FIELD OF ART
This invention relates to an apparatus which sim~ tes the positions required to pelrolm effective downhill skiing. The user fastens into the apparatus into two foot harnesses which form part of the appal~ s. The skis are fixed on entry and then they are freed up to slide back and forth, to rotate side 15 to side, to tilt side hill to side hill and to tilt forward and back. Poles are attached for balance.
PRIOR ART
Cross country ski apparatus are available that provide forward to back sliding motion to ~im~ te cross country skiing.
Downhill ski exercise machines are available that provide side to side sliding action to provide exercise 20 in preparation for skiing and are the closest thing to ski action.
Page# 1 of 11 ~58/~6 ADVANTAGES OF THE INVENTION
This invention replicates the positions and motions of sidehill and downhill tilting that are part of the sport of downhill skiing.
The appalalus may be equipped with actual ski bindings mounted on skis or ski like support means 5 The width of the skis are ~dj~lsted to the width most appropliate for the user. The user enters actual ski bindings mounted on skis or ski like support means.
The app~lus is ideal to be used in prepal ~lion for skiing in conjunction with instructors of skiing and or suppliers of ski equipment.
In addition to the use as a tool for instructors of skiing, the appa,~ s serves as a training m~çhine for 10 strength and flexibility Muscles, tendons and joints specific to the sport of downhill skiing are strçn~h~tled and stretched through their useful range.
In addition to the uses of instructing and training the app~lus serves as a means of ev~ ting ski boots for suitable flexibility and ~ ess required for effective and proficient downhill skiing.
As an important byproduct of all of the above, the use of the ~imlll~tor before skiing and between 15 sessions of skiing will put the user in better condition sport specific and thereby reduce the potential for . .
m~ury when sklmg.
Page#20fll - 213~806 -GENERAL DESCRIPTION OF THE INVENTION
The user fastens into the two foot halllesses which may be actual ski billdillgs O in which case he or she will wear actual downhill ski boots. Figure 1 illustrates the skis and ski bindings option of the .~im~ tor He or she is then ~ttarlled to the app~al-ls which is then at the starting position in the app~aL~Is.
5 Starting position is with the skis retracted back and the skis level or lower at the back.
The skier or prospective skier begins in the starting position which is rigid for entry. There is a wedge at the back of the appal~ s that braces the skis 1 onto the ski shelf 11 from the wedge bracket 12 at the back ofthe app~ s and keeps the skis fixed for entry.
Next the skier next removes the wedge and the skis are able to move. Initially because the skis are 10 retracted to the back ofthe app~ s well behind the center of balance the weight ofthe skier tends to keep the skis and the skier stationely sitting on the back ski shelf 11.
The skier may slide the skis ahead and may rotate the skis side to side at the ankle around the tubular track 3. This rotated position is illustrated in Figure 2.
15 The user is able to tilt the side hill frame 4 which actually raises one ski and lowers the other just as he or she would experience st~nding sideways on a hill. This tilt is illustrated in Figure 2.
As the user passes the center of balance he or she is able to tilt the rOl ~rd tilt frame 6 ahead and back again as he or she changes their center of gravity ahead or behind their center of balance. The front to back center of balance of the appa~ s is the shaft 7 in the middle of the ro~ ~ard tilt plane. The forward 20 tilt is illustrated in Figure 1.
Various limits or steps may be installed to limit the fol wa~d tilt plane 7 and or the side hill tilt plane 4.
Ski poles 8 are im~ ted using rigid tube strong enough to resist the efforts ofthe user to ...a~
balance. As the user and his or her skis are moved through the forward to back range the poles pivot 9 Page#3 of 11 213~8~6 at the bottom and the poles at the top move through the range with the user at ro~ ll distance ahead of their body. The poles are shown in Figure 1 and Figure 2.
Adjll~tm~nt 14 is in~ ded to set the width of the ski spacing to the correct width for tall or short skiers or lean or broad skiers. Separate adj~stment is provided for the front belween the skis and the back 5 between the skis. This is illustrated in Figure 2 and Figure 3.
One way that ski width adjllstment may be achieved is by a threaded rod passing through a threaded nut embedded in the tubular track 3. In this method there is a requirement for a right hand thread on one end of the rod and a left hand thread on the other end of the rod. And there must be a right hand threaded nut to match the right hand thread and a left hand nut to match the left hand thread. In this 10 arrangement, turning the rod one way will move the skis closer and turning the rod the other way will move the skis further apart.
Skis may be ...~in~Ained parallel or ~djll~ted v shaped for snowplow technique that is taught to beginl1el~.
