Description:

This invention relates to ski exercising devices.

One object of the invention is to provide a device of the character described whereby all the motions of an expert skier may be practised on a relatively simple, inexpensive and highly compact structure.

Another object of the invention is to provide a device of the nature set forth whereby there may be conveniently practised the right and left turns which are executed by a skier by momentum caused by a rapid twist of the torso.

Another object of the invention is to furnish a device of the class alluded to having improved means whereby an operator may exercise the motions performed in a downward movement with the skis downwardly forwardly inclined and with the body correspondingly tilted with the weight thrown forward.

Another object of the invention is to construct a device of the type mentioned wherein a person may perform movements corresponding to those executed in skiing, wherein the operator may exert intermittent pressure on the heels with an accompanying bending of his knees to thus effect a rapid up and down movement.

Another object of the invention is the provision of a device as hereinafter described having improved means whereby a certain skiing motion is simulated as where the forwardly tilted body of the operator executes a rapid forward move- :;0o ment.

A further object of the invention is to furnish a device having improved means for effecting two or more of the various movements referred to, and whereby the operator may rapidly shift from one to the other of said movements, or stop or slow down a right or left turn, or utilize a ski pole for a related purpose.

Another object of the invention is to provide such device wherein the operator may manipulate foot holding members to slow down or stop his motion down an inclined ramp.

Still another object of the invention is to provide such a device wherein ski poles of improved construction and arrangement are adapted for use to control certain movements as, for example, to slow down or stop the movement down an inclined ramp.

Other objects and advantages of the invention will become apparent as the specification proceeds.

With the aforesaid objects in view, the invention consists in the novel combinations and arrangements of parts hereinafter described in their preferred embodiments, pointed out in the subjoined claims, and illustrated in the annexed drawing, wherein like parts are designated by the same reference characters throughout the several views.

The advantages of the invention as here outlined are best realized when all of its features and instrumentalities are combined in one and the same structure, but, useful devices may be produced embodying less than the whole.

It will be obvious to those skilled in the art to which the invention appertains, that the same may be incorporated in several different constructions. The accompanying drawing, therefore, is submitted merely as showing the preferred exemplification of the invention.

Referring in detail to the drawing, 15 denotes a device embodying the invention. The same may of course be used for exercising one's body including the muscles of the shoulders, torso, and those at the knees, ankles, and feet; but particularly, the device is intended for ski exercising and its utility is best exemplified in that regard. This device 15 may comprise a base member IS on which is mounted a fixed ramp 17. Preferably this ramp is in the form of a curve or arc extending through any suitable angle and is of varying elevation, being desirably upwardly inclined from its ends so that its central region is uppermost. As herein shown, the ramp 17 may comprise a left hand section 18 and a right hand section 19 which are separated from each other by an opening 20 for a purpose hereinafter described.

At some point in relation to the inclined ramp, preferably adjacent to the center thereof, the base 16 may carry means 21 for mounting the forward portions of a pair of foot members or skis 22 for lateral movement, with the rear end portions of the foot members 22 slidably resting upon the top surface of the ramp 17 so that right and left hand motions may be executed along the respective downward inclines 18 and 19.

Preferably the means 21 may also provide for a downward forward tilting of the foot members 22 and may further permit either or both of these foot members to be laterally tilted to present a side edge for gripping an inclined member 18 or 19 with increased friction.

The means 21 may comprise a pin or guide 23 fixed to the base 10. Around this pin 23 extends an expansion coil spring 24. Resting on said expansion coil spring is a bar or lever 25 having an opening receiving the pin 23. Accordingly this lever forms two arms of equal length and may be swung about the pin 23 in a horizontal plane.

Each arm of the lever 25 may have a vertical slot or opening 26 for receiving a cam-like member or disk 21. The latter may have a central pin 28 which may extend into opposed lateral slots 29 formed in each arm of the lever 25. Thus each member 27 may be like a wheel mounted on an axle, the latter being floating, since the pin 28 is slidable along the slots 29. Rigidly connected to each member 27 is a radial upstanding pin 30 which is received in a slot 31 extending along the length of the forward portion of a foot member 22. Accordingly each foot member 22 may bear directly upon its cam or disk member 27 for a lateral rocking motion, the member 27 executing a corresponding angular movement about its pin 28, and, furthermore, each member 22 may also move longitudinally with the pin 30 serving as a guide for the slotted portions at 31.

For automatically retracting the foot members 22 so as to move them rearward, I provide the individual tension coil springs 32 connected to the toe portions of the foot members and to the respective arms of the lever 25.

At the portion of the ramp IT which is of the maximum elevation, I provide means to facilitate a rapid upward and downward movement of the rear end portions of the foot members. Such means may be variously actuated. A very simple construction may consist in the provision of a U-shaped crank 33 carrying a roller 34 disposed within the opening 20, the upper surface of the roller 34 being preferably substantially continuous with the adjacent surface of the ramp 17.

The crank member 33 may have trunnions 35 journaled in brackets 36, 37 which are fixed to the base 16 and also to the ramp sections 18, 19 for supporting the latter. One of the trunnions 35 carries a pinion 38 which engages a gear 39 on a shaft 40 journaled in the bracket 36.

Mounted on said shaft 40 is a fly wheel 41. For rejeasably locking the crank member 33, the other of the trunnions 35 may carry suitable locking means such as an eye 42 in a set screw 43 which is removably engaged in an opening in the bracket 37. As indicated in dotted lines in Fig. 3, the foot members 22 may rest upon the roller S4, and the opening 20 is sufficient in extent to permit the foot members to oscillate up and down therein while resting on the roller 34.

