Description

Patented Aug. 22,` e i933 UNiTEDf-fsrgres e. AThis invention relates to arch-supporters vfor shoes, and Vmorelparticularly is an improvement over devices .illustrated vand described in my co-pending United States application for patent,

filedV February 26, 1929Serial No.. 342,869, for

which Letters Patent 1,844,017 issued Feb. 9, 1932. In such prior application, I have particularly illustrated and described in'detail the develop.-

` ment of a shoe conformed to present a transverse ridge peculiarly disposed inamanner such that the astragalus bone of a wearers foot is supported .without aieeting Veitheru'tlrie freedom ,of

lthe'vheelfbone, or the scaphoid and tarsal struc; ture constituting the instepl and toes.k A

The distinction is particularly set forth in lsuch construction of a support peculiar to the astragalus bone asv against .thel conventional archV supporters `heretofore utilized, suchlatter being conformed in a convex coniiguration'emigrating adjacent the metatarsal bones and. terminating in proximity of the rear of the heel. n

. Such/constructions alford but' temporary relief and culminatein .A an ossied condition of the 'bones due to the cramping of the Vbone structure of the foot. 7 f

The present invention, as with my prior .appli-k "cation, kis 'conceived to the end of allowingta Vfreedom of heel and tarsal bones by aifordingasubstantial rocker activity ofthe same-about an astragalus support. Recognition being taken of .the fact that the operation ofwalking consists in the successive-steps of initially coming down on thel heel and centralizing the weight ofthe body directly over the arch, with a subsequent release and av tread tothe ball of the footas thesucceeding step is taken, the primary objectof Athe "presentinvention over my prior'applicationis the `provision of an insertable arch supportembodying a: yielding heel rest in cushioning'the initial impact tothe ground. v A further object is the provision, in insertable arch supporters of the character described, 'of means for securely attaching the same to the upper of the shoe, in a mannerk such as to prevent shifting or creeping responsive to walking operations.

Witlithe foregoing and further objects and advantages in view, such as will become apparent throughout the course vof the following detailed description and claims, the invention consists in the novel constructionfadaptation and combination of parts hereinafter Vdescribed and claimed.

In the drawing,-

Figure 1 is an underneath 'plan indicating the preferred embodiment of the present invention.

Fig.` 2 is a longitudinal vertical section taken through a portion of 'a shoe,v the present invention, indicated inside.elevationjbeing applied therein, said view exemplifying by ldash liiiesth'eV contour of the ankle and footl indicating the bone formation thereof as applied to the shoe and arch supporter.

Fig. 3 is a transverse vertical section taken to ya rreduced scale of the arch supporter removed,y saidsection takenonline 3-.-,3 of Fig..Y 1, with thev exceptionthat the lattachment,stripV of the saine A `Reference being had'vtoliig. 2, representing therein the bone-contour of a human foot,Y the tarsal or instep structure. e, j ,y

VMore particularly referring thereto,` the os'calcis vor heel bone is normally disposed atan elevation below thatrofthescaphoid 8, being spaced therefrom at its'innerl side to provideia lrecess 10 within which the fleshy part of .the underfoot Y extends, said recess progressively increasing from the outer edge-` of the foot.

According tothe present invention, lIplrovide an insertable insole member, such as generally represented by '11,,-the bearing portion thereof on the. sole 12 of the shoeproper' being stamped from a single piecev of leather or other suitable material and pressed toprovide 'a plane faced heel `13.jogged upwardly at its forward end; and affording a Wall 15 disposed at an angularity of I approximately thirty degrees from the vertical.

Said wall, moreover, terminatesfin a shoulder or ridge portion 16 extending transversely ofthe insert, gradually diminishing from the inner 'to a point ademt @einer Side, wherea 'ne sami@ merges yto thev approximate upper plane vof the projection upwardly to the astragalus and tibia bones, a fulcrum affording rocker activity-and .11

extreme' flexibility to the os calcis and the tarsal structure of the bone.

, Said particularV and advantageous configura? tion of theinsert is suitably retained through heel. Said ridge, having a relatively lsmall radius," `is comparatively sharp, and constitutes inits the medium of a metal brace 17 rigidly'secured, 1

as byV shoe nails, to the underneathface and suitably conformed such as to have lits upper tive proximity to the ridge, the fore portion .V19

of insole 11 being beveled therebeyond to merge .be cemented to the face of heel portion 13 and the strip 22.

