As shown in FIGS. 1 to 4, a thrust generating mechanism (thrust generating device) 1 according to the first embodiment can move on a plane G (see FIGS. 3 and 4) such as the ground or floor, and can move on a plate. A moving part 3 to which a plate-shaped first magnet (first magnet) 9 is attached, and a linear first magnet part (one side It has a magnet portion) 5 and a second magnet portion (the other side magnet portion) 7 . Although there is one moving part 3 in this embodiment, in FIG. Two moving parts 3 are shown.

The moving part 3 includes a first plate-shaped magnet 9 (see FIG. 2) which is a permanent magnet, a non-magnetic case 11 (see FIG. 1) made of resin or the like that covers the first plate-shaped magnet 9, The case 11 has four wheels 13 (see FIG. 4(a)) provided on the front and rear of the lower portion of both side surfaces of the case 11 and placed on the plane G, and the forward direction indicated by the arrow A (see FIG. 4). 1, leftward in FIGS. 2 and 4). 2, the illustration of the case 11 and the wheel 13 in the moving part 3 is omitted for convenience of explanation (in other words, only the plate-like first magnet 9 is illustrated), and in FIGS. 3 and 4, the moving part 3 is omitted (in other words, only the plate-like first magnet 9 and the wheel 13 are shown).

As shown in FIG. 2(a), the lower left side (one side) 9a of the plate-like first magnet 9 as viewed in FIG. 2(a) has an N magnetic pole. The upper right side surface (the other side) 9b of 9 as viewed in FIG. 2(a) has an S pole magnetic pole. In the state where the moving part 3 is placed on the plane G, the left side 9a and the right side 9b of the plate-like first magnet 9 are vertical planes perpendicular to the plane G (see FIG. 3).

Further, as shown in FIG. 4(b), in the state where the moving part 3 is placed on the plane G, the forward direction indicated by the arrow A and the height direction of the first plate-shaped magnet 9 (in FIG. 4(b) When viewed from a direction perpendicular to the vertical direction (the direction penetrating the paper surface in FIG. 4B, this direction is hereinafter simply referred to as the “vertical direction”), A first centerline (moving-side centerline) C1 passing through the center is parallel to the plane G.

Here, regarding the plate-like first magnet 9 shown in FIGS. 2 to 4, the N pole is a white portion and the S pole is a black portion. This also applies to the second plate-shaped magnet 15 and the third plate-shaped magnet 17, which will be described later, and also to FIG. 6, which will be described later. In this embodiment, the white portion is the N pole and the black portion is the S pole, but it goes without saying that the white portion may be the S pole and the black portion may be the N pole.

The moving direction of the moving part 3 of this embodiment is regulated by each wheel 13 to either the forward direction (first direction) indicated by the arrow A or the rearward direction opposite to the first direction. In other words, it can be said that the case 11 and the four front, rear, left, and right wheels 13 constitute a moving direction restricting portion that restricts the moving direction of the moving portion 3 in the front-rear direction. It should be noted that the moving direction restricting portion is not limited to the case 11 and the wheel 13 and is not shown, but is formed, for example, on the grooved rail portion formed on the plane G and the bottom surface of the plate-like first magnet 9. The moving direction regulating portion is formed by the convex portion that is inserted into the rail portion of the groove, or the groove into which the bottom portion of the case 11 of the moving portion 3 can be inserted on the plane G is used as the moving direction regulating portion. It is possible to appropriately adopt an aspect such as In addition, the movement direction restricting portion may restrict movement not only in the front-rear direction but also in the forward direction. Any device may be used as long as it can regulate the moving direction of the moving portion 3 that moves by magnetic force (repulsive force).

As shown in FIG. 2C, the linear first magnet portion 5 is configured by arranging a plurality of plate-like second magnets (second magnets) 15, which are plate-like permanent magnets, along the front-rear direction. The plurality of plate-shaped second magnets 15 have the same shape. Specifically, the linear first magnet portion 5 is arranged on the upper half of the rear surface of the second plate-shaped magnet 15 on the front side in the second plate-shaped magnet 15 adjacent to the front and back. After the lower halves of the front surfaces of the plate-shaped second magnets 15 are successively fixed so as to be connected to each other by adhesion or welding, the periphery of these plate-shaped second magnets 15 is covered with a non-magnetic case (not shown). In addition, in FIG.2(c), a part of all the plate-shaped 2nd magnets 15 which comprise the linear 1st magnet part 5 are fracture|ruptured and shown for convenience of explanation.

