In addition, as being explained in greater detail herein, at least one embodiment, blade holder 22 can be constructed Into around pivot axis P A rotations about 180 degree or more so that user can select the front surface 140 of blade holder 22 or rear table Face 156.For example, blade holder 22 can on front side of it 140 and 156 the two of rear side on including shaving (shave) blade (see, e.g. Fig. 5 or Fig. 8).Optionally (or in addition), blade holder 22 can be included in the shaving of front side 140 and (shave) blade and in rear side 156 Mirror.

According to one embodiment, pivot offset mechanism 90 can optionally include actuating button 100.Activate button 100 Bar 92 can be attached to, and can be configured to generally along the direction retraction bar 92 opposite with arrow C (see, e.g. Fig. 3 and Fig. 5) and blade holder 22 around pivot axis P A rotate about 180 degree (or more) when leave the path of blade holder, such as exist It is generally shown in Fig. 4.For example, actuating button 100 can be in the guide rail 102 provided by the elongated slot being formed in handle 60 It advances in (Fig. 6 A and Fig. 6 B).User can push actuating button 100 so as to foot along the direction generally opposite with arrow C Enough power retraction bars 92 to compress bias unit 96,98, thus make cylindrical bar 92 retract it is remote enough (for example, generally along with Opposite arrow C direction and generally leave blade holder 22) allow blade holder 22 for example along and bar 92 biased direction Generally opposite direction (for example, R2 directions in R1 directions and Fig. 5 in Fig. 3 to Fig. 4) around pivot axis P A rotations about 180 degree (or more) without contacting bar 92.It should be appreciated that although pivot offset mechanism 90 is shown in Fig. 6 A and Fig. 6 B in handle 60 outside, but a part of of pivot offset mechanism 90 can be located in the interior zone of handle 60, such as herein substantially Upper explanation.

According to another embodiment, replaceable head assembly 20 can optionally include one or more blade holders and rotate When limited part 35, one or more blade holder rotation inhibitors are configured to side 140 before use or rear side 156 generally Blade holder 22 is limited relative to handle 60 and/or the rotating range of Cartridge support component 24.Blade holder rotation inhibitor 35 can It is enclosed (in Figure 5) along direction of rotation R2 (in Fig. 3 to Fig. 4) or direction of rotation R1 with being configured to be substantially impeded from blade holder 22 Specific/predetermined point (swing) is pivoted beyond around pivot axis P A.Blade holder rotation inhibitor 35 can be configured to greatly as a result, It is more than predetermined point that rotation is prevented on body.

With reference to Fig. 3, an embodiment of the blade holder rotation inhibitor 35 according to the disclosure is generally illustrated.Blade Frame rotation inhibitor 35 can include elasticity, deformable stop dog component or pawl 36, the stop dog component or pawl are constructed Into the opposite side of blade holder 22 used in contact.For example, once blade holder 22 surrounds pivot axis P A pivots along direction of rotation R2 Turn to be more than specific/predetermined point (swing), deformable pawl 36 can contact blade holder at the position below pivot axis P A 22 sword region.Although deformable pawl 36 is shown as from support hub 50 extending outwardly and contacting one of blade holder 22 Point, but it is to be understood that this arrangement can be opposite.For example, deformable pawl 36 can also be configured to from blade Frame 22 extends outwardly with the part for contacting support hub 50.

In order to make blade holder 22, around pivot axis P A rotations, about 180 degree or more, pin 92 can as in Fig. 4 generally Retraction as showing, and blade holder 22 can be rotated along R1 directions.When blade holder 22 is rotated along R1 directions, blade holder 22 Pawl 36 will be contacted.Pawl 36 (it can be formed by the polymer composition of such as elastomer or sheet metal) will deform downwards (for example, generally toward hub 50 and/or support arm 30 of braced frame 26) is to allow blade holder 22 to continue to rotate along R1 directions. Once blade holder 22 passes through pawl/elastically deformable stop dog component 36, stop dog component 36 will return to its initial position, and Blade holder 22 is prevented along direction of rotation R2 back rotations.The elastically deformable stop dog component 36 allows blade holder 22 along a side To rotation, but blade holder 22 is prevented to rotate in opposite direction.(as described above) again, although pawl 36 is shown as from branch Support frame frame 26 extends, but pawl 36 can also extend from blade holder 22 and similarly can surround pivotal axis in blade holder 22 Line PA is resiliently deformed when rotating.

Referring again to Fig. 5 and Fig. 7, another implementation of the blade holder rotation inhibitor 35 according to the disclosure is generally illustrated Mode.Blade holder rotation inhibitor 35 can include elasticity, deformable stop dog component or pawl 36, the stop dog component or spine Pawl is configured to contact one or more in multiple teeth 37.In embodiment shown in Fig. 5 and Fig. 7, pawl 36 Generally radially extend outwardly from pivotal pin 34, and tooth 37 generally radially extends internally from receptacle 32 is pivoted；So And, it should be understood that the arrangement of pawl 36 and tooth 37 can be converted, and pawl 36 can be from pivot receptacle 32 generally diametrically Ground extends internally, and tooth 37 generally radially extends outwardly from pivotal pin 34.

As being best shown in the figure 7, pivotal pin 34 is along the first direction (for example, the edge in shown embodiment R2 directions) around pivot axis P A rotation may cause to pawl 36 contact the first tooth 37a it is support with favored policy, taper, curved Song, raised, recess and/or bowed part (for example, first part) 39, so as to which pawl 36 be caused to be resiliently deformed (for example, being generally radially deformed inward in shown embodiment) leaves the path of the first tooth 37a and allows pivot 34 continuation of shipping and reselling on another market rotate along the first direction around pivot axis P A.Conversely, pivotal pin 34 is in a second direction (for example, shown Embodiment in along R1 directions) may cause to pawl 36 around the rotation of pivot axis P A and contact the second tooth 37b (for example, phase Adjacent tooth) drastically inclined, upright and/or generally vertical part (for example, second part) 41, so as to cause pawl The second part 41 of 36 soldered tooth 37b and substantially prevented from pivotal pin 34 in a second direction around pivot axis P A arbitrarily into one Step rotation is more than the predetermined point limited by the second tooth 37b.According to one embodiment, pivotal pin 34 can be adjacent by two It is generally rotated in the region 43 that tooth (for example, tooth 37a, 37b) limits freely about pivot axis P A.Region 43 can also be by It is considered recess portion.

It should be appreciated that in arbitrary embodiment as described herein, spacing between tooth can than it is illustrated go out Bigger and/or smaller, this is by the bigger for allowing blade holder head and/or smaller swing.

Shaving knife 10 can optionally include anti-pivot.The anti-pivot can be configured to allow for user to make Blade holder 22 rotates to select one in multiple side/faces, and allow blade holder 22 in scheduled rotation around pivot axis P A In the range of rotate, and during normal use shaving knife at blade/facial positions of selection be suitble to user skin wheel It is wide.According to one embodiment, anti-pivot can include (the such as, but not limited to offset pins of blade holder pivot offset mechanism 90 And/or blade holder rotation inhibitor 35 (such as, but not limited to pawl 36 and multiple teeth 37) 92).Offset pins 92 can be configured to (for example, along R1 directions in shown embodiment) pushes blade holder 22 in a second direction so that 36 Contact Tooth 37b of pawl Generally vertical part 41, so as to limit blade holder 22 in a second direction (for example, R1) rotate.Offset pins 92 can also be big Blade holder 22 is prevented on body, and (for example, R2 directions) is rotated around pivot axis P A more than predetermined point along the first direction, unless such as this The text offset pins 92 move away the path of blade holder 22.

With reference to Fig. 5 and Fig. 7, user (for example, R2) can apply shaving power Fsu along the first direction, this causes blade holder (for example, R2) resists the spring force of offset pins 92 and rotates 22 (and therefore pivotal pin/cylinders 34) along the first direction, and And pawl 36 is caused to move away the generally vertical part 41 of tooth 37b.Once power Fsu is reduced/removes, offset pins 92 Power (for example, resistance Fres) cause pivotal pin/cylinder 34 be moved back to towards initial initial position (for example, wherein pawl 36 against/ The generally vertical part 41 of Contact Tooth 37b).

In order to rotate blade holder 22 to select different face (for example, face 140 or face 156), user can be as herein Then the path that offset pins 92 is made to be retracted away from blade holder 22 can make blade holder 22 along the first direction (for example, R2 side To) rotation, pawl 36 is thus caused to be resiliently deformed the path for leaving tooth 37a and pivotal pin 34 is allowed to continue along the first direction (for example, R2) is rotated around pivot axis P A.Once user discharge offset pins 92, offset pins 92 in a second direction (for example, R1 blade holder 22) is pushed, until the generally vertical part 41 of 36 Contact Tooth 37 of pawl.Blade holder 22 is around pivot as a result, The rotation of axis PA is generally limited to the region between two teeth 37 adjacent with pawl 36.

Again, it should be appreciated that pawl 36 and tooth 37 can be converted relative to the arrangement of pivotal pin 34 and receptacle 32, and Therefore, the arrangement (that is, orientation of first part 39 and second part 41) of tooth 37 and the gradient of pawl 36 can be converted.Separately Outside, the arrangement (that is, orientation of first part 39 and second part 41) of tooth 37 and the gradient of pawl 36 can be according to offset pins 92 are configured to push the direction (for example, R1 or R2) of blade holder 22 and convert.For example, in Fig. 5 and embodiment party illustrated in fig. 7 In formula, offset pins 92 are configured to push blade holder 22 in a second direction (for example, R1 directions).However, as described herein another (for example, with reference to Fig. 3 and Fig. 8) in some embodiments, offset pins 92 are configured to (for example, R2 directions) promotion along the first direction Blade holder 22, and the first part 39 of tooth 37 and the orientation of second part 41 and the gradient of pawl 36 can be relative to Fig. 5 With the position conversion shown in Fig. 7.

For example, referring to Fig. 8, pivotal pin 34 along the first direction enclose by (for example, along R2 directions in shown embodiment) Rotation around pivot axis P A may cause to pawl 36 and contact the drastically inclined, upright and/or generally perpendicular of the first tooth 37a Straight part (for example, second part) 41, so as to which pawl 36 be caused to engage the second part 41 of the first tooth 37a and generally prevented Only (for example, R2) is arbitrarily further rotated around pivot axis P A more than being limited by the first tooth 37a pivotal pin 34 along the first direction Predetermined point.Conversely, pivotal pin 34 in a second direction (for example, along R1 directions in shown embodiment) around pivotal axis The rotation of line PA may cause to support with favored policy, taper, the bending that pawl 36 contacts the second tooth 37b (for example, adjacent tooth) , raised, recess and/or bowed part (for example, first part) 39, left so as to which pawl 36 be caused to be resiliently deformed The path (for example, being generally radially deformed inward in shown embodiment) of second tooth 37b and allow pivotal pin 34 continue to rotate around pivot axis P A in a second direction.According to one embodiment, pivotal pin 34 can be adjacent by two Tooth (for example, tooth 37a, 37b) limit region 43 in generally freely about pivot axis P A rotate.

Offset pins 92 can be configured to (for example, along R2 directions in shown embodiment) promotion along the first direction Blade holder 22 so that the thus generally vertical part 41 of 36 Contact Tooth 37a of pawl limits blade holder 22 along the first direction The rotation of (for example, R2).Offset pins 92 can also substantially prevented from blade holder 22 in a second direction (for example, R1 directions) around pivot Shaft axis PA rotations are more than predetermined point, unless offset pins 92 as described herein move away the path of blade holder 22.

During shaving knife 10 is used, user (for example, R1) can apply shaving power Fsu in a second direction, this causes Blade holder 22 (and therefore pivotal pin/cylinder 34) in a second direction (for example, R1) resist offset pins 92 spring force and Rotation, and pawl 36 is caused to move away the generally vertical part 41 of tooth 37a.Once power Fsu is reduced/removes, partially Putting the power (for example, resistance Fres of offset pins 92) of pin 92 causes pivotal pin/cylinder 34 to be moved back to (example towards initial initial position Such as, wherein pawl 36 is against the generally vertical part 41 of/Contact Tooth 37a).

In order to rotate blade holder 22 to select different face (for example, face 140 or face 156), user can be as herein The path that offset pins 92 is made to be retracted away from blade holder 22 (see, e.g. Fig. 4), then can make blade holder 22 (Fig. 8) edge Second direction (for example, R1 directions) rotates, and pawl 36 is thus caused to be resiliently deformed the path for leaving tooth 37b and allows to pivot Pin 34 continues to rotate around pivot axis P A in a second direction (for example, R1).Once user discharges offset pins 92, offset pins 92 (for example, R2) pushes blade holder 22 along the first direction, until the generally vertical part 41 of 36 Contact Tooth 37 of pawl.As a result, Blade holder 22 is generally limited to the region between two teeth 37 adjacent with pawl 36 around the rotation of pivot axis P A.

Turning now to Fig. 9 and Figure 10, another embodiment of anti-pivot is generally illustrated.The anti-pivot can With include blade holder pivot offset mechanism 90 (such as, but not limited to offset pins 92) and/or blade holder rotation inhibitor 35 (such as But it is not limited to pawl/spiral pawl 36 and multiple teeth 37).In shown embodiment, the spiral spine that is resiliently deformable Pawl 36 generally radially extends outwardly from pivotal pin 34, and receptacle 32 include it is multiple towards pivotal pin 34 generally diametrically The tooth 37 that ground extends internally.It will be appreciated, however, that spiral pawl 36 and tooth 37 are relative to pivotal pin 34 and the arrangement of receptacle 32 It can convert, and spiral pawl 36 can generally radially extend internally from receptacle 32, and tooth 37 can be from pivot Pin 34 generally radially extends outwardly.

