Description

Descrizione di brevetto per invenzione industriale dal titolo: Patent description for industrial invention entitled:

“Bicicletta variabile” "Variable bicycle"

Oggetto della presente invenzione è una bicicletta, veicolo a due ruote di cui una anteriore ed una posteriore, a propulsione muscolare umana per mezzo di pedali azionati dagli arti inferiori, sulla quale l'appoggio del corpo umano avviene in posizione prona e ventrale, in particolare sul lato frontale di bacino e sterno, per mezzo di strutture idoneamente imbottite od elastiche. I piedi agiscono sui due pedali, che agiscono direttamente sullo stesso asse di rotazione della ruota posteriore, alla maniera dei noti monocicli. Non è presente alcuna catena od altro dispositivo di trasmissione. Le mani trovano appoggio in due manubri, uno destro ed uno sinistro, fìssati ai rispettivi bracci della forcella anteriore, od anche alla parte superiore di detta forcella anteriore; detti manubri sono ampiamente spostabili durante la marcia, per permettere, nella posizione all’indietro, di rizzarsi sui pedali staccando bacino e sterno dai loro appoggi, e consentire così un assetto più efficace nelle salite ripide, assetto consentito anche dalle biciclette tradizionali. The subject of the present invention is a bicycle, a two-wheeled vehicle, one of which is front and rear, with human muscular propulsion by means of pedals operated by the lower limbs, on which the human body is supported in a prone and ventral position, in particular on the front side of the pelvis and sternum, by means of suitably padded or elastic structures. The feet act on the two pedals, which act directly on the same axis of rotation of the rear wheel, in the manner of the known unicycles. There is no chain or other transmission device. The hands rest on two handlebars, one right and one left, fixed to the respective arms of the front fork, or also to the upper part of said front fork; these handlebars are widely movable during travel, to allow, in the rearward position, to stand up on the pedals by detaching the pelvis and sternum from their supports, and thus allow a more effective attitude on steep climbs, a position also allowed by traditional bicycles.

Sono note biciclette, in cui l'appoggio verticale del bacino su una sella, unito alla necessità, nella ricerca di velocità, di inclinare il busto in avanti, genera almeno quattro inconvenienti: Bicycles are known, in which the vertical support of the pelvis on a saddle, combined with the need, in the search for speed, to tilt the torso forward, generates at least four drawbacks:

la pressione di quasi l'intero peso del corpo su un'area di pochi centimetri quadrati, proprio nella regione degli organi genitali, causa dolore e malattie; the pressure of almost the entire weight of the body on an area of a few square centimeters, right in the region of the genital organs, causes pain and disease;

la colonna vertebrale si curva in avanti, disegnando una S opposta a quella naturale: ne risulta indebolita ed esposta a traumi; the vertebral column bends forward, drawing an S opposite to the natural one: it is weakened and exposed to trauma;

le spalle sono costrette a stringersi e spingersi in avanti, limitando l'espansione del torace e la respirazione; the shoulders are forced to tighten and push forward, limiting the expansion of the chest and breathing;

il petto tende ad avvicinarsi alle ginocchia, comprimendo il diaframma, limitando a sua volta la respirazione e forzando l'apparato muscoloscheletrico con angoli non ottimali, tali che producono meno forza. Oltre alle biciclette tradizionali, sono note biciclette, su cui il corpo umano giace in posizione supina, prona o quasi prona, poggiando il bacino su selle o appoggi dorsali o frontali; in alcune di esse anche la parte superiore del busto è sostenuta frontalmente, mentre gli arti inferiori agiscono su pedali, connessi alla ruota motrice con o senza dispositivi di trasmissione. In tutte queste altre biciclette note gli arti superiori poggiano su manubri fissi, che non danno al corpo umano la possibilità di variare di molto la propria posizione, né la propria azione sui pedali. the chest tends to come closer to the knees, compressing the diaphragm, limiting in turn breathing and forcing the musculoskeletal system with non-optimal angles, such that they produce less force. In addition to traditional bicycles, bicycles are known on which the human body lies in a supine, prone or almost prone position, resting the pelvis on saddles or dorsal or front supports; in some of them the upper part of the torso is also supported frontally, while the lower limbs act on pedals, connected to the driving wheel with or without transmission devices. In all these other known bicycles, the upper limbs rest on fixed handlebars, which do not give the human body the possibility of greatly varying its position, nor its action on the pedals.

Scopo della presente invenzione è di fabbricare biciclette che, oltre a porre la persona umana in una postura prona e distesa, molto più sana, potente ed aerodinamica che nelle biciclette tradizionali, grazie ai manubri di assetto ampiamente variabile, consentono anche una ampia mutazione della postura, con l'atto di staccare completamente il corpo dal telaio del veicolo. In questa ultima postura la o il ciclista scarica la maggior parte del proprio peso unicamente sui pedali ed esercita una spinta completamente diversa sul veicolo, particolarmente adatta alla marcia in salita. Inoltre il corpo, non costretto in un'unica posizione, può muoversi molto più liberamente ed ampiamente, cosa che migliora l'effetto benefico dell'esercizio fisico e consente viaggi più lunghi e meno faticosi. The purpose of the present invention is to manufacture bicycles which, in addition to placing the human person in a prone and relaxed posture, much healthier, more powerful and aerodynamic than in traditional bicycles, thanks to the widely variable handlebars, also allow a wide change of posture. , with the act of completely detaching the body from the vehicle chassis. In this last posture, the cyclist unloads most of his weight solely on the pedals and exerts a completely different thrust on the vehicle, particularly suitable for uphill riding. Furthermore, the body, not forced into a single position, can move much more freely and widely, which improves the beneficial effect of physical exercise and allows longer and less tiring journeys.

