Definitions
- the invention relates to a training device for the summer training of cross-country skiing.
- Such roller skis or roller skis for summer training for cross-country skiing have been known for a long time.
- the individual embodiments differ significantly.
- ski rollers with a wide variety of backstops e.g. Pawl and pinch roller backstops developed.
- the disadvantage of all these embodiments is that training close to the winter cannot be simulated with such devices, since the backstop of the ski roller in any case blocks when the skier pushes off. This effect, however, under winter conditions, i.e.
- Snow conditions represent an ideal state, which can only be achieved by a special push-off technique in the diagonal step only after the "search for the pressure point", by a powerful impulse-like imprint at the right time of the motor movement sequence.
- This technique can therefore understandably never be achieved with the training devices of the above Art trained, since with all these devices even the lightest imprint results in an immediate jerky blocking of the backstop.
- Other devices are now trying to avoid this always occurring locking of a wheel.
- the training device described in DE 27 05 253 tries To prevent rolling back during summer training by means of a brake claw, which is arranged in the form of a pendulum support that can be rotated about the rear wheel axis on the ski roller.
- REPLACEMENT LEAF Ski roller only suitable for fitness training.
- the latter two designs are characterized by high wear on brake pads.
- Other designs try to achieve training close to the winter by using a fixed adjustable return brake instead of a backstop.
- Representatives of this group are, for example, the solutions presented in DD 248 245 and DD 248 243.
- the wheel axle is also the inner ring of the backstop.
- the outer ring of the backstop is not non-rotatably arranged on the base of the ski roller, but is connected to it via an adjustable slip clutch.
- the braking torque of the slip clutch is set opposite the outer ring of the backstop.
- a disadvantage of this embodiment is, in addition to the high wear of the brake pads on the slip clutch, the heavy wear of the backstop when skating, since the backstop also takes over the axle bearing in this invention.
- Another embodiment as described for example in DD 273 738, combines a reverse locked on a rear wheel axle with a reverse braked front wheel in order to change the different step techniques, skating and diagonal step during the run without switching on the training device,
- REPLACEMENT LEAF must therefore briefly go into the technique of cross-country skiing. Basically, a distinction is made in the diagonal step technique in cross-country skiing between a sliding phase and a push-off phase.
- alternating phases of the forward movement on cross-country skis in the diagonal step such a ski is "preloaded", that is, the area below the binding "the wax cave” is always so far raised in the gliding phase that it does not cover the snow cover touched.
- the sliding phase the athlete usually stands calmly on both or, according to the step technique, only on one ski and "distributes" his weight evenly over the entire length of the ski.
- ERS ⁇ TZBLA-TT the sequence of movements during skating, especially during the display step, was not taken into account.
- the athlete puts a heavy load on the binding plate of the ski scooter in the deployment step, so that instead of the desired propulsion effect, a braking process is initiated so that in extreme cases even the front wheels can lock up.
- the movement sequence compared to winter cross-country skiing is changed so much that the entire training effect is called into question.
- the brake represents a very high risk of injury in the event of a break in the base of the roller skis, since in this case the sports equipment inevitably blocks and inevitably leads to the athlete falling.
- even small "whirled up" branches or stones can block the braking device, which can cause serious falls, especially at high running speeds.
- a band brake was used as the brake body, which presses two pivotable, spring-loaded wheel brackets when the skier imprints so that the brake band arranged in the base body acts on the brake drum via a tension roller located in the roller body against a tension spring arranged opposite the brake drum and The front wheel set slips depending on the tension of the three tension springs, which are adjusted to the body weight of the skier, and the height of the pushing force of the skier ner rotational movement "backwards" by or if the skier's pushing force is sufficiently large, the front wheel set is blocked, so that the desired push-off effect occurs.
- the present invention is therefore based on the object of developing a light ski roller consisting of a few subassemblies for the summer training of all cross-country skiing techniques, with which the actual imprinting and sliding behavior of cross-country skis both when used to train the diagonal step technique and when using them can be optimally simulated for training the skating technique.
- the ski roller to be developed should be adjustable in such a large range in its impression behavior, even with different body weights and impression forces, that on one hand, with a training device for training the diagonal step technique, the sliding properties of a "pointed" waxed and that of a "blunt waxed” Skis can be set to simulate skiing on different types of snow, but on the other hand, for skating technique training, in addition to adjusting body weight and impression force, different ski preloads should be "simulated", ie can be set, since in winter when performing competitive sports-oriented skiing, a skier with different types of snow needs several skis with different preloads, so that by using this ski roller, optimal summer training as preparation for the
- ski roller according to the invention should be light and ensure a high level of safety for the athlete even under extreme conditions.
