Definitions

  • the invention relates to a long-hair cutter for dry shavers with a fixed, provided on a back with a bent flange shaving comb, a straight along this back and forth, by means of springs toothed shaving blade and attached to the flange, the abutment for the springs forming spring support.
  • the invention achieves this, starting from a known, special design of the shear blade, which has proven to be particularly advantageous (cf. DE-PS 33 03 989), by the means indicated in the characterizing part of claim 1.
  • the pre-assembly is limited in the long hair cutting device according to the invention on the insertion of the springs in the spring carrier and the final assembly on the insertion of the shear blade in the angle of the shear comb with subsequent buttoning of the spring carrier on the flange of the shear comb.
  • the spring supports with the associated angle levers are advantageously formed in one piece from plastic and the joint between the two components is designed as a film hinge.
  • the spring support is thus incurred during manufacture as a single component and does not need to be assembled in a separate assembly process, as is the case, for. B. in the device according to US-PS 41 18 863 the case.
  • the claims 6 and 7 characterize the advantageous design of the rear system of the shear blade in two places, namely on the flange of the shear comb and on the spring support such that they only on components of the long hair cutting device and not on external components such.
  • B. housing shells are related.
  • the long-hair cutting device shown in the drawing is, as shown in FIG. 1, basically constructed symmetrically to the center line A and consists of a shaving comb 1 which, for its stiffening behind the area of its teeth 2, initially at an obtuse angle upwards and then at right angles to a flange 3 - Related to the shear plane teeth 2 - is bent down, and from a shear blade 4, which has a thin blade 5, which is fixedly mounted on a support body 6 and forms a rigid unit with this.
  • the blade blade 5 is provided in its front area with teeth 7, which interact with the teeth 2 of the shaving comb 1, and on the back with tabs 8, which protrude through a cutout 9 in the flange 3, on the one hand rest on a shoulder 10 of the support body 6 and, on the other hand, are supported against a nose 11 on the upper edge of the cutout 9 in the flange 3.
  • the shear blade 4, which rests with play on the inner surface of the flange 3 with its rear edge in the sections next to the tabs 8 and lugs 10, is thus slidably guided in its front and rear area in the shear plane on the shear ridge 1 and secured against displacement both inwards transversely to its working movement and perpendicular to it.
  • the support body 6 of the shear blade 4 has a pocket 12 symmetrical to the center line A, in which the head of a drive lever (not shown in more detail) engages in the usual manner; In order to ensure its freedom of movement, a corresponding cutout 13 is made in the flange 3.
  • springs 14 are provided - the spring axes are denoted by a - which, combined in pairs, are accommodated on both sides of the center line of symmetry A in special spring supports 15 and are held in a cage-like manner by means of molded-on tabs 16 and abutments 17.
  • Buttons 18 are integrally formed on the spring supports 15, which reach through a correspondingly dimensioned narrower region 19 of the flange cutout 9, snap into place and lock the spring support 15 on the flange 3 in a positive and non-positive manner.
  • two angle levers 20 are provided on the spring support 15, each of which is pivotably articulated with a leg 21 via a film hinge 22 formed on the spring support 15 and with its free leg 28 abuts against the support body 6 in the region of the teeth 7 of the blade blade 5 or press against it.
  • the spring 14 assigned to each angle lever 20 causes a pivoting movement of the angle lever in a clockwise direction (FIG. 2), so that the spring pressure is translated as the contact pressure of the teeth 7 of the shaving blade 4 against the teeth 2 of the shaving comb 1.
  • Both angle levers 20 a spring support 15 are connected to each other by an elastic web 24.
  • a support 25 is formed on its side facing the flange 3, which projects in the same direction and parallel to the free legs 23 of the angle lever 20 between them upwards (FIG. 2) and is dimensioned such that its rear, through the cutout 9 in the flange 3 projecting surface 26 on the inner surface 27 of a pin 28 bent downwards (FIG. 2) of the extension 10 bears on the supporting body 6 of the shear blade 4.
  • the shear blade 4 is thus secured via its support body 6 on the spring support 15 against displacement transversely to its working movement also in the direction of the teeth 7.
  • the long hair trimmer is a self-contained, functional unit that is very narrow and can be pretested in a preassembled state. Because of its small space requirement, it can not only be permanently installed in the housing of a dry shaving apparatus, but also advantageously used in the case of a displaceable device with two flat housing shells 29 and 30 (FIG. 2).
