United States Patent Q CUSHIONING SHAVING HEAD UNITS FOR SHAVING IMPLEMENTS Jacob L. Kleinman, A. Lackenbach, 40 Exchange- Place, New York, N.Y.
Filed Dec. 8, 1959, Ser. No. 858,088
7 Claims. (Cl. 30-43) This invention relates to the construction of shaving units in general, and more particularly to a type of shaving unit used in connection with electric razors or dry shavers.
A primary object of this invention is to provide an assembled shearing section comprising a carrier and an assembled shaving unit wherein such unit comprises a base portion and a hair cutting section having an outer cutter member and a reciprocatory cutter member and spring means and wherein such cutting section is carried by the'base portion and is movable with respect thereto for being yieldable or retractable to cushion the touch of its shear face upon the face being shaved.
For clarification purposes I wish to point out the following:
The present type of shaving units, used in connection with dry shavers or electric razors, are so constructed that when secured to the handle the shearing face of the outer cutter member of the unit becomes a rigid part of such handle; and when being moved over the face for shaving purposes such shearing face doesnot move gently thereover but is rather rubbing against the skin of such face being shaved, so that when pressed against the face during shaving operation the fine shearing teeth, or cutting edges of the outer cutter member scratch the skin of such face during such shaving operation; this is due to the fact that the shearing face of the outer cutter member is, as aforesaid, immovable and can not become automatically retracted for cushioning the touch thereof against the face during such shaving operation.
Whereas, in accordance with my invention, I produce an independently assembled shaving unitwherein the outer cutter member and the reciprocatory cutter member are both movable in amanner whereby their combined shearing faces are automatically reciprocatable, retractable or tiltable while being moved over the face being shaved; thus, when applied against the face for shaving. purposes, such shear-face will yield, or automatically draw backwardly, in a manner adjusting itself to the curvatures of the face being shaved; such shear-face will. therefore move gently over the face being shaved, co-- operating therewith under suitable spring-tension, thus. eliminating rubbing or scratching the usersfaceduring. shaving operation.
To illustrate theordinary commercial utility of my cushioning shaving head units in daily life, a cushioning unit made in accordance with my invention, of whatever style or type it may be made, could be utilized to great advantage; the fact that the outer cutter member of my shaving unit in cooperation with its cooperatingcutter member are both simultaneously movable or reciprocatabl'e within its position in a manner bringing its shearfaces into desirable locations, instant forward. and re! tractable or tiltable movements, enables such shear-faces to adjust itself upon the face being moved andto engage automatically the very curvatures thereof; they willautomatically adjust themselves with respect to every portion of the face being shaved, provide gentle contact therebetween and will also minimize breakage of thefine lustrated in the drawing in connection with a specific:
embodiment of the invention.
In the accompanying drawing in which such specific embodiment of my invention is illustrated, and described in the annexed specification, wherein the accomplishment of the above and other objects of the invention will be readily understood on reference to the herein, wherein:
Fig. 1 is an exploded view showing my cushioning shaving head unit with its parts in separated position;
Fig. 2 is a cross-sectional front view of my shaving unit in assembled form in normal shaving position;
Fig. 3 is a view similar to that shown in Fig. 2, showing the outer cutter member with its shear-face inre tracted position;
Fig. 4 is a cross-sectional view taken along the line 4-4 of Fig. 3, showing the inner structure of my shaving unit;
Fig. 5 is a top View of the carrier to which the units are secured for being positioned upon a seat of a handle for shaving purposes;
Fig. 6 is a fragmentary perspective view of a portion of the carrier shown in Fig. 5;
Fig. 7 is a view, partly in cross-section, showing the manner of attaching my shaving unit to the carrier and the removal of same; and
Fig. 8 is a view showing another form of structure of my cushioning shaving head unit.
I am showing the several figures or views by way of example for illustrative purposes and for a better and clearer understanding of my invention, and not for limitation purposes.
Referring more particularly to the drawing, in which similar reference characters identify similar parts in the several views, in the novel structure of my invention:
A indicates the outer cutter member, B indicates the movable or reciprocatory cutter member and C indicates a'carrier or base section or portion for supporting the outer cutter member.
For clarification purposes I wish to point out the following:
The ordinary type of shaving unit consists of two members; namely, outer cutter member having a co-operating reciprocatory cutter member; such shaving unit may be secured to a seat of a handle by having its outer cutter member fixed rigidly directly to such handle holding its shear-face in a non-movable position. Whereas, in my present invention, my shaving unit comprises three sections; namely, an outer cutter member, a movable or reciprocatory cutter member and a base section. in my present structure the outer cutter member is not secured directly to the handle section but is secured to the base section and such base section is then secured to the handle section; the outer cutter member is secured to the base section in a manner whereby such outer cutter member is movable in a transverse mechanical manner relative to such base section, in a manner whereby (as above pointed out) the shear-face of such'outer cutter member in conjunction with the shear face of its cooperating cutting member may perform instant smears p mechanical forward and retractable or tiltable movements transversely relative to the said base section C for automatic adjustment with respect to the face being shaved, thus engaging every partrof the skin during such shaving operation; a function which can not be accomplished with the ordinary -typeof shaving units.
