TITOLO TITLE
MACCHINA PER ESERCIZI FISICI PER LA CONTRAZIONE DEI MUSCOLI DEL CORPO IN CONCENTRICA ED ECCENTRICA MACHINE FOR PHYSICAL EXERCISES FOR CONTRACTION OF BODY MUSCLES IN CONCENTRIC AND ECCENTRIC
D ESC RIZIO N E DESCRIPTION
Forma oggetto del presente trovato una macchina per esercizi fisici per la contrazione dei muscoli del corpo in concentrica ed eccentrica. The present invention relates to a physical exercise machine for concentric and eccentric contraction of the muscles of the body.
Per capire cosa significa contrazione eccentrica occorre fare un esempio: supponiamo di riuscire a muovere con le gambe un certo numero di pesi e sollevarli da una posizione iniziale ad una posizione finale di fine corsa (concentrica). Se nella posizione di massima estensione dell'articolazione (gamba) si aggiunge peso a quello già sollevato, ad un certo punto vediamo che l'articolazione si sblocca e cede sotto lo sforzo del carico per tornare alla posizione iniziale. To understand what eccentric contraction means, we need to give an example: suppose we are able to move a certain number of weights with our legs and lift them from an initial position to a final end position (concentric). If in the position of maximum extension of the joint (leg) weight is added to the one already raised, at a certain point we see that the joint is released and yields under the strain of the load to return to the initial position.
Quando il muscolo è in piena contrazione per poter invertire il movimento si è dovuto aggiungere una certa quantità di pesi che può, in alcuni casi, variare dalle due alle tre volte la quantità iniziale. When the muscle is in full contraction, in order to reverse the movement, a certain amount of weights had to be added which can, in some cases, vary from two to three times the initial amount.
Quando il muscolo si contrae per sollevare un peso questo lavora in concentrica; se lo stesso muscolo può sforzarsi per rimanere contratto viene costretto a distendersi per sovraccarico di forza, in questo caso lavora in eccentrica. When the muscle contracts to lift a weight it works concentric; if the same muscle can force itself to remain contracted, it is forced to stretch out due to an overload of force, in this case it works in eccentricity.
Attualmente l'unico modo per eseguire una contrazione eccentrica è quello manuale eseguita da un tecnico specializzato dotato di notevole esperienza Currently the only way to perform an eccentric contraction is the manual one performed by a specialized technician with considerable experience
Scopo del presente trovato è quello di sostituire la manualità nella fase eccentrica. The purpose of the present invention is to replace manual skills in the eccentric phase.
Ulteriore scopo è quello di poter utilizzare una tradizionale macchina concentrica aggiungendo alla forza dei pesi una forza controllata A further purpose is to be able to use a traditional concentric machine by adding a controlled force to the strength of the weights
I vantaggi che si ottengono dal presente trovato sono elencati al termine della descrizione The advantages obtained from the present invention are listed at the end of the description
Detti scopi e vantaggi sono tutti raggiunti dalla macchina per esercizi fisici per la contrazioni di muscoli del corpo in concentrica ed eccentrica, oggetto del presente trovato, che si caratterizza per quanto previsto nelle sotto riportate rivendicazioni. Said objects and advantages are all achieved by the machine for physical exercises for the contractions of muscles of the body in concentric and eccentric form, object of the present invention, which is characterized by what is foreseen in the following claims.
