Definitions

  • the invention relates to an epilation device for removing hair from the human body, with a housing which is durable in the hand of the user, with a clamping element having a motor-driven rotary cylinder and with at least one actuating element which passes through the rotary cylinder and for actuating the latter Coupled clamping elements is used, 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 which is fixedly arranged 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 rotatably attached to the epilation head at a predetermined distance from one another by means of a rod in each case. They act briefly on the actuating rods in order to achieve a rapid swiveling and closing movement of the clamping lamellae, which is a safe one Pinching and plucking the hair ensures. Due to this brief, sudden exposure to noise, which leads to a relatively high noise level due to the high speed of the rotating cylinder and the double clamping movement per cylinder revolution, which is perceived by the user as annoying. In addition, there is the wear both on the rollers and on the actuating rods, for example as a result of the sudden action of the pressure elements on the actuating elements and as a result of material fatigue.
  • the object of the invention is to design an epilation device of the type mentioned in such a way that it has a significantly lower noise level in operation without impairing the plucking performance.
  • At least one ramp leading to the actuating element is advantageously provided between the rotary cylinder and the pressure element.
  • the ramp is guided past the pressure element, the significant difference in height between the rotary cylinder and the actuating element being reduced, and thus avoiding the actuating element striking the pressure element.
  • the pressure elements are run over by the ramps, which first rise gradually in the direction of the actuating elements and gradually run out after the actuating elements, thereby achieving a more uniform movement and thus a reduction in noise.
  • the ramps are formed on the end faces of the rotary cylinder. This one-piece design of end faces and ramps is particularly inexpensive and easy to assemble.
  • a disk is arranged between the pressure element and the ramps. This disc bridges the existing difference in height between ramps and actuators, so that the transition to the clamping position takes place without a step. As a result, there is a further equalization of the movement sequences, which leads to an additional reduction in noise. Due to the constant installation of the components mentioned, the wear on the pressure elements and actuating elements is reduced.
  • ramps are designed as separate parts, different materials can be used for end faces and ramps, depending on the respective requirements for strength.
  • the ramps can advantageously be attached to the end faces, in particular plugged on, so that there is the possibility of replacing the ramps if necessary and thereby restoring the noise-reduced functioning of the epilation device.
  • the ramps are integrally formed on the actuating elements, which gives the advantage of integrally forming ramps and actuating elements.
  • the ramps can be plugged onto the actuating elements. This ensures interchangeability of the ramps with minimal effort.
  • the actuating elements have end pieces which have an approximately trapezoidal cross section.
  • the lateral bevels of the end pieces are approximated to the bevels of the ramps, so that this comparatively paragraph-free curve control means that the pressure element can pass to the actuating element when the rotary cylinder rotates in continuation of the ramps without striking the actuating element.
  • two actuating elements interacting in pairs are preferably arranged diametrically to one another in the epilation device and ramps are provided on both sides of the actuating elements protruding from the end faces of the rotary cylinder in the direction of the actuating elements.
  • This arrangement allows on the one hand a double clamping and plucking movement per revolution of the rotary cylinder, so that the epilation device works effectively, on the other hand by the existing ramps on both sides of the actuating elements that the operating noise of the device is kept low.
  • two ramps are integrally connected to one another and form approximately a semicircular segment of variable thickness, with diametrically opposite edge regions having a maximum thickness.
  • a discharge ramp and a run-up ramp for the pressure element are advantageously connected to one another in part, which can be used on both sides of the actuating elements. The solution according to the invention can thus be carried out with minimal effort.
  • the semicircular segments have U-shaped recesses in the center, in which the lugs serving for lateral mounting of the threading elements are received during assembly. This ensures that the segments are secured in their position at the same time.
  • the ramps advantageously consist of an elastic material, preferably elastomer. If the metallic disks are pushed against the ramps by the pressure elements, the elastic material of the ramps dampens the noises that occur and the movements are smoothed out. Since the disks are constantly in contact with the ramps in an area of their surface, this noise damping has an advantageous effect on the overall operating noise of the device.
  • 1 shows a device for removing human body hair or an epilation device, partially in section, which consists of a housing 2 and a removable epilation head 3 for receiving a drivably mounted rotary cylinder 4.
  • the rotary cylinder 4 is driven by an electric drive motor 10 which can be connected to a power supply or to a rechargeable battery 5 or replaceable batteries.
  • the drive motor 10 is in drive connection with a drive wheel 8 of the rotary cylinder 4 via a gear 7 having numerous gears 9.
  • the epilation head 3 which can be plugged onto the housing 2, has a left bearing shell 11 which is fixedly or integrally connected to a horizontally running support part 13.

