A drawer closing mechanism comprising a rack (20) fixed in position with respect to a furniture frame member and comprising a plurality of teeth (22) a drive gear (32) mounted to a drawer and comprising a plurality of teeth for engaging the teeth (22) on the rack (20), and a spring (34) with two ends, one end fixedly attached to said drive gear (32) and rotatable therewith and the opposite end fixed, wherein as the drawer is pulled open, the teeth on the drive gear (32) engage the teeth (22) on the rack (20) and rotate the drive gear (32), and as the drive gear (32) rotates, the spring (34) is wound and potential energy is stored in the tension therein. The drawer slide (24) is mounted to the furniture frame member, and the rack (20) is mounted to the drawer slide. In a preferred embodiment of the present invention, the spring (34) comprises a flat wire spring wound circumferentially about a central point in a spiral.
L'invention porte sur un mécanisme de fermeture de tiroirs comprenant: une crémaillère (20) à plusieurs dents (22) solidaire d'une partie du meuble, un pignon d'entraînement (32) monté sur le tiroir et dont les dents s'engrènent dans celles (22) de la crémaillère (20) et un ressort (34) dont une extrémité, fixée au pignon (32), tourne avec lui, et l'autre, est fixe. Lorsqu'on ouvre le tiroir, les dents de la crémaillère (20) s'engagent dans celles du pignon (32) et le font tourner, ce qui bande le ressort (34) où s'accumule de l'énergie potentielle. La glissière du tiroir est montée sur une partie du cadre du meuble, et la crémaillère (20) est montée sur la glissière. Dans l'exécution préférée le ressort est un ressort plat enroulé en spirale autour d'un point central.