Questa ed altre caratteristiche risulteranno maggiormente evidenziate dalla descrizione seguente di due forme di realizzazione illustrate, a puro titolo esemplificativo e non limitativo, nelle unite tavole di disegno in cui: This and other characteristics will be more clearly highlighted by the following description of two embodiments illustrated, purely by way of non-limiting example, in the accompanying drawing tables in which:
- la figura 1 illustra in forma schematica la macchina secondo una prima forma di realizzazione con paziente nella posizione di inizio fase concentrica; Figure 1 schematically illustrates the machine according to a first embodiment with the patient in the starting position of the concentric phase;
- la figura 2 illustra in forma schematica la macchina in una seconda forma di realizzazione con paziente nella posizione di inizio fase concentrica; Figure 2 schematically illustrates the machine in a second embodiment with the patient in the starting position of the concentric phase;
- le figure 3 e 4 illustrano le due macchine con paziente nella fase concentrica con sollevamento pesi; - figures 3 and 4 illustrate the two machines with the patient in the concentric phase with weight lifting;
- le figure 5 e 6 illustrano le macchine con paziente nella fase di fine concentrica e inizio fase eccentrica; - Figures 5 and 6 illustrate the machines with the patient in the end concentric phase and the beginning of the eccentric phase;
- le figure 7 e 8 illustrano le macchine con il paziente durante la fase eccentrica; - figures 7 and 8 illustrate the machines with the patient during the eccentric phase;
- le figure 9 e 10 illustrano le macchine a completamento della fase eccentrica - Figures 9 and 10 illustrate the machines completing the eccentric phase
Con particolare riferimento alla figura 1 , la macchina indicata nel suo complesso con 1 prevede un sedile 2 su cui si adagia una persona 3. With particular reference to Figure 1, the machine indicated as a whole with 1 provides a seat 2 on which a person 3 rests.
Al sedile 2 è incernierato un braccio oscillante 4 che porta all'estremità libera un rullo 5. An oscillating arm 4 is hinged to the seat 2 which carries a roller 5 at the free end.
Al braccio oscillante 4 è pure solidale un settore circolare di guida 6 per una fune o catena 7 che si avvolge su pulegge o rocchetti 8 per poi collegarsi ad una pluralità di pesi 9 che possono essere aggiunti o tolti in funzione dello sforzo che si vuole raggiungere con l'esercizio fisico. Also integral with the oscillating arm 4 is a circular guide sector 6 for a rope or chain 7 which winds on pulleys or spools 8 and then is connected to a plurality of weights 9 which can be added or removed according to the effort to be reached. with physical exercise.
Con 10 è stato schematizzato un fine corsa che delimita la corsa in discesa dei pesi 9. With 10 a limit switch has been schematised which delimits the downward stroke of the weights 9.
Vantaggiosamente secondo il presente trovato, sotto i pesi 9 è collegata una fune o catena 11 che si avvolge su di una puleggia di rinvio 12. Advantageously, according to the present invention, a rope or chain 11 is connected under the weights 9 which winds around a return pulley 12.
L'estremità libera della fune è collegata a mezzi atti ad applicare carichi aggiuntivi di elevata intensità, anche due o tre volte i carichi normali applicati nella fase di concentrica . The free end of the rope is connected to means suitable for applying additional loads of high intensity, even two or three times the normal loads applied in the concentric phase.
Più precisamente, il capo della fune è collegato, tramite un morsetto 13 ad un servoazionamento computerizzato 14 la cui funzione sarà meglio descritta in seguito. More precisely, the end of the rope is connected, by means of a clamp 13, to a computerized servo drive 14 whose function will be better described below.
Con riferimento alla figura 2 verrà ora descritta una variante di realizzazione particolarmente vantaggiosa per la trasformazione delle macchine di tipo noto già in commercio senza manomettere le macchine stesse. With reference to Figure 2, a particularly advantageous embodiment variant will now be described for converting known machines already on the market without tampering with the machines themselves.
Il servocomando 14 aziona una fune 15 che, tramite due pulegge di rinvio 16, si collega al settore circolare 6 di guida delle due funi. The servocontrol 14 activates a cable 15 which, by means of two return pulleys 16, is connected to the circular guide sector 6 of the two cables.
In questo caso si evita la connessione della fune 15 ai pesi 9 e quindi la macchina tradizionale atta ad una fase concentrica viene trasformata per poter effettuare una fase terapeutica in eccentrica. In this case the connection of the rope 15 to the weights 9 is avoided and therefore the traditional machine suitable for a concentric phase is transformed in order to be able to carry out an eccentric therapeutic phase.
