Abstract
A shaving implement includes a grip portion, a transversely extending support portion at one end of the grip portion, a connection between the grip portion and the support portion which permits movement of the support portion relative to the grip portion during the course of a shaving stroke in a dynamic mode of shaving action, and structure for restricting the movement of the support portion relative to the grip portion, the movement restricting structure including a control portion movable between a first position which affords significant movement restriction and a second position which affords less movement restriction.
Claims20
A shaving implement comprising a grip portion,
- a transversely extending support portion at one end of said grip portion, said support portion defining a blade edge position, a connection between said grip portion and said support portion mounting said support portion for angular rotational movement relative to said grip portion during the course of a shaving stroke in a dynamic mode of shaving action about an axis extending transversely of said support portion parallel to and adjacent to said blade edge position, said connection including structure in said transversely extending support portion defining said axis at a point spaced further from said grip portion than portions of said transversely extending support portion,
- and structure for restricting the movement of said support portion relative to said grip portion, said movement restricting structure including a control portion movable between a first position which affords significant restriction of angular rotational movement and a second position which affords less restriction of angular rotational movement.
A shaving implement comprising a grip portion,
- a transversely extending support portion at one end of said grip portion, a connection between said grip portion and said support portion which permits movement of said support portion relative to said grip portion during the course of a shaving stroke in a dynamic mode of shaving action, two leaf spring members providing two opposed restoring forces tending to maintain said support portion in preferred orientation relative to said grip portion where said restoring forces are balanced,
- and structure for restricting the movement of said support portion relative to said grip portion, said movement restricting structure including a control portion movable between a first position which affords significant movement restriction and a second position which affords less movement restriction.
A shaving implement comprising a grip portion,
- a transversely extending support portion at one end of said grip portion, said support portion defining a blade edge position, a connection between said grip portion and said support portion mounting said support portion for angular rotational movement relative to said grip portion about an axis extending transversely of said support portion parallel to and immediately adjacent to said blade edge position during the course of a shaving stroke in a dynamic mode of shaving action,
- and structure for restricting the movement of said support portion relative to said grip portion, said movement restricting structure including an actuator member carried by said grip portion and a control portion responsive to said actuator member and movable between a first position which affords significant restriction of angular rotational movement and a second position which affords less restriction of angular rotational movement, said control portion in said first position being inserted into a recess in said support portion for locking said support portion relative to said grip portion.
A shaving implement comprising a grip portion,
- a transversely extending support portion at one end of said grip portion, a connection between said grip portion and said support portion which permits movement of said support portion relative to said grip portion during the course of a shaving stroke in a dynamic mode of shaving action, said connection including juxtaposed, spaced, inner and outer, arcuate bearing segments, each said bearing segment being less than 180.degree. in angular extent, and a cooperating hollow shaft segment also of less than 180.degree. in angular extent, the inner and outer surfaces of said hollow shaft segment being received in bearing engagement with said inner and outer bearing segments, said interengaged bearing segments and shaft segment defining an axis of rotation of said support portion located immediately adjacent the active elements of the shaving system and extending parallel to the cutting edge of the shaving implement
- and structure for restricting the movement of said support portion relative to said grip portion, said movement restricting structure including a control portion movable between a first position which affords significant movement restriction and a second position which affords less movement restriction.
A shaving implement comprising a grip portion,
- a transversely extending support portion at one end of said grip portion, said support portion defining a blade edge position, a connection between said grip portion and said support portion mounting said support portion for angular rotational movement relative to said grip portion about an axis extending transversely of said support portion parallel to and immediately adjacent to said blade edge position during the course of a shaving stroke in a dynamic mode of shaving action, restoring structure for generating a force when said support portion is offset from a position of neutral orientation relative to said grip portion tending to move said support portion towards said position of neutral orientation, said restoring structure including two elongated spring members for providing two opposed restoring forces tending to maintain said support portion in a normal position where said restoring forces are balanced, said elongated spring members extending between said grip and support portions,
- and structure for restricting the movement of said support portion relative to said grip portion, said movement restricting structure including a control portion movable along a path generally parallel to said elongated members between a first position which affords significant restriction of angular rotational movement and a second position which affords less restriction of angular rotational movement, an actuator member carried by said grip portion and mounted for rotational movement, a cooperating spring member for stably maintaining said actuator in a selected position, said control portion being responsive to said actuator member and said second position being spaced further from said support portion than said first position.
