Definitions
- the invention relates to a shaving apparatus having a housing, provided with a holder in which at least one cutting unit is mounted, which cutting unit comprises an external cutting member and an internal cutting member which is rotatably drivable relative to said external cutting member, and provided with a skin supporting rim surrounding the external cutting member, which external cutting member has at least one hair-entry aperture and is mounted so as to be movable relative to the holder, said internal cutting member being in resilient engagement with the external cutting member.
- Such a shaving apparatus is known from US- A-4, 168,570.
- the skin supporting rim is formed by the edge of the opening of the holder in which the cutting units are mounted.
- the skin supporting rim serves for slightly tautening the skin before the external cutting member is moved over the skin.
- An even more important function of the skin supporting rim is to support the skin around the external cutting member. This ensures that the pressure on the external cutting member does not become too high. An excessive pressure leads to skin injury and irritation because the skin then penetrates further into the hair-entry apertures and can come into contact with the internal cutting member.
- the external cutting member is mounted in the holder so as to allow movement in, preferably, any direction.
- the shaving surface which is formed by the outer surface of the external cutting member facing the skin, can readily adapt itself to the shape of the facial area to be shaved.
- the maximum permissible tilting angle of the external cutting member is determined by the length over which the external cutting member projects above the skin supporting rim. A large projection length gives rise to large pressure peaks on the peripheral parts of the external cutting member because the skin supporting rim cannot properly support the skin. As already stated above, a higher pressure leads to skin injury and irritation.
- the invention is characterised in that the skin supporting rim is pivotable both relative to its associated external cutting member and relative to the holder. This precludes pressure peaks on the external cutting member.
- the external cutting member can tilt through a larger angle than in the prior-art shaving apparatus. As a result, the shaving apparatus is better conformable to the shape of the face. Since the external cutting member is arranged to be movable in any direction and is consequently also depressible, whereas the associated skin supporting rim is only pivotable and not depressible, a limitation of the maximum pressure is obtained.
- the skin supporting rim also has a protective function.
- a first variant is characterised in that the skin supporting rim is pivotable about two axes which are perpendicular to one another.
- a second variant is characterised in that it comprises two circular cutting units whose skin supporting rims are pivotable about a common axis which extends parallel to a connecting line through the centres of the cutting units.
- a third variant is characterised in that it comprises two or more circular cutting units each having a skin supporting rim which is pivotable about an axis situated in a plane parallel to a shaving plane defined by outer surfaces of the external cutting members, which axis extends perpendicularly to a connecting line between the centre of each cutting unit and the centre of gravity of the combination of cutting units.
- a modification thereof is characterised in that the skin supporting rims are coupled to one another by means of a hinge construction.
- the hinge construction should have some freedom of movement in the direction of the centres of the cutting members.
- the hinge construction is a so-called tongue-and-groove construction or an elastic hinge.
- Fig. 1 is a perspective view showing a shaving apparatus with three cutting units, in which the invention is used,
- Figs. 2a-2b show a cutting unit with a skin supporting rim which, in accordance with the prior art, is immobile relative to the holder
- Fig. 3 shows a cutting unit with a skin supporting rim as shown in Fig. 2a but with a larger tilting angle of the external cutting member
- Figs. 4a-4b show a cutting unit with a skin supporting rim which, in accordance with the invention, is pivotable relative to the holder,
- Fig. 5 shows a cutting unit with an immobile skin supporting rim and the pressure distribution near peripheral parts of the cutting member during contact with the skin in accordance with the prior art
- Fig. 6 shows a cutting unit with a pivotable skin supporting rim and the pressure distribution near peripheral parts of the cutting member during contact with the skin in accordance with the invention
- Figs. 7a, b, c, d show a cutting unit with a skin supporting rim which is pivotable in any direction relative to the holder
- Figs. 8a, b, c, d show a cutting unit with a skin supporting rim which is pivotable relative to the holder about two mutually perpendicular axes
- Figs. 9a, b, c show a cutting unit with a skin supporting rim which is pivotable relative to the holder about one axis
- Figs. 10-13 show different configurations of shaving heads with two, three and four cutting units, respectively.
- Fig. 14 shows a tongue-and-groove type hinge construction between two skin supporting rims
- Fig. 15 is a perspective view of a skin supporting rim as shown in Fig.
- Fig. 16 is a perspective view showing an element comprising three skin supporting rims for a triple-head shaving apparatus, the skin supporting rims being coupled to one another by an elastic integral hinge.
- the rotary shaving apparatus shown in Fig. 1 has a housing 1 with a detachable holder 2.
- three cutting units 3 are mounted, which units each comprise an external cutting member 4 and an internal cutting member 5 (see Fig. 7a), the external cutting member being surrounded by a skin supporting rim 6.
