Definitions

the invention relates to a hair removal device with a clamping device for pulling in and pulling out hair from a skin surface.
a motor-driven depilation device is also known in which a tightly wound coil spring with a curved axis is rolled on the skin surface.
V-shaped gaps arise between the individual spring windings, which are used first to pull in the hair and then to clamp it.
part of the hair is sheared or squeezed off here, which is obviously due to the sliding process between the spring coils and the hair. The procedure must therefore be repeated several times and at longer intervals.
the invention is therefore based on the object of specifying a hair removal device of the type described at the outset with which reliable hair removal can be carried out already during the first application and while avoiding pain.
the hair is drawn between the slats either individually or in pairs.
the clamping position is now maintained during the retraction movement of the tweezer block over at least part of the retraction path, and only in the area of the point of reversal of the tweezer block at a point distant from the support device are the lamellae moved back into the spread position, so that the hair, meanwhile torn out with the root can be ejected.
Mass forces play a significant role in both the pull-in movement and the ejection movement, so that all oscillating movements should be carried out with a corresponding frequency which is significantly higher than 1000 min ⁇ 1 and preferably should be between 2000 and about 15,000 min ⁇ 1.
the design of the tweezers system according to feature b) is of particular importance.
the clamping heads can be expanded by a limited amount. It does not matter whether there is at least one In between there is no hair, just one hair or even several hairs.
a clamping device which will be explained in more detail below, the inherent elasticity of the system and / or an articulated bearing leads to a compensation. This is especially true when using a tweezer block consisting of numerous lamellae according to claim 3. Since the spaces between the individual lamellae are "connected in series", the clamping forces in all spaces are essentially the same size, so that a reliable clamping of all detected hair is guaranteed.
the clamp is produced, there is practically no relative movement between the hair and the lamellae, so that grinding or squeezing of the hair is reliably avoided.
a particularly advantageous embodiment of the hair removal device according to the invention is characterized by a first and a second bearing for the tweezers system, of which the first bearing an oscillating longitudinal displacement of the tweezers system in the direction of an axis of symmetry S1-S1 and the second bearing of an oscillating pivoting movement of the tweezers block about an axis of symmetry vertical and parallel to the spreading direction of the slats axis A1-A1.
the tweezer block Due to the oscillating longitudinal displacement, the tweezer block is moved towards the surface of the skin when the lamella is in a spread state and, after the clamping has been brought about, the hair is pulled away from the surface of the skin.
This movement is superimposed on the oscillating pivoting movement of the tweezer block, with the procedure being particularly particularly advantageous in such a way that the tweezer block generates a comb-like movement essentially parallel to the skin surface, at least when its approach to the skin surface has ended when the lamellae are in a spread position, so that they frequently very tangled hair is to a certain extent brushed into the spaces between the lamellae.
the desired pulling out of the pinched hair can be brought about in the retracting movement of the tweezer block.
the hair is drawn between the lamellae by the relative movement of the hair removal device supported against the skin in the feed direction. In operation, the hair removal device is guided over the skin surface to be depilated like a dry shaver.
a again particularly advantageous hair removal device is characterized by a drive device with at least three control functions for - the oscillating spreading and clamping of the slats, - The oscillating longitudinal displacement of the slats, and - The oscillating pivoting movement of the lamellae and with such a correlation of the control functions that the lamellae are spreadable at the latest when they approach the surface of the skin and in a spread state with their free ends parallel to the direction of advance and to the skin surface that the lamellae are pivotable at the end of this pivoting movement can be put into the clamped state and can be withdrawn from the skin surface in this state and that the slats can be put into an opposite pivoting movement at the latest at the end of their retraction movement and can be put back into the spreading state at the latest at the end of this pivoting movement.
clamping jaws are preferably arranged on their free ends on both sides of the slat block, the opening and closing movement of which can be controlled by a crank mechanism.
the clamping jaws are parts of two mirror-symmetrically arranged angle levers, the legs of which are directed towards one another and are connected to a crank rod which runs essentially parallel to the axis of symmetry of the tweezers block and is connected with its end remote from the angle levers to a driven crank.
the tweezer block is expediently guided in a tweezer frame which surrounds the entirety of the lamellae with a play sufficient for their spreading and is pivotally mounted with the lamellae on the axis A1-A1.
