Abstract

Un aparato tocadiscos que comprende un brazo fonocaptor destinado a ser controlado por un disco de mando, estando dispuesto un acoplamiento de sobrecarga entre el brazo fonocaptor y el disco de mando, cuyo acoplamiento comprende dos miembros de acoplamiento que son pivotables uno con relación a otro alrededor de un eje común contra la fuerza de un muelle partiendo de una posición neutra de cuyos miembros un primer miembro de acoplamiento coopera con el disco de mando y un segundo miembro de acoplamiento con el brazo fonocaptor, caracterizado porque cada miembro de acoplamiento comprende una guía que está concéntricamente curvada alrededor del eje común, coincidiendo las guías de los miembros de acoplamiento en la posición neutra, vista paralelamente al eje, mientras que ha sido deslizado sobre las guías un muelle helicoidal continuo, cuyos extremos respectivos se apoyan contra partes extremas de las guías en la posición neutra.
