The main leg storage lock 11 is an anti-theft device used to prevent the main leg 12 from being folded up. If the main leg storage lock 11 is opened and the main leg 12 is put away, the motorcycle can travel. The shunt wire rope 13 branched from the joint 10 is connected to the valve type switch mechanism 4, and the valve type switch mechanism 4 can be driven to open the valve through interlocking with the unlocking of the main leg storage lock 11, and the key can be inserted into the main switch 3 to realize connected. The joint 10 is formed so that when the main outrigger storage lock 11 is intended to be opened and the steering wire rope 9 is loosened, the shunt wire rope 13 is slackened.

As shown in Figures 3-5, one end of the shutter 15 that can be freely closed and covered above the key socket 14 arranged on the upper end surface of the main switch 3 is rotatably mounted to the main switch 3 through a support shaft 16, and the other end is connected to the main switch 3. One end of branch wire rope 13.

The shunt wire rope 13 is introduced into the rear end of the pulling rod 17 integrally stretched out from the main switch 3, and the valve 15 is rotated clockwise in the figure by the compression coil spring 18 between the pulling rod 17 and the valve 15. However, except during the unlocking operation, the shunt wire rope 13 compresses the coil spring 18 so that the shutter 15 rotates counterclockwise to the direction covering the position above the key insertion hole 14 for traction.

When operating the operating knob 8 in the unlocking direction, the shunt wire rope 13 is loosened in the joint 10 as shown in FIG.

Next, the joystick and the main outrigger lock will be described based on Figs. 6-9. First as shown in Figure 6, the seat 5 is locked on the vehicle body side by the seat lock 7 supported on the rear portion of the vehicle frame 20, and the same as the main switch 3, it can be opened by a key. As will be described in detail later, the operation knob 8 as the unlocking operation part is arranged in the storage box, and one end of the manipulation guide 9 is connected to the operation knob 8, and the other end is connected to the main leg 12 provided on the handle. Main outrigger lock (as described later), and it can be unlocked.

The main leg storage lock is a device used to prevent theft during parking, and the locking of the seat lock 7 is released. Unless the joystick 8 is operated normally, the main leg 12 is in an upright state, and the motorcycle cannot travel. On the other hand, when operating the joystick 8 normally to release the main support leg storage lock, the main support leg 12 can be moved by bringing down and retracting the main support leg 12 .

The steering wire rope 9 is arranged along the inner side of the rear part of the vehicle frame, and in the joint 10 arranged on the way, the shunt wire rope 50 of the aforementioned steering lock is branched. The shunt wire rope 50 branched from the joint 10 is arranged on the inside of the vehicle body cover along the front of the vehicle frame to the steering lock. At the same time, if the joystick 8 is turned in the lockable direction, the steering wire rope 9 will be pulled together, thereby realizing the lockable lock. lock operation.

The outrigger bracket 23 is welded to the horizontal duct 22 connecting the middle parts of the left and right vehicle frames 20, and the outrigger bracket 23 forms a wall part 23a around it to form a container shape opening upward, and the upper end of the main outrigger 12 is The support shaft 53 is rotatably mounted on the rear end of the support bracket 62 to lock the upper end of the support bracket 62 through the main leg storage lock. The main leg 12 is pushed by an unshown reverse spring so as to selectively rotate to the upright position or the storage position.

Fig. 7 is a view showing the inside rear part of the storage box 6 shown from the front (direction of arrow B in Fig. 6). The joystick 58 is rotatably supported. One end of the fulcrum 24 runs through the rear wall 25 and stretches out to its rear, where the arm 27 is integrally arranged, and its front end is connected to one end of the operating wire rope 9 . The rotation of the joystick 8 is restricted by stop slopes 28 a , 28 b formed at left and right upper ends of a stop plate 28 fitted to the rear wall 25 .

The position of the arm 27 is to rotate the joystick 8 clockwise in the figure to contact the locking position shown by the solid line of the stop slope 28b, tension the control wire rope 9, and when it is in the position to rotate to the opposite side to contact the stop slope During the position shown in the phantom line of 28a, the manipulation steel wire rope 9 is slack.