Offset pins 92 can be configured to (for example, along R1 directions in shown embodiment) promotion in a second direction Blade holder 22 so that the generally vertical part 41 (Figure 10) of the distal end Contact Tooth 37a of pawl 36 thus limits blade holder 22 The rotation of (for example, R1) in a second direction.Offset pins 92 can also be substantially prevented from blade holder 22 along the first direction (for example, R2 Direction) it is rotated around pivot axis P A more than predetermined point, unless offset pins 92 as described herein move away the road of blade holder 22 Diameter.

During shaving knife 10 is used, user (for example, R1) can apply shaving power Fsu in a second direction, this causes Blade holder 22 (and therefore pivotal pin/cylinder 34) in a second direction (for example, R1) resist spiral pawl 36 spring force And it rotates.Once power Fsu is reduced/removes, the power (for example, spin resistance Fres) of spiral pawl 36 causes pivotal pin/cylinder Body 34 is moved back to (for example, the wherein power of offset pins 92 and spiral pawl 36 is essentially equal) towards initial initial position.

User (for example, R2) can also apply shaving power Fsu along the first direction, cause (and the therefore pivot of blade holder 22 Ship and resell on another market/cylinder 34) resist the spring force of offset pins 92 and (for example, R2) rotates along the first direction, and optionally causes Pawl 36 moves away the generally vertical part 41 of tooth 37a.Once power Fsu is reduced/removes, the power (example of offset pins 92 Such as, resistance Fres) pivotal pin/cylinder 34 is caused to be moved back to towards initial initial position (for example, wherein offset pins 92 and spiral spine The power of pawl 36 is essentially equal).

In order to rotate blade holder 22 to select different face (for example, face 140 or face 156), user can be as herein The path that offset pins 92 is made to be retracted away from blade holder 22 (see, e.g. Fig. 4), then can make blade holder 22 along second party It is rotated to (for example, R1 directions), leaves the path of tooth 37a so as to which spiral pawl 36 be caused to be resiliently deformed and allow pivotal pin 34 continue to rotate around pivot axis P A in a second direction (for example, R1).Once user discharges offset pins 92,92 edge of offset pins Second direction (for example, R1) pushes blade holder 22, until the generally vertical part of the distal end Contact Tooth 37 of spiral pawl 36 41.Blade holder 22 is generally limited to the area between two teeth 37 adjacent with pawl 36 around the rotation of pivot axis P A as a result, Domain (that is, being controlled by position).

Although offset pins 92 and spiral pawl 36 are shown as pushing knife along R1 directions and R2 directions in figure 9 and in figure 10 Horse 22, but it is to be understood that offset pins can be configured to push blade holder 22 along R2 directions, and spiral pawl 36 can be by structure It causes to push blade holder 22 along R1 directions, and the orientation of tooth 37 can also be converted.According to the disclosure, ordinary skill Personnel will be understood that such change.

Turning now to Figure 11 and Figure 12, the another embodiment of anti-pivot is generally illustrated.Anti- pivot It can include blade holder pivot offset mechanism 90 and blade holder rotation inhibitor 35.As indicated herein, the anti-pivot User is configured to allow for make blade holder 22 (for the sake of clarity merely illustrating pivotal pin/cylinder 34) around pivot axis PA rotates to select one in multiple side/faces, and blade holder 22 is allowed to rotate in scheduled rotating range, while just It often uses during shaving knife at blade/facial positions of selection to be suitble to the contoured skin of user.

In shown embodiment, blade holder pivot offset mechanism 90 and blade holder rotation inhibitor 35 can include Bias unit 200 (such as, but not limited to torsionspring etc.), which, which has, is attached to the first end of arm 30 and by structure Cause the second end of pivot cylinder 202 that (for example, direction of rotation R2) is biased around pivot axis P A promotions along the first direction Portion.The pivot cylinder 202 of biasing includes pawl 204.Pawl or elastic pawl 204 can be from the pivot cylinders 202 of biasing Generally radially extend outwardly.Bias unit 200 (for example, R2) can push the pivot cylinder biased along the first direction 202 so that the pawl 204 of the pivot cylinder 202 of biasing engages the first tooth 206A, and (it can be configured to from pivotal pin/cylinder Body 34 generally radially extends internally), so as to which (for example, R2) pushes pivotal pin/cylinder 34 along the first direction, and causes (it can be configured to from pivotal pin/cylinder 34 generally diametrically one or more pivot cylinder stop dog components 207,209 Ground extends outwardly) respectively engagement arm 30 one or more arm stop dog components 208,210.Pivot cylinder stop dog component 207, 209 generally limit pivotal pin/cylinder 34 (and therefore blade holder 22) along first with the engagement of arm stop dog component 208,210 The rotation in direction (for example, R2), while blade holder 22 is set at the first blade face position (for example, blade holder 22 is relative to hand The position of handle 60, the position correspond to the first face of blade holder 22 that the user of shaving knife 10 operationally uses).For example, It pivots cylinder stop dog component 207,209 and the engagement of arm stop dog component 208,210 is generally being set in the first blade position While set blade holder 22 initial initial position.

During shaving knife 10 is used, (for example, R1) applies shaving power Fsu to user in a second direction, this causes blade (for example, R1) resists the spring force of bias unit 200 and revolves frame 22 (and therefore pivotal pin/cylinder 34) in a second direction Turn, arm stop dog component 208,210 is moved away from so as to cause to pivot cylinder stop dog component 207,209.Once power Fsu quilts Reduction/removal, the power (for example, resistance Fres) of bias unit 200 cause pivotal pin/cylinder 34 towards initial initial position (as shown in figure 11) is moved back to.

In order to which blade holder 22 is made to rotate to another blade face position (for example, opposite with one of the other faces of blade holder 22 Second or the third blade face position answered), by rotary force Fr, (for example, R2) applies to blade holder 22 user along the first direction, It is deformed above arm stop dog component 208,210 respectively so as to cause to pivot cylinder stop dog component 207,209, until pivoting cylinder Body stop dog component 207,209 contacts again with arm stop dog component 208,210 respectively.In addition, rotary force Fr causes the pivot of biasing Cylinder 202 is slightly rotated around pivot axis P A until pawl 204 deforms, and pawl 204 and tooth above tooth 206B Generally vertical/upright part contact of 206B.Therefore, blade holder 22 can rotate about 180 degree so that user can make With the opposing face of blade holder 22.

It should be appreciated that although Figure 11 to Figure 12, which is shown, is configured to allow for user between two faces of blade holder 22 The anti-pivot of selection is carried out, but the anti-pivot can be configured to allow for user in blade holder 22 more than two It is selected between a face.Particularly, support arm 30 can include stop dog component 208,210 spaced apart so that pivot cylinder Body stop dog component 207,209 can contact one at the position corresponding to the initial initial position of first, second and at least third Or more arm stop dog component 208,210.First, second and at least initial initial position of third correspond respectively to blade holder 22 First, second and at least third face.In addition (or optionally), it should be understood that rotary force Fr may cause to arm stop dog component 208, 210 are pivoting deformation above cylinder stop dog component 207,209 respectively, distinguish until pivoting cylinder stop dog component 207,209 It is contacted again with arm stop dog component 208,210.As a result, arm stop dog component 208,210 and/or pivot cylinder stop dog component 207, 209 can be resiliently deformable.In addition, it should be understood that pivotal pin/cylinder 34 and/or the pivot cylinder 202 of biasing It can include being constructed such that pivotal pin/cylinder 34 and/or the pivot cylinder 202 biased relative to each other and/or prop up The supporting surface (being for the sake of clarity not shown) of receptacle alignment in brace 30.

With reference to Figure 13 and Figure 14, another embodiment of anti-pivot is generally illustrated.The anti-pivot allows User makes blade holder 22 (for the sake of clarity merely illustrating pivotal pin/cylinder 34) rotate to select around pivot axis P A One in multiple side/faces, and allow blade holder 22 during normal use shaving knife at blade/facial positions of selection It is rotated in scheduled rotating range, to be suitble to the contoured skin of user.

The anti-pivot can include at least one pawl or elastic pawl 220, and the pawl or elastic pawl are constructed It generally radially extends internally into from the receptacle 32 of arm 30.Pivotal pin/cylinder 34 can include multiple recess portions 222, should Multiple recess portions are configured to receive the distal end 224 of pawl 220.According to one embodiment, the distal end 224 of pawl 220 can have There is the shape for the part for substantially corresponding to recess portion 222A, to help to keep pawl 220 relative to recess portion 222A.For example, Distally 224 can have generally spherical in shape shape, and recess portion 222A can include the part with generally hemispherical shape 226, the diameter of the part is substantially equal to distal end 224.The position of recess portion 222 may both correspond to one in multiple faces of blade holder 22 It is a.Therefore, although merely illustrating two recess portions 222A, 222B, but it is understood that, pivotal pin/cylinder 34 can include With three or more corresponding recess portions 222 of three or more faces of blade holder 20.

It should be appreciated that in arbitrary embodiment as described herein, the length of pawl and/or the depth of recess portion and/or width Degree can be than illustrated bigger and/or smaller, this will allow bigger of the blade holder head in scheduled rotating range Swing and/or smaller swing.

As will be appreciated, the design of the length of pawl and flex/stiffness combination recess portion can determine blade holder phase For the swing (for example, predetermined rotating range) with the corresponding initial initial position in the face of selection.

With reference to Figure 15, the modification of the anti-pivot of Figure 13 and Figure 14 is generally illustrated.The anti-pivot of Figure 15 with Figure 13 is similar with the anti-pivot of Figure 14；However, pawl 220 is configured to from pivotal pin/cylinder 34 generally radially Extend outwardly, and be configured to a recess portion of the selection that engagement is formed in multiple recess portions 222 in arm 30.

(Figure 13 to Figure 15) in practice, user can revolve blade holder 22 (and therefore pivotal pin/cylinder 34) Turn so that the desired face of blade holder 22 is in appropriate position relative to handle 60.Once in target location, pawl 220 Distal end 224 can be accepted in recess portion 222A (such as, but not limited to holding part 226).The arrangement can be defined as initially Initial position.When applying shaving power Fsu to blade holder 20 (and therefore pivotal pin/cylinder 34), the application of pawl 220 is supported The resistance Fres of anti-blade holder 22 pushes blade holder 22, and rise generally toward initial along the direction opposite with shaving power Fsu Beginning position.Therefore, blade holder 22 can rotate in a certain range relative to initial initial position around pivot axis P A.

Turning now to Figure 79 to Figure 80, the opposing party of the head assembly 20 and handle 60 according to the disclosure is generally illustrated Face, the head assembly 20 and handle 60 are configured to be linked together using one or more magnets.Particularly, Figure 79 is substantially On show head assembly 20 and handle 60 in unassembled state, and Figure 80 generally illustrates the head in assembled state Parts 20 and handle 60.It should be appreciated that magnetic connection as described herein can be with arbitrary head well known by persons skilled in the art Parts are used together, and the arbitrary head assembly includes but not limited to arbitrary head assembly as described herein.

Although the embodiment described in Figure 77 to Figure 78 can utilize magnetic attracting force by head assembly 20 and handle 60 Be linked together (for example, the magnetic poles of one or more magnets 7702,7704 is aligned so that magnetic field generate attraction so as to Push head assembly 20 and handle 60 toward each other), but the head assembly 20 of Figure 79 to Figure 80 and handle 60 include at least two A magnet (for example, central magnet 7902 and toroidal magnet 7904), the magnetic pole alignment of the magnet so that their magnetic field generates The magnetic repulsive force for being as described herein linked together head assembly 20 and handle 60.

For example, head assembly 20 can include protruding portion (for example, head stub) 7906, the protruding portion include one or More central magnets 7902, the central magnet are configured to be accepted in chamber (for example, handle chamber) at least partly In 7908, the chamber includes one or more toroidal magnets 7904, and the central magnet is further configured at least partly Ground is accepted in the middle section of toroidal magnet 7904.Toroidal magnet 7904 can include one or more annulars, ring-type And/or the magnet (for example, permanent magnet and/or electromagnet) of toroid (for example, circle, annular, plate-like etc.) shape.Optionally (or in addition), toroidal magnet 7904 can be included with substantially ring-like, cyclic annular and/or toroid (for example, round, annular, disk Shape, round etc.) multiple (for example, array) magnets of setting are constructed to generate substantially ring-like, cyclic annular and/or toroid magnetic field (for example, with the magnetic field for forming substantially ring-like, cyclic annular and/or toroid pattern magnetic field line).Central magnet 7902 can be with Including any magnet (for example, permanent magnet and/or electromagnet), such as, but not limited to disc-shaped magnet etc..

As set forth above, it is possible to using the repellency magnetic force between head assembly magnet 7902 and handle magnet 7904 by head Component 20 and handle 60 are linked together.Particularly, inventor has found, if central magnet 7902 and the (tool of toroidal magnet 7904 Have the inside dimension ID7910 of the external dimensions OD7912 equal to or more than central magnet 7902) it is confined to along 7914 phase of axis For generally axially being moved each other (for example, by means of the OD7916 of protruding portion 7906 relative to chamber 7908 ID7918) so that central magnet 7902 can be to pass through the middle section 7920 of toroidal magnet 7904, and is further oriented So that magnetic pole is towards the same direction along axis 7914, then obtained power relative to displacement curve relationship (see, for example, Figure 81 A to Figure 81 B) it is closely similar with traditional mechanical stop member.

