Definitions

  • This invention relates to safety razors in general, and more particularly is directed to a new and improved means to prevent over-tightening of a razor blade clamped in the safety razor.
  • the clamping force applied to the razor blade depends to a large degree upon the amount of rotational force applied to the knob means which, on rotation, serves to open and close the cap sections on the razor.
  • the amount of rotational force applied will vary with the individual user and thus the amount of clamping force applied against the blade in the razor will also vary.
  • the clamping force affects the blade exposure, it is varied accordingly. While certain compensations can be allowed in manufacture and design in an attempt to eliminate the wide variance of blade exposure, the precision characteristics of the safety razor makes it highly desirable to provide uniform clamping force in all instances independent of the rotational force applied by the user in order to provide for a higher degree of shaving comfort and safety.
  • the present invention is directed to a new and improved drive means which is operable to insure uniform clamping force on the razor blade independent of razor closing force applied by the user.
  • Suitable means is provided which releases the driving connection when the resisting force reaches a predetermined value. While such release may be readily detected by the user, addition-a1 means is included to provide an audible indication to inform the user that the proper clamping pressure has been attained and the razor is ready for use.
  • a conventional blade clamping means is operated between opened and closed positions by the novel drive means of the present invention.
  • the drive means includes a drive knob and stem with a spring means interposed therebetween. When the clamping force on the razor blade reaches the designed value, slippage occurs in the drive knob and spring. At that time, an audible indicating means serves to alert the user of such occurrence and later also serves as a positive drive between the knob and stem during unclamping of the razor blade.
  • An object of this invention is the provision of means to limit the total clamping force which may be applied to a razor blade in a safety razor.
  • his a further object of this invention to provide a new and improved safety razor having means to prevent the application of excessive clamping force to a razor blade positioned in said razor.
  • FIG. 1 is an exploded perspective view of a double edge safety razor incorporating the principles of the present invention
  • FIG. 2 is a side elevational view of the safety razor of FIG. 1 in the assembled condition with the head and one-half of the handle shown in axial cross section;
  • FIG. 3 is an enlarged axial cross sectional view of the lower end of the handle assembly of FIG. 2 illustrating the detailed features of the drive means of the present invention
  • FIG. 4 is an enlarged perspective view of the ratchet stem forming a part of the driving assembly between the knob and spider stem;
  • FIG. 5 is an enlarged perspective view of the ratchet spring which forms a part of the audible indicating means of the present invention.
  • the safety razor 10 includes a spider assembly 11 received in a handle assembly 12 for axial shifting movement in order to permit insertion and removal of a razor blade with such shifting being achieved through a clamping drive assembly indicated generally at 13.
  • the spider assembly 11 is composed of a spider stem 14 joined to a spider 15 which has transverse arms 16 and 17 disposed at opposite ends. Cap sections 18 and 19 are carried on the transverse arms 16 and 17 for pivoting movement to open and close in response to shifting of the spider stem 14 in a manner well known in the art.
  • the handle assembly 12 includes a guard or blade supporting platform 20 joined to an attaching neck 21 which in turn is joined to a handle 22 having a generally frustoconical over-all contour.
  • the handle may have ribs formed along its outer circumference to enhance the ease with which the razor may be gripped and also improve the over-all appearance.
  • the clamping drive assembly includes an annular bearing 23 adapted to be received in the handle 22 for mounting a ratchet stem illustrated generally at 24.
  • a torsion type annular spring 25 is positioned around the ratchet stem 24 and is dimensioned so as to be expanded outwardly when received internally of a driving knob 26 as will become apparent.
  • a retaining washer '27 holds the clamping assembly to the spider stem 14 while a ratchet spring 28 coacts with a lower portion of the ratchet stem providing an audible indicating means to indicate that a predetermined level of clamping force has been attained and forms a positive drive during unclamping rotation of the drive knob 26.
  • An end cup 29 serves to hold the ratchet spring within the knob 26 in operative relation to the ratchet stem 24 as will be seen when a detailed description of FIGS. 2 and 3 is given.
  • the razor head indicated generally at 30 illustrates the spider assembly 11 and handle assembly 12 in operative or assembled relation with a razor blade 31 supported on the guard 20 and clamped by the cap sections 18 and 19 in the shaving position.
