[60] In addition, a case 320 is integrally coupled to rear portions of the housing 310 by using at least one or more bolts, pieces, or the like so as to be closely fixed to the rear portions of the housing.

[61] In addition, the housing 310 and the case 320 can be formed in a box shape, a cylindrical shape, or other various shapes. Preferably, in the motorcycle anti- theft lock device 300 according to the present invention, the housing 310 and the case 320 are formed in a box shape.

[62] The space portion 311 of the housing 310 is constructed so that the power transmission means 500, the locking bar 520, the printed circuit board 420, and the position adjusting sensor 422 can be fixed therein.

[63] The exit hole 321 of the case 320 which is coupled to the rear portions of the housing

310. When a driver touches a touch key 411 to a touch sensor 412, when the driver touches a card key 413 to a card key sensor 414, when the driver manipulates a remote controller 416, or when a password sensor 415 senses a password input by the driver, the printed circuit board 420 receives an on/off signal. When the printed circuit board 420 applies a power to the power transmission means 500 so as for the locking bar 520 to be moved in the forward and backward directions, it is possible to prevent vibration and shaking of the locking bar 520 that is caused from the driving and infinitesimal vibration of the normal/reverse rotation motor 510, the pinion gear 512, and the rack gear 521.

[64] The sensor unit 410 senses connection and disconnection of a power which can move the locking bar 520 of the power transmission means 500 fixed to the space portion 311 of the housing 310.

[65] The sensor unit 410 has functions of sensing touching of a touch key 411 through a touch sensor 412, sensing touching of a card key 413 through a card key sensor 414, sensing input of a password input by a driver through a password sensor 415, transmitting an on/off signal to the printed circuit board 420 through manipulation of a remote controller 416.

[66] The printed circuit board 420 has functions of receiving the on/off signal applied from the sensor unit 410 and controlling connection and disconnection of the power which can move the locking bar 520 of the power transmission means 500 in forward and backward directions.

[67] Referring to Figs. 1 to 12, the sensor unit 410 of the motorcycle anti-theft lock device

300 according to the present invention is provided to the outer case 200 of the motorcycle. The sensor unit 410 includes the touch sensor 412 which transmits the on/ off signal according to the touching of the touch key 411 which is externally inserted and the printed circuit board 420 which controls the connection and disconnection of the power which moves the locking bar 520 according to the on/off signal transmitted from the touch sensor 412.

[68] The touch key 411 is constructed so as to be touched to or detached from the touch sensor 412. Since the construction of the touch key 411 is well known, detailed description thereof will be omitted.

[69] The touch sensor 412 is provided to the outer case 200 of the motorcycle. When a driver touches the touch key 411 to the touch sensor 412, the touch sensor 412 senses the touching and transmits the on/off signal to the printed circuit board 420 provided to the lock device 300 through a cable.

[70] The printed circuit board 420 receives the on signal from the touch sensor 412 to apply the power to a normal/reverse rotation motor 510 which is a component of the power transmission means 500. By the applied power, a pinion gear 512 coupled to a fixing shaft 511 of the normal/reverse rotation motor 510 is reversely rotated.

[71] The locking bar 520 having a rack gear 521 engaged with the pinion gear 512 is moved forwards. When the locking bar 520 is extracted from the insert hole 110 of the steering-handle rotating shaft 100 of the motorcycle, the locking bar 520 is unlocked from the steering-handle rotating shaft 100, so that the motorcycle can be driven.

[72] On the contrary, when the driver touches the touch key 411 to the touch sensor 412, the printed circuit board 420 receives the off signal from the touch sensor 412 to apply the power to the normal/reverse rotation motor 510 which is a component of the power transmission means 500. By the applied power, the pinion gear 512 coupled to the fixing shaft 511 of the normal/reverse rotation motor 510 is normally rotated.

[73] The locking bar 520 having the rack gear 521 engaged with the pinion gear 512 is moved backwards. When the locking bar 520 is inserted into the insert hole 110 of the steering-handle rotating shaft 100 of the motorcycle, the locking bar 520 is locked with the steering-handle rotating shaft 100, so that the motorcycle can be stopped.

