  • FIG. 1 an electric dry shaver designated generally by reference numeral 11.
  • the shaver includes a boxlike housing 12 on which is superimposed a shaving head assembly 13.
  • the housing 12 is formed by two interfitting housing members 1.4 and 15 which abut to form a housing with an outwardly facing opening 16.
  • the shaving head assembly 13 is received within the opening 16 and cooperates with the housing 12 to form an enclosure 17 within which a motor 18 and batteries 19 are mounted.
  • the batteries 19 are of the rechargeable variety, and suitable means are provided for connecting the batteries 19 to an external power source for recharging purposes.
  • the batteries 19 are electrically connected to the motor 18 through a switch 20 which controls the energization of the motor 18.
  • the shaving head assembly 13 is made up of an outer frame 24 which has an open, somewhat rectangular shape and an inner frame or motor supporting block 25.
  • the outer frame 24 and the inner frame 25 are secured together by means of the motor assembly screws 26 which are best shown in FIGS. 2 and 4 as extending through motor brackets 27, through support pads 28, inner head frame 25, and into threaded engagement with the outer head frame 24.
  • the shearing elements in the head assembly 13 comprise an outer shearing member or perforated comb 30 and a pair of inner cutter assemblies 31.
  • the perforated comb 30 is a thin, flexible member which is secured to a supporting frame 32 whereby the comb assumes a double arched or M-shape, as is best shown in FIGS. 1 and 2.
  • the structure of the comb 30 and the inner cutter assemblies 31 made up of the cutting blades 33 and supporting shafts 34 are well known in the art, and their action need not be described in detail herein.
  • This enclosure 40 provides a receptacle for the clipped hair so that it will not be deposited in unwanted areas during or after the shaving operation.
  • the frame 24 is shaped to provide a depression or recess between spaced end walls 24a and 24b.
  • the comb 30 overlies this recess and together with the inner head frame 25 forms the enclosure 40.
  • a hinge plate 41 For the purpose of supporting the comb 30 and relating it to the shaving head assembly, there is provided a hinge plate 41 as is best shown in FIGS. 2, 7, 8, and 9.
  • the hinge plate 41 is formed along one edge with a lengthwise extending, inturned flange 41a which cooperates with an assembly plate 42'to pivotally connect the hinge plate to the remainder of the shaving head assembly 13.
  • the assembly plate 42 extends across the upper surface of the inner head frame and is held against the upper surface of the frame 25 by the outer head frame 24 which more or less sandwiches the assembly plate 42 therebetween.
  • the assembly plate 42 is formed of spring steel and includes an unsupported edge 42a which is under tension against the intumed flange 41a of the hinge plate 41.
  • the portion of the edge 42a which is in engagement with the inturned flange 41a formed with a lengthwise extending channel 42b which engages in the inturned flange 41a and permits limited, pivotal movement of the hinge plate 41.
  • the hinge plate In order to connect the comb and its supporting frame 32 to the hinge plate 41, the hinge plate is formed with inwardly extending protuberances 41b which extend through openings in the comb 30 and the supporting frame 32. These openings in the comb and frame are large enough to permit pivotal movement of the comb and frame with respect to the hinge plate 41 as is evident from FIGS. 7 and 8.
  • a retaining and biasing spring 44 is secured to the inner surface of the hinge plate and the unsupported portion of the biasing spring 44 overlies and engages the edge of the supporting frame 32 and applies a biasing force against the frame 32 and the comb tending to rotate the comb counterclockwise about the upper edge of the hinge plate 41 as shown in FIGS. 7 and 8.
  • This assembly including the hingeplate 41, the comb 30, and its supporting frame 32, may be termed a comb assembly 45 and is pivotally related to the remainder of the head assembly 13 by the interengagement of the intumed flange 41a and the unsupported edge 42a of the assembly plate 42.
  • a latch means 50 which is located primarily between the assembly plate 42 and the inner head frame 25.
  • the latch means 50 consists only of three parts; a latch member 51, a biasing spring 52, and a manual actuating button 53.
  • the latch member 51 is an inverted, channel-shaped member which is received and guided in a groove or recess 25a formed 7 in the upwardly facing surface of the inner head frame 25.
  • the spring 52 engages the left end of the recess 25a as shown in FIG. 8, while the other end of the spring engages a cross bar 53a formed on the button 53.
  • the cross bar 53a in turn engages a downwardly extending projection 51a on latch member 51 thereby resulting in the latch member 51 being biased by spring 52 to the right as shown in FIG. 2.
  • the projection 510 extends into an opening 53b in the button 53 so that the button 53 and the latch member 51 move as a unit in the slot 25a.
  • the latch member 51, the biasing spring 52, and the actuating button 53 are retained in the slot 25a by the assembly plate 42 which overlies the inner head frame 25 as is best shown in FIGS. 4 and 8.
  • the assembly comprising the latch member 51 and the button 53 is prevented from moving outwardly from the right end of the slot 25a, as shown in FIG. 2, by means of an upwardly extending post 25b formed in the bottom of the recess 25a.
  • the housing member 14 is provided with a notch 14a along its upper edge which forms an opening with the lower edge of the frame 24 through which the exposed end of the button 53 extends.
  • the latch member 51 is formed with an upwardly and outwardly extending projection 51b as is shown in FIGS. 3, 5, 6, 7, and 8.
  • the projection 51b engages a corresponding opening 320 in the comb supporting frame 32.
  • the operator applies an inward force against the actuating button 53. This force compresses the spring 52 and causes the latch member 51 to move inwardly withdrawing the.
  • the retaining and biasing spring 44 mounted on the hinge plate 41 causes the comb 30 and frame 32 to pivot upwardly with respect to the head frame 24 as well as the hinge plate 41 as shown in FIG. 8.
  • the inertia of the comb 30 and frame 32 causes the comb assembly 45 to continue moving toward its open position in which the hinge plate 41 is pivoted outwardly as shown in dotted lines in FIG. 8. In this position, the volume formerly in enclosure 40 is well exposed for cleaning purposes.
  • the comb 30 and hinge plate 41 are merely pivoted back to the original position shown in FIG. 2 at the same time the actuating button 53 is depressed to move the latch projection 51b to a retracted position so that the frame 32 may be moved to its fully closed position, and upon release of pressure on the button 53, the latch projection 51b againmoves into engagement with the frame 32. Accordingly, there is provided a simple and effective means to provide access to the inner cutter assemblies 31 and the enclosure 40 within which the hair or beard clippings are received and stored. Thus, the shaver 11 may be cleaned, and the inner cutter assemblies 31 serviced with a minimum amount of effort and with little opportunity oflosing the head parts or reassembling the parts improperly.
