Description
- The present invention generally relates to the technical field of the machines for the power exercise, for sport as well as for medical purpose, and particularly relates to a machine for the power exercise of a user.
- The invention further relates to a modification kit and a method for obtaining such machine starting from a standard existing machine for power exercise.
- The invention further relates to a method and a software product for controlling the machine.
- The known machines for the power exercise of a user, for simply sport or for medical purpose, generally comprise a rocker movable by a user to make a work and a load connected to the rocker suitable to oppose the work of the user. The rocker is moved by the user along predetermined paths, defined by the machine.
- The load against which the user works is fix, and generally preset by the user before the exercise. This involves the need of a trainer who follows the exercise, so as to verify its correct execution and efficacy, and a high level of risks of physical damages, as distortions, muscular strains or the like, due to excessive loads.
- From the Japanese patent JP2185272 a machine for the rehabilitation of a user following a physical damage is known. This known machine has blocking means of the load in case the user exceeds a safety load threshold.
- From the international patent application WO2009107904 a machine for the power exercise of a user is known, which allows to set on a display several training programs, exclusively of isokinetic or isotonic type.
- From the European patent EP-B1-1252915 an apparatus for the power exercise of a user is known, comprising a device to increase or decrease the load even during the exercise. In particular, the user is provided with a control panel having a series of controls, to be voluntarily operated by the hands or the foots, to increase or decrease the weight to lift.
- This known machine is to be used by trained users or in any case with a trainer, because the variation of the lifted weight is subordinate to the user's will. For the same reason, this known machine does not eliminate the ranger of physical damages for the user.
- A main object of the present invention is to overcome, at least in part, the above drawbacks, by providing a machine for the power exercise of a user simple to manufacture and relatively cheap.
- Another object of the invention is to provide a machine for the power exercise of a user which can be used by everybody, even without the help of a trainer.
- Another object of the invention is to provide a machine for the power exercise of a user which minimizes or totally eliminates the dangers of physical damages for its users.
- These and other objects, as better explained hereafter, are fulfilled by the machine for the power exercise of a user having one or more of the features herein disclosed and/or claimed.
- Essentially, the machine may comprise a rocker movable by a user to make a work and a load connected to the rocker to oppose the work of the user. In other words, the user, acting on the rocker, makes a work against the load in a given time.
- As used herein, the expression “rocker” or derivates thereof is intended to indicate an element, or an assembly of elements connected to one another, with which a user interacts directly or indirectly to make a muscular work.
- As used herein, the expression “load” or derivates thereof is intended to indicate an element, or an assembly of elements connected to one another, suitable to generate the force against which the user makes the work.
- As used herein, the expression “work of a user” or derivates thereof is intended to indicate the work made by the user in the time unit against the load to move the rocker. In other words, the work of the user defines the power by which the user opposes the load.
- The rocker and/or the load may be installed on a load bearing support structure, or not.
- The machine may be designed to monitor the work of the user and to automatically adjust the resistant load according to the detected work.
- In particular, the machine according to the invention is suitable to automatically increase the load in response to the detection of the increase of the work and vice versa.
- With this aim, the machine comprise means to detect at predetermined time Intervals, which may have any size, at least one first value of at least one parameter corresponding to the muscular work made by the user against the load.
- The detected parameter may be, for example, the speed, or the acceleration of the execution of the exercise, or the force with which the user carries it out.
- On the other hand, the work of the user may be monitored by controlling his physical parameters, for example his heart-beat or the frequency of muscular contraction/decontraction.
- Of course, the detecting means may change according to the parameter to detect.
- Possibly, a plurality of parameters may be detected, simultaneously or not, for example force and speed.
- The machine may further include at least on logical control unit settable with at least one second value of at least one parameter corresponding to a training reference work for the user.
- Similarly to what above mentioned, the parameter to set may be, for example, the “ideal” performance speed or acceleration of the exercise, or the “ideal” force by which the user has to perform the exercise to train at best.
- These values, which change from one user to another, may for example be determined in a per se known manner from the so-called “force-speed curve”, which indicates for each user the muscular performances in terms of force and speed of execution of the exercises in a given moment.
