Problems solved by technology

However, such an adjustment also affects the closing force of the actuating arm in the case of an actuating device with a dead center mechanism, which leads to the fact that the furniture flap is held closed with a correspondingly high closing force even when the torque of the actuating arm in the opening direction is high. in position

Embodiment Construction

[0029] figure 1 A graph showing the torque curve (torque M in Newton meters - Nm) in relation to the opening angle (in degrees, α) of the flap 3 of the furniture 1 . The characteristic curve A represents the (theoretical) curve of the torque to be exerted by the actuating device 4 with respect to the angular position of the flip 3 , wherein the flip 3 is neither accelerated in the opening direction nor in the closing direction by the actuating device 4 and thus maintain balance. This characteristic curve A corresponds to the maximum adjustment of the torque in the opening direction, so this can be set in heavy furniture flaps 3 . Starting from an opening angle of 0° of the flap 3 , the flap opens over a range of opening angles, wherein the maximum value of the characteristic curve A occurs at an opening angle of the flap 3 of approximately 90°. That is, when the opening angle of the flip 3 is 90°, the actuating device 4 must provide the maximum torque so that the flip 3 is a...

Abstract

The invention relates to an actuating drive (4) for moving a flap (3) of an item of furniture (1), comprising: at least one actuating arm (5) which is supported so as to be pivotable about an axis of rotation {13} for moving the flap (3), a spring device (8) for application of force to the actuating arm (5), a transmission mechanism (10) for transmitting a force from the spring device (8) onto the actuating arm (5) in the closing direction and, after exceeding a dead centre (T1, T2), for transmitting a force from the spring device {8} onto the actuating arm (5) in the opening direction, an adjusting device (23), by which an actuator (19) of the actuating drive (4) is adjustable in its position in or on a guide (21), wherein the actuating drive (4) has a coupling device (18) which couples the spring device (8), the axis of rotation (13) of the actuating arm (5), and the actuator (19) to one another, wherein by adjustment of the actuator (19) in or on the guide (21) both the location of the dead centre (T1, T2) of the actuating arm (5) and the force of the spring device (8) acting in the opening direction on the actuating arm (5) can be set variably such that, in the event of an increase in the force acting in the opening direction, the pivot angle of the actuating arm (5) at which the dead centre (T1, T2) is located can be reduced.

Description

technical field [0001] The present invention relates to an actuating device for moving a furniture flip, the actuating device comprising: [0002] - at least one pivotably supported actuating arm for moving the flip, [0003] - spring means for applying force to the actuating arm, [0004] - a transmission mechanism for transmitting the force of the spring means to the actuating arm in the closing direction and for transmitting the force of the spring means to the actuating arm in the opening direction after passing the dead point, [0005] - an adjustment device, by means of which the actuating element of the actuating device can adjust its position in or on the guide. [0006] Furthermore, the invention relates to a configuration system with a furniture flap and with an actuating device of the type to be described. Background technique [0007] An actuating device of this type can have a lever mechanism as a dead center mechanism (DE 102 03 269 A1), wherein a spring dev...
