Description

Balance training device

The present invention relates to a balance training device in which a board rests on a rolling element and can roll over this. The present balance training device is similar to that known from the circus "Rola Bola" on the fact that a person exercising is on a running board with which on a rolling body of a ball a ball or a roller is balanced.

Similar balance training devices are already known from other patents.

From DE 4411 736 Cl, for example, a balance training device is known in which a board is arranged with a trough on a rolling body or a rigid ball. The rigid ball can be made of titanium, aluminum or correspondingly reinforced plastic products or rubber, as it is also used in bowling balls.

From US 2004224824 AI a surfboard-like balance exercise device is known in which the balance board has a trough and in which an elastic ball, such as a medicine ball, a basketball, a tennis ball, or any other spherical Abrollkörper is used, which has a certain elasticity.

From US3862768 A a balance board in the form of a hat or sombrero is known, which is placed on a ball of wood and can be balanced on the.

From the US patent application US2007027010 AI a balance board is known with which can be balanced on a hard ball. In this document, Section 8 states that air-filled bodies are not suitable because they deform and become ineffective over time.

US patent US 7775952 Bl discloses a balance training device in which a board is also placed on a ball. In US 7775952 Bl air-filled foot or basketballs are used as a rolling body and it is possible to use different rigid limitations for the rolling body. From the US patent US 8062199 82 a balance board is known which has a boundary at the bottom and which is placed on a ball.

From the international patent application W09811953 and the American patent application US 4,191,371 similar balancing devices are known.

It is desirable to further improve the known balance training devices. It is further desirable to make known the known balance training devices further exercises. It is also desirable to provide a balance training device suitable for BMX, mountain biking, cycling, motorcycling, trial riding and other sports. It is also desirable to improve the usability and ease of use of balance boards to increase the circle of potential users. It is further desirable to simplify and make safer the use of a balance training device.

In accordance with one aspect of the present invention, a balance training device is provided. The balance training device comprises a plate having a tread on an upper surface of the plate and a rolling surface disposed on an underside of the plate. The rolling surface is intended to roll over a rolling element.

The balance training device preferably further comprises a boundary for the rolling element, which can be folded or retracted. Rolling element limit is designed to be movable so that it can fold in or retract if the board were placed with the boundary on a floor. As the boundary extends downwards, it can easily be extended by gravity. The border could also be attached with a foil hinge to maintain its mobility. It can also be provided to use an elastically deformable boundary, which thereby retracts or folds in contact with the ground, so that it deforms. An elastically deformable boundary is also designed so that it forms a substantially insurmountable boundary for the rolling element.

It is possible, for example, to attach a restriction in the form of a substantially strip-shaped flap only in the region of the ends with joints. Such a fixed strip-shaped The flap, which is made of an elastic material, can flex elastically like a beam attached to the ends when the rolling element rolls against the boundary. As a result, the beam, similar to a leaf spring, the spring element can be spring back from the boundary to avoid the partially limited balance positions of the rolling element at the boundary. It is possible with suitable hinges to support a strip-shaped boundary such as a statically determined or statically indeterminate beam to favor such elastic bending of the boundary. It is also contemplated to use a restriction having internal damping. It may be provided to provide any boundary with an elastic element which can be elastically deformed upon contact with the rolling element. It may be advantageous to arrange the elastic element similar to a billiard band on the inwardly facing outer edge of the boundary. Also, the elastic member may be provided with an internal friction to act in a contact with the rolling element damping.

The restriction prevents the plate from rolling down the side of the rolling element and stops movement of the plate before it falls off the rolling element. The boundary ensures that the plate tilts towards the side opposite to a position of the rolling element. The limitations cause the relative movements of balance board are limited relative to the rolling body or the rolling body is compared to the Ba lancebrett out.

The boundaries restrict the movement of the rolling element and to jump down in the direction of the rolling element. However, the limitation also limits the mobility of the plate because the boundaries of a slanted plate will first sit on a floor. Since the downwardly projecting boundaries will first sit on the ground, the angular range in which the plate can be tilted on the rolling element is significantly reduced. The movable, retractable or retractable boundaries allow the entire angular range of the balance plate to be used until the plate itself touches the edge itself on the floor. However, the retractable or retractable limitations must also be able to reliably prevent the plate from rolling down the rolling element.

This can be achieved by flap-shaped boundaries, which can fold in contact with the ground in the direction of a center of the plate, while they stand up when rolling from the inside a rolling element against the boundary. It is also possible to use retractable pins that provide the same functionality as hinged stops. By selecting or setting the maximum tilt angle of the balance board, the beginning of a balance exercise can be simplified. The steeper the balance board is in a starting position, the more power or work must be expended to bring the balance board from the static oblique position to a substantially horizontal balance position. It should be noted that when you use a lot of force, it is harder to dose the force, which reduces the likelihood of being out of balance and allows users to place their feet in a less ergonomic position on the balance board at steep angles. At very steep tilt angles, the exerciser can even slip off the plate. On the other hand, with only very low tilt angles, a balance can be impaired by the fact that the plate more often touches the corners or edges or feet on a floor. The feet may also include steel springs such as coil springs or leaf springs to cushion a placement of the plate on a floor. Coil springs may also be protected by telescopic elements or covers against pinching injuries. A resilient foot can also store a deformation energy that allows it to be easier to climb and to start a balance exercise from a position where two feet rest on the ground. The exercising person can thus feather by utilizing the stored energy in a more horizontal position of the plate.

The boundary is designed to be movable so that the boundary can be completely or partially moved to another position or the boundary can change its position in the room. The boundary could also be made flexible, and include, for example spring steel elements.

