Abstract
A dryshaving apparatus in which a shaving head and an oscillating-armature motor constitute an assembly. This assembly is mounted in the housing of the dryshaving apparatus by elastic elements only, at least one elastic element being a strip-shaped integral hinge extending transversely to the oscillating movement and connected at one end to the assembly and at its other end to the housing. The assembly together with the elastic elements has a mechanical resonant frequency less than the oscillation frequency, divided by .sqroot.2, of the parts of the assembly performing the oscillating movement.
Claims5
A dryshaving apparatus which comprises a housing;
- a shaving head including a stationary upper cutter and a cooperating lower cutter;
- an oscillating armature motor for driving the lower cutter in a reciprocatory oscillating movement, the shaving head and the oscillating-armature motor being connected and constituting an assembly;
- and means to mount the assembly in the housing by elastic elements only, at least one of the elastic elements being a strip-shaped integral hinge extending transversely to the oscillating movement, said integral hinge being connected at one end to the assembly and at its other end to the housing, the assembly together with the elastic elements having a mechanical resonant frequency less than the oscillation frequency, divided by .sqroot.2, of the parts of the assembly performing the reciprocatory oscillating movement.
