Definitions

  • the invention relates to a dry shaving apparatus with at least one sieve shear part and at least one comb shear part, in which the upper knife of the sliding shear part, which is designed as a curved flexible sieve shear film, forms an upper knife unit with the upper knife of the comb shear part, in which the comb shear part with an effective part directly on the effective part of the sieve shear part connects on the longitudinal side, and a lower knife unit cooperating with this upper knife unit is provided, which has a back and forth driven carrier for holding and driving the lower knife of the shear parts.
  • Such a dry shaver is known from AT-PS 292 502.
  • This known dry shaving apparatus has a sieve shear part and two comb shear parts, the comb shear parts with their effective parts each directly adjoining one of the two long sides of the active part of the sieve shear part in the course of its curvature.
  • the upper knife unit is formed in one piece and consists of a single metal foil, which has a perforated area in its central part to form the upper knife for the screen shear part and is provided on both longitudinal sides with a bending edge, in the area of which shear comb slots form the upper knife for the two Comb shear parts are provided.
  • the two lower knives of the comb shear parts are formed by a metal foil, which is provided on each angled side edge with a row of slots, which form the shear combs of the lower knives, which then interact with the shear comb slots on the sieve shear foil. It has been shown that comb shaving parts designed in this way do not result in satisfactory cutting behavior for longer hair, because the metal foils forming the upper knife and the lower knife have insufficient rigidity. This is in contrast to the sieve shear part, where a sieve shear film has proven its worth, especially for training as an upper knife, because here the flexibility of the sieve shear film ensures that the lower knife fits snugly.
  • the bottom cutters of the comb shear parts are designed as flexible metal foils has not proven to be sufficient for the associated upper cutters to result in a correspondingly high cutting pressure, which also reduces the cutting effect.
  • the comb shear parts are provided in the area of the longitudinally angled edges of the sieve shear film, the effective parts of the comb shear parts directly adjoin the active part of the sieve shear part, but lie in the course of the curvature of the sieve shear film, which has the consequence that the two different shaving systems, namely the sieve shear system and on the other hand one of the two comb shaving systems, cannot be used at the same time, since a certain inclination of the dry shaving apparatus is required in order to bring one of the two comb shaving parts into effect.
  • the possibility of using such different shaving systems at the same time has proven to be very advantageous in terms of increasing the shaving performance because longer and shorter hairs are then cut at the same time.
  • the upper knife and the lower knife of a comb shear part By combining these three features, it is possible to design the upper knife and the lower knife of a comb shear part to be stiff and to press them strongly against each other by their own spring, so that such a comb shear part has good cutting properties for longer hair, furthermore an upper knife unit and to form a lower knife unit, which results in a particularly simple construction, manufacture and assembly, and finally to arrange the comb shear part opposite the sieve shear part in such a way that their effective parts connect to one another in such a way that both shear systems can be used at the same time, which means that longer cuts can be made simultaneously and shorter hair shortens the shaving time and thus increases the overall shaving performance.
  • feature a) is known per se from DE-PS 938 475, but the comb shear parts as a whole protrude laterally and practically at right angles Connect the effective part of the sieve shear foil, whereby the effective parts of these comb shear parts lie in planes that run approximately parallel to the relevant tangential plane to the effective part of the sieve shear part in the connection area of the shear parts, which means that a simultaneous use of both shear systems is not suitable Way is possible.
  • feature b) is known per se from DE-AS 1 553 713, but where the two shear systems are formed as separate parts and therefore there is a more complicated overall structure.
  • feature c) is known per se from GB-PS 628 599, but according to which only a plurality of comb shear parts are provided. However, it is precisely the combination of the three different features which, when used in a dry shaving apparatus of the type mentioned at the outset, gives all of the advantages mentioned above.
  • an angled strip can be provided, for example, on a side wall of the channel-shaped part, to which the screen shear film is attached with its edge zone. It has proven to be very advantageous, however, if the upper knife of the comb shear part is connected directly to a side wall of its channel-shaped part with a longitudinally extending edge strip of the screen shear film which is angled towards the lower knife unit. In this way, the transition from the effective part of the screen shear part to the effective part of the comb shear part can take place within a relatively narrow range, which is very favorable for the simultaneous use of both shear systems.
  • the angled edge strip of the screen shear film connected to the side wall of the channel-shaped part extends in the region of a bevel provided on the bottom knife of the screen shear part. This makes it possible to limit the transition from the effective part of the screen shear part to the effective part of the comb shear part to an even narrower range.
  • the upper knife unit can be completely released from the lower knife unit in the region of the angled edge strip of the screen shear film connected to the side wall of the channel-shaped part.
  • the lower knife unit has a guide surface which interacts with the upper knife unit in the region of the angled edge strip of the screen shear film connected to the side wall of the channel-shaped part. In this way, between the mentioned area of the upper knife unit and the guide surface on the lower knife unit, a sliding support is formed when the lower knife unit is driven, which results in very advantageous guidance for the lower knife in the immediate vicinity of the upper knife unit, which has a favorable effect on the cutting behavior of the shear parts.
  • the slots provided in the top knife of the comb shear part as hair entry openings extend into the side wall of the channel-shaped part of the top knife of the comb shear part facing away from the screen shear film.
  • a comb with long hair entry openings is formed in this way, which greatly encourages the catching of longer hair.
  • the special arrangement of the spring acting on the support of the lower knife unit ensures that for the interaction of the lower knife unit with the upper knife unit, the known stability condition that the sum of all forces and the sum of all moments is zero is fulfilled in such a way that none additional frictional forces occur on supports, which naturally has a generally favorable effect, but in particular has a favorable effect on the overall cutting behavior.
  • the invention relates to an upper knife unit for a dry shaving apparatus according to the invention.
  • such an upper knife unit is characterized in that a sieve shear film forming an upper knife for a sieve shear part has an angled edge strip in the area of at least one of its two edge zones running in the longitudinal direction, with which a side wall of a channel-shaped, rigid part which forms an upper knife for a comb shear part is firmly connected.
  • a structural unit which is very simple and also very easy to produce is obtained, which can be handled just as easily as a Siebscher film by itself, as a result of which such an upper knife unit is particularly well suited as a spare part.
  • the combined upper knives of the screen shear part and of the comb shear part can each be designed in such a way that they have optimum properties for the shear system in question. Furthermore, by connecting an angled edge strip of the screen shear film directly to a side wall of the channel-shaped part, the effective parts of the upper knives connect very closely to one another and as little space as possible that is useful for cutting purposes is lost.
  • the angled edge strip of the screen shear film can be connected to the side wall of the channel-shaped part in a wide variety of ways, for example by welding, riveting or clamping.
  • FIG. 1 shows the parts of a sieve shear part and a dry shaving apparatus which adjoins this on the longitudinal side and are essential to the invention, in section transverse to the reciprocating drive movement for the lower knife unit.

