BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a motorcycle wire locking device used to prevent theft of a motorcycle.

[0002]

2. Description of the Related Art As a conventional lock device used for preventing theft of a motorcycle (a bicycle, a bicycle with a motor, a motorcycle, etc.), there is a technology described in Japanese Patent Application Laid-Open No. 62-59783. In this technique, as shown in FIG. 11, a lock body 2 is provided at one end of an articulated wire 1 and an engagement portion 3 which is engaged with and disengaged from the lock body 2 is provided at the other end.

The lock body 2 has an outer cylinder 4 provided at one end of the articulated wire 1 provided with a lateral hole 5 opened to the side, and an end portion of a rotor 6a of a cylinder lock 6 fitted to the outer cylinder 4. , An L-shaped lock lever 7 is fixed. The engaging portion 3 inserted into the lateral hole 5 is provided with a projection 8 at the tip end. When the key 9 inserted into the key hole 6b of the cylinder lock 6 is operated in the locking or unlocking direction, the lock lever 7 is turned. The articulated wire 1 is locked or unlocked by being disengaged from the projection 8.

[0004]

Problems to be Solved by the Invention The following problems remain in the conventional motorcycle wire locking device as described above. (1) When unlocking the wire lock device, if the keyhole 6b does not face a position that is easy for the operator to operate,
The direction of the lock device must be changed by twisting the wire, and if the wire is an articulated wire, it cannot be twisted, so that it is difficult to insert the key 9 into the keyhole 6b.

(2) Since the lock body 2 and the wire 1 are integrated, the wire lock device for a motorcycle can be compactly stored.
It is inconvenient when carrying. The object of the present invention is to solve such a problem, and when unlocking the wire lock device, the keyhole can be easily turned to the operator, and the lock body and the wire are separated to be compact. The present invention provides a wire locking device for a motorcycle, which can be stored in a vehicle and is not likely to be unlocked illegally.

[0006]

In order to achieve the above-mentioned object, in the motorcycle wire locking device of the present invention, a wire insertion hole penetrates substantially at the center, a support shaft is provided at one end, and a cylinder is provided at the other end. A case in which a lock is fitted, and a wire housed in the case, one end of which is pivotally connected to the support shaft and the other end of a lever having a long hole for moving the holder, is engaged with a wire inserted through the wire insertion hole. A pair of latches, which are provided with a locking portion that is engaged with and disengaged from the mating portion and are urged in a direction to close the locking portion by a latch spring, and a sliding piece that slides along the inner wall surfaces of the pair of latches. the non-pushed portion provided at the end portion, the distal end of the arm projecting from extending to the holder moving elongated hole than the sliding piece is provided with a blocking portion for blocking the opening of the latch, the non-press by the holder spring Energized in the direction of the moving part and moves in the opposite direction In this position, the blocking portion is accommodated in the holder that overlaps the holder moving slot and the pair of latches, and one end is pivotally connected to the support shaft and the distal end of the pair of flexible arms is inserted from the wire insertion hole. A pressure-receiving piece pushed to the tip of the inserted wire is provided, and a wire insertion detection member provided with a stopper at the middle part of the flexible arm, which is engaged with and disengaged from the holder, and is fixed to a rotor of the cylinder lock. When the rotor is rotated in the unlocking direction, the plate drive cam includes a holder driving cam for pressing the non- pressing portion and a latch driving cam for pressing the latch in the opening direction.

[0007]

In the lock device constructed as described above, in the standby state where the cylinder lock is in the locked state and the tip of the wire is not inserted, the holder is at the position where the holder has been moved in the opposite direction to the urging state. The movement in the biasing direction is prevented by the stopper of the detection member. In this opposite direction,
Since the blocking portion of the holder overlaps the holder moving slot, it does not prevent the opening of the pair of latches.

Further, since the holder is at the position moved in the direction opposite to the bias, the non- pressing portion of the holder is separated from the holder driving cam of the locking plate cam, and the latch biased by the latch spring is It is closed. In such a standby state, when one end of the wire is inserted into the wire insertion hole of the case, the one end of the wire pushes open the engaging portion of the pair of latches, and the engaging portion of the wire engages the latch. When overlapped with the stop, the latch is closed and one end of the wire is locked to the locking device.

The pressure receiving piece of one flexible arm is pressed by one end of the inserted wire, and the flexible arm is bent and deformed, so that the engagement between the stopper of one flexible arm and the holder is released. However, since the other flexible arm does not bend, the stopper of the other flexible arm prevents the holder from moving in the biasing direction. Therefore, the blocking portion of the holder is located at a position overlapping the elongated hole for moving the holder, and does not prevent the opening of the pair of latches.

Next, when the other end of the wire is inserted into the wire insertion hole of the case, the other end of the wire pushes open the locking portions of the pair of latches, and the engaging portion of the wire locks the latches. When it overlaps with the part, the latch is closed, the other end of the wire is also locked by the lock device, and the pressure receiving piece of the other flexible arm is pressed, the flexible arm flexes and deforms, and both Since the engagement between the stopper of the flexible arm and the holder is released,
The holder moves in the biasing direction, and the blocking portion of the holder moves to the outer surface of the latch, thereby preventing the latch from being opened. Therefore, after both ends of the wire are locked, the holder prevents the pair of latches from opening, so that there is no danger that the pair of latches will open even if any external force or impact is applied to the wire.

When the key inserted into the cylinder lock is rotated in the unlocking direction, the holder driving cam of the plate cam pushes the non- pressing portion of the holder, and the holder moves in the direction opposite to the urging direction. Since the latch driving cams of the cams push the inner surfaces of the pair of latches and the latches are opened, the distal end of the wire can be removed. When the wire is removed, the flexible arm, which no longer presses the pressure-receiving piece at the tip of the wire, returns elastically, and the stopper engages with the holder. Return to the standby state.
