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 rotating cylinder having motor-driven clamping elements and with at least one actuating element passing through the rotating cylinder for actuating the latter coupled clamping elements, wherein the actuating element can be actuated by a pressure element assigned to it and displaceable against the pressure of a spring.
  • An epilation device of the type mentioned at the outset is known from EP 0 328 426 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 passing 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.
  • Each of the actuating rod units consists of two mutually associated actuating rods, each of which is acted upon at the end by a roller rotatably mounted on a rod arranged in a fixed manner in the epilation head, and is 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.
  • the two rollers acting on the actuating rods are attached to the epilation head at a predetermined distance from one another by means of a rod in each case. 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 is pinched off and if the clamping force is too weak, it is not clamped sufficiently and therefore not pulled out of the skin. Added to this is the wear that occurs on both the rollers and the actuating rods when using the epilation device, 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 a fixed manner in the epilation head acts on each of the actuating rods directly or indirectly with the interposition of a specially designed pivot bearing once per revolution of the rotary cylinder, the return of the respective actuating rod being accomplished by means of a spring acting on the end facing away from the roller.
  • a poultry plucking machine is known from FR 1.032.138, which essentially consists of an engine and a plucking block.
  • the motor and the plucking block are assembled as separate assemblies on one gesture and connected to each other by a drive belt.
  • Clamping disks are arranged in the plucking block, with a conical roller acting on the outer clamping disk.
  • the roller itself is rotatably mounted in the plucking block and is adjustable with a wing nut using a clamping screw.
  • 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 the clamping force of interacting clamping elements can be changed by means of an adjusting device.
  • the solution according to the invention can be used in a large number of differently designed rotary cylinders of epilation devices.
  • the clamping elements of the rotary cylinder are coupled to two actuating elements which can be moved relative to one another and that the distance between the clamping elements of the first actuating element and the clamping elements of the second actuating element can be changed by means of an adjusting device which acts directly or indirectly on at least one of the actuating elements is.
  • the change in the spacing of interacting clamping elements via the actuating elements which can be moved relative to one another by means of an adjusting device brings about an increase in the clamping force when the distance is reduced and a reduction in the clamping force of the mutually associated clamping elements when the distance is increased.
  • An adjusting device acting indirectly or indirectly on the actuating elements of clamping elements thus ensures 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 manufacturing tolerances, on the other hand, and on the other hand by the user, who individually adjusts the clamping force to the existing hair thickness carry out and can also correct a decrease in the clamping force due to wear by means of readjustment.
  • the adjusting device consists of at least one spring determining the clamping force and at least one tensioning element acting on the spring.
  • a preferred embodiment of the invention is characterized in that a first of the actuating elements movable relative to one another is fixedly connected to a drive shaft passing through the rotary cylinder, that the drive shaft is rotatably mounted in the housing, and that a second actuating element is guided through the clamping elements of the first actuating element and is displaceably mounted on the first actuating element against the pressure of a spring acting on both actuating elements and that the position of the second actuating element can be changed via a control element and a displaceably mounted pressure element by a spring resting on the pressure element and at least one tensioning element acting on the spring.
  • the spring which determines the clamping force on the clamping elements, is preferably designed as a bow spring.
  • An optimal setting of the clamping force of the clamping lamellae via the actuating elements which can be moved relative to one another is achieved by the interaction of the spring of the adjusting device with two clamping elements acting on it, one of the clamping elements being an eccentric or polygonal rod which is adjustably mounted in the housing with different distances between its lateral surface (s) Axis of rotation is formed and the other clamping element is arranged as a fixed stop for the spring in the housing in the area between the pressure element and the clamping element.
  • the second clamping element arranged in the area between the one clamping element and the pressure element is arranged in the housing as an adjustable stop for the spring with different distances between its lateral surface and its axis of rotation.
  • the particular advantage of this measure is that after assembly of the epilation device, all manufacturing tolerances can be compensated for by means of such an adjustable stop, as a result of which the adjusting device is given a defined basic setting, which subsequently provides optimal fine adjustment by the user by means of the further action on the spring.
  • one side of the bow spring rests on the pressure element and the tensioning element and the opposite side of the bow spring rests on the tensioning element.
  • an adjusting lever is provided on the clamping element.
  • the control element is preferably provided with a control curve having an elevation and a depression.
  • a ball is mounted in a rolling manner in the pressure element.
  • two stops for the bow spring are provided on the wall of the bearing point.
  • one side of the bow spring rests on the pressure element and on the two stops as well as on the tensioning element and the opposite side of the bow spring rests on the stop.
  • a major advantage of such a configuration of the adjusting device is that the bow spring resting on the two stops and on the tensioning elements can be pretensioned by turning the stop provided on the opposite side of the bow spring.
  • a softer bow spring instead of a hard bow spring, a softer bow spring, that is to say a bow spring with a flat spring characteristic, can be used.
  • the use of a soft bow spring with a flat spring curve results in less fluctuation in the clamping forces occurring in the vicinity of the specified nominal clamping force point with the same manufacturing tolerance range.
  • Another embodiment of the invention is characterized in that in the open state of the clamping elements there is a distance between the ball and the recess of the control cam. Because of this distance, the pressure element equipped with a ball is not in constant contact with the control curve of the control element during the course of one revolution of the rotary cylinder. On the one hand, this favors the setting of a pretension of the bow spring after assembly and, on the other hand, serves to save drive energy.
  • one of the actuating elements which can be moved relative to one another is fixedly connected to a drive shaft passing through the rotary cylinder and the drive shaft is displaceably mounted in the housing against the pressure of a spring which bears against the tensioning element and acts on the drive shaft.
  • the second actuating element which is assigned to the first actuating element fixedly connected to the drive shaft, is displaceably mounted against the pressure of a spring acting on both actuating elements and the displaceably mounted actuating element can be acted upon indirectly or directly by a pressure element arranged in a stationary manner in the housing.

  • the drive shaft is guided through the clamping element and is rotatably and displaceably mounted therein, and that the opposite end of the drive shaft protruding from the rotary cylinder is accommodated in a second bearing point provided in the housing.
  • the particular advantage of this embodiment consists in the use of already existing components of the epilation device for the integration and control of the components of the adjustment device, such as the use of one of the bearings of the drive shaft as a tensioning element, the support of the spring on this bearing and a counter bearing formed on the drive shaft, the displacement of the drive shaft within the two bearing points and the use of the pressure element arranged in a stationary manner in the housing for the actuating stroke of the displaceably mounted actuating element which can be displaced by means of the adjusting device.
  • all that is required to adjust the clamping force of interacting clamping elements is an additional component in the form of a spring that bears against the tensioning element and acts on the drive shaft.

Based on the setting shown in FIG. 7, the spring force of the bow spring 49 can be twisted by the tensioning element 50 and the resulting contact of another surface of the polygonal bar on the bow spring 49, the bow spring 49 in the direction of arrow F 2 by the adjustment path b '- see Fig. 9 - be increased.
  • the clamping effect of cooperating clamping elements 5 and 6 can be improved in connection with the change in the clamping force in that at least one of the paired clamping elements 5 or 6 is made elastic. This measure increases the size of the interacting clamping surfaces of a pair of clamping elements and thus prevents pinching of pinched hair.
