Description

[Detailed explanation of the idea] This invention relates to the improvement of indoor runners.

Conventionally, indoor runners simply count the number of steps you take when you run on a foot mat and display them on a display, but this method has the problem of being too crude when evaluating the improvement in physical fitness caused by running. be.

In other words, this device is excellent in terms of determining running speed and stamina, as it allows you to see how many steps you took before getting tired during your running motion, or how many steps you were able to record in a certain amount of time, but it also shows things like jumping ability, etc. There was a problem in terms of judgment, and it was not possible to comprehensively judge the improvement of physical fitness.

This invention has been made in view of these points, and the purpose is to provide an indoor running device that allows for a more comprehensive assessment of the improvement in physical strength due to running motions, and that can be used for multiple purposes.

Hereinafter, embodiments of this invention will be described with reference to the drawings.

1 in the figure is a foot mat, and this foot mat 1 has a built-in pressure-sensitive switch 2.

The pressure sensitive switch 2 is, for example, of a contact type, and is closed when a load is applied to the mat 1, and opened when no load is applied.

The pressure-sensitive switch 2 is shown as one in the figure for simplicity, but in reality, it is provided at the left and right foot positions, respectively.

The number of opening/closing operations of the pressure-sensitive switch 2, that is, the number of steps taken by the foot, is counted by a first counting circuit 3 and displayed numerically on a display 4.

That is, the first counting circuit 3 forms a running control circuit.

Further, 5 in the figure is a clock pulse oscillator, and the clock pulses generated from this oscillator 5 are counted by a second counting circuit 7 via a gate circuit 6.

The gate circuit 6 is energized by the pressure-sensitive switch 2, and while the pressure-sensitive switch 2 is open, its gate is open to allow the clock pulse from the clock pulse oscillator 5 to pass.

Then, based on the count counted by the second counting circuit 7, the multiplication circuit 8 calculates the height of the jump, and the result is displayed numerically on the display 4.

That is, the second counting circuit 7 and the multiplication circuit 8 form a control circuit for measuring the jump height.

It is possible to select whether the foot mat 1 and the display 4 are to be used for running or for measuring jumping height by a pair of mutually interlocking selection switches 9a and 9b. .

In other words, one selection switch 9a is connected to the pressure sensitive switch 2.
and the input section of the first counting circuit 3 and the gate control section of the gate circuit 6, and the other selection switch 9b is inserted between the display 4, the output section of the first counting circuit 3, and the gate control section of the multiplication circuit 8. It is inserted between the output section and the output section.

Then, the opening/closing signal of the pressure-sensitive switch 2 is supplied to the input section of the first counting circuit 3 through the fixed contact a of one of the selection switches 9a, and is also supplied to the gate circuit 6 through the fixed contact of the one selection switch 9a. The power is supplied to the gate control section of the

Further, the output of the first counting circuit 3 is supplied to the display 4 through the fixed contact a of the other selection switch 9b, and the output of the multiplication circuit 8 is supplied to the display 4 through the fixed contact a of the other selection switch 9b. We are trying to supply it to

Both selection switches 9a and 9b have fixed contacts a, a, l)
and b open and close in synchronization with each other.

The multiplier circuit 8 detects the open time of the pressure-sensitive switch 2, that is, the flight time t of the jump from the count value of the second counting circuit 7, and calculates the height of the jump by calculating 1225t2 from the flight time t. It is calculated in millimeters and supplied to the display 4.

In other words, when an object is thrown directly upward against gravity, the distance between its flight time t and the height h at which the object reaches its highest position is 2- h=-t -1225t tttxr----
--°(1) (where g is gravitational acceleration of 9800mm/
It is known that the relationship 5eC2) can be obtained.

On the other hand, the number of pulses C counted by the second counting circuit 7 during the flight time t is C=ft (2) (where f is the oscillation frequency of the clock pulse oscillator) The sojourn time t can be determined from the relationship C/f.

Therefore, from the oscillation frequency f of the clock pulse oscillator 5 and the count value C of the second counting circuit 7, the multiplier circuit 8 calculates h = 1225 C2/ f 2 (
3) can be performed to calculate the jump height h.

Note that each of the counting circuits 3 and 7 is reset by a reset signal R generated by manual operation, for example.

In such a configuration, first, the user runs on the foot mat 1 with the selection switches 9a and 9b set to the fixed contact a side.

The number of steps taken during running is counted by the first counting circuit 3 and displayed on the display 4.

Therefore, by setting a running time in advance, it is possible to measure how many steps the user has completed within that time, or in other words, how much the running speed has been increased.

You can also run until you get tired and measure how many steps you have taken.

These measurement results can tell you how much running speed you have gained and how much stamina you have gained.

Next, the selection switches 9a and 9b are set to the fixed contact side, respectively, and a vertical jump is performed on the foot mat 1.

In response to the opening operation of the pressure-sensitive switch 2, the second counting circuit 7 counts the clock pulses of the clock pulse oscillator 5. Accordingly, the multiplier circuit 8 calculates the height h of the jump, and the display 4 respectively Display.

Therefore, you can know how much jumping power you have gained.

In this way, you can see not only your endurance and running speed, but also the extent to which you have improved your jumping ability, making it possible to make a more comprehensive assessment of your physical strength improvement.

Furthermore, this device not only measures the improvement in physical strength due to running, but also can be used for jumping purposes separately from running, allowing it to be used for multiple purposes.

Furthermore, since the foot mat and display are shared for running and jumping height measurement, the configuration is simple and inexpensive.

In the above embodiments, a pressure sensitive switch using a contact type was described, but the present invention is not limited to this. For example, a non-contact type such as a semiconductor pressure sensor or a strain gauge may be used. It may be.

As detailed above, according to this invention, it is possible to measure running endurance and running speed as well as jumping power using a common pressure-sensitive switch and display, making it possible to more comprehensively improve physical fitness through running. Moreover, since the jumping force measurement can be performed separately from the running motion, it is possible to provide an indoor running device that can be used for multiple purposes.