the tweezers block can then be pivoted either with or without the tweezers frame, but preferably with the tweezers frame, in a tweezers carriage which is arranged on a parallel guide which is stationary relative to the housing.
the correlation of the movement of the tweezers slide on the one hand and the clamping jaws for the tweezers block on the other hand can take place in a mechanically defined form by means of a rigid coupling, namely, for example, by driving the tweezers slide by means of a cam disk which can be rotated synchronously with the crank of the crank mechanism for the movement of the clamping jaws is.
the cam plate and the crank are arranged particularly coaxially on a common drive shaft.
mechanical positive control can also be replaced by a play of mass and spring forces, whereby not only the construction effort but also the driving forces are reduced, since the springs required for such a system act as an energy store the relaxation of the springs restores at least part of the energy applied during the tensioning process recovered.
Such a system is characterized according to the further invention in that the tweezers slide in the direction of the support device under the action of at least one spring, by which it is displaceable up to a further stop, that the crank rod at the connection point with the angle levers with a sliding block is provided, which engages with a limited stroke in a slide guide, which in turn is attached to the tweezers slide, and that the design of the spring and the path limitation of the sliding block in the slide guide are made such that the opening movement of the clamping lacquers arranged on the angle levers before the stopping of the Tweezer carriage is terminated at the further stop, and that the closing movement of the clamping jaws is initiated after the tweezers block with spread slats has arrived in the vicinity of the support device.
the design of the spring and the mass of all the parts moving with the tweezers slide are given at a given operating frequency so that the sliding block pushes the tweezers slide against the front end of the slide guide when the jaws are open, so that the tweezers block moves in front of the tweezers slide is closed via the angle lever by means of the sliding block after its passage through the front dead center, and that the sliding block in its retraction movement on the reaction force of the clamping jaws stops the rear end of the sliding block guide relative to the sliding block guide and pulls the tweezers sled away from the support device when the clamping jaws are closed, whereupon the tweezers block is opened again after briefly continuing its retraction movement by means of the sliding block after it has passed through the rear dead center.
the movement correlation between the tweezers slide on the one hand and the clamping jaws on the other hand can be attributed to the structural union of the mounting of the angle lever with the tweezers slide described above.
the construction instructions described above can be expressed in a simplified manner in such a way that the spring or springs acting on the tweezers slide are so weak that the tweezers slide lags the sliding block and thus the parts driven by the crank mechanism so as to be out of phase. Only in the periods in which the sliding block rests either on one or the other end of the sliding guide does the sliding block and the tweezers slide move in exactly the same direction and speed. It then only depends on the so-called "dead gear" of the sliding block in the sliding guide and on the path limitation of the tweezers slide, to what extent the tweezers slide with forced control of the slats, the sliding block and so that the crank mechanism can lag behind for a limited time.
the design of the spring or springs already described is essential. Knowing the relationships, however, the determination of the spring characteristic is a measure which is relatively easy to carry out by a person skilled in the art.
the characteristics of the leaf springs that are preferably used can be determined solely by the choice of length, curvature and section modulus. However, these possibilities of influence are familiar to the person skilled in the art, so that further explanations can be dispensed with.
FIG. 1 shows a hair removal device 1 which has a housing 2 with a lower housing part 3, a cover 4, a switch 5 and a housing extension 6. On the underside of the lower housing part 3 there is a plug device 7, which is shown in FIG. 2 and is used for the insertion of an electrical lead.
the housing attachment 6 has in its front face 8 a feed opening 9 which is filled with a support device 10 which consists of a row arrangement of thin, U-shaped sheet metal strips which leave relatively narrow gaps between them for the introduction of the hair to be removed.
the support device 10 serves to place and move the device on the surface of the skin, as is customary with dry razors.
the direction of feed to be used here is indicated by the arrow 11.
the gaps within the support device 10 run parallel to this feed direction.
On the top of the support device there is also a strip-shaped brush which has been left out for the sake of clarity and which serves to straighten the hair and to facilitate insertion into the gaps.
FIG. 2 shows a chassis 12 made of plastic, to which the plug device 7 is also molded.
An electric motor 13 is structurally connected to the chassis 12, as is known from motor-driven dry shavers. Due to the increased power requirement, a 50 to 100% larger design is recommended.
the stator winding of the electric motor 13 is designated 13a.
