fittings for the fixingror attaching ,oluarticles known as skins orsubstitute thereof, to skis.

This invention involves a simple. manner of attachmenhby providing at least one group of and the other part with the ski. These elements by being .properly joined are capable of consti tuting a composite, securely connected whole; the elementsintegral-with the ski not extending beyond'thesole or. plane of the lower resting face of the latter.

The annexed drawing illustrates some embodiments of the invention given by Way of examples. Figs. land 2 are an upper viewand a side View of the ski supplied with a skin fixed by the means of fittings according to theinvention; Figs. 3 and 4 are an underneath view from below and corresponding cross section showing afirst embodi ment of a group of'elements; Figs. 5 and 6 are cross sections similar to that of Fig. 4 but concerning variations;- Figs. '7 and 8 illustrate two embodiments cl 3. fitting device belonging to a group'of elements, this device being intended to be placed in a longitudinal groove of the sole of the ski.

The ski of Figs. 1 and 2 is made of the wood l and of aretaining device 2. ,It is provided with a skin 3 stretched by means of fittings 4, its front extremity being fixed to the wood by a buckle 5 enclosing the tip of the ski, To increase the ad hesion of the skin to the ski,"the skin can be stuck to the latter by means of a paste independently of the fittings forming the features of the present invention. The groups of elements forming the fittings are three in number in the example shown and are to be found at 6, l and 3. At these same places, aswill presently be seen, the skin is rendered mechanically adherent to the ski. It is to be noticed at one of these places, that one member of a group of elements I is placed in the region of the ski to be found imout of the lower surface of the wood as in the I case of every ski. In this groove is placed an anchoring member iii having the main form of ahook like a U, but Whose length at the middle part should be relatively great, for example, a

multiple of the length of the branches. Fig. 7

In Switzerland illustrates such. a member of" which the I middle part H is effectively very long compareditozthe length of the prongslZ. Besides, to the skin is fixed a small metallic plate 13 the centre of which is cut out and bent back in order toform catches it of which the jaws'are directedthe one against the other and-enclose'tightly the'middle part oi=the hooked U-shaped 'member ill. The fixing of the small plate to the skin is accomplished by meansof rivets 15.

As can be seen member it does not project be of interfering with the proper gliding of the ski.

The connection of this member with the catch [4 is also effected in said groove 9. The setting in place and making of the connection or even disconnecting is effected in a very simple manner. To do this it is sufiicient to apply the part of the skin 3, to which is fixed the small plate l3, against the wood immediately at the sides of member II] for example, and above this member as in Fig. 3, and to accomplish the connectionby sliding in the direction of arrow 16. The operation of disconnecting is then'done by slidingin the opposite direction, the relative moving of the'parts to be connected being lengthwise.

To permit this jointing of the elements of a group it is clearly necessary that the hooked U- shaped member ll] orll, for example such as represented at Fig. 7, should be laterally notched at ll, that is to. say at the point where the middle part and the two branches are joined the one to the others.

Instead of notching laterally the hooked U- shaped member, it is possible to give to the middle part of the latter a trapezoidal cross-section as represented in thesection-view of Fig. 5 at l8. The part of this member emerging-from the wood then constitutes a dove-tail with which the catches of the small plate I3 can engage.

Instead-of forming the catches of said small plate by cutting up followed by folding back, it is equally possible to resort merely to a folding back, in giving for example to the small plate the shape shown in the side-view at E9 on Fig. 6. In that figure the said plate is representedas separated from ski l and from anchoring member ill enabling one to see thatit presents normally a convexed shape the concavity of which is turned towards the ski. This shape offers the advantage of securing a better application of the plate and consequently also of the skin against the ski, the setting in place requiring a certain amount of pressure to deform the plate and to flatten it against the wood. The elasticity it presents also makes it possible to take up on the wear of the lower face of the ski against which the edge of the Wings of the plate will always rest correctly.

Finally, instead of utilising an anchor member presenting in the main form of a U-shaped hook, one could utilise a similar member such as represented in Fig. 8 and showing several prongs 20, 2|, 22 allowing the same to be fixed in the wood. The middle part 23 can likewise be extended from one or the other of the extreme prongs 2D and 22 and end in a whistle shape as shown at 24, for the purpose of diminishing the resistance it could offer to the sliding.

Manifestly variations other than those shown may be resorted to and parts or features used without others within the scope of the appended claims.

Having now fully described our invention, we claim:

1. In fittings for fixing and the like to skis and comprising at least one pair of cooperating members capable of securely connecting the ski and skin into a composite whole, wherein the one or first member is fixed to the bottom of the ski and the other or second member secured to the skin, the features consisting in that the first member fixed to the ski is elongated longitudinally of said ski and has prongs at the ends extending into the bottom of the ski, there being longitudinally disposed notches formed in said ends and prongs at their mutual junctions, and in that the second member secured to the skin includes an integral pair of opposed elongated jaws capable of partly enveloping and directly gripping the elongated portion of said first member in longitudinally slidable relation therewith.

2. Fittings for skis according to claim 1, wherein the first or elongated member is located in a longitudinal groove in the bottom of the ski, and the jaws of the second member project into said groove when said jaws grip the first member.

3. Fittings for skis according to claim 1, wherein the first member is located in a longitudinal groove in the bottom of the ski, and the second member is actually subdivided into two individual members extending toward each other and each 01' said individual members constituting a jaw, and wherein both jaws project into said groove when said jaws engage the first member.

4. Fittings for skis according to claim 1, wherein the cross section of the elongated portion of the first members is substantially round, so that ie same can be directly gripped by the jaws of the second member.