According to another aspect of the present invention, there is provided a balance training apparatus having a plate, a tread surface on an upper surface of the plate, and a rolling surface on a lower surface of the plate. The rolling surface is intended to roll over a rolling element. The balance exerciser further includes a handle attached to the plate. A trainer can hold on to the grip while exercising with his hands. The handle is arranged at a distance between 30cm and 100cm, 50cm and 80cm or 60cm and 70cm above the tread. This aspect of the present invention is directed to a balance training device that is particularly intended for training the balance involving the arms. Depending on the position of the handle or handles, greater force is applied when balancing through the arms. In an exemplary embodiment of the balance training device, this further comprises a rolling element, wherein the rolling element comprises components that generates friction or internal friction when rolling. The rolling element has a soft or elastic surface. Due to the elastic surface of the rolling element is slowed down in its movement, which simplifies balancing. The friction can reduce the speed with which a balance board moves on a rolling body, which in turn simplifies the balance exercise.

In another exemplary embodiment of the balance training device, the spherical rolling element is adapted to deform when using the balance training device, or to press or compress flat and to produce a flexing work when unrolling. The spherical rolling element can optionally or additionally be filled with a viscous and / or non-Newtonian fluid in order to further increase the friction during unrolling. The rolling element is pressed flat during balancing, or compressed. A rolling upset ball comprises a larger contact surface and generates friction by varying circumferential lengths when rolling. In addition, a flattened rolling element produces flexing by deforming the outer layer. Other ways to create an internal friction may consist in a filling of a viscous or highly viscous material. It is possible to fill a ball with honey, syrup, glycerine, or even a vegetable, mineral or heavy oil. It is further contemplated to fill the rolling body with a filling of a non-Newtonian or abnormally viscous liquid. Non-Newtonian or abnormally viscous liquids can be used as rheopex or thixotropic liquids. A theopexy fluid liquefies upon exposure to shear forces and can facilitate an upgrade to the balance training device. When balancing, the theopexy fluid liquefies again, resulting in increasing difficulty in balancing. For example, a thezexe liquid may include ferric chloride hexahydrate and calcium carbonate in a polar solvent. Rheopex fluids solidify when shear forces occur. This means that an oblate deformed rolling body which is filled with a rheopexic liquid, performs only slow rolling movements, whereby balance exercises are simplified. Rheopex fluids are known, for example, as mixtures of corn starch and water. With all these parameters described above, a person skilled in the art can set the internal friction of the rolling body almost arbitrarily, whereby a balance behavior of the balance training device can be set almost arbitrarily.

In an additional exemplary embodiment of the balance exerciser, the spherical rolling element is hollow, filled with fluid, and provided with an inwardly projecting structure that impedes or impedes easy flow of the fluid. The spherical rolling element has, for example, inwardly directed nubs that at prevent a ball filled only half with a liquid from flowing along only a bottom of the interior of the ball without contributing to internal friction of the ball. This embodiment can be combined in particular with fillings of viscous liquids. In this embodiment, a hollow ball-shaped rolling element may be internally only partially filled with a viscous liquid or a non-Newtonian liquid. Partial filling of a hollow body is necessary to ensure flow of the viscous liquid. The ball may also include a foam layer to increase friction on the surface of the ball as it rolls off. The ball may also include a foam core to increase the internal friction of the ball when rolling. It is also contemplated to use a ball of foam, which preferably comprises different foam layers, each having a different elasticity or a different internal damping.

In another exemplary embodiment of the balance training device, the spherical rolling element is designed as a ball having an internal pressure of between 0.05 and 0.6 bar, preferably between 0.1 and 0.4 bar and more preferably between 0.15 and 0 , 2 bar above ambient pressure. The actual pressure conditions depend on load on further parameters such as load of the ball, degree of filling of the ball, the respective contact surface, the type of filling and the stiffness and thickness of the ball skin.

In an additional exemplary embodiment of the balance training device, it further comprises a handle on which a exercising person can hold his hands while exercising. The handle can be attached directly to the plate. The handle, if it is attached directly to the plate, have the shape of a bicycle handlebar. The handle, which may be designed as a support rod, may also be attached to a wall or a ceiling of a room in which the balance training device or the plate of the balance training device is located. The handle makes the device much easier to use. It is easier with the handle to train the upper body more with balance exercises. It is also intended to arrange the handle between 20cm and 250cm, between 30cm and 100cm, between 50cm and 80cm or 60cm and 70cm above the tread. It may be provided a corresponding connection element to ensure the distance to the plate or the tread. It is also envisaged to place one or two handles at a height of between 130cm and 220cm to be able to train, for example, sports such as windsurfing, kitesurfing, kite buggy riding and the like where the handles are placed quite high above a tread , The handles can also be adapted to the controls of the corresponding sports. It may also be provided for one or more attachment points for a trapezoid, which are mounted approximately in or on the chest of the training device. The handle may be rotatably mounted, for example, at the connection point on the tread surface in the longitudinal direction. A pivot point of the handle or handlebar can also be provided in the connecting element or directly on the handlebar. This version can be used for balance exercises for windsurfing, wakeboard or stand-up paddeling. A balancing with the hands to the right and left is possible because the connection in this direction is rigid. It may also be provided to provide a transmission which causes a lateral inclination of the connecting element on a rotation of the connection point on the tread surface to the left or right.

The handle or the handlebar may be rotatable or laterally pivotable as in a bicycle or motorcycle. The force for performing the rotational movement could be adjustable by using a separate damping element similar to a steering damper as in a motorcycle.

