Definitions

  • the invention relates to a razor head, in particular a razor blade unit, with a plastic housing with a blade platform on which a single or double razor blade can be inserted from above onto the plastic housing and rests on the blade platform, as well as with a cover that can be plugged onto the plastic housing and locked with it the and the blade platform of the plastic housing the single or double razor blade is fixed.
  • a single or double razor blade is embedded in the shaver head in a plastic housing.
  • “Insoluble” is understood to mean that an exchange of a used razor blade for a new one is not intended. If the razor head is designed separately and can be attached to a handle, for which purpose the handle and the razor head have interlocking devices that correspond to one another, this is referred to as a so-called razor blade unit.
  • a razor blade unit for a wet shaver in which a double razor blade is permanently fixed between a blade platform of a plastic housing and a cover that can be snapped onto the plastic housing.
  • a spacer is arranged between the two razor blades, these three parts being mounted separately from one another and not forming a structural unit.
  • the underside of the cover has conically tapering pins, onto which the two razor blades can be plugged together with the spacer by means of corresponding through-bores.
  • the cover in the area of the side walls has inwardly directed latching lugs, which engage around the plastic housing with it.
  • openings have to be formed in the razor blades for fixing the position of the double razor blade within the razor blade unit.
  • the cover is locked in the area of the side walls.
  • the object of the invention is to further develop the known razor head in such a way that the fixing of the single or double razor blade within the razor head is improved.
  • an opening is formed in the plastic housing, into which the single or double razor blade can be inserted from above into the plastic housing and fixed in position in the blade plane, and that the cover has a push-fit that can be pushed onto the plastic housing from behind, essentially over the length of the plastic housing extending cap with an im is substantially U-shaped cross-sectional shape.
  • a razor head designed according to this technical teaching has the advantage of a technically very simple and secure attachment of the single or double razor blade within the razor head. It is only necessary to insert the single or double razor blade into the opening of the plastic housing from above, as a result of which the single or double razor blade is already in its final position within the razor head, in order to then put the cap on for final fixing.
  • the cover in the form of the cap according to the invention represents a technically very easy-to-use and, above all, secure cover for fixing the single or double razor blade within the razor head, by pushing the cap onto the plastic housing from behind to grip it. The upper leg of this cap forms the cover cap.
  • the cap also has advantages if the plastic housing is wrapped together with the single or double razor blade in a further development with wire, since the encircling cap additionally fixes the wire windings on the plastic housing and forms additional protection against lateral slipping.
  • the cap has at the end in each case a latching arm which extends forward and has a latching lug, the plastic housing having a latching recess corresponding thereto.
  • the cover which is made in particular of plastic, be provided with a sliding film.
  • a sliding film can reduce the coefficient of friction between the razor head and the skin of the user during the shave, so that a comfortable shave is made possible due to the low friction.
  • the plastic housing is wrapped with wire together with the single or double razor blade before the cap is put on.
  • this wire wrapping creates a first fixation of the single or double razor blade within the opening of the plastic housing, on the other hand, the wire wrapping prevents the user from accidentally cutting at the cutting edge of the razor blade and injuring it.
  • FIGS. 1 to 3 show the various phases of the assembly of a razor blade unit 1, while FIG. 6 shows a complete sectional razor 2 in a schematic sectional view, in which the razor blade unit 1 from FIGS. 1 to 3 at the front end of a handle 3 is attached.
  • This handle 3 or parts thereof are shown in FIGS. 4 and 5.
  • the razor blade unit 1 consists of a one-piece plastic housing 4. This has a front guide bar 5, two side walls 6 and a blade platform 7 on the inside.
  • a double razor blade consisting of the two razor blades 8, 8 'is inserted from above through an opening 9 formed in the plastic housing 4.
  • the two razor blades 8, 8 'on a flat, elongated, cuboid spacer 10 are so permanently attached that the spacer 10 is sandwiched between the two razor blades 8, 8'.
  • the razor blades 8, 8 'and the spacer 10 thus form a so-called razor blade / spacer unit 11.
  • the spacer 10 is somewhat longer than the two razor blades 8, 8', so that the spacer 10 slightly over the ends of the razor blades 8, 8 'survives.
  • the blade platform 7 of the razor blade unit 1 has a recess 12 on both sides in the region of the side walls 6.
  • a cap 14 with an essentially U-shaped cross-sectional profile is used for this purpose.
  • the cap 14, which extends over the entire length of the plastic housing 4 has a latching device 15 on the upper side. This consists of end-side latch arms 16 which each have a latch 17 at their front ends. Corresponding to these locking lugs 17, the plastic housing 4 each has a locking recess 18.
  • FIG. 3 Because the top of the cap 14 rests on the razor blade / spacer unit 11, the latter is fixed firmly on the blade platform 7 of the plastic housing 4.
  • a handle 3 is provided for the razor blade unit 1. This has a special fork holder 19 at its front end, by means of which the handle 3 can be snapped into the razor blade unit 1.
  • This fork holder 19 consists of a spring 20 in the form of a wire spring. This is in itself without in Fig. 4 the handle 3 shown.
  • This spring 20 initially consists of a U-shaped base spring element 21, the front leg ends of which are bent vertically outwards and form fork arms 22. The front ends of the fork arms 22 are bent in an S-shape and form bearing pins 23.
  • FIG. 5 shows how the spring 20 of the fork holder 19 is arranged in the front area of the handle 3.
  • the base of the U-shaped base spring element 21 is fixed within the handle 3 in such a way that the legs extend forward.
  • the fork arms 22 come to lie in a T-shaped extension 24 of the handle 3.
  • the legs of the basic spring element 21 are exposed in the front area.
  • actuation areas B are formed so that the bearing pins 23 of the spring 20 can be pivoted inwards toward one another by compressing the legs of the base spring element 21. This is indicated by the arrows P ⁇ . After releasing the bearing pins 23 return to their starting position.
  • a so-called zero-position spring 25 can be seen in FIGS. 4 and 5.
  • this is designed as a leaf spring made of plastic or metal and is mounted with its lower end in the handle 3.
  • it can also be designed as a U-spring, as a leg spring, etc.
  • the technical meaning of the zero position spring 25 will be explained later with reference to FIG. 6.
  • the journals 23 are first pivoted inward in the manner described.
  • the fork holder 19 can be inserted into the razor blade unit 1, as can be seen in particular in FIGS. 3 and 6.
  • the razor blade unit 1 is each provided in the region of its side walls 6 with a recess 26 into which the bearing pins 23 of the fork holder 19 engage after the spring 20 has been released.
  • the pivot axis S defined by the bearing pin 23 lies in the region of the cutting edge 27 of the front razor blade 8, ie the pivot axis S runs in front of this cutting edge 27 parallel to it and somewhat offset below the plane of this front razor blade 8 6, the zero-position spring 25 presses the razor blade unit 1 forward against a stop 28 inside the plastic housing 4. During the shaving process, the razor-blade unit 1 can thus only be pivoted backwards against the force of the zero-position spring 25, the Swivel range is between 15 ° and 30 °.