Particularly, it with reference to Figure 81 A and Figure 81 B, generally illustrates and illustrates central magnet 7902 relative to toroidal magnet The figure of 7904 displacement (for example, mobile) and obtained magnetic force (for example, into or leave chamber 7908).Reference Figure 81 A, When magnet 7902,7904 is closer to each other along direction 8100 along axis 7914 (for example, head assembly 20 advances towards handle 60), The repulsive force F generated by the magnetic field 8102,8104 between them generates resistance head assembly 20 by and is moved towards chamber 7908 Dynamic power (for example, region 8106), and the power with central magnet 7902 close to toroidal magnet 7904 and increase (for example, increase Add), then when magnet 7902,7904 is aligned at the C of position (for example, the magnetic field 8102,8104 of magnet 7902,7904 by that This balance, and will not substantially generate the power that head assembly 20 and blade 60 are pushed along axis 7914) start to reduce (such as base It is reduced to zero) on this.It is understood that when central magnet 7902 and toroidal magnet 7904 are aligned at the C of position, realize Unstable balance.Make central magnet 7902 and toroidal magnet 7904 is stopped and may be difficult in the position.It is this unstable Balance be the reason of causing brake feel.

With reference to Figure 81 B, with magnet 7902 along axis 7914 continue along direction 8100 move through position C (for example, they Begin to pass the middle section 7920 of toroidal magnet 7904), the repulsive force F phases generated by the magnetic field 8102,8104 between them Region 8106 is converted and generates the power (for example, region 8108) that head assembly 20 is pushed towards handle 60.The region 8108 Power start sustainable growth, until magnetic field starts to dissipate.In region 8108, power starts that central magnet 7902 is pushed to leave annular Magnet 7904, so as to push head assembly 20 towards handle 60.It is driven from user by the angle of head assembly 20 towards handle 60 It is dynamic to see, feel be the middle section 7920 and opposite direction that toroidal magnet 7904 is passed through with central magnet 7902 repulsive force Dominant (take over), initial resistance increases to peak force, is followed by " assisting ".If hard stop part is properly placed (for example, being surrounded by means of the base regions contact of the base portion, protruding portion 7906 of the distal end contact chamber 7908 of protruding portion 7906 logical Proximal face and/or the conical surface of protruding portion 7906 and chamber 7908 to the opening of chamber 7908 are in contact with each other, protruding portion 7906 " bottom out (bottom out) " relative to chamber 7908), then the repulsive force in region 8108 will make head group Part 20 is against handle 60, so as to cause the firm holding between head assembly 20 and handle 60.

The connection of repellency magnetism is the magnetic field line across the central magnet 7902 of the middle section 7920 of toroidal magnet 7904 Between interaction feature result (for example, exist in the middle section 7920 of toroidal magnet 7904 with from ID and OD Between face (for example, plane) transmitting magnetic field line magnetic field line opposite on direction).As a result, as central magnet 7902 connects The ID (Figure 81 A) of nearly toroidal magnet 7904, even if the magnetic pole of central magnet 7902 and toroidal magnet 7904 is with opposite magnetic pole court Orient (if there is no hole or middle section 7920 in toroidal magnet 7904, then this will cause attractability magnetic force) to each other, The magnetic field 8104 of toroidal magnet is opposite with the magnetic field 8102 of central magnet 7902 in ID, leads to repellency magnetic force.Again, it should manage Solution, if substituting toroidal magnet 7904 with the multiple discrete magnets for being arranged to automatic adjustment array, then can generate Identical effect.

Figure 79 and Figure 80 are rotated back into, optional auxiliary magnet 7922 can be arranged near the base portion of chamber 7908.It is auxiliary Magnetic assist body 7922 can have the magnetic pole being aligned relative to central magnet 7902, in auxiliary magnet 7922 and central magnet 7902 Between generate attractability magnetic force.Attractability magnetic force between central magnet 7902 and auxiliary magnet 7922 can further increase head Retentivity between component 20 and handle 60, while still keep user that can be undergone during head assembly 20 is inserted into handle 60 Uniqueness " braking " feature.

In shown embodiment, toroidal magnet 7904 and chamber 7908 are a parts for collar 7714, but it should Understand, this is not the limitation to the disclosure, unless special requirement are such.Although in addition, it will be appreciated that head assembly 20 and handle 60 are shown as with the head stub 7906 being accepted in handle chamber 7908, but this arrangement can overturn (example Such as, head assembly 20 can include the head assembly chamber with toroidal magnet 7904, and handle 60 may include with central magnet 7902 handle tabs), and those skilled in the art will appreciate that any additional change based on the disclosure.

Turning now to Figure 82, another embodiment party of the magnetic connection between head assembly 20 and handle 60 is generally illustrated Formula.Magnetism connection can be similar to the arrangement shown in Figure 79 and Figure 80, in addition to that can use 8202 generation of floating/repulsive magnets For optional auxiliary magnet 7922.Particularly, compared with auxiliary magnet 7922, floating/repulsive magnets 8202 can make its magnetic pole It is reverse, so as to repel rather than attract central magnet 7902.Floating/repulsive magnets 8202 so that central magnet (and therefore Head assembly 20) balance at point between toroidal magnet 7904 and floating/repulsive magnets 8202 (or hovering or float).If Suitable gap or space 8404 are stayed between the matching surface of head assembly 20 and handle 60, then head assembly 20 will appear to Axially float along axis 7914, and always back to equalization point after deflection, so as to for shave doctor blade system 10 assign it is small Damping effect.Therefore, head assembly 20 can be axially moved along axis 7914 in space 8404.It is understood that with It central magnet 7902 to be driven towards floating/repulsive magnets 8202, the repulsive force between them is with 7902 He of central magnet Floating/repulsive magnets 8202 draw closer together and increase, until central magnet 7902 touch feel be hard stop part point.This is very Good the simulation following behavior of compressed spring, the resistance of compressed spring increase with displacement, until being finally reached pressure and high Degree.

It is similar to Figure 79 to Figure 80, it should be understood that be accepted in although head assembly 20 and handle 60 are shown as having Head stub 7906 in handle chamber 7908, but this arrangement can be overturned (for example, head assembly 20 can include tool There are toroidal magnet 7904 and the head assembly chamber of floating/repulsive magnets 8202, handle 60 can include having central magnet 7902 handle tabs), and those skilled in the art will appreciate that any additional change based on the disclosure.Space 8404 can optionally be resiliently deformable sheath (sock), the coverings such as shield (gaiter).In addition, it will be appreciated that this Magnetic connection described in text can be used together with arbitrary head assembly well known by persons skilled in the art, the arbitrary head Component includes but not limited to arbitrary head assembly as described herein.

As described herein (see, e.g. Figure 79 to Figure 82 and corresponding description), make central magnet 9312 and toroidal magnet 9316 magnetic pole alignment so that repellency magnetic force is generated between magnet 9312,9316, thus by 24 He of Cartridge support component Handle 60 pushes together.Handlebar 9302 and supporting member chamber 9304 (and optionally lock-in feature 9306,9308 and/ Or non-circular cross sections) interaction and the combination of repellency magnetic force can be generally by Cartridge support component 24 and handle 60 are fixed relative to each other and/or install, so as to form connection between them.

Blade holder 22 can be pivotably coupled to one or more arms 30 of Cartridge support component 24, and can To include being arranged on one or more shaving blades 9322 on one or more faces 9324.In shown embodiment In, blade holder 22 is included in multiple shaving blades 9322 on the first face 9324.Opposite face 9326 can include one or more Multiple blade holder magnets 9318.Although blade holder magnet 9318 is shown in the centre in opposite face 9326, but it is to be understood that one A or more blade holder magnet 9318 can be arranged on face 9326 anywhere.

The magnetic pole of blade holder magnet 9318 is aligned with the magnetic pole of central magnet 9312, to be joined in Cartridge support component 24 Repellency magnetic force (for example, as shown in Figure 94 and Figure 95 generally) is generated when being connected to handle 60.Repellency magnetic force can be with Generally push blade holder 22 leave yoke portion 47 and/or handle 60, for example, as arrow 9402 generally shown in.Blade holder Supporting member 24 and/or blade holder 22 can include setting blade holder 22 relative to Cartridge support component 24 and handle 60 just One or more ISP (initial initial position) protruding portion, shoulder, spine and/or extension of beginning initial position (ISP) 9328.It is appreciated that ISP be in the case of no applied force blade holder 22 relative to Cartridge support component 24 and handle 60 Position and blade holder 22 returns to after the external force is removed position.In other words, when during shaving external force be applied to During blade holder 22, external force can overcome the repellency magnetic force between blade holder magnet 9318 and central magnet 9312 so that blade Frame 22 is moved along direction generally opposite with arrow 9402.When external force is removed and/or is reduced, 9318 He of blade holder magnet Repellency magnetic force between central magnet 9312 pushes back blade holder 22 towards ISP.Therefore, ISP protruding portions 9328 set blade Frame 22 and limits rotation of the blade holder 22 along the direction of arrow 9402 relative to the initial initial position of Cartridge support component 24 Turn and/or can also limit/prevent blade holder 22 and excessively rotated during shaving stroke.

In shown embodiment, ISP protruding portions 9328 can extend outwardly enough from Cartridge support component 24 Distance with engage (for example, being in direct contact) blade holder 22 and prevent blade holder 22 surround pivot axis P A arbitrary further rotation Turn.For example, ISP protruding portions 9328 can be located at pivot axis P A below one or more yoke portions arm 30 inside (for example, Close to yoke portion 47), but as described above, this is not the limitation to the disclosure, unless special requirement are such.Optionally (or it is another Outside), ISP protruding portions 9328 can extend outwardly enough distances to engage (for example, being in direct contact) blade holder from blade holder 22 Supporting member 24 simultaneously prevents blade holder 22 from being further rotated around the arbitrary of pivot axis P A.Therefore, ISP protruding portions 9328 are set Or define 0 position of blade holder 22.Blade holder 22 can rotate in scheduled rotating range around pivot axis P A.Example Such as, predefined rotating range can be as high as 110 degree, be, for example, less than 90 degree or less than 45 degree.Blade holder 22 along with arrow 9402 The rotation in opposite direction (for example, deflection direction) can also be by ISP protruding portions 9328 and/or from blade holder 22 and/or blade Another protruding portion, shoulder, spine and/or the extension (for example, maximum deflection point (MDP) protruding portion) that frame supporting member 24 extends Limitation.The rotation limit on deflection direction is referred to as maximum deflection point (MDP).Therefore, ISP protruding portions 9328 may be used as ISP Both protruding portion and MDP protruding portions.In view of the appropriate adjustment to geometrical constraint around, this embodiment offers relative to The advantages of angle displacement range of the bigger of spring-more than return force is generated in 90 degree.In order to by the quantity of the magnet in component It minimizes, toroidal magnet 9316 is fixed to Cartridge support component 24, and central magnet 9312 is fixed to handle 60.So Afterwards, toroidal magnet 9316 and then it be used to repel and be placed on one or more blade holder magnetic on the rear side 9326 of blade holder 22 Body 9318, thus it is performed simultaneously two functions (for example, head assembly 20 and the connection of handle 60 and biasing of blade holder 22).

Because central magnet 9312 and toroidal magnet 9316 are oriented to their magnetic pole towards identical direction (referring to figure The cross section of assembled unit in 95), so even if when replaceable head assembly 20 is not attached to handle 60 there is also Small return force (for example, pushing blade holder 22 along the direction of arrow 9402), because toroidal magnet 9316 repels in blade holder 22 The back side 9326 on blade holder magnet 9318.However, when mounted, by central magnet 9312 and/or toroidal magnet 9316 It is much greater to combine the power generated, and the power of analog compression spring well, so that blade holder 22 returns to its ISP.

Additional retentivity is can be produced in a variety of ways (to supplement by between central magnet 9312 and toroidal magnet 9316 The power that magnetic brake/connection effect generates), which can be used for so that Cartridge support component 24 and therefore Blade holder 22 is more difficult to unexpected pulling or is detached from handle 60.A kind of possible method for increasing retentivity is included in handle 60 Portion's addition auxiliary annular magnet.Auxiliary magnet can be magnetized by axial direction and by edge and the annular in Cartridge support component 24 The identical direction orientation of magnet 9316, the base portion for being placed on the handlebar 9302 containing central magnet 9312.Thus, when blade holder branch Support component 24 is when being mounted on handle 60, auxiliary magnet will show in Cartridge support component 24 close to toroidal magnet The opposite magnetic pole in 9316 hithermost face, so as to generate pulling force on Cartridge support component 24 and for increasing attachment (during installation) and power (after mounting) is kept.Alternatively possible construction for increasing retentivity is included in support Flexible ring 9330 in component chamber 9304, the internal diameter of the flexible ring are slightly less than the outer diameter of handlebar 9302, when the flexible ring quilt When being completely inserted into supporting member chamber 9304, it is positioned such that a part for 9330 holding handle bar 9302 of flexible ring (such as, but not limited to distal top).In addition (or optionally), one or more lock-in features 9306,9308 can include soft Property receiving receptacle, which engages corresponding lock-in feature on opposite component with receptacle (such as, but not limited to Flexible receive in yoke portion 47 uses receptacle 9308, is engaged by the opposite lock-in feature 9306 being located on handle 60).Hand Protruding portion 9306 in shank 9302 can increase retentivity with the engagement sides of flexible receptacle 9308.This can pass through position In on protruding portion or in receptacle resilient flexibility ring (or the like) realize.These constructions can not increase attachment forces, but It is once these constructions are mounted, the friction generated by the deflection of flexible material can be used as unexpected to Cartridge support component 24 The additional obstruction that ground is disengaged from handle 60, the deflection of the flexible material are caused by the interference with bar top or yoke portion receptacle 's.

