Abstract

Vertical holding device for folding flat signs, supported by one of their edges on a horizontal base, particularly of signs provided with a rigid support provided with a crease or vertical middle line of folding, characterized by being constituted by a rectangular rectangular sheet provided of three vertical creases or fold lines that subdivide it symmetrically with respect to the central crevice in four quadrangular portions, of which the two extremes, narrower than the two intermediate ones, are adapted to be firmly fixed to the back face of the poster support so that the central vertical crease is located sensibly on the crease or vertical middle line of folding of the poster's support, while the intermediate portions are endowed, in turn, in their upper part and in their lower part, respectively, of separate creases or horizontal folding lines that determine corresponding folding flaps at right angles, all arranged so that when the poster is folded along its vertical middle line forming a dihedral angle and supported by the lower edges of the two sides of this dihedral angle on a horizontal surface, the intermediate portions of the said rectangular sheet also form a dihedral angle opposite to that of the poster and when folding inward the upper and lower fins of which respectively are provided, these fins come to be abutted against the rear face of the respective faces of the dihedral angle formed by the poster, keeping it in angular position.
