[0001] GEAR LEVER LOCKING DEVICE

BACKGROUND OF THE INVENTION

[0002] The present invention relates generally to a gear lever locking mechanism for a vehicle. In particular, the present invention relates to a gear lever locking mechanism mountable directly onto a gear lever housing frame of a vehicle to lock movement of the vehicle's gear lever.

[0003] Conventional gear lever locking devices include a mechanism for locking a typical gear lever of an automobile. The typical gear lever locking device is a loop member for use in locking the gear lever only in one particular position according to the installation position. In addition, the aforementioned gear lever locking device's loop member may be unlocked by an unlocking key system. However, conventional gear lever locking devices have an operational drawback. That is, if a user wants to shift the locking position of the gear lever from the parking position (P position) to the neutral position (N position), it is impossible to shift the gear lever to the position that meets the operational requirements. Moreover, the commonly used or commercially available locking device is installed outside the gear lever cover panel, thereby deteriorating the outer appearance of the gear lever locking device installed in the vehicle, or exposing the device to become more easily damaged, and or inhibiting sufficient convenience during its usage.

[0004] Moreover, gear lever locking devices are typically required to be permanently installed alongside the gear lever. Sometimes, the installation in this manner can make the user feel that these members obstruct the steering of the automobile and possibly lead to an unexpected accident. If the device is a detachable type after being unlocked, then the detached member has to be placed in a proper place so that it will not interfere with the driver, which is inconvenient. In addition, sometimes the installation of the gear lever locking device requires some modifications to the components that have originally been installed in the automobile or other vehicle.

[0005] Thus, there is still a need for an automobile gear lever locking device capable of locking a gear lever that addresses the aforementioned problems of conventional mechanical anti-theft devices. Such a need is satisfied by the automobile gear lever locking device of the present invention.

[0086] The locking stud 76 engages the first stud 82 of the locking mechanism 16 arranged inside the locking mechanism housing 72. The first stud 82 is actuated to push the locking stud 76 to be locked to the groove 52 or the hole 50 on the connector 14 into the locked configuration. Either the groove 52 or the hole 50 is used depending upon the position of the gear lever itself, e.g., the gear levering being in a forwardly position (first gear) or a rearwardly position (second gear). The locking stud 76 slides out of the groove 52 or the hole 50 on the connector 14 while unlocking the first stud 82 inside the locking mechanism housing 72 to which the return spring 78 is mounted. The spring 78 pushes the body of the locking mechanism 16 out of its locked position. The outer end of the locking mechanism housing 72 is mounted to the locking mechanism 16 having the first stud 82 arranged inside the first stud sheath 84. The stud sheath 84 is actuated by the locking mechanism 16. The first stud 82 is locked to the locking mechanism housing 72 to prevent the retreating movement of the locking stud 76. Moreover, the locking mechanism 16 can include a key 86 used for locking and unlocking.

At least one screw is positioned in the lower part and in the correspondent position with the axle 422 when the gear lever locking device 400 is in the locked position.

[0134] Referring to Fig. 25, another embodiment of the gear lever locking device according to the present invention is shown comprising a sustaining axle 466. The sustaining axle 466 is a bent member one end of which engaged with the end of the sliding axle 404. The other end is engaged with the sustaining axle pipe 470 fixed to the sliding axle chamber 402 in the position that the end of the sustaining axle 466 can move to obscure the screw fastening the screw guard 460. In addition, there is also an intermediate pipe 472 to prevent the striking between the sustaining axle 466 and the inner part of the sustaining axle pipe 402. This avoids undesired noise from the gear lever locking device 400. At the portion between the seats 410, 412, there is a diaphragm 464 cut into a downwardly protruding shape suitable for closing a lower gap between the sliding axle 404 and the body of the vehicle.

[0135] Referring to Figs. 28-32, the above-described embodiments of the gear lever locking device further includes an alarm system 500 and an anti-start system 517. The alarm system 500 and anti-start system 517 are anti-theft/security systems to prevent the vehicle from theft. The alarm system 500 is an electrically supplied system that includes a micro switch set 507, an electronic security system 508, and an audible alarm device 510. The micro switch set 507 is attached via the through hole on the lateral side of the turning mechanism 74 (Fig. 30). The alarm system 500 applicable to the present invention, will now be described with reference to the gear lever locking device 10 described above, however, the alarm system 500 is compatible with any of the above-described embodiments of the gear lever locking device.

