Abstract (en)
1. A harp of the type comprising a set of strings (1) stretched between an arm called a console (2) and a resonator forming a soundboard (3), which is connected at the level of the abutment of the harp, the vibrating length of which may be adjusted by means of pairs of superimposed forks (7, 8), which are designed to grip the strings and which are actuated by a mechanism which is accommodated in a pillar (6), and which is connected to pedals (9) arranged in the pedestal (5) of the harp, characterised in that the mechanism for actuating the forks (7, 8) comprises, for each of the seven degrees of the scale, a double-acting transmission device comprising a first traction cable (11), which is connected on the one hand to a series of first upper forks (7) effecting a gripping of the associated strings in order to obtain a natural tone, and on the other hand to a rocking control member, and comprising a second traction cable (14), which is connected on the one hand to a series of second lower forks (8) effecting a gripping of the associated strings in order to obtain a sharp tone, and on the other hand to a pedal (9), the said second cable (14) actuating the said-rocking control member, so as to convert the traction exerted on the said cable (14) into two successive angular movements of the upper and then the lower forks.
Abstract (fr)
Le problème technique posé consiste à réaliser pour une harpe un mécanisme perfectionné de réglage des sons délivrés par les cordes. Le mécanisme d'actionnement des fourchettes (7,8) se compose, pour chacun des sept degrés de la gamme, d'un dispositif de transmission à double action constitué d'au moins un câble de tracton dont un brin (11) est relié à une série de premières forchettes supérieures (7) réalisant un pincement des cordes associées pour l'obtention du son bécarre, l'autre brin (14) étant relié à une série de secondes fourchettes inférieures (8) réalisant un pincement des cordes associées pour l'obtention du son dièse, ce câble étant lui-même relié à la pédale (9) par un organe de commande basculant divisant la traction exercée sur le câble en deux mouvements angulaires successifs des fourchettes supérieures et inférieures.
