Abstract

The field of the invention is razor blade assemblies. Shown is an assembly including a body member (2), a guard member (24) fixed to the body member for movement thereon, blade members (36), (36') mounted on the body member for movement thereon, spring finger biasing means (18), (18') integral with the body member and exercising a bias against the blade member, and a cap portion (14). Due to the spring biasing the blades may move within their slots (16) to provide a dynamic adjustment.

Description

A RAZOR BLADE ASSEMBLY BACKGROUND OF THE INVENTION Field of the Invention The invention relates to wet shaving" implements and is directed more particularly to a razor blade assembly including cap, blade and guard elements connected together and replaceable as a unit on a cooperating razor handle. Description of the Prior Art It is generally known in the art to provide a razor blade assembly, which may be connected to, and used in conjunction with, a razor handle to facilitate shaving operations. U.S. Patent No. 3,660,893, issued May 9, 1972, shows a blade assembly in which blade means are held at either end thereof and disposed between blade assembly surfaces adapted to engage the surface being shaved in front of and behind, respectively, the blade means cutting edge portions. Such surfaces are generally referred to as "guard" and "cap". U.S. Patent No. 4,084,316, issued April 18, 1978, discloses a similar blade assembly, but one in which the blade means are supported by thin strips of metal. In U.S. Patent No. 4,168,571, issued September 25, 1979, there is disclosed a blade assembly whose blade means are attached to thin metal strips which in turn are mounted for movement in the blade assembly to permit dynamic ove- ment of the blade means during a shaving operation. In addition, the guard and cap means are mounted for similar movement.
" TC.-.r SUMMARY OF THE INVENTION An object of the present invention is to provide a blade assembly, generally similar to the blade assembly disclosed in U.S. Patent No. 4,168,571, but improved thereover.
With the above and other objects in view, as will hereinafter appear, a feature of the present invention is the provision of a razor blade assembly comprising a body member, a guard member fixed to the body member, blade means mounted on the body member for movement thereon, the blade means being movable in response to forces encountered during a shaving operation, and spring finger biasing means integral with the body member and exercising a bias against the blade means. The above and other features of the invention, including various novel details of construction and combina¬ tions of parts, will now be more particularly described with reference to the accompanying drawings and pointed out in the claims. It will be understood that the particular blade assembly embodying the invention is shown by way of illustration only and not as a limitation of the invention. The principles and features of this invention may be employed in various and numerous embodiments without depart¬ ing from the scope of the invention. BRIEF DESCRIPTION OF THE DRAWINGS
Reference is made to the accompanying drawings in which is shown an illustrative embodimeht of the invention from which its novel features and advantages will be apparent. In the drawings:
Fig. 1 is a front elevational view of one form of blade assembly illustrative of an embodiment of the inven¬ tion?
Fig. 2 is a back elevational view thereof; Fig. 3 is a bottom plan view thereof;
Fig. 4 is a sectional view taken along line IV-IV of Fig. 2; and Fig. 5 is a perspective view thereof; shown with a razor handle adapted to be used in conjunction with the blade assembly.
DESCRIPTION OF THE PREFERRED EMBODIMENT Referring to the drawings, it will be seen that the illustrated razor blade assembly includes a body member 2 having first and second end portions 4, 6 interconnected by front and back wall portions 8, 10. Frame portions 12 (Figs. 2 and 3) extend width-wise of the body member, interconnecting the front and back walls 8, 10.
The back wall portion 10 of the body member 2 has an upper portion 14 which engages skin being shaved behind the cutting means of the assembly, thereby fulfill¬ ing the functions and occupying the position of the "cap" portion of conventional razor blade assemblies. Such por¬ tion 14 shall, for that reason, be referred to hereinafter as the "cap portion".
Each of the end portions 4, 6 is provided with opposed slots 16 (Fig. 4) . One of the frame members 12 near the first end portion 4 is provided "with spring fingers 18 extending therefrom generally parallel to the front and back walls 8, 10 (Fig. 3). Each of the fingers 18 is provided with an upturned end portion 20 having an upper surface 22. In like manner, another of the frame members 12 near the second end portion 6 is provided with spring fingers 18' of similar configuration (Fig. 3), with upturned end portions 20' having upper surfaces 22'. The fingers 18, 18* extend in opposite directions, the fingers 18. extending toward the first end portion 4 of the body member 2 and the fingers 18* extending toward the second end portion 6 of the body member. The fingers 18 and the fingers 18' are aligned with each other and with the slots 16.
The assembly includes a guard portion 24, which is an extension of the front wall portion 8, and which, in a shaving operation, travels over the surface being shaved ahead of the cutting means. The assembly further includes blade means com¬ prising first and second blades 36, 36' (Fig. 4) each comprising a shaped member having a base portion 60 resting upon a pair of the spring fingers 18, 18' and a cutter portion 62, the two portions 60, 62 defining therebetween an outside angle. In use, the blades 36, 36' are individually movable in the planes of the base portions 60, respectively, and are able to move in response to pressure applied thereto further into the slots 16, and to move upwardly in the slots 16 in res- " ponse to the bias of the spring fingers.
The first and second blades 36, 36' are clamped in place by spring clamps 40, which are received in slots 42 in the end portions 4, 6. The clamps 40 engage the blades 36, 36', forcing them into the slots 16 to a point where a slight stress is placed on the spring fingers 18, 18 ' .
The assembly is provided, on its underside, with connecting means 44 by which the blade assembly may be connected to a cooperating razor handle R, as illustrated in Fig. 5.
In use, the blade assembly is connected to the handle R and used for shaving operations, during which the blade means 36, 36', are individually movable in the directions in which extend the slots 16. Thus, the blade components of the blade assembly may adjust dynamically to the surfaces being shaved.
It is to be understood that the present inven¬ tion is by no means limited to the particular construction herein disclosed and/or shown in the drawings, but also comprises any modification or equivalents within the scope of the disclosure.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:
