Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an anti-theft device for two- and three-wheeled vehicles that is capable of simultaneously locking the steering handle and the main stand in the parked position.

2. Since tricycles may be stolen when parked, conventionally known tricycles are equipped with a locking device that locks the steering handle to the vehicle body frame to prevent theft. However, even with this method, there are cases where a two- or three-wheeled vehicle is driven with the steering wheel locked and stolen.

Therefore, the present invention makes it possible to lock the main stand in the parked position at the same time as locking the steering wheel when parking the motorcycle. 2. Theft prevention of the tricycle can be more reliably achieved. 2. Its main purpose is to provide an anti-theft device.

In order to achieve this purpose, the present invention
A two- or three-wheeled vehicle in which a main stand is connected to the body frame so as to be rotatable between a standing position in which the main stand can hold the body frame in an upright position and a stowed position in which it cannot hold the body frame in the same position. a locking device provided at a suitable position on the frame; a first locking member fixed to a steering handle rotatably supported by the body frame and locked by the locking device when the steering wheel is in a parking position; a second locking member disposed on one side of the locking device and capable of assuming a locking position in which the locking device can be locked and an unlocking position in which the locking device cannot be locked;
the second locking member moves to the locking position in response to movement of the main stand to the parked position, and moves to the unlocking position in response to movement of the stand to the storage position; The present invention is characterized by comprising an interlocking connection mechanism that mechanically interlocks and connects the main stand and the second lock member.

Embodiments of the present invention will be described below with reference to the drawings.

A steering handle 2 for steering a front wheel W as usual is rotatably supported on a head pipe 1 at the front end of a body frame F of a scooter type motorcycle. A first locking member 3 is fixed to the center of the steering handle 2, and a first locking hole 4 is formed in the first locking member 3. On the other hand, a cylinder lock 5 corresponding to the first lock member 3 is fixed to one side of the head pipe 1. This cylinder lock 5 has a conventionally known structure, in which a rotor 8 with a key hole 7 opened in a housing 6 is rotatably provided, and a lock piece 9 that can be moved in and out as the rotor 8 rotates is provided. As shown in FIG. 3, the key is inserted into the keyhole 7 and the rotor 8 is
If the rotor is turned to the "LOCK" position, the lock piece 9 will protrude, and if the rotor 8 is turned to the "ON" position,
The main switch is turned OFF when the main switch of the engine is turned ON and the rotor 8 is further turned OFF. When the steering handle 2 is turned to the parking position, the first lock hole 4 of the first lock member 3 aligns with the lock piece 9 of the cylinder lock 5, and the cylinder lock 5 is "LOCKed" as described above. When the steering handle 2 is moved to the locked position, the locking piece 9 fits into the first locking hole 4 as shown in FIG. 3, and the steering handle 2 can be placed in the locked state.

Further, as shown in FIG. 3, a bracket 10 is fixed to one side of the head pipe in the vicinity of the cylinder lock 5, and one end of an outer tube 11o of a Bowden wire 11 is fixedly supported on the bracket 10. The inner wire 11i of the Bowden wire 11 protrudes from one end of the outer tube 11o, and a second locking member 12 is fixed to one end thereof, and the second locking member 12 has a second locking hole 13 into which the locking piece 9 can be inserted. is drilled. The bracket 10 and the second lock member 1
A return spring 14 is compressed between the second lock member 12 and the second lock member 12, and the resilient force of the spring 14 urges the second lock member 12 to be positioned on the lock piece 9 by pulling out one end of the inner wire 11i.

The Bowden wire 11 extends rearward along the body frame F, and its outer tube 1
The other end of the inner wire 1o is fixedly supported by a stand bracket 15 that is integrated with the body frame F, and the other end of the inner wire 11i is tied to the base of a main stand 17 that is pivotally supported 16 by the stand bracket 15. . The main stand 17 uses a toggle spring 18 stretched between the main stand 17 and the stand bracket 15 to maintain the body frame F in an upright position (see the solid line in Figure 2) and a retracted position (see the solid line in Figure 2). (see dashed lines in Figure 2). The Bowden wire 11 and the return spring 14 cooperate with each other to constitute the interlocking connection mechanism L of the present invention.

When the main stand 17 is moved to the above-mentioned stopping position, the inner wire 11i of the Bowden wire 11 moves forward inside the outer tube 11o and locks the second lock member 12, which can be locked by the cylinder lock 5 as a locking device. On the other hand, when the main stand 17 is moved to the storage position, the inner wire 11i of the Bowden wire 11 moves backward inside the outer tube 11o, and the second lock member 12 cannot be locked by the cylinder lock 5. It can be pulled into the unlocked position.

In addition, in Figures 1 and 3, 19 is the handle cover, 20
21 is a leg shield, and 21 is a cover for the head pipe and cylinder lock 5, all of which are made of synthetic resin.

Next, to explain the operation of the embodiment of the present invention shown in FIGS. 1 to 3, when the motorcycle is stopped,
When the main stand 17 is rotated to the standing position, the inner wire 11i moves forward inside the outer tube 11o, and the second locking member 12 at the tip thereof is also pushed forward, so that the second locking hole 13 is locked into the locking cylinder lock 5. It comes directly above piece 9. Next, when the steering wheel 2 is turned to the parking position, the first lock hole 4 of the first lock member 3, which is integral with the steering wheel 2, is located directly above the lock piece 9 of the second lock member 12, as shown in FIG. It is referenced as a second lock hole 13. If the cylinder lock 5 is operated to the "LOCK" position as described above, the lock piece 9 will protrude and
It passes through the lock holes 4 and 13, and at the same time as the steering handle 2 is locked, the main stand 17 is locked in the standing position.

In this embodiment, the cylinder lock 5 can also be used to turn on and off the main switch of the engine.

FIG. 4 shows a modified example of the cylinder lock 5.
In this modification, the lock piece 9' is supported by a compression spring 23 in a guide support part 22 that is provided in the housing 6 so as to be retractable. The locking piece 9' is configured to sink into the guide support 22. Therefore, if the cylinder lock 5 shown in FIG. 4 is used, even after the steering handle 2 is locked and the main stand 17 is stopped, the second lock hole 13 of the second lock member 12 can be locked by the lock piece 9. This allows the main stand 17 to be locked.

In the present invention, other locking devices may be used instead of the cylinder lock 5.

As described above, according to the present invention, the locking device is provided at a suitable position on the body frame; and the locking device is fixed to a steering handle that is rotatably supported on the body frame, so that when the steering wheel is in the parking position, the locking device a first locking member that is locked by; a second locking member that is disposed on one side of the locking device and can take a locked position in which it can be locked by the locking device and an unlocked position in which it cannot be locked; 2
The main stand and the main stand are arranged such that the locking member moves to the locking position in response to movement of the main stand to the parking position and moves to the unlocking position in response to movement of the stand to the storage position. Since it is equipped with an interlocking connection mechanism that mechanically interlocks the two locking members, it is possible to lock the steering wheel in the parking position and lock the main stand in the parked position at the same time, thereby preventing theft. This is effective in terms of countermeasures, 2. There is no risk of the main stand being inadvertently released to the parked position when the tricycle is parked, and 2. The tricycle can be stably supported even when an external force is applied to the tricycle.

In particular, the second locking member for locking the main stand needs only to be mechanically connected to the stand so as to simply respond to the main stand as described above.
The structure of the interlocking connection mechanism between the lock members can be simplified as much as possible, contributing to cost reduction.
