With Relative Blade And Guard Adjustment Patents (Class 30/79)
  • Patent number: 11780107
    Abstract: An apparatus is provided that includes a knife and blade cover. The knife includes a handle and a blade. The handle is attached to the blade. The blade includes a cutting edge, a cheek, and an upper spine. The cheek extends between the cutting edge and the upper spine. The apparatus further includes a blade cover. The blade cover covers opposite sides of the cutting edge of the blade. The blade cover covers at least a portion of the upper spine in a stowed position. The apparatus further includes a biasing device. The biasing device is in operative connection with the knife and the blade cover. The biasing device is operative to bias the blade cover down against the upper spine in the stowed position. The blade is in operative connection with the knife. The blade cover is operative to move relative to the blade in a direction away from the cutting edge when the blade cuts an object to enable the blade to cut the object.

  • Publication number: 20080196252
    Abstract: To provide a hair cutting device permitting the user to really know the remaining hair length without having to do trial cuts, a hair cutting device (1) with hair length indicator means (4) is proposed, wherein the hair length indicator means (4) comprises a fixed delimiter (5) and at least one movable delimiter (6) being movable with respect to the fixed delimiter (5), such that the hair length is indicated by the distance (D) between the fixed (5) and the at least one movable delimiter (6). Preferably, the hair length indicator means (4) comprises more than one movable delimiter (6, 7), all movable delimiters (6, 7) being movable in circumferential direction and functionally couplable with a comb unit (19, 20) such that a change between movable delimiters (6, 7) is caused by attachment of the comb unit (19, 20) to the hair cutting device (1).

  • Patent number: 6249973
    Abstract: A mechanical thinning razor includes a shank, a handle, a blade, a bladeguard, a driving member and a sliding member. When pushing an external surface of the driving member toward a hollow midsection of the shank, the bevel of the driving member forces the sliding member to move longitudinally over a distance that corresponds to a width of exposed segments or non-exposed segments, thereby doubling the working life of the blade.

  • Patent number: 5084969
    Abstract: A razor head is provided that is disposed at the front end of a handle of a wet razor. The razor head includes a body in which is disposed a single or double razor blade. A guide strip that extends parallel to the razor blade is disposed in front of the same and is furthermore disposed on a displacement mechanism or a pivot mechanism in such a way that in a direction perpendicular to a lengthwise dimension of the guide strip, the latter is freely movable counter to a spring force. This allows the shaving angle and hence the cutting geometry to be altered in a straighforward manner.
