Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a stand device for a two-wheeled scooter that locks the stand in an upright position to prevent theft.

(Prior Art) Steering locks have conventionally been used to prevent two-wheeled scooters from being stolen. Additionally, a stand installed at the bottom of the vehicle body that can be raised and lowered and locked with a key switch has also been proposed (Japanese Patent Application Laid-Open No. 1983-1999-1).
(See example in No. 47281).

However, these conventional steering locks and stand locks require a key switch to be turned from the engine off position to the steering lock position or stand lock position, which is cumbersome to operate. Further, when the key is removed and the car is manually moved to an appropriate position and the stand is placed on the stand, the key operation must be performed again to lock the stand, making the operation very cumbersome. Therefore, there is a problem in that it is easy for the driver to forget these lock operations and leave the vehicle, reducing the anti-theft effect.

Also, since this stand lock is installed at the bottom of the vehicle, it may not be possible to secure sufficient minimum ground clearance.
There was also the problem that the vehicle was more easily hit by obstacles on the road and by stones thrown up by the front wheels.

(Purpose of the Invention) The present invention was made in view of the above circumstances, and the stand can be locked by raising the stand at the engine off position, eliminating the need for special operations to lock the stand. The first object is to provide a stand device which is highly effective in preventing theft without forgetting to put it on.

A second object is to provide a stand device for a two-wheeled scooter that can ensure sufficient minimum ground clearance despite the provision of a stand lock and can reduce the risk of being hit by obstacles or flying stones. .

(Structure of the Invention) According to the present invention, these objects include a frame having an inclined rising part that rises obliquely from the rear lower part of the footrest toward the lower part of the driver's seat, and a frame that is held by a pivot shaft on the inclined rising part. In a motorcycle equipped with a power unit and a stand that can be stored below the power unit, an interlocking member that allows the stand to rotate in an upright direction and rotates in one direction as the stand rotates in the storage direction. and a lock member for restricting rotation of the interlocking member in the one direction between the inclined rising portion below the pivot shaft and the front portion of the power unit, and the lock member restricts the rotation of the interlocking member in the one direction. This is achieved by a stand device for a two-wheeled scooter, which is characterized in that rotation in one direction is restricted by the engine-off position of a key switch.

(Example) The present invention will be explained in detail below based on the drawings.

Fig. 1 is a side view of a two-wheeled scooter to which an embodiment of the present invention is applied, Fig. 2 is an enlarged side view of the vicinity of the stand, Fig. 3 is a front view, and Figs. 4 and 5 are explanatory diagrams of its operation. 6 and 7 show a side view and a front view of the vicinity of the key switch, and FIG. 8 shows the dial of the key switch.

In FIG. 1, reference numeral 10 denotes a frame, a steering shaft 14 is inserted into a steering shaft tube 12 at the front end, a front wheel 16 is attached to its lower end, and a steering handle 18 is attached to its upper end. ing. The frame 10 includes an inclined upright portion 10c that rises obliquely from the lower rear of the footrest 10a toward the lower side of the driver's seat 10b. Reference numeral 20 designates a power unit in which an engine 22 and a transmission case 24 are assembled together, and a rear wheel 26 is attached to the rear end of the transmission case 24. The power unit 20 is attached to a bracket 28 fixed to the inclined upright portion 10c of the frame 10 so as to be swingable up and down by a pivot shaft 30 (see FIG. 2).

A stand 32 is made of a pipe bent into an inverted U shape, and its central portion is attached to the lower surface of the power unit 20 by a stand shaft 34.
This stand 32 can be raised and lowered between a storage position shown by imaginary lines in FIG. 2 and an upright position shown in reality. Further, a cam plate 36 is fixed to the upper part of the stand 32, which is bent so as to surround the front upper part of the stand shaft 34.

Reference numeral 38 denotes an auxiliary shaft, which is disposed in front of the stand shaft 34 and parallel to the stand shaft 34. That is, this auxiliary shaft 38 is housed in a box-shaped bracket 40 held by the pivot shaft 30 and stand shaft 34 (see FIG. 3). This auxiliary shaft 3
8 is a cam follower 4 that is in sliding contact with the cam plate 36;
2 and a lever 44 extending to the opposite side (forward) of the cam follower 42 are fixed to each other.
A tension spring 46 is stretched between the rotating end of the bracket 40 and a pin protruding from the inner surface of the bracket 40.

As a result, when the stand 32 is rotated in the storing direction, the cam follower 42 is pushed by the cam plate 36 as shown in FIG.
8. The lever 44 rotates clockwise while being pulled by the spring 46, and when the cam follower 42 gets over the cam plate 36, the cam follower 42 returns to its original position. A stand 32 is provided between the stand 32 and the power unit 20.
A stand spring (not shown) is attached that traverses the extension line of the stand shaft 34 as the stand 32 is raised and lowered, and the stand 32 is stabilized in the stored position by the stand spring.

Further, when the stand 32 is rotated in the standing direction, the cam plate 36 is moved to the cam follower 42 as shown in FIG.
Push up the auxiliary shaft 3 counterclockwise.
8. The lever 44 rotates in the same direction while pulling the spring 46.

That is, the cam follower 42, the auxiliary shaft 38, and the lever 44 form an interlocking member 48 that is interlocked with the raising and lowering of the stand 32. This interlocking member 48 is connected to the stand 3
When the stand 32 rotates in the standing direction, the stand 32 rotates counterclockwise in FIG. direction).

The lever 44 of this interlocking member 48 has an auxiliary shaft 38.
A stopper pin 50 is fixed in parallel with this.

