Abstract

PURPOSE:To count the number of steps accurately and enable to know accumulated number of steps in desired item, by detecting the number of steps by impressing of body weight during walking and displaying the total of each day, week, month and year. CONSTITUTION:When pressure of about a half of body weight is applied, a pressure sensor 11 senses this pressure and the number of steps in each day, week, month, year etc. is accumulated and stored in a memory circuit 12 by the signal. A clock circuit 13 resets the stored number of steps to zero at the end of each day, week, month and year. A selector circuit 14 selects memory of desired item in the memory circuit 12, and displays digitally on a display 15.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electronic pedometer, and more particularly to an electronic pedometer that is attached to shoes and measures the number of steps taken by applying body weight when walking.

Conventional pedometers are mechanical devices that are attached to the waist of a person walking and measure the number of steps taken using the vibrations generated when walking.

FIG. 1 is a top view of an example of a conventional pedometer.

A string 2 is attached to the pedometer 1, and the string 2 is passed through a belt and hung around the waist. The pedometer has a long hand 3 and a short hand 4, and each time you take a step, the long hand moves one scale clockwise, and one revolution of the long hand 3 equals 1000 steps.

The hour hand 4 moves at a rotational speed of 1/10 in accordance with the movement of the minute hand 3, and one revolution of the hour hand corresponds to 10,000 steps.

Conventional mechanical pedometers use vibrations to measure the number of steps taken, and are extremely sensitive. Therefore, even if a person wearing a pedometer on their waist bends or stretches their body while sitting in a chair, or twists their hips and causes the pedometer to vibrate, it will be detected and the vibration will be detected as if they were walking. It is measured as the number of steps taken.

Not only when you are sitting on a chair, but also when you are standing, if you apply vibration to the pedometer, it will count the number of steps you take. In this way, because conventional pedometers are highly sensitive,
On the other hand, it had the disadvantage of making the measurement of the number of steps inaccurate. In addition, conventional pedometers use a reset mechanism to return the needle to OK.
If you reset it daily, you can know the number of steps you have taken each day, but there is a problem when you want to know the number of steps you have taken each month or every month. This is because it becomes impossible to tell how many times both the long and short hands have rotated. This is because there is no storage device.

In this way, because conventional pedometers are highly sensitive, they often measure the number of steps inaccurately, and cannot remember the number of steps exceeding 10,000 steps, making it difficult to know the number of steps taken over a long period of time. There were drawbacks such as things that could not be done.

The present invention eliminates the above-mentioned drawbacks, measures walking only when body weight is applied during walking, and has a memory circuit having a large number of memory sections and a function for selectively displaying them, thereby providing accurate and desired information. The present invention provides an electronic pedometer that allows you to know the cumulative number of steps walked for an item.

The electronic pedometer of the present invention includes a pressure sensor that detects walking by applying body weight when walking, and a storage unit that accumulates and stores the number of steps taken based on a signal sent from the pressure sensor. and a memory circuit provided for each item such as daily, monthly, monthly, yearly, etc.;
a clock circuit that erases and resets the number of steps stored in the storage section at odd intervals such as monthly, monthly or yearly; a selection circuit that selects a desired storage section from the storage circuit; and a display device that displays the storage contents of the storage section selected by the selection circuit.

Next, embodiments of the present invention will be described using the drawings.

FIG. 2 is a perspective view of one embodiment of the present invention.

The electronic pedometer 10 of this embodiment is housed in a rectangular parallelepiped case, and the selection circuit 14 has a switch section left display device 1 on the side.
5 is displayed. The case is small enough to fit into the heel of a shoe.

FIG. 3 is a block diagram of one embodiment of the present invention.

The embodiment includes a pressure sensor 11 that detects walking by applying body weight when walking, a storage unit that accumulates and stores the number of steps taken each day based on a signal sent from the pressure sensor, and A memory circuit 12 comprising a memory section provided for each item such as monthly, monthly, yearly, etc., and a memory circuit 12 that measures time and stores it in the memory section at odd intervals such as daily, monthly, monthly, or yearly. a clock circuit 13 that erases and resets the number of steps taken; a selection circuit 14 that selects a desired storage section from the storage circuit 12; and a display that displays the memory contents of the storage section selected by the selection circuit 14. The device includes a device 15, a switch 16, and a power source 17.

FIG. 4 is a side view of the shoe to which the embodiment shown in FIG. 2 is attached.

An electronic pedometer 10 shown in FIG. 2 is fitted into the heel 21 of the shoe 20. If a cavity is made in the heel 21 and an electronic pedometer is inserted into it, when the shoes 20 become damaged or worn out, the electronic pedometer 10 can be taken out and inserted into new shoes. Good.

The pressure sensor 11 must be capable of measuring the number of steps taken when the weight is applied to the feet during walking. The number of steps taken by a person while sitting in a chair should not be counted as the number of steps. To do this, choose something that will only be sensed when a pressure equal to the size of your body weight is applied. Assuming that the average weight of an adult is about 9 in 60, when a pressure of about 9 is applied to the pressure sensor 11 [30],
Something that detects this is appropriate.

The memory circuit 12 has a large number of memory sections, such as daily, monthly, monthly, and yearly memory sections, and a memory section for cumulative numbers since the start of use. It is not necessary to provide these storage units for all items, but only for desired items. For example, the monthly storage section may be omitted. The memory circuit 12 stores the cumulative number of steps each time a signal from the pressure sensor 11 is sent.

The clock circuit 13 resets the corresponding number of steps stored in the memory circuit 12 to 0 for each change such as the change of the day, the change of the week, the change of the month, and the turn of the year.

The selection circuit 14 selects the storage section of the storage circuit 12 containing the item that the user wishes to view. The number of steps for this selected item is digitally displayed on the display device 15.

For example, if you want to know how many steps you have walked this month, select the monthly item and the display device 15 will display the number of steps you have taken from the beginning of this month to the time you selected.

Furthermore, when the shoes are worn out and replaced, the cumulative number of steps taken since the beginning of use can be displayed to determine the number of lines the shoes will last.

The power source 17 uses a battery. When the switch 16 is closed, use begins, but when the switch 16 is opened, all the number of steps stored in the memory circuit 12 returns to "0".

As explained in detail above, according to the present invention, the number of steps can be accurately measured, and not only daily, but also weekly, monthly,
This is highly effective because it provides an electronic pedometer that can store the number of steps taken by item, such as for each year.
