    Portable sports device The invention relates to a portable sports device and in particular training device for building muscle with at least one handle and an operatively connected therewith, mounted on a shaft flywheel, which is set in rotation by the pulling on a shaft attached to the rope and wound thereon and can be slowed down again. The force to be applied for this purpose can be adjusted by at least one removable mass additive element arranged on the flywheel mass.
    DE 10 2011 105 609 A1 describes such a sports equipment. It has two handles, which are connected by a pull rope. One end of this pull rope is wound on a shaft mounted on one of the two handles, which also serves as a bearing for a flywheel and in particular flywheels. By pulling on the pull rope or a movement of the handles away from each other, the pull rope wound on the shaft can be unrolled and so the flywheel can be set in rotation. Once the pull rope is completely unwound from the shaft, it is rewound on the shaft in the reverse direction due to the rotation of the flywheels until the handles are pulled apart again or the pull rope is completely wound up. In order to keep the flywheels continuously in rotation and counter rotation, therefore, an operator of the sports equipment constantly changing between load and discharge is required. This leads to a very beneficial training effect. To vary the training effort, mass additives can be applied in the form of magnets on the flywheels. Depending on the size and mass of the mass additive element so the total mass of the flywheel can be changed and the training effort can be adjusted. With the total mass of the flywheel increases their inertia, resulting in increased effort for the user both when accelerating, as well as braking the flywheel. The total mass of the flywheel thus contributes significantly to the training effort and is particularly appropriate to increase the effort by additional attachment of additional mass elements. A user can thus, for example, begin training without additional mass elements and increase the total mass when the training success is achieved.
    It has been shown that the handling of sports equipment of the prior art, in particular with respect to the adaptation of the training effort by mass additives to the flywheels, uncomfortable for the user in the long term, resulting in reduced exercise motivation and thus reduced training success. In addition, due to the mass addition elements occasionally occurred imbalances in the rotation of the flywheel, which were perceived by the user as unpleasant.
    Object of the present invention is therefore to provide ways in which sports equipment of the aforementioned type can be improved. In particular, it is the object of the invention to improve the handling of a sports device of the aforementioned type in general and in particular with regard to the adaptation of the training effort such that the sports equipment are used regularly and with increased training success.
    This object is achieved by an initially mentioned portable sports equipment and in particular a training device in which the at least one mass additive element is designed in the form of a circular ring piece or a circular segment piece.
    The invention has the advantage that it is possible to offer different mass additive elements, which differ in particular in their mass to achieve several adjustment levels. So as soon as a user wants to increase the training effort even further, he can replace his previous mass additive elements with even heavier mass additives. The mass additives are applied directly to the flywheel and preferably fixed by screwing to this. For this purpose, corresponding bores are provided both in the flywheel masses and in the additional mass elements, through which the screws are guided. However, it is also possible to attach the mass additive elements in other ways to the flywheel masses, for example by clamping. The advantage of the invention is that the mass additive elements are releasably secured to the flywheel so that they can quickly and easily on the flywheel and can be degraded again by her.
    According to the invention, the at least one mass additive element in the form of a circular section piece or circular ring piece. Both forms in the context of the invention designate a three-dimensional body having two sides, each having the shape of a circular section or a circular ring piece. These surfaces are suitably opaque one above the other, so that the mass additive then has a rectangular shape in cross-section, whose height corresponds to the thickness of the mass additive element. The mass additive element is preferably solid, expediently made of metal, but may also have recesses or be composed of a plurality of materials, for example plastic and metal. The terms Kreisringstück and circular ring sector are to be regarded as synonymous within the meaning of the invention. Likewise, the terms circular segment and segment of circle segments are to be regarded as synonymous.
    The formation of the mass additive element as a circular segment piece or circular ring piece has the advantage that a user in the attachment of the mass additive element usually formed as a flywheel flywheel can recognize directly on the shape of the mass additive element, in which orientation it will be attached to the flywheel should. The annular or kreisabschnittför shaped mass additive preferably follows in its shape the outer periphery of the flywheel so that it can be flush with the outer edge of the flywheel attached to this. On the outer circumference of the flywheel higher centrifugal forces act on the flywheel or the mass additive element. At the same time, the inertia caused by the spacing from the axis of rotation causes higher leverage forces on the shaft which lead to the desired increased effort in accelerating and decelerating the flywheel by a trained user. In addition, the shape of the at least one mass additive element causes a more uniform rotation of the flywheel and thus reduces imbalances in operation.
