The invention will be explained in more detail in an embodiment with reference to the accompanying drawings. Show it:

FIG. 1

a side view of a training device from the left and

FIG. 2

a plan view of the training device.

Figure 1 shows first in a side view from the left training device 100 with its components. Behind each of the components shown in the side view from the left are each located in the viewing direction of the user 10 arranged right components, according to Figure 2. Below, therefore, in the description of Figure 1 respectively the parent component without mentioning the respective left or right component described.

The user 10 stands with his feet 30 on the tread plates 26, which are arranged on carriers 24 and their displacement is ensured by step plate pivot bearing 28. The carriers 24 themselves are arranged to be displaceable on carrier pivot bearings 20, wherein the carrier pivot bearings 20 are arranged on a base plate 34.

On the bottom plate 34 bearing elements 16 are additionally arranged, on which via connecting elements 18 about a third y-axis y ₃ pivotally thrust elements 12 are arranged, which can be accommodated by the user 10 in the upper region. The respective thrust element 12 is divided into an upper part of the thrust element 12A and into a lower part of the thrust element 12B, wherein the parts 12A, 12B are interconnected via telescopic elements 14. Within the training device 100, a plurality of force transducers 22 are arranged, which according to FIG. 1 can be arranged in and / or on the telescopic elements 14 in the area of the carrier pivot bearings 20 and / or in the area of the step plate pivot bearings 28 and / or the bearing elements 16.

The representation according to FIG. 1 is explained in more detail below by FIG. 2, wherein the top view crosses the exercise device 100 in an x-y plane, while FIG. 2 shows the exercise device 100 cut in a z-x plane.

Figure 2 shows in plan view again the bottom plate 34, on which a left and a right carrier pivot bearing 20L, 20R are visible. The left and right carrier pivot bearings 20L, 20R are arranged on a second y-axis y ₂ . The left and right carrier pivot bearings 20L, 20R are spaced (Figure 1) to the bottom plate 34 of the left and right brackets 24L, 24R, respectively. At the exposed end of the left and right beams 24L, 24R, respectively, the left and right tread plates 26L, 26R are disposed. The left and right tread plates 26L, 26R are respectively via the left and right foot plate pivot bearing 28L, 28R to the left and right support 24L, 24R (Figure 1) arranged spaced.

In an initial position, the vertical first or second z-axis z ₁ , Z ₂ lie on a first y-axis y ₁ extending transversely to the viewing direction of the user 10. Similarly, there is a third or fourth vertical z-axis z ₃ , z _{4 of} the left and right carrier pivot bearing 20L, 20R on the second y-axis y ₂ . The step plate pivot bearings 28L, 28R are in the illustrated starting position on a third and fourth x-axis x ₃ , x ₄ within the carrier pivot bearings 20L, 20R on a second and fifth x-axis x ₂ , x ₅ , so that during a pivoting movement of the respective Carrier 24L, 24R on the forces acting on the respective tread plates 26L, 26R forces first slight forward movement and mainly pivotal movement on a left or right circular path 32L, 32R is performed.

Not shown in Figure 2 but equally according to the invention is an arrangement in which the step plate pivot bearings 28L, 28R and the carrier pivot bearings 20L, 20R are not arranged on different x-axes x ₂ , x ₃ and x ₄ , x ₅ , but that the respective carrier pivot bearings 20L, 20R and the respective step plate pivot bearings 28L, 28R are aligned on a common x-pivot axis, for example, the second x-axis x ₂ or, for example, the fifth x-axis x ₅ . Of course, as a common axis and the third x-axis x ₃ and the fourth x-axis x ₄ in question.

The left and right tread plates 26L, 26R are shown in Figure 2 so that an imaginary centerline in the longitudinal direction of the left and right treadboards 26L, 26R, respectively, does not correspond to the centerline of the left and right brackets 24L, 24R, respectively. For the left and right tread plates 26L, 26R, however, all the positions along the xy plane are rotated about the first and second z-axes z ₁ , z ₂ both in the home position and in the pivotal positions z1 'and z2', respectively, of the left and right tread plates 26L 'or 26R' and of course in all intermediate positions conceivable.

