Definitions

  • the invention relates to a dry-shaving apparatus having a shear plate which is displaceable in the axial direction and a movable cutting member which cooperates with the shear plate and supports it, this cutting member being rigidly journalled in the axial direction at least at a pressure exceeding a given value.
  • lt is an object of the invention to overcome this disadvantage while retaining the possibility for the user to adjust the pressure ybetween the shear plate and the cutting member.
  • the cutting member and the shear plate are urged toward one another by resilient means, even when no pressure is exerted on the shear plate.
  • the shear plate is held by resilient means against a cutting member which is rigidly journalled in the axial direction.
  • the cutting member is arranged so as to be movable in the axial direction only through a certain distance and is held to 'the shear plate by resilient means.
  • the resilient means can be incorporated in the driving means of Ithe cutting member in the usual manner, care must be taken only to ensure that a stop limits the movement of lthe cutting member in the axial direction.
  • the resilient means may lin this case be so proportioned that the cutting member is rigidly journalled when the force pushing it inward exceeds about 40 grams.
  • Fig. 1 is a sectional view of a shaving apparatus in accordance with the invention, the shear plate being depressed.
  • Fig. 2 is a sectional view of an alternate embodiment of the invention.
  • a shear plate 1 is displaceable in the axial direction between stops 2 and 3.
  • a cutting member 4 co-operates with the shear plate 1 and supports it. In the axial direction, the cutting member 4 bears by means of 2,952,908 Patented Sept. 20, 1960 Mice a spindle 5 upon a driving shaft 6 which is displaceable in a toothed wheel 7 in the axial direction but is coupled thereto in the direction of rotation.
  • the toothed wheel 7 is rigidly journalled in the apparatus in the axial direction and internally provided with a stud 8 having a pointed end which corresponds to a recess 9 in the end of the driving shaft 6.
  • the stud 8 is surrounded by a helical spring lil which is arranged between the driving shaft 6 and the toothed wheel 7 and tends to thrust the shaft upwards. It should be noted from examining the drawings that when the shear plate 1 is depressed to its most inward position the spindle 5 is rockable in slot 13 of driving shaft 6.
  • the shear plate 1 When the shear plate 1 is applied to the skin under normal pressure, the helical spring 10 is compressed until the position shown in Fig. l is reached.
  • the force which the helical spring 10 can absorb is about 40 grams.
  • the helical spring 10 may alternatively be replaced by resilient elements 12 as seen in Fig. 2 arranged between the stop 2 and a rim -11 of the shear plate 1.
  • a dry shaver comprising a casing, a shear plate, means mounting said shear plate in said casing for limited axial movement, a cutting member, means mounting said cutting member for movement in the direction of its longitudinal axis as well as rotational movement, said shear plate being supported only by said cutting member in the most inwardly depressed position of the shear plate, and resilient means operatively connected to the cutting member and adapted to maintain said cutting member in supporting engagement with said shear plate.
  • a dry shaver comprising a casing, a shear plate, means mounting said shear plate in said casing for limited axial movement, two spaced stop members for said shear plate, a cutting member, means mounting said cutting member for movement in the direction of its longitudinal axis as well as rotational movement, said means including a two-part drive shaft having one pant mounted for limited movement in an axial direction thereof, and a spring connecting one part of the drive shaft to the other part, said one part being movable in the direction of its longitudinal axis to abut the other part of the drive shaft before said shear plate contacts one of said stop members, said spring adapted to maintain said cutting member in supporting engagement with said shear plate.
  • a dry shaver comprising a casing, a shear plate, means mounting said shear plate in said casing for limited axial movement, a cutting member, means including a drive shaft .and a spindle mounting said cutting member for movement yin the direction of its longitudinal taxis as well as rotational movement, said shear plate being supported only by ⁇ said cutting member in the most inwardly depressed position of the shear plate, and resilient means operatively connected to the cutting member and adapted to maintain said cutting member in supporting engagement with Said shear plate, said spindle being rockable on said drive shaft and carries said ⁇ shear plate and cutting member along therewith.
