BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a direction indicator device for a motorcycle, and more particularly to a direction indicator device for a motorcycle which can automatically turn off a blinking direction indicator lamp by an operation after traveling a curve. is there.

[0002]

2. Description of the Related Art Turning a motorcycle (hereinafter referred to as a motorcycle) to the right,
The turn signal device for turning left is usually performed by blinking blinker lamps provided on the left and right of the front and rear wheels of the motorcycle. The operation of the turn signal lamp is performed by a switch provided on the handle portion, which indicates the direction of right turn or left turn according to the Road Traffic Law, and the turn signal light is turned off by the switch operation after turning right or left. However, as described above, the operation of indicating the traveling direction, especially the turn-off of the turn signal lamp, depends on the switch operation.Therefore, it is often seen that the lamp is forgotten after turning right or left, which is one of the causes of the accident. It is also accompanied. In order to improve such a problem, as shown in Japanese Patent Laid-Open No. 60-22542, after the operation of the direction indication, it is detected that the motorcycle has traveled a certain distance, and the operation of the direction indicator is detected. There has been proposed a direction indicating device adapted to be restored.

[0003]

However, the direction indicating device described in Japanese Unexamined Patent Publication No. Sho 60-22542 described above can be applied to various automobiles such as automobiles as well as motorcycles, and the blinker lamp is forgotten to be turned off. Although it is useful for eliminating troubles due to the above, not only is the direction indicator device complicated and the equipment cost high, but the restoration operation of the direction indicator depends on the mileage of the motorcycle after the direction instruction.
The operation of the turn signal must be performed by predicting the distance to the intersection. For example, when a car is congested and the direction indicator is operated considerably backward from a position about 30 m from the intersection according to traffic regulations, When the turn signal lamp goes out by the time the intersection is reached, and conversely the operation of the turn signal is delayed and the direction is indicated near the intersection,
The inconvenience occurs that the lamp does not go out for a while after turning right or turning left. The present invention solves the above-mentioned inconvenience, and provides a direction indicator device for a single vehicle that can erase the indication of the direction indicator at the time when the curve running to turn left or right at the intersection is completed.

[0004]

SUMMARY OF THE INVENTION The present invention utilizes the large inertial action of mercury, which has a high specific gravity and conductivity, and a change in the running posture of the single vehicle when the vehicle changes from a curve running to a straight running. The above problem was solved. That is, the turn signal indicating device for a motorcycle according to the present invention is located between two electromagnets provided at a distance, and is moved to either one of the electromagnets by an operation to contact with the electromagnet. In the above, a direction indicating switch equipped with a spring that elastically separates the sliding part between the electromagnets from the electromagnet, and a closed chamber in which the central part of the inner surface is bent upward in a bow shape, and mercury is provided in the sealed chamber to form an air part. The control unit is filled with the remaining fluid so that the control unit is horizontally filled with two conductive terminals whose lower end is immersed in the mercury in a horizontal state at the end of the closed chamber. The lead wire extending from the power supply section is connected to one of the terminals, the lead wire extending from the electromagnet of the operation switch is connected to the other terminal, and the lead wire extending from the slide section of the operation switch is connected. Formed by connecting to the turn signal lamp through a flasher to the line. The shape of the closed chamber in the above controller is
When the sealed chamber is tilted and then returned to the horizontal position, the mercury inside flows left and right, and at least one of the air parts
A curved shape in which the parts move to the opposite side is particularly desirable.
Then, terminals for left turn control and right turn control may be provided at both ends of the moving air portion.

[0005]

[Function] When the slide portion of the operation switch is moved toward one electromagnet for turning left or right, the slide portion is attracted and held by the electromagnet which is energized and excited.
The blinker lamp blinks through the flasher by the output current from the slide part. Then, when the motorcycle travels in a curve for turning left or right and the posture of the motorcycle leans to the left or right, the mercury in the control unit once flows to the tilt side in the sealed chamber and the mercury water level at the end rises, When the single vehicle shifts to the straight-ahead state and the single-vehicle posture is restored to the upright state after the end of the curve running, mercury flows to the opposite side this time. And when mercury flows back to the other side,
Due to the inertial action of mercury with a high specific gravity, the water temporarily deviates largely to the opposite side, and the mercury water level at the end where the terminal exists is greatly lowered, thereby separating the mercury from the terminal and interrupting the current between the terminals. Then, by cutting off the current, the electromagnet is demagnetized, the sliding portion of the operation switch is restored to the center by the elasticity of the coil spring, the output current from the sliding portion is also cut off, and the winker lamp is automatically turned off.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to the drawings showing an embodiment of the present invention, in FIG. 1, 1 is a direction indicating switch mounted on the steering wheel side of a motorcycle, 2 is a power supply unit introduced from the ignition of the motorcycle, Reference numeral 3 is a controller for the electric current from the power source unit 2, which is attached to an appropriate position such as an intermediate position between the left and right handles. 4 is a flasher for interrupting the current intermittently by bimetal, IC, etc.
5 is a left turn signal lamp, 6 is a right turn signal lamp, and 7 is a buzzer.

