  • the two blades each feature sharpened leading edges that move into each other as the back sides of the blades are squeezed.
  • Scissor blades of the prior art feature planar inside surfaces that smoothly slide upon one another during use. While the smooth planar inside surfaces of the blades and conducive to precise cutting, the smooth inside surfaces are easily fouled with debris when cutting organic matter.

Abstract

Cette invention concerne divers modes de réalisation de ciseaux présentant des vides ou passages en forme de canal définis dans les surfaces intérieures des lames ou sections d'axe de ciseaux. Les vides ou passages en forme de canal permettent aux corps étrangers d'être expulsés automatiquement par le déplacement des lames de ciseaux. Les lames ou axes selon l'invention sont connectés de manière pivotante par un ensemble de liaison novateur qui expulse les corps étrangers pendant l'utilisation normale des ciseaux. Les modes de réalisation divulgués concernent des ciseaux comprenant : une paire de lames (1A, 1B) se chevauchant mutuellement; et un axe (3) inséré à travers un trou de support d'axe (2) dans les lames (1A, 1B) et présentant une pointe (4) qui est emboutie pour permettre aux lames (1A, 1B) de pivoter dans un état de butée, un passage communiquant avec l'extérieur pour permettre l'entrée et la sortie d'eau, etc. étant formée entre les faces de butée (5) des deux lames (1A, 1B) et entre l'axe (3) et les trous de support d'axe (2).