The lower left side 15a of each plate-shaped second magnet 15 as seen in FIG. 2(a) has an S pole, and the upper right side (the other side) 15b as seen in FIG. has the same north magnetic pole as the left side (one side) 9 a of the plate-like first magnet 9 . That is, as shown in FIG. 3, the right side surface (one side facing surface) 15b of each of the plate-shaped second magnets 15 extends between the linear first magnet portion 5 and the linear second magnet portion 7 in the forward direction. It can face the left side (one side) 9a of the plate-like first magnet 9 of the moving part 3 moving toward the right side, and has the same polarity as the left side 9a. Therefore, a repulsive force CL acts between the left side surface 9 a of the first plate-like magnet 9 and the right side surface 15 b of the second plate-like magnet 15 . In addition, when the linear first magnet portion 5 is placed on the plane G, the left side 15a and the right side 15b of each of the plate-like second magnets 15 are perpendicular to the plane G. ing.

As shown in FIGS. 4(b) and 4(c), the lower end of the rear end of each plate-shaped second magnet 15 (for example, the lower right corner as viewed in FIGS. 4(b) and 4(c)) is While in contact with the plane G, the lower ends of the tip portions of the second plate-shaped magnets 15 (lower left corners in FIGS. 4(b) and 4(c)) are floating from the plane G. there is In other words, each of the second plate-shaped magnets 15 is tilted forward and upward so that the tilt angle between the bottom surface of the second plate-shaped magnet 15 and the plane G is a predetermined angle (acute angle). In addition, the inclination angles of the respective plate-shaped second magnets 15 are the same. Therefore, the second center line (non-moving side first center line) C2 passing through the centers of the plate-shaped second magnets 15 in the height direction is , intersects the first center line C1 of the plate-like first magnet 9 at a predetermined angle when viewed from the vertical direction.

As shown in FIG. 2(b), the linear second magnet portion 7 has a plurality of plate-like third magnets 17, which are plate-like permanent magnets, in the same manner as the above-described first linear magnet portion 5. The plurality of plate-like third magnets 17 have the same shape as each other. Specifically, the linear second magnet portion 7 is arranged on the upper half of the rear surface of the front third plate magnet 17 in the third plate magnet 17 adjacent to the front and rear. After the lower halves of the front surfaces of the third magnets 15 are successively fixed so as to be connected to each other by adhesion or welding, the periphery of the third magnets 15 is covered with a non-magnetic case (not shown). In addition, in FIG. 2(b), as in FIG. 2(c), for convenience of explanation, a part of all the plate-like third magnets 17 constituting the linear second magnet portion 7 is shown. .

The lower left side (other side facing surface) 17a of each of the plate-like third magnets 17 in FIG. 2A has the same S pole as the right side (the other side) 9b of the plate-like first magnet 9. , and the upper right side surface 17b as viewed in FIG. 2(a) has an N magnetic pole. That is, the left side surface (other side facing surface) 17a of each of the plate-shaped third magnets 17 extends forward between the linear first magnet portion 5 and the linear second magnet portion 7 as shown in FIG. It can face the right side (the other side) 9b of the plate-like first magnet 9 of the moving part 3 moving toward the right side, and has the same polarity as the right side 9b. Therefore, a repulsive force CR acts between the right side surface 9b of the first plate-like magnet 9 and the left side surface 17a of the third plate-like magnet 17. As shown in FIG. Further, in a state in which the linear second magnet portion 7 is placed on the plane G, the left side surface 17a and the right side surface 17b of each of the plate-like third magnets 17 are vertical surfaces perpendicular to the plane G. ing.