This gearwheel is fastened together with a cam disk 16 and a crank with crank pin 17 on a further axis of rotation.
a so-called eccentric can also take the place of the crank pin 17.
the axis of rotation runs parallel to the motor axis.
crank pin 17 is in turn surrounded by a bearing ring 18 which engages in a slide 19 with the least possible play.
This slide is connected to a crank rod 20, the free end of which is connected in a mirror-symmetrical arrangement to two angle levers 21 and 22 which are extended downwards on their lever arms on the other side by clamping jaws 23 and 24.
the angle levers 21 and 22 are pivotally mounted on axes 25 and 26, the fastening location of which will be discussed in more detail below. It can be seen that a retraction of the crank rod 20 causes the clamping jaws to be pressed together and an advance of the crank rod 20 causes the clamping jaws 23 and 24 to spread.
the chassis 12 has a parallel guide 27 on its upper side, which consists of two metallic, parallel guide pins 27a and 27b.
a tweezer slide 28 is guided on these guide pins, on the upper side of which a guide sleeve 29 for the crank rod 20 is firmly attached.
a tweezer frame 30 is now pivotally mounted in the tweezers slide 28, the pivot axis 31 running perpendicular to the guide pins 27a and 27b and to the axes 25 and 26. With reference to FIGS. 4 and 5, the pivot axis 31 runs parallel to the plane of the drawing.
a tweezer system P here designed as a tweezer block 32, is in turn mounted on the same pivot axis 31, which consists of individual lamellae 33 which can be spread and compressed relative to one another. Details of the Tweezer systems are explained in more detail with reference to Figure 6.
the tweezers slide 28 carries at its front end the axes 25 and 26 for the angle levers 21 and 22, so that these axes can be moved together with the tweezers slide.
the speed and direction of movement of the tweezers carriage 28 are determined by the angular speed and the course of the cam disk 16, which acts on the tweezers carriage via a roller that is not visible here.
the correlation of the curve of the cam disk 16 and the relative angular position of the crank pin 17 results in a positive coupling between the movement of the tweezers slide 28 and the clamping jaws 23 and 24 in the sense shown above.
the free ends of the tweezers block 32 are located between the jaws 23 and 24, as can be seen particularly clearly from FIGS. 2 and 3. It can thereby be achieved that, during the oscillating linear movement of the tweezers slide 28, the tweezers block 32 can perform a spreading or clamping movement in certain areas of this linear movement, the plane in which this clamping or spreading movement takes place running through all the lamellae of the tweezers block 32 . In relation to FIGS. 4 and 5, the plane of the spreading movement again runs parallel to the plane of the drawing.
the tweezer frame is provided on its upper side with pivot levers 33 which, after a partial stroke of the tweezers slide 28, abut a stop 34 which consists of a wire bracket. This forces the tweezer frame 30 and with it the tweezer block 32 to perform an upward tilting movement about the pivot axis 31. It is understood that this tilting movement is carried out before the clamping jaws 23 and 24 press the tweezer block 32 together.
FIG. 4 the crank rod 20 leads the movement of the tweezers slide 28 by a small amount, and the clamping jaws 23 and 24 are at such a distance that the individual lamellae of the tweezers block 32 are in the spread position.
the tweezers block 32 is in its lowest position relative to the clamping jaws 23 and 24.
the stable position of this lowest position is brought about by a compression spring which - not visible here - is arranged between the tweezers slide 28 and the tweezers frame 30. This spring lies under the guide sleeve 29.
the crank pin 17 is already advanced by such an angle of rotation that the crank rod 20 has carried out part of its total retraction movement and the entire relative retraction movement with respect to the tweezers slide 28.
the free legs 21a and 22a of the angle levers 21 and 22 were pulled backwards and the clamping jaws 23 and 24 moved toward one another while clamping the lamellae 35.
the hairs located between the lamellae are extremely reliably clamped in this way and are reliably torn out during the further retraction movement, which is triggered by the rotation of the cam disk 16 and the crank pin 17 in the same direction.
