Definitions

  • the present invention relates to a razor for supporting a detachable blade unit.
  • a razor which is used for wet shaving, has a handle, a head piece and a coupler disposed on the head piece, to which a blade unit can be attached.
  • Razors designed for many shaves allow replacement of the blade unit because the razor blades disposed therein wear while the shaver itself is reusable.
  • the coupling units of Mehrwegrasieren must be permanently functional, but should not increase the assembly costs and the cost of the shaver too much.
  • the coupling unit must allow a movable attachment of the blade unit, so that it can adapt to the skin contours during shaving.
  • the coupling unit must ensure a predetermined position of the blade unit relative to the handle in order to achieve a high-quality shaving result.
  • the coupling unit requires both supporting and leading elements that have to apply additionally defined spring forces on the blade unit. In known razors this has so far led to very complex coupling units, with a large number of parts and the resulting high production costs and high error rate.
  • the blade unit If the blade unit is to be released from the spring clip, the user must simultaneously press two side buttons to swivel the brackets to each other can. The operability of this release mechanism is difficult if the change of the blade unit is to be made with one hand. The blade unit also receives no further lateral guidance from the spring clip.
  • a razor with a detachable blade unit is known.
  • two support arms of the shaver engage in the blade unit.
  • the support arms have bearing shells at their front ends, which receive the blade unit on holders provided for this purpose. Since the brackets engage in this position, the blade unit is secured against lateral displacement.
  • a tensioned by a coil spring ram acts on the blade unit to store them resiliently.
  • the support arms are released by pressing an operating button, the then swivel inwards, since on both sides a leaf spring acts on the support arms.
  • the coil spring acting on the plunger is also displaced in the direction of the blade unit, so that the ejection of the blade unit is forced.
  • the coupling unit of this shaver consists of at least seven parts, resulting in a high production cost and a high probability of failure. Since the lateral guidance of the blade unit (parallel to the cutting edges) takes place exclusively via the support arms, the support arms must be secured within the coupling unit against pivoting. The blade unit can tilt slightly by the storage in the bearing shells during shaving, so that the suspension of the blade unit by the plunger is only partially effective.
  • the GB 2 078 589 A relates to a razor with a detachable blade unit, which is held by two pivotally mounted arm structures whose pivot axes are fixedly connected to the housing.
  • a spring-loaded plunger acts, which urges the blade unit in a middle position.
  • the pivotal movement of the arm construction is determined by a movement of the control knob.
  • pivotal movement of the arm structures into recesses in the control knob is prevented.
  • the operating button is pressed in the direction of the blade unit, which at the same time move the rear parts of the arm structures in this direction and the pins are pivoted outwards.
  • the lateral guidance of the blade unit takes place exclusively over the arms.
  • a shaver with a detachable blade unit is described, the head of which has a fork-like support with a base plate and two integral lateral arms.
  • a displacement unit is arranged with an elastic tongue for operating the holder.
  • a strip is arranged to guide the central part of the holder in the longitudinal direction in a guide groove in the housing of the shaver.
  • the arms are guided by bolts on their underside in oblong holes.
  • On the base plate is still a U-shaped spring, which faces the blade unit. The U-shaped spring corresponds with the blade unit with respect to the shape of its head, so that it is urged into a predetermined position.
  • the holder is pushed in the direction of the blade unit, at the same time the U-shaped spring is moved forward.
  • the user exerts a pressure in the direction of the blade unit on the tongue.
  • the direction of movement of the base plate including the tongue is determined by the guide groove.
  • the arms are elastically connected to the base plate. Their direction of movement is determined by the elongated holes, so that they are pushed simultaneously during the forward movement to the outside and release the blade unit. The absorption of the forces acting on the blade unit along the axis of rotation takes place via the arms.
  • the object of the present invention is therefore to provide an improved razor for supporting a detachable blade unit, which allows a secure attachment of the blade unit to a coupling unit, easy one-handed operation when changing the blade unit, the assembly effort in the manufacture of the shaving minimizes apparatus and ensures a defined storage of the blade unit in a predetermined shaving position, which also along the cutting edges occurring forces must not lead to an unwanted release of the blade unit of the coupling unit.
