Definitions
- the invention relates to a hair clipper of the type corresponding to the preamble of claim 1.
- Such a hair clipper is known as a shaving and hair clipper from DE-PS 392 773.
- a normal double-sided razor blade is used, which can be fastened to the cutter head by means of a releasable clamping device, as is known from the well-known manual shaving apparatus.
- This clamping device comprises a slightly curved plate covering the razor blade except for the cutting edges, which can be tightened against a correspondingly arched base by means of a screw which, in the middle, penetrates a perforation of the razor blade and thereby clamps the razor blade located therebetween.
- the clamping device is complex to manufacture and, owing to the essentially linear arrangement, cannot ensure that the razor blade is clamped free of vibration in the vicinity of the cutting edge.
- the invention has for its object to improve a generic hair clipper.
- DE-PS 392 773 has a single blade with two cutting edges pointing towards opposite sides.
- the two rollers are located near the cutting edges on the same side of the blade. When changing the cutting edge while rotating the device by 180, the roller comes to lie on the other side, as seen by the operator, which makes operating the device difficult or even impossible in practice.
- the blade can be arranged opposite the roller according to claim 5.
- This design of the circumferential surface of the circumferential webs results in a type of edge being formed on the two flanks of the circumferential webs, which prevents the strand of hair resting on this circumferential web from sliding sideways into one of the adjacent circumferential grooves.
- the hair strands lying on the outside and entering the inside of the circumferential grooves and preferably exposed to the cutting action are effectively separated in this way.
- the rollers have thread-like circumferential grooves, the purpose of which is to move the hair a little in the axial direction when the rollers rotate, in order to achieve a pulling cut.
- the circumferential webs are so narrow here that the hair cannot be held on the outer circumference thereof and the entirety of the hair of a strand is found on the base of the circumferential grooves.
- the cutting edge is on one Assigned to the axis are individual rollers which are intended to prevent the cutting edge of the razor from penetrating into the skin during shaving and which, when rotated, are intended to remove the soap foam and the cut hair.
- the rollers have circumferential webs in a cut through the axis. rounded outer circumference that the strands of hair cannot hold.
- the depressions in the circumferential surface of the circumferential webs can be designed in detail in the ways specified in claims 8 to 10, the selection of which takes place depending on the desired thinning effect.
- rollers can be designed in the manner set out in claim 11.
- the circumferential webs are designed here only as relatively thin disks which have the sole purpose of keeping the fingers away and preventing cut injuries on the cutting edge.
- the embodiment according to claim 12 results in a roll for a pronounced effect cut, in which the strand is displaced along the cutting edge during movement through the helically wound peripheral web.
- FIG. 1 and 2 are views of a first and a second embodiment of a hair clipper
- Fig. 3 is a view of FIG 1 from above, in the right half in section along the line III-III in Fig. 1.
- FIG. 4 is a view of a third embodiment of the hair clipper
- 5 to 7 are partial sections through the axis of a roller, through the edge region thereof with different designs of the peripheral surfaces of the peripheral webs;
- FIG. 8 is a view of a fourth embodiment of a hair clipper;
- FIG. 9 shows a partial longitudinal section through the roller axis of area IX in FIG. 8;
- FIG. 10 is a view of a fifth embodiment of a hair clipper
- Fig. 11 is a section along the line XI-XI in Fig. 10,
- a knife head 2 extends upwards, which is essentially plate-shaped and has a front flat side 3 and one has rear flat side 4 (Fig. 3).
- rollers 8, 9 are freely rotatably mounted, for the accommodation of the knife head 2 laterally Has recesses 11, 12, which are as long as the rollers 8.9.
- the recesses 11, 12 form niches in which the rollers 8, 9 find space.
- the ends 6 ', 6 "of the axis 6 engage parts 33, 34 of the cutter head 2 which overlap the end faces of the roller 8.
- the roller 8 is a smooth cylindrical roller.
- the roller 9 has circumferential grooves 26 distributed over its length at regular intervals.
- a strand is passed by hand over the roller 8 and by slightly turning the handle 1 the cutting edge 19 of the upper blade in FIG. 3 and the rear blade 18 in FIG. 1 is attacked.
- the result is a smooth cut, it being possible to determine by turning the handle 1 accordingly whether a cut should be made immediately into the strand or a cut that is gradually becoming deeper.
- the hair clipper 10 is rotated by 180 so that the roller 9 takes the place of the roller 8.
- a strand passed over the roller 9 partially enters the circumferential grooves 26, and only these hair strands are gripped by the cutting edge 19.
- the boundaries 31 of the recess 11 and 32 of the recess 12 run obliquely towards the operating side of the hair clipper 10 from the respective roller 8 or 9, so that the operator from the operating side through the respective recess 11 or 12 one Elick on the cutting edges 19 and the working of the device.
