Abstract

The object of the invention is to construct a device for physical training which mimics the whole movement in classic skiing on snow, i.e. a device for stacking, double stacking and diagonal skiing with extension. The resistance for stacking and firing with legs can also be connected. This makes it possible to create track profiles with the help of a computer that controls the load and in that way obtain travel profiles and movement patterns that mimic reality as much as possible. This is achieved with a device defined in the following claims. The device consists of two swings which are each connected to a separate ski. The ski is designed so that it hangs loosely in the air, can be stood on and has a stop block with which the shot is made. The ski is together with the poles connected to a common resistance device that provides resistance when pulling and sliding with skis. This is to mimic real skiing as much as possible.

Description

Technical field The invention relates to a device for physical training for cross-country skiers and other athletes Background Skiing is a popular and gentle training method that provides good cardio training for the whole body. The problem is that when there is no snow, in addition to roller skis, there are no training equipment that mimics the entire skiing movement. Skiing is partly based on pole vaulting where you stake yourself with poles, but also on so-called diagonal skiing and double pole vaulting where you shoot away from the ski with the help of your legs at the same time as you shoot from there with the pole. Roller skiing is a training method that is regularly used by cross-country skiers and other athletes. Roller skis, however, have many shortcomings, it is partly dependent on physical conditions such as road conditions, weather, terrain, etc. In a big city, it can be difficult to find good roads for roller skiing and with all intersecting roads and road users, it can be directly life-threatening to go roller skiing. In addition, stacking on hard asphalt can put unwanted strain on the back, shoulders and arms.

Many training devices used today simulate stacking with more or less good imitation. There is currently no training equipment on the market that mimics the entire skiing movement with staking, diagonal skiing and double staking, with the possibility of pushing back with legs. Some specialized training facilities have large treadmills that have been used for roller skiing, but they are so large and expensive that they are not suitable for private individuals or ordinary gyms. These equipments are also powered by electricity, which is both expensive and can also be difficult to access in some places.

Today, as I said, there are some products on the market that simulate cross-country skiing. An example is "Concep2 SkiErg" (www.motion.se) which is built-up co-fan resistance. This is primarily a strength training machine. The similarity to cross-country skiing is particularly high.

Another example of stacking equipment is the "Thoraxtrainer" (www.thoraxtrainer.com). Here the rods are attached to a cart that rolls on rails. The poles cannot be lifted from the rails and thus the correct movement pattern for skiing is not achieved. When fired, however, the imitation is good.

Ercolina is a training equipment that is similar to the SkiErg, but here the resistance is instead magnetic.

None of these stacking machines simulate skiing on snow particularly well as they are very monotonous and rigid. The feet are completely locked and it is not possible to get the same forward-leaning position on the body as when skiing on snow where the body and feet move forward. Because the practitioner when moving on snow moves forward, it is also possible to get a more Page 1 of 5 Appendix: Description Ski machine application 1630008-9 forward-leaning position when stacking. The forward movement simply makes the practitioner naturally lean forward more compared to if the practitioner is standing still on a floor.

An equipment that provides both arm and leg training is Nordic Track Ski (www.nordictrack.com). You pull on a strap with your arms and move your legs back and forth. The disadvantage is that this machine is best suited for diagonal skiing, i.e. not stacking or double stacking. There is also no connection between the leg and arm load, which means that the feeling of skiing is not very good. There is also no possibility to make a so-called shoot, which is the local practitioner pushes the ski firmly into the hill to thus get a foothold and be able to shoot away.

There are also some other similar ski training machines, but today there is no machine that all classic riding techniques can be practiced on, which has a clear firing mechanism and where the legs and arm movement work against the same resistance. There is no exercise machine where the pole movement results in a forward movement of the whole body similar to that when skiing on snow. That the arm and leg resistance are connected is important for as much as possible imitating normal skiing. In normal skiing, you usually stake where it is easy and when you get to an uphill slope and it is heavy, you put on the kick with your legs.

Figure 2 shows the device set from the side when the practitioner performs diagonal riding and the skis and the poles move oscillating movements back and forth. Figure 3 shows the construction from the side when the practitioner performs only staking, the resistance that arises in the poles causes the skis and the practitioner to move forward.

