Definitions

  • the invention relates to a back and forth drivable bottom knife for dry shavers, which is intended to interact with a Siebscher film and has a number of spaced apart, arranged on at least one support, curved knife blades, at least the distances between one knife blade and the two neighboring ones Knife blades are not the same size.
  • Such a lower knife is known from JP-GM 49-2698.
  • the knife lamellae are arranged at different mutual distances, which are to change either block-wise or continuously.
  • the distances between the knife blades are mainly smaller in the middle area of the lower knife, because this area is mainly involved in shaving.
  • better cutting of the hair should be achieved, because in the area of the knife blades lying closer together, the holes in the screen shear foil are crossed more often by the knife blades and the areas with knife blades located further apart ensure that the screen shear foil comes into close contact maintained with the lower knife.
  • the distance between two knife blades should not be less than a certain amount, because otherwise the degree of coverage of the holes in the screen shaving foil by the knife blades will be too large, which means that the hair enters the Holes in the screen shaving foil are hindered and the shaving performance is reduced.
  • the invention has set itself the task of ver a lower knife of the type mentioned in terms of the shaving performance that can be achieved with it improve.
  • This object is achieved according to the invention in that the knife blades are grouped in pairs, at least in the apex region of the knife blades the distance between the two knife blades of a group is smaller than the distance between a knife blade of this group and the knife blade of an adjacent group lying next to it. In this way, the two knife blades of a group can interact due to their smaller distance from each other in the course of cutting a hair so that the hair in question is cut off particularly short.
  • the hair can enter the holes of the screening shear film unhindered in order to be subjected to a cutting process.
  • a very good shaving performance is obtained with such a lower knife.
  • the fact that the knife blades are grouped in pairs also means that the different spacing relationships between the knife blades are present in succession along the entire length of the lower knife, so that the entire lower knife, and not just an area of the same that has particularly good cutting behavior.
  • the knife slats grouped in pairs are flat and rigid in themselves.
  • Such knife slats are known per se; is essential to the invention that such Messerla m Ellen are grouped in pairs, wherein the distance between the two cutter lamellae of a group is smaller than the distances thereof from the adjacent groups of cutter lamellae.
  • the first knife blade of a group lying in front cuts off a hair once, a pull being exerted on the hair in question, forming a local cutting gap, so that it is pulled out of its skin pocket somewhat becomes.
  • the paired knife blades are designed to be elastically resilient in at least one of the two directions of the reciprocating drive movement for the lower knife, the front knife blade of each of the two knife blades of a group, viewed in each of the two directions of movement in its function resilient leading knife and the rear knife blade is effective as a stiff cutting knife in its function.
  • a leading knife is understood to mean a hair pulling element which pulls the hair out of its skin pocket before it is cut off by the subsequent cutting knife, as is the case for example in AT-PS 333.151, AT-PS 360.375 or also from US-PS 3,088,205 and DE-OS 2,850,827 emerges.
  • the pairing of the knife blades in a simple manner means that one blade blade of each group can act as a leading knife and the other knife blade as a cutting knife in both directions of movement of the lower knife, i.e. it pulls the leading blade blade on the hair and pulls it out pulls out his skin pocket and only the subsequent knife blade actually cuts the hair.
  • each of the two knife blades of a group in accordance with the inclination direction of its angled section, is effective in one of the two directions of movement of the lower knife as a functionally flexible leading knife and in the other direction of movement of the lower knife as a functionally rigid cutting knife.
  • each knife lamella is formed by two lamella sections angled in opposite directions. This makes it possible to arrange the two knife blades, each forming a group, on the carrier side at a somewhat greater distance, which can be advantageous with regard to their mounting on the carrier.
  • the angled lamella sections of the two knife lamellae forming a group lie in the apex region with prestress. This particularly favors a perfect interaction of the two knife blades forming a group in the course of a cutting process.
  • the self-cleaning with regard to adhering hair particles results from the knife lamella sliding smoothly against one another in the course of the cutting process.
  • the angled lamella sections lying in the apex area of the have a group of knife blades forming a group at their free ends.