The handle may be designed to be displaceable in a direction substantially perpendicular to the plate or tread. In this version, the handle or the handlebar, similar to a fork in the mountain bike can be moved up and down. Again, a resistor and a damping can be performed adjustable.

It is also possible to attach the connecting element elastically or movably on the tread, so that small movements are possible. Such elastic coupling can further increase the difficulty of a balance exercise. It is possible to make the entire connecting element elastic.

In another exemplary embodiment of the balance training device, the handle may be designed to be foldable in order to make it easier to stow the balance training device. Lockable hinged joints are well known in the art, for example, folding or folding wheels and folding scooters. It is also envisaged to make the handle adjustable in the longitudinal direction in order to better adapt the balance training device to the body dimensions of a person exercising.

In another exemplary embodiment of the balance training device, this includes a display, sensors, and a communication interface. This can be during a workout Values such as reaction times, sizes of the movements (amplitudes) or the duration of a training session are recorded or specified. The sensors can be designed as acceleration sensors. The sensors may also include gyro and compass sensors. It is also contemplated to arrange heart rate and pulse sensors on the handle. It can also pressure and force sensors are arranged on the handles and the tread. Depending on the design of the sensors, both the training and body parameters of a person exercising can be recorded and monitored, and the display can serve to train one exercising person during a training session It is also possible to transmit the data transfer interface wirelessly, for example, and to transfer the data to a data processing system during a training session via a data transfer interface For example, the transmitted data may be used to control a television or a large monitor to output training-related data, graphics or other display output In this way balancing movements can be supported in a direct or indirect way by means of another output device such as a screen or via loudspeaker feedback on the execution of the balancing. It is also envisaged to switch off or impair an otherwise important for a balance exercise sense by an appropriate signal output, for example, to hone reflexes with respect to the other, unimpaired senses. For example, on a display, a film could be shown to suppress compensatory movements based solely on the sense of sight and promote compensatory movements based solely on the organs of balance.

It is also intended to arrange a recording for a smartphone, a game console or an input device of a game console on the balance training device. A smartphone that is equipped with the usual acceleration sensors, can be used by a simple application program as a training aid. Similar to well-known programs such as "Runtastic ™", training parameters can be relatively easily monitored.It is also possible to attach a modern game console with an acceleration sensor to the balance training device, whereby a game can be played on the game console by the movements of the balance training device For example, the motion-sensitive input devices of a "Nintendo ™ Wii ™, Wii-U ™, or Wii-Fit ™" on a "Sony ™ Playstation ™ 2-4" or an "Eyetoy ™" can be Move ™ ", or a" Microsoft ™ x-box ™ 360 ™ or Kinetic ™ "or the like to combine with the balance training device.It should be possible at least sports games such as skateboarding, cycling or water sports games with an input device control modern game console attached to the Balance Training device. It is also intended to make the handle of the balance training device adjustable in height so that, for example, a person can easily adjust a weight distribution between the handle and a tread. Preferably, the handle is provided with a receptacle for a smartphone or a screen. An acceleration sensor of a smartphone can be used to log the training. An acceleration sensor attached to the training device (and which may be located in a smartphone) may log response parameters of the exercising person and determine a training progress.

In another exemplary embodiment of the balance training device, the rolling surface is provided with a central recess. The central recess defines a Mittenbzw. Rest position of the spherical rolling element. The recess has a diameter which is about 1/4 to 2/3 times as large as the diameter of the rolling element. The recess may also have a diameter which is about 1/2 to 1/3 times as large as the diameter of the rolling element. The recess can also be designed as a through hole. The depression may also be non-circular, angular, star-shaped or stepped. The recess can also be designed as a through hole. More preferably, the recess or the through hole is not greater than 1/3 of the diameter of the unloaded rolling element.

The central depression or "sweet spot" may help to center the rolling element for stepping on the balance training device, thereby facilitating the entry of the balance training device, and this depression has a weak effect on a spherical rolling element inflated ball, which performs a large flexing work and whose height is greatly reduced by the load of the exerciser and the exercising person, is very weak, ideally the well has a shape that is complementary to a shape of an unloaded rolling body If the rolling body flattens under load, the effect of the recess is considerably reduced Depending on the diameter, the central recess can be used as a climbing aid or as a centering aid.

The "sweet spot" can be used to simplify the beginning of a balance exercise, ie the movement from a static position into the balance, and it can also be provided that the depression, ie the "sweet spot", is also controlled by a control element such as a brake lever , Here similar retractable feet claws, railings or fences or just other limiting elements could be extended, which is a rolling of the rolling element on the rolling surface Restrict Upper Prevent. In contrast to the movable boundaries, the claws, railings or fences or other limiting elements are not mobile, and can only be moved or retracted remotely to facilitate starting an exercise. The claws, railings or fences or other limiting elements can be operated, but are not movable in the sense that they can move alone under the action of gravity, with a change in position of the plate. As soon as balancing is started, the claws can be retracted and the rolling element can roll freely over the rolling surface. Of course, other mechanical solutions are conceivable with which the depression could be leveled, for example. It is also possible to fill the recess with an elastic material.

In an additional exemplary embodiment of the balance training device, the boundary for the spherical rolling element includes flaps. The flaps can fold in the direction of a center of the plate. As the edge of the balance training device panel approaches the ground, the flaps closest to the floor can fold in and allow the flap to touch the edge rather than the ground. The flaps can simply be made as strips that are hinged at the bottom so that they can fold in when loaded from outside to inside and when loaded from the inside, by the rolling element limit its movement. Flaps may be provided with recesses that allow the rolling element to extend partially into the recess. Due to the fact that the rolling element can at least partly move past the boundary, the rolling element is guided or guided in the direction of the center of the recess in a similar way as in a corner between two boundaries. As a result, not straight limiting behavior can be achieved with a straight boundary. It is envisaged to use multiple, divided or split flaps so that when the panel touches the leading edge, only one (front) portion of the flap retracts and a rear portion of the flap further limits movement of the rolling element. It is also possible to make the boundary as retractable surfaces or pins. If a pin is arranged vertically or outwardly inclined on the plate and is retractable in the axial direction, it can retract at a ground contact. An obliquely outward retractable pin, however, will jam in a lateral load by a rolling element when it presses against the pin. The pins should be arranged so that their mutual distance prevents the rolling element from rolling past directly adjacent pins.

