Title:
VARIABLE ACTUATOR WITH DISK-SHAPED MAGNET OR ANGLED MAGNET AND METAL ROD
Document Type and Number:
Japanese Patent JP2005198475
Kind Code:
A
Abstract:

To provide a variable actuator that is actuated by a magnet and a metal rod.

Some force is transmitted, and it throws up a flip-up plate (8) and rotates a projection (9). The tip of a cam (7) is moved from a lower position to an upper position perpendicularly thereabove. The tip of the cam is provided with a roller, and it can be moved by small force sufficient to push up a case (1) only a little. The case (1) is inclined, and the magnet (2) rolls down to the dead end. The tip of the metal rod (3) positioned nearby is moved upward, and its rear end pulls a cord (4). As a result, the actuation is transmitted. The magnet is returned to its original position by a spring (5) and a power spring (11). The tip of the metal rod is shifted downward by the self weight of the metal rod. The case (1) is also returned to its original position. With this construction, though apparently complicated, a wide range of power from small power to large power can be appropriately coped with. It is preferable that the metal rod should be separated or so constructed that magnetic force does not reach the metal rod behind its fulcrum.
