Abstract: A shaving apparatus having a head portion intended for contact with a skin surface to cut hairs growing therefrom. The head portion may include a cylindrical screen and a cutting component located within a cavity defined by the cylindrical screen. The cylindrical screen includes a plurality of openings so that a user's hairs can pass therethrough to be cut by blades of the cutting component. The cylindrical screen may be rotatable about a rotational axis so that as the cylindrical screen is placed into contact with a skin surface and moved therealong, the cylindrical screen is made to rotate about the rotational axis. The shaving apparatus may include a brake sub-system to intermittently reduce a rotational velocity of the cylindrical screen.

Abstract: There is provided a shaving apparatus having a head shaving portion that includes a rotary cutter and one or more roller elements configured to provide close skin contact with a fixed cutting blade, as well as to methods of using the same for efficient cutting of hair bristles off a skin region.

Abstract: A shaving apparatus (1000) includes a rotary cutter (220) comprising a cutter tube, the rotary cutter comprising a plurality of closed-geometry apertures (221) in an outer surface of the cutter tube, each of the closed-geometry apertures extending along an aperture axis and comprising: a cutting edge (222); a first section having a first width measured transverse to the aperture axis; a second section having a second width measured transverse to the aperture axis; a waist section having a third width measured transverse to the aperture axis, the waist section located between the first and second sections; and the third width being less than each of the first and second widths; a blade (211) having a cutting edge, the blade mounted adjacent the rotary cutter; and an electric motor (130) operably coupled to a power source and the rotary cutter to rotate the rotary cutter about a rotational axis of the rotary cutter so that a user's hairs are sheared between the cutting edge of the blade and the cutting edges of

Abstract: A motorized shaving apparatus and head therefor that cuts or trims hair via shearing. In one embodiment, the invention is a shaving apparatus head comprising: a body; a rotary cutter mounted to the body so as to be rotatable about a rotational axis, the rotary cutter comprising cutting edges that collectively define a reference cylinder about the rotational axis; and a blade mounted to the body so as to extend along a first reference plane that intersects the reference cylinder, the blade positioned so that a user's hairs are sheared between a cutting edge of the blade and the cutting edges of the rotary cutter when the rotary cutter is rotating about the rotational axis.

Abstract: A shaving apparatus in which a rotary cutter and a fixed blade are used to shear a user's hairs therebetween during a shaving process. Rotation of the rotary cutter is driven by an electric motor. In certain embodiments, the rotary cutter comprises a cutting tube that comprises a plurality of apertures that are defined by cutting edges which form a closed-geometry. In other embodiments, a lubricating element is coupled to the rotary cutter. In further embodiments, the apertures are arranged in a pattern to control the number and selection of apertures that are capable of being active to shear hairs at any one time. In even further embodiments, the fixed blade is integrally formed with the housing of the head; the housing is formed by a plurality of flat plate segments; the rotary cutter is formed by a plurality of stacked flat plate segments; and/or the fixed blade can reciprocate.

Abstract: A shaving apparatus (1000) in which a rotary cutter (300) and a fixed blade (350) are used to shear a user's hairs there between during a shaving process. Rotation of the rotary cutter is driven by an electric motor (400). In certain embodiments, the rotary cutter comprises a cutting tube (301) that comprises a plurality of apertures (305) that are defined by cutting edges (307) which form a closed-geometry. In other embodiments, a lubricating element (800) is coupled to the rotary cutter, in further embodiments, the apertures are arranged in a pattern to control the number and selection of apertures that are capable of being active to shear hairs at any one time. In even further embodiments, the fixed blade is integrally formed with the housing of the head; the housing is formed by a plurality of stacked flat plate segments: the rotary cutter is formed by a plurality of stacked flat plate segments; and/or the fixed blade can reciprocate.

Abstract: A motorized shaving apparatus head and motorized shaving apparatus incorporating the same. In one embodiment, the invention is a shaving apparatus comprising: an elongated handle having a longitudinal axis; a power source; a head coupled to a distal end of the elongated handle, the head having a working surface with a longitudinal width of 40-44 mm and a transverse width of 14-16 mm; the working surface comprising a fixed blade having a cutting edge; a rotary cutter having cutting edges disposed within the head, the cutting edges of the rotary cutter positioned adjacent the cutting edge of the fixed blade so that a user's hairs are sheared between the cutting edge of the fixed blade and the cutting edges of the rotary cutter when the rotary cutter is rotating; and a motor operably coupled to the rotary cutter to rotate the rotary cutter about an axis.
