18 Claims, 6 Drawing Figures minimum: m4 3Q8l1188 sum 2 or z 1 SHAVER WITH REMOVABLE HEAD This invention relates to the field of electric dry shavers, and, particularly, to shavers having a detachable shaving head.
It is highly desirable to provide means for detaching the shaving head of an electric shaver for the purpose of brushing hair clippings out of the cutter assembly. Hair clippings are normally deposited within the shaving head, and would accumulate unless so removed. It would be highly desirable to provide a detachable head which is especially suitable for a ladys shaver, and which can be readily manipulated by someone with little mechanical skill, and with a minimum of likelihood that the shaver or the shaving head assembly would be damaged in the process, or that it would be reassembled improperly.
It is more likely that cleaning the cutter assembly will become part of the users routine, if the manipulation steps involved are simple, almost instantaneously accomplished, and virtually error-proof. Hence, it is desirable to provide a shaver having these features.
Shaving heads in electric shavers are operatively connected to an electric motor, typically through a vigorously oscillating driving arm. Consequently, even though it is desirable that the head be easily and conveniently detached and easily re-attached to the shaver, it is imperative that the head be attached so as to withstand the vigorous mechanical action and vibration, as well as to withstand the dislodging forces which are encountered in normal use.
Furthermore, the manufacture and sale of electric shavers is a highly competitive business, and it is imperative that such shavers, including the shaving head retention and release features, be simple and economical to manufacture.
In addition, an electric shaver which is intended for use as a ladys shaver must be readily and safely adaptable for shaving angular surfaces and recessed regions, such as, for example, shaving legs, armpits, and the like, as well as lend itself to good styling features.
It is an object of the present invention to provide an electric shaver having a pop-out shaving head which can be simply and almost instantaneously removed from the shaver by the user, and which can be replaced as easily.
It is a further object of the present invention to provide a shaver in which the shaving head can be conveniently and simply removed from the shaver by a person with little mechanical skill for the purpose of cleaning, and in which the shaving head assembly can be reassembled by the user and re-attached to the shaver with virtually no likelihood of errors in re-assembly or re-attachment.
It is another object of the present invention to provide a shaver in which the cutter assembly can be removed from the shaving head and replaced from time to time by a person with a low leval of manual skill and with no special tools.
It is a further object of the present invention to provide a shaver which can be manufactured in a relatively simple manufacturing and assembly operation, and, which, because of the simplicity of the structures and the assembly sequence involved, can be manufactured economically.
It is another object of the present invention to provide a shaver which readily lends itself to a good styling feature, whereby the shaver, although utilizing a detachable' head, presents a well-contoured, free-flowing unitary appearance.
1 These and other objects which will be apparant hereinafter are all achieved in accordance with the present of being removed from the shaver shown in FIGS. 1 and i FIG. 4 is a cross-sectional view taken approximately along the line 44 of FIG. 2.
FIG. 5 is an end view of the shaver shown in FIG. 1.
FIG. 6 is a cross-sectional view taken approximately along the line 66 of FIG. 2 taken through the shaving head and a portion of the driving arm.
Referring now to the accompanying drawings, an electric ladys shaver is generally indicated by the numeral l0, and includes a body or housing generally indicated by the numeral 12 comprising a handle portion l4 and head portion 16. Head portion 16 houses and supports the shaving head assembly generally indicated by the numeral 18 and the lighting assembly generally indicated by the numeral 20.
ShaverlO includes an electric motor 22, transmission means 24 including an eccentric 25 for converting the rotary drive of motor 22 to the oscillating drive of driving arm 26 which operates shaving head 18. Conventional electrical cord plug-in means (not shown because conventional) are provided at the base 28 of handle l4 and an omoff switch 30 controls the operation of the shaver 10.
Shaving head assembly 18 is mounted within upwardly facing recess 32. The recess 32 is defined by up- I wardly projecting side wall 34, a central wall 36 which is'parallel to side wall 34, and end walls 38, 40. Central wall 36 divides recess 32 fromlighting assembly 20. Housing 12 isformed by a pair of cup-shaped members 42, 44 which are formed with opposing halves of side walls 34, 36 which abut in a common plane to form side walls 34, 36. Generally speaking, members 42, 44 are mirror images, and it is apparent that switch 30 and motor 22 reside within hollow handle portion 14 formed by butting housing members 42, 44.
