Each figure has showed current preferred razor embodiment.It is to be noted that each figure is not in order to limit scope of invention.
The specific embodiment
Razor comprises forked handle 1 and removable cutter head 2.Handle 1 is used to spur the skin that cutter head slips over the user, it has the shank 3 of a slight bending, and the front end of shank 3 and forked leading section 4 combine, and leading section 4 is generally U-shaped, and a pair of forked arm 6 is arranged, this to forked arm 6 about dividing the imaginary plane mirror image symmetry of shank 3 in longitudinally.By extruding arm 6, they inwardly can be pushed away lightly; In Fig. 1, the dash lines show in left side be the normal position of an arm 6 wherein, and the position that postpones in two arms 6 of solid line illustrated.Arm 6 elastically deformables, so they can automatically revert to the normal position.
In embodiment as shown in the figure, blade 8 is on the cutting plane 12 and is parallel to each other.Each component of the blade 7 have one towards the cutting plane outer surface 13 of 12 projection and the inner surface 14 of a relative depression.The centre position of an imaginary median surface 16 (Figure 10) between inside and outside surface, it is away from cutting plane 12 bendings, and in embodiment as shown in the figure, its a fan-shaped part that is shaped as a cylinder.At blade 8 places, the angle [alpha] between median surface 16 and the cutting plane 12 is preferably at least 15 ° and maximum 30 °, for example 20 °.Segment angle β is preferably 50 °-75 °, more preferably 60 °-70 °.
Each component of the blade 7 is equal crooked and be arranged in and be parallel to each other.This arrangement is convenient to allow waste material (hair follicle and the liquid that shaves) by cutter head (through the recessed side and the protruding side of each blade), and can prevent the excessive buildup of waste material, and this might allow blade 8 lift from the plane of shaving.In order to strengthen this effect, can allow spacing between each trailing edge 9 greater than the spacing between the blade 8.The curvature of component of the blade allows tip 11 to become best angle with the surface of shaving, and the waste material of component of the blade guiding simultaneously leaves the surface of shaving.The crooked outline of component of the blade is strengthened its longitudinal strength, and makes blade distortion minimum in use.
Between second blade part 18 of first blade part 17 below component of the blade 7 is maintained at (in the process of shaving, its is near skin) and top.Blade part 17,18 has crooked blade end support member 19,21 respectively, and they clamp the respective end portions of the component of the blade 7 of the bending between them respectively, the curvature of support member 19,21 and the intrinsic curvature complementation of component of the blade 7.
Support also comprises side element, and its form is the slide block 31 of projection, and in use, it helps to make the surface of shaving to flatten.As clearly shown in Figure 6,32 the plane, surface of shaving is tangent with the element 23,26,31 that forms support, component of the blade 7 relatively, and residing position, this plane has exceeded cutting plane 12, so it helps to proofread and correct shave the relatively position on surface of blade 8.As clearly shown in Figure 3, elongate handgrip 1 is away from 32 the plane, surface of shaving, and becomes suitable angle with it, and leading section 4 begins bending from this plane.For example, axle 3 vertical medial axis and the angle that shaves between the surface 32 can particularly be about 40 ° between 30 °-50 °.This helps the user that razor head is placed on the skin.Combine with forked leading section 4, this is in use convenient especially.
The form of second blade part 18 is the support with forward and backward beam 33,34 and curb girder 36. Bridging element 37,38 extends between forward and backward beam 33,34.Blade support member or spacer 39 that middle bridging element 38 and curb girder 36 are carrying elastically deformable, spacer 39 keeps constant spacing between component of the blade 7, and makes component of the blade in use be out of shape minimum.The form of each deformable spacer 39 elongate component or the finger that hard relatively pin 40 supports of serving as reasons, for instance, this structure is formed by post forming.Two blade parts 17,18 also comprise hard relatively blade support member 41.
In first and second blade parts 17 and 18 each preferably is made of the parts of single global formation, and these parts can be by one-shot forming, post forming or repeatedly moulding formation.Yet as shown in the figure, hairs bar 23 can be a wall scroll.In another embodiment, two blade parts 17,18 can be made of the parts of single global formation, so they are connected by the mode of integral hinge with clam shell.The suitable material that is used to constitute blade part is thermoplastic elastomer (TPE) (is this type of elastomer of Santoprene such as trade mark).For instance, blade part 17,18 is combined by ultra-sonic welded.
