JPH0325308A - State variation detecting device for body - Google Patents

Abstract

PURPOSE:To move a couple of balls corresponding to the body whatever direction the body slants in and to detect the state variation by supporting a detection member rotatably in all directions. CONSTITUTION:When a solenoid 12 is fed with electricity while the base 1 for the body is horizontal, a housing 7 is released from being fixed, so the housing 7 becomes perpendicular and its axis C1 is aligned with a perpendicular line C2. Then when the solenoid 12 is stopped from being fed, a lever 15 moves to a position shown by an alternate long and two short dashes line with the reaction force of a spring 16, so the housing 7 is pressed by the lever 15 and fixed, so that the setting is completed. At this time, light from a photosensor 10 is reflected by a steel ball 9, so the perpendicular state of the housing 7 is detected. Thus, when the installed housing 7 is slanted, the steel ball 9 rotates on a rolling plate 8 to leave the axis C1. The light from the photosensor 10 is not reflected by the steel ball 9, so the inclination of the base 1 is detected.

is consistent with

Next, the operation will be explained.

Figure 1 (a3 shows the setting state when the base 1 of the object is horizontal. When the solenoid 12 is energized, the fixation of the housing 7 is released, so the housing 7 becomes vertical, and the axis C1 is vertical. nc2. Then, when the solenoid 12 is de-energized, the repulsive force of the spring 16 moves the lever 15 to the position indicated by the two-dot chain line, so the housing 7 is pressed and fixed by the lever 15, completing the setting. At this time, since the light from the optical sensor 10 is reflected by the steel ball 9, it is detected that the casing 7 is in a leaden state.

When the casing 7 installed in this manner is tilted as shown in FIG. 2, the casing 7 is tilted and the steel balls 9 rotate on the rolling plate 8 and move away from the axis C1. Therefore, since the light from the light beam 10 is not reflected by the steel ball 9, it is detected that the base 81 is tilted.

FIG. 3 shows an example in which the base 1 is inclined from the beginning. In this figure, although the base 1 is tilted, the housing 7 is vertical. In this case as well, when the lever 15 moves to the position shown by the two-dot chain line and presses the housing 7 to make the base horizontal as shown in FIG. 4, the housing 7 also moves together with the base 1, so the steel ball 9 It is detected that the object is rolling and the state of the object has changed.

FIG. 5 is a side sectional view showing another embodiment of the present invention, in which the fixing means is provided below all the detection members. In the figure, the first
The same reference numerals as in the drawings indicate the same parts, 21 is the base, 22 is the case fixed to the top of the base 21, 23 is the entire detection member, 24 is the housing, and 25 is the housing 24. It is an inclined surface formed inside, and is formed so as to descend from the periphery toward the center. 26 is a steel ball, 27 is a light emitting element, 28 is a light receiving element, 29 is a fixing means, 3o is a solenoid, 31 is a plunger, 32 is an engagement piece attached to the plano jar 31, 33 is a lever, and 34 is an engagement piece. synapse,
35 is a spring, 36 is a fulcrum, and 37 is a spring.

FIG. 5 shows the setting state when the base 1 is horizontal, and when the engagement piece 32 releases the pressure on the engagement protrusion 34 by energizing the solenoid 30 and reaches the position indicated by the two-dot chain line. , the lever 33 descends to the position indicated by the two-dot chain line, so
The housing 24 is in a vertical state, and the axis C1 and the vertical axis 8C2 coincide. After that, I was told to de-energize solenoid 30.
The repulsive force of the spring 35 causes the engagement piece 32 to push the engagement protrusion 34 and push up the bar 33, thereby fixing the housing 24 and completing the setting.

At this time, since the light emitted from the light emitting element 27 is blocked by the steel ball 26, the light is not received by the light receiving element 28 and it is detected that the casing 24 is in a vertical state.

In this way, when the set housing 24 is tilted, the steel ball 2
6 is transferred to the position indicated by the two-dot chain line, so that the light emitted from the light emitting element 27 is no longer blocked by the steel ball 26, and is received by the light receiving element 28, thereby detecting that the housing 24 is tilted.

FIG. 6 shows an example in which the base 21 is inclined from the beginning. In this figure, a base 21, a case 22
Even if the housing 24 is tilted, the housing 24 remains vertical. When the base 21 is made horizontal from this state, the steel ball 26 rolls, and it is detected that the state of the object has changed.

FIG. 7 is a circuit diagram showing one embodiment of the present invention.
This corresponds to the embodiment shown in the figure. In this diagram, R1-R12 are resistors, DI-D is a diode, C-C is a capacitor, Q1-Q3 is a transistor, INVI-INV
3 is inverter, NG is Noah game 1, A is relay a
is the contact point, and B is the relay. , blb2 is the contact point, CL
is a horn.

