Definitions

  • This invention relates to a dry-shaving apparatus, the shear plate of which, in particular a shear cap, can be depressed against spring action until in a stop position, in which the plate, in a position parallel to a supporting surface of the apparatus on the skin, still partially projects above that supporting surface or lies substantially level therewith.
  • the pressure of the shear cap on the kin is at first determined by the pressure of the spring which forces the shear cap outwards. After reaching the stop, the user may, if desired, increase the said pressure in accordance with the force with which he pushes the shaving apparatus against the skin.
  • the shear action is influenced by the difference in height between the shear cap :and the stretching edge, that is to say the above-mentioned supporting surface. If in the stop position the stretching edge is low with respect to the shear cap, the run-in, i.e. the possibility of the hair to enter the cutting area through the slots in the side wall of the shear cap, is large because the skin is stretched on the shear cap. However, with some users this results in irritation.
  • the stretching edge is located substantially ⁇ as high as the shear cap, the run-in is small because the stretching edge holds the skin flat. With some razor users this prevents the possibility of readily shaving out.
  • the object of the invention is to provide a device which can better be adapted to the various conditions and uses, which device is characterized in that the stop member is adjustably provided for various depths of depression of the shear plate.
  • the users are capable of adjusting, according to their individual needs, the distance through which the shear cap can be depressed against increasing spring pressure and determining themselves the position of the height of the cap with respect to the stretching edge in the position of the firmly engaging cap.
  • the function of the present device is to provide a vertically adjustable shear plate in which the shear plate may be selectively adjusted within a certain predetermined range of stops and full pressure may be applied. upon the shear plate in the stop position without additionally loading the shaver motor.
  • a favourable embodiment of the invention is that the stop member is adjustably provided in its height below a supporting edge of the shear plate.
  • FIG. 5 is a perspective view of the embodiment shown in FIG. 4.
  • FIGS. 6a and 6b are perspective views of the inner circumference of the shaving head mounts separated from the housing structure shown in FIG. 5.
  • FIG. 6c is a perspective view of the finger-operated lever 27.
  • FIG. 6d is a perspective view of the shear plate inner frame.
  • FIG. 7 is a bottom plan View of the shaver head frame member of this embodiment in which the parts shown in FIG. 6 are omitted.
  • FIG. 8 is a top plan view of a shear cap which is used in the second embodiment.
  • FIG. 9 shows a cross-section of a third embodiment.
  • FIG. 10 shows a cross-section of a fourth embodiment.
  • the housing 1 comprise a shaving head 2 which can be removed in known manner to expose openings 1A and 1B therein and comprises itself two shear plates 3 closing said openings 1A and 1B.
  • shear plates 3 can be depressed against spring action because they rest in a manner corresponding to that shown in FIG. 9 on the driven blades 42 which are under spring action by means of springs 30. For the sake of clarity these blades are not shown in FIGS. 1 and 2.
  • a stop ring 5 as clearly and individually seen in FIG. 3.
  • This ring is provided with a series of upright teeth 6, the tips of which form the stop surface for the supporting edge 4 of the shear cap 3.
  • the stop ring 5 is a means for adjusting the shear plate of a dry shaver to various heights relative to the housing 1. This is accomplished by rotating a lever 11, hereinafter described.
  • the space between the teeth prevents the accumulation of parts of hair or dirt on the stop edge which might easily occur if a flat stop ring were used.
  • the lower side of said ring is provided with 'a number of slightly inclined parts 7 which cooperatef with corresponding inclined surfiaces 8 on the part of the housing on which the ring 5 rests.
  • the stop surface consequentiy can be adjusted continually between a lowest position and a position which is higher by twice the height of the inclined parts 7.
  • the two stop rings are coupled together because one of them is provided with a fork 9 and the other with a pin 10 located between the limbs of the fork 9.
  • One of the stop rings i connected to a lever 11 which can be operated from outside the housing.
  • FIGS. 4 to 8 The second embodiment is shown in FIGS. 4 to 8.
  • a shaving head 12 is provided in nor-. mal manner at the top side with apertures which are bounded by stretching edges 13 and edges of engagement 14 for the shear plates 15 which are provided with a number of radially projecting supporting abutments 16.