[74] Therefore, when the driver touches the touch key 411 to the touch sensor 412 of the outer case 200, the printed circuit board 420 that receives an on/off signal from the touch sensor 412 controls connection and disconnection of a power to the power transmission means 500, so that the locking bar 520 of the power transmission means 500 is moved in the forward and backward directions to be locked and unlocked to the insert hole 110 of the steering-handle rotating shaft 100. Accordingly, it is possible to prevent theft of the motorcycle.

[75] Referring to Figs. 6 to 12, the sensor unit 410 of the motorcycle anti-theft lock device

300 according to the present invention is provided to the outer case 200 of the motorcycle. The sensor unit 410 includes the card key sensor 412 which senses the on/ off signal according to the touching of the card key 413 carried by the driver and the printed circuit board 420 which controls the connection and disconnection of the power which moves the locking bar 520 according to the on/off signal transmitted from the card key sensor 414.

[76] The card key 413 is constructed so as to be touched to or detached from the card key sensor 414. Since the construction of the card key 413 is well known, detailed description thereof will be omitted.

[77] The card key sensor 414 is provided to the outer case of the motorcycle. When the driver touches the card key 413 to the card key sensor 414, the card key sensor 414 senses the touching and transmits the on/off signal to the printed circuit board 420 provided to the lock device 300 through a cable.

[78] The printed circuit board 420 receives the on signal from the card key sensor 414 to apply the power to the normal/reverse rotation motor 510 which is a component of the power transmission means 500. By the applied power, the pinion gear 512 coupled to the fixing shaft 511 of the normal/reverse rotation motor 510 is reversely rotated.

[79] The locking bar 520 having the rack gear 521 engaged with the pinion gear 512 is moved forwards. When the locking bar 520 is extracted from the insert hole 110 of the steering-handle rotating shaft 100 of the motorcycle, the locking bar 520 is unlocked from the steering-handle rotating shaft 100, so that the motorcycle can be driven.

[80] On the contrary, when the driver touches the card key 413 to the card key sensor 414, the printed circuit board 420 receives the off signal from the card key sensor 414 to apply the power to the normal/reverse rotation motor 510 which is a component of the power transmission means 500. By the applied power, the pinion gear 512 coupled to the fixing shaft 511 of the normal/reverse rotation motor 510 is normally rotated.

[81] The locking bar 520 having the rack gear 521 engaged with the pinion gear 512 is moved backwards. When the locking bar 520 is inserted into the insert hole 110 of the steering-handle rotating shaft 100 of the motorcycle, the locking bar 520 is locked with the steering-handle rotating shaft 100, so that the motorcycle can be stopped.

[82] Therefore, when the driver touches the card key 413 to the card key sensor 414 of the outer case 200, the printed circuit board 420 that receives an on/off signal from the card key sensor 414 controls connection and disconnection of a power to the power transmission means 500, so that the locking bar 520 of the power transmission means 500 is moved in the forward and backward directions to be locked and unlocked to the insert hole 110 of the steering-handle rotating shaft 100. Accordingly, it is possible to prevent theft of the motorcycle.

[83] Referring to Figs. 7 to 12, the sensor unit 410 of the motorcycle anti-theft lock device

The sensor unit 410 includes the password sensor 415 which senses input of a password which is previously registered by the driver and the printed circuit board 420 which controls the connection and disconnection of the power which moves the locking bar 520 according to the on/off signal transmitted from the password sensor 415.

[84] The password sensor 415 is provided to the outer case 200 of the motorcycle. When the driver inputs the password which is previously registered, the password sensor 412 senses the input and transmits the on/off signal to the printed circuit board 420 provided to the lock device 300 through a cable.

[85] The printed circuit board 420 receives the on signal from the password sensor 415 to apply the power to a normal/reverse rotation motor 510 which is a component of the power transmission means 500. By the applied power, the pinion gear 512 coupled to the fixing shaft 511 of the normal/reverse rotation motor 510 is reversely rotated.