  • a knife blade effective as a leading knife since it is not supported directly, is more resilient and bendable over a longer distance, which both favors the hair pulling effect.
  • the angled lamella sections in the apex region of the two knife lamellae forming a group each extend in a plane running perpendicular to the direction of movement of the lower knife. This makes it possible to utilize a larger circumferential area of the knife blades for the function as a leading knife.
  • each of the two knife blades of a group is supported in the direction of the reciprocating drive movement for the lower knife, in which it is intended to act as a cutting knife, which gives it such a rigidity that the cutting processes are particularly special run exactly and safely.
  • the desired elastic resilience of the knife blades can be achieved by appropriate choice of the hardness of their material and / or their thickness.
  • the carrier-side distance between a knife blade of a group and the knife blade of the adjacent group lying next to it is selected in the order of magnitude of twice the carrier-side distance between the knife blades of a group.
  • Fig. 1 shows a lower knife with flat, stiff, paired knife blades arranged in section transverse to the direction of the reciprocating drive movement along the line II in Fig. 2.
  • Fig. 2 shows the lower knife of Fig. 1 in a longitudinal section along the line II-II in Fig. 1.
  • Figs. 3a to 3d the sequence of movements when cutting a hair with a lower knife according to Figs. 1 and 2 is shown schematically.
  • Fig. 4 shows in the representation of Fig.1 and in section along the line IV-IV in Fig.
  • FIGS. 6a to 6c show the sequence of movements when cutting a hair with a lower knife according to FIGS. 4 and 5 .
  • Fig. 7 shows in longitudinal section a lower knife with flat, resilient knife blades, in addition to each of the two knife blades of a group, depending on the direction of the neighboring group, a rigid support is provided.
  • 8a and 8b schematically show the sequence of movements when cutting a hair with a lower knife shown in FIG. 7.
  • FIGS. 9a to 9f schematically show different exemplary embodiments of lower knives with knife blades, which are provided with different bends.
  • the lower knife shown in FIGS. 1 and 2 has two supports 1 and 2, which are formed by tubes and which carry curved knife blades 3.
  • the knife fins 3 are pushed onto the carriers 1 and 2 at a distance from one another with corresponding bores, their position on the carriers being able to be fixed, for example, in that the tubes forming the carriers are widened from the inside after the knife fins are pushed on.
  • the knife blades can be embedded in a carrier made of plastic.
  • Such a lower knife is used in a known manner to interact with a curved screen shear film having a plurality of holes, it being pressed resiliently into its curvature.
  • the lower knife is driven back and forth by the dry shaving apparatus, for which purpose it is provided with a coupling part, not shown, which can be fastened to the carriers 1 and 2, for example, by means of lugs extending between the knife lamellae.
  • Such a lower knife should be provided with as many knife blades as possible, since each knife blade forms a cutting edge in both directions of the reciprocating drive movement, the shaving performance of the dry shaving apparatus increasing the more cutting edges are provided.
  • the knife blades must not be arranged too close to one another, because otherwise they cover the holes provided in the sieve shaving foil, which serve to enter the hair, to such an extent that the hair is prevented from entering the holes Decrease in shaving performance.
  • the choice of the thickness of the knife lamellae is particularly important interpretation to.
  • the thickness of the knife blades is 0.1 mm and the distance between two adjacent knife blades is 1.15 mm.
  • Such a bottom knife can, for example, interact with a Siebscher film, the thickness of which is 0.05 mm and the holes have a diameter of 0.6 mm, the webs remaining between the holes having a width of 0.23 mm.
  • the knife blades 3 are grouped in pairs; 2, these groups are designated by 4. In the apex region of the knife blades indicated schematically in FIG. 1 by a dashed rectangle 5, the distance a between the two knife blades of a group 4 is smaller than the distance b between the knife blades facing one another of two adjacent groups 4.
  • the knife blades 3 here are flat and rigid in itself, as is known per se.
  • the thickness s of a knife blade 3 with 0.1 mm, the distance a between the two knife blades 3 of a group 4 with twice the thickness of a knife blade and the distance b between the knife blades 3 facing one another of two neighboring ones Groups 4 with three times the distance a can be selected.