  • rotatable stop cylinder 17 comprising an outwardly thickened lower edge 18 is provided in a manner such that it immediately joins the lower side of the stretching edge 13.
  • a number of step-shaped recesses 19 are provided in the cylinder wall 17. Each step-shaped recess 19 forms a number of steps 20 and each step forms a surface of engagement for the abutments 16 of the shear plate 15.
  • the abutments 16 are located. in the shaving head 12 in grooves 21 which are provided in the inner edge of the stretching edges and extend from the edge of engagement 14 downwards so that, when the cylinder 17 is rotated, the shear cap is not rotated but is-only capable of performing an up and down movement the depth of which is restricted by the surfaces of the various steps 20.
  • Grooves 22 are provided on the inside of the cylinder wall1l7 and the thickened lower edge 18 joining the stepshaped recesses 19, the mutual distance of said grooves corresponding to that of the abutments 16, so that the shear plate can be removed downwards and cleaned.
  • the stop cylinder 17 is journalled in the shaving head 12 by the edge 18 and enclosed by a shear plate 23. This plate is also provided with grooves 24 corresponding to the grooves21 and 22.
  • the stop cylinders are coupled together by a fork 25 on the one cylinder and an abutment 26 on the other, the cylinders being rotated by mesansof a lever 27 projecting outside the shaving head. This is clearly seen in FIGS. 4, 6a, 6b and 60.
  • a shaving head 2 comprising shear plates 3 with supporting edges 4 is provided on the housing 1.
  • the stop surfaces for the supporting edges 4 are constituted by the tips of two series of upright teeth 6.
  • FIG. 9 the position is shown in which the shear plates 3 engage the shaving head as a result of the spring action which is exerted on the driven blades 32.
  • a driven blade 34 is in normal manner provided below the shear plate 33 which blade is coupled to a driving shaft 35 which consists of two parts, the driving shaft 13-5 and the elongated shaft 235, the driving shaft 135 being depressible in known manner through a certain distance against spring action in the form of spring 41 with respect to the elongated shaft 235.
  • This driving shaft 35 together with the toothed wheel 36 are adjustable in height because the elongated shaft 235 rests on a step 37 of a step-shaped wedge 38, which may be moved back and forth by means of an arm 39. As a result of this, the depth of depression of the shear plate 33 is adjustable in its height.
  • the arm 39 may be coupled to a wedge 38 below each of the cutting members.
  • the tilt- Q. ability of the shear plate 33 is obtained in known manner by means of the multiple-bent shaft 40 which is also maintained in the stop position.
  • a dry shaver having a housing comprising a shaving head provided with an opening therein, a shear plate adapted to move vertically in said opening, a driven blade in said opening under said shear plate, spring means in said shaving head for biasing said. driven blade against said shear plate, a shaped stop member for adjustably selecting a lower abutting limit for various depths of depression of said shear plate against said spring means, and an operating means extending outside said housing for adjusting said lower abutting limit of said shear plate.
  • a dry shaver as claimed in claim 1 further comprising inclined surfaces on the lower edge of said stop member, and corresponding inclined surfaces on said shaving head on which the inclined surfaces of said stop member rests whereby the rotation of the latter in one direction by said operating means causes said stop member to adjustably select said lower abutting limit for various depths of depression of said shear plate against said spring means.
  • a dry shaver comprising a shaving head provided with an opening therein, a shear plate adapted. to move vertically in said opening and having a supporting rim, a driven blade in said opening under said shear plate, spring means in said shaving'head for biasing said driven lade against said shear plate, a shaped stop member in said opening and in operative engagement with said shear plate for adjustably selecting a lower abutting limit for said shear plate for various depths of depression of said shear plate against said spring means, a shaped stop member for adjustably selecting a lower abutting limit for various depths of depression of said shear plate against said spring means, and an operating means extending outside said housing for adjusting said lower abutting limit of said shear plate, said shaped stop member being provided with a series of teeth, the tips of which are located in one plane, and said tips collectively constituting a stop for the supporting rim of said shear plate.
