JP2005198475A - Variable actuator with disk-shaped magnet or angled magnet and metal rod - Google Patents

Abstract

<P>PROBLEM TO BE SOLVED: To provide a variable actuator that is actuated by a magnet and a metal rod. <P>SOLUTION: 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. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

Detailed Description of the Invention

[Technical field to which the invention belongs]
The present invention is widely used for industrial operation devices such as switch operation, door locking, and space operation.

[Conventional technology]
Conventional actuators can do most of the electrical work, but some are expensive, too big, and can't be used for anything, and are kept to a minimum. In some cases, the structure cannot be used.

[Problems to be Solved by the Invention]
Therefore, it is not good at the direct operation corresponding to the operation that always bends, and the design is difficult. It was also not good at working in response to impact force.

[Embodiment of the Invention]
[Example 1]
In FIG. 1, regardless of whether the force is large or small, any impact force may be used. Then, the jump plate of (8) goes up. Rotate the thrust of (9) that rotates idly by reverse rotation, stir the shaft, and make the tip of the (7) cam located below to the vertical direction upward. This rotates only at a constant interval, rotates idly, and has a structure in which the cam tip automatically returns downward with the shape memory spring of (11). Then, the case of (1) goes up, and the magnet of (2) inside rolls down to the lower right end. Then, the metal rod (3), which had its head lowered, raised the head (front end) by the magnet's attractive force, applied the fulcrum (12), lowered the rear end, and pulled the string (4), Various operations such as changing the display such as switch contacts and door locking. The shape memory spring (5) returns the case (1) to its original position and the magnet to its original position.
Then, as shown in FIG. 2, the metal rod hangs downward with the weight of its own head, and the rear end portion returns to the original upper position.

〔The invention's effect〕
It can respond easily to the magnitude of the force and impact, and by changing the setting, it has become possible to easily react only to the action of a certain range of force. In terms of the approach of magnets and metal rods, it has become possible to consider various uses such as working switches in outer space.

Claims (1)

A disk-shaped or magnet that may have a square periphery is capped with a metal to be adsorbed, covered with a metal that adsorbs one side, and adsorbed to the adsorbing metal for a certain period of time. As a result, the magnet has a magnetic force direction, polarity change, unevenness, and a magnet with similar effects. By approaching perpendicularly (may be slightly different) to such a magnet surface, the stick-like metal that is hollow is repelled from the center and pulled to the outer periphery. The normal one that is not hollow is repelled from the outer periphery and pulled to the center (rarely, the opposite is also possible). Actuator that is more powerful and industrially durable
