Description

[Detailed Description of the Invention] (Industrial field of application) The present invention relates to a dynamic art work of stones installed in a park or other places where many people gather to create a peaceful atmosphere.

(Prior art and its problems) As one of the conventional art works of stone, as shown in FIG. 1, a spherical stone 1 is loosely inserted into a spherical concave portion 21 of a pedestal 2 and the lower side of the center of the spherical concave portion 21. There was used a spheroidal stone rotating device which presses water from the above through the water conduit 4 by the pump 3 to float and rotate the spheroidal stone 1.

The water guide tube 4 into which the water is press-fitted has the opening 4a of the spherical recess 21 slightly inclined in one direction in order to rotate the spherical stone 1 in a certain direction.

For this reason, the water that has been pressed in pushes up the spherical stone 1, and at the same time, a large amount of water flow is generated in the inclination direction of the opening 4a, causing the spherical stone 1 to rotate in one direction (thick arrow), and the spherical concave portion 21 and the spherical stone 1 It flows out through the gap with 1 onto the pedestal 2 and the spherical recess 21
It circulates to the pump 3 through the drainage pipe 23 from the annular groove 22 provided around the pump as shown by the thin arrow.

As a result, the rotating direction of the spherical stone 1 is constant, which is rare at first glance, but it may get tired when viewed for a long time.

Further, since the spherical stone 1 is made of natural stone, the rotation may be difficult to recognize unless it is illuminated brightly.

It is an object of the present invention to solve the above-mentioned problems and provide a dynamic art piece of stone in which an artistic expression means is constructed to emphasize the effect of accenting an atmosphere.

(Means for Achieving the Object) In order to achieve the above-mentioned object, the spherical stone 1 and a pedestal 2 provided with a spherical concave portion 21 into which the lower portion of the spherical stone 1 is loosely inserted are provided. In a spheroidal stone rotating device equipped with a water conduit 4 into which water is press-fitted from the lower side at the center of 21, a specific artistic expression means is provided on the spheroidal stone 1 or the pedestal 2.

As the artistic expression means described above, (1) a lighting device 52 which is completely embedded in the spherical recess 51 of the pedestal 5 and whose surface is aligned with the surface of the spherical recess 51 (2) The surface of the spherical stone 1 is inlaid, and the filling material of this inlay is of substantially the same density as the sphere, and the surface after polishing is the original spherical surface without any irregularities, and The positions of the center of gravity and the center of gravity of the sphere before inlaying are substantially the same. (3) In addition to the main water pipe 62 that press-fits water from below into the center of the spherical recess 61 of the pedestal 6, the spherical recess 61 There is one in which a plurality of auxiliary water guiding pipes 63 are provided in the middle part, which are oriented in a direction warped with respect to the center line of the spherical concave portion 61, so that the rotating direction of the spherical stone 1 can be controlled.

(Operation) As described above, the expression function can be enhanced by providing various unusual movements and visual enhancement functions such as light and inlaid patterns in addition to the conventional slow and uniform movements.

(Embodiment) Embodiment 1 FIG. 2 is a sectional view of a main part of a pedestal portion of the present embodiment. The pedestal 5 of this embodiment is provided with an illuminating device 52 toward the inner surface of the spherical recess 51, and the illumination surface of the illuminating device 52 faces the spherical recess 51 and has the same spherical surface. Has been done.

The other parts are the same as in the conventional example, and the description of the same parts will be omitted.

 Next, the operation of this device will be described.

Since the rotating operation of the spherical stone 1 is as described above, the description is omitted.

Since the circulating water is illuminated by the illumination device 52, the spherical stone 1
The water flowing out from the gap between the spherical concave portion 51 and the spherical concave portion 51 is refracted so that the light reaches the outflow portion and emphasizes the artistic expression effect.

Example 2 In this example, the surface of the spherical stone 1 is engraved, and a material having a color tone different from that of the material of the spherical stone 1, such as plastic or metal, is filled in the engraved portion, and the spherical stone 1 is ground again to finish.

In this case, it is necessary to select the filling material so that the center of gravity after finishing matches the center of gravity before engraving.

In the case of this embodiment, the rotation state becomes clear due to the pattern on the surface of the spherical stone 1, and the artistic expression effect can be emphasized. As an example thereof, an emphasizing means such as imitating a rotating earth by forming a pattern like a globe can be considered.

Embodiment 3 In this embodiment, as shown in FIG. 3, the water guiding pipe of the pedestal 6 has a main water guiding pipe 62 provided in the central portion of the spherical recess 61 and a spherical surface of the spherical recess 61 surrounding the main driving water pipe 62. A plurality of auxiliary water conduits 63 having openings are provided in the part. in this case,
Unlike the case of the conventional example and each of the above-described embodiments, the main water pipe 62 has an opening at the upper end facing straight up without inclination.

A main pump 64 is provided in these main water pipes 62, and a plurality of auxiliary water pipes 63, 63 ,.
4a, ... are provided.

Since the annular groove 65 and the drain pipe 66 are the same as those in the conventional example and other examples, the description thereof will be omitted.

 Next, the operation in the case of this embodiment will be described.

When water is pressed into the main water pipe 62 by the main pump 64, spherical stone 1
Is slightly lifted by water pressure, and the pressure water overflows from the gap between the spherical stone 1 and the spherical recess 61, and is recovered from the annular groove 65 through the drain pipe 66.

At this time, if pressure water is fed into only one of the auxiliary water guiding pipes 63, the spherical stone 1 rotates in a plane vertical to the direction of the auxiliary water guiding pipe 63.

Here, if the openings of the respective auxiliary water guiding pipes 63 are tilted in the lateral direction, the spherical stone 1 is rotated in the lateral direction by the pressure water from the auxiliary water guiding pipes 63.

Therefore, by controlling the opening directions of the respective auxiliary water guiding pipes 63 in different directions to control how the pressure water is discharged from the respective auxiliary water guiding pipes 63, the rotation direction of the spherical stone is freely controlled. You can

(Effect of the Invention) As described above, various artistic means can be applied to the conventional rotating device for spherical stones, so that the expression effect can be increased.
