Abstract
INVENTION APPLICATION
CROSS COUNTRY SKIING MACHINE
SIMULATOR
ABSTRACT
This invention describes a cross country skiing exerciser consisting if a metal frame which contains four tracks on which four carriages slide: two for the trainee's feet and two for his ski poles, all said carriages being interconnected via a flexible steel cable running over a plurality of pulleys in such manner as to simulate cross country skiing.
SPECIFICATION
Medical and fitness authorities agree that the best cardiovascular exercise is cross country skiing. Some of the reasons are:
1. Rapid rise in heart rate and oxygen consumption.
2. More muscles involved than in almost any other sport.
3. Stand up exercise--works some of the largest muscles in the body for greater oxygen consumption.
4. Fluid, natural movements, akin to long stride walking.
5. Less boring, people will exercise longer.
6. Non jarring, far easier on joints and ligaments than jogging or jumping in place.
7. Promotes flexibility of the joints because of the large number of joints being flexed.
The present invention relates to a machine which closely simulates the movements of a cross country skier. The machine can be used indoors to train for cross country skiing in the off-season or to train for cardiovascular (aerobic) fitness and can be used by men and women of all ages.
Most fitness machines presently on the market exercise only one or two muscle groups. For example, bicycle exercises work only on leg muscles.
Rowing machines use primarily the arms and upper thigh muscles (quadriceps). Good aerobic exercise such as jogging or jumping in place are very hard on the joints and can lead to serious injury.
Next to cross country skiing, the best cardiovascular training can be achieved in a cross country skiing simulator such as the one described here.

DESCRlPTIOli OF THE IIIVEIITIO~ - PI~EFERRED Eh~BODI}~ENT
~Fig. 1 ~ ~
The machine consists of a met~l fran~e 1 comprising five tracks on which four carriages slide. The ~arriages are in~erco~nected ~ means of a fle2 :ible, plastic coated steel cable 7 gui~ed over eight idler pulleys 4.
Two ca rriagesJ designa~ed Left Foot Pad ~ and ~ight Foot ~ 3 serYe as supports for ~he kainee's feet,. These ~rriages roll on rollers 9.
The o~er ~ ~rriages, designa~ed Left Pole Carriage 5 and Right Pole Carri~ge 6 ~ide o~ low friction pads 10 and haYe holes into which ski poles 11 can ~e inserted.
A~ the beginni~g of e~ercise~ a~ll four carriages are lined up abre~ at t~e mid po~ition of t~aYel.
OPE~TIOII OF T~ A~IIlIE
The trainee s~eps onto t~e foot pads, and inserts the ski pole ~ps into the pole c3~riage holes. Any ski poles c~n be used: cross country or downhill.
He ~en be~ns 1;4 operate t~e mac~ine: as he slides his left foot fon~rdthe right Ioot slides backward due to the interconnecting ca~le, ~ich also ~ings tbe right slci pole carriage forw~d and the left one rearward. When the end of the stroke is re~ched, ~e operation is fait~fully reYersed, duplicating t~e motions used in cross coun~ry sl~iing.
Great care w~s ta~en to simulate the condi~ons encountered in actual skiing:
a. l~e foot pads moYe on rollers in order to duplica~e the low friction conditions of skis sliding on packed snow.
b. The ski pole carriages slide on fri~tion pads and the trainee has to e~rt a ce~tain amount of force pus~ing downward ~nd re~ward wit~ ~e ski poles. Be~use of sliding friction, t~e force of friction resisting the mo~em~tis dir~dy pro~ional to t~e downward force applied. l~us, the ~ra~ee conkols the amou~t of force ~ be overcome by his mus~les ~in pus~ing ~nd pulling all four c~rriage~) simply ~ ~arying ~e force w~
whic~ ~e leans on ~is poles.
1~5~;7~
Becau~e o~ the fle~ible steel cable which interconnects all four carriage~, the total foroe of friction to be overoome b~y the ~ystem is distributed by the trainee (oonsciolJsly or unconsciously) in wch fashion as to produoe oplimum training. For e~ample, if he wishes to e~erciæ his arms more, he can let his feet glide ~nd he pushes backwards harder with his arm muscles. Or he c~n pre~s downward~ ~ith his arms (but not backwards) and let his legs push and pull the foot pads, to si~nulate wet snow conditions. Hill climbing can be simulated by pre~sing hard with the ski poles bot~ down~vards and backwards.
ALTI;RNAl'E I~lBt)Dl~ (Fig. 3, 4 8~ 5) In this embodiment, the machine is the same ~s described In the preferred embodiment e~oept that pole carriages 5 and 6 are each mounted on four r~ller~ 8. The~e roller~ are ~imilar to tho~e uæd on the foot pad~ eIoept smaller in diameter. The friction devioe is no~v modified so that as ~pring 13 (oentrally guided by means ~ bushing 12) is compres~ed, a progre~sivsly greater foroe is applied to friction pad or pads 10, said friction pad or pads being dependably mounted onto member 14. Thi~
arrangeme~ erfectively 3eparates the t~vo functions: the rollers 8 ~upporting ~nd guiding the pole ~rri~8e~ for ~mooth, rapid movement alld tbe spring loading all~wing a variable friction foroe, proportional to the d~wnward pu~hing effort ~f the ski pole~.

In this embodiment, the machine i8 the same as described }n ~1~BODIM13NT
above eIoept that there i8 no friction devioe at all. The re~istanoe to motion comes from the frictional resistanoe ~ the rollers running on their trac~s; greater resist~moe can be achieved by increasing the speed ol movement, the length of the stride, OF both.

Claims (3)
1. An exercising device used to simulate the motions of cross country skiing and consisting of a rectangular frame with five longitudinal tracks on which four carriages slide, two centrally positioned longer carriages designated as foot pads and serving as supports for the trainnee's feet and rolling on a plurality of rollers each, and the other two shorter, outwardly positioned carriages, one to the right of the foot pads, the other to the left, said shorter carriages being designated as pole carriages and being used as supports for ski poles and gliding on low friction surfaces such as teflon on steel or some other suitable low friction, non-wearing material combinations, all said four carriages being interconnected via a single, flexible, steel cable running over a plurality of pulleys, said pulleys being strategically located so that when the left foot pad moves forward, the right pole carriage moves forward also, while at the same time the right foot pad moves rearward together with the left pole carriage, the purpose of the arrangement being to vary the resistance felt at the said four carriages in direct proportion to the downward force being applied by the trainee on the ski poles.
2. An exercising machine as described in Claim 1 above except that to each of the two aforementioned pole carriages, a plurality of rollers and a centrally guided spring or springs or other resilient member or members are added, the purpose being to separate the two following distinct functions, one function being provided by the said rollers supporting and guiding the said pole carriages whereas the second function being performed by the centrally guided springs or resilient members which, being inserted between the ski poles and the friction surfaces, are employed to provide a more gradual proportionality between the downward travel of the ski poles, as the springs are being depressed and the applied force felt at the friction surfaces, the net result being smoother, less jerky resistance as felt by the trainee at all four carriages.
3. An exercising machine as described in claim 2 above except that no friction device at all is employed, the resistance to motion resulting strictly from the frictional resistance of the rollers running on their tracks, said frictional resistance being controlled over a limited range by varying either the speed of movement or the length of the stride of the trainee's legs, or both.