  • Fig. 1 denotes a first housing shell and 2 denotes a second housing shell of a dry shaving apparatus, which receive the drive part for the dry shaving apparatus.
  • rocking lever 3 is shown here, which is pivotably mounted between the housing shells 1 and 2 by means of a shaft 4.
  • This rocker arm 3 can, for example, be a direct component of a rocker arm motor or be driven back and forth by an eccentric seated on a rotatingly driven motor shaft.
  • the rocker arm 3 has a free end 5, from which, for example, the reciprocating drive movement can be removed.
  • Such a long-hair trimmer has a plate-shaped upper knife 8, which is provided along one side edge with cutting teeth 7, and a correspondingly arranged, also plate-shaped upper knife 8, which is provided along a side edge with cutting teeth 9 and can be driven back and forth.
  • the lower knife 10 is pressed against the upper knife 8 by means of two springs, one spring 11 of which is visible in FIG. 1, and is guided so that it can be moved back and forth via pin-slot connections 12.
  • this is provided with a coupling arm 13, which has a slot 14 at its free end, into which a further rocking lever 15 engages, which in turn projects with a shoulder 16 into a slot 17 of a coupling projection 18 provided on the rocking lever 3.
  • the further rocker arm 15 can be pivoted, for example, on the housing shell 2 and is also displaceably mounted in its longitudinal direction (which is not shown here), so that by adjusting this rocker arm 15 in the direction of the double arrow 19, which can be done by means of a suitable operating element, the drive connection between the lower knife 10 and the rocker arm 3 can be lifted or, as shown in Fig. 1, manufactured.
  • This long hair cutter 6 is an additional cutting element, as is often provided in dry shavers, and is used, for example, for shaping hair roots.
  • the shaving head of the dry shaver used for shaving points In the present exemplary embodiment, a sieve shear part 20 and a comb shear part 21 adjoining this on the longitudinal side, of which the sieve shear part serves to cut shorter hair and the comb shear part serves to cut longer hair.
  • the upper knife of the sieve shear part consists of a relatively thin, curved, flexible sieve shear film 22, which has in its effective part a hole field forming the hair entry openings, whereas the upper knife of the comb shear part is designed as a channel-shaped, inherently rigid part 23, which is effective in its own part Partly has slits as hair entry openings and is made of somewhat thicker material so that, apart from the shape, it receives the required rigidity.
  • the bottom knife 24 cooperating with the screen shear foil 22 is arcuate and is listed in the present exemplary embodiment as a so-called tubular lamella knife.
  • knife fins 27 are lined up on two tubes 25 and 26 at a distance from one another.
  • a lower knife can also be designed differently within the framework of the embodiments known for this purpose, such as, for example, as a curved sieve shear film.