The construction that blade holder 22 is made to be back to its ISP is not limited to braking generation by the use of magnetic detent/system of connections The use of magnet.Any one embodiment as described herein can be used, is including but not limited to such as resiliently deformable The mechanical device of pawl (RDP) or other magnetic constructions of the magnetic construction such as, but not limited to shown in Figure 96.For example, one or More arm magnets 9602 can be mounted to one or more (for example, a pair faced each other) in arm 30, and knife Horse 22 can include one or more blade holder magnets 9604, and the axis of one or more blade holder magnets is parallel to The pivot axis P A of the rotation of blade holder 22.Arm magnet 9602 can be attracted to center/intermediate knife horse in blade holder 22 Magnet 9604, this is because their opposite magnetic pole is facing with each other and orients.According to one embodiment, in blade holder 22 Adjacent knife blades frame magnet 9604b, 9604c can be disposed in one or more sides of intermediate knife horse magnet 9604a, with phase With magnetic pole towards arm magnet 9602.Therefore, blade holder 22 tends to rely on the center/intermediate blades coaxial with arm magnet 9602 Frame magnet 9604a, this determines ISP.If blade holder 22 is around pivot axis P A displacements (for example, rotation), due to centering The attraction of centre/intermediate knife horse magnet 9604a and by external blade frame magnet 9604b, 9604c repel combination and undergo resistance Square when blade holder 22 is released, returns to its ISP.For small displacement, this action also simulates the dynamic of spring Make.As shown in Figure 97 generally, displacement is limited to hard stop part/ISP protruding portions 9328.It is dashed forward according to hard stop part ISP Go out the position in portion 9328, one or more external blade frame magnet 9604b, 9604c may be redundancy (if that is, along one The maximum rotation in the direction of a or more external blade frame magnet 9604b, 9604c is very small, then central/intermediate with attractability Blade holder magnet 9604a is compared, and influence can be ignored, and does not need to that blade holder 22 is made to return to its ISP).It should Understand, magnet array arrangement can be used in one or two arm 30.It is also understood that it can be may be programmed with one or more Magnet replace blade holder magnet 9604a to 9604c arrangement, one or more programmable magnets have multiple magnetic poles and/ Or nanostructured magnet, multiple magnetic pole and/or nanostructured magnet, which have, to be programmed to provide various magnetic poles as described herein Multiple regions.In one embodiment, toroidal magnet 9316 can be replaced with magnet array.

Turning now to Figure 98 to Figure 104, describe for couple two components (for example, shave taping knife handle/blade holder and/ Or blade holder yoke portion/blade holder head) two or more radially magnetized (DM) ring-type and/or disc-shaped magnet it is various Embodiment, two of which component are fixed to one another (for example, not detaching) securely, but can be with as defined in certain and limited Mode be moved relative to each other, while tend to return to predetermined at rest position；And it can optionally be applied with enough Power when be manually separated, such as be manually separated during used blade holder is replaced with new blade holder.

With reference to Figure 98 to Figure 100, first embodiment is generally illustrated.For example, Figure 98 is generally illustrated in not The head assembly 20 of assembled state and handle 60, Figure 99 are generally illustrated in ISP everywhere in the head assembly of assembled state 20 With handle 60, Figure 100 is generally illustrated is in the head assembly 20 of inflection point and handle 60 relative to ISP.

Particularly, one or more handle DM magnets 9802 for good and all and regularly couple, are fixed and/or with other sides Formula is installed to the distal end 9804 of handle 60, and one or more Cartridge support component DM magnets 9806 are for good and all and fixed Ground connection is fixed and/or is installed in other ways to a part for Cartridge support component 24 (such as, but not limited to yoke portion 47). In shown embodiment, single handle DM magnets 9802 and single Cartridge support component DM magnets 9806 are shown； It will be appreciated, however, that handle 60 and/or Cartridge support component 24 can include multiple DM magnets 9802,9806.Handle DM magnetic Body 9802, which is also shown in, to be accepted at least partly in handle chamber 9820, and supporting member DM magnets 9806 are shown as The rear mating surface of Cartridge support component 24 is partially extended beyond, it is to be understood that, chamber 9820 can be formed in blade holder In supporting member 24, and therefore the arrangement can overturn.

In addition, handle DM magnets 9802 and Cartridge support component DM magnets 9806 are shown as annular magnet.The ring-type Magnet configurations can help to prevent DM magnets 9802,9806 in its corresponding component (for example, handle 60 and Cartridge support component 24) it is rotated in.For example, the middle section 9808,9810 of DM annular magnets 9802,9806 can have may be coupled to component 60, 24 (such as handle 60 and Cartridge support components 24) and/or with 60,24 overmolded non-circular shape of component, to prevent DM Annular magnet 9802,9806 rotates.It will be appreciated, however, that one or more in these DM magnets 9802,9806 can be There is no the DM disc-shaped magnets of medium pore.DM disc-shaped magnets 9802,9806 can optionally include from DM disc-shaped magnets 9802,9806 In the outwardly extending non-cylindrical bar of one or more planes or offset arm, be also possible to prevent 9802,9806 points of magnet It is not rotated relative to handle 60 and Cartridge support component 24.In addition (or optionally), DM plate-likes or annular magnet 9802,9806 It is a part of can be non-circular (for example, plate-like or ring-type can have generally rectangle or ellipse) to prevent magnet 9802nd, 9806 it is respectively relative to handle 60 and Cartridge support component 24 rotates.

When from the view of Figure 98, handle 60 can be described as with top surface 9801, bottom surface 9803 And right surface 9805 and left surface 9807.Handle DM magnets 9802 can be described as flat with the first plane 9809 and second Face 9811 and the outer circumferential surface 9813 extended between them.Handle DM magnets 9802 can be fixed to handle 60, So that plane 9809,9811 is substantially parallel to the longitudinal axis L of handle, is essentially perpendicular to top surface 9801 and bottom table Face 9803 and it is substantially parallel to right surface 9805 and left surface 9807 is aligned.

DM magnets 9802,9806 are mounted to 60/ Cartridge support component 24 of handle so that when on the replaceable head of installation Component 20 to handle 60 process during make handle 60 and Cartridge support component 24 closer to each other when, DM magnets 9802,9806 Opposite magnetic pole attract and complete attachment procedure.According to one embodiment, DM magnets 9802,9806 are generally tangential each other Ground contacts.The position that will always find out two opposite magnetic poles contacts when DM magnets 9802,9806 are positioned tangent to each other.This A position will be referred to as predetermined at rest position (PRP).In this embodiment, two DM magnets 9802,9806 are installed into and make Obtain makes handle 60 and Cartridge support component 24 are aligned at predetermined at rest position (PRP) as traditional shaving knife.

The distal region 9804 adjacent/close with handle DM magnets 9802 of handle 60 and Cartridge support component 24 with Adjacent/close proximal region 9812 of Cartridge support component DM magnets 9806 can limit 9814 He of handle interface region respectively Supporting member interface area 9816.The shape and profile of interface area 9814,9816 can allow handle 60 and Cartridge support The limited rotation longitudinal movement relative to each other of component 24.DM magnets 9802,9806 will allow this movement to occur, but provide bright Aobvious resistance, so as to simulate the behavior of spring.In fact, 9802,9806 contact point between with them of DM magnets is separate Keep tangent to each other in the entire motion process of magnetic pole movement so that their behavior is similar to the behavior of a pair of of gear (that is, every A DM magnets 9802,9806 not only rotate on the axis of its own, but also around the axis " rotation " of opposite magnet). This displacement is shown in Figure 100, is longitudinal movement in this case (for example, in the longitudinal direction for being substantially parallel to handle 60 Axis L and be essentially perpendicular in the plane that top surface 9801 and bottom surface 9803 extend).Cartridge support component 24 It can be set and/or limit by the profile of interface 9814,9816 relative to the rotation of handle 60 in either direction.

When handle 60 and Cartridge support component 24 are released, DM magnets 9802,9806 make at predetermined at rest position Its own is repositioned relative to each other, and then returns to and/or be pushed to it relative to the original right of handle 60 by blade holder 22 Together.This feature is for being difficult to manually protect Cartridge support component 24 (for example, yoke portion 47) and blade holder 22 by using finger It is useful to hold and reach shaving region in angled forward facing position.According to being applied to Cartridge support component 24 and blade holder 22 power can be easily adjusted angle.

Turning now to Figure 101 to Figure 102, another embodiment using DM magnets is generally illustrated.The arrangement can be with Similar to the embodiment in Figure 98 to Figure 100, but one or more locking magnets 10102 can also be included.Lock magnet 10102 can include but is not limited to DM ring-types or cylindrical magnet 10102.Locking magnet 10102 can be relative to DM handle magnetic Body 9802 is coupled, fixes or is otherwise installed to handle 60 with fixed position and orientation.When being suitably orientated, locking Magnet 10102 has following effect：When 24/ blade holder 22 of Cartridge support component is subjected to being enough to make locking magnet 10102 and knife During the angle displacement that horse supporting member DM magnets 9806 come in close proximity to each other, attract and keep Cartridge support component DM magnets 9806 so that 24/ blade holder 22 of Cartridge support component is maintained at shift position when released, as generally shown in Figure 102 Go out.Due to keeping original predetermined at rest position (PRP) or ISP shown in Figure 101, wherein DM magnets 9802,9806 are with that This adjacent opposite magnetic pole alignment, the result is that there are the selectable two possible positions of user, wherein Cartridge support structure 24/ blade holder 22 of part can be still in its predetermined at rest position, and wherein spring-like backout feature corresponds to small angle displacement (figure 101)；Or it is still in shift position and is securely held in place (Figure 102).

It is alternatively possible to retraction mechanism is set, not to be used for Cartridge support component 24/ in locking magnet 10102 Locking magnet 10102 is retracted into handle 60 when blade holder 22 is fixed on bending/shift position.The retraction mechanism allows in knife 24/ blade holder 22 of horse supporting member hides locking magnet 10102 when being in its predetermined at rest position so that locking magnet will not Negatively affect the feeling and/or collection clast for shaving taping knife handle 60 in the hand of user.Retraction mechanism can include being used for It retracts and locks any arrangement of magnet 10102, such as, but not limited to hand lever, wherein user will need move blade holder Move and third magnet or the gear train using appropriate size disposed before bending position, 24/ blade holder 22 of supporting member from While its predetermined at rest position/ISP is moved to its bending/shift position, which will automatically position and lock magnet 10102。

Although blade holder 22 is shown as only having shaving knife in unilateral side, but it is to be understood that blade holder 22 can be double Side.

Blade holder 22 is with the attachment of Cartridge support component 24 and to blade holder 22 in Cartridge support component 24 The limitation and control of rotation can by it is as described herein it is many in a manner of in any way realize, including but not limited to such as object Manage the mechanical device of axis feature or RDP (pawl being resiliently deformable) or such as replace attraction/repulsive magnets, more magnetic poles or The magnetic arrangement of programmable magnet etc..In shown embodiment, the list that its ISP is determined by a pair of of repulsive magnets is shown Side tool horse 22, a repulsive magnets are located at the back side of blade holder 22, another repulsive magnets is located at Cartridge support component 24/ In the leading edge of the central web in yoke portion 47.However, this limitation not to the disclosure, unless special requirement are such.

In addition, it should be noted that blade holder DM magnets 9806 can be used for generating (for example, repel and/or attract) The magnetic force of blade holder magnet 11410 (see, e.g. the blade holder magnet 11410 in Figure 145 to Figure 147).As a result, in addition to blade Except frame supporting member magnet 11412 or Cartridge support component magnet 11412 is replaced, DM magnets 9806 can be used for producing Magnetisation power.

Turning now to Figure 103 to Figure 105, another embodiment using DM magnets is generally illustrated.It is not as above institute It states with handle DM magnets 9802 and Cartridge support component DM magnets 9806, but one or more arms 30 can include arm DM magnets 10302, and one or more lateral ends 10304 of blade holder 22 can include corresponding blade holder DM magnets 10306.The main function of DM magnets 10302,10306 is to maintain blade holder 22 and is attached to 24/ arm 30 of Cartridge support component, and It is allowed to be upward deflected during shaving stroke, as generally shown in Figure 105.Blade holder DM magnets 10306 can To be exposed to or can be arranged in the interior section of blade holder 22, so as not to be protruded from the lateral ends 10304 of blade holder 22. The ISP of blade holder 22 can be established by the position of the magnetic pole of DM magnets 10302,10306, and will with DM magnets 10302, 10306 opposite magnetic pole angle adjacent to each other occurs.Although DM magnets 10302,10306 are also at it by angular deflection (class Be similar to they make in the above-described embodiment blade holder return to its predetermined at rest position mode) in the case of also partly use In making blade holder head back to its ISP, but the function can also be respectively by Cartridge support component 24 and blade holder 22 A pair of magnets 10308,10310 for mutually repelling perform.In one embodiment, Cartridge support component 24 can keep hand A part for handle 60, and only blade holder 22 can be removed.Optionally, blade holder 22 and Cartridge support component 24 can be with It is considered as component, in which case it is possible to use arbitrary arrangement as described herein is detachable by Cartridge support component 24 Ground is attached to handle 60, and the arbitrary arrangement includes but not limited to, use radially magnetized ring and disk pair improved torsion- Locking-ejection system.

