Abstract: A shaving apparatus having at least one cutting unit with an external cutting member and a rotatable internal cutting member each the external and internal cutting members having cooperating cutting edges forming bearing surfaces of a first bearing, and a second bearing with bearing surfaces. To minimize the friction between the cutting edges, a support device having visco-elastic properties is provided between the two bearings. During operation, the distance between the bearing surfaces of the first bearing adjusts to the distance between the bearing surfaces of the second bearing. During cutting of hairs, the support device behaves as a stiff element whereas during periods in which no hairs are cut, the support device behaves relatively soft so that the cutting gaps between the cutting edges are closed.

Abstract: Shaving apparatus having at least one cutting unit with an external cutting member and a movable internal cutting member. An energy-dissipating system is provided between mutually movable parts of the internal or an external cutting member to reduce the bouncing effect between the internal and external cutting member after cutting a hair. Such an energy-dissipating system may for example be an element with visco-elastic properties.

Abstract: A shaving apparatus includes at least one cutting unit having an inner cutter rotationally drivable with respect to an outer cutter by driving shaft of a driving device. The driving shaft exerts a prestress force on the inner cutter in the direction of the outer cutter. During cutting of a hair, the hair exerts a cutting force on the inner cutter directed opposite the driving force. The driving shaft bears axially on the outer cutter via at least one driving surface of a coupling element which is rotationally drivable. The inner cutter includes at least one driven surface for cooperating with the driving surface for exerting the driving force. The direction of the driving force is substantially perpendicular to the driving surface and the driven surface.

Abstract: Shaving apparatus having at least one cutting unit (3) with an external cutting member (4) and a rotatable internal cutting member (6) each having cooperating cutting edges (8,9) forming bearing surfaces of a first bearing, said external and internal cutting member (4,6) having a second bearing with bearing surfaces (14,17). To minimize the friction between the cutting edges (8,9), means (13) with visco-elastic properties are provided between the two bearings, so that during operation the distance between the bearing surfaces (8,9) of the first bearing adjusts oneself to the distance between the bearing surfaces (14,17) of the second bearing. During cutting of hairs the means with visco-elastic properties behave as a stiff element whereas during periods in which no hairs are cut these means behave relatively soft so that the cutting gaps between the cutting edges are closed.

Abstract: Shaving apparatus having at least one cutting unit (3) with an external cutting member (4) and a movable internal cutting member (6). To reduce the bouncing effect between the internal and external cutting member after cutting a hair, an energy-dissipating system (22) is provided between mutually movable parts of the internal (6) or external cutting member (4). Such an energy-dissipating system can for example be an element (22) with visco-elastic properties.

Abstract: Shaving apparatus with at least one cutting unit (3) having an outer cutter (4) and an inner cutter (6) which is rotationally drivable with respect to the outer cutter by means of an driving shaft (18) of a driving device, which driving shaft exerts a prestress force (FY) on the inner cutter in the direction of the outer cutter. During cutting of a hair, the hair exerts a cutting force (FR) on the inner cutter (6), which force has a direction that is opposite to the driving force (FD) for driving the inner cutter.

Abstract: A shaving apparatus has a housing (1), a shaving head (2) and a hair-collecting chamber (3) for collecting hair cuttings, the shaving head comprising a holder (4) which is connected to the housing by means of a hinge construction (15). The holder comprises an external cutting member (6) and an internal cutting member (8). For driving the internal cutting member a drive member (11) of a drive unit (10) can be coupled to the internal cutting member (8). For cleaning the hair-collecting chamber (3) the chamber is opened by pivoting the holder (4) and after the cleaning process the holder is pivoted back onto the housing. During opening and closing of the hair-collecting chamber the drive member (11) and the internal cutting member (8) are coupled and uncoupled. In order to improve coupling and uncoupling the hinge construction is such that in a first stage of the movement of the holder the holder is moved substantially in a longitudinal direction (14) of the drive member (11).

Abstract: An electric shaving apparatus comprising a housing having a compartment for an electric power source, which compartment is closed by a cover, the housing sections being secured to each other by a snapped connection between two interengaging connection elements, at least one of the connection elements being elastically deflexible to establish or release the snapped connection. The cover comprises a projection which in the closed position of the cover blocks a movement of at least one of the connection elements.

Abstract: A shaving apparatus is provided which comprises a holder for at least one shaving unit, which shaving unit comprises an external shaving member formed with hair-entry apertures and an internal shaving member which is rotatable relative to the external shaving member, the shaving unit being arranged in an opening of the holder and being retained by means of a retaining plate which is detachably secured to the holder, the holder and the retaining plate comprising corresponding fixing means.

Abstract: A shaving apparatus comprises a housing; an external shaving member formed with hair-entry apertures and engaging the housing; and an internal shaving member associated with the external shaving member and rotatable relative thereto. A drive shaft couples the internal shaving member to a motor, the drive shaft having a hub. A pin engages the hub for rotatably supporting the drive shaft. Two separate radially acting cylindrical bearing surfaces of different diameters are provided on the pin. Two separate cylindrical radially acting bearing surfaces of correspondingly different diameters are provided on the hub for cooperation with the respective separate radially acting cylindrical bearing surfaces provided on the pin. A supporting plate is provided within the shaving apparatus housing, the pin and the supporting plate being formed as a one-piece plastic unit.

Abstract: An apparatus such as a dry shaver comprises a housing formed by two opposing housing sections accommodating an electric motor therewithin. A first outwardly extending mounting rim and a second outwardly extending mounting rim are provided on the electric motor, the second mounting rim being spaced from the first mounting rim. The first and second mounting rims engage the two housing sections and axially retain a part of each housing section therebetween. An axially directed edge portion is provided along the periphery of the first mounting rim and engages the two housing sections to radially retain the same therebetween.
