Definitions

  • the invention relates to a dry shaving apparatus with a resiliently pressed against a curved sieve shear foil, driven by a pivotable about an axis, cranked with respect to its oscillation level oscillating back and forth driven lower knife, which is transverse to the vibration level of the output-side end of the oscillating lever extending axis is pivotally connected to a driver, which in turn is arranged on the driven end of the rocker arm, in the longitudinal direction of this end and pivotable relative to the same.
  • a dry shaver is disclosed in the exemplary embodiment according to FIG. 7 of DE-OS 21 02 968.
  • the driver is formed by a ball which has two diametrically opposite end pieces.
  • the ball and the end pieces are penetrated by a hole into which a driver pin is inserted, which is connected at its two ends to the lower knife, so that the axis of the driver pin forms the axis about which the lower knife is pivotable on the driver, in which In the present case, this axis runs perpendicular to the output-side end of the rocker arm.
  • the ball is inserted into a bore provided in the longitudinal direction of the rocker arm at the output end of a rocker arm which can be pivoted about an axis, its projections protruding from the drive end of the rocker arm through slots lying on the side of the bore.
  • the rocker arm itself is cranked with respect to its plane of vibration so that a shaving head frame carrying the screen shaving foil can be arranged laterally from the dry shaver, which is often desirable in order to facilitate the handling of the dry shaver when shaving.
  • the axes, around which the rocker arm and the lower knife on the driver are pivotable enclose an acute angle, which means that the lower knife strives to describe a path in the manner of a cone shell in the course of its entire reciprocating movement and therefore does not perform any linear movement on its own.
  • the driver for the lower knife is designed as a ball, it can be adjusted relative to the output-side end of the rocker arm in all three possible degrees of freedom, so that the driver and the lower knife connected to it can be pivoted or tumbled on all sides at the output-side end of the rocker arm lever is arranged, whereby the lower knife in cooperation with the screen shear film is guided straight from this. In this way, it should be achieved that even under the action of a shaving pressure on the screen shear film, a perfect interaction of the lower knife with the screen shear film is guaranteed.
  • the invention has set itself the goal of eliminating the aforementioned difficulties and to provide a drive system for the bedknife in a dry shaver of the type mentioned, with which a good shaving performance of the dry shaver is actually obtained with little noise.
  • the axis, about which the lower knife is pivotally connected to the driver runs parallel to the axis about which the cranked rocker arm ver is pivotable.
  • the invention relates exclusively to dry shavers in which a cranked crank arm is used.
  • a dry shaving apparatus with a rocker arm that is not cranked with respect to its vibration level as they are widely known, see for example DE-AS 1 162 719, it is obvious that the axis about which the lower knife is pivotally connected to the driver is parallel to the axis about which the rocker arm is pivotable.
  • the undercutter therefore carries out a straight-line oscillating movement without additional measures, so that there is no problem with such dry shavers, as occurs in connection with a crank lever which is configured cranked.
  • FIG. 1 shows, partly in section and in side view, a dry shaver with a cranked crank arm for driving a bottom cooperating with a screen shaving foil knife.
  • 1 denotes the basic apparatus of a dry shaving apparatus composed of two housing shells 2 and 3, onto which a shaving head frame 4 can be placed, which carries an arched screen shaving foil 5.
  • the two longitudinal edges of the screen shaving foil 5 are provided with strips 6 and 7, which have openings into which pins 8 and 9 provided on the shaving head frame 4 engage.
  • a back and forth drivable bottom knife 10 which in the present case is designed as a lamellar knife, the individual knife blades 11 of which are curved in line with the course of the screen shear film 5 and arranged one behind the other on two tubular spacers 12 and 13 are.
  • This lower knife 10 is in turn arranged on a lower knife carrier 14, for example in that the tubular spacers 12 and 13 are snapped onto two locking projections 15 projecting from the lower knife carrier 14, one behind the other, each projecting between two adjacent knife blades.
  • a drive device 16 is accommodated in the basic apparatus 1, which has a pivotably mounted rocking lever 17, the end 18 of which on the driven side protrudes from the basic apparatus 1 in the direction of the lower knife 10.
