1 shows first in a side view from the left the training device 100 with its components. Behind each of the components shown, which are visible in the side view from the left, are each the one in the direction of the user 10 arranged right components, according to 2 , To Therefore, in the description of the following 1 each described the parent component without naming the respective left or right component.

The user 10 stands with his feet 30 on the tread plates 26 on straps 24 are arranged and their displacement on foot plate pivot bearings 28 is guaranteed. The carriers 24 themselves are on carrier sway camps 20 arranged displaceably, wherein the carrier pivot bearing 20 on a floor plate 34 are arranged.

On the bottom plate 34 are additional storage elements 16 arranged, at which over connecting elements 18 around a third y-axis y ₃ pivoting pushers 12 are arranged by the user 10 can be recorded in the upper area. The respective push element 12 is in an upper part of the pusher 12A and in a lower part of the pushing element 12B divided, with the parts 12A . 12B via telescope elements 14 connected to each other. Within the training device 100 are several load cells 22 arranged according to 1 in and / or on the telescopic elements 14 in the area of the carrier pivot bearings 20 and / or in the area of the footplate pivot bearings 28 and / or the bearing elements 16 can be arranged.

The representation according to 1 is subsequently by 2 explained in more detail, wherein the top view of the training device 100 while cutting in an xy plane 2 the training device 100 Plotted in a zx plane.

2 again shows the bottom plate in plan view 34 on which a left and a right vehicle pivot bearing 20L . 20R are visible. The left and right carrier pivot bearings 20L . 20R is arranged on a second y-axis y ₂ . The left and right carrier pivot bearings 20L . 20R carries spaced ( 1 ) to the bottom plate 34 the left or the right carrier 24L . 24R , At the exposed end of the left or right support 24L . 24R is the left or right footboard 26L . 26R arranged. The left or right footboard 26L . 26R is over the left or right foot plate pivot bearing 28L . 28R to the left or right carrier 24L . 24R ( 1 ) spaced apart.

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

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

The left or right footboard 26L . 26R is in 2 represented as an imaginary center line in the longitudinal direction of the left and right tread plate 26L . 26R not with the centerline of the left or right wearer 24L . 24R aligned corresponds. For the left or right footboard 26L . 26R However, all are position along the xy plane with rotation about the first and second z-axis z ₁ , z ₂ both in the initial position and in pivotal position z1 'and z2' of the left and right footboard 26L ' respectively 26R ' and of course conceivable in all intermediate positions.

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

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

According to the invention, the force transducer 22 in the field of tread plates 26L . 26R be formed so that only displacements in the desired direction of displacement or partial displacements in the desired Ver storage direction are executable.

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.

That in the 1 and 2 described training device 100 thus serves as a replica of the movement that is performed in cross-country skiing, especially in Nordic skating. The movement is done by pushing the legs of the user 10 along its shoulder axis and not by a forward movement of the legs. The user 10 starts in the starting position, with the legs (feet 30 ) are arranged below the shoulder. The hands of the user 10 capture the pushers 12 at eye or shoulder level. The user 10 stands slightly perched on the training device 100 ,

The movement on the exercise machine 100 is then done as follows: The user 10 makes a lunge step with a force component forward in the x-direction and a lateral force component in the y-direction, for example, first by applying force to the right tread plate 26R and simultaneous transfer to the right vehicle 24R , and thus generates a pivoting movement in the region of the second z-axis z ₂ about the right foot plate pivot bearing 28R and the right carrier swivel bearing 20R , His body weight remains on his right leg. The user 10 shifts his body center of gravity. From this he gains the necessary momentum, around the right foot 30 push away to the outside. The right footboard 26R is - as described - variable on the right foot plate pivot bearing 28R attached and can adapt to the positions of the feet in all spatial directions x, y, z. The left leg, respectively 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 analogous to the executable movement of the left leg to the left footboard 26L be transmitted. Here again, therefore, a movement of the left leg with a force component in the x-direction forward and substantially lateral y-direction on the left footboard 26L executed. 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 in the training device 100 executed mechanism is sufficiently variable for this purpose.

The training device 100 allows the simultaneous movement of the arms in different 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.

Further becomes a "symmetrical Two-one "as Arm swing technology allows, In this case, only with every second leg repulsion is a double-decker push. The Symmetrical Two-One is the fastest Step and allows the biggest speed.

Finally, the training device allows 100 in terms of arm technology, the "asymmetric two-one". 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, their movements in an excellent manner by the training device 100 can be simulated.

The Device can primarily used in gyms. Thanks to the whole body movement it can be supportive are used as cardio training and it is equally as Preparing for a cross-country winter season.

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