Abstract
An electric dry shaver of reciprocally vibrated type having long hair trimmer which is driven only when a coupling member mounted to drive means is coupled to clipper cutter of the trimmer by trimmer operating handle manually operated. The clipper cutter has a joint member and the coupling member is normally biased away from engagement with the joint member. The handle as operated into trimmer operating position engages the coupling member to urge it into engagement with the joint member so that the clipper cutter will be coupled to the drive means.
Claims6
An electric dry shaver comprising a main shaving blade assembly of an outer shearing blade provided in a frame of shaver body and an inner cutter blade provided slidably in contact with inner surface of said outer shearing blade, a trimmer blade assembly of a comb blade fixed to the shaver body and a clipper cutter blade slidable along said comb blade, a driving means for providing a reciprocating motion to said cutter blade of main shaving blade assembly, a coupling means rotatably pivoted to said driving means for moving always together with the driving means, and a handle fitted to the shaver body so as to be movable between engaging and disengaging positons with said coupling means, said coupling means being rotated to engage with said clipper cutter blade of the trimmer blade assembly only when said handle is moved into said engaging position with the coupling means so that the coupling means will transmit the reciprocating motion of the driving means to the clipper cutter blade.
An electric dry shaver comprising a shaver body including a motor, a main shaving assembly formed of an outer shearing blade secured to the shaver body and an inner cutter blade, an oscillating drive member having its input coupled to the motor and its output coupled to the cutter blade for reciprocating the same, a trimmer blade assembly including a comb blade secured to the shaver body substantially at right angles to the oscillation axis and a clipper blade slidable therealong, means for selectively coupling together the drive member and the clipper blade, the coupling means having a first part and a second part with respective interengageable surfaces, one of the parts being mounted on the drive member for bodily oscillation therewith and the other part being connected to the trimmer blade, the first part being in the form of a rockable member rockable about an axis substantially at right angles to the oscillation axis between (a) a retracted position in which the surfaces are out of engagement and (b) a projecting position in which the surfaces are in engagement accompanied by reciprocation of the trimmer blade, a cam follower surface on the rockable member, a cam mounted on the body and manually shiftable between a "trimmer off" position in which the rockable member is in its retracted position and a "trimmer on" position in which the cam engages the cam follower surface to rock the rockable member into its projecting position for interengagement of the surfaces for reciprocation of the trimmer by the drive member.
