Definitions

  • the embodiments of the present invention described below are so arranged that a substantially similar blade geometry can be achieved although such geometry does not apply when the blade unit is at rest and not in use.
  • the guard 2 is mounted to the frame for up and down sliding movement between upper and lower end positions defined by stop surfaces provided on the frame.
  • the guard is urged lightly to the upper end position by a spring 20.
  • the cap 3 is similarly ⁇ lidably mounted by the frame for up and down movement between end positions defined by stops, and a spring 21 lightly biases the cap to its upper end position.
  • an upwardly facing shoulder 30 on the guard abuts a stop surface 31 defined by a flange 32 integral with the frame, as seen in Fig. 2.
  • the second blade would have intermediate values or values that are the same as the third blade in order to promote the progressive force pattern.
  • the spring preloads are typically in the range of about 25g or less.
  • the force on the individual blades would be expected to be in the range of about 0-40g, with between zero and 20 gms on the first blade, and between greater than zero and lees than 40 gms on the third blade. Typically the forces on the individual blades would be greater than 5gm. At rest exposures and exposures during shaving typically are in the ranges noted earlier.