The left or right tread plate 26L, 26R is thus also vertically in the z-direction Z ₁ , Z ₂ displaced and can tilt forward and back on an imaginary x-axis or to the left or right on an imaginary y-axis and is thus displaceable in all spatial directions x, y, z.

A shift in the respective spatial directions x, y, z is to avoid untypical foot postures with respect to the skating movements by appropriate stops (not shown) of the left and right footboard 26L, 26R executable by suitable elements.

According to the invention, the force transducers 22 in the region of the tread plates 26L, 26R can be designed so that only displacements in the desired direction of displacement or partial displacements in the desired direction of displacement can be carried out.

As a force transducer 22 come spring elements, damping elements, torsion bars with or without additional locking elements for the realization of attacks or the like between the respective components in question.

The training device 100 described in FIGS. 1 and 2 thus serves to simulate the sequence of movements that is carried out in cross-country skiing, especially in Nordic skating. The movement is made by pushing the legs of the user 10 along his shoulder axis and not by a forward movement of the legs. The user 10 starts in the home position with the legs (feet 30) located below the shoulder. The hands of the user 10 capture the pushers 12 at eye or shoulder height. The user 10 stands slightly perched on the training device 100.

The movement on the exercise machine 100 is then as follows: The user 10 makes a lunge with a force component forward in the x-direction and a lateral force in the y-direction, for example, first by applying force to the right tread 26R and simultaneously transmitting to the right Carrier 24R, and thus generates a pivoting movement in the region of the second z-axis z ₂ to the right foot plate pivot bearing 28R and the right Carrier pivot bearing 20R. His body weight remains on his right leg. The user 10 thus shifts his body center of gravity. From this he gains the necessary momentum to push the right foot 30 outwards. The right tread plate 26R is variably mounted over the right treadstock pivot bearing 28R as described, and can be adapted to the positions of the feet in all spatial directions x, y, z. The left leg, or the left foot 30, remains approximately in the basic position. Preferably, the force increases with the removal of the leg from the starting position.

If the center of gravity is shifted to the right side, the counter movement begins. The weight is now shifted to the left leg and the description of the skating step on the right footboard 26R can be analogously applied to the left leg's operative movement on the left footboard 26L. Here again, therefore, a movement of the left leg is performed with a force component in the x-direction forward and substantially lateral y-direction on the left tread plate 26L. The right leg is dragged behind, until about the home position is reached again. The center of gravity is now above the left leg. Then the described counter-movement starts again to the right.

The movement allows the arms to be used in the opposite rhythm or in synchrony with the movement. The executed in the training device 100 mechanism is sufficiently variable.

The training device 100 allows the simultaneous movement of the arms in various arm techniques. On the one hand, an arm movement is executed, which is called the "one-stroke". Here is done with each lateral leg repulsion a Doppelstockhub.

Furthermore, a "symmetrical two-one" as arm swing technology allows, this is done only at every second leg repulsion, a double-decker thrust. The "symmetrical two-one" is the fastest step and allows the highest speed.

Finally, the training device 100 allows the "asymmetrical two-one" with respect to the arm technology. Here, the sticks are not used in parallel, but slightly offset. The guide arm determines the body side, which is more stressed in this technique.

The training device 100 also allows the following steps of modern skating: Executable is the one-stroke, two-stroke, half-skate and the diagonal skate, whose movements are excellently simulated by the training device 100.

The device can primarily be used in gyms. Thanks to the full-body movement, it can be used as supportive cardio training and it is equally suitable as a preparation for a cross-country winter season.

Finally, by means of adapted adapters on the training device 100, cross-country skiing shoes can also be tested, which also results in a suitable use in the sales area of sports shops.
