DESCRIZIONE DESCRIPTION
TITOLO: DISPOSITIVO DI ALLENAMENTO CICLISTICO INDOOR E METODO PER LA MISURA DELLA POTENZA TITLE: INDOOR CYCLING TRAINING DEVICE AND METHOD FOR MEASURING POWER
CAMPO DI APPLICAZIONE DELL’INVENZIONE FIELD OF APPLICATION OF THE INVENTION
Il presente trovato si inserisce nel campo dei dispositivi di allenamento indoor, con particolare riferimento al ciclismo. The present invention is part of the field of indoor training devices, with particular reference to cycling.
STATO DELL’ARTE STATE OF THE ART
Sono noti dispositivi di allenamento che possono essere predisposti di ausilio, o in sostituzione, della ruota posteriore della bicicletta, così da permettere allenamenti indoor senza dover effettuare l’uscita su strada o sterrato oppure semplicemente per il riscaldamento prima di una gara. Training devices are known which can be provided as an aid to, or as a replacement for, the rear wheel of the bicycle, so as to allow indoor training without having to go out on the road or dirt or simply for warming up before a race.
I dispositivi in ausilio della ruota posteriore sono generalmente composti da un telaio che tiene sollevata da terra la ruota posteriore della bicicletta un sistema frenante premuto direttamente contro la ruota. The devices supporting the rear wheel are generally composed of a frame that keeps the rear wheel of the bicycle raised from the ground, a braking system pressed directly against the wheel.
In questo caso i difetti sono: In this case the defects are:
• il consumo del copertone; â € ¢ tire wear;
• l’attrito tra copertone e sistema di frenatura variabile e non misurabile. A seconda di quanto viene premuto il sistema di frenatura contro la ruota, si avrà un certo attrito che qualsiasi dispositivo di misura della potenza applicato al sistema di frenatura, non potrà quantificare e quindi la lettura della potenza sarà sempre approssimativa. â € ¢ The friction between the tire and the braking system is variable and not measurable. Depending on how much the braking system is pressed against the wheel, there will be a certain friction that any power measuring device applied to the braking system will not be able to quantify and therefore the power reading will always be approximate.
Il vantaggio di questa tipologia di dispositivi à ̈ la maggiore semplicità costruttiva. The advantage of this type of device is the greater construction simplicity.
I dispositivi in sostituzione della ruota posteriore sono generalmente composti da un telaio fisso, un mozzo con i pignoni in sostituzione di quelli della ruota e un sistema frenante. The devices replacing the rear wheel are generally composed of a fixed frame, a hub with sprockets to replace those of the wheel and a braking system.
Anche questi dispositivi sono dotati di sistemi di frenatura così da simulare lo sforzo della pedalata e ottenere un allenamento efficace. These devices are also equipped with braking systems so as to simulate the effort of pedaling and obtain an effective workout.
Tra i sistemi di frenatura sono noti quelli: Among the braking systems are known those:
- meccanici, dove l’effetto frenante à ̈ ottenuto mediante attrito fra due parti in movimento relativo, il cui difetto principale à ̈ l’usura degli elementi d’attrito; - mechanical, where the braking effect is obtained by friction between two parts in relative movement, the main defect of which is the wear of the friction elements;
- aerodinamici, dove l’effetto frenante à ̈ ad opera di ventole. In questo caso gli inconvenienti principali sono: - aerodynamic, where the braking effect is due to the fans. In this case the main drawbacks are:
• la rumorosità . Dato che l’allenamento indoor viene eseguito per lo più in casa, la generazione di rumore potrebbe recare disturbo ai vicini o a se stessi; â € ¢ the noise. Since indoor training is performed mostly indoors, the generation of noise could disturb neighbors or oneself;
• la generazione di correnti d’aria, che nel caso di allenamento durante il periodo invernale, potrebbe non solo essere fastidioso, ma potrebbe comportare malanni quali, ad esempio, contratture muscolari causate dallo sbalzo di temperatura tra il muscolo e la corrente d’aria. â € ¢ the generation of drafts, which in the case of training during the winter period, could not only be annoying, but could lead to ailments such as, for example, muscle contractures caused by the sudden change in temperature between the muscle and the current of air.
