Qbject of this invention i a-ski fitting. Ski fittings with a pull member encircling the heel of the rider and with a tightener to tighten the pull member for holding the boots against the toe holding irons of the skis are already known. In these devices, either a spring encircling the heel of the boots is inserted into the pull member, or a resilient means arranged between tightener and pull member in the fore part of the fitting. These constructions merely allow of afine adjustment, that is, the correction of alternations caused by skiing either on the boots or on the pull member. This adjustment could only amount to some millimetres so that it was necessary either to have several pull organs of different lengths or to shorten the pull member when mounting, which shortening, however,- could only be carried out by men skilled in the art.- A standard fitting with adjusting possibilities allowing of an adaptation to any ize boots in question was lacking;

The ski fitting according to the invention remedies these inconveniences. It comprises a pull member encircling the heel of the rider, ends'of which are. fixed to a fore pulling device. An adjusting screw connects the pull member with the tightener.

By preference, the adjusting screw may be provided in the interior of a tension spring arranged between the webs of a tightener of U-shaped cross section. The head of the adjusting screw may'be pivoted on the tightener or, on the contrary, the spring, with its one end, may be pivoted on the tightener and carry a nut on its other end which engages the adjusting screw. In a preferred embodiment the two ends of the pull member may be attached to a connecting piece whose symmetry plane is inclined with regard to the axis of the adjusting screw; the advantages resulting therefrom will be shown later on.

The accompanying drawings illustrate, by way of examples, various embodiments of the ski fitting according to the invention, of which only those parts are shown and described relating to the invention.

Fig. 1 is an upright projection, and

Fig. 2 a top view of a first embodiment,

Fig. 3 is an elevation of a second and Fig. 4 of a third embodiment,

Fig. 5 is an upright projection and Fig. 6 a plan view of a fourth example and Figs. '7 and 8 show an elevation and a top view of a fifth form of performance.

Referring to Figs. 1 and 2 the pull member in the form of a cable I encircles in a non-illusthus fixing the piece 3 with the cablel to this spring. A nut 8 is threaded into the other end of the spring I, engaging an adjusting screw 9 whose head is pivoted on a lever H by means of the pin ID. This lever is'U-shaped and pivots 12 are mounted on its webs which engage the teeth [3 of'a lug I4 screwed to the Ski. I

From Fig. 1] it may be seen that the median plane X-X of the connecting piece 3' is inclined with regard to the axis yy of the spring I and screw 9, so that two diiferent positions can be given to the connecting piece and thereby to the cable so that, when placing the boot on the ski, one can install the cable for a diagonal or horizontal pull.

When the lever II, with the parts connected to it, is attached to the lug H by means of the pivots I2 and the teeth l3, the nut 8 can be displaced along the screw 9 by rotating the cable; the connecting piece and the spring 1. In this way the length between the pin l0 and the heel of the rider can be adjusted u to a degree which only depends on the length of the screw. The latter can be made very long, e, g., almost as long as the spring 1 so that the coarse adjustment possibl in this way (e. g., 1 to 6 cm.), is sufficient to adapt, at any previously adjusted position of the pivot l2 on the teeth l3, the ski fitting to any practically existing size of boots.

Formin the tightener as a U-shaped lever and placing the spring with the adjusting screw in the interior of this lever represents, besides the small weight and great moment of resistance, the further advantage of a simple construction and a very small space required.

In Fig. 3 only the lug I4 is modified with reard to the embodiment shown in Figs. 1 and 2. Here the teeth l3 ar not provided on openings of the ears of the lug but on the upper border of these cars, allowing of an easy removal of the whole harness from the ski before transporting the latter. Taking away the harness from the ski is also a good safety measure against theft of the snow shoes.

The ski fitting shown in Fig. 4 resembles the 26 is threaded into the spring which is pivoted to the lever H by means of the pin ID. The ears of the lug might also be formed as those shown in Fig. 1, that is, the teeth might be provided on an opening of the ears.

In Figs. 5 and 6 the screw 9 is, as in Fig. 4, attached to the connecting piece 3. However, at the right-hand end the spring has a hook I 5 engaging a loop l6 pivoted on both its sides on the tightener I! by means of a pin [8. Lever I! is pivoted on the lug or bracket 20 by means of the pin I9. Here, the possibility of adjusting the tightening lever in teeth, as shown in the previous embodiments is lacking, it might, however, be provided. Any adjustment of the pulling device takes place by rotating cable I and connecting piece 3, displacing in this way the screw 9 in the nut B.

The device illustrated in Figs. '7 and 8 resembles the one shown in Figs. 1 and 2. However, the lug l4 screwed to the ski is shaped in such a way that the pivots l2 can be taken out of the lug I4 without being dismounted from the lever I I. For this purpose the ears of the lug M, on the right of the hindmost tooth l 3 are formed as a guide 22 through which the pivots l2, flattened for this purpose on two opposite sides, can pass to the outside. In' this way the advantages of the lugs M of Figs; 1 and 3 are combined.

What I claim is:

1. In a ski fitting, a connecting piece, a pull member connected to said connecting piece, a lug, a tightener 0f U-shaped cross section, pivoted on said lug, and a connection device between said tightener and said connecting piece, comprising a tension spring lying between the webs of said u -shaped tightener, and an adjusting screw rotatable relatively to said tension'spring.

2. In a ski fitting, a connecting piece, a pull member connected to said connecting piece, a

- rotatable with regard to a tightener of U-shaped cross section, pivoted on said lug, and a connection device between said tightener and said connecting piece, comprising a tension spring pivoted to the webs of said U- shaped tightener and provided with a nut, and an adjusting screw fixed to said connecting piece and engaging said nut.

4. In a ski fitting, a connecting piece having a symmetry plane, a pull member connected to said connecting piece, a lug, a tightener of U-shaped cross section, pivoted on said lug, and a connection device between said tightener and said connecting piece, comprising a tension spring lying between the webs of said U-shaped tightener, and an adjusting screw rotatable with regard to said tension spring and th symmetry plane of the connecting piece being inclined with regard to the axis of the adjusting screw. 7
