Technical field

Safety razor is shaved the present invention relates to wet, and more particularly relates to having for shaving another person's face and is pacified It is attached to the razor system for meeting the razor cartridge for being ergonomically shaped shank.

Background technique

In general, there is at least one to have the blade of cutting edge, the knife for the blade holder of safety razor or blade unit Horse or blade unit are moved on shaved skin surface by means of the shank that blade holder is attached to it.Some razor settings There is the blade holder of spring biasing, which pivots relative to shank to follow the profile of skin during shaving.It can be by blade Frame is removably mounted on shank to allow when blade sharpness has declined to unsatisfactory level with new knife Horse replaces old blade holder, or if it is desired to abandons entire razor in one or more blade rusts Words, can be permanently attached to shank for it.

Razor blade assembly is disclosed, and the skin that wherein cutting edge portion of blade members is maintained at razor blade assembly connects It closes between surface (commonly referred to as protector) and top cover.During shaving stroke, protector contacts one or more blade members The skin of front, and top cover contacts the subsequent skin of one or more blade members.Top cover and protector can help to establish So-called " shaving geometry ", that is, determine parameter of the blade during shaving relative to the orientation of skin and position, the orientation Then there is strong influence on shaving performance and razor effect with position.Top cover may include the shaving aid of available water logging out to subtract Few resistance simultaneously improves comfort level.Protector can be generally rigid, such as provide the frame or platform structure of support with for blade It is integrally formed.Protector also may include relatively soft elastomeric material to improve skin stretch.

Personal nursing personnel usually nurse due to intelligence and/or physical strength reduce and can not oneself shaving individual, the intelligence And/or physical strength reduction is usually caused by chronic aging, damage or various degenerative diseases.The task of shaving another person needs pole It is careful, patient, coordinate and spatial perception is to avoid hurting shaved people.In the U.S., hairdresser secures permission, and usually With other people experience of many years shaving.However, intimate kinsfolk and care-giving professional are to for shaving another person Shaving technology be not familiar with.In addition, hairdresser is usually using straight sword razor, this exists for personal nursing personnel or kinsfolk Do not attempted with another person in the case where without suitably training using will be breakneck.To wet safety razors shaving system System is enhanced more than 100 years, self is applied to realize.However, these designs are time for shaving another person Excellent.

Therefore, it is necessary to a kind of shanks for meeting ergonomics that is mounted to allow suitable control and manipulation to shaving The razor cartridge of another person's face.

Specific embodiment

When oneself shaving, razor handle is maintained between 30 degree usually in the form of downward stroke or upward stroke and The angle being parallel between the position of shaved skin surface.This arrangement is generally comfortable and intuitive for user , and good visuality is also provided when the shaving before mirror.Hand and shaving surface are kept into distance good, this Mean the hand masking of the not shaved person oneself in the reflection visual field in shaved region.Such case forms design and optimization razor Mode more than 100 years.However, the positional relationship compared with from shaving, between razor handle and shaved people (object) It is very different.

Referring to Figure 1A and 1B, show by the side view of the human face of another person's shaving.Razor cartridge 10 can be pacified It is attached to the end of razor handle 12, which has elongated grip portion 14, which has longitudinal axis 16.Razor cartridge 10 can limit shaving plane 18.It is typically no longer valid from shaving model in shaving another person, because It will cause some problem for it.In shaving another person, shaved individual's (that is, object) is generally in seat or position of lying, and The people (that is, nursing staff) for executing shaving function stands.The relative position of nursing staff and object generates relatively low face And neck location, this to become difficult much simultaneously using conventional grasp with stroke positioning razor cartridge 10 (as shown in Figure 1A) And it is uncomfortable, shown in the wrist angle " α " such as by exaggeration.Hand can be substantially parallel to shank axis 16, thus by wrist phase Substantial transverse position is placed in for hand.

Other levers can be used, as shown in Figure 1B.For example, shank 14 can be with higher razor handle angle close to object Face, the angle are closer to that shaved skin can be approximately perpendicular to.Wrist angle can produce more neutral position, this may Generate the more comfortable position for nursing staff.However, the position also leads to blade and skin differential seat angle, so as to cause shaving It is poor to scrape performance (for example, efficiency and safety).For example, shaving plane 18 will not conform to shaved skin surface well. In addition, blade holder 10 may prematurely be switched to complete pivot position when blade holder 10 is placed on skin.Therefore, very Weakened in big degree pivot blade holder skin is conformal and safety benefits.

