Abstract

PURPOSE:To improve the accuracy of a number of steps detecting sensor and to measure correctly the number of steps by deviating the position of a read switch installed along the turning direction of a pendulum to the rotating direction side of the pendulum by a prescribed distance against the initially set position of the pendulum. CONSTITUTION:A reed switch 20 is turned along the turning direction of a pendulum and a line m-m in the direction of the radius of the pendulum (magnet 6) and the center line r-r of the reed switch 20 are deviated in advance to the turning direction of the pendulum 5 by a prescribed distance in such a way that the reed switch 20 is not operated by the magnet 6. When such arrangement is made, the number of steps can be measured correctly.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a step count detection sensor for a pedometer that detects the number of steps using a pendulum.

Conventional examples of this type of step count detection sensor include a mechanical type (Utility Model Application No. 1983-69380) or an electronic type (Utility Model Application No. 1987-69380).
-75364'j5' Publication) etc.

The mechanical type rotates a gear in response to the rotation of the pendulum and displays the pointer, but there is a problem in that the accuracy is poor because the scale is 100 paces or 100 meters as a distance display. 1st
Figures (a) and (b) show electronic step count detection sensors in which the magnet @ and the reed switch 09 are arranged differently. A magnet (C) is attached to the tip of the arm symbol whose base is rotatably supported, and the arm (force is supported in a straight line by a coil spring ■).The arm supported by this coil spring ( This method detects the number of vibrations of (a) by the number of operations of a reed switch placed opposite the magnet opening. ), the distance over which the reed switch 09 operates in the direction of rotation of the arm (a) is generally longer, and therefore the distance between the magnet (c) and the reed switch (a) in the initial position is longer. There is a problem in that the distance between the magnet 1) has to be long and a large amount of space is required.In Fig. 1(b), the magnet 1) is fixedly placed opposite the reed switch Q\). , the magnet (c) is in a position where the reed switch 09 is always operated, and a shielding plate (e) provided at the tip of the rotatable arm (a) is placed between the magnet (c) and the reed switch Q9. Reed switch only when moving 09 The present invention has been provided in view of the above-mentioned points, and it is an object of the present invention to provide a step count detection sensor that is small, highly accurate, and can accurately measure the number of steps.

Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings. In FIGS. 2 to 4, reference numeral ``l'' indicates a step count detection sensor disposed inside the pedometer to detect the number of steps, and FIG. 2 shows an exploded perspective view thereof. (2) is a flat box-shaped housing with an open upper surface, and a base plate (3) is later installed on the upper surface of a recess (4) formed in the housing (2). A positioning pin 7 (to) for positioning the main plate (3) and two wooden guide calipers (ll) for fixing the main plate (3) are protruded upward on the upper end surface of the base plate (2). (3
) is provided with an insertion hole (Iglf13) that is inserted and fitted into each of the above-mentioned screws (+ol). It is a pendulum, and a pendulum shaft (8) is press-fitted into one end of the pendulum (5), and the pendulum shaft (8) is fixed to the pendulum (5).
) is formed with a newly curved holding part 04) in a U-shape, and a magnet (6) is held and fixed in this holding part Q4). side θθ) is the pendulum shaft (5) press-fitted into the pendulum (5).
These are bosses that rotatably hold both ends of the base plate (8), and are integrally formed to protrude from the bottom surface of the recess (4) and the bottom surface of the base plate (3). (7) is a wire spring for returning the pendulum (5), and both ends thereof have hook portions (7a) (
7b), and hook and lock both hook parts (7a) and (7b) on the shafts of the screws (+6) and (16) that are press-fitted into the upper end surfaces of the pendulum (5) and the screw hole (2). That's how it is. That is, one biscuit (15) is fixed by press-fitting its shaft into a press-fit hole (22) drilled in the other end of the pendulum (5), and the external biscuit (15) is fixed by press-fitting its shaft into the press-fit hole (22) drilled in the other end of the pendulum (5), and the external biscuit (15) is fixed on the side wall of the housing (2). The wire spring (7) is fixed by being press-fitted into a press-fit hole (4) drilled on the side of the guide screw (1).Also, the approximate center of the wire spring (7) is connected to the end of the pendulum axis (+8+) of the pendulum (5). The pendulum (5) is located between the pendulum and the inner wall of the pendulum (2), and the wire spring (7) has an arcuate overall shape to increase the wire length. The outward biasing force of the wire spring (7) urges it toward the opposite section shown in Figure 2. This stopper has the function of suppressing the swing width of the pendulum (5) and mitigating the impact in the event of a collision.In other words, the pendulum is caused by the vertical vibration of the human body and the biasing force of the wire spring (7). Even if the pendulum (5) hits the stopper αη with force, it absorbs the impact and prevents the so-called bouncing, which prevents the pendulum (5) from swinging again and being undone by the reed switch. , the material of the stopper (+7) is made of a repulsive elastic material such as rubber or NBR rubber.The reed switch is placed opposite the magnet (6). 120j is placed in a concave 1s (2+1) with an open top at the end of the housing (2), and each time the pendulum (5) swings, the magnet (6) approaches.
Contacts open and close. Note that the step count secessor (1) is installed on the lower blade with the direction of the arrow shown in FIG. 2 being vertical.

That is, the direction of the N-8 magnetic field of the magnet (6) and the longitudinal direction of the reed switch (Liu) match, and the area A shown by the R line in the figure,
B is the area where the reed switch (20) is operated by the magnet (6).

In the initial position setting of the magnet (6), m-m and r-r are shifted because the M point of the magnet (6) is located in the off region and the pendulum (5) is moved due to the vertical movement of the human body. When it rotates downward, point M enters the region and the reed switch (2o) operates for the first time. Further, even when the magnet (6) rotates downward and is located at the lowest blade, the M point of the magnet (6) is located in the oscillating region due to the stopper θ force. Then, when the magnet (6) returns to its original position, the reed switch (20) is turned off again. In this way, m-m and r-
In other words, the reed switch (20) is installed offset.
