 10 mm and 30 mm, preferably about 22 mm. Also, as illustrated in
(35) The razor handle 2 further includes an element 12 located respectively within the first hole 9. The element 12 is preferably molded within the interior space 9B of the first hole 9. In particular, the element 12 may have a shape that is different from the shape of the first hole 9. Advantageously, the element 12 has a size which is inferior to the size of the first hole 9. According to this particular embodiment, the element 12 does not fill all the interior space 9B of the first hole 9, and some space of the first hole 9 remains free from the element 12. Also, as illustrated on
(36) As depicted on
(37) The element 12 may be integral with the elongated body 4. By integral with, it has to be understood that the element 12 is made of a material of the elongated body 4.
(38) According to an embodiment, the element 12 may be made of the first material 22. For instance, the element 12 may be molded together with the elongated body 4 from the first material 22, thereby allowing reducing manufacturing cost.
(39) The element 12 may also be made of the second material 23. As depicted on
(40) As illustrated in
(41) The element 12 may be located in the vicinity of the rear end 2B. Preferably, the element 12 is centered on a second point 12A which is located at a distance L12 comprised between 10% and 30% of the length L of the razor handle 2 measured along the longitudinal direction C from the rear end 2B. For instance, the distance L12 may be of about 21 mm from the rear end 2B.
(42) The razor handle 2 may also comprise an insert 11 located within the interior space 10B of the second hole 10. The insert 11 may be partially encapsulated within the second hole 10 as illustrated in
(43) The insert 11 may have a spherical shape. The insert 11 may have an ovoid shape. More generally, the insert 11 may have any other shape such as a parallelipipedic, cubical or cylindrical shape. In particular, the insert 11 may have a shape that is different from the shape of the second hole 10. Advantageously, the insert 11 has a size which is inferior to the size of the second hole 10. Also, as illustrated on
(44) The insert 11 is preferably made in a material chosen among the metals, the plastics and the rubbers. In particular, the insert 11 is preferably made in a rigid material having a density that is significantly different from the density of the first material 22 and of the second material 23 of the elongated body 4. The insert 11 thus contribute to raise weight of the razor handle 2 without significantly increasing the volume of the razor handle 2. As a consequence, the razor handle 2 can be heavy enough to provide a good shaving and to make sure that a good contact is provided between the blades 3A of the shaving cartridge 3 and the skin of the user to be shaved. In the embodiment in which the shaving cartridge 3 includes a trimming blade, the razor handle 2 may be reversed of 90 degrees to use this trimming blade. In trimming position, the insert 11 retains the same purpose as during shaving. The insert 11 still provides a defined surface that helps control the contact between the trimming blade and the hair to be trimmed. Besides, the insert 11 can still be used as a grip surface by the user by positioning his fingers preferably on the surface of the insert 11 which is not encapsulated on the lower face 4B of the elongated body 4. The user is therefore not forced to adjust finger placement and can use the razor handle 2 in the same manner as for shaving.
(45) Besides, due to the insert 11, the elongated body 4 can therefore be in a material which is lighter and cheaper when compared to the material used in known razor handles. Nevertheless, despite the lightness of the first and second materials 22, 23, the razor handle 2 still has a good quality appearance and an optimized weight thanks to the insert 11. Since the material of the insert 11 can be different from the first and second material 22, 23 of the elongated body 4, the user can easily determine through touch whether his fingers are well placed on the insert 11 of the razor handle 2. By determining the location of the insert 11, the user can also be guided to place his fingers on the free space of the second hole 10 that may serve as finger rest areas. Preferably, the insert 11 is only made of metal and does not comprise any other material.
(46) The insert 11 can also be made with several materials. In particular, the insert 11 can be covered with a layer of another material having a smooth surface. As an example, the insert 11 may be made of metal and covered by a layer of rubber. In this embodiment, the layer can have a surface finish comprised between 0.5 gm and 1.6 gm (roughness Ra). As another alternative, the insert 11 may be a sphere of which one hemisphere is made of rubber and the other hemisphere is made of plastic. The insert 11 may thus serve a double purpose by providing different types of finger rest areas.
(47) The insert 11 is preferably maintained, advantageously secured, within the second hole 10 and can therefore not be detached from the second hole 10 by a user. Besides, the insert 11 cannot move in any manner in the second hole 10. As a consequence, the insert 11 is not movable (i.e. immovable or motionless) respectively relative to the second hole 10. The non-movable insert 11 thus forms a finger rest area. More precisely, the insert 11 cannot slide in the second hole 10. More particularly, as depicted in
(48) However, in another embodiment, the insert 11 may be a sphere that can rotate on itself about its own axis in all directions. Also, a gap may be provided between the insert 11 and the retaining ring 13 in order to facilitate the rotation of the insert 11 when it is a sphere. The gap may be comprised between 0.005 gm and 0.025 gm depending on the chosen rotational freedom of the insert 11. A smaller gap prevents the insert 11 from rotating easily whereas a bigger gap facilitates the rotation. The surface finish of the insert 11 is adapted to allow this movability, especially the rotation. In the case where the insert 11 includes two hemispheres made of different materials and thus having different density, the user can switch between the two hemispheres as needed by rotating the insert 11. A user that may position one of his fingers on such a movable insert 11 will find difficult to shave as his finger(s) will constantly slip on the insert 11. Shaving will therefore be imprecise and uncomfortable. As a consequence, when the insert 11 is movable relative to the second hole 10, it cannot form a finger rest area.