Current razor handle design is nor optimal, because the relatively low position of object causes nursing staff must not It does not bend over object to improve the visuality and contact for the treatment of shaving region.In this case, face and neck have many It is significantly more difficult to the region of shaving, such as, the region that the downside of lower jaw and neck and lower jaw are met.When shaving physical strength or intelligence subtract When the someone moved back, the head of object is generally impossible to lift or rotate.Hairdresser can usually be lain by being sitting in its object This is solved the problems, such as on the chair of sleeping, rotation and change height to realize best body arrangement.When at home or in nursing staff Facility on shaving someone when, this is usually infeasible.In addition, for many intelligence reduce Male Nurses and Speech, sits quietly motionless often impossible during shaving process.Uncertain movement brings serious security risk, and Shaving object is set to become significantly to have more challenge.

Referring to fig. 2, the cross-sectional view of common T shape twolip safety razor 20 is shown.Top cover 22 and protector 24 can establish with Top cover 22 and the tangent shaving plane 26 of protector 24.Blade 28 with cutting edge 30 can be positioned in shaving plane 26.Peace Full razor 20 can have shank 32, which has central longitudinal axis 34.Central longitudinal axis is relative to 26 He of shaving plane The position of shaving plane 26 establishes during shaving stroke safety razor 20 must be how close to skin.For example, shaving plane 22 can be about 135 degree angle " β " intersect with the central longitudinal axis 34 of shank 32.As explained in more detail below, not by Theoretical constraint, it is believed that the shaving plane of razor and the intersection of central longitudinal axis should be closer to vertically with another for shaving Personal (that is, third party's shaving).

Referring to Fig. 3, the perspective view of razor system 40 is shown.Razor cartridge 42 can be mounted to shank 44.Certain In embodiment, shank 44 can be substantially straight.Razor cartridge 42 can be removeably or permanently installed to shank 44. For example, razor cartridge 40 can be removably mounted on shank 44 to allow to have declined in blade sharpness to not making us Old razor cartridge 42 is replaced with new razor cartridge 42 when satisfied level, or if it is desired in one or more Blade rust when by entire razor abandon if, it can be permanently attached to shank 44.It, may for third party's shaving Advantageously having can be removed blade holder 42, this can be removed blade holder and can separately be discarded in shank 44 in sharp instrument box to reduce and give up The cost that object removes.For hygienic purpose, blade holder 42 can be abandoned after each shaving.Blade holder 42 can be installed to has The connector 46 of thumb pad 48, to be conducive to being suitably oriented for user's hand.Thumb pad 46 can limit opening 50.In certain embodiment party In case, opening 50 may extend entirely through connector 46.One end of connector 46 can have for being attached blade holder 42 Docking mechanism 52 (for example, a pair of pin).

A referring to fig. 4 shows the side view side view by another person with the human face of 40 shaving of razor system.In addition, Fig. 4 B shows the viewgraph of cross-section substantially along the line 4B-4B of Fig. 3 razor system 40 intercepted.The shaving direction of razor system 40 It is indicated by arrow " A ".Razor cartridge 42 can have the blade between protector 54, top cover 56 and protector 54 and top cover 56 58.Blade 58 can have cutting edge 55.Razor cartridge 42 can have neutral position (such as resting position), wherein shaving plane 60 in seven degree perpendicular to the central longitudinal axis 66 of shank 44, and more preferably in five degree.For example, in certain implementations In scheme, shaving plane 60 can about 85 degree to about 95 degree (that is, in vertical 5 degree) angle " euro " and shank 44 center Longitudinal axis 66 intersects.Without being bound by theory it is believed that the phase of the central longitudinal axis 66 of shaving plane 60 and razor handle 44 Handing over should be closer to vertical (that is, 90 degree) to be used for shaving another person (that is, third party's shaving), so as to improve the people of user Razor cartridge 42 is simultaneously appropriately positioned on the skin of shaved people by body engineering science.Shaving plane 60 is relative to shank 44 Central longitudinal axis 66 position be conducive to against when shaving skin surface press razor cartridge 42 when nursing staff The neutral and more intuitive position of hand.In addition, the relative position of shaving plane 60 and central longitudinal axis 66 allows razor knife Horse 42 pivots in its entire moving range, to be conducive to the wheel that razor cartridge 42 follows skin during shaving stroke It is wide.In certain embodiments, central longitudinal axis 66 may pass through the pivot axis 68 of razor cartridge 42.

The positioning of 48 position of thumb pad can also give the bigger control of nursing staff and response is felt.For example, thumb pad 48 is advantageous Shaving plane 60 and the position on the direction of razor cartridge 42 are directed toward in the finger of user.Thumb pad 48 can have spill top Portion surface 70, the concave top surface have leading edge 72, which is oriented away from shaving plane 60 and central longitudinal axis 66 Intersection point about 3mm to about 20mm, and preferably 5mm to about 15mm.The center that thumb pad 48 can be substantially parallel to shank 44 is longitudinal Axis 66 and transverse to shaving plane 60.Therefore, the bottom surface of finger towards central longitudinal axis 66 and can be directed toward shaving Plane 60.

