SHOE AND FOOT SUPPORTING DEVICE Filed Oct. 8, 1931- INVENTOR.
Patented Sept. 11, 1934 UNITED. STATES PATENT OFFICE My invention relates to a shoe and foot-supporting device, and in particular to a means, adapted to be fitted into and incorporated as a part of a shoe suited for use by humans, whereby a snug fit with support about the ankles is provided. It relates to a piece of spring metal so designed, shaped and located in a shoe that the application of downward pressure, such as by the weight of the wearer when standing in said shoe causes the application .of a supporting pressure to the sides of the shoe adjacent and below the ankle.
One of the objects of my invention is to eliminate some of the foot-troubles commonly resulting from a lack of Support of feet adjacent the ankle. Another object is to provide a means whereby the supporting force is the greatest at the time it is most needed. namely when ones full weight is on the shoe and least when one is in repose and no weight is applied to the shoe. This variation in the application or intensity of the supporting force tends to cause an exercising of the foot muscles which is desirable in preventing arch trouble. My device may be made a part of an arch-support or rather may include an arch support as "a part thereof.
Figure 1 is a perspective elevation of one form of the spring-tension element adapted to be incorporated in a shoe.
Figure 2 is a sectional view of the same element shown in perspective in Figure 1.
Figure 3 shows in elevation a shoe having the spring element incorporated therein.
Figures 4, 5 and 6 are modified forms of the 5 spring-tension element.
The numbering system is identical in the various figures.
All of the figures illustrate my invention rather diagrammatically.
In Figure 1, the side wings I and 2 are continuous through the base plate 3 which is somewhat arched so that downward pressure on 3 causes an inward pressure on 1 and 2, that is, it causes the upper portions of them to tend to come together. The wings 1 and 2 may be formed according to the contour of ones foot and need not be shaped as shown in Figures 1 and 2. A fibrous cushion element 6 is usually located above the base plate 3- which may be fastened to said plate.
In Figure 3 the spring-tension element is shown in place in a shoe, the base plate being over the forward portion of the heel. That element may be so designed that the base plate is located at the ball of the foot or just to the rear thereof as in Figure 4 or it may be located elsewhere such as at the arch or at the middle or back portion of the heel.
In Figure 5 the wings I and 2 are connected at the rear end by 4 with which it is made 9 substantially continuous. In this modification the rear portions of the wings are subject to less movement by reason of spring tension exerted by the spring element 3 than the forward portionof said wings.
I find that with many individuals, using shoes without a snug support adjacent the ankles, there is a tendency for the foot to sag to one side or the other (right or left) and for-the arches to fall. I claim to alleviate these troubles by I0 the use of the properly shaped spring-tension element located in a form-fitting position in the shoe. 7,
One of the features that I believe to be new and novel in connection with a foot support I is the arched bottom or base plate shown at 3 in the various figures. This may be made of material having such a spring tension as to act or function as a cushion but in any case it is adapted to be the means for causing the wings O0 1 and 2 to cling to the foot giving it support when a downward pressure is applied to said plate such as when one walks or stands in shoes fitted with the spring-tension element. Adownthis in turn pushes the wings 1 and 2 further apart at the base but tends to bring them closer together at the top- This is a desirable feature. The amoimt of arching of base 3 may be that found to be most satisfactory for a particular no case. Base plate 3 may be corrugated as shown in Figure 6 or have other shape but it is desir able that theshape be such that -a downward pressure on said plate will cause an inward supporting pressure on the upper portion of wings 1 and 2 of the various figures.
The spring-tension element is adapted to be fitted into a shoe, preferably as a permanent part thereof; it is adapted to be sewed to the leather or other flexible portion of the shoe. Holes are 1 shown at 5 of the figures whereby the spring-tension element may be stitched to the shoe. Although the holes asshown are along the upper portion of the wings it is understood that they may be located elsewhere. In fact the element 5 may be made of metal having a portion so thin that it can be stitched to the shoe without any perforations being made prior to stitching. It preferably should be located in the 'shoe in such a manner that the base plate 3 is covered withv ward pressure applied to 3 tends to flatten 3 and 85 Q 7 a fibrous or elastic material such as leather or rubber. When incorporated in a shoe at the time said shoe is made the fibrous or elastic material need not be a part of the device but rather a part of the shoe in which the base plate is fitted;'
when the device is to be used in shoes not originally equipped with the device it is commonly desirable to have the cushion member fastened to the top of the base plate. The entire metal portion of the element may be covered with leather, and preferably is so covered when the element is intended for use as an adjunct to shoes not originally equipped therewith. Other material maybe substituted for the leather covering, for example, cloth or synthetic leather.
It is understood that the wings of the element may be connected at the back as shown in Figures 5 and 6. The wings normally and preferably are thinner at the top than at the portion near the base. Thus my device may be used chiefly for supporting thefoot or massaging the muscles,
. on the other when so desired; it iscommonly desirable to have the wing adjacent the wall of the shoe next to the inner side of the foot heavier,
or under greater spring tension, than the outer When the spring-tension element is in place in a shoe it reinforces the walls of the shoe adjacent but below the ankle and lends support to the ankle whenthe shoe is worn, producing'in effect a snug fit at the ankle.
The whole element is preferably made of spring metal and the wing portions are preferably sufliciently thin to be flexible. The beneficial effect on the foot of arching or corrugating the base plate is aided by the use of the leather or rubber cap shown at in Figures 2, 3, 5, and 6.
The base plate may be arched upwardly or downwardly, that is, it may be convex or concave or it may be circularly arched, that is, domed. It may be soconstructed with respect to the wing-elements that it fits into place in a shoe at the heel, at the arch or in front of the arch. Likewise the wing-elements may be located entirely adjacent the back walls of the shoe as in Figure 3 or they may extend further forward as indicated by Figure 4.
I believe that it is basically new to incorporate muscles. I
It is understood that other materials than metal may beused in the construction of my device,
the essential "requirement'being that the material used should be capable of exerting spring-tension force under the described conditions. Although the figures only diagrammatically portray my invention, the wings, in the preferred form, are
shaped to be substantially form fitting adjacent but below the ankle.
Special attention is called to the modification shown in Figure 5. In this example the force of spring tension is exerted by the base plate 3 and also, to a predetermined extent by the rear portion 4. The extent to which spring tension is exerted by 4 depends partly upon the tension put into it when shaped; it also depends upon the nature of the material out of which it is forged. For example, when made of spring metal or equivalent it may be so shaped that it exerts continuously a slight tension on the wings in their upper portions tending to bring them together; this tension may be greater in one portion of the wings than another according to design, shape and thickness of' the material of which the wings and 4 are comprised. Additional spring tension is exerted on the wings when a downward pressure is exerted on base plate 3. The force of spring tension on the wings applied by 4 is usually less at the front portion of said wings than towards the rear; the inward tension applied by ,3 is greater at the upper portion than at the base of said wings. These two forces are coordinated to produce the desired supporting ifect.
