Abstract

  The training device comprises two gripping elements (2), between which the flywheel (6) is suspended on a rope (4). By twisting the rope and repeatedly pulling the gripping element (2), the flywheels (6) are rotated about their axis of rotation (10). The rope (4) is guided through two penetrations (8) that penetrate the flywheel (6). In this case, the penetration portion (8) extends obliquely with respect to the rotation axis (10). This increases the friction between the rope and the wall of the penetrating part in the training operation, and the slip of the flywheel (6) along the rope (4) is avoided during the vertical training operation.

Description

  The present invention includes a rotating body having two gripping elements between which a rotating body is disposed and two penetrating parts, and a rope coupled to the gripping element is guided through the two penetrating parts. It relates to a training device. By twisting the rope and repeatedly pulling the rope, the rotating body is rotated about its axis of rotation.

  Such a training apparatus is described in, for example, pamphlet of International Publication No. 2005/046805.

  The flywheel is usually formed as a rotating body having a weight of, for example, several hundred grams. By repeatedly pulling the gripping part, the flywheel is accelerated in the opposite direction each time it is pulled. In this case, due to the mass inertia, a sufficiently large force is generated that can be used for training purposes of the selected muscle region.

  Such a training device stands out because of its simple construction and at the same time compactness allowing a wide range of use. Such a training device can also be used for therapeutic purposes, in particular to create selected muscle parts.

  In this case, the training device can be operated not only in the horizontal direction, i.e. when the rope extends substantially horizontally, but also in any other spatial direction, i.e. for example diagonally or vertically. In the case of a vertical orientation, of course, the problem arises that the rotating body slides along the rope towards the lower gripping element due to its own weight. Anti-skids attached to the ropes or knots made in the ropes are also not very suitable for countermeasures, because they get in the way, for example during regular exchanges of ropes.

  An object of the present invention is to prevent the downward displacement of the rotating body and to ensure the highest possible user comfort when using such a training apparatus for vertical training. .

  This object is achieved according to the invention by an apparatus having the features of claim 1. In this training device, it is intended that the penetrating portion extending through the rotating body guided by the rope is not parallel to the rotation axis as usual, but is inclined obliquely with respect to the rotation axis. Thus, the penetrating portion extends from the side surface to the opposite side surface through a disk-shaped, particularly solid rotating body, at an angle of inclination with respect to the axis of rotation. Therefore, the penetrating portion extends at an angle with respect to the plane in which the rotation axis forms a perpendicular line.

  In this case, this configuration increases the friction between the rope and the wall area of the penetration by means of an oblique penetration through the rotator, so that this results in the lower part of the rotator in the vertical training position. This is based on the idea that at least a large amount of misalignment is avoided. In this case, the particular advantage of this obliquely oriented penetration is furthermore seen that simple guidance of the rope is possible without problems, for example when changing the rope. The increase in friction preferably occurs easily in training conditions, even at small tensile loads, when the rope is pulled to unwind or twist the rope. Due to the non-parallel orientation of the through-openings, the tension is exerted, i.e. the rope is pressed against the wall area in a training movement.

  The rotator is preferably formed from solid material as a solid flywheel and has a weight typically in the range of several hundred grams, for example in the range of 100 to 300 grams, preferably in the range of about 175 grams. The rotating body can be made of metal, plastic or preferably hard rubber. The diameter of the disc is typically in the range of a few centimeters, for example in the range of 5-10 cm, preferably in the range of about 7.5 cm. The thickness of the flywheel is, for example, a few centimeters, in particular about 2.5 cm.

  According to the form suitable for the purpose, the through portions extend obliquely with respect to the rotation axis over their entire length. This makes it possible to easily form the through portion by using a drill obliquely with respect to the rotation axis, for example. Therefore, it is preferable that the penetrating portion similarly linearly extends through the rotating body.

  According to a preferred form, the penetrations intersect within the rotating body. As an alternative, the penetrations can also cross the center of the rotating body, but it is also possible not to cross each other. Preferably, additionally, it is intended that the partial areas of the rope that are guided through the rotary body also intersect. This measure ensures that the displacement of the rotating body along the rope is easily prevented with very little tensile stress. The rotating body is supported by the partial regions of the intersecting ropes, that is, in the wedge-shaped region formed by the intersecting partial regions. This configuration is simply achieved as a through-opening by two intersecting and continuous holes, which intersect at the center, ie half the height inside the rotating body. The partial areas of the rope are guided to each other at the intersection and contact there.

  According to a development suitable for the purpose, in particular in the case of intersecting penetrations, the penetrations are intended to be oriented with an inclination angle preferably in the range of 15 ° to 60 ° with respect to the axis of rotation. In particular, the inclination angle is in the range of 30 ° to 50 °. According to a preferred form, the angle of inclination is approximately 45 °, so that the angle between both partial areas of the rope is 90 °. Tests have shown that such an angle prevents slipping particularly effectively.

  Instead of a continuous linearly extending penetration, according to a suitable form, it is intended that the penetration comprises at least two parts (pieces) oriented at different angles with respect to the axis of rotation. In this case, preferably, both parts (pieces) extend obliquely in the direction of the axis of rotation from the outside of the rotating body and meet substantially at the center of the rotating body, so that the parts (pieces) are approximately V It is intended that the character shape is formed by chamfering the central region as necessary.

  The piece does not necessarily have to be straight. Alternatively, it is also possible for the partial region to be bent or the penetration part to be bent entirely. In this case, it is preferable that both penetration parts are each bent in a convex shape with respect to the rotation axis. In principle, the partial region can also be shown away from the axis of rotation, for example bent concavely or at a right angle.