• magnetici a correnti parassite, in cui la frenatura viene creata tramite un magnete o un elettromagnete, che genera all’interno di un disco di frenatura delle correnti parassite. La variazione di frenatura viene fatta variando la posizione del magnete rispetto al disco di frenatura o variando la corrente nell’elettromagnete. â € ¢ Eddy current magnetic, in which the braking is created by a magnet or an electromagnet, which generates eddy currents inside a braking disk. The braking variation is made by varying the position of the magnet with respect to the braking disc or by varying the current in the electromagnet.
Scopo del presente trovato à ̈ quello di risolvere i problemi sopra citati unendo un dispositivo in sostituzione della ruota posteriore con un sistema frenante a correnti parassite ad azionamento magnetico e un congegno atto a rilevare in maniera precisa la potenza di pedalata generata a seguito di detta frenatura magnetica, che si caratterizza per quanto previsto nelle sotto riportate rivendicazioni. The purpose of the present invention is to solve the aforementioned problems by combining a device replacing the rear wheel with a magnetic-actuated eddy-current braking system and a device capable of accurately detecting the pedaling power generated as a result of said braking. magnetic, which is characterized by what is foreseen in the following claims.
Questa ed altre caratteristiche risulteranno maggiormente evidenziate dalla descrizione seguente di una forma di realizzazione illustrata, a puro titolo esemplificativo e non limitativo, nelle unite tavole di disegno. This and other characteristics will become more evident from the following description of an embodiment illustrated, purely by way of non-limiting example, in the accompanying drawing tables.

Con particolare riferimento alle figure, con 1 Ã ̈ globalmente indicato un dispositivo per allenamento ciclistico indoor con frenatura di tipo magnetico con rilevamento potenza di pedalata del tipo comprendente un telaio 2, sistemi di supporto 3, un sistema 4 frenante, un sistema 5 di trasmissione del moto ed un sistema 6 di misura della potenza di pedalata. With particular reference to the figures, 1 globally indicates a device for indoor cycling training with magnetic braking with pedaling power detection of the type comprising a frame 2, support systems 3, a braking system 4, a transmission system 5 of the motion and a system 6 for measuring the pedaling power.
Come mostrato in figura 1, una volta tolta la ruota posteriore alla bicicletta 100, il dispositivo si sostituisce alla ruota. As shown in Figure 1, once the rear wheel has been removed from the bicycle 100, the device replaces the wheel.
In accordo con la forma preferita illustrata nelle figure allegate, il telaio 2 Ã ̈ costituito da tre tubolari 2a, 2b, 2c di sezione rettangolare uniti tra loro. In accordance with the preferred form illustrated in the attached figures, the frame 2 is made up of three rectangular section tubes 2a, 2b, 2c joined together.
Su detto telaio 2 à ̈ fissato il sistema di supporto laterale 3 e un perno conico 7 la cui funzione à ̈ quella di rendere più rigido il collegamento tra la bicicletta 100 e il dispositivo 1. The lateral support system 3 and a conical pin 7 are fixed on said frame 2, the function of which is to make the connection between the bicycle 100 and the device 1 more rigid.
Alla base del telaio à ̈ fulcrata un’asta 14 che porta sull’estremità libera un sensore 15 di cadenza di pedalata. A rod 14 is pivoted at the base of the frame which carries a pedaling cadence sensor 15 on the free end.
Sulla sommità del telaio 2c à ̈ calettato la prima parte del sistema 5 di trasmissione del moto, detto sistema 5 à ̈ costituito da una serie di pignoni 8 coassiali ad una puleggia primaria 9 o motrice ed à ̈ libero di ruotare. On the top of the frame 2c the first part of the motion transmission system 5 is keyed, said system 5 is made up of a series of pinions 8 coaxial to a primary pulley 9 or driving and is free to rotate.