- a roller ski consisting of base roller body with a shoe fastening device and two with the base roller body in the end region firmly connected to this wheel axles and a freely rotatable on one of these axes arranged roller or several wheels arranged on this one axis , characterized in that the extensions of the shaft or hub rings of one or more backstops are located on the other of these two axles of the roller ski, freely rotatably, one or more of the rings which are freely rotatable on the axle of the roller roller itself being non-rotatably are connected to the wheels assigned to this roller skate axle or to the associated roller and there is a braking device between the other ring of the above-mentioned backstop (s) and the base roller body.
- REPLACEMENT LEAF turns backwards and the backstop prevents a reverse rotation of the roller, the braking force applied to the above-mentioned brake, depending on its size, brings about a more or less noticeable reduction in the running speed or the stoppage of the roller. This enables a kick similar to skiing, depending on the impression force of the athlete.
- This described backstop and brake combination can be implemented as a combination of a backstop with an "outside” brake, as a combination of a backstop with an "inside” brake and also as a combination of a backstop with an "end” acting brake.
- the roller according to the invention has roller bearings in particular around the side that occurs during skating To be able to absorb forces very well.
- the ski roller base body provided with a shoe fastening device consists of prestressed fiber laminate or fiber laminate composite materials into which one or more mesh-like stabilizing inserts can be introduced and which is preferably designed as a hollow profile, the axle and wheel receptacles arranged at its ends being hollow spherical Half shells are formed, and in / on the base of the ski roller there are deflection limitation, adjustable brake actuation, tensioning and return elements.
- This inventive design of the basic roller body means that in addition to a high resilient behavior of the roller body due to the deflection limiting elements, the deflection of the basic body roller is subject to a limit position, as is the case even in winter conditions when the ski is fully supported on the snow.
- E SAT SHEET Adjustable tension and return elements enable the ski roller to be adjusted to different body weights and the impression force available to the athlete, without having to "try out” a large number of ski rollers for the respective training goal, as is the case with skis.
- the adjustability of the tension and With the solution according to the invention it is possible for the first time to use the ski roller to train the impression technique specific to skating for different types of snow, since this step technique uses skis of different hardness in winter for different types of snow hard pre-tension, which is used especially for hard frozen snow for better ski guidance, "bores" when used in soft wet snow, which greatly reduces the desired high sliding speed.
- this ski roller makes it possible to train the different impression techniques for hard and soft skis in connection with skating on different types of snow even in summer. Due to the universal adjustability, the ski roller according to the invention is also very suitable for the economical use of equipment for training centers, since one device can be driven alternately by different athletes. For the same reason, the ski roller according to the invention is very well suited for use in rental centers.
- the hemispherical shells for the axle and wheel receptacles which are embodied in a spherical shape according to the invention and which are located at the ends of the base of the roller skis, serve as splash protection on a wet roadway. Essential to the invention is further that only between the r
- Impeller axle receiving areas of the roller skate body one or more brake actuation, or brake actuation and deflection limiting elements which are adjustable in their effective length, are arranged, which are directly connected to the braking device mentioned in claim 1.
- any load and relief of the same result in continuous longitudinal displacements of the brake actuation elements which are dependent on the respective instantaneous load on the ski roller base body and its associated deflection. Since, according to the present invention, this is connected directly to the braking device arranged between the base of the ski roller and the pinch roller backstop
- REPLACEMENT LEAF ensures that when pushing off, a defined, depending on the momentary load on the ski roller, braking force acts on the part of the backstop connected to the roller or wheels in a rotationally fixed manner. Due to the adjustability of the effective length of the brake actuation elements, the brake force acting on the backstop and thus the braking torque acting on the wheel can now be varied as a function of the athlete's imprinting force, with the ski roller load remaining constant, ie with constant body weight. This possibility of adjusting the braking force, initially independent of the deflection of the basic body of the roller, has the advantage that the impression behavior of the roller can be individually adapted to each body weight and the impression force available or desired in the athlete.
- this adjustability is favorable for the interchangeability of a training device among several athletes, but it is also optimal for a targeted training for the continuous improvement of the impression technique.
- the adjustment range of the brake actuation elements can be so large in special embodiments that even with full deflection of the ski roller up to the end position limitation there is no longer any braking effect.
- This embodiment of the ski roller according to the invention can then be used on the one hand with a braking effect for training the diagonal step technique, and without a braking effect for training the skating technique.
- REPLACEMENT LEAF can be, without the total weight is increased significantly. It is also essential to the invention that, as in the case of skis, a large number of models for the different body weights and repulsive forces of the skiers are not necessary in order to meet the different training requirements in relation to the pretension and others. Only a few basic models are required in order to reproduce the different properties of the roller skis that are necessary for different body weights and with minimal weight by replacing or adjusting the spring-elastic adjusting elements or tension springs for the planned training goal (e.g. pointed or blunt waxed skis) .
- the planned training goal e.g. pointed or blunt waxed skis
- the solution according to the invention also makes it possible, for example, for ski scooters which e.g. only to be used for roller skating races in the skating style, in order to save weight, to omit the spring-elastic adjusting elements or tension springs as well as the backstop / return braking system in order to then tailor the required pretension to the respective athlete through the appropriate design of the fiber laminate or the fiber laminate composite materials.