By reversing the direction of rotation of the arm 27, the lever 8 can be fixed in the locked position or the open position. That is, at the locked position or the opened position, the manipulation wire rope 9 is set so as to pass through the opposite side while clamping the center of the fulcrum 24, if the manipulation lever 8 is in the locked position shown in solid line and shown in imaginary line Rotate between the open positions, then the position of the arm 27 is reversed with the center of the fulcrum 24 as the stop point, and at the reverse rotation position, positioning is performed by manipulating the elastic force of the wire rope 9 and the return spring 30 described later.

The symbol 25a in the figure is the access slot of the locking member 26 arranged on the bottom surface of the seat, and 7a is the hook of the seat lock member 7 engaging the access slot. The seat lock 7 is fitted on a cross pipe 20 a provided between upper positions constituting the rear at left and right positions of the vehicle frame 20 (refer to FIG. 6 ).

Next, the detailed structure of the main leg accommodation lock is demonstrated. As shown in FIGS. 8 and 9 , the outrigger bracket 23 forms a substantially airtight space that is difficult to reach in by surrounding the periphery with a wall, and the main outrigger storage lock 11 is accommodated in the shown space.

The main leg storage lock 11 is provided with a lock plate 33, which can be freely rotatably supported by a fulcrum 32 toward a fulcrum 31 fixed inside the support bracket 23, and one end of the manipulation guide 9 and the return spring 30 is connected to One end 34 of the lock plate 33 . The other end of the return spring 30 is connected to the support plate 31 .

When the fulcrum 32 of the plate 33 is clamped, the end portion opposite to the end portion 34 is a locking end 36, and is fitted into a part formed in the combined part of the reinforcing plate 37 and the rear longitudinal wall 38. Bracket side slot 39 . Thus, the support-side slot 41 formed in the upper wall 40 of the main leg 12 in the upright state can be freely accessed.

The support-side slot 41 is consistent with the bracket-side slot 39 only when the main leg 12 is erected, so as to be able to cooperate with the locking end 36 of the locking plate 33 . If the locking end 36 engages the leg side slot 41, then the main leg 12 is locked so that it cannot rotate so that the main leg remains erect.

The return spring 30 usually rotates and pushes the locking plate 33 clockwise in FIG. 9 , so that the locking end 36 can be disengaged from the support side slot 41 to reach the unlocked position shown by the imaginary line in the figure. On the other hand, by overcoming the elastic force of the return spring 30 to make the lock plate 33 rotate counterclockwise, the locking end 76 is fitted into the leg side slot 41, and the operating wire rope 9 is in the position shown by the solid line in the figure. Location.

Reference numeral 42 in the figure denotes a rotation stopper, which can restrict the rotation of the lock plate 33 by contacting the reinforcement plate 37 at the locked position and the corner 43 of the support plate 31 at the open position.

Next, the function of this embodiment will be described. As shown in Figure 1, when the steering knob 8 in the storage box 6 is rotated in the direction of opening the main leg storage lock 11, the shutter 15 is opened while the main leg storage lock 11 is opened, and the main switch is opened. Insert the key not shown in the figure behind the key socket 14 of 3, just can travel after switching on switch.

In this way, since only the manipulation knob 8 is operated, the shutter 15 can be opened while the main leg storage lock 11 is opened, thereby simplifying the operation and improving the maneuverability. Therefore, the structure can be simplified and the cost can be reduced. In addition, similar to the opening of the shutter 15, if it is interlocked with the main leg storage lock 11 for the purpose of anti-theft, the anti-theft effect can be improved.

As shown in FIG. 1 , the steering handle lock plate 51 can also be moved through the shunt wire rope 50 from the joint 10 . Thus, since it is possible to directly fit the handle lock plate 51 with the slot 52 formed in the handle column 1 . It is thus possible to form the strength to operate the handle lock.

Also, since the stroke of the handle lock plate 51 is increased, the degree of freedom in setting the lever ratio is increased. Therefore, since the parts for the purpose of preventing theft are interlocked, the effect of preventing theft can be improved while improving the operability.

The present invention may have various modifications and applications not limited in the above embodiments. It is also possible to make the handle lock integrally formed on the main switch 3 . In addition, other various known structures can be adopted for the shutter opening/closing switch mechanism and the main leg storage lock.
