DESCRIPTION

5

The present invention is a training device, in particular a training device that can be effectively used to simulate a ski movement.

Background of the invention

In the range of current training equipment for cardiovascular training, known training devices have been provided with an electromagnetic generator for generating power for the display computer and offering an interactive, controlled and adjustable counter-resistance. Among these machines are home trainers, ergometers, rowing trainers, steppers, cross trainers, etc. The movement of the pedals and / or arms in the training equipment mentioned herein takes place in a linear movement relative to the body.

It is not possible to simulate a good ski movement if the pedals and / or arms of the training equipment take place in a linear movement relative to the body. The pedals should move sideways relative to the body. By moving the pedals sideways, different muscle groups are trained than when the pedals are moved in a linear movement relative to the body.

[0004] In order to be able to simulate ski slopes of various types and levels of difficulty, the use of an interactive, (heartbeat) -controlled and adjustable counter-resistance is necessary.

[0005] In order to create a safe and responsible training, the user must have the possibility to be able to stop and / or hold the pedals at any desired and desired moment. The drive mechanism of the electromagnetic generator must be able to loosen the pedals on which the user stands if the pedals are not (or are no longer) moving. The electromagnetic generator needs to be able to see the display computer of information by continuing to rotate, despite the fact that the drive mechanism is not driven by the pedals.

In view of the above description and the enormous amount of winter sports / skiing practitioners, it is desirable to have a cardiovascular training device at the disposal of which the ski movement can be simulated in an interactive, yet simple and ergonomically responsible manner. If the previously discussed options were combined in one training device, this could lead to the setting of a new standard for cardiovascular training equipment.

DETAILED DESCRIPTION OF THE PRESENT INVENTION In FIG. 1, the portion of the total training device that is unique is indicated. The construction shown in Figure 1 has been developed in the manner described below at [0012] to [0017], thereby enabling a simulation of a ski movement.

Figure 2 indicates the left pedal sleeve. The pedal axle is sideways at an angle of 7.7 degrees, such that the top of the axle is tilted outwards with respect to the pedal sleeve and is placed leaning backwards 70.1 degrees in the pedal sleeve. Also with the right pedal (3) the axle is placed at the same angles in the device, however with the right pedal (3) the axle is placed in the opposite direction in terms of angle of 7.7 degrees. Both pedals (4) are then adjusted by means of block bearings (25) mounted in the frame (1) whereby during pedal swing the pedals (4) rise sideways and whereby also a tilting effect of the pedals (4) is created. The inner pedal will be positioned higher in gradation as the outer pedal during the sideways pedal swing.

The right pedal (Figure 1, item 3) sits by means of a bearing intermediate rod (10) coupled to the left pedal (2). Figure 3 shows the technical drawing of the intermediate bar (10). Figure 3: The mounted intermediate rod (10) can rotate 3 dimensionally relative to both pedals (4). The right and left bearing housing (12) can rotate at right angles to the upper bearing holders (11). The mounting blocks (13) are attached to the upper bearing holders (11). The mounting blocks (13) can rotate 360 degrees relative to each other through an internally placed thrust bearing. The function of the intermediate rod (10) is that the pedals (4) remain parallel to each other at all times. Because the pedal axes are mounted in the pedals (4) at the angles described in [0012], a height difference is created between the two pedals (4) during the pedal swing. The intermediate bar (10) should keep both pedals (4) at a constant distance, but still be able to rotate and pivot during the height difference between the pedals (4) without the material of the intermediate bar (10) being the pedal tubes (4) touches.

Description of the ski simulation: In the middle position of the pedals (4), seen in relation to the frame (1), both pedals (4) are completely horizontal. As soon as the pedals (4) are pushed to the side, the right pedal (3) will lower in height during the movement to the right. The left pedal (2) is raised at the same time. Because the left pedal (2) is higher at that moment, a descent on a ski slope is simulated in this way, since in practice the leg which is in the valley direction is also placed lower when the leg which points up the hill. As soon as the pedals (4) are subsequently moved to the left, during this specific movement the pedals (4) in the middle will return to the same height. When the pedals (4) are then moved to the left relative to the center, the left pedal (2) will be lower in height when moving to the left than the right pedal (3). A simulation of a ski movement is hereby realized.

[0015] At the top of the right and left pedal (4) the belt tensioners (a right (6) and a left version (5)) are mounted on the pedal tube (Fig. 1, item 4). Figure 4 shows the technical drawing of the complete belt tensioner.

Figure 4 Belt tensioner: The belt tensioner consists of a mounting block (7) to which the toothed belt is attached. The mounting blocks (7) are attached to a shaft (8) which is maintained under tension by a compression spring (15). The tension of the compression spring (15) can be controlled by an adjusting wood (16). The compression springs (15) have a dual function: Maintaining the tension of the toothed belt and ensuring a progressive spring action when the pedals (4) are pressed in the extreme outward position. Upon reaching the outermost pedal position, the spring force of the compression springs (15) causes the pedals (4) to be pressed to the center. This creates a smooth movement. The pressure springs (15) also ensure a low impact on the joints of the user during the extreme, most lateral, pedal positions since the use of the pressure springs (15) does not cause a sudden stop and therefore an impact moment in the movement. .

The toothed belt mounted on the left belt tensioner (5) passes through a gearbox (9). Figure 5 shows the technical drawing of the gearbox (9)

Figure 5 Gearbox: The toothed belt enters the gearbox (9) between a central guide roller (17) and the left clutch (18). The toothed belt runs with the tooth side along the toothed side of the left clutch (18) and is guided out of the gearbox (9) via the central guide roller (17) between the right toothed clutch (19) and the central guide roller (17) and is then attached with the other side to the right belt tensioner (6).

When the pedals (4) are moved, the toothed belt starts moving the couplings (18) (19). If the left-hand coupling (18) turns clockwise, the right-hand coupling (19) rotates counterclockwise. The rotation of the couplings in the opposite direction from each other is realized in that the plastic gear wheels (20) (21) rotate into each other which are mounted on the same axes as the underlying couplings 5 (18) (19). The couplings (18) (19) contain a so-called freewheel bearing. The left-hand coupling (18) runs on a long axis (22) and the right-hand coupling runs on the short axis (23). The pulley wheel mounting is mounted on the top of the long shaft (22) (24). When the pedals (4) are pushed to the right, the toothed belt ensures that the left-hand clutch (18) grips the long shaft (22), while the right-hand clutch (19) runs freely over a short shaft (23). Because the left-hand coupling (18) sets the long shaft (22) in motion, the pulley wheel (24) also starts to rotate at the top of the gearbox (9). When the pedals (4) are pushed to the left, the toothed belt causes the left clutch (18) to rotate in the opposite direction, thereby freeing on the long shaft (22). The right-hand coupling (19) engages the short shaft (23) at that moment. Because the left clutch (18) is at that moment free running along the long axis (22), the pulley (24) on the top of the gearbox 15 (9) continues to rotate in the same direction than when the pedals (4) are pushed to the right . As a result, the pulley wheel (24) on the top of the gearbox (9) turns in the same direction at all times, regardless of which side the pedals (4) are pushed to.

The pulley wheel attachment (Figure 5, item 24) mounted on the top of the gearbox (9) 20 floats by means of. a Poly V belt on the electromagnetic generator. The function of the electromagnetic generator is 2-sided: 1. The display computer is supplied with energy and 2. the generation of electromagnetic resistance, so that different intensity levels can be selected by the user.
