Device for holding a paper sheet

Abstract

Device intended to maintain a paper sheet close to the vertical in order to facilitate the viewing thereof, characterized in that it is comprised of first holding means ( 1 ) and second holding means ( 2 ) which cooperate with the first holding means ( 1 ) so as to confer progressively to the sheet, as it is introduced between the first and the second holding means, an initial curvature which rigidifies the sheet.

  wherein the first and second holding elements are arranged such that
 (a), the protruding section and the bearing zones overlap each other partially to enable a curvature to be conferred gradually upon the paper sheet to be inserted, wherein the protruding section and the bearing zones are tilted backwards with the protruding section tilted less than the bearing zones, 
 (b) two lines of force are allowed to be created, on the paper sheet to be inserted, towards the upper angles of the paper sheet in order to rigidify the paper sheet, and 
 (c) the device allows the paper sheet to be inserted to obtain a backward tilt ranging from 45° to 85°; and the first holding element is mounted on an articulation interconnected to an actuating body fitted with a compressible element in position against the second holding element, wherein actuation of the actuating body enables the first holding element to be spread apart from the second holding element in order to facilitate placement of the paper sheet to be inserted.
