Description

ru -M July 26, 1955 J. GUEST FOOT-ARCH SUPPORTS Filed Dec. 15, 1951 INVEN 10 James Guest United States Patent FGQT-ARCH SUPPORTS James Guest, Bolton, England Application December 13, 1951, Serial No. 261,514
Claims priority, application Great Britain October 1, 1951 4 Claims. (Cl. 36-71) This invention relates to foot-arch supports, and is an improvement in or modification of that which forms the subject of my prior Patent No. 2,553,451.
In the specification of that patent I have disclosed a foot-arch support for application to a boot or shoe sole otherwise than at the inner side thereof, and which comprises a rigid stiffener element adapted, when in use, to extend forwardly from the heel at least to beneath the ball of the foot, that part of the support which lies beneath the transverse arch of the foot during wear of the appliance having its underside convexly shaped so that the support acts as a lever of the first order with its fulcrum constituted by the convexity aforesaid or a covering applied to the latter.
The present invention is based upon an appreciation of the fact that the use of longitudinal ribs makes possible an extremely light and strong construction of footarch support which will provide in use the same highly advantageous levering action as do the supports described in my prior patent, whilst having no transverse rib as such.
According to this invention, a foot-arch support, designed to produce the levering action in use characteristic of the support disclosed in my prior patent aforesaid, is pressed from relatively thin sheet metal in such a manner as to exhibit at its underside a plurality of laterally spaced longitudinal ribs whose forward ends are rounded and disposed (when the appliance is in wear) beneath the transverse arch of the foot to collectively provide a fulcrum for the levering action above-mentioned. The front is under the ball of the foot and is a lever arm on which the effort, or the wearers weight, is applied. That portion to the rear of the fulcrum is a lever carrying the load which is the bony structure of the foot. This structure constitutes a lever of the first class or order here the fulcrum is between the effort and the load.
Preferably the foot-arch support is permanently secured to the inner sole of a boot or shoe, the outer sole of which covers at least the front portion of the support and is deformed by the ribs thereon so as to act as a fulcrum in lieu of the latter.
in the accompanying drawings:
Fig. 1 is an underside plan view of one form of the improved foot-arch support intended for permanent incorporation in the sole of a boot or shoe.
Fig. 2 is a section on the line 2-2 of Fig. 1, and
Fig. 3 is a section on the line 3-3 of Fig. 2.
In the construction illustrated, the stiffener element A of the improved arch-support is pressed to the desired form from a suitably shaped blank of relatively thin sheet metal; for example, an aluminum alloy. The thickness of sheet employed may be of the order of one'sixteenth of an inch.
The configuration of the stiffener element A in side elevation conforms to the curvature of a boot or shoe inner sole (indicated at B) from the breast of the heel C at least to a position beneath the ball of the foot when the boot or shoe is in use. Furthermore, the appliance 2,713,732 Patented July 26, 1955 is pressed with a suitable transverse camber as clearly shown in Fig. 3.
It is proposed to produce such stiffener elements in a variety of different sizes or half-sizes corresponding to those normal in footwear.
As applied to a size 8 mans shoe, the stiffener element A may be some 5 inches long, so that when its rear end is abutting the breast of the heel C, its front portion D will extend an inch or more forwardly of the average position of the wearers transverse arch.
The shank portion E of the stiffener element is formed, during the pressing operation, with a plurality of dependant ribs F of arcuate cross-section, which extend longitudinally of the appliance in side-by-side relation. Although shown as terminating about inch from the rear edge of the stiffener element A, these ribs may be continued to such edgeif so desired, and in either case they are of such a length as to bring their rounded forward ends beneath the position of the wearers transverse arch.
For convenience, there are three such ribs F, one arranged approximately on the longitudinal centre-line of the appliance, and the others in forwardly divergent relation thereto, the distance of each outer rib from the central rib being about /2 inch at the rear and 1 inch at its forward end.
The height of each rib (measured from the undersurface of the stiffener element A) may be some A; inch at the front and may progressively diminish towards the rear of the appliance.
The shank portion E of the stiffener element is preferably formed at its inner edge with an integral upwardly directed extension G which, when the appliance is fitted to a boot or shoe as hereinafter described, co-operates with the side of the upper to support the longitudinal arch of the foot.
The improved appliance is intended for permanent incorporation in a boot or shoe, and for this purpose it may be initially located upon the inner sole B by means of two rivets or screws H placed near opposite ends of its longitudinal centre-line (i. e., adjacent the extremities of the central rib F).
As shown in Fig. l, the transverse dimensions of the stiffener element A are such that its outer edge, and the forward portion of its inner edge, leave exposed a suflicient marginal width of the inner sole to permit sewingon of a full-length outer sole B in the normal manner. Where the lateral extension G of the appliance conceals the edge of the inner sole, the corresponding portion of the outer sole B may be secured by a row of rivets or screws passing through holes I.
In the event of the tread portion of the outer throughsole becoming worn, such sole may be completely replaced in known manner, or alternatively the tread portion only may be cut away and replaced by a half-sole whose rear edge is cemented to the stiffener element and also secured thereto by further rivets.
When the appliance is being applied to used footwear, the outer sole is completely removed and the stiffener element secured to the inner sole B by rivets or screws passing through holes H and I as aforesaid, after which a halfsole is affixed, by sewing, cement, and rivets, the shank portion of the appliance being left exposed and preferably painted to match the footwear.
In such a case, the lateral extension G (suitably painted) will be wholly external to the boot or shoe, whereas when the appliance is incorporated in new footwear, it is preferred to conceal such extension between the material of the upper and the lining therefor.
Whichever arrangement is employed, the front portion of the stiffener element is built into the thickness of the footwear sole, and the outer layer B of the latter is de- 3 formed by the rounded front ends of the ribs F, the height of which raises the toe end of the sole by a corresponding amount, in addition to the elevation imposed by its normal upsweep or cast.
In wear, the increased elevation of the front end of the sole is scarcely noticeable, and if desired the appearance of the footwear may be improved by thickening the toe end of the sole to obviate any pronounced shoulder at the front of the stiffener element A.
In operation, the improved appliance maintains the shank portion of the sole rigid, the weight being taken upon the ridged area I of the outer sole B covering the front ends of the ribs P, so that the metatarsal bones are not affected when the wearer is standing still.
During walking, however, the weight is transferred to the front portion D of the stiffener element A, which thereupon acts as a lever of the first order, having its fulcrum at the ridged sole area I. The foot is thus flexed in a normal manner and the upthrust of the shank portion E gently urges the bones of the foot towards their correct positions.
What I claim is:
1. A foot-arch support comprising a thin sheet of rigid material, the length thereof being such that it extends from the breast of the heel to beneath the ball of the foot of the wearer, said sheet being of substantially uniform thickness throughout, a plurality of laterally spaced longitudinal ribs at the underside of said sheet, said ribs being spaced apart by substantially solid material, the front of said ribs terminating beneath the transverse arch of the wearer, the area at the front end of said ribs constituting a fulcrum of a lever of the first order, that portion forwardly of said ribs extending forwardly of said transverse arch and the remainder adapted to pivot about said fulcrum.
