BACKGROUND OF THE INVENTION
Field of th~ Invention . -- .
The invention relates to wet shaving implements and is - '~ directed more particularly to a razor blade assembly including 5 ¦I cap, blade and guard elements-connected together and replaceable ¦l as a unit on a cooperating razor handle.
Description of the Prior Art ...... __ . _ _ It is generally known in the art to provide a razor blaae '¦ assembly, which may be connected to, and used in conjunction with , ~li a razor handle to facilitate shaving operations. U. S. Patent ¦ No. 3,660,893, issued ~ay 9, 1972, shows a blade assembly in ¦ which blade means are held at either end thereof and disposed ¦ between blade assembly sur~aces adapted to engage the surface Il being shaved in front of and behind, xespectively, the blade ll means cutting edge portions. Such surfaces are generally re-ferred 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 movement of ¦I the blade means during a shaving operation. In addition, the I¦ guard and cap means are mounted for similar movement.

~l !1 13L30~7 11 , An object of the present invention is to provide a blade Il assembly, generally similar to the blade assembly disclosed ih - ~¦ U. S. Patent No. 4,168,571, but improved thereuver.
~¦ With the above and other objectsin view, as will herein-i after appear a feature of the present invention is the provision j of a razor blade assembly comprisin~ a body ~ember, a guard member mounted on the body member for movement thereon, blade means mounted on the body member for movement thereon, the ,, guard member and blade means being independently moveable in response to forces encounterea during a shaving operationr and spring f inger biasing means integral with the body member and Il exercising a bias against the guard member and blade means.
~1 1 The above and other features of the invention, including ~,l various novel details of construction and combinations of I 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 sho~n by way of illustration only l and not as a limitation of the invention.

! DESCRIPTION OF THE PREFERRED EMBODIMENT
¦¦ Referring to the drawings, it will be seen that the 15 Ij 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. E'rame portions 12 extend width-wise of the body member, interconnecting the front and I back walls 8, 10.
20 1l The back wail portion 10 of the body member 2 has an upper l portion 14 which engages skin being shaved behind the cutting ¦¦ means of the assembly, thereby fulfilling the functions and ji occupying the position of the "cap" portion of conventional l razor blade assemblies. Such portion 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 disposed transversely to the frame portions 12. Onc il of the ~rame members 12 near the first end portion 4 is pro-?! vided with spring fingers 1~ extending therefrom generally `
parallel to the front and bacX walls 8, 10. Each of the finger~
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 ~ I -! 18~ of similar configuration, with upturned en~ portions 20i ?
! having upper surfaces 22'. The fingers 18, 18' extend in Il opposite directions, the fingers 18 extending toward the first ij end portion 4 of the body member 2 and the fingers 18' extending I toward the secona end portion 6 of the body member. The fingers - jl 18 and the fingers 18' are aligned with each other and with the ?l slots 16.
¦ ~he assembly includes a guard portion 24 having a slide member 26 at either end thereof. The slide members 26 are received in a pair of opposed slots 16 nearest the front wall ~¦ portion 8. The bottom of the guard portion rests upon the ¦ surfaces 22, 22l of the spring fingers 18, 18'. The lower ¦ edges 28 of the slide members 26 rest above the bottoms of I their slots 16, allowing the guard portion 24 to be moved furthe~
into the slots, against the bias of the spring fingers there-Il beneath. The spring fingers supporting the guard portion com-¦ prise a set of spring fingers, the object of which is to ?I resiliently support the guard portion. In shaving operation, !¦ the guard portion travels over the surface being shaved ahead I¦ of the cutting ~eans.