  • the free ends of the cutting teeth interact with the region of the channel-shaped part 23 which forms the upper knife of the comb shear part and which has the hair entry openings.
  • this lower knife such as a Windke profile or T-profile.
  • both shaving systems namely the sieve shear part and the comb shear part, can each be optimally dimensioned so that they cut shorter hair on the one hand and longer hair on the other hand. It has also proven to be advantageous if these two shaving systems are arranged in such a way that they can also be used at the same time, as a result of which longer and shorter hair is cut off during shaving and can therefore be shaved very thoroughly in a shorter time.
  • the comb shear part 21 with an effective part directly adjoins the effective part of the sieve shear part 20 on the longitudinal side, in such a way that this effective part of the comb shear part protrudes laterally, with the two shear parts 20, 21 connecting to one another the plane defined by this effective part of the comb shear part 21 forms an obtuse angle with the tangential plane to the active part of the screen shear part 20, as can be seen in FIG.

  • the line 30 indicating the plane defined by the effective part of the comb shear part 21 and the line 31 indicating the tangential plane to the active part of the screen shear part 20 in the connection region of the two shear parts.
  • How large the obtuse angle spanned by the two planes 30 and 31 is chosen depends entirely on the proviso that both shear systems should be able to be used at the same time with the best possible and full utilization of their effective parts, a decisive factor being how strong the Sieve shear part 20 is curved, that is how large its arrow height is. In the case of a very flat curvature of the sieve shear part, the obtuse angle will come relatively close to 180 °, whereas it will be considerably smaller if the sieve shear part is strongly arched.
  • the effective part of the comb shear part 21 connects as directly as possible to the effective part of the sieve shear part 20.
  • the trough-shaped part 23 forming the upper knife of the comb shear part 21 is firmly connected to the sieve shear film 22 forming the upper knife of the sieve shear part 20 and that both upper knives thus form an upper knife unit.

As can be seen, these slots 46 connect practically directly to the perforated field 40 in the screen shear foil 22, so that the two heavy systems 20, 21 can be used particularly effectively at the same time in such an upper knife unit 22, 23.