Un elemento flessibile 10, o cinghia, à ̈ posta in tensione tra la puleggia motrice 9 e la puleggia condotta 11, fissata sull’estremità terminale di un albero 19 montato su cuscinetti e che attraversa orizzontalmente il tubolare 2c verticale. All’estremità opposta, l’albero 19 porta calettato un gruppo volano composto da un volano 13b e un secondo disco 13, di metallo, solitamente fatto di alluminio o rame. A flexible element 10, or belt, is placed in tension between the driving pulley 9 and the driven pulley 11, fixed on the terminal end of a shaft 19 mounted on bearings and which crosses the vertical tubular 2c horizontally. At the opposite end, shaft 19 has a keyed flywheel assembly consisting of a flywheel 13b and a second metal disc 13, usually made of aluminum or copper.
Il disco 13, l’elettromagnete 18 e il supporto 20 costituiscono il sistema 4 frenante. L’elettromagnete 18 à ̈ fissato sul tubolare 2b, grazie ad un supporto 20 che funge da circuito magnetico. The disc 13, the electromagnet 18 and the support 20 constitute the braking system 4. The electromagnet 18 is fixed on the tubular 2b, thanks to a support 20 which acts as a magnetic circuit.
Il funzionamento di detto sistema 4 frenante si basa sul principio delle correnti parassite. The operation of said braking system 4 is based on the eddy current principle.
Il sistema 6 di misura della potenza di pedalata à ̈ fissato al tubolare 2c e comprende una cella di carico 12 ed un sensore 17 di velocità angolare. In particolare, la porzione terminale della cella di carico 12 comprende un cuscinetto 12b libero di ruotare; detto cuscinetto 12b à ̈ preposto ad essere posizionato contro un tratto dell’elemento flessibile 10, in tensione tra la puleggia motrice 9 e la puleggia condotta 11. The pedaling power measuring system 6 is fixed to the tubular 2c and comprises a load cell 12 and an angular speed sensor 17. In particular, the terminal portion of the load cell 12 comprises a bearing 12b free to rotate; said bearing 12b is designed to be positioned against a portion of the flexible element 10, in tension between the driving pulley 9 and the driven pulley 11.
Detta cella di carico 12 non ha funzione di tensionatore della cinghia 10, ma ha lo scopo di acquisire le forze agenti sulla cinghia stessa. Said load cell 12 has no function of tensioning the belt 10, but has the purpose of acquiring the forces acting on the belt itself.
Operativamente, una volta rimossa la ruota posteriore di una bicicletta 100 Ã ̈ possibile agganciare le forcelle posteriori 101 della stessa bicicletta 100 al dispositivo 1 oggetto del presente trovato e ingranare la catena 102 ai pignoni 8. Operationally, once the rear wheel of a bicycle 100 has been removed, it is possible to hook the rear forks 101 of the same bicycle 100 to the device 1 according to the present invention and to engage the chain 102 with the sprockets 8.
Durante l’allenamento il sensore 15 di cadenza di pedalata, posto sull’asta 14, rileva il numero di pedalate eseguite e lo trasmette in ingresso ad un modulo di acquisizione dati 16 interfacciato a sua volta con un computer. During training, the pedaling cadence sensor 15, placed on the rod 14, detects the number of pedal strokes performed and transmits it to a data acquisition module 16 interfaced in turn with a computer.
Insieme a detto segnale (cadenza di pedalata) in ingresso al modulo di acquisizione dati 16 vi sono altri due parametri: Together with said signal (pedaling cadence) at the input of the data acquisition module 16 there are two other parameters:
- la forza F trasmessa al rullino 12b e rilevato dalla cella di carico 12; - the force F transmitted to the roller 12b and detected by the load cell 12;
-la velocità angolare del volano 13b espressa in giri/minuto, e rilevata dal sensore 17. - the angular speed of the flywheel 13b expressed in revolutions / minute, and detected by the sensor 17.
In sostanza, con riferimento allo schema delle forze mostrato in figura 5, sul lato della cinghia 10 a contatto con il cuscinetto 12b della cella di carico 12 nei due tratti a monte e a valle della cella 12 stessa nascono due forze T1 e T2. Basically, with reference to the force diagram shown in Figure 5, two forces T1 and T2 arise on the side of the belt 10 in contact with the bearing 12b of the load cell 12 in the two portions upstream and downstream of the cell 12 itself.