  • a significant advantage of the razor according to the invention is that the manufacturing and assembly costs are minimal.
  • the entire coupling unit can be due to the one-piece design as a plastic injection molded part in a single operation produce. Since not several items must be completed to the coupling unit, the assembly effort is reduced to the insertion of the plastic injection molding in the head of the razor and the local attachment, these operations can be automated and largely done without manual activities.
  • the coupling part can be broken during assembly at a predefined predetermined breaking point in two parts, if appropriate for mounting.
  • the functional unit remains in this approach e.g. obtained technically by a latching connection, which reassembles the separated parts in the region of the predetermined breaking point.
  • a further significant advantage of the razor design according to the invention is that the two support arms of the coupling unit with the bearing elements arranged thereon predominantly serve to provide the pivot bearing for the blade unit, so that the blade unit can be pivoted about an axis of rotation determined by the position of the bearing elements.
  • the displacement forces occurring along the axis of rotation in the longitudinal direction of the cutting edges of the blade unit need not be absorbed by the bearing elements and the support arms. Therefore, the spring forces can be made low, which should pivot the support arms in their rest position, so that the bearing elements engage in the complementary pivot bearing of the blade unit.
  • An advantage of a modified embodiment of the razor is that by lateral guide elements on the support element, the repeatedly carried out during operation attachment of the blade unit to the coupling unit for the user is facilitated.
  • it can come about by the spring force far projecting support element when attaching the blade unit, that this engages next to the actual sliding surface when you first introduces a support arm laterally and then pivoted laterally the handle to the cutting unit to mount the second arm. If instead one of the two smooth mating surfaces of the blade unit and the support element is replaced by laterally mounted guide elements in the improved embodiment, such a detrimental attachment of the blade unit can be prevented.
  • sliding forces are primarily absorbed by the support member which is disposed between the bearing elements and may be attached either to the coupling unit or complementary to the blade unit.
  • a biasing force is exerted on the blade unit via the support element in order to pivot the blade unit into a rest position.
  • a preferred embodiment is characterized in that the two support arms are mounted via a hinge in the head piece and that there is a stop edge between the hinge and the outer end of the support arm, which can engage an actuating web of the release element.
  • pivoting of the support arm substantially along the axis of rotation occurs in this way, so that the blade unit is released and due to the introduced via the support element Preload force is automatically ejected.
  • This non-rigid connection between the actuating web and the support arms also prevents the improper operation of the support arms can lead to the destruction of the release function.
  • the actuating webs are preferably integrally connected via a release element with an actuating pin protruding from the head piece, on which on the top of the head piece, an operating knob is mounted.
  • the support element is integrally formed with a plunger carrier, which is displaceable approximately perpendicular to the axis of rotation in the head piece. In the direction of the axis of rotation of the plunger carrier and the adjoining plunger can not be moved.
  • a biasing spring element which is also formed integrally with the plunger carrier.
  • the headpiece of the shaver has an upper shell connected to the handle, in which the coupling unit is inserted.
  • This upper shell is closed at the bottom by a lid, which can preferably be attached by ultrasonic welding or gluing.
  • the handle of the razor has recesses in which a second plastic component is introduced, which is for ensures a secure grip even when wet.
  • a second plastic component is introduced, which is for ensures a secure grip even when wet.
  • Fig. 1 shows a perspective view of a razor according to the invention.
  • the razor has a handle 1, which merges into a head piece 2.
  • a coupling unit 3 is arranged, whose components are described in more detail below.
  • the coupling unit 3 carries a blade unit 4, which is detachably attached to the coupling unit.
  • the coupling unit 3 engages the back of the blade unit 4, while on the front of the blade unit 4, the cutting edges of one or more razor blades are accessible.
  • an operating button 5 which can be displaced by the user preferably with the thumb towards the blade unit 4 in order to actuate the coupling unit and to release the blade unit for replacement.
  • the forces to be overcome by the user for this actuation are generally dimensioned so that one-hand operation remains possible. The user does not have to touch them when changing the blade unit, so that risks of injury are excluded.
  • the action of the operating knob 5 on the coupling unit will be described below.
