Description

[Detailed description of the invention] This invention describes the measurement conditions for measuring meters that measure the amount of exercise, such as pedometers, distance meters, and energy meters that are attached to the user's waist and have a pendulum that senses vibrations caused by exercise. This invention relates to an adjustment device.

Conventionally, a sensing device has a pendulum that is attached to the user's waist to sense vibrations caused by movements such as walking or running, a transmission device that transmits the vibrations of the pendulum to a display device, and a transmission device that transmits the vibrations of the pendulum to a display device. Examples of momentum measuring meters include a pedometer that displays the vibration of the pendulum as the number of steps, a distance meter that converts the number of steps into a distance traveled, and an exercise intensity (cal) that measures the amount of energy consumed per unit time. Momentum (cal) expressed as the product of /min) and exercise time
There was an energy meter etc. that converted it to .

However, the relationship between the user's walking and running speed and the acceleration acting on the waist is the straight line A in Figure 1.
The speed and energy consumption (cal/min) of walking, walking uphill, and running are proportional as shown in Figure 2, and are represented by straight lines B, C, and D, respectively.
3, the relationship between the acceleration at the waist and the amount of energy consumed per kg of body weight (cal/Kg/min), represented by the straight line E as shown in Figure 3, and the relationship between the acceleration at the waist and the amount of energy consumed per kg of body weight (cal/Kg/min), represented by the straight line F as shown in Figure 4. Lumbar acceleration and energy consumption per step (cal/
Kg/step), the amount of energy consumed is proportional to the speed of exercise, and the amount of energy consumed per step also differs depending on gender, age, weight, and height.

For this reason, in a momentum measuring meter having a pendulum that senses vibrations accompanying the user's exercise, it has been necessary to adjust the sensitivity of the pendulum in accordance with measurement conditions such as the user's exercise state and gender.

This invention was developed against the background of the above points, and its purpose is to adjust the amplitude of the pendulum and the spring force of the pendulum to be balanced depending on the measurement conditions such as the user or the type of exercise. Therefore, it is an object of the present invention to provide a measuring condition adjustment device for a momentum measuring meter, particularly a distance meter, which can display an accurate measured amount.

1. A worm gear 32 provided integrally with the ratchet gear 31, and a worm 33 provided on the transmission shaft 41 of the display device 4 that meshes with the worm gear 32.
and a ratchet gear 3 provided on the frame 11
It is composed of one reverse rotation prevention pawl 34.

The display device 4 includes a digital counter 42 that digitally displays the amount of rotation transmitted by the worm 33 via a transmission shaft 41, and displays the distance traveled.

The measurement condition adjustment device 5 includes an adjustment shaft 50 having male screws rotatably attached to the base 12 of the frame 11 at both ends, and a knob fixed to the lower end of the adjustment shaft 50 for rotating the adjustment shaft 50 from outside the casing 1. 5
1. A movable element 52 that is screwed into the male thread of the adjustment shaft 50 and reciprocates in the axial direction as the shaft 50 rotates; a lower limit stopper 53 of the pendulum 22 that is integrally provided with the movable element; An adjustment lever 55 is rotatably supported on the front plate 13 of the frame 11 and is engaged with a pin 54 of 52, and one end is connected to the pendulum 22.
A spring 56 is disposed in a loop shape with its other end locked to the other end of the lever 55, and a pendulum 22 is provided on the upper part of the base 12 of the frame 11.
and a sensitivity display indicator 58 provided at the tip of the lower limit stopper 53.

Further, the display device 4 is provided on the upper surface of the casing 1.
A window 15 and a reset button 16 correspond to the display section.
However, a display window 17 and a scale 18 for the indicator 58 are provided on one side, the knob 51 is provided on the bottom surface, and a condition table is provided on the front surface as a guideline for sensitivity adjustment to be selected by the user. 19 is provided corresponding to the scale 18. Furthermore, a mounting tool 6 is attached to the back of the casing 1 to be inserted into a user's band or the like.

Next, in order to use the distance meter configured as described above, the user first selects selection conditions from Table 19 displayed on the front of the casing 1 according to measurement conditions, such as stride length, exercise type, etc. Rotate the adjustment shaft 50 via the knob 51 and select the index 58 on the scale 1
Match 8.

As a result, the movable element 52 moves either up or down on the adjustment shaft 50 to adjust the distance between the upper limit stopper 57 and the lower limit stopper 53, and rotates the adjustment lever 55 to adjust the amount of deflection of the spring 56. . In this case, by appropriately setting the distance from the fulcrum to both ends of the adjustment lever 55 to form an expanding mechanism, it becomes easy to select various spring loads.

The position of this lower limit stopper 53 and the spring 56
The relationship between the amount of deflection and the amount of deflection of the spring 56 is that when the lower limit stopper 53 is located upward, the amount of deflection of the spring 56 is small, so the spring load is weak, and when the lower limit stopper 53 is located downward, the amount of deflection of the spring 56 is large. , the spring load becomes large, and the amount of deflection and the spring load are directly proportional.

Therefore, when the stride length or amount of momentum is small, the amplitude of the pendulum 22 is small, and when the stride length or amount of momentum is large, the amplitude of the pendulum 22 is large. Since the spacing of the pendulum 53 and the spring load of the spring 56 are proportional to these, the sensitivity of the pendulum 22 is adjusted accordingly.

When a rangefinder whose sensitivity has been adjusted in this way is attached to the user's lower back where vibrations are relatively stable, the vibrations caused by the user's movements such as walking and running will be absorbed by the pendulum 22. 21 and a spring 56 which is balanced with each other, the pendulum 22 is moved around the support shaft 14 by the upper and lower limit stoppers 5.
It reciprocates between 7 and 53. This reciprocating motion is transmitted to the ratchet gear 31 by a feed pawl 30 fixed to the pendulum 22, and the ratchet gear 31 rotates. The rotation of the ratchet gear 31 is converted by a speed reduction mechanism consisting of a worm gear 32 that rotates coaxially with the ratchet gear 31 and a worm 33 that meshes with the ratchet gear 31 and transmitted to the display device 4, and a value proportional to the movement distance is displayed on the digital counter 42. be done. The movement distance is obtained by converting the displayed value of the digital counter 42.

Note that the value displayed on the digital counter 42 of this distance meter is proportional to the number of steps if the above-mentioned selection conditions are the same, so it can be used as a pedometer by performing a predetermined conversion, or it can be calculated based on the gender and year of the user. Order,
Select selection conditions based on the other table 19 displayed on the front of the casing according to height, weight, exercise type, etc., and match the selection conditions with the corresponding scale 18 to obtain a value proportional to the energy consumption associated with exercise. It can be an energy meter displayed on a digital counter 42.

As described above, the present invention allows the adjustment of the interval between the upper and lower limit stoppers of the pendulum that senses the amount of movement of the user such as walking or running, and the adjustment of the spring load of the pendulum to be easily and simultaneously performed using the expansion mechanism. Therefore, using a single spring, a predetermined amount of amplitude and spring load can be obtained according to the amount of momentum, and the balance between the two can be easily and accurately achieved. can be adjusted in various ways depending on the measurement conditions.
