R m B a d MW e H w PARALLEL SKI TRAINER AND LEG CONDITIONER The instant invention has been specifically designed to permit a skier to practice parallel turns at home using his own boots and skis and under conditions that effectively simulate actual snow and skiing conditions.

The regular use of the device of the instant invention ability to maintain his skis parallel to each other, particularly through each and every turn. To the extent that his skis are permitted to separate or are permitted to be forwardly convergent, his achievement toward parallelism is downgraded. There are several independent motions which must become matters of musclememory to properlyexecute this turn.

When it is desired to execute a right turn in parallel skiing, the skier pumps his legs so as to lower his body, raise his body and then lower his body again. It is this body movement whichunweights the skis, particularly at the rear ends thereof so that the major contact of the skis with the snow surface is at the forward or tip end of the skis. This permits the rear ends of the'skis to be moved laterally to the left. As the rear ends of the skis are shifted laterally to the left, the skis are rotated slightly about their longitudinal axes so as to raise the left edge portions thereof and the right hand ski is shifted slightly forward of the left ski. These basic maneuvers are carried out repeatedly during parallel skiing and can be accurately reproduced by utilizing theins'tant invention thereby enabling a skier to maintain himself in optimum condition for executing such moves when actually skiing, even during the summer months when no'snow is available.

The main object of this invention is-to provide a ski training apparatus which will enable beginning, intermediate and expert skiersto practice parallel skiing arid-to maintain themselves in propercondition for skiing should there be an extended intervalbetween actual-skiing sessions.

Another object of this invention, in accordance with the immediatelypreceding object, is to provide a training apparatus which may be utilized to exercise substantially all of the muscles which are used in parallel skiing. Another important object of this invention is to provide a ski training apparatus enabling a skier to practice parallel turns while actually wearing his ownski boots and skis.

Still another important object of this invention is to provide a training device apparatus in accordance with the preceding objects and operable to simulate parallel skiing turns in a manner such that resistance to lateral shiftingof the rear ends of the unloaded skis is afforded.

A final object of this invention to be specifically enumerated herein is to provide a ski training apparatus in accordance with the preceding objects which will conform to conventional forms of manufacture, be of simple construction and easy to use so as to provide a device that will be economically feasible, long lasting and relatively trouble-free in operation.

These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had i to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:

FIG. 1 is a top plan view of the ski training apparatus of the instant invention;

FIG. 2 is a vertical sectional view taken substantially upon the plane indicated by the section line 2-2 of FIG. 1;

FIG. 3 is a rear elevational view of the ski training apparatus;

FIG. 4 is an enlarged fragmentary transverse vertical sectional view taken substantially upon the plane indicated by the section line 44 of FIG. 1;

FIG. 5 is a fragmentary longitudinal vertical sectional view taken substantially upon the plane indicated by the section line 55 of FIG. 4;

FIG. 6 is a fragmentary side elevational view of one of the rear adjustable length vertical brace members;

FIG. 7 is a fragmentary sectional view illustrating the manner in which the ends of the resilient straps are anchored to the forwardly convergent side rails of the apparatus; v 6

FIGS. 8 and 9 are fragmentary top plan views illustrating the positions in which the associated skis are disposed when right and left hand turns, respectively, are being simulated; and

FIGS. 10 and 11 are fragmentary sectional views illustrating the relative positions of the front ski supports of FIGS. 8 and 9.

Referring now more specifically to the drawings, the numeral 10 generally designates the ski trainer of the instant invention. The trainer ltlincludes a pair'of generally parallel horizontal front and

rear support members

12 and 14. The front support member 12 is appreciably shorter than the rear support member 14 and corresponding ends of the

support members

12 and 14 are interconnected by means of a pair of inverted U- shaped

members

16 and 18. The U-shaped member 16 includes a pair of short and

long legs

20 and 22 inter connected by means of an integral bightportion into whose opposite ends the upper ends of the legs20 and 22 smoothly curve. The U-shaped member 18 includes a pair of

similar legs

26 and 28 interconnected by means of an integral bight portion 30 and it may be seen that the

legs

20 and 26 are substantially vertical and have their lower ends received in

upstanding bores

32 and 34 formed in opposite ends of the support member 12. The lower ends of the

legs

20 and 26 maybe secured in the

bores

32 and 34, if desired.