  • the handle 1 is integrally connected to an upper shell 6 of the head piece 2 and consists of a first hard plastic component.
  • the handle 1 and optionally parts of the head piece 2 have recesses in which a second plastic component 7 is embedded.
  • the production of two-component plastic parts is generally known to the person skilled in the art, so that a detailed explanation can be dispensed with.
  • the second plastic component usually has special haptic properties and is softer than the first plastic component. The operating properties, in particular the grip of the shaver can be improved.
  • the handle 1 has a substantially square cross-section, which can be attached to the longitudinal sides of waistings 8. It has been found that the choice of a substantially square cross-section increases the versatility of the shaver in terms of the user-desired guidance and manageability. Since the shavers are used by different users who use very different shaving techniques, the selected cross-sectional shape of the handle provides optimal operation for many users. In modified embodiments, the shape of the handle and the head piece can be tailored to specific user groups or desired designerische aspects.
  • Fig. 2 shows in a detailed view of the head piece 2, wherein the lid has been removed from the underside of the upper shell 6, so that the mounted within the head portion of the coupling unit 3 is visible.
  • the coupling unit comprises two support arms 10, each having a bearing pin 11 as a bearing element at its outer ends. As far as the bearing pins 11 are aligned, extends the dashed line rotation axis 12 about which the blade unit is pivotally, in the axial direction of the journals. Other versions with a displaced axis of rotation are conceivable.
  • a support element is provided, which is assigned in this embodiment, the coupling unit, also protruding from the head piece 2 and is integrally connected to a arranged within the head piece biasing spring element 13.
  • the support element is designed here as a plunger 14, which is connected to a plunger carrier 15, which in turn is mounted in the head piece.
  • the plunger carrier 15 has two slots in which guide pin 16 of the upper shell 6 engage.
  • the plunger carrier can be moved in the axial direction of the head piece, wherein the displacement is limited by the slots in the plunger carrier and the biasing spring element 13 moves the plunger 14 as far as possible to the outside when no external force acts.
  • Fig. 3 shows the coupling unit 3 again in a detailed drawing, wherein the blade unit 4 is shown coupled and the head of the shaver is not shown.
  • Fig. 2 Here is a view from above selected so that the support arms 10 are above the plunger carrier 15.
  • Fig. 3 It can also be seen that in each support arm 10, a bore 17 is arranged, which forms a pivot joint together with the guide pin 16 of the head piece, so that the support arm can be pivoted about the axis of this joint.
  • a release element 20 is provided, which comprises two actuating webs 21 in the illustrated embodiment.
  • the actuating bars 21 engage behind a respective stop edge 22 on the support arm 10. Since the stop edge 22 is disposed between the bearing pin 11 and the pivot located in the bore 17, a force introduced by the actuating bar causes the pivoting of the support arms to the outside.
  • the release element 20 is moved in the axial direction of the head piece on the blade unit 4.
  • the blade unit automatically springs out of storage when the bearing pins 11 are moved out of the pivot bearings. Thus, it is unnecessary for the user to touch the blade unit, thereby greatly reducing the risk of injury to the sharp razor blades.
  • the force to be overcome for pivoting the support arms is designed so small that one-hand operation remains possible.
  • Fig. 3 Out Fig. 3 is also apparent that the plunger 14 of the support member engages a sliding surface 25 of the blade unit.
  • the sliding surface 25 is adapted to the plunger so that a displacement parallel to the cutting edges of the blade unit is not possible.
  • the plunger is for this purpose fork-shaped at its free end, so that the sliding surface 25 is encompassed by this fork. This design also ensures that the plunger 14 can not be positioned next to the sliding surface 25 during the attachment of the blade unit and jammed there.
  • Fig. 3 is also apparent that the release member 20 is still an actuating pin 26 is formed, which extends through the upper shell 6 in the assembled state through which and the operating knob 5 is attached.
  • the release element 20 is further integral with a return spring element 27, via which the rest position of the release element 20 is fixed.
  • the return spring member 27 also aids in the sliding back of the release member 20 after the user has activated the release member via the operation knob 5 to swing the support arms 10 outwardly.
