Definitions

  • ABSTRACT A holder for a shaving unit, theshaving unit consisting of a substantially rigid member to which a razor blade is secured in [30]
  • Forelgn Application Pmmy Data a permanent manner with the rigid member having a guard Jan. 28, 1969 Great Britain ..4,754/69 surface located at a preset spacing from the cutting edge of the blade, comprising a catch which is movable between a first [52] US. CL ..30/64, 30/3465 position at which it retains a shaving unit in'the holder and a [51] Int. Cl.
  • a holder for a shaving unit said shaving unit consisting of a substantially rigid member to which a razor blade is secured in a permanent manner with the rigid member having a guard surface located at a preset spacing from the cutting edge of the blade, wherein said holder comprises selectively operable means for ejecting a shaving unit from said holder when the shaving unit is to be replaced.
  • the invention also provides a holder for a shaving unit, said shaving unit consisting of a substantially rigid member to which a razor blade is secured in a permanent manner with the rigid member having a guard surface located at a preset spacing from the cutting edge of the blade, comprising a catch which is movable between a first position at which it retains a shaving unit in the holder and a second position at which it no longer retains said shaving unit in the holder, and means for initiating movement of said shaving unit out of said holder when said catch is moved to said second position.
  • FIG. 1 is a rear elevation of the holder with part of the rear cover broken away to show the inside of the holder;
  • FIG. 2 is a part sectional side elevation of the holder
  • FIG. 3 is an underneath view of the shaving unit
  • FIG. 4 is a sectional side elevation of the head of the holder on a larger scale than that of FIG. 2;
  • FIG. 5 is a similar view to FIG. 4 showing the shaving unit being ejected from the holder.
  • FIG. 6 is a front view of the head of the holder on an enlarged scale, with the shaving unit in position, partly broken away to show the inside of the head of the holder.
  • the drawings show a shaving unit having a razor blade 19 secured in a permanent manner to the substantially rigid body of the shaving unit 20 with a guard surface 200 located at a preset spacing from the cutting edge of the blade 19.
  • a shaving unit 20 is located in the holder 21 between jaws 22 and 23.
  • the jaw 22 has end locating surfaces 22a for positioning the shaving unit 20 relative thereto, the rigid body of the shaving unit 20 having cooperating surfaces 20b for engagement with locating surfaces 22a on the holder 21.
  • the shaving unit 20 being held in position by engagement of the head 25a of a spring-loaded detent 25 within an aperture 26 (see FIG. 4) in the underside of the shaving unit 20.
  • the shaving units will normally be stored in a dispenser, for example of one of the kinds described and illustrated in British- Pat. specification 1,160,542.
  • a shaving unit 20 When a shaving unit 20 is to be withdrawn from a dispenser by use of the holder 21, the jaws 22 and 23 of the holder are presented to the rear of the shaving unit 20 so that the inner surface of the lower jaw 23 will engage with the underside of the shaving unit 20 and the inner surface of the upper jaw 22 will engage with the upper surface of the shaving unit 20.
  • the head 25a of the detent 25 engages with a cam surface 27 (FIGS.
  • an ejector button 29 which projects from the rear of the holder 21 is depressed and causes 1 forward movement of the upper end of a cantilever ejector spring 30.
  • the engagement of the upper end of spring 30 with the rear edge of the shaving unit 20 causes the shaving unit to move outwardly from the jaws 22, 23 of the holder with consequent depression of the detent 25 against the reaction of spring 28 thereby releasing the detent from its engagement in the locating aperture 26 as shown in FIG. 5.
  • the curved surface 25a of the head of the detent 25 rides out of the aperture 26 and comes into engagement with the initial portion of cam surface 27.
  • the two coiled portions 31, 32 of spring 28 fit respectively over lugs 33, 34 of detent 25 and the central link portion 35 of spring 28 bears on the underside 36 of detent 25.
  • the two end links 37, 38 of spring 28 fitrespectively in recesses 39, 40 provided in the rear component 24 of the holder with the head of the detent 25 located in a central slot 41 in the jaw 23.
  • the detent 25 and spring 28 are located in position by the engagement of the front component 42 with the rear component 24.
  • Balance weights 43, 44 are secured to the inner face of the front component 42.
  • a shaving unit comprising a substantially rigid member having a guard surface on its forward edge portion for contact with the skin and an elongated blade thinner than said rigid member and having a cutting edge, said blade being permanently fixed to said rigid member with its cutting edge parallel to, and spaced from, said guard surface in shaving relation to the latter, said rigid member having a portion of its surface formed as a cam surface of predetermined shape, and a handle having a transverse support including clamp jaws forming a transverse opening therebetween for receiving said rigid member therein with the cutting edge extending outwardly from said opening, one of said jaws having locating surfaces for positioning said shaving unit relative thereto, said rigid member of said shaving unit having cooperating surfaces for engagement with said locating surfaces on said handle, said handle also having means associated with one of said jaws for engaging said rigid member and holding the same on said support, said engaging means being urged by resilient means into engagement with said rigid member and means for transmitting pressure, applied by the user, to said rigid member to disengage said rigid member from said one of the jaws and simultaneously