    In order to achieve a particularly uniform rotation of the flywheel and thus a uniform force development on the traction cable over the shaft, it is advantageous if a plurality of mass additive elements are present, which are mounted to each other so that they are distributed as symmetrically as possible in the outer edge region of the flywheel For example, form a continuous circular ring on the flywheel. As a result of this design, the centrifugal forces acting on the mass additive elements act symmetrically outwardly from the flywheel mass, as a result of which the rotation of the flywheel mass is not adversely affected by unilaterally acting forces. The flywheel rotates so particularly calm and balanced, whereby tilting forces are avoided. As a result, an unfavorable burden on the user is prevented, and the comfort and manageability of the sports equipment are increased.
    This embodiment is particularly simple if two additional mass elements are present, which are formed as semicircular rings. Both arranged on the flywheel mass additive elements together thus form a complete annulus. The two semicircular rings are in each case directly adjacent to each other with two surfaces on which the circular ring is halved. Since the mass accessories must be arranged around the shaft, an embodiment as a component, at least when a complete annulus is sought, impossible without removing the shaft from the housing. The design of the mass accessories as two semicircular rings makes it possible to install them on the flywheel without having to remove the shaft. At the same time, the simple construction of only two parts of the mass additive prevents the mass additive elements from being incorrectly arranged on the flywheel and thus ensures a faultless function of the sports device.
    A further preferred embodiment is that there are two mass additive elements which are formed as circular section pieces. These circular section pieces are fixed directly opposite to the flywheel, so that their centrifugal forces arising during the rotation of the flywheel balance each other. The two Kreisab cut pieces are spaced from each other and mounted on the flywheel from the shaft, so that between them enough space for arranged on the shaft coupling elements is released. In a preferred embodiment, the outer radius of the circular section pieces is flush with the outer radius of the flywheels.
    To adjust its mass and thus the force required in the movement of the flywheel, the at least one mass additive element with respect to its surface area and / or thickness can be varied. In the former case, a variation is basically possible both in the circumferential direction and in the radial direction. Also on the number of mass additives used, the force can be adjusted specifically. In the preferred pairwise use of circular section pieces or circular ring pieces, which cover the outer circumference of the flywheel completely or almost completely, a variation of the extent in the circumferential direction virtually eliminates, so that in these cases only a change in the mass additive elements with respect to their thickness and their extension remain in the radial direction. However, it is still possible to attach several mass additive elements of comparatively small thickness one above the other and thus to change the number of mass additive elements. Preferably, the portable sports device according to the invention comprises as a set a number of mass additive elements that can be combined with each other and / or used interchangeable to set the force required for the rotation of the flywheel force.
    The installation of the mass additives by a user can be facilitated by the fact that a stop is present, to which the at least one mass additive element strikes. The stop may in principle be aligned both in the radial direction, which is particularly preferred, as well as in the circumferential direction of the flywheel and facilitates the alignment of the mass additive element in a position in which it is to be attached, for example by screwing, to the flywheel. The stop may be located on the flywheel and / or the at least one mass additive element. For example, may be present on the mass additive element, a projection which is designed so that it abuts against the end face of the flywheel or engages in a recess on the flywheel, when the mass additive element is arranged on the flywheel. Alternatively, the stop can be produced by forming an annular depression open towards the edge of the flywheel mass in the outer peripheral region of the flywheel, the inner edge of the depression concentric with the outer circumference then forming the stop against which an annular mass additive element abuts when in the recess is inserted. The flywheel is thus closer to the shaft thicker than at its outer periphery and has between thicker and thinner area on a concentric to its outer periphery extending stage. In this embodiment, another advantage of the embodiment of the
    Mass additive elements as two half-rings to carry: By embracing the circular stage of the flywheel by one of the half-rings, which abuts with its inner periphery of the stop, the stop prevents movement of the mass additive element in two directions. On the one hand to the axis of rotation and the other transverse to this direction along the contact surfaces of the half-ring for the second half-ring.
    In order to realize the most compact design of the sports equipment, it is important that the mass additives are as small as possible, so that the housing of the sports equipment must not be excessively large in order to accommodate the mass additives can. Although it is in principle possible to form the mass additive elements in various forms, for example, on the plant side, which is directed to the flywheel, flat and rounded on the other side. However, it is preferred if the at least one mass additive element has a substantially rectangular cross-section. The at least one additional mass element thus has two flat sides, which are connected by end faces, wherein the end faces are arranged substantially at right angles to both flat sides. This embodiment has relatively much mass at a relatively small maximum height or relatively small maximum thickness of the mass additives and is also particularly easy to produce.