Two or more DM magnets (such as, but not limited to cyclic annular and/or plate-like DM magnets) are available for realizing two components Attachment between (such as, but not limited to shaving taping knife handle 60 and blade holder 22) so that two component fixations firmly with each other, but It is that can be moved relative to each other, while tend to return to predetermined at rest position in a manner of predetermined and limited；It and can be with Be manually separated when being applied with enough power, for example, during new blade holder replaces used blade holder it is manual Ground separates.

With reference to Figure 106 to Figure 108, an embodiment of two or more DM magnets is generally illustrated, this two Or more a DM magnet allow 24/ blade holder 22 of Cartridge support component relative to 60 transverse shifting of handle.Particularly, one or More handles DM magnets 10602 for good and all and regularly couple, fixed and/or otherwise install remote to handle 60 End 9804, and one or more blade frame body supporting member DM magnets 10606 for good and all and regularly couple, are fixed And/or it otherwise installs to a part for Cartridge support component 24 (such as, but not limited to yoke portion 47).Shown In embodiment, single handle DM magnets 10602 and single Cartridge support component DM magnets 10606 are shown；It however, should Understand, handle 60 and/or Cartridge support component 24 can include multiple DM magnets 10602,10606.Cartridge support component DM magnets 10606 are also shown in the Cartridge support structure for being accepted in be formed in Cartridge support component 24 at least partly In part chamber 10620, and handle DM magnets 10602 are shown as partially extending beyond the distal end 9804 of handle 60, but should Work as understanding, chamber 10620 can be formed in handle 60, and therefore the arrangement can be reversed.

In addition, handle DM magnets 10602 and supporting member DM magnets 10606 are shown as annular magnet.The annular magnet Construction can contribute to prevent DM magnets 10602,10606 in its corresponding component (for example, handle 60 and Cartridge support component 24) it is rotated in.For example, the middle section 10608,10610 of DM annular magnets 10602,10606 can have non-circular shape, It can couple and/or overmolded with handle 60, Cartridge support component 24, to prevent DM annular magnets 10602,10606 Rotation.It will be appreciated, however, that one or more in these DM magnets 10602,10606 can be the DM of no medium pore Disc-shaped magnet.DM disc-shaped magnets 10602,10606 can optionally be included from one of DM disc-shaped magnets 10602,10606 or more The outwardly extending non-cylindrical bar of multiple planes or offset arm, are also possible to prevent to rotate.In addition (or optionally), DM plate-likes or The a part of of annular magnet 10602,10606 can be non-circular (for example, plate-like or ring-type can have generally rectangle Or ellipse) to prevent spin-ended turn.

When from the view of Figure 106, handle 60 can be described as with top surface 9801, bottom surface 9803 And right surface 9805 and left surface 9807.Handle DM magnets 10602 can be described as to have the first plane 10609, second Plane 10611 and the outer circumferential surface 10613 extended between them.Handle DM magnets 10602 can be fixed to handle 60 so that plane 10609,10611 is substantially parallel to the longitudinal axis L of handle 60, is essentially perpendicular to right 9805 and of surface Left surface 9807 and it is substantially parallel to top surface 9801 and bottom surface 9803 is aligned.Therefore, Cartridge support component 24/ blade holder 22 corresponds to relative to the transverse movement of handle 60 is being substantially parallel to the longitudinal axis L of handle 60 and big Movement (for example, from side to opposite side) on body in the plane that left surface 9805 and right surface 9807 extend.

DM magnets 10602,10606 are mounted on 60/ Cartridge support component 24 of handle so that when handle 60 and blade When frame supporting member 24 is closer to each other during the process of the replaceable head assembly 20 of installation to handle 60, DM magnets 10602, 10606 opposite magnetic pole attracts and completes attachment procedure.According to one embodiment, DM magnets 10602,10606 are generally Tangential contact each other.It will always find out what two opposing polarities contacted when DM magnets 10602,10606 are positioned tangent to each other Position.This position will be referred to as predetermined at rest position (PRP).In this embodiment, two DM magnets 10602,10606 quilts It is mounted so as at predetermined at rest position, handle 60 and supporting member 24 are with aligned (such as traditional shaving knife).

The distal region 9804 adjacent/close with handle DM magnets 10602 of handle 60 and Cartridge support component 24 The proximal region 9812 adjacent/close with supporting member DM magnets 10606 can limit handle interface region 9814 and knife respectively Horse supporting member interface area 9816.The shape and profile of interface area 9814,9816 can allow handle 60 and blade holder The limited rotation transverse movement of supporting member 24 relative to each other.DM magnets 10602,10606 will allow this movement occurs, But apparent resistance is provided, so as to simulate the behavior of spring.In fact, DM magnets 10602,10606 are between with them Keep tangent to each other in the entire motion process that contact point is moved far from magnetic pole so that their behavior is similar to a pair of of gear Behavior is (that is, each DM magnets 10602,10606 not only rotate on the axis of its own, but also around opposite magnet Axis " rotation ").This displacement is shown in Figure 108, is longitudinal movement in this case (for example, being substantially parallel to The longitudinal axis L of handle 60 and be essentially perpendicular in the plane that top surface 9805 and bottom surface 9807 extend).Blade Frame supporting member 24 can be set and/or limited by the profile of interface 9814,9816 relative to the rotation of handle 60 in either direction System.

When handle 60 and Cartridge support component 24 are released, DM magnets 10602,10606 are at predetermined at rest position Its own is made to reposition relative to each other, and then by head assembly 20 and therefore blade holder 22 is returned and/or is pushed to it Relative to the original alignment of handle 60.

In addition, it should be noted that Cartridge support component DM magnets 10606 can be used for generating (for example, repelling And/or attract) magnetic force of blade holder magnet 11410 (see, e.g. the blade holder magnet 11410 in Figure 147 to Figure 150).By This, other than Cartridge support component magnet 11412 or instead of Cartridge support component magnet 11412, Cartridge support Component DM magnets 10606 can be used for generating magnetic force.

Turning now to Figure 109 to Figure 110, another implementation for being characterized in that two or more DM magnets is generally illustrated Mode.The embodiment is similar to the embodiment described for Figure 106 to Figure 108, still, handle 60 and Cartridge support structure The profile of the interface 9814,9816 of part 24 is configured to not only allow for transverse movement, but also allow Cartridge support component 24/ Blade holder 22 is reversed relative to handle 60 (for example, along arrow 10902 substantially around the longitudinal axis L for being roughly parallel to handle 60 On the direction that shows).Optionally, since one or more protrudent pins 10904 are (such as, but not limited to from Cartridge support component The pin of 24/ yoke portion 47 extension) engagement, twist motion may limit by design, which connect It receives and hole/groove 10906 (for example, on handle 60) and/or is accepted in receiving opening/groove 10906.It should be appreciated that pin 10904 and the arrangement of groove 10906 can convert.Pin 10904 and groove 10906 can be configured to Cartridge support component 24/ blade holder 22 is restricted to be less than 360 ° relative to the torsion of handle 60, is, for example, less than 270 ° or less than 180 °.When with this side Behavior when formula manipulates two DM magnets 10602,10606 is the result that DM magnets 10602,10606 tangentially contact each other.If DM magnets 10602,10606 reverse relative to each other causes their axis is no longer parallel (such as generally to be shown in Figure 110 ), then DM magnets 10602,10606 will tend to return to the position for making axis parallel, because of DM magnets 10602,10606 quilts It is depicted as that there is Maximum Contact area between them, this occurs when axis is parallel.

Turning now to Figure 111 to Figure 113, another implementation for being characterized in that two or more DM magnets is generally illustrated Mode.As being best shown in Figure 111 and Figure 112, one or more handle DM magnets 11102 are by for good and all and fixed Ground connection is fixed and/or is otherwise installed to the distal end 9804 of handle 60, and one or more blade frame bodies support Component DM magnets 11106 for good and all and are regularly coupled, fixed and/or otherwise install to Cartridge support component 24 A part (such as, but not limited to yoke portion 47).DM magnets 11102,11106 can include any size as described herein, shape And/or construction.

In shown embodiment, DM magnets 11102,11106 are aligned so that plane 11109 is (see, e.g. figure 112) it is substantially parallel to the longitudinal axis L (for example, longitudinal axis of collar) of handle 60 and is substantially parallel to handle 60 Top surface 9801 and bottom surface 9803 be aligned.DM magnets 11102,11106 concentrically orient, their magnetic pole is with 180 ° Toward each other.This is because make the predetermined at rest position caused by the power that each pair of opposite magnetic pole attracts each other.It is one or more DM magnets 11102,11106 can be at least partially accommodated in chamber, and one or more DM magnets 11102, 11106 can extend partially outward from a part for its corresponding component (for example, handle 60 and Cartridge support part component 24), It is accepted in the chamber at least partly so that DM magnets 11102,11106 are concentrically aligned.

When 24/ blade holder 22 of Cartridge support component and handle 60 surround the shared axis phase of DM magnets 11102,11106 For it is mutually rotating when, the magnetic pole of DM magnets 11102,11106 is circumferentially separated from each other, so as to when DM magnets 11102,11106 When attempting to make two components (for example, handle 60 and Cartridge support component 24) back to predetermined at rest position, application is caused to be turned round Square.For all low-angle displacements as shown in Figure 113, DM magnets 11102,11106 have to be kept with one heart in entire displacement Trend so that mechanical pivot feature is optional.It is this to influence to reduce, and machine be needed for larger angle displacement Tool pivot.In this case, cyclic annular DM magnets 11102,11106 (opposite with plate-like DM magnets 11102,11106) will provide The advantages of offer physical slot of the mechanical pivot, the mechanical pivot are as axis, pass through two magnets from a component The pin that internal diameter protrudes.Can be with according to whether there is machinery pivot in the attachment of handle 60 and Cartridge support component 24 and disassembly process Feature and change.In the case of no this feature, two DM magnets 11102,11106 can radially or axially each other It is close and final naturally using predetermined at rest position.If there is mechanical pivot feature, then two DM magnets 11102, 11106 may need to be attached to each other by being axially moved.

As it would be appreciated, it can be replaced with one or more programmable magnets (PM) including multiple magnetic pole sections Described in the embodiment or any other embodiment any one or more DM magnet.PM can allow multiple stabilizations Equilbrium position rather than only one position, when common axis rotation of the Cartridge support component 24 around magnet, this will be generated Shift the effect of (indexing) or braking.Therefore Cartridge support component 24 can be placed on any one in several positions A position is to obtain best shaving result.The quantity of possible position and the therefore transformation of magnetic brake system (resolution) maximum quantity of magnetic pole section that can be applied to magnet will be limited solely by.

One optional embodiment is similar to above for the embodiment described in Figure 106 to Figure 108, two of which DM magnetic Body 11402,11406 is tangentially placed；However, in this case, Cartridge support component DM magnets 11406 are restricted to enclose It is rotated around relative to 60 fixed axis of handle, therefore it is no longer rolled around the periphery of handle DM magnets 11402.This is by making With the movement of wherein Cartridge support component 24 be constrained to single plane improved " ball-and-socket " design 11502 come realize ( It is most preferably visible in Figure 114).Disc-shaped or cricoid Cartridge support component DM magnets 11406 are positioned in handle 60 Coordinate in groove portion.Its predetermined at rest position is that two DM magnets 11402,11406 tend to alignment so that its opposite bar to the greatest extent may be used The result being close together to energy.When applying transverse rotation as in Figure 114, user will encounter resistance to movement, And when Cartridge support component 24 is released, since DM magnets 11402,11406 are aligned relative to each other again, blade holder Supporting member 24 will be in its predetermined at rest position relative to handle 60 again.

Show the above embodiment, wherein Cartridge support component 24 will include yoke portion and blade holder 22, the yoke portion and It is (initial to rise that blade holder 22 is assembled such that blade holder 22 can be rotated and returned to known location relative to 47/ arm 30 of yoke portion Beginning position or ISP), but this not limitation to the disclosure, unless special requirement are such.Blade holder 22 and 47/ arm 30 of yoke portion Attachment and rotation to blade holder 22 in 47/ arm 30 of yoke portion limitation and control can by it is as described herein it is many in a manner of In any way realize, the including but not limited to such as machinery of physical axis feature and RDP (pawl being resiliently deformable) Device or the magnetic construction for such as (but not limited to) replacing attraction/repulsive magnets, more magnetic poles or programmable magnet etc..Although Through its ISP is used to show the embodiment by the unilateral blade holder that a pair of of repulsive magnets 11410,11412 determine, one of them Repulsive magnets 11410 are located at the back 11409 of blade holder 22, another repulsive magnets 11412 is located at the central web in yoke portion 47 Leading edge, but this purpose for being merely to illustrate that, and any construction as described herein can be used.It should be noted that It is that repulsive magnets 11412 need not be the individual magnet in component, and are available with handle 60 or Cartridge support component 24 Connection in magnet 11402, one of 11406 come and magnet 11410 in blade holder 22 generates repellency magnetic force.

Turning now to Figure 115 to Figure 118, the ring-type and/or disc-shaped magnet of multipair radial direction magnetized (DM) are described, it is described The attachment that cyclic annular and/or disc-shaped magnet is used to implement between two components (such as, but not limited to shaves taping knife handle 60 and blade holder Supporting member 24) so that two component fixations firmly with each other, but can relative to each other be rotated around a plurality of axis, together When tend to return to predetermined at rest position；And it can be manually separated when being applied with enough power, such as with new Head assembly 20 replace used head assembly 20 during be manually separated.

