Definitions

  • the present invention relates to a wet shaving system.
  • the present invention has particular applicability in wet shaving systems having a pivoting razor cartridge which is connected to a handle by a connector.
  • Many conventional shaving razor systems have handle heads configured to permit rotation of a replaceable razor cartridge about a pivot point. Some arrangements permit free rotation of the razor cartridge through a predetermined range about pins attached to the head and engaging an underside of the razor cartridge. Other types include arcuate bearings formed in the handle head, which mate with hooks on the underside of the razor cartridge. The arcuate bearings determine the range of pivoting motion of the cartridge. The pins or arcuate bearings must be spring-loaded and movable to enable removal and replacement of the razor cartridge.
  • Some handle heads spring-load or bias the pivotally mounted razor cartridge toward a neutral position, such as at or near the midpoint of the predetermined range, allowing the cartridge to be displaced away from the neutral position in one direction, and to then move back to the neutral position, using complicated spring configurations or requiring unique or specialized razor cartridges.
  • Still other handle heads have complex spring assemblies which extend from within the handle head to the front of the handle and contact the underside of the pivotally mounted razor cartridge to bias the cartridge to a "home" position.
  • Conventional razor mounting arrangements require a complex handle head, a complex razor cartridge, or both. Thus, there is a need for a simplified, inexpensive methodology for mounting a conventional razor cartridge on a handle.
  • An advantage of the present invention is a shaving system having a simple handle with no moving parts, a simple razor cartridge, and a single-piece connector for removably connecting the cartridge to the handle, for providing pivot mounting of the cartridge, and for providing biasing of the cartridge to a home position.
  • a shaving system comprising a handle, a razor cartridge having at least one blade, and a connector.
  • the handle has a handle body and a handle extension at the front of the handle body.
  • the handle extension has a horizontal bottom wall, a pair of spaced-apart vertical walls, and a pair of top walls extending inward from the vertical walls.
  • the connector comprises a central body, a pair of yokes extending forward from the central body, each yoke having a cartridge support at its distal end for supporting the razor cartridge, and a handle-attachment portion extending rearward from the central body.
  • the handle-attachment portion has a pair of guide walls for fitting between the vertical walls of the handle extension, and a pair of latches for engaging a corresponding pair of notches in the top walls of the handle extension, to removably retain the connector on the handle extension between the horizontal, vertical and top walls.
  • FIG. 1 Another aspect of the present invention is a connector for supporting a razor cartridge, and for connecting to a razor handle having a handle body and a handle extension at the front of the handle body, the handle extension having a horizontal bottom wall, a pair of spaced-apart vertical walls, and a pair of top walls extending inward from the vertical walls.
  • the connector comprises a central body, a pair of yokes extending forward from the central body, each yoke having a cartridge support at its distal end for supporting the razor cartridge, and a handle-attachment portion extending rearward from the central body, the handle-attachment portion having a pair of guide walls for fitting between the vertical walls of the handle extension, and a pair of latches for engaging a corresponding pair of notches in the top walls of the handle extension, to removably retain the connector on the handle extension between the horizontal, vertical and top walls.
  • a further aspect of the present invention is a razor handle having a handle body and a handle extension at the front of the handle body, the handle extension having a horizontal bottom wall, a pair of spaced-apart vertical walls, and a pair of top walls extending inward from the vertical walls, the top walls each having a notch at their extreme rear end for engaging a latch in a connector to removably retain the connector on the handle extension between the horizontal, vertical and top walls.
  • a still further aspect of the present invention is a dispenser for dispensing a razor cartridge/connector assembly, the dispenser comprising a bottom wall having a support for supporting a lower portion of the connector, a vertical tab for extending into a chamber at an underside of the connector, and a snap for biasedly engaging an outside wall of the connector to retain the cartridge/connector assembly in the dispenser.
  • a rear wall is attached to the bottom wall
  • a cut-down front wall is attached to the bottom wall
  • a pair of opposed side walls are attached to the bottom wall, the rear wall and the front wall.
  • the vertical tab and the snap are arranged such that the cartridge does not contact the bottom wall, the rear wall, the front wall or the side walls when it is retained in the dispenser.

  • a razor cartridge 30O 5 such as a triple-blade cartridge whose blades are conventionally mounted using a sandwich construction, is pivotally mounted to connector 100. Illustrations of such a cartridge are shown at Figs. 1 IA-B.
  • the pivotal mounting of cartridge 300 to connector 100 will now be described with reference to Figs. 1-5. As shown in Figs.
  • connector 100 has a central body 105 and a pair of yokes 110 extending forward from body 105.
  • Each yoke 110 has a boss 115 at its distal end comprising a pair of opposed bearing sections 120 for rotatably supporting one of a pair of platform pivot pins 310 extending from cartridge platform 305 (see Fig. 3). Pins 310 are snapped into place between bearing sections 120 by a slight flexing of yokes 110 towards each other.
  • Each boss 115 further comprises a cartridge return spring 125, a rearward stop 130 and a forward stop 131.
  • cartridge 300 When cartridge 300 is mounted on connector 100 via pins 310 and bearing sections 120, springs 125 bear against an upper surface of cartridge platform 305 to bias cartridge 300 downward against rearward stops 130.
  • Rearward stops 130 provide a "home" position for cartridge 300 by preventing further downward cartridge pivoting (see Figs. 3 and 4).
  • Springs 125 are adjacent to rearward stops 130 at the home position.
  • cartridge 300 is pivoted upward, as in response to shaving forces, springs 125 flex upward to provide controlled movement of cartridge 300, as shown in Fig. 5, then force cartridge 300 back to the home position as the shaving forces are lessened or removed.
  • Forward stops 131 limit upward pivoting of cartridge 300 (see Fig. 5).
  • cartridge 300 includes three blades 320a-c, a guard 330 having a single row of dimples (not shown), and a cap 350.
  • Cartridge platform 305 includes support bars 305b, 305c.
  • Connector 100 comprises a connector body 105 having a front yoke-supporting portion 105a and a rear handle-attachment portion 105b of reduced width.
  • Yoke-supporting portion 105a has a solid rear wall 145.
  • Attachment portion 105b is made up of a horizontal wall 135 and a pair of vertical walls 140 that depend from horizontal wall 135 (see Figs. 2A and 2C).

  • Each guide wall 150 has a top surface 150a generally parallel to, and lower than, the top surface of horizontal wall 135, thereby forming a step between guide wall top surface 150a and the top surface of wall 135.
  • One end of each guide wall 150 is attached to rear wall 145 of yoke-supporting portion 105 a.
  • a pair of latches 150b is located at the rear of walls 140 and extends above guide wall top surface 150a toward the top surface of horizontal wall 135.
