Definitions

  • the present invention relates to a hair cutting device that can be used as a shaver or a hair trimmer.
  • Rotary electric shavers commonly use coupling spindles for transferring the rotary power from the drive to the cutting system. Apart from that there are several secondary functions, one of which is exercising axial force onto the cutting elements. This is the closing force, by which the cutting elements are held to the shaving caps. Too little closing force allows a cutting gap to occur between the cutting elements and the shaving cap, with faulty cutting and hair pulling as a result. On the other hand, increasing the closing force also increases friction, whereby noise, wear, energy loss, and as a consequence of this, shortened battery life result.
  • Coupling spindles are commonly designed to exercise an approximately constant axial force (cutting pre-tension) that remains within a functionally acceptable window of operation.
  • a rotary drive shaver including an outer shearing foil supported on a head frame and an inner cutting unit holder having a center axis and carrying a plurality of inner blades in hair shearing engagement with the outer shearing foil.
  • the inner cutting unit holder is operatively connected to a rotary drive shaft of an electric motor so as to be driven thereby to rotate about the center axis.
  • the outer shearing foil is held movable in the direction of the center axis relative to the head frame, while the inner cutting unit holder is movable along the center axis relative to the rotary drive shaft so as to be floatingly supported thereby.
  • the outer shearing foil is connected to the inner cutting unit holder by means of a pin extending along the center axis such that the outer shearing foil and the inner cutting unit holder are movable together along the center axis relative to the head frame as well as the rotary drive shaft. Accordingly the contact pressure and thus the closing force between the inner blades and the outer shearing foil can be kept substantially at a constant level irrespective of the relative movement of the outer shearing foil to the head frame.
  • a rotary shaving apparatus wherein in the cutting unit there is integrated a mechanism for adapting the closing force depending on the torque transmitted from the cutting unit during the cutting operation.
  • a cam cooperating with a ramp surface on a carrier that is directed obliquely towards the coupling member viewed in a direction opposed to the drive direction, such that the cam is guided along the sloping ramp surface.
  • the driving surface and the driven surface cooperating therewith have mutually corresponding helical shapes.
  • the self-adaptive mechanism with the cooperating helical surfaces is contained within the cutting unit, it is unavoidably exposed to pollution from hair particles, skin flakes, and skin grease. Also it is confined to a very small space.
  • the pollution can build up, and can obstruct the movement of the segments, may cause mechanical contact and transmission of forces in places or directions that were not intended in the design. Due to this, the mechanism can get stuck, or work not as intended.
  • friction may build up and may impair the self-adaptive characteristic. In order to work, self-locking due to friction should be avoided, which, however, is not always ensured.
  • the cutting unit blades are rigidly attached to the self-adaptive mechanism. This makes the angle of the contact force on the helical ramps dependent on the angle of the cutting force, which is in reality highly variable. As a result of the varying contact force, the friction forces vary. Excessive cutting forces can contribute to uncontrolled self-locking.
  • the axial forces that are exercised by the cutting unit onto the cap are transferred directly from the helical ramp surfaces which are at some distance from the central axis.
  • the contact forces should be distributed equally among the three ramp surfaces, and the resulting force should be in the center.
  • the location of the resulting axial force will be eccentric and variable. This can negatively affect control over the mechanical working of the cutting unit in the beard cutting process, and the life of the cutting system.
  • the contact forces on individual ramp surfaces vary, and by this the magnitude of the friction forces, contributing to potential self-locking.
  • an object of the present invention to provide an improved hair cutting appliance that may be configured as a shaver or as a trimmer that delivers a variable axial force in response to the torque that is exercised on the cutting unit. It shall at least overcome some of the drawbacks mentioned above.
  • a hair cutting appliance comprising:
  • the drive spindle (corresponding to the coupling spindle mentioned above) comprises a mechanism that delivers a variable axial force in response to the torque that is exercised on the drive spindle.
  • the closing force is automatically and instantaneously adapted to optimize for cutting performance or wear and energy loss, as the user's situation of the moment requires.
  • the mechanism can be realized by a simple modification in geometry of existing drive spindles, without the addition of parts.
  • the self-adaptive mechanism Since the self-adaptive mechanism is accommodated in an area that is separated from the hair chamber in which the beard's hairs are cut and collected, there is no problem with respect to pollution from hair particles, skin flakes, skin grease etc.
  • the self-adaptive mechanism can be arranged, for example, in a separate compartment, or outside of the cutting unit. Thereby the mechanism remains unaffected by pollution.
  • the cutting unit typically consists of a metal part, with a plastic molded insert.