Con F à ̈ indicata la risultante della forza impressa sulla cella di carico 12 la cui direzione à ̈ perpendicolare alla cella di carico 12. In particolare: F indicates the resultant of the force impressed on the load cell 12 whose direction is perpendicular to the load cell 12. In particular:
<F = T1 cos>α<+ T2 cos>β <F = T1 cos> Î ± <+ T2 cos> β
Detta forza F, espressa in Newton così come T1 e T2, à ̈ la forza ricavata dalla cella di carico 12. Said force F, expressed in Newton as well as T1 and T2, is the force obtained from the load cell 12.
Dal momento che la tensione T della cinghia 10 à ̈ la stessa su tutto il tratto che va tra la puleggia motrice 9 e la puleggia condotta 11, si può scrivere che Since the tension T of the belt 10 is the same over the entire stretch that goes between the driving pulley 9 and the driven pulley 11, it can be written that
T1 = T2 = T T1 = T2 = T.
L’espressione di prima allora si può semplificare in The former expression can then be simplified to
<F = T1 cos>α<+ T2 cos>β<= T (cos>α<+ cos>β<).><F = T1 cos> Î ± <+ T2 cos> β <= T (cos> Î ± <+ cos> β <).>
E quindi il valore della tensione T risulta essere: And therefore the value of the voltage T turns out to be:
<T = F / (cos>α<+ cos>β<).><T = F / (cos> Î ± <+ cos> β <).>
Una volta ricavato questo dato la coppia M trasmessa alla puleggia condotta 11 Ã ̈: Once this data has been obtained, the torque M transmitted to the driven pulley 11 is:
<M = T x R2 = (F x R2) / (cos>α<+ cos>β<),><M = T x R2 = (F x R2) / (cos> Î ± <+ cos> β <),>
dove R2 à ̈ il raggio primitivo della puleggia condotta 11 espresso in metri. Detto raggio primitivo à ̈ un dato di progetto, così come α e β. where R2 is the primitive radius of the driven pulley 11 expressed in meters. Said primitive radius is a design datum, as well as Î ± and β.
La potenza di pedalata, espressa in watt, Ã ̈ dunque pari a: The pedaling power, expressed in watts, is therefore equal to:
P = M x rpm x 2Ï€/60 P = M x rpm x 2Ï € / 60
<= [(F x R2) / (cos>α<+ cos>β<)] x [2 x Ï€ x velocità / 60]><= [(F x R2) / (cos> Î ± <+ cos> β <)] x [2 x Ï € x speed / 60]>
In cui rpm, espressa in giri al minuto, à ̈ la velocità di rotazione ricavata dal sensore 17. In which rpm, expressed in revolutions per minute, is the rotation speed obtained from sensor 17.
Come mostrato in figura 4, oltre agli ingressi analogici sopracitati, in ingresso al modulo di acquisizione dati 16 vi sono anche ingressi esterni al dispositivo 1, in particolare vi sono: As shown in figure 4, in addition to the aforementioned analog inputs, at the input of the data acquisition module 16 there are also inputs external to the device 1, in particular there are:
- dati inviati da un ricevitore cardiofrequenzimetro; - data sent by a heart rate monitor receiver;
- dati inviati da un potenziometro; - data sent by a potentiometer;
- dati impostati mediante un pulsante P1 presente per gestire alcune funzioni del programma senza dover ricorrere alla tastiera del computer. - data set using a P1 button present to manage some program functions without having to use the computer keyboard.
In accordo con la presente invenzione, i suddetti dati in ingresso al modulo acquisizione dati 16 e, quindi, successivamente in ingresso al computer, vengano elaborati da un apposito software fanno sì che come parametro in uscita via sia la regolazione dell’elettromagnete 18 di frenatura. In accordance with the present invention, the aforementioned input data to the data acquisition module 16 and, therefore, subsequently input to the computer, are processed by a suitable software, so that as an output parameter there is the regulation of the electromagnet 18 braking.
