EP3515393B1 - Device for vibration training - Google Patents

Description

The invention relates to a device for performing vibration training, with a platform, a first actuator which is set up to set the platform into a vibratory movement, and a second actuator which is set up to set the platform into a rocking movement.

Devices for performing vibration training are used, for example, in fitness sports, in rehabilitation or in physiotherapy to strengthen the muscles and to increase the ability to balance and coordinate.

In devices of the generic type, vibration movements of a platform are transmitted to a device user, the vibrations triggering muscle reflexes. The muscle reflexes cause muscle contractions. These muscle strains ultimately lead to targeted and intensive training.

In addition to conventional devices for performing vibration training, which have a platform that can be set in a vibratory movement, further solutions are also known from the prior art.

The pamphlet EP 1 541 112 A1 proposes a muscle stimulation and massage device which has a footplate, a column and a vibration unit. The column, which comprises two laterally spaced apart guide rail towers, each with at least one guide rail, stands on the base plate. A lift can be moved up and down the guide rails so that it can be moved to different heights in relation to the footplate and locked here. The lift has the shape of a U-shaped support frame. A vibration unit is attached between the open ends of the support frame.

From the pamphlet DE 20 2012 007 856 U1 a rocker with a base plate is also known, whereby the base plate can be moved in a rocking motion, two measuring sensors are integrated on the base plate and the stability of the base plate can be adjusted via rubber rings or springs and a vibration system is attached to the base plate based on the unbalance or eccentric principle which can be controlled via the function On, Off or by changing the intensity, depending on the tilt angle.

document DE 20 2007 008 887 discloses a device for training and / or analysis of the musculoskeletal system of a user, the device comprising at least one basic element which can be set into periodic and / or aperiodic movements by at least one drive device.

In these and other known solutions, however, the platform has a limited range of motion. Due to the limited number of types of movement, only one training of certain muscle groups can be implemented. In addition, the achievable training successes in terms of increasing balance and coordination are considerably limited by the limited number of types of movement.

The object on which the invention is based is thus to provide a device for performing vibration training which, compared to the known devices, enables more effective, more varied and / or more intensive training.

The object is achieved with a device for performing vibration training of the type mentioned at the outset, the device according to the invention having a third actuator which is set up to set the platform in a linear movement.

The invention makes use of the knowledge that, in addition to the vibration movement and the rocking movement of the platform, a linear movement of the platform can also be used to cause muscle reflexes. The muscle reflexes caused by the linear movement of the platform differ from the muscle reflexes caused by the vibration movement and the rocking movement of the platform, from which a changed muscle strain results. The training can thus be designed to be more effective, more diverse and / or more intensive.

In a particularly preferred embodiment of the device according to the invention, the third actuator is set up to move the platform back and forth. The linear movement of the platform thus comprises a movement of the platform along a linear movement path in a first direction and a movement of the platform along the movement path in a second direction, the first direction and the second direction being oriented opposite to one another. By changing direction, the stressed muscle groups are expanded and the training-related increase in the equilibrium and coordination ability of the device user is further promoted.

In an advantageous embodiment of the device according to the invention, the third actuator is set up to move the platform within an at least substantially horizontal plane. The linear movement of the platform, which is implemented by the third actuator, can thus implement an essentially horizontal oscillating movement of the platform. For example, the third actuator causes the platform to move alternately backwards and forwards. Alternatively, the third actuator can cause the platform to move alternately to the left and to the right. The movement of the platform within a horizontal plane leads to a considerable increase in balance and coordination training.

In another development, the device according to the invention is set up to simultaneously set the platform into the vibration movement and the rocking movement. As an alternative or in addition, the device can be set up to set the platform into the vibratory movement and the linear movement at the same time. The combination of the vibration movement and the rocking movement as well as the combination of the vibration movement and the linear movement results in a particularly effective training, with the combination of two types of movement causing muscle reflexes that cannot be produced when training with just one type of movement. The training success is thus increased again. In particular, the platform can also only be set in the vibration movement, the rocking movement or the linear movement.

In a further advantageous embodiment of the device according to the invention, the first actuator, the second actuator and / or the third actuator each comprise one or several electrically driven motors. The first actuator, the second actuator and / or the third actuator can preferably be connected to a power supply which makes electrical power available to the actuators. The one or more electrically drivable motors of the first actuator, the second actuator and / or the third actuator can, for example, generate a rotary movement or, as a linear drive, generate a translational movement. For example, the electrically drivable motors of the first actuator, the second actuator and / or the third actuator have a nominal power of 200 watts or 500 watts.