Projecting laterally from `said portion 19,*1 further provide a wing 24 disposed such as to accommodate a turn-up of the saine within the instep of the shoe upper, said wing being adapted to be sewed thereto about its horizontal and vertical edges in the preventionr of shifting 6rY creeping. Y Y

, The construction is believed evident from the foregoing. While I'have lhereindescribed and illustrated the preferred'embodiment, it is to be noted however, thatfI do not particularly confine-myself thereto except as by the scope of the rhereto annexed claims.

What I claim, is,- l. Inaril insertable insole for a shoe formed Ato provide in its rear portion Sa substantially plane face Aadapted to be disposed in the heel portion of the shoeythe front wall of said `heel portion extending substantially verticallyv up- Wardlyk to a transverse ridge from which the fore portion projects forwardly to the ball of the shoe, -the apex ofl said ridge forming arelativelyisharp angleserving to wedge into the lieshy part of the underfoot below the astragalus bone, said ridge Asloping downwardly from the .inner to the outer edge to merge atv the latter with the approximate plane ofsaid rear portion, a sponge cushion superposed over vsaid rear portion to act as a rest for lthe heelof the foot, said cushion tapering from av plane relativelyY in alignnrient with the inner'edge of the ridge to .a Vfeather edge on its outer side.

' '2. Ina device as defined in cla-im 1, wherein the frontv wall, transverse ridge, and'forward Aplatform vof said insertable vinsole `are retained by a metal brace secured to the underf-acethere- Yof and approximating the contour of the same.

3. In apparatus as dened in'Y claim l, wherein said insole'is conformed to present a wing projecting laterally of the forward platform, said Wing being adapted to a'turn-up within the' instep portion of the shoe upper for securing said Wing to the saine.V Y, Q

4. In an insole forv a shoe formed to provide a plane surface in its rear portion seating within the heel cavity lof the shoe, said heel surface being turned up at its `forward extremity to form a relatively sharp transverse ridge, progressing therefrom as a platformv beneath the instep of -a wearers foot, said ridge sloping downwardly from the inner to the outer edge and adapted to rear portion a cushion for the heel of the wearers foot, and at the fore extremity of said cushion, a transverse ridge having a relatively sharp apex arranged to wedge within the fleshy part of theY foot below the astragalus bone, said cushion and ridge sloping 'downwardly from the inner to the Vouter side ofthe shoe:

6. In an insertable arch supporter for a shoe, said supporter beingconforrned to present a ridge projecting upwardly to have the-Aapexthereof in substantial vertical alignment with a centerline taken through :the tibia andA a'stragalus bones` of a wearers foot, `saidsupporter projecting forwardly from saidA ridge '-,as a platform adapted to support the instep portion of the wearers v foot, arilexiblevving extending Vlaterally of said platform and adapted to berturned "up and vsecured alongsidetheinterior ofv the'shoe upper in preventing shifting of saidl supporter within the shoe. ,Y j

7. In an insertable arch supporter for a shoe, said supporter being'conformed to present aridge projecting upwardlyto' have Vthe apex thereof in substantial vert'ical'alignment with a centerline taken through the tibia and astr'agalusf'bones of a wearers foot, `saidV supporter projectingY forwardly from said ridge as a `platform,adapted to its supportjthe instep portion ofthe wearers -foot,

means for V,securing said supporterA to the shoe to prevent shifting of thesarne therein.

8. In an insertable 'arch supporter for a shoe, 'said supporter formed' to provide a transverse ridge disposed belowthe'astraga'lus bone of a' wearers foot, a'flexi'ble wing extending laterally of said supporter and adapted to be turned up for securernent alongside thev interior of the -shoe upper to prevent shifting of said supporter within the shoe.

9. In an 'insertable arch supporter for a shoe including a heel cushion,'said supporter formed to provide an abutment to the heel bone of a wearers footf'orwardly of the heel portion of, the shoeto prevent creeping of said heel conectowards the fore portion ofthe shoe, means 'cornprising a iiexible wing extending laterally of said irsV supporter :and adapted for securernent with the shoe toeprevent shifting of the supporter in the shoe.
