Description

The invention relates to a training or sports equipment, in particular for carrying out a vibration training u. a. for the development of muscle and bone tissue and against existing or for prophylaxis in anticipated bone and / or muscle wasting of the human body.

There are numerous scientific studies on the mode of action and the effects of vibration training, with results that are sometimes still contradictory. However, it has been found that vibrations of a frequency range of preferably 5 Hz to 30 Hz, for certain applications of several hundred hertz reflexes or direct reaction of the tissue are triggered, the Cause muscle contractions. These reflex-conditioned muscle contractions train the performance of the musculature and, in addition, can indirectly counteract bone loss when properly applied by building the musculature; at other frequencies of vibration, an increase in bone density is directly stimulated. A variety of other effects of vibration training is known: increased tissue perfusion, improved balance or body control, mobilization of joints, reduction of stress incontinence by toning the pelvic floor muscles, improvement of chronic back pain.

In the previously known exercise equipment, the person to be treated is preferably on a vibrating plate, which is then excited to oscillate in the desired frequency range. This means, as a result, that persons who wish to undergo vibration training need such a device, in the application of which the body otherwise remains in a passive role.

US 5909889 discloses a Fohnad with such vibration training.

Proceeding from this, the present invention seeks to provide a training or sports equipment of the type mentioned above, on the one hand allows the exercise of a conventional sporting activity and beyond the possibility of vibration training also allows.

This object is achieved according to the invention by the characterizing parts of claims 1, 3, 9, 12, 13.

The advantage achieved by the invention consists, first of all, in the fact that the effect of a - generally speaking - physical exercise, which is aimed at by the use of the conventional training or sports equipment, is superimposed by the effects of vibration training, which has a synergistic effect, in particular with regard to loosening the muscle tissue. a better circulation of the same as well as a muscle building can be expected. The result is an aerobic sport associated with a more anaerobic vibration training, so a simultaneous cardiopulmonary training and vibration training possible.

In any case, the positive effects of vibration training can contribute to a reduction of the accident risk in accident-prone training or sports equipment, since the effects of vibration training - such as better blood circulation in the muscles - can at least minimize body-related accident risks.

Finally, as a rule, the apparatus required for the vibration training is lower because the energy required for this is applied directly by the trainee himself, so additional motor drives or the like are not needed.

In any embodiment of the invention, it is advantageous if one or more rollers are provided for the movement sequence and the kinematic transducer is in operative connection with the roller (s).

Such a configuration may preferably find application in training or sports equipment in the form of skates, inline skaters, a bicycle or stationary ergometer, a rollator or wheelchair, a seat in a rowing boat or an exercise bike, pulleys working with weights training equipment, treadmills or a similar device containing a rolling motion.

For the design of the kinematic transducers, there are a variety of different design options according to the particular application; According to a first advantageous development of the invention, the kinematic transducer can be formed by the axle bearing element of the roller, wherein the axle bearing element is arranged eccentrically to the roller. As a result, a vibration movement is achieved in accordance with the rotational speed of the roller.

In order to be able to influence the vibration stroke, the invention provides that the eccentricity of the axle bearing element is adjustable.

In addition to this rigid coupling of the vibratory motion with the circulation of the roller, according to a further embodiment of the invention, the kinematic transducer can be formed in the manner of the axle bearing element of the roller that the axle bearing element against at least one Spring element is deflected from its centric position to the roller. As a result, a certain damping of the vibration movement is achieved by the way. It is recommended here, if the force of the spring element is adjustable.

In this case, there is also the possibility that the axle bearing element can be deflected in one or more radial directions of the roller. As a result, an increased vibration frequency can be achieved at the same rotational speed of the roller.

The spring element may be formed in a conventional manner; In the context of the invention, it has proved to be advantageous if the spring element is designed as a helical spring or as an elastic Pufferelment. Here, too, it is advantageous if the vibration stroke of the axle bearing element is switched on and lockable.

According to a further embodiment of the invention can also be provided that the kinematic transducer is formed by the axle bearing element of the roller, the axle bearing element is provided with an outer ring gear and eccentrically mounted, while the roller runs with an internal ring gear on the outer ring gear of Achslagerelements. In order to achieve a variation of the vibration frequency here, the ratio of the two sprockets can be made changeable. In principle, the vibrations can also be generated via a planetary gear, whereby even more complex waveforms can be achieved. This allowed, for example, alternating Generate frequencies or amplitudes.