  • FIG. 3a it can be seen how the hair 7 is clamped between the web 11 delimiting the hole 8 in the direction of movement 10 of the screen shear film 9 and the first knife blade 3 of a group 4 of two knife blades 3, also seen in the direction of movement 10, before it becomes Cutting process is coming.
  • Fig. 3b shows the beginning of the cutting process, in which a local cutting gap is formed in the area of this hole 8, with curvature of the sieve shear foil 9 in the direction of the skin 6, and slightly pulls the aforementioned first knife blade 3 on the hair 7, the latter being curved and something is pulled out of his skin pocket.
  • the first knife lamella 3 cuts off the hair end 12, as is indicated in FIG. 3c.
  • the paired arrangement of the knife blades in groups with a smaller distance between the two knife blades of a group and the sequence of the groups of knife blades with a greater distance means that on the one hand the two knife blades of a group cut the hair shorter and on the other hand the hair enters the holes in the screen shaving foil are not hindered, which is the case for the entire length of the lower knife, so that a very good shaving performance is obtained with such a lower knife.
  • the knife blades 3 are again arranged in pairs in groups 4.
  • knife blades are used which are designed to be elastically flexible in the two directions of the reciprocating drive movement for the lower knife, which can be done by the choice of their thickness and / or the hardness of the material used.
  • the individual knife blades are also provided with a recess 14 on the carrier side. The resilience of the knife blades ensures that of the two knife blades 3 of a group 4, viewed in each of the two directions of movement, the front knife blade as a so-called leading knife and the rear knife blade as a so-called cutting knife is effective, which will be discussed in more detail below.
  • the blade lamellae 3 are designed such that in the area of the two supports 1 and 2 they have lamella sections 15 which are parallel to one another and run transversely to the direction of movement of the lower knife and are used for mounting the blade lamellae on the two supports, to which lamella sections 16 are connected towards the apex region 5 which are angled relative to sections 15.
  • the knife blades 3 are mounted on the supports 1 and 2 in such a way that the bends of the two knife blades 3 of a group 4 formed by the sections 16 are directed towards one another in the apex region 5. With a view to a particularly good functioning, these bends are carried out in such a way that the sections 16 form an acute angle of the order of 10 with a plane 17 running perpendicular to the direction of movement of the lower knife, as can be seen in FIG. 5.
  • the arrangement of the knife blades 3 on the carriers 1 and? is further made such that the angled lamella sections 16 of the two knife lamellae 3 forming a group 4 lie in the apex region 5 with prestress.
  • the carrier-side distance c between the two knife blades 3 of a group 4 is selected to be smaller than the carrier-side distance d between the facing knife blades 3 of two adjacent groups 4. It has proven to be very favorable here if the distance c is of the order of five times the thickness s of a knife blade and the distance d in the order of twice the distance c is selected, the thickness s of a knife blade being 0.08 mm.
  • the knife fins which are punched out in an arc from a flat material are then provided with the bend formed by the finned section 16 and then in pairs, with bends directed towards each other, onto the tubes forming the supports 1 and 2 postponed and fixed on these with the corresponding distances c and d.
  • the circumferential surfaces of all knife blades are then subjected to a common grinding process, thereby ensuring that the screen shear foil fits snugly against the entire circumferential area of the knife blades.
  • FIGS. 6a to 6c show the state before a cutting process, in which a hair 7 has passed through a hole 8 in the screen shear film 9 and already between the web 11 of the screen shear film 9 delimiting this hole 8 in the direction of movement 10 and the first knife blade 3 also seen in the direction of movement 10 a group 4 of two knife blades 3 is clamped.
  • section 16 of this first knife lamella 3 hooks onto hair 7 and pulls on it, section 16 of this knife lamella being bent towards the second knife lamella 3 of this group 4 due to its elastic flexibility.
  • this knife lamella also being bent in the same direction due to its elastic compliance, with the result that its angled section 16 is erected and stretched substantially straight.
  • the screen shear film 9 is locally deformed and shifted in the direction of the skin 6.
