Abstract

"DISPOSITIVO DE DUPLA REPETIçãO NOS PIANOS VERTICAIS E DE ACRéSCIMO DE RESISTêNCIA AO TOQUE EM TECLADOS DE PIANOS VERTICAIS" O presente pedido refere-se a um dispositivo, para utilização em pianos verticais, que permite ao executante repetir uma nota que acabou de ser tocada sem a necessidade de retornar a tecla à posição original (posição de repouso), exigindo para isto um relaxamento mínimo, propiciando maior agilidade durante a execução. O dispositivo oferece, ainda, maior resistência ( "peso" ) para todo o teclado, transmitindo maior segurança e firmeza para os dedos do executante. Deste modo, o dispositivo faz com que a repetição do piano vertical seja idêntica à do piano de cauda. Por outro lado, oferece uma resistência de toque igual ou muito próxima àquela proporcionada também por um mecanismo de piano de cauda. O dispositivo ora proposto consiste de uma buqueta (1), came (2), tensionador (3) de diferentes espessuras e resistências, fixador (22) que, formando um todo, são acoplados ao mecanismo do piano vertical, bem como alterações essenciais no mecanismo, tais como: parafuso (16) de regulagem da posição da baioneta (9), modificação na angulação da noz (10) em relação ao cabo (12) do martelo (14) e ao cabo (13) da nazeta (8), e nazeta (8), contra-martelo (7) e couro (11) da noz (10) com formatos e posicionamentos diferenciados, bem como couro de amortecimento"DOUBLE REPETITION DEVICE ON VERTICAL PIANOS AND TOUCH RESISTANCE TO VERTICAL PIANO KEYBOARDS" This application refers to a device, for use on vertical pianos, that allows the performer to repeat a note that has just been played without the need to return the key to its original position (resting position), requiring minimal relaxation for this, providing greater agility during execution. The device also offers greater resistance ("weight") for the entire keyboard, transmitting greater security and firmness to the performer's fingers. In this way, the device makes the vertical piano repetition identical to that of the grand piano. On the other hand, it offers a touch resistance equal to or very close to that provided also by a grand piano mechanism. The device now proposed consists of a bouquet (1), cam (2), tensioner (3) of different thicknesses and resistances, fastener (22) which, forming a whole, are coupled to the upright piano mechanism, as well as essential changes in the mechanism, such as: screw (16) for adjusting the bayonet position (9), changing the angle of the nut (10) in relation to the handle (12) of the hammer (14) and the handle (13) of the nut (8) , and walnut (8), counter-hammer (7) and walnut leather (11) with different shapes and positions, as well as cushioning leather
