Description

TITLE

"EXERCISE DEVICE"

DESCRIPTION

The present invention relates to an exercise device. More in particular, the invention relates to a device to be gripped, such as a barbell, a dumbbell, a medicine ball, or the like. Even more in particular, the invention concerns an exercise device for carrying out physical exercises mainly involving the muscles of the upper part of the body.

The invention falls within the sector of sporting equipment suitable to stimulate the reaction of the human body to so-called motor interferences, i.e. external stimuli that, during the performance of a movement, can generate a variation of the balance of a person.

Usually, training of the muscles of the body involves the performance of free body exercises or exercises with equipment (movable devices or stationary machines).

While performing these exercises, the person handles a device with a fixed centroid or with a fixed configuration for the whole of the exercise. The load of these devices is therefore described as stable.

A person training with these devices voluntarily contracts his/her muscles to carry out a given movement typical of the exercise being performed.

In practice, during the performance of an exercise, any variation of position or speed of a part of the body, just as the force exerted by given muscles, is known or in any case predictable by the person carrying out the exercise.

However, both in the practice of some sporting activities and in normal daily actions, our body is often subjected to external stimuli, predictable or unpredictable, that can interfere with a movement that is being performed or with a condition of stable balance. These interferences can be generated, for example, by a strong gust of wind or a sudden and unexpected movement of the axis of the body or of the weight of the object to be grasped. In general, the greater the rapidity and unpredictability of the interference that occurs, the more difficulty the body has in reacting correctly to re-establish the condition of movement, or of unperturbed balance.

In this regard, studies by Shumway-Cook A. and collaborators, Nasher L.M. and collaborators, and Mollroy and collaborators show that this capacity of our body to react can be developed and increased with a training method in which motor interferences are suitably imparted to the person during the performance of physical exercises.

Today, this capacity is developed, for example, by means of proprioceptive equipment such as platforms, boards or the like, which however act prevalently on the balance of the lower limbs.

However, in many sporting disciplines, but also in rehabilitation, it is necessary to develop these capacities to react also, or prevalently, for the torso and for the upper limbs.

For the aforesaid purpose, there are known devices that, directly or indirectly, exert a variable or unstable load on the body of the person performing the exercise.

WO 2005/075026 Al discloses a device that comprises a flexible casing partially filled with a liquid and/or with loose solid particles, such as sand or the like. The outside of the casing is provided with one or more handles, or grips, for grasping the device and moving it when performing exercises.

During the movement, the liquid or the loose solid inside the bag moves, continuously varying the centroid of the device, and thus influencing the stability of the person performing the exercise.

Similar known devices are described in US 2014249002 Al, US 891 1334 Bl and GB 2388049 A.

Nonetheless, these known devices, thus configured, have some limits. The instability generated by the movement of the liquid or solid material is in fact influenced both by the position of the device and by the speed with which it is moved while performing the exercise. For example, if the device is moved rigidly in space, the liquid could remain substantially in the same position, without influencing the position of the centroid. Therefore, with the aforesaid known devices the destabilizing effect is, on the one hand, difficult to control, as it is not possible to manage the movement of the material inside the casing, and, on the other hand, is in any case at least partly predictable, as the person can sense in which direction the material will move as a function of the position taken by the casing.

There is also known equipment that can be gripped, comprising a vibrating element, generally activated by electric motors, capable of exerting, through mechanical vibrations, neuromuscular stimulation aimed at strengthening or rehabilitating the muscles of the upper part of the body. Examples of these devices are described, for example, in WO 2010/123374 Al , WO 2012/056483 Al or DE 102010050893 Al .

These known devices, during use, thus emit vibrations generated by the continuous movements of the vibrating element, of rotational or translational type, at a given fixed or adjustable frequency. The aforesaid frequency, in these known devices, is directly proportional to the number of revolutions that the vibrating element carries out about the axis of rotation, if the movement is of rotational type, or to the number of movements that the vibrating element carries out between two end points of a linear path, if the movement is of translational type. In order to carry out effective muscle stimulation through the vibration, the movement of the vibrating element of these known devices has a frequency generally comprised between 30 Hz and^" 50 Hz.