- On the other hand, also the “ideal” heart-beat may be set, which can be obtained by means of an electrocardiogram.
- Furthermore it is possible to set also the frequency of muscular contraction/decontraction, which can be determined by means of an electromyography.
- The setting may be made manually, for example by means of a touch-screen type display, or automatically.
- The automatic setting may be made by means of a software program which reads from a memory unit, which may be integrated in the machine, one or more values of one or more parameters of the user, possibly preloaded into the memory unit by having the same user worked in standard conditions, and so sets the first logical unit, according to a predetermined algorithm.
- For example, the machine may be programmed in such a way that, before the exercise or anyway with predetermined periodic rate, it determines the values of interest, for example those of the force-speed curve, or the heartbeat, or the muscular contraction/decontraction frequency, by having the user worked in predetermined standard conditions suitable to detect such parameters.
- These data may be then loaded into the memory of the machine, and may be used by a software program which analyses and employs them to determine the “ideal” reference value or values to which the user has to strive during the exercise. The determination of these values may take place by means of one or more predetermined algorithms, incidentally selectable by the user on the basis of his needs.
- For example, it may be possible to select a program for the development of the muscular mass, rather than another program for the development of the explosive force.
- This way, the machine is completely automatic as well as extremely safe for the user.
- Appropriately, the first logical control unit may be operatively connected with the detecting means to compare the work detected by these last ones with the reference work.
- Of course not necessarily the first detected value has to be coherent with the second set value. If, for example, the detecting means are configured to detect the force with which the user makes the exercise, for example by means of a load cell, it is possible to set a second value of ideal speed of performance. In this case, the first logical control unit provides to translate, by means of the values of the above mentioned force-speed curve, the set “ideal” speed value in an “ideal” force value, so as co compare with one another coherent quantities.
- Preferably, the machine may comprise regulating means, which may be operatively connected to the first logical control unit, acting on the load for automatically increase it in case the work detected by the detecting means is greater than the set reference work, and to automatically decrease it in case the detected work is lower than the set reference work.
- Thanks to such features, the machine may be used in complete safety by anyone, even without the help of a trainer. Every instant, in fact, the muscular work of the user tends towards the “ideal” training muscular work.
- For the user it is sufficient to set the correct “ideal” work, which may be previously determined as above mentioned, and to start to train. In the case of the automatic setting, the user has simply to follow the instruction of the machine, because the machine itself sets for him the “ideal” parameter towards which he has to tend during the exercise.
- Differently from the traditional isotonic or isokinetic machines, in fact, the machine according to the present invention adapts itself to the work of the user every instant.
- This particular “adaptive” configuration of the machine, moreover, minimizes or completely eliminates the dangers of physical damages for whom uses it, and allows an extremely efficient training.
- Appropriately, the “ideal” work values may be two, so as to define an “ideal interval” within which the user can train. In this case, the machine automatically “adapts” the load in case the user works outside the ideal work interval, that is below the minimum work or above the maximum work.
- Advantageously, the machine may comprise a unit for the electro-magnetic stimulation of human muscles, which includes at least one inductor positionable close to at least one muscle of the user, at least one power supply connected to the inductor for the generation of at least one electromagnetic field and a generator of pulse current for the emission of current impulses having predetermined frequency and duration towards the inductor to cause the involuntary contraction and decontraction of the human muscle in proximity of which the inductor is put.
- Preferably, the first logical control unit may be operatively connected to the electromagnetic stimulation unit to automatically disconnecting the power supply in case the work detected by the detecting means coincides with a value of at least one parameter corresponding to a dangerous set work.
- In this case, the machine may be lacking in the above described regulating means, or not.
- Preferred but non-exclusive embodiments of the invention are defined by the dependent claims.