  • the cap sections are formed with downwardly projecting arms 32 and 33 at opposite ends which co-operate with respective grooves 34 and 35 (FIG. 1) on the guard 20 to cause the cap sections to open and close in response to axial shifting movement of the spider stem 14.
  • the force applied to the razor blade 31 through the cap sections 18 and 12 will vary the blade exposure or angle as it is sometimes referred to. Accordingly, it is imperative, because of the critical tolerances and blade placement, that the clamping pressure be uniformly applied by each individual user in order for the blade exposure to conform to that anticipated based on the design of the razor and thereby permit shaving in the manner expected.
  • the novel clamping assembly 13 shown at the lower portion of the handle 22 has been provided.
  • the lower end of the spider stem 14 is threaded as at 36 for co-operation with internal threads 37 formed in the central bore 38 of the ratchet stem 24. Relative rotation between the ratchet stem 24 and the spider stem 14 causes relative axial shifting therebetween to accomplish opening and closing of the razor.
  • the outer contour of the ratchet stem 24 includes a knob 39 of frustocon-ical shape which terminates in a radially extending shoulder 40 extending between the knob 39 and a bearing portion 50.
  • An opposite facing shoulder 41 is formed in the opposite end of the bearing portion 50 by its intersection with an annular circumferential portion 42 of increased diameter.
  • An annular land 43 is defined by radial shoulders 45 and 46 which land is of larger diameter than the adjacent portion 42.
  • the shoulder 46 connects the outer circumferential portion of the land 43, while the outer radial shoulder 45 extends inwardly terminating at the junction with an annular spring seat section 44.
  • the spring seat section 44 is of uniform diameter extending to the lower end of the ratchet stem, which is serrated as at 47 by forming a series of notch-like formations 48.
  • the central axial bore 38 in the ratchet stem 24 is provided with a bore of increased diameter 49 at the lower end which forms an internal radial shoulder 65 adapted to engage the retainer washer 27 to limit the total upward movement of the stem 14.
  • the retainer washer 27 or an equivalent may be riveted or otherwise suitably joined to the lower end of the stem 14.
  • the bearing portion 50 on the upper end of the ratchet stem 24 is disposed between the shoulders 40 and 41 and receives the split sleeve bearing 23 so as to rotatably mount the ratchet stern within an annular bore 51 formed in the lower end of the razor handle 22.
  • a longitudinal key may be formed at molding in the bore 51 to co-operate with the ends of the split sleeve bearing 23 to prevent relative rotation between the handle 22 and the sleeve bearing 23. Accordingly, the sleeve bearing 23 supports the ratchet stem 24 for free rotation in the lower end of the handle 22 to thereby permit shifting of the spider stem 14.
  • a shoulder 52 is formed in the lower end of the handle 22 and transmits axial thrust applied at the lower end of the bearing 23 directly to the handle 22. Accordingly, when the cap sections are in the closed or clamped condition as in FIG. 2, the thrust on the shoulder 52 serves to hold the stem and cap sections closed on the guard or blade supported platform 20 in a manner well known.
  • the drive knob 26 may be formed of generally frustoconical design to merge smoothly with the over-all contour of the handle 22 and is provided with a central bore 53 having a radially inwardly extending annular land 54 which is slidably received between the lower end of the bearing 23 and the land 43 on the ratchet stem.
  • the lower end of the central bore 53- is interrupted by a pair of axially extending keyways 55 and 56 which are diametrically opposed to each other and serve a function to become apparent.
  • the torsion spring 25 is disposed between the central bore 53 in the drive knob 26 and the circumferential spring seat portion 44 on the ratchet stem 24. As is apparent in FIGS. 1-3, the torsion spring 25 has an in- I wardly projecting end 57 which is disposed at assembly in an axially extending groove 58 in the ratchet stem 24.
  • the axially extending groove 58 may :be formed by milling, sawing or the like and terminates short of the serrated portion 47 of the ratchet stem 24 in order to retain the spring 25 on the ratchet stem and enhance the ease in assembling the same within the drive knob 26. Upward and downward movement of the spring is limited by engagement with the radially extending shoulder 45 on the land 43 and the inturned end 57 engaging the lower end of the groove.
