Definitions
- the invention relates to an epilation device for removing hair from the human body with a housing that can be held in the hand of the user, with a rotary cylinder having clamping elements driven by a motor, and with at least one actuating element passing through the rotary cylinder ment for actuating the clamping elements coupled thereto, the actuating element being operable by a pressure element associated therewith and being displaceable against the pressure of a spring.
- An epilation device of the type mentioned is known from EP 0328426 A2.
- the rotating cylinder which can be set in rotation by a rotatingly driven shaft, consists of pivotably mounted clamping lamellae which are caused to pivot by the actuating rods which pass through the rotating cylinder.
- Two actuating rod units are arranged diametrically opposite one another on the shaft, as a result of which clamping operations are achieved with every half revolution of the rotary cylinder, and each actuating rod unit consists of two mutually assigned actuating rods, each of which is arranged at the end of one on one in the epilation head in a stationary manner
- Rod rotatably mounted roller is applied once per revolution and moved back and forth in opposite directions against the pressure of a common spring.
- the actuating rods assigned to one another transmit this movement to the clamping lamellae, which pivot in pairs towards one another and are finally pressed against one another in the region of their outer edge.
- Each of the two rollers acting on the actuating rods is rotatably attached to the epilation head by a rod at a predetermined distance from one another. Due to the manufacturing process, this distance cannot be exactly maintained, as a result of which the clamping force of the clamping lamellae in the clamping area is subject to considerable fluctuations. If the clamping force is too strong, the relatively thin hair becomes pinched off and insufficiently clamped when the clamping force is too weak and therefore not pulled out of the skin. In addition, there is the wear that occurs both on the rollers and on the actuating rods when the epilation device is used, for example due to friction and material fatigue.
- the rotary cylinder of this epilation device consists of immovable clamping elements and associated pivoting clamping elements.
- the non-movable clamping elements are part of a rotatingly driven shaft.
- Two diametrically opposed actuating rods penetrate the rotary cylinder for the purpose of actuating the respective row of clamping elements.
- a roller rotatably mounted on a rod arranged in the epilation head acts directly or indirectly on each of the actuating rods once per revolution of the rotary cylinder with the interposition of a specially designed pivot bearing, the return of the respective actuating rod by means of an end facing away from the roller acting spring is accomplished.
- the object of the invention is to improve the plucking of hair with an epilation device of the type mentioned.
- this object is achieved in an epilation device of the type mentioned at the outset in that means are provided for adjusting the clamping force of the clamping elements.
- the position of the actuating element can be changed by means of an adjusting device.
- the position of actuating elements interacting in pairs with respect to one another can be changed by means of an adjusting device.
- the change in the position of an actuating element provided with clamping elements to a pressure element assigned to the actuating element by means of an adjusting device causes an increase in the clamping force when the distance is reduced and a decrease in the clamping force of the clamping elements assigned to one another when the distance is increased.
- An adjusting device acting indirectly or indirectly on the actuating elements of clamping elements thus guarantees an optimal setting of the clamping force of interacting clamping elements of an epilation device, on the one hand by the manufacturer, who can compensate, for example, manufacturing tolerances, and on the other hand by the user, who individually adjusts the clamping force perform on the existing hair thickness and can also correct a decrease in the clamping force due to wear by means of readjustment.
- the pressure element acting on the actuating element is designed as an adjustable eccentric.
- the pressure element acting on the actuating element is designed as a roller and rotatably mounted on an adjustable eccentric.
- the contact surfaces of the pressure element and of the actuating element which act directly or indirectly on one another are designed to run at right angles and / or wedge-shaped to one another.
- a guide disc is provided between the pressure element and the actuating element.
- the position of the pressure element is adjustable by means of an adjusting nut acting on the pressure element.
- the eccentric and / or the roller are arranged on a rod which is fixedly arranged in the epilation head.
- the eccentric and / or the roller are arranged on a rod which is adjustably arranged in the epilation head.
- the rod is formed from a straight pin.
- the rod is preferably designed as a U-shaped bracket.
- abutments are assigned to the side legs of the bracket, the position of the side legs relative to the abutments being variable by means of a further adjusting device.
- the distance between the pressure elements and the length of the path under the action of clamping force, ie the path that the actuating elements and the pressure elements cover in contact with one another is changed via the pretensioning of the bracket. If this path is lengthened, the power required to operate the epilation device increases. Shortening the path reduces the power required.
- the adjustment device is advantageously designed as an adjustable eccentric, whereby a continuous change in the position of the side legs is possible.
