11 Claims. (01. 2s0 1.s5)

My invention relates to foot-gear, particularly to means for attaching various types of foot-gear to the foot of the user, and is directed to an improvement in such means that is especially ap- 5 plicable to skis.- Thatthe principles of the in- H person.

1 couraged. Usually a tool is required, even when adjustment is contemplated by the manufac-. turer. Such adjustability as offered heretofore is generally too limited inkind and scope to per mit adequate and satisfactory adaptation to a variety of foot-sizes. "As a result, -a' pair of skis having the prevailing type of foot-retaining means is, in practice, restricted to the use of one The general object of my invention is to provide, in a foot-attachment for skis andthe like, quick, convenient, and flexible adjustability over an extensive range of normal foot requirements,

. a such adjustability as will encourage the practice or" putting a given pair of skis into the service of several persons.

It is my purpose to provide flexibility in with, 7

length, and in tightness of fit over the wearers foot, to the extent that the ski may be readily adapted to a normal foot in any combination of adjustments preferred by the individuals. A feature of my invention following from such wide adaptability is thatrthe wearer may compensate for changes in stretch of material in the footattac-innent caused by stress in use, or caused by wetting and drying of the material, and may also change the adjustment from time to time with'change of personal preference. These considerations are of major, importance in the use of water skis, where confidenceon the part of the wearer and the avoidance of injuries requires that the foot-attachment be adjusted in some respects for snugness .to provide adequateccntrol over the ski,-and'be adjusted'loosely in other respects to permit the wearer to discard the ski instantly in an emergency. Other objects and advantages of my invention, especially those relating to the comfort of the wearer and those relating to efficiency of engagement with the wearers foot, will be best understood by reference to the detailed description to follow.

Broadly described, myinvention comprises a forward pair of adjustably spaced foot-retaining members, a flexible member associated therewith to extend adjustably over the wearers foot, and means to engage the heel of the wearer, relative movement being provided between said means and said forward members.

In the accompanying drawings,

Fig. 1 is a plan view of a ski, on a reduced scale, showing my attachment mounted thereon for the left foot of the wearer;

Fig. 2 is a plan view, on a larger scale, of the central portion of the ski, .showing my attachment adjusted for a relatively large foot;

' V Fig. 3 is a similar view with the attachment adjusted for a relatively small foot; Fig. 4 is a sideelevation of Fig. 3;

Fig. 5 is a longitudinal, medial section through Fig, 3, indicating the manner in which the wearers foot fits into the attachment; V

Fig. 6 is a transverse, vertical section taken as indicated by line 66 .of Fig. 5; and

Fig. '7 shows the under side of a flexible member prior to assembly.

Ski I9 is centrally increased in thickness in the usual manner, as indicated at H, for reeniorcement where the ski receives the weight of the wearer. The movable parts of my foot-attachment are carried by a base-plate 12, which is detachably mounted on the ski by suitable screws l3. A necessary clearance between the baseplate and the ski may be provided by spacers I l surrounding the screws, as indicated in Figs, 4 and 5. i 7

Since, in foot-gear, parts on the left side of the left -.foot correspond to parts on the right side of the right foot, the terms outside and inside will be substituted for left and right, the terms outside and inside here used being associated with the outer and inner sides, respectively, of whichever foot is involved.

My invention includes a forward pair of adjustably spaced foot-engaging members comprising outside toe-block l5 and inside toe-block it, and also includes'a rearward pair of heel-engaging members, outside heel-block H and inside heel-block i8. Preferably, as may be noted by comparing Figs. 2 and 3, relative movement between the pair of toe-blocks and the pair of heelblocks will be provided solely by movement of thejlatter. v

Toe-block i5 curves to conform to the general configuration of a wearers foot, and preferably comprises a horizontal base portion l9 resting on base-plate l2 and an upright flange 20 along the edge nearest the wearers foot, this flange extending across the forward end of base I9, as indicatedat 2|. I

The complementary toe-block I6, having a similar configuration, also has a horizontal base portion 22 and an upright flange 23 extending across the forward end at 24,

two toe-blocks, to conform with different footwidths, is provided by pivotally mounting them on base-plate l2 by their forward ends. The two toe-blocks may have a common pivot, the forward ends forming a hinge as shown. The knuckle of this hinge comprises two horizontal extensions 25 integral with end flange 2| of the outside toe-block, and two alternate, complementary, horizontal extensions 21 integral with end flange 24 of the inner toe-block, the pintle of the hinge being a suitable bolt 28, the lower end of which is non-rotatably mounted in baseplate 12. Bolt 28 is provided with a suitable hexagonal nut 29 that may be conveniently tightened by a suitable key or socket wrench to secure the assembly at any desired angular relation of the two members. Preferably, the underface of each of these forward members is roughened or corrugated, as indicated at 3|) (Fig. 4.)

Base IQ of toe-block I5 is apertured to receive a suitable bolt 32 that slidingly engages an arcuate slot 33 in base-plate l2 concentric with pintle 28. Preferably, the bolt has a square shank to prevent rotation in the slot when a hexagonal nut 34 on the upper end of the bolt is manipulated to clamp or unclamp the toe-block.

In similar manner, a bolt 35 having a nut 36 is provided for adjustably clamping toe-block I5 to the base-plate, the bolt engaging a complementary arcuate slot 31 also concentric with pintle 28.

