(Cl. 36-85) The present invention relates to shoes particularly sports shoes, for example, skating boots.

Ice skating boots must fit closely around the heel immediately below the ankle. It has been proposed to incorporate, in the upper, pad-like supports situated on opposite sides of the foot immediately beneath the ankle for the purpose of ensuring a close fit of the boot at that point and providing efiicient support. Such boots are expensive to manufacture as they have to be specially made and fitted. The supporting pads if made of steel are comparatively rigid and so likely to fit either too tightly or too loosely. If of leather or synthetic material having similar properties they are often affected by the combination of heat, perspiration and pressure.

The invention comprises two pad-like supports for application to or incorporated into the shoe article of footwear. These pads are intended to lie on opposite sides of the foot and provide supports in the vicinity of the ankle. Means is provided for drawing said pads into firm indirect engagement with the foot to provide efiicient support.

The supports should not project from the surface of the boot to an extent which might cause the wearer to trip when skating or should be as unobtrusive as possible, in the form of an external fitting.

Preferably, therefore, the pads should be actually incorporated into the boot to lie within the upper with the adjusting external so as to be accessible for adjustment. In that way adjustments can be easily made when the boot is being worn. The boot need differ only slightly in appearance from a boot of normal construction. The support can easily be incorporated into a boot during manufacture or may easily be applied to an existing boot.

In order that the invention may be clearly understood and readily carried out the invention is hereinafter described With reference to the accompanying drawings in which:

Figure 12 is a section on the line I--] in Figure 11. V

In the construction illustrated by Figures 1 to 5 of the accompanying drawings the suport is shown built into an ice skating boot. The support includes two metal bladetates Fatent O i 2,763,071 Patented Sept. 18, 1956 ice likemembers 1 carrying rubber or likepads 2 at their inner faces. Theparts 1 and 2 are introduced between the upper 3 and a leather orother stiffener 4 lying adjacent thelining 5.

As will be seen clearly from Figure 1 the blades and their associatedpads 2 are shaped so that they lie below the ankle and extend rearwardly into a position in which they lie partially around the heel. Theblades 1 at their forward ends projecting downwardly to a point where they are connected with twoplates 6 which are so mounted as to permit of the blades and their associated pads being moved angularly towards one another to grip the foot indirectly and give the necessary heel support.

In the arrangement shown twoplates 7 are screwed to the under surface of theboot shank 8. The plates are slotted at 9 to receivecranked projections 10 on theplates 6. The arrangement is such that theplates 6 are permitted a limited amount of angular movement in a vertical plane.

Theblades 1 are drilled at their lower ends to receive securingscrews 11 which pass throughholes 12 in theplates 6 and throughholes 13 inmetal brackets 14 which accommodate the blades at their lower ends. The holes in thebrackets 14 are tapped to receive the threaded parts of the securingscrews 11. Thesecuring screws 11, therefore, not only hold theplates 6 in position on the outside of the upper, but also connect theplates 6 in a rigid manner with the blades and their associatedbrackets 14. The manor of connection is clearly shown in Figures 2 and 3.

Theblades 1 and their associatedpads 2 can thus be drawn inwardly towards each other and angularly about theslots 9 in theplates 7. The method of angular adjustment is shown clearly in Figure 2. Each blade is formed with ahole 15 to accommodate thehooked end 16 of atie rod 17. Eachtie rod 17 passes through the boot lining and thence through the downwardly inclined holes bored through the shank. The extremities of thetie rod 17 are screw-threaded to receive adjustingnuts 18 which lie incountersunk recesses 19 in the under surface of the shank so as to be accessible to a screw-driver or other suitable tool.

The left boot is illustrated in Figures 1 to 5 and as will be seen clearly from Figure 3 theinner blade 1 has associated with it two tie rods whilst theouter blade 1 is associated with a single tie rod, the single tie rod passing between the pair of tie rods associated with the opposite blade. It is possible, therefore, with this arrangement to bring greater pressure to bear on the inner blade than the outer so that the foot can be more adequately supported on the inside than on the outside.

It will be appreciated that thetie rods 17 move the forward parts of the two blades bodily inwards when the adjusting nuts are tightened and although this adjustment may be adequate it is preferred to provide a further adjustment at the back of the heel. In the construction shown each blade carries anextension piece 29 which may take the form of an elongated wire loop, the extremities of the loop being bent inwardly at right angles and flattened slightly to a substantially dove-tail shape. The blade is formed with twoholes 21 of substantially key-hole formation, the walls of the narrow part of each hole being under-cut to accommodate the dove-tail parts 22 so that they will maintain their position therein. Theextensions 20 are held in postion on the blade by means of securingscrews 23 passing through aclamping washer 24, the clamping washer andscrew 23 lying on the exterior of the upper.

The greater part of theextensions 20 lie within the upper, but they project therefrom at thepoints 25 indicated in Figure l. The loop extremities are connected together by a threadedtie bolt 26 carrying at oneend 20 together and the blades and their associated pads into indirect gripping engagement with the heel.

