Patent ID: 8590107

Claim:
An actuating device comprising: a housing; a pivotally mounted actuating arm for moving a furniture flap; a spring device for acting on said actuating arm; and an assembly securing device for securing said actuating arm when no furniture flap has been fitted to said actuating arm to thereby prevent accidental opening or deflection of said actuating arm, said assembly securing device including: a rotatable shaft connected to said actuating arm; a braking device including a portion connected to said shaft so as to rotate about an axis of said shaft, said braking device being configured to stop a rotation of said shaft and a pivoting movement of said actuating arm when a predetermined pivotal speed of said actuating arm is exceeded; a step-up transmission including a gear transmission comprising a pinion on said shaft and a tooth arrangement on said housing, said pinion having a different size than said tooth arrangement and being arranged to mesh with said tooth arrangement, said step-up transmission being configured to convert a pivotal speed of said actuating arm at least over a region of a pivot travel of said actuating arm in an opening direction to a greater rotary speed of said shaft based on a predetermined transmission ratio, said braking device being configured to actuate when said greater rotary speed of said shaft exceeds a predetermined rotary speed so as to stop the rotation of said shaft and the pivoting movement of said actuating arm.
