Description

DESCRIZIONE DESCRIPTION

La presente domanda di brevetto per invenzione industriale ha per oggetto un meccanismo, che chiameremo morsetto, avente la funzione di correggere la posizione del osso (3) sul quale si appoggiano le corde delle chitarre acustiche e classiche, generando una forza che si trasmette verticalmente. The present patent application for industrial invention relates to a mechanism, which we will call clamp, having the function of correcting the position of the bone (3) on which the strings of acoustic and classical guitars rest, generating a force that is transmitted vertically.

Nelle moderne chitarre, per amplificare il suono generato dalla vibrazione delle corde, si usa un sistema che capta le vibrazioni delle corde mediante un rilevatore piezoelettrico (4) posto sotto Fosso (3). In modern guitars, to amplify the sound generated by the vibration of the strings, a system is used that detects the vibrations of the strings by means of a piezoelectric detector (4) placed under Fosso (3).

Ma, come à ̈ noto agli operatori del settore, (musicisti e commercianti di strumenti musicali) quando Fosso (3) non si trova in perfetta posizione verticale (fig 3), si ha una limitata trasmissione delle vibrazioni delle corde. Questo à ̈ causato da un contatto parziale in tutta la lunghezza delFosso (3) sulla barretta piezoelettrica (4) provocando un cattivo bilanciamento in tutte le sei o dodici corde. Quanto scritto si può vedere nei disegni Fig 1 (perfetto contatto), nella Fig 2 osso spostato in avanti (parziale contatto). But, as is known to the operators of the sector, (musicians and traders of musical instruments) when Fosso (3) is not in a perfect vertical position (fig 3), there is a limited transmission of the vibrations of the strings. This is caused by a partial contact along the entire length of the Bone (3) on the piezoelectric rod (4) causing a bad balance in all six or twelve strings. What is written can be seen in the drawings Fig 1 (perfect contact), in Fig 2 bone moved forward (partial contact).

Lo spostamento in avanti delFosso (3) à ̈ dovuto alla forza di tiraggio delle corde (1) la quale trascina la punta estrema delFosso (3) in avanti (fig 2). Ogni corda à ̈ ancorata ad un blocco di legno duro incollato alla tavola armonica (12) chiamato ponticello (2) nel quale, in una apposita fresata, vengono alloggiati Fosso (3) e la barretta piezoelettrica (4). Le corde (1) sono ancorate al ponticello (2) mediante spinette (5) in plastica, chiamate Pins. The forward movement of the Ditch (3) is due to the pulling force of the ropes (1) which drags the extreme tip of the Ditch (3) forward (fig 2). Each string is anchored to a block of hard wood glued to the soundboard (12) called a bridge (2) in which Fosso (3) and the piezoelectric rod (4) are housed in a special milling. The strings (1) are anchored to the bridge (2) by means of plastic pins (5), called Pins.

Quindi fosso (3) spostato in posizione come da fig 2, provoca due difetti che rendono la chitarra insuonabile. La scarsa e non uniforme pressione sul rilevatore piezoelettrico (4) genera difetti di cattivo bilanciamento di suono sulle sei corde. Per es. le corde basse (4-5-6) hanno un volume di gran lunga differente delle prime tre (1-2-3). Sempre la posizione errata delfosso (3) genera un accorciamento della distanza tra il punto di aggancio al manico delle corde e fosso di appoggio, che influisce sulla non corretta intonazione dello strumento. Then ditch (3) moved into position as shown in fig 2, it causes two defects that make the guitar unsonable. The scarce and uneven pressure on the piezoelectric detector (4) generates defects of bad sound balance on the six strings. For example. the low strings (4-5-6) have a much different volume than the first three (1-2-3). Always the wrong position of the ditch (3) generates a shortening of the distance between the attachment point to the neck of the strings and the support ditch, which affects the incorrect intonation of the instrument.