  In order to allow easy introduction and penetration of the rope through the penetration and at the same time easily ensure increased friction at small tensile loads, the penetration is 1.3-3 times the rope diameter, depending on the purpose. Having a diameter of

  During twisting and unwinding of the rope during the training operation, a large load is generated on the rope in the area of the entrance of the penetration, so that the penetration is on the end side, i.e. on their entry side or exit side, depending on the purpose. Each is intended to have a leading slope. In this case, the introduction slope is formed asymmetrically toward the rotation axis in accordance with the purpose.

  Next, embodiments of the present invention will be described in detail with reference to the drawings. Each is shown in a simplified schematic.

1 is a drawing of a training device having a flywheel as a rotating body and a belt loop as a gripping element. FIG. 4 is a cross-sectional view of a flywheel according to a first alternative, taken along line II-II in FIG. FIG. 3 is a top view of the flywheel according to FIG. 2. FIG. 6 is a schematic view of a second alternative having penetrations oriented perpendicular to each other. FIG. 6 is a third alternative drawing having a convexly curved through section.

  In the figure, the same reference numerals are assigned to parts that act the same.

  The training device according to FIG. 1 comprises two gripping elements formed as a belt loop 2, to which a rope 4 guided through two penetrations 8 of a rotating body formed as a flywheel 6 is fixed. The The flywheel 6 is formed of a solid body made of a solid material, for example metal or hard rubber, which solid body is penetrated only by a penetration 8 preferably formed as a hole. The belt loop 2 is made of, for example, a fiber material, a plastic, or another elastic material such as rubber. Instead of the belt loop 2, other gripping elements such as rings, rods etc. can also be provided. However, the belt loop 2 provides a high grip comfort and the belt loop 2 is not only gripped by the hand, but can also be placed around a body part, for example a foot or head. Being able to do so offers the advantage of extending the range of use in particular.

  The function of the training device is as follows. First, the rope 4 is twisted somewhat by manually rotating the flywheel 6. Next, by pulling the belt loop 2, the twisted rope is unwound and the flywheel 6 is rotated about their axis of rotation 10. The rotation of the flywheel 6 then causes a twist in the opposite direction, which twist is again unwound by pulling on the belt loop 2. In this case, very high forces and moments of inertia are generated based on the generated rotational speed.

  With this simple training device, different muscle regions can be trained effectively and easily. The training device can function in any orientation. In some cases, the training device is operated in a vertical or diagonal direction. This method of operation has the problem that the flywheel 6 is displaced in the direction of the lower belt loop 2 and is no longer centered.

  In order to avoid this, it is intended that the through portions 8 arranged on both sides of the rotation axis 10 extend through the flywheel 6 obliquely with respect to the rotation axis 10.

  According to the first embodiment shown in FIG. 2, the penetration 8 is formed as a perforated hole that passes straight through the entire flywheel 6, and these holes are at the center of the flywheel 6, ie half the Intersect at height. In this case, the intersection point is located on the rotation axis 10.

  Through both of these penetrations 8, a respective partial area 4A, 4B of the rope 4 is guided. Both partial areas 4A, 4B intersect in this case in the same way, i.e. are guided through the flywheel 6 in a straight line as well. At the intersection, both partial areas 4A and 4B are in contact with each other.

  As can be seen from the cross-sectional view of FIG. 2, both partial areas 4 </ b> A, 4 </ b> B form a kind of pocket or wedge-shaped area that is filled by the middle piece 12 in the center of the flywheel 6. Both partial regions 4A and 4B abut so as to substantially wrap around the intermediate piece 12.

  The penetration part 8 is provided with the introductory slope 14 in those inlet openings or outlet openings, respectively. These openings are formed asymmetrically in the embodiment, and are provided only particularly for the intermediate piece 12. Unlike merely a schematic drawing, the intermediate piece 12 is generally rounded in the region of the introduction ramp in order to keep the load on the rope 4 as small as possible.

  In order to allow easy introduction of the rope 4 and at the same time ensure a sufficiently high friction, the diameter of the penetration 8, i.e. the inner width of the penetration, is approximately 1.3 to 2 times the rope diameter. The diameter of the rope is, for example, 3 mm, and the diameter of the penetrating portion 8 is about 5 mm.

  The penetrating portion 8 is disposed to be inclined with respect to the rotation axis 10 by an inclination angle α. This inclination angle is about 45 ° in the embodiment.

  From the top view of the flywheel 6 having a circular cross section, the asymmetric formation of the inlet slope 14 formed only on the inlet opening of the penetration 8 and on the side oriented with respect to the rotation axis 10 is recognized. The spacing between both penetrations 8 is typically in the range of 1 to 3 cm.

  In the case of the alternative embodiment according to FIG. 4, each penetration 8 is formed from two parts (pieces) 8A, 8B which are oriented perpendicular to each other. The leading ends of the penetrating portions 8 formed at right angles are directed away from each other, and as a result, the penetrating portions 8 do not intersect. Unlike the angle tip shown, it is preferred that the angle tip be rounded so as not to form an angular turning point of the rope.

  Finally, in the case of a variant of the embodiment according to FIG. 5, a continuously curved shape of the penetration 8 is provided. In the embodiment, the radius of curvature is constant.

  In contrast to the variant of the embodiment shown, it is likewise possible to combine curved partial areas with linearly extending partial areas and with partial areas extending parallel to the rotation axis 10.