- Further features and advantages of the invention will appear more evident upon reading the detailed description of some preferred, non-exclusive embodiments of a machine according to the invention, which are described as non-limiting examples with the help of the annexed drawings, in which:

FIGS. 4 and 5 are similar to those inFIGS. 1 and 2 , and differ from them in the manner in which themachine 1 continuously adapts the load to the work of the user. - The fifth embodiment illustrated in
FIG. 7 is suitable to train the muscles of the user's legs, and is conceptually similar to a classical “gym bike” which continuously adapts the load to the user's work. - The sixth embodiment illustrated in
FIG. 8 is suitable to train the muscles of the upper part of the user's body, in particular the pectoral muscles, and differs from the embodiment ofFIG. 1 because it includes a unit for the electromagnetic stimulation ofhuman muscles 90. - The seventh embodiment illustrated in
FIG. 9 is suitable to train the muscles of the upper part of the user's body, in particular the pectoral muscles, and differs from the embodiment ofFIG. 1 because it lacks in the regulating means 60. - Where not differently specified, features common to all embodiments of the machine are indicated with the same number.
- The
machine 1 may comprise a support structure, in particular aload bearing frame 10 with a base 11 to be laid on the floor G, on which are mounted arocker 20, movable by a user to make a work, connected to aload 30, suitable to oppose to the work of the user. - In the illustrated embodiments, the movement of the
rocker 20 is guided. In particular, the latter may comprise aslider 21 slidably mounted along aslide bar 22, which defines the axis X along which the movement of the rocker takes place, in the two senses indicated by the arrows F1 and F2. On the other side, therocker 20 may also be free, provided that it is connected to theload 30, without departing from the scope of the invention defined by the appended claims. - In particular, the bearing
frame 10 of the first, third, sixth and seventh embodiment of the machine, illustrated inFIGS. 1 , 4, 8 and 9, may include abench 12, which may be plane or inclined, on theupper surface 13 of which the user may lie down to grasp and move theslider 21 upward or downward. For this purpose, therocker 20 may comprise a substantiallyhorizontal barbell 23, graspable by the user to make the exercise, rigidly connected to theslider 21. - On the other hand, the
rocker 20 of the second and fourth embodiment of the machine, illustrated inFIGS. 2 and 5 , may comprise aseat 24, on which the user may sit to move theslider 21 along thebar 22. With this aim, the bearingframe 10 may comprise afootrest plate 14, against which the user sitting on theseat 24 may push his feet to train. - Moreover, the
rocker 20 of the fifth embodiment of the machine, illustrated inFIG. 7 , may comprise a group of pedals-pedalcrank 25, which the user may set into rotatory motion around the axis Y. With this aim, the bearing frame may include a gym bike, not illustrated in figure because per se known, on which the user may sit to train. - The
machine 1 is so configured as to automatically adapt itself to the user's work, to almost totally eliminate any risk of physical damages during the exercise. - For this purpose, control means may be provided, which may include detecting
means 50 suitable to monitor the work of the user at predetermined time intervals, by detecting one or more parameters directly or indirectly connected to the same work, and alogical control unit 51 suitable to compare the detected value with one or more “ideal” reference training values manually set by the user, for example by means of a display, or automatically set by a software. - Regulating means 60 may be operatively connected to this
logical control unit 51, which act on theload 30 fir the automatic regulation thereof in response to the detection of a variation of the detected value from the preset or predetermined value or values. - Advantageously, the regulating means 60 may be designed to automatically increase the
load 30 in case the work detected by the detectingmeans 50 is greater than the “ideal” reference work set on thelogical control unit 51 and to automatically decrease theload 30 in case the detected work is lower than the set reference work. - This way, the machine continuously urges the muscular work of the user towards the training muscular work, adapting itself to the user's work instant by instant.
- The machine furthermore minimizes the risks of physical damages for the user, because if the work detected by the detecting
means 50 is lower than the reference one, the machine automatically decreases the load. - Appropriately, the
machine 1 may comprise motor means, generally indicated with 31, suitable to generate a torque which defines theload 30. - In the first, second, fifth, sixth and seventh embodiment of the machine, illustrated in
FIGS. 1 , 2, 7, 8 and 9, the user, acting on therocker 20, works directly against the torque generated by the motor means 31. - The latter may comprise a brushless motor of the step type, so as to generate a torque also when not in motion without any danger of damages or breakings.
