Embodiment Construction
[0029] As can be seen from FIG. 1 , the presence of vertical structural columns 2 within the field of view obscures areas of the field of view, creating so-called dead zones 4 . In particular, in the presence of a column 2 in one-piece form, a blind zone 4 is obtained if the cross-section 5 of the column 2 exceeds the distance 6 between the eyes 8' and 8" of the observer. Furthermore, the width of the blind zone 4 depends on In the cross-section 5 of the column 2, the distance 10 between the observer's eyes 8' and 8" and the column 2 and the projection 12 of the interpupillary distance in the direction of the column.
[0030] as from Figure 2 to Figure 8 As can be seen in , the device 50 according to the invention comprises a structural element 52 (for example, a vertical or inclined column) provided with a passage aperture (or diaphragm) 54 at which the application comprises two converging lenses Optical system 56 of 58, 62, with a diverging lens 60 inserted centrally betwe...

An installation (50) for improving the binocular visual field in the presence of a structural element (52) located at a distance from the observer equal to or greater than the observer's interpupillary distance, characterised in that said structural element (52) is provided with at least one through aperture (54) in which an optical system (56) is applied com prising two convergent lenses (58, 62), between which a divergent lens (60) is centrally interposed, the distance between each of said convergent lenses (58, 62) and said central divergent lens (60) being such as to render said optical system (56) of neutral afocal type.
Description
technical field [0001] The present invention relates to devices for improving the binocular field of view. Background technique [0002] In the presence of structural uprights and structural elements in general, binocular vision is partially covered and obscured by their bulk. In particular, the width of the covered optic portion is inversely proportional to the distance of the column from the eye. [0003] This disadvantage is particularly dangerous in the transportation industry in general and in the automotive industry in particular. In this regard, the vertical structural uprights of the vehicle partially obstruct side vision, potentially preventing the driver from noticing the presence of small-sized shapes such as pedestrians, cyclists, and motorcyclists, potentially causing accidents and / or risk of collision. [0004] Moreover, in recent decades, for safety reasons, primarily to mitigate the consequences of a motor vehicle tip-over, the vertical columns of the pass...
