At this time, the signal received by the antenna 7c, is used key signal immobilizer key or passive entry key used in motorcycle, the control board receives these key signal in the antenna which is the control unit 7 When the authentication is performed at 7a, a lock signal or an unlock signal is output from the control board 7a to the motor 5.

  Next, an example of the installation method and operation of the antitheft device 1 configured as described above will be described. First, the anti-theft device 1 is installed, for example, by fixing the frame 2 to a predetermined position on a concrete surface 3 of a parking lot at home or the like with an anchor bolt or the like, and connecting the power cord 7b of the control unit 7 to a commercial power source for home use. Is done. At this time, information on a motorcycle key to be used (for example, an immobilizer key) is stored in advance in the control circuit of the control board 7a, and the arms 8 and 9 of the lock member 4 are normally in the unlock position. As a result, the end faces of the flanges 8b and 9b of the arms 8 and 9 are largely opened.

  In this state, when the motorcycle is parked in the parking lot at home, the user slowly puts between the arms 8 and 9 that open the motorcycle wheel 13 (front wheel or rear wheel) while straddling the motorcycle. Then, as shown in FIG. 1, the hooks 8 b and 9 b of the arms 8 and 9 are positioned in a space formed inside the wheel 13 a of the wheel 13. In this state, the engine is turned off, the key is removed from the vehicle body, and this key is held over the antenna 7c portion of the antitheft device 1. When the key is held over, the signal transmitted from the key is received by the antenna 7c and input to the control board 7a, and whether or not it matches the key signal (key information) preset in the control circuit of the control board 7a. When the authentication is performed and the key signal is authenticated, a lock signal (for example, a forward rotation signal) is output from the control board 7a to the motor 5.

  When a lock signal is output from the control board 7a, the motor 5 rotates forward, and the flat gear 17 rotates in the forward direction via the flat gear 19 and the shaft 18. When the spur gear 17 rotates in the forward direction, the rack gears 15 and 16 meshing with the opposing positions in the diametrical direction move in the opposite directions B and C in FIG. As a result of the movement, the pair of arms 8 and 9 pivots about the pivot shaft 12 in the direction of the opposite arrow d in FIG. 4 and the end surfaces of the hook-shaped portions 8b and 9b of both arms 8 and 9 approach and lock. Set to position. By setting the arms 8 and 9 to the locked position, the lock member 4 is locked (engaged) with the wheel, and the anti-theft state (that is, the anti-theft device 1 is locked) is set. This is maintained as long as the arms 8 and 9 do not rotate in the direction of the arrows D and E which are the opening direction.

  On the other hand, when a motorcycle is used, the key signal is first authenticated by the control board 7a in the same manner as in the above-described lock by holding the key over the antenna 7c portion of the antitheft device 1. That is, when the key signal is authenticated, an unlock signal (for example, a reverse rotation signal) is output from the control board 7 a to the motor 5, the motor 5 rotates reversely, and the flat gear 17 reverses via the flat gear 19 and the shaft 18. Rotate in the direction. When the spur gear 17 rotates in the reverse direction, the rack gears 15 and 16 move in the direction of arrows B and C, which are unlock directions, and the movement of the rack gears 15 and 16 causes the pair of arms 8 and 9 to move the rotating shaft 12. Rotating in the direction of arrow D and E in the center, the hooks 8b and 9b of both arms 8 and 9 are separated, and the anti-theft device 1 is unlocked as shown in FIG. It is said. In this unlocked state, the locked state between the arms 8 and 9 (the lock member 4) and the wheel 13 is released, and the motorcycle can be removed from the anti-theft device 1 to perform normal traveling.

  That is, in the case of the anti-theft device 1, the lock member 4 is set from the unlock position to the lock position by the rotation of the motor 5, thereby locking the lock member 4 to the wheel 13 of the motorcycle and The locked state can be set, and the lock member 4 is set from the locked position to the unlocked position, whereby the unlocked state, which is a normal use state, can be set. Will be done automatically.

  As described above, in the anti-theft device 1 of the above embodiment, when the key signal of the immobilizer key is input to the control unit 7, the motor 5 is operated to lock the lock member 4 via the power transmission mechanism 6. Since the lock member 4 is set to the lock position or the unlock position, the lock member 4 can be easily moved electrically and the operability is excellent. The antitheft device 1 can be obtained.

  In particular, since a key signal by an immobilizer key set according to the motorcycle body is used as a signal for operating the motor 5, various keys of the motorcycle are locked and unlocked by the antitheft device 1. As a result, the operability can be improved, and unlocking and locking operations other than those set in advance can be prohibited, thereby improving the anti-theft property of the motorcycle.

  Further, the lock member 4 has a pair of arms 8 and 9 having a substantially L-shape in plan view and having hook-shaped portions 8b and 9b, and the base portions 8a and 9a of the arms 8 and 9 move in a direction in which they come in contact with and away from each other. As a result, the hook-shaped portions 8b and 9b are separated from each other and the lock member 4 is set to the unlocked position or the locked position, so that the lock member 4 can be configured to be opened and closed. The locked state and unlocked state of the antitheft device 1 can be easily grasped.

  Further, since the hooks 8b and 9b of the arms 8 and 9 of the lock member 4 are set inside the wheel 13a of the wheel 13 which is a part of the vehicle body, the lock member 4 is automatically set by the lock member 4. The wheel 13 of the motorcycle can be securely locked, and the wheel 13 of the motorcycle can be easily set on the lock member 4 that is open, for example. Further, by using the motor 5 and the guide roller 20 and the like, the linear motion of the rack gears 15 and 16 becomes good, and the arms 8 and 9 of the lock member 4 can be smoothly opened and closed. As a result, the operability of the antitheft device 1 can be improved, and the antitheft device 1 excellent in usability can be provided.

  Further, the frame 2 of the anti-theft device 1 is covered with the frame cover 2a and is firmly fixed to the concrete surface 3 or the like of the parking lot, and the arms 8 and 9 of the lock member 4 are firmly made by metal cutting or the like. Since it is formed, easy movement and breakage are prevented, and the anti-theft property of the motorcycle by the anti-theft device 1 can be sufficiently enhanced. Further, since the rotation operation of the lock member 4 is performed by forward / reverse rotation of the motor 5, the power transmission mechanism 6 can be simply configured, and the cost of the antitheft device 1 can be reduced.

In the above embodiment, the motor 5 is operated via the control unit 7 by the key signal of the immobilizer key of the motorcycle. However, the present invention is not limited to this example, and the passive set in the motorcycle. it is of course also possible to use a key signal of the entry key. Moreover, in the said embodiment, although the information of the key used previously was memorize | stored in the control part 7, it became possible to use a specific key. In the case of owning a motorcycle, key information (that is, a plurality of key signals) of each motorcycle can be stored.

  Furthermore, in the said embodiment, although it comprised so that the lock member 4 of the antitheft device 1 might be attached to the wheel 13 as a part of the vehicle body of a motorcycle, as a part of the vehicle body concerning this invention, it is other than the wheel 13 It can be applied to the frame itself. Further, the overall configuration of the lock member, the configuration of the arm and the power transmission mechanism, the operation method of the motor, and the like in the above embodiment are also examples. For example, a plurality of lock members are arranged in parallel and controlled by individual control units. Thus, the configuration can be appropriately changed without departing from the gist of the present invention, such as a configuration in which a plurality of motorcycles can be locked.
