Abstract

LE DISPOSITIF COMPORTE UN MECANISME DE DECLENCHEMENT ASSERVI AU MOUVEMENT HORIZONTAL DU BRAS DE PICK-UP 12, POUR COMMANDER UN INTERRUPTEUR D'ARRET, PAR L'INTERMEDIAIRE D'UNE TIGE 18. LA DESCENTE DU BRAS 12 SUR LE DISQUE EST ASSUREE AUTOMATIQUEMENT, A VITESSE LENTE, CONTROLEE PAR DES MOYENS DE RALENTISSEMENT. CE MOUVEMENT EST COMMANDE PAR UNE MANETTE 36. DES MOYENS DE VERROUILLAGE, COMPORTANT, PAR EXEMPLE, UN LEVIER DE VERROUILLAGE 32 ASSERVI A LA MANETTE 36, BLOQUENT NORMALEMENT LE MECANISME DE DECLENCHEMENT CONSTITUE PAR LE LEVIER A TROIS BRANCHES 29, 31, 37, ASSOCIE EN ROTATION A UNE PLAQUE AUXILIAIRE 15. LA MANETTE 36 PERMET DE NEUTRALISER LES MOYENS DE VERROUILLAGE, POUR METTRE LE LEVIER DE DECLENCHEMENT A TROIS BRANCHES EN POSITION DE DECLENCHEMENT, SEULEMENT LORSQUE LE BRAS DE PICK-UP 12 EST ABAISSE SUR LE DISQUE. APPLICATION AUX DISPOSITIFS D'ARRET AUTOMATIQUE POUR TOURNE-DISQUES, POUR EN EVITER LE DECLENCHEMENT INVOLONTAIRE.THE DEVICE INCLUDES A RELEASE MECHANISM SLAVE TO THE HORIZONTAL MOVEMENT OF THE PICK-UP ARM 12, TO CONTROL A STOP SWITCH, THROUGH A ROD 18. THE LOWERING OF THE ARM 12 ON THE DISC IS ENSURED AUTOMATICALLY, A SLOW SPEED, CONTROLLED BY SLOWING MEANS. THIS MOVEMENT IS COMMANDED BY A HANDLE 36. LOCKING MEANS, INCLUDING, FOR EXAMPLE, A LOCKING LEVER 32 SLACED TO THE HANDLE 36, NORMALLY BLOCK THE RELEASE MECHANISM CONSTITUTED BY THE THREE-SPROCKED LEVER 29, 31, 37, IN ROTATION TO AN AUXILIARY PLATE 15. THE HANDLE 36 ALLOWS THE NEUTRALIZATION OF THE LOCKING MEANS, TO SET THE THREE-LEG RELEASE LEVER IN THE RELEASE POSITION, ONLY WHEN THE PICK-UP ARM 12 IS LOWERED ON THE DISC. APPLICATION TO AUTOMATIC SHUT-OFF DEVICES FOR RECORD PLAYERS, TO AVOID UNINTENTIONAL TRIGGERING.