I disegni uniti sono dati a titolo esemplificativo e non limitativo. The joined drawings are given by way of non-limiting example.

La figura 1 mostra la bicicletta oggetto della presente invenzione in vista laterale sinistra, in cui la persona ha portato i manubri in posizione “indietro” e può così scaricare in libertà il proprio peso sui pedali, posizione consentita già anche dalle biciclette tradizionali. Figure 1 shows the bicycle object of the present invention in a left side view, in which the person has brought the handlebars to the "back" position and can thus freely unload his weight on the pedals, a position already permitted by traditional bicycles.

La figura 2 mostra la bicicletta oggetto della presente invenzione in vista laterale sinistra, in cui la persona ha portato i manubri in posizione “avanti” e può cosi distendersi in avanti e poggiare bacino e sterno su appoggi imbottiti, o comunque elastici e confortevoli; tale posizione consente movimenti consoni alla struttura del corpo umano, una maggiore rilassatezza ed una ottima forma aerodinamica. Figure 2 shows the bicycle object of the present invention in left side view, in which the person has brought the handlebars to the "forward" position and can thus lie forward and rest the pelvis and sternum on padded, or in any case elastic and comfortable, supports; this position allows movements in keeping with the structure of the human body, greater relaxation and an excellent aerodynamic shape.

La figura 3 mostra la bicicletta oggetto della presente invenzione, senza nessuna persona su di essa, in vista dall'alto e con i manubri in posizione “avanti”. Figure 3 shows the bicycle object of the present invention, without any person on it, in top view and with the handlebars in the "forward" position.

La figura 4 mostra il particolare tecnico della estremità superiore del manubrio destro, identico e speculare a quello sinistro, visto in diverse posizioni sia di lato dairinterno( C e D ), che da sopra ( A e B ). Figure 4 shows the technical detail of the upper end of the right handlebar, identical and specular to the left one, seen in different positions both from the inside (C and D) and from above (A and B).

Claims

Claims. 1 - Bicicleta, two-wheeled vehicle, of which one front 1 and one rear 2, connected and fixed by a metal or other material frame 10, consisting of a central part that allows adjustments both in length and height of the supports 5 and 6, as well as adjustments of its own length. Said frame 10 ends at the front with a front fork 11, free to rotate to the left and to the right and to which the front wheel 1 is fixed, and at the rear with a rear fork 12, to which the rear wheel 2 is fixed. human muscle by means of two pedals 3, one left and one right, operated by the lower limbs, which act directly on the hub 4 of the rear wheel 2, without a chain or other transmission device. On deta bicicleta the human body rests in two distinct positions, which characterize deta bicicleta, freely chosen by or by the cyclist during the march and changed without having to stop the vehicle. The first of the two positions, "extended", with dumbbells in the "forward" position is illustrated in figure 2: the pelvis rests frontally on a transverse support 5, consisting of a padded panel with a cushion, or a frame at the ends of which it is stretched a textile band, or any other element designed to ensure support and comfort; the sternum rests frontally on a longitudinal support 6, consisting of a panel filled with a cushion, or any other element designed to ensure support and comfort; the hands rest on two handlebars 7, one left and one right, fixed to the two supports 8, located on the two left and right arms of the front fork 11, or on the upper end of said front fork 11, or constituting the two ends of a single handlebar attached to the upper end of the front fork 11, and able to rotate forward and backward, or consisting of any other element, designed to ensure the support of the upper limbs and to be moved between the "forward" and "backward" positions. The second position, "detached", with handlebars in the "back" position is illustrated in figure 1: the human body is detached from the frame of said bicycle and rests solely on the pedals 3 by means of the feet, and on the handlebars 7 by the hands . 2 - Bicycle according to claim 1, characterized in that said handlebars 7 can rotate on supports 8, passing between the two extreme positions "forward", illustrated in figures 2 and 3, and "backward", illustrated in figure 1. mechanical solutions that allow the change between the said two extreme positions "forward" and "back", keeping the hands on the use of the various controls placed on the handlebars, easy change even while the vehicle is running, and the locking of the handlebars in said positions extreme, may be different and do not limit the present invention. The solution illustrated in figure 4 consists of the presence, for each handlebar 7, of two metal tubes with a square section, aligned on a longitudinal vertical plane, hinged below the support 8 by means of two parallel pins and above the plate 25 also by means of of two parallel pins. The handle 9 is fixed to said plate 25, which can therefore move forward and backward, keeping its position constant with respect to a horizontal plane. The locking of each of the two said handlebars 7 in each of the two "forward" and "backward" positions is illustrated in figure 4. The handle 9 rotates on a vertical pin 13 fixed to the plate 25. When the handle 9 is rotated backwards (A ), its inner end 14 blocks the upper end of the front of the two said square tubes which make up the handlebar 7, preventing the said handlebar 7 from moving, both when it is in the "forward" and "backward" position. Conversely, when the handle 9 is rotated forward (B), its internal end 14 no longer stops the movement of the two said square tubes that make up the handlebar 7, which can thus be moved between the said "forward" positions (C) and "back" (D).
