The present invention relates to a gear lever locking device.
To combat the problem of automobile theft, many different types of automobile anti-theft devices have been developed. Such anti-theft devices include electric anti-theft alarm device units or mechanical devices e.g., a steering wheel locking device or a brake pedal/clutch locking device. However, conventional mechanical anti-theft devices have various drawbacks, such as, the need to install such devices permanently to a steering wheel column thereby causing a potential blockage or hindrance to a user of the automobile controls when driving. Such issues can potentially contribute to unexpected accidents. Additionally, permanently attaching such mechanical devices to a steering wheel column gives an inferior appearance, as such devices are visible from outside the automobile.
Removable mechanical anti-theft devices are also problematic. For when such devices are unused, they must be keep in an area of the automobile that does not obstruct a driver's movement. As a result, such removable anti-theft devices are inconvenient to use.
Another conventional mechanical anti-theft device is a gear lever locking device having a loop retaining an automobile gear lever installed in a position preventing movement of the gear lever. However, such a loop retaining gear lever lock is problematic in that it is not aesthetically pleasing and can potentially be destroyed or disabled by an individual as the device is located or mounted on an existing gear lever outside the cover of the gear lever.
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.
In accordance with a preferred embodiment, the present invention provides a gear lever locking device having a first main axle pipe, a first sliding axle pipe, a spring, a sliding-pulling axle, an extending axle, an electric switch, and a second main axle pipe. The first main axle pipe includes an interior, a bottom, a side wall, and a bent first fixing leg member. The bent first fixing leg member extends from the bottom of the first main axle pipe for installation in a vehicle at an existing position of a screw of the vehicle.

It should be noted that the drawings are in simplified form and are not drawn to precise scale. In reference to the disclosure herein, for purposes of convenience and clarity only, directional terms such as top, bottom, above, below and diagonal, are used with respect to the accompanying drawings. Such directional terms used in conjunction with the following description of the drawings should not be construed to limit the scope of the invention in any manner not explicitly set forth.
In accordance with a first preferred embodiment, the present invention provides for a gear lever locking device 10, as shown in
A bent first fixing leg member 30 is connected to the bottom 12b of the first main axle pipe 12. The bent first fixing leg member 30 is configured as best shown in
The first sliding axle pipe 14 is generally configured as an elongated axle pipe, as shown in
The spring 16 can be any spring or biasing member generally known in the art, such as, a compression spring or a constant force spring. The spring 16 is sized and configured to be received within a front end 14b (
The sliding-pulling axle 18 is generally configured, as best shown in
The extending axle 20 is generally configured as a stud, as best shown in
The electric switch 22 is mounted to the first main axle pipe 12 (
The second main axle pipe 24 is generally configured as an elongated axle pipe, as best shown in
As best shown in
The second main axle 24 includes at least one bent second fixing leg member 52 (
The gear lever locking device 10 can include one and preferably two extending axles 20. The extending axles 20 can each be fixed or connected to a side wall of the first sliding axle pipe 14 such that each extending axle 20 extends through the respective openings i.e., 28, along the sidewalls of the first main axle pipe 12 (
In an assembled configuration, the retractable spring 16 is inserted within the front end 14b of the first sliding axle pipe 14 and pushes against an end cap 14c that is securely fixed to and closes off the front end 14b. An opposite end of the retractable spring 16 pushes against a transverse stud 54, as best shown in
The gear lever locking device 10 further includes a turning mechanism 56 to lock and unlock the gear lever locking device 10 from the locked configuration, as best shown in
The spring 60 is located within the casing 56c and positioned between the locking stud 62 and an internal wall surface of the turning mechanism's casing 56c, such that the spring 60 can bias the locking stud 62 to a locking position in which the locking stud 62 extends through through-holes 26 and 34. The turning mechanism 56 is configured such that upon the turning lock 56a being turned, the offset part 56b pushes or cams against the locking stud 62 to move it from the locking position to the unlocking position, thereby allowing the first sliding axle pipe 14 to slide relative to the first main axle pipe 12. The force for sliding the first sliding axle pipe 14 being provided by the force of the compressed retractable spring 16.