    In principle, it is advantageous to provide the sports equipment with a housing which surrounds the flywheel at least partially. On the one hand, the visual appearance of the sports equipment can be designed so freely, and on the other hand, safety risks can be avoided, which emanate from the rotating flywheel masses. However, a problem with a housing is that it normally has to be removed or opened for attaching or removing ground additives to the flywheel. This removal or opening of the housing is an additional step, which is perceived as disturbing in the training process. To prevent this, is provided in an advantageous embodiment of the sports equipment that a housing is present, which surrounds the flywheel at least partially, but at least one opening through which the at least one mass additive element can be arranged on the flywheel or removed from it , The opening in the housing must therefore be dimensioned sufficiently large in order to move the mass additives through them can. The attachment of the mass additives to the flywheel is carried by the at least one opening therethrough. For this purpose, even a single opening is sufficient, since the flywheel can be aligned by turning so to the opening that the attachment position for each mass additive element is located below the opening. It may of course be present for each additional mass element in the housing, a separate opening. In any case, however, an opening of the housing is no longer necessary for the assembly or disassembly of the mass additives.
    A particularly advantageous development of all embodiments consists in the formation of the flywheel as spoked wheel. In the simplest case, a spoked wheel according to the invention is formed by recesses in the disk area of the flywheel. The term "spoked wheel" should therefore also be understood to mean those configurations in which the mass of a flywheel is generally reduced by openings of all possible shapes in the radial direction closer to the shaft with respect to the outer peripheral region. But this also means a spoked wheel with separate spokes between hub and outer circumference. The basic idea here is to distribute the flywheel mass so that it is smaller near the shaft than in the area of the outer circumference. This is also achieved by a spoked wheel, in which the hub is connected via a wreath spokes with an outer ring, which makes up the bulk of the mass of the spoked wheel. The advantage is that further from the axis of rotation removed mass exerts a greater inertial force on the shaft than located closer to the axis of rotation mass. When more mass is removed from the axis of rotation, the flywheel itself, especially in the area immediately around the shaft, can be made lighter. At the same expended force of a user can thus be reduced by the spoked wheel, the total weight of the sports equipment. If a user needs to exert less force to simply hold the sports equipment, he can concentrate his power advantageously on the exercises and movements with the device. Practicing is more enjoyable and effective.
    Also in this direction going and advantageous for all embodiments of the invention, it is when the frame member on which the shaft supports, consists of solid material in which at least one recess is present for weight reduction. A suitable solid material for the frame member is, for example, a light metal such as aluminum or a light metal alloy such as an aluminum-magnesium alloy. These are characterized by special strength and low weight. By the at least one recess in the frame element, the total weight of the sports equipment is further reduced. The at least one recess is advantageously located in a region which is covered by the housing of a handle shell in the completely assembled sports device, so that it is not visible from the outside. In addition, the at least one recess is expediently arranged where no high mechanical loads act, so that the stability of the frame element is not reduced. Taking these aspects into account as much as possible recesses are provided in order to achieve the lowest possible total weight.
    The area in which the traction cable of the sports equipment wound by rotation of the shaft on this, is referred to as Aufwickelbereich the shaft. It is preferred that the pull rope winds as evenly as possible over the take-up area without forming thickened areas or knots. Such thickened areas can lead to uneven or even abrupt strain on the user. In order to prevent the formation of coils during winding of the pull rope, it is preferred that on each side of the take-up area there is provided as each end a turn-up jaw having a concave surface directed towards the take-up area. When the traction cable abuts the concave surface during winding, the traction cable rotates and winds further towards the shaft in the direction away from the transferring jaw. When abutting the pull cable to the concave surface, the next winding not only above, but also lies further inwards from the previous winding. The concave surface thus gives the pull rope a quasi impulse in the changed running direction and thus prevents a ball formation in the area of the change of direction. So a regular winding and a quiet running of the sports equipment is achieved. The concave surface may be conical or frusto-conical or, preferably, dome-shaped.
