Description

28, 29 to the side portions of the heel strap 19 between the ends of such portions, the instep strap extending from the heell strap at a right angle or nearly a right angle. The sections 26, 27 are connected together by a clamping` member or lever 30 here shown as pivoted at 3l to lugs 32 provided at the front end of one side portion 27, the other side portion 2G of the instep strap being pivoted at 33 to the lever 30 near theouter end of the lever. After the foot has been placed on the foot plate 2 and into the toe strap and heel strap, upon the movement of the lever 30 into a position in which it folds along the side portion 27, the side portion 26 will be tightened acrossthe instep of the user.

The lever is held in its folded position by quick detachable means and, as here shown, a buckle similar to any arctic buckle is used, this comprising a hook-shaped lever 34 pivoted at 35 and coacting with a spring 36 which tends to hold it in either its open or closed position. When the clamping lever 30 is folded to its closed position, the lever 34 extends-around the bar 36 and, upon moving the lever 34 from its position shown in ligure 2 rearwardly, the lever 30 is locked in its folded position. The lever 34 can be quickly moved to its open position shown in Figure 2 and the lever 30 moved to its open position to permit a quick detachment of the foot from the ski.

V The side portion 26 of the instep strap, as here, illustrated, is folded upon itself around the pivot 31 and is provided witha plurality of eyes 38 into any one of which a hook 39, provided at the end of the folded part 40 may take, for the purpose of shortening or lengthening the side portion 26 of theinstep strap and adjusting it to the foot of the user.

In operation, the heel strap is adjusted so i that the joint of the large toe of the operator is directly above the pivot 3 of the foot plate and so that the toe of the shoe extends beyond thefront edge or fulcrum lb' of the foot lplate and overhangs the runner in such a. position that the toes of the shoe engages the runner when the foot plate is inclined a predetermined amount. By reason of the adjustment of the heel strap, the foot can be accurately placed on the foot plate so that the joint of the large toe and alsopoint of the shoe bears lproper relation to the hinge 3 and the upper face of the runner.

Also, by reason of the arrangement of the heel strap and the instep strap, the foot is practically held against up and down movement relatively to the foot plate 2 but is capable of slight lateral and endwise movements necessary to control or tov comfortably guide the runner, and the heel and instep' straps can move on their pivots during the movement of the ankle of the user. In

short, the operating of the runner is flexible and free of any binding or clamping action.

What I claim is:

l. In a ski the combination of a runner, and a foot plate pivoted on a horizontal axis at its front end to the runner, and having a downwardly extending shoulder at its rear end for engaging the upper face of the runner to space the plate from the runner to form a clearance for snow, the shoulder terminating in a comparatively narrow edge to cut through snow on the runner and prevent packing of snow on the runner, substantially as and for the purpose specied.

2. In a ski the combination of a runner, and a foot plate, pivoted at its front end on a horizontal axis to the-runner, and having downwardly extending flanges at its ksides and rear end, whereby the foot plate is boxshaped in general form, and a clearance for snow is provided between the top of the boxlike plate and the upper face of the runner, substantially as and for the purpose set forth. y v

3. In a ski the combination of a runner, a foot plate pivoted at its front end on a horizontal axis to the runner, and having lengthwise downwardly extending flanges at opposite edges thereof, the runner being provided with lengthwise faces inclined downwardly and laterally from substantially the median thereof, and located between such iianges, substantially as and set forth. Y

4. In a ski the combination of ak runner, afoot plate pivoted at its front end on a horizontal axis to the runner, and having lengthwise downwardly extending anges at opposite edges thereof, the runner beingprovided with lengthwise faces inclined downwardly and laterally from substantially the median thereof, and located between such flanges, the foot plate also having means at its rear-end for resting on the upper face of the ski in the rear yof said inclinedl faces, substantially as and for the purpose described.

5. In a ski the combination of a runner, and a foot plate pivoted at its front end on a transverse horizontal axis to the runner, the plate having an upwardly curved portion above its pivot, terminatingy in a fulcrum for the foot, above and in advance of the axis of the plate, substantially as and for the'purpose described.
