Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field 1] The present invention relates to a pedometer that detects vertical movement of a human body and displays a decimal total.

[Background Art 1 Conventionally, a pedometer that displays the number of steps by detecting the vertical movement associated with walking has a hook part 52 provided on the back of a pedometer main body 51 that is attached to a belt 53 or clothing, as shown in FIG. It's stopped,
Since the display section 54 faces forward, there is a problem in that in order to view the display, the user must hold the pedometer main body 51 and face the display section 54 upward, which is inconvenient.

Therefore, as shown in FIG. 17, when the hook part 56 of the pedometer main body 55 is attached to the waist belt 53, etc., the display part 57 is designed so that the display can be easily seen even while walking.
However, it is necessary to make the decimal meter main body 55 as thin as possible so that it does not interfere with exercise when attached to the waist.
The display section 57 is small and difficult to see, and since the display section 57 is exposed to the outside, there is a risk that the display section 57 may be damaged. Further, since the display section 57 is exposed to the outside, it tends to attract attention from people other than the recipient, and there is a problem that, for example, it becomes difficult to wear it on the way to work.

[Object of the Invention] The present invention has been provided in view of the above-mentioned points, and an object of the present invention is to provide a pedometer that has a large display section to make the display easy to see, and also protects the display section. It is something to do.

[Disclosure of the Invention 1 (Structure)] The present invention includes a main body casing in which a display section is exposed on the front, a cover rotatably attached to the lower end of the main body casing to cover the front surface of the main body casing, and a 1 below! The U symbol is that it is equipped with a useful hook.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings. first,
The pedometer of this embodiment is constructed as shown below or as follows. In other words, this pedometer is a reed switch that operates by the movement of a magnet attached to the free end of a pendulum that vibrates as the human body moves up and down. A counter provided on a printed board receives a signal from a walking detection sensor provided with a gate, and the signal is counted by a counter provided on a printed board and displayed on a display section formed of a liquid crystal panel or the like.

Next, the gist of the present invention will be explained with reference to FIGS. 1 to 5.

The pedometer main body 1 is formed from a main body casing 2 and a cover 3 covering the main body casing 2. A scratching section 6 consisting of an erase button 4, a switch 5 for switching between walking and running, and a display section 7 for displaying the number of steps, etc. are provided on the upper surface of the main body casing 2, and these scratching section 6 and display section 7 are protected. In order to do this, a cover 3 is attached to cover the upper surface of the main casing 2, as shown in FIG. 3, and can be opened and closed about rotating parts 8 on both sides of the base of the cover 3. Usually, the convex part 1 of the hook part 9 of the main casing 2
0 is fitted into a recess 11 formed at the end of the cover 3 and closed as shown in FIG. An abbreviated hook 12 is integrally formed on the back surface of the cover 3, and the hook 12 is used by being hooked onto a belt 13 or the like as shown in FIG. A stopper portion 14 is formed on the base end surface of the main body casing 2, as shown in FIG. 5(a). A stopper part 15 is also formed on the base end surface of the cover 3 in correspondence with the stopper part 14. When the cover 3 is closed, the stopper part 14.15 is as shown in FIG. 5(a). is formed at an angle of 90 degrees, and when the cover 3 is opened, as shown in FIG. 5 (1,),
When the cover 3 is opened 90 degrees, the stopper part 1 of the cover 3
5 hits the stopper part 14 of the main casing 2,
The cover 3 is designed not to open more than 90 degrees.

Therefore, as shown in FIG. 1, when you want to see the step count display, just pinch the hook part 9 of the main body casing 2 and open it. Even when the device is attached to the device, the display is at an easy-to-see angle, making it easy to read.

Next, the structure will be explained. FIGS. 6 and 7 show the main parts of a walking detection sensor 16 that detects walking by detecting vibrations of the human body accompanying walking. A pendulum 18 is supported by a shaft 19 on a U-shaped base 17. A small magnet 20 is attached to the tip of the pendulum 18. base 17 leg 1
1s17a, the reed switch 21 is placed close to the magnet 20.
Gotori! ), and the pendulum 18 is supported by a spring 22 so as to maintain a horizontal posture without acceleration, and the spring 22 is attached to a support bin 23 of the base 17.
and a support pin 24 at the tip of the pendulum 18. Stoppers 25 are provided on both inner sides of the base 17 to prevent the pendulum 18 from swinging too much. Walking detection sensor 16
is arranged at the bottom of the main body casing 2 as shown in Fig. ttF17, and a printed board 27 is arranged above the walking detection sensor 16, and a display section 7 is connected to the upper surface side of this printed board 27 via a connector rubber 28. is installed.

These are housed in the main casing 2 together with the battery 26, and are attached to the person's waist with the arrow direction in FIG. On the other hand, since the pendulum 18 swings up and down, the magnet 20 attached to the tip of the pendulum 18 approaches or moves away from the reed switch 21, and the reed switch 21 opens and closes. The opening/closing of this reed switch 21 is used as a detection signal to connect the dead band circuit 3 as shown in FIG.
1, the detection signal is input to the counter section 32, the detection signal is counted by the counter section 32, and the counted value is appropriately displayed on the display g7. Note that the dead band circuit 31 will be described later.

