Definitions

  • the comb In certain types of conventionaldry shavers the comb itself is somewhat flexible and resilient.
  • the cutter For the shaver to be effective, the cutter must make smooth sliding contact with the interior of the-comb. If the comb is depressed at a portion thereof, the vibrating cutter may snag on theinterior surface of the comb causing the comb to vibrate with the cutter. The sharpness of the cutter can be adversely affected and the quality of the shave obtained therewith degraded. Moreover, an unpleasant sound is generated and the comb itself may be damaged.
  • a flexible comb engages a cutter and the ends of the foil are held against the interior surfaces of side walls ofa compartment of the shaver.
  • the comb is held slidably against the interior walls of the said compartment by means of magnets which may be secured in the side walls, the side walls being of a non-ferromagnetic material such as a plastic, while the comb is made of a ferromagnetic material.
  • the side walls of the compartment may be of a ferromagnetic material and the magnet may be bonded proximate the ends of the comb.
  • the end portions of the comb are made, at least partly, of a ferromagnetic material while the rest of the comb is ofa non-ferromagnetic material and the comb is held slidably against said side walls by magnets therein.
  • that surface of each magnet which is to hold an end portion of the comb should be flush with the inner surface of aside wall.
  • the magnets should be of such strength as to permit sliding of the end portions of the comb across'same under moderate pressure such as is applied during shaving.
  • the magnets should be sufficiently strong to prevent the end portions of the comb from drawing away from same in a direction perpendicular to the surface of the magnets.
  • an object of the present invention is to provide a dry shaver having improved means for holding a comb thereof in engagement with a cutter.
  • Another object of the present invention is a dry shaver having improved means of holding the comb thereof in a holding compartment in the case of the dry shaver.
  • Another object of the present invention is to provide an improved dry shaver wherein interference with the cutter as the result of increased pressure against the skin of the individual shaving is avoided.
  • Still another object of the present invention is an improved dry shaver wherein the comb can move within the holding compartment of said shaver in response to variations in pressure applied by the individual using such shaver.
  • Yet another object of the present invention is an improved dry shaver having a comb which is easily removed for replacement or for cleaning of said shaver and easily replaced in position.
  • the invention accordingly comprises an article of manufacture possessing the features, properties, and the relation of elements which will be exemplified in the article hereinafter described, and the scope of the invention will be indicated in the claims.
  • FIG. 1 is a cross-sectional view of a dry shaver in accordance with the present invention.
  • FIG. 2 is a sectional viewtaken along line 2-2 of FIG. 1;
  • FIG. 3 is a sectional view of a dry shaver including an alternate comb holding means constructed in accordance with the invention
  • FIG. 4 is a sectional view of a dry shaver including another alternative comb holding means constructed 'in accordance with the invention
  • FIG. 5 is a sectional view of a dry shaver including still another alternative comb holding means constructed in accordance with the invention.
  • FIG. 6 is a sectional view of the embodiment shown in FIG. 5, taken along line B-B thereof.
  • a case 1 containing driving means (not shown) has a vibrating cutter 4 supported on a vibrator 2 connected to said driving means through upper opening 3.
  • Cutter 4 is held in close engagement with comb 6 by cutter spring 5 mounted on vibrator 2.
  • the spring constant of spring 5 is such that while it holds cutter 4 firmly against comb 6, comb 6 is held against cutter 4 slidably.
  • End portions 14 of comb 6 fit within the holding compartment formed by side walls 7 and end walls 15 (FIG. 2). End portions 14 of comb 6 are held strongly but slidably and removably against the inner surfaces of magnets 12. Magnets 12 are of the permanent type and are disposed in recesses 11 so that they are preferably flush with inner surfaces 8 of side walls 7.
  • both comb 6 and vibrator 4 can move inward and outward in response to changes in pressure against the skin applied by the individual shaving, comb 6 and cutter 4 maintaining optimum engagement therebetween so that snagging of the cutter on the comb is avoided and so that the quality of the shave provided by the dry shaver is not degraded.
  • FIG. 1 can just as readily represent a shaver in which side walls 7 are ferromagnetic, comb 6 is of a non-ferromagnetic material such as some of the stainless steels, and magnets 12 are bonded to end portions 14 of comb 6.
  • only end portions 14 are ferromagnetic while the remainder of comb 6 is non-ferromagnetic.
  • the portion of comb 6 which is ferromagnetic could be a separate strip of steel or nickel embedded in or attached to end portions 14 of comb 6.
  • each north pole in an end portion 14 should be adjacent a south pole in a magnet 12 and vice versa.
  • This arrangement is particularly desirable in that it assists in maintaining the magnetic strength of magnets 12 at or near their original values. Needless to say, the presence of ferromagnetic material adjacent to magnets 12 helps to maintain the magnetic strength thereof.
  • FIGS. 3-6 Illustrative of the foregoing embodiments, reference is had to FIGS. 3-6. In the following description, substantially identical parts are identically numbered.
  • side walls 7 of shaver case 1 is fabricated of molded plastic.
  • Overlying end portions 14 of comb 6 is a ferromagnetic material which is connected to respective end portions 14.
  • Comb 6 is fabricated of non-magnetic material. The embodiment operates in the manner described above.
  • side walls 7 of case 1 are fabricated of a ferromagnetic material.
  • a permanent magnet 12 is connected to the interior surface of each respective end portion 14 of comb 6. This embodiment also operates in the manner described above.
  • a magnetized comb reinforcing plate 17 is connected to the exterior surface of each respective end portion 14 of comb 6.
  • the polarity of each magnetized comb reinforcing plate 17 is shown in phantom line by the designations *S" and N. Plates 17 enhance the attraction between comb 6 and permanent magnets 12 and also reinforce end portions 14 of comb 6.
  • permanent magnets 12 are located in respective recesses 11 so that respective N and S-poles thereof are proximate respective S and N-poles of plates 17.
  • comb 6 may be fabricated of ferromagnetic material. The manner of operation of this embodiment is also as described above.
  • a comb and a vibrating cutter are held in engagement with appropriate firmness to give a close and comfortable shave independent of the pressure exerted upon the skin of the individual shaving.
  • the means by which said comb is held in the holding compartment of the shaver case permits sliding engagement between the inner surfaces of the side walls of said compartment, this being a type of engagement which substantially eliminates the danger of damage resulting from accidental shock to the comb or to the case.
  • the comb can readily be removed from the case for the purpose of cleaning out beard dust or for replacing the comb.
  • the sharpness of the combination is not decreased in use so that an excellent shave is obtained from such a shaver throughout its life.
  • An improvement in a dry shaver including a vibrating cutter, a comb engaging said cutter slidably and a case having side and end walls defining a compartment into which the end portions of said comb fit, wherein said improvement comprises magnetic means for holding said comb slidably and removably against said side walls.
  • said holding means comprises pins on the interior surfaces of said side walls and walls defining slots in said comb, said pins fitting within said slots for relative motion therebetween.