As described herein, when DM cylindrical magnets are allowed to very close with planar side facing with each other, they will be same It is aligned to axis so that opposite magnetic pole is adjacent.If in addition, a DM magnet from its resting position relative to another DM magnet It rotatably moves, then it will return to its resting position in a manner of simulating the behavior of spring well.

By two pairs or more the uses to DM magnets 11702,11704, Cartridge support component 24 can use first It is (big such as in Figure 116 that DM magnets rotate to (as shown in Figure 115 generally) from first position the second position to 11702 Shown on body), and to 11704, final rotation to the third place (is such as generally shown in Figure 117 using the 2nd DM magnets ).First DM magnets can form yoke portion connector to 11702, and the 2nd DM magnets can form central joint to 11704.

In shown embodiment, yoke portion connector 11706 (see, e.g. Figure 116) is by Cartridge support component 24/ Yoke portion 47 is connected to a part for intermediate knuckle 11708.24/ yoke portion 47 of Cartridge support component and intermediate knuckle 11708 First part respectively include the first DM magnets to one at least one of 11702 DM magnets 11710,11712.DM magnetic Body 11710,11712 tends to keep Cartridge support component 24 and intermediate knuckle 11708 assembled and quiet in making a reservation for Stop bit is put (as shown in Figure 115 generally), but user can be by applying a torque to Cartridge support component 24 And make shared axis phase of the Cartridge support component 24 generally along the direction of arrow 11714 around DM magnets 11710,11712 Intermediate knuckle 11708 is reversed.When release force, DM magnets 11710,11712 are intended to magnetic pole alignment adjacent thereto, This will generate torque, which makes Cartridge support component 24 return to its predetermined rest position relative to intermediate knuckle 11708 It puts.

Central joint 11716 is connected to shaving knife hand including the 2nd DM magnets to 11704, and by intermediate knuckle 11708 Handle 60.The second part and handle 60 of intermediate knuckle 11708 respectively include the 2nd DM magnets at least one in 11704 One in a DM magnets 11718,11720.It should be understood that, it is believed that intermediate knuckle 11708 is a part for handle 60. For example, the part including DM magnets 11720 of intermediate knuckle 11708 and handle 60 can form the of the collar of handle 60 A part 11701 and second part 11703.

As yoke portion connector 11706, DM magnets 11718,11720 holding parts 11701,11703 are assembled and locate In predetermined at rest position (as shown in Figure 115 generally) so that position and tradition of the blade holder 22 relative to handle 60 Shaving knife it is similar.User can 24/ blade holder 22 of rotating knife horse supporting member downward or upward, but due to DM magnets 11718th, 11720 tend to its adjacent magnetic pole alignment, and blade holder 22 will return to its predetermined at rest position upon discharge, User is similar to the resistance to the movement of spring by undergoing.

For both yoke portion connector 11706 and central joint 11716, in the case of given low-angle displacement, DM magnets With keeping concentric trend in entire displacement process so that mechanical pivot feature is optional.For larger angle position It moves, it is this to influence to reduce, and mechanical pivot be used.In this case, DM annular magnets are (relative to DM plate-like magnetic Body) the advantages of physical slot of the mechanical pivot can be provided, which is as axis, is projected through from a component The pin of the internal diameter of two magnets.Will be according to whether there is mechanical pivot feature and become in the attachment of both parts and disassembly procedure Change.In the case of no this feature, two DM magnets can be radially or axially close to each other, and finally adopts naturally Use predetermined at rest position.If there is mechanical pivot feature, then two DM magnets may need attached each other by being axially moved It connects.

Since the DM magnets in two connectors 11706,11716 tend to be presented on predetermined at rest position, if user It is expected shaving knife 10 to be used (for illustration purposes only, to be shown as being similar to be different from the construction of predetermined at rest position The construction of traditional shaving knife), then it can use the mode of locked joints.One possible locking system will include two kinds of shaving moulds Formula：" facial model " and " body pattern ".In facial model, central joint 11716 can be locked in its predetermined rest position It puts, but yoke portion connector 11706 can be allowed to rotate to limited extent.The pattern is shown in Figure 115.Following institute can be passed through It states to use body pattern (for example, as shown in Figure 117 generally)：Two connectors 11706,11716 are rotated by 90 °, So that rotation axis of the Cartridge support component 24 in yoke portion 47 is parallel to handle longitudinal axis L.Because in a state in which DM magnets will attempt to make two connectors 11706,11716 to return to its predetermined at rest position, it is possible to use mechanical lock Two connectors 11706,11716 are maintained at 90 degree of positions.The process changed between facial model and body pattern will be related to Two actions：1) as shown in Figure 117, central joint 11716 is rotated by 90 °；With 2) make yoke portion connector 11706 be rotated by 90 ° ( Shown in Figure 116), obtained construction is shown in Figure 117.The two actions can be carried out according to any one sequence.

With reference to Figure 118, Cartridge support component 24 can include one or more limitation protruding portions 12002, this Or more limitation a protruding portion be at least partially accommodated in knuckle 11708 (for example, part 11701) formed between In one or more restricted rooms or groove 12004.Similarly, handle 60 (for example, part 11703) can include one or more Multiple limitation protruding portions 12006, one or more limitation protruding portions 12006 are at least partially accommodated in formed between In one or more restricted rooms or groove 12008 in knuckle 11708 (for example, part 11701).Certainly, limitation protrudes Portion 12002,12006 and confinement groove 12004,12008 are relative to Cartridge support component 24, intermediate 11708 (part of knuckle 11701) and/or the arrangement of handle 60 (part 11703) can overturn.Limit protruding portion 12002,12006 and confinement groove 12004th, 12008 the movement of yoke portion connector 11706 and central joint 11716 can be restricted to preset range.It is appreciated that It is that predefined range need not be symmetrical about predetermined at rest position.In this way, limitation protruding portion 12002,12006 and confinement groove 12004th, it 2008 permissible be for example rotated by 90 ° in one direction and rotate in mutually opposite directions that (these values are only used for less than 20 degree Illustration purpose).

It should be appreciated that any one DM magnet can be by one or more programmable magnets including multiple pole segments (PM) it replaces.As a result will be multiple stable equilibrium positions rather than only one, this will surround magnet in Cartridge support component 24 Common axis rotation when generate displacement or braking effect.Therefore Cartridge support component 24 can be placed in several positions Any one position to obtain best shaving result.The quantity of possible position and the therefore transformation of magnetic brake system The maximum quantity for the pole segment that can be applied to magnet will be limited solely by.

Show the above embodiment, wherein Cartridge support component 24 will include yoke portion and blade holder 22, the yoke portion It is (initial to be assembled such that blade holder 22 can be rotated and returned to known location relative to 47/ arm 30 of yoke portion with blade holder 22 Initial position or ISP), but this limitation not to the disclosure, unless special requirement are such.Blade holder 22 can be single side Or can be two-sided.Rotation of the blade holder 22 with the attachment of 47/ arm 30 of yoke portion and to blade holder 22 in 47/ arm 30 of yoke portion The limitation and control turned can realize with any way as described herein, including but not limited to such as physical axis feature and RDP The mechanical device of (pawl being resiliently deformable) such as (but not limited to) replaces attraction/repulsive magnets, more magnetic poles or can compile The magnetic construction of journey magnet etc..Such as (but not limited to), blade holder 22 can include two-bay rack head, and ISP is by one-to-many magnetic Pole magnet determines that the rotation axis of the one-to-many pole magnet and blade holder concentrically positions.

As described herein (see, for example, but be not limited to Figure 82), can using more than two magnets come two components it Between generate hovering/floating effect (such as, but not limited to connection) between handle 60 and Cartridge support component 24.Turning now to Figure 119 to Figure 124, an embodiment of shaving knife 10 have at least two concentric radially magnetized magnets 12102, 12104, to realize the floating effect between the two of shaving knife components (such as, but not limited in Cartridge support component 24 and hand Between handle 60), allow two degree of freedom (angle and axial direction) movement.Shaving knife 10, which can also comprise, utilizes DM magnets 12102nd, the repellency magnetic force between 12104 is to realize both locking and pop-up effect between two components.

Particularly, shaving knife 10 includes the radial direction earth magnetism for being attached to a shaving blade insert (such as, but not limited to handle 60) Change the disc-shaped magnet 12102 of (DM), the disc-shaped magnet 12102 is with being attached to another component (such as, but not limited to Cartridge support Component 24) the annular magnet 12104 of radial direction magnetized (DM) be concentrically disposed with, and magnetic pole is arranged such that two DM magnetic The opposing polarities of body 12102,12104 are facing with each other in the internal diameter of cyclic annular DM magnets 12104, and effect is so that Cartridge support The DM magnets 11204 of component 24 and the plate-like DM magnets 12102 of handle 60 are put down at the coplanar point of DM magnets 12102,12104 Weighing apparatus floats or hovers.

According to one embodiment, Cartridge support component 24 (can most preferably may be used including chamber 12502 in Figure 123 A See), and handle 60 can include the bar 12504 extended axially out.Bar 12504 can include plate-like DM magnets 12102, And it can be configured to be at least partially accommodated in the chamber 12502 that can include DM disc-shaped magnets 12102 so that disk Shape DM magnets 12102 can be aligned, so that the opposite magnetic pole of two DM magnets 12102,12104 is in annular DM magnets 12104 ID (for example, floating position) face each other.Chamber 12502 can also be configured to allow for bar 12504 to continue to Forward Dynamic is more than floating position as described herein.Certainly, DM disc-shaped magnets 12102 and DM toroidal magnets 12104 and chamber 12502 It can be overturned with the arrangement of bar 12504, other combinations of DM disc-shaped magnets 12102 and DM toroidal magnets 12104 can also be included.

If there are suitable gaps between Cartridge support component 24 and the mating surface 12506,12508 of handle 60 (most preferably visible in Figure 123 B), then Cartridge support component 24 will appear to axially float relative to handle 60 simultaneously exist Always back to equalization point after deflection, therefore shaving knife 10 is generated between Cartridge support component 24 and handle 60 with small Damper impression.If Cartridge support component 24 is given the small of the shared axis around DM magnets 12102,12104 Axial direction and/or angle displacement (as shown in Figure 120 generally), then the attraction of two DM magnets 12102,12104 will So that Cartridge support component 24 returns to the original angle position at its equalization point (as shown in Figure 119 generally). The attraction of two DM magnets 12102,12104 will make two components return to the axial direction of its original juxtaposed position and/or angle position The range of shifting is referred to as " returning to range ".

Optionally, bar 12504 can include guiding pin 12510 (most preferably visible in Figure 123 A and Figure 123 B), this draws Guide pin is accommodated in the locking being arranged in Cartridge support component 24 and/or pop-up chamber or groove 12512.For example, lock Fixed and/or pop-up chamber or groove 12512 can include allowing pin 12510 is guided to be accepted in opening therein.Once into Locking and/or pop-up chamber or groove 12512 in, guiding pin 12510 (and therefore handle 60 relative to Cartridge support component 24) movement is restricted (for example, by mechanical restriction) to be maintained at the relative motion for returning to two components in range, hereafter In except two kinds of situations providing.

Locking and/or pop-up chamber or groove 12512 can have one or more different regions or range, permit Perhaps it is scheduled to move and/or substantially prevented from 24 phase of (for example, generally fixed, holding and/or locking) Cartridge support component Movement for handle 60.For example, locking and/or an embodiment of pop-up chamber or groove 12512 are generally being schemed It is shown in 123C and Figure 123 D.It is understood that locking and/or pop-up chamber or groove 12512 can surround blade holder branch Support a part for component 24 radially.Figure 123 C are generally illustrated with return range 12514, lock-in range 12516 And/or (it allows pin 12510 is guided to enter and/or exit locking and/or pop-up chamber or groove ejection scope 12518 12512) locking and/or pop-up chamber or groove 12512, and Figure 123 D generally illustrate be arranged on range 12514, 12516th, the guiding pin 12510 at the different location in 12518.Figure 123 E are shown with return range 12514, ejection scope 12518 and/or locking (for example, being locked with 90 degree) and/or the bullet of optional lock-in range 12516 (for example, with 0 degree locking) Go out chamber or groove 12512 and guiding pin 12510.It should be appreciated that although guiding pin 12510 shows in Figure 123 D and Figure 123 E Go out for while be arranged in multiple ranges, but this purpose for being merely to illustrate that, and pin 12510 is guided any given Time will only exist within the scope of one.

In the case of no mechanical constraint, when applying enough angle displacements to Cartridge support component 24, exceed " returning to range " 12514, and DM magnets 12102,12104 start that their mutually exclusive positions are presented.Radially magnetized Plate-like/ring-type in the case of 12102,12104, the effect of this repulsion is to apply to be axially moved so that two DM magnets 12102nd, 12104 no longer keep coplanar.It is this to be axially moved equally possible be happened at equally in the case of no mechanical constraint In either direction.A possible direction being axially moved has the effect for being pulled together two parts, and another has The effect that they are pushed open.If mechanical constraint is added to (for example, guiding pin 12510 and locking and/or pop-up chamber or groove 12512), then can the direction of axial movement occurred when exiting and returning to range be controlled based on user's input.