A restriction of retractable pins or spring pins could be designed so that their heads are connected by a bar, a belt, a band, or ropes, etc. As a result, the boundary would form a kind of retractable railing, the whole or part of a ground contact could collapse or einfedern. A limitation in the form of a railing could also be designed as hinged railing. A limitation in the form of a railing could also include telescopically retractable stanchions. The boundary could also be executed as a folding frame. The boundary could also comprise several elements or individual flaps arranged side by side. It may also be provided to carry out the limitations as telescopic strips.

By way of example, it is also possible to make the limit adjustable in height in order to better adapt it to rolling elements with different diameters. Such an embodiment should allow a simple adjustment in order to minimize the "set-up times" or the preparation time for performing a balance exercise.

The boundary could, for example, also be elastically yielding, that is resilient in the direction of the movement of the rolling element, so that the rolling element is moved back towards the middle of the balance board when the rolling element hits the boundary.

In another exemplary embodiment of the foregoing balance training apparatus, the flaps, surfaces or pins are spring biased toward an extended position. This ensures that the flaps forming the boundary are always extended and can prevent the plate from falling off the rolling element. Alternatively or additionally, the flaps can be provided with rollers, rollers or rolling elements. The rollers, rollers or rolling elements can prevent the flaps from jamming when folding or retracting between the floor and the plate. The rollers, rollers or rolling elements can also reduce noise that can occur when placing the boundary on a floor. The rollers, rollers or rolling elements are arranged on an underside of the extended flap and put on a ground contact of the flaps on first. By the rollers, rollers or rolling elements can be prevented that the flap between the bottom and the plate pinched and affect the balance movements of the exercising person.

In another exemplary embodiment of the balance exerciser, the flaps, surfaces or pins may be locked in a retracted position. When the flaps are locked in a retracted position, the balance exerciser can be moved more easily without the handling of moving flaps or hamper a carrying. Preferably, the flaps, surfaces or pins are recessed in a retracted or retracted position in the plate.

In an additional exemplary embodiment of the balance training device, this further comprises a fixed point device. The fixed point device provides the exercising person with a fixed point to which the exercising person can concentrate. The fixed point device may be formed by a glue point. The fixed point device may comprise an object which is placed on the ground in front of the balance training device. The fixed point device may comprise a projector with which a fixed point is projected onto a floor or a wall.

The fixed point device can be designed as a glue point similar to Tesa, Velcro or Post-it, whereby the glue point can be attached to almost any surface. The fixed point device can also be made as an object that is simply placed on the floor in front of the balance training device. Preferably, a fixed-point object is made of a soft material, so that a person exercising abruptly breaks off a balance exercise and on the Fixpu nkt object occurs or falls on this is not injured. The fixed-point object can be designed, for example, as a rubber duck. It is also possible to implement the fixed point device through a projector with which the fixed point is projected directly onto the floor or a wall. A fixed point projector may include a laser diode or a small projector. A fixed point projector may also be coupled to an acceleration sensor and mounted to the board or handle, and acceleration sensor data may be used to compensate for any movement of the balance training device to hold the projected fix point in place ,

In another exemplary embodiment of the balance training device, it further includes feet that are disposed at corners or edges or at the bottom of the balance training device. The feet are preferably made elastic, so that a placement of the plate is damped on one or more of the feet. Elastic feet reduce the strain on the person exercising and on the ground. The feet can be made extendable. In the case of extendable feet, these can be controlled from the handle or extended and retracted. The feet may also include tennis balls or other hollow bodies attached to the corners, which allows for a particularly gentle placement of the feet on a floor. The feet can be controlled via brake levers and Bowden cables, as they are known from the bicycle industry. Such an embodiment would greatly facilitate boarding because the extended feet can not be retracted until after getting on. It can also be provided to retract the feet by means of hydraulic technology, as is also known from bicycle construction. It may also be provided to use electrical actuators for retracting and extending the elastic feet. The feet may be provided with various joints, which ensure either a safe and quick retraction and / or a safe and quick extension. The extension of the feet is more complex, as the plate may need to be raised.

The feet can have a spring effect. Sprung feet can store energy that aids lifting of the balance board when starting a balance exercise. Being able to store this property of the feet is also useful if a user needs to dismount uncontrollably or break off a balance exercise. The resting on the floor plate is then cushioned by the feet. A user can actively use spring-loaded feet, such as a trampoline, to bring the plate from an oblique rest position to a horizontal balance position.

With height-adjustable feet, in conjunction with the dimensions of the rolling surface, the balance board and the diameter of the rolling element, the minimum and maximum tilt angle of the balance board can be adjusted.

The feet should be 3 to 4 times smaller than a diameter of the rolling element. With a rolling element with an unloaded diameter of 16cm, 17cm, or 21cm, feet with a height between 5 and 7cm have proven to be useful.

It may also be provided to use height adjustable feet that can be adjusted by the handle in height.