As shown in FIGS. 4(b) and 4(c), the lower end of the rear end of each plate-shaped third magnet 17 (for example, the lower right corner as viewed in FIGS. 3(b) and 3(c)) is While in contact with the plane G, the tip of each third plate-shaped magnet 17 (the left end as viewed in FIGS. 3(b) and 3(c)) is floating from the plane G. As shown in FIG. In other words, each of the third plate-like magnets 17 has the same angle of inclination between the bottom surface of the third plate-like magnet 17 and the plane G as the angle of inclination between the second plate-like magnet 15 and the plane G. The plate-like third magnets 17 are inclined forward and upward at a predetermined angle, and the inclination angles of the plate-like third magnets 17 are the same. Therefore, when the linear second magnet portion 7 is placed on the plane G, the third center line (second center line on the non-moving side) C3 passing through the centers of the plate-shaped third magnets 17 in the height direction is , is parallel to the second center line C2 when viewed from the vertical direction, and intersects the first center line C1 of the plate-like first magnet 9 at a predetermined angle (acute angle).

As shown in FIG. 1, the linear first magnet portion 5 and the linear second magnet portion 7 are formed to have the same length. The linear first magnet portion 5 and the linear second magnet portion 7 are arranged parallel to each other on the plane G with a predetermined gap therebetween so as to face each other. In this state, the first linear magnet portion 5 and the second linear magnet portion 7 are arranged such that the tip of the second linear magnet portion 7 is positioned further than the tip of the first linear magnet portion 5 when viewed from the vertical direction. , the length of the plate-shaped third magnet 17 inclined at a predetermined angle in the front-rear direction (hereinafter simply referred to as "the front-rear length of the magnet"). That is, the first linear magnet portion 5 and the second linear magnet portion 7 are arranged such that the second plate-like magnet 15 and the third plate-like magnet 17 are separated from each other by the longitudinal length of the magnets when viewed in the vertical direction. It is positioned with a half forward and backward shift (see FIG. 1).

Specifically, in FIG. 1, among the (plural) plate-shaped second magnets 15 that constitute the linear first magnet portion 5, the plate-shaped second magnet 15 located on the most front side (the most in FIG. Among the second plate-shaped magnet 15 on the left side and the third plate-shaped magnet 17 constituting the linear second magnet portion 7, the third plate-shaped magnet 17 located on the frontmost side (the leftmost in FIG. 1) As can be seen from the plate-like third magnet 17), the linear first magnet portion 5 and the linear second linear magnet portion 7 are located at the lower tip of the most front side plate-like second magnet 15. is positioned at the center of the third plate-shaped magnet 17 on the frontmost side. The first linear magnet portion 5 and the second linear magnet portion 7 may be arranged if the second plate-like magnet 15 and the third plate-like magnet 17 are displaced from each other in the vertical direction. Well (in other words, it is sufficient if the second plate-shaped magnet 15 and the third plate-shaped magnet 17 do not overlap when viewed from the vertical direction). can be set as appropriate. Further, in the present embodiment, the linear second magnet portion 7 is shifted forward from the linear first magnet portion 5, but instead of this, the one-side magnet 5 is shifted toward the other-side magnet 7. Needless to say, it may be shifted further forward.

In the present embodiment, since each of the second plate-shaped magnets 15 and each of the third magnets 7 has the same shape, the second plate-shaped magnets 15 of the linear first magnet portion 5 and this The plate-like third magnet 17 of the linear second magnet portion 7 facing the plate-like second magnet 15 has the following positional relationship.

That is, taking the second plate-shaped magnet 15 on the frontmost side of the linear first magnet portion 5 as an example, the front half of the second plate-shaped magnet 15 (the left half in FIG. 1) is The rear half portion (the right half portion in FIG. 1) of the third plate-shaped magnet 17 on the frontmost side of the linear second magnet portion 7 faces the rear half portion of the second plate-shaped magnet 15. It faces the front half portion of the third plate-shaped magnet 17 located behind the third plate-shaped magnet 17 on the front side (in FIG. 1, the second third plate-shaped magnet 17 from the left). In other words, the second plate-shaped magnet 15 faces two adjacent third plate-shaped magnets 17 (in a state of overlapping positional relationship when viewed in the vertical direction), and the third plate-shaped magnets 17 also face each other. It will be in the state which faced two adjacent plate-shaped 2nd magnets 15. As shown in FIG.