    To further increase the ease of use of the sports equipment, it is preferred that the attached to the shaft end of the traction cable opposite free end of the traction cable via a spring, in particular a steel spring, is stored damped on sports equipment. By the spring in particular jerky movements of the traction cable against the frame element of the sports equipment are damped and thus not transmitted to the user via the handles. So that the spring can not tilt, it is preferably mounted within a cylinder on the frame member, which serves as a guide for the spring and the free end of the pull rope. The cylinder can also be closed by a cap or a lid. In addition to an increase in comfort and shock loads of the traction cable and the frame element are weakened in itself, whereby the life of the sports equipment is extended.
    In order to transport the sports equipment easy, a parking brake is preferably present. By means of this parking brake, the flywheel or the shaft can be locked, so that the rope can not roll up or roll off by itself. For example, the sports equipment can be safely transported in a suitcase or bag. In a particularly simple form, the parking brake comprises a biased by a spring pin, which engages by the spring bias in a recess on the flywheel. The recess is, for example, a notch in the outer end edge of the flywheel, in which the pin of the parking brake can engage. Preferably, several such recesses are distributed in the outer edge of the flywheel, so that the flywheel does not have to be rotated far until the
    Engages the parking brake pin in one of the recesses. Due to the bias, the pin automatically engages in one of the recesses when the parking brake is actuated by the operator and prevents the flywheel from continuing to rotate. The parking brake is released by the operator by moving the pin against the latching direction and against the spring tension. In this position, the parking brake can be locked so that it does not accidentally in use when using the sports equipment in action.
    In the following the invention will be further described by means of embodiments, which are illustrated in the drawings. Here are shown schematically:

    6 shows a detailed view of a shaft with handling jaws;
    Fig. 7 is a detail view of a parking brake and
    Fig. 8 shows the sports equipment of Fig. 1 with a closed housing.
    The sports equipment 1 of Figures 1 and 8 comprises a first device part 2 and a second device part 4, on each of which a handle 6, 9 is provided. With the handle 6 of the first sports equipment part 2 is mounted on a shaft 8 flywheel 10, 10 'in operative connection, which consists of two spaced apart and centrally positioned on the shaft 8 flywheels 11,11' consists.
    The shaft 8 is mounted in a frame member 5, which is made of solid material, such as an aluminum-magnesium alloy or an aluminum alloy. On the frame member 5, the handle 6 is integrally formed. In this case, the shaft 8 is rotatably positioned in the frame member 5, that the axis of rotation AR is parallel to the main extension axis Ah of the handle 6. In the frame member 5 recesses 102 are provided which are intended to reduce the overall weight of the sports equipment. By way of example, possible positions of the recesses 102 are shown by dashed lines. For the positio NEN of the recesses 102 is only important that they do not reduce the stability of the frame member 5 too much and that they are covered by the housing 13 and the handles 114, 114 '(Figure 8).
    In between the two flywheels 11, 11 'of the flywheel 10, 10' formed space 21 is a part 3 of the frame member 5 is inserted so that a handle grip 23 forms, which encompasses both the gripping of the handle 6 with one hand also allows the insertion of a foot and in particular a Ristes a foot for certain training methods.
    In the area of the free space 21, a winding area 104 is formed along the shaft 8, in which the traction cable 12 extending between the two equipment parts 2 and 4 can be wound up. For this purpose, the traction cable 12 is attached with a free end to the shaft 8 (hidden under the winding) and positioned so that it is wound in a rotation of the shaft 8 about its axis of rotation AR in the winding area 104.
    As shown, the traction cable extends from the shaft 8 to the second sports device part 4 and the handle 9, where it is deflected at a deflecting element 46 and returned to the first sports equipment part 2. There it is fixed to the frame member 5 with its second free end 27. In order to dampen particular kickbacks at voltage peaks within the traction cable 12, the second free end 27 is fixed with the interposition of a damping element 29 on the frame member 5. The damping element 29 is in the illustrated embodiment, a spring, such as a steel spring. This is arranged to guide within a tube or cylinder 30 (indicated in Figure 1). The tube or cylinder 30 is closed with a cap 30 ', for example a plastic cap. By this arrangement of the spring sudden high tensile forces on the pull rope 12 can be compensated, at the same time a hooking or tangling of the pull rope or the spring by the cylinder 30 and the cap 30 'is prevented.
    In order to ensure a safe guidance of the traction cable 12, in particular with decreasing train between the two parts of the device 2, 4, guide elements 31, 31 'are provided on the frame element, via which the traction cable 12 can be guided through the frame element 5.