Turning now to Figure 121, show that shaving knife 10 is in position/alignment as described below：When along a specific direction (example As but be not limited to, in shown embodiment clockwise) rotating knife horse supporting member 24 when, which promotes Two components (for example, Cartridge support component 24 and handle 60) are pulled together.Guiding pin 12510 on handle 60 is (for example, bar 12504) slope in locking and/or the lock-in range 12516 of pop-up chamber or groove 12512 is applied to, makes handle 60 and knife When continuing rotation toward each other, up to the point that gap is closed completely, and each component is relative to that for horse supporting member 24 This is in close contact after being rotated by 90 °.The result is that " locking " or any axial direction of elimination or the floating effect of rotation.Such as Figure 121, It is shown in Figure 123 C to Figure 123 D, locking device can optionally include braking features, and thus Cartridge support component 24 must Handle 60 must be manually pulled away from, to overcome locking and Cartridge support component 24 to be made to be back to quick condition.

Turning now to Figure 122, show that shaving knife 10 is in promoting member (for example, Cartridge support component 24 and handle 60) position/alignment being axially separated from.In this case, (it is such as, but not limited to, in the implementation when along a specific direction In mode counterclockwise) during rotating knife horse supporting member 24, guiding pin 12510 is applied to the slope in ejection scope 12518, pushes away Moving knife horse supporting member 24 and handle 60 are away from each other.Because the interaction of DM magnets 12102,12104, draws if given This feature can be then designed as driving part and is forced point to them by 12510 suitable escape paths of guide pin (escape path) The point opened, causes " to pop up " effect.If the two systems (for example, locking and pop-up) are incorporated into single device, and " locking " and " pop-up " occurs when Cartridge support component 24 is rotated along two different directions, then result such as Figure 123 B and figure Shown in 123D, wherein guiding pin 12510 can reside in three different ranges-return range 12514, lock-in range 12516 or ejection scope 12518.In this case, user can be selected based on him or she relative to 60 rotating knife of handle The direction of horse supporting member 24 assigns the action of Cartridge support component 24.

As described above, Figure 123 E also show an optional locking mechanism, wherein, latched position is floated in angle with nominal Dynamic position is identical.This is wished to be oriented using shaving knife 10 with tradition but is temporarily disabled damper intrinsic in design for user The situation of effect is useful.(for example, " 0 locking ") in this case, by rotating counterclockwise Cartridge support in order Component 24, by its inwardly handle 60 drive, rotate clockwise Cartridge support component 24 until its move and discharge come reality Now lock.In the process, pin 12510 will be guided to lead into latched position 12516 along U-shaped path, this leads to blade holder branch Support component 24 is in starts identical angle with it.Cartridge support component 24 is discharged and will be related to from the latched position 12516 Reverse above-mentioned steps are so that guiding pin 12510 is returned to and returned in range 12514.

Although it is shown that shaving knife 10 has head assembly 20 (including Cartridge support component 24 and blade holder 22), The head assembly has bilateral blade holder 22, and the bilateral blade holder 22 surrounds the pivot being located at its geometric center relative to arm 30 Shaft axis PA pivot, have user may be selected and separate 180 degree two stable equilibrium positions (initial initial position or ), but this not limitation to the disclosure, ISP unless special requirement in this way, and DM magnets (and arbitrary relatively describe Feature) it can be used together with arbitrary blade holder described herein.In addition it is possible to use arbitrary anti-pivot as described herein Realize rotation (and its control), the arbitrary anti-pivot be such as, but not limited to RDP (pawl being resiliently deformable) or Magnetic devices, such as alternately attraction/repulsive magnets (such as selection shown in Figure 119 to Figure 123), more magnetic poles or programmable magnet Deng.

In addition, the arbitrary side of blade holder 22 can include multiple blades angled in same direction (such as face In traditional shaving knife of portion's pattern like that), these blades can on one face and/or in one with even number blade or On more faces, wherein half blade is at an angle of in one direction, the other half blade is at an angle of along another direction (to allow edge For the either direction shaving of body pattern).In this case, user may be found that when blade holder is in quick condition Advantageously using one in two blade holder head positions, and another one is advantageously utilized when blade holder is locked It puts.The system can be further arranged into the second fixed position-" body pattern " (Figure 124).The embodiment can include Optionally there is the handle/shaft ring 12602 of mechanical pivot, it can be from conventional handle position (Figure 119) or facial model and yoke The downward 90 ° of lockings of portion/90 ° of blade holder head assembly latched position (Figure 121).Change between facial model and body pattern Process will be related to two actions：1) collar connector is rotated by 90 ° and 2) as shown in Figure 121 revolves yoke portion connector as shown in Figure 124 It turn 90 degrees, obtained construction is illustrated in Figure 124.The two actions can be carried out according to any one sequence.

As described above, though it is shown that bilateral blade holder 22, but this purpose for being merely to illustrate that, and blade holder can To include unilateral blade holder head.In this case, blade holder head can be along one of close Cartridge support component 24 The axis of longitudinal edge pivots, and is fixed between yoke portion arm 30.It can be with one kind in various ways as described herein To determine unilateral blade holder ISP, including but not limited to magnetic arrangement, such as a pair of repulsive magnets, one of repulsive magnets will Rear side positioned at blade holder head, and another repulsive magnets is positioned across in the leading edge of the web of yoke portion arm.

With reference to Figure 125 to Figure 136, the various embodiments of shaving knife 10 are generally illustrated, the shaving knife 10 includes Magnet is to position and control rotation of the blade holder 22 in Cartridge support component 24 (for example, yoke portion 47).Blade holder 22 can be with It is arranged on the end of the arm 30 in yoke portion 47, and is rotated around relative to 30 fixed pivot axis P A of arm, and can be with Including two stable equilibriums orientation (also referred to as initial initial position or ISP), the two stable equilibriums orientation be separated by 180 degree, by User selects.When the either direction in these directions, such as during shaving stroke, when undergo it is small (<90 Degree) angle displacement when, blade holder 22 can be pushed back to return to its ISP, and passes through magnet and/or the combination generation of ferrous components For traditional blade holder biasing mechanism required torque is completed to generate it.To blade holder 22 in Cartridge support component 24 The limitation and control of rotation can realize with any way that has been described, including but not limited to such as physical axis feature and The mechanical device of RDP (pawl being resiliently deformable) such as replaces attraction/repulsive magnets, more magnetic poles or programmable magnet Deng magnetic arrangement.

Turning now to Figure 125 to Figure 126, a reality of the shaving knife 10 with above-mentioned anti-pivot is generally illustrated Apply mode.As shown, one or more fixed arm magnets 12702 (such as, but not limited to disc-shaped magnet) are positioned at blade holder In one or more in two arms 30 of supporting member 24.Arm magnet 12702 can be relative to pivot axis P A off-axis Ground positions and its orientation is known.Annular magnet radially magnetized in alternate four quadrants between Bei Henan 12704 can be disposed in one or more transverse edges of blade holder 22 and be fixed to one of blade holder 22 or Face on more transverse edges and generally fixed arm magnet 12702.

Due to the off-axis position of arm magnet 12702, arm magnet 12702 has according to adjacent with arm magnet 12702 The quadrant of annular magnet 12704 transfers torque to the ability of blade holder 22.As a result, annular magnet 12704 is oriented such that When one be in two ISP when blade holder 22 is middle, the adjacent each annular magnet of corresponding arm magnet 12702 The polarity of 12704 quadrant is opposite with the polarity of the adjacent surface of disc-shaped magnet 12704.It is pivoted about as a result, being enclosed when blade holder 22 (and nearest) ISP that will be pushed back to that its is immediate of blade holder 22 when axis PA is subjected to small swing offset.

In order to be converted between two possible ISP, user will intentionally make blade holder 22 surround pivot axis P A edges Either direction rotation is until rotation has already passed through 90 degree, there are unstable equilibrium point at the angle, annular magnet 12704 at this time It is adjacent to each other and therefore mutually exclusive with the same pole of fixed arm magnet 12702.Such case is shown in Figure 126.Do not having In the case of having any apparent sources of friction, it is often impossible to blade holder is balanced at one in these unstable equilibrium points 22, therefore blade holder 22 will continue rotation by the point and rest on next ISP naturally, this is a stable equilibrium point, It is separated by 180 degree with ISP before this.It should be noted that the given magnet 12702,12704 with sufficient intensity, this identical Behavior may can by be only located on the side of blade holder 22 and an arm 30 of Cartridge support component 24 in magnet 12702nd, it 12704 obtains rather than by being obtained in the magnet of blade holder 22 and two lateral ends of arm 30, such as generally shows As going out.

Turning now to Figure 127 and Figure 128, another reality of the shaving knife 10 with above-mentioned anti-pivot is generally illustrated Apply mode.As shown, one or more fixed arm magnets 12902 are located in two arms 30 of Cartridge support component 24 It is one or more in, and can have rectangle, ellipse and/or elongated shape.Arm magnet 12902 can be in magnet It is magnetized on thickness (depth).Arm magnet 12902 can be at least partially offset from relative to pivot axis P A axis location and Its orientation is known.Blade holder magnet 12904 can be arranged in one or more transverse edges of blade holder 22 simultaneously And one or more transverse edges fixed to blade holder 22, and it is generally oriented to fixed arm magnet 12902.Blade holder Magnet 12904 can also have rectangle, ellipse and/or elongated shape, however, the length 12906 of blade holder magnet 12904 can With longer than the length 12908 of arm magnet 12902.Blade holder magnet 12904 can be magnetized on the thickness (depth) of magnet.

In this embodiment, magnet 12902,12904 always orients in a manner that opposite magnetic pole is facing with each other, therefore The repulsion property of magnet 12902,12904 is not utilized.The construction is shown in Figure 127.Magnet 12904 in blade holder 22 can be with Centered on pivoting axial direction PA, and it is oriented such that the length 12906 of magnet 12904 is parallel to the width of blade holder 22 12910.Magnet 12904 in 24/ arm 30 of Cartridge support component is shorter and is positioned in behind pivot axis P A and encloses Around pivot axis P A.Pair for causing blade holder 22 that the driving torque of one in two ISP is taken to be derived from magnet 12902,12904 Neat tendency so that matching surface has Maximum overlap region.When applying angle displacement to blade holder 22, due to magnet shape Long axis is no longer aligned, so the overlapping region between magnet 12902,12904 reduces.If angle displacement is small (such as Figure 128 institutes Show), then blade holder 22 will return to immediate (and nearest) ISP in release.As the above embodiment, work as magnet 12902nd, 12904 when being 90 degrees to each other orientation, and there are unstable equilibrium positions.Therefore, if displacement is more than 90 degree, blade holder 22 will be turned to another ISP, this is the stable equilibrium point for being separated by 180 degree with ISP before this.

Turning now to Figure 129, another embodiment party of the shaving knife 10 with above-mentioned anti-pivot is generally illustrated Formula.This embodiment is similar to those embodiments of Figure 125 to Figure 126 and/or Figure 127 to Figure 128, however, magnet can Enhance thermoplastic region with one or more magnetization nanotubes being integrally molded respectively with blade holder 22 and/or arm 30 13102nd, it 13104 substitutes.The purpose that the region 13102,13104 shown in Figure 129 is merely to illustrate.Shown region 13102nd, 13104 may be undetectable or sightless on final end product.These regions 13102,13104 can Be programmed so that opposite magnetic pole across yoke portion arm 30 inner surface and blade holder 22 side surface between gap and each other It faces；Therefore, repulsion is not utilized, and the behavior of blade holder 22 is driven completely by changing the attraction degree between magnetized area It is dynamic.Therefore ISP in the position, overlapping between magnetized area 13102,13104 and is attracted by the location determination of blade holder 22 It is maximum.As the situation of the embodiment of Figure 127 and Figure 128, when give the small swing offset of blade holder 22 (<90 degree) when, The reduction of overlapping area and attraction between two magnetized areas 13102,13104 is for making blade holder 22 most be connect back to it Near (and nearest) ISP.When blade holder 22 is rotated by 90 ° from ISP, it encounters a unstable equilibrium position, and is turned to Another ISP, the ISP are the stable equilibrium points for being separated by 180 degree with ISP before this.

Turning now to Figure 130, another embodiment of the shaving knife 10 with above-mentioned anti-pivot is generally illustrated. The embodiment is similar to the embodiment described in Figure 127 to Figure 128；However, one in blade holder 22 and/or arm 30 or More rectangular magnets can be replaced with ferrous components.In shown embodiment, the blade holder magnetic in blade holder 22 Body 12904 has been replaced by ferrous components 13202, it is to be understood that, arm magnet 12902 can be replaced with ferrous components, and Blade holder magnet 12904 can retain.

Because the embodiment described in Figure 127 to Figure 128 does not utilize repulsion, and the blade holder 22 in Figure 130 Behavior is by the difference when blade holder 22 is rotated around its pivot axis P A between magnetic element 12902 and ferrous components 13202 Attraction level controls, it is possible to replace one group of magnet 12902,12904 with irony item 13202.This can provide cost and Advantage in terms of manufacturability provides similar to the situation of the pairing magnet 12902,12904 shown in Figure 127 to Figure 128 simultaneously Performance.