Further, in the present embodiment, as shown in FIGS. 4B and 4C, the moving part 3 is placed between the linear first magnet part 5 and the linear second magnet part 7 on the plane G. At this time, the first center line C1 of the plate-like first magnet 9 of the moving part 3 is less than or equal to the second center line C2 of each of the plate-like second magnets 15 of the linear first magnet part 5 (Fig. 4(c) below the right end of the center line C2) and below the third center line C3 of each third magnet 7 of the linear second magnet portion 7 (below the right end of the center line C3 in FIG. 4(b)) It has become. In this case, as shown in FIG. 3, a repulsive force acts between the first plate-shaped magnet 9 and the second plate-shaped magnet 15 in the direction indicated by an arrow D (diagonally downward to the right in FIG. 3). and the third plate-like magnet 17, a repulsive force acts in the direction indicated by the arrow E (diagonally downward left in FIG. 3). As a result, the moving part 3 is pressed against the plane G as indicated by an arrow B, so that the moving part 3 does not rise from the plane G. It will be placed.

Next, the operation of this embodiment will be described based on the above-described configuration. First, as shown in FIG. 5, an appropriate first position between the first linear magnet portion 5 and the second linear magnet portion 7 on the plane G, for example, when viewed in the vertical direction, the front and rear plate-shaped The moving part 3 is placed (arranged) at a position between the third magnet 17 and the plate-like second magnet 15 positioned therebetween (the position of the moving part 3 on the right side in FIG. 5). At this time, the moving part 3 is stably placed on the plane G as described above, and the plate-like first magnet 9 of the moving part 3 is also perpendicular to the plane G (Fig. 3).

With respect to the first plate-shaped magnet 9, the second plate-shaped magnet 15 and the third plate-shaped magnet 17 are inclined forward and upward, and are in a positional relationship shifted in the front-rear direction. Therefore, the range where the left side 17a of the third plate-like magnet 17 faces the right side 9b of the first plate-like magnet 9 (see FIG. 4B) is the left side 9a of the first plate-like magnet 9. is smaller than the range (see FIG. 4C) where the right side surface 15b of the second plate-like magnet 15 faces (in other words, the third plate-like magnet 17 on the right side surface 9b of the first plate-like magnet 9 The exposed range (exposed area) that does not overlap with is larger than the exposed range that does not overlap with the second plate-shaped magnet 15 on the left side surface 9a of the first plate-shaped magnet 9). As a result, the repulsive force CL between the first plate-shaped magnet 9 and the second plate-shaped magnet 15 becomes larger than the repulsive force CR between the second magnet 9 and the third plate-shaped magnet 17 (CL>CR). .

In addition, as shown in FIG. In the range where the left side surface 9a of the first plate-shaped magnet 9 faces the right side surface 15b of the second plate-shaped magnet 15 (when viewed in the vertical direction, the second plate-shaped magnet 15 extends over the left side surface 9a of the first plate-shaped magnet 9). covered area) is larger on the rear side than on the front side of the first plate-shaped magnet 9 (in other words, the exposed range of the left side surface 9a of the first plate-shaped magnet 9 is larger in front than in back). Similarly, as shown in FIG. 4(b), the right side surface 9b of the first plate-like magnet 9 also faces the left side surface 17a of the third plate-like magnet 17. The area where the three magnets 17 cover the right side surface 9b of the first plate-shaped magnet 9) is larger on the rear side than on the front side of the first plate-shaped magnet 9 (in other words, the first plate-shaped magnet 9 The exposed range of the right side surface 9b of is larger on the front side than on the rear side of the plate-like first magnet 9). As a result, the repulsive force CL between the first plate-shaped magnet 9 and the second plate-shaped magnet 15 and the repulsive force CR between the first plate-shaped magnet 9 and the third plate-shaped magnet 17 are both Since the rear portion of the magnet 9 is stronger than the front portion thereof, the movable portion 3 to which the plate-like first magnet 9 is attached moves forward as indicated by the arrow A.

