Title:
ELECTROMECHANICAL IMPULSE GENERATOR COMPRISING A ROTATABLE CAM WHEEL IN THE FORM OF A TOOTHED RING
Document Type and Number:
WIPO Patent Application WO2003043040
Kind Code:
A3
Abstract:
The invention relates to a cam wheel (2) comprising circularly distributed toothed cams (9). Said cam wheel can be rotated over a pivotable trip cam (8) which slightly protrudes between the toothed cams. Said trip cam (8) is connected to laterally projecting contact arms (12) in a fixed manner, the free ends of said arms being at a distance over mating contacts (14) of a printed circuit board, in a central position. During the rotation of the cam wheel (2), the trip cam (8) is driven in the same direction and is pivoted until the contact arm (12) oriented in the rotational direction is positioned on the associated mating contact in such a way that it makes contact. When the rotation continues, the trip cam (8) goes back into its central starting position, under the action of a restoring spring (11, 26), the contact being broken. Said arrangement enables the structure of the impulse generator to be simplified and the functional reliability thereof to be increased.
