Description

Exercise machine for physical exercises

The present invention relates to a training device for physical exercises with a footprint for support for a user during the exercise and egg ner curved standing surface for pivotal support of the training device on a substrate, wherein the footprint relative to the base by we least one support member is supported rigidly supported.

Such as "balance board" or "Wackelbrett" designated training ningsgeräte be used to train the sense of balance or sporttherapeuti's purposes. In a simple embodiment, such a training device comprises a disk set on a hemisphere, on which a user can balance using his body.

To increase the demands on the neuromuscular system training devices are also offered in which a footprint forming board on a free-moving ball, such as a rubber ball, can be balanced. An increased use of the body is necessary to launch the training device so that better training results can be achieved. However, the use of such a training device by the decoupling of footprint and footprint is very demanding and involves a high risk of injury. The invention is therefore based on the object to provide a training device of the type mentioned, with the better training results can be achieved with minimal risk of injury.

The object is achieved by a training device with the features of the preamble of claim 1, wherein the training device has a liquid-tight, contiguous cavity and a filler neck with a United circuit, wherein on the filler neck a liquid in the cavity can be filled and the route between two extreme dimensions of the hollow space on at least one perpendicular to a running through the training device and the standing surface vertical central axis of the training device straight line is at least 30 cm.

When performing the physical exercises, the cavity is covered with a liquid that can flow in such a way that the center of gravity of the training device essentially depends on the position of the liquid in the cavity.

For the liquid to flow, the cavity is not completely affected by the liquid speed. Preferably, the cavity is at least 30% of its volume, preferably at least 50% of its volume, infested with the liquid.

The center of gravity of the training device is made up of the mass balance of the empty training device and the center of gravity of the liquid speed together. The center of mass of the training device depends in this case on sentlichen of the position of the liquid in the cavity, as soon as the mass of liq fluid has at least one-fifth of the mass of the empty training device. Before given to the mass of the liquid is greater than or equal to the mass of the empty Trai ningsgeräts.

The flow and the inertial behavior of the liquid causes a difficult to see before displacement of the center of mass of the training device, whereby a greater physical effort of the user to balance the training device is necessary. In this case, the risk of injury is minimal, as a controlled guidance of the training ningsgeräts by the user is possible by the rigid support of the footprint over the floor space.

The dimensions of the cavity are designed so that the distance between two outermost dimensions of the cavity on at least one perpendicular to the vertical center axis of the training device extending straight line is at least 30 cm. This allows a shift of the liquid and therefore the center of gravity of the training device in a sufficiently spaced from the vertical central axis position on which the user must reagieren by increased use of his body. Preferably, this distance is at least 40 cm. Especially before given to the distance between two extreme dimensions of the hollow space on at least one perpendicular to the vertical center axis of the training device extending straight line is at least 90% of the distance between two extreme measurements from the training device on the same line. The vertical central axis runs centrally through the training device and the stand area. In a balanced position of the training device, the Vertikalmittelach se perpendicular to a flat, horizontal surface on which the Trainingsge advises and which does not belong to the invention. Preferably, the vertical axis also passes through the geometric center of gravity of the footprint. For example, the vertical central axis runs through its center in a round footprint. In a simple embodiment, the footprint is planar so that in the balanced position of the exerciser it extends parallel to a flat, horizontal surface on which the exerciser stands.

In a preferred embodiment of the invention, the cavity occupies at least 25%, preferably at least 50%, particularly preferably at least 75%, of the volume of the training device. This extends the range of motion for the fluid. The shift of the center of mass of the training device is thus even worse predictable, so that a better training result can be achieved.

In a further preferred embodiment of the invention, the cavity is bounded by a rigid wall which forms the support element. The wall is thus resistant to high loads, whereby the training device BE is more permanent. By the rigid wall forms the support element, a be particularly compact and inexpensive design of the training device is possible. In particular, while at least part of the base is formed integrally with the Wan extension of the cavity, whereby a particularly compact and cost-effective design of the training device is achieved.

According to a further advantageous embodiment of the invention is vorgese hen that at least a portion of the footprint of the training device along a con tricity of a spherical segment having a radius of 150 mm to 200 mm, preferably from 170 mm to 180 mm, particularly preferably of 175 mm, supporting is arranged. Through this geometry, the training device can be continuously tilted and thus guided controlled. At the same time, the choice of the radius ensures a sufficient degree of difficulty for the physical exercises.

