Patented Nov. 27, 1951 UNITED" STATES PATENT OFFICE 2,576,247 f i f REMEDIAL FOOT, sorrow Albert Woodthorpe, Toronto, Ontario, canaaa Application February 1, 1951, SerialNo. 208,861
This" invention relates to improvements in remedial foot supports, and more: particularly to supports of the type disclosed in United states Patent No. 1,928,634 which was issued to Sterling Le Roy Spider and Harold Stewart Bovaird on October 3, 1933. r
In supports for the relief of arch troubles and kindred ailments it is common to provide pads or artificial elevations which exert direct pressure upward and into the foot tissues. These pads or elevations tend to become rigid as the body weight bears down upon them, and unyielding pressures are created which do not encourage normal re-alignment of the muscles and ligaments of the foot.
According to this" invention, these disadvantages may be overcome by providing an essentially flat and smooth surface for the foot to rest upon. This surface is constructed of resilient material, and is supported by a resilient mechanism in such a way that the surface readily accommodates itself to the actual needs of theindividual foot, providing free and natural muscular, ligamentary and osseous action, and specificany avoiding all direct pressure by localized parts. Since the requirements of different feet vary, this invention permits the body weight to determine how much support is needed, rather than giving arbitrary support in definite areas only. Foot balance is improved, normal circulation of the blood is encouraged, the ligaments of the feet are properly re-adjusted, permanent correction and strengthening of the foot tissues is encouraged, and more enduring. comfort and improved posture in walking and standing is achieved. Relief is afforded to the feet, legs, hips and spine.
In this invention, resilient support is provided in special places which are not supported in any of the conventional archsupports. In' its action the support also massages the foot during It is the object of this invention to achieve the aforementioned results in a remedial foot support which is of simple construction, easily produced, fitted and adjusted, of light weight andwell insulated and ventilated.
Other objects and advantages of the invention will be apparent from the following description.
In the drawings which illustrate one embodiment ofthe invention, and in which like reference numbers indicate corresponding parts in the several views:
Fig. 1 is a perspective view of the bottom of a remedial foot support for the left foot;
Fig. 2 is a bottom plan view of the support;
Fig. 3- is aside view showing the support placed in the shoe and supporting a foot. Part of the shoe is; cut away to show the arch support;
Fig. 4 is a sectional view taken along line 4-4 inFig. 2; and
Fig.- 5 is=a sectional view taken along line 5 -5 inniaz. Fig; 3 shows a left foot! fitting into a shoe which has the usualupper 2 and sole 3; The" foot rests upon an archsupport constructed in accoruahee with this invention.
In the arch support illustrated, a mainplate 1, made of a resilient-metal such as finely spun Swedish steel, is preferably formed with sub stanti'ally parallel edges, the rear end. being" rounded and the front end suitably truncated. The mainplate is slightly arched from end to end. Asshown Fig.3, the arch supportis so" positioned in the shoe that the front end of the mainplate lies just tethe' rear of the ball of the foot. j
Attached above m'ainplate I by rivets 5 is a pressed cork compound or similar soft resilient material. Pad 6 isthe same shape asmainplate 1, exce t that thep'ad is somewhat wider adj acent the instep of the'ioot.
1 secured abo e pad" may rivets 5* is a foot piece 4' which is cut s'o'thdt its ohtour conforms generally with'rhat of the inside Ofthe' shoe."
Foot piece fl-has a forward fiap' which projects under the Ball of the foot, beyond pad 6 and main late 1', the has being skived' thin in orderto avoid impression upon the foot. The rear edge of footpiece 4 is trimmed to fit against the heel As shown in- 5-,- the front and rear ends of.
tongue 9 are flat, but the tongue slightly arched between its ends. The tongue serves as a resilientclamping member which firmly holds resilient pads ['0 H and [2 between the tongue and the-mainplate. V Normally, there'silient pads will be clamped above T-head '9' and bars 9 and 9 respectively; but they may be shifted in position to meet the requirements" of the iiidividual' foot. Pad flyover-har 9 near the heat, provides resiliency at a place which: has been neglected inother foot correctivedevices, and
furnishes additional comfort and correctiveaction andiI-nproves thebalance of thewearer.
Making T-head1 9 flat, asshown Fig. 5t causes the. tongue to bend. toward the mainplate at its front end to hold pad [0 securely in poe ,sition. The edges of ahead-,9 arelcurveclupgl.
In the preferred embodiment,
It is thought that the construction and the use of the invention will be apparent from the above description of the various parts and their purpose. It should be understood that the form of the inventionherewith shown and described is to be taken as'a preferred example of the same and that various changes in the shape,
"l'fisize and arrangements of parts may be resorted only slightly and operate almost independently a to provide resilient action over the whole of'the support. Being light and resilient, thetongue is free to twist and to bend transversely as well as longitudinally and thusto'respond to'the" constant shifting of weight from point togpointi which occurs during wallging.
It is to be; understood that the tongue 9 may be E- or F'-shaped with a longitudinal stem'providinga resilientbase along the longitudinal arch oi the fobtQand bars extending out from the stem across the bottom of the foot. Any of these constructions encourage normal weight distribution upon the metatarsal heads and the heel, rather than lifting or supporting directly any sagging tissue, and thus avoid any crutch-like action which prevents the normal re-alignment of muscles and ligaments. Because of the resilient action which encouragesnature, the wearing of this support isnot habit-forming. The support is not weakening, butf'rather strengthens the foot tissues by encouraging their'free action in a correct manner.
It is thought that it will be clear from the above description that the one-piece, longitudinal tongue 9, is an improvement overthe longitudinal and transverse spring strips in Patent No. 1,928,634. The present construction elimihates the awkward transverse'spring strip, which was open at one side only, and, being riveted to one edge of the mainplate, tended to weaken the mainplate and to decrease its resiliency. The special rivets of the "transversespring strip interferred with the smooth surface" of the mainplate, and these have. likewise been eliminated. The improved support 'h'as'greater versatility since the resilie'ntpads' I0, I [and [2 can be positioned and adjusted to meet individual needs. H
The improved design of tongue 9 and the use of the resilient pad H below the instep have done away with the need for a metallic lip on plate 1 to support'pad '6 beneath the waist of the foot. Similarly, the metatarsal pad, attached to the mainplate in Patent No. 1,928,634, can be eliminated. Any rigid or irritating points above the mainplate are thus avoided.
The felt pad in Patent'No. 1,928,634 has been replaced by a special pad 60f compressed cork and paper, or'the'like'which is non-absorptive," of reduced bulk, serves as an excellent heat insu'-' out to conform with the heel portion of the shoe,
so that the individual foot'is supported in exactly the right position. With the foot so positioned, the arch support doesnot move in the shoe. Body weight near the front of the support prevents longitudinal forward movements and the heel portion of the shoe prevents movement rearwardly. Because of this, the rearward projection; of the longitudinal metallic: stripin Patent 1,928,634 can be eliminated. -w-
