Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a swimming range finder in which a swimmer is equipped with a measuring instrument having a basic structure of a flow rate sensor and a function of converting and displaying the detected flow rate into a swimming distance.

[0002]

2. Description of the Related Art Conventionally, in measuring swimming distance, it is basically necessary to count the number of round trips within a straight line course from the start point to the end point where the distance is measured in advance. Then this method is used exclusively.

[0003]

Although there has been a potential demand for measuring the swimming distance, in the prior art, the number of round trips in the straight course of the swimming pool is counted as described in the above paragraph 0002. It depended on the method. The present invention is not limited to the above-mentioned limited conditions, and an object of the present invention is to provide a swimming distance measuring device that realizes a measurement display of an actual swimming distance from an arbitrary start point to an end point without being limited to a straight course. To do.

[0004]

According to the present invention, in order to solve the problems, a swimmer is equipped with a measuring instrument having a combination of a flow rate sensor and a meter for displaying the detected flow rate as a swimming distance. To do.

[0005]

As described in paragraph 0004 above, a swimmer wears and uses a measuring instrument in which a flow rate sensor and a meter for converting and displaying a swimming distance are combined and used, so that the swimming between the arbitrary start point and the end point in the swimming pool can be performed. The distance can be measured. This is a static water system in swimming pools for swimming competitions and exercises, except for some running water swimming pools.
Although there is a slight exchange water flow for cleaning locally in this still water swimming pool, it is established from the fact that it is recognized as still water without problems in practice. In addition, the movement of the waves in the swimming pool is basically considered to be the vertical movement of water. Therefore, the swimming distance meter of the present invention does not detect the vertical movement of the water during the wearing method or It has a structure.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The swimming distance meter of the present invention will be described below with reference to the embodiments shown in the drawings.

FIG. 1 shows a mode in which the swim distance meter of the present invention is used by being attached to the waist of a swimmer. That is, the wearing belt B locks and attaches the terminal portion to the body by a surface fastener or the like. Reference numeral 1 is a body of the swimming rangefinder, and a display surface 2 is provided on the front side at a substantially central position of the wearing belt B. The display surface 2 is provided with a swimming distance display unit 3 of liquid crystal display and a reset switch 4. Reference numeral 5 is a flow rate sensor, 6A is its water intake, and 6B of drainage is provided on the symmetry plane.
The swimmer advances in the direction of the up arrow.

FIG. 2 is a front view showing the structure of an embodiment of an electronic swimming rangefinder according to the present invention. B is a wearing belt, and 1 is a body of the swimming rangefinder, and a swimmer swims in the direction of the up arrow. As a result, water is taken in from the water intake 6A provided in the flow rate sensor unit 5 to the drainage port 6B and is drained, so that the flow sensor 5 relatively moves through the water. In the still water pool, the passing flow rate of the flow rate sensor unit 5 is directly proportional to the swimming distance of the swimmer, that is, the swimming distance. From this main principle, the flow rate sensor unit 5
The swimming distance is measured by detecting the flow rate of water. When the passing motion of water is performed on the flow rate sensor unit 5 by the swimming motion, the rotor fin 7A and the rotor shaft 7B are coaxially rotated by the water flow. Detecting this amount of rotation means measuring the flow rate, that is, the swimming distance, for the reason described above. In the present electronic swimming rangefinder, a magnet 8 such as a permanent magnet is provided on the rotor fin 7A, and reed switches 9 are provided at positions where the lines of magnetic force of the magnet 8 can be sensed apart from each other. The reed switch 9 is electrically turned on / off by the passage of the magnet 8 to the reed switch 9 as the rotor fin 7A rotates, and the reed switch 9 is sent out as a detection pulse signal of a rotation amount, that is, a flow rate. . The detection pulse signal of the reed switch 9 is finally displayed as a swimming distance on the display surface 2 on the surface of the watertight structure 11 with the partition wall 10 interposed therebetween, by a liquid crystal display on the swimming separation display section 3. 4 is a reset switch,
It has a switch function for canceling and starting measurement. It should be noted that the rotor fin 7A and the rotor shaft 7B serve as an operating mechanism that coaxially rotates in one direction only in the forward direction in which water is taken from the intake port 6A to the drain port 6B and drained. It has a mechanism to prevent reverse rotation against the reverse flow of water. Reference numeral 12 is a rotor bearing portion, and 13 is a dust removing mesh. In addition, a power source unit using a small battery such as a button battery (not shown), an electronic circuit such as a detection circuit and an integrating circuit, and an electronic material are incorporated in the watertight structure unit 11.

The structure of the flow rate sensor unit 5 is not limited to the example shown in FIG. 2, but is generally used for measuring the liquid flow rate.
For example, a turbine type flow meter, a piston meter type flow meter, a disc meter type flow meter, or a differential pressure type flow rate, a flow rate meter, or the like having a structure capable of detecting the amount of water passing through the flow rate sensor unit 5 including the flow rate meter All are applicable.

FIG. 3 shows an embodiment of the circuit configuration of the electronic swimming rangefinder of the present invention, and 5 is the flow sensor as described in FIG. The detection pulse signals output from the flow rate sensor 5 and the reed switch 9 are sent to the calculation unit 20. A distance constant memory 21 is separately connected to the arithmetic unit 20. The set value of the distance constant memory 21 is determined in advance by actually measuring the distance traveled by the electronic swimming rangefinder per unit pulse in the detection pulse signal as a unique value. Thus, the detection pulse signal which is the output of the flow sensor 5 and the reed switch 9, the set value of the distance constant memory 21, and the signal of the arithmetic unit 20 whose distance is calculated by the counter are given to the integrating circuit 22 and integrated. Finally, the swimming distance is displayed on the display unit 3. The reset signal is sent by the reset switch 4 to the integrating circuit 22 and the swimming distance display section 3 to start and cancel the measurement.

The measurement and display items of the electronic swimming rangefinder are not limited to the display of the swimming distance as described in the above-mentioned item 0009 and FIG. It is also possible to measure exercise calories by the function of setting personal data, or to measure, calculate, and display daily, weekly, monthly comparison data such as swimming distance and swimming speed over time.

The swimming range finder according to the present invention includes the 0008 and 2 sections.
The swimming range finder can be constructed not only by the embodiment of the electronic swimming range finder illustrated in the drawing but also by a mechanical method. That is, as in the case of FIG. 2, for example, the flow rate passing through the flow rate sensor unit is detected as a rotation amount by the rotor fin and the rotor shaft that rotate coaxially, and the rotation amount is detected by a mechanical method using the rotation transmission shaft and the gear mechanism. It is transmitted to the watertight structure part that sandwiches, and further, by a mechanism such as a gear clock, the amount of rotation is converted into the swimming distance amount, and finally the swimming distance amount is digitally displayed by the number wheel. It is also possible to configure a rangefinder.

[0013]

As described above, in the swimming distance meter of the present invention, the flow sensor and the function of displaying the detected flow rate by further converting it into a swimming distance are used as a measuring instrument, and By wearing and using it, there is an effect that the swimming distance from an arbitrary start point to an end point can be easily measured.