Reference numeral 52 denotes a locking member, which is rotatably mounted on the auxiliary shaft 38 and can come into contact with the stopper pin 50. Note that this locking member 52 and interlocking member 4
8 is housed together with the bracket 40 in a space between the inclined upright portion 10c below the pivot shaft 30 and the front portion of the power unit 20 (see FIG. 1).

In FIGS. 1, 6, 7, and 8, a key switch 54 is fixed to the steering shaft cylinder 12. As shown in FIGS. The key switch 54 includes a steering lock mechanism that locks rotation of the steering shaft 14 when the key is in the LOCK position. Also this key switch 5
4. A lock pin 56 that interlocks with the key is provided at the lower end of the key. When the key is in the "OFF" and "LOCK" positions, this lock pin 56 is located downward as shown by the imaginary line in FIG. It comes to the solid line position. Here, "OFF" is the engine off position, and "LOCK" is the steering lock position. A bell crank 58 is pivotally supported on the side surface of the steering shaft cylinder 12 so as to be located below the key switch 54. This bell crank 58 is given a clockwise rotational habit in FIG. 6 by a tension spring 60. Reference numeral 62 designates a stopper for the bell crank 58, which stops the bell crank 58 with one (upper) rotating end of the bell crank 58 positioned behind the lock pin 56.

64 is a wire, both ends of the outer 64a are locked to a bracket 66 (FIGS. 6 and 7) fixed to the frame 10 and the box-shaped bracket 40, and the inner 64b is connected to the bell crank 58 and the lock. The rotating end of the member 52 is locked.

Next, the operation of this embodiment will be explained. When the key is in the "ON" or "LIGHT" position for night driving, the lock pin 56 of the key switch 54 is in the solid line position in FIG. For this reason, bell crank 5
8 is in a state where it can be rotated to the position shown by the imaginary line in FIG.
When the stand 32 is rotated in the storing direction in this state, the interlocking member 48 is rotated clockwise, and the stopper pin 50 pushes the locking member 52 clockwise (the fourth
figure). Therefore, the inner 64b of the wire 64 is pulled toward the stand 32, and the bell crank 58 is moved to the sixth position.
Rotate counterclockwise in the figure until it comes to the imaginary line position. When the stand 32 is near the storage position (imaginary line in FIG. 2), the cam follower 42 is disengaged from the cam plate 36, the interlocking member 48 is moved to the position shown in FIG. 2 by the spring 46, and the bell crank 58 is moved to the position shown in FIG. Return to the position indicated by the solid line in Figure 6. That is, at this time, the interlocking member 48 and the locking member 52 rotate as one.

If the stand 32 is rotated in the upright direction while keeping the key in this position, the interlocking member 48 will move the cam plate 3
6 (FIG. 5).
Since the bell crank 58 on the side of the steering shaft cylinder 12 has its return rotation amount limited by the stopper 62, no tensile force acts on the inner 64b of the wire 64. Therefore, the stopper pin 50, which is integral with the interlocking member 48, rotates while being separated from the locking member 52.
When the stand 32 approaches the upright position, the cam follower 42 separates from the cam plate 36, resulting in the state shown in FIG.

When the key is turned to the "OFF" or "LOCK" position, the lock pin 56 of the key switch 54 is placed within the rotation locus of one end of the bell crank 58. When the stand 32 is rotated in the standing direction in this state (see FIG. 5), the interlocking member 48 is rotated away from the locking member 52, and the stand 32 stands up. Further, when the stand 32 is rotated in the storage direction (see FIG. 4), the cam plate 36 pushes the cam follower 42 clockwise. However, at this time, the bell crank 58 is engaged with the lock pin 56, so it does not rotate counterclockwise in FIG.
It does not rotate clockwise in the figure. That is, the stopper pin 50 integrated with the interlocking member 48 is connected to the locking member 52.
The rotation of the interlocking member 48 is restricted. Therefore, the stand 32 is locked without rotating in the storage direction.

In this way, in this embodiment, the stand 32 can be locked simply by turning the key switch 54 to the engine-off position, and even after the key is removed, the stand 32 can be raised to lock the stand 32. There is no need to operate it, and it is easy to operate. Further, since the wire 64 can follow the key switch 54 wherever it is placed in the vehicle, there is a great degree of freedom in the installation position of the key switch 54, which is convenient in terms of design.

Further, in this embodiment, the key switch 54 is provided with a steering lock mechanism, and the stand 32 can be locked even in the steering lock state, so that the anti-theft effect of the vehicle is further enhanced.

(Effects of the Invention) As described above, the present invention provides an interlocking member that allows the stand to rotate in the upright direction and rotates in one direction when the stand rotates in the storage direction, and a member that locks the rotation in the other direction. The rotation of the interlocking member in the one direction by the lock member is restricted at the engine-off position of the key switch. Therefore, the stand can be locked in the upright position by simply turning the key switch to the engine-off position. Particularly at this time, since the stand can be rotated from the storage position to the standing position, the stand can be raised and locked without operating the key switch at all. In other words, even after removing the key, the stand can be raised and locked, making operation extremely easy. As a result, when the key is removed and the user leaves the vehicle, the stand is always locked in the upright position, resulting in an extremely high theft prevention effect.

In addition, since the interlocking member and locking member are housed in the space formed between the inclined rising part below the pivot shaft and the front part of the power unit, a sufficiently large minimum ground clearance can be secured, and obstacles and flying stones on the road can be secured. It will not damage them if it hits them.
