Detailed Description of Preferred Embodiments Fig. 1 shows an embodiment of the present invention.

The figure shows a training tool 1 consisting of rod members 2 and resistance members 3. The rod member 2 is provided with gripping members 4, 5 placed on either side of the rod member and acting as handles. The handles are preferably equipped with straps 7, 8 to enable a user 9 to hold the rod member in a firm grip with their hands 10, 11. Furthermore, the training tool is provided with a support 15 on which the user 9 stands. One end of the support 15 consists of a vertical part 16 arranged to act as a support for the resistance means 3.

The rod member 2 is connected to the resistance members 3 via a tow line 12, which is constituted by a nylon strap and is fastened in a fastening member 27 arranged on the rod member, e.g. a loop.

The pull line 12 is wound at its other end on a winding coil 28 arranged in the resistance means 3 on a shaft 13. An axial fan 14 is also mounted on the shaft 13. 71877 .d0c; 2002-12-23 10 15 20 The training tool described in figure 1 is particularly well suited for training so-called bar movements that are characterized by a practitioner's hands, arms, torso and leg movements giving power to two rods that move freely on each side of the practitioner's body. The pole movements are a very important element in both classic and freestyle in cross-country skiing today.

To perform bar movements, a user 9 grabs the handles 4, 5 with his hands and pulls them down / backwards to perform a typical bar movement. This movement causes the rod member 2 to move from the initial position shown in solid lines in Fig. 1 to a second position. In the initial position the bar member 2 is in a substantially upright position, with its lower end at a point B, where a shaft A through the longitudinal direction of the bar member forms a first angle d relative to a plane constituted by the training equipment base, and where the handles are in front of the user shoulders. . In the second position, the lower end of the rod member has been moved from point B to point C, which relative to the user is behind him.

Furthermore, the shaft A forms through the rod member 2 in the second position an angle ß to the ground which is smaller than the angle α, and the gripping means are located behind the user's shafts.

The rod member 2 may at its lower end 20 be provided with guide means in the form of e.g. a wheel 21 guiding the lower end of the rod member along a path from the initial position B to the point C.

This causes the movement of the rod member from the initial position to the second position to become smooth.

During the movement from the initial position to the second position, the tow line 12 is pulled out, which causes the shaft 13 to rotate. The rotation of the shaft 13 in turn causes the axial fan 14 to start rotating, the air resistance acting on the rotating fan 14 71877 .d0C; 2002-12-23 10 15 20 525 875 o o o o o o o o o o o o o o o o o o o o o o o o o o o o o o o o o o o o o o o o o o co o no o o o o co o no o o o o o o o co o no o o o o o o o o o o o o o

As the towline is pulled out, the diameter of the towline winding on the winding spool 28 decreases, so that, at a constant pulling speed of the towline, the shaft will rotate faster and faster. This means that the fan also rotates faster and faster, which in turn has the effect that the air resistance and thus the resistance experienced by the user increases. The user's experience is thus a low starting moment followed by a natural increase in resistance during the pole movement, which is in good agreement with real conditions in the ski tracks.

The resistance means 3 also comprise a return line 22 which is wound at rest on a spring-loaded drum 23. The other end of the return line is fastened in a winding drum 29 mounted on the shaft 13.

At the same time as the tow line 12 is pulled out of the shaft 13, the return line 22 is pulled out of the drum 23 and rolled up on the winding drum 29. When the user has performed the bar movement, i.e. the rod member is in the second position and the extraction of the tow line has been completed, a freewheel 24 ensures that the fan 14 is disengaged from the shaft. The fan acts as a flywheel with flywheel and will thus continue to rotate.

When the user then reduces or completely stops the force that has been applied to the rod member via the handles 4, 5 to perform the stacking movement, so that the return force of the return line 22 (originating from the spring-loaded drum) exceeds the force applied to the handles 4, 5, 718774100; 2002-12-23 10 15 20 5 3 5 8 75 the return line 22 to roll in on the drum 23. This causes the shaft 13 to rotate in the opposite direction, which results in the pull line 12 being pulled in and wound up on the spool 28. This winding also results in the lower end of the rod member 2 being returned to the initial position, whereby the rod member 2 independently of the other movements of the user 9 reaches the initial position to enable a new rod movement. When the tow line 12 is retracted, the fan 14 is disengaged as above so as not to counteract the rolling of the return line 22 and the tow line 12. When the user then performs the next rod pull, the fan still rotates due to its pivot mass, which corresponds to speed under the skis begins the next pole vault, the beginning of this is perceived as in principle irresistible, which is rough in accordance with the beginning of a pole vault when skiing on snow or asphalt.

The resistance provided by the axial fan 14 can be regulated by the user by adjusting the air flow. By restricting the flow of air by means of a damper (not shown), the resistance is reduced. Correspondingly, the resistance can be increased by opening the damper. As shown in Fig. 1, the air outlet may be provided with adjustable guide rails 25, so that the user can direct the air flow 26 towards himself in order thus to obtain a true-to-nature speed wind feeling and / or a cooling effect.