Moreover, in these devices, the mass of the vibrating element is calibrated to cause rapid contractions of the muscles of the person without however varying the centroid of the device to any great extent. In fact, these devices are conceived to perform exercises in stable static position or to perform conventional exercise in movement, in which the stimulation caused by the vibration is added to the stimulation caused by moving or lifting of the device.

In this context, the object of the present invention is to propose an exercise device that overcomes the aforesaid limits of the prior art.

The main object set and achieved with the present invention is to provide an exercise device that allows a person to perform a physical exercise perturbed by motor interferences that are unexpected and that change in an unknown manner.

In particular, an object of the invention is to provide an instrument capable of generating motor interferences that cannot be controlled, or can only partially be controlled, by the person during the performance of the exercise. The object of the invention is also to produce an exercise device that allows greater freedom in the performance of exercises, as the aforesaid motor interferences are independent from, or dependent in a controlled manner on, its position or its movement in space.

The purpose of this device is, therefore, that of reproducing motor interferences to which a person in daily life, or an athlete during the performance of a sporting activity, could be subjected.

Another object of the present invention is to produce a versatile device that can be used for professional or amateur training, for various sporting disciplines or for rehabilitation.

Yet another object of the present invention is to provide a practical device that can also be used by beginners or inexperienced users.

The aforesaid objects are achieved by an exercise device that can be gripped by a user, or in any case associated with a part of the user's body, to perform static or dynamic exercises. The device according to the invention is equipped with at least one movable mass that during the performance of an exercise is subject to sudden movements (rotations and/or other movements) and, therefore, potentially destabilizing for the balance of the person performing this exercise. The movements and/or the rotations of the mass are imparted by actuator means controlled by a control unit that activates and deactivates the aforesaid actuator means in sequence with a frequency such as to generate motor interferences.

This configuration allows a more or less rapid activation of the actuator means, which by moving the mass, and therefore the centroid of the device, unpredictably, can create conditions of imbalance that are more unexpected with respect to those of prior art devices.

The movement of the mass thus generates an imbalance of the body of the device that must be offset by the user to reinstate the movement being carried out or the stable position being held, during performance of the exercise.

Advantageously, the sequence of the activations and deactivations can be programmable so as to generate a sequence of motor interferences as a function of the type of training required and/or of the prowess of the person using the device.

Again for this purpose, the mass can be substituted with others of different weight. According to a first aspect of the invention, the exercise device comprises:

at least one body that can be gripped or can be connected to a gripping means or to a part of the body of a person;

at least one movable mass connected to said body so as to be able to carry out a rotational or translational movement, or both;

- actuator means for moving said mass; and

a control unit that controls said actuator means.

According to the invention, the control unit is configured to activate and deactivate said actuator means according to a specific sequence that causes respective movements of the mass. These movements cause a variation of the centroid of the device such as to generate motor interferences for the person using it.

In particular, the aim of the control unit is to decide the instants in which the actuator means are to be activated and deactivated, and therefore the duration of an activation cycle, the rest or deactivation time between one activation cycle and the next and so forth for a given number of cycles.

According to an aspect of the invention, the duration of an activation cycle can be such as to allow the mass to carry out a wider or narrower movement, for example only part of a rotation cycle or of a movement between two ends, a complete cycle or several complete cycles. In general, a partial or complete cycle of rotation or movement can be sufficient to cause the destabilizing effect for the person using the device.

According to a preferred aspect of the invention, the rest or deactivation time between one activation cycle and the next differs at least from the previous time, so that the movement of the mass, and consequently the unbalancing event of the device, is not expected or anticipated by the person using the device.

According to an aspect of the invention, these intervals of time are random. They can be generated in real time by the control unit, during use of the device, or they can be stored in a memory of said control unit.

According to another aspect of the invention, the frequency between one activation event and the next is preferably comprised between 0.02 Hz and 5 Hz and more preferably between 0.05 Hz and 1 Hz. In other words, the time between one activation cycle and the next can vary between 0.2 seconds and 50 seconds and more preferably between 1 second and 20 seconds.

Within the scope of the present invention, the term frequency thus refers to the activation and deactivation sequence of the actuator means, and not to the number of rotations or movements that the mass carries out in a given interval of time.