[86] The locking bar 520 having a rack gear 521 engaged with the pinion gear 512 is moved forwards. When the locking bar 520 is extracted from the insert hole 110 of the steering-handle rotating shaft 100 of the motorcycle, the locking bar 520 is unlocked from the steering-handle rotating shaft 100, so that the motorcycle can be driven.

[87] On the contrary, when the password sensor 415 senses the input of the password which is previously registered by the driver, the printed circuit board 420 receives the off signal from the password sensor 415 to apply the power to the normal/reverse rotation motor 510 which is a component of the power transmission means 500. By the applied power, the pinion gear 512 coupled to the fixing shaft 511 of the normal/ reverse rotation motor 510 is normally rotated. [88] The locking bar 520 having the rack gear 521 engaged with the pinion gear 512 is moved backwards. When the locking bar 520 is inserted into the insert hole 110 of the steering-handle rotating shaft 100 of the motorcycle, the locking bar 520 is locked with the steering-handle rotating shaft 100, so that the motorcycle can be stopped.

[89] Therefore, when the password sensor 415 of the outer case 200 senses input of the password that is previously registered by the driver, the printed circuit board 420 that receives an on/off signal from the password sensor 415 controls connection and disconnection of a power to the power transmission means 500, so that the locking bar 520 of the power transmission means 500 is moved in the forward and backward directions to be locked and unlocked to the insert hole 110 of the steering-handle rotating shaft 100. Accordingly, it is possible to prevent theft of the motorcycle.

[90] Referring to Figs. 8 to 12, the sensor unit 410 of the motorcycle anti-theft lock device

300 according to the present invention is provided to the outer case 200 of the motorcycle. The sensor unit 410 includes the printed circuit board 420 which receives the on/off signal through the remote controller 416 carried by the driver and controls the connection and disconnection of the power which moves the locking bar 520 in an forward and backward directions with respect to the insert hole of the steering-handle rotating shaft 100.

[91] Namely, through the manipulation of the remote controller 416 carried by the driver, the on/off signal is received by the printed circuit board 420 provided to the lock device 300.

[92] The printed circuit board 420 receives the on signal from the remote controller 416 to apply the power to the normal/reverse rotation motor 510 which is a component of the power transmission means 500. By the applied power, the pinion gear 512 coupled to the fixing shaft 511 of the normal/reverse rotation motor 510 is reversely rotated.

[93] The locking bar 520 having a rack gear 521 engaged with the pinion gear 512 is moved forwards. When the locking bar 520 is extracted from the insert hole 110 of the steering-handle rotating shaft 100 of the motorcycle, the locking bar 520 is unlocked from the steering-handle rotating shaft 100, so that the motorcycle can be driven.

[94] On the contrary, the printed circuit board 420 receives the off signal through the manipulation of the remote controller 416 to apply the power to the normal/reverse rotation motor 510 which is a component of the power transmission means 500. By the applied power, the pinion gear 512 coupled to the fixing shaft 511 of the normal/ reverse rotation motor 510 is normally rotated.

[95] The locking bar 520 having the rack gear 521 engaged with the pinion gear 512 is moved backwards. When the locking bar 520 is inserted into the insert hole 110 of the steering-handle rotating shaft 100 of the motorcycle, the locking bar 520 is locked with the steering-handle rotating shaft 100, so that the motorcycle can be stopped. [96] Therefore, when the driver manipulates a remote controller 416 carried by the driver, the printed circuit board 420 that receives an on/off signal controls connection and disconnection of a power to the power transmission means 500, so that the locking bar 520 of the power transmission means 500 is moved in the forward and backward directions to be locked and unlocked to the insert hole 110 of the steering-handle rotating shaft 100. Accordingly, it is possible to prevent theft of the motorcycle.

[97] Referring to Figs. 1 to 5, the printed circuit board 420 of the motorcycle anti-theft lock device 300 according to the present invention is provided with an impact sensor 421 which senses external impact to the locking bar 520 locked into the insert hole 110 of the steering-handle rotating shaft 100 of the motorcycle and transmits a signal to an alarm unit 600 or a blinking lamp 700.

