Here, the end of the first manual operation portion 41b extends to a position corresponding to the locking portion 41a of the locking bar 41.

Accordingly, when the user inserts the key 88 into the key hole 82 of the rotating part 81 and rotates the rotating part 81 in one direction (clockwise as in FIG. 11A), the first manual operation part ( 41b) releases the restriction between the locking bar 41 and the locking head 26 of the wire 22 while forcibly rotating the locking bar 41 in contact with the locking bar 41 and the second One end of the operation moving portion 41b contacts the inner surface of the ratchet bar 33 to rotate the ratchet bar 33 to release the restraint between the ratchet bar 33 and the ratchet gear 31.

Then, when the user rotates the rotating part 81 in the opposite direction (counterclockwise as in FIG. 11B), the first manual operating part 41b has an inner part that locks the battery cover 76 (not shown). Contact with the lock releases the lock.

On the other hand, as shown in Figure 12 and 13, the wire locking device of the present invention forms a closed circuit as a whole when the wire 22 is locked. That is, the locking head 26 of the wire 22 is inserted into the case through the wire insertion hole 14 and is electrically connected to the switching unit 53 of the controller 50. 54) hinge shaft 21, connecting member 24d, rotating drum 24, wire 22, locking head 26, switching part 53, and controller 50. .

Therefore, if a person with the intention of theft breaks or excessively pulls the wire 22 and a disconnection occurs in the closed circuit, the flow of the electrical signal through the closed circuit is lost, and the controller 50 detects the alarm (not shown). In addition to sending a signal to an external user, such as through wireless communication, and generates an alarm sound through the speaker (55).

The wire lock device of the present invention configured as described above operates as follows.

First, FIG. 5A illustrates an initial state before the wire 22 is drawn out, and the rotating drum 24 is positioned above the guide drum 23.

Subsequently, as shown in FIG. 5B, when the user pulls the locking head 26 of the wire 22 and pulls it out of the wire drawing hole 13 of the case 10, the wire 22 rotates the rotating drum 24. While rotating, it is released from the spiral wire winding groove 24a. At this time, the rotating drum 24 and the guide drum 23 rotate together about the hinge axis 21, and the rotating drum 24 slides downward along the axial direction of the guide drum 23. . That is, the rotating drum 24 draws out the wire 22 while making a spiral motion inside the drum housing 25.

In addition, since the ratchet gear 31 has a form in which the gears are inclined in one direction, the ratchet restricting portion 33a of the ratchet bar 33 is rotated when the rotating drum 24 and the guide drum 23 rotate. Rotate naturally while pushing outwards.

As the rotating drum 24 and the guide drum 23 rotate by the withdrawal of the wire 22, elastic force is accumulated in the spring spring 32 coupled to the upper side of the guide drum 23.

5C, when the locking head 26 of the wire 22 is inserted through the wire insertion hole 14, the inclined portion in front of the locking head 26 locks the locking bar 41. It enters while pushing the portion 41a naturally, and thus the locking bar 41 rotates outwardly about the locking bar rotation shaft 42. Subsequently, when the locking head 26 is fully inserted and the locking portion 41a of the locking bar 41 corresponds to the small diameter portion behind the locking head 26, the locking bar 41 of the torsion spring 43 The locking portion 41a is located behind the large diameter portion of the locking head 26 while being restored to the initial position by the action, and thus the locking head 26 is caught and restrained by the locking bar 41.

In addition, when the drawing operation of the wire 22 is no longer removed, rotational movement of the rotating drum 24 and the guide drum 23 does not occur, and the ratchet bar 33 has its locking portion 33a. As the gear of the cheat gear 31 is inserted therebetween, the ratchet gear 31 is restrained.

As described above, when the wire 22 is restrained by the locking bar 41, when the user sends a release operation signal to the controller 50 by using a remote controller or the like to release the lock state, the controller 50 may turn the cam drive motor 45. ) To operate the cam drive motor (45).

8 and 9, when the worm gear 46 is rotated by the operation of the cam driving motor 45, the reduction gear sets 47 engaged therewith are rotated, and the cam 44 is in one direction. Will rotate. As described above, when the cam 44 rotates in one direction, the ratchet bar 33 rotates about its rotational axis 34 (see FIG. 4A) to release the restrained state of the ratchet gear 31. At the same time, the locking bar 41 is rotated to release the locking portion 41a from the contact with the locking head 26, thereby releasing the restrained state of the wire 22.

As the restraint state of the ratchet gear 31 is released, the guide drum 23 and the rotating drum 24 are rotated in the opposite directions as before by the elastic force accumulated in the spring spring 32. Accordingly, the wire 22 is reinserted through the wire drawing hole 13 and wound around the wire winding groove 24a of the rotating drum 24. At this time, the rotating drum 24 is rotated along the guide drum 23 while rotating with the guide drum 23 in the state shown in Figure 5c in the state shown in Figure 5b.

When all of the wire 22 is wound inside the rotating drum 24, the cam driving motor 45 operates in reverse to return the cam 44 to its original state, and the latch bar 33 and the locking bar. The bars 41 are all returned to their original state.

On the other hand, when the remote control (not shown) or the controller 50 is fixed or the battery power is exhausted to operate the cam driving motor 45, the user may operate the key box assembly 80 as described with reference to FIG. 11A. It may be rotated to manually unlock the wire 22.

The wire locking device of the present invention can be used freely without fixing the case 10 to a frame of a vehicle such as a bicycle, but the adapter 91 is provided on one side of the case 10 as shown in FIGS. 1 and 2. It is also possible to connect and clamp the clamping band 92 to a frame such as a bicycle to fasten the bicycle or the like.

As described above, according to the present invention, when a person with the intention of theft breaks or forcibly pulls a wire, a disconnection occurs in an electrical circuit through the wire, and generates an alarm sound to the outside and sends it to the user through wireless communication. As a reminder, it is possible to respond quickly to theft and effectively prevent theft.

In addition, according to the present invention, since the rotating drum has a structure that moves up and down while rotating, the outer shape of the wire locking device, that is, the case can be made into a compact form such as a rectangular parallelepiped or a cylindrical shape corresponding to a frame such as a bicycle, Easy advantages can also be obtained.