The feet can be designed as small fillable hollow body. With hollow body feet, the air pressure can be varied and thus the compliance or spring property can be adjusted. A fillable foot can also be adjusted in height by the amount of filling. In yet another exemplary embodiment of the balance training apparatus, the boundary in a fully deployed position extends farther away from the panel 4 than the feet. Thus, the boundary is on the ground when the edge of the plate of the balance training device rests on a floor. However, when the plate rests on the rolling body, with the feet fully extended or extended, only the rolling body and the feet of the balance training device can rest on the ground.

In an additional exemplary embodiment of the balance training device, the rolling surface at the bottom of the plate is provided with an elastic material. The elastic material of the rolling surface can further influence the balance behavior of the balance training device by an internal friction. The greater the internal friction on the rolling surface of the plate, the easier it is to balance on the balance training device as the movements are more damped. The rolling surface may also be provided with an elastic material having a gradient of elasticity or internal friction towards the center of the rolling surface. The gradient makes it possible to make an edge more elastic, so that balancing in the region of the edge is simplified. Thus, with a gradient material or with several different materials of different elasticity, a balance behavior can be achieved which prevents a balancing person from having to break off an exercise due to a contact of the rolling element with the boundary. It is further provided to combine a rolling surface, which has a gradient of elasticity or damping, with a curved rolling surface or a thickness variation of the rolling surface. By a combination of a concave rolling surface and a material on the rolling surface which becomes more elastic towards an edge, it is possible to prevent the rolling element from sinking more strongly into the rolling surface at the edge, thus showing an unstable balance behavior. It may also be intended to use a gradient material which hardens outwardly to obtain a more sophisticated balance characteristic. Thus, the rolling surface can also be performed convex or the gradient material to be softer inside. The gradient material of the rolling surface preferably has a gradient on which in the direction of a center of the rolling surface directed circularly or polyhedrically decreases or increases.

In another exemplary embodiment of the balance training device, the rolling surface of the plate is concave. It can be provided that the rolling surface has a geodetic structure, that is composed of individual flat pieces. The rolling surface may also be slightly curved to cause the exercising person to hold the rolling body in the center of the plate. At the corners of the plate, similar to the playing surface of a table soccer table or a pinball machine, slants may be arranged to prevent the exercising person from getting caught on a corner of the plate. By the concave shape can make it easier for the user to keep the balance board in a balanced state. The boundaries may be arranged on the rolling surface so that the areas of the rolling surface, which make higher demands for balancing, can not be achieved by the rolling element. Such areas are the corners of the balance board, ie in the longitudinal direction front right and left and rear right and left. The boundaries can also form a combination with the feet, for example, by the boundaries are attached to the feet with joints.

It is also contemplated to provide rigid barriers that could be secured to the panel to restrict a possible rolling area of the rolling member. The rigid barriers are provided in addition to the movable limits to facilitate beginners to start training with the balance training device according to the invention. For example, the rigid barriers can only be balanced in a lateral direction or only forward or backward. Even when using the rigid barriers, the mobility of the movable boundaries should not be restricted. The rigid barriers can be rigidly mounted in various positions and at different distances in the area of the rolling surface.

In another exemplary embodiment of the balance training device, this includes a pad of elastic material. The pad of elastic material makes it very easy to change the internal friction of the system balance training device. Thus, simply by changing the pad a degree of difficulty of the balance training device can be adjusted. Depending on the elasticity, internal friction, surface structure or thickness of the pad, it is easy to change the damping balance training device without having to change other components of the balance training device.

It is further contemplated to use a pad or rolling surface comprising erected fibers. The base or the rolling surface may be provided with a carpet. A carpet with upright pile or with upwardly directed bristles can cause a rolling over rolling element is additionally offset or moved. This effect occurs when the rolling element rolls over bristles and thereby the bristles laterally turn over and thereby displace the rolling element easily. Depending on the length, orientation and stiffness of the carpet bristles, a greater or lesser offset across the carpet may be achieved. Through the carpet, a certain slip between the rolling element and the base can be achieved. It may also be provided to lay the rolling surface with a carpet in order to achieve a slip between the rolling element and the rolling surface. It can continue be provided to provide the rolling element with a surface comprising erected fibers.

In an additional exemplary embodiment of the balance training device, this is provided with pedals and or a crank. It can be provided that the crank is executed braked. The pedal can also be equipped with an ergometer, which can train a training of pedaling on a bicycle. In this version, the balance training device is particularly suitable for the bicycle trial sport, since here also the effects of pedaling or different foot positions can be practiced on the balance.

In an additional exemplary embodiment of the balance training device, this is provided with a bicycle or unicycle saddle. Since the balance training device can be used to train cyclists, it is also intended to replicate the other human-bicycle interfaces on the balance training device. It may also be provided to provide the crank with a braking device as an ergometer. Furthermore, provision may be made for arranging sensors on the pedal crank in order to determine a power output of an exercising person.

In another exemplary embodiment of the foregoing balance training apparatus, the inclination of the pedal crank, the saddle, and / or the handle may be changed by a position of the handle. In this embodiment, the handle can be designed as a bicycle handlebar. The bicycle handlebar, the crank and the saddle can be mounted on a common frame whose lateral inclination can be changed by a steering handle. This complicated embodiment may be provided with retractable feet, which can be extended or retracted via an operation of brake levers. In this embodiment, a "steering" of the handlebar can cause a side tilt of the pedal and the saddle, which compensating movements not only by a person's weight shift, but also by a steering movement are made possible by retractable feet can be the beginning of a balance exercise and thus the transition from a static position to the movement of a balance, even when the person is sitting on the saddle, can be made easier by the retractable feet, from a position in which he has lost his balance back into the With the help of a separate mechanism, it is possible to change an inclination forwards or backwards through a position of the pedals or a crank, so that balancing could only be achieved by means of a handlebar position and a pedal position. By executing elements of the balance exerciser described above, the degree of difficulty of the balancing can be adjusted and thus the user can be brought to balancing. In addition, the level of difficulty can be further increased to prevent the training device is too quickly uninteresting.

