Definitions

  • the invention relates to an exercise device with two grip elements between which a rotation body is arranged, the rotation body having two passages through which a cord connected to the grip elements is guided. By twisting the cord and repeatedly pulling on the cord, the rotation body is caused to rotate about its rotation axis.
  • the rotation body is usually designed as a flywheel having a weight of, for example, several hundred grams. By the repeated pulling on the grip parts, the flywheel is accelerated in the opposite direction at each pull. By virtue of the mass inertia, sufficiently high forces arise here that can be used for training purposes for selected muscle regions.
  • An exercise device of this kind is distinguished by being of a simple design and compact, while at the same time permitting a wide range of uses.
  • an exercise device of this kind can also be used for therapeutic purposes for building up selected muscles and muscle regions.
  • the exercise device can be used not only in the horizontal direction, that is to say with the cord extending substantially horizontally, but also in any other desired spatial direction, for example obliquely inclined or also vertically.
  • the problem arises that the rotation body slips down the cord, under its own weight, toward the lower grip element.
  • Anti-slip devices mounted on the cord, or knots made in the cord are not especially suitable for remedying this problem, for example since they get in the way during routine changing of the cord.
  • an exercise device comprising:
  • rotation body disposed between the two grip elements, the rotation body being a flywheel formed as a massive disk element of substantially solid material and having two through-passages formed therein;
  • the through-passages running at least partially obliquely inclined with respect to a rotation axis of the rotation body and wherein, after the cord has been twisted, the rotation body is caused to rotate about the rotation axis when the cord is repeatedly pulled;
  • the objects of the invention are achieved with an exercise device, wherein the passages which extend through the rotation body and through which the cord is guided are not parallel to the rotation axis, as is normally the case, but instead are inclined obliquely with respect to the rotation axis.
  • the passages therefore extend, at an angle of inclination with respect to the rotation axis, from one side face through the usually disk-shaped and in particular solid rotation body to the opposite side face. They therefore extend at the same time inclined obliquely to a plane to which the rotation axis forms the perpendicular.
  • This embodiment is based on the notion of using the oblique passage through the rotation body to increase the friction between the cord and the wall area of the passage, such that in this way the rotation body is at least substantially prevented from slipping down in a vertical training position.
  • a particular advantage of this obliquely oriented passage is to be seen in the fact that the cords can also be guided through simply and without any problem, for example when exchanging of a cord.
  • the increased friction preferably arises even at low tensile loads in the training situation, when the cord is pulled in order to untwist or twist the cord. Because of the non-parallel orientation of the passage openings, the tensile force exerted in fact causes the cord to be pressed against a wall area in the training mode.
  • the rotation body is preferably designed as a solid flywheel made of solid material and, in particular, typically has a weight of several hundred grams, for example in the range of 100 to 300 grams, preferably in the region of about 175 grams.
  • the rotation body can be made of metal, plastic or, preferably, hard rubber.
  • the diameter of the flywheel is in the range of typically several centimeters, for example in the range between 5 and 10 cm, preferably about 7.5 cm.
  • the thickness of the flywheel is a few centimeters for example, in particular about 2.5 cm.
  • the passages extend obliquely with respect to the rotation axis along their entire length. This permits simple formation of the passages, for example using a drill applied obliquely with respect to the rotation axis. Therefore, the passages preferably also extend rectilinearly through the rotation body.
  • the passages intersect each other in the rotation body.
  • the passages cross the center of the rotation body, but without intersecting each other.
  • the subregions of the cord that are guided through the rotation body likewise intersect each other. This measure ensures that, even at very low tensile stresses, the rotation body is prevented from slipping along the cord.
  • the rotation body is in fact supported as it were in a gusset area formed by the intersecting subregions.
  • This embodiment is easily obtained by two intersecting and continuous bores as passage openings, which intersect each other at the center, that is to say at mid height, inside the rotation body. The subregions of the cord are guided past each other at the intersection point and touch each other there.
  • these passages are oriented at an angle of inclination with respect to the rotation axis, which angle preferably lies in the range between 15° and 60°.
  • the angle of inclination particularly lies in the range between 30° and 50°. According to a preferred embodiment, it is approximately 45°, such that the angle between the two subregions of the cord is 90°. Trials have shown that slipping is avoided particularly effectively with such an angle.
  • another expedient embodiment is one in which the passages have at least two subsidiary sections that are oriented at different angles with respect to the rotation axis.
  • the two subsidiary sections each extend rectilinearly from the outer face of the rotation body and obliquely with respect to the rotation axis and meet approximately at the center of the body, such that they are approximately V-shaped, if appropriate with a rounded area at the center.
  • the subsidiary sections do not necessarily have to be rectilinear. It is alternatively also possible that the subsidiary sections are curved or that the passages as a whole are curved. In this case, the two passages are each preferably convexly curved toward the rotation axis. In principle, the subsidiary sections can also point away from the rotation axis, for example with a concave curvature or at an angle.
