Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention mainly relates to a human exercise amount measuring device.

[Conventional technology]

Conventional devices for measuring the amount of human exercise include so-called pedometers, which measure the number of steps taken when walking or running, and momentum meters, which detect the acceleration of body movements. The pendulum is oscillated each time it walks or runs, and this oscillation is transmitted to the ratchet teeth via a feed pawl, or a magnet is provided at the tip of the pendulum and this is detected by a reed switch or magnetic sensor. In addition, the latter measures the acceleration that occurs when the body moves using a strain gauge or piezoelectric element, extracts the amount of movement of a magnet supported by a spring in an induction coil as an induced electromotive force, or uses an optical slit to maintain a constant Sliders provided at intervals are housed in a cylinder, and the movement of the optical slits of the sliders is detected as a pulse amount by a light emitting diode and a phototransistor placed in the middle of the cylinder. I was doing a lot of things.

[The problem that the idea attempts to solve]

However, many of these mechanisms have relatively complex structures, use expensive parts, or process more information than necessary.

The inventors of the present invention found that the daily amount of exercise in daily life is mainly due to the amount of vertical movement in walking, running, climbing, bending, stretching, jumping, etc., which is considered to account for the majority of the amount of exercise in daily activities, compared to the amount of lateral movement. ,
It was found that this accounted for a large proportion of the population.

Therefore, the purpose of the present invention is to provide a momentum measuring device that has a simple mechanism and can measure reliably by detecting and measuring the vertical vibration acceleration caused by this vertical motion. There is a particular thing.

[Means to solve the problem]

In order to achieve such a purpose, the momentum measuring device of the present invention uses a plate-shaped plate with a plurality of teeth carved on the front edge of the distal end, which is wider than the base end and is pivoted on the substrate by a support shaft. a pendulum; a suspension spring that is suspended so that the center line of the pendulum is substantially horizontal; an upper limit stopper and a lower limit stopper that regulate the amplitude within a predetermined range; and a magnetic sensor that faces the tip of the pendulum and detects the number of teeth of the tip that swings with the amplitude of the pendulum and converts it into an electrical signal. , and a display device that inputs this electrical signal and displays the amount of exercise.

〔Example〕

The illustrated embodiment will be described below.

A bracket 3 is fixed to the front left side of the board 1 with screws 2, 2, and the base end of a plate-shaped pendulum 5 is pivotally supported on a support shaft 4 whose both ends are supported by the board 1 and the bracket 3. has been done.

The tip end 5a of the pendulum 5 is wider than the base end, and a plurality of teeth 5b are engraved on the arcuate front edge of the tip end 5a.

The pendulum 5 is suspended by a suspension spring 6 stretched between one side 5c of the tip 5a and the substrate 1 so that the center line of the pendulum 5 is approximately horizontal. The distal end portion 5a is supported so as to be swingable in the vertical direction with vibration acceleration in the vertical direction.

The front surface of the substrate 1 at the upper and lower positions of the locus of the tip portion 5a due to the swinging of the pendulum 5 is suspended by a suspension spring 6 with the center line deviated so as to be approximately horizontal, so that the front surface of the substrate 1 is suspended upwardly. An upper limit stopper 7 that abuts one side 5c of the distal end 5a and a lower limit stopper 8 that abuts the other side 5d located below are fixedly provided to regulate the amplitude of the pendulum 5 within a predetermined range.

In addition, a magnetic sensor 9 is provided on the front right side of the board 1.
are fixedly provided opposite to the teeth 5b of the tip portion 5a. The magnetic sensor 9 detects the number of teeth of the tip 5a that swings with the amplitude of the pendulum 5 and converts it into an electrical signal. The waveform is shaped in step 10, and arithmetic processing is performed in the integration integrated circuit 11 to which setting conditions such as gender, age, weight, height, etc. are added.
Calories are displayed in 2.

The board 1 and the pendulum 5, suspension spring 6, upper and lower limit stoppers 7 and 8, magnetic sensor 9, waveform shaping circuit 10, and integration integrated circuit 11 provided on the board 1 are housed in a case 13. be done.

On the surface of the case 13, gender, age, weight,
Conditions such as height are determined numerically, and integration integrated circuit 1
A condition setting table 14 is provided as a guide for setting the condition to 1, and the number selected in the condition setting table 14 is inputted with the setting switch 15, and the number is displayed on the condition setting display window 16. Further, the display 12 and reset switch 17 are provided on the top surface of the case 13, and a hook 18 for hooking onto a band or the like is provided on the back surface of the case 13.

Next, to explain the operation of the above device, press the reset switch 17 to make the display 12 display zero, and then set the number selected in the condition setting table 14.
The setting switch 15 is used to input the number to the integration integrated circuit 11, and the number is displayed on the condition setting display window 16.

When the hook 18 is hooked onto a band and worn on the waist or the like and exercised, vibration acceleration in the vertical direction is generated in proportion to the amount of momentum, thereby causing the pendulum 5 to be elastically supported by the suspension spring 6. As shown in FIGS. 1 to 3, it swings in the vertical direction.

When the pendulum 5 swings vertically, the magnetic sensor 9
detects the changing number of teeth on the tip 5a with a magnetic sensor 9, converts it into an electrical signal, inputs it to a waveform shaping circuit 10, where the waveform is shaped, and the number of pulses is sent to an integration integrated circuit. 11.

The input pulse number and the previously set setting conditions are processed by the integration integrated circuit 11,
Calories are displayed on the display 12.

In the above embodiment, the pendulum 5 is approximately T-shaped,
Although it has a shape with teeth at the tip, the present invention
It is not limited to this, and it is also possible to use a fan-shaped gear or the like.

[Effect of idea]

Focusing on the fact that human momentum is mainly in the vertical direction, the present invention uses a plate-shaped plate with multiple teeth carved into the front edge of the tip, which is wider than the base end and is supported by a support shaft on the base plate. The pendulum is suspended with a suspension spring so that the center line of the pendulum is approximately horizontal, and the tip is supported so as to be able to swing vertically with vibration acceleration in the vertical direction. and a lower limit stopper to regulate the amplitude of the pendulum within a predetermined range, and a magnetic sensor facing the tip of the pendulum detects the number of teeth at the tip swinging with the amplitude of the pendulum and converts it into an electrical signal.
Moreover, since it is equipped with a display that inputs this electrical signal and displays the amount of exercise, it is possible to accurately detect the amount of calories consumed by exercise with a simple mechanism, and
Since the vibration of the pendulum is detected, even if the measuring device is tilted to some extent, sliding friction does not occur on the pendulum, allowing accurate vibration and detection. In addition, since a plate-shaped pendulum is used, the thickness of the measuring device can be reduced, and the pendulum is suspended from a suspension spring with its center line being approximately horizontal, making it easy to adjust the sensitivity. Easy and highly sensitive detection is possible without the need to consider sliding friction.