- the eccentric is coupled to the eccentric, which changes the distance between the pressure elements which act on the actuating elements.
- the eccentrics are made in one piece, i.e. are provided on a component
- the change in distance of the pressure elements to each other by means of adjustment of the first eccentric causes a simultaneous change in position of the side legs to the abutments via the second eccentric.
- the bracket If the maximum possible adjustment stroke of the eccentric, i.e. the maximum clamping force is set, the bracket also reaches a maximum pre-tension. As a result of this increased pretension, the distance to be covered by the actuating elements in contact with the pressure elements and thus under the action of clamping force is shortened, as a result of which the required power of the epilation device is reduced.

- a disk 63 is provided between the rollers 512, 513 and the stops 500, .501 adjacent to these.
- a cam 514 designed as a double eccentric is rotatably mounted - see view from above according to FIG. 11a.
- the cam is adjustable by means of an adjusting screw which is passed through the epilation head - not shown.
- the bracket arms 508 and 509 of the first bracket arm pair perform an analog spreading movement and transmit this via the rollers 512 and 513 to the stops 500 and 501 of the actuating elements 26, 27.
- the curve shape provided in FIG The distance between the actuating elements 26, 27 via their stops 500, 501 can be changed by cam 514, and consequently the spacing of the clamping elements 42, 43 arranged on the actuating elements 26, 27.
- the clamping force of the clamping elements 42 , 43 can accordingly be changed accordingly via the change in distance emanating from the cam 514, ie adjustable.
- FIG. 12 shows the epilation head 3 of an epilation device 1, the rotary cylinder 4 of which consists of a component 261 mounted rotatably in the epilation head 3 with clamping elements 42 fixedly arranged thereon and movable clamping elements 43 assigned to them.
- the movable clamping elements 43 are coupled to an actuating element 27 passing through the clamping elements 42 of the component 261 and are pivotably mounted in bearing points provided on the component 261. To hold and guide the actuating element within the rotary cylinder 4, this is assigned a rod 601 passing through the clamping elements 42 and 43.
- the actuating element 27 and the rod 601 are mounted within an opening of a guide element 602 and by means of a pin 603 penetrating the actuating element 27, the rod 601 and the guide element 602 to form a unit connected.
- the end face 604 of the guide element 602 bearing against the pressure element 39 is mounted in the end plate 605 of the rotatably mounted component 261 so as to be horizontally movable.
- the end of the actuating element 27 facing away from the pressure element 39 is in the end disk 606 of the component 261 provided opening 607 horizontally displaceable against the pressure of a spring.
- a second actuating element 28 is arranged and formed accordingly in the component 261 by 180 ° to the previously described actuating element 27. Since this second actuating element 28 is not in contact with the pressure element 39, the spring is in the relaxed state. As a result, the movable clamping elements 43 assume a predetermined distance from the clamping elements 42, which is necessary for grasping the hair to be pulled out.
- the component 261 of the rotary cylinder 4 is arranged in the epilation head 3 between two bearing blocks 608, 609 - of which only the bearing block 609 is shown in full for reasons of better illustration - and is rotatably mounted therein.
- the component 261 is driven in rotation by the drive wheel 8 and a drive device located in the housing.
- the pressure element 39 is rotatably mounted on an eccentric 10 designed according to FIG.
- the eccentric 10 provided with an adjusting lever 100 is rotatably mounted on a rod 222 fixedly arranged in the epilation head.
- the eccentric 10 transmits its eccentricity via the pressure element 39 to the actuating element 27 or 28 and causes a corresponding change in distance between the pressure element 39 and the counterbearing of the actuating element 27 or 28 in the end plate 606 of the component 261. This change in distance causes a change in the clamping force between the clamping elements 42 and 43.
- the actuating element designated B stands for the actuating elements 26, 27 and 28, 29, which can be displaced in pairs relative to one another.
- FIGS. 13 and 14 each show the position in which the clamping elements 42, 43 (FIG. 1), which are not shown in these schematic representations, are in the open position. lung.
- the side legs 13, 21 of the bracket 22 rest in the slots 20 of the axis 19 and press against the axle ends, which form the abutments 80, 81 for the side legs 13, 21.
- the distance between the side legs 13, 21 corresponds to the length of the axis 19.
- the eccentric 10 with its small radius r is on the side of the abutment 80, in FIG. 14 with its large radius R.