The base section C may be madein any suitable manner or style, but it may be so constructed wherein it may comprise a floor portion 11 having openings 12 and 12' (Fig. l) and a shoulder portion 14 and flap-sections 15 and two upwardly extending wall portions 16 each terminating into a loop or flange portion 17, for a'pur pose which will be hereinafter explained; I
i The outer cutter member A comprises a shell d having a shear-face 21 and two downwardly extending wall sections 22. The bottom portion 24 of the'outer cutter member A is provided with two, loop sections 25 'for housing therein the lower endportions of the wall sections 22 as shown at 26, and is also provided with an elongatedly shaped opening 27 Such wall sections 22 are each provided with extending portions 28, shaped in any suitable or desirable manner; for example (as herein shown) being part of the wall portion 29.
The movable cutter member B comprises a shearface 31 having two downwardly extending wall portions 32, carrying therebetween elements 33 each having a screw-threaded opening 53. 7
My structure may be assembled in the following manner:
The shell d of the outer cutter member A is positioned upon the under section a" having each of the lower end portions of the wall sections 22 located within one of the loop sections 25 and secured thereto by suitable means, for example, friction fit, rivetingor welding process. The movable or reciprocatory cutter member B is then positioned within the outer cutter member A for example as shown in Figs. 2, 3, and 4, thus providing a combined shearing section having the shear- -faces 21 and 31 in frictional engagement with each other for shaving purposes.
A spring element 35, provided with elongated openings 36 and with a centrally located downwardly bent or recessed portion 37 carrying therein a screw-threaded member or nut 38 is secured to the bottom portion 24 of the outer cutter member A by suitable means, for example, rivets 41 (Fig. 4). Such downwardly bent portion 37 is provided with an opening 39 located in alignment with the screw-threaded opening 43. The outer cutter member A is then positioned in a suitable manner, for example, slidable movement within the spaced portion of the base section C having the extending portions 28 located directly under the loop or flange portions 17, having its shear-face 21 locatedabove the base section C. The screw-threaded member 42 is then positioned through the opening 12' of the floor portion 11 and then through the opening 39 of the bent or recessed portion 37 and then in a rotatable manner into the screw-threaded opening 43 of the member 38, thus securing the spring element 35 in desired position to the r floor portion 11 of the base section C; and, simultane ously therewith, holding the outer cutter 'member A secured in its position thereon for operable purposes.
The spring element 35 is provided with a plurality of end portions 45, and when assembled as above described, each of the end portions 45 will engage a portion of the floor 11 and urge the outer cutter member towards an upward position, transversely relative to the base section C, as shown in Fig. 2, the distance of such upward move ment will be checked or limited by the extending portions 28 engaging the under faces of the loop or flange portions 17 as shown at 46 (Fig. 2), holding the' combined assembled shaving unit in normal shaving position; however, during the shaving operation, while the instrument is pressed against the face being shaved, such outer cutter member will, under the strain of such pressure automatically retract and exert pressure upon the end portions 45 of the spring element 35 and cause instant mechanical backward and forward movements 'of the full length of the outer cutter or of either one of the end portions of such cutter member thereby adjusting itself into suitable positions for having its outer shearface 21 engaging the very curvatures of the face being shaved, co-acting or co-operating with each portion thereof, thus providing the user with a properly desired clean shave (see dotted lines 47, Figs. 3 and. 4).
An elongated element 51, having a screw-threaded end portion 52, positioned through one of the openings 12 of the base section C and through one of the openings 36 of the spring element 35 and through the slot or elongatedly shaped opening 27 of the bottom portion 24 of the under section d (which forms the under portion of the outer cutter member A) and then having its end portion 52 positioned in a rotatable manner within the screw-threaded opening 53 of the element 33 and secured therein in a tight frictional manner. In the present structure I am showing two of such elements 51 being utilized for the following reason:
The outer end portions of these elements 51 are each provided with a screw-threaded tubular opening 54 having a non-circular or hexagon shaped head section 55 each adapted to receive thereover one of the end portions 56 of a spring structure 1.
The end portions 56 of the spring structure 1 are each provided with an opening 57 (Figs. 1 and 4) located in alignment with the screw-threaded openings 54 of the element 51Vfor having a screw-member 58 positioned therethrough and placed within the screw-threaded opening 54 of the element 51 in a rotatable manner, and secured therein for holding the end portions 56 of the spring structure 1 in position upon the head portions 55, thus holding the spring structure 1 in a suspended position underneath the base section C. Each of the end portions 56 are provided with suitable means, for ex ample, wall portions 61, for engaging the hexagon shaped head sections 55 to prevent accidental rotation of the element 51.
