In order to achieve the above-mentioned object, the present invention provides a handlebar lock mechanism for fixing and releasing the fixing of a vehicle handlebar by engaging with a shaft portion of the handlebar. A lock member that is movable between a fixed position that makes the handle non-rotatable and a lock release position that makes the handle rotatable, and the lock member that is rotated in one direction to move the lock member from the fixed release position to the fixed position. A movable rotation member, a first position where the rotation member is a fixed position that prevents rotation of the handle, and a second position that enables rotation of the handle and disables engine operation. It is characterized in that it is provided with a drive means which is rotatable stepwise in a position and a third position which enables the rotation of the handle and enables the operation of the engine.

Further, the drive means includes an elastic member for applying a rotational force to the rotating member in the other direction opposite to the one direction, and a locking member for holding the rotating member at a predetermined angular position. An electric actuator driven in conjunction with the starter switch to disengage the locking member from the rotating member and sequentially rotate the rotating member from the first position to the third position. Is preferred.

Further, it is preferable that an operation portion which can be manually operated is connected to the rotating member via a cable for rotating the rotating member in the one direction.

Furthermore, it is preferable that an ON position detecting sensor for detecting whether or not the rotating member is arranged at the third position is provided.

Further, a vehicle speed detecting sensor for detecting a traveling state of the vehicle and the vehicle speed detecting sensor determine that the vehicle is traveling, and the ON position detecting sensor causes the rotating member to move from the third position. Holding means for holding the rotating member in the second position when it is determined that the rotating member has been separated;
Is preferably provided.

[0010]

In the vehicle handle lock mechanism according to the present invention,
When the rotating member is rotated from the first position to the second position under the action of the driving means, the lock member is disengaged from the shaft portion of the handle and moved to the fixed release position. As a result, the engine cannot be operated and the handle is rotatable. Then, when the rotating member is rotated to the third position via the driving means, the handle can be rotated and the engine can be operated. Therefore, when the engine is started, the handle must be rotated. Is unlocked, and a reliable running state is obtained.

Further, if the driving means is provided with an electric actuator which is driven in conjunction with the starter switch, the locking member is disengaged from the rotating member when the starter switch is pushed, and the rotating member is moved. Is rotated from the first position to the second position via the elastic member, and the starter switch is pushed again to rotate the rotating member to the third position and start the engine. Therefore,
The rotating member is automatically and surely arranged at a desired position in association with the operation of the starter switch, so that the handle release operation is simplified.

Further, if the operating member is connected to the rotating member via a cable, the driver can easily and securely operate the rotating member from the third position to the first position by manually operating the operating member. It can be rotated.

Furthermore, after it is confirmed via the ON position detection sensor that the rotating member is located at the third position, the ignition circuit is turned ON and the engine is started, thereby preventing erroneous operation. It will be possible
The handle is fixed and released with high precision.

When the vehicle speed detection sensor determines that the vehicle is traveling and the ON position detection sensor determines that the rotating member has separated from the third position, the rotation is performed via the holding means. The member is held in the second position. Therefore, it is possible to reliably prevent the rotating member from continuously rotating from the third position to the first position during traveling and locking the handle.

A fairing 220 is provided so as to cover the controller 96 and the front part of the vehicle (see FIG. 1).

Next, the operation of the handlebar lock mechanism 26 thus constructed will be described in relation to the motorcycle 10.

First, when the motorcycle 10 is in a stopped state, as shown in FIG. 8A, the locking projections 88 of the locking member 36 are engaged with the first locking steps 68 of the rotating member 34. The eccentric pin 66 presses the support body 54 against the elastic force of the spring member 60 toward the stem pipe 28 side, and the lock member 32 fixed to the support body 54 engages with the engagement hole of the stem pipe 28. It is inserted in the portion 28a (see FIG. 5A). Therefore, the handle is held so as not to rotate.

At this time, the operating lever 128 is arranged at the lock position (see the chain double-dashed line in FIG. 1) and the opening 12 of the controller body 98 constituting the controller 96.
0 is open. Therefore, when the key 122 is inserted into the controller main body 98 from the opening 120, the personal identification code or the like stored in advance in the non-contact type IC card 124 provided in the key 122 is read through the reading sensor 126, The CPU 200 determines whether the key 122 is appropriate.

When it is determined that the proper key 122 has been inserted, the solenoid 38 constituting the handle lock mechanism 26 is in a state in which power can be supplied via the CPU 200.
Then, when the starter switch 110 is pushed, the solenoid 38 is driven for a predetermined time, and the locking large diameter portion 93
Moves inward (in the direction of arrow E in FIG. 3). For this reason,
The locking member 36 swings in the direction opposite to the direction of the arrow D against the spring 86, and the locking projection 88 separates from the first locking step 68 of the rotating member 34, whereby the above-described rotation is achieved. The moving member 34 rotates in the direction of arrow B under the pulling action of the spring member 35 (FIG. 8).
(See B).

When the rotating member 34 rotates in the direction of the arrow B by a predetermined angle, the cam portion 72 provided on the rotating member 34 engages with the projection 90 of the engaging member 36, and the engaging member 36. 36 swings in the direction of arrow D. Therefore, the locking projection piece 88 of the locking member 36 engages with the second locking step 70 of the rotating member 34 to hold the rotating member 34 (see FIG. 8C). In this way, when the rotating member 34 rotates from the first position (lock position) to the second position (OFF position), the support body 54 and the lock member 32 cause the eccentric pin 66 of the rotating member 34 to rotate.
And the guide groove 62 of the support member 54, the guide member 62 moves integrally in a direction away from the stem pipe 28, and the fixing action of the stem pipe 28 by the lock member 32 is released (FIGS. 3 and 5B). ), The handle can be rotated. At that time, the operating lever 128 connected to the rotating member 34 via the cable 82 is connected to the operating member 128.
With rotation of FIG. 4, it automatically swings in the direction of arrow F in FIG. 1 by a predetermined angle and stops at the OFF position.