Slots 33 and 3'! are of sufficient extent to permit adjustment of the two toe-blocks through the normal range of narrow and wide feet. It will be noted that upright flanges 23 and 23, in addition to confining the foot of the wearer, serve as guards to protect the foot from bolts 32 and 35.

In the form of my invention here shown, toeblocks !5 and It not only serve as means to restrain the ski against backward and lateral movement with respect to the foot of the wearer, but also cooperate with a flexible member 38 that serves as a casing extending over the instep to restrain the ski from downward movement away from the foot.

This casing, made of canvas or other suitable fabric, is secured at its forward and side margins to base-plate l2 by suitable means such as a U- shaped metal strip 39 and rivets 40. This flexible member extends under the two toe-blocks, having apertures registering with forward bolt 28 and the two arcuate slots 33 and 31, as well as with any screws l3 that would otherwise be inaccessible. This casing has the shape and construction of a shoe-upper, being slit longitudinally into two halves provided with hooks 4| adapted to be engaged by a shoe-lace 42. Preferably, a tongue 43 is sewn to the casing along an end and one side, as shown. The casing is laced up in the same manner as a shoe, the hook-and-lace construction providing means to adjust the casing for tightness of fit over the wearers foot.

Passing the flexible member under the toeblocks has several advantages. Among others, it prevents the foot of the wearer from coming into direct contact with the toe-blocks, and it also provides a yielding restraint tending to cushion, violent movements of the foot against the unyielding sides of the toe-blocks. An important advantage of the arrangement is that adjustment of the toe-blocks regulates the effective width of the casing. Thus, as the toe-blocks are moved towards each other to conform with a narrow foot, slack in the width of the casing is automent or. the ski with respect to the wearers foot,

and also to provide bearing surfaces to receive pressure laterally from the heel of the wearer for controlling the ski. A relatively loose fit meets these requirements and looseness rather than tightness of fit is essential to permit the wearer to discard the ski instantly in an emergency.

While a liberal tolerance in the fit of the heelengaging means is contemplated, nevertheless it is desirable that such means be adjustable in Width as well as in its spacing from the forward foot-engaging means. Since there is a certain correlation between lengths and widths of normal feet, at least a correlation that is commensurate with the tolerance of fit here permitted at the heel of the wearer, I find it convenient to combine adjustment in Width with adjustment in the longitudinal position of the heel-engaging means, i. e., to arrange the heel-engaging means to narrow automatically as it is moved forward towards the toe-block. I also find it desirable, where a pair of heel-blocks of the shape shown is employed, to cause at least one of the blocks to rotate slightly as the pair is adjusted forward, such rotation conforming to narrower feet. The drawings indicate how these desired functions may be provided by mounting the two heel-blocks in suitably disposed slots in base-plate l2.

Outer heel-block I'I comprises a base portion 46 and an integral upright flange 41 to form a bearing surface for the heel of the wearer, this flange at the forward end inclining away from the vertical as shown. The forward portion of the heel-block is retained by a suitable bolt 48 thru base 46, the bolt being slidably and, prefer ably, non-rotatably mounted in an oblique slot 49 in base-plate [2. The bolt carries a suitable hexagonal nut 50. It will be noted that flange 41, in addition tooffering a bearing surface to receive lateral pressure from the wearers heel, serves as a guard to prevent injury to the wearers foot by the bolt or nut.

The rear portion of heeleblock I! is secured by a second bolt 5| having a nut 52, the bolt being slidably and non-rotatably mounted in a second oblique slot 53 in base-plate I2. By disposing forward slot 49 at a slightly greater angle with respect to the longitudinal axis of the wearers foot than rear slot 53, I cause the heel-block to rotate inward to a slight extent as it is moved forward, the rotation being apparent in a comparison of Figs. 2 and 3.

The configuration of inner heel-block I8 is similar to that of heel-block I I, the inner heel-block comprising a base portion 55 and an upright flange 56, this flange inclining away from the vertical at the forward end. The heel-block is adjustably secured by a forward bolt 51 having a nut 58 and a rearward bolt 59 having a nut 60, both bolts being slidably mounted in a common, oblique slot 6| in base-plate l2.

The toe-blocks and heel-blocks shown may be made of any suitable material such as wood, metal, or compositions similar to that known by the trade-mark Bakelite.

The manner in which these two heel-blocks cooperate to engage the heel ofthe wearer will be apparent from the drawings, and the manner in which the spacing between the two blocks narrows as they are moved forward will be readily understood.

To adjust my foot attachment in accordance with the requirements and preference of a particular wearer, the various nuts are loosened, and the wearers foot is thrust forward on base-plate l 2 under flexible member 38 to fit snugly against the forward portions of the toe-blocks. The twotoe members are then adjusted to conform with the wearers foot and secured in their desired positions by tightening the three nuts 29, 34, and 36. The next operation, by preference, consists of moving the heel-blocks forward and seeming them into positions desired by tightening their associated nuts. The final step is to lace together, across the foot, the two halves of casing 38.

The procedure required to change the adjustment of the attachment completely from one set of requirements to a different set of requirements for a different foot size, is a quick, simple process of no great inconvenience, and yet the adjustment once made is safe and as permanent as may be desired. The whole foot attachment may be removed for transference from one pair of skis to another by simply taking out screws I 3 thru baseplate I2.

The specific example herein described, as illustrative of my invention, suggests various changes in arrangement and construction without departure from the principles involved; and I reserve the right to all such changes and modifications that fall within the scope of my appended claims.
