Bar grating with removable locked bars

摘要

The grille has longitudinal bars (2, 3) each comprising connection slugs connected with coupling slugs of transversal bars (4, 5). Each connection slug has form and length adapted for being received in transversal cut (142) of respective coupling slugs. Connection segments of respective connection slugs are limited by shoulders (127E, 126E) axially arranged opposite to stop surfaces (148B, 149B) of the corresponding coupling slug.