End walls 38, 40 are integral'extensions of members 42, 44 respectively. The bottom of recess 32 is defined by a wall 48 which is made of portions of housing members 42, 44 which extend inwardly in a common plane.
Central opening 50 extends through bottom wall 48 and motor drive arm 26 extends therethrough, as shown in FIGS. 2 and 3. A heavy C clip 52 having a flat bridging portion 54 extending between members 42, 44 helps to maintain these members 42, 44 in proper butting position, and includes end hooking fingers 56, 58 extending downwardly into recesses 60, 62 in housing portions 42, 44, respectively, to engage and secure these portions.
Shaving head 18 is retained in recess 32 by a resilient detent, generally 66. Detent 66 includes a flat base portion 68 which extends across housing members 42, 44 and includes end tab portions 70, 72 which reside in respective recesses 74, 76 in housing members 42, 44, re-
l spectively. It is noted that at least some gap exists between end 70, 72 and the adjacent walls of recesses 74, 76, respectively. (See FIGS. 4 and 5).
It is also noted that, due to the usual manufacturing tolerances, some gap also exists between the sides of ends 70, 72 and opposing portions of housing 42, 44 with the result that some play or movement of detent 66, both laterally and longitudinally along the elongated dimensions is possible. Moreover, some slight angular rotation with respect to a plane passing perpendicularly through the center of base 68, for example, is also possible.
Detent 66 also provides a central opening 78 through which drive arm 26 passes and in which drive arm 26 oscillates. Detent 66 also includes two pair 80, 82 of opposing resilient members of latching detents 8484. It is noted that detent 66 is elongated, and that resilient members 84-84 are located near the respective ends 70, 72 of detent 66. As shown in FIGS. 2 and 3, detent 66 consists of spring stock which has been formed to include the laterally extending projections 84-84 which initially smoothly curve upwardly and reverse direction towards the direction of body portion 68, and then, smoothly curve upwardly again and'reverse direction again to the direction generally away from body portion 68. It is the latter curved latching portions FIG. 2 shows that latch portions 86 not only assist in the proper aligning of head 18 along its long dimension, but, moreover, assists in drawing head 18 inwardly with respect to recess 32 to bring the sides 90, 92 which are smoothly curving, to rest against respective opposing and confining sides 94, 96 which constitute part of walls 34, 36. Moreover, in accordance with an important aspect of the present invention, head 18 is dimensioned so that ends 98, 100 thereof, fit snugly between end walls 38, 40. (See FIG. 4). Partly as a result of these structural relationships, cutter head 18 is very securely retained in recess 32 with substantially no motion during operation.
A shaving head ejector is generally indicated by the numeral 104 and includes an external finger gripping portion 106 and a pair of laterally extending lugs 108-108 which are retained in recess 109-109 in housing members '42, 44. Recesses 109, 109 are elongated and ejector 104 can move in the direction along the long dimension of the shaver handle to the extreme positions illustrated in FIGS. 2 and 3.
The shaving head assembly which is generally indicated by the numeral 18 comprises an integral molded plastic base 110, an outer cutter 112 which is received in a slot 114 in base 110, an inner cutter assembly 116, hair-raising brushes 1 18- 118 disposed at both sides of outer cutter 112, and facing elements 120-120.
Brushes 118-118 are made of tufts 119 bonded into base 110, and mid-portion 121 of facing plate resembles a plurality of fingers which are spacedapart from block 110, extending laterally to help maintain tufts 119 in desired perpendicular relationship with respect to base 110.
From a consideration of the drawings, it will be appreciated that cutter assembly 18 is bilaterally symmetrical with respect to a middle cross-sectional plane extending transversely across the narrow dimension, and also is bilaterally symmetrical with respect to a middle cross-sectional plane extending through the long dimension of cutter assembly 18.
