摘要

Improved slide frame, essentially characterized by being constituted by a single-piece elementary box of orthohedral and flattened configuration, of very small thickness with respect to length and width, with an internal space of rectangular shape limited by the narrow lateral faces constituting the the edges, one of which presents on its entire surface a longitudinal central groove, extended parallel to the adjacent side faces, allowing the introduction of the frame and its housing inside the openings of size corresponding to the picture of the frame and, inside, of a pair of lugs of reduced size in order to retain the frame, avoiding its accidental displacement.
