Hereinafter, the present invention will be described in detail with reference to the drawings showing embodiments.
1 and 2, a two-wheeled vehicle lock according to an embodiment of the present invention includes a short columnar lock body 2 having a locking hole portion 1 and an end portion 3a that is freely detachable from the locking hole portion 1. And a U-shaped shackle 3 that is inserted into the lock body 2 and pivotally pivoted at the other end 3b.

A key insertion part 15 is provided at one end 2 a of the lock body 2. A concave groove 21 is formed in the other end 2b of the lock body 2, and the other end 3b of the shackle 3 is pivoted so as to be fitted into the concave groove 21.
The lock body 2 has an outer shape formed by a substantially cylindrical outer cylinder 14, and a locking mechanism 18 is accommodated therein. The outer cylindrical body 14 is provided with a notch 22 that forms a part of the groove 21 and is connected to the open end of the outer cylindrical body 14. As a result, the U-shaped shackle 3 has a swing angle range of about 90 degrees.
The locking mechanism 18 switches between a locked state and an unlocked state in response to inserting and rotating the key 20 into the key insertion part 15.

The locking mechanism 18 will be described. The locking mechanism 18 includes a bottomed cylindrical rotating cylinder member 6 connected to the key insertion portion 15, and the outer cylinder body 14 as the rotating cylinder member 6 rotates. A slide member 9 that slides inside, a locking member 10 attached to the slide member 9 so as to move integrally with the slide member 9, and a resilient member 11 that resiliently biases the slide member 9 are provided. is doing.
The rotating cylinder member 6 is rotated with the rotation of the key 20 inserted into the key insertion part 15. An opening edge of the rotating cylinder member 6 is a cam edge 7.
The slide member 9 has a band plate-shaped follower portion 8 extending toward the rotating cylinder member 6 along the inner peripheral surface of the outer cylinder body 14. The distal end of the follower portion 8 is in contact with the cam edge 7 of the rotating cylinder member 6.
The resilient member 11 is a coil spring, and always urges the follower portion 8 of the slide member 9 toward the cam end edge 7 of the rotating cylinder member 6.
2 and 3, the end of the elastic member 11 opposite to the slide member 9 is in contact with the wall member 12. The wall member 12 includes a disk-shaped partition wall portion 12b that comes into contact with the elastic member 11, and a pair of leg portions 12a and 12a that are connected to the partition wall portion 12b.

  The locking hole portion 1 of the lock body 2 is formed by a hole provided at a position (position of the follower portion 8 of the slide member 9) between the locking member 10 and the rotating cylinder member 6 in the outer cylinder body 14. Is formed. A sealing receiving surface 5 of a sealing member 4 to be described later is formed at the opening end of the locking hole 1. The sealing receiving surface 5 is formed with a flat surface that is concentric and annular with the locking hole 1 (see FIG. 1).

Here, the U-shaped shackle 3 will be described. As shown in FIGS. 1 to 3, the other end 3 b of the U-shaped shackle 3 is provided with an insertion hole 19. A short columnar pivot shaft 13 press-fitted from the outside of the lock body 2 is inserted into the insertion hole 19, and the shackle 3 is pivotally supported by the pivot shaft 13. . The pivot shaft 13 is inserted through holes provided in the leg portions 12 a and 12 a of the wall member 12. Thereby, the movement of the wall member 12 inserted into the outer cylinder 14 is restricted. That is, the pivot shaft 13 has two functions: a function for pivotally supporting the shackle 3 and a function for regulating the movement of the wall member 12.
Further, a locking notch 17 is provided at one end 3 a of the shackle 3. The locking member 17 of the locking mechanism 18 is engaged with the locking notch 17 in the locked state.
A fitting groove 16 is formed at one end 3a of the shackle 3 at a position corresponding to the opening end of the locking hole 1 in the locked state. A seal member 4 is attached to the fitting groove 16.

The seal member 4 is a rubber O-ring, and has a size such that the outer diameter is larger than that of the shackle 3 when attached to the fitting groove 16. This prevents water traveling through the shackle 3 from collecting in the vicinity of the opening end of the locking hole 1 and makes it more difficult for water to enter the locking hole 1.
Further, the seal member 4 comes into contact with the sealing receiving surface 5 when the one end 3 a of the shackle 3 is inserted into the locking hole 1. Further, when a force is further applied to the shackle 3 from this contact state, the seal member 4 is elastically deformed to be pressed against the sealing receiving surface 5. In the two-wheeled vehicle lock of the present embodiment, the sealing member 4 is pressed against the sealing receiving surface 5, and locking is performed in a state where the locking hole 1 is completely sealed.

  Note that the present invention is not limited to the above-described embodiment, and the design can be changed without departing from the gist of the present invention. For example, in the present embodiment, the locking mechanism 18 is configured to be switched between the locked state and the unlocked state by inserting the key 20 into the key insertion portion 15 and rotating it, but the present invention is not limited thereto, An electronic two-wheeled vehicle lock that can be locked and unlocked with a contact type or non-contact type ID key, and the ID key can be re-registered with a simple operation even if the ID key is lost. Alternatively, the personal identification number button may be attached to the lock body and unlocked by pressing the correct personal identification number.

  As described above, the two-wheeled vehicle lock according to the present invention includes a short columnar lock body 2 having a lock hole portion 1, and one end 3 a is detachably inserted into the lock hole portion 1, while Since the end portion 3b is provided with the U-shaped shackle 3 that is pivotably pivoted, separation of the lock body 2 and the U-shaped shackle 3 can be prevented. As a result, the lock body 2 or the U-shaped shackle 3 is lost when being carried or mounted on a two-wheeled vehicle, as compared to a conventional two-wheeled vehicle lock that is designed to separate the lock body and the U-shaped shackle. Can be prevented, and the handling is excellent.

Also, a short columnar lock body 2 having a lock hole 1 and one end 3a are removably inserted into the lock hole 1 and the other end 3b is pivotally attached to the lock body 2. A U-shaped shackle 3, a seal member 4 is attached to one end 3 a of the shackle 3, and a sealing receiving surface 5 of the seal member 4 is annular at the opening end of the locking hole 1. Since it is formed with a flat surface, separation between the lock body 2 and the U-shaped shackle 3 can be prevented. As a result, the lock body 2 or the U-shaped shackle 3 is lost when carrying or attaching to a motorcycle as compared to a conventional two-wheeled vehicle lock that is designed to separate the lock body and the U-shaped shackle. Can be prevented, and the handling is excellent.
Further, the seal member 4 is attached to one end portion 3a of the shackle 3, and the sealing receiving surface 5 of the seal member 4 is formed with an annular flat surface at the opening end portion of the locking hole portion 1. In the locked state, water, dust, etc. can be prevented from entering the locking hole 1. Thereby, even when the two-wheeled vehicle lock has been locked outdoors for a long period of time and has been exposed to wind and rain, the locking mechanism 18 can be prevented from malfunctioning.
In addition, when the one end 3a of the shackle 3 is inserted into the locking hole 1, a structure that cannot be locked unless the sealing member 4 is deliberately pressed against the sealing receiving surface 5 can be unexpectedly formed. It can be prevented from being locked and has excellent handleability.