The

legs

22 and 28 are upwardly divergent, although disposed in the same vertical plane, and the lower ends of the

legs

22 and 28 are received in similar but upwardly divergent bores 36 and 38 formed in opposite end portions of the support member 14.

The bight portion 24 is provided with a plurality 0 vertical bores 40 spaced longitudinally therealong and the bight portion 30 is provided with a plurality of similar bores 42 spaced longitudinally therealong.

' an integral bight portion 54 is secured between the upper ends of the

legs

20 and 26. The upper ends of the 1

legs

48 and 52 include oppositely outwardly directed

end portions

50 and 52 which are secured through the upper ends of the

legs

20 and 26 by means of suitable threaded fasteners 56. The bight portion 54 defines a pair of side by side generally

semi-cylindrical cradles

58 and 60 and each of the cradles supports a semicylindrical follower 61 therefrom. Each of the followers 61 includes a diametric brace 62 through which a clamp screw 64 is threadedly engaged as well as an underlying generally U-shaped bail 66 through which the corresponding cradles or saddles extend. Accordingly, each of the followers 61 is shiftable between the extreme right hand and left hand positions thereof illustrated in phantom lines in FIG. of the drawings and may be oscillated between the oppositely inclined positions thereof illustrated in FIGS. and 11 of the drawings.

A pair of elongated

flexible strap members

68 and 70 are provided and extend between pairs of corresponding locations spaced along the

bight portions

24 and 30. The

strap members

68 and 70 are elastic and each has a plurality of longitudinally spaced transversely extending bores 72 formed through its opposite ends. An anchor pin 74 is passed through a selected bore 72 in each end of each strap member and the ends of each pin 74 are bent as at 76. Each end of each

strap member

68 and 70 is provided with a pair of anchor rings 78 having corresponding ends looped over the bent ends of the associated anchor pin 74 and the rings 78 areslidably mounted on the corresponding bight portion. Further, a pair of cotter pins 80 defining abutments are secured through two pairs of bores 40 and 42 in each of the bight portions 24 and outwardly of each pair of rings 78 whereby shifting of each pair of rings 78 longitudinally of the corresponding bight portion is prevented. Of course, the

support members

68 and 70 may be adjusted laterally relative to each other and longitudinally of the

corresponding bight portions

24 and 30.

In operation, a person using the ski trainer 10 will first support his

skis

82 and 84 on the ski trainer 10 in the manner illustrated in FIGS. 1, 2 and 4 of the drawings with the forward ends of the

skis

82 and 84, just rearward of the tips thereof, clamped in the followers 61. Then, the person desiring to use the trainer will place his feet'upon which he is wearing ski boots in the bindings 86 of the

skis

82 and 84. Then, after the user of the trainer has assumed a standing position and has equipped himself with a pair of ski poles, the user will then push downwardly on and then immediately thereafter lift his feet without applying upward pressure on the forward ends of the

skis

82 and 84 so as to unload the rear ends of the skis. At this point the rear ends of the skis may be shifted laterally as in a parallel turn. Of course, as the rear ends of the skis are shifted laterally in one direction, the skis are rotated about their longitudinal axes in the other direction and the ski on the side to which the skis are rotated is advanced relative to the opposite ski. This maneuver is repeated while swinging the rear ends of the skis to alternate sides.

Although the strap members 68 and are elastic, they are sufficiently strong in resisting elongation so as limit the amount of vertical travel of the rear ends of the skis required to unload" the rear ends of the skis. The tension of the support members or

strap members

68 and 70 may be adjusted according to the weight of the user of the trainer l0 merely by shifting the anchor pins 74 longitudinally of the

strap members

68 and 70. In addition, shifting of the

strap members

68 and 70 longitudinally of the

bight portions

24 and 30 will also have the effect of varying the deflection of the strap members 68 and 70-according to a given load on the

skis

82 and 84.

Through repeated use of the trainer 10 the user thereof may strengthen by exercise substantially all of the muscles utilized in parallel skiing. Further, he may practice turns in parallel skiing with a high degree of simulation of actual skiing conditions and he may also practice in using his ski poles in parallel ski turning.

The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope of the invention as claimed.