  • Such a cutting process cuts a hair shorter than is normally possible.
  • Three factors are now relevant for this. The most important factor is that the first knife blade, which is moving in the direction of movement of the lower knife, pulls on the hair 7 before the actual cutting process, so that it is pulled out of its hair pocket a little and pulled further into the hole 8 of the screening shear film, resulting in a longer one Hair piece is available for the cutting process. Furthermore, an additional piece of hair 7 is pushed into the hole 8 of the sieve shear film by the local deformation of the sieve shear film 9 in the region of the hole 8, in which the film is pressed towards the skin, and is thus also subjected to the cutting process.
  • the blade blade 3 lying in front in the direction of movement of the lower blade in a group 4 of blade blades 3 is thus a functionally flexible leading blade and thus a hair pulling element and the blade blade 3 following in this direction of motion of the lower blade, which is only effective of the leading knife gains in stiffness, effective as a stiff cutting knife in its function.
  • the two knife lamellae 3 forming a group 4 of course only lie against one another with their angled sections 16 exactly at the apex. Starting from this apex, the distance between these two knife blades increases on both sides until the end of the bend on the support side is reached, after which the two knife blades with their sections 15 run parallel to one another at a distance c.
  • the result of this is that the mode of operation of the knife blades 3 as a leading knife and hair pulling element is essentially limited to the apex region 5 of the sections 16 of the knife blades, but this does not constitute a significant disadvantage.
  • the area mainly involved in a shave is, because of the usual handling of a dry shaver, the apex area, but where the desired functionality is guaranteed.
  • resilient knife blades 3 are used again, which are, however, of flat design here.
  • Two of these knife blades 3 each again form a group 4, the distance e between the two knife blades 3 of a group 4 being chosen smaller than the distance f between the knife blades 3 facing one another of two adjacent groups 4.
  • the thickness s of a knife blade is 0.08 mm
  • the distance e can be selected approximately equal to five times the thickness s and the distance f approximately equal to twice the distance e.
  • each of the two knife blades 3 of a group 4 in addition to each of the two knife blades 3 of a group 4, each in the direction of view of the group 4 adjacent to it, a stiff support 18 is provided, to which the knife blades 3 in question move when the Lower knife at least partially applied opposite to this line of sight.
  • each of the two knife blades 3 of a group 4 is resilient in the direction of the adjacent knife blade of the same group, whereas each of the two knife blades 3 of a group 4 is rigid in the direction of the group 4 adjacent to it, since the support adjacent to it 18 counteracts yielding in this direction.
  • the two knife blades 3 of a group 4 act as a leading knife forming a hair pulling element and the other time as a cutting knife.
  • the supports 18 are formed by strip-shaped parts which are provided with bores corresponding to the knife lamellae, so that, like the knife lamellae, they can be pushed onto the carrier of the lower knife formed by tubes, of which only the carrier 2 is visible in FIG. 7 are. After appropriate positioning of the knife blades 3 and the supports 18 with respect to their mutual positions, they are fixed on the carriers.
  • the rigidity that a knife blade receives when it is applied to the adjacent support can be determined by appropriate dimensioning of the support, for which the choice of material and shape are decisive.
  • such supports can also be designed differently, such as, for example, as spacers which are inserted between the knife blades.
  • FIGS. 8a and 8b The mode of operation of such a lower knife is illustrated with the aid of FIGS. 8a and 8b.
  • 8a again shows a hair 7 which has penetrated into a hole 8 of a sieve shear film 9 and which is already between the web 11 of the sieve shear film 9 delimiting this hole 8 in the direction of movement 10 of the lower knife and the first knife lamella 3 of a group 4 which also runs in this direction of movement is clamped by two knife blades 3.
  • the second knife lamella 3 then initiates the cutting process, since when viewed in this direction of movement, due to its contact with the support 18 adjacent to it, it is essentially stiff and thus acts as a cutting knife. In this way, longer pieces of hair are cut off than is known per se from the mode of operation of a leading knife.