[98] Namely, the impact sensor 421 is further provided to the printed circuit board 420 which is assembled in the housing 310 which is a component of the lock device 300. In the state that the locking bar 520 of the power transmission means 500 is locked into the insert hole 110 of the steering-handle rotating shaft 110 of the motorcycle, the impact sensor 421 senses the external impact to the locking bar 520 or the motorcycle and transmits a signal to the alarm unit 600 or the blinking lamp 700, so that the driver can check an alarm sound or a light. Accordingly, it is possible to prevent theft of the motorcycle.

[99] Referring to Figs. 1 to 4, the housing 310 of the motorcycle anti-theft lock device

300 according to the present invention is provided with a supporting hole 312 which is formed corresponding to the exit hole 321 to prevent vibration of the locking bar 520 which is caused from the forward movement of the locking bar 520 driven by the power transmission means 500.

[100] Namely, the supporting hole 312 is provided so as to support the locking bar 520 to the housing 310 which is a component of the lock device 300. Therefore, the supporting hole 312 is formed to the case 320 corresponding to the exit hole 321, so that the supporting hole can prevent infinitesimal vibration which is caused from the forward movement of the locking bar 520 driven by the power transmission means 500. Accordingly, it is possible to prevent destruction of parts of the power transmission means 500.

[101] Referring to Figs. 1 to 12, the power transmission means 500 of the motorcycle anti- theft lock device 300 according to the present invention is provided with the pinion gear 512 which is disposed in the space portion 311 to be coupled with a circumference of the fixing shaft 511 which is upwardly protruded from the normal/ reverse rotation motor 510 and the locking bar 520 having the rack gear 531 which is rotated through engagement with the pinion gear 512 and closely attached around an inner circumference of the supporting hole 312 and the exit hole 321 to be moved in the forward and backward directions so as to be inserted into and extracted from the insert hole 110.

[102] More specifically, when the touch sensor 412 senses the touching of the touch key 411, when the card key sensor 414 senses the touching of the card key 413, when the password sensor 415 senses input of the password of the driver, or when the remote controller 416 is manipulated, the printed circuit board 420 receives the on signal.

[103] When the power is applied to the normal/reverse rotation motor 510 according to the on signal received from the printed circuit board 420, the normal/reverse rotation motor 510 is reversely rotated by the applied power.

[104] Next, the locking bar 520 having the rack gear 521 engaged with the pinion gear 512 which is coupled with the fixing shaft 511 of the normal/reverse rotation motor 510 is moved in the forward direction to penetrate the supporting hole 312 and the exit hole 321 and be extracted from the insert hole 110 of the steering-handle rotating shaft 100, so that the locking bar is unlocked. Accordingly, the motorcycle is unlocked.

[105] On the contrary, when the touch sensor 412 senses the touching of the touch key 411, when the card key sensor 414 senses the touching of the card key 413, when the password sensor 415 senses input of the password of the driver, or when the remote controller 416 is manipulated, the printed circuit board 420 receives the off signal.

[106] When the power is applied to the normal/reverse rotation motor 510 according to the off signal input to the printed circuit board 420, the normal/reverse rotation motor 510 is normally rotated by the applied power.

[107] Next, the locking bar 520 having the rack gear 521 engaged with the pinion gear 512 which is coupled with the fixing shaft 511 of the normal/reverse rotation motor 510 is moved in the backward direction to penetrate the supporting hole 312 and the exit hole 321 and be inserted into the insert hole 110 of the steering-handle rotating shaft 100, so that the locking bar is locked. Accordingly, the motorcycle is locked.

[108] Therefore, the power transmission means 500 is disposed in the housing 310 which is a component of the lock device 300, so that the printed circuit board 420 which receives an on/off signal of the sensor unit 410 applies a power to the power transmission means 500 so as for the locking bar 520 to be moved in forward and backward directions through driving of a pinion gear 512 and a rack gear 521. Accordingly, the locking bar 520 can be locked and unlocked to the insert hole 110 of the steering-handle rotating shaft 100.

