6 and the lock groove 22 of the lock gear 16
And release the handle lock. Then, after confirming that the lock key 7 has been turned to the end of the open side of the cylinder lock 6 and releasing the finger from the push button 27, the safety lock rod 28 returns by the action of the safety lock spring 26, and the plug is inserted. The locking end 28b is engaged with the unlocking locking groove 25 of the corresponding cylinder lock 6 to lock the cylinder lock 6 safely with the lock key 7 inserted.

Therefore, as shown in FIG. 14, the stopper 9 of the stopper means is maintained at the position moved to the open side by the operation projection 8 as the operation means of the cylinder lock 6 of the lock means, and does not move to the handle lock side. In this state, although not shown, the lock key 7 does not come off.

Next, for locking, the push button 27 is pressed to push down the safety lock rod 28 which engages with the cylinder lock 6 of the lock means, and the insertion locking end 28b is unlocked by the cylinder lock 6. The cylinder lock 6 is turned by turning the lock key 7 counterclockwise in this embodiment, and the operation protrusion 8 serving as an operating means of the cylinder lock 6 is turned by simultaneously turning the lock key 7 counterclockwise in this embodiment.

At this time, if the tip of the stopper 9 does not coincide with the lock groove 22 of the lock gear 16, the engaging portion 9a
Is stopped at the position where the outer diameter of the engagement adjustment spring 1 is reached.
2, the linkage base 9b moves to rotate the cylinder lock 6 to a required locking position. When the user releases the push button 27 and raises the safety lock rod 28, the insertion lock The toe 28b is inserted into the locking groove 24 of the cylinder lock 6, and the tip of the stopper 9 is
The cylinder lock 6 can be safely locked and locked to the head lock body 4 in a state where the cylinder lock 6 does not fit into the lock groove 22 of the cylinder lock 6. When the handle 23 is slightly turned to the right or left, the lock gear 16 rotates, and when the tip of the stopper faces the lock groove 22, only the engagement portion 9a is pushed out by the action of the adjustment engagement spring 12 to lock the lock. The lock gear 16 is stopped by fitting into the groove 22. Thus, the handle 23 is locked to travel with respect to the frame, and the operation of the handle is disabled. Although not shown here, the lock key 7 is prevented from coming out of the cylinder lock 6 by an internal mechanism of the cylinder lock 6.

[0030]

According to the bicycle handle lock device of the present invention, the head lock body is attached to the upper part fixed to the upper end of the head pipe as described above, and the head lock body is attached to the head lock body by a spring. A stopper means which always slides in the opposite direction is provided, and a lock key is inserted from the outside, and an operation means such as an operation projection provided on the cylinder lock or the like is provided so as to be rotatable by a required angle. Since the linking portion is linked and selectively engages with the lock groove of the lock gear fitted and locked to the front fork, the stopper means is constantly urged away from the lock gear, and the locking means of the stopper means is operated. Even if an error such as a mistake or failure occurs, the stopper means does not engage with the lock gear, and safety during traveling can be ensured.

Next, the stopper means is urged by an engagement adjusting spring in the axial direction of the head pipe, and is provided on an engaging portion which is capable of compressing and adjusting the engagement adjusting spring. When the stopper means is moved in the axial direction of the head pipe of the handle lock, even when the tip of the engagement portion does not match the lock groove of the lock gear and hits the outer periphery and cannot be moved, the lock key is operated to operate the operation means. By turning the engagement adjusting spring and compressing the engaging portion of the stopper means by moving the linking portion of the stopper means, the handle can be slightly turned so that the locking groove of the lock gear matches the engaging portion of the stopper means. The engagement portion is automatically fitted by the action of the engagement adjustment spring, and the operation of the handle lock is easily completed.

Since the locking groove is provided on the outer periphery of the cylinder lock and the safety lock spring is engaged with the locking groove by the spring, the spring is pushed back by the spring when the stopper means is engaged with the lock gear. There is no safety while traveling.

At the time of locking, by pushing a push button connected to the safety lock rod, the tip of the safety lock rod comes out of the lock groove on the outer periphery of the syringe lock to release the safety lock of the cylinder lock, and the handle lock and the lock are released. It can be done at the same time.