According to an aspect of the invention, the control unit is configured also to vary, adjust or control one or more of the following parameters concerning the movements of the mass, i.e. acceleration, speed and amplitude. These parameters of acceleration, speed or amplitude of the movement can thus differ between the various activation cycles. In this way the person performing the exercise is not only subjected to an external action of sudden imbalance, but also, optionally, of different intensity with respect to the previous action (s).

According to a preferred variant, the device further comprises one or more sensors connected to the control unit.

As a function of the information collected by the aforesaid sensors and sent to the control unit, this latter can adjust one of the aforesaid parameters (frequency, acceleration, speed or amplitude) and generate, dynamically, a given sequence of activations and deactivations of the actuator means and thus of movements of the mass.

According to a particular embodiment, said sensors can comprise sensors adapted to detect the position, the speed or the acceleration of the part to which they are applied. Sensors of this type are, for example, accelerometers or equivalent devices.

In a variant of the invention, said sensors can be applied directly to the body of the device in order to detect the position in space of the device, for example with respect to an absolute reference or with respect to a part of the body of the user using the device, its speed of movement, its acceleration or more than one of the aforesaid parameters.

According to another variant, alternatively or in combination with the one described above, said sensors can be applied to the body of a person, this latter being the person performing the exercise or another person in charge of controlling the device, for example a trainer. In this case, the sensors detect the aforesaid sizes referred to the part of the body of the person to which the sensor is applied.

As a function of these parameters detected, the control unit is capable of calculating the instants of activation and deactivation of the actuator means (frequency, time intervals, etc.), as well as, optionally, adjusting the intensity and the amplitude of the movements of the mass. Moreover, in any one of the variants described above, the device can comprise one or more sensors, connected to the control unit, adapted to detect the biometric parameters of a person.

According to this configuration, these sensors can be associated with the body of the user performing the exercise and can provided the external control unit with information regarding the physical conditions of said user.

For example, in the case in which a heart rate monitor is provided, the control unit can modify activation and deactivation of the actuator means based on the user's heart rate, for example limiting the frequency of activation if the user is fatigued.

According to another aspect of the invention, the control unit can be operatively associated with an external control unit, adapted to generate controls for activation and deactivation of the actuator means and optionally to adjust the movement parameters of the mass.

This external control unit can comprise, for example, a display unit and an input/output interface, for example in the form of portable device, such as a tablet, smartphone or the like.

Preferably, the device is provided with a wireless communication module to receive data from the various sensors or to receive commands from the external control unit and send the display unit all the information required for the user carrying out the exercise or for a trainer. Optionally, the aforesaid sensors can be connected to the control unit by wired connections.

According to a first variant of the invention, the control unit is integrated in the exercise device. The external control unit is thus used for reading and selecting training programs stored in the control unit. The external control unit can also be used to write and store personalized programs in the control unit. According to this variant, the control signals of the actuator means are therefore supplied to the control unit on the device. According to another variant, the control unit can be integrated in the external control unit. This latter, in this variant, is therefore part of the device. The sequence of activations and deactivations of the actuator means is therefore stored or generated in the external control unit and sent to the exercise device. This latter is provided with a communication interface adapted to receive the aforesaid control signals to activate and deactivate the actuator means, carrying out the sequence generated by the external control unit. The communication interface can be included in a local control unit adapted to manage the power signal for activation and deactivation of the actuator means.

According to another aspect of the invention, the mass used can be an eccentric mass or a balanced mass that rotates about at least a first axis X.

In the first case, the destabilizing effect is provided by the sudden variation of the centroid of the device, which affects the balance of the user that is gripping or wearing it.

In the second case, the destabilizing effect is generated by the gyroscopic effect, caused by the sudden rotation of the mass, which applies to the body of the device a moment that tends to take the device from a generic position toward a position of balance.

According to another aspect of the invention, the mass can be connected to the body so as to also rotate about a second axis of rotation Y, transverse or, more preferably, perpendicular to the first.

According to another aspect of the invention, said actuator means are selected from electric motors, linear actuators, pneumatic or hydraulic pistons, or electromagnets.