As described above, the combination of magnet (magnet 12902 or magnet 12904) can be arranged on two arms 30 and blade holder (such as in Figure 131 (as shown in Figure 130 generally) or in the single end of single arm 30 and blade holder 22 in 22 end In generally show).With reference to Figure 132 to Figure 133, thus it is possible to vary the construction of Figure 130 does not include the arm 30 of magnet to remove. In this embodiment, blade holder 22 is constrained and is controlled by an individual yoke portion arm 30, and pivot axis P A is from arm 30 End suspends rather than crosses over the distance between two symmetrical yoke portion arms 30, as generally shown in Figure 131.Knife The pivot axis P A of horse 22 is designed such that blade holder 22 can slide from axis 13502, such as in Figure 133 substantially On show as.In this case, magnetic element (for example, irony item in magnet and blade holder 22 in arm 30 and/or Magnet) it is applied not only to relative to angularly positioning blade rack 22, and blade holder 22 is maintained on arm 30 of arm 30.It replaces Blade holder 22 will be a simple event, i.e., laterally pulled in used blade holder 22 to overcome magnetic resistance, by blade holder 22 Slip away axis 13502 and the upper new blade holder 22 of slip.Due to the magnetism between arm magnet 12902 and ontology ferrous components 13202 Attract, new blade holder 22 will laterally use its appropriate position, and also automatic one used in two ISP.

Showing the shaving knife 10 of Figure 125 to Figure 133 has replaceable replaceable of the user that can be removed from handle 60 Blade holder 22.This can realize with one kind in the various ways that have been described, and the various ways include but unlimited In magnetic construction (such as, but not limited to, the plate-like of matching radial direction magnetized (DM) and/or ring-type or magnetic brake/buckle systems) Or machinery/magnetic construction, such as improved torsion/locking/ejection system.In addition (or optionally), only blade holder 22 can To be replaced, and Cartridge support component 24 can keep for good and all coupling/being attached in handle 60.In such embodiment party In formula, when blade holder 22 is replaced, part or all of Cartridge support component 24 will together retain with handle 60, without It is to be dropped together with blade holder 22.These modifications provide reduce shave materials'use in the displaceable moiety of doctor blade system and The advantages of number of components.

Turning now to Figure 134 to Figure 135, the modification of the embodiment of Figure 130 is generally illustrated.Although in Figure 127 extremely In the embodiment of Figure 128, blade holder 22 is essentially permanently attached to Cartridge support component 24, but Figure 134 to Figure 135 Pivotal axis 13602 be fixed to blade holder 22 rather than arm 30, and be provided in arm 30 and/or magnet 13606 channel/recessed Slot/slot 13604 removes blade holder 22 and axis 13602 with permission from arm 30.In one embodiment, slot 13604 can include Extend through the end of arm 30 and the blind slot of the end at desired rotation axis.Since yoke portion magnet 13606 is present in pivot Also tend to pull in blade holder 22 in arm 30 after shaft axis PA and other than determining ISP until axis 13602 reach it is blind The end of slot 13604, so blade holder 22 can be magnetically maintained in arm 30.Replacement blade holder 22 can be related to edge and leave The direction of handle 60 pulls used blade holder 22 to overcome magnetic resistance, remove blade holder 22 and axis 13602, and by new blade The axis 13602 of frame 22 is slided into slot 13604, as shown in Figure 135 generally.It should be appreciated that the irony in blade holder 22 Element 13202 can be replaced with one or more magnets, and yoke portion magnet 13606 can be replaced with ferrous components.

Turning now to Figure 136, another embodiment of the shaving knife 10 with above-mentioned anti-pivot is generally illustrated. Shaving knife 10 includes with the first part 13802 for being permanently coupled to Cartridge support component 24 and rotatably (or can pivot With turning) it is attached to the two-piece type arm 30 of the second part 13804 of blade holder 22.The first part 13802 of arm 30 includes arm magnet 13806, which has the magnetic pole being aligned with fixed arm magnet 12902, to generate attractability magnetic force, thus by blade holder 22 It is attached to Cartridge support component 24.

It is, for example, possible to use a pair of of mortise and tenon tongue type feature by each yoke portion arm top (for example, second part 13804) it is attached to yoke portion frame (for example, first part 13802).Because yoke portion arm top 13804 has had for blade Frame 22 positions the magnet 12902 (see, for example, the embodiment of Figure 130) of purpose, so these magnets can also be used for yoke portion arm Top 13804 is held in place, if the connection of additional magnet or ferrous components 13806 between frame and top In the yoke portion frame 13802 at place.Removal blade holder 22 will be related to pulling along the direction for leaving handle 60 used in this case Blade holder 22, to overcome magnet 12902 in yoke portion arm top 13804 and the magnet in yoke portion frame 13802 or irony member Attraction between part 13806, and mortise and joint tongue feature is made to slide and separate.It can be by will be on two yoke portions arm top 13804 Mortise and joint tongue feature be aligned with their individual features in yoke portion frame 13802 and allow top 13804 and frame The magnetic attraction between element in 13802 is completed to be attached, so as to install new blade holder 22.The embodiment can include Magnet (if there is two arms 30) in two yoke portion arms 30, not only due to they are used for yoke portion arm top 13804 Fixed to frame 13802, and because they will be helpful to yoke portion arm top 13804 relative to blade holder 22 in same direction Alignment has this to need with suitably and at the same time the mortise and tenon of ground matching on each side during new blade holder 22 is installed Tongue feature.

Turning now to Figure 137, an embodiment of shaving knife 10 is generally illustrated, which can including being attached to Replace nanotube sheets, item or the line 13902 in head assembly 20 (such as, but not limited to blade holder 22).Nanotube sheets, item or line 13902 can warm the skin of user by current electrifying during shaving.From nanotube sheets, item or line 13902 It is warm to be transmitted by IR radiation zones.For example, far infrared radiation (FIR) purely with can by the thermo receptor in human skin perceive The form of heat transmits energy, and almost moment is felt.FIR by user physical experience because mild radiant heat can To penetrate up to 1.5 " below skin.FIR is by absorption of human body and release, therefore the heat that nanotube generates is perceived as nature , and be sensuously potential treatment.Nanotube fibers be successfully immersed in fabric, wrappage and clothes from And FIR is delivered, so as to the benefit that secures good health from its effect.It is important that nanotube sheets, item or line 13902 are not used in heating and shave Any part of scraper 10, and it is only used for the skin of heating user.In this way, shaving knife 10 is likely to feel " cold " (for example, ring Border temperature) thoughts and feelings.

For example, power supply (for example, battery) can be electrically connected on the face of blade holder 22, in face or neighbouring nanometer Section of jurisdiction, item or line 13902, for example, as generally shown in Figure 137.User can be located at shaving by activation Electric switch on knife 10 (for example, handle 60 and/or head assembly 20) heats to control.Battery or other power supply can be located at In some section of shaving knife assembly (for example, handle 60) or outside it, and electric current can be via conducting wire or other electrical connections Flow through nanotube sheets, item or line 13902.Nanotube sheets, item or line 13902 can be applied to arbitrary head described herein Parts 20.

With reference to Figure 137 and Figure 138, another embodiment of anti-pivot and coupling mechanism is generally illustrated.Especially Ground, pivotal axis 14002 (most preferably visible in Figure 138) can include the ferrous material fixed to blade holder 22.U-shaped or fluting Magnet 14004 be installed in the top of yoke portion arm 30, the shape of magnet 14004, which limits, has opening to allow to remove blade The channel of frame 22 (for example, axis 14002).Figure 137 generally illustrates the blade holder for installing/being attached to Cartridge support component 24 22.Channel is illustrated extend through the end of arm 30 and enters magnet 14004, terminates at desired rotation axis measurement Blind slot.Due to the close contact between irony axis 14002 and U-shaped magnet 14004, blade holder 22 is magnetically maintained at arm 30 In, and pivot axis P A is correctly positioned, and axis top is in the end of blind slot.Replacement blade holder 22 is related to edge and leaves The direction of handle 60 pulls used blade holder 22, to overcome magnetic force, removal that irony axis 14002 is attached to magnet 14004 Blade holder 22 and axis 14002, and the axis 14002 of new blade holder 22 is slipped into slot.Irony axis 14002 and fluting magnet Magnetic attraction between 14004 completes assembling process.Optionally, previously described component and ISP mechanisms can be by using The magnet receptacle of programming that programmed magnetic axis (particularly top) is arranged to fluting (there is slot to receive the magnetic of pivotal pin Body) in substitute.Although blade holder 22 and Cartridge support component 24 are shown as with magnetic bias system (see, for example, figure 145 to the magnetic bias system 14702 described in Figure 147), but this limitation not to the disclosure, Unless Otherwise Requested in this way, And shaving knife 10 can include arbitrary anti-pivot described herein.

Turning now to Figure 139 to Figure 140, generally illustrate and be pivotably coupled to blade holder 22 using multiple magnets One embodiment of Cartridge support component 24.As will be explained herein, between blade holder 22 and Cartridge support component 24 Connection can seem to hover relative to Cartridge support component 24 such as blade holder 22.

Particularly, blade holder 22 can be surrounded and be rotated relative to 30 fixed pivot axis P A of yoke portion arm, but for example be existed During shaving stroke, when be subjected to it is small (<90 degree) angle displacement when tend to return to its initial initial position (ISP).In addition, It is expected to complete this behavior in the case of no traditional axis feature so that blade holder 22 is being kept using its pivot axis P A in " hovering " (or seeming to hover) while the heart and in the case of no tradition machinery biasing mechanism.

In order to generate this effect, by it is a pair of it is small, axially magnetized disc-shaped magnet 14206,14208 is relative to one another Installation, a magnet 14206 are fixed to the lateral ends of blade holder 22, and a magnet 14208 is fixed to yoke portion arm 30.These magnetic Body 14206,14208 is located such that they repel each other, and does not have identical magnet pair on the opposite side of blade holder 22 In the case of, they tend to that blade holder 22 is pushed to leave yoke portion arm 30；However, as a pair 14206,14208 on opposite end, Two repulsion cancel out each other and cause blade holder 22 placed in the middle between yoke portion arm 30.

In the case of no additional power, blade holder 22 will not keep coaxial with repulsive magnets, because the position will be One of unstable balance；Blade holder 22 will be forced to be radially separated from Cartridge support component 24.However, around a pair of small Axially magnetized disk 14206,14208 be a pair of larger radially magnetized ring 14202,14204 (in Figure 140 most It is goodly visible).As disk 14206,14208, a ring 14204 is fixed to blade holder 22, and another ring 14202 is consolidated Surely yoke portion arm 30 is arrived.However, these rings 14202,14204 are oriented such that when blade holder 22 is in its ISP, ring 14202, 14204 opposite magnetic pole is adjacent to each other so that they attract.The radially this arrangement (face of magnetized ring 14202,14204 Opposite stacks) there is the trend for keeping mutually coaxially positioning.Exactly this power counteract by this to the disk 14206 of repulsion, 14208 radial loads applied, and blade holder 22 is made to be located on pivot axis P A in yoke portion arm 30.In addition, even if It is opposite to have around in the case that their common axis line is subjected to limited rotation amount, being located adjacent to relative to each other The radially magnetized rings 14202,14204 of two of magnetic pole stackings also keep concentrically positioning, in this case, magnet 14202nd, 14204 tend to be rotated back to upon discharge their the adjacent preferred juxtaposed position of opposite magnetic pole.As described above, just It is that this feature results in desired biasing behavior.Therefore, times of internal axially magnetized disc-shaped magnet 14206,14208 Business is to generate hovering effect, and the task of external radially magnetized annular magnet 14202,14204 is to maintain blade holder 22 It is located on pivot axis P A, and is allowed to when it is by small swing offset back to its ISP.

This change is to replace radially magnetized ring 14202,14204 with reference to more magnetic poles or the magnet ring of programming.With diameter As magnetized ring 14202,14204, these magnets will be positioned so that their opposite magnetic pole is adjacent to each other, but It is that each magnet will be there are two above magnetic pole.This will lead to that there are multiple ISP or stable equilibrium positions.The one of such case A special case is using four pole rings, causes two ISP points to open 180 degree.The embodiment particularly suitable for bilateral blade holder head Portion 22 is used together, and user can be arbitrarily located at one in two possible ISP.

According to arbitrary embodiment described here, blade holder 22 can be together replaced with Cartridge support component 24；So And, it is also possible to, only blade holder 22 can be removed, and Cartridge support component 24 can be integral with handle 60.

With reference to Figure 141, repellency disc-shaped magnet 14206,14208 can optionally include mating feature, such as but unlimited Protrusion 14304 on the recess portion 14302 on the magnet positioned along pivot axis P A and another magnet.Protrusion 14304 It can be configured to be accepted at least partly in recess portion 14302 to introduce additional control element, because blade holder 22 can To be allowed to move radially on a small quantity relative to what pivot axis P A was carried out, but can not thoroughly be disengaged.In this case, Cartridge support component 24 and blade holder 22 may be constructed such that pe pinanent assemblies, and can use blade holder branch as described above Support the attachment mechanism between component 24 and handle 60.

Turning now to Figure 142 to Figure 144, generally illustrating can be selectively with " facial model " or " body pattern " Another embodiment of the shaving knife 10 of arrangement.Under facial model, it is contemplated that in a top view, blade holder 22 will Perpendicular to handle 60, and will there is ideal start angle relative to the plane of the skin surface of non-zero.Under body pattern, It is contemplated that in a top view, blade holder 22 will be parallel to handle 60, and it is preferably also the plane for being parallel to skin surface Positioning.As described herein, shaving knife 10 includes composite curvature track 14402, to generate blade holder 22 relative to the more of handle 60 A position (for example, facial model and body pattern) and based on blade holder 22 be in facial model or body pattern position and from It is dynamic to change blade holder head ISP (initial initial position).Therefore, composite curvature track 14402 not only repositions blade holder 22 Relative to the alignment of handle 60, but also change ISP automatically as blade holder 22 relative to redirect one of handle 60 Point.