The invention consists of two parallel skis 2 which are connected to each front pendulum arm 1 and rear pendulum arm 5. The frame of the device consists of bottom plate 24 with frame 8 and intersecting support elements 9 which support the front pendulum arms 1 and rear support elements 7 which support the rear pendulum arms 5 Swing arms 1, 5 have rotary shafts in the support elements 7, 9 and are each rotatably connected to skis 2. This means that the practitioner can stand on the skis 2 which can be rocked back and forth in a single swing movement. A resistor is connected to the skis so that resistance arises when the skis 2 are pushed apart. In order for the resistor to have the desired function, it is constructed in the following way. Pendulum arms 1 are connected via two line elements 12, 13 directly to two of the flywheels 20, 31 of the flywheel 20 with associated return mechanisms 34, 35. The return mechanisms consist for example of a spring, elastic band or coil 22 which at one end is attached to the structure 28 and at the other end attached to a chain 21. The drive mechanisms in turn consist of a chain 21 which runs via gears 18 with freewheel function and then merges into a line element 12, 13, 15, 16, 27 which then runs on to pendulum arms 1 or the rods 6. Gears 18 and flywheels 20 is mounted on flywheel shaft 19 which is freely rotating and fixed in stand 26. When then the skis 2 are pushed apart from the starting position, line elements 12, 13 are pulled out and chain 21 (drive mechanisms 26, 31) pulls gear 18, shaft 19 and flywheel 20. Spring, elastic belt or spool 22 (return mechanisms 34, 35) then pulls in the line element 12, 13 and because the gear 18 has a freewheel function, the flywheel 20 will not be affected when the line the item is returned to its original position. The line element can be connected so that it goes directly from pendulum arms 1 to the flywheel drive mechanisms 26, 31 and return mechanisms 34, 35 or the line element goes via pendulum arm 1 through pulleys 10, 11 which sit on the stand a bit up along pendulum arm 1 and run along pendulum arm 1 via pulleys 23 at the pivot axes 29 of the front support element 9 further to proposed pulleys 17 and then to the flywheel drive mechanisms 26, 31 and return mechanisms 34, 35. Because the line element moves via pulleys 10, 11, the line element will be pulled out both when skis 2 are pivoted forwards and backwards. via line elements 15, 16 directly connected to the flywheel's two drive mechanisms 32,14 and return mechanisms 25, 33, respectively, and functions as such that when the practitioner performs a Page 3 of S Appendix: Description Skidmaskin application 1630008-9 stacking movement and pulls line elements 15, 16 backwards is increased the speed of the flywheel 20 and the proximity arms are advanced for a new rod pull, the line element 15, 16 freely into the return mechanism 25, 33 without affecting the speed of the flywheel 20. Because both skis 2 and rods 6 are each connected via drive mechanisms 26, 32, 14, 31 to the flywheel 20 with associated return mechanism 25, 33, 34, 35, a feeling of movement is obtained which is very similar to that of classic cross-country skiing on snow. Each rod 6 and sheath 2 affects the single flywheel 20 and its rotational speed. It is possible e.g. to drive the flywheel 20 by commuting with the skis 2 at the same time as commuting with the arms so-called diagonal skiing, it is also possible to stand still with the skis 2 and to only drive the flywheel 20 with a pile with the rods 6. The resistance that arises during piling automatically causes the skis 2 to be oscillated a bit (see figure 3). This gives the practitioner a more forward-leaning position compared to standing still and exercising on a regular stacking machine where the feet are locked to the ground. The forward movement and the forward-leaning position are very similar to that when skiing on snow and makes the feeling when stacking much better than a ordinary stacking machine. The construction also means that it is possible, for example, to stand still on the skis 2 and drive the flywheel 20 by simply sticking with one of the rods 6. Another possibility is to drive the flywheel 20 by oscillating with the skis 2 without touching the rods 6. Line elements 12, 13, 15 , 16, 27 are releasably attached to the return mechanism 25, 33, 34, 35 which makes it possible to disconnect, for example, line elements 12, 13 from pendulum arms 1 and then get a clean swing without resistance on which stacking can be performed. This still gives the desired forward movement when self-tapping. The resistance of the flywheel 20 can be varied by being coupled to a magnetic brake, belt brake, reverse brake, air brake, water brake or some other type of brake. The resistance can then be connected to a computer that can be programmed so that the degree of resistance is varied automatically and in that way create ski profiles that are similar to the reality of skiing in an exercise track.

In order to save space, the construction can also be constructed without rear pendulum arms 5 with only one front support element 9 with pendulum arms 1. This is done by the practitioner standing on a standing plate 30 which is attached to each front pendulum arm 1 as in figures 6a, 6b, 6c, 6d .

Another alternative construction is that line elements 12, 13 are connected to a common line element 27 and then a common drive mechanism 31 and return mechanism 34. See figure 7. When the skis 2 oscillate, the right ski will move forward as much as the left ski moves backwards. This allows line elements 12 and line elements 13 to join together and form line elements 27. Line elements 27 are then connected to drive mechanism 31 and return mechanism 34.

Under the ski 2 and against the fixed surface, there are fixed adjustable triangular blocks 3, 4 mounted. These are used for sliding with the skis 2. By sliding is meant that either the right or left ski / standing plate 2, 30 is in its rearmost position, so the blocks 3, 4 take each other and friction occurs. The friction allows the practitioner to push away and push the front ski / stand plate 2, 30 which is oscillated forward. As the angle of the block (contact surface) can be varied Page 4 of 5 Appendix: Description Ski machine application 1630008-9 different degrees of resistance occur when shooting. If the blocks 3, 4 are both placed with a vertical hypotenuse, 100% contact area is obtained. If the blocks 3, 4 are rotated so that the hypotenuse is more horizontal, a smaller contact surface is obtained when the shot is fired. The similarity can be made when you have a backstory when skiing, a greater force is required down into the skis to get a grip on the ski (in these drop blocks) and thereby be able to make a good shot. With a small contact area on the stop blocks3, 4, a greater force downwards is required to get a good shot. The distance between the block 4 underside and the block 3 which is attached to the base / construction can also be varied and in this way the length of the rear kick, i.e. how far behind the ski / stand plate 2 the pendulum must be, the blocks 3, 4 make contact and push-ups can be performed varied. By varying the angle and location of the blocks 3, 4, technical training can be practiced when shooting.

On the skis 2 there are bindings mounted, either in the form of clips or straps to attach, for example, jogging shoes, but it can also be ordinary ski bindings with ski boots.
