The invention relates to a sliding rail door-closing device (1) having an eccentrically positioned pinion (6) comprising a circular working curve. Said pinion intermeshes with a toothed rack (5) arranged on a piston (4). The aim of the invention is to design the working curve and the teeth (9) of the toothed rack (5) in such a way that they are adapted to a toothing of the pinion (6). In order to optimise the movement sequence of the piston (4) in the housing (2) of the sliding rail door-closing device (1), the invention further relates to an improved embodiment of the closing delay.

L'invention concerne un ferme-porte à glissière (1), qui comprend un pignon (6) excentré doté d'une ligne de roulement circulaire, ce pignon s'engrenant dans une crémaillère (5) disposée sur un piston (4). L'invention vise à concevoir la ligne de roulement et les dents (9) de la crémaillère (5) de sorte qu'elles soient adaptées à une denture du pignon (6). Afin d'optimiser le mouvement du piston (4) dans le carter (2) du ferme-porte à glissière (1), la présente invention porte également sur une conception améliorée de la temporisation de fermeture.