The direction indicating switch 1 comprises an operating portion 11, a slide portion 12 and electromagnets 13 and 14 provided on both sides of the slide portion 12, and a coil spring 15 is provided between the slide portion 12 and the electromagnets 13 and 14. 16 is provided in an insulated state, and normally (during straight running), the slide portion 12 is kept in non-contact with the electromagnets 13 and 14 on both sides by the action of the coil springs 15 and 16. Then, when the operating portion 11 is slid in the direction of one arrow for turning left or right, the sliding portion 12 comes into contact with and is attracted to one of the electromagnets 13 or 14, and then the electromagnets 13 or 14 are demagnetized. , The restoring force of the coil springs 15 or 16 compressed by the movement of the slide portion 12 returns to the original position, and the non-contact state is established. FIG. 1 shows a non-contact state.

As shown in the figure, the controller 3 for controlling the current from the power source 1 is filled with mercury 32 leaving an air portion 33 in a horizontally long closed chamber 31 whose central portion is curved upward in an arc shape. The control chamber 3 is horizontally provided at the end of the closed chamber 31 with two conductive terminals 34 and 35, the lower end of which is immersed in the mercury 32, at a distance from each other. ing.

Further, the space shape of the closed chamber 31 is the same as the closed chamber 3
When 1 is tilted, the mercury 32 inside flows to the tilt side,
A shape in which the mercury surface at the end where the terminals 34 and 35 are present largely drops due to the flow is particularly desirable.

The conductive wire 21 extending from the power source section 2 is divided into left and right and is connected to one of the terminals 34, 34 whose lower end is immersed in the mercury 32 in the above-mentioned closed chamber 31, and further the mercury 32.
Is connected to the other terminal 35, 35 via the lead wire 22, 22 extending from the left and right electromagnets 13, 14 to the other terminal 35, 35, and both terminals 34, 35 in the sealed chamber 31 are connected. Is in contact with mercury 32
The electric current output from is supplied to the left and right electromagnets 13 and 14, and the electromagnets 13 and 14 are in their excited states. On the other hand, the lead wire 23 connected to the flasher 4, the turn signal lamps 5, 6 and the buzzer 7 is
It is connected to the slide portion 12 of the direction indicating switch 1 described above. Therefore, turn switch 1 to turn left
When the operation unit 11 of the above is slid to the left side, the slide unit 12 is attracted and held by the left electromagnet 13 as shown in FIG. 2, and the output current of the power supply unit 2 is applied to the lead wire 23.
When the turn signal lamp 5 on the left blinks and the buzzer 7 sounds, and when the direction indicating switch 1 is similarly operated to the right, as shown in FIG.
The electric current passes through, the blinker lamp 5 on the right side blinks, and the buzzer 7 sounds.

Then, the operating portion 11 of the direction indicating switch 1
After the end of the left turn, due to the inertia generated when the mercury between the 34 and 35 terminals returns to the horizontal direction, the current to the electromagnet is momentarily separated and the electromagnet is instantly cut off, and the coil spring 15 or 16 is restored to the central position automatically. Therefore, the manual restoration operation of the operation unit 11 of the direction indicating switch 1 is not necessary, the winker lamp 5 or 6 is turned off, and the buzzer 7 stops ringing.

As described above, the direction indicator for a motorcycle according to the present invention is operated by the manual operation, the turn signal lamp 5,
6 and the buzzer 7 can indicate the direction and cancel it, but even if the canceling operation is forgotten, the current is automatically cut off after the right turn or the left turn, and the direction switch 1 can be restored to the inoperative position. . That is, for example, in the case of turning left at an intersection, when the motorcycle reaches a predetermined position up to the intersection, if the slide portion 12 is moved to the left by operating the operation portion 11 of the direction switch 1 as in the conventional case, When 12 contacts the electromagnet 13, the current of the power supply section 2 causes the blinker lamp 5 for left turn to blink through the flasher 4 as described above, and at the same time, the buzzer 7 sounds to indicate that the vehicle turns left at the next intersection. .