For controlling lateral movement of the foot memTbers 22 down the inclined ramp 17, various means may be provided such as a strip, of frictiopal or rubber-like material 44 set into a foot member- 22 qdjacent a longitudinal edge thereof.

These strips 44 are in confronting relation to each other in the different foot members as shown in Fig. 1 and are operated by tilting the left or right foot member according as the movement is down the left or right incline 18 or 19, to thus present a strip 44 as a gripping edge for the ramp surface. Additional control means may include the ski poles 45 jointed to the respective foot members 22. Each pole may be of angle form, comprising an upright portion 46 and a trunnion 47, the latter journaled in a bearing 48 secured to an outer edge portion of the respective foot member 22. Eccentrically connected to the trunnion 41 is a shoe 49 adapted to frictionally grip the surface of the ramp when the ski pole is swung in an outward direction. Accordingly the left or the right ski pole is thus operated, depending upon whether the operator is moving down the left or right incline. Thus each ski pole may be operated to retard or stop the movement of the operator down an inclined ramp in addition to such action afforded by the strip members 44.

To afford a high degree of flexibility handles 50 are connected to the pole bars 46 by rings 51 for a universal movement of the handles.

Any suitable means such as shoes or other holding devices may be connected to the foot members 22 to reliably hold the feet of the operator.

For example, at the rear end of each foot member there may be a rest or support 52 of arcuate form to fit around the rear end of a shoe, and a strap 53 may be provided to engage over the instep of the foot. For the purpose of reducing friction in the movement of the foot members along the ramp, the former may have slot openings 54 to receive rollers 55 arranged so that they will not interfere with the foot of the operator.

The operation of the device will now be briefly described. Assume that the roller 34 is locked in its uppermost position as by means of the long stud 43. The operator, whose feet are secured to the ski or foot members 22 may stand in position with the latter resting upon the roller 34 as shown in dotted lines in Fig. 3. The operator may also grip the handles 50 of the ski poles 45.

Now by a rapid twist of his body to the right or left, the members 22 are caused to slide down the ramp members 19 or 18 respectively, with the rollers 55 reducing friction to a minimum so that a rapid motion is attainable. While this is occurring, one of the foot members 22 may be somewhat in advance of the other since the lever 25 is in free pivotal relation to the foot members; thus the idiosyncrasies of the individual skier are accommodated. If the operator wishes to retard or stop his movement, he twists his ankle to laterally tilt the proper foot member 22 to present the frictional gripping portion 44 to the surface of the ramp. If he requires additional power to retard or stop his movement, he may swing the proper pole bar 45 in an outward direction so that the.eccentric shoe 49 also grips the surface of the ramp. To return to the top of the ramp, the operator may execute a springing motion combined with a twisting of his torso or he may merely side step, thus bringing the members 22 back to initial position.

While executing the lateral movement downward along the ramp, the operator may press forward with his body correspondingly tilted to depress the front portions of the foot members 22 against the force of the spring 24. This may be 75: readily effected because in general the lever 25 tends to swing with the foot members 22. Of course this forward downward tilting of the foot members may also be caused when the operator is in initial position above the roller 34. Furthermore, it will be perceived that the lateral tilting of the foot members, as by the elements 44 or 49, may be caused in both the downwardly tilted and in the normal upright positions of the foot members 22.

If a rapid forward motion is desired, the operator may cause a corresponding momentum of his body with the foot members 22 moving forward against the tension of the coil springs 32, the pins 30 riding in the slots 31. In fact, this forward motion may be effected while there is a lateral downward movement along the ramp, and while the operator is preparing to stop such lateral downward movement by one or the other of the frictional gripping portions 44 and 49.

The tension coil springs 32 are intended to be sufficiently strong to retract the foot members 22 to normal position.

It will thus be seen that a plurality of motions may be executed almost simultaneously and in different variations. Moreover, one of the foot members may be depressed below the other, with the lever 25 tilting due to loose journaling thereof on the pin 23. To the contrary, the lever 25 may be regarded as tightly frictionally engaging said pin 23 for a braking action to require additional control by the foot members 22.

By removing the stop element 43, the operator may perform a rapid upward and downward oscillatory motion under the weight of his body, with the foot members 22 actuating the roller 34 which will thus impart a suitable momentum to the fly wheel 41. Thus the operator, leaning forward and with knees bent, may simulate the motion which may be quite like that of an undulating snow surface. At the instant that he is in an uppermost position, the operator may slide off the roller 34 and on to one of the ramp members 18 or 19. He may readily return back on to the roller 34 by providing suitable means to assure that the roller will return to its uppermost position. Such means may consist in a lateral arm or crank portion 56 on the eye 42, carrying a freely rotatable collar 57 connected by a tension coil spring 58 to the base 16. It will be understood that in place of the fly wheel 41 and its drive, a motor or other suitable source of power may be substituted, although I prefer to utilize the energy of the operator himself to execute this oscillatory motion.

While the oscillatory motion with the aid of the crank 33 is occurring, the operator may also perform a forward motion against the tension of the coil spring 32, and the latter may readily retract the foot members 22 to initial position, especially while they are at the lowermost point of their oscillatory path on the roller 34.

It will thus be seen that by the provision of a rather simple and highly compact device, a multitude of motions and combinations of motions with their variations may be performed simultaneously or in rapid succession, to fully realize the objects of the invention in a wholly practical manner.
