Definitions

• the invention relates to wet shaving systems, and is directed more particularly to a razor handle suitable for use in such a system.
• An object of the present invention is to provide a razor handle suitable for use with shaving units, or cartridges, of the type disclosed in the above referred to U.S. Patent Application Serial No. 352,150, the razor handle comprising an improvement over the razor handle disclosed in the above referred to U. S. Patent Application Serial No. 352,146.
• a feature of the present invention is the provision of a razor handle comprising an elongated grip portion, a neck portion extending from one end of the grip portion at an angle thereto, a protrusion extending from a free end of said neck portion, a web means interconnecting said protrusion and said free end of said neck portion, said web being of lesser thickness than said protrusion to provide recess means between said protrusion and said free end of said neck portion, and plunger means disposed in said neck portion, a first end of said plunger means being accessible from said grip portion and a second end of said plunger means being proximate said remote end of said neck portion, said plunger means being movable.
• FIG. 1 is a side elevational view of one form of razor handle illustrative of an embodiment of the invention
• FIG. 2 is a rear elevational view thereof
• FIG. 3 is similar to FIG. 2, but showing the razor handle in combination with a shaving cartridge
• FIG. 4 is a sectional view taken along line IV - IV of FIG. 3;
• FIGS. 5 - 7 are similar to FIG. 4, but showing a portion of the illustrative handle in various operating positions and in combination with a shaving cartridge. DESCRIPTION OF THE PREFERRED EMBODIMENT Referring to the drawings, it will be seen that the illustrative razor handle includes an elongated grip portion 2 and a neck portion 4 extending from one end of the grip portion and disposed at an angle to the grip portion.
• the protrusion 6 Extending from an end 3 of the neck portion 4 remote from the grip portion 2 is a protrusion 6.
• the pro trusion 6 has first and second major planar surfaces 8, 10 extending from a free end 12 of the protrusion, at which the surfaces 8, 10 are closest to each other, to a base portion 14, at which the surfaces 8, 10 are farthest apart.
• Substantially wedge-shaped end walls 16, 18 interconnect the surfaces 8, 10 along the side edges of the surfaces.
• a connecting web 20 joins the base portion 14 of the protrusion 6 to the end 3 of the neck portion 4 , the connecting web being of lesser thickness than the protrusion base portion, to provide recess means 22 between the end 3 of the neck portion 4 and the protrusion base portion 14.
• the protrusion 6 is in substantial alignment with the neck portion 4, extending outwardly at an angle to the grip portion 2.
• the neck portion 4 is defined in part by front and rear walls 30, 32, preferably forming continuations, respectively, of front and rear walls of the grip portion.
• the first major planar surface 8 and the second major planar surface 10 are at an angle to each other, such that at the free end 12 of the protrusion, the surfaces are closest together (preferably about .043 in. ) and at the base portion 14 of the protrusion the surfaces are farthest apart (preferably about .093 in.).
• the protrusion is preferably about .25 in. in length 1 and .42 in. in width w.
• the recess means 22 preferably comprises two recesses 34, 36 defined in part by the web, which is about .066 in. in thickness t.
• a bore In the neck portion 4 there is provided a bore
• the plunger 42 may comprise a unitary molding including an attachment leg 52 having a detent 54 thereon slidably disposed in a recess 56 in the bore 40, and a trunk portion 58 movable in the bore 40, the leg and trunk portions 52, 58 being joined at a common base portion 60.
• the push button 46 To remove a shaving unit s from the handle, an operator presses the push button 46, causing the end surfaces 50 to push against an edge e of a housing portion h of the shaving unit s, forcing detents d, d' to override the base portion 14 of the protrusion 6.
• Plastic deformation of the shaving unit housing portion permits removal of the shaving unit and reuse of the handle with subsequent shaving units.
• the grip portion, neck portion, web and protrusion are molded or cast integrally as a unit, of plastic or of a more rigid material, such as metal.
• the protrusion 6 is introduced into a cavity c, defined by the housing portion h of the shaving unit s, the housing portion h having the inwardly directed opposed detents d, d'.
• the widest portion of the base portion 14, overrides the detents d, d', which snap into the recesses 34, 36 to lock the shaving unit s on the handle. Attachment of a new shaving unit forces the plunger 42 back to the position shown in FIG. 4.