- In order to rigidly and integrally transfer the motion between the
rocker 20 and the motor means 31, motion transmission means of the closed ring type may be provided. - The latter may comprise a ring shaped
motion transmission 40, for example a rope, a belt, a band or a chain or the like, connected to themotor 31 by means of a toothed-wheel 42 keyed on theaxis 32 thereof and to therocker 20 by means of connectingmeans 41, for example a couple of clamps welded to theslider 21. One or more returningidle pulley 43 may be provided, too. - In the first, second, fifth, sixth and seventh embodiment of the machine, illustrated in
FIGS. 1 , 2, 7, 8 and 9, the parameter monitored by the control means for controlling the work of the user may be the speed and/or the acceleration imparted on therocker 20 as a result of the user's work. - With this aim, the detecting
means 50 may be operatively connected to therocker 20 to control the movement thereof determined by the user's work against theload 30, that is against the torque generated by themotor 31. - For this purpose, such detecting means may comprise an
encoder 50′, or an accelerometer, keyed on theaxis 32 of themotor 31 to detect the speed Vb, or the acceleration, of therocker 20 in response to the work of the user. - While the present description, for simplicity reasons, is always referred to the
encoder 50′ and to the monitoring of the speed of therocker 20, it shall be understood that the same is valid also for the control of the acceleration thereof by means of the accelerometer. - Advantageously, as visible in
FIG. 3 , the control means may also include a firstlogical control unit 51, operatively connected to theencoder 50′, manually or automatically settable with at least one reference speed value Vr and susceptible to compare at predetermined time intervals the speed value Vb detected by theencoder 50′ with the reference value V, to generate afirst error signal 52 in case the two values do not coincide. - The embodiments illustrated in
FIGS. 1 , 2, 3, 7 and 8 refer to a control made by twological units logical units single software program 100 suitable to interact with both theseunits software subroutine 101 and the second logical unit may interact with thesoftware subroutine 102. Equivalently, eachlogical unit - It shall however be understood that in these embodiments the control of the machine may take place also by means of a single
logical unit 51, as happens in the embodiments illustrated in theFIGS. 4 , 5 and 6, without departing from the scope of the invention expressed by the annexed claims. - The first
logical unit 51 may be furthermore susceptible to incorporate in the first error signal 52 afirst information 53 concerning the deviation VΔ between the detected speed Vb and the reference speed Vr, in other words whether and how much the speed imparted by the user to therocker 20 is higher or lower than the ideal one. - The regulating means may comprise a second microprocessor
logical unit 60 operatively connected to thefirst unit 51 and to themotor 31, actionable by thefirst error signal 52 and susceptible to elaborate the first piece ofinformation 53 to generate asecond error signal 61, to be transmitted to themotor 31. - The
second error signal 61 may incorporate asecond information 62 concerning the deviation torque CΔ, calculated by the secondlogical unit 60 on the basis of the deviation speed VΔ, to be added to or to be subtracted from the speed presently delivered by themotor 31. In other words, thesecond error signal 61 indicated whether and how much power has to be delivered or subtracted to themotor 31 to increase or decrease theload 30. - In a preferred but non-exclusive embodiment, the first and the second
logical units control unit PLC 70. On the other hand, the firstlogical unit 51 and the regulating means 60 may belong to a single control card. - This way, every instant, the machine adapts the
load 30 to the work made by the user, in such a manner to increase it if the user makes a work greater than the ideal one and to decrease it if the user is making a work lower than the ideal one. - To do this, in the moment when the performance speed of the exercise Vb deviates from the ideal reference speed Vr, the machine automatically acts on the
load 30, so as to subtract power from themotor 31 if VΔ=Vb−Vr is negative, because the user is getting tired and so the load is decreased to allow him a correct exercise, and to add power to themotor 31 if VΔ is positive, because the user is working above the ideal work and so the load is increased to allow a correct exercise. - Consequently the performance speed of the exercise by the user varies every instant on the basis of the regulating of the load made by the machine.
- This way, the risks of uncontrolled and dangerous works due to incorrect behaviours of the user are minimized, if not completely eliminated. In particular, the dangers of muscular damages at the end of the exercises, when the user is more tired because of the initially made work, are minimized.
