Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a gear change operation notification device for bicycles that is used for bicycles having a speed change mechanism, and more particularly, to an alarm system for informing bicycles of bicycles having a speed change mechanism. Regarding the device that can be easily known by the operation of the device, this bicycle KP, in particular, can be attached to the axle of the rear wheel by operating the gear shift lever # attached to the body vibrator, etc.)
The number of gears is changed by remotely operating the gear shift mechanism and hooking a chain between several gears. Switch to another regular gear position! If the M operation is not performed reliably, there is a risk that the chain will come off the transmission gear and the transmission mechanism will malfunction.

The present invention provides a warning sound for informing the shift operation of the shift lever when the shift lever is not shifted to the normal gear position (i.e., when the shift lever is in the 5th gear and the 4th gear position).
When the driver stops at a position intermediate between one regular gear position (such as the position midway between Pi and the other regular gear position), the driver can shift the VC gear shift lever by continuing to move it. This system notifies the driver that the gear has not been shifted to the normal gear position and urges the driver to accurately shift the gear to the normal gear position, thereby ensuring reliable gear shifting.

Hereinafter, we will discuss an embodiment of the bicycle gear shift operation notification device Jili of the present invention shown in the drawings! Q will be clear.

(7) is a gear shift operation member that is attached to the body pipe (1) of the bicycle body (1); (8) is a wire cable that connects this gear shift operation member (73) and the gear shift lIA mechanism (2);
The speed change operation of the speed change operation member (71) and the speed change operation of the par (9) are transmitted to the guide gear 16) of the speed change substructure 12) via this wire cable (8)k, and then the chain (5)

In this gear change operation notification device of the present invention, the operating member (7) K is attached to the operating member (7) K.

A) It has nine delay contacts (18B) (18G) (181), ), and operates the transmission t!4 (21) via the pull wire cable (81) by the shift operation of the gear shift lever i9J The WC possible vJ contact 0I switches the corresponding fixed contact by passing through the comb-teeth contact piece of the delay contact. (For example, the shift lever (9) is switched from the 5th When the gear is shifted to positive m, the movable dependent point 0◆ extends from the sixth fixed contact (14C) to the fifth ail contact piece (18G) of the delay contact aη, and then changes to the fourth contact (16DJl).
The VC is designed so that it comes into contact with the VC. ) The notification unit (121 is the first switch unit aO of V411)

Said j! The delay action section α is a circuit consisting of a charging/discharging I capacitor (2) connected to the delay contact αη, a discharging resistor (total), a control T transistor (2), and a tortoise. By contacting the delay contact aη of the capacitor f (2a is charged, and the delay contact αη of the contact 04 is separated), the capacitor f is discharged through the resistor Ot. LThe control t transistor c! during charging and demagnetizing time only! 41tl- is turned on, power is supplied to the Wt Ikeda power supply Vt1lI recording and notification ff1413, and the notification section t1 is activated for only a certain period of time.

Then, when the speed change lever (97F:R speed) is operated, the speed change lever (9J) moves out of one positive M gear position, and the warning *mQDK power is supplied to start the sounding of the warning sound. Then, when the shift lever (9) reaches another regular gear position, the movable contact (t41) switches from the delay contact αη to the fixed contact corresponding to the number of gears, so the battery (
c) - The source is a movable contact (from 4 to a fixed contact that corresponds to the number of gears), and power is supplied to the corresponding indicator light bulb.
i# By delaying the discharge time of the capacitor fQ2j and turning off the control transistor (2) of the delayed operation vJto a3, the power supply to the display bulb and the alarm horn 12υ is stopped.) Therefore, The lever warning signal υ continues to operate when the gear shift lever (9) is out of the normal gear position, and continues to notify the driver that the gear shift lever (9) is not in the correct gear position. % rough shift lever (9)
When the shift lever (9) is shifted to the normal gear position, the shift gear number is displayed by illumination of the indicator light bulb, and the sound of warning 96 (jl) is made only for a certain period of time after the shift lever (9) is shifted. There is.

Fig. 5 shows an embodiment in which a 7-segment type light emitting diode (2) is used as an electrical indicator in the notification section of the present invention, and an electronic buzzer (2) is used as an alarm. Another embodiment of the present invention is shown in which the operating time of the alarm, which is the alarm, and the length of the display time of the 7-segment light emitting diode, which is the weather indicator, are shown. However, in these figures, %Gou is a multipipulator %(2) is a sounding body, (To) is a diode matrix, Gυ is a sounding time m control circuit, and this Oboromoe circuit (B) is a capacitor (To). has a resistance (to),
Further, the discharge time of the capacitor (to) is shorter than the discharge time of the charge/discharge capacitor f-.

The bicycle #J gear shift operation notification device of the present invention is as described above, and is particularly attached to the bicycle body, and serves as a shift lever that operates the gear shift mechanism of the bicycle, and a warning horn that notifies the gear shift lever ID gear shift operation 1kIIL. Equipped.

The alarm starts operating when the shift lever moves out of one normal gear position, and is configured so that it does not stop operating until it reaches another normal gear position. Therefore, when the gear shift lever is shifted to the normal shift position, this can be confirmed by once operating the alarm and then stopping the operation. Gear Position VC When the gear shift is not being operated, the alarm continues to operate, alerting the driver that the shift lever is not being shifted to the normal gear position, and ensuring that the driver correctly shifts to the normal gear. This will encourage you to turn the gear shift line to the gear position, thereby ensuring a reliable gear shifting operation, completely preventing the chain from coming off the gear, and providing you with a very useful safety feature. can. Roughly speaking, according to the present invention, each time a bicycle rider performs a reliable gear shifting operation, only the time required for the end of that operation is notified, and only the time required for that operation is notified, and only one time, such as °1a, is deducted for this time. This means that the power source is not consumed at all times, and therefore it is possible to reduce the LD power consumption.