  • Fig. 3 clearly visible that the two support arms 10 merge at their inner ends in a spiral spring element 30 which extends, for example, U-shaped between the support arms.
  • the support arms With the help of the spiral spring element 30, the support arms are pivoted into a rest position, in which the bearing pins 11 engage in the pivot bearings of the blade unit.
  • the spring constant of the spiral spring element 30 can be kept relatively small, since no displacement forces occurring along the blade unit have to be absorbed by the support arms. These displacement forces are largely derived via the plunger 14 in the head and thus in the handle. A longitudinal displacement of the blade unit is thus excluded, so that the bending spring element 30 is only responsible for pivoting the bearing pin 11 via the support arms 10 in its engaged position in the pivot bearings of the blade unit.
  • the spiral spring element can also be shaped differently. Ultimately, only the provision of a corresponding spring force is required. Of course, these modifications also apply to the biasing spring element and the return spring element.
  • Fig. 4 shows a side view of the front portion of the head piece 2 with the protruding from this free ends of the support arms 10 and the plunger 14. From this illustration is apparent from the dashed lines drawn on the one hand, that the free ends of the support arms 10 can be angled relative to the head piece or the handle. In this way, the rest position of the blade unit can be predetermined. It is known to the person skilled in the art that in order to achieve a good shaving result, the plane of the cutting blades must be brought into a predetermined angular position with respect to the longitudinal axis of the handle. By different bends of the support arms 10 different positions of the blade unit relative to the handle can be adjusted, so that by adapting the coupling unit, in particular the support arms, different products that use similar handles can be equipped.
  • the point of application of the plunger 14 should preferably not lie in the axis of rotation 12, which runs between the two bearing journals 11 of the support arms 10. In this way, it is possible to impose a bias on the blade unit on the plunger 14, so that the blade unit is pivoted in a defined rest position.
  • the direction vector of the impressed biasing force does not pass through the axis of rotation 12.
  • the rest position of the blade unit can be adjusted. The magnitude of this biasing force depends on the spring rate of the bias spring member 13 and the biasing path resulting from the position of the plunger.
  • the plunger 14 When pivoting the blade unit 4, the plunger 14 can be moved transversely to the axis of rotation to allow a relatively free rotation of the blade unit about the axis of rotation.
  • the permissible pivoting range can be determined by ramp surfaces 31 on the support arms 10 and limit stops at the blade unit to a desired range.
  • Fig. 5 shows a plastic injection molded part, which unites all the elements of the coupling unit 3 in itself and forms the coupling unit 3 after installation in the head of the razor. Due to the special arrangement of the individual components, it is possible to produce the complete coupling unit in a single injection process and also automated to install in the header. On a variety of separate, to be mounted items can be completely eliminated.
  • Fig. 5 It can be seen that the support arms 10, which are connected to each other via the spiral spring element 30, are made in one piece.
  • a film hinge 35 is provided, which connects to a second section of the coupling unit, which comprises the plunger carrier 15 and the release element 20.
  • the biasing spring element 13 and the return spring element 27 extend to the return spring element 27, the release element 20 is coupled, while integrally connected to the biasing spring element 13 of the plunger carrier 15 with the plunger 14.
  • the support arms 10 are folded with the spiral spring element 30 via the plunger carrier 15.
  • the pivot axis extends through the film hinge 35.
  • the selected thickness and stiffness of the film hinge 35 determines whether the hinge breaks during assembly or is only bent. In the case of a deliberately induced fracture, the positioning of the two resulting parts in the further assembly can continue via the groove 37 and the pin 38.
  • the film hinge 35 is designed so deformable that the coupling unit can be integrally mounted as a unit.
  • Fig. 6 shows a modified embodiment of the coupling unit 3, which is also designed as a one-piece plastic injection molded part.
  • the essential difference from the previously described embodiment is that the release element 20 is located directly between the support arms 10 and that the actuating webs 21 are firmly connected to the support arms 10. An axial displacement of the actuating element 20 also causes a spreading of the support arms 10. In this case, a separate return spring element for the actuating element can be dispensed with.
  • Fig. 7 shows the front portion of a modified embodiment of the shaver.