  • this rocker arm can be a direct component of a rocker armature motor which is designed in a conventional manner and is not shown here, so that the rocker arm immediately executes a pivoting movement.
  • the rocker arm 17 could also be drivable, for example, from an eccentric, which in turn is seated on a shaft of an electric motor that performs a rotating movement.
  • the rocker arm 17 is provided with a bearing bush 19 with which it is placed on an axle journal 20, which is held at its two ends on the one hand by a mounting frame 21 and on the other hand by an end plate 22 which can be connected to the mounting frame 21, the Mounting frame 21 in a manner not shown here, for example on the housing scha le 3 is attached.
  • the rocker arm 17 is thus pivotable about an axis 23 of the journal 20 shown by a solid line.
  • a driver 24 which is arranged on the output-side end 18 of the rocker arm 17 in the longitudinal direction of this end 18 and is pivotable relative to the same.
  • this driver 24 is formed by two hollow cylindrical sections 26 and 27 which are connected to one another by a bridge 25 and run coaxially with one another, of which section 26 is placed as a guide part on the cylindrically shaped end 18 of the rocking lever 17.
  • two diametrically opposite pin-shaped projections 28 are further provided in the area of the driver 24, each of which protrudes into one of two likewise diametrically opposite recesses 29, which are provided in section 27 of the driver 24.
  • the lower knife carrier 14 and with it the lower knife 10 are arranged pivotably on the driver 24, the axis 33, which is indicated by a solid line and defined by the stub axles 31 and 32, forms the pivot axis for the lower knife carrier 14. Furthermore, between the driver 24 and the rocker arm 17, a compression spring 34 is effective, which is supported with its ends on the one hand on the driver 24 and on the other hand on the rocker arm 17, as can be seen from the figure. In this way, the lower knife 10 fe by the spring 34 dernd pressed into the curved sieve shear film 5, whereby the knife blades 11 of the lower knife 10 lie snugly against the sieve shear film and thus result in a perfect interaction of the lower knife 10 with the sieve shear film 5.
  • Such resilient pressing of the lower knife 10 against the screen shear film 5 could of course also be achieved in a different way, for example, as is known in that instead of a compression spring 34 two compression springs are provided, which are on the one hand on the lower knife carrier 14 and on the other hand on the housing shells 2 and 3 support. Due to the mentioned pivotable arrangement of the lower knife carrier 14 on the driver 24 and its longitudinally displaceable and pivotable arrangement on the driven end 18 of the rocker arm 17, adaptation options of the lower knife 10 to the screen shaving foil 5 are created in a known manner, which also during operation of the dry shaving apparatus under the influence of a Shaving pressure on the screen shaving foil, ensure a perfect interaction of the lower knife 10 with the screen shaving foil 5. It should also be mentioned that between the section 27 of the driver 24 and the housing shells 2 and 3 an elastically resilient part 35 is arranged, which forms a hair dust seal to the basic apparatus 1 in the usual way.
  • the shaving head frame 4 carrying the sieve shaving foil 5 is arranged to protrude laterally from the base apparatus 1 of the dry shaving apparatus, as can be seen from the figure, which results in more convenient handling of the dry shaving apparatus when shaving.
  • the rocker arm 17 is cranked with respect to its plane of vibration in that its output-side end 18 is inclined with respect to its portion 36 mounted on the journal 20, in which case the plane of oscillation of the output-side end 18 of the rocker arm 17 indicated by the broken line 30 is blunt Forms an angle with the vibration plane of the section 36 of the rocker arm 17 indicated by a dashed line 37.
  • the axis 33 to the the lower knife carrier 14 and with it the lower knife 10 is pivotally connected to the driver 24, runs parallel to the axis 23 about which the rocker arm 17 is pivotable.
  • the stub axles 31 and 32 provided on the driver 24 are not arranged to run perpendicular to the output end 18 of the rocking lever 17, as in the known prior art, but rather are inclined so that they run parallel to the journal 20 about which the rocking lever 17 can be pivoted .