Next, the operation will be explained.

In this diagram, SW is a car switch that is always on during driving, and 1/Lannostar Q1 is conductive and relay A is operating, so its contact a is off and the circuit below contact a is Power is not supplied to the

Next, when the driver gets out of the car, the car switch S
When W is turned off, after 2 to 30 seconds have elapsed until the charge in the cocidenser C1 is discharged by the resistor R2, the 1-range star Q1 is turned off, relay A is also turned off, and contact a is turned off.
Close it. In other words, if the device for detecting changes in the state of an object according to the present invention is activated immediately after turning off the car switch SW, the car may tilt due to the weight of the person and an alarm may not be issued. It has a delay of .

By turning on contact a, the power supply voltage becomes ■. . is applied to each part, but only the surge potential passes through the condenser C2 and is applied to the inha 9.
After 1 N V 1, I N V 2,
11'' level and turns on transistor Q2.

As a result, the noid 30 operates for a short time, releases the fixation of the detection member 23 as described above, and
to be able to assume a vertical state. At the same time, the buzzer BZ sounds to notify that the setting of the article condition change detection device of the present invention has been performed. The solenoid 30 operates only during the period when the surge current flows through the capacitor C2, and when the steady state is reached, the @m current is blocked by the capacitor C2, so the transistor Q2 is turned off and the solenoid 30 is fixed again. be done. That is, even if the automobile is stopped on a slope, the detection member 23 is set vertically, and the steel ball 26 is also automatically set at the center position of the rolling plate 8. In other words, between the light emitting element 27 and the light receiving element 28, the steel ball 2
6, the light-receiving element 28 is off, capacitors C3 and C4 are charged to the "H" level, and the inverter INV3 lowers the 1 "HI1 level" on the capacitor C4 side to "L" level, resulting in no game]- The output of NG is at the "l L l" level, and the l transistor Q3 remains off.

In this state, when the car tilts, the steel balls 26 roll,
Therefore, light shielding between the light emitting element 27 and the light receiving element 28 is removed. Therefore, the light receiving element 28 is turned on, and the charge in the capacitor C3 is discharged through the resistor R, and the discharge reaches a predetermined "L" level (4 to 5 seconds).
On the other hand, the charge in the capacitor C4 is also discharged via the resistor R, but since the discharge time constant of this side is set larger than that of the capacitor C (for example, 30 seconds), the light receiving element 28
For about 30 seconds after 4 to 5 seconds have passed since the switch was turned on, an output is output from Noah Game 1/NG, which turns on transistor Q3, operates relay B, and turns on contact b1, causing a crackling sound. CL Sounds. At this time, contact b
Since relay B is also turned on, relay B is temporarily restored, but this also turns off contacts bI and b2, so that the relay B is turned on again. −
-B works. In this way, contacts b and b2 repeat on and off, and the horn CL sounds intermittently.If the driver returns and turns the car switch switch to off,
Relay A is turned on, contact a is opened, and the reset I is complete.
・It becomes.

In the embodiment shown in FIG. 1, the light emitting element 27 and the light receiving element 2
A reflective optical sensor 10 is used instead of 8, and a steel ball 9 and a solenoid 12 are used instead of the steel ball 26 and solenoid 30, but the circuit shown in FIG. 7 can be applied in this case as well.

Further, in the above embodiment, the upper end side of the detection member 6 is supported using the outer ring 2 and the inner ring 4 so as to be rotatable in all directions, but the supporting means is not limited to this. Furthermore, the steel balls 9 and 26 do not necessarily have to be steel balls, and generally only need to be spherical. Further, although optical means such as the light emitting element 27 and the light receiving element 28 are used as the deviation detecting means in the above embodiment, it goes without saying that other deviation detecting means such as a proximity switch may also be used.

Further, the detection member 6 is always fixed by the spring 16 when the solenoid 12 is not activated, but on the contrary, the detection member 6 is normally rotatable, and the solenoid 12 is activated during use. The detection member 6 may be fixed.

[Effects of the Invention] As explained above, the present invention includes a detection member whose upper end side is rotatably supported in all directions, and a rolling plate attached to the detection member and on which a sphere is rotatably mounted. , a fixing means for switching the detection member to either rotatable or fixed, and a deviation detection means that is activated by movement of the sphere when the vertical axis of the detection member deviates from the vertical direction by a predetermined value or more. Therefore, even though the configuration is extremely simple, it is possible to accurately detect the target object regardless of whether it is tilted forward, backward, left or right. Therefore, if you install it in your car, it will not only prevent the car itself from being stolen, but also
It also has the advantage of being extremely effective in preventing tire theft.