The first actuator preferably has one or more gears which convert a rotational movement of a shaft into the vibratory movement of the platform. Alternatively, the first actuator comprises a linear drive which directly generates corresponding vibrations. The platform is preferably deflected in the vertical direction as a result of the vibration movement. For example, the vibration movement has a frequency of 50 Hz or 60 Hz.

The second actuator preferably has one or more gears which convert a rotational movement of a shaft into the rocking movement of the platform. In particular, the rotational movement of the drive shaft of an electrically drivable motor or an intermediate shaft of the second actuator connected to the drive shaft of the electrically drivable motor is converted into an eccentric movement of a drive member by a gear before the eccentric movement of the drive member is converted into a linear movement by a corresponding joint, which is passed on to the platform. The direction of movement of the linear movement is preferably orthogonal to the platform and the drive member is connected to the platform at a distance from a horizontal axis of rotation of the platform. Because the direction of movement of the linear movement is orthogonal to the platform and the drive member is connected to the platform at a distance from the horizontal axis of rotation of the platform, the linear movement is converted into a rocking movement of the platform.

The third actuator preferably has one or more gears which convert a rotational movement of a shaft into the linear movement of the platform. In particular, the rotational movement of the drive shaft of an electrically drivable motor or an intermediate shaft of the third actuator connected to the drive shaft of the electrically drivable motor is converted into an eccentric movement of a drive member by a gear before the eccentric movement of the drive member is converted into a linear movement by a corresponding joint, which to the platform is passed on. The direction of movement of the linear movement is preferably parallel to the platform. Because the direction of movement of the linear movement generated runs parallel to the platform, the linear movement generated is passed on directly to the platform.

The first actuator, the second actuator and / or the third actuator can each have one or more belt drives. With belt drives, a transmission stage can be implemented in a simple manner, which at the same time has shock absorption and overload protection.

The device according to the invention is furthermore advantageously developed in that the platform is rotated back and forth by the rocking movement about an essentially horizontal axis of rotation. In particular, the axis of rotation runs essentially centrally from the platform. Depending on the orientation of the device user, different impulses can be generated so that the rocking movement enables targeted and effective training of certain muscle groups.

In a preferred embodiment, the device according to the invention has a control device which is set up to control the first actuator, the second actuator and the third actuator independently of one another. For this purpose, the control device is connected to the first actuator, the second actuator and the third actuator, preferably with their electrically drivable motors, in a wired or wireless signal-conducting manner. The desired types of movement of the platform can thus be set by the control device and the device can thus be individually adapted to the device user. Either different types of movement can be combined with one another or individual types of movement can be set in isolation.

In another development of the device according to the invention, the control device is set up to change the intensity, the speed and / or the scope of the vibration movement, the rocking movement and / or the linear movement of the platform. The handling of the vibratory movement includes the amplitude of vibration of the platform in the vibratory movement. The oscillation amplitude of the platform during the vibration movement is preferably between 0 and 2 millimeters. The scope of the rocking movement includes the angle of rotation of the platform during the rocking movement. The angle of rotation of the platform during the rocking movement is preferably between 0 and 10 degrees, the linear lateral deflection of the platform during the rocking movement preferably being between 0 and 13 millimeters. The scope of linear motion includes the Length of the movement path of the platform during the linear movement. The length of the movement path of the platform during the linear movement is preferably between 0 and 14 millimeters. The speed of the vibratory movement, the rocking movement and / or the linear movement can preferably be set continuously or in steps. For example, the speed of the vibration movement, the rocking movement and / or the linear movement can be set in 60 steps.

In a further embodiment of the device according to the invention, the control device can be operated wirelessly and / or wired by means of an electronic device external to the device. The electronic device external to the device is, for example, a personal computer or a mobile terminal such as a smartphone or a tablet. The control device can preferably be operated by means of a corresponding program on the personal computer or a corresponding application on the mobile terminal device. This means that the device can be easily and quickly adjusted to the individual requirements of the device user.

In a preferred embodiment of the device, the platform has a step surface which is set up to be stepped on by a device user. The step surface can also be set up so that the device user can lie down, kneel or sit on the step surface. Different body positions can be used to train different muscle groups with the device. Thus, the device can be used much more extensively and flexibly if the device user can adopt different postures on the device.

In a further advantageous embodiment of the device according to the invention, the platform is rubber or spring-mounted. With a rubber or spring mounting, the platform can be slightly deflected when the device user is subjected to a corresponding load. Since the platform thus yields when the device user is under high load and / or at high speed, the risk of injury when using the device is considerably reduced, since load peaks are avoided or at least weakened by the rubber or spring mounting.

In one embodiment, the device has a base plate on which the first actuator, the second actuator and / or the third actuator are arranged and preferably fastened. The base plate and the platform are, for example, each completely or partially made of plastic or metal. In that the first actuator, the second actuator and / or the third actuator are arranged or respectively on the base plate are attached, a high device stability is achieved. This allows the device to be changed in position or inclination without damage or malfunction. The device is therefore transportable and can be used in different positions or locations.

