sq 2o 36 32 BACKGROUND or run lNvEN'noN MouN'r roe -thing more challenging to'the'm.

In water skiing, a major shift in the-sport has been'to master the art of skiingover the water on a single ski. This is because skiing on the water with two skis preaents less and less of a challenge, especially to skilled water skiers. The need for similar stmcture to'perrnit more advanced snow skiers to increase theirskills now exists and the present invention was conceived for this particular purpose, mainly to provide apparatus allowing a snow skier to ski on only one ski to thereby provide heightened enjoyment while increasing his'skills.

. SUMMARY OF THE INVENTION The present invention is directed to apparatus for attachment to a single snow ski and provided with means thereon for releasably mounting a pair of ski boots in a manner to allow the ski boots to shift relative to each other and'to the ski to which the apparatus is attached. To this end, the apparatus includes a mount having a base provided with post means 'extending downwardly therefrom for attachment to the single ski. The base has two. side-by-side, generally parallel sections; t-lch section having a pair offront and rear lnclined slots which shiftably receive pins so that. when respective boot mounting members are coupled with respective pins, the boot mounting members can shift longitudinally of the base sections and carry bootseither forward or rearwardly depending upon'the direction of movement of the members. Bach mounting member has binding means on the flat upper surface thereof for releasably attaching a ski boot thereto. Also, a link interconnects the two mounting members andis pivotally coupled intermediate its ends to the base to assure that, when one member moves in one direction, the other member will move in the opposite direction. This is essentially to allow the skier using the apparatus to make turns from straight, forward travel.

The entire structure of the present invention can be made of any suitable material, such as metal, plastic or the like. Also, certain parts can be of metal while other parts can be of plastic. Conventional ski bindings can be utilized to minimize the expense of producing and using the apparatus. It can be quickly assembled to a single ski and removed therefrom and can he carried to a ski 'slope and used at any time.

The primary object of this invention is to provide an improved mount for a single aki wherein the mount includes means for securing a pair'ofskl boots to the ski for limited shifting movement longitudinally of the ski so that a skier can move over the snow on a single ski and can make turns without the need for a second ski as is conventionally required.

Another object of this invention is to provide an improved apparatus of the type described wherein the mount has a base for attachment to the single ski and a pair of skimountingm'embers shiftably mounted on side-by-side relationship on the base and interconnected'with each other by a link so that when a pair of ski boots are attached to the mounting members, the skier can move in a forward direction over snowy terrain or can make turns from straight. forward movement, all of which can occur without the need for a second ski.

Still another object of this invention is to provide a ski'boot mount of the aforesaid character wherein the mount can be of any suitable material and can neither be permanently or releasably connected to a standard ski so as to render the same adaptable for wide variety of uses.

Further objects of this invention will become apparcut as the following specification progresses, reference being had to the accompanying drawings for an illustration of an embodiment of the invention.

FIG. 5'is a cross-sectional view taken along line 5-5 of FIG. 4, and

, FIG. 6 ii a crosssectional view taken along line 6-6 of FIG. I.

The boot mount which is the subject of the present invention is broadly denoted by the numeral [0 and includes a base 12, a pair of

boot mounting members

14 and 16, a pair of pins, 18 for shiftably mounting each of the boot members, respectively, on base 12, and a pair of

posts

20 and 22 for coupling base 12 to a single ski 24 at the upper surface 26 thereof. FIG. 1 shows the way in which each of

posts

20 and 22 are coupled by screws 28 to ski 24. These screws extend through flanges at the lower end of

posts

20 and 22.

FIGS. 4 and 5 show the way in which

posts

20 and 22 are coupledto ski 24 when the same has conventional bindings on the upper surface 26 thereof, such bindings including a front element 30 and a rear element 32. To this end,

posts

20 and 22 have forward and rearward projecting portions or

flanges

34 and 36, respectively, for releasable connection to binding elements 30 and 32'. As shown in FIG. 4, 'projection 34 is secured by a machine screw 38 to the bottom face of post 20. Similarly, projection 36 can be secured by machine screw to the bottom face of post 22. Base 12 has a cross-section as shown in FIG. 5. To this end, base 12 has two inverted U-shaped, sideby- 'side sections 40 and '42 which have an integral web 44 therebetween at the lower portion thereof and extending the length thereof.

Posts

20 and 22 are secured to web 44 in any suitable manner, such as by machine screws '46 (FIG. I) to web 44.

Each of the

sections

40 and 42 has a flat upper surface 48 which slopes downwardly and rearwardly as rear post 22 is approached from forward post 20. Each of the

sections

40 and 42 has a bight'Sll provided with a pair of

inclined slots

52 and 54 therethrough, the slots being aligned with each other as shown in FIG. 1 with one of the slots being adjacent to and above post 20 and the other slot being adjacent to and above post 22.