Referring now to FIGS. 2 and 6, outer cutter assembly 112 includes a plurality of rows 122 of cutters, and inwardly directed side portions 124 which are bonded at the rearward extreme to the outside of an inner U shaped bridging element 126. Outer cutter 112 is shaped from flat stock with elongated U-shaped recessed 113 extending between rows 122 of cutters. It is apparant from a consideration of FIG. 6 that bridging element 126 extends the entire length of outer cutter 112, and that the bottom portion 128 of bridging portion 126 includes a central opening 128 through which driving arm 26 passes, as 'well as a plurality of other openings which provide bridging bands 131 around which retaining bosses 134, 136 at the bottom of recess 114 in base 110 are snugly received, to fix outer cutter 112 with respect to base 110. The bottom portion 128 of outer cutter 112 presses against the bottom 138 of slot 1 14 and the sidewalls of slot 114 snugly rearwardly extending portions of sidewalls 124 to provide excellent stability characteristics. Inner cutter assembly 116 comprises a movable cutter 140 and a spring drive arm coupling element 142. The outer configuration of inner cutter 140 is adapted to mate with the inner configuration of outter cutter 112.
Inner cutter 146 includes a plurality of rows 143 of I cutter blades and is shaped to include recessed regions 144 therebelow. Recessed regions 144 of inner cutters receive recessed regions 123 to maintain alignment between respective rows 122 and 143 of inner and outer cutters. f
It is noted that when viewed from the underside of cutter 140 the central row 146 of inner cutter 140 appears as a recess and it is apparant from a consideration of FIGS. 2 and 6 that drive arm 26 extends into the region defined by the central row 1460f the inner cutter 140. End 148 of drive arm 26 is received in a U- shaped detent 149 in spring 142. Spring 142 also includes lateral arm portions 150, 152 having bridging detents 154 at each end which include clips 156 which pass through openings 158 in inner cutter 140. Inner cutter assembly 116 can move easily within cutter l 12. Tensioning of spring 142 by insertion of end 148 into detent 149 uniformly urges cutting faces of cutter 140 against opposing operating surfaces on cutter 112.
The underside of the plastic block or base 110 includes two pairs of opposing recesses 160, 162 defined by undercut latching surfaces 164-164 which engage the latching portions 86-86 of detent 66.
The underside of block 110 also includes a plurality of openings 168-168 through which a small pushing tool (not shown) can be brought to bear against the bottom 128 of bridge element 126 of outer cutter 1 12. This makes it possible to replace a set of outer cutters 112 and inner cutters 116 without necessitating the purchase of a new base element 1 l0, and structures associated therewith. Hence, to remove cutter 112 from head 18, head 18 is first removed as for cleaning and cutter 112 is snapped out of slot 114, for example, by pressing the point of a pencil through openings 168-168 against bottom 128.
FIG. 3 shows the cutter head 18 in a moved position,
that is, in that position which is obtained during the ejection of head assembly 18 from recess 32 as for cleaning. As indicated above, the ejection mechanism, generally 104, can move to several positions in a direction corresponding to the lengthwise direction of handle portion 14. During ejection, surface 94 of ejector 104 bears under rounded side 90 of head 110 and urges shaving head 110 to pivot. Because of the mating configuration between the latching portions 164 of head base 110 and springlatching portions 86 of detent 66, and because of the close proximity of lateral surface 90 of head 110, and opposing surface 96 of recess 32, shaving head 18 pivots as indicated in F IG. 3. The pivot axis is substantially parallel to the direction of the elongated dimensions of head 18, that is, perpendicular to ends 38, 40. Shaving head 18 can be completely removed from recess 32 to permit cleaning or replacement.
It will also be appreciated that shaving head 18 is bilaterally symmetrical with respect to both transverse and longitudinal mid-sectional planes, and, consequently, there is no right or wrong way in which to orient, end for end, the shaving head 18 after cleaning.
Immediately upon release of shaving head 18 out of recess 32, it will be appreciated that drive arm 26 is disengaged from detent 149 of spring 142 and, because of the resiliency of spring 142, arm portions 150, 152 immediately flex downwardly. lnner cutter 116 can slide freely along the length of outer cutter 112, but spring 142 and larger bosses 134 in base 110 cooperate so that bosses 134 serve as detents to keep inner cutter 116 from inadvertently separating from outer cutter 112 and falling to the floor, for example. When inner cutter 116 is in the position in which spring 142 encounters larger bosses 136, portions of spring 142 are available for manual depressing whereby cutter 116 can be removed from outer cutter 112 by sliding it out axially. Alternatively, cutter 140 can be grasped by the fingers and simply pulled free, the spring 142 giving way due to the neutral flexibility and resilience.
