Abstract
A shaving device comprising a head assembly having a support member and a blade cartridge. The support member is configured to be detachably coupled to a handle. The blade cartridge has a first and a second face wherein at least one of the first or second faces comprises at least one razor blade. The blade cartridge is configured to be rotatably coupled to the support member about a pivot axis such that the blade cartridge is pivotable by a user to select one of the first or second faces.
Claims30
A shaving device comprising:
- a head assembly comprising:
- a support member configured to be detachably coupled to a handle;
- a blade cartridge having a first and a second face wherein at least one of said first or second faces comprises at least one razor blade, said blade cartridge being configured to be rotatably coupled to said support member about a pivot axis such that said blade cartridge is pivotable by a user to select one of said first or second faces;
- and
- a resistive pivot mechanism configured to allow a user to rotate said blade cartridge about said pivot axis to select one of a first or a second face position corresponding to said first and second faces of said blade cartridge, respectively, said resistive pivot mechanism configured to allow said blade cartridge to rotate both clockwise and counter-clockwise within a predefined rotation range while at said selected face position, wherein said resistive pivot mechanism comprises at least one resiliently deformable pawl configured to engage one of a first and a second recess corresponding to said first and second face position, respectively.

A shaving device comprising:
- a head assembly comprising:
- a support member configured to be detachably coupled to a handle, said support member comprising a first and a second support arm comprising a first and a second pivot receptacle;
- a blade cartridge having a first and a second face wherein at least one of said first or second faces comprises at least one razor blade extending generally parallel to a longitudinal axis of said blade cartridge, said blade cartridge further comprising a first and a second pivot pin extending outwardly from opposing lateral sides of said blade cartridge along a pivot axis of said blade cartridge, said pivot axis extending generally parallel to said longitudinal axis of said blade cartridge, wherein said first and said second pivot pins are configured to be rotatably coupled to said first and said second pivot receptacles, respectively, such that said blade cartridge may be rotated about said pivot axis to select a first or a second initial starting position corresponding to said first or said second face, respectively;
- and
- a resistive pivot mechanism configured to allow a user to rotate said blade cartridge about said pivot axis to select one of a first or a second face position corresponding to said first and second faces of said blade cartridge, respectively, said resistive pivot mechanism configured to allow said blade cartridge to rotate both clockwise and counter-clockwise within a predefined rotation range while at said selected face position, wherein said resistive pivot mechanism comprises at least one resiliently deformable pawl configured to engage one of a first and a second recess corresponding to said first and second face position, respectively.

A method for using a razor, said method comprising:
- rotating a blade cartridge coupled to a support member about a pivot axis against a resistive pivot mechanism to select one of a plurality of faces of said blade cartridge, wherein at least one of said plurality of faces includes at least one razor blade;
- applying a first force in a clockwise direction against said resistive pivot mechanism to rotate said blade cartridge clockwise within a predefined rotation range while at said selected face position;
- and
- applying a second force in a counter-clockwise direction against said resistive pivot mechanism to rotate said blade cartridge counter-clockwise within said predefined rotation range while at said selected face position;
- wherein said resistive pivot mechanism comprises at least one resiliently deformable pawl configured to engage one of a first and a second recess corresponding to said first and second face position, respectively.
