Definitions

  • Characteristic of the razor of the present invention is that there is provided two blade clamping plates formed of synthetic material, that is plastic, wherein the blades are held between a rigid and a resiliently pressed blade clamping plate, these blade clamping plates being provided with a respective gripping component which, when assembled, collectively form a tapered socket, with such gripping components being held together in their mutual position by means of a casing or housing sleeve.
  • the safety-razor can be disassembled by removal of a gripping component, more specifically, by removing the casing serving as a handle.
  • a special spring for iixedly clamping the blade is not necessary since one blade clamping plate is constructed to be self-springy. Additionally, the manufacture from plastic represents a considerable saving in costs.
  • the resiliently pressed blade clamping plate is provided with recesses for the purpose of producing a spring action.
  • the resiliently pressed blade clamping plate can also be constructed as a separate element and can be subjected to the spring action of a separate gripping member or component provided with recesses.
  • the gripping components or members are, for example, assembled together in the lengthwise direction into a tapered socket or sleeve, held together by means of a casing means provided with an inner cone or inside taper.
  • a casing means provided with an inner cone or inside taper.
  • a thr-ead-type lock In order to secure the interconnection between the gripping cornponents and the casing means it is possible to employ a thr-ead-type lock, a bayonet-type lock or a snap or springtype catch or lock.
  • the one clamping plate can bear with an inclined surface against an appropriate surface of the other clamping plate.
  • the inclined surfaces are advantageously located within the gripping components and are pressed against one -another by means of the casing means.
  • the blade clamping plates In order to reduce wear it is recommended to provide the blade clamping plates with a bearing or support plate formed of metal. It is possible to apply to the support plate hooks serving as support means for the cutting edge of the razor blades.
  • the support plate can be form-lockingly connected with one of the blade clamping plates. It can be connected to pins of the aforesaid one blade clamping plate and by means of flexed portions can laterally enage over such clamping plate. Between both of the blade clamping plates there can be located a slot for introducing an insert portion or element operably connected with the blade dispenser or magazine.
  • one blade clamping plate can possess a lateral shoulder or projection into which a slot of the other clamping plate can be pushed thereinto. It has been shown to be advantageous to provide the casing, serving as a handle, with knurls or grooves at its external surface or face for the purpose of ensuring positive handling.
  • FIGURE l is a side view of a first embodiment of inventive safety-razor, with a portion of the casing removed in order to expose the internal construction;
  • -FIGURE 2 illustrates a front View of the resilient or elastic blade clamping plate
  • FIGURE 3 is a fragmentary cross-sectional view of the casing means
  • FIGURE 4 is a top plan View of the support or bearing plate
  • FIGURE 5 is a side View of the support or bearing plate depicted in FIGURE 4;
  • FIGURES 6, 7, 8 and 9 depict a portion of modified resilient blade clamping plates possessing different forms of slots.
  • FIGURE l incorporates a rigid blade clamping plate 1 and a resilient or iiexible blade clamping plate 2, between both of which there is fixedly clamped the relatively rigid or stiff razor blades 3.
  • the plate 2 at its upper part neighboring the blade, acts as a seat for the blade and defines a flat surface.
  • the clamping plates 1 and 2 formed of plastic include tapered portions d and 5 respectively, which each case are integral with a respective half-conical gripping portion 6 or 7 respectively.
  • the respective tapered portions d and 5 together with their associated gripping portions d and 7 respectively, provide gripping components.
  • the blade clamping plates 1 and 2 are held together at their gripping portions d and 7 respectively, by means of casing means ii provided with an inside taper or cone 9 and conveniently serving as a handle.
  • the lower end of the gripping portion 7 bears by means of an inclined surface 1t) against a similar surface 11 of the other gripping portion 6, whereby the first gripping portion 7 has imparted to it a force in the direction of the arrow 12 and thereby xedly clamps the razor blade 3.
  • the external surface 13 of the casing means 8 there are provided knurls or suitable grooves in order to ensure for a positive handling and holding of the razor.