  • the torsion spring 25 is dimensioned relative to the central bore 53 so as to continuously be constricted thereby. Expressed in another manner, the torsion spring 25 in its free state is slightly greater in diameter than the central bore 53 so that on assembly into the knob 26, the two will be in frictional engagement and provide a driving connection between the drive knob 26 and the ratchet stem 24.
  • the total amount of interference or gripping LfOI'CB between the spring 25 and the central bore 53 on the driving knob 26 the total amount of downward force applied to the cap sections before release of the drive between the ratchet stem 24 and the knob 26 can be predetermined.
  • the end cup 29 holds the ratchet spring 28 positioned within the bore and closes the end of the internal bore 53 in the drive knob 26 to present a finished appearance.
  • the serrated end 47 of the ratchet stem 24 rotates relative to the ratchet spring 28 causing the tangs or tongues 63 and 64 to alternatively be depressed and released for extension to the free position illustrated, thereby to provide an audible indicating means in the form of a clicking sound serving to alert the user that the predetermined clamping force has been attained.
  • the free end portions of the tangs 63 and 64 engage the sides of the notches 48 to form a positive driving connection to rotate the ratchet stem 24 in the reverse direction and thereby release the clamping force on the razor blade.
  • the cap sections 1 8 and 19 are open by rotating the drive knob 26 in a counter-clockwise direction. During such rotation, tangs 63 and 64 engage the sides of the notches 48 to provide a positive drive. The razor 'blade 31 is then positioned on the guard, and the knob 26 rotated in a reverse or clockwise direction closing the cap sections 18 and 19. When the cap sections 18 and 19 reach the blade clamping position shown in FIG. 2, and rotation of the drive knob 26 is continued, slippage occurs between the spring 25 and the drive knob 26.
  • the ratchet spring 28 rotates with the drive knob 26
  • the tangs 63 and 64 are depressed and released as they move into and out of the notches 48 causing an audible sound alerting the user that the proper clamping force has been reached and that further rotation of the drive knob 26 has no effect on the clamping force.
  • novel razor design described above provides many advantages in the form of simplicity of design permitting economical manufacture and yet providing a novel means to prevent over-tightening of the razor blade.
  • novel audible indicating means adds to the economy of the design in that it also serves to provide a positive drive between the knob and ratchet stem. Since the blade is uniformly clamped, the proper designed blade exposure can be had regardless of the torque applied to the knob 26.
  • a safety razor comprising a razor head having means for clamping a razor blade therein, drive means to operate said clamping means, said drive means including a drive knob and a ratchet stem, torsion spring means operatively interposed between said drive knob and ratchet stem, said torsion spring having means thereon co-operating with said ratchet stem for rotation therewith and being positioned in frictional engagement within a bore formed in said drive knob, said ratchet stem being operative to open and close said clamping means in response to rotation of said knob, said torsion spring and said drive knob being adapted to rotate relative to one another on continued rotation of said drive knob, said relative rotation between said drive knob and said torsion spring preventing application of further clamping force on said razor blade after said razor blade has been properly clamped.
  • audible indicating means is provided in said knob and is operable on continued rotation of said drive knob to indicate that application of further clamping force on the razor blade is not possible, said audible indicating means including notch-like formations on said ratchet stem and a spring means having at least one resilient tongue engageable with one of said notch-like formations to .form a positive drive therebetween when said knob is rotated in a direction so as to unclamp said blade.
  • a safety razor comprising a blade supporting guard
  • a handle assembly joined to said guard, a spider assembly including a pair of cap sections and a spider stern, said cap sections being movable and co-operating with said guard to open and close in response to axial shifting of said spider stem, said spider stem being slidably received in said handle assembly, knob means mounted on said handle assembly for rotation relative thereto, drive means operable on rotation of said knob means to reciprocate said spider stern thereby to open and close said cap sections to release and clamp a razor blade on said guard, said dnive means including a ratchet 'stem threadably received on said spider stem, and an annular torsion spring means interposed between a part of said ratchet stem and said knob means, said torsion spring means being rotatably connected to said ratchet stem and having a portion thereof in frictional engagement with said knob means whereby said torsion spring means will rotate on rotation of said knob means thereby to rotate said ratchet stem until the clamping force on said razor blade has reached a magnitude at which time continued application of torque
