With reference to Figures 1 to 5 there is shown an embodiment of the device comprising an inner 30 and an outer barrel 20, capable of rotating freely each providing a plurality of blades 32, which during rotation act against each other to provide a scissor action, which scissor action is arranged to cut, for example hair.
The device comprises a bipartite housing 15, with a largely triangular side profile, with two long sides 10,11 and a short side 12, curved corners 13,14,19 and having two large faces 8. In some embodiments one or more of these faces may be opened to remove cut hair.
The barrels are substantially inside the housing, projecting through a slot 32 to allow the outer barrel to contact the user’s face.
The inner barrel is connected to end caps 33 which end caps are driven by a gear arrangement comprising three gears wheels 16,17,18, which gearwheels are arranged such that a small gear wheel 17 meshes with a first large gear wheel 18 which rotates the inner barrel, being connected via axle ends 632.
Medium gear wheels 16 are joined by an axle 640 to form a gear 64, and driven by the large gear wheels 18, joined by an axle 600 to form a gear 60
The medium gear 64 further drives the outer barrel 20, which has outside gearwheels 69.
The barrels therefore counter-rotates in response to rotation on the outer barrel, or large gear, wherein the large gear protrudes through apertures 151 at a corner 14 of the housing. The large gear and/or outer barrel may be driven manually against the face or by the user’s hand, depending on area shaved.
The barrels rotate within a housing, the housing comprising two housing sections with a substantially isosceles triangle side section, wherein the outer barrel is arranged at a first corner of the short side, and a drive gear at the second corner of the short side.
The inner barrel has a series of runners 31 between the end discs 33, which runners run parallel the axis, and support blades 32, facing circumferentially in either direction, and overhanging the edge of the runners. The blades are inset into slots 34 in the discs 33.
The blades may have cutting edges arranged to incline inwards off-circumference.
The outer barrel comprises four transverse openings provided by five bars 21 and three data 23 parallel the barrels rotation axis. The slots and data are formed as a unitary part, having an enlarged diameter so as to extend outside of the housing, providing shoulders 24. One end 25 of the outer barrel is displaceable for manufacture and/or blade maintenance.
With reference to the diagrammatic embodiment shown in Figures 6 the arrangement of gearing is shown in Figure 6a, wherein the larger gear wheel is shown as 18B, the medium or drive gear wheel as 16B, the inner barrel as 30B and the outer barrel as 20B. The barrels are arranged to mesh with the gear wheels, and the whole is comprised in and extending from a housing 15B.
The housing provides seats 66 for the axle of the large gear 60, 68 and 152 for the axle of the barrels, and 67 for the drive or medium gear 64. The seat 66 of the larger gear 60 is elevated one a pillar 65 from one part of the housing and the drive gear another column 153 against the side wall of the other part of the housing.
With reference to the barrel embodiments shown in Figure 7 to 10 the barrels comprise two tubes, being inner barrels 30A and 30C, and outer barrels 20A and 20C, the inner barrels and outer barrels arranged in use coaxially, wherein the outer diameter of the inner barrel is substantially equal to the inner diameter of the outer barrel, such that the barrels provide a close tolerance between them.
In Figures 7 the inner barrel 30A further includes apertures through the tube walls between runners 31C, which thereby provide the blades 32C.
In Figures 8 the outer barrel 20A comprises apertures through the tube walls between runners 23A, which thereby provide the blades 32A and which are separated by transverse bars 21A to guide hair.
In Figures 9 the outer barrel 20C comprises apertures through the tube walls between runners 23A, which thereby provide the blades 32A.
In Figures 10 the inner barrel 30C further includes apertures through the tube walls between runners 31C, which thereby provide the blades 32C
The apertures are cut using laser tube cutting process at an acute angle off the radius on the inner barrel, and an obtuse angle off the radius on the outer barrel, so as to provide opposing inclines to the blades.
The barrels may comprise stainless steel, or other metal or alloy, arranged such that the blades may be sharpened or sharp.
The blades in the pictured embodiment run parallel the barrel axis blades. In some other embodiments the blades may be helical slanted or crossed.
Figure 11 shows a detail view of barrels similar to those shown in Figures 7 to 10, assembled in diagrammatic format.
Figure 12 shows a third embodiment, wherein a drive gear 64D drives gear wheels 16D, large gear wheel 18D, inner barrel gear wheel 17D and outer barrel gear wheel 333D. The inner barrel 30D and outer barrel 20D are consequently rotated, through connection with end caps 33D and 333D respectively.
An axle 300 connects the inner gear wheels 17D, and the outer barrel end cap 333D meshes with the drive wheel 16D.
The drive gear 64D may be driven manually, for example through a spring or band mechanism and/or digit roller and/or electrically through a drive belt.
With reference to figures 13 to 15 there is shown an embodiment of the hair cutting device 1 comprising a barrel comprised of a rotatable barrel 5 of blades, and a counterrotating guide member 2 providing a sequence of data for the blades.
The guide is arranged to rotate against the user, wherein in use the guide may be placed against the user’s skin, face or hair and the guide and rotated automatically or through friction on the user.
In this fourth embodiment the guide comprises a toothed larger first gear 41, or guide gear wheel, which gear turns a smaller second gear 76, or barrel gear wheel, wherein the second gear is attached to the barrel or the barrel axle 75 so as to drive rotation as teeth on the gears mesh.
