DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a handle lock mechanism for a motorcycle, for example.

[0002]

2. Description of the Related Art Conventionally, as a handle lock mechanism for a motorcycle, for example, after operating a main switch to stop an engine, a handle is locked in conjunction with the switch, or after the engine is turned off, a separate body is provided. A method of locking a handle with a lock key and the like are generally used, and a device in which a handle lock mechanism is linked when a stand is set up is also known. For example, in Japanese Utility Model Application Laid-Open No. 58-75092, a wire is connected between a stand and a handle lock slide bar. In this state, the handle lock slide bar is detached from the hole of the lock plate with the stand raised through the operation of the stand lock lever.

[0003]

However, in the former method in which the engine is stopped by the main switch and then the handle is locked in conjunction with the switch, the locking operation is cumbersome, and the system is separate from the main switch. The method of locking the steering wheel with a lock key or the like has a problem that it is difficult to operate in a dark place or a narrow place, and the lock operation is similarly troublesome. Further, in the latter technique such as Japanese Utility Model Application Laid-Open No. 58-75092, it is necessary to operate the unlocking operation means separate from the stand, so that the unlocking operation is somewhat complicated and the structure is complicated. Problem.

Accordingly, an object of the present invention is to provide a handle lock device which eliminates the hassle of the handle lock operation and which automatically releases the handle lock when the stand is raised.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention relates to a handle lock device which locks a handle in conjunction with operation of a stand of a motorcycle.
A lock pin slidable between a handle lock position and an unlock position and urged to the unlock side by a first urging member, and interlocked with an operation of abutting the base end side of the lock pin and erecting a stand Then, a pressing lever for urging the lock pin toward the handle lock side by the second urging member is provided, and when the stand is set up, the urging force of the second urging member is reduced by the urging force of the first urging member. , The lock pin is urged toward the handle lock side, and when the stand is raised, the urging force of the first urging member overcomes the urging force of the second urging member to slide the lock pin toward the unlock side. I tried to make it.

As described above, the steering wheel is locked in conjunction with the operation of the stand, so that when the vehicle is parked after traveling, the steering wheel is automatically locked only by raising the stand. Will disappear. Further, when the stand is raised, the lock pin is always slid toward the unlock side by the first biasing member, and only when the stand is standing, the biasing force of the second biasing member is applied to the first biasing member. By overcoming the forces, the steering wheel lock is automatically released with the stand raised.

Here, the motorcycle includes not only a scooter with a stand and a motorcycle with a motor, but also a bicycle.

Further, in the present invention, the lock pin slides to the handle lock position when the handle is adjusted to a predetermined phase.

For example, if the handle is locked with the handle turned to one side, the anti-theft effect can be further enhanced. In operation, after the stand is set up, the handle is turned to one side. You just need to do it.

According to a third aspect of the present invention, the stand is provided with a stand lock mechanism for locking the position of the stand when the stand is upright.

If the position of the stand is locked by the stand lock mechanism, the stand can be locked and the handle can be locked by a single operation.

[0012]

Embodiments of the present invention will be described with reference to the accompanying drawings. Here, FIG. 1 is an explanatory view showing a schematic configuration of a handle lock device according to the present invention, FIG. 2 is a horizontal sectional view of a main part of the handle lock mechanism, FIG. 3 is a plan view of a stand lock mechanism, and FIG. FIG.

[0013] The handle lock device according to the present invention is configured as a handle lock device linked to a motorcycle stand such as a scooter, and can automatically lock the handle only by standing up for parking or the like. In addition, simply unlocking the stand automatically unlocks it.

That is, as shown in FIG. 1, the handle lock device 1 includes a handle lock mechanism 3 attached around a head pipe 2 and a stand lock mechanism 5 provided around a stand 4. A cable 6 is connected between the handle lock mechanism 3 and the handle lock mechanism 3.

A stem pipe 7 connected to a handle (not shown) is rotatably provided inside the head pipe 2. The handle lock mechanism 3 rotates the stem pipe 2 with respect to the head pipe 2. The handle is locked by restricting movement.

The handle lock mechanism 3 includes a swing lever 10 connected to the cable 6 and swingable around a swing shaft 8, and a spring 11 as a second urging member for the swing lever 10. And a lock pin 13 which is engaged with the press lever 12 and can swing around the swing shaft 8, and a lock pin 13 which comes into contact with the push lever 12.
Is urged toward the pressing lever 12 by a spring 14 as a first urging member.

