ではない。[Related Art and its Problems] Generally, the relationship between the load and the deflection of a spring is represented by a spring constant. With some exceptions, this spring constant has a positive characteristic that the load increases as the deflection increases, and the spring is mounted on various industrial equipment by utilizing the positive characteristic. The negative characteristic, that is, the characteristic that the load decreases as the deflection increases, cannot be obtained by the spring alone, and it has been impossible to realize the negative characteristic and provide it for industrial use. However, in the case of a disc spring or a spring with a snap action, negative characteristics occur within a very limited range of the entire stroke of operation, but this region is not only extremely narrow but also when used beyond the region. Is not practical for practical use because the spring does not return.

定されるものである。FIG. 1 is an explanatory view showing a first embodiment of the present invention, in which a spring 1 composed of a compression spring, a limiting member 2, and a moving member 3 are shown.
And an auxiliary spring 4 constitute a spring device.
The springs 1 are wound at equal pitches and mounted on the limiting member 2. The limiting member 2 has a spring receiving seat 6 attached to be in contact with the fixed base 5, a shaft 7 integrally formed so as to extend upward from a substantially central portion of the spring receiving seat 6, and an upper end of the shaft 7. The stopper plate 8 is screwed. The spring 1 is externally inserted into a shaft 7 of the restricting member 2. The lower end of the spring 1 is supported by a spring receiving seat 6, and the upward movement of a moving member 3, which will be described later, is restricted by a stopper plate 8. 1 has an operating range limited by a spring receiving seat 6 and a stopper plate 8. The moving member 3 has a head portion 9 and a leg portion 10. The head portion 9 has a hollow shape by closing an upper end portion and inserting a stopper plate 8 of the limiting member 2 into a lower end portion. Has a rectangular box shape. The auxiliary spring 4 includes a stopper plate 8
By being attached to the upper surface, it is arranged in the head 9. The leg 10 of the moving member 3 has a double structure consisting of an inner tube and an outer tube, and is vertically connected from the lower end of the head 9. A cylindrical magnet 11 made of a permanent magnet is attached between the inner tube and the outer tube of the leg 10. The shaft 7 of the restriction member 2 is loosely inserted into the inner tube of the leg 10, while the outer tube of the leg 10 is inserted into the spring 1. The head 9 has a large diameter with respect to the leg 10, and a step 12 extending outward is formed at these boundaries, and the upper end of the spring 1 abuts the step 12. I have. This not only limits the operating range of the spring 1 described above, but also connects the upper end surface of the moving member 3 to the pressing body 13 and applies a load with the pressing body 13.
The moving member 3 moves along the shaft 7 against the urging force of the spring 1. Such a magnet 11
The limiting member 2 has a stopper plate 8 and a spring receiving seat 6 made of a magnetic material. Therefore, a magnetic attraction force acts between the moving member 3 and the limiting member 2. The auxiliary spring 4 mounted on the stopper plate 8 of the restricting member 2 is composed of a compression spring, and the lower part thereof is fitted and fixed to the boss 14 on the upper surface of the stopper plate 8. The auxiliary spring 4 is provided so as to be located within the head 9 of the moving member 3, but its length is smaller than the height of the head. In the initial state shown in FIG. A predetermined space is formed between the unit and the unit 9 and these are in a non-contact state. Therefore, no load is applied to the auxiliary spring 4 at the beginning of the movement of the moving member 3, but when the lower surface of the head 9 contacts the auxiliary spring 4 by the movement of the moving member 9, the auxiliary spring 4 receives a load from this point. The amount of deflection of the auxiliary spring 4 is added to the amount of deflection of the spring 1 and the amount of deflection of the spring 1, and the reaction force increases. In this case, the spring constant of the auxiliary spring 4 is appropriately selected depending on the industrial equipment to which the present device is applied so as to obtain the operation described later.