On the abutment surface 43 undercutting hole 42 is arranged after the planar shaped of the rear end of the every curb girder 36 of second parts 18 of razor head 2.The end of forked arm 6 has the braking member 44 that the past abutment surface 46 stretches out forward, and preceding abutment surface 46 also is the plane.Each braking member 44 has a shoulder 47, and it is pasting the undercut surface 48 in the hole 42, and forward and backward abutment surface 43,46 mutually near; Like this, the end of the forked relatively arm 6 of razor head 2 just is fixed.This situation is shown in Figure 19-21.
In order to take off razor head 2 from handle 1, two forked arms 6 of extruding relatively earlier, like this, shown in Figure 22 and 23, the shoulder 48 of braking member 44 just with hole 42 in undercut surface 48 disengagings.Shown in Figure 24 and 25, from undercutting hole 42, pull out braking member 44 then.
Although the end of the forked relatively arm 6 of razor head 2 is fixed, in the process of shaving, when revolving force is applied on the razor head, wish that razor head can be around relative shank 3 rotations of the axis that is parallel to blade 8.For this reason, every forked arm 6 all has a transverse concave groove 49, and transverse concave groove 49 stays next integral hinge 51.Two grooves 49 are on the same side of the forked end portions 4 of handle 1, and alignment mutually.Comprising that the arm 52 of groove 49 and braking member 44 and the remainder of forked arm 6 can be (as shown in figure 28) of one, also can be the separate part with axle head 53 perhaps, and axle head 53 is fixed in the remaining part of forked arm 6.
The parts that comprise groove 49 are enclosed in the material 54 (such as thermoplastic elastomer (TPE)) of elastically deformable, on the surface of the latter attached to deformable component.As clearly shown in Figure 28, for example, the part of abutment surface 46 before material 54 defines.In the process of shaving, when revolving force was applied on the razor head 2, the material of the elastically deformable in the groove 49 was tightened up (thereby permission groove 49 opens and allow razor head 2 to rotate), and when this power of removal, razor head 2 just is returned to its normal position.
The axle 3 of handle 1 has the grip zone 59 that extends around axle 3.Grip zone 59 has many small embossments 61 of gripping of helping.Grip zone 59 can be made by the material different with the remainder of axle 3, particularly can be softer, and higher coefficient of friction can be arranged.The main body of handle 1 comprises arm 6, can be made by the material of elastically deformable, and therefore with thumb and the forked part 4 of all the other finger extruding, it is as a whole crooked in opposite directions that two arms 6 are done.Yet the main body of handle 1 can be made by hard relatively material, and in this case, each forked arm 6 can comprise end portion relatively flexibly, and the latter is fixed on the hard relatively proximal part, and the latter comprises groove 49.The basis handle can for example be used thermoplastic elastomer (TPE), polypropylene, styrene or polythene copolymer plastics, the cast metal such as aluminium or the synthetic material such as carbon fiber by any suitable material injection mo(u)lding.The handle of being made by thermoplastic elastomer (TPE) can have the grip zone of being made by softer thermoplastic elastomer (TPE) (for example passing through double injection molding).For instance, the handle with carbon fiber production can have the grip zone of being made by aluminium or timber.
In the alternate embodiments shown in Figure 30-32, groove 49 is positioned at the upside of the leading section 4 of handle 1, and when therefore applying revolving force, the material 54 of the elastically deformable in each groove 49 can be compressed.
Can make various improvement within the scope of the invention.For example, although above-described razor head has three component of the blade, this is preferred number, also can use single component of the blade, a pair of component of the blade or four even more component of the blade.Each blade can be in suitable angle.Component of the blade can have all thickness.Radius of curvature can change, and particularly, can descend along the direction away from blade.Except the component of the blade of bending, can also use the straight component of the blade or the component of the blade of bending.Component of the blade is except having fixing (permanent) curvature and being installed on the stayed surface of cutter head with (aforesaid) identical curvature, can also use original with regard to straight component of the blade, they have enough flexible, therefore in a single day be installed on the cutter head, they will bend to required curvature.Groove can be positioned on the single arm, and the latter forms the leading section of handle.Hinge with other any conventionally forms replaces the groove on the forked arm also can make the razor head rotation.Razor head can be permanently secured on the handle, and in this case, component of the blade can be installed on changeable type ground, and whole in other words razor can be disposable.
