Definitions

• the invention relates to a training device with two handle elements, between which a rotary body is arranged, which has two passages through which a cable connected to the handle elements is guided.
• a training device with two handle elements, between which a rotary body is arranged, which has two passages through which a cable connected to the handle elements is guided.
• Such a training device is described for example in WO 2005/046805.
• the rotating body is usually designed as a flywheel, which has a weight of, for example, a few 100 grams. By repeatedly pulling on the handle parts, the flywheel is accelerated with each pull in the opposite direction. Due to the inertia of this case occur sufficiently high forces that can be used for training purposes for selected muscle areas.
• Such a training device is characterized by its simple design and its compactness with very flexible application options. Such a training device can be used in particular for therapeutic purposes to build up selected muscle parts.
• the training device can be here not only in the horizontal direction, ie when the rope is substantially horizontal, press, but also in any other spatial directions, so for example obliquely or vertically. In vertical alignment, however, the problem arises that the rotational body by its own weight along the rope to slide down on the lower handle member. Anti-slip devices attached to the rope or knots inserted into the rope are less suitable for remedying the problem, since they interfere with routine replacement of the rope, for example.
• the invention is based on the object in such a training device in a vertical training use to prevent slippage of the rotating body down and at the same time to ensure the highest possible user comfort.
• the object is achieved according to the invention by a training device having the features of claim 1.
• this training device is provided that the bushings through the body of revolution through which the rope is guided, not as usual parallel to the axis of rotation, but obliquely inclined to this run ,
• the bushings therefore run at an angle of inclination to the axis of rotation of a side surface through the usually disc-shaped, in particular solid body of revolution to the opposite side surface. They therefore run at the same time obliquely inclined to a plane to which the axis of rotation forms the vertical.
• This embodiment is based on the idea of increasing the friction between the cable and the wall region of the bushing through the oblique guide through the body of rotation, so that slipping of the body of rotation downward at a vertical training position is thereby at least largely avoided.
• a particular advantage of this obliquely oriented implementation is to be seen in the fact that further a simple implementation of the ropes, for example, when replacing a rope is easily possible.
• the increased friction occurs preferably even at low tensile loads in the training situation when the rope is pulled to unthread or twist the rope. Due to the tensile force exerted, because of the non-parallel orientation of the lead-through openings, the rope is pressed against a wall area in training mode.
• the rotary body is preferably formed as a solid flywheel made of solid material and in particular typically has a weight of several 100 grams, for example in the range of 100 to 300 grams, preferably in the range of about 175 grams.
• the rotation body can be made of metal, Plastic or preferably hard rubber exist.
• the diameter of the disc is in the range of typically a few centimeters, for example in the range between 5 and 10 cm, preferably approximately in the range of 7.5 cm.
• the thickness of the flywheel is for example a few centimeters, in particular about 2.5 cm.
• the bushings extend obliquely to the axis of rotation over their entire length. This allows a simple introduction of the bushings, for example, by an obliquely with respect to the rotation axis scheduled hole. Preferably, therefore, the bushings also extend straight through the body of revolution.
• the bushings intersect in the rotation body.
• the bushings traverse the center of the rotating body, but without crossing.
• the subregions of the rope which are passed through the rotary body also intersect.
• the angle of inclination is in the range between 15 ° and 60 °.
• the angle of inclination is in the range between 30 ° and 50 °.
• it is about 45 °, so that the angle between the two sections of the rope is 90 °. tries have shown that with such an angle slipping is particularly effectively prevented.
• the bushings have at least two sections which are oriented at different angles to the axis of rotation.
• the two sections each extend obliquely from the outside of the body of rotation obliquely in the direction of the axis of rotation and meet approximately in the middle of the body so that they are formed in an approximately V-shaped optionally with a rounded area in the middle.
• the cuts do not necessarily have to be straightforward.
• the subregions are curved or or that the bushings are designed to be curved overall.
• the two passages are preferably curved in each case convex to the axis of rotation.