- These positions show the minimal or The maximum possible adjustment stroke of the eccentric corresponds to the minimum and the maximum clamping force setting. Due to the fact that the eccentric 10 does not act on the axis 19, the pretension of the bracket 22 remains unchanged.
- FIGS. 13a and 14a correspond to the closed position of the clamping elements 42, 43.
- the actuating element B is in contact with the pressure elements 38, 39, the bracket 22 being only slightly spread by the small adjustment stroke of the eccentric 10.
- the resulting distances G and G 'between the side legs 13, 21 and the abutments 80, 81 are the same as a result of an automatic centering during operation of the device.
- the distance between the side legs 13, 21 at the level of the abutments 80, 81 takes on the value L1.
- the eccentric disc 10 acts in the clamping position at maximum clamping force with its large radius R via the pressure element 39 on the actuating element B, FIG. 14a.
- the bracket 22 is spread by the maximum adjustment stroke of the eccentric 10 so that it forms almost right angles with its side legs 13, 21.
- the resulting distance G, G 'between the abutments 80, 81 and the side legs 13, 21 is considerably greater than with a minimal clamping force setting.
- the distance between the side legs 13, 21 at the level of the abutments 80, 81 is increased to L2.
- 13 b shows an enlarged top view of the pressure element 39 with the eccentric 10 and the adjusting lever 100 and the actuating element B.
- the side leg 21 lies against the axis 19.
- the section between the position X in which the actuating element B comes into contact with the pressure element 39 and position Y in which the contact ends corresponds to the path under the action of clamping force. This path is short with a minimal clamping force setting, ie a minimal adjustment stroke of the eccentric.
- the maximum possible adjustment stroke which corresponds to the maximum clamping force setting, is achieved by rotating the eccentric 10 by means of the adjusting lever 100 by 180 °. With its large radius R, the eccentric 10 is located on the side of the actuating element B. As a result, the actuating element B comes into contact with the pressure element 39 earlier, which also ends later. The resulting path for the actuating element B under maximum force is correspondingly larger, as a result of which the device requires a higher power.
- This differentiated power requirement for the device with a minimal or maximum clamping force setting is disadvantageous, in particular for battery-operated devices. A reduction in the required power with maximum clamping force setting could accordingly be achieved by shortening the distance that actuating element B and pressure element 39 travel in contact with one another.
- the previous arrangement is changed by adding an eccentric 210.
- This eccentric 210 is arranged with respect to its eccentricity analogously to the eccentric 10 on the side leg 21 of the bracket and forms an extension of the eccentric 10.
- this eccentric 210 acts with its narrow side s directly on the abutment 80 via the side leg 21 of the bracket 22.
- the axis 219 is shorter by the amount s than the axis 19, as a result of which the pretensioning of the bracket 22 remains unchanged remains.
- the bracket 22 is spread analogously to the arrangement according to FIG. 13a. With a minimal clamping force, the resulting distance L1 between the side legs 13, 21 and the abutments 80, 81 corresponds to the distance L1 in FIG. 13a, since only the eccentric 10 acts over its small radius r.
- Figure 16 shows an arrangement with the maximum possible adjustment stroke, i.e. in which the eccentric 210 is arranged with its broad side S to the abutment 80.
- the eccentric 210 causes the bracket 22 to expand by the amount S.
- the pretensioning of the bracket 22 is thus significantly increased compared to the arrangement with only one eccentric 10 (FIG. 14).
- actuator B is in contact with pressure members 38, 39, i.e. the clamping elements 42, 43 in the clamping position.
- the eccentric 10 acts over its large radius R, whereby the clamping force is at a maximum.
- the distance L2 between the side legs 13, 21 corresponds to the distance L2 according to FIG. 14a. Because the eccentric 210 already acts on the axle end via its part S in the open position and the bracket 22 is expanded, the required expansion of the bracket 22 in the clamped position is considerably less than the arrangement in FIG. 14a. Accordingly, the path to be covered by the actuating element in contact with the pressure element becomes shorter and roughly corresponds to the path with a minimal clamping force setting.
- eccentric 210 With a minimal clamping force setting, the eccentric 210 with its narrow part s is located between the side leg 21 and the axis 219. The distance to be covered between the positions X and Y is due to the small difference. reference between the pretension of the bracket 22 and the clamping position.
- the distance to be covered by the actuating element B and the pressure element 39 during the clamping phase is approximately the same as the distance with a minimal clamping force setting. This means that the higher power required when operating the device with maximum clamping force setting can be significantly reduced by arranging a second eccentric.