  • the threading elements 49, 50 have projections 53 and 56 on the right and left sides, each with a groove 54 and 57.
  • the gear wheel 8 is inserted into the groove 54 and an end plate 55 into the groove 57 of the diametrically opposite lugs 53 and 56 of the threading elements 49, 50.
  • the two lugs 53 and 56 are deformed to such an extent that the gear 8 and the end plate 55 easily fit into the corresponding groove 54, 57 can be inserted. In this way, a clamping connection between the bearing part 24 of the axis 19 and the threading elements 49, 50 is created on both sides of the threading elements 49, 50.
  • the gear 8, the end plate 55 and the numerous clamping elements 42, 43 each have a rectangular opening 59, 44, 61, so that the clamping elements 42, 43, the gear 8 and the end plate 55 can be pushed onto the bearing part 24.
  • These parts are, among other things, part of a rotating cylinder 4, which is rotatably supported on the bearing part 24 on the axis 19 of the rotating cylinder 4 and is driven by the gear 8.
  • bracket 22 is received in the epilation head 3 in a groove 23 which is only partially indicated in the drawing.
  • the axis 19 of the rotary cylinder 4 of the epilation head 3 according to FIG. 3 serves to rotatably accommodate the central, rectangular, elongated bearing part 24.
  • the axis 19 protruding on both sides of the bearing part 24 has a bearing journal 25 at the end, each with a slot opening 20.
  • clamping elements 42 and 43 are arranged on the actuating elements 26 to 29 or are connected to them in terms of drive. Numerous clamping elements 42, 43 interact and each form a clamping device for removing body hair from humans.

  • the movement sequences can be made more uniform compared to the conventional design of the gear wheel 8 or End plate 55 without ramps 66, 67, 68 and 69 a significant reduction in the noise level when using the epilation device 1 can be achieved.
  • the ramps 67, 68 and 69, 66 formed as separate parts each form approximately a semicircular segment of variable thickness 70, which has diametrically opposite edge regions 71, 72 of maximum thickness and uses actuating elements 26, 28 and 27, 29 on both sides can be.
  • the U-shaped recess 73 is provided, which is arranged centrally in the semicircular segment 70 and at the same time serves to secure the segment 70.
  • the disc 63 even without ramps 66, 67, 68 and 69, brings about a reduction in the noise level due to its arrangement between the pressure elements 38 and the actuating elements 26, 28 and 27, 29, since sudden impacts caused by the collision of actuating elements 26, 28 or 27, 29, which are driven by the rotary cylinder 4, and the pressure elements 38 are avoided by them.
  • the situation is similar if the actuating elements 26, 28 or 27, 29 lose contact with the pressure elements 38 and the actuating elements 26, 28 or 27, 29 suddenly relax.
  • the disc 63 avoids these sudden movements by bridging the height differences between the actuating elements 26, 28 or 27, 29 and the end faces 65 and lowers the operating noise of the epilation device 1 by equalizing the movement sequences.
  • ramps 66, 67, 68 and 69 are formed or attached to the end faces 65, ie gear wheel 8 or end plate 55, the disks 63 are constantly in contact with the ramps 66, 67, 68, 69 with an area of their surface and accordingly become essential less deformed.

  • the existing height difference between the maximum ramp height and the actuating element 28 is thereby easily overcome by the cylindrical shape of the pressure element 38 and the trapezoidal end piece 64 of the actuating element 28.
  • the clamping elements 42, 43 are opened by the sudden release of the actuating means and the transition of the pressure element to the descending ramp 67.
  • the existing ramps 66, 67, 68 and 69 there is already a significant reduction in the operating noise of the epilation device.
  • the pressure element 38 is in an intermediate position between the actuating elements 26 and 28, on the center of the ramps 66 and 69, in the open position of the clamping elements 42, 43. Between the ramps 66, 69 and the pressure element 38 the disc 63 is clamped so that it cannot move between the end disc 55 and the pressure element 38 and can thus vibrate if necessary. In addition, it comes to rest on the trapezoidal end pieces 64 of the actuating elements 26 and 28.
  • the bracket leg 21, on which the pressure element 38 is arranged, is received through the slot 20 of the bearing pin 25 and thereby guided in the axial direction.

  • the clamping elements 42, 43 are opened again.
  • FIGS. 16 and 17 each show an embodiment variant in which the ramps 66, 67 are molded or attached to the actuating element 28. Between the rear of the ramps 66, 67 and the rotary cylinder 4 (end face 65) there remains a gap 75 which ensures the movement of the actuating element 28 with the ramps 66 and 67 when acted on by the pressure element 38, which already starts when the pressure element 38 is above the disc 63 comes into contact with the ramp 66.
  • the closing or clamping movement for the clamping elements 42, 43 is triggered when the pressure element 38 has reached the upper region of the ramp 66, overcomes the height difference to the actuating element 28 via the trapezoidal end piece 64 and thus acts on the flat surface of the actuating element 28, by tilting with the disk 63 and coming to rest on the flat surface of the actuating element 28.
  • This phase of the movement corresponds to the clamping phase.
  • the disc 63 tilts due to the further movement of the rotary cylinder 4 via the trapezoidal end piece 64 of the actuating element 28 and comes to rest on the ramp 67.
  • This process is repeated again during one revolution of the rotary cylinder and proceeds analogously for all actuating elements 26, 27, 28, 29.
