  • the self-closing device of the slide may have malfunction under certain unexpected situations.
  • the movable member 165 may be unintentionally moved to its introduction position (See FIGS. 3 and 14) under any unexpected situations, for example, if any obstacles are jammed between the slide and the self-closing device.
  • the self-closing device according to the present invention is capable of returning its normal operating state despite the above abnormal situation.
  • the drawer is not allowed to be automatically moved to its introduction position even if the drawer is pushed.
  • the detachable-coupling latch 25 of the movable rail 20 meets with the oblique-profiled surface 149 extended from the first holding portion 142 of the latch holding structure 141, thereby applying a force onto the oblique-profiled surface 149.
  • the rotational movement member 140 is forcibly pushed in a direction designated by the arrow A.
  • the first protrusion 144 of the rotational movement member 140 pushes the flexible bar 129, formed in the ceiling surface 127 of the movable member positioning portion 120 of the housing 110, toward the direction of the arrow A. Since the first space 130 and the second space 131 are formed at opposite sides of the flexible bar 129, the flexible bar 129 is elastically bent into the second space 131. Simultaneously, the detachable-coupling latch 25 passes over the oblique-profiled surface 149, and is again be caught by the latch holding structure 141. In this way, the self- closing device can restore its normal operating state for preparing the pulling-out of the drawer.

Abstract

L'invention concerne un dispositif de fermeture automatique à utiliser dans une fixation inférieure de type glissière. Le dispositif de fermeture automatique comprend un boîtier en forme de boîte comportant un corps et un moyen de fixation aux deux extrémités, un élément mobile pourvu d'un élément à mobilité rectiligne et un élément à mobilité rotative, et un ressort élastique présentant des parties de diamètre réduit réalisées dans un corps de ressort aux emplacements proches des deux extrémités du corps ressort. Si besoin, le dispositif de fermeture automatique comprend également un amortisseur composé d'un vérin présentant une partie d'extension frontale et d'une tige de piston qui émerge d'un côté du vérin. Le dispositif de fermeture automatique permet le déplacement automatique et efficace d'un tiroir pour l'amener dans sa position entièrement fermé et ce, sans article de meuble.