- The speed values to set are individual parameters of the user, and vary depending from the training. For example, they may be fixed on the basis of an equivalence given by the “speed-force” curve after having let the user to work on the basis of a standard curve, according to techniques known by person skilled in that art.
- As already said before, this set may be defined manually, for example by means of a touch-screen display, or automatically, as above mentioned.
- In particular, the value Vr may be determined so as to correspond to the ideal work value for the development of the muscular mass and/or of the explosive force of the user. After determining this value, the PLC has to be set with such reference value Vr, so that the system adjusts the load every time the user deviates from this value.
- Appropriately, it is possible to set the
PLC unit 70 with a plurality of reference values, for example two, so to be able to choose every time the exercise type which is most suitable to one's needs. - In particular, on the
PLC 70 may be set two reference speed values, a first value corresponding to the ideal work value Vr,min for the development of the muscular mass and a second value corresponding to the ideal work value for the development of the explosive force Vr,max of the user. The machine will adjust at every time the load so as to let the user work around one of these two values. - On the other side, it is possible to program the
PLC 70 so as to induce the user to work in the speed Interval between these two values Vr,max, Vr,min, or anyway in an interval between two ideal speed values so calculated that the exercise is effective for the user, decreasing theload 30 if the performance speed of the exercise detected by theencoder 50′ is lower than the lower reference value Vr,min between the two and increasing it if the detected speed Vb is higher than the higher reference value Vr,max. - In fact, in this last case, the user makes a work greater than the maximum work to be made by the user so that the exercise is effective, whereas in the first case the user makes a lower work than the minimum ideal work. Also in this case, therefore, the machine adjusts the load to induce the user to work within the work interval which is ideal for the efficacy of the exercise, avoiding at the same time any muscular damages.
- Advantageously, it is also possible to set the first
logical unit 51 with at least one dangerous speed value Vs, corresponding to a limit value of work that the user can made in safe conditions. Also this value may be determined according to techniques known by the person skilled in that art. Advantageously, means 80 may be provided to block therocker 20, operatively connected with thelogical unit 51, if the speed value Vb detected by theencoder 50′ is equal to the value Vs. - Even if in the embodiments illustrated in the
FIGS. 1 , 2, 3, 7 and 8 the control on the danger speed Vs is made by the firstlogical unit 51, which controls the reference speed Vr too, this control may be made also by a third logical unit, connected with the blocking means 80 and subsequent to thefirst unit 51, or by asoftware program 100, as shown for the embodiments of theFIGS. 4 , 5 and 6, without departing from the scope of the invention defined by the appended claims. - The blocking means 80, in response to the detection by the
encoder 50′ of a speed value Vb equal to the value Vs, may act on the motor means 31 to brake them, incidentally in a progressive way to avoid damages to the user. For this purpose, the blocking means 80 may comprise abraking unit 81 susceptible to elaborate theerror signal 82 coming from the firstlogical unit 51, generated in response to the detection of a speed value Vb equal to the value Vs, and transmits asignal 83 of a possible progressive brake to the motor means 31. - On the other hand, the blocking means 80 may comprise alarm means 84 susceptible to elaborate the
signal 82 coming from the firstlogical unit 51 and transmits asignal 85 for activating analarm 86, for example of acoustic and/or visual type, so to warn the user of the danger. - Further, the blocking means 80 may include restoration means to bring the
rocker 20 back to its rest position. With this aim, such restoration means may comprise aunit 87 susceptible to elaborate asignal 88 coming from thebraking unit 81 and transmit to the motor means 31 asignal 89 to drive the automatic placing of therocker 20. - The
signal 88 is transmitted by thebraking unit 81 after a time t, for example 1-2 seconds, from the transmission of thebraking signal 83 to the motor means 31. - In order to have the
machine 1 memorize the pause position of therocker 20, it is possible to perform, before the exercise, a movement followed by a voluntary pause of the user, at first with the compressed muscle and then with the elongated muscle. The rest position may therefore correspond to the position of the elongated muscle, and may be voluntarily or automatically memorized in thePLC 70. - This movement of the user corresponds to the maximum stroke of the