• the subregions can also point away from the axis of rotation, for example concavely or at an angle.
• the bushings expediently have a diameter which is between 1, 3 and 3 times the rope diameter.
• the bushings each end have insertion bevels at their inlet and outlet side. These are expediently asymmetrical and formed towards the axis of rotation.
• 1 is a training device with a flywheel as a rotational body and tape loops as gripping elements
• FIG. 2 is a sectional view through the flywheel according to a first alternative taken along the line M-II in Figure 3 with performed cable sections,
• FIG. 3 is a plan view of the flywheel of FIG. 2,
• Fig. 4 is a schematic representation of a second alternative with angularly oriented passages
• Fig. 5 shows a third alternative embodiment with convexly curved passages.
• the training device has two gripping elements designed as belt loops 2, to which a cable 4 is fastened, which is carried out in two bushings 8 by means of a rotating body 6 designed as a flywheel 6.
• the flywheel 6 is formed by a solid body of solid material, such as metal hard rubber, which is penetrated only by the preferably designed as holes bushings 8.
• the belt loops 2 are made, for example, of a textile material, of plastic or of another elastic material, such as rubber.
• other grip elements such as rings, rods, etc. may be provided.
• the belt loops 2 offer the advantage that they offer a high level of comfort and, in particular, also expand the field of application, for example by gripping the belt loops 2 not only by hand, but e.g. can also be placed around a body part, such as foot or head.
• the functioning of the training device is as follows:
• the rope 4 is twisted slightly by manually rotating the flywheel 6. Subsequently, the twisted rope is untwisted by pulling on the belt loops 2 and the flywheel 6 in rotation about its axis of rotation 10th added. The rotation of the flywheel 6 then leads to a twisting in the opposite direction, which is again untwined by pulling on the belt loops 2, etc. In this case, very high forces and moments of inertia can occur depending on the rotational speed generated.
• the training device is functional in any orientation. Sometimes it is also operated in vertical or oblique direction. In this mode of operation, there is the problem that the flywheel 6 slips in the direction of the lower belt loop 2 and is no longer centrally located.
• the passages 8, which are arranged on both sides of the axis of rotation 10, extend obliquely to the axis of rotation 10 through the flywheel 6.
• the bushings 8 are formed as a straight through the entire flywheel 6 passing through bore holes, which intersect in the middle of the flywheel 6, so halfway up. The crossing point lies on the axis of rotation 10.
• the two partial regions 4A, 4B form a type of pocket or gusset region, which is filled by a central center piece 12 of the flywheel 6.
• the two subregions 4A, 4B virtually surround this centerpiece 12.
• the bushings 8 each have insertion bevels 14 at their inlet and outlet openings. These are asymmetrical in the embodiment and in particular provided only to the center piece 12. Notwithstanding the merely schematic representation, the middle piece 12 is rounded overall in the region of the insertion bevel in order to keep the load on the rope 4 as small as possible.
• the diameter of the bushing 8 In order to allow easy insertion of the cable 4 and at the same time to ensure a sufficiently high friction is the diameter of the bushing 8, so its clear width, approximately in the range of 1, 3 to 2 times the rope diameter. This is for example 3 mm and the diameter of the bushings 8 is about 5 mm.
• the passages 8 are arranged inclined with respect to the axis of rotation 10 at an inclination angle ⁇ . This is about 45 ° in the embodiment.
• the distance between the two passages 8 is typically in the range of 1 to 3 cm.
• the respective passage 8 is formed from two sections 8A.8B which are oriented at an angle to one another.
• the mutually facing tips of the angled bushings 8 are spaced apart, so that the bushings 8 do not intersect. Notwithstanding the illustrated angle peak this is preferably performed rounded to form no scharkantigen deflection for the rope.
• a continuous curved configuration of the passages 8 is provided.
• the radius of curvature is constant. Notwithstanding the illustrated embodiments are also combinations of curved portions with rectilinearly extending portions as well as with those portions which extend parallel to the axis of rotation 10 are possible.