FIG. 6 shows the tweezer block 32 with the fins 35 and their free ends 35a on an enlarged scale and with an excessive spread.
the points of action of the jaws 23 and 24 are indicated by the arrows 23 ⁇ and 24 ⁇ .
the plane in which the spreading or clamping takes place runs parallel to the plane of the drawing, and lies in this plane also the pivot axis 31, defined by the geometric axis A1-A1.
the tweezer frame 30, which is also mounted on the pivot axis 31, has also been omitted for the sake of simplicity.
the individual lamellae 35 have an upright cross section with flat sides 35b and 35c which lie opposite one another.
the two outer slats are extended at their rear ends by extensions 35d and 35e, in which a tension spring 36 is suspended to support the expansion effect.
the entire arrangement is mirror-symmetrical to an axis of symmetry S1-S1, which runs through the middle of the tweezers block and to which the direction of movement of the tweezers slide 28 runs parallel.
the number and dimensions of the slats 35 are not too critical: 10 to 60 slats with a thickness of 0.2 to 0.5 mm, a height of 3 to 6 mm and a length of 25 to 60 mm can preferably be used .
Spring steel can be used as the material, but preferably a highly elastic light metal alloy.
FIG. 7 shows a top view of a lamella 35 in the same viewing direction as in FIG. 6, but on a greatly enlarged scale.
a clamping head 35f At the free end 35a there is a clamping head 35f, which is delimited from the remaining part of the lamella 35 by two lateral recesses 35g and 35h. This makes it a very defined one Force can be exerted on the hair to be torn out, and hair that has already been torn out can escape into the two recesses without impairing a subsequent clamping process.
a bore 351 for receiving the swivel axis 31. Beyond the bore 351, the lamella 35 is tapered up to its end 35m, which facilitates spreading by means of the tension spring 36.
FIG. 8 first shows that there is no mechanically rigid positive control between the controls for the clamping jaws 23 and 24 and those for the tweezers slide 28.
the crank rod 20 is connected to the angle levers 21 and 22 without play, in this case, however, via a sliding block 37 which is mounted in a sliding block guide 38 with a dead gear "T". Details can be seen more clearly from FIG. 11, so that reference is first made to this figure.
crank rod 20 engages on the sliding block 37 via a pivot pin 39 which is mounted in the sliding block guide 38 with a dead gear "T".
the relative direction of displacement is indicated by the double arrow 40 and runs parallel to the axis of symmetry S1-S1 of the tweezer block (FIG. 6) or parallel to Parallel guide 27, of which only the guide pin 27a is shown in Figure 10.
the link guide 38 is rigidly connected to the tweezers slide 28 and engages around the link block 37 in the form of a "C", so that it is impossible to move the link block up or down.
the link guide 38 has two lateral slots 38a and 38b through which the free ends of the angle levers 21 and 22 are guided with a corresponding range of motion.
angle levers 21 and 22 can perform pivoting movements in the sense of the arcuate double arrows during an oscillating movement in the sense of the double arrow 40 - driven by the crank rod 20.
a relative movement with respect to the tweezers slide 28 or the tweezers frame 30 is also possible.
the tweezers slide 28 is under the action of two weakly curved leaf-shaped springs 41 which are firmly connected at one end to the tweezers slide 28 and engage at their opposite end in abutments 42 which are designed as cutting edge bearings.
Figure 9 shows the springs 41 and 41 ⁇ once in the unhooked state (solid lines) and once in the pretensioned state (dashed lines). As a result, the tweezers slide 28 is biased to the right in relation to FIGS. 8 and 9.
the clamping jaws 23 and 24 necessarily exert a corresponding clamping pressure on the tweezer block 32, because a stop prevents the axes 25 and 26 from evading to the left and thereby opening the clamping jaws 23 and 24.
the tweezers slide 28 has two stops to its stroke limit, of which the stop limiting the retraction movement lies in the area of the parallel guide 27 and is not visible here, while the stop 43 for limiting the forward movement has the shape of a bracket which interacts with an adjustable counter stop , which is not visible here because it lies under the crank rod 20.
the adjustability of the counter stop for the stop 43 is necessary because the maximum approach of the tweezers block to the support device 10 must be adjusted in order to avoid damage.
two leaf-shaped return springs 44 are provided, which are fastened at one end to the tweezer slide 28 (via the bow-shaped stop 43) and resiliently rest on the tweezer frame 30 with their other end, so that push it down.
a boom 46 is located on the chassis 12, the longitudinal axis of which extends parallel to the direction of movement of the tweezers slide 28.