slider 21, and is variable from one user to another one. A couple of mechanical locks may be also provided, which are repositionable along thebar 22 in correspondence with the beginning and the end stroke of theslider 21. - The
signal 89 then commands themotor 31 the reposition of therocker 20 in the rest position preset on thePLC 70. - In a first preferred but non-exclusive embodiment, the danger speed value Vs settable on the
PLC 70 may be the minimum danger speed value Vs,min corresponding to the minimum work to be safely made by the user, below which physical damages may occur to the user. On the other hand, it is possible, alternatively or together with the value Vs,min, to set thePLC 70 with a maximum danger speed value Vs,max, corresponding to the maximum work to be safely made by the user. - Appropriately, the first
logical unit 51 may carry out a double control on the speed Vb detected by theencoder 50′, a first control to verify whether the speed Vb is equal to the value Vs,min, or Vs,max, and incidentally to command to the blocking means 80 the blocking of therocker 20 in the positive case and a second control to verify the deviation from the reference value Vb, and incidentally to command to the regulating means 60 the adjustment of theload 30. - On the other hand, the
PLC 70 may carry out two safety controls, the first one to verify whether the performance speed of the exercise is equal to Vs,min, and the second one to verify whether it is equal to Vs,max, blocking therocker 20 by means of themeans 80 in the positive case. - The choice between the instantaneous or progressive stop commanded by the
signal 83 to themotor 31 depends from different factors, and may be preset in theunit 81. In a first preferred but non-exclusive embodiment, it is possible to set the instantaneous or progressive braking independently from the detected value Vb. - On the other hand, it is possible to set the braking according to whether the detected value Vb is equal to Vs,min or to Vs,max.
- In fact, if Vb is equal to Vs,min, it is possible to immediately brake the motor, because the performance speed of the exercise by the user is per se low, and an instantaneous braking cannot cause him any damages.
- If, on the contrary, Vb is equal to Vs,max, it is possible to carry out a progressive braking, because performance speed of the exercise by the user is per se high, and an instantaneous braking may cause him some damages.
- In order to progressively brake the
motor 31 thesignal 83 may command a braking ramp having more or less slope to themotor 31 itself, according to techniques known to the person skilled in that art. - Appropriately, the speed may be progressively reduced, for example at first one tenth, then one fifth of the preceding value and so on, until it corresponds to the value Vs,min, after which the
unit 81, after the time t has passed, transmits thesignal 88 to theunit 87 to bring therocker 20 back to the rest position, at the same speed Vs,min. - In the third and fourth embodiment of the
machine 1, illustrated in theFIGS. 4 and 5 , the user, acting on therocker 20, does not directly work against the torque generated by the motor means 31. - With this aim, for the transmission of the motion between the
motor 31 and therocker 20 anendless screw 45 may be provided, which is keyed on theaxis 32 of themotor 31. Theendless screw 45 is operatively connected to apinion 46, which is rigidly connected to therocker 20 by means of themetal bar 47. - This way, the user works against the friction generated between the
pinion 46 and theendless screw 45, that is against a mechanical force. - In this case, the parameter monitored by the control means for controlling the work of the user may be the force the user exerts against the
rocker 20. - For this purpose, the detecting means may comprise a
load cell 50″, which may be connected to therocker 20, or not. In fact, in the embodiment ofFIG. 4 theload cell 50″ is connected to therocker 20, whereas in the embodiment ofFIG. 5 theload cell 50″ is not connected to therocker 20. - As illustrated in
FIG. 6 , differently from the first and second embodiment illustrated inFIGS. 1 and 2 , the regulation of theload 30 is carried out on the basis of force values and not of speed or acceleration values. - The control, then, is carried out by means of a single
logical unit 51 which interacts with thesoftware program 100. - Apart from these differences, the running of these embodiments is equivalent to those illustrated in
FIGS. 1 and 2 . - Advantageously, therefore, the first
