Definitions

  • the invention relates to a razor having a plastic handle and guard.
  • the razor is provided with a rod disposed axially of the handle and movable lengthwise in respone to rotation of a nut to open and close the cap means.
  • Cam means are provided and are operative in response to rotation of the nut, to close the cap means, to exert an inwardly directed pressure on the rod to prevent further axial movement of the rod, whereby to prevent accidental deformation of the plastic guard after closing of the top means.
  • plastic guard means Perhaps the most serious problem faced in the use of plastic guard means is that the plastic is subject to deformation when subjected to pressure.
  • the cap means and cap closing mechanism of a razor comprise metal parts. After the cap means is closed, it frequently happens that the user continues to operate the cap closing mechanism to insure secure closure. However, continued closing pressure by the cap means upon the razor blade is exerted upon the guard means, and when the guard means is plastic the guard means frequently deforms undesirably, altering the guardblade cap geometry and dimensional relationships, often resulting in a less than desirable shave.
  • a further object of the invention is to provide such a razor having means for preventing the cap means from exerting deforming pressure upon the plastic guard means.
  • afeature of the present invention is the provision of a safety razor having a plastic handle and guard portion, rod means extending through the handle and guard portion, the rod means being connected at one end to razor cap means and at the other end tov actuator means on the handle, the rod being movable responsive to movement of the actuator means to open and close the cap means, and cam means associated with the handle and acutator means and operative, in response to operation of the acutator means, to close the cap means, to exert pressure inwardly on the rod means to prevent further axial movement of the rod means, thereby to prevent further razor cap means closure.
  • FIG. 1 is an exploded perspective view showing the components of one form of razor illustrative of an embodiment of the invention
  • FIG. 2 is a generally sectional side elevational view
  • FIG. 3 is similar to FIG. 2 but shows the cap means in a closed position
  • FIG. 4 is a side, generally sectional view of a portion of the razor handle, showing the operation of a cam means to prevent further axial movement of the cap closing mechanism;
  • FIG. 5 is a front elevational view, partly broken away
  • FIG. 6 is a top plan view, partly broken away.
  • FIG. 7 is a side elevational view of the head portion of the razor.
  • the invention comprises a safety razor having a plastic handle portion 2 and a plastic guard portion 4.
  • the handle and guard portions 2, 4 may be formed as a single molded plastic handle and guard portion 6, as illustrated in the drawings.
  • the handle and guard portion 6 is provided with a central bore 8 in which is disposed a rod 10 which preferably is provided with a portion 1 1 having a rough exterior surface.
  • a first end 12 of the rod 10 is connected to a bridge member 14 to which there are rigidly attached end members l6, 18. On the end members 16, 18 there are pivotally mounted razor cap means 20, 22.
  • the bridge member 14, and the end members 16, 18 are well known in the art, in structure and operation, and will be referred to hereafter as a cap closing mechanism.
  • the cap means 20, 22 are caused to open and when the rod 10 is caused to move downwardly, the cap means are caused to close.
  • a second end 24 of the rod 10 includes a threaded portion 26 which receives an internally threaded actuator or nut 28.
  • the handle portion 2 includes a split-ring extension 30 having a collar portion 32.
  • the actuator 28 is provided with a recess 34 for receiving the handle extension 30.
  • the recess 34 includes a circular groove 36 for receiving the collar 32.
  • the extension 30 is provided with a bevelled external surface 38 and that the actuator recess 34 is provided with a correspondingly bevelled interior surface 40.
  • the groove 36 is wider than the collar 32, thereby providing room for limited movement of the collar 32 in the groove 36.
  • the rod 10 may be provided with a washer 42 disposed in a second actuator recess 44 which may be covered by an end plate 46.
  • the nut 28 is rotated by an operator to cause the rod 10 to move axially upwardly, as viewed in FIG. 2, to cause the cap members 20, 22 to open, as
  • a razor blade B may then be placed upon the guard portion 4.
  • the nut 28 is rotated in the opposite direction, causing the rod to move axially downwardly, as viewed in FIG. 3, until the cap members 20, 22 are seated on the blade B.
  • a razor comprising a plastic handle, a plastic guard joined to said handle, a cap for holding a blade in position on said guard, longitudinally extending means movably mounted on said handle for opening and closing said cap relative to said guard, and cam means for limiting the movement of said movable means after the cap has been closed, said cam means exerting a radial inward pressure on said movable means to prevent further movement thereof.
  • said movably mounted means includes an axially movable rod, and said cam is operative, upon closure of said cap, to prevent further axial movement of said rod, thereby to prevent further cap closing operation of said movably mounted means.
  • a razor comprising a plastic handle portion, a plastic guard portion joined to said handle portion, said handle and guard portion having a bore extending axially therethrough, a rod disposed in said bore, a first end of said rod being connected to razor cap means, a second end of said rod being connected to actuator means disposed on said handle portion, said rod being movable axially in said bore responsive to movement of said actuator means whereby to open and close said cap means, and cam means associated with said handle portion and said actuator means and operative in response to operation of said actuator means to close said cap means to exert pressure inwardly on said rod, whereby to prevent further axial movement of said rod.
  • a razor comprising a plastic handle portion, a plastic guard portion connected to said handle portion, said handle and guard portion having a bore extending axially therethrough, a rod disposed in said bore, first end of said rod being connected to razor cap means, a second end of said rod being connected to actuator means disposed on said handle portion, said rod being movable axially in said bore responsive to movement of said actuator means to open and close said cap means, and cam means associated with said handle portion and said actuator means, said cam means being operative in response to closing operation of said actuator means increasingly to exert pressure inwardly on said rod, whereby after initial seating of said cap means, said cam means operates to increasingly resist application of further closing pressure in said closing operation, and after completion of the closing operation operates to prohibit further closing of said cap means, whereby to prevent deformation of said guard portion.
