BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water nozzle swinging device for jetting a jet water stream, and more particularly to a water nozzle swinging device for jetting a jet water stream sideways in a pool facility or a bathhouse.

[0002]

2. Description of the Related Art In recent years, as a part of leisure facilities, there have been provided bath facilities such as large pools and baths, and various pool facilities and bath facilities disposed in a part of the bath facilities. As one of the facilities in the facility, there is a device that jets a jet stream of water horizontally toward the body of a bather.

[0003]

In conventional equipment for jetting jet water in a lateral direction, since the water nozzle is fixed, the position where the jet water stream hits is fixed. For this reason, there is an inconvenience that the bather has to change his posture when trying to apply the jet stream to the whole body. The present invention has been made in view of such a point, and an object of the present invention is to provide a device of a water nozzle that allows a water bather to shower a jet water flow on the whole body without changing the posture.

[0004]

In order to achieve the above object, the present invention supports a water nozzle for jetting a jet water flow on a base so that the water nozzle can be swung in a two-dimensional direction. A swing drive mechanism that swings and swings is linked to an air actuator such as a reciprocating rotary air motor or air cylinder via a speed reduction mechanism and a one-way clutch, and the speed reduction mechanism is derived from the one-way clutch. A pin gear fixed to the pin gear and a rotating disc with an engaging groove formed on the peripheral surface for engaging the pin of the pin gear or a combination of a worm gear and a wheel gear, and the swing drive mechanism of the rotating disc. A combination of an eccentric pin projecting at an eccentric position in the side plate part and a long groove hole formed in the water nozzle in parallel with the water ejection axis while the eccentric pin engages, or a cam and a spring. And a combination is characterized by being configured so as to intermittently swinging the swing water nozzle in reciprocating rotation or reciprocation of the air actuator.

[0005]

According to the present invention, a water nozzle for ejecting a jet water flow is supported on a base so that the water nozzle can be swung in a two-dimensional direction. A pin gear, which is linked to a reciprocating air actuator via a clutch and has a speed reduction mechanism fixed to the tip of a rotating shaft derived from a one-way clutch, and an engagement groove that engages with the pin of the pin gear are formed on the circumferential surface. An eccentric pin that is formed by combining with the formed rotating disc or by combining a worm gear and a wheel gear, and the oscillating drive mechanism is provided at the eccentric position on the side plate portion of the rotating disc, and this eccentric pin is engaged. In the combined state, the water nozzle is configured with a combination of a slotted hole formed parallel to the water ejection axis or a combination of a cam and a spring. Since the structure so as to swing, ejection direction from the water nozzle is changed with time, it is possible to blow a jet water flow throughout the body.

As shown in FIGS. 4 and 5, the one-way clutch (19) fixes the rotor (23) having an engaging recess on the peripheral surface to the input shaft (20) and engages with the casing (24). The rotor (23) is supported by the casing (25) by pivotally supporting the engaging pawl (25) and elastically biasing the engaging pawl (25) in the direction of engaging the rotor (23) with the spring (33). 24) is configured to be driven in one direction (clockwise in the figure), and is formed by fixing the output shaft (22) to the casing (24).

In FIG. 1, reference numeral (26) is a jet water jet nozzle.
It is a water supply channel to (2), and the water pump (27) arranged in this water supply channel (26) is controlled to operate by a command from the control device (28). Further, reference numeral (29) in FIG. 1 is a working air supply / discharge system for the air motor (3), and this working air supply / discharge system (29) is a pair of air ports provided in the air pump (30) and the air motor (3). (31) The (31) and (31) are connected via the electromagnetic four-way valve (32), and the electromagnetic four-way valve (32) is switched by a command from the above-mentioned control device (28) to rotate the air motor (3). It is configured as follows.

In the jet water jet device constructed as described above, when the water bather presses the start switch, the water pump (27) is actuated and the jet water is ejected from the jet water jet nozzle (2) to start the start. The discharge pressure increases after a few seconds.
On the other hand, the air pump (30) also starts operating based on the operation of the start switch, and the electromagnetic four-way valve (32) is delayed by a predetermined interval (for example, 1 second) after the discharge pressure reaches a predetermined pressure (for example, 2 seconds) after the water pump is started. Start valve opening / closing switching in 0.5 seconds).

When the solenoid four-way valve (32) is switched, the air motor (3) repeats normal and reverse rotation. The forward / reverse rotation at a constant interval is an intermittent rotation due to the action of the one-way clutch (19), and the intermittent rotation causes the swing drive mechanism (8) to move through the pin gear (16) and the rotary disk (12) to 1 The jet water jet nozzle (2) is stepped up and down step by step by pitch.
Therefore, the jet water discharged from the jet water jet nozzle (2) moves within a certain angle range. In this case, the jet water jet nozzle (2) is set at a horizontal position as a standby position.

When a fixed time, that is, several cycles, elapses after the start switch is operated, the operation of the water pump (27) and the electromagnetic four-way valve (32) is stopped to end the discharge. In addition, if a water bather operates the swing stop switch while high-pressure water is being discharged from the jet water jet nozzle (2),
The jet water jet nozzle (2) is stopped at that position, and by operating the start switch again, it is programmed in the control device to continue the original swing from the stop position for the rest of the time. . In this case, the jet water jet nozzle (2) returns to the horizontal position after the discharge is stopped.

In the above embodiment, the reduction gear mechanism (9) is formed by the pin gear (16) and the rotary disk (12) having the engaging groove (17) formed on the peripheral surface. When the jet water jet nozzle (2) in the standby position tries to naturally oscillate due to the reaction force due to the moment of the water stream and the weight of the nozzle, the oscillating force causes the swinging drive mechanism (8) and the speed reduction mechanism (9). In order to prevent transmission to the power transmission mechanism (5) via this, if the speed reduction mechanism (9) is composed of a normal gear transmission mechanism, the reverse driving force is smoothly transmitted to the one-way clutch (19), The nozzle body (6) operates regardless of the control command.
