Abstract

PURPOSE:To enable a swimmer to swim successively keeping the balance of a body by detecting the advancing position or the retreating position of the swimmer, and changing the direction of a water flow to a water tub based on position detection. CONSTITUTION:When the swimmer 3 is driven out gradually as swimming against the water flow generated at a water flow generating means 2 in the water tub 1, the position of the swimmer 3 is detected by either a forward detecting means 4a or a rearward detecting means 4b, and the flow velocity of the water flow by the water flow generating means 2 is controlled by a control means 5. Therefore, the swimmer 3 is returned to the center part of the water tub 1, and the swimmer can swim successively without being driven out to the terminal of the water tub 1. The swimmer 3 in swimming can swim without generating a standing state due to the breakdown of balance of the body by changing the direction of the water flow to the water tub 1 by the water flow generating means 2 by a water flow direction control means 6 when the flow velocity of the water flow is adjusted. Thereby, the swimmer 3 can swim keeping the balance of the body successively for a long time.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a running water pool that allows swimming in an aquarium due to water current, and it is possible to swim in an aquarium continuously for a long time. This relates to running water pools.

[Conventional technology]

Conventionally, the present applicant has proposed, for example, a running water pool in which water is jetted into an aquarium from a water spout via a pump to generate a water flow in the aquarium, and the user can swim against this water flow. No. 1-105606 has been filed.

[Invention or problem to be solved]

However, in the conventional example described in Section 1, swimmers do not feel as they swim due to differences in water flow speed at each location in the aquarium, radial distribution of water flow direction from the water spout, etc. This poses a problem in that it is difficult to keep swimming while maintaining the swimming position in the center of the tank, and it is only possible to swim continuously. For this reason, Japanese Patent Application Laid-Open No. 62-1999 proposed a method in which the speed of the water flow was adjusted according to the swimming speed of the swimmer by detecting the swimming position of the swimmer and adjusting the amount of water jetted from the water spout.
290479 and JP-A-60-179080 have been proposed. For example, as shown in FIG. 10, these devices are provided with detection sensors as detection means 4 for detecting the swimming position of the swimmer 3 at the front and rear parts of the inner wall surface of the aquarium l, and the front detection When the means 4a detects that the swimmer 3 is moving forward in the aquarium 1, the water current becomes faster and pushes the swimmer 3 backward in the aquarium 1, and the rear detection means 4b detects that the swimmer 3 is moving forward in the aquarium 1. By detecting that the swimmer 3 is moving backward in the aquarium 1, the water flow is slowed down so that the swimmer 3 can be moved forward in the aquarium 1.

However, when the water flow is made faster to push the swimmer 3 backward, the water flow from the water spout 2a simply increases and the water flow speed becomes faster. The water flow becomes faster, and becomes slower in deeper areas.As a result, the balance of the swimmer 3's body is lost, and the swimmer 3's body becomes in a standing position as shown in Figure 11, and the swimmer 3 continues to swim. There was a problem that I couldn't do it.

The present invention seeks to solve the problem described above.
The purpose is to provide a running water pool in which swimmers can swim continuously without losing their body balance when adjusting the flow rate.

[Means to solve the problem]

In order to achieve the above object, the running water pool A of the present invention includes: a water flow generating means 2 for generating a water flow in the water tank 1; a detection means 4 for detecting the position of the swimmer 3 in the water tank 1; In a running water pool comprising a control means 5 for controlling the flow rate of the water flow by the water flow generating means 2 according to a signal from the detection means 4, a front detection means 4a for detecting the forward position of the swimmer 3 is provided at the front of the water tank l. A rear detection means 4b for detecting the retreating position of the swimmer 3 is provided at the rear of the aquarium 1, and when the position of the swimmer 3 is detected by the front detection means 4a and the rear detection means 4b, the water flow generation means 2 moves the swimmer 3 into the aquarium 1. It is equipped with a water flow direction control section 6 that changes the direction of the water flow.

[Effect]

Therefore, the swimmer 3 is in the water tank 1 by the water flow generating means 2.
The swimmer 3 swims by swimming against the water current generated by the swimmer, and as the swimmer 3 is gradually washed away as the swimmer 3 swims, the position of the swimmer 3 is detected by either the front detection means 4a or the rear detection means 4b. By controlling the flow rate of the water flow generated by the water flow generation means 2 by the control means 5, the swimmer 3 is returned to the center of the aquarium 1 and can swim continuously without being swept away to the edge of the aquarium I. . By changing the direction of the water flow into the aquarium 1 by the water flow generating means 2 by the water flow direction control unit 6 when adjusting the flow speed of the water flow, the balance of the body of the swimmer 3 during swimming may be lost, causing the swimmer 3 to The swimmer 3 can swim continuously for a long time while maintaining his/her body balance without having to stand up.

〔Example〕

Hereinafter, the present invention will be explained in detail based on illustrated embodiments.

In the flowing water pool A, a water current is generated in the aquarium 1, and swimming is done by swimming against this water flow. This allows the user to swim in a short aquarium without the need for a long aquarium.