    The traction cable is so in operative connection with the shaft 8 and the flywheels 11, 11 'coupled thereto, that it is unwound from the shaft 8 during application of a tensile force, for example by oppositely directed train on both handles 4, 6. Simultaneously with this rolling movement, there is an acceleration of the shaft 8 and the flywheel 10, 10 'or flywheels 11, 1T arranged thereon. As soon as the traction cable 12 is completely unrolled from the shaft 8, the rotational movement of the shaft 8 or the flywheel 10, 10 'continues as a result of the inertia, so that the traction cable 12 is wound up again on the shaft 8 in the reverse order. Shortly before the traction cable 12 is then completely wound up on the shaft, the rotation of the shaft 8 can be stopped by active train on the two handles 4, 6. This occurring voltage peaks are removed in part by the damping element 29. The rest of the removal takes place in part by overcoming a static friction between the flywheel 10, 10 ', the shaft 8 and intermediate coupling elements 14,14', which are designed as a slip clutch.
    In Figure 1, an optional mass additive 101 is indicated by dashed lines on the flywheel 1T. Such mass additives 101 are mounted on both flywheels 11, 1T, even if the example here refers to the flywheel 11 '. FIG. 2 shows a cross section through a flywheel 10 'or flywheel 11' with mass additive 101 arranged thereon, which, as shown in FIGS. 3 and 4, is composed of two mass additive elements 110, 110 ', 115, 115' designed as semicircular rings or circular segment pieces ,
    The semicircular rings 110, 110 'of Figure 3 are assembled into a circular ring that they touch on their contact surfaces 113, 113'. Inside the annulus there is a recess 112 through which the shaft 8 is guided and which is also large enough to receive the coupling elements 14, 14 '. Preferably, the mass additive 101 is also spaced from the coupling elements 14, 14 'by the recess 112, so that the mass of the mass additive 101 is further away from the axis of rotation Ar. The fastening of the semicircular rings 110, 110 'on the flywheel 11, 11' takes place by means of screw connections 111 which run parallel to the shaft 8.
    The circular section pieces 115, 115 'of Figure 4 are spaced apart with their straight sides on the flywheels 11, 11', wherein the straight sides are parallel to each other. They are therefore exactly opposite and spaced from each other and from the shaft 8 on the flywheels 11, 11 '. The distance D is chosen so that sufficient space for the coupling elements 14, 14 'remains. Their respective outer radius is flush with the outer radius of the flywheels 11, 11 '. The mass of the circular section pieces 115, 115 'is thus also removed from the axis of rotation Ar. The attachment takes place as in the semicircular rings 110,110 '.
    As shown in Figure 2, the semicircular rings 110, 110 'and the circular section pieces 115, 115' have a substantially rectangular cross-section. The flywheel 11 'has an inner region Q and a mass attachment region P, wherein the mass approach region P relative to the radius of rotation R is farther from the rotation axis AR or the shaft passage opening 103 than the inner region Q. The mass approach region P is less thick than the inner region Q and adapted to receive the mass additive 101. In this area of the flywheels 11, 11 'are thus the holes for the screw 111. When the mass additive 101 is disposed on the mass approach area P, the thickness of the mass additive 101 and that of the flywheel 11, 11' in the mass approach area P taken together are greater than that Thickness of the flywheel 11, 11 'in the inner area Q. This has the advantage of the already described effects of the displacement of the mass away from the axis of rotation AR. Furthermore, the flywheel 11, 11 'at the transition from mass approach area P to the inner area Q a stop 105. In the exemplary embodiment shown, the stop 105 is a step that results from the different thicknesses of the mass approach area P and the inner area Q.
    Figure 5 shows a preferred embodiment of the flywheel 10 as a spoked wheel 50. Suitably, both flywheel masses 10, 10 'and flywheels 11, 11' as a spoke wheel 50 is formed. The spoked wheel 50 includes a mass approach area P, which is as described above. The inner region Q of the spoked wheel 50 extends from the shaft passage opening 103 in the hub 53 to the stop 105 for the mass additive 101 and comprises a series of recesses 52 which are arranged between spokes 51. The spokes 51 connect the hub 53 to the ground lug portion P of the spoke wheel 50, which has a stop 105 in the form of an annular step. By means of the recesses 52, mass is saved in the region of the spokes 51, that is to say in the inner region Q of the spoked wheel 50. In this area, the centrifugal forces acting on the mass of the spoked wheel during training are lower in comparison with the centrifugal forces acting on a similar mass radially further away from the axis of rotation AR, so that mass can be saved here without reducing the total weight of the sports device 1 Training effect too much to worsen. It succeeds in this way an advantageous displacement of the center of gravity of the spoke wheel radially away from the axis of rotation Ar.