[109] Referring to Figs. 1 to 5, the motorcycle anti-theft lock device 300 according to the present invention is provided with a position adjusting sensor 422 which senses the locking bar 520 in a process of moving the locking bar 520 with respect to the insert hole 110 of the steering-handle rotating shaft 100 through the driving of the normal/ reverse rotation motor 510 so as for the locking bar to be moved or fixed in a suitable moving distance.

[110] More specifically, in a case where the driver desires to lock the steering handle of the motorcycle, at the time that the locking bar 520 is inserted into the insert hole 110 of the steering-handle rotating shaft 100 through the driving of the power transmission means 500, the position adjusting sensor 422 senses the locking bar, and after the locking bar 520 is moved in a suitable moving distance, a signal is transmitted to the position adjusting sensor so as to control movement of the locking bar 520.

[I l l] In addition, in a process of moving the locking bar 520 in the backward direction, when the locking bar is not fixed to the insert hole 110, a signal is transmitted to the position adjusting sensor 422 so as for the locking bar 520 provided to the power transmission means 500 to be returned to an initial position.

[112] Therefore, since the printed circuit board 420 assembled in the housing 310 which is a component of the lock device 300 is provided with the position adjusting sensor 422, the locking bar 520 is moved in the backward direction through the driving of the power transmission means 500, and the position adjusting sensor 422 senses the locking bar in a process of moving the locking bar with respect to the insert hole 110 of the steering-handle rotating shaft 100 so as for the locking bar to be moved or fixed in a suitable moving distance.

[113] Referring to Figs. 1 to 12, the motorcycle anti-theft lock device 300 according to the present invention is provided with a cover 330 which is disposed in front of the housing of the lock device 300 so as to prevent destruction of the locking bar 520 of the power transmission means 500.

[114] Namely, since the cover 330 is not further provided in front of the housing 310, there is a problem in that the locking bar 520 that is moved in the forward direction is externally protruded through the inner circumference of the supporting hole formed in the housing 310.

[115] In a case where the lock device 300 is installed in a large-sized motorcycle (125cc or more), when external impact is exerted on the locking bar 520, the locking bar 520 may be destructed. In order to solve the problem of destruction and improve outer appearance, the cover 330 is preferably assembled in front of the housing 310 which is to be installed in the motorcycle.

[116] Referring to Figs. 1 to 12, in the motorcycle anti-theft lock device 300 according to the present invention, a lock-device mounting plate 800 which is provided with a fixing hole 810 so as for the locking bar 520 of the power transmission means 500 to move in the forward and backward directions is disposed between the steering-handle rotating shaft 100 and the lock device 300.

[117] Since the lock-device mounting plate 800 is further disposed between the steering- handle rotating shaft 100 and the lock device 300, the locking bar 520 of the power transmission means 500 penetrates the fixing hole 810 of the lock-device mounting plate 800 to be engaged and locked into the insert hole 520 of the steering-handle rotating shaft 100 in forward and backward movement of the locking bar 520, so that it is possible to firmly fix the lock device 300, the lock-device mounting plate 800, and the steering-handle rotating shaft 100.

[118] Referring to Figs. 10 to 12, in the motorcycle anti-theft lock device 300 according to the present invention, the lock-device mounting plate 800 is fixed to the steering- handle rotating shaft 100 through a double-sided adhesive tape or welding.

[119] Since the lock-device mounting plate 800 is fixed to the steering-handle rotating shaft 100 through the double-sided adhesive tape or the welding, it is possible to simplify assembling processes and reduce production costs such as personnel expenses.

[120] Hereinafter, locking and unlocking processes of the motorcycle anti-theft lock device according to the present invention will be described.

[121] Fig. 11 is a view showing a locking process of the motorcycle anti- theft lock device according to the present invention. Fig. 12 is a view showing an unlocking process of the motorcycle anti-theft lock device according to the present invention.

