There is.

  Therefore, in view of the above-described situation, the present invention intends to solve the problem that the motorcycle is unexpectedly locked while the motorcycle is in operation while being configured to be locked when the stand is stood down from a motorcycle such as a bicycle or a motorcycle. The object of the present invention is to provide a highly safe locking device for a two-wheeled vehicle because the locking rod does not enter between the spokes even if the stand swings downward.

  In order to solve the above-described problem, a locking device for a motorcycle according to the present invention is a ring-shaped device that is fixed to a vehicle body with both ends facing each other so as to have an opening inside a rim of a rear wheel of a motorcycle. A casing and a locking bar supported by the casing so as to be able to protrude and retract, and the locking bar is inserted between the spokes of the rear wheel so that the locking bar crosses between both ends of the casing. A ring lock for preventing the rotation of the rear wheel, and a rear position provided on the rear wheel side of the two-wheeled vehicle so as to support the vehicle body in order to make the two-wheeled vehicle self-supported and not to interfere with the traveling A projecting piece that is capable of swinging around a swing support shaft within a predetermined swing angle range between two positions of the jumped-up position and projecting sideways to a predetermined position spaced from the swing support shaft toward the free end side And a stand provided with A gear having a notch portion with a circumferential angle range smaller than a predetermined swing angle range of the tund and having a circumferential end abutting against a protruding piece of the stand and extending in the circumferential direction about the swing support shaft A first gear body that swings around the swing support shaft, a base that is attached to a vehicle body around the axle of the rear wheel, and a rack that is slidably supported by the base, A second gear body that is rotatably supported by the base body and meshes with the gear portion of the first gear body, and a third gear body that is rotatably supported by the base body and meshes with the second gear body and the rack body. And a cable body having one end connected to the locking rod of the ring lock and the other end connected to the rack body, and from the position where the stand is flipped up backward to the standing position. When swinging, The protruding piece of the stand comes into contact with one circumferential edge of the notch portion of the first gear body at an intermediate swing angle within a predetermined swing angle range, and further, the stand is moved closer to the standing position. The gear portion of the first gear body swings with the swinging operation, the second gear body meshing with the gear portion swings, and the third gear body meshing with the second gear body. Oscillates, the rack body meshing with the third gear body slides and the strip body is pulled, so that the locking bar of the ring lock is driven, and the stand is oscillated to the upright position. And the ring lock is in a locked state.

According to such a configuration, when the stand is lowered from the two-wheeled vehicle, the one end portion of the locking rod is a ring lock by the gear transmission mechanism including the first gear body, the second gear body, the third gear body, and the rack body. The cable is connected to the rack body and the other end is connected to the rack body, and the locking bar is driven and the ring lock is always locked. The trouble of locking operation can be saved.
In addition, the first gear body is formed with a notch portion having a circumferential angle range smaller than the predetermined swing angle range of the stand, and the protruding piece of the stand is formed at the circumferential edge of the notch portion of the first gear body. Even if the first gear body does not swing even if it swings to the abutting intermediate swing angle, even if the stand unexpectedly swings downward at an angle within the intermediate swing angle during operation of the two-wheeled vehicle, the strip body Is not pulled, and since the locking bar of the ring lock is not driven, the locking bar does not enter and get caught between the spokes, so that safety is improved.

Here, it is preferable that the intermediate swing angle is a swing angle at which the rear wheel is lifted from the ground when the stand is swung from the position where the stand is flipped up to the standing position. .
According to such a configuration, since the rope body is not pulled by the gear transmission mechanism and the locking bar is driven while the rear wheel of the two-wheeled vehicle is in contact with the ground, the safety is further improved.

The second gear body includes a small-diameter gear portion and a large-diameter gear portion that are coaxially integrated, the small-diameter gear portion meshes with a gear portion of the first gear body, and the large-diameter gear portion is It is preferable to mesh with the third gear body.
According to such a structure, it is necessary to ensure the pulling stroke of the rope body for bringing the ring lock into the locked state at the swing angle that swings the stand from the intermediate swing angle to the standing position. In the gear transmission mechanism, the displacement is enlarged by the ratio of the number of teeth of the small-diameter gear portion to the number of teeth of the large-diameter gear portion of the second gear body (ratio of the pitch circle diameter). At the same time, since the distance between the first gear body and the second gear body can be reduced, the gear transmission mechanism can be formed more compactly.

Further, a long hole extending in the longitudinal direction is formed in the rack body, and an engaging body that engages with the long hole of the rack body and is movable in the long hole is connected to the other end portion of the strip body. This is preferable.
According to such a configuration, since the engaging body that engages with the long hole of the rack body can move within the long hole, the stand is connected to the locking rod of the ring lock even in the state where the stand is in the rearward raising position. Since the operation piece can be manually operated and locked, it is possible to deal with parking in a bicycle parking lot for two-wheeled vehicles that require parking without raising the stand.

  As described above, according to the two-wheeled vehicle locking device according to the present invention, since it is configured to be locked when the stand is lowered after getting off the two-wheeled vehicle, it is possible to prevent forgetting the locking and to save the trouble of the locking operation. The first gear body is formed with a notch portion having a circumferential angle range smaller than a predetermined swing angle range of the stand, and the protruding piece of the stand has one circumference of the notch portion of the first gear body. Since the first gear body does not swing even if it swings to the intermediate swing angle that contacts the direction edge, the stand unexpectedly swings downward within the intermediate swing angle during operation of the two-wheeled vehicle. However, the cord body is not pulled, and the locking bar of the ring lock is not driven, so that the locking bar does not enter and get caught between the spokes.
