Abstract

PURPOSE:To set a variable suppressing force against a pendulum and to attain the accurate counting of number of steps by providing a movement suppressing means that suppresses the movement of the pendulum. CONSTITUTION:A pendulum 1, the base part of which is freely and rotatably supported, performs a reciprocal movement in synchronizing with steps. When the reciprocal movement of the pendulum 1 is detected by a detecting means 2 and the step is detected with the detecting means 2, the number of steps are counted with a counting means. A movement suppressing means 4 gives the variable suppressing force against the pendulum 1. By setting the suppressing force by the movement suppressing means 4 appropriately against the strength of the oscillation of the movement, the accurate counting of the number of steps can be obtained.

Description

[Detailed Description of the Invention] [Technical Field 1] The present invention relates to a pedometer, and more specifically, the suppressing force for suppressing the movement of the pendulum is variable in response to the strength of movement such as walking and running, thereby preventing chattering. Regarding the technology to be used.

[Background technology] Conventional gait counters resonate with the vibrations normally associated with walking, detect the reciprocating movement of a pendulum that is synchronized with walking, and count the number of steps or display walking distance. With objects, the strength of vibration varies depending on the walking motion, making the pendulum prone to chattering, making it impossible to measure accurately. In view of this point, the pendulum was equipped with a suppressing means for suppressing the reciprocating movement.
As is known from Publication No. 9985, in this case, the suppressing force of the suppressing means against the pendulum is constant, so it is effective for movement within a certain range, but when walking very slowly, There was a problem in that when running at full speed, the suppression means could not handle the problem, and the number of steps could not be detected, resulting in chattering. Furthermore, a filter circuit is known to remove /IX from the output signal of a detection means for detecting walking, as disclosed in Japanese Patent Publication No. 58-281320, but even in this case, chattering in the sensor is removed. still occurs, and a filter circuit is required, resulting in a complicated circuit.

[Object of the invention 1 The present invention has been made in view of such problems,
The purpose of this is to be able to adjust the suppressing force that suppresses the movement of the pendulum depending on the state of various movements such as walking, running, etc., to obtain the optimum suppressing force, and to avoid chattering. To provide a step counter that does not cause counting errors or non-counting.

DISCLOSURE OF THE INVENTION 1 The gait counter of the present invention comprises a pendulum 1 that rotatably supports a base and moves back and forth in synchronization with walking, a detection means 2 that detects the back and forth movement of the pendulum 1, and a detection means 2 that detects the back and forth movement of the pendulum 1; A counting means 3 for counting the number of steps when walking is detected by the means 2, and a movement suppressing means 4 for suppressing movement of the pendulum 1, the suppressing force of the movement suppressing means 4 on the pendulum 1 being variable. By configuring it in this way, the above object has been achieved.

That is, by making it possible to adjust the suppressing force that suppresses the movement of the pendulum 1, the suppressing force can be set to be appropriate for the strength of the vibration of the movement, and the number of steps can be accurately measured. That is, it is possible to prevent the pendulum 1 from chattering due to vibrations caused by walking.

Embodiments of the present invention will be described in detail below based on the drawings.

FIG. 3 is an internal structure diagram of the pedometer A of the present invention, in which a weight 7 as a heavy object 6 is provided at one end of the arm 5.
The pendulum 1 is constructed by providing a rotation shaft 8 on the opposite side. As shown in FIG. 4, the pendulum 1 acts as a sensor and vibrates in resonance with the walking motion of the human body, and as shown in FIG. is activated, this input is detected by a circuit section 12 provided in the main body, and the number of steps is displayed on the display section 3. Here, the arm 5 is pushed up by a push-up spring 14, which is an elastic member, and serves to return the weight 7, which is tilted downward, to its original position due to vibration. By the way, in the present invention, this spring 14 is connected to a support shaft 16 that is linked to an adjustment knob 15 as an external operator.
When the adjustment knob 15 is turned to the right in Fig. 3, the spring 14 is strongly pressed against the arm 5 of the pendulum 1, and the spring force acts strongly. It does not go down until the adjustment knob 15 is activated, and when the adjustment knob 15 is turned to the left, the spring force on the arm 5 is weakened so that even a weak vibration can cause the weight 7 to vibrate and activate the limit switch 10. As described above, in the present invention, the detection sensitivity of the pendulum 1, which depends on the intensity of exercise such as running or walking, can be changed steplessly (or stepwise). By the way, when the setting of the sensing sensitivity is changed in this way, it is necessary to confirm whether or not the number of steps is correctly and accurately measured at the set sensitivity of 1:. Therefore, when the buzzer switch 17 is turned on, the pendulum 1
A buzzer 18 as a notification means can be sounded in response to the operation of the limit switch 10. FIG. 1 is a perspective view of the pedometer A of the present invention, which includes a W14 adjustment knob 15, a buzzer switch 17, a reset switch 19 for resetting the number of steps displayed on the display g13, and a hook 20. It is designed so that it can be hooked and held on the waist of the human body. The adjustment knob 15 can be rotated by, for example, as shown in FIG. When the adjustment knob 15 is released, the protrusion 24 on the back side of the adjustment knob 15 is inserted and held in one of the many recesses 25 provided in the main body case by the spring force including the spring 14 wound around the support shaft 16. It is like that.

6 to 8 show other embodiments for changing the sensitivity setting of the pendulum 1. In FIG. 6, a serrated slit 21 is formed at the tip of the arm 5, The force acting on the spring 14 is changed by changing the position of the mounting shaft 22 of the weight 7, and the suppressing force increases as the weight 7 is moved closer to the rotation shaft 8, that is, as the point of force is moved closer to the fulcrum. 7th
In the figure, a serrated slit 21 as an example of a fixed part is formed on the base end side of the arm 5, and a spring 1 for pushing up is formed.
4, and the further the mounting position of the mounting shaft 23 is moved from the rotation shaft 8, the stronger the suppressing force becomes (in FIG. 8, the arm 5 has a support part as an example). This method changes the fulcrum of the pendulum 1 by forming a sawtooth-shaped slit 21 and changing the position of the rotation axis 8.
The further apart the mounting position of the rotation shaft 8 is from the base of the pendulum 1, the more
The suppressive force increases. The suppressing force 1lIlF5 increases when the vibrations are large, such as when running fast, and decreases when the vibrations are small, such as when walking slowly. By doing this, an appropriate suppressing force can be obtained depending on the state of exercise, and the number of steps can be accurately measured without chattering.

[Effects of the Invention 1] In short, the present invention provides a pendulum whose base is rotatably supported and moves back and forth in synchronization with walking, a detection means for detecting the back and forth movement of the pendulum, and a pendulum that detects the movement of the pendulum when walking. The present invention is equipped with a counting means for counting the number of steps by detecting the movement of the pendulum, and a movement suppressing means for suppressing the movement of the pendulum, and the suppressing force of the movement suppressing means on the pendulum is variable. Since the suppressing force can be adjusted to 'IIi', the suppressing force can be set to an appropriate suppressing force depending on the strength of the vibration of the movement, and the number of steps can be measured accurately.In other words, the pendulum will not chattering due to vibrations associated with walking. The advantage is that it can be done as follows.