- FIG. 1 shows a ski roller consisting of a base body 1 with the axle and wheel receptacles 2 arranged in its end regions, in the form of hemispherical half-shells, and the rear roller 5 fastened therein by means of a rear wheel axle 4 and the front roller 7 fastened by means of a front wheel axle 6 , as well as the shoe fastening device 3 arranged on the ski roller base body 1.

- REPLACEMENT LEAF Adjusting element 11 can be varied.
- a further tensioning rope is arranged in the base of the ski roller as a deflection limiting element 13. This also runs in an arc in a guide strand approximately at the level of the “neutral fiber” of the base of the roller skier from an attachment point in the
- Impeller axle receiving area of the rear wheel to a fastening point in the impeller axle receiving area of the front wheel.
- FIGs 3 and 4 a possible design of the front wheel set, the ski roller just described, is shown in section.
- the front wheel axle 6 is screwed into the front axle and wheel receiving shell 2 by means of two axle fastening screws 14.
- an eccentric shaft 15 is rotatably arranged, which is connected on both sides to a brake actuation lever 8 in a rotationally fixed manner.
- the hub extensions 18 of the outer ring of a pinch roller backstop 19 are now freely rotatably supported on both sides by means of two roller bearings 20, and thus the front roller 7 connected to it in a rotationally fixed manner.
- the eccentric shaft 15 with cylindrical rolling elements and with a split brake ring 16 which delimits them to the outside is arranged centrally between the roller bearings 20 just described.
- the inner ring of a pinch roller backstop 17 runs on the outer jacket of this brake ring.

- the rolling elements of the pinch roller backstop roll on the inner ring of the pinch roller backstop 17.
- the extension 18 of the hub of the outer ring of a pinch roller backstop 19 and thus the front roller 7, which is connected to this in a rotationally fixed manner, is now freely rotatably supported on both sides by means of two roller bearings.
- the front roller 7 rotates and takes the components connected to it in a rotationally fixed manner, such as the outer rings of the roller bearings 20 and the outer ring of the pinch roller backstop 19.
- the rolling elements roll - as with the design described above.
- the pinch roller backstop on the inner ring of the pinch roller backstop 17.
- these rolling elements jam between the outer ring 19 and the inner ring 17 of the pinch roller backstop and thus take the inner ring with them without slippage.
- the brake band 22 shown in FIG. 6 is pressed against the circumference of the brake drum 21 by tensile load on the brake actuating element 10, the front wheel set becomes dependent on the resulting “Eytelwein's” rope friction
- the ski roller By adjusting the tensioning and return element 9, the ski roller is adapted to the body weight of the athlete and the sliding - climbing behavior, "pointed” or “blunt waxed” of the simulated ski.
- the repulsion to be applied by the athlete at the moment of repulsion, ie the pressing force of the brake band 22 is set by means of the adjusting nuts 23.

- the brake actuating levers 8, each provided with a front eccentric 25, also lie symmetrically to the center axis of the roller skis on these brake disks 24.
- the two end eccentrics 25 of the brake actuation levers 8 are paired with an associated end eccentric disk 26, which are pressed between the axle and wheel receiving shell 2 and the brake actuation lever 8 on both sides by the axle fastening screws 14 to the end faces of the front wheel axle 6. To prevent rotation, this end eccentric disk 26 is pinned to the axle and wheel receiving shell 2 by means of a pin 27. If the brake actuation lever 8 is now rotated, the end eccentric of the brake actuation lever 8 slides along the end eccentric disk 26. This leads to a horizontal displacement of the two brake actuating levers 8 along the front wheel axis 6 in the direction of the center of the wheel.
- the two brake actuation levers 8 are pressed with their braking surfaces 28 against the associated braking surfaces 28 of the brake disks 24, and so the roller 7, in conjunction with the backstop in engagement, is braked.

- an exchangeable tension spring 29, which is included in the sales packaging in different hardnesses is inserted into the assembly tensioning and return element 9.
- FIG. 10 shows a further constructional variant of the basic body of the ski roller.
- Stabilizing inserts 31 and 32 are attached in or on the fiber laminate hollow body. In particular, these prevent the carbon laminate hollow body from breaking in the event of an impact, for example due to unintentional side impact or in the event of a fall.
- the stabilizing inserts 31 and 32 can preferably also consist of a mesh-like steel wire mesh. When storing a stabilizing insert with longitudinal elements 31 in the fiber laminate, this also causes an increase in the longitudinal elasticity.
- a stabilizing insert with diagonally directed elements 32 increases the torsional rigidity.
- FIG. 9 An alternative embodiment to FIG. 7 is shown in FIG. 9.
- the backstop is arranged on the extension of the shaft ring 18 and at the same time forms the inner ring of the pinch roller backstop 17.