Here, V, since the measurer sets the changeover switch 5 provided on the main body casing 2 according to walking or running, separate unfavorable zone times rJ are provided for walking and running. . Dead band circuit 31, counter section 3
Since the second component can be constructed from a small electronic circuit, it is actually integrated with the walking detection sensor 1G and housed in the same main body casing 2. Note that other methods such as detecting the vibration of a magnet using a coil or detecting the distortion of a pendulum using a strain gauge may also be used as the means for detecting the vibration.

FIG. 9 shows another embodiment, in which the cover 391
11 is provided with a walking detection sensor 16 consisting of a pendulum 18, a magnet 2(), a reed switch 21, etc., and a display 11'57 is provided on the main body casing 2. Therefore, even if the cover 3 of the pedometer main body 1 is opened and the main casing 2 with the display section 7 is held horizontally, the direction of vibration of the pendulum 18 is always vertical and does not change, so the walking movement The device operates normally, and the number of steps counted on the display section 7 of the main body casing 2 can be viewed while walking. In other words, accurate counts can be obtained even when walking while looking at the display.

By the way, Figure 10 shows the relationship between the vertical acceleration associated with walking and the operations of the walking detection sensor 16 and the dead zone circuit 31. FIG. 10(a) shows the change in acceleration G associated with normal walking or running, and FIG. 10(b) shows the opening/closing of the reed switch 21 at that time, and therefore the state of the detection signal S obtained thereby. -small pitch T
One pulse is obtained as the detection signal S for each time.

However, if you walk in such a way that there are two peaks of acceleration in one pitch T, as shown in (e) in the same figure, the detection signal S will change to (
As shown in d), one pitch T includes two pulses p, , p2, so if this were counted as is, the number would be higher than the actual number of steps. (e) of the same figure shows a hold signal V that lasts for a fixed time period T0, which is shorter than the pitch T. This hold signal ■ is generated in the dead band circuit 31 in response to the first pulse P within the pitch T, and the hold signal ■ The second pulse P? which arrives during the duration of P? is prevented from being sent to the counter section 32.

Figure fIS8 shows a specific circuit diagram of the dead band circuit 31, which includes a resistor R11, a diode D1, an inverter I, .
r2, capacitors C, , C, etc. FIG. 11 shows voltage waveforms at various parts of the dead band circuit 31. The voltage waveform at one point in Figure 8 is the detection signal waveform from the walking detection sensor 16, as shown in Figure 11 (,), where Pl is a normal pulse and P2 is an extra pulse that causes an error. It is. This waveform is inverted by inverter ■1 to obtain the waveform at point b shown in Fig. 11(b), and resistor R
,, When added to an integrating circuit consisting of a CR circuit consisting of a capacitor C4 or C2 and a diode D1 connected in parallel to a resistor R3, the waveform at point C becomes as shown in Fig. 11(e), so this waveform can be expressed as When the inverter 2 is used to clip and invert the signal at a constant reference voltage, the waveforms shown in FIG. 11(d) are obtained at d and α.

That is, pulse P due to a normal detection signal waveform.

is the pulse width T. However, if the waveform includes an extra pulse P, it is converted to a pulse width T0+α and sent to the counter unit 32 as one pulse. , pulse P2
is prevented from being sent to the counter section 32 as a new pulse number 1S.

When walking, the hold time To is determined by the time constant of the resistor R3 and the capacitor CI, and is usually set to about 0.4 seconds. When running, To is determined by the resistor R3 and the time constant of the capacitor CI.
1 and capacitor C2, and if T0 is selected to be approximately 0.25 seconds, most errors can be prevented.

Therefore, since the dead zone circuit 31, which blocks new signal input to the counter section 32 for a certain period of time in response to the detection signal from the walking detection sensor 16 in response to walking or running motions, is variable with respect to walking or running, abnormal Even if an extra signal is output from the walking detection sensor 16 due to vertical movement, it will not be counted (this means that even if the sensitivity is increased, a pedometer with small errors and accurate counts can be obtained. be.

[Effects of the Invention 1] As described above, the present invention provides a pedometer that is equipped with a walking detection sensor that detects walking by detecting vibrations of the human body accompanying walking, and that displays the number of steps on a display unit based on the output of this walking detection sensor. A main body casing in which the display section is exposed on the front side, a cover rotatably attached to the lower end of the main body casing to cover the front surface of the main body casing, and a hook extending downward from the back surface of the cover. Since the pedometer body is made thicker than necessary, unlike conventional pedometers, the display part can be made large and easy to see. Also, since the display part is protected by the cover, there is no risk of damage. Furthermore, by covering the main body casing with a cover, the display section is not normally visible, so it does not attract attention from anyone other than the person being measured (and can be worn discreetly). This has the following effect.