Then, when the starter switch 110 is pushed again, the solenoid 38 is driven for a predetermined time, the locking member 36 swings in the direction opposite to the arrow D direction, and the locking projection 88 rotates. The moving member 34 is separated from the second locking step 70 (see FIG. 8D). As a result, the rotating member 34 further rotates in the direction of arrow B, and the ON position detection switch 80
Are engaged with the second arcuate surface 78 of the rotating member 34 and driven (see FIG. 5C). At that time, the operation lever 128 is automatically swung via the cable 82, and is arranged at a position to close the opening 120 of the casing 118 as shown in FIG.

The ON signal of the ON position detection switch 80 is
It is sent to the CPU 200, the ignition circuit is turned on, the starter starts and the engine starts,
A state in which the vehicle can run is obtained.

When a desired point is reached and the engine is deenergized while the vehicle is stopped, the operating lever 128 is manually swung in the direction opposite to the arrow F direction in FIG. Therefore, the rotating member 34 is pulled through the cable 82, the rotating member 34 rotates in the direction of arrow A against the spring member 35 (see FIG. 9A), and the second locking step 70 is formed. The locking projection 88 is engaged to reach the OFF position (see FIG. 9B). Here, the ON position detection switch 80 has the inclined surface 76.
Is engaged with the first arcuate surface 74 to be in the OFF state, and this OFF signal is sent to the CPU 200 to turn off the ignition circuit and stop the engine.

At the OFF position, the fixation of the stem pipe 28 is released. Therefore, when fixing the handle, turn the handle in a predetermined direction,
The operation lever 128 is further swung in the direction opposite to the arrow F direction, and is arranged at the position (lock position) indicated by the chain double-dashed line in FIG. Therefore, the rotating member 34 is connected via the cable 82.
Rotates in the direction of arrow A in FIG. 9C, and the first locking step 68
The locking projection 88 is engaged with and the stem pipe 28 is non-rotatably fixed by the lock member 32 (see FIG. 9D).

As described above, in this embodiment, the handle lock mechanism 2 is interlocked with the pushing operation of the starter switch 110.
6 drives the driving means 33, and the rotating member 34.
A first position as a fixed position for preventing rotation of the handle, a second position for enabling rotation of the handle and disabling operation of the engine, and a position for enabling rotation of the handle and the engine. Is gradually rotated to a third position which enables the operation of the. For this reason, the work of fixing and releasing the fixing of the handle can be accurately and easily performed corresponding to the stopped and started state of the engine, and it is surely prevented that the handle is fixed when the engine is started. be able to.

At this time, by engaging the ON position detection switch 80 with the rotating member 34, an ON signal is sent from the ON position detection switch 80 to the CPU 200, and the ignition circuit is thereby turned ON. It is possible to more reliably and automatically prevent the handle from being fixed at the time of starting.

By the way, while operating, the operating lever 1
28 may swing from the third position (ON position) to the first position (lock position) side. In this case, CPU2
00, a signal indicating that the vehicle is traveling is sent via the vehicle speed detection sensor 204. In this state, the operation lever 1
28 is swung in the direction of arrow F to turn on the ON position detection switch 8
When 0 is turned off, that is, when it is determined that the rotating member 34 is separated from the third position (ON position), the solenoid 38 is driven for a predetermined time. Therefore, FIG.
As shown in FIG. 6, the locking member 36 swings in the direction opposite to the arrow D direction, and the cam portion 72 and the protrusion 9 that constitute the holding means 89 are formed.
0 engages with each other to prevent the rotation member 34 from rotating in the direction of arrow A. Then, the locking member 36 swings in the direction of arrow D via the spring 86, the locking projection 88 thereof engages with the second locking step 70, and the rotating member 34 is held in the OFF position. (See FIG. 10B).

As described above, in this embodiment, even if the operation lever 128 is operated during traveling, the operation lever 128 does not continuously swing from the ON position to the lock position, and is always in the OFF position. Be stopped. Therefore, it is possible to reliably prevent the rotating member 34 from rotating to the first position (lock position) during traveling.

[0044]

As described above, according to the present invention, when the rotating member is rotated from the first position to the second position under the action of the driving means, the lock member is disengaged from the shaft portion of the handle. To the unlocked position, the engine is not operable and the handle is rotatable. Then, when the rotating member is rotated to the third position via the driving means, the handle can be rotated and the engine can be operated. Therefore, when the engine is started, the handle must be rotated. Is unlocked, and a reliable running state is obtained.

If the drive means is provided with an electric actuator which is driven in conjunction with the starter switch, the starter switch is sequentially pushed to cause the rotating member to move to the first position.
The engine is started by sequentially rotating from the position to the third position. Therefore, the rotating member is automatically and surely arranged at a desired position in association with the operation of the starter switch, and the work for releasing the fixing of the handle is simplified.

Further, when the operating member is connected to the rotating member via the cable, the driver can easily and securely move the rotating member from the third position to the first position by manually operating the operating member. It can be rotated.

Furthermore, after it is confirmed via the ON position detection sensor that the rotating member is located at the third position, the ignition circuit is turned ON and the engine is started, thereby preventing erroneous operation. It will be possible
The handle is fixed and released with high precision.

When it is determined by the vehicle speed detection sensor that the vehicle is traveling, and when the ON position detection sensor determines that the rotating member is separated from the third position, the rotation is performed via the holding means. The member is held in the second position. Therefore, it is possible to reliably prevent the rotating member from continuously rotating from the third position to the first position during traveling and locking the handle.