- the external cutting member 4, which is generally circular, has a substantially flat shaving surface 7 and has a multitude of slit-shaped hair entry apertures 8.
- the internal cutting member 5 has a number of cutters 9 (see Fig. 7a) secured to a support 10.
- the support can be coupled to a coupling pin 11, which is rotatable by a motor, not shown.
- the coupling pin 11 is provided with a spring 12, which urges the internal cutting member 5 towards the external cutting member 4 so as to maintain proper contact between the cutting members during shaving.
- the external cutting member 4 can be supported relative to the holder 2 by resilient means, as described in US-A-4, 168,570. This makes the external cutting member 4 resilient in a direction perpendicular to the shaving surface 7 in such a manner that the external cutting member can also be tilted slightly relative to the holder. Thus, the external cutting member is movable in any direction relative to the holder.
- the skin supporting rim 6 is a rim which is fixedly connected to the holder 2. In Figs.
- each skin supporting rim 6 takes the form of a separate part, which is pivotable relative to both its associated external cutting member 4 and the holder 2.
- the external cutting member 4 is arranged to be movable in any direction relative to the holder 2, so that the shaving surface 7 can readily adapt itself to the shape of the facial area to be shaved.
- the line 13 represents a curved portion of a facial area to be shaved.
- the external cutting members 4 will be tilted through an angle ⁇ l, so that the shaving surface is in better contact with the curved portions of the face.
- the facial areas which are situated nearer the ends of the curved line 13 are not in contact with the shaving surface 7.
- Figs. 4a-4b illustrate the situation in accordance with the invention.
- the associated skin supporting rims 6 are also tilted. This does not only result in a large tilting angle ⁇ 2 of the cutting member but it also ensures that an effective support of the skin by the skin supporting rim is maintained.
- the pressure (P2) on the peripheral parts of the cutting member is substantially lower. See also Fig. 6. This provides a better control of the pressure on the external cutting member.
- Figs. 7a-7d show a cutting unit in which the skin supporting rim 6 with the cutting members is pivotable in any direction in the holder 2.
- the inner edge 15 of the opening 16 in the holder 2 holding the cutting unit has a concave shape and an outer edge 17 of the skin supporting rim 6 has a corresponding convex shape.
- the tilting point bears the reference K.
- Figs. 7a-7b show the cutting unit in a non-tilted centre position.
- Fig. 7c shows the cutting unit (with the skin supporting rim) tilted in one direction and in Fig. 7d tilted in a direction perpendicular thereto.
- Figs. 8a-8d show a cutting unit in which the skin supporting rim with the cutting members is pivotable about two axes perpendicular to one another.
- the skin supporting rim 6 has bearing projections 18.
- the skin supporting rim has an arcuate pin 19 which engages an arcuate opening 20 in the projection.
- the cutting unit can be tilted about an axis Al.
- Fig. 8d shows this tilt relative to Fig. 8b.
- the tilt about an axis A2 which is perpendicular to the axis Al, is obtained in that the projection 18 is slidable in a cylindrical recess 21 in the inner edge 15 of the holder 2.
- Fig. 8c shows this tilt relative to Fig. 8a.
- Figs. 9a-9c show a cutting unit in which the skin supporting rim 6 is pivotable about one axis A.
- the skin supporting rim has two diametrally opposed projections 22, which engage in openings 23 in the holder 2.
- the tilting range can be limited.
- Fig. 9c shows the tilt relative to Fig. 9b.
- These projections 22 are also shown in Figs. 15 and 16. It is obvious that the tilting range can also be limited in another manner.
- Figs. 10-13 show different configurations of shaving heads with two, three or four cutting units. Each skin supporting rim with its associated cutting members is pivotable about an axis through the centre of the cutting unit.
- the tilting axes are disposed in a plane parallel to the shaving surface 7 (see also Fig. 14).
- the tilting axes are parallel to the connecting line 25 through the centres M of the cutting units and are also in line with one another.
- the tilting axes extend perpendicularly to a connecting line between the centre of each cutting unit and the centre Z of the combination of cutting units.
- each shaving head can be pivotable independently of one another. However, they can also be coupled to one another by means of 6 a hinge construction.
- Fig. 14 shows a construction in which the skin supporting rims are coupled by means of a so-called tongue-and-groove coupling.
- the skin supporting rims adjoin one another pairwise along portions which define a straight line 27 (see Fig. 12). Of these straight portions of each skin supporting rim one portion has a tongue 28 and the other portion has a groove 29.
- Fig. 15 is a perspective view showing such a skin supporting rim.
- Fig. 16 shows a construction for a triple-head shaving apparatus, where the three skin supporting rims are coupled to one another by means of an elastic integral hinge 30.