The device according to the invention preferably has one or more transport rollers by means of which the entire device can be moved. This overcomes the need to completely lift the entire device when changing position. A change in position of the device can therefore also be implemented by an individual, which considerably increases the convenience of use.

In another embodiment, the device according to the invention has a handle device by means of which the entire device can be lifted at least on one side. The handle device is preferably arranged on a first side of the device and the one or more transport rollers are arranged on a second opposite side. Thus, the handle device allows a comfortable one-sided lifting of the device, the one or more transport rollers being brought into contact with the floor surface by the lifting, so that the device can be moved.

It is also preferred that the device according to the invention has several feet, the height of one, several or all of the feet being adjustable. The adjustability of the height of one, several or all of the feet can be used on the one hand to level out uneven floor surfaces or on the other hand to adjust the inclination of the device. Because the device inclination can be adjusted using the feet, the device user can carry out further exercises with the device.

According to Fig. 1 For performing vibration training, the device 10 comprises a platform 12, a housing 14, a first actuator (covered), a second actuator (covered), a third actuator (covered) and a control device 58.

The platform 12 has a step surface on which a device user 100 stands on one leg and performs an exercise. A handle device 16, by means of which the entire device 10 can be lifted, is attached to the housing 14 of the device 10.

The first actuator is set up to set the platform 12 in a vibratory movement 18. The second actuator is set up to rotate the platform 12 back and forth in a rocking movement 20 about a horizontally running axis of rotation 62, the axis of rotation 62 running centrally from the platform 12. The third actuator is set up to move the platform 12 back and forth in a linear movement 22a, 22b within a horizontally extending plane.

The control unit 58 is connected in a signal-conducting manner to the first actuator, the second actuator and the third actuator and is set up to control the intensity, the speed and the scope of the vibration movement 18, the rocking movement 20 and the linear movement 22a, 22b of the platform 12 independently of one another and change. The oscillation amplitude of the platform 12 when executing the vibratory movement 18, the angle of rotation of the platform 12 when executing the rocking movement 20 and the length of the movement path of the platform 12 when executing the linear movement 22a, 22b can thus be set via the control device 58.

The control device 58 is connected in a wireless signal-conducting manner to an electronic device 60 which is external to the device and is embodied as a tablet. The control device 58 can be operated by means of a corresponding application on the electronic device 60 external to the device.

A plurality of rubber elements 30a-30f, through which the platform 12 is rubber-mounted, are arranged between the platform 12 and the intermediate frame 32. A handle device 16, by means of which the entire device 10 can be lifted, is attached to the base plate 34 of the device 10. Furthermore, there are several transport rollers on the base plate 34 of the device 10 36a, 36b, by means of which the entire device 10 can be moved. In addition, the first actuator 24, the second actuator 26 and the third actuator 28a, 28b are arranged and fastened on the base plate 34.

The first actuator 24 is set up to set the platform 12 in a vibratory movement. The first actuator 24 further comprises an electrically drivable motor 40. The electrically drivable motor 40 is designed as a linear drive and alternately transmits up-and-down movements to the platform 12.

The second actuator is set up to rotate the platform 12 back and forth in a rocking movement 20 about a horizontally running axis of rotation, the axis of rotation running centrally from the platform 12. The second actuator 26 comprises an electrically drivable motor 42, the drive shaft of which drives an intermediate shaft via a belt drive 44. The rotational movement of the intermediate shaft connected to the drive shaft of the electrically drivable motor 42 is converted into an eccentric movement of a drive member 46 by a gear mechanism before the eccentric movement of the drive member 46 is converted into a linear movement by a corresponding joint 48, which is transferred to the platform 12 via the intermediate frame 32 is passed on. The direction of movement of the linear movement runs orthogonally to the platform 12 and the drive member 46 is connected to the platform 12 at a distance from the horizontal axis of rotation of the platform 12.

The second actuator 28a, 28b comprises an electrically drivable motor 50, the drive shaft of which drives two intermediate shafts via two separate belt drives 52. The rotational movement of the intermediate shafts connected to the drive shaft of the electrically drivable motor 50 is converted into an eccentric movement of two drive members 54 by respective gears, before the eccentric movement of the drive members 54 is converted into a linear movement by corresponding joints 56. The direction of movement of the linear movement runs parallel to the platform 12. Because the direction of movement of the linear movement runs parallel to the platform 12, the linear movement is passed on to the platform 12 via the intermediate frame 32 without further deformation.

The device 10 also has four feet 38a-38d, the height of all feet 38a-38d being adjustable.
