DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0093] Certain terminology is used in the following description for convenience only and is not limiting. The words “right,” “left,” “top,” and “bottom” designate directions in the drawings to which reference is made. The words “inwardly” and “outwardly” refer to directions toward and away from, respectively, the geometric center of the anti-theft device and designated parts thereof. The terminology includes the words above specifically mentioned, derivatives thereof, and words of similar import. Additionally, the words “a” and “one” are defined as including one or more of the referenced item unless specifically stated otherwise. Furthermore, the words “generally radially outwardly from the steering column,” as used in the claims and in corresponding portions of the specification, are defined as including elongated members that are tangent to the steering column or generally tangent to the steering column except for a small space between the steering column and elongated member.

[0094] Referring to FIGS. 1-81, wherein like numerals indicate like elements throughout, there are shown preferred embodiments of an anti-theft device according to the present invention. Briefly stated, the anti-theft device is attached to a vehicle 10 to limit the motion of a steering wheel 12 to deter theft of the vehicle 10.

[0095] It is preferred that the anti-theft device, and its individual components, be formed of a high strength, durable, impact resistant material, such as stainless steel. Those or ordinary skill in the art would appreciate that any other suitable steels, alloys or the like that are suitable for use with anti-theft devices can be used without departing from of the present invention. Preferably, an outer surface of the anti-theft device is coated with a brightly colored paint or coating, such as a fluorescent orange colored paint or vinyl coating, so that the anti-theft device is prominently visible and noticeable when installed on the vehicle 10.

[0096] Referring to FIGS. 1-7, one embodiment of the anti-theft device for vehicle is adapted to detachably engage the steering wheel 12 which is rotatable mounted on a steering column 14. The steering wheel 12 has a rim 16 defining an outer perimeter of the steering wheel 12. The rim of the steering wheel can be irregularly shaped without departing from the scope of the present invention.

[0097] The vehicle anti-theft device includes an elongated member 18 having a first end 20 and a longitudinal surface 22. The elongated member 18 is adapted to be located proximate to the steering column 14. Referring briefly to FIGS. 31 and 61-63 the elongated member can have a cross sectional shape of any one of a square, a rectangle, a circle, an ellipse, a polygon or the like without departing from the present invention. Additionally, the elongated member 18 can be an elongated ring (as shown in FIGS. 61-63) without departing from the scope of the present invention. Referring still to FIGS. 1-7, the first end 20 of the elongated member 18 preferably extends generally radially outwardly away from the steering column 14 past the outer perimeter of the steering wheel 12. It is preferable that the elongated member be adapted to be located on a portion of the steering column with the elongated member being generally, but not necessarily, perpendicular to a central axis of this steering column 14. When installed the elongated member 18 can be positioned at the joint between the steering wheel 12 and the steering column 14 (as shown in FIG. 3) to substantially surround the end of the steering column 14. Alternatively, the elongated member 18 can be positioned over a central portion of the steering column (as shown in FIG. 4) without departing from the present invention.

[0098] Referring to FIG. 77, the elongated member 18 may have a second end 24 extending past the outer perimeter of the steering wheel 12 without departing from the scope of the present invention. When such an anti-theft device is in the installed configuration, rotating the steering wheel in either direction (if possible depending on the engagement between the column engaging member 46 and the steering column 14) causes the elongated member to likely contact the right portion of the front windshield or the left door of the vehicle.

[0099] At least one wheel engaging member 26 is preferably disposed on the elongated member 18 and is adapted to engage the steering wheel 12 to prevent rotation of the steering wheel relative to the elongated member 18. The wheel engaging member 26 preferably includes a generally L-shaped plate 28 having one leg 30 that is adapted to overlay a front side portion of the steering wheel 12. Referring to FIG. 2, it is preferable, but not necessary, that the one leg 30 be adapted to overlay an air bag disposed in the steering wheel 12. As is known to those of ordinary skills in the art, the air bag 32 can be powered by a gas canister 34.

Referring to FIG. 15, the anti-theft device can be positioned on the right side of the steering column 14 with the elongated member 18 extending generally downwardly past the bottom of the steering column. Additionally, the anti-theft device shown in FIGS. 13- 15 can be positioned on top of the steering column in a position similar to that as shown in FIG. 1. This tremendous versatility of installation allows the anti-theft device to be optimally positioned depending on the characteristics of the vehicle 10 in which it is installed.

