Definitions

  • ABSTRACT An electric shaver particularly adaptable for use as a ladys shaver, having a detachable pop-out shaving head which is snugly positioned between fixed end walls.
  • the detachable shaving head includes an integral base having a slot into which an outer cutter is releasably secured.
  • the entire head assembly is pivotally released from between the end walls by a user oper ated head ejector which causes the head to pivot about axes perpendicular to said end walls.
  • the shaving head includes rows of brushes extending along both sides of the cutter.
  • the head portion of the shaver includes a special lighting assembly adjacent the shaving head for illuminating the skin adjacent the shaver.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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-
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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
  • 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.
  • a small pushing tool (not shown) can be brought to bear against the bottom 128 of bridge element 126 of outer cutter 1 12.
  • FIG. 3 shows the cutter head 18 in a moved position
  • the ejection mechanism can move to several positions in a direction corresponding to the lengthwise direction of handle portion 14.
  • surface 94 of ejector 104 bears under rounded side 90 of head 110 and urges shaving head 110 to pivot.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • new cutters can be installed in head 18 conveniently and easily without any tools.
  • 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.
  • the cutter assembly 18 is readily rolled free of detent 66.
  • cutter 112 is secured to a snap-out base 110 provides an additional advantage referred to 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.
  • 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.
