Definitions

  • This invention relates to a hair-clipping head comprising a housing, a driven blade, a knife-edged comb and spring pressure means pressing the blade against the comb. Specifically, it is concerned with the spring pressure means and the mounting means therefor.
  • the spring pressure means include wire springs, one of each wire spring being mounted in a sliding member which is molded onto the end and is pivotally mounted on a lug provided on a retaining member securing the comb. Each of the other ends of the wire springs engage in a cavity provided on the driven blade.
  • the invention relates to hair-clippers, and particularly to a hair-clipping head, provided with a housing and a driven blade which is pressed by spring pressure against a knife-edged comb.
  • the spring pressure is applied by a spiral spring the two ends of which are supported by the blade, and the intermediate part of which is secured in position in the housing.
  • This construction has the particular disadvantage that during the cutting movement the drive of the blade has to overcome the resistance of the spring.
  • the individual springs are pivotally mounted at least in the housing.
  • the end of the spring on the housing side is advantageously secured in position in a sliding member which is pivotally mounted on a lug provided on the housing or on a retaining member connected to the housing.
  • the sliding member is molded onto the end of the spring on the housing side and is made of a synthetic resin.
  • the spring may be a leaf spring or a bow spring, a wire spring being preferably used.
  • the construction according to the invention affords the particular advantage that the driving force is not counteracted by the force by which the blade is resiliently guided.
  • FIGURE 1 shows a part-sectional plan view
  • FIGURE 2 shows a part-sectional side view of hairclippers according to the invention without the housing.
  • the hair-clippers or the hair-clipping head illustrated by way of example in the drawings consists essentially of a housing 1, a retaining member 2, a knife-edged comb 3, and a blade 4.
  • the knife-edged comb 3 is secured to the retaining member 2 by means of two screws 5 and two nuts 6, each screw passing through a tubular lug 7 provided on the retaining member 2.
  • the retaining member 2 is provided with two forwardly extending arms 8 adjacent the blade and two rearwardly extending arms 9, the ends of the arms 9 engaging respectively in corresponding grooves provided on the inside of the housing, whereas the rear end of the fixed knife-edged comb 3 contacts the outside of the housing.
  • the blade rests on the knife-edged comb 3 in bridgelike manner, since both these members are provided with recesses 10 or 11, the surfaces of which face each other.
  • the blade 4 is guided and pressed against the knife-edged comb 3 by two springs 12.
  • the springs 12 are constructed as wire springs, their ends on the housing side being secured in position in annular sliding members 13, which are rotatably or pivotally mounted on the tubular lugs 7 provided on the retaining member 2.
  • the axial length of the lugs 7 exceeds that of the sliding members 13, as the latter are not clamped by the nuts 6.
  • the ends of the wire springs 12 on the housing side are preferably mounted in the annular sliding members 13 which are molded onto said ends and are made of a synthetic resin.
  • the ends of the springs 12 on the blade side are bent in the direction of the blade 4 and rest on the blade or engage in cavities, for example bores, provided in the blade.
  • the intermediate section of the bowor U-shaped spring 12 may be provided with a loop 14.
  • the blade 4 is driven by a structural part 15 the end of which is connected to the knife by two hollow rivets 16.
  • the blade 4 and the knife-edged comb 3 are preferably made of cold-rolled strip steel, whereas the retaining member 2, the sliding member 13, and the structural part 15 are made of a synthetic resin, such as acetal resin, or of the type known by the registered trade mark Delrin.
  • the replaceable housing 1 is preferably secured to a member containing the driving means, and is preferably also made of a synthetic resin, such as cellulose acetate.
  • a hair-clipping head comprising a housing, a driven blade provided with cavities, a retaining member having lugs and mounted on said housing, a knife-edged comb secured to said retaining member, sliding members made of a synthetic resin and spring pressure means including individual wire springs, said driven blade being pressed by said wire springs against said knife-edged comb, each of said sliding members being molded onto one end of one of said wire springs and being pivotally mounted on one of said lugs and each of the other ends of said wire springs engaging in one of said cavities provided on said driven blade.
  • each of said sliding members is of an annular section.