- the embodiment 20 of FIG. 2 corresponds to that according to FIG. 1 with the exception of the rollers 38, 39, which in the exemplary embodiment are designed as counter-rotating screws with particularly deep threads, the cross-section of which is approximately the shape of a plane passing through the roller axis has slightly inclined "V". If one of the rollers 38, 39 is guided along a strand of hair when working with the hair cutting device 20, the rotation of the rollers 38, 39 results in a shift of the hair strands entering the individual thread turns in the axial direction of the rollers 38, 39 and thereby pulling effect cut.
- a removable protective cap 37 is indicated in FIG. 2, which can consist of a transparent plastic and is placed over the cutter head 2 when the hair clipper is not in use.
- partially spherical elevations 35 or transverse ribs 36 are provided on the handle 1 below the cutter head 2.
- both rollers 9, 9 ' have circumferential grooves 26, 28 distributed over their length at regular intervals, which are separated from one another by circumferential webs 48, 49.
- the circumferential grooves 28 and circumferential webs 48 are somewhat narrower and seven circumferential grooves 28, which are identical to one another, are distributed over the length of the roller 9' which is approximately 50 mm.
- the right-hand roller 9 in FIG. 1 only five circumferential grooves 26 are present.
- the circumferential grooves 26, 28 and the associated circumferential webs 48 and 49 are of equal width to one another, the circumferential grooves 26 are approximately as deep as they are wide, measured from the outermost circumference of the roll in question.
- the strand of hair is separated into fewer, somewhat wider hair strands than with the roller 9 ', from which the hair strands lying on the base 26' of the circumferential grooves 26 are cut.
- cross-sectional shapes of the circumferential webs 49 of the roller 9 are shown on an enlarged scale. The same cross-sectional shapes can also be used for the finely divided roller 9 '.
- the circumferential webs 49 are recessed on their outer circumferential surface.
- the outer circumferential surface 53 is concave with a circular cross section, the center of the circle 54 being located symmetrically to the circumferential web 49 "and the radius 55 corresponding approximately to the width of the circumferential web 49 '.
- the depression is formed by a cylindrical part 56 of the circumferential surface which is coaxial with the axis of the roller 9 and which rises outwards to the outermost circumference via inclined surfaces 57.
- the depression is formed by V-shaped inclined surfaces 58, which in the exemplary embodiment form an angle of approximately 120 with one another.
- an edge elevation is formed on the flanks 51 of the circumferential web 49 ′ or 49 ′′ or 49 ′′, which means that a strand of hair lying thereon is prevented from slipping into the adjacent circumferential grooves 26 and towards the center of the depression is pushed.
- the circumferential grooves 26 have a rectangular cross-section, ie their cylindrical base extends coaxially to the axis of the roller 9, so that the hair lying on the base is simultaneously gripped by the cutting edge 19.
- the flanks 51 of the circumferential webs 49 there is a clearly pronounced step in the height of the hair. The same applies to the roller 9 'and its circumferential grooves 28.
- the handle 1 is kept slimmer than in the embodiments of FIGS. 1, 2 and 4 and is provided with a widening provided for ergonomic reasons approximately in the middle of its length. This embodiment facilitates turning the hair clipper 40 in the hand.
- the overall structure of the hair clipper 40 differs from the embodiments 10, 20 and 30 only by the type of rollers 59, 59 '.
- the roller 59 comprises a cylindrical core 61 which is freely rotatable on the axis 6 and about which two narrow strips 62 are wound helically as a circumferential web.
- the strips have a flat rectangular cross-section and the longer side of the cross-sectional rectangle extends perpendicularly outwards from the axis 6.
- the screw formed is two-course in the embodiment, i.e. two strips 62 are wrapped together.
- the roller 59 forms a left-handed screw, the roller 59 'a right-handed screw. A change allows effet cuts of different orientations.
- the left roller 9 corresponds to the rollers 9 of FIGS. 1 and 4.
- the right roller 69 in the exemplary embodiment has five uniformly distributed on a cylindrical core 63 only over the length of the roller 69, relatively thin radially projecting disc, the relative between them leave wide circumferential grooves 66.
- the total amount of hair strands sits on the bottom of the circumferential grooves 66 and is cut straight on the cutting edge 19.
- the discs 64 have the purpose of largely preventing the strand of hair from slipping in the longitudinal direction of the roller 69 and, moreover, of keeping the fingers away from the cutting edge 19.
- FIG. 11 shows that, in contrast to FIG. 3, the blade plane 44 no longer points radially outside the rollers, but extends within the outer circumference of the rollers 9 or 69, but outside the respective core 61 or 63 of the roll.
- the groove-like recesses 13 ', 14 * are formed in the hair clipper 50 as slots which enclose the brackets 15 on both sides from the outside.
- the holders 15 therefore only need to be pushed in lengthwise, but do not have to be glued or fastened in any other way,