[0136] The gear lever locking device 10 has a turning mechanism 74 that is turned by the key 86. The turning mechanism 74 is further configured to include the micro switch set 507 having a key code member 502 with a protrusion 504 for use in extending through a through hole to a micro switch 506 (Fig. 30) installed on the body of the locking mechanism 16 when the key 86 is inserted into the locking mechanism 16 for turning and unlocking the gear lever locking device 10. The micro switch 506 is the mechanism used in supplying an electric current to activate the electronic security system 508 of the alarm system 500 to emit a code signal wave to determine a corresponding code signal wave of the key 86 having a signal code storage device attached thereto or embedded therein. If the code signal from the key 86 matches the code signal from the electronic security system 508 installed inside the vehicle, the alarm system 500 will not be triggered to sound the audible alarm device 510. However, if the locking mechanism 16 is unlocked by another different device or if the key 86 does not include the correct code signal that matches the code signal from the electronic security system 508 provided inside the vehicle, the electronic security system 508 will turn on the alarm system 500 and sound the audible alarm to alert the unusual situation.

[0137] That is, the aforementioned key code member 502 includes the protrusion 504 to be coupled to a rod 516 used in pressing the micro switch 506 coupled to a return spring 512 (see Fig. 30). The rod 516 extends to the micro switch 506 having a signal wire 514 connected to the electronic security system 508 and a lower portion 502a of the key code member 502 is inclined corresponding with an insertion direction of the key 86. The length of the rod 516 matches the timely distance where the micro switch 506 can operate.

[0138] The anti-start system 517 applicable to the present invention, will now be described with reference to the gear lever locking device 10 described above, however, the anti-start system 517 is compatible with any of the above-described embodiments of the gear lever locking device.

[0139] The anti-start system 517 serves as an additional or optional anti -theft/security system to protect the vehicle from theft. The anti-start system 517 includes a set of electric wires 518 called a "wire socket". At one end, the wire socket 518 is connected a micro switch 530. At the other end, the wire socket 518 is connected an electric system of the vehicle for supplying electricity, preferably at a position under the steering wheel system of the vehicle. The micro switch 530 is attached on the lateral side of the upper portion 30a of the cover member's cover element 30, as shown in Figs. 5, 6 and 29. The micro switch 530 includes a switch pressing rod 531 (Fig. 5) attached thereto and protruding through the opening on the lateral side of the cover element 30.

[0140] When the gear lever locking device 10 is in the locked position, the first stud 82 (Fig. 1A) will be slid to push against the switch pressing rod 531. The switch pressing rod 531 will slide to push a trigger 530a (Fig. 5) on the micro switch 530. Once the micro switch's trigger is pressed, the electricity supplied to the micro switch 530 will be cut off since an electrical circuit is not completed, thus preventing the vehicle's engine from being started. [0141] The first stud 82 is slid out of the locked position and away from the trigger of the micro switch 530 when the gear lever locking device 10 is moved to an unlocked position, thereby completing the electrical circuit of the micro switch 530. Electricity is then supplied to the anti-start system 517, thereby allowing the engine to start and the regular movement of the gear lever.

[0142] Fig. 32 shows a flow diagram illustrating the operational configuration of the alarm system 500 and the anti-start system 517. When the gear lever locking device is in a locked state, the switch pressing rod 531 will push the trigger 530a on the micro switch 530 of the anti-start system 517. The supplied electricity to the micro switch 530 will then be cut off since the electrical circuit is not complete. The vehicle's engine cannot then be started. In addition, when the turning mechanism 74 is inserted with the key 86 (Fig. 31) or invaded by some foreign object, the electronic security system 508 will be activated by the micro switch 506 and will transmit the signal wave to determine the code signal stored on a part of the key 86. If the code signal matches the preset one, the alarm system will not be activated. On the other hand, if the code signal does not match the preset one, the alarm system 500 will be triggered and remain active by the electronic security system 508. The aforementioned electronic security system 508 is able to then terminate the alarm system 500 by inserting the key 86 with the correct preset code or pressing the reset button on the electronic security system to reset the security system to the original condition. [0143] Another embodiment of the alarm system can be described as follows. The turning mechanism 74 along with one key code set includes a through hole. The two ends of the through hole are provided with an infrared switch on opposite sides. The infrared switch activates the electronic security system 508 to emit the code signal wave to determine the code signal wave of the key 86 having the signal code storage device attached thereto. If the code signal from the key 86 matches the code signal from the electronic security system 508 installed inside the vehicle, the sound alarm system will not be activated. If it is unlocked by another different device or if the key does not have a code signal that matches the code signal from the security system provided inside the vehicle, the security system will turn on the alarm system to alert the unusual situation. [0144] Each of the components of the above described gear lever locking device embodiments can be made from metal, such as steel or iron, or any other strong material suitable for its intended use, such as a ceramic or composite material. Such materials are known in the art and a detailed description of such suitable materials is not necessary for a complete understanding of the present invention.

[0145] It will be appreciated by those skilled in the art that changes could be made to the embodiments described above without departing from the broad inventive concept thereof. For example, additional components and steps can be added to the various gear lever locking devices. It is to be understood, therefore, that this invention is not limited to the particular embodiment disclosed, but it is intended to cover modifications within the spirit and scope of the present invention as defined by the appended claims.
