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

[0025] figure 1 A graph showing the torque curve (torque M in Newton meters—Nm) over the opening angle (in degrees, α) of the flap 3 of the piece of furniture 1 . The characteristic curve A represents the (theoretical) curve of the torque to be applied by the actuating device 4 plotted against the angular position of the flap 3, wherein the flap 3 is accelerated neither in the opening direction nor in the closing direction by the actuating device 4 And thus maintain a balance. This characteristic curve A corresponds to the maximum adjustment of the torque in the opening direction, so that this can be set in heavy furniture flaps 3 . Starting from an opening angle of 0° of the flap 3 , the flap opens over an opening angle range, wherein the maximum value of the characteristic curve A is present 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 ...

Abstract

An actuating device (4) for moving a flap (3) of a piece of furniture (1), comprising: at least one actuating arm ( 5); the spring device (8) for applying force to the actuating arm (5); the transmission mechanism (10), which is used to transmit the force of the spring device (8) to the actuating arm (5) in the closing direction ) and is used to transmit the force of the spring device (8) to the actuating arm (5) in the opening direction after exceeding the dead center (T1, T2); the adjusting device (23), the actuating element of the actuating device (4) (19) Its position can be adjusted in or on the guide (21) by means of the adjustment device, wherein the actuating device (4) has the spring device (8), the rotation axis of the actuating arm (5) ( 13) Coupling device (18) for mutual coupling of the actuating element (19), wherein, by adjusting the actuating element (19) in or on the guide (21), not only the stop of the actuating arm (5) The position of the points (T1, T2) and the force of the spring means (8) acting on the actuating arm (5) in the opening direction can be variably adjusted so that the actuating arm (5) occurs at the dead point (T1 , T2) position that pivot angle can also become smaller as the force acting in the opening direction becomes larger.

Description

technical field [0001] The invention relates to an actuating device for moving a furniture flap. [0002] Furthermore, the invention relates to an arrangement system with a furniture flap and with an actuating device of the type to be described. Background technique [0003] Actuating devices of this type can have a rod mechanism as a dead center mechanism (DE 102 03 269 A1), wherein a spring device exerts a closing force on the actuating arm in the vicinity of the closed position and beyond the dead center position (connection of the rod) The hinge and the acting force vector are aligned in this dead center position) after which torque is applied to the actuating arm in the opening direction. Also known is a dead center mechanism (DE 10 2004 019 785 A1) with a control cam-roller configuration system in which the profile of the control cam is designed such that the actuating The torque on the arm changes after passing the dead center position. [0004] The force of the sp...