The first sliding axle pipe 14 is movable between a first position and a second position. The second position corresponds to a location of the extending axle 20 being located exactly above the screw 30d of the first fixing member 30 (
The sliding-pulling axle 18 is connected to the gear lever locking device 10 about a rear end 12f of the first main axle pipe 12, such that the sliding-pulling axle 18 is slidable within the through slot 36. The turning mechanism 56 is assembled slightly forward of the sliding-pulling axle 18 such that the locking stud 62 extends through through-holes 26 and 34, respectively. The second main axle pipe 24 is connected to the first main axle pipe 12 and the sliding axle pipe 14 via first and second connecting members 38, 40, respectively (
The transverse rod 44 is generally configured as shown in
The operation of the gear lever locking device 10 with respect to the first sliding axle pipe 14 is best shown in
In operation, the gear lever locking device 10 is used to securely locked the gear lever 5 or gear stick of a vehicle in position until the gear lever locking device 10 is unlocked or moved from the closed configuration to the open configuration. To move the gear lever locking device 10 to the open configuration, a user must first unlock the turning mechanism 56 such that the locking stud 62 is moved from the locking position to the unlocking position. This can be accomplished, for example, by a key 56d that is inserted into the turning unit 56a, as shown in
The gear lever transverse mechanism 114 includes a first sliding axle 116 having a front end 116a. The front end 116a extends transversely to a longitudinal axis of the sliding axle 116 and projects through the side opening 112a on the wall of the axle pipe 112. The front end 116a is bent to form a curved front transverse rod 116b for retaining or blocking movement of the gear lever (not shown). A rear end 116c of the sliding axle 116 is connected to a side of a second sliding axle 118 (
The second sliding axle 118 is configured, as shown in
The gear lever transverse mechanism 114 also includes a rear transverse rod 122 positioned rearwardly of the front transverse rod 116b. The rear transverse rod 122 is bent to form a curved rear transverse rod 122 for retaining or blocking the movement of the gear lever and is preferably symmetric to the front transverse rod 116b. The rear transverse rod 122 is pivotably connected to axle pipe 112 by a stud 124 and projects though the opening 112a of the axle pipe 112. The rear transverse rod 122 is also fixed to the sliding axle 116 by a stud 126. Thus, as the sliding axle 116 slides forwardly and rearwardly, the rear transverse rod 122 pivots between an open configuration and a closed configuration.
The gear lever locking device 110 also includes a stand 128 and screw guard member 130. The stand 128 is connected to a bottom part of the axle pipe 112 and/or a second axle pipe 132 for fixing the gear lever locking device 110 to a vehicle's console about an existing screw position (not shown). The second axle pipe 132 is configured as shown in
The screw guard member 130 is configured, as shown in
The turning mechanism 120 includes a turning lock unit (not shown), an axle 120a, a casing 120b and a cam 131. The cam 131 is connected to the rotating axle 120a and pivots about a central axis. The turning mechanism 120 is installed about a side wall of the second axle pipe 132, preferably about a rear end of the second axle pipe 132, as shown in
The cam 131 includes a pivot 131a extending from an offset point of the cam 131. The pivot 131a engages with a notch groove 118c on the rear end of the second sliding axle 118.
In operation, the turning mechanism 120 is turned to move the gear lever transverse mechanism between the open and closed configurations. That is, turning the turning mechanism 120 causes the pivot 131a, which is engaged with the notch groove 118c, to pivot thereby sliding the second sliding axle 118. The second sliding axle 118, being connected to the sliding axle 116, causes the sliding axle 116 to correspondingly slide. As a result, the sliding movement of the sliding axle 116, being connected to the rear transverse rod 122, causes the rear transverse rod 122 to pivot about the stud 124 between the open and closed configurations.
