Description
Descrizione dell'Invenzione Industriale dal titolo: DISPOSITIVO DI ALLUNGAMENTO DELLE PEDALIERE CICLISTICHE IN FASE DI SPINTA Description of the Industrial Invention entitled: DEVICE FOR EXTENDING THE CYCLING PEDALS IN THE PUSH PHASE
TESTO DELLA DESCRIZIONE TEXT OF THE DESCRIPTION
L'invenzione concerne un dispositivo di allungamento delle pedaliere, particolarmente per biciclette da corsa, atto a determinare un incremento del braccio della forza applicata ai pedali ed un conseguente aumento del momento Trasmesso alle ruote, per aumentare l'efficienza della pedalata. The invention relates to a device for extending the pedal boards, particularly for racing bicycles, capable of causing an increase in the arm of the force applied to the pedals and a consequent increase in the moment transmitted to the wheels, to increase pedaling efficiency.
L'invenzione nasce dall'esigenza di variare automaticamente e solo nella fase attiva della pedalata il momento della forza applicata. The invention arises from the need to automatically vary the moment of the applied force only in the active pedaling phase.
Lo scopo si raggiunge con il dispositivo secondo l'invenzione, comprendente due pedivelle dotate di guide scanalate per il passaggio di perni di bloccaggio, inseriti in fori passanti presenti sulle pedaliere rese in tal modo scorrevoli e con cuscinetti atti a ricevere detti perni, montati su un supporto attraversato eccentricamente dall'albero cui sono collegate le pedivelle stesse, in modo tale che l'eccentricità dei centri di rotazione delle pedivelle attorno all'asse e dei perni all'interno dei cuscinetti, determina, in fase di Il funzionamento del dispositivo secondo l'invenzione può essere cosi descritto: The object is achieved with the device according to the invention, comprising two cranks equipped with grooved guides for the passage of locking pins, inserted in through holes present on the pedal boards thus made sliding and with bearings suitable for receiving said pins, mounted on a support crossed eccentrically by the shaft to which the cranks themselves are connected, in such a way that the eccentricity of the centers of rotation of the cranks around the axis and of the pins inside the bearings, determines, during the operation of the device according to the invention can be described as follows:
- la rotazione della pedivella 1 attorno all'albero A, causa uno scorrimento lineare del perno di bloccaggio 3 nella guida scanalata 2 della pedivella 1 conseguente al contemporaneo movimento rotatorio dello stesso all'interno del cuscinetto 2 cui risulta vincolato; - the rotation of the pedal crank 1 around the shaft A causes a linear sliding of the locking pin 3 in the grooved guide 2 of the pedal crank 1 consequent to the simultaneous rotational movement of the same inside the bearing 2 to which it is constrained;
il movimento del perno 3, collegato alla pedaliera 4 attra-verso i fori passanti 5, consente lo scorrimento della stessa sulla pedivella 1; the movement of the pin 3, connected to the pedal board 4 through the through holes 5, allows it to slide on the pedal crank 1;
- l'eccentricità dei centri di rotazione della pedivella 1 attorno all'asse A, e del perno 3 all'interno del cuscinetto 2, determina, in fase di spinta, un allungamento delle pedaliere 4 in grado di garantire un incremento del braccio della forza applicata ai pedali P, ed un conseguente aumento del momento trasmesso alle ruote. - the eccentricity of the rotation centers of the pedal crank 1 around the axis A, and of the pin 3 inside the bearing 2, determines, during the thrust phase, an elongation of the pedals 4 capable of guaranteeing an increase in the force of the arm applied to the pedals P, and a consequent increase in the moment transmitted to the wheels.
In fase di riposo si ha, invece, una diminuzione della lunghezza della pedivella 1. In the rest phase, however, there is a decrease in the length of the crank arm 1.
Naturalmente, fermo restando il principio del trovato, le forme di realizzazione e i particolari di costruzione potranno essere ampiamente variati rispetto a quanto descritto e illustrato, senza per questo uscire dall'ambito della presente invenzione. Naturally, the principle of the invention remaining the same, the embodiments and construction details may be varied widely with respect to those described and illustrated, without thereby departing from the scope of the present invention.
