Inverted pendulum oscillating controller impact switch with decreasing returning forces acting upon the pendulum as it pivots from its normal position
Abstract
Abstract A SWITCH MECHANISM IN WHICH A BIASING SPRING IS CONNECTED TO A MOVABLE MEMBER WHOSE INERTIA ACTUATES THE SWITCH THROUGH A CONNECTION WHOSE MECHANISM ADVANTAGE DECREASES AS THE MOVABLE MEMBER MOVES RELATIVE TO ITS SUPPORT TOWARD A SWITCH OPERATED POSITION AND IN WHICH THE TOTAL FORCES OPPOSING MOVEMENT TO THE SWITCH OPERATING POSITION DECREASE AS THE MOVABLE MEMBER APPROACHES A POSITION IN WHICH THE SWITCH IS OPERATED. THIS DECREASING MECHANICAL ADVANTAGE IS A RESULT OF CONNECTING A NONEXTENSIBLE MEANS TO THE MOVABLE MEMBER AT A POINT SPACED FROM THE PLANAR SURFACE AND OUTWARDLY OF THE CENTER OF GRAVITY OF THE MOVABLE MEMBER. THE MOVABLE MEMBER MAY MOVE IN A PLURALITY OF DIRECTIONS.