An insertion hole 2h through which the lock pin 13 can be inserted is formed in the head pipe 2 in the direction of the tip end side of the lock pin 13, and as shown in FIG. A locking hole 7h into which the lock pin 13 can be fitted is also formed at one location in the circumferential direction. When the handle is in the straight traveling state, the locking hole 7h is displaced from the position of the insertion hole 2h of the head pipe 2, and the handle is moved to one side (left side in the embodiment).
When the vehicle is turned, the position is matched with the position of the insertion hole 2h of the head pipe 2.

When the stand 4 is in the upright state, the swing lever 10 is pulled by the cable 6 and swings counterclockwise in the drawing, and the spring 11 is contracted by this swing. In addition, a spring force for swinging the pressing lever 12 counterclockwise is applied, and the urging force of the spring 12 with respect to the pressing lever 12 overcomes the urging force of the spring 14.

When the stand 4 jumps up, the cable 6 is slackened and the swinging lever 10 swings clockwise to recover, and the pressing force of the spring 11 transmitted to the lock pin 13 via the pressing lever 10 is reduced. The force is set to be equal to or less than the urging force of the spring 14.

The stand lock mechanism 5 has a lock means 15 attached to the vehicle body side and a lever 16 which is fixed to the stand 4 integrally.
When the lock hole 16h is formed and the stand 4 is in the upright state, as shown in FIG. 3, the lever 16 enters into the recess of the lock means 15, and when the push button 17 of the lock means 15 is pushed, the push button 17 The distal end shaft of the button 17 is inserted into the lock hole 16h so as to be in a locked state.

The lock means 15 is provided with an insertion portion 18 into which a key or the like can be inserted.
By operating a key or the like inserted from the insertion portion 18, the push button 17 is pulled out and can be unlocked.

The operation of the above-described handle lock device 1 will be described with reference to FIG. In a state where the stand 4 is flipped up, as shown in FIG. 4A, the cable 6 is loosened, and the force of the spring 11 transmitted to the lock pin 13 via the pressing lever 12 is weaker than the urging force of the spring 14. The lock pin 13 is pushed back by the spring 14, and the tip of the lock pin 13 is located at a position away from the stem pipe 7.

Next, when the stand 4 is raised when the vehicle is stopped, the cable 6 is pulled, and the swing lever 10 swings as shown in FIG. The force of the spring 11 transmitted to the spring 13 overcomes the urging force of the spring 14. For this reason, when the lock pin 13 moves forward and the tip comes into contact with the stem pipe 7, the lock pin 13 cannot further move forward and enters a lock standby state.

When the position of the locking hole 7h of the stem pipe 7 is adjusted to the position of the insertion hole 2h of the head pipe 2 by rotating the stem pipe 7 by operating the handle, FIG. As shown, the lock pin 13 advances and fits into the locking hole 7h, and the stem pipe 7 is restricted from rotating.

In this state, if the stand 4 is locked by pushing the push button 17 of the stand lock mechanism 5 shown in FIG. 1, both the stand 4 and the handle are locked, and this operation is extremely simple.

When traveling, the key is inserted from the insertion portion 18 of the stand lock mechanism 5 and operated, and the push button 17 is retracted to unlock the stand 4. The handle is unlocked, and these operations are also easy.

The present invention is not limited to the above embodiment. Those having substantially the same configuration as those described in the claims of the present invention and exhibiting the same operation and effect belong to the technical scope of the present invention. For example, the lock position by the lock pin 13 may be a position other than the stem pipe 7, and the type of the motorcycle is arbitrary.

[0028]

As described above, the handle lock device according to the present invention locks the handle by sliding the lock pin in conjunction with the operation of the stand of the motorcycle and locks the handle by the first biasing member. Because the pin is always urged to the unlock side, when parking after driving, the handle is automatically locked just by raising the stand, eliminating the hassle of locking the handle, and at the same time, when the stand is raised The handle lock is automatically released. Further, if the lock pin is slid to the handle lock position when the handle is adjusted to the predetermined phase, the anti-theft effect can be further enhanced. If a stand lock mechanism is provided to lock the position of the stand with the stand upright, the handle is locked simultaneously with the stand lock, which is convenient.
