Definitions

  • J 5 l o a Z5 50a may 29 0 .5 33/ 70A 5/ lnvenlor Attorneys United States Patent SAFETY RAZOR BLADE HOLDER AND ELECTRIC RAZOR Raymond Henry Greenly, Le Clos du Bon Pere, Celigny, Geneva, Switzerland Filed Sept. 28, 1964, Ser. No. 399,707 Claims priority, application Great Britain, Oct. 7, 1963, 39,449/63 6 Claims. (Cl. 30-605)
  • the present invention relates to safety razor blade holders and to electric razors using such holders.
  • Conventional safety razor blade holders comprise a body member to the upper surface of which is adapted to locate a razor, the latter being held in place either by a hinged clamping member operated by turning a rotatable member mounted on the shank or by means of a screw connection between the shank and a clamping plate placed on the upper side of the razor blade.
  • a safety razor blade holder comprising a body portion adapted to locate a safety razor blade and being provided with a shank, a sleeve member slidable axially relative to said shank and having a toggle connection With said body portion whereby, upon relative axial movement between the body portion and the sleeve member, a clamp secured to said toggle connection is moved into and out of a closed position in which it clamps a razor blade in position on said body portion.
  • the holder of the present invention may be of a simple construction and may readily be made from only four parts. At the same time it can easily be opened .and closed simply by relative axial movement between the sleeve member and the shank.
  • the toggle connection comprises four toggle members each pivoted to the body portion and to the sleeve member, in which case the clamp may comprise two clamping bars extending longitudinally over the body portion and secured to the toggle member at each end of the body portion.
  • the upper surface of the body portion includes a permanent magnet, whereby a blade may be held in contact with the body portion even when the clamp is in the open position.
  • a safety razor blade holder comprising a shank, a body portion adapted to locate a safety razor blade, areleasable clamp for securing a blade to said body portion and a magnet located in said body portion whereby a blade may be held against said body portion even when the clamp is in the open position.
  • a safety razor including a holder of the invention the shank being connected to a motor which is adapted to vibrate the shank in a direction normal to the length of the body portion and to the shank axis, whereby a blade held in said holder is vibrated in its own plane transverse to its edge.
  • Existing shaving machines employ rotating, vibrating, or oscillating blades or sets of blades which move over metal shields in the form of suitably designed grilles which themselves are stationary or receive a motion which "ice is different from that of the blade. Since the shields or grilles prevent the blades from being in direct contact with the skin or at least render such contact only partial, such machines cannot give a perfectly smooth shave, since the shaving action can take place only at a distance from the skin. With the razor of the present invention, a very much closer and smoother shave can be obtained than with the conventional shaving machine referred to above as the blade is in direct contact with the skin. As compared with ordinary safety razors and cut throat razors, the razor of this invention provides a closer shave due to the vibration of the blade. The machine can be used either for wet shaving or dry shaving and indeed it can also be used for cutting or trimming hair.
  • the motor advantageously comprises a casing, an armature pivotally mounted with respect to said casing, the shank of said holder being secured to or integral with the armature, an E-shaped coil core secured within the casing with the pole pieces adjacent said armature on the side of-the pivotal connection remote from the shank, elastic foam material between the pole pieces and armature, and an electromagnetic coil wound on said core and adapted to be connected to an A.C. supply.
  • a safety razor comprising a holder adapted to hold a safety razor blade, a casing, an armature pivotally mounted with respect to said casing, the shank of said holder being secured to or integral with the armature, an E-shaped coil core secured within the casing with the pole pieces adjacent to the armature on the side of the pivotal connection remote from the shank, elastic foam material between the pole pieces and armature and an electro-magnetic coil wound on the core and adapted to be connected to an A.C. supply.
  • the pivotable connection between the armature and casing is provided by a leaf spring secured to the armature. The leaf spring may also be secured to the E-shaped coil core.
  • the blade is caused to perform 25 to 200 cycles per second and the amplitude of motion is desirably in the range of 0.1 to 3.0 mm., when the blade is not in contact with the skin.
  • the amplitude may well be reduced when the razor is in use due to the pressure applied.
  • FIGURE 1 is a cross sectional view showing the holder shown in the closed position
  • FIGURE 2 is a view similar to FIGURE 1 of the holder shown in the open position;
  • FIGURE 3 is a top plan view of the 'body portion of the holder of FIGURES 1 and 2;
  • FIGURE 4 is a top plan view to a reduced scale of the sleeve member of the holder illustrated in- FIGURES l and 2;
  • FIGURE 5 is a top plan view of one pair of toggle connections of the holder of FIGURES 1 and 2;
  • FIGURE 6 is a schematic view partly in cross section of a razor according to the invention using the holder of FIGURES 1 to 5.
  • FIGURES 1 through 5 of the drawings there is illustrated therein a holder comprising a shank or handle 10 surrounded by a sleeve member 11 which includes cylindrical sleeve 12. and four longitudinal arms 13 (FIGURE 4). At their outer ends the arms 13 are provided with bearings plates 14 having central bearing apertures 15.
  • the shank 10 is formed integral with a substantially rectangular body portion 16 on which a razor blade may be mounted.
  • the body portion 16 has a central boss 17, from which extend two longitudinal ribs 18 for locating a blade in the cor rect position on the body portion 16, which has at each end a bearing plate 19 of substantially elliptical cross-section each plate 19 being provided with two bearing apertures 20.