(49) The insert 11 is located in the vicinity of the front end 2A. Preferably, the insert 11 is centered on a first point 11A which is located at a distance L11 comprised between 10% and 30% of the length L of the razor handle 2 measured along the longitudinal direction C from the front end 2A. For instance, the distance L11 may be of about 25 mm from the front end 2A.
(50) The surface 12B of the element 12 and/or the surface 11B of the insert 11 can be directly or indirectly, as detailed hereafter, touchable with a finger of a user. Also, the outer surface 12B of the element 12 and/or the surface 11B of the insert 11 can form finger rest areas on the upper face 4A and/or on the lower face 4B of the elongated body 4. In this manner, when a user wants to shave, he may position his fingers on the location of the element 12 and/or of the insert 11, and preferably on the surfaces 12B of the element 12 and/or on the outer surface 11B of the insert 11 which are not encapsulated.
(51) Preferably, the element 12 and the insert 11 enhance hand grasping in certain shaving positions, such as in a position where the razor handle 2 is held between the index and the thumb, the thumb resting on the insert 11 on the upper face 4A whereas the index rests on the insert 11 on the lower face 4B of the razor handle 2. In another shaving position, the thumb and the index of the user can also rest on the element 12. However, the element 12 may not be directly touchable with a finger of a user on the upper face 4A as the elongated bar 14 may cover partially the element 12. According to this alternative, the element 12 is covered at least partially with the first material 22 of the elongated bar 14. The user may position his finger(s) on the elongated bar 14 on the upper face 4A of the elongated body 4 when shaving.
(52) The material chosen for the insert 11 and/or for the element 12 may also have an impact on the sensing experience of the user when he positions his fingers on the insert 11 and on the element 12. As an example, an insert 11 made of metal provides a pin-point contact with the fingers of the user, thus allowing the communication of all transmitted vibrations from shaving. To the contrary, an element 12 made of the second material 23 chosen for instance among the rubbers, such as thermoplastics, absorbs most of the vibrations from shaving and does not transmit them to the fingers of the user.
(53) The insert 11 provided within the second hole 10 may be made of metal whereas the element 12 provided within the first hole 9 may be made of rubber. According to this alternative, the insert 11, which is thus in metal, reinforces the comfort feeling and handle control when a user places his/her index finger on it. It also enhances the directional tactile feedback of the user due to the difference of texture, temperature and shape that exist between the insert 11 in metal and the second material 23 of the element 12.
(54) The insert 11 and the element 12 may also have an irregular surface, for instance with craters or bumps due to a knurled pattern or a divot pattern. As a matter of fact, the type of surface of the insert 11 and of the element 12 affect the tactile sensing of the user when he positions his fingers on the insert 11 and/or on the element 12.
(55) The insert 11 and the element 12 may have similar shapes or different ones. The insert 11 and the element 12 may have the same dimensions or may have different ones. As depicted on the
(56) As illustrated on
(57) Known razors without any element or insert usually have a center of balance that is located in the center of the razor handle, or slightly towards the front end toward the razor handle. To this end, the rear part of the razor handle cannot be much larger than its front part, and vice versa, in order to achieve this center of balance. In the present invention, by adding an insert 11 at a precise location from the front end 2A of the razor handle 2, it is possible to control the location of this center of balance regardless the shape of the razor handle 2. For instance, the center of balance may be positioned at the center of the razor handle 2 in the longitudinal direction C even though the second enlarged part Ep2 is significantly larger than the first enlarged part Ep1. Preferably, the inclusion of the insert 11 and of the element 12 does not lead to an excessive deformation of the shape of the elongated body 4. The shape of the elongated 4 preferably remains similar to the shape of an elongated body that would not include any insert or any element.
(58) The lateral sides 4C, 4D of the elongated body 4 further includes a plurality of smooth ribs 16 made of the second material 23. As shown in
(59) As depicted on
(60) According to an embodiment, it is possible to exchange the positions of the element 12 and of the insert 11. More precisely, the element 12 may be located in the vicinity of the front end 2A and the insert 11 may be located in the vicinity of the rear end 2B. According to this embodiment, the first hole 9 is more particularly located in the vicinity of the front end 2A and the second hole 10 is located in the vicinity of the rear end 2B. Also, the insert 11 is thus centered on a first point 11A which is located at a distance L11 comprised between 10% and 30% of the length L of the razor handle 2 measured along the longitudinal direction C from the rear end 2B. For instance, the distance L11 may be of about 21 mm from the rear end 2B. The element 12 is centered on a second point 12A which is located at a distance L12 comprised between 10% and 30% of the length L of the razor handle 2 measured along the longitudinal direction C from the front end 2A. For instance, the distance L12 may be of about 25 mm from the front end 2A.
(61) Besides, the razor handle 2 may not comprise an insert 11 but may instead comprise a second element identical to the element 12 located respectively within the interior space 10B of the second hole 10. According to this embodiment, the second element may be made of the first material 22 or of the second material 23.
(62) The razor handle 2 may have more than one insert and more than one fixed elements. For instance, the razor handle 2 may comprise a third hole in which is located another insert or another element. Besides, several elements and/or inserts may be located within the same hole. For instance, several inserts having small diameters, for instance a trinity of inserts, can be located within the second hole 10. Similarly, several small elements, for instance a trinity of elements, may be located within the first hole 9.
