Definitions
- the invention relates to a shaving apparatus comprising a drivable cutting unit with cutters, each cutter being equipped with a lead cutter, which leads in the direction of driving and which is movable relative to the cutter.
- Such a shaving apparatus is for example known from Netherlands Patent Application 7404 657 (PHN 7351).
- the lead cutters serve to slighly pull the hairs, so that a better shaving result can be obtained.
- the distance over which the hairs can be pulled is limited by the shape and dimensions of the cutter and the lead cutter and by the properties of the hairs and the skin.
- each cutter in addition to the said first lead cutter, is equipped with a second lead cutter which leads relative to the first lead cutter and which second lead cutter is movable relative to the first lead cutter.
- each cutter is provided with more than two lead cutters, each second and further lead cutter being movable relative to an adjacent preceding lead cutter.
- the invention is also embodied by a cutting unit as used in one of the embodiments described in the foregoing.
- the shaving apparatus in accordance with Figures 1 and 2 comprises a housing 1, of which a part takes the form of a shear plate holder 2 for three shear plates 3.
- the shear plates 3 are formed with hair-entry apertures 4.
- a cutting unit 5 is situated on the inner side of a shear plate 3.
- This cutting unit 5, which for the sake of clarity is only shown schematically in Fig. 2, comprises a cutting member with cutters and lead cutters, and is shown in perspective view and on an enlarged scale in Fig. 3.
- the cutting unit 5 is coupled to the electric motor 10, by means of the hollow spindle 6 (Fig. 2), the gear wheels 7 and 8 and the spindle 9, so that the cutting unit is rotatable relative to the associated shear plate 3.
- the gear wheel 7 is rotatably journalled on a pin 11, which is mounted in a mounting plate 12.
- the gear wheel 7 is formed with a recess 13, which is closed by a cover plate 14. This recess accommodates the flange 15 at the end of the hollow spindle 6.
- the spring 16 which for the greater part is disposed in the hollow spindle 6 and which is tensioned between the hollow spindle 6 and the gear wheel 7, exerts a force on the spindle 6 in the direction of the cutting unit 5.
- said force is exerted on the cutting unit and via the cutting unit on the shear plate 3, so that the shear plate is urged against the shear plate holder 2 with the rim 18.
- the shear plate 3 together with the cutting unit 5 and the spindle 6 can be pressed inwards against the action of the spring 16 as a result of exernal forces, as may for example occur during use of the shaving apparatus..
- the coupling for transmitting the rotary movement between the spindle 6 and the cutting unit 5 is obtained in that the spindle 6 is provided with an end 19 of substantially rectangular cross-section. This end 19 is situated in a corresponding coupling aperture 20 of the cutting unit 5.
- the cutting unit 5 ( Figure 3) comprises a cutting member 21 which is essentially constituted by a central member 22 which at its circumference is provided with cutters 23.
- the central body 22 has a coupling aperture 20.
- Each cutter 23 is provided with a first lead cutter 24 and a second lead cutter 25.
- the lead cutters 24 are combined to a lead cutter unit 26 which comprises a central portion 27 to which the lead cutters 24 are connected by means of the arms 28.
- the lead cutters 25 form part oa a lead cutter unit 29 with a central portion 30 and arms 31. Owing to the elastic properties of the arms 28 and 31 the lead cutters 24 and 25 are movable relative to the associated cutters 23.
- the central body 22 of the cutting member 21 and the central portinns 27 and 30 of the lead cutter units are connected to each other, for example by spotwelding.
- Figures 4, 5 and 6 schematically represent a side view of a part of the cutting unit 5 and a part of the shear plate 3 and serve to illustrate the operation of the lead cutters.
- the hair 32 will be taken along by the lead cutter 25 until the sharp edge 36 of the lead cutter 24 has reached the hair 34 at the location B (Fig. 5). Under the influence of a similar system of forces as illustrated in Fig. 4 the lead cutter 24 will slide along the guide wall 37 of the cutter 23. The hair is now taken along by the lead cutter 24 untal the cutting edge 38 of the cutter 23 has reached the hair at the location C (Fig. 6). Subsequently, the hair 32 will be cut off by cooperation of the shear plate 3 and the cutter 23.
- the length AB over which a hair can be pulled by a lead cutter is inter alia limited by the dimensions of the lead cutter, in particular the thickness D (Fig.
- the distance AC over which a hair can be pulled can also be achieved with a single lead cutter having a thickness 2D.
- the bending moment relative to the shear plate which is exerted on the hair 32 by the lead cutter then has a maximum arm AC and is therefore theoretically twice the bending moment exerted on the hair 32 in the case of two lead cutters 24 and 25 in accordance with Figures 4 to 6, the maximum arm being only AB or BC.
- This bending moment as a result of which the hair tends to be pressed against the inner side of the shear plate 3 is one of the main limiting factors in respect of the length over which the hair can be moved. By the use of two or more lead cutters this length may therefore be increased proportionally.