In an exemplary embodiment, the balance training device further includes elastic feet whose elasticity can be adjusted. As a result, the Aufsetzverhalten the plate can be adapted to Abrollkörper with different diameters and to trainers with different weights. This can be achieved, for example, with hollow feet that can be filled with a pressurized fluid. If the hollow feet are made of a stretchy material, it can also be used to adjust the height of the feet. If the feet are made of a non-stretchable material, only the elasticity of the feet can be adjusted by the pressure. Furthermore, the feet may be interchangeable or include an adjustable spring element.

In one embodiment, the balance training device comprises a pillar with a receptacle for a bicycle handlebar and / or a stem or a bicycle stem. This allows a person to use the handlebar of a bicycle or his bicycle for training with the balance training device.

In another embodiment of the balance training device, this comprises at least two handles on which a trainee can hold his hands when exercising, with the handles attached to the plate, and at a distance between 20 cm and 250 cm, between 30 and 100cm, 50 cm and 80 cm or preferably between 60 cm and 70 cm above the tread are arranged. The handles can represent, for example, ski poles.

In a further embodiment of the balance training device includes these handles that are adjustable in height, longitudinal, transverse and / or inclination. As a result, the handles can be adapted to a person exercising and to a sport to be trained.

In an additional embodiment of the balance exerciser, the handles are resiliently coupled to the plate. This allows the adaptation of the balance training device to sports, at the handle is elastically connected to the tread surface like (wind) surfing. Furthermore, this embodiment allows additional training of the arms while a balance training is performed. The handles can also be braked for more effective training.

In an additional exemplary embodiment of the foregoing balance training device, the limit for the rolling element is made resiliently. Due to the elastic design of the boundary, this can dodge a little during contact with the rolling element, as a result of which the rolling element is stopped less abruptly. A person exercising on the tread can continue the training because the impulse that results from the impact of the rolling element on the boundary is less pronounced, and the exercising person is not so unbalanced that he / she would have to break off the balance training. This allows a person exercising longer on the device to train, even if it occasionally bumps against the boundary with the rolling element. For this purpose, the limitation can be carried out elastically, wherein the entire limit yields. It may also be provided that the boundary is partially sprung in order to give way to a certain area. It can also be provided to carry out the limitation as flaps made of a flexible material, wherein the flaps can deform in whole or in part in order to make the limiting characteristic soft.

In another exemplary embodiment of the balance training device, the spherical rolling element is designed as a ball having an internal pressure between 0.15 and 0.3.

In a further exemplary embodiment of the present invention, the rolling surface comprises a soft material which allows the balance training device to be used with a substantially inelastic ball, the elasticity of the rolling surface being the balancing work to be performed during balancing and thus the damping of the rolling movement certainly. Preferably, the material comprises a plastic based on a non-Newtonian gel such as D30 or the like. More preferably, the soft plastic material is removable and / or replaceable.

The Figures are merely schematic and non-scale representations of embodiments of the present invention. Like reference numerals are used to refer to the same or similar components throughout the figures and the description.

FIG. 1 shows a plan view of an embodiment of a balance training device 2 according to the invention. In this basic embodiment, only the tread surface 4.1 of the plate 4 of the balance training device 2 is directly visible. The plate 4 rests near its center on a rolling element 8. Below the plate 4 four feet 10 are arranged, on which the plate 4 can rest, if no rolling element 8, which is designed here as a ball, is located under the plate 4. The rolling element 8 can only move in the limited by the limitations 6.1 to 6.4 rolling surface. It can be seen in the figure that the boundaries 6.1 to 6.4 need not be arranged directly on the edge of the plate 4. The boundaries 6.1 to 6.4 are movable and can fold in the direction of the center of the plate 4, which is not apparent from the figure 1 yet. FIG. 2 schematically shows a side view of the balance training device in an unloaded state in FIG. 1. The plate 4 rests on the rear feet 10 and the unwinding device 8. The rolling element 8 is not deformed by the schematic illustration. The boundaries 6.1 to 6.4 are designed as flaps and can, as indicated by the arrows, fold in towards the center of the plate. In the side view and the rolling surface 4.2 of the plate 4 is marked. FIG. 2 shows that the boundaries 6.1 to 6.4 protrude farther from the plate 4 than the feet 10. The feet 10 are shown as round elements. The feet 10 may also be formed by tennis balls or other elements.

Figure 3 illustrates the side view of the balance training device of Figure 1 in a loaded condition. The rolling element 8 is flattened and all feet 10 of the balance device are raised off the ground. Now, when the plate 4 tilts forward, and thereby moves forward, the movable front boundary 6.1 can fold backwards, so that the elastic front feet can cushion a touchdown on the ground. In contrast to FIG. 2, the limiting flap 6.3 is provided with a cutout which allows the rolling element to continue to roll outward in the region of the cutout. The rolling element can move into the cutout with part of its round surface. Through the neckline can be balanced in the middle of the left edge until further to the edge. Through the cutout, the rolling element is glided in the direction of the center of the cutout or the recess. The cutout is intended to prevent the rolling element rolling along the boundaries towards the corners where two boundaries meet and where balancing is more difficult. It is also intended to provide further or all limitations with such cutouts. The shape of the cutout can be adapted to the shape of the rolling element 8 and in particular to the shape of a loaded rolling element. The limiting flap 6.3 can also be designed as two separate non-interconnected flaps, wherein the front and the rear part can fold inde pendent of each other, and wherein the two parts are separated by the cutout.

