Claims13
A shaver set comprising:
- a plurality of electric shavers, each shaver comprising:
- a handle comprising a housing,
- a motor received in said housing,
- a shaver head connected to said handle by a support structure mounted to connector elements of said housing,
- at least one cutter unit provided on said shaver head and including a cutter element and a shearfoil, wherein said cutter element is configured to be driven along a cutter oscillation axis by said motor via a drive transmitter extending from said housing, past the connector elements of said housing and into the support structure connecting said motor to said cutter element,
- wherein the housings of all electric shavers including the drive transmitters supported by said housings and the connector elements of said housings are identical to each other, wherein the identical structure of the connector elements of all housings matches with the support structure of each shaver head,
- wherein
- the shaver heads and the support structure thereof are different from each other, wherein the following three types of support structures are included:
- a first support structure configured to provide for a swivel axis and a tilting axis about which a corresponding said shaver head may swivel and tilt relative to said associated handle, a second support structure configured to provide for only a swivel axis about which a corresponding said shaver head may swivel relative to said associated handle, and
- a third support structure configured to rigidly hold a corresponding said shaver head relative to said associated handle.
A method of manufacturing a shaver set comprising a plurality of electric shavers, each shaver comprising a handle having a housing, a shaver head including at least one cutter unit comprising a shearfoil and a cutter element drivable under said shearfoil along a cutter oscillation axis, and a motor connected to said cutter element via a drive transmitter, the method comprising:
- a) manufacturing, for each of said electric shavers, a corresponding said housing for containing the motor and supporting the drive transmitter, the drive transmitter extending from said housing, past connector elements of said housing and into a support structure for a corresponding said shaver head, a portion of said housings containing and fully enveloping the motor and supporting the drive transmitter, being identical to each other and having the connector elements for connecting the support structure of each of the shaver heads to said housing, with all housings of all shavers of the shaver set having the identical structure of connector elements,
- b) manufacturing, for each of the electric shavers, a support structure for connecting the shaver head to said housing,
- wherein said support structures include the following three support structures:
- a first support structure configured to provide for a swivel axis and a tilting axis about which said corresponding shaver head may swivel and tilt relative to said associated housing,
- a second support structure configured to provide for a swivel axis about which said corresponding shaver head may swivel relative to said associated handle, and
- a third support structure configured to rigidly hold the corresponding shaver head non-moveable relative to the associated housing,
- wherein the support structures of all shaver heads are manufactured to match the connector elements of all housings of all electric shavers of the shaver set.
A shaver handpiece of an electric shaver, wherein said shaver handpiece comprising a handle having a housing, a motor received in said housing, a drive transmitter connected to said motor and including a drive shaft having a shaft portion extending outside of said housing, said shaft is driven by said motor to rotate in a reciprocating manner, wherein said housing is provided with connector elements for connecting a shaver head to the handle, wherein
- said housing comprises an inner housing portion receiving said motor and an outer housing portion surrounding said inner housing portion, the outer housing portion comprising shell elements positioned on opposite sides of the inner housing portion, wherein said connector elements for connecting the shaver head are provided on said inner housing portion and include joints providing for a pair of pivot axes extending transverse to the longitudinal axis of the drive shaft and positioned on opposite sides of the drive shaft, wherein said joints are positioned in place at said inner housing portion.