CÃ ̈ anche da dire che ogni volta che si sostituiscono le corde, (cosa che accade anche spesso), alfatto della nuova accordatura fosso (3) tende a spostarsi in avanti, provocando tutti i difetti descritti in precedenza. It must also be said that every time the strings are replaced (which also happens often), the new tuning fosso (3) tends to move forward, causing all the defects described above.

Allo stato attuale, per riportare fosso (3) nella corretta posizione verticale ( vedi fig 1) si colpisce con un martello o con utensili di fortuna, nel senso indicato dalla freccia M. At present, to bring ditch (3) back to the correct vertical position (see fig 1), it is hit with a hammer or makeshift tools, in the direction indicated by the arrow M.

Tale operazione, specie se fatta da personale inesperto, danneggia lo strumento, provocando danni a volte irreversibili, come la rottura del ponticello (2) o la spaccatura della tavola armonica (12). This operation, especially if done by inexperienced personnel, damages the instrument, sometimes causing irreversible damage, such as the breaking of the bridge (2) or the cracking of the soundboard (12).

Lo scopo raggiunto dalla presente invenzione secondo il trovato, le cui caratteristiche peculiari sono puntualizzate nella allegata prima rivendicazione ed in quelle da essa dipendenti, Ã ̈ quello di porre rimedio agli inconvenienti sopra descritti, usando un sistema che deve trascinare fosso nella posizione verticale in maniera progressiva, senza traumi, per non danneggiare la chitarra. The object achieved by the present invention according to the invention, the peculiar characteristics of which are pointed out in the attached first claim and in those dependent on it, is to remedy the drawbacks described above, using a system which must drag the ditch into the vertical position in a manner progressive, without trauma, so as not to damage the guitar.

Il disegno N° 2 mostra lo schema del morsetto (6) che à ̈ composto da uno chassis (6), da una vite con filettatura metrica con testa a brugola (7) e con un piastrino metallico (8) che ha la funzione di ricevere la spinta dalla vite (7). Drawing N ° 2 shows the diagram of the terminal (6) which is composed of a chassis (6), a screw with metric thread with an Allen head (7) and a metal plate (8) which has the function of receive the thrust from the screw (7).

Una volta appoggiato il morsetto (6) con la parte anteriore comprendente sei fresate (9) attraverso le quali passano le corde (sia per la VI sia per la XII corde). In corrispondenza del punto (10) avviene il contatto in tutta la lunghezza dell’osso (8) come si può vedere nella figura 3 del disegno 1 . La vite (7) à ̈ comandata da una chiave a brugola (11), che ruotando in senso orario va a spingere il piastrino di metallo (8). Questo si pone in posizione inclinata e spinge lo chassis (6) a contatto della tavola armonica (12) della chitarra. Ora si deve continuare la manovra fino a mrttere l’osso in posizione di verticale perfetta, dando un contatto massimo tra osso (8) e barretta piezoelettrica (4)· Once the clamp (6) is placed with the front part comprising six grooves (9) through which the strings pass (both for the VI and for the XII strings). In correspondence of the point (10) the contact takes place along the whole length of the bone (8) as can be seen in figure 3 of drawing 1. The screw (7) is controlled by an Allen key (11), which, by turning clockwise, pushes the metal plate (8). This is placed in an inclined position and pushes the chassis (6) in contact with the soundboard (12) of the guitar. Now the maneuver must be continued until the bone is in a perfect vertical position, giving maximum contact between the bone (8) and the piezoelectric rod (4) ·

I due scopi descritti secondo il trovato; per posizionare l’osso (3) in perfetta verticale, onde avere la massima pressione sulla barretta piezoelettrica (4) e mantenere il diapason nella misura originale dando allo strumento una ottava entro i limiti di tolleranza, sono stati ottenuti egregiamente senza creare traumi e danni allo strumento. The two objects described according to the invention; to position the bone (3) in perfect vertical position, in order to have the maximum pressure on the piezoelectric rod (4) and to keep the tuning fork in the original size giving the instrument an octave within the tolerance limits, have been obtained very well without creating trauma and damage to the instrument.
