SKI

Filed Sept. 22, 1950 Emy Mar/U5 EHKSen INVENTO:

Patented Nov. 22, 1932 PATENT OFFICE EMIL MARIUS ERIKSEN, OF BESSERUD, NEAR OSLO, NORWAY SKI Application filed September 22, 1930, Serial No. 483,437, and in Norway September 27, 1929.

Skis which are to be used for distance runs are made as narrow as possible in order to reduce their weight. This causes, however, some difficulties as regards the securing of the toe irons of the tie because the fastening screws will have to be placed so near to the edges of the ski, that sai-d' screws are liable to cause splits or cracks in the ski. A further drawback in such skis is that the middle 0 portion thereof is liable to be bent downwardly when in use, so that the ski, as is commonly said, digs or burro-ws into the snow.

The present invention aims at removing said drawbacks. According to the invention the ski is provided at each side of the portion where the tie is to be placed, with projecting Side parts which provide an increase of the material in which the securing screws are to be inserted and at the same time increase the carrying surface of the ski, so that the said digging action is counteracted.

Said projecting side parts may, according to the invention, consist of separate battens which are in a suitable way secured to the ski proper. Thus no blank of greater size than usual is necessary for the proper ski, and if desired the battens may be used on common skis already on the market.

The annexed drawingr illustrates by way of example some embodiments of the invention.

Figs. l and 2 are a side view and a top view respectively of the middle portion of a ski according to the invention.

Figs. 3 and 4 are similar views of a modified embodiment.

Fig. 5 illustrates a section on line V-V in Fig. l and Fig. 6 a section on line VI-VI in Fig. 3.

In Figs. l, 2 and 5 the ski is at each side provided with an enlargement or projection 2. Said projections extend along the ski substantially the length of the ski runners foot, backwardly from a point somewhat in front of the place where the toe irons are secured to the ski. At the front and rear ends said enlargements are inclined, so that they do not oppose the movement of the ski through the snow to any substantial degree. A preferred cross section of said enlargements is illustrated at Fig. 5, but obviously other cross sectional shapes thereof may be used if desired, thus the side thereof may be straight or concave.

Figs. 3, 4 and 6 illustrate a modified embodiment of the invention, where the enlargements 2 consist of separate battens which are secured to the ski l proper in a suitable way,

for instance by means of screws 5 as illustrat- 60 preferably are of a thickness equal to that of the rubber layer 8 usually used on skis.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed I declare that what I claim is:

l. A ski comprising a runner having upright longitudinal sides provided with a protruding portion on each side to form a broad foot support, each protruding portion being flush with the top of the runner along its upper surface and tapered inwardly towards its lower edge to meet the upright side of the runner along a line spaced substantially above the lower edge of the runner, the protruding portions being further tapered at the-ir opposite ends to meet the sides of the runner.

2. A ski, as claimed in claim l, in which said protruding portions are substantially triangular in cross section.

3. A ski, as claimed in claim l, in which said protruding portions consist of separate battens secured to the ski proper.

4. A ski, as claimed in claim 1, in which said protruding portions consist of separate battens secured to the ski proper, said battens being provided with flaps secured t0 the ski.

In testimony whereof I affix my signature.

EMIL MARIUS ERIKSEN.