The second sliding axle 218 is configured as best shown in
The turning mechanism 220 of the third preferred embodiment is similar to the turning mechanism 120 of the above second preferred embodiment, except that the turning mechanism 220 includes a driving gear 231 rather than the cam 131. The driving gear 231 is connected to the axle 220a and rotatable as the turning mechanism 220 is rotated. When assembled with the second axle pipe 232, as shown in
The key lock cylinder 324 is installed in and connected to a case 326 that houses the springs 330, plate 328 and cam 334. The case 326 has an opening 326a for receiving the key 322 and a plate 326b for closing the opening 326a. This assembly is connected to the side wall of the sliding axle pipe 344 by fixing devices 332, such as screws (see also
The cam 334 is configured as best shown in
The plate 328 includes a slot 340 configured to receive the axle 334a and convex studs 336 of the cam 334. The plate 328 also includes a stud 338 extending downwardly from an underside of the plate 328. The plate 328 is assembled onto the axle 334a of the cam 334 with springs 340 interposed between an upper surface of the plate 328 and the case 326, as best shown in
The plate 328 can be biased off of the cam 334 by turning the cam 334 via the key lock cylinder 324 and key 322, such that the convex studs 336 and the plate 328 upwardly relative to the cam 334. As a result, the convex studs 336 are rotated out of position relative to the slot 340 of the plate 328. This action of camming the plate 328 off of the cam 334 thereby raises the plate's stud 338 out of engagement with the sliding axle 344 so as to unlock the sliding axle 344. To thereafter lock the sliding axle 344, the turning mechanism 320 is rotated in the opposite direction to align the convex studs 336 with the slot 340, thereby producing a coupling between the support plate 328 and the cam 334. Then, due to the force of the springs 330, the stud 338 is pushed back into engagement with the hole 342a of the sliding axle 342.
The turning mechanism 412 provides the means for driving or moving the gear lever locking device 410 between a closed configuration and an open configuration i.e., a driving mechanism unit. That is, the turning mechanism 412 is turnable with a key (not shown) for driving the sliding axle unit 414, similar to the second preferred embodiment. The turning mechanism 412 includes a turning axle 422, a cam 424, an axle stud 426, and a turning mechanism chamber 428 and is configured as generally described for the turning mechanism 120 of the second preferred embodiment. The turning mechanism chamber 428 is connected to a mechanism chamber 430 which in turn is connected to a rear end of the sliding axle chamber 416. The turning mechanism 412 is configured to have the stud 426 engage with a stud groove 432 about the rear end of the sliding axle unit 414.
The sliding axle unit 414 includes a first end 414a and a second end 414b. The stud groove 432 is configured about the first end 414a and a member end 434 is configured about the second end 414b. The member end 434 connects to the gear lever transverse mechanism 420. The sliding axle unit 414 also includes an elongated cylindrical rod 414c that connects the first and second ends 414a, 414b and a member 436 rigidly mounted on the cylindrical rod 414c and secured in place by a screw 414d. The member 436 is mounted onto the cylindrical rod 414c so as to be correspondingly positioned with the opening 416a of the sliding axle chamber 416 when assembled thereto. The member 436 includes a recess 436a for receiving an axle 438 that extends out from a side wall of the sliding axle chamber 416, as further discussed below.
The sliding axle chamber 416 is configured, as best shown in
The gear lever transverse mechanism 420 is connected to a front end of the sliding axle chamber 416 and configured as best shown in
The gear lever transverse member 448 includes a sliding groove 452 configured about a upper surface of the gear lever transverse member 448 facing the plate member 444. The gear lever transverse member 448 is configured to extend through the opening 442a of the mechanism unit chamber 442 transversely with respect to the sliding axle chamber 416. The sliding groove 452 receives the transverse stud 446, such that the gear lever transverse member 448 can slide relative to the transverse stud 446. That is, as the plate member 444 is moved via the turning mechanism 412, the plate member 444 causes the gear lever transverse member 448 to extend further out to a locked configuration, as shown in
The cover 450 is a plate cover that secures the plate member 444, transverse stud 446 and gear lever transverse member 448 into the mechanism unit chamber 442. The cover 450 is attached to the mechanism unit chamber 442 by screws.
The fixture 418 includes a first stand unit 454, a second stand unit 456 and a screw guard 440. The first and second stand units 454, 456 are configured as shown in
In operation, the turning mechanism 412 operates similar to the turning mechanism 120 of the second preferred embodiment, to move the gear lever transverse mechanism 448 between the locked and unlocked configurations. That is, turning the turning mechanism 412 causes the axle stud 426, which is engaged with the stud groove 432, to pivot thereby sliding the sliding axle unit 414 within the sliding axle chamber 416. The member 434 of the sliding axle unit 414 is connected to the plate member 444 such that the plate member 444 slides correspondingly with the sliding axle unit 414. As a result, the sliding movement of the plate member 444 causes the transverse stud 446 of the plate member 444 to travel within the sliding groove 452, which in turn causes the gear lever transverse member 448 to either retract (unlocked configuration) or extend (locked configuration) from the mechanism unit chamber.
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.