It should be noted that the size of the resistance means illustrated in Fig. 1 need not be representative but may be considerably smaller.

Instead of using a support plate 15 as in Fig. 1 which provides resistance to the resistance means 30, the resistance means can alternatively e.g. anchored to a wall, stair railing or door. 71877.d0C; In: J: JH OO * Q LN Furthermore, the resistance means 3 at the shaft 13 may be equipped with a sensor 30 for transmitting signals representing rotations of the shaft 13 to a unit 31, e.g. of the cycling computer type, which by means of the transmitted signals converts the rotation of the axle to a distance and a speed, after which these calculated values can be shown to the user on a display 32 arranged on the unit 31. The user can thereby see the distance traveled and average speed during the training session. The unit 31 can also be arranged to show a time that the training session has been going on and an estimated calorie consumption. To calculate the calorie consumption, a pressure sensor for measuring the force between the resistance means and the support plate can be arranged between the support 15 and the resistance means. The signals from the pressure sensor are then transmitted to the unit 31 which, by the measured force, can calculate the calorie consumption.

The rod member 2 can also be adjustable in length to fit people who are different lengths and / or use different length rods. This is illustrated in Fig. 2 which shows the part of the rod member 2 marked with dashed lines in Fig. 1.

As shown in Fig. 2, the rod member 2 consists of two parts 33, 34.

The part 33 is provided with heels 35-37. The part 34 runs partly inside the part 33 and is provided with a spring-loaded pin 38 with a spherical or conical surface 39. When the spring-loaded pin meets a hole 35-37 in the part 33, the spring pushes out the conical surface in the hole, the part 34 being locked in the part 33. The user can then change the length of the rod member by pushing in the pin 38 at the same time as the part 34 is pushed in further or pulled out from the part 33. When the pin again ends up in the middle of a hole, it is pushed by the spring into the hole, which locks the parts relatively each other in the new mode. In this way, 718774106; 2002 ~ 12-23 10 15 20 oo ou tion no I .O I O I å! 0000 OI. .oó .. na øouo Q Ü Ü Ö. n. u »u I - I" ° J "u" ozone n "5 a. »O no m I m co -1 ou 10 the user like a crutch or a vacuum cleaner handle regulate the length of the rod member.

Fig. 3 shows an alternative embodiment of the training tool in Fig. 1. The training tool 40 in Fig. 3 is similar to that in Fig. 1, except that the end of the tow line, which in Fig. 1 is attached to the rod member, in Fig. 3 instead is attached to a point 41 on the resistance means, and runs via a pulley 42 arranged on the rod means. This connection between the rod means and the resistance means means that the pulling line in the rod movement described in connection with Fig. 1 will be pulled out twice as fast, which in turn increases the speed of the fan.

This enables a very strong resistance to the rod movement because the air resistance increases exponentially with the speed.

Thus, the training tool can provide proper resistance even to the most well-trained. If the pole member is provided with fastening means for the tow line both in the form of a loop and a pulley, the training tool can be quickly and easily adapted to provide demanding resistance, regardless of whether the user is an elite athlete or an exerciser.

An alternative to increasing the resistance is that instead of returning the tow line to the resistance means as in Fig. 3, letting the tow line run along the rod member to be attached to a movable fastening device on the rod member. In this way, the starting diameter of the winding of the towline can be changed, which means that the further up on the rod member the towline is attached, the greater the resistance obtained due to the ever smaller diameter of the dragline winding.

Figs. 4a-d show a further embodiment of the invention. Fig. 4a shows two views of a training tool 50 which consists of a single unit consisting of 71,877. doc; 2002- 12 -23 10 15 20 5 f: 5 s: 7 z: q. 11 shows a tubular rod member 51 with resistance means 52 mounted thereon. As in Fig. 1, the training tool comprises gripping means 54, 55 acting as handles.

As in Fig. 1, the tow line 56 is wound on a winding coil 58 arranged in the resistance means 52 on a shaft 57, as shown in Fig. 4b. The tow line runs in Fig. 4a inside the rod member 51 and further out via a pulley 59 in the lower part of the rod member 51 and is fastened in e.g. a wall 60. When the rod movement described above is performed and the lower part of the rod member moves from the point A shown in Fig. 4a to the point B, the pull line is pulled from the winding spool 58 and through the rod member 51, which as described above causes an axial fan 61 to rotate give resistance. The mounting of the fan at the top of the rod member means that it also blows air directly towards the user to give a true-to-nature feeling of speed wind and / or a cooling effect. The return line 64 is in this case, instead of being wound on a separate drum as in Fig. 1, wound on the shaft 57 and acts as a roller blind spring.