After that, the moving part 3 is moved to a second position (middle moving part 3 position), the moving portion 3 is stably placed on the plane G as in the first position, and the plate-like first magnet 9 of the moving portion 3 is also placed on the plane G. in a vertical position. At the second position, the range where the right side surface 15b of the second plate-shaped magnet 15 faces the left side surface 9a of the first plate-shaped magnet 9 is the opposite of the first position. The left side surface 17a of the third plate-like magnet 17 faces the right side surface 9b (in other words, the exposed area of the left side surface 9a of the first plate-like magnet 9 is smaller than the right side surface 9b). larger than the exposed area of surface 9b). As a result, the repulsive force CR between the first plate-shaped magnet 9 and the third plate-shaped magnet 17 becomes larger than the repulsive force CL between the first plate-shaped magnet 9 and the second plate-shaped magnet 15 (CR> CL).

Also in this second position, the range facing the right side surface 15b of the second plate-like magnet 15 in the left side surface 9a of the first plate-like magnet 9 is more rearward than the front side of the first plate-like magnet 9. becomes larger, and even in the right side surface 9b of the first plate-like magnet 9, the range facing the left side surface 17a of the third plate-like magnet 17 is larger on the rear side than on the front side of the first plate-like magnet 9. . As a result, the repulsive force CL between the first plate-shaped magnet 9 and the second plate-shaped magnet 15 and the repulsive force CR between the second magnet 9 and the third plate-shaped magnet 17 are both Since the rear portion of the first plate-like magnet 9 is stronger than the front portion, the moving portion 3 to which the first plate-like magnet 9 is attached moves forward as indicated by the arrow A.

In this way, as shown in FIG. 5, the moving part 3 moves from the initial first position (the position of the moving part 3 on the left side in FIG. 5) to the first first position positioned ahead of this initial first position. After moving to the second position (the position of the moving part 3 in the center in FIG. 5), the first position (the position of the moving part 3 on the left side in FIG. 5) located forward of the second position for the second time, and this It moves forward by repeating moving to a second position (not shown) located in front of the first position a second time.

Here, the moving part 3 is moved by the magnetic force generated from the plate-like first magnet 9 of the moving part 3, the magnetic force generated from each of the plate-like second magnets 15 of the linear first magnet part 5, and the linear magnetic force. This is because the magnetic force generated from each plate-like third magnet 17 of the second magnet portion 7 is constantly acting. For this reason, at least one of these magnets 9, 15, 17 may be heated to a temperature exceeding the Curie point for some reason, may be subject to a long-lasting strong impact from the outside, or may be subject to self-demagnetization. When the magnetic force is lost (demagnetized), there is no factor (energy) for moving the moving part 3, so the moving part 3 cannot move. Therefore, it should be added that the thrust generating mechanism 1 of this embodiment does not correspond to a so-called perpetual motion machine.

As described above, since the plate-like second magnets 15 of the linear first magnet portions 5 and the plate-like third magnets 17 of the linear second magnet portions 7 are inclined, the plate-like first magnets Both the repulsive force CL between the magnet 9 and the second plate-shaped magnet 15 and the repulsive force CR between the second magnet 9 and the third plate-shaped magnet 17 are greater than the front portion of the first plate-shaped magnet 9. Since the rear portion of the first magnet 9 becomes stronger, a forward thrust force can be generated in the moving portion 3, and the moving portion 3 can be advanced sufficiently forward.

Further, the moving part 3 can be moved with a simple configuration of only tilting the second plate-shaped magnet 15 and the third plate-shaped magnet 17 . In addition, by adjusting the inclination angles of the second plate-shaped magnet 15 and the third plate-shaped magnet 17, it is possible to adjust the force of movement of the moving part 3 and the like.

Furthermore, the linear first magnet portion 5 and the linear second magnet portion 7 are positioned with a shift in the front-rear direction (each of the plate-like second magnets 15 constituting the linear first magnet portion 5, Since the respective plate-like third magnets 17 constituting the linear second magnet portion 7 are shifted forward and backward), the movement of moving forward while being interposed between these magnet portions 5 and 7 It is possible to prevent the repulsive forces CL and CR acting on both sides of the portion 3 from being balanced. As a result, it is possible to prevent the moving part 3 from standing still due to the balance of the magnetic forces (it is possible to prevent the balance of the magnetic forces from acting as a brake for the moving part 3), and the smooth movement of the moving part 3 is achieved. be able to.