The greaterpart of the-support will be hidden from view as it: is. accommodatedbetween the upper and the lining. 'OnlYthe plates dandtheheel adjustment member 26 and clampingwashers 24 project from the upper and in; no way detract from the otherwise smooth flush appearance of the boot. if necessary the leather or other internal support dumay. be cut away to permit or freer inward movement of the parts. The pads may be secured to the blades in any. suitable way as, for example,

by means of.adhesive tape 27 diagrammatically illus.-. With the construction. described.

trated. in Figure 3. above the support may alternatively be incorporated into the boot during. manufacture or may be introduced at a later; date. This can be done merely by cutting the stitches. at-the mouth of the boot connecting together. the upper; and lining and, introducing the blades. and their associated pads downwardly into their operative position. The upper is cut a minimum amount. The cuts are hidden from view by theplates 6. Theplates 6 in addition serve to clamp the out parts of the upper and prevent any possibility of the upper splitting when the; boot; is worn.

Figures 6 to illustrate a modified construction which is somewhat simpler than that previously described, butwhich does notincorporate the additionaladjustnient at the; back of the heel. It is intended that the blades; 1- shall'initially be bent so that they in themselves tit snugly on; opposite sides of the foot. The blades are moved bodily inwardly with the simple form of adjustment employed.

The blades in this construction are of substantially T shape, although they may be of a shapemoreclosely simulating a. Y. The normally horizontal limb of the T isdownwardly and forwardly inclined. so that it fits snugly beneath the ankle bone. Thethird limb 28 of the T projects downwardly and is located. in a recess 29:

formed in the outer surface of theheel 30.

It is intended that the blades shall be pivoted inwardly about their. lowermost edges and so therecesses 29 are of. the wedge or tapering crosssectional shape shown in Figure 7. Theblades 1 and their associatedpads 2 are drawn bodily inwards towards each other by means oftwotierqds 17 which are arranged in a somewhat similar inclined manner to those shown in the previously described arrangement. The tie rods in this case, however, passthrough the heel as distinct. from theshank.

One end-of each tie rod is bent over into the form of ahook 16 which in this case passes around aU-shaped lug 31*carried by the blade. The opposite end of the tie rod passes through a hole drilled in the opposite blade and being'screw-threadedtoreceivean adjusting nut 18. Tightening of the adjustingnuts 18 will draw the two blades and their associated padsbodily towards one anotherinto good indirect gripping engagement with the foot to provide the required support. Each adjusting nut ls'takes the form of a shouldered nipple, The tapering head of this nipple has aclearance 4 in a countersunk hole in the blade (see particularly Figure 8), thereby to a certain extent retaining the blade in position without restrictingits freedom to swing. Theshoulder 45 on the adjusting nut engages a washer 46 through which the shank of the nut passes. The washer becomes a reaction point for the blade in the form, for example, of arivet 47 whichv is soldered in position in the washer. The shank of the rivet is located in a hole boredin the heel.

Referring to Figures 9 and 10 it will be seen thatif thev rivet is located centrally as in Figure 9 the efiective lengths of arms A and B will be equal. But if the rivet is located other. than centrally, as in Figure l0, arms A and B will be unequal thus providing a degree of unbalanced pressure on the foot if required. It will be seen also that the washer serves to spread the reaction load from therivet head over a reasonablearea of leather.

As the upper must necessarily be cut to allow thedownwardly depending limbs of the blades to project, the cut is covered by means ofplates 6 which are generally similar to theplates 6 described in connection with the previous arrangement. Theplates 6 are held in position by meansof-scre-Ws 11 which enter threaded holes formed in bosses 11a carried by the blades. Theblades 6 are provided withadditional holes 32, for the passagev of the adjustingnuts 18 thus exposing the nuts for adjustmentpurposes.

In the further modified construction shown in Figures 11 to 12 the adjusting mechansm is more apparent as it is mainly disposed on the exterior of the boot. The blades in this case are moved bodily inwardly by two adjustments, i. e., an adjustment lying beneath the shank and by. a heel adjustment on the backof heel.

In this construction the adjustment takes the form of twolevers 33 arranged on opposite sides of the bootand on opposite sides of the shank. The levers each carry afulcrum pin 34 mounted for angular movement in a pair ofeye members 35 which are driven through the shank. The lower ends of the levers are bent inwardly substantially at right angles as at 36 and are drilled and tapped to receive adjustingscrews 37 which. bear on the under surface ofthe shank.

Thelevers 33 carry at their upper ends an upwardly.inclined extension 38 which is connected withits. asso ciated blade at thepoint 39. Thepartsare connected: by means of a securing screw, a clampingwasher 40 and.

42 projects through the holes to the exterior of the upper and extends into a position at the rear of the heel where theparts 42 can be drawn. together with the assistance of a suitable form of heel adjustment. adjustment may be similar to that described in connection with Figures 1 to 5. The adjustment in any case pref erably includes an adjustingnut 43. When tightened this nut serves to bring theparts 42 and their associated blades nearer together to produce the required gripping effect on the heel A It will be appreciated that the construction disclosed by Figures 11 and 12, although not. being so neat asthe two constructions previously described has the merit of simplicity. It can be easily applied to an existing boot with a minimum of alteration. The blades are adjustable individually'by individual tightening up of the adjusting screws 37 beneath the shank.

It is preferred to construct the bladesfrom steel the pads being; composed ofa comparatively soft material such as, for example, sponge rubber.

Although shown-as applied to a skating boot the padlike supports may be used with any other type-pf foot wear where heel support is important.