  • a safety or securing mechanism for example in the form of a pin 1d arranged at the gripping portion 6 which engages in a threading or threaded portion 15 of the casing means 8, thereby providing a thread-type lock.
  • the tapered portion 5 exhibits lateral slots 16 and 17 and a substantially central closed slot 18. Due to this physical construction the elasticity of the tapered portion 5 is increased. It is thus permitted to bend and ex transversely to the said flat surface defined by the upper part of plate Z--that is, to move forward in the view of FIGURE l--and also perpendicularly to the plane. In the clamped condition the slots 16, 17 and 13 are deformed, so that they approximately assume the form depicted in phantom lines in FIGURE 2.
  • a transverse or lateral slot 19 is located between the blade clamping plates 1 and 2 spaced at this location and serving to permit introduction of an insert portion or key of the blade dispenser or magazine.
  • This insert portion is constructed such that when it is introduced into the transverse slot 19 the clamping plates 1 and 2 are resiliently spread apart and release the blade 3. Due to the lateral pushing-in of a new blade from the dispenser the old blade is removed. After withdrawing the insert portion of the blade dispenser from the razor the blade 3 is again fixedly clamped.
  • a support or bearing plate 20 having apertures or holes 21a and 22a which seat upon pins 21 and 22 respectively, of the blade clamping plate Z, in order to form-lockingly connect such support plate 20 therewith.
  • This support plate 20 is further provided with flexed portions 23 which laterally engage over the aforesaid blade clamping plate 2.
  • hooks 24 and 25 At the forward end ⁇ of the support plate 20 there are located hooks 24 and 25 which protect the blade cutting edge against falling-out and against protruding too much towards the front.
  • An opening or passage 26 is located beneath the blade cutting edge at the blade clamping plate 2 and which serves the purpose of ensuring that such cutting edge is freely exposed.
  • FIGURE 6 illustrates an embodiment which is quite similar to FIGURE 2, yet the central slot 18a is provided with substantially parallel confronting faces ISb. Also, the diametrically opposed ends 5a of the tapered portion 5 are rounded and merge with a narrower leg portion 5b.
  • the transfer or tapered portion 5 is only provided with lateral or side slots 50 and 5I formed by the substantially Z-shaped arranged webs or legs 50a, 50h and 50c.
  • the tapered portion 5 there is provided for the tapered portion 5 a considerably larger central closed slot 52, so that only thin Webs 53 remain, in order to obtain a softer spring. It will also be seen that, in this instance, there are also present the lateral slots 54 and 55.
  • the tapered portion plate 5 is provided with a single, closed central slot 56.
  • An injector-type safety razor of molded synthetic plastic including: ⁇ an elongated handle; a longitudinal hollow in said handle communicating with one end thereof; a stiff first member dening at one end a clamping plate for a blade and at the other end an elongated member for removable insertion in said hollow; means defining a blade seat and a at surface for the seat; iirst means dening two ends, one end including an extension that is elastic at least in the directions transverse and perpendicular to said at surface, for resiliently urging said blade seat against said first member, whereby to hold a blade therebetween, and for permitting insertion of the key of a blade injector magazine, and the other end dening an elongated member for insertion in said hollow; second means associated with said elongated members to ensure their correct orientation with respect to one another in the hollow; third means associated with said handle for orienting said two elongated members.
  • the elastic extension of said first means includes at least one slot transverse to said first means for ensuring the elasticity; said hollow tapers towards the end of the handle remote from the blade end of the razor, said elongated members also being tapered; said second means includes a flat surface associated with each of said elongated members, said surfaces bearing on one another when the elongated members are inserted in the hollow; and wherein the flat surface of the elongated member of said first member terminates in an inclined surface extending outwardly and downwardly from the flat surface; and the flat surface of the elongated member of said first means terminates in an inclined surface mating with the other inclined surface; said hollow tapers towards the end of the handle remote from the blade end of the razor, said elongated members also being tapered, the tapers of the elongated members and of the hollow cooperating to push said inclined surlfaces against one another and to force said rst means to move in the direction of the blade; and said fourth means engages in said third means to prevent longitudinal
