BACKGROUND OF THE INVENTION This invention relates to skis and, more particularly,
to skis for usewith snowmobiles and the like for steering the same.
One area of use of the present invention is with snowsurface of the ice or snow, damage to the ski or snowmobile or even an accident can occur. Even very small obstructions if encountered repeatedly can wear down the blade prematurely.

It is a further object of the present invention to provide such a steering ski wherein the keel member has an improved gripping action with the snow or ice surface.
The present invention provides a ski for snowmobiles and the like comprising a ski runner and a keel member resiliently mounted at one end to the runner and pivotally connected at the other end to the runner. The
' keel member blade edge normally is below the under surface of the runner, and the keel member is moved BRIEF DESCRIPTION OF THE DRAWING FIGURES FIG. 1 is afragmentary elevational view of a steering ski according to the present invention as it would appear in use with a snowmobile;

DETAILED DESCRIPTION OF THE ILLUSTRATED I EMBODIMENT FIG. l'shows a steering ski, designated generally at 10, as it would appear in use with a snowmobile, a pormobiles, although the principles of the invention can be m tion of the body of which is indicated at 11. In particular, ski 10 is positioned and attached beneath snowmobile 11, and a generally curved connecting member 12 in the form'of a spring is connected at opposite ends thereof to longitudinally spaced points on ski 10. One
end of member 12 is fixedly connected through a bracket 13 to ski l0, and the other end is slidably connected to ski 10 by a strap-like member 14. Member 12, in turn, is connected to a member shown generally at ll mounted on the under side of snowmobile body 11, and operatively connected to the steering wheel of the snowmobile. The construction and operation of member 12, and the steering arrangement connected to member 15, form no part of the present invention but are believed to be well known to those skilled in the art so that a detailed description thereof is deemed to be unnecessary. In addition, an identical steering ski and connecting arrangement would be provided alongside and parallel to the steering ski shown at 10 in FIG. 1.
Steering ski 10 according to the present invention comprises a ski runner 20 which in this illustration includes an upturned portion 21 at one end thereof. When ski 10 is attached to the snowmobile, upturned end 21 is disposed toward the front end thereof. First and second longitudinally extending slots 23 and 24, respectively, are provided in runner 20 as shown in FIG. 2. Slots 23, 24 are contiguous in length, are mutually parallel with each other and with the longitudinal axis of runner 20, and spaced apart a suitable distance measured in a direction perpendicular to the'axis of runner 20. In addition, slots 23, 24 are located in the region of runner 20 substantially in the middle relative to the ends thereof. Slots 23, 24 each are of a length less than half the length of runner 20.
Steering ski 10 according to the present invention further comprises a keel member 25 including a base portion, as shown in FIG. 4, and a pair of spaced apart, depending blade members 27 and 28. When keel member 25 is in assembled position, the base is disposed in a generally horizontal plane, and, blade members 27, 28 each are disposed in a corresponding vertical plane and each extends atsubstantially a right angle to the base. Keel member 25, in addition, is positioned so that blades 27,28 extend through and are vertically. movable in slots 23 and 24, respectively. In
preferred form, blade 27 is provided with an edge 29 which is arcuate or curved and, similarly, blade 28 is provided with an arcuate or curved edge 30.
Steering ski 10 according to the present invention further comprises means connected to runner 20 and to keel member 25 for pivotally connecting keel 25 at one end to runner 20 and for resiliently connecting keel 25 at the other end to runner 20. Referring to FIGS. 1 and 3, one end of keel member 25 is pivotally connected'to runner 20 by means comprising a pair of generally L- shaped bracket members 35, 26. Bracket members 35, 26 are secured to the upper surface of runner 20 by means such as screws 37, and are positioned near the ends of slots 23, 24 nearest upturned end 21 of runner 20. In addition, brackets 35, 36 are located in alignment with each other along a line perpendicular to the longitudinal axis of runner 20, and are spaced apart a sufficient distance so that slots 23, 24 are located between the vertical or upstanding portions of brackets 35, 36. A pin or shaft member 38 extends through projecting portions of keel member 25 coplanar with blade members 27, 28 at one end of keel 25 and through the vertical or upstanding portions of brackets 35, 36. Shaft 38 is disposed so that the axis thereof is perpen- Accordingly, the present invention accomplishes its intended objects. While a single specific embodiment of the present invention has been described in detail, this has been done by way of illustration without dicular to longitudinal axis of member 20. As a result, 5 thought oflirnitation.
Keel 25 is resiliently connected to runner 20 by means including a generally chanel-shaped member 40 having a base portion 41, a pair of legs 42, 43 each extending from base 41 at substantially a right angle thereto, and a pair of arm or tab members 44, 45 which extend outwardly and in opposite directions and at substantially right angles to legs 42, 43. The distance between legs 42 and 43 is greater than the distance between the corresponding outer edges of slots 23, 24. Channel member 40 is assembled on runner 20 so that base 41 lies in a generally horizontal plane and so that member 40 is positioned over the end of keel 25.'
Ski according to the present invention is assembled under a snowmobile as shown in FIG. I, it being noted that two skis are so assembled as previously described. In particular, the end of keel 25 which is pivotally mounted to runner is nearest what would be the front end of the snowmobile. Accordingly, the end of keel which is resiliently connected or mounted to runner 20 is located nearest the rear end of the snowmobile. In addition, keel member 25, and ac-, cordingly blades 27, 28, is located in the central or middle region of runner 20 and has a total length less'than one-half the length of runner 20. According to .the present illustration the length of keel 25 is approximately one third that of the runner 20.
In operation, as the snowmobile travels over the snow or ice surface, blades 27, 29 normally extend below the under surface or operative surface of runner 20 to enhance the steering provided by ski l0.- Blades 27, 29 are always under tension to allow ski 10 to give a positive steering action at all times. The fact that keel 25 is provided with spaced apart, parallel depending blades 27, 28 increases the steering capability of ski 10. In addition, this is accomplished with blades which are relatively shorter in length than many heretofore available.
As the snowmobile travels along the snow or ice surface with blades 27, 29 fully extended below the surface of runner 20, if a rock or similar obstruction is encountered, it forces keel 25 upwardly so that the edges 29 and 30 of blades 27 and 28, respectively, are moved to a position flush with the under surface of runner 20. This provides at least two desirable results. In the first place the impact. is cushioned thereby reducing or eliminating any damage to the snowmobile or discomfort or injury to the rider. Secondly, the wear on blades 27, 28 is reduced.