This cantilever 46 carries a stop 47, which in the present case is formed by a lifting cam 48, which is pivotally mounted in the cantilever 46 about an axis 49.
the lifting cam 48 is held in the position shown in FIG. 9 by a return spring 50, which partly runs parallel to the arm 46, partly runs in an arc around its free end and engages in a groove of the lifting cam 48.
the lifting cam 48 is approximately V-shaped and is mounted on the axis 49 near its apex.
a projection 51 On the underside of the tweezers frame 30 there is a projection 51, which consists of two eyelets and a cylindrical pin extending between the eyelets. In Figures 9 and 10 only one of these eyelets and the end face of the cylinder pin is shown.
the relative position of the lifting cam 48 and the projection 51 is selected such that the projection 51 runs into the recess of the V-shaped lifting cam 48 during its forward movement and thereby pivots into the position as shown in FIG. 10.
the lifting cam 48 is pivoted into the position shown in FIG. 10 by tensioning the return spring 50, the projection 51 and thus the tweezer frame 30 being pivoted about the pivot axis 31, the free ends of the lamellae 35 being pivoted by several millimeters, for example by 4 up to 5 mm.
crank pin 17 lifts the front face 37c of the sliding block 37 from the stop 38c of the sliding block guide 38, so that the dead gear "T" is established again.
This process is not only due to the inertia of all the components connected to the tweezers slide 28, but also to the tension of the springs 41.
the angle levers 21 and 22 are accordingly torn about the axes 25 and 26 accordingly, so that a correspondingly high clamping pressure Jaws 23 and 24 is the result.
the tweezer block 32 with the clamped hair is now pulled back into the position shown in FIG. 8, the hair being torn out.
the sliding block 37 cannot be moved beyond the position shown in FIG. 8 from the open side of the sliding guide 38.
the tweezers block 32, the clamping jaws 23 and 24 and the angle levers 21 and 22 form a stop, at least effectively.
the tweezers slide 28 is inevitably taken along by the sliding block 37 because any further relative movement between the sliding block 37 and the sliding block guide 38 is prevented by the reaction forces of the tweezer block 32 acting on the angle levers 21 and 22.
an extraordinarily effective clamping of the lamellae is achieved with the tweezer block during the retraction movement of the tweezers slide.
FIG. 12 shows a side view of details of two variants of the support device 10. In both cases, this consists of a congruent arrangement of sheet metal strips which are bent essentially in a U-shape. In the following definition, reference is made to the direction of arrow 11, which indicates the direction of advance.
Each individual sheet metal strip consists of a rear leg 10a and a front leg 10b and a yoke 10c connecting these two legs.
the legs 10a and 10b are firmly connected to one another in order to maintain defined gaps for the insertion of the hair and are inserted in their entirety into the housing attachment 6 (FIG. 1).
the tweezer block 32 also executes its movements described above between the legs 10a and 10b.
the yoke 10c is extended in the feed direction beyond the straight extension (dash-dotted lines) of the front leg 10b to a reversal point 10d, from which the sheet metal strips are returned to the front leg 10b at an acute angle to the yoke.
a reversal point 10d from which the sheet metal strips are returned to the front leg 10b at an acute angle to the yoke.
the dash-dotted lines indicate the course of the leg 10b, as it is given in the embodiment of Figure 1.
the approximately triangular course of the projection in the area of the reversal point 10d can be made much more acute than this is shown in Figure 12.
FIG 13 shows, on an enlarged scale, further details of the tweezer frame 30: from a front frame part 30a, which encloses a cuboid cavity 30b, two parallel rockers 30c project inwards, which have bores 30d in their free ends, the axes of which are aligned with the axis A1-A1 coincide in Figure 6, ie
the tweezer frame 30 is mounted on the pivot axis 31 by means of the bores 30d and thus carries out the same pivoting movements as the tweezer block 32. This tweezer block protrudes forward from the frame part 30a, as is shown in part of the other figures.
tweezers slide 28 essential parts of the tweezers slide 28 are two parallel guide tubes 28a and 28b which can be moved on the guide pins 27a and 27b.
the guide tubes 28a and 28b are rigidly connected to one another by two cross members 28c and 28d. In which 8, the rear crossmember 28d is replaced by the bow-shaped stop 43.
the guide tubes 28a and 28b carry the two axes 25 and 26 with the angle levers 21 and 22 at their front ends.