logical control unit 51, operatively connected to theload cell 50″, may be automatically or manually settable with at least one reference force value Fr and susceptible to compare at predetermined time intervals the force value Fb detected by theload cell 50″ with the reference value Fr to activate the regulating means 60, defined by asubroutine 102 of thecomputer program 100, in case the two values do not coincide. - The
subroutine 102 calculates the deviation FΔ between the detected force Fb and the reference force Fr, in other words, whether and how much the force exerted by the user on therocker 20 is greater or lower than the ideal one. - The
subroutine 102 further calculates the deviation torque CΔ, incorporating it in asecond error signal 61 destined to themotor 31. - In the moment when the performance force of the exercise Fb deviates from the ideal reference force Fr, the
software 100 automatically acts on theload 30, so as to provide to subtract power from themotor 31 if FΔ=Fb−Fr is negative, as the user is getting tired and therefore the load is decreased to allow him a correct exercise, and to add power to themotor 31 if FΔ is positive, because the user is working above the ideal work and therefore the load is increased to allow him a correct exercise. - Also in the third and fourth embodiment of the
machine 1, illustrated in theFIGS. 4 and 5 , it is possible to set thePLC unit 70 with a plurality of reference values, for example maximum and minimum reference force Fr,max, Fr,min, and to set the machine so that the user works within that interval. - It is also possible to set the first
logical unit 51 with at least one danger force value Fs, and to set the blocking means 80 to block, incidentally in a progressive way, therocker 20, operatively connected to thelogical unit 51, if the force value Fb detected by theload cell 50″ is equal to the value Fs. - Even if in the first and second embodiment illustrated in the
FIGS. 1 and 2 the regulation of theload 30 is carried out by means of the twological control units FIGS. 4 and 5 the regulation is carried out by means of a singlelogical unit 51, it is understood that for all the embodiments of themachine 1 the regulation of theload 30 may be carried out in any manner without departing from the scope of the invention as defined in the appended claims. - In particular, in the embodiments illustrated in the
FIGS. 1 and 2 it may be possible to adjust theload 30 by means of thesoftware program 100 which interacts with asingle control unit 51, or in the embodiments shown in theFIGS. 4 and 5 it may be possible to adjust theload 30 by means of thesoftware program 100 which interacts with the twological control units - The running of the fifth embodiment of the
machine 1 illustrated inFIG. 7 is similar to the running of the first and second embodiment, illustrated inFIGS. 1 and 2 . Also in this case, in fact, the machine adjusts the load on the basis of the speed values detected by theencoder 50 keyed on the axis of themotor 31, against which the user directly works. - The only difference is that, in this case, the
rocker 20 is put into rotatory motion around the axis Y, and not in sliding motion along the axis X. The running of the detectingmeans 50, of the firstlogical unit 51 and of the regulating means 60 is identical, as visible inFIG. 7 . - Appropriately, the
machine 1 may include a unit for the electromagnetic stimulation of thehuman muscles 90. - In
FIG. 8 is illustrated, as a non-limiting example, an embodiment of themachine 1 similar to the embodiment illustrated inFIG. 1 , which includes theunit 90. It is however understood that theunit 90 may be coupled to any configuration of themachine 1, and in particular to those according to theFIGS. from 2 to 7 , without departing from the scope of the invention expressed by the annexed claims. - In an alternative embodiment, illustrated in
FIG. 9 , the machine which includes theunit 90 may not comprise the regulating means 60. In other words, the machine which includes theunit 90 may be not configured to adjust the user's work to the ideal work. In this case, the reference work to set, automatically or manually, on thelogical unit 51 is the dangerous work. - The
unit 90 may comprise at least oneinductor 91, positionable in proximity of at least one muscle of the user, at least onepower supply 92, connected to the inductor for the generation of at least one electromagnetic field and a generator of pulse current 93 for the emission of current impulses having predetermined frequency and duration to theinductor 91 to cause the involuntary contraction and decontraction of the human muscle in proximity of which is put theinductor 91. - For example, the
unit 90 may be arranged according to the teachings of the U.S. Pat. No. 6,652,443 and/or of the International application WO0225675, to which it is referred for consultation. - This way, it is possible to have the user train with the maximum efficiency.
