SKI

Filed Aug. 10, 1951 Patented May 10, 1932 UNITED GEORGE S. STEVENS, F BOSTON, MASSACHUSETTS SKI Application filed August l0, 1931. Serial No. 556,213.

This invention relates to novel improvements in skis. Vith the prevailing types now in use the toe clips are attached direct- 1y to the skis by means of large wood screws.

In order to avoid splitting the wood of which the ski is made7 it is necessary to drill the wood with two different sizes of drills in order properly to fasten the screws. Users of skis do not generally possess proper tools nor skill for doing this work. Furthermore, in case of any adjustment to be made, these screws must be loosened, and in a short space of time will not hold tight. In addition to these points the distance between the screws is fixed and thus does not permit variation of any extent in the angle between the vertical part of the toe clip and the edge of the ski. Further, where the attachment of the toe plate to the ski is localized at the toe there is considerable tendency to breakage.

It is an object of my invention to improve the connecti on between the toe clip and the ski by extending the metal foot plate a sufcient length to extend beneath the entire sole and heel of the boot thereby preventing the accumulation of snow on top of the ski under the boot.

It is also an object of my invention to have the metal foot plate rigidly and permanently attached to the ski over an extended distance to thus avoid danger of splitting the ski or localizing the connection to the areas immediately beneath the toe.

A further object of my invention is to provide an improved and flexible adjustment of the toe clips relatively to the foot plate without loosening the attachment between the foot plate and the ski.

Other objects of my invention will be apparent from the following description of the preferred form as illustrated in the accompanying drawings in which;

Fig. 1 is a plan view of my novel foot plate Fig. 2 isa plan view of the same showing the toe clips in adjusted position;

Fig. 3 is a vertical longitudinal section on the lines 3 3 of Fig. 2 and Fig. 4 is a fragmentary side elevation thereof.

By way of example I have shown my invention to be applied to a wooden ski 5. The

metal foot plate G is long enough to extend beneath the entire foot of the boot. This plate 6 has reinforcing ribs 7 around its periphery and transversely of the plate. A. series of counter-sunken wood screws 8 are attached as indicated to the foot plate and run into the top surface of the ski 5. As is indicated Vin Fig. 1 the upper surface of the front of the foot plat-e is 'kn-urled or otherwise roughened to form an adequate frictional contact with the toe clips. This roughened area carries two round holes 9, 9 by which the toe clip attaching means is held. y

Behind the holes 9, 9 is a second pair of holes 10, 10. The latter` holes are elongated longitudinally of the foot plate 6'.

As shown clearly in Fig. 3 a series of bushings 11, 11 are held within the holes 9 and 10. These bushings have extended irregular bottom'flanges and a central screw threaded opening'.y Each flange is cut away along one side so as to be held against turning by the adjacent longitudinal stiffening rib. rThe bushings in the holes 9.are fixed in position while those in the holes 10 may move longitudinally during the adjustment of the toeclips.

The toe clips or plates 12, 12 are comprised of a base 13 and side portions 14. The side portions 14 have strap openings 15 and in the rear have ears 16.

A strap fitting 17 attached to strap 18 is held in ear 16 by means of fastenings 19.

The base 18 of toe plate 12 has a pair of transversely lelongated holes 20, 20. These holes have depressed flanges 21 upon which rest the flat head bolts 22 Hush with the top surface of the plate 13.

T he bolts 22 are threaded into the bushings 11 by means of screw threaded shanks 23.

From the above description it'will be readily understood that l have provided a foot platev 6 with even distribution of the attachment to the ski 5 by means of the numerous screws 8. At the same time by reason of the reinforcement 7 a space is provided in which the bushings 11 may freely turn or slide to facilitate adjustment of the toe clips.

fit)

The toe clips are roughened on their lower surfaces to engage in a positive manner 0n the upper knurled surface of the plate 6 and thus retain any adjusted position given them.

By means of the flat head bolts 22 holding in the bushings 11 the toe plates may be firmly fastened to the plate 6. Suitable adjustment both as to wid-th of the toe plates and inclination of the vertical sides 14 is permitted by having the laterally extended openings 20 in the toe plates and the coacting longitudinally extending openings 10 in the foot.

It will be readily seen how thev toe plates may be given any desired adjustment and securely fastened. Also the attachment of the wooden ski is securely accomplished without danger of the screws working loose orv the wood splitting.

While the preferred form of my invention has been described and illustrated I desire it to be understood that no limitation is implied other than what is consistentwith the scope of the appended claims.

What I claim is:

l. In combination with a ski, an extended foot plate attached thereto, said foot plate having a frictional surface, toe clips having f'rictional lower surfaces, and means for fastening the toe clips with their frictional surfaces in extended co-acting'engagement with the frictional surface of the foot plate.

2. In combination with a ski, an extended foot plate attached thereto,l said foot plate having a frictional surface, toe clips having fricti'onal lower surfaces, and means for f'astening the toe clips invariable angular relationship with their frictional surfaces in extended co-acting engagement with the frictional surfaces of the foot plate.

3. In combination with a ski, an extended foot plate attached thereto, toe clips, pivotal fastening-s between the forward portions of the toe clips and the foot plate, and laterally slidable fastenings between the clips and plate in rear ofV said first named fastenings.

4. In combination with a ski, an extended foot plate attached thereto, flanged bushings wholly above the top surface of the ski and extending upwardly through the foot plate,

toe clips mounted on the upper surface of the foot plate, and fastening means on said clips attached to said bushings.

5'. In combination with a ski, an extended foot plate attached thereto, a flanged bushing held by the foot plate, a second flanged bushing slidably held by the foot plate, a toe clip and means on said clip for fastening it to each of said bushings.

In testimony whereof I` have affixed my signature.

GEORGE S.. STEVENS.
