BREWING DEVICE FOR CAPSULE WITH CLOSURE MECHANISM OF VARIABLE TRANSMISSION RATIO

摘要

PROBLEM TO BE SOLVED: To provide a device that requires relatively less manual closure force for a same lever arm or requires a smaller lever arm for a same force for closing a brewing component in a steady way about the capsule.SOLUTION: A brewing device for the brewing of a capsule containing beverage ingredients includes: a frame; a first and second capsule holding members for at least partially enclosing the capsule during brewing; wherein the first capsule holding member is mobile along the frame between an open and a closed position in relation to the second capsule holding member; and a closing mechanism to actuate the first holding member between the two positions and including an actuation member. The closing mechanism includes gear means able to transfer the torque provided by the actuation member into translational closure forces on the first holding member.
