Abstract
A pullout guide for a furniture pullout part configured to be pulled out from a piece of furniture over a predefined pullout distance. The pullout guide includes a retraction device configured to retract the furniture pullout part at least over a portion of the predefined pullout distance. The retraction device includes a spring configuration having a first spring and a second spring connected in parallel with respect to each other. Each of the first and second springs includes a different spring characteristic curve than the other spring and/or each of the first and second springs includes a different force-distance characteristic acting in a pullout direction of the pullout guide.

A pullout guide for a furniture pullout part configured to be pulled out from a piece of furniture over a predefined pullout distance, the pullout guide comprising:
- a retraction device configured to retract the furniture pullout part at least over a portion of the predefined pullout distance;
- the retraction device including a spring configuration having a first coiled spring and a second torsion spring connected in parallel with respect to each other;
- wherein the second torsion spring acts as one of a tension and compression spring during a retraction of the furniture pullout part;
- wherein the second torsion spring is formed from a spring steel wire bent into an S-shape;
- wherein each of the first and second springs includes a different spring characteristic curve than the other spring;
- wherein each of the springs acts in an opening and a closing direction of the pullout guide, and closing direction forces of the two springs are additive;
- and
- wherein each of the different sprint characteristic curves includes a different force-distance characteristic acting in the pullout direction of the pullout guide.
A pullout guide for a furniture pullout part configured to be pulled out from a piece of furniture over a predefined pullout distance, the pullout guide comprising:
- a retraction device configured to retract the furniture pullout part at least over a portion of the predefined pullout distance;
- the retraction device including a spring configuration having a first coiled spring and a second torsion spring connected in parallel with respect to each other;
- wherein the second torsion spring acts as one of a tension and compression spring during a retraction of the furniture pullout part;
- wherein the retraction device further includes a slide and a pin and the pin acts on the torsion spring such that the torsion spring is pressed down by the pin in a maximum pullout position of the slide;
- wherein the torsion spring has two spaced-apart ends, the torsion spring is fixed on a housing via said spaced apart ends, said torsion spring has a bending area between the two ends, and the pin acts on said bending area;
- wherein each of the first and second springs includes a different spring characteristic curve than the other spring;
- wherein each of the springs acts in an opening and a closing direction of the pullout guide, and closing direction forces of the two springs are additive;
- and
- wherein each of the different sprint characteristic curves includes a different force-distance characteristic acting in the pullout direction of the pullout guide.
