Abstract
Shaving apparatus having at least one pivotable cutting unit ( ) comprising an external cutting member ( ) and an internal cutting member ( ) which is drivable relative to said external cutting member, a drive mechanism ( ) for driving said internal cutting member ( ) into rotation, and a coupling member ( ) having a coupling head ( ) and a coupling body ( ), which coupling head can be coupled to a coupling element ( ) of the internal cutting member ( ) in a detachable manner, said coupling body ( ) being coupled to said driving mechanism ( ). The coupling head ( ) can be inserted into a cavity ( ) of the coupling head ( ). For driving said internal cutting member into rotation, the coupling head ( ) comprises curved surfaces ( ) for cooperation with surfaces ( ) of said cavity ( ). To improve the drive system, the coupling head ( ) and the cavity ( ) of the coupling element ( ) have an approximately triangular shape which is rotationally symmetrical through 120°, as seen in the direction of the axis of rotation ( ) of the coupling head ( ).