The embodiment shown in Figs. 4a-d has the advantage that the training tool consists of a single unit and can be placed under e.g. a bed when not in use.

In this case, the tow line is arranged to run inside the rod member, but can also be arranged to run on the outside.

Fig. 4c shows that this embodiment can also be used with a gear ratio transmission line. In this case, instead of the end of the towline, a pulley 62 is attached to the wall 60, the towline running around the pulley and being attached with a loop 63 of 71877.d0C; 2002-12-23 10 15 20 BJ LH 0000 0 0 0 00 50 00 0000 00 O OO O I! I 0 0 0 0 0 0 0 0 00 ä? stave organ skirt. As in Fig. 3, this coupling causes the towline to be pulled out twice as fast with the accompanying markedly increased resistance.

Like the embodiment shown in Fig. 1, the rod member 51 may be equipped with a unit, e.g. of bicycle computer type, to show the distance traveled and average speed during the training session. In order to calculate the calorie consumption, the pressure sensor can in this case be mounted at the attachment of the tow line to the wall to measure the force that the tow line exerts on the attachment.

Fig. 4d shows an alternative embodiment of the resistance means in Fig. 4b. As in Fig. 4b, the tow line 70 is wound on a winding coil 72 arranged in the resistance means on a shaft 71. The resistance means also comprise a return line 73 which functions as a roller blind spring.

The resistance means are also in this case provided with a fan 74, but unlike before the fan 74 is fixedly mounted to the shaft 71 without being connected via a freewheel, and enclosed in a fan nozzle 75. Furthermore, the resistance means are provided with dampers 76 which at rest is kept closed via springs 77. When pulling out the tow line 70, the air will flow the path marked by arrows 78 through the fan nozzle 75, the air pressure opening the dampers 76 and the fan 74 giving resistance to pulling out the pull line. When the pull-out movement stops, the fan also stops because it is fixedly mounted on the shaft.

When the towline is rolled up, the air damper is closed by means of the springs 77, whereby the fan, which now rotates in the opposite direction compared to when pulled out, is allowed to work in vacuum, which leads to it exerting a very small resistance.

The fan 74 is made of a light material because it should not have a flywheel mass. This means that 7l877.dOC; 2002-12-23 10 15 20 bd UI oo oo oooo oo oo oo oolo o o o o o o o o o o o o o o. The resistance device, and thus the entire training tool can be made very light, which in turn means that the training tool can be easily picked up and set aside as needed.

The invention has been described in the above description with an axial fan as a resistance means. The fan can of course just as easily be of the radial type. Instead of a fan, e.g. a friction brake or magnetic brake can be used. Furthermore, the described towline consists of a nylon strap. Of course, the towline does not have to be a nylon strap or be strap-shaped at all. The tow rope can just as easily consist of a steel rope or some other type of rope that is capable of performing the described function.

The pole member described above can also be used as a ski pole for skiing, both on snow, ice and asphalt. As pole vaulting has become increasingly important in cross-country skiing, the pole according to the present invention can replace the traditionally two poles with a single pole. Figs. 5a and 5b show examples of embodiments of such rod members. In FIG.

Then two views are shown of a rod member 80 similar to that described above with gripping members 81, 82 arranged on the rod member and connected to the upper part of the rod member, acting as handles. Instead of the rod member 80 being provided with guide means at its lower end, the lower end is instead provided with a contact member for snow, ice and / or asphalt in the form of a conventional rod tip 83. The contact means can of course also be designed as spikes or other suitable means for attaching to snow, ice and / or asphalt. The rod member described in Fig. 5a can thus be used for skiing on snow and ice where the user can collect the force from both arms to a single point of contact with the snow. 71877.d0C; 2002-12-23 10 15 00 00 00 0000 0 0 0 0 0 0 0 0 0 00 0 00 0000 0 0 0 0 0 0 0 0 0 U 00 00 00 0 0 0G 00 0000 0 0 0 0 0 OI 0 0000 00 ä? -7 g. 00 0000 Ö 2 ":: n E I O '": .E _, I 0 0 90 0 a o i u 0 0 I 0 .: 0 un 0 I 4 2 å.' ~. 0 0:00 000 I 004 '.

Fig. Sb shows two views of an alternative embodiment of the rod member. In Fig. 5b, the gripping means 86, 87 of the rod member 85 are instead connected to the lower part of the rod member. The pole member also comprises a pole tip 88. This embodiment may be preferred when skiing to avoid pole members walking between the legs.

The rod member described in Fig. 5b can of course also be used in the training tool described above. In this case, the rod tip 88 is replaced with a fastener for the towline and a wheel. The pole members shown in Figs. 5a and Sb can be provided with quick couplings in order to be able to switch between pole tip and fastening means / guide means, respectively, which enables the same pole means to be used both for skiing and for training with the training tool. 718774106; 2002-12-23