  • a toggle connection is provided between the plates 19 and the arms 13 by four toggle plates 21. These plates are connected in pairs by a longitudinal extending bar 22 and by a clamping bar 23. A stud 24 extends outwardly from each plate on the same axis as the bar 22 and seats in bearing stud aperture 20 of end plates 19. A further bearing stud 25 on each plate engages in the bearing aperture 15 of the end plates 14 on arms 13 of sleeve member 11. Obviously, the connection described above renders the sleeve non-rotatable relative to the shank so that it slides axially thereon without any rotation.
  • the sleeve member 11 is raised to the position shown in FIGURE 2 and a razor blade is located on the body portion 16, the slot in the razor blade registering with the boss 17 and rib 18.
  • the sleeve member 11 is then pulled downwardly relative to the shank 11 during which movement the arms 13 of the sleeve member flex inwardly towards the axis of the member and permit the studs 25 to move beyond the over-centre position, i.e. the plane between the axes of studs 24 thereby creating a snap-action connection.
  • the holder is preferably provided with a permanent magnet 28 shown in phantom in FIGURES 1 and 2.
  • this magnet 28 prevents the blade readily dislodging from the upper surface 27 of body portion 16.
  • a user can simply open the holder, to the position shown in FIGURE 2 thus releasing the cutting edges of the blade from the holder itself and place the holder complete with blade in water or preferably under a running tap and thus clean off the shaving soap etc., from the blade edges.
  • FIGURE 6 there is illustrated therein an electric razor incorporating the holder shown in FIGURES 1 to 5.
  • the razor comprises a casing 29 formed in two halves 30 and 31 of a plastics material each half having in its end an aperture.
  • the upper half 30 is formed on one side with a ribbed portion 30a to facilitate handling of the casing and on the opposite side with a thickened wall 32.
  • Secured to the wall 32 by means of bolts 34 is an E shaped coil core 33 having three pole pieces 35, 36 and 37, an electro magnetic coil 50 being wrapped round the core in a conventional manner.
  • An armature 38 positioned adjacent to pole pieces 35, 36 and 37, extends upwardly out through the aperture in the casing half 30 and is riveted to a leaf spring 39 carried by a mounting bracket 40 which is held to the upper pole piece 35 by means of rivets.
  • the upper riveted end of the armature and the leaf spring are moulded into an insulating connector 41 having an integral threaded stud which is screwed into the shank 10 of the safety razor holder, illustrated in FIGURES 1 to 5.
  • the moulded connector 41 is encircled by an elastic grommet 42 which serves to seal the aperture in the casing half 30 and yet permits limited movement of the armature, spring and connector.
  • a cushion 51 of foam plastic material Between each of the pole pieces and the adjacent portion of the armature 38 there is provided a cushion 51 of foam plastic material.
  • the leads 43 to the coil wound on the core 33 pass out through the aperture in the lower casing half 31 and are sealed with respect to the lower casing half by a grommet 44.
  • the junction between the upper and lower casing halves may be made water-tight by any suitable means, and, if desired, the whole interior of the casing may be filled with a foam plastic material to reduce the vibration of the casing.
  • the lead 43 is connected to an AC. supply and the alternating electro-magnetic field created at the pole pieces causes the armature 38 to vibrate against the action of the lead spring 39, which restricts the movement of the armature to simulate oscillation about a pivot, normal to the plane of FIGURE 6 and passing substantially through the aperture in the upper casing half 30.
  • This movement of the armature is transmitted by the connector 41 to the shank 10 of the razor blade holder so that a blade secured therein is used to vibrate in the plane of the blade in a direction normal to the edge of the blade.
  • the armature may simply be pivoted to the casing and a spring of the coil compression type positioned between the pole face 37 and the armature 38.
  • the razor of the present invention may be used either dry or with shaving soap, creams, oils, lotions and emulsions of the kind which would clog and hinder or prevent satisfactory performance of other types of electric razors.
  • These lotions may serve the purpose of combined preand after-shave lotion and the machine can enable all these advantages to be combined with the simple application of a lotion before using the razor.
  • the razor provide a more satisfactory shave than can be achieved either by using the conventional dry shavers or by using safety razors but also benefits are obtained .from the vibratory effect massaging the skin, tuning up the facial muscles and giving a pleasurable effect of vibration while shaving. The pull or drag which is experienced with ordinary safety razors is substantially reduced or eliminated.
  • a safety razor blade holder comprising:
  • a body member having an upper surface shaped to locate a safety razor blade
  • a sleeve member encircling and non-rotatably axially slidably relative to said shank;
  • clamp means secured to said connection means for securing said blade on said upper surface of said body member upon relative axial movement in one direction between said sleeve member and said shank, said clamp means being released upon relative axial movement in the opposite direction between said sleeve member and said shank so that said blade can be removed.
  • Thesafety razor blade holder defined in claim 1 including *a magnet located in said upper surface, said magnet holding said blade in contact with said upper surface when said clamp means is removed from said blade.
  • said connecting means comprises four resilient arms affixed to said sleeve member and extending in a plane transverse to said body member and four toggle members movably pivoted to the free end of said resilient arms and fixedly pivoted to said body member, said clamp means being connected to and extending between pairs of said toggle members.
  • each of said pivotal connections between said free ends of said resilient arms and said toggle members moves in an arcuate path equiradially disposed from the axis defining the fixed pivot of associated pairs of toggle members and wherein said free ends of said resilient arms are flexed inwardly of said fixed pivotal axis and toward said shank so that said arms are passed over center defined by a plane extending between all of said fixed pivotal axes.
  • the safety razor blade holder defined in claim 1 including vibratory motor means for oscillating said holder so that when said blade having a cutting edge is located on said surface of said holder, said blade moves in a direction transverse to its cutting edge and substantially in the plane of said blade,