3 These slots are. adaptcdto receive respective pins 18 so that the pins may move longitudinally of respective slots.

Each 18 has a roller 54 rotatably mounted thereon, each roller bcingof adiamet'e'rwhich is substantially equal to the width of the corresponding slot 52 but slightly less than the same to allow the roller to move in rolling engagement along the lower surface 56 defining the corresponding slot. Each slot 52 in section 40 is aligned with a corresponding slot in section 42. The slots are substantially inclined as shown in FIG. I so that the pins move along inclined paths in a manner to be described.

Boot mounting

members

14 and 16 areprovided for

sections

40 and 42 respectively. Each of the boot mounting members is transversely U-shaped and has a pair of

sides

58 and 60 and a bight 62 integral with

sides

58 and 60. The width of

sides

58 and 60 increases in the manner shown in FIG. 1 as the rear end of mount is Pins [I extend into and through

sides

58 and 60 of respective mounting members 14 as shown in H6. 5. This allows the mounting members to move longitudinally of

respective sections

40 and 42 through limited distances defined by the lengths of

respective slots

52 and 54.

Each of mounting

members

14 and 16 has a flat upper surface 62 as shown in FIGS. 1 and 3. Ski binding means of any suitable construction can be provided on surface 62 to connect aski boot thereto. For purposes of illustration, such binding means includes a front binding element 64 and a rear binding element 66, both of conventional Upper surface 62 is essentially parallel with ski 24.

Members

14 and 16 are piv'otally interconnected by a link 68 (FIGS. 2 and 3) which is pivotally mounted intermediate its ends by a pin 70 rigid to and extending upwardly from web 44 of base 12. A first pin 62 eatends downwardly from side 60 of section 14 as shown in FIG. 3 and into a slot denoted by the numeral 14. One end of link 68 is pivotally mounted on pin 72. Similarly, a second pin 76 extends downwardly and into a slot 78 formed in side 60 of mounting member 16. Link 68 thereby pivotally interconnects members t lv and 16 and assures that, as member 14 moves in one direction, member 16 will move in the opposite direc tion. This is important when the skier using apparatus 10 is making a turn.

In use, mount it) is first placed on a single ski 24 either by a permanent connection of the type shown in FIG. I or by releasable connection of the type shown in FIGS. 4 and 5. The skier using mount 10 then positions hii ski boots on upper surface 62 of mounting

members

14 and 16. The boots are then coupled to mount 10 using the

ski binding elements

64 and 66. With both boots coupled to respective mounting

members

14 and 16, the skier commences to move down a slope or over snowy terrain. During straight, forward movement, the skier positions the boots side-by-side with neither boot ahead of the other. When the boots are so positioned. link 68 is substantially perpendicular to the longitudinal axis of ski 24 and pins 18 are approximately mid way between the ends of respective slots. The skier keeps his boots at these positions as long as continued straight, forward movement is desired.

When it is desired to move, for instance, to the left, the skier moves his left foot forwardly, thereby moving mounting member 16 forwardly along its respective section 42. Because

members

14 and 16 are interconnected by link 68, forward movement of member 16 causes rearward movement of member 14 and the skier automatically leans his weight on his left foot and thereby on member 16. This the ski to turn to the left and to continue the turr'rso long as the left foot is forwardly of the right foot. To return the ski to straight and forward movement, force is exerted down wardly on. the left foot causing member 16 to move once again rearwardly. As this occurs, member 14 moves forwardly and the skier can determine. by feel when the feet are approximately sidcby-side once again, thereby assuring straight, forward movement of the ski. r

To make a right turn, the right foot isurgedforwardly and the left foot is automatically moved because ofthe connection between

members

14 and 16 by link 68. Following the making of the right turn, the right foot is again moved manually and into side-byside relationship to the left foot for continued straightforward movement of the ski.

The inclination of slots 52 and S4 the movements of

members

14 and 16. For instance, to make a lettha'nd turn, the skier could exert a downward force on the right foot, causing member 14 to move rearwardly to thereby in forward movement of member 16. To return from a left turn to straight, forward movement, force is exerted on member 16 downwardly so that rollers 54 corresponding to member 16 will move downwardly and rearwa'rrlly while weight on the right member 14 will be minimized to allow forward movement of the corresponding rollers upwardly in the corresponding slots.

The present invention therefore provides an improved structure .for providing enjoyment and a means to increase the skills of a mow skier who mastered the skills of skiing with two skis. it is also suitable for average-type skiers with a certain amount of practice.