[122] Referring to Figs. 1 to 11, in the locking process of the motorcycle anti-theft lock device 300 according to the present invention, when the driver touches the touch key 411 to the touch sensor 412, the touch sensor 412 senses the touching and transmits the off signal to the printed circuit board 420. Next, the printed circuit board 420 applies the power to the normal/reverse rotation motor 510 so as to drive the normal/reverse rotation motor 510.

[123] Next, the locking bar having the rack gear 521 engaged with the pinion gear 512 which is coupled with the fixing shaft 511 of the normal/reverse rotation motor 510 is moved in the backward direction.

[124] Next, by the normal rotation of the pinion gear 512, the locking bar 520 is moved in the backward direction through the inner circumference of the supporting hole 312 of the housing 310 and the exit hole 321 of the case 320. The locking bar 520 is inserted in to the fixing hole 810 of the lock-device mounting plate 800 and the insert hole 110 of the steering-handle rotating shaft 100 of the motorcycle, so that the lock device is locked.

[125] In addition, if the locking bar 520 is insecurely coupled with a circumferential portion of the insert hole 110 of the steering-handle rotating shaft 100, the position adjusting sensor 422 transmits a signal to the normal/reverse rotation motor 510, and the position adjusting sensor 422 senses the movement of the locking bar 520 with respect to the insert hole 110. When the locking bar 520 is moved along an inner circumference of the insert hole 110 to be closely fixed to an end thereof, the position adjusting sensor 422 senses the movement of the locking bar and transmits a signal so as for the normal/reverse rotation motor 510 to be stopped, so that the motorcycle anti- theft lock device is locked.

[126] On the other hand, if the locking bar 520 is insecurely coupled with the circumferential portion of the insert hole 110 of the steering-handle rotating shaft 100, the position adjusting sensor 422 transmits a signal to the normal/reverse rotation motor 510, and the locking bar 520 is returned to an initial position. By the above processes, the locking bar 520 is inserted into the insert hole of the steering-handle rotating shaft 520 of the motorcycle, so that the motorcycle anti-theft lock device is locked.

[127] Referring to Figs. 1 to 12, in the unlocking process of the motorcycle anti-theft lock device 300 according to the present invention, when the driver touches the touch key 411 to the touch sensor 412, the touch sensor 412 senses the touching and transmits the on signal to the printed circuit board 420. Next, the printed circuit board 420 applies the power to the normal/reverse rotation motor 510 so as to drive the normal/reverse rotation motor 510.

[128] Next, the locking bar 520 having the rack gear 521 engaged with the pinion gear 512 which is coupled with the fixing shaft 511 of the normal/reverse rotation motor 510 is moved in the forward direction.

[129] Next, by the reverse rotation of the pinion gear 512, the locking bar 520 is moved in the forward direction through the supporting hole 312 of the housing 310 and the exit hole 321 of the case 320. The locking bar 520 is extracted from the insert hole 110 of the steering-handle rotating shaft 100 of the motorcycle, so that the lock device is unlocked.

[130] On the other hand, the process where the card key 413 is touched to the card key sensor 414 and the on/off signal is transmitted to the printed circuit board 420 so as to drive the power transmission means 500, the process where the password sensor 415 senses input of the password which is previously registered by the driver and the on/off signal is transmitted to the printed circuit board 420 so as to driver power transmission means 500, and the process where the remote controller 416 is manipulated and the on/ off signal is transmitted to the printed circuit board 420 so as to driver power transmission means 500 are described hereinbefore, and thus, detailed description thereof will be omitted.

[131] According to the motorcycle anti-theft lock device of the present invention, the printed circuit board that receives the on/off signal from the sensor unit 410 provided to the outer case 200 of the motorcycle controls connection and disconnection of the power to the power transmission means 500, so that the locking bar 520 is moved in the forward and backward directions to be locked and unlocked to the insert hole 110 of the steering-handle rotating shaft 100. Accordingly, it is possible to prevent theft of the motorcycle. While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the appended claims.