Figures 4 and 5 show isometric views of another embodiment of a balance training device according to the invention. In addition to the known features of the retractable boundaries 6.1 to 6.4, the plate 4 is provided with a central recess 12 for a "sweet spot" for ball fixation.The diameter of the central depression or opening 12 is shown to be too large, since it is almost as large. as the visible under the plate 4 rolling element. 8 FIG. 6 shows an embodiment of a balance training device 2 according to the invention with a handle 18 attached to the plate. This design is used in particular to also use the hands and arms when balancing. Depending on the position of the handle, more or less load can be applied to the plate. The handle 18 is designed here as a bicycle handlebar. The bicycle handlebar is attached to a connecting element 16 on the plate. The handle may be for balance exercises with bicycles, for example, at a height of 60 to 80 cm above the plate 4 and the tread 4.1.

FIG. 7 shows an embodiment of FIG. 6 on a substrate. Depending on the strength or the surface condition of the substrate, various rolling properties can be achieved. In general, the softer the pad 22 is made, the easier it is to balance the balance exerciser. The pad 22 may be placed on a moving surface 20, which ensures that the pad 22 can not slip relative to the bottom 42.

FIG. 8 shows an embodiment of a balance training device according to the invention with a handle attached to a wall of a room. The handle may also be attached to a wall 46 or ceiling 44 (not shown) of a room by means of a wall / ceiling fixture 30. Again, the handle 18 affects the balance characteristics significantly. It is clear that the balance characteristics can change significantly depending on the mounting point of the handle.

FIG. 9 shows an embodiment of a balance training device according to the invention with a handle attached to a frame. A frame 32 provides the attachment point for the handle 18 in FIG. In this embodiment, the balance device 2 can be used with the handle 18, which is attached to the frame 32, also outdoors or in halls. The frame 32 may additionally be padded in order to be able to catch a person falling down from the balance device 2 without being injured.

Figure 10 shows a partial sectional view through a possible embodiment of a flap designed as a limit. The partial section passes through an edge of a plate 4. The tread of the plate is located in the image above. The section 6.3 represents a hinged lateral boundary. The solid line represents the boundary 6.3 in a folded and locked state. The boundary is recessed in the underside of the plate 4. The 6.3 limit can pivot about the axis of rotation of the boundary 88 and fold down. The unfolded position is indicated by the dashed line to the reference 6.3. in the In the unfolded state, stop 86 prevents the boundary from opening further. The 6.3 limit can not be fully extended to 90 degrees to ensure that the flap or limit 6.3 can fold in automatically when a force is applied from below. To ensure that the flap remains unfolded even with rapid balance movements, a coil spring or clock spring is provided as a biasing spring 84. This biasing spring is intended to hold only the paw to the outside, so that the abutment surface 86 of the restricting flap 6.3 rests against the corresponding surface of the plate 4.

At the lower end of the Begrenzungskla ppe 6.3 a drehba re role 80 is attached. The roller 80 ensures that the edge can not jam when placed on the floor. By the roller 80, the flap 6.3 can be folded in the direction of a retracted position, without the balance process is greatly affected.

FIGS. 11 to 13 show various developments of the embodiment shown in FIG. In Figure 11, the Ba lance Tra iningsvorrichtung with a Ha age 50 for a sma rtphone or an input device provided. The holder 50 for a smartphone or an e ingabegerät for example, a game console can be used to make a balance exercise interesting n or r or entertaining. As Einga begeräte for computers or game consoles are in particular those with acceleration nigu ngs- and gyroscopes. Thus, you can train in front of a TV in front of a virtual environment. In such an application, a kind of "Artificial Horizon" can be represented, which simplifies the balance exercises.

In FIG. 12, the balance training device is provided with a display 52, with sensors 54 and a data transmission interface 56. The sensors may include pulse sensors, blood pressure sensors, position sensors, gyro sensors, force sensors (for the feet or hands of an exercising person) or attitude sensors. Thus, the balance training device can also be used as an input device for a game console. It may also be provided to allocate a computer to the balance training device a, so that the balance training device comprises a complete game console or a complete training computer.

In Figure 13, the balance training device is shown with retractable or retractable feet 60. The feet 60 can be operated via an operating element 58 for the folding / unfolded feet from the handle 18. As shown, the collapsible feet 60 can be remotely controlled via a type of brake handle known from bicycles. This can cause a person put on the tread 4.1 and retract the feet 58 with the handle. It is also possible to provide the feet with a mechanism that allows a foot to fold in or out under load. It is shown here only a very simple example with (too short) laterally foldable feet to illustrate the principle schematically.

FIG. 14 illustrates a foot position during balancing that corresponds to the posture of a cyclist. Due to the height of the handle and a corresponding foot position, a balancing person can achieve approximately the weight distribution between the hands and the feet, as it corresponds to that of a mountain bike. The balance movements, however, differ significantly, since the fulcrum is firmly connected to the earth in a bicycle and in the balance training device lateral translation movements are possible. The balance training device can be used to exercise balance movements on bicycles in which the crank is in a substantially horizontal position. It may also be provided in general, the positions of the feet for various sports such as cycling, monoski, and the like are marked. The tread can also be provided with an anti-slip coating.

