Problems solved by technology

[0004] The large number of different such accumulators necessary to assemble the automatic pull-in devices installed for different applications leads to relatively high inventory costs
Furthermore, in particular tension springs with a large spring constant can only be hung in the tensioning mechanism of the automatic retraction device when the automatic retraction device is installed, because otherwise the housing of the automatic retraction device would be damaged due to the high tension force of the tension spring. the threat of injury

Abstract

The invention relates to a self-retracting device (5) of a displaceable furniture part, comprising a housing (7, 8), at least one energy store (10) disposed on the housing and that can be tensioned when the displaceable furniture part is opened, a tensioning mechanism operationally connected to the at least one energy store (10) for pretensioning the at least one energy store against a driver (6) displaceably disposed on the housing, wherein the at least one energy store (10) is divided into at least two segments (11, 12, 13), wherein the functional length of the energy store (10) is adjustable by at least one fixing element (20, 21) releasably lockable to the housing (7, 8) and engaging between two segments (11, 12, 13) of the energy store (10). The invention further relates to a drawer slide.

Description

technical field [0001] The invention relates to an automatic retraction device for movable furniture parts and a pull-out guide with an automatic retraction device for drawers, sliding doors, furniture extensions or the like. Background technique [0002] Automatic pull-in devices and pull-out guides of the aforementioned type are known from the prior art in numerous embodiments. In this case, the automatic pull-in device basically consists of an energy store arranged on a housing that is fastened to rails fastened to the body of the furniture, wherein when a drawer, a furniture pull-out or the like is pulled from the closed position When pulling out, the accumulator is tensioned by the coupling of the automatic pull-in device to the trigger, wherein the trigger is fastened to a working rail which is fastened on its side to a drawer, furniture pull-out or similar and is movable on rails. [0003] In this type of automatic pull-in device, a special energy accumulator, most ...
