Th hinge screw is then inserted, the trigger 16 is release whereupon the spring 16b returns the trigger in a clockwis direction to its normal release position, moving the grippe pads 33 rearwardly in the direction of divergence of th inclined vertical sides 30b and retracting the gripper pad 33 from each other to release the temple piece, enabling th spectacles to be removed from the tool.

Abstract

L'outil à main décrit (10), qui est destiné à être utilisé avec des lunettes du type à charnières à ressorts, sert à faciliter le démontage et le remplacement des vis des branches qui relient de façon pivotante les lames de charnières ajourées d'éléments de charnières associés installés sur la monture des verres et les extrémités avant des branches. Un tel outil comprend un élément de corps d'outil en forme de pistolet (12) comportant une partie profilée en U à glissière (14) et un bras de support rigide s'étendant vers l'avant (19), un montant allongé (22), une sous-unité (21) soutenue réglable sur le montant et pourvue d'un coussinet (26) contre lequel vient se plaquer le verre et d'un bras (28) retenant le verre et placé espacé de façon superposée par rapport aux parties superficielles du coussinet en contact avec le verre, ainsi qu'une sous-unité de support des branches comprenant une paire de coussinets (33) placés face à face servant à pincer les branches et mutuellement espacés de façon à définir entre eux un évidement destiné à recevoir les branches et s'ouvrant vers le haut. Un mécanisme (16) de réglage des coussinets est prévu pour éloigner et rapprocher les coussinets pinceurs l'un de l'autre, de façon à libérer et à pincer une branche placée entre eux. Un tel agencement facilite la manipulation avec une main de l'outil par un opérateur, tout en empêchant de façon réversible le mouvement relatif de la monture des lunettes et des branches lorsque ceux-ci sont placés dans leurs sous-unités de support respectives.