Verrà ora descritto il funzionamento della macchina con riferimento alla prima forma realizzativa in quanto il funzionamento è perfettamente identico per entrambe le forme di realizzazione. The operation of the machine will now be described with reference to the first embodiment since the operation is perfectly identical for both embodiments.
Con riferimento alle figure 3 e 4 il paziente inizia a sollevare i piedi secondo la freccia A e di conseguenza anche i pesi secondo la freccia B; il morsetto 13 del servocomando 14 si sposterà secondo la freccia C. In questa fase di azione concentrica il servocomando eserciterà una leggera forza sulla fune 11 e quindi sui pesi più che altro per mantenere in tensione i la fune 11 o la corrispondente 15 della seconda forma di realizzazione.. With reference to figures 3 and 4, the patient begins to lift his feet according to arrow A and consequently also the weights according to arrow B; the clamp 13 of the servocontrol 14 will move according to the arrow C. In this phase of concentric action the servocontrol will exert a slight force on the rope 11 and therefore on the weights mainly to keep the rope 11 or the corresponding 15 of the second form under tension of realization ..
Nelle figure 5 e 6 il paziente ha raggiunto la fine della fase concentrica e si appresta ad iniziare la fase eccentrica illustrata nelle figure 7) e 8) in cui si invertono i versi delle frecce. In figures 5 and 6 the patient has reached the end of the concentric phase and is preparing to begin the eccentric phase illustrated in figures 7) and 8) in which the directions of the arrows are reversed.
Durante questa fase eccentrica il servocomando applica una elevata forza di trazione che può essere regolata nell'intensità e nella durata della sua applicazione secondo un programma inserito nel computer che comanda l'azionamento del servocomando. During this eccentric phase the servocontrol applies a high traction force which can be adjusted in the intensity and duration of its application according to a program inserted in the computer that controls the actuation of the servocontrol.
L'azione del servocomando cessa quando i pesi raggiungono il fine corsa come illustrato nelle figure 9) e 10) a completamento della fase di eccentrica oppure nel caso in cui il paziente rilasci improvvisamente. The action of the servocontrol ceases when the weights reach the limit stop as illustrated in figures 9) and 10) upon completion of the eccentric phase or in the event that the patient suddenly releases.
La macchina sopradescritta presenta i seguenti vantaggi: 1) possibilità di inserirsi nel movimento meccanico di una macchina già esistente; The machine described above has the following advantages: 1) possibility of being inserted into the mechanical movement of an already existing machine;
2) capacità di recupero rapido della posizione di stabilità in caso di rilascio improvviso da parte del soggetto che compie l'esercizio; 2) ability to quickly recover from the position of stability in the event of sudden release by the subject performing the exercise;
3) capacità di rilascio con minimo carico fino alla posizione di inizio della trazione concentrica; 3) release capacity with minimum load up to the starting position of the concentric traction;
4) possibilità di calibrare lo sforzo massimo di trazione eccentrica; 4) possibility of calibrating the maximum eccentric traction effort;
5) possibilità di regolare il tempo di trazione della fase eccentrica; 5) possibility to adjust the traction time of the eccentric phase;
6) regolazione del punto di inizio della trazione in eccentrica; 6) adjustment of the starting point of eccentric traction;
7) regolazione del punto di fine trazione in eccentrica; 8) possibilità di archiviazione di tutti i dati e parametri di lavoro. 7) eccentric adjustment of the traction end point; 8) possibility of archiving all data and working parameters.
Nella descrizione e nelle illustrazioni si è fatto specifico riferimento a macchine in cui l'azione sui pesi è esercitata dalle gambe, ma è evidente l'azione in eccentrica potrà essere applicata anche in macchine in cui l'azione è esercitata da braccia o altri distretti o segmenti corporei, tronco compreso In the description and illustrations specific reference has been made to machines in which the action on the weights is exerted by the legs, but it is evident that the eccentric action can also be applied in machines in which the action is exerted by arms or other districts. or body segments, including the trunk