特性を有する。Generally, the magnetic attraction force of the magnet 11 acting on the stopper plate 8 and the spring receiving seat 6 made of a magnetic material is inversely proportional to the distance between the magnetic materials 8, 6 and the magnet 11. In addition, the amount of flexure of the compression spring 1 increases and decreases in proportion to the load from the pressing body 13, and when the amount of flexure increases, the urging force (that is, the restoring force) opposing the load increases. FIG. 2 shows these characteristic diagrams. The characteristic curve A is a deflection-load curve obtained by combining the compression spring 1 and the auxiliary spring 4, and this gradient is a spring constant (positive). Characteristic of curve A is changed gradient in two steps at one point a, while in a one-point earlier a biasing force of only a compression spring 1, the moving member 3 is assisted by one point a spring 4
, The auxiliary spring 4 bends thereafter, and the urging force of the auxiliary spring 4 due to this bending is applied. A characteristic curve B is a magnetic attraction force curve of the magnet 11 acting on the stopper plate 8, and a characteristic curve C is a magnet acting on the spring seat 6.
11 is a magnetic attraction curve of FIG. Since the magnet 11 is inserted into the compression spring 1 and provided within its working range, when the compression spring 1 bends, the distance between the stopper plate 8 and the magnet 11 increases by the same amount, and the spring receiving seat is increased. The distance between 6 and magnet 11 is reduced. Therefore, the amount of deflection of the spring on the horizontal axis is the distance between the magnetic body 6 and the magnet 11 at the same time. In this embodiment, since the magnetic members 6 and 8 are provided in the coil length direction of the compression spring 1 and the auxiliary spring 4, the load on the deflection of the compression spring and the auxiliary spring 4 and the magnetic attraction force of the magnet 11 are reduced. In the same direction, a characteristic curve D obtained by combining these loads and the magnetic attraction force is obtained.
Is a deflection-load curve by the spring device of the present embodiment. When the characteristic curve D is further analyzed, the deflection amount of the compression spring 1 is “0” in the initial state where the pressing force by the pressurizing body 13 does not act, and in this state, the magnet 11 is at the uppermost position, and Because the distance of the maximum
The magnetic attractive force between them is also “0”. Therefore, in the initial state, only the magnetic attraction between the magnet 11 and the stopper plate 8 acts effectively in the entire apparatus. Next, when the pressing body 13 is pressed, a downward external force acts on the moving member 3, whereby the compression spring 1 bends and the characteristic curve A
, The distance between the magnet 11 and the stopper plate 8 increases, and the magnetic attraction force therebetween decreases along the characteristic curve B. On the other hand, since the moving member 3 approaches the spring seat 6 and the distance between the magnet 11 and the spring seat 6 decreases, the magnetic attraction between them increases along the characteristic curve C. Since the magnetic attraction force acting on this distance is in the same direction as the pressing direction, the pressing force applied to the device is reduced. Therefore, the characteristic curve d 1 part of the entire device is lowered, indicating the so-called negative characteristics. When the pressurization is further continued, the head 9 of the moving member 3 comes into contact with the auxiliary spring 4 (a
(1 point), the auxiliary spring 4 bends. Since the spring load of the auxiliary spring 4 is added to the spring load of the compression spring 1 due to this deflection, the gradient of the spring load as a whole increases. Therefore, the characteristic curve D of the entire system by adding a magnetic attraction force is temporarily increased in the boundary point a, shows a so-called positive characteristics, further moving member 3 moves the magnet 11 and the spring seat When the distance to the spring 6 is reduced, the magnetic attraction force between the magnet 11 and the spring receiving seat 6 sharply increases with respect to the combined spring load of the compression spring 1 and the auxiliary spring 4. Therefore, the characteristic curve D is lowered from the maximum point d 2, having a negative characteristic as a whole unit.

となる。FIG. 4 shows a second embodiment of the present invention. Also in this embodiment, a compression spring is used as the auxiliary spring 4, and the auxiliary spring 4 is supported on a spring seat 6 of the limiting member 2. The auxiliary spring 4 is shorter than the spring 1, and the auxiliary spring 4 is incorporated in a double-structured spring. In this case, the auxiliary spring 4 is wound with a diameter larger than that of the spring 1, and a load is generated on the auxiliary spring 4 when the step 12 abuts on the auxiliary spring 4 by the movement of the moving member 3. Therefore, in this embodiment, the characteristic curve of the entire apparatus is similar to that of FIG.

15 is provided on the spring seat 6 of the limiting member 2.
A receiving plate 16 is attached to a lower portion of the limiting member 2, and the disc spring 15 is sandwiched between the spring receiving seat 6 and the receiving plate 16. The receiving plate 16 has a structure for supporting the lower end of the spring 1. In such a structure, the spring 1 bends due to the movement of the moving member 3, and the load of the spring 1 increases due to this bend. However, when the load becomes large enough to deflect the disc spring 15, the disc spring 15 is bent only. It has become.
