[0009]

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described. FIG. 1 is a front view showing this structure of the resonance pendant of the present invention, and FIG. 2 is a plan view seen from above. Resonance swing 1 is a pillar 11 and a pillar 12, which consist of two pillars opened in an inverted V shape, a horizontal girder 13 supported horizontally by the pillars 11 and 12, and a hanging metal fitting with a predetermined spacing on the lateral girder 13. It is composed of a rocking member 16 suspended horizontally by 14 and 15 and two platforms 19 and 20 suspended from the rocking member 16 by ropes 17 and 18.

The pillars 11 and 12, and the horizontally supported cross girders 13 are not particularly different from the structure used in the conventional swing, and are composed of iron pipes or the like, and are arranged on the horizontal surface E. It is fixed by an appropriate means such as concrete.

As shown in the perspective view of FIG. 3, the swing member 16 is a rod-shaped member made of a rigid body such as iron, and has hooks 16a and 16b provided on the upper side thereof, and the hooks 16a and 16b are provided. Are respectively locked to the other ends of the suspending metal fittings 14 and 15 whose one ends are fixed to the stoppers 13a and 13b arranged at predetermined intervals on the horizontal beam 13, and the swinging member 16 is attached to the horizontal beam 13. It is swingably suspended. The hanging metal fittings 14 and 15 may be made of chains or wire ropes.

Hooks 16c and 16d are provided on the lower side of the swing member 16. The number of hooks 16c and 16d on the lower side is not limited to two, and a plurality of hooks 16c1, 16c2, 16d1, 16d2, etc. are provided at appropriate intervals in advance, and the hooks at convenient positions are used. Should be available. With this configuration, the platform can be suspended at an appropriate position on the swing member.

The pedestals 19 and 20 are made of synthetic resin and are formed into a hollow body having a substantially spherical shape and a flat surface portion formed on the upper surface. A hole is provided in the central portion of the flat surface portion of the upper surface. There is. The other ends of the ropes 17 and 18 whose one ends are fixed to the hooks 16c and 16d of the rocking member 16 are passed through a hole provided in the central portion of the platform to the inside, and an appropriate means, for example, The platform 19 is fixed to the platform by tying it to a fixing member (not shown) provided inside the platform, and the platforms 19 and 20 are suspended on the swing member 16.

The means for fixing the rope to the platform is preferably of a structure that allows the children to easily adjust the length of the rope by themselves. Further, it goes without saying that the material forming the platform is not limited to the synthetic resin, and may have an appropriate shape other than the substantially spherical shape. A chain or the like may be used instead of the rope.

Next, the operation will be described. A person rides on each of the platforms 19 and 20, and at the beginning, only one platform is shaken greatly and the other platform is fixed. Here, as an example, it is assumed that the platform 19 is rowed and swayed, and the platform 20 is held so that the pedestrian does not move, for example, by touching his / her feet on the ground. When the platform 19 starts to swing with a large amplitude, the foot holding the platform 20 is released from the ground.

After that, when the platform 19 and the platform 20 are not rowed and are swayed in a natural manner, the platform 20 starts to sway naturally and the amplitude of the sway gradually increases. On the other hand, the swing amplitude of the platform 19 gradually becomes smaller, and when the swing of the platform 19 stops, the amplitude of the platform 20 becomes maximum. After that, the swing amplitude of the platform 20 gradually decreases, the platform 19 starts to swing again, and the swing amplitude gradually increases. After that, even though the maximum amplitudes of the platforms 19 and 20 described above are gradually attenuated, the shaking motion described above is repeated many times, so that a mysterious phenomenon can be experienced and enjoyable to play.

In the above description, the platform 19 is shaken at the beginning and the platform 20 is held so as not to move. However, the platform 20 is initially shaken and the platform 19 is held so as not to move. Even if it does, it moves in exactly the same way. It should be noted that the platform may be rocked in a plane substantially perpendicular to the longitudinal direction of the rocking member, but the platforms may be rocked in any direction as long as the platforms do not collide with each other.

[0018] When the length of the rope that suspends the platform is changed, how it swings, how two people ride on one platform and how one platform rides on the other platform Children will be able to experience the resonance phenomenon (playing together) while playing, devising such ways as changing the position where they are hung on the swinging member will make a difference in how they swing.

In the resonance swing described above, each platform is suspended by one rope, but it may be constructed by suspending it by two or more ropes. Good.

The principle of the resonance swing of the double pendulum described above is transfer of energy by resonance. When one of the platforms (hereinafter, platform 19) is rocked, the rocking member 16 also rocks. Therefore, the fulcrum 16d of the rope of the other platform 20 also slightly sways. When this swing coincides with the natural vibration of the platform 20, the platform 20 starts to swing due to resonance. At this time, the vibration energy of the platform 19 is transmitted to the platform 20, so that the vibration of the platform 19 is gradually reduced and stops.

[0021]

[Effect of the invention]

 As described above, the resonance swing of the present invention comprises a horizontal girder horizontally supported by a column, and a swing member horizontally swingably supported by a suspending metal at a predetermined distance from the horizontal girder. It is composed of two platforms that are swingably suspended from a swing member by a rope. The platform that suspends the platform can be changed so that the position at which the platform is suspended can be changed. The adjustable loop length allows children to play with resonant swings while changing the number of people on the platform, adjusting the length of the rope, and changing the hanging position. You can experience the resonance phenomenon, which is the basic concept of energy transfer, along with play, by devising and exploring.