    In order to achieve a uniform distribution of the traction cable 12 on the take-up area 104 of the shaft 8, transfer jaws 60, 60 'are provided, as shown in FIG. The envelope jaws 60, 60 'define the take-up area 104 of the shaft 8 in both directions. Toward the take-up area 104, they each have a concave surface 61. If the traction cable 12 is wound on the shaft 8 by the rotation of the shaft 8, this results in a winding along the longitudinal extension of the shaft 8. If the traction cable 12 hits one of the transferring jaws 60, 60 'or one of the concave surfaces 61, then the direction the winding is reversed and the pull rope continues to wind on the shaft 8 in the direction away from the turnup jaw 60, 60 '. The transfer jaws 60, 60 'in this case prevent the formation of 8 balls of the tension line 12 at the ends of the take-up area 104 of the shaft, which then lead to uneven winding or unwinding of the pull cable 12. Rather, the pull rope 12 winds in a uniform, as few superimposed layers arranged winding on the shaft 8.
    When transporting the sports equipment 1 should be avoided that the pull rope 12 unwinds by itself. To accomplish this, a parking brake 70 is provided, as shown in FIG. The parking brake 70 comprises a pin 72 which is guided through the frame member 5 of the sports equipment 1 and connected to a grip head 73. By a spring 74 grip head 73 and pin 72 are biased in the direction of the flywheel 10, 10 '. By this bias, the pin 72 engages in the latching direction 75 in one of the recesses 71, which are formed as notches on the front-side outer edge flywheels 11, 11 '. The latching recesses 71 are milled into the flywheel 10, 10 'or the flywheel 11, 1T, for example. Preferably, a plurality of, for example, four, recesses 71 on the circumference of the flywheel 10, 10 'and the flywheel 11, 11' arranged distributed. By locking the parking brake 70, the rotation of the flywheel 10,10 'and the flywheel 11, 11' difficult. While rotation is still possible when a user pulls hard on pull cable 12, it is accompanied by a loud noise that points to the activated parking brake 70. The noise is achieved by sliding the pin 72 on the outer edge of the flywheels 11, 11 'and repeated engagement in the respective recesses 71. The parking brake 70 can be released by the handle head 73 is pulled against the locking direction 75 and against the bias of the spring 74. The parking brake may be tilted against the frame member 5, causing the parking brake 70 to remain in the released position until the user again rotates the handle head 73 relative to the frame member 5 such that the spring 74 can move the pin 72 through the frame member 5, so that the pin 72 either rests on the circumference of the flywheel 10, 10 'or engages in a latching recess 71.
    Figure 8 shows the sports equipment with a mounted housing 13, in particular the shaft 8 and the flywheel 10, 10 'at least partially surrounds. The housing 13 is thereby struck on the frame member 5 via fastening devices 33, 33 '. The handles 6, 9 are covered with handles 114, 114 '. The recesses 102 are hidden under the housing 13 and the handles 114, 114 '. In the area of the flywheel 10, 10 'has the housing 13 on its upper side 41 and / or its underside 43 an opening 15 which allow free access to the flywheel 10, 10' and in particular to the flywheels 11, 11 '. About this opening area, the flywheel 10, 10 'and thus also arranged in the interior of the housing 13 shaft 8 can be set in rotation, in particular in the unrolled state, the tension cable 12 rewind. The housing may be on the invisible, hidden from the frame member 5 rear upper
    Area another opening, corresponding to the opening 15, have, or it can be present only one opening 15. The same applies to the invisible underside area of the sports equipment.
    As can be seen in particular from FIG. 8, the openings 15 enable the attachment or dismantling of additional mass elements to the flywheels 11, 11 '. For this purpose, the openings 15 are so large that a user can bring the mass additive elements through the openings 15 to the flywheels 11, 11 'or remove them again, without having to open the housing 13. Through the openings 15 and the glands 111 can be reached, so that they can be solved or tightened. An adaptation of the training effort by means of the mass additive elements is thus easily and quickly possible, whereby the motivation of the trainee or can be increased.
