Definitions

  • ABSTRACT An improvement in hair guiding and skin stretching means mounted on a shaver having a cutter which contacts the users skin as the shaver is moved in a hair shearing path across the users skin.
  • the improvement includes a first member, for combing hair and stretching skin, in combination with a second member, for lifting hair and stretching skin.
  • the first and second members are connected alongside of the cutter to contact the skin ahead of the cutter as the shaver is advanced in the hair shearing path of movement across the users skin, the first member stretching the skin and combing the long hair in advance of the sec- 0nd member, and the second member further stretching the skin and lifting the short hairs from the surface of the skin in advance of the cutter.
  • This invention is concerned with a shaver including a cutter head having cutter teeth, which is provided with means for guiding the hairs toward the cutter teeth, while preventing attendant irritation to the users skin. More particularly, the invention is concerned with an improvement for combing and lifting hairs into the hair shearing path of the cutter teeth, and stretching the users skin to prevent entry thereof into the hair shearing path.
  • a cutter head of the type here being considered includes one or more elongated outer cutters and a corresponding number of elongated inner cutters mounted for reciprocation within the outer cutters.
  • the outer cutters each have an inverted U-shaped cross-section, and have a plurality of parallel transverse slots formed in the upwardly disposed mid-portion thereof, to define a plurality of parallel cutter teeth in the mid-portion.
  • the inner cutters have a hollow rectangularly-shaped cross-section and have a plurality of parallel cutter teeth in the upper side.
  • the inner cutters are each mounted within one of the outer cutters, with their respective cutter teeth upwardly oriented and slidably engaged in hair shearing relationship with one another, and provision is made for the inner cutters to be reciprocated by the motor of the shaver.
  • the mid-portions of the outer cutters and thus the outer surfaces of the outer cutter teeth normally contact the users skin as the shaver is moved in a hair shearing path across the users skin.
  • Most users tend to press the outer cutters against their skin with considerable force, in an effort to cause the hair bristles protruding from the skin to enter into the slots between the outer cutter teeth for shearing by the inner cutter teeth.
  • the users skin may be caused to bulge inwardly of the slots of the outer cutters and come into contact with the inner cutters, thus causing the skin to be irritated by the inner cutters.
  • the bulging takes place to a greater or lesser extent depending on the width of the slots and the force with which the user presses the outer cutters against his skin.
  • the widths of the outer cutter slots are normally reduced as much as technology will allow without also preventing hairs from entering the slots.
  • skin stretching members having hair lifting characteristics have been mounted alongside and parallel to the leading edges of the outer cutters. Such members are designed to enable the user to force the skin taut in advance of contacting the outer cutters. Thus stretching the skin renders the skin less able to be forced into contact .with the inner cutters, and lifting the hairs promotes entry thereof into the shearing path of the inner cutters. See, for example,
  • the aforesaid type of skin stretching member is normally provided with either a sharply angled leading edge or a roughened upper surface, or both, for elevating the free ends of the hairs from the surface of the skin as the member is moved thereacross.
  • the typical member is useful for guiding short hairs into the slots of the outer cutter, the members leading edge or outer surface may be pressed against the skin with sufficient force to scrape the surface of the skin.
  • an object of this invention is to provide a shaver for shearing hairs without attendant irritation to the skin.
  • Another object is to provide a shaver including improved means for stretching the skin and guiding the hair.
  • Another object is to provide an improved shaver including means for first stretching the skin and combing hair and then stretching the skin and lifting hair.
  • a further object is to provide means for successively stretching the skin in the path of movement of the outer cutter of a shaver and combing and lifting hairs protruding from the stretched skin for entry into the hair reception slots between the teeth of the outer cutter, whereat the hairs are disposed in the hair shearing path of the inner cutter.
  • a still further object is to provide a shaver including means for stretching the skin and combing long hairs and thereafter stretching the skin and lifting short hairs from the surrace thereof, the hair thus being guided toward the hair shearing path of the cutter teeth of the shaver.
  • the present invention provides an improved shaver including means for preventing the skin from contacting the inner cutters and guiding hairs into the slots between the teeth of the outer cutter for shearing by the inner cutter.
  • the improved shaver has first and second elongated skin stretching members, the first of which includes means for combing long hair into the hair re ception slots of the outer cutter and the second of which includes means for lifting short hairs from the surface of the skin for entry into the aforesaid hair reception slots.
  • the first and second members are mounted alongside and'parallel to one another and to the leading edge of the outer cutter, such that the first member is the first to contact a given area of skin in the hair shearing path of movement of the shaver, followed by the second member and then the outer cutter.
  • the first member stretches the skin and combs the longer hair protruding from the skin area, and the second member thereafter further stretches the skin area and lifts the shorter hairs from the surface thereof, for engry into the hair reception slots of the outer cutter.

  • the cutter head units 21, 22 and 23 are mounted alongside and parallel to one another on a cutter head frame 24.
  • the frame 24 includes a base plate 45 having a top portion 46, on which the base spacers 28 of the outer cutters 25 are mounted, and depending side walls 47.
  • the base spacers 28 are fixedly connected by known means to the top portion 46 of the base plate 45,
  • the depending side walls 47 of the base plate 45 may be removably connected to a motor housing 48 by means of resilient clips 49, extending laterally from the motor housing 48.
  • the upper sides 36 of the inner cutters 35 are urged upwardly into sliding engagement with the undersides of the mid-portions 26 of the associated outer cutters 25, in a known manner, for example, by means of leaf springs 50.
  • the respective inner cutter teeth 42 are thus resiliently urged into cutting engagement with the outer cutter teeth 32 with which they are adjacently associated.
  • Each of the leaf springs 50 is connected to the lower side 38, of an inner cutter 35, and seated on a drive arm 52.

  • the drive arms 52 are adapted to be driven by a motor (not shown), which is housed in a suitable manner within the motor housing 48, the latter being supported in place within the shaver casing 12 by means well known in the art.
  • a motor not shown
  • the drive arms 52 reciprocate the springs 50, and thus the inner cutters 35 relative to the outer cutters 25, thereby slidably moving the inner cutter teeth 42 in cutting cooperation with the adjacently associated outer cutter teeth 32.
  • the uppermost surfaces of the cutter head 20, and thus the outer surfaces of the mid-portions 26 of the respective outer cutters 25, are pressed against and moved across the users skin, in the direction of orientation of the outer cutter slots 30.
