A shaving apparatus, shaving head and/or at least one cutting unit for shaving both short and long hairs. The shaving apparatus, shaving head and/or at least one cutting unit includes an external cutting member and an internal cutting member movably arranged with respect to the external cutting member. A driver may be provided for moving the internal cutting member. The external cutting member is provided with a shaving section having two mutually connected lateral borders forming hair entry apertures. The internal cutting member is provided with cutting elements having cutting edges for cooperation with cutting edges of the external cutting member. A number of the hair entry apertures are formed by two substantially flat lamellae of the external cutting member which have free ends positioned between the borders of the shaving section.

Shaving apparatus, a cutting unit and a shaving head

Shaving apparatus, a cutting unit, and a shaving head

A shaving apparatus with an external cutting member () and an internal cutting member which can be driven into rotation relative to the external member. The external cutting member () has an annular region () with hair-trapping apertures () and a skin support region () in a central area surrounded by the annular region. To improve the shaving performance, the skin support area is provided with ridges

Shaving apparatus

The invention relates to an electrically driven shaving apparatus of the type having a reciprocating cutter ( ). The cutter is situated in a shaving head ( ) which is freely pivotable between two positions. The shaving apparatus also comprises a trimmer ( ), which is movable from a non-driven rest position ( ) into a driven operating position ( ). In this operating position the shaving head ( ) is pivoted away into a locking position ( ), in which position the cutter ( ) is not driven. The advantage is that all the motor power is available for driving the trimmer.

Electric shaving apparatus

A shaving apparatus has a head assembly (2) which houses rotary cutters (8), and guards (4) which are provided with an annular series of hair-entry apertures (6). A fixed supporting surface is provided inside and outside the ring of apertures, to provide support when shaving with large applied pressure.

A shaving apparatus is provided having a housing provided with a holder for at least one shaving unit, which shaving unit comprises an external shaving member with hair entry apertures and an internal shaving member which is rotatable relative to the external shaving member, which internal shaving member is coupled to a drive mechanism by means of a drive shaft, which shaft comprises at least two portions which are axially movable to one another, the holder being provided with a mounting plate for the shaving unit, which holder and mounting plate are movable relative to each other in axially inward and outward directions. The external shaving member is secured to the mounting plate by means of at least one resilient element, so that the external shaving member with the mounting plate is also movable relative to the holder in both axial directions.

There is provided a shaving apparatus comprising a shear plate with hair-entry apertures; and a cutting unit associated with and reciprocatory relative to the shear plate, the cutting unit including a frame. Cutters extend from the frame toward the shear plate, each cutter having a trapezoidal cross section and being in contact along its base with the shear plate. Two hair-pulling blades are respectively associated with and movable relative to the opposite sloping sides of each cutter, each hair-pulling blade normally being in contact with the shear plate. A pair of resilient elements respectively connects the opposite ends of each hair-pulling blade to the frame.

An apparatus with a synchronous motor which is provided with a diametrically magnetized permanent-magnet rotor. The apparatus comprises a starting device for the motor which consists of a cam disc which is mounted on the shaft of the rotor of the motor and one or more spring-loaded pressure members which co-operate therewith during starting and which are movable transverse to the centre line of the rotor shaft.

Synchronous motor starting means

An electric hair trimmer for use as a home appliance having cutters covered by a flap which in the closed condition resiliently presses against a movable trimming cutter, and in the open condition allows removal of the cutters for cleaning.