  • the passages expediently have a diameter that is between 1.3 and 3 times the diameter of the cord.
  • the passages have insertion bevels at each end, i.e. at their inlet and outlet end. These insertion bevels are expediently designed asymmetrically and toward the rotation axis.
  • FIG. 1 shows an exercise device with a flywheel as rotation body and with band loops as grip elements
  • FIG. 2 shows a cross-sectional view through the flywheel according to a first alternative, along the line II-II in FIG. 3 and with cord subregions guided through;
  • FIG. 3 shows a plan view of the flywheel according to FIG. 2 ;
  • FIG. 4 shows a schematic view of a second alternative, with passages oriented at an angle to each other;
  • FIG. 5 shows a third alternative embodiment with convexly curved passages.
  • FIG. 1 there is shown an exercise device or apparatus according to the invention.
  • the exercise device has two grip elements designed as band loops 2 on which a cord 4 is secured.
  • the cord 4 which may also be referred to as a cable, a line or a rope, is guided through two through-passages 8 , passages 8 for short, in a rotation body, which is designed as a flywheel 6 .
  • the flywheel 6 is formed by a solid body made of solid material, for example metal or hard rubber, which is breached only by the passages 8 .
  • the latter are preferably configured as bores.
  • the band loops 2 are made, for example, of a textile material, of plastic or also of another elastic material, such as rubber.
  • other grip elements such as rings, rods, etc. can also be provided.
  • the band loops 2 have the advantage that they offer a high degree of gripping comfort and, in particular, they also extend the range of possible uses, for example by the band loops 2 not only being gripped by hand but instead, for example, also being able to be placed around a part of the body, for example a foot or the head.
  • the function and operation of the exercise device is as follows:
  • the cord 4 is first of all twisted slightly by the manual rotation of the flywheel 6 .
  • the twisted cord is then untwisted by pulling on the band loops 2 , and the flywheel 6 is caused to rotate about its rotation axis 10 .
  • the rotation of the flywheel 6 then leads to a twisting in the opposite direction, and this twisting is reversed again by pulling on the band loops 2 , and so on.
  • Very considerable torques, forces and moments of inertia can develop depending on the speed of rotation that is generated.
  • This simple exercise device allows different muscle regions to be exercised effectively and easily.
  • the exercise device is able to function in any desired orientation. It is also in some cases operated in a vertical or oblique direction. In this mode of operation, the problem arises that the flywheel 6 slips in the direction of the lower band loop 2 and is no longer arranged centrally.
  • the passages 8 which are arranged on both sides of the rotation axis 10 , run through the flywheel 6 obliquely with respect to the rotation axis 10 .
  • the passages 8 are designed as bores that extend rectilinearly all the way through the flywheel 6 and that intersect each other at the center of the flywheel 6 , in other words at mid height. The intersection point lies here on the rotation axis 10 .
  • a respective subregion 4 A, 4 B of the cord 4 is guided through these two passages 8 .
  • the two subregions 4 A, 4 B likewise intersect each other, in other words are likewise guided rectilinearly through the flywheel 6 .
  • the two subregions 4 A, 4 B adjoin each other.
  • the two subregions 4 A, 4 B form a kind of pocket or gusset area, which is filled by a central midpiece 12 of the flywheel 6 .
  • the two subregions 4 A, 4 B engage as it were around this midpiece 12 .
  • the passages 8 each have insertion bevels 14 .
  • These insertion bevels 14 are designed asymmetrically in the illustrative embodiment and in particular are provided only toward the midpiece 12 .
  • the midpiece 12 as a whole is rounded in the area of the insertion bevel, in order to keep the stress on the cord 4 as low as possible.
  • the diameter of the passage 8 i.e. the inner width thereof, lies approximately between 1.3 and 2 times the diameter of the cord.
  • the latter is 3 mm for example, and the diameter of the passages 8 is about 5 mm.
  • the passages 8 are inclined at an angle of inclination a with respect to the rotation axis 10 .
  • this angle is about 45°.
  • the plan view of the flywheel 6 with the circular cross-sectional surface shows the admission openings of the passages 8 and also the asymmetrical design of the insertion bevel 14 , which is formed only on the side oriented toward the rotation axis 10 .
  • the distance between the two passages 8 is typically in the range of 1 to 3 cm.
  • the respective passage 8 is made up of two subsidiary sections 8 A, 8 B, which are oriented at an angle to each other.
  • the tips of the angled passages 8 are directed toward each other but spaced apart, with the result that the passages 8 do not intersect.
  • the tip is shown as being angled, it preferably is formed in a rounded fashion, so as not to form any sharp-edged deflection points for the cord.