As shown in FIG. 1, one end of this water tank 1 is provided with a water spout 2a through which the sucked water in the water tank 1 is spouted out by a circulation pump 5a, and the other end is provided with a water spout 2a facing this water spout 2a. A suction port 2b is provided for sucking water in the aquarium 1. It also constitutes a water flow generating means 2 for generating a water flow within the water tank 1 at the water spout 2a and suction port 2b. The flange portion of the water tank 1 is provided with detection means 4 for detecting the position of the swimmer 3 within the water tank 1. As this detection means 4, for example, an optical sensor is used. Of course, other sensors may also be used. The detection means 4 are provided at the front and rear parts of the aquarium 1, with the front detection means 4a provided at the front and the rear detection means 4b provided at the rear. The forward detection means 4a can detect the forward movement of the swimmer 3 within the tank 1, and the rear detection means 4b can detect the backward movement of the swimmer 3 within the tank 1. The optical sensor constituting the detection means 4 detects the position of the swimmer 3 by detecting the head of the swimmer 3 when the swimmer 3 is doing breaststroke; When the swimmer 3 is performing crawl, backstroke, butterfly, etc., the hands of the swimmer 3 are detected when they are extended forward during swimming. The illustrated embodiment shows the detection state when the swimmer 3 is crawling. The water flow generating means 2 is controlled by a control means 5, and the flow rate of the water flow by the water flow generating means 2 is adjusted by operating the control means 5. A water flow direction control unit 6 is provided near the water flow generation means 2 to change the direction of the water flow into the aquarium 1 by the water flow generation means 2 by detecting the position of the swimmer 3 by the front detection means 4a and the rear detection means 4b. .

As shown in FIGS. 3 and 4, this water flow direction control section 6 is constituted by a nozzle drive device 6C formed by incorporating a drive device 6b such as a motor inside a box body 6a.
A connecting rod 7 that protrudes from the water spout 2a and is movable up and down is connected and fixed to a drive device 6b.
When activated, the water spout 2a rotates up and down. That is, to explain in detail with reference to the system diagram shown in FIG. 9, when the position of the swimmer 3 is detected by the detection means 4, a signal indicating the position of the swimmer 3 is sent to the control circuit 8. The signal is sent to the circulation pump 5a, which is the control means 5, and the nozzle drive device 6C, which is the water flow direction control unit 6, and the circulation pump 5a adjusts the amount of water ejected from the water spout 2a, and the nozzle drive device 6C.
This causes the water spout 2a to rotate up and down, thereby changing the direction of the water flow. As for the above control method, when the swimmer 3 moves forward in the aquarium 1, the flow velocity of the water flow is increased by the control means 5 as shown in FIG. (Part A in Figure 5)
In other words, as shown in Fig. 7, water is spouted toward the surface side of the water tank l, water is spouted at this high flow rate for a certain period of time, and - after a certain period of time, the water spout 2a is directed downward (first direction). As shown in Figure 8, the water will be spouted towards the bottom of the tank 1, and after a certain period of time, the water spout 2a will again be oriented in two directions (horizontal direction). By gradually shortening the interval between the upward and downward movements of the water spout 2a, and repeating this operation, the swimmer 3 can be brought into the tank without the swimmer 3 standing.
It pushes back inside. In this case, water spout 2
The ratio of the upward and downward directions of a is determined by the water flow.
Since it is necessary to push back backwards, the time required for it to turn upward should be slightly longer. Further, when the swimmer 3 moves backward in the aquarium 1, the control means 5 slows down the water flow speed as shown in FIG. The direction of 2a is downward (part B in Figure 6), and water is spouted toward the bottom of the tank 1, and after a certain period of time, the water spout 2a
The water spout 2a is directed upward again in the horizontal direction (part A in Figure 6), and by repeating this operation while gradually shortening the time interval between the upward and downward movements of the water spout 2a, the swimmer 3 Do not stand upright (swimmer 3 or tank 1).
It allows for gradual progress within the organization. in this case,
The ratio of the upward and downward directions of the water spout 2a is such that the time required for the downward direction is slightly longer since it is necessary to move the swimmer 3 forward.

When the swimmer 3 is gradually swept backward as he swims, the detection means 4 detects a shift in the position of the swimmer's body in the water. 1, the optical sensor detects the shift of the swimmer 3. In other words, the rear detection means 4b detects that the swimmer 3 is moving backward, and the rear detection means 4b detects that the swimmer 3 is moving backward. The signal is sent to the control means 5 via the control circuit 8, and the control means 5 controls the flow rate of the water flow from the water jet I=12a, and the water flow direction control section 6 controls the direction of the water jet nozzle 2a. This system adjusts the speed of the water flow and the direction of the water flow to return the swimmer 3 to the center of the aquarium 1 without losing the balance of the body during swimming. In addition, if the swimmer 3 is swimming fast and moves forward in the tank 1, the speed of the water flow is increased and the direction of the water flow is adjusted so that the swimmer 3 can move to the center of the tank 1 without standing. It is something to return.

In this way, the detection means 4, the water flow generation means 2, the control means 5,
Even if the swimmer 3 shifts position in the aquarium 1 by the water flow direction control unit 6, the detection means 4 detects the position of the swimmer 3, and the water flow is controlled so that the swimmer 3 can move naturally without losing his/her body balance. It will be returned to the central part in
Even in an aquarium with a small space, it is possible to swim continuously for a long time in the central part of the aquarium 1 without hitting the surrounding wall with one's hands or feet.

As described above, the running water pool of the present invention includes a water current generating means for generating a water current in the aquarium, a detecting means for detecting the position of a swimmer in the aquarium, and a water flow generated by the water current generating means based on a signal from the detecting means. A running water pool comprising: a front detection means for detecting the forward position of the swimmer at the front of the tank; and a rear detection means for detecting the backward position of the swimmer at the rear of the tank; and a water flow direction control section that changes the direction of the water flow into the aquarium by the water flow generating means by detecting the position of the swimmer by the front detection means and the rear detection means, so that the position of the swimmer can be detected by the detection means. The water flow rate and direction are controlled so that the body is returned to the center naturally without losing its balance and standing up. However, it is possible to swim continuously for a long time in the center of the tank without touching the surrounding wall with one's hands or feet.
