Description

Description: TECHNICAL FIELD The present invention relates to a pedometer, and more specifically, it suppresses chattering by freely changing the suppression force for suppressing the movement of the pendulum in accordance with the strength of movement such as walking and running. Regarding the technology to be tried.

BACKGROUND ART A conventional gait counter resonates with vibrations normally associated with walking, detects reciprocal movement of a pendulum synchronized with gait, and counts the number of steps or displays a walking distance. However, there is a problem that pendulum chattering easily occurs and accurate measurement cannot be performed because the intensity of vibration changes variously according to walking motion. In view of this point, Japanese Patent Application Laid-Open No. 59-109985 discloses a pendulum provided with a suppressing means for suppressing reciprocal movement.
In this case, since the restraint force of the restraint means against the pendulum is constant in this case, it is effective for exercise within a certain range, but when walking very slowly or at full speed. There was a problem that when the vehicle ran violently, the suppression means could not cope, the number of steps could not be detected, and chattering occurred. Further, a device in which noise in the output signal of the detection means for detecting walking is removed by a filter circuit is known from Japanese Patent Publication No. 58-28620, but even in this case, chattering in the sensor is still present. However, there is a problem that the circuit becomes complicated because a filter circuit is required.

[Object of the Invention] The present invention has been made in view of such problems,
According to the state of various movements such as walking and running, the purpose is that the suppression force that suppresses the movement of the pendulum can be adjusted, the optimum suppression force is obtained, and chattering does not occur. An object of the present invention is to provide a pedometer that does not count or fail to count.

DISCLOSURE OF THE INVENTION A walk counter of the present invention includes a pendulum 1 that rotatably supports a base and reciprocates in synchronization with walking, a detection unit 2 that detects reciprocal movement of the pendulum 1, and the detection. A counting unit 3 that counts the number of steps when the walking is detected by the unit 2 and a movement restraining unit 4 that restrains the movement of the pendulum 1 are provided, and the restraining force of the movement restraining unit 4 on the pendulum 1 is variable. The above-mentioned object is achieved by such a constitution. That is, by making it possible to adjust the restraining force for restraining the movement of the pendulum 1, it is possible to set the restraining force to an appropriate restraining force with respect to the intensity of the vibration of the motion, and it is possible to accurately measure the number of steps. That is, pendulum 1
It is possible to prevent chattering from occurring due to the vibrations of walking.

Embodiments of the present invention will be described in detail below with reference to the drawings.

FIG. 3 is an internal structure diagram of the pedometer A of the present invention, in which one end of the arm 5 is provided with a weight 7 as a weight 6 and the weight 7 is provided.
A rotator shaft 8 is provided on the opposite side to the pendulum 1. However, the lever pendulum 1 serves as a sensor and resonates with the walking motion of the human body to vibrate, and as shown in FIG. 4, the weight 7 operates the operating lever 11 of the limit switch 10 as an example of the detection switch 9 as the detection means 2. The circuit section 12 provided in the main body is operated to detect this input, and the number of steps can be displayed on the display section 13. Here, the arm 5 is pushed up by the spring 14 for pushing up as an elastic member, and it has a function of returning the weight 7 lowered downward by vibration to the original position. By the way, in the present invention, the spring 14 is attached to the support shaft 16 interlocking with the adjusting knob 15 as an external operating element, and the adjusting knob 15 is turned clockwise in FIG. 3 to press the spring 14 strongly against the arm 5 of the pendulum 1. If the vibration of the human body is not strong enough, the weight 7 does not fall until the limit switch 10 is actuated, and if the adjustment knob 15 is turned to the left, the spring force to the arm 5 becomes weak. Even if the vibration is weak, the weight 7 vibrates and the limit switch 10 can be operated. Thus, in the present invention, run,
The detection sensitivity of the pendulum 1 with respect to the intensity of exercise such as walking can be changed steplessly (stepwise).
By the way, when the sensing sensitivity is changed as described above, it is necessary to confirm whether or not the step sensitivity is correctly and accurately measured with the set sensitivity. Therefore, the buzzer switch 17
When the switch is turned on, the buzzer 18 as a notification means can be sounded according to the operation of the limit switch 10 by the pendulum 1. FIG. 1 is a perspective view of a pedometer A of the present invention. In addition to an adjusting knob 15, a buzzer switch 17, a reset switch 19 for resetting the number of steps displayed on the display unit 13 is provided, and a hooking unit 20 is further provided. Therefore, it can be hooked and held on the waist of the human body.
As a configuration for rotating the adjusting knob 15, as shown in FIG. 5, for example, the support shaft 16 is pulled out of the main body case together with the adjusting knob 15, and the adjusting knob 16 is rotated by a predetermined angle. Release the adjusting knob 15 to release the adjusting knob.
The protrusion 24 on the back surface side of 15 is fitted and held by one of the recesses 25 provided in the main body case by the spring force including the spring 14 portion wound around the support shaft 16.

6 to 8 show another embodiment in which the sensitivity setting of the pendulum 1 is changed. In FIG. 6, this tooth-shaped slit 21 is formed at the tip of the arm 5 and the weight 7 This is a system in which the acting force on the spring 14 is changed by changing the position of the mounting shaft 22, and the restraining force increases as the weight 7 is moved closer to the rotating shaft 8, that is, the force point is closer to the fulcrum. In FIG. 7, a sawtooth-shaped slit 21 as an example of a fixing portion is formed on the base end side of the arm 5, and the action point of the spring 14 for pushing up is changed. The farther the position is from the rotary shaft 8, the greater the restraining force. In FIG. 8, a saw-tooth slit 21 is formed on the arm 5 as an example of a supporting portion, and the fulcrum of the pendulum 1 is changed by changing the position of the rotating shaft 8. The farther the mounting position of the shaft 8 is from the base of the pendulum 1, the greater the restraining force. The adjustment of the restraint force increases the restraint force when the vibration such as running fast is large, and conversely reduces the restraint force when the vibration such as walking slowly is small. By doing this,
An appropriate restraining force can be obtained according to the exercise state, chattering does not occur, and the number of steps can be accurately measured.

[Effects of the Invention] In summary, according to the present invention, a pendulum that rotatably supports a base and that reciprocates in synchronization with walking, a detection unit that detects the reciprocating movement of the pendulum, and a walking by the detection unit are provided. Since the counting means for counting the number of steps by the detection and the movement restraining means for restraining the movement of the pendulum are provided and the restraining force of the movement restraining means with respect to the pendulum is variable, that is, the movement of the pendulum is restrained. Since the restraint force can be adjusted, the restraint force can be set to an appropriate restraint force with respect to the intensity of vibration caused by the type of motion, and accurate step count can be measured, that is, the pendulum does not cause chattering due to vibration accompanying walking. And has the advantage of being able to cope with changes in the type of exercise.
