Abstract: A shaving unit for a dry shaver includes at least one outer cutter and one under cutter. Driven by a motor, the outer cutter and the under cutter are movable relative to each other in an oscillatory motion. The under cutter and the outer cutter, which are biased into relative engagement by at least one spring, slide along a common contact surface. The spring is arranged in such a way that its biasing force always acts at an angle to the direction of oscillation.

Abstract: A shaving head for an electric dry shaver includes a base element for carrying at least three cutter units. Each unit provides an outer cutter and an inner cutter arranged to be moved in sliding contact relative to each other. At least one cutter unit includes a foil-type outer cutter. The shaving head further includes a first trimmer-type cutting unit that has a plurality of slots defined by a plurality of adjacent bar elements featuring cutting edges. The shaving head also includes a second trimmer-type cutting unit having an outer cutter that includes a plurality of teeth featuring cutting edges and spaced apart from each other so as to define a plurality of slits.

Abstract: A cutting head for an electric razor is provided. The cutting head has at least one upper blade and a lower blade associated with the upper blade, which upper and lower blades are movably supported relative to one another and can be driven accordingly by a drive device. The upper blade has a contact surface for the skin to be shaved, which contact surface is formed by a plurality of webs that are each bounded by slots. The longitudinal extent of the webs runs substantially perpendicular to a threading edge bounding the contact surface. The contact surface is designed to be concave and rises towards the threading edge, where the threading edge has an outer radius and this outer radius encloses an angle of less than 90°.

The primary electrical device includes an additional connector configured to couple the primary electrical device for receiving electrical or electromagnetic energy, such as from an electric mains voltage.

Abstract: The invention relates to a lower cutter (4) which, together with an associated upper cutter (6), forms the shaving head of a dry shaver. The upper cutter is designed in the form of a perforated foil (6) which at least partially encloses the lower cutter (4) and is prestressed against the same. The lower cutter (4) has a plurality of spaced-apart blades having cutting edges (12, 13) in the form of strips between two peripheral regions (9, 10). The lower cutter (4) is essentially U-shaped in cross section. The width of the strip tapers monotonously from the two peripheral regions (9, 10) in the direction of the center (Z).

Abstract: A shaving unit for an electric shaver which comprises an outer cutter and an inner cutter associated to that outer cutter. The cutters are mounted so as to be movable relative to each other and adapted to be set in a relative motion by a drive mechanism. The inner cutter provides a plurality of cutting edges and abuts with its outer face on the inner face of the outer cutter. The outer cutter provides a plurality of teeth equipped with cutting edges. The outer cutter provides two comb elements which are disposed opposite one another and which extend according to the direction of the relative motion. The two comb elements are aligned with respect to one another such that the tips of the teeth of the first comb element are facing the tips of the teeth of the second comb element, the tips of the teeth spaced from one another.

Abstract: The present invention is directed to an electric shaver having a shaver housing, and a shaving head housing that is connected to the shaver housing for pivotal movement between two end positions. The shaving head housing carries at least two shaving assemblies, of which at least one shaving assembly is retractable into the housing to a first, retracted position, and elastically biased toward a second, extended position, such that extension of the at least one shaving assembly is a function of contact pressure applied by a user. Actuating elements carried by the shaving head housing control a maximum degree of extension of the at least one shaving assembly as a function of a pivot angle between the shaver housing and the shaving head housing.

Abstract: An electric shaver has a pivotally mounted longhair cutter unit that is pivoted outward into an operating position by motion of an operating switch of the shaver via an actuator that also causes the cutting blades of the longhair cutter unit to extend from the longhair cutter housing. Because the longhair cutter retracts into the longhair cutter housing when the longhair cutter unit is folded shut, the sharp edges of the blades are protected.

Abstract: An electric-powered shaving apparatus with a drive part excitable by an electric motor into performing an oscillatory motion, the drive part transmitting its motion for cutting hairs to a short-hair cutter and to a long-hair trimmer. The long-hair trimmer is displaceable relative to the housing into an advanced and a retracted position. The motion of the drive part for the short-hair cutter is utilized for moving the long-hair trimmer into the advanced position.

Abstract: A cleaning device for the shaving head of a dry shaving apparatus includes a receptacle formed in a housing of the cleaning device. The receptacle adapted to receive the shaving head for cleaning with a cleaning fluid. During the cleaning cycle, the dry shaving apparatus is lockable in the cleaning device by means of an interlock. The shaving head is exposed to heat from a heater for drying subsequent to cleaning. Following a drying cycle, release of the interlock is controlled by a control element provided in the cleaning device to prevent an operator's skin from being burned by an excessively hot shaving head in an immediately succeeding shaving operation.

The first outer cutter is coupled to the drive source and is mounted for oscillatory movement to serve as a skin agitation member. The first outer cutter and the second undercutter are arranged to be driven at the same frequency by the drive source.