a tweezer system P is shown, which is formed from only two clamping heads K1 and K2, of which the lower clamping head K1 in the drawing is firmly connected to a carriage S, while the upper clamping head K2 in the drawing by two pivot bearings 52 and 53 is pivotally attached to the carriage S.
the mutually facing inner surfaces of the clamping heads K1 and K2 are provided with a fine rib-shaped profile 54, which form the two boundary walls of a clamping gap KS. These walls form a narrow rectangle, the longest axis of which runs perpendicular to the direction of oscillation of the carriage S, which is indicated by the double arrow 55.
the chassis 12 is also provided here with two guide pins 27a and 27b which, together with guide sleeves of the carriage S, which are not described in more detail, form a parallel guide 27.
the tweezer system P can be withdrawn from this outer end position by means of a crank rod 57, the end of which is not shown and is connected to a crank mechanism. As a result, the crank rod 57 executes superimposed pivoting movements in the direction of the double arrow 58.
the crank rod 57 is connected via a joint 59 to a tension and compression member 60, which is connected via two brackets 61 to two levers 62, which are rigidly attached to the clamping head K2.
the tabs 61 can only perform a limited pivoting movement between the levers 62.
the lower pivot pin 63, on which the tension and compression member 60 engages, lies below a pivot axis defined by the swivel bearings 52 and 53, so that a pull on the tension and compression member 60 narrows or closes the clamping gap KS with firm clamping of hair.
This side guide can consist, for example, of a fork-shaped rocker which prevents transverse deflection of the tension and compression member 60.
the force with which the tweezer system P is closed depends on the preload of the leaf springs 41, but not least on the inertial forces which exert a reaction force on the tension and compression member 60. In any case, however, the clamping gap KS is closed first and then the carriage S with the clamping heads K1 and K2 and pinched hair moves to the right, the hair is reliably pulled out.
FIGS. 15 and 16 show a fourth exemplary embodiment of a tweezer system P, which in this case, however, has a plurality of clamping gaps lying next to one another, and this is also the case with the subject of FIG. 6.
the tweezers system P has a row arrangement R of alternately arranged lamella pairs L1 / L2.
Each pair of lamellae is pivotally supported between its ends on a respective hinge pin G, which is mounted in a carriage S, which can be moved in a controlled manner in the direction of the feed opening (not shown here), of which only a frame part is shown here.
the on the The ends of the lamellae aligned with the feed opening are designed as clamping heads K1 and K2, while the opposite ends of the lamellae have control surfaces F1 and F2 which are arranged in pairs and can be expanded by a control body C.
the control bodies C are also provided in a row arrangement and fastened to a cross strut 64, which in turn is connected via a tension and compression member 65 to a drive device, not shown.
the lamella pairs L1 / L2 are supported by a pressure roller 66 on the respectively adjacent lamella pair. While the hinge pins G are firmly connected to the slide S, the pressure rollers 66 can carry out a small relative movement, predetermined by the lever ratios, transversely to a plane through the axes of all the hinge pins G. It is of course also possible to firmly connect the pressure rollers 66 to the carriage S, but then the hinge pins G must be able to perform the required relative movement.
clamping heads K1 and K2 are first brought up to the surface of the skin to take up the hair in a spread state.
the clamping heads near the surface of the skin are then moved into the clamping position by pinching the hair.
This end position is shown in Figure 15.
the clamping heads are pulled away from the skin surface into a retracted position, pulling the hair out, and finally the clamping heads in the area of the retracted position, with the hair being ejected, are returned to the spread position emotional.
This movement mechanism takes place through targeted relative movements of the carriage S on the one hand and the tension and compression members 60 and 65 on the other hand.
FIG 16 finally shows a single lamella L2.
the clamping head K2 has a bevel 67 at its front end (based on the movement of the dehairing device in operation) which explains the insertion of the hair to be torn out.
the clamping head K2 is also provided with a profile 54, and above this profile there is a recess 68 which facilitates the ejection of the hair and ensures that the closing movement of the clamping gap KS is not hindered by hair accumulation.
a semi-cylindrical groove 69 Between the two ends of the lamella L2 there is - in closer proximity to the clamping head K2 - a semi-cylindrical groove 69, into which the hinge pin G comes to rest when all the lamellas are assembled. There is a distance between the groove 69 and the control surface F2, which is determined by the predetermined lever ratios.
