Abstract:
An office accessory hereafter called â€œsheet folding deviceâ€  (1), which is designed and adapted to facilitate accurate and rapid folding of sheets of paper of standard height and length in order to insert them into commercial envelopes of corresponding dimensions, said sheet folding device comprising:a planar base (3) made from a rigid material, said base having a width (L) substantially equal to the standard width of the sheets to be folded and a height (H) at least equal to two thirds of the standard height of said sheets, and having a lower edge (11) and two lateral edges (13,15); at least one limit stop (17) integral to the base, said at least one limit stop(s) extending from the level of the lower edge (11) of the base and projecting slightly over this lower edge in order to serve as a support to the lower edges of the sheets to be folded; and folding guides (21, 23) integral to the base (3) , said folding guides being shaped and placed in such a way as to permit to preform folding lines in order to subsequently fold said sheets in two parts or more for inserting them into commercial envelopes, characterized in that: said folding guides are at least three in number, the first one (21) of said guides extending transversely along the entire width of the base (3) at a distance from the lower edge substantially equal to one third of the standard height of said sheets, the second one (23) of said guides extending transversely along the entire width of the base at a distance from the lower edge substantially equal to two thirds of the standard height of said sheets, the third one of said guides (25) extending transversely along the entire width of the base at a distance from the lower edge corresponding substantially to half of the standard height of the sheets to be folded; and said folding guides (21,23,25) have a triangular cross-section to allow a user having positioned one or several sheets of paper to be folded on the base (3) and against the limit stop(s) (17), to press with his/her fingers on the sheet(s) along the guides in order to define and manually preform said required folding lines for folding purpose.