Another way to superimpose a vibration frequency training or sports equipment, can be realized that the kinematic transducer is formed by an inhomogeneous mass distribution in the role. This can be done according to a first embodiment characterized in that the inhomogeneous mass distribution is formed by a firmly embedded in the roll unbalanced body with respect to the role significantly higher specific gravity and where the unbalanced body radially opposing areas of reduced specific gravity preferably in the form of recesses in the role are provided.

However, instead of a static arrangement of such an imbalance body, there is also the possibility that the inhomogeneous mass distribution is formed by the imbalance bodies movably arranged in the roller. For this purpose, the unbalanced body can be arranged for example in tubular channels of the roll.

Depending on the desired vibration effect, these tubular channels can be arranged wave-shaped, elliptical or in a similar configuration about the axis of rotation of the roller, so that an influence on the movement sequence of the unbalanced body and thus as a result of the vibration vibrations can be achieved. For this purpose, it can also be provided that the tubular channels are provided with profiled walls, via which a further influence of the Vibrational movements can be achieved.

The imbalance body can be formed within the scope of the invention, for example, balls of the same or different density, granules, liquid, gel or the like.

A further embodiment of the invention is characterized in that the roller has a plurality of uniformly or non-uniformly distributed over the circumference, elastically deformable lamellae which connect the roller axis with the roller tread. As far as the roller tread here has a corresponding elasticity, this leads depending on the formation of the lamellae to a deformation of the roller tread and thus in turn to a vibratory movement and wherein the lamellae along the circumference may have a different degree of elasticity and / or different degree of curvature.

In addition, there is the possibility that the space between the slats is hollow or filled with plastic or gel, which in turn leads to a further influence on the achievable vibration stroke. Furthermore, the slats can also be interconnected by spring elements.

A further advantageous embodiment of the invention provides that the axis of the roller is pivotally suspended resiliently and the roller is provided with edge-side recesses in the region of its tread.

This makes it possible to vary the orientation of the roller to its drainage surface and to achieve a variation of the vibratory motion through the different, coming into contact with the ground areas of the tread and when driving on an irregularly shaped ground generated vibrations with adverse effect, at least partially to reduce or filter out.

Regardless of this, however, there is also the possibility of providing the roller with a profiling on its tread, by means of which the vibration movement is directly achieved. In order to have variability possibilities here as well, the profiling in the longitudinal direction of its running surface can have a different density and / or a different profiling depth transversely to the running direction. As a result, vibration waves in different levels can be achieved (see also drawings). Further variations can be achieved by the integration of inflatable elements, which could possibly be influenced by the movement of the user himself: For example, the degree of hardness of the roll or the tread depth could change depending on the rotational speed (or the roll inclination).

Finally, there is still the possibility of an integration of piezoelectric elements, by which additional effects in the manner of a superimposition could be achieved in addition to the vibrations generated by the muscular force of the user for certain target groups.

In addition, it should be noted that the possible simultaneous application of some of the vibrational vibration techniques described herein may be used to generate multiple superimposed vibration waves of different frequency and amplitude, thereby allowing multiple organ systems to be simultaneously stimulated (for bone grafts). and muscle tissues, for example, different vibrational frequencies are required to stimulate growth).

Depending on the choice of the superimposed vibration waves, a beating effect can also be generated, with beats with a clearly defined frequency of beating being preferred in the sense of a positive therapeutic effect.

Finally, in order to be able to generate oscillations or vibrations with relatively little energy expenditure, it is finally possible to consider taking measures which lead to a "rocking" of a vibration wave. This could be achieved by a suitable coupling with spring elements and / or shock absorbers or by exploiting the natural frequency of the overall system.

That in the drawing in Fig. 1 exemplified training or sports equipment, here in the form of an in-line skater with a boot 1 and rollers 2, used in the manner shown here as a device for recreational activity with the side effect of a general physical exercise.

In order to be able to additionally carry out a vibration training in the application of such a training or sports equipment, in particular against existing or for prophylaxis in anticipated bone and / or Muscle wasting on the human body recommends, the invention provides that the exercise or sports equipment is provided with one or more kinematic transducers, which generate a vibratory motion of the preferably applied by muscular strength of the trainees kinetic energy. In particular, these serve in detail in the Fig. 2-10 shown rollers 2, with which the kinematic transducer is in operative connection. Thus, the use of the invention is by no means according to inline skaters Fig. 1 limited; Rather, an application is generally possible even with roller skates, bicycles or bicycle ergometers as well as walkers or wheelchairs. Basically, all devices are suitable that perform a sequence of movements on rollers 2, as is the case, for example, the rolling seat of a rowing boat or a home trainer.