However, electrically powered actuators are preferable, as they allow the device to be supplied by means of a battery, preferably rechargeable, mounted on the device, increasing its versatility and practicality of use.

According to a variant of the invention, the body of the device can comprise a casing inside which at least the mass and optionally the actuator means are positioned. Said casing can be provided with one or more grips to be grasped by a user. Alternatively, or additionally, the casing can be provided with connection means, such as belts, bands or the like to be applied to a limb or to another part of the body of the user.

According to another variant of the invention, the body can comprise a sleeve that can be releasably applied to an element in the form of a rod or the like. In this variant, the mass is preferably connected to the body so as to rotate and translate with respect thereto.

This variant allows, for example, the exercise device of the invention to be applied to gripping means, such as barbells or the like, in place of the standard weight discs.

Further features and details of the invention will be better understood from the description below, provided by way of non-limiting example, and from the accompanying drawings, wherein:

Fig. 1 is a schematic view of the exercise device according to an embodiment of the present invention;

Fig. 2 is a schematic view of the exercise device according to a further embodiment of the present invention;

Fig. 3 is a schematic view of the exercise device according to another embodiment of the present invention.

With reference to Fig. 1, the numeral 1 indicates as a whole the exercise device according to the invention. The device comprises a body 10 provided with handles 1 1 or the like, which can be gripped by a user to carry out physical exercises during which said device is moved and/or rotated in space.

According to a preferred variant, the body 10 can be provided with other connection means 12, such as belts, bands or the like, to apply the device to the lower limbs or to another part of the body of the user.

In a first embodiment, the body 10 comprises a casing 13, preferably, but not necessarily, closed. Said casing 13 is preferably made of a rigid material, for example metal, or of a plastic material. The casing 13 can be produced with different shapes as a function of the exercises in which it is to be used. For example, this casing can be substantially spherical, as shown in the examples of Fig. 1 , tubular or discoid in shape. More in general, the casing 13 can have any shape that allows it to be easily moved by a user standing, seated or lying down.

The casing 13 is preferably composed of two or more parts, which can be separated and reattached to one another, so as to facilitate any inspection and maintenance operations on the device.

Housed inside the casing 13 is a support 14 to which a mass M is connected, with the possibility of rotating about a first axis of rotation X.

Said mass M can be eccentric with respect to at least the first axis of rotation X, such as in the example of Fig. 1, or balanced.

The support 14 can be fixed with respect to the casing 13 or, preferably, can be hinged to this latter so as to rotate about a second axis of rotation Y, substantially perpendicular to the first.

The rotation of the mass M with respect to the support 14, and of this latter with respect to the casing 13, is imparted respectively by a first motor 15 and by a second motor

16, preferably electric. For improved control of the position of the mass M, the aforesaid motors 15, 16 can be stepper motors or, alternatively, can be associated with an encoder device.

The power to the motors 15, 16 is supplied by a battery 17, preferably rechargeable, which can also be placed in the casing 13 or, as shown in the example in the figure, on the outside of this latter. A connector, not illustrated, can be arranged on the outer part of the casing for connection of a battery charging device.

According to a further variant, the device can comprise several masses M, also made to rotate about the same axis, and each connected to a motor controlled independently.

Activation and deactivation of the motors 15, 16 are managed by a control unit 20. According to the invention, at least one training program, according to which the control unit activates and deactivates the motors 15, 16 with a specific sequence, is stored in the control unit. The program can contain information concerning:

the acceleration, the speed or the amplitude of the rotations of the mass M about the axes X and Y;

the direction of rotation of the mass M about the axes X and Y;

the interval of time of activation of the motors 15, 16;

the interval of time of deactivation of the motors 15, 16, between one activation and the next;

the total duration of the sequence of activations and deactivations.

According to the invention, the control unit 20 includes a communication module 21 , preferably wireless, to exchange information and controls with an external control unit 30. This external control unit 30 can be used by the user or by a trainer to select and launch a given stored program.

The external control unit 30 can also be configured to create personalized programs and subsequently store them in the control unit 20 or simply send them to this latter.

For this purpose, the external control unit 30 can comprise, for example, a portable device, such as a tablet, smartphone or the like, provided with a touch screen 31 that acts as display unit and input/output interface.

