3 Claims. (Cl. 280- -11,.13)

The present invention'relates generally to new and useful improvements in skis, and has for its primary object to provide, in a manner as hereinafter set forth, an attachment comprising a novel construction and arrangement for increasing traction and preventing slipping in any direction.

Another very important object of the invention is to provide a traction and anti-slipping attachment of the aforementioned character which may be applied to a conventional ski without the necessity of making material structural alterations therein.

Still another very important object of the invention is to provide a ski attachment of the character described which may be expeditiously mounted on the ski and removed therefrom.

Otherobjects of the invention are to provide a ski attachment of the character set forth which will be comparatively simple in construction, strong, durable, highly eflicient and reliable in use, compact, light in weight, and which may be manufactured at low cost.

All of the foregoing and still further objects and advantages of the invention will become apparent from a study of the following specification, taken in connection with theaccompanying drawings wherein like characters of reference designate corresponding parts throughout the several views, and wherein:

Figure 1 is a View in side elevation of a ski equipped with an attachment constructed in accordance with the present invention.

Figure 2 is a top plan view thereof.

Figue 3 is a bottom plan view of removable portion of the device.

Figure 4 is a cross-sectional view, taken substantially on the line 4-4 of Figure 2.

Figure 5 is a fragmentary view in vertical longitudinal section, showing the means for securing the forward end of the traction device to the ski.

Referring now to the drawings in detail, it will be seen that the embodiment of the invention which has been illustrated comprises a metallic traction unit which is designated generally by reference numeral I. The traction unit I is adapted to be removably mounted beneath a conventional ski 2 in spaced relation to the ends thereof. As illustrated to advantage in Figure 3 of the drawings, the unit I includes an intermediate section 3 having hingedly connected thereto comparatively long front and

rear sections

4 and 5, respectively.

The intermediate section 3 comprises a pair of longitudinal metallic side bars 6 having fixed therebetween a traction member or cleat in the form of a frame I. The end portions of the side bars 6 are provided, in their upper portions, with notches or recesses 8, the purpose of which will be presently set forth. The upper portions of the side bars 6 receive the ski 2 therebetween.

The

sections

4 and 5 include longitudinal side bars 9 which also receive between the r upper portions the ski 2. Flanges ID on the inner faces of the bars 9 are engageable beneath the ski 2. The bars 9 are pivotally connected at their inner ends, as at I l, to the end portions of the bars 5.

The bars 9 terminate, at their outer ends, in upwardly and reversely curved'hooks l2, the purpose of which will also be presently set forth. Metallic traction members in the form of skeleton frames l3 are fixed between the bars 9 below the flanges Ill. The members l3 are pivotally connected at their inner ends, as at hi, to the ends of member 1. The pivots H and M are aligned, whereby the

sections

4 and 5 may swing on the intermediate section 3. Flanges l5 are struck outwardly from the inner end portions of the bars 9. The flanges l5 are engageable on the adjacent end portions of the bars 6 for positively preventing the

sections

4 and 5 from being swung upwardly beyond a position in longitudinal alignment with the intermediate section 4. The recesses or notches 8 in the bars 6 accommodate the stop members 15.

A substantially U-shaped bracket is is mounted on the rear portion of the ski 2. Screws H secure the bracket I6 in position. The bracket I6 is further provided with depending teeth or prongs l8 which are embedded in the ski 2. A rod I9 i mounted transversely on the bracket l6, said rod including headed ends 2!] which project beyond the longitudinal edges of the ski 2. The end portions of the rod l9 are engageable in the hooks l2 of the section 5 for detachably securing the rear end of the unit l in position beneath the ski 2.

A substantially U-shaped bracket 2! is mounted on the forward portion of the ski 2 and secured in position by means including screws 22. The bracket 2| is also provided with teeth or prongs 23 which are embedded in the ski 2. The upstanding fianges or side walls 24 of the bracket 2| have formed therein longitudinal slots 25. A substantially Y-shaped lever 26 is mounted for compound movement on the bracket 2| through the medium of links 21. The links 21, it will be noted, have one end pivotally connected to the flanges 24 of the bracket 2i and their other ends pivotally connected to the free end portions of the arms 28 of the lever 26. A rod 29, similar to the rod I9, extends between the free end portions of the lever arms 28 forwardly of the links 21, said rod 29 being operable in the slots 25 and having its headed ends projecting beyond the longitudinal sides of the ski 2. The end portions of the rod 29 are engageable in the hooks I2 of the section 4 for tightening the unit I beneath the ski 2 and for detachably seeming the forward end of said unit to said ski. A plate 30 is fixed on the free end portion of the lever 26 to facilitate actu-, ating said lever. A resilient clip 3| on the ski 2 releasably secures the lever 26 in lowered position.

It is thought that the manner in which the device functions will be readily apparent from a consideration of the foregoing. Briefly, the unit I is laid out flat on a suitable support and the ski 2 is placed longitudinally thereon between the upper portions of the pairs of

bars

6 and 9. The rod I9 is engaged in the hooks I2 of the rear section 5. The lever 26 is then swung downwardly past dead center on the ski 2 in a manner to move the rod 29 forwardly into engagement with the hooks I2 of the front section 4. Thus, the unit I is held taut beneath the ski and the forward end of said unit is firmly but detachably connected to said ski. Of course, to remove the device, the foregoing operation is substantially reversed. When not in use, the unit I may be conveniently folded and carried over the shoulder.

It is believed. that the many advantages of a ski attachment constructed in accordance with the present invention will be readily understood, and although a preferred embodiment of the device is as illustrated and described, it is to be understood that changes in the details of construction and in the combination and arrangement of parts may be resorted to which will fall within the scope of the invention as claimed.

What is claimed is: 1. A ski attachment of the character described comprising an elongated traction unit engageable longitudinally beneath a ski, said unit comprising a plurality of hingedly connected sections, upwardly and reversely curved hooks on the outer ends of the outer sections, a transverse rod on the ski engageable with the hooks on on end of the unit, a lever mounted for swinging movement on the ski, and a rod on said lever engageable with the hooks on the other end of the unit, said rods constituting means for detachably securing the unit in position beneath the ski.

, 2. A ski attachment of the character described comprising an elongated traction unit adapted to be mounted longitudinally beneath a ski, c0- acting means on one end of the unit and the ski for detachably securing said one end of said unit to said ski, hooks on the other end of the unit, a bracket mounted on the ski and including upstanding flanges having longitudinal slots therein, links pivotally mounted on said flanges, a substantially Y-shaped lever pivotally mounted on said links, and a transverse rod mounted on the lever and operable in the slots, said rod being engageable in the hooks for releasably securing said other end of the traction unit to the ski.

3. A ski'attachment of the character described comprising a traction unit adapted to be mounted beneath a ski, said unit including a plurality of hingedly connected sections, said sections comprising pivotally connected side bars and further comprising pivotally connected traction members between the side bars, said unit still further including inwardly extending flanges on certain of the side bars engageable beneath the ski, and means for detachably securing the ends of the unit to the ski.
