Definitions

  • the present invention relates to razor blade cartridges or blade assemblies for use in wet shaving.
  • Such cartridges or assemblies usually comprise a pair of blades separated by a spacer having staggered or offset blade edges and the cartridge or blade assembly is operable to make a connection with a razor handle in well known fashion.
  • the present invention is more particularly concerned with an improvement of a cartridge such as that disclosed in U.S. Patent No. 3,964,159 in which a plastic cap 12 is permanently and rigidly staked to a seat or support 14 and blades 16 and 18, straddling a spacer 20, are sandwiched between the cap and support with proper blade edge exposure.
  • blade means is intended to designate one or more blades within a given blade cartridge or blade assembly.
  • a blade cartridge of the type comprising a cap and a support element provided with blade means securely staked thereto, said blade means having at least one cutting edge and being sandwiched between the support element and the cap, said cutting edge being permanently exposed at the proper position relative to the cap and the support element to permit wet shaving characterised in that:
  • the reference numeral 11 designates a blade cartridge having a channel 12 for making a separable connection to a mating handle 13 in well known fashion.
  • the cartridge includes a blade support.14, blade means 16 and movable cover 17.
  • Figure 1 shows the cover 17 in the first or closed position while Figure 2 shows the cover 17 retracted to the open position properly exposing blade means 16 for wet shaving.
  • the cover 17 engages the assembled blade support 14 and blade means 16, permanently but slidably, by means of a track-slide arrangement with appropriate stop means for limiting the stroke of the cover. Motion is effected by grasping the knurls 18 on opposed end walls or skirts 20 of cover 17 and noving cover to and fro in direction of arrows labelled 19 while restraining the handle 13 and thus the blade assembly.
  • FIG. 3 shows a prior art cartridge of the type disclosed in said 3,964,159 patent in which the cover C, the blade means B, spacer and blade support S are staked and fixed permanently into a rigid assembly, the blade means exposure having been set permanently at the time of manufacture.
  • FIGS 4 through 8 show the slidable cover 17, blade means 16, spacer 21 and blade support 14.
  • blades 16-16 and spacer 21 are staked rigidly to blade support 14 by rivets 22-22.
  • Cover side walls 20 formed with recesses 23-23 define a slide engaging a track 24-24 formed on the blade support 14.
  • the track 24-24 for purposes of claiming the invention, is sometimes referred to as a guide means and may be formed on the assembled blade means and blade support as manufacturing considerations and good design dictate.
  • the cover 17 makes a permanent but sliding connection with the blade support in that side walls 20 terminate in claws 26-26 which flex outwardly and inwardly to make a snap fit to the underside of the track 24 when the cover is assembled to the track.
  • the interior of the cover side walls and the ends of the blade assembly are formed with stop elements cooperating to define stop means.
  • the stop means defines a stop element 27 on the interior of each cover skirt 20 having opposed shoulders 28 and 29 operative to engage mating stop elements 31 and 32 on the blade assembly.
  • the dotted line position of the cover 17 denotes the closed or first position of the cover and in this position shoulder 29 of top element 27 abuts mating stop element 32.
  • the solid line position shows the cover 17 in the open or second position with the shoulder 28 of stop element 27 abutting stop element 31 of blade assembly, thereby exposing the blade edges properly for wet shaving.
  • stop elements Obviously the disposition and conformation of stop elements is a matter of engineering choice consistent with proper blade edge exposure in the open position and proper blade protection in the closed position.
