SKI FASTENER Filed Nov. 3, 1932 Patented Aug. 15, 1933 UNITEEE STATES SKI FASTENER Hans Jensen, Sarpsborg, Norway Application November 3, 1932, Serial No. 641,073, and in Norway February 20, 1931 5 Claims.

This invention relates to fasteners of the kind in which the sole of the boot secured to the ski by m ans of an eccentric device mounted in the toe clamping iron. The invention differs from the hitherto known devices of this kind in that the eccentric itself in combination with a covering secured to the sole of the boot serves as clamping member, the covering being so formed that the eccentric, in addition to pressing down the sole of the boot against the ski, also causes the sole to he moved forward a small amount in the toe irons and fixed in this position.

A constructional example of the invention is illustrated in the drawing.

Fig. 1 shows a toe clamping iron seen from the inside with a part of a sole with applied covering in cross-section on the line A--A of Fig. 3 in the position before being fastened.

Fig. 2 corresponds to the arran ement shown in Fig. l, the sole of the boot has been secured.

Fig. 3 is a plan view of the toe clamping iron turned through 90 with respect to Fig. 2.

Fig. 4 shows a part of a boot with a covering applied in side elevation.

Fig. 5 shows the boot covering in cross-section on the line B-B of l.

1 is a toe clamping iron of any known construction in which a pin 2 is rotatabiy mounted which is made in one piece with a circular eccentric 3 arranged eccentrically on the inner side of the toe clamping iron and intended for hearing against a covering 4 on the edge of the sole 5 of the boot. The part of the pin 2 projecting outside the toe iron 1 is formed with a icur-sided part for receiving a lever 6, which, by means of a screw nut '7, is secured. to the end of the pin which is threaded. Near the free end the lever 6 is provided with a locking pin 8 which, when the lever is pressed down, is brought into ment with one of the holes 9 of a series provided in the toe clamping iron and thereby secures the lever in position. in order to obtain reliable engagement of the loci g pin 8 one of the holes 9 and at the time to secure it, the lever 6 is made somewhat resilient so t always kept pressed against the outside of the toe iron. The cove 'ing 4 secured to the edge of the sole of the boot has an -shaped section and its upper surface has a raised part is intended to co-operatewith the eccentric 3 wh n the latter is depressed during the fastening of the boot. At each end the covering iis formed with a projecting point 13. which together with r the screw 12 ensures reliablefixing of the. covering to the edge of the'sole.

When the boot is to be fastened on, the lever 6 is first moved upwards (compare Fig. 1) so that the raised part 10 of the covering 4 secured to the sole 5 can pass freely under the eccenit is 7 trio 3 when the boot is pushed in between the toe irons. Then the lever 6 is moved downwards whereby the eccentric 3 bears against the raised part 10 on the covering 4 and causes the boot to be moved forward slightly so that it is tightly fixed between the toe irons and at the same time is pressed against the ski. In this position, which is illustrated in Fig. 2, the lever 6 is fastened by the bolt 8 being brought into engagement with the nearest hole 9 of the row of holes in the toe iron 1. As is clear from the drawing, the boot is then held rigidly and securely.

What I claim is:

l. A ski fastener having toe clamping irons, eccentric devices mounted on each of the toe clamping irons, and coverings secured to the sole of the boot and adapted to co-operate with the eccentric devices, the coverings being of such shape "hat the eccentric when rotated for'fastening, in a tion to pressing the covering with the the bottom plate of the toe iron, also causes the sole to moved forward between the toe irons.

2. .A ski fastener having toe clamping irons, eccentric devices mounted on each toe fastening iron, a covering secured to the sole of the boot and adapted to co-operate with the eccentric devices, and a raised part on the sa d covering which can pass th eccentric de .ce in the raised position thereof and against which the eccentric device bears when depressed so as to move the boot forward and press it downwards against the toe iron.

3. A ski fastener having toe clamping irons, eccentric devices on the toe clamping irons, and a covering secured to the sole of the boot and adapted to co-operate with the eccentric device securing the boot and oving it forward tween the toe irons, the covering being of L.- shaeed section and having at its ends projecting points which, when the covering is screwed to the sole, are forced into the sole and ensure satisfactory f xing.

4. A ski fastener having toe clamping irons, eccentric dev ces mounted on the toe clamping irons, a covering secur to the sole of the boot and adapted to cc-operate with tho eccentrics for securing the cost, a lever for turnim the eccentric and bolt on the lever engaging 'Wltl'l perforations provided in the toe iron for holding the eccentric in position.

5-. ski fastener as claimed in claim 4, in which the lever hears resiliently against the outer side of the toe iron.
