Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fountain device capable of performing rocking fountain.

[0002]

2. Description of the Related Art Conventionally, a fountain device is well known, which is constructed so as to perform a fountain from a plurality of fountain nozzles simultaneously or with a time lag. However, in this type of fountain device, since the fountain nozzle is fixed, the dynamic elements of the fountain are scarce and it is not possible to expect an attractive effect.

[0003]

The problem to be solved is that in the conventional fountain device, the dynamic elements of the fountain are scarce and the effect which attracts attention cannot be expected.

[0004]

According to the present invention, there is provided a high-pressure water supply source, a water pipe communicatively connected to the high-pressure water supply source, and a first water supply pipe.
A plurality of fountain nozzles that are swingably attached to the water pipe via swing joints and are connected in communication with the water pipes via flexible pipes, and tips of these fountain nozzles via the second swing joints. A plurality of swing arms whose parts are swingably connected, a knuckle that rotatably connects the base ends of the swing arms, and a guide that guides the movement of the knuckle, And a fountain nozzle drive source for moving the knuckle forward and backward along
By swinging the fountain nozzle at a predetermined swing angle, the purpose of performing an attention-grabbing effect was achieved.

[0005]

According to the present invention, by supplying high-pressure water from the high-pressure water supply source to the fountain nozzle through the water pipe and the flexible pipe, water can be ejected from the fountain nozzle to perform fountain. On the other hand, the output of the fountain nozzle drive source causes the knuckle to move back and forth along the guide to move the base ends of the plurality of swing arms forward and backward. As the base end portion moves back and forth, the swing arm swings around the base end portion as a swing center, and moves the start end portion forward and backward in a direction away from the knuckle and a direction approaching the knuckle. The forward and backward movements of the starting end portion in the direction away from the knuckle and the direction approaching the knuckle are transmitted to the fountain nozzle via the second swing joint.
As a result, each fountain nozzle swings at a predetermined swing angle about the swing center of the first swing joint.

[0006]

Embodiments of the present invention will be described below with reference to the drawings. 1 is a plan view showing an embodiment of the present invention, FIG. 2 is a sectional view taken along the line AA of FIG. 1, and FIG. 3 is an enlarged front view of a main part,
In these figures, 1 is a high-pressure water supply source, 2 is a high-pressure water supply pipe, 3 is a water passage pipe, 4 is a first swing joint, 5 is a flexible pipe, 6 is a fountain nozzle, and 7 is a second swing joint. , 8 is a swing arm, 9 is a knuckle, 10 is a guide, and 11 is a fountain nozzle drive source.

The high-pressure water supply source 1 is composed of a pump, a high-pressure water supply pipe 2 is connected to its discharge port, and an inlet of a ring-shaped water supply pipe 3 is connected to the outlet of the high-pressure water supply pipe 2. The water pipe 3 includes a fixed side 4 of a plurality of (e.g., 8) first rocking joints 4 formed by ball joints.
A are attached at equal intervals in the circumferential direction. A substantially central portion of the fountain nozzles 6 is attached to the movable side 4B of each first swing joint 4, and the inlets of these fountain nozzles 6 are annular water pipes 3 via flexible pipes 5 made of pressure resistant hoses.
It is connected to the.

On the other hand, a movable side 7B of a second swing joint 7 formed of a ball joint is attached to the lower end of each fountain nozzle 6, and the fixed side 7A of the second swing joint 7 is plural (eight). Is attached to the tip of the swing arm 8. Then, the base end portions of the swing arms 8 are assembled and rotatably connected to the knuckle 9. That is, the knuckle 9 has a cylindrical shape as shown in FIG.
Eight connecting grooves 9A are formed at the upper end thereof so that the base ends of the swinging arms 8 are assembled and rotatably fitted. The base ends of the swinging arms 8 are fitted into these connecting grooves 9A. After that, by inserting the connecting pin 9B into the base end portion, the base end portions of the swinging arms 8 are assembled and can be rotatably connected to the knuckle 9.

On the other hand, the knuckle 9 is slidably fitted onto a guide 10 having a vertical axis C, and
It is connected to a fountain nozzle drive source 11 composed of a cylinder device. That is, the piston rod 11A of the fountain nozzle drive source 11 is connected to the knuckle 9.

With such a structure, the high-pressure water supply source 1
The high-pressure water is sent to the eight fountain nozzles 6 by the route of the high-pressure water supply pipe 2 → the ring-shaped water pipe 3 → the flexible pipe 5 by operating the pump constituting the To eject multiple fountains at the same time.

On the other hand, the cylinder rod functioning as the fountain nozzle driving source 11 is operated to drive the piston rod 11A.
Is moved back and forth with a predetermined stroke amount, the guide 10
The knuckle 9 moves back and forth in the direction of the axis C along with, and the base ends of the eight rocking arms 8 move back and forth in the same direction. As a result, each swing arm 8 swings around the base end, and as shown in FIG. 5, the start end of the swing arm 8 moves back and forth in a direction away from the knuckle 9 and a direction approaching the knuckle 9. The movement in which the starting end of each swing arm 8 moves back and forth in the direction away from the knuckle 9 and in the direction approaching the knuckle is transmitted to each fountain nozzle 6 via the second swing joint 7. As a result, each fountain nozzle 6 swings around the first swing joint 4 at a predetermined swing angle about the swing center. As a result,
A fountain rich in dynamic elements such as petals swinging in the opening and closing direction can be executed to produce an effect that draws attention.

In the above-mentioned embodiment, the structure in which eight fountain nozzles 6 are used has been described. However, the number of fountain nozzles 6 used is not limited to the above-mentioned embodiment, and any desired plural number may be used. I wish I had it. Further, the water pipe 3 is not limited to the annular shape, and a non-annular water pipe 3 having at least one axial end closed may be used.

[0013]

As described above, according to the present invention,
It is possible to continuously execute a fountain rich in dynamic elements that give the feeling that the petals swing in the opening and closing directions. Therefore, a production that draws attention can be expected sufficiently.