Then, when the motorcycle enters the intersection, the vehicle body leans to the left because the vehicle travels in a curve, and at this time, the mercury 32 of the controller 3 moves to the left of the closed chamber 31 and the air portion 33 moves to the right. Then, the level of the mercury 32 at the left end of the closed chamber 31 rises, so that the left terminals 34, 3 of the closed chamber 31
5, the connection state via the mercury 32 is also stable, and the left turn signal is maintained. Then, the left turn at the intersection is over,
When the single vehicle shifts to straight running and the posture of the single vehicle is restored to the upright state, the mercury 32 in the closed chamber 31 is applied with an inertial force and flows to the right.

Therefore, since the mercury 32 has a large specific gravity, the inertia acts greatly when moving to the right with the restoration of the posture of the motorcycle, and the mercury 32 once goes too far to the position shown by the broken line in FIG. The level of mercury at the left end of the installed closed chamber 31 temporarily drops greatly, the mercury 32 separates from the terminals 34, 35, the current between the terminals 34, 35 is cut off, and the electromagnet 13 is demagnetized. Slide part 1
At the same time that 2 is restored to its original position by the restoring elasticity of the compressed coil spring 15, the winker lamp 5 is turned off, the buzzer 7 is also stopped ringing, and the direction indication is automatically canceled. After that, the mercury 32 in the closed chamber 31
Level is restored as shown in FIG. 1, and both terminals 34, 35 are restored.
However, since the direction indicating switch 1 has already been restored, no current flows in the direction indicating portion and the state is the state before the direction indicating operation.

FIG. 3 shows the state of a right turn, but the operating procedure is the same as in the case of the above left turn.
The description is omitted.

The controller 3 has a closed chamber 31 for left turn.
And a right-turning closed chamber 31 are separately provided, but one closed chamber having a shape in which the left and right closed chambers 31, 31 are integrally coupled is provided in the central portion, and mercury is filled therein. The present invention can be satisfied even if terminals for left turn and right turn are arranged on both sides of the closed chamber.

[0017]

As described above, the direction indicator for a motorcycle according to the present invention is located between the two electromagnets 13 and 14, and is moved to either one of the electromagnets 13 or 14 by an operation to move to the electromagnet 13 or 14. The direction indicator switch 1 including the contacting slide portion 12 and the coil springs 15 and 16 elastically separating the slide portions from the electromagnets 13 and 14 on both sides when not operating, and the center portion of the inner surface bent upward in an arc shape. The closed chamber 31 is provided, and mercury 3 is stored in the closed chamber 31.
2 is filled so as to be flowable with the air portion 33 remaining, and mercury 32 is provided at the end of the closed chamber 31 in a horizontal state.
The controller 3 is composed of two conductive terminals 34, 35 having their lower ends immersed therein and arranged at intervals, and the lead wire 21 extending from the power supply unit 2 to one of the terminals 34, 35. , And the directional switch 1 at the other terminal
Since the lead wires 22 extending from the electromagnets 13 and 14 are connected, and the turn signal lamps 5 and 6 are connected to the lead wires 23 extending from the slide portion 12 of the direction indicating switch 1 via the flasher 4, respectively.
As described above, in front of the intersection, the signal for left turn or right turn displayed by operating the direction indicator switch 1 indicates that when the tilting posture in which the single vehicle travels in the curve at the intersection and the vehicle finishes the curve travel, the single vehicle shifts to the straight traveling state. Mercury 32 of control unit 3
In the closed chamber 31, due to the inertial action based on the variation of the posture of the motorcycle, the current temporarily flows largely to the opposite side, the current between the terminals 34 and 35 is cut off, and the indication of the direction can be automatically erased. . Therefore, even if you forget to turn off the direction indicator signal displayed before entering the intersection after passing through the intersection, it will be turned off due to the change in the posture of the motorcycle when you restore straight driving from curving, and the erasing of this direction instruction Since it automatically ends instantly after the end of driving, troubles and accidents due to forgetting to turn off the direction can be prevented.
