VENETIAN BLINDS OF SIX INTERCHANGEABLE IMAGES FOR THE EXHIBITION OF PUBLIC ANNOUNCEMENTS AND GRAPHIC ARTS.

摘要

The present invention refers to a system of presentation of public announcements and graphic arts which consist of a venetian blind of six interchangeable images wherein rectangular sheets participate of any rigid or flexible material, mobile sheets perpendicularly inserted to the fixed sheets which have half the width of the mobile sheets and which are joined by its sides to the middle part of the mobile sheets by means of hinges of any material. The mobile sheet ends are joined by means of traction elements which coordinate the movement of the mobile sheets to 90 degree towards one side or towards the other. The images are placed in all the visible rectangles of each of the sheets in front of or behind the blind. By turning 90 degree towards one side, the mobile sheets cover the fixed sheets, also covering the images placed in them in front of as much as behind the blinds. If the turn of the fixed sheets together with its images remain exposed the images placed on the visible rectangles in the front and back part of the blind offer an on-looker six different interchangeable images, three in front and three behind.
