Abstract
A rotary electric shaver includes a handle assembly having a housing, a motor disposed in the housing, a drive shaft operatively connected to the motor and extending through the housing, and a socket for securing a shaver head thereto. The shaver head assembly includes a coupling for detachable coupling to the socket. The coupling is configured to allow the shaver head to be detachably coupled to the handle assembly in at least two different orientations of the shaver head relative to the handle assembly.

A rotary electric shaver comprising:
- a handle assembly including a housing, a motor disposed in the housing, and a drive shaft operatively connected to the motor and extending through the housing, and a socket for securing a shaver head thereto, and
- the shaver head assembly including a coupling for detachable coupling to the socket, the coupling configured to allow the shaver head to be detachably coupled to the handle assembly in at least two different orientations of the shaver head relative to the handle assembly.
A detachable shaver head assembly for a rotary electric shaver, the rotary electric shaver having a handle including a housing, a motor, and a drive shaft accessible by the shaver head assembly exterior of the housing, the shaver head assembly being positionable on the handle assembly and comprising:
- a coupling for detachable coupling to a complimentary socket of the handle, the coupling configured to allow the shaver head to be detachably coupled to the handle assembly in at least two different orientations of the shaver head with respect to the handle assembly.
A method of positioning a detachable shaver head on a rotary electric shaver handle, the rotary electric shaver having a handle including a housing, a motor, and a drive shaft accessible by the shaver head assembly exterior of the housing,
- aligning a coupling of the shaver head with a complimentary socket of the handle, the coupling configured for aligning with the socket in at least two different orientations of the shaver head with respect to the handle,
- pressing the coupling to the socket such that the coupling is detachably coupled to the socket, and the drive shaft engages with a drive coupling of the shaver head.
