Definitions
- the invention relates to a shaving apparatus comprising an external cutting member having a shaving portion formed with hair-entry apertures and an internal cutting member which is rotatable relative to the external cutting member and which comprises cutting elements which extend in an axial direction towards said shaving portion.
- Such a shaving apparatus is known from NL-A-72 17 486.
- this apparatus the free ends of the cutting elements are in contact with the inner side of the shaving portion of the external cutting member. During use of the apparatus this will produce annoying noise and wear will occur at the areas of contact, whilst the external cutting member may become uncomfortably hot due to friction.
- the known construction is such that the clearance between the two cutting members may vary as a result of forces obtaining during shaving, so that the clearance between the cutting members may become too large for an effective shaving action.
- the invention is characterized in that the internal and external cutting members are provided with interacting bearing surfaces for rotationally supporting the two cutting members relative to each other in the axial direction, said bearing surfaces immediately adjoining the cutting elements and the shaving portion of the respective cutting members and forming integral parts of said cutting members.
- the shaving apparatus shown in Figures 1 and 2 comprises a housing 1, of which a part is formed as a holder 2 for three external cutting members 3.
- the cutting members 3 are formed with slit-like hair entry apertures 4, which are represented by a single line in Fig. 1 and which are located in an annular shaving portion 5 of each cutting member.
- each internal cutting member 6 is arranged at the inner side of each external cutting member 3.
- Each internal cutting member 6 mainly comprises a plate-shaped body 7 and cutting elements 8 which extend in an axial direction towards the shaving portion 5 of the associated external cutting member.
- each internal cutting member 6 is coupled to the electric motor 13, to be rotated thereby relative to the associated external cutting member 3.
- the gear-wheel 10 is journalled on a pin 14 mounted in a mounting plate 15.
- the gear-wheel 10 formed with a recess 16 which is closed by a cover 17.
- the recess 16 engages with a flange 18 at the end of the hollow spindle 9.
- a cylindrical portion 20 of the spindle 9 bears against the cutting member 6 to transmit said force to this cutting member and via this cutting member to the associated external cutting member 3, so that a flange 21 on the rim of the external cutting member 3 is urged against the holder 2.
- the cutting members 3 and 6, together with the spindle 9, can be pressed inwards against the action of the spring 19 by external forces such as those which may occur during use of the shaving apparatus.
- a coupling for transmitting the rotary movement of the spindle 9 to the internal cutting member 6 is formed by an end portion 22 of the spindle of rectangular cross-section engaging in a corresponding rectangular coupling aperture 23 in the cutting member 6.
- a peripheral portion of the plate-shaped body 7 of each internal cutting member 6 forms a flange 24 which is in contact with a flange 25 on the rim of the associated external cutting member 3.
- the respective contact surfaces 26 and 27 of the flanges 24 and 25 constitute a plain bearing by means of which the two cutting members 3 and 6 are journalled relative to each other.
- the clearance 28 between the face ends of the cutting elements 8 and the shaving portion 5 can now be optimized for an effective shaving action.
- the cutting elements 8 and the shaving portion 5 do not touch each other, so that these parts are not subject to wear and no noise and heat are produced at the location of the shaving portion as a result of friction.
- the sliding contact between the contact surfaces 26 and 27 of the flanges, 24 and 25 can be optimized, so that a substantial improvement of the bearing arrangement is obtained in comparison with that attainable between the ends of the cutting elements 8 and the shaving portion 5 with the hair-entry apertures 4, with the result that less power is required for driving the internal cutting members 6.
- the internal cutting member 6 comprises a hollow cylindrical, central boss 29 whose flat end surface 30 constitutes a plain bearing with the surface 31 of the central recessed portion 32 of the external cutting member 3.
- the cutting members can be centred relative to each other by providing a slight clearance between the ring of cutting elements 8 and the recessed portion 32.
