Abstract

A piece of furniture has an actuating arrangement for a flap of the piece of furniture. An actuating arm arrangement includes a lever arrangement for moving the flap and a main spring that acts in the closing direction (SR) to hold the flap closed. The piece of furniture also has an ejecting device for ejecting the flap in the opening direction (OR) by overpressing the flap in the closing direction (SR). At least one support spring acts in the opening direction (OR) and is separate from the ejecting device, and supports the ejecting motion of the ejecting device. At least in an overpressed closed position (US), the spring forces (A, U) are together greater than the closing force (Z) which acts on the flap and which is provided by the main spring acting in the closing direction (SR).

Claims

1. An adjusting arm arrangement kit comprising:

a lever arrangement to be connected to a flap, said lever arrangement including a first lever and a second lever;

a main spring for acting on said lever arrangement so as to thereby act on the flap via said lever arrangement in a closing direction of the flap;

a damping device configured to apply a damping force to the flap in a closing direction of the flap in a first configuration of said adjusting arm arrangement kit; and

an ejection support device integrated into said lever arrangement and configured to act on said lever arrangement so as to thereby act on the flap in an opening direction of the flap in a second configuration of said adjusting arm arrangement kit, said ejection support device including;

a support spring mounted on said first lever of said lever arrangement and acting on said second lever of said lever arrangement; and

a pusher loaded via said support spring and configured to act on said lever arrangement so as to thereby act on the flap in the opening direction of the flap, said pusher configured to lie against said second lever of said lever arrangement, only a spring force of said support spring acting on said pusher;

wherein said adjusting arm arrangement kit is convertible from said first configuration of said adjusting arm arrangement kit to said second configuration of said adjusting arm arrangement kit by replacing said damping device with said ejection support device;

wherein said main spring and said support spring are configured so that, in a range of relative opening angles between a furniture body and the flap of 0°

to 10°

, a spring force of said support spring acting on said furniture flap in the opening direction of said furniture flap is less than the spring force of said main spring acting on said furniture flap in the closing direction of said furniture flap; and

wherein said main spring and said support spring are configured so that, in a range of relative opening angles between said furniture body and said furniture flap of 20°

to 50°

, the spring force of said support spring acting on said furniture flap in the opening direction of said furniture flap is greater than the spring force of said main spring acting on said furniture flap in the closing direction of said furniture flap.

2. The adjusting arm arrangement kit of claim 1, wherein said ejection support device further includes a housing accommodating said support spring, said pusher and said support spring being guided by said housing.

3. The adjusting arm arrangement kit of claim 1, wherein said damping device of said first type and said ejection-support device of the second type have substantially identical overall dimensions.

4. The adjusting arm arrangement kit of claim 1, wherein said support spring is a coil spring.