  • the metal blades of the cutting unit are sharpened, and grinding particles are released. These particles stick onto the cutting units plastic insert, and may affect the friction properties in the prior art mechanism that is located within the cutting unit. According to the invention the mechanism will not be affected by the sharpening process, as the spindle parts are manufactured separately.
  • the cutting unit and the self-adaptive mechanism are mechanically separated, whereby it is avoided, that varying contact forces between the cutting unit blade and the user's face lead to a variation of friction forces and that excessive cutting forces can lead to uncontrolled self-locking.
  • the axial force from the self-adaptive mechanism is always exercised to the approximate center of the cutting unit. Irregular contact between the abutment element and the corresponding slanted abutment surface will not affect the location of the axial force onto the cutting unit.
  • the axes of the segments are not rigidly aligned, but move about in a continuous motion while they are rotating.
  • a continuous complex motion between the abutment element and the associated abutment surface will occur, and the contact angles will continuously vary in multiple directions. This makes occurrences of self-arrest unlikely to persist.
  • Continuous complex motion of the abutment element over the associated abutment surface will also rub dirt away that could affect the friction properties and contribute to self-locking.
  • the drive spindle is of telescopic nature. This property is relevant in combination with shaver designs, in which the cap-and-cutting unit-system resides in contour-following sections, while the driving mechanism resides in a stationary section. In these designs, the cutting units are driven by a telescopic spindle that contracts and expands with the contour-following movements. With a shaver according to the invention contour-following movements will occur during usage, and the abutment element will move up and down along with the associated slanted abutment surface of the drive spindle. By this, dirt that could affect the working of the self-adaptive mechanism is continuously rubbed off.
  • the coupling formed by the first and second coupling elements may be configured for transmitting torque and for transmitting force in the axial direction of the drive spindle, but not to transmit any other mechanical loads.
  • the abutment surface extends helically relative to the axis of rotation.
  • a helical orientation of the abutment surface is the most obvious design to obtain a force component parallel to the axis of rotation and directed towards the internal cutting member, although other configurations are possible.
  • the abutment element comprises a boss.
  • the drive spindle comprises a mechanical spring arranged to bias the second spindle part relative to the first spindle part in a direction towards the internal cutting member.
  • the spring provides an additional axial force that acts as an offset to the closing force resulting from the interaction between the abutment elements and the abutment surfaces. Together these forces provide the closing force onto the cutting elements.
  • the spring ensures extension of the spindle and a minimum closing force.
  • the first spindle part comprises a cavity
  • the second spindle part is partially received in said cavity and displaceably guided by said cavity so as to be displaceable relative to the first spindle part in the axial direction.
  • the mechanical spring is arranged in the cavity for exerting a biasing force on the second spindle part directed towards the internal cutting member.
  • the angle ⁇ at which the abutment surface is arranged may be used as a design parameter to set the ratio between the torque and the axial force.
  • the offset of the axial force can be tuned by the properties of the enclosed spring.
  • the angle ⁇ is greater than 0° and smaller than 90°.

  • the angle ⁇ is between 20° and 70°.
  • Friction forces between the first spindle part or driven part and the second spindle part or driving part have been neglected so far, since such friction forces are inherent in any kind of drive spindle consisting of two parts movable with respect to each other.
  • the angle ⁇ should have a minimum value so that dynamic friction forces are overcome so that there will be a continuous movement of the first spindle part with respect to the second spindle part under pressure exerted by the cutting unit.
  • the friction is dynamic due to the angle between the first and second spindle parts.
  • the minimum angle ⁇ to overcome dynamic friction forces is estimated to be on the order of 3° to 8°.
  • the angle varies along an axial extension of the drive spindle.
  • the relationship between the torque and the closing force can then be varied by the position of the shaving head.
  • the cutting unit is moveably suspended relative to the support structure by means of a suspension structure such that, as a result of a motion of the cutting unit relative to the support structure allowed by the suspension structure, the first coupling element is displaced in the axial direction whereby the first and second spindle parts are displaced relative to each other in the axial direction, and wherein the angle ⁇ of the abutment surface varies in the axial direction.
  • the cutting unit comprises a supporting member for supporting the external cutting member, and wherein the suspension structure comprises a pivot structure pivotally connecting the supporting member to the support structure.
  • the hair cutting appliance comprises at least two cutting units and at least two drive spindles as described with respect to any of the embodiments of the hair cutting appliance here before, wherein each of the at least two drive spindles is arranged to be couplable to a respective one of the at least two cutting units.