Thus, as above explained, is the manner in which certain forms of structure of my cushioning shaving head unit may be assembled into a unitary structure.
My above described shaving unit may be positioned upon any suitable seat structure of a handle for being held thereon in a position for shaving purposes, however, for illustrative purposes, I am showing my shaving unit secured to a carrier or holder e; such carrier 2 comprises two spaced apart wall portions 62 carrying therebetween two elongatedly shaped portions 63, each of such portions 63 being located in a obliqued position with respect to the other, as shown at 64 (Figs. 5, 6 and 7).
The floor portion 11, of the base section C, is provided at each of its end portion with a shoulder section or portion 14 each carrying thereon a movable spring section S. This spring section S is provided with a circular shaped end portion S' terminating into a sidewardly projecting portion 65. The opposite end portion 'of such spring S is provided with a semicircular shaped form 66 terminating into an outwardly curved portion 67. This spring S is adapted to be turned or hinged upon the shoulder portions 11, so that when my assembled shaving unit is placed upon the carrier e each of the spring sections S may then be turned into desired position, having its curved portion 67 snapped into position engaging the under portion 68 (see section indicated by arrow L, Fig. 1, also 'Figs. 4 and 7) thus holding the shaving unit secured in its position upon the carrier e. Such spring section S may be provided with a somewhat bend portion, or the like, as indicated by numeral 71 (see section L, Fig. 1, also Fig. 7), for engaging the wall-face of the elongatedly shaped portion 63 to tighten or lock the spring engagement between the portions 66 and 68 as clearly shown bythe indicating arrow 69 (Fig. 7). Movingthe curvedportion 67 backwardly, asindicated'by the dotted-lines 74, will unlockthe spring sections from the carrier for the removal of the shaving unit from itsposition upon the carrier e.
If desired, the under face, 'or floor portion, 11 of the base section C may be provided with flap-sections 15 for being positioned between the two elongatedly shaped portions 63, for example, as indicated by arrow K, Fig. (also see Fig. 4), for the purpose of preventing longitudinal movements of the assembled unit upon its seat.
The sidewardly projecting portion 65, of the circular shaped end portion S, is yieldable to an extent whereby it facilitates the slidable movement thereof for placing the circular shaped end portion '8' into position upon the shoulder portion 14 foroperable purposes.
The above has been explained by way of example and not for limitation purposes. .For example, it is shown herein that the actuating member 75 is provided with a head portion'76 for engaging the recessed section 77 of the spring structure f-for tensioning same to operate or oscillate the movable or reciprocatory cutter member B within the outer cutter member A (Figs. 1 and 4); however, if desired, the elements 51 may be eliminated and the spring structure 1 may be secured directly to the elements 33 by means of-screw elements 58 or rivets 78 or other suitable means, and be flexed or tensionedby the pressure of the actuatingtmember 75 as indicatedby the dotted line 79 (Fig. 8). Orthe spring element 35 may be eliminated and twoseparate spring members. 81 may be utilized in its place; such springs 81 may be secured in desired positions by any suitable means, ,for example, rivets,82 orscrew members 83, or other suitable means. The bent or curved portions 84 of thespring members 81 orthat of 85 of the spring structure will take up or bend in avmanner allowing the flexing or tensioning'action of such springsfor urging thetmovable cutter member B into co-operation with the outer cutter member A for shaving purposes.
After the independently-assembled shaving unit has been secured to the carrier e such carrier may then be secured, inany desirable manner, to a properly shaped seat, of ahandle structure 88, for example, as shown by numeral 8.4 (Fig. 4). Such handle structure or seat not being a part of" this invention will therefore not be explained herein. As a matter of fact, if desired, the shaving assembled unit may be secured directly to the handle seat, thereby eliminating the carrier e. It is thus clear that various forms of structure may be resorted to within the spirit of the invention.
From the above it is evident, that my present invention teaches an entirely new form of structure in the art of making assembled shaving units for electrically operated shaving implements; a structure which is unique in its ability to reciprocatedly adjust itself to the portions of the face being shaved and to co-operate therewith for engaging every curvature thereof for clean shaving; and wherein such unit may be secured into position without the aid of screw-threaded elements; and although I have shown certain preferred forms or illustrations in order to explain and describe the novelty of my invention, yet, by showing such structure, I do not, by any means, limit myself to these structures, nor to the terms used in describing same, as they are for illustrative purposes only. Various suggestions and changes of structure may be resorted to. And although I have mentioned of what material certain parts may be made, how they may be formed, shaped or styled and how they may be assembled, yet, I desire it to be understood that this structure, or part thereof, may be made of any suitable material, and shaped, formed, styled or arranged in any desirable manner, and assembled in any convenient way so that the parts may be easily taken apart, removed, cleaned, replaced and reassembled, and that various changes in detail may be resorted to without departing from the spirit of this invention.
