The present invention relates to a locking structure of safety glasses for a pair of side shields that shield the eyes from being damaged by scattered metallic pieces that are generated in a workshop. The present invention provides a locking structure of safety glasses for a pair of side shields, where the safety glasses include a pair of lenses, a pair of rims, a bar and bridge, a pair of arms and a pair of side shields and each of the side shields includes a guide groove and a pair of shield wings, comprising a pair of fitting projections that are formed in the guide groove, are projected upward and bent toward each other, and serve to allow the side shields to slide along the arm while preventing the side shields from being separated from the arm, and a pair of slide preventing means that are respectively provided on predetermined positions of the arms so as to prevent the side shields from sliding along the arms by engaging the fitting projections respectively.

La présente invention concerne une structure de verrouillage pour écrans latéraux de lunettes de protection, lesquels écrans protègent les yeux des éclats de pièces métalliques produits dans un atelier. La présente invention concerne une structure de verrouillage pour écrans latéraux de lunettes de sécurité, lesdites lunettes de sécurité comprenant une paire de verres, une monture, une barre et un pont, une paire de branches et une paire d'écrans latéraux. Chacun de ces écrans latéraux comporte une rainure de guidage, une paire de coques de protection, et une paire d'éléments saillants de fixation formés dans la rainure de guidage, orientés vers le haut et courbés l'un vers l'autre, qui servent à permettre le coulissement des écrans latéraux le long de la branche tout en empêchant que lesdits écrans latéraux ne se séparent de la branche. Les lunettes selon l'invention comprennent également une paire de moyens anti-coulissement placés respectivement en des points prédéterminés des branches, de manière à empêcher que les écrans latéraux ne coulissent le long des branches du fait de leur contact avec chacun des éléments saillants de fixation.
