Definitions

  • the invention relates to a device for holding a shaving foil by means of its leg ends in the shaving head frame of a dry shaving apparatus.
  • a device for holding a shaving foil by means of its leg ends in the shaving head frame of a dry shaving apparatus.
  • Various types of dry shavers with such devices are known.
  • the shaving head of these apparatuses generally has the means for holding the shaving foil assigned to it, on the inside of which, as is known, a knife block comprising a plurality of knife blades slides along and cuts off the stubble stubble passing through the holes in the shaving foil.
  • This knife block is connected to the drive of the dry shaving apparatus by means of a suitable coupling and is pressed against the shaving foil by a spring.
  • the invention aims to provide a device for the elastic holding of the shaving foil within the shaving head of a dry shaving apparatus, which is characterized by a particularly simple and yet fully effective design and furthermore keeps the space enclosed by the shaving foil free from components of the holder.
  • leg ends of the shaving foil are designed as a roller spring and are held movably via guide elements provided in or on the shaving head frame.
  • the leg ends designed as a roller spring are expediently provided such that they can be rolled in or around the guide elements.
  • the guide elements are formed by longitudinally slotted tubular receptacles provided in the shaving head frame. According to another embodiment, the guide elements are formed from bearing rods or bearing bolts provided on the shaving head frame.
  • the elastic mounting of the shaving foil in the shaving head frame formed according to these embodiments has the advantage that when the shaving foil is tensioned via a knife block under spring pressure, the rolled leg ends curl up more tightly in a spiral and roll back or spring back into their initial position as a result of the inherent spring tension , so that a good contact of the knife block on the inside of the shaving foil is always guaranteed.
  • the leg ends can be formed in a rolled shape on the shaving foil.
  • legs of rolled shape can also be attached to the shaving foil.
  • the tubular receptacles are mounted in the walls of a shaving head frame which can be removed from the apparatus housing.
  • the tubular receptacles are part of a locking mechanism which fixes the shaving foil in the shaving head frame.
  • tubular receptacles of the pivotably arranged levers of the locking mechanism advantageously serve as a hinge axis for this purpose.
  • the tube-shaped receptacles of the shearing are - head associated with two functions, one being the function of the resilient support of the shaving foil and on the other the function of the mounting of the pivotable lever of the shaving foil defining Riegelgesperres.
  • the shaving foil 1 shows a basic illustration of the shaving foil holder according to the invention, which - as can be seen - is arranged here outside the space enclosed by the shaving foil 1.
  • the free ends 1.11 and 1.21 of the legs 1.1 and 1.2 of the shaving foil 1 are rolled outward in the manner of a spiral spring and have the effect of a roller spring, as is used, for example, in watch movements.
  • Central cutouts 1.12 and 1.22 in the film legs 1.1 and 1.2 serve for the penetration of coupling or connecting means of the shaving head, for example for its long hair trimmer, not shown.
  • the rolled ends 1.11 and 1.21 of the shaving foil 1 can be molded onto the shaving foil, i.e. be formed directly from the shaving foil material, but they can also consist of a different material than the shaving foil and can be attached to the shaving foil, as indicated at 1.23 in FIG. 1.
  • Tubular receptacles 2 which, as shown in FIG. 2, can be assigned to the shaving head of the dry shaving apparatus, for example formed on them, serve the leg ends 1.11 and 1.21 of the shaving foil 1 as a sleeve-like housing which accommodates each of the rolled-up leg ends with play.
  • the leg ends 1.11 and 1.21 can thus expand and contract spirally within the receptacle 2 and counteract the pressure load on the shaving foil which is exerted by the blade or knife block (FIG. 2) or the shaving pressure.
  • the shaving foil legs 1.1 and 1.2 into the receptacle 2 the latter is provided with a longitudinal slot 2.1.
  • Fig. 2 shows the shaving head 3 of the dry shaving apparatus, with a shaving head frame 5 which is removably arranged on the apparatus housing 4 and in the closed side walls 6 and 7 of which the tubular receptacles 2 for the shaving foil 1 are molded.
  • a cutter head 8 which is pressed against the shaving foil 1 in the usual way by a spring 9, shown here as a bellows spring.
  • the shear foil 1 is inserted into the receptacles 2 with its rolled ends 1.11 and 1.21.
  • FIG. 3 to 5 show the shaving foil holder according to the invention as part of a locking mechanism 10 which fixes the shaving foil 1 on the shaving head 3.
  • the shaving foil is denoted by 1, its free shackles by 1.1 and 1.2 and its spirally rolled leg ends by 1.11 and 1.21 .
  • the tubular receptacles 2 (FIG. 1) of the shaving head frame of the dry shaving apparatus, which envelop them with play, have here been designated 2.2 and 2.3 for the sake of clarity.
  • the two levers 10.1 and 10.2 of the locking mechanism 10 each pass through a corresponding section of the shaving head frame 5, the receptacles 2 simultaneously forming an articulated axis of the associated lever 10.1 or 10.2 of the locking mechanism 10.
  • This locking mechanism comprises - as mentioned - two double-armed levers 10.1 and 10.2 which can be pivoted about the articulation axis 2.2 or 2.3, the upper part of which serves as an operating handle and the lower part of which has an outwardly directed nose 10.3 or 10.4.
  • the lugs 10.3 and 10.4 and levers 10.1 and 10.2 engage under the side walls 5.1 and 5.2 of the shaving head frame 5 and thus fix the shaving foil 1 in a predetermined position on the shaving head frame 5 .
  • the lower ends of the levers 10.1 and 10.2 lie on the inside of a dome 4.1 of the apparatus housing and cannot be in this position be done.
  • the shaving head 3 is first lifted off the apparatus body 4, as shown in FIG. 4, and then the two double-armed levers 10.1 and 10.2 are spread apart, as a result of which the two lugs 10.3 and 10.4 are removed from the area of the two side walls 5.1 and 5.2 of the shaving head frame 5 swing out and thus the lock between the shaving foil 1 and the shaving head frame 5 is released.
  • the renewed insertion of the shaving foil 1 into the shaving head frame 5 takes place with the two double-armed levers 10.1 and 10.2 spread apart in the opposite manner.
  • FIGS. 3 and 4 shows a variant of the locking mechanism shown in FIGS. 3 and 4.
  • the tubular receptacles 2.2 and 2.3 and the double-armed levers 11.1 and 11.2 of the locking mechanism 11 are designed and arranged in the shaving head frame 5 such that their lugs 11.3 and 11.4 reach under the side walls 5.1 and 5.2 of the shaving head frame 5 from the outside.
  • This arrangement has the not insignificant advantage that in order to unlock the shaving foil from the shaving head frame 5, the upper sections of the two levers 11.1 and 11.2 need only be pressed inwards, that is to say against one another, in order to remove the lugs 11.3 and 11.4 from the region of the side walls 5.1 and 5.2 swing out the shaving head frame.
  • the rolled leg ends 1.11 and 1.21 of the shaving foil 1 surround two bearing rods 2.4 and 2.5, which serve as guide elements, the ends of which are rotatably mounted in or attached to the end cheeks 15 and 16 of the shaving head frame 5.
  • the rolled leg ends of the shaving foil 1 spring due to the envisaged roll spring property in accordance with the pressure acting on the shaving foil 1 or in accordance with the relief occurring after the action of pressure around the bearing rods 2.4 and 2.5.
  • four bearing bolts can also be provided on the end cheeks of the shaving head frame 5 as guide elements.