In the fourth embodiment the barrel is a cylindrical form, with the second gears on distal ends, and including a plurality of spaced blades 73, arranged longitudinally between ends 71, such ends having regularly spaced slots 72 and projections 74 for receipt of the blades. The axle of the barrel extends beyond the ends to provide distal rotation points.
In the fourth embodiment the second gears are smaller than the first gears, such that the barrel rotates faster than the guide.
In the fourth embodiment the guide comprises a central axis 42, which axis runs between the larger first gear wheels 41 and provides perimetric rotating points 44.
The guide central axis in the pictured embodiment comprises a plurality of spokes 43, which spokes extend in a plurality of directions and are spaced along the guide axis. The spokes extend radially. In the pictured embodiment the spokes rotate with the guide wheels, in counter-rotation to the barrel.
In this way the guide or guide wheels may be run against the user’s face, for example down the user’s chin, and the barrel and the blades rotate in a counterwise direction to the guide wheels, central axis and spokes, so as to cut hair on the chin, and so that the spokes urge hair towards the blades.
In the fourth embodiment the device further comprises a guard 5, which guard is a section of a housing, wherein the guard surrounds the barrel in three longitudinal directions, and the housing extends from the guard to surround the barrel ends and providing a handle 4 in the fourth direction.
In the fourth embodiment the housing thereby comprises a head part 6 and a handle part 4. In the pictured embodiment the head part comprises a guard to the axle and the barrel, arranged with small perforations 52 between guard ribs 51 such that contact is prevented with either the axle and the barrel for the user.
In the fourth embodiment the head comprises two opposing faces A,B covering the internally situated and vertically arranged barrel and axle or guide wheels.
In the fourth embodiment the housing is formed of two parts, relating to faces of the head wherein the guard extends further down the face of one part. The handle is flared away from the head, such that the guide wheels are perimetric and the handle extends down from the head between them at a waist 57 intermediate the head and handle, and the handle provides a base 56 for standing the device.
In the fourth embodiment the barrel ends are supported in semicircles 87 within the two parts of the head of the housing, in so as to allow rotation thereon or therein. The housing further supports the axle with the semicircles, and provides openings 53 for the guide or first gear wheels to contact external surfaces. The housing may include separation between the guide wheels, barrel and/or spokes; so as to limit clogging in use.
In the fourth embodiment the guard comprises a perforated section of the head. This section follows the barrel circumferential perimeter, so as to provide a regular distance between an outer surface of the guard externally and a cutting position of the blades internally. In this way a regular length of beard or hair may be achieved, by the strands of hair passing through the guard to the blades; if necessary by repeated passes of the head over the user’s skin.
In the fourth pictured embodiment this guard section comprises vertical perforation bars, which bars extend vertically up one face of the head, over the head top 81 and down the opposing face.
In the fourth pictured embodiment the handle extends or depends from the barrel so as to provide a means to manipulate the head. In the pictured embodiments the head and handle follow a linear plane.
In some embodiments articulation may be possible between the head and handle, so as to adjust the plane, or position of the head or handle in relation to the plane.
In the fourth pictured embodiment the blades are arranged longitudinally on the barrel.
In the fourth pictured embodiment the housing is sealed or closed at manufacture, so as to prevent access to the barrel and minimise danger from the blades.
The blades may face in two directions so as to allow cutting in both rotational directions in use, such that the guide may be rotated in either direction. The blades may therefore be comprised by two blades each.
The blades may be twisted or the barrel arranged so as to provide angled blades; and allow helical, progressive or non-linear slicing of hair in use.
In the fourth embodiment the barrel is larger in section than the perimetric barrel gear wheels, such that the barrel is enabled to sit between the guide wheels, and the gear wheels mesh perimetrically.
In the fourth pictured embodiment the barrel comprises a longitudinal core, which core extends from a central axle running between the gear wheels so as to provide a plurality of longitudinally arranged triangular bodies, and a six pointed star in cross section. Each body comprises two extending surfaces and a base, wherein the base comprises the barrel’s axle. The blades are secured to one of the surfaces, and longer than the surface so as to provide a cutting edge. The cutting edge may be inclined towards the surface or away from the surface depending on cutting ability.
With reference to further embodiments the barrel may have a solid core, wherein the blades sit in longitudinal slots.
With reference to still further embodiments the barrel may comprise longitudinal supports for the blades extending between distal discs, which discs driven by the barrel gear wheels, and leave a largely open core. The discs may be joined by an axle such that the blades are supported and cut hair is enabled to pass into the core.
In the pictured embodiment the handle is hollow so as to allow an area for cut hair to accumulate under gravity, during usage.
In the pictured embodiment the handle includes a displaceable portion 54 which portion is situated to the handle end and forms a bung 55. Such bung may be formed in plastics or elastomer such as rubber or silicone. The pictured embodiment includes a grip to aid in its removal from and placement into the handle. The pictured embodiment has a tapered bung so as to progressively friction fit the handle.
The invention has been described by way of examples only and it will be appreciated that variation may be made to the above-mentioned embodiments without departing from the scope of invention.
With respect to the above description then, it is to be realised that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.
Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