According to a preferred variant, the device is equipped with one or more position sensors 18, for example accelerometers, gyroscopes, magnetometers or the like. Said sensors are in communication with the control unit 20, which, as a function of the signals received, determines the position in space of the device, or other parameters related to its movement. As a function of this position, the control unit can set, in real time, one or more of the aforesaid control parameters of the motors 15, 16 such as the activation frequency, the acceleration, the speed or the amplitude of the movement of the mass. Alternatively, again for the purpose of detecting the position in space of the device, the control unit 20 can be connected to other visual sensors, for example video cameras or the like, which film the movements of the device or of the person performing the exercise.

According to another variant of the invention, the device is equipped with one or more sensors 40, connected to the control unit 20, applicable to the body of the user performing the exercise.

In a first embodiment, said sensors 40 are position sensors, selected from those mentioned above, which , applied to one or more parts of the body of the user, are able to determine the position of said part(s) of the body or other parameters such as speed or acceleration.

According to another variant, optionally combinable with the variant described above, said sensors 40 comprise sensors of biometric type adapted to detect biometric parameters of the body of said user, for example a heart rate monitor. In this case, the control unit 20 can adjust the parameters of the sequence of activations and deactivations of the actuator means 15, 16 in real time as a function of the physical conditions of the user.

Fig. 2 illustrates an exercise device 100 according to another variant of the invention. The device comprises a body 110 in the form of a bar, rod or the like, provided with one or more grips 1 1 1. The body 1 10 is fitted with a guide 1 12 to which a mass M is connected in a sliding manner, with the possibility of moving in a substantially rectilinear direction X.

The movement of the mass M is generated by an actuator 1 13, for example a linear actuator, a magnetic actuator or a pneumatic piston. If the actuator 1 13 is electric, it is supplied by a battery 1 14. Activation and deactivation of the actuator 1 13 are controlled by a control unit 120 having the same features as the control unit 20 described for the previous variant. In this specific case, the aim of the control unit is to manage the parameters of the actuator 113 to control at least one of the following parameters:

the acceleration, the speed or the amplitude of the movement of the mass M along the direction X;

the direction of movement of the mass M along the direction X;

the interval of time of the activation of the actuator 1 13;

the interval of time of deactivation of the actuator 1 13, between one activation and the next;

the total duration of the sequence of activations and deactivations.

Similarly to the previous variant, the device can be provided with a position sensor 1 15, mounted thereon, connected to the control unit 120.

This latter can interface with the external control unit 30 described above and optionally with the further sensor 40 that can be associated with the body of the user, of position or biometric type.

Fig. 3 illustrates a further variant of the exercise device according to the present invention.

The device, indicated as a whole with 200, comprises a body 210 in the form of a sleeve or the like, configured to be associated with an element E in the form of a rod, barbell, bar or the like.

The sleeve 210 comprises a fixed portion 21 1 , connectable to the aforesaid element E, and a moving portion 212, which can slide with respect to the fixed portion along a direction X. The movement of the moving portion 212 is provided by a linear actuator 213 selected from those listed for the previous variant.

The moving portion 212 in turn acts as support for at least one mass M connected to said moving portion so as to rotate about the axis X. The mass M is mad to rotate by a motor 214 such as those described for the first variant of the invention.

A covering element 215 integral with the moving portion 212 can at least partially surround said mass M to prevent contact thereof with the body of the user or with other objects during rotation. The device, in this configuration, can advantageously be used in place of the standard weight discs applied to barbells or dumbbells. i.

A control unit 220 is connected to the actuator 213 and to the motor 214 to control the movements and the rotations of the mass M, according to the same operating logic already described for the previous variants.

For this purpose, the control unit 220 can be connected to a position sensor 216, mounted thereon, or 40, applicable to the body of the user, to the external control unit 30 or to the further sensor 40 of biometric type.

The power to the actuator 213, to the motor 214 and to the control unit 220 is supplied by a battery 217.

The invention has been described purely for illustrative and non-limiting purposes, according to some preferred embodiments. Therefore, a person skilled in the art can make modifications or variations, all of which are considered as falling within the scope of protection of the present invention.