In a first embodiment according to FIG. 2 the kinematic transducer can be formed by the axle bearing element 3 of the roller 2, the axle bearing element 3 being arranged eccentrically to the roller 2. In the illustration after Fig. 2 the eccentricity is fixed; however, it is also possible to make this eccentricity adjustable.

An adjustability of the eccentricity is, for example, in the embodiment of the Fig. 3 and 4 given here, in which case the kinematic transducer is formed by the axle bearing element 3 of the roller 2 and the axle bearing element 3 is deflectable against a spring element 4 from its centric position to the roller 2. Depending on the rotational position of the roller 2 takes place here a deflection from the central position, resulting in the rotational movement of the wheel 2, a vibrating motion. The force of the spring element 4 can also be adjustable in a manner not shown. In a manner not shown in more detail, the axle bearing element 3 may also be deflectable in one or more radial directions of the roller 2.

In the embodiment according to Fig. 3 the spring element 4 is formed by a helical spring; in Fig. 4 For this purpose, an elastic buffer element is provided.

Also, there is also the possibility not shown here that the vibration stroke of the axle bearing element 3 is switched on and lockable.

In another, not shown in the drawing embodiment, the kinematic transducer can be formed by the Achslagerelement 3 of the roller 2, wherein the Achslagerelement 3 is provided with an outer ring gear and is mounted eccentrically. The roller 2 then runs on this outer ring gear with a corresponding inner ring gear, which also results in a vibration stroke due to the eccentric arrangement of the Achslagerelementes 3. The vibration frequency can be changed via the transmission ratio of the two sprockets.

Another embodiment is in Fig. 5 Here is the kinematic transducer of an inhomogeneous mass distribution 5.6 in the role of the second educated. As is clear from the Fig. 5 Furthermore, the inhomogeneous mass distribution 5.6 is formed by a firmly embedded in the roll unbalanced body 5 with respect to the roller 2 significantly higher specific gravity. In order to increase this effect, the imbalance body 5 can be provided radially opposite a region 6, which has a reduced specific weight, for which a recess in the roll 2 is offered in the simplest way.

However, there is also the possibility of creating the inhomogeneous mass distribution by means of unbalanced body 5 movably arranged in the roller, which may result in additional dynamic effects. This is in several variations in Fig. 7 shown. For this purpose, the unbalanced body 5 may be arranged, for example, in tubular channels 7 of the roller, wherein the tubular channels 7 may be arranged wave-shaped, elliptical or in a similar configuration about the axis of rotation of the roller 2. There is also the possibility of providing these tubular channels with a profiled wall.

The unbalanced body 5 can be formed by balls of the same or different density; However, other materials are also suitable for this purpose, such as granules, a liquid, gel or the like.

In Fig. 8 Further embodiments of movably suspended or mounted imbalance bodies 5 are shown, which are connected thereto at the center of the axle and / or on the running surface via spring elements 8 can. The unbalanced body 5 are in turn arranged in radially extending channels 7, whereby the possibility exists, a channel 7 conically widening form, whereby additional, overlapping vibration movements can be generated.

In Fig. 9 a further embodiment variant is shown in which the roller 2 has a plurality of evenly or non-uniformly distributed over the circumference arranged lamellae 9, which are elastically deformable and connect the roller shaft 10 with the roller tread. These lamellae 9 may have a different degree of elasticity and / or different degree of curvature along the circumference and allow a deformation of the tread 11 of the roller 2, resulting in a kind of "wobbling" elastic tire. This will deform elliptically under load and give rise to vibration vibrations.

The space between these lamellae can either be hollow or else be filled with plastic or gel. Likewise, there is the possibility indicated in the drawing that the slats are interconnected via spring elements 12 with each other.

In FIG. 10 Finally, another embodiment is reproduced, in which the axis 10 of the roller 2 is pivotally suspended resiliently. The roller 2 is in this case provided with edge-side recesses 13 in the region of its tread 11, as a result of which vibrations in another plane can be generated.

Finally, the role can also - as in Fig. 6 is shown - be provided on its tread 11 directly with a profiling, whereby an eccentric storage is eliminated. This profiling may have a different density and / or a different profiling depth transversely to the running direction in the longitudinal direction of its running surface 11.
