4. Claims.
This invention relates yto shoes and more particularly to a shoe having a substantially rigid arcuate support and. ground engaging member.
Objects of my invention are to provide a. device materially to reduce the fatigue fof walking; to provide a means vfor more evenly distributing the supported weight between the heel' and the ball of the foot while, walking; to relieve foot arch strain; 'to impart the rolling action of a wheel to walking; tojprovide a means for bringing ease andjnaturfalism to walking on an .articial leg; and to provide improved elements and arrangements thereof in a shoe ofthe 'character and for the purposes set forth.
In accomplishing these and other objects o f the present invention, I have provided improved details of structure, the preferred forms of which are illustrated in the vaccompanying drawing, wherein:
Fig. 1 is a longitudinal vertical sectional view of a shoe embodying the features of the pres-` ent invention.
p Fig. 2 is a side'ele'vational view of Va modified form of'a device embodying the features of the present invention adapted to embrace a variety of shoes to adapt the `advantages of this invention to shoes of conventional jdsign.
Referring more in detail tolthe draw-ing:
I designates ari-arcuate base member ofa size and material to provide a'vsubstantialiy inflexf ible rocker foundation for the shoe.
-A point 2 on ythe base `l`member I 'contiguous to the ball oflthe wearer'slfoot, -is` vthe 4point 'of the tangential joiningof- `two portions of the base member having diier'ent radii ofcurvature. During the normal'movem'e'nts ofwalking, the leg is pivoted respectively at the hip and yat the knee. When pivoting the leg -from the hip, the weight of the wearer is -borneby the base member I between point 2 and `the rear endof the loasemembeny When'tlle` knee becomes the pivoting point, vthe weight is shifted Aforward of point 2, The radius of curvature of a wheel always beingthe dis-tance from '-the`pivot point, the axle, to the peripheryof the wheel, the base member I isu-vformed to haveia fore and aft radius of curvature lfrom the 'pointzfrearward approximating the length of: the -wearers leg and a radius of curvature forward of the vpoint 2 ap-v proximating the vdistance between `.the weareris knee and the ball offhis -foot' to impart the roll ing action of a wheel towalking.
A ground engaging member 3 is preferably provided of suitable materialomthe 'lower side of the -base Vmember `I ato protect the base membel' from Weer 111,14' 119 @F517 31S 3 Suitable f-Qa: portion for theshoe.
A lift 4, or wedge, is secured to the upper urface of the rearward of the base mem- Fastened to. they base member I, a short distance rearward of point 2.; is a shank 5 vof substantially rigid construction held :in spaced rela.- tion to the base member at its rearward'endf by being `connectedto .and overlying .the upper portion vof the lift ,4.` The shank .5 .preferably formed of metal serves :as an arch support in the shoe. VI-Iowever, the primaryarch supporting `fea-ture `of this device is in the fact .that
the weight is transferred from the heel .of the foot to the ball of the foot by the curved .surface of the base member, thus relieving .the arch of strain.
For the wearers comtort. an inner sole (i is Secured by a suitableadhesive lmeans to the upwardly exposed surface of the base memberand shank 5,.

The sides 9 and-thetoe I0 of the upper yportionA 0f `the shoe extend .downwardly to fasten.
to the base mem-ber I.
A lacing flap -Il -andgtongue .portion I2 arei provided. e
The back Stay '1, the counter 8, the sides '9, the toe I mthelacing flap II and the `tongue por tion :I2 comprise la substantially conventional conventional manner ,of inserting the foot intov the foot receiving and positioning.means andlac-` iing .the vflaps I I,
In walking, `the rearward portionof the ground engaging member 3 is lrst to b ear 'the weight of the wearer. Instlgidingthe rst .partei Q.the
step is .usually made with .the legs straight; .all of the lpivoting of the leg `taking 1place Fat the hip.` The portion of the 4base lmember VI from point -2 rearwardhaving Va'g-radius of .curvature approximating the .length -Qf the :wear-@fs leg.
provides a .Convenient stelling, ;.Surface duringinth@ rStr-part of theater. {I'henortlon .of the' bete 3 member I rearward of the point 2 functions as the periphery of a wheel; the wearers leg, as a spoke of a wheel; and his hip, as a pivot point efrlcaciously to impart the rolling action of a wheel to walking.
As a stride progresses, the weight of the wearer of the shoe moves progressively forward on the foot. At approximately the time the weight reaches the ball of the foot the knee of the wearer starts to bend. During the completion of the stride the knee, not the hip, is the pivot point. This fact is advantageously utilized in the embodiment of this invention.
From point 2 forward, the base member I has a radius of curvature approximating the distance from the wearers knee to the ball of his.
foot. Similarly to the rst part of the stride its completion is accomplished by the portion of the base member I, forward of point 2, acting as the periphery of a wheel; the wearers leg and foot from his knee downward, as a spoke of a wheel; and his knee as a pivot point.
Mdijcation In Fig. 3, a modification of this invention is .provided to the end of making the advantages incident to the use of this shoe more generally available.
In this form of the invention a base member I3 of substantially inflexible material is provided.
A point I4 in the base member I3 is in subposed relation to the ball of the wearers foot and is the point of the tangential joining of two portions of the base member having dilerent radii of curvature.
From the point I4 rearward to the end of the base member I3, the radius of curvature of the said basevmember approximates the length of the wearers leg, as does the portion of the base member I rearward of the point 2 in Fig, 1.
The portion of the base member forward of the point I4 has a radius of curvature approximating the distance from the wearers knee to the ball of his foot, similarly to the radius of curvature of the base member forward of point 2 in Fig. 1.
A gr-ound engaging member I5fis fastened in conformity to the curvature of the downwardly disposed surface of the base member I3 preferably by suitable adhesive means.
lA transverse rib I6 is provided to engage in a bracing relationship the shoe on which the device is mounted to assist in positioning and maintain- `ing the device on the shoe in proper position.
A heel receiving portion I1 supports the heel of the shoe at a height and angle in keeping with the wearers predetermined comfort and convenience.
A plurality of openings I8 in the heel receiving portion I1 and the base member M, with counter sinking holes in the ground engaging member I5, comprise receptacles employed for the purpose of mounting the device on the shoe by means of screws of a length securely to engage the sole and heel of the shoe but of insucient length to pass through the said sole and heel.
In addition, adhesive means preferably are ernployed on the upper surfaces of the base member I3 and the heel receiving portion I1 to assist in fastening the device to the shoe.
So mounted, the device is used as described.
It is apparent therefore, that I have provided an improved shoe that materially reduces walking fatigue, that more evenly distributes the supandere 4 ported weight of the wearer between his heel and the ball of his foot while walking, and imparts the rolling action of a wheel to walking.
The embodiment of this invention is particularly well suited to use on an artificial leg. The rearward and forward rolling surfaces of the shoe provide an ease and naturalism to walking by means of an artificial leg heretofore not available.
It is further apparent that by striking the extreme forward portion of this Walking aid as an arc of a radiushaving a length extending from the ankle to the toe of the foot, this aid may also be employed to enhance the comfort of the wearer in dancing and other activities requiring bearing the wearers weight on the toes.
The chief advantage in this device is the transfer of the wearers weight from the heel to the ball of the foot through the aid rather than through the arch, thus alleviating possible strain on the wearers foot.
While I have shown but certain embodiments of my invention, it is susceptible to further modi cation without departing from the spirit of the invention. I do not wish, therefore, to be limited by the disclosures set forth, but only by the scope of the appended claims.
The invention described herein may be manufactured and used by or for the Government of the United States of America for governmental purposes without the payment of any royalties thereon or therefor.
I claim:
