Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water play equipment with a propulsion device, which slides on a water surface. 2. Description of the Related Art Conventionally, various small and lightweight floating playground equipments have been proposed, and it is desired that the floating playground equipments change the posture of the hull according to the driving situation. For this reason, it is conceivable to provide a plate that swings around an axis extending in the width direction of the hull, and push down this plate around the axis to immerse it in water to change the attitude of the hull. By the way, in a water play equipment having a bar handle, a straddle type seat located behind the bar handle, and foot decks located on both sides of the straddle type seat, the straddle type is used for turning. Since the occupant seated on the seat greatly tilts the body to the left and right to greatly tilt the hull to the left and right, depending on the position where the plate is provided, when the plate is tilted greatly to the left and right, the plate may interfere and the turning performance may be impaired. SUMMARY OF THE INVENTION The present invention has been made to solve such a conventional problem, and is capable of changing the attitude of a hull with a simple structure and is excellent. It is an object of the present invention to provide a water playground equipment that can obtain various turning characteristics. The present invention has a bar handle, a straddle-type seat located behind the bar handle, and a foot deck located on both sides of the straddle-type seat. In the play equipment, a plate that is substantially flush with the bottom of the ship is provided, and both side edges of this plate are positioned inside both side plates of the hull, and the plate is provided on the front end edge of the plate and extends around the axis extending in the width direction of the hull. Further, an operating means for supporting the plate in a swingable manner and pushing the rear end portion of the plate down around the shaft to immerse the plate in water and a returning means for the plate are provided. With the above structure, the following operational effects are achieved. A plate provided so as to be substantially flush with the bottom of the ship is swingably supported about an axis extending in the width direction of the hull, and the plate is pushed down about the axis to be immersed in water. Since the returning means is provided, the attitude of the hull can be changed by immersing the plate in water as necessary. Since the shaft is provided at the front end edge of the plate and the rear end of the plate is pushed down around the shaft, the operating means for pushing down the plate is damaged and the plate tries to rotate unintentionally around the shaft. Also, due to the water pressure, the force to return the plate to its original position acts, enabling stable navigation. That is, when the shaft is attached to the middle part or the rear part of the plate in the front-rear direction, if the operating means for pushing down the plate is damaged, the plate rotates around the axis in the direction opposite to the direction in which the plate is returned due to the water flow caused by the running of the ship. Although there is a risk of receiving a force, when the shaft is provided at the front end edge of the plate as described above, the force received by the water flow due to running always acts in the direction of returning the plate. Since the both side edges of the plate are positioned inside the both side plates of the hull, the passenger seated on the straddle type seat during turning makes the body lean left and right greatly and the hull leans greatly left and right. Also, the plate does not get in the way, and good turning performance can be obtained. 1 to 3, an operating handle (bar handle) 2 is installed on a hull 1 of a water play equipment at a substantially central portion of the hull, and a seat seat extending in the stern direction on the rear side thereof. 20 is formed, and further, on both sides thereof, a foot deck 21 that opens to the stern end is formed. The hull 1 is configured to slide on the water surface by operating a propulsion device (not shown). A flat plate-like plate 4 is arranged on the bottom of the ship at a substantially central portion in the longitudinal direction of the hull 1. The plate 4 is configured to be rotatable around a shaft 6 at its front end, and is pushed down by an operating shaft 40 to be immersed in water. Is configured to. A pedal 7 is arranged at the front end portion of the foot deck 21 on the boat, and a person straddling the seat 20 operates the cylinder 71 by operating the pedal 7, and the pressure oil supplied through the oil pipe 72 operates the cylinder 73. This cylinder 73
The plate 4 is operated by the cylinder rod (which constitutes the operating shaft 40). The pedal 7
By releasing the stepping force, it is configured to be restored by an appropriate restoring means. FIG. 4 shows another embodiment of the present invention. An operating shaft 50 directly connected to a pedal 8 is connected to a plate 5 rotatably mounted around a shaft 6 at a front end portion, and the pedal 8 is connected to the operating shaft 50. The rear end is rotatably supported around the shaft 51,
The return spring 52 exerts an upward force that raises the front end of the pedal 8. And pedal 8
By depressing against the force of the spring 52, the plate 5 is directly pushed down to be immersed in the water. In each of the above embodiments, the plates 4 and 5 are
Each of them forms part of the chine or part of the bottom of the ship, and is housed so that it does not protrude from the bottom of the ship when it is inactive and therefore does not create any resistance during normal cruising. In the configuration shown in FIGS. 1 to 3, the pedals 7 are depressed to operate the cylinders 71 and 73 to move the plate 4
Immerse in the water. Further, in the configuration of FIG. 4, the plate 5 is directly immersed in the water by depressing the pedal 8. When the plates 4 and 5 are immersed in the water, a great resistance is generated in the boat while traveling, and a force that greatly changes the attitude of the hull is generated. Therefore, the plates 4, 5
It is possible to make a sharp turn by suddenly actuating one of the two. The magnitude of the force that changes the attitude of the hull at that time can be adjusted by the rotation angle of the plate, that is, the tilt angle. The plate 4 is shown in FIG.
As shown in Fig. 5, the V-shaped bottom is attached so as to be inclined along the inclined surface of the bottom plate, and is arranged near both sides of the hull, and the left and right plates can be operated independently. In addition, when only one plate is operated at the time of turning, the hull can be easily tilted, whereby turning can be effectively performed. The above-mentioned structure achieves the following operational effects. A plate provided so as to be substantially flush with the bottom of the ship is swingably supported about an axis extending in the width direction of the hull, and the plate is pushed down about the axis to be immersed in water. Since the returning means is provided, the attitude of the hull can be changed by immersing the plate in water as necessary. Since the shaft is provided at the front edge of the plate and the rear end of the plate is pushed down around the shaft, the operating means for pushing down the plate is damaged and the plate tries to rotate unintentionally around the shaft. Also, due to the water pressure, the force to return the plate to its original position acts, enabling stable navigation. That is, when the shaft is attached to the middle part or the rear part of the plate in the front-rear direction, if the operating means for pushing down the plate is damaged, the plate rotates around the axis in the direction opposite to the direction in which the plate is returned due to the water flow caused by the running of the ship. Although there is a risk of receiving a force, when the shaft is provided at the front end edge of the plate as described above, the force received by the water flow due to running always acts in the direction of returning the plate. Since both side edges of the plate are positioned inside the both side plates of the hull, an occupant seated on a straddle-type seat leans the body to the left and right and leans the hull to the left and right greatly during turning. Also, the plate does not get in the way, and good turning performance can be obtained.
