Definitions
- This invention relates to wet-shave type razors and is directed more particularly to a razor in which the blade assembly portion thereof is adapted for movement during a shaving operation to conform to the surface being shaved.
- Description of the Prior Art It is known in the art that shaving efficiency of a safety razor assembly may be improved if the blade assembly is adapted to pivot on the razor handle during a shaving operation, permitting the blade assembly to more closely follow the contours of a surface being shaved.
- Carbonell, et al are illustrative of razor handles adapted to accept blade assemblies in such a manner as to permit pivotal movement of the blade assembly during a shaving operation.
- U.S. Patent No. 3,950,849, issued April 20, 1976, in the name of Roger L. Perry illustrates a blade assembly adapted for pivotal movement.
- Patent No. 4,083,104 issued April 11, 1978, in the name of Warren I. Nissen, illustrate, respectively, a blade assembly and razor handle comprising a shaving system in which the blade assembly pivots on the handle during shaving.
- the pivoting action takes place about a given axis, limiting the accommodation which the blade assembly may make to the surface being shaved.
- a feature of the present invention is the provision of a razor assembly of the wet-shave type comprising a razor handle, a head portion extending from the razor handle, the head portion having therein a cavity with a hemispherically shaped bottom portion, spring retention means disposed in the razor handle, and spring means, the spring means comprising a foot portion retained by the spring retention means, a stem portion connected at a first end to the foot portion, the stem portion extending from the foot portion toward the head portion, a flange portion fixed to a second end of the stem portion and shaped com- plementarily to the cavity bottom portion, and connector means on the flange portion for connecting the flange portion of the spring means to a blade assembly, the spring means being adapted to facilitate pivotal movement of the blade assembly during a shaving opera ⁇ tion and being operative to urge the blade assembly to a neutral position in the razor head cavity.
- FIG. 1 is an elevational view of one form of razor illustrative of an embodiment of the invention, with one of the handle housing portions removed to view the interior components of the razor;
- FIG. 2 is a side sectional view of the razor
- FIG. 3 is similar to FIG. 2, but shows the components in exploded fashion
- FIG. 4 is a top plan view of the razor. DESCRIPTION OF THE PREFERRED EMBODIMENT
- the illustrative razor assembly includes a razor handle 2 , a blade assembly 4, and a spring member 6.
- the spring member 6 is anchored at a first end 8 and connected to the blade assembly 4 at a second end 10 thereof.
- the razor handle 2 includes a head portion 12 having a cavity 14 therein.
- the cavity 14 is defined by a floor wall 14a and upstanding walls 14b.
- the spring member 6 includes a rounded flange portion 16 at the second end 10 thereof, the flange portion 16 being provided with blade assembly connector means 18 (Figs. 2 and 3) , which may be detents, operative to engage and retain the blade assembly 4 (Fig. 2), as will be further described hereinbelow.
- the cavity 14 is provided with a rounded or hemispherically-shaped bottom portion 20 and the flange portion 16 has a complementarily shaped surface 22 (Fig. 1) .
- the spring member 6 includes a foot portion 24 at the first end 8 of the spring member.
- the foot portion 24 extends transversely of a stem portion 26 which interconnects the foot portion 24 and the flange portion 16 of the spring member.
- the foot portion 24 of the spring member 6 is anchored in the razor handle 2, as will be further described hereinbelow.
- the foot portion 24 may comprise a leaf spring, as illustrated in the drawings, connected at a central point to the stem portion 26 of the spring member.
- the handle 2 preferably comprises first and second formed portions 28, 30 (Fig. 3) connected together with the spring member 6 therebetween to form the razor handle (Fig. 2) .
- Each of the formed portions 28, 30 is provided with walls 32, 32a molded integrally therewith which, upon joining of the two formed portions with the spring member therebetween, adjoin to form a chamber 34 (Figs. 1 and 2) which substantially encloses the foot portion 24 of the spring member 6 to serve as a spring retention means and anchor the spring member in the handle.
- the chamber 34 is provided with an opening 36 through which extends the stem portion 26 of the spring member 6.
- the single widthwise wall 32 may be disposed between the foot portion 24 and the head portion 12 and serve as a spring retention means.
- the two formed portions 28, 30 are also provided with walls 38 which adjoin to form a compart ⁇ ment 40 (Fig. 1) which extends from around the opening 36 to an underside of the bottom portion 20 of the cavity 14.
- the spring means stem portion 26 is disposed in the compartment 40.
- the entire spring member 6, including the foot portion 24, the stem portion 26, the rounded flange portion 16, and the blade assembly connector means 18, is a single, unitary, molded plastic member.
- the two handle formed portions 28, 30 are of molded plastic with the aforementioned walls 32, 38 being molded integrally therewith.
- each blade of the blade means is independently movable during a shaving operation. The manner in which the blades are mounted for individual and independent movement is fully described in U.S.
- the blade means 52 comprises a first set of two blades 58 and a second set of two blades 60, the first and second sets of blades 58,60 having their cutting edges extending in opposite directions and toward the guard means 54.
- the blade assembly body portion 50 is provided with a ball means 62 having a rounded undersurface 64 shaped complementarily to the handle bottom portion 20.
- the ball means 62 includes opposed first and second ball portions 66,68 defining therebetween a slot 70, the slot 70 being adapted to lockingly receive the spring flange portion 16.
- the flange portion 16 is provided with detents 72 on either side thereof for engagement with the first and second ball portions 66,68 (Fig. 2).
- the flange portion 16 preferably is U-shaped, as shown in Fig. 2 , to provide springiness which will allow the detents 18 to pass through the slot 70 and engage the ball portions 66,68 during assembly.
- the above-described razor assembly is such as to allow the blade assembly to pivot about a multiplicity of axes, the ball means 62 being slidably movable on the handle surface 22.
- the combination of ball means and spring member permit dynamic movement of the blade assembly in response to pressures encountered in traversing a surface being shaved.
- detents 74 which serve as stop means to limit the pivoting movement of the blade assembly. Engagement between a stop means detent 74 and the razor handle cavity floor wall 14a (Fig. 1) serves as a positive stop to prevent further pivoting movement in that direction.
- the detents 74 prevent either end of the bade assembly from receding into the razor handle head too far. In pivoting about a blade assembly lengthwise axis, pivotal movement is limited by the engagement of blade assembly side walls
- the spring member continuously urges the blade assembly into a "neutral" position in the razor head, but permits movement from the neutral position in response to the surface being shaved.
- the present invention is by no means limited to the particular construction herein described and shown in the drawings, but also comprises any modifications or equivalents within the scope of the claims.
- the blade assembly may be of any selected construction including various arrangements of linear blade edges, as disclosed herein, but also arrangements of disk-shaped blades, as disclosed in U.S. Patent No. 4,807,360, issued February 28, 1989 in the name of Jeffrey C. Cerier, et al, and foil-type blades, as disclosed in U.S. Patent No. 4,483,068, issued November 20, 1984, in the name of Glynne E. Clifford.
