Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a lock for two-wheeled vehicles. More specifically, the present invention relates to a safe two-wheeled vehicle lock that prevents the lock from accidentally moving in the locking direction while the two-wheeled vehicle is running.

[Prior Art and Problems to be Solved] Conventionally, locks for motorcycles, such as motorcycle locks, can be locked by simply pushing in the axial direction when the lock is unlocked with a key. If the door is touched by a baggage such as a baggage, the cannuki may accidentally move suddenly in the direction of the lock. Depending on the degree to which the cannula moves, the spokes of the wheel may be damaged, and in some cases, the bicycle may fall, resulting in injury, or if there is a vehicle traveling alongside the bicycle when it falls, it may cause a tragic accident. If such a situation is left unaddressed, there are many problems in this day and age, where eradication of traffic accidents is strongly discouraged.
It is requested that safety measures be taken immediately.
Furthermore, in order to eliminate bicycle traffic accidents, on roads where bicycles can be ridden on sidewalks, pedestrians are often harmed by the above-mentioned falls.

In addition, even though the bicycle does not move in the direction of locking while riding, the bicycle stick protrudes sideways to the direction of travel, so there is no risk of harm to people walking right next to the bicycle. I can't say no. In order to meet these demands, the inventor of the present invention has diligently studied the structure of a safe two-wheeled vehicle lock that will not cause the lock to accidentally move in the direction of the lock, and will not cause any harm to people walking next to it while riding. As a result, we succeeded in creating a motorcycle lock that solved the above-mentioned problems when unlocking by making the cannula a special structure that allows it to be bent.

[Means for Solving the Problems] That is, the present invention includes: a case attached to a two-wheeled vehicle body; a cannula that is slidably inserted into the case in the axial direction and has a notch formed on the side surface; , a release spring that urges the cannula in the unlocking direction; a fixed guide plate that guides the movement of the cannula in the axial direction; and a fixed guide plate that guides the movement of the cannula in the axial direction; A lock for a two-wheeled vehicle, comprising: a cam plate having a locking piece that fits into a notch in the cantilever when the lock is locked; and a support shaft that rotatably supports the cam plate; A two-wheeled vehicle comprising a protrusion projecting to the outside of a case and a cannula body excluding the protrusion, the cannula body and the protrusion being rotatably connected via a connecting member. The main focus is on tablets for use.

[Function] As described above, in the motorcycle lock of the present invention, the lock is composed of a protrusion that projects outside the case when the lock is released, and the lock main body excluding this protrusion, and each of these parts is rotatable by the connecting member. Because it is connected to the lock, when locking, straighten the entire bar and press it in the locking direction, and insert the protruding part into the case, and the notch formed in the bar and the locking piece of the cam plate will connect. are mated together, making it easy to lock, and when unlocking,
When the cam plate is rotated to release the engagement between the locking piece and the notch, the cannula moves in the unlocking direction due to the biasing force of the release spring, so that the lock can be easily released. Further, when the lock is released, the protruding part rotatably connected to the cannula main body is protruded to the outside of the case, so that the protruding part can be rotated and bent.

[Example] Hereinafter, the present invention will be described based on drawings showing an example.

That is, the cannulae 20, 21, which are bent into a dogleg shape due to the elastic force of the spring 22 provided on the rod shaft 22a in the connecting part, are immediately stretched out with fingers, and the cannulae are turned in the locking direction (indicated by the arrow). 2
1. Push against the elastic force of the spring 23 housed in the spring 23. At this time, the stopper 26 provided on one side edge 21a of the cannula 21 moves along the guide slit 29 of the guide plate 27, stops at the locking side end of the guide slit 29, and moves the cannula 20, 21 in the locking direction. is stopped accordingly. On the other hand, as shown in FIG.
0 and 21, the locking piece 18 was pressed against the side wall of the cannula 21 by the elastic force of the spring 6, so it rotated in the direction of the arrow against the elastic force of the spring 6. However, as shown in FIG. 5, the locking piece 18 fits into the notch 25 provided in the canopy 21 at the position where the canopies 20 and 21 have finished moving, so that the spring 6 is not resilient. Due to the force, one support piece 19 of the spring 6 is pushed down and returned in the direction of the arrow. That is, the cannulae 20 and 21 are fixed in the locked position by the engagement between the notch 25 of the cannulae 21 and the locking piece 18 of the cam plate 15;
The spring 23 housed in the canopy 21 has a locking convex piece 24 erected inside the cannula 21 and an abutment piece 2 erected on the guide plate 27 toward the inside of the cannula.

Next, the key 32 is inserted through the slit 1d on the side surface of the lid body 1 in the locking/unlocking direction in FIG.
As shown in the figure, when the support shaft 9 is used as a fulcrum and is pushed down in the direction of the arrow, the cam plate 15 rotates to the same position as in FIG. As shown in FIG. 7, the cannula 21 is instantly moved into the lid body 1 in the unlocking direction (indicated by the arrow) and stored by the elastic force of the spring 23, as shown in FIG. A stopper 26 provided on one side of the guide plate 27 comes into contact with a receiving piece 26a provided at the unlocking side end of the guide groove 29, and a stopper 26 provided upright within the cannula 21 contacts a receiving piece 26a provided on the unlocking side end of the guide groove 29 on the guide plate 27.
4 comes into contact with the unlocking side end of the elongated hole 31, and the movement of the cannula 21 in the unlocking direction is stopped. The connecting portions of the cannulae 20 and 21 are located outside the lid body 1, and the cannulae 20 is bent in a direction substantially perpendicular to the unlocking direction, that is, along the side surface of the lid body 1, by the elastic force of the spring 22. FIG. 8 is a side view of the attachment 2 with some parts omitted when the lock is released. As shown in FIG. 6, when the key 32 is in the unlocked state, the locking piece 18 of the cam plate 15 contacts the side wall of the cannula 20 and the cam plate 15 itself remains rotated in the direction of the arrow. The supporting protrusions 10 and 12 provided on the surface of 5 prevent it from being removed.

[Effects of the invention] As described above, the motorcycle lock of the present invention has a structure in which the lock is bent on the outside of the case in the unlocked state, so that the lock may suddenly bend in the locking direction due to an unexpected external force. It can be said that it is an extremely safe lock because it never moves, and it does not cause any harm to people walking next to it while driving.