Figures 15 and 16 show an embodiment of a balance training device according to the invention, which is provided with a handlebar a saddle and with pedals, wherein the inclination of the handlebar, the pedals and the saddle can be influenced via a steering position of the handlebar. On the plate 4, a kind of frame is arranged, which carries the handle 18, the pedals or the pedal crank 70 and a saddle 72. The frame can now be inclined on both sides about an axis which runs parallel to a longitudinal axis of the plate 4. The handle 18, which is designed here as a handlebar, is mechanically coupled with a movement in the side slope. When the handlebar is turned sideways, a corresponding mechanism causes a lateral tilting movement of the frame. With the frame, the pedals or pedal crank 70 and the saddle are tilted to the side. This allows a person who sits on the saddle and put his feet on the pedals balance over a steering angle of the handlebar in the lateral direction.

It may also be provided that the pedal crank 70 and the pedals are connected via a reduction gear with the plate 4 to tilt the plate relative to the frame forward or backward. In this embodiment, a cyclist could use all the elements he knows about a bicycle, such as handlebars, pedals, and saddles, in addition to his body weight in a balance exercise. It is also possible other sports equipment mount accordingly on the plate 4 and to control an adjustment of the inclination of the plate bezüg the sports equipment by an operation of the sports equipment by the user.

Instead of bicycle controls also other sports equipment or elements of sports equipment can be mounted on the plate. It can be provided, for example, to mount foot straps of snowboards or ski bindings on the plate. It may also be provided to arrange the ski bindings on straight or curved slide rails, for example, to be able to perform a frond or cross-country movement during balancing. It may also be provided to arrange pedals or footstraps on laterally tiltable elements in order to imitate a tilting movement of one foot when "curling" or cornering.

It is also conceivable, for example, to mount a windsurfing boom or a line guide for simulating kitesurfing, or kite (snow) boardening on the board or a separate frame. For kitesurfing exercises, a fastener or handle with a height of over 2.2 meters can be attached. It is envisaged to make additional attachments, handles or compounds of composite materials so as not to raise the center of gravity of the balance training device by the Anbauteiie too much.

It may also be provided to attach pedals to the plate which can be operated with the feet to either simulate a sports equipment or to control with the legs or feet of the user retractable folding feet or other elements on the balance training device.

It may also be provided to attach additional rigid boundaries to the plate to allow beginners to simplify an exercise by allowing the rolling element to roll over the rolling surface in one direction only. These additional limitations may be further adjustably mounted to slowly introduce a person exercising to all degrees of freedom of the balance training device.

It can also be provided to highlight preferred foot positions on the tread of the plate to mark the foot positions for practicing certain sports (see Fig 14). FIG. 17 shows an embodiment of a balance training device according to the invention with fixed boundaries and a handle. As in FIG. 6, the balance training device 2 comprises a plate 4 with a footing 4.1 on an upper side of the plate 4 and one on an underside of the plate 4 arranged rolling surface 4.2. The rolling surface rests on a rolling element 8 so that the balance training device can roll over it. As in FIG. 6, the balance training apparatus 2 further comprises a handle 18, on which a exercising person can hold on with his hands while exercising. The handle 18 is fixed to the plate 4 has a distance between 30 and 100cm, 50 cm and 80 cm or 60 cm and 70 cm to the tread. In contrast to the version with foldable borders, it is not possible to use the entire angle range during training here. Here the boundaries can also serve as feet at the same time.

FIG. 18 shows a bottom view of an embodiment of a balance training device according to the invention with a total of eight movable boundaries and a handle. The plate 4 substantially corresponds to the embodiment shown in FIG. In contrast to Figure 1, a total of eight movable boundaries 6.1 to 6.4 are arranged on the plate 4 and limit the rolling surface 4.1. The dashed lines show the limiting flaps 6.1 to 6.4 in a retracted position. The flaps or limitations 6.1 to 6.4 are designed in all versions so that they can fold or retract independently. The boundaries should be designed so that the individual movable boundaries can not interlock or interfere with each other.

The boundaries essentially form an octagon, with the leading edge forming a sort of bow, so that the rolling element is urged toward a center of an edge as the rolling element rolls toward an edge. It has been found that it is easier to start a balance exercise when the rolling element is in the middle of an edge and is not at a corner of a rectangular plate. Due to the angle arranged in an angle, the beginning of a balance exercise can be simplified. It is also envisaged to arrange the boundaries diamond-shaped. It is also contemplated to use 3, 5, 6, 7 or more movable limitations that can fold independently.

FIG. 19 shows a side view of an embodiment with lamellar-like movable boundaries. The boundaries are formed by hinged strips that can individually fold against one another. As a result, a boundary that rests on a floor fold in or retract in a simpler movement. The joints or Hinge straps that connect the individual strips together can allow movement of at least 90 ° to a maximum of 180 °.

It can be clearly seen in FIG. 19 that the boundary 6.3 is formed by two mutually independent partial boundaries. Through this construction, it is possible that, for example, a front part of the boundary 6.3 folds in or retracts sideways, while a rear part of the boundary 6.3 is prevented from collapsing or retracting by an abutting rolling element.

The gap in the boundary 6.3 can act in a similar way as the boundaries of FIG. 18 arranged at an angle to one another in order to guide the rolling element in the direction of a center of an edge of the plate or the gap.

The gap in the boundary 6.3 can also be used in a single-piece flap boundary to guide the rolling element towards a center of an edge of the plate or gap.

Regardless of the illustrated embodiments, the edge of the plate may be made soft or shock absorbing to avoid damage to objects or injury to persons. It may also be provided to provide separate shock absorber elements similar to bumpers on a car.

It should be noted that with the disclosed embodiments, all combinations of features of the various embodiments should be considered as disclosed. So it is intended, for example, retractable feet to combine an anti-slip coating or a smartphone holder with many different other designs. LIST OF REFERENCE NUMBERS
