Definitions

  • This invention relates to safety razors and it is particularly concerned with safety razors in which a safety razor blade unit including at least one blade with a sharp cutting edge is mounted on a razor handle to be movable pivotally relative to the handle under forces exerted on the blade unit in the course of shaving.
  • a blade unit may have a plurality of blades, for example two, three, four or more blades, with straight parallel cutting edges disposed for contact with the skin between guard and cap surfaces also provided on the blade unit.
  • the guard may include a strip of elastomeric material with a surface configuration, for example upstanding projections such as in the shape of fins, to produce a desired interaction with the skin as the blade unit is moved across the skin in the performance of a shaving stroke.
  • the cap surface may include a strip of material containing a shaving enhancement product, such as a lubricant, which can gradually leach out of the strip material for application to the skin during shaving.
  • a shaving enhancement product such as a lubricant
  • the safety razor blade unit may be mounted detachably on the razor handle to allow the blade unit to be replaced by a fresh blade unit when the blade sharpness has diminished to an unsatisfactory level.
  • the blade unit can be connected permanently to the handle with the intention that the entire razor should be discarded when the blade or blades have become dulled. Detachable and replaceable blade units are commonly referred to as shaving cartridges.
  • the present invention relates to safety razors with blades units arranged to be capable of pivoting movement about an axis substantially perpendicular to the cutting edges of the blade(s).
  • the pivoting motion allows the blade unit to more easily follow the skin contours so that the exact angle at which the handle is held relative to the skin is less critical to achieving a good shaving performance and efficiency.
  • Razors with pivotal blade units have been successfully marketed for many years.
  • the traditional pivot axis which usually extends parallel to the cutting edges of the blades, can be defined by a pivot structure by means of which the handle is connected to the blade unit.
  • the blade unit may include an attachment member to which a frame or housing incorporating the blade or blades and other skin contacting parts is pivotally connected.
  • a blade unit of this form described in WO 97/37819 A2 has an attachment member in the general form of a yoke with a hub for engagement with the upper end of the handle and a pair of oppositely directed arms provided with pivot journals at their ends for engagement in sockets provided at the ends of the frame. Retention clips are applied around the respective ends of the frame to maintain the pivot journals within the sockets.
  • a razor having a blade unit mounted for pivotal movement about a single axis substantially parallel to the blade edges has been proposed also in WO 2005/049289 A1 .
  • the blade unit is biased to a rest position by a magnetic return force generated by magnets.
  • the pivotal movement about the single axis substantially parallel to the blade edges provides some degree of conformance with the skin allowing the blade unit to more easily follow the skin contours during shaving.
  • the blade unit often disengages from the skin during shaving as it has limited ability to pivot about a single axis.
  • the present invention addresses this drawback by employing a magnetic return force about a pivot axis that is substantially perpendicular to the blade edges allowing for improved conformance of the blade unit with the users skin during shaving.
  • a safety razor comprising a handle and a blade unit with a guard, a cap and at least one blade.
  • the blade unit is mounted to the handle for movement relative thereto about a pivot axis substantially perpendicular to the at least one blade for following the skin contours during shaving.
  • the blade unit has a rest position towards which the blade unit is biased by a return force when pivoted about the pivot axis away from the rest position.
  • the return force comprises a magnetic force generated by a set of magnetic elements that are moved relative to each other in response to pivotal movement of the blade unit about the pivot axis substantially perpendicular to the at least one blade. The return force increases in magnitude as the blade unit pivots away from the rest position.
  • a safety razor comprising a handle and a blade unit with a guard, a cap and at least one blade.
  • the blade unit is mounted to the handle for movement relative thereto about a first pivot axis and a second pivot axis for following the skin contours during shaving.
  • the blade unit has a first rest position and a second rest position towards which the blade unit is biased by a first return force and a second return force.
  • the first return force occurs when the blade unit is pivoted about the first pivot axis away from the first rest position.
  • the first return force comprises a magnetic force generated by a first set of magnetic elements that are moved relative to each other in response to pivotal movement of the blade unit about the first pivot axis substantially parallel to the at least one blade.
  • the first return force increases in magnitude as the blade unit pivots away from the first rest position.
  • the second return force occurs when the blade unit is pivoted about the second pivot axis away from the second rest position.
  • the second return force comprises a magnetic force generated by a second set of magnetic elements that are moved relative to each other in response to pivotal movement of the blade unit about the second pivot axis which is distinct from said first pivot axis.
  • the second return force increases in magnitude as the blade unit pivots away from the second rest position.
  • the magnetic force can be conveniently generated by magnetic elements that are moved relative to each other in response to pivotal movement of the blade unit relative to the handle, and interact repulsively to urge the blade unit to the respective rest positions.
  • the first set of magnetic elements are arranged to generate a repulsive magnetic return force for urging the blade unit to the first rest position.
  • the second set of magnetic elements are arranged to generate a repulsive magnetic return force for urging the blade unit to the second rest position.
  • the first set of magnetic elements may comprise a first magnetic element and a second magnetic element and the first magnetic element is mounted to the blade unit adjacent the cap.
  • the first set of magnetic elements may comprise more than two magnetic elements, e.g., two sets of opposed pairs.
  • the blade unit is pivotally carried by a pair of opposed arms extending from a hub, and the second magnetic element is positioned at the hub.
  • the first pivot axis is preferably positioned in front of the at least one blade.
  • the first pivot axis may be located below a plane tangential to the guard and cap.
  • the magnetic elements which produce the first and second return forces are so arranged that as the angle of pivoting about the first and second pivot axes from the first and second rest position increases, the spring rate characteristic of the magnetic return force increases smoothly.
  • a further advantage of the invention is that the strength of the return forces can easily be modified by using magnetic elements of different magnetic strength.
  • the first pivot axis is preferably positioned to be substantially perpendicular to the second pivot axis.
  • the magnetic elements can conveniently be permanent magnets, at least one of the magnetic elements can comprise an electromagnetic element, in which case a control device can be provided for adjusting the electric magnetizing current delivered to the electromagnetic element.
  • a sensor may, for example, be provided to sense the pivotal displacement of the blade unit from the rest position and the control device can be responsive to an output from the sensor.
  • the second set of magnetic elements preferably comprises a third magnetic element, a fourth magnetic element and a fifth magnetic element.
  • the second set of magnetic elements may comprise a sixth magnetic element.
  • the third magnetic element may be mounted to the handle and the fourth and fifth magnets may be mounted to the blade unit.