Removal of inner cutter 1 16 greatly facilitates cleaning of both inner cutter 116 and outer cutter 112, and a brush can be passed through the interior of outer cutter 112, for example. inner cutter l 12 is replaced in operating relationship with outer cutter 112 by reversing the steps described immediately above, and, again, it is noted that because of the bilateral symmetry of the shaving head assembly generally, and particularly because of the bilateral symmetry of the outer cutter 116 and inner cutter 112 along the longitudinal midsectional plane, theinner cutter 116 can be inserted starting at either end thereof into either end of outer cutter 112, and there is no right or wrong end-for-end insertion on re-assembly.
To replace the shaving head assembly 18 in recess 32, either side 90, 92 of head assembly 18 can be placed approximately against either surface 94 or 96 of recess 32 in housing 12 to bring the resilient latch portions 86-86 of detent 66 into mating latching engagement with detents 164--164 at the underside of base 1 10 of cutter head 18. Because of the rounded character of sides 94, 96, and opposing surfaces on head 18, inward or downward pressure on head 18 automatically causes a shifting about the long dimension until head 18 is secured by detent 66 in proper orientation.
Another aspect of the present invention involves the relationship between the lighting assembly generally indicated by the numeral 176 and the head portion 16. Lighting assembly 176 includes a lamp 178, a receptacle 180, diffusion lens 182 and associated electrical supply components generally indicated by the numeral 184. Emminently satisfactory lighting circuits and associated lighting circuit structures are disclosed in copending patent application Ser. No. 276,517 filed July 13, 1972 by Edward J. Brennaman et al. (Attorney Docket Case 720607) which application is assigned to a common assignee with this application.
In the illustrated embodiment, it is noted that head 18 is received in a low profile configuration, that is, with cutters 112 being no higher than, and, in fact, slightly recessed below, associated end walls 38, 40 of end portion 16 of housing 12.
Cutter head 18 is positioned on an inclined portion adjacent diffuser lens 182, with lens 182 being positioned to illuminate the users skin immediately adjacent the upper portion 186 of head portion 16. It is also noted that when shaver 10 is being operated in such a way that shaving head 18 is substantial 16 parallel with respect to the skin of the user, the portion 186 of head portion 16 of housing 12 will be elevated so that lens 182 is at an angle with respect to the skin, thereby permitting an increased illumination of the surfaces immediately ahead of the razor.
lt will be appreciated from a consideration of the foregoing disclosure that the shaver of the present invention provides a head configuration which is readily used for shaving curves, angles, recessed areas, and the like, and is adaptable and highly satisfactory for use in connection with shaving legs, underarms, and the like. It is also extremely convenient to remove shaving head 18 for cleaning or replacement and to remove cutter 112 from base for replacement. The invention is particularly suited for use in connection with a ladys shaver in that there is no need to exactly re-assemble head 18 in shaver 10, or inner cutter 112, or outer cutter 116 in base 110, in any particular end-for-end orientation. Moreover, new cutters can be installed in head 18 conveniently and easily without any tools. For example, cutters 112 can be separated from block 110 by pressing the point of a pencil through opening 168 and a replacement cutter 112 is aligned in slot 114 and is snapped to secure attachment.
Moreover, the cutter assembly 18 is readily rolled free of detent 66.
Moreover, the fact that cutter 112 is secured to a snap-out base 110 provides an additional advantage referred to hereinbefore. Because of the novel roll-out action imparted by the shaving head ejector 104 described hereinbefore, the shaving head 18 is disengaged from detent 66 in a motion which corresponds approximately to a roll or pivot around an axis which is parallel to the long dimension of head 18. This is a substantial improvement over ejection systems which impart a roll or pivot around an axis which is parallel to a transverse or narrower dimension of a cutter head. As a consequence of this combination of structural elements, end walls 30, 40 can be and are spaced-apart to very snugly "cutter 112 be the same length as base 110 because this relationship better assures that end walls 38-40 provide immovable positioning support for cutter 112 during operation.
