CA 2581742

A net guide for a wire screen, made to absorb an impact by causing connections of many guide pieces of a net guide formed by the connections of the guide pieces to have a stretchability. A net guide going in and out from a lower end of a movable frame in compliance with an opening/closing of a net to thereby guide a lower end of the net is constituted by connecting, by a wire, many guide pieces formed approximately like a U-letter by a bottom part and a standing wall part. The wire is inserted through through-holes of the guide pieces, and the guide pieces under a connected state are pressed by a coil spring giving a tension to the wire.

Le guide-filet pour porte-écran décrit est formé en connectant un certain nombre de pièces de guidage entre elles de manière à étendre la connexion des pièces de guidage et à absorber ainsi les chocs. Un guide-filet (12) adapté pour entrer et sortir de l~extrémité inférieure d~une boîte mobile (5) en réponse à l~ouverture/fermeture d~un filet (4) pour guider l~extrémité inférieure du filet (4) est composé en reliant un certain nombre de pièces de guidage (14), formées chacune d~une partie de fond (14a) et d~une paroi verticale (14b) prenant pour l~essentiel une forme en U, à l~aide d~un câble (15). Le câble (15) est inséré dans les trous traversants (14c) dans les pièces de guidage (14). Les pièces de guidage (14), qui sont à l~état connecté, sont comprimées par un ressort à enroulement (17) transmettant la tension au câble (15).