  • a knife blade which acts as a leading knife is yielded over a distance determined by the distance e between the two knife blades 3 of a group 4, since the knife blade bends up to the knife blade which forms the cutting knife and follows it. In this way, there is a longer hair pulling area during which the leading knife pulls on the hair and pulls it out of the hair pocket, resulting in a shorter cut off of the hair.
  • such an operation of the two knife blades 3 forming a group 4 namely on the one hand as a lead knife and on the other hand as a cutting knife, will mainly occur in the apex region of the knife blades, since the blade blades are most flexible there.
  • the two knife blades 3 forming a group 4 are not in direct contact with one another in their starting position, the knife blade which is in each case effective as a leading blade can also give way in the circumferential direction of the apex area on both sides a little further away and accordingly act as a lead knife.
  • the two knife blades forming a group then act again as two rigid cutting knives, which come into effect shortly after one another, due to their increasing stiffness and their smaller spacing from one another, so that in these areas too, the hairs are cut off shorter takes place without the entry of hair into the holes of the sieve shaving foil being hindered because the distance between the facing knife blades of two adjacent groups of knife blades is again greater than the distance between the two knife blades of a group.
  • the two knife blades 3 of a group 4 in the apex area 5 are provided with a mutually directed angled portion which adjoins the blade portion 15 on the support side and is formed by a single blade portion 16, analogously to the exemplary embodiment according to FIGS. 4 and 5.
  • the angled lamella sections 16 face each other a plane 17 running perpendicular to the direction of movement of the lower knife has a greater inclination, which has the consequence that the carrier-side distances of the knife blades forming a group can be chosen to be larger, as a result of which the assembly of such a lower knife is facilitated.
  • FIG. 9a the two knife blades 3 of a group 4 in the apex area 5 are provided with a mutually directed angled portion which adjoins the blade portion 15 on the support side and is formed by a single blade portion 16, analogously to the exemplary embodiment according to FIGS. 4 and 5.
  • the angled lamella sections 16 face each other a plane 17 running perpendicular to the direction of movement of the lower knife
  • the exemplary embodiment according to FIG. 9b shows a similar arrangement to FIG. 9a, but the angled lamella sections 16 of the two knife lamellae 3 forming a group 4 lying in the apex region are at a distance h from one another at their free ends, which is analogous to the exemplary embodiment according to FIG. 7
  • What is achieved is that the area for the resilient adjustability of a knife blade effective as a leading knife is larger and thus the hair pulling effect is increased.
  • each knife lamella is formed by two sections 19 and 20 angled in opposite directions, the angled lamella sections 19 of the two knife lamellae 3 forming a group 4 in the apex region each having a point 17 with a plane 17 running perpendicular to the direction of movement of the lower knife Angles in sizes Form an order of 10 ° and rest against each other with pre-tension.
  • the sections 20 are then inclined correspondingly more with respect to the plane 17.
  • FIG. 9d shows an arrangement of the knife blades 3 analogous to FIG. 9c, but the angled blade sections 19 of the two knife blades 3 forming a group 4, which are located in the apex region, run with their free ends at a distance from one another, just as in the embodiment according to FIG. 9b.
  • the wiping relation of the knife lamellae is again formed by two lamella sections 19 and 20 angled in opposite directions, but here the lamella sections 19 of the two knife lamellae 3 forming a group 4 lie in the apex region each lie in a plane 17 running perpendicular to the direction of movement of the lower knife. Again, the lamella sections 19 rest against one another in the apex region with a pretension. Accordingly, the two mutually parallel lamella sections 19 of the two knife lamellae 3 forming a group 4 adjoin one another flatly.
  • a knife lamella 3 When a knife lamella 3 functions as a leading knife, its section 19 then moves along the section 19 of the other knife lamella 3 of the relevant group 4 of knife lamellae 3, which acts as a cutting knife.
  • the functional area for a leading knife then extends over the entire circumferential area of the sections 19, although only a smaller adjustment path is obtained for the knife blade which acts as a leading knife.
  • An enlargement of this adjustment path for the knife blade acting as the leading knife can be obtained again if the angled sections 19 of the two knife plates 3 forming a group 4 run at a distance h from one another, as is shown by the exemplary embodiment according to FIG. 9f.