Referring to Fig. 5 A, 5B and 5C, during the schematic diagram of the razor system 40 with razor cartridge 42 is respectively indicated as being in Property, forwardly and rearwardly pivot position.In certain embodiments, in neutrality, forward or backward pivot position, central longitudinal axis 66 can wear between the point on the point and the protector 54 tangent with shaving plane 60 on the tangent top cover 56 of shaving plane 60 It crosses.Central longitudinal axis 66 can be flat with shaving at the cutting edge very close to blade (for example, between protector and top cover) Intersect in face 60.For example, central longitudinal axis 66 can be less than at the horizontal distance d1 of 25mm and shaving plane 60 away from cutting edge 55 Intersection.In certain embodiments, central longitudinal axis 66 can at away from the about 0mm to about 20mm of cutting edge 55 with shaving plane 60 Intersection.As 42 blade holder of razor pivots, the position that central longitudinal axis 66 intersects with shaving plane 60 is changeable.For example, shaving Knife blade holder 42 is pivotably to about 18.5 degree of pivot position forward, so as to cause central longitudinal axis 66 and shaving plane 60 Intersection is located closer to top cover movement.When razor cartridge 42 is switched to about 18.5 degree of pivot position backward, center It the position that longitudinal axis 66 intersects with shaving plane 60 can be mobile (Fig. 5 C) closer to top cover 56.In certain embodiments, when When razor cartridge 42 is pivoted from forward facing position and rearward position, the intersection point of central longitudinal axis 66 and shaving plane 60 can be kept Between top cover 56 and protector 54, to provide improved control for user.Razor cartridge 42 can have and neutral pivot Indexing is set to 25 degree of final pivot position forward, wherein preferred final pivot position forward with neutral pivot position at In 20 degree (that is, 0 degree to 20 degree).Razor cartridge 42 can have pivots position at 25 degree final with neutral pivot position backward Set, wherein preferred final pivot position backward with neutral pivot position at (that is, 0 degree to 20 degree) in 20 degree.

Central longitudinal axis 66 may pass through blade 58.In certain embodiments, central longitudinal axis 66 can be positioned so that In neutrality or cutting edge 55 about 0mm to about 20mm of the position away from blade 58 is fixed, and more preferably about 0mm to about 10mm, And the even more preferably horizontal distance " d1 of about 0mm to about 2mm.Central longitudinal axis 66 can be positioned so that pivot forwardly Indexing is set away from the about 0mm of cutting edge 55 to about 20mm, and more preferably about 0mm to about 10mm, and even more preferably about 0mm To the distance " d2 " of about 2mm.Central longitudinal axis 66 can be positioned so that in pivot position backward away from the about 0mm of cutting edge 55 to about 20mm, and more preferably about 0mm to about 10mm, and the even more preferably distance " d3 " of about 0mm to about 2mm.Certain In embodiment, central longitudinal axis 66 may pass through pivot axis 68.

It should be appreciated that and not all razor or razor handle all will be full symmetric.It therefore, can be for any shape Razor handle calculates central longitudinal axis.Referring to Fig. 6 A and 6B, the side view of the razor system 40 of Fig. 3 is shown on grid.It shaves The side profile of knife system 40 may be derived from photo, orthogonal computer Computer Aided Design (CAD) or razor system 40 can be scanned or It is painted on grid.Grid can have X-axis and Y-axis, have interval rule unit identical with ratio.For example, Fig. 6 A is shown Every 10 units have both X-axis and Y-axis of grid lines.Coordinate is along the upper profile 74 and bottom profiled 76 of shank between rule Every drafting.The distal end 78 of first contact point 80 between shank 44 and blade holder 42, for shank upper profile and under Profile should draw minimum ten points with regular spaced interval.For example, whenever taking coordinate in the bottom profiled in shank, just Corresponding point is taken in the upper profile of shank.The software package of such as Microsoft Excel can be used for limiting central longitudinal axis Linear trend 82 is drawn between 66 point.Alternatively, least squares method can be used for calculating by shank profile coordinate ' best Fit line '.The line of best fit limits central longitudinal axis.The calculating of least squares method is as follows.

Step 1: calculating the average value of X value and the average value of y value.

Step 2: following formula gives the slope of line of best fit:

Step 3: the y-intercept of line is calculated by using following formula:
