ABSTRACT:
A remote control driving mechanism works in the manner of an OR-gate for performing a mechanical switching operation by one of two or more operating control input levers at a time. For this purpose an operable member (2) to be driven is connected to a cam follower (17) which cooperates with two or more cam disks (9, 10) each connected to a respective operating lever (4, 5) through a corresponding push-pull cable (6, 7). Each cam disk (9, 10) has a cam track with a force transmitting section (13, 14) and with a guide section (15, 16) so arranged and configured that the cam follower (17) engages a force transmitting cam track section in one cam disk while engaging a guide cam track section in the other cam disk and vice versa. The sections of each cam track form a U- or V-configuration with a dead point (DP) between the cam track sections. The cam follower (17) is freely movable in the guide track sections, whereby the respective cam disk cannot be operated by its corresponding push-pull cable.
