Abstract
An electric razor with round external cutting members and round internal cutting members with cutters at the end of uneven length arms. Each one of the external cutting members has concentric circular shaving sections obtained by concentric grooves, and the backs of the circular shaving sections are defined as tracks so that cutters of the internal cutting member are rotated in the tracks. The external cutting member is formed with slits which are substantially in a radial direction and uneven in the length.
Claims11
An electric razor comprising an external cutting member, which is provided with radial slits for bringing hair under a round shaving surface, and an internal cutting member which is for cutting said hair that is led through said slits while sliding along an inner surface of said external cutting member;
- wherein
- said round shaving surface is divided into concentric plural sections via one or more circular partition grooves provided concentrically with a center of said shaving surface;
- said external cutting member is integrally formed as one integral unit;
- and
- said slits are opened at predetermined intervals in surfaces ranging from an outermost shaving section to an innermost shaving section and through said partition grooves, and said slits are further opened between each of said opened slits so as to be formed in the range up to an innermost partition groove or up to a partition groove located outside said innermost partition groove.
An electric razor comprising a plurality of external cutting members and a plurality of internal cutting members, in which:
- a round top of each one of said external cutting members is divided into three concentric circular shaving sections via two circular grooves formed concentrically with a center of said external cutting member, the backs of said three shaving sections being defined as circular tracks;
- each of said plurality of said external cutting members is integrally formed as a unitary member;
- first slits for hair entry are opened on said round top at predetermined intervals in a circumferential direction of said internal cutting member, said slits being opened so as to cross said three shaving sections and said two circular partition grooves;
- second slits for hair entry are opened on said round top at predetermined intervals in a circumferential direction of said internal cutting member, each one of said second slits being opened between said first slits and crossing outer two concentric circular shaving sections and an outer circular groove;
- third slits for hair entry are opened at predetermined intervals in a circumferential direction of said external cutting member, each one of said third slits being opened between one of said first slits and one of said second slits and crossing only an outermost shaving section;
- said internal cutting member is provided with cutters at ends of arms extending outwardly in three different length so that said cutters fit in said three circular tracks of said external cutting member;
- and
- said internal cutting member is integrally formed as one member.