- By means of an electromyography, in fact, it is possible to know the current frequency and intensity suitable to contract and decontract one or more muscles of interest. Placing the
inductor 91 close to the muscle or to the group of muscles of interest, it will be therefore possible to induct contraction and decontraction even beyond the user's will, making the training particularly efficient. - In order to avoid damages to the user, the first
logical control unit 51 is operatively connected to theelectromagnetic stimulation unit 90 for automatically disconnecting thepower supply 92 if the work detected by the detectingmeans 50 coincides with the dangerous set work, whether it is Vs or Fs. - It is also possible to set the
unit 90 so that to have the generator of pulse current 93 generates current impulses having different frequency and durations according to whether the user is lifting therocker 20, or whether he is letting it down. - According to a further aspect of the invention, a method for the control of the
load 30 in themachine 1 is provided, which may be carried out by a software product, in particular by asoftware program 100. - The software product may include one or more memory supports, which may be fix, for example one or more hard disk, or removable, for example one or more floppy disks, CD or DVD, on which the
program 100 is fixed. These memory supports may interact with thelogical control unit 51 to control theload 30. - The software product may further comprise one or more integrated circuits belonging to the
logical control unit 51. - In the case of a machine with two
logical units software program 100 may interact with both these units, or eachunit - The
program 100 may include afirst subroutine 101 susceptible to interact with the detecting means 50 to read the first value Vb or Fb detected by the detectingmeans 50 and to compare this first value Vb or Fb with the second reference value Vr or Fr. - The
program 100 may further comprise a secondoperative subroutine 102, actionable by the firstoperative subroutine 101 if the compared values do not coincide. The second operative subroutine may be designed to generate thefirst information 53, concerning the deviation VΔ or FΔ between the first value Vb or Fb and the second value Vr or Fr. - The second
operative subroutine 102 may further elaborate thefirst information 53 and generate thesecond information 62 concerning the deviation CΔ to be added to or to be subtracted from theload 30. - In particular, the
second information 62 may comprise a positive deviation CΔ if thefirst information 53 includes a positive deviation VΔ or FΔ, that is if the detected work is greater than the reference one, and a negative deviation CΔ if the first piece ofinformation 53 includes a negative deviation VΔ or FΔ, that is if the first piece ofinformation 53 includes a negative deviation, that is if the detected work is lower than the reference one. - The second
operative subroutine 102 may furthermore elaborate thesecond information 62 to cause the increase of theload 30 if thesecond information 62 includes a positive deviation CΔ and to cause the decrease thereof if thesecond information 62 includes a negative deviation CΔ. - In the case of a machine with a single
logical unit 51 the secondoperative subroutine 102 practically defines the regulation means 60. In other words, the regulation means 60 may be constituted by thesubroutine 102. - It is understood that, in the case of a control made with the two
logical units FIGS. 1 , 2, 3, 7 and 8, thefirst subroutine 101 may interact with thelogical unit 51, or it may be implemented therein, whereas thesecond subroutine 102 may interact with the secondlogical unit 60, or it may be implemented therein. - Advantageously, the
software program 100 may further include athird subroutine 103 susceptible to compare the first value Vb or Fb detected by the detecting means 50 with the third value Vs or Fs corresponding to the dangerous work for the user. - The third
operative subroutine 103 may furthermore interact with the blocking means 80 to activate them if the two compared values do not coincide. - According to another aspect of the invention, a kit is provided, for obtaining the
machine 1 through the modification of an existing standard machine for the power exercise which includes a rocker, a load, usually including a series of plates of predetermined weight, and a motion transmission element, usually of the rope or belt type, having a first end connected to the rocker and the other end connected to the load. - The kit may include the
motor 31, which may substitute the existing load, means for the rigid connection of the existing rocker to themotor 31, for the substitution of the existing transmission element, the detectingmeans 50, the firstlogical control unit 51 and the regulation means 60. - The modification of the existing machine may further provide the connection thereto of the detecting
means 50, of the firstlogical control unit 51 and of the regulating means 60. - Advantageously, in a preferred but non-exclusive embodiment, the first
logical unit 51 and, if present, the secondlogical unit 60 may belong to a singlecontrol unit PLC 70. - The kit may advantageously comprise the
computer program 100. - By means of the above described kit it is possible to simply and quickly modify one or more existing standard machines for the power exercise, for example the standard machines present in a gymnasium or in a fitness center.
