Drawer slide

Abstract

The invention concerns a drawer slide that has a swiveling double-armed lever around a pivot bearing and whose lever arms extend out from the pivot bearing and whose first lever arm, depending on the closed position, forms a positive/form-fitting connection between a linearly moving part and a cabinet-fixed part of the drawer slide, and whose second lever arm is connected to the draw-pull tension spring's first end and the second end of the draw-pull tension spring, distanced from it by under spring extension to a linearly moved or cabinet-fixed part of the drawer slide, is fastened. When the drawer is pushed in, the form-closure of the lever's first arm is turned out of a rest position over a dead center position in an automatic position, such that a further turn of the lever automatically shortens the pre-stressed spring on the second lever arm, so thus, pulling the drawer slide with the drawer into the cabinet opening. The advantage of the drawer slide with the invention-related self-closing mechanism is that after the ‘over-snapping’ of the lever's dead center position, which affects the spring action of the draw-pull tension spring on the turning lever in such a way that the torque increases on the lever with increasing pulling distance of the drawer. Thereby, the result is that the pulling force, which is directly proportional to the torque on the lever that affects the drawer, is small at the beginning of the self-closing cycle, but becomes greater with the increasing pulled distance so the retaining strength is the greatest when the drawer is closed completely.