In the simplest case, the base surface for this purpose has the shape of a spherical segment with the corresponding radius. Alternatively or additionally, knobs, corks, fingers, spikes and / or other elevations may be provided, the tips of which are arranged along the contour of a spherical segment with a corresponding radius and support the exerciser along this contour.

In a further preferred embodiment of the invention, the training device has a tilt limiting element, which the inclination of the vertical central axis relative to a flat, horizontal surface to a maximum inclination angle of 10 ° to 30 °, preferably from 15 ° to 25 °, particularly preferably from 20 ° , limited. The angle of inclination is an angle between the vertical central axis se of the training device and a perpendicular to a flat, horizontal sub-ground extending vertical axis defined.

Will that stand with his footprint on a flat, horizontal surface de training device tilted to the maximum inclination angle, the inclination limiting element supports the training device in addition to the floor space and thus verhin changed beyond the slope of the training device. This prevents a user from falling during exercise due to excessive inclination of the footprint of the exerciser, thereby minimizing the risk of injury. Preferably, the inclination limiting element with respect to the vertical center axis of the training device is circumferentially erstre ckend circumferentially. Alternatively, a plurality of circumferentially arranged tilting restriction members may be provided.

In particular, the inclination limiting element is formed integrally with the wall of the cavity, whereby a particularly compact and inexpensive construction of the training device is achieved.

In a further advantageous embodiment of the invention, the cavity has at least one constriction for influencing the flow behavior of the liquid in at least one cutting plane extending parallel to the vertical axis. Constriction is an obstacle to the fluid that must overcome or flow past it. This leads to an even more unpredictable shift of the center of gravity of the training device, so that this under higher use of the Body needs to be balanced. In particular, the constriction is formed by the wall of the cavity.

Advantageously, the training device has at least one cavity surrounded by the Barri ereelement, which extends from one of the footprint facing ceiling area of the wall of the cavity toward a bottom surface of the abgewand th floor area of the wall of the cavity. The barrier element thus represents an obstacle to the liquid that must bypass the liquid. Such influencing the flow behavior of the liquid leads to an even more unpredictable shift of the center of gravity of the training device, so that it must be balanced with increased use of the body.

In particular, the barrier element is formed integrally with the wall of the cavity, whereby a particularly compact and inexpensive construction of the training device is achieved.

In a further particularly preferred embodiment of the invention is vorgese hen that at least one spacer element between the ceiling region of the Wan extension of the cavity and the bottom portion of the wall of the cavity is arranged, which spaced the ceiling area from the bottom area. As a result, the cavity is more resistant to forces that act in particular parallel to the vertical central axis of the cavity (for example, the weight of the user), so that the training device is more stable. Particularly preferably, the spacer element is formed by the support element. In particular, the spacer element is formed integrally with the wall of the cavity, whereby a particularly compact and inexpensive construction of the training device is achieved. Particularly preferably, at least one Barriereele element is simultaneously formed as a spacer element.

According to a further advantageous embodiment of the invention, the training ningsgerät on at least one Verwirbelungskammer in the cavity, which is on the one side to the cavity to open out of the flow behavior of the liquid to the influence. The opposite of the rest, adjacent region of the cavity ver deep or protruding vortex chamber causes a part of the same when entering the liquid enters the cavity area bounded by the Verwirbelungskammer and is prevented from continuing to flow. Furthermore, when the liquid enters the swirling chamber, turbulences occur which influence the flow direction of the liquid in an uncontrollable manner. As a result, the displacement of the center of gravity of the training device is still unpredictable, so that it must be balanced with greater use of the body.

In particular, the swirling chamber is formed integrally with the wall of the hollow space, whereby a particularly compact and inexpensive Bauwei se of the training device is achieved.

In a further advantageous embodiment of the invention is a part of the quantitative menhängenden cavity as with respect to the vertical central axis in the circumferential direction revolving pool forms out to influence the flow behavior of the liquid. As a result, at least a portion of the liquid does not flow in the direction of the lower-positioned portion of the cavity at an inclination of the training device, but in the circumferential direction following the pelvis. As a result, the Ver storage of the center of gravity of the training device is even more unpredictable, so that the training device must be balanced with increased use of the body.