[0101] It should also be noted that the L-shaped beams 38 shown in FIG. 13-15 are positioned close enough to overlay a portion of the hub 42 of the steering wheel 12 and any air bag contained therein. Referring to FIGS. 16-19, the L-shaped beams 38 can be spaced so as to engage multiple spokes 44 of the steering wheel 12. As such, the front side portion of the steering wheel 12 being engaged by the L-shaped beams 38 can be any spoke(s) 44 of the steering wheel 12 without departing from the scope of the present invention. Referring again to FIGS. 13-15, the front side portion of the steering wheel that is overlaid by the L-shaped beams 38 can also be the hub 42 of the steering wheel.

[0102] Referring again to FIGS. 1-7 at least one column engaging member 46 has a generally transverse part 48 and at least one connecting part 50. It is preferable, but not necessary, that the connecting part 50 have ratchets thereon to allow a locking mechanism 54 to detachably secure the column engaging member 46 to the elongated member 18.

[0103] As best shown in FIG. 5, the connecting part 50 that is secured by the locking mechanism 54 preferably has ratchets 52 located thereon. The ratchets include downwardly beveled surfaces 52′ and flat bottom surfaces 54′ while the locking mechanism 54 preferably includes a sliding lock mechanism 56′ that engages the ratchets 52 to prevent the column engaging member 46 from being pulled downwardly out of the tube 56. The sliding lock mechanism 56′ is biased by a biasing member 58′, such as a spring, into the locked position, (shown in solid lines for component 56′ in FIG. 6). When a key or other activation mechanism is used to activate the locking mechanism 54, the sliding block mechanism 56′ is moved rightwardly into an unlocked position (shown by phantom lines for component 56′ in FIG. 6) which disengages a lip 60 of the sliding lock mechanism 56′from the ratchets 52 to allow the column engaging member 46 to be downwardly removed from the tube 56. While one preferred embodiment of a locking mechanism have been shown in the drawings, those of ordinary skill in the art will appreciate from this disclosure that any known locking mechanism can be used to secure the column engaging member 46 to the elongated member 18 without departing from the scope of the present invention.

[0104] As best shown in FIG. 2, it is preferable that tubes 56 are positioned through the elongated member to receive the connecting part(s) 50 of the column engaging member 46 therethrough.

Those of ordinary skill in the art will appreciate from this disclosure that the ring 68 can be generally rectangularly shaped or irregularly shaped without departing from the scope of the present invention. Referring to FIGS. 61-63, as mentioned above, the elongated member 18 can be a ring that is adapted to be positioned over another portion of the steering wheel 12.

[0110] Referring to FIGS. 24-29, 43-45, 52-56, the anti-theft device can use at least one spoke engaging member 70 (referring to FIGS. 24-27, the spoke engaging member 70 can be combined with a column engaging member 46 without departing from the scope of the present invention) instead of using a column engaging member 46.

[0111] The spoke engaging member 70 is preferably detachably engageable with the at least one wheel engaging member 26 and the at least one spoke 44 in an installed position in which the wheel engaging member 26 is engaged with the steering wheel 12. Referring to FIGS. 28 and 29, alternatively, the spoke engaging member 70 can be detachably engaged directly to the elongated member 18 without departing from the scope of the present invention.

[0112] Referring to FIGS. 52-55, it is preferred, but not necessary, that the spoke engaging member 70 include a connecting part 50 adapted to detachably engage the at least one wheel engaging member 26. The spoke engaging member 70 preferably includes two projections 72 disposed on the connecting part 50 that are adapted to extend along opposing lateral sides of the wheel spoke 44. Referring to FIGS. 20-23, the spoke engaging member 70 can be formed by two reverse hooks 74 that each extend beneath a separate spoke 44 to prevent rotation of the steering wheel 12 when the anti-theft device is in the installed position. Referring again to FIGS. 39-42, the spoke engaging member 70 may include a sheath 64 adapted to engage a portion of the rim when the anti-theft device is in the installed configuration. Referring to FIGS. 43-45, the spoke engaging member 70 can include two L-shaped beams 38 that can be positioned under separate spokes 44 to prevent movement of the steering wheel relative to the elongated member 18.

[0113] Referring again to FIGS. 52-55, the spoke engaging member 70 may, but does not necessarily, include a generally U-shaped bar 76 having a bent portion 78 to allow the spoke engaging member 70 to be inserted over the at least one spoke 44 and to be secured to the wheel engaging member 26.

[0114] Referring to FIGS. 66-69, the anti-theft device may include an elongated member 18 which includes a first part 80 in sliding engagement with a second part 82 and has a first end 20. The first part 80 slides along a central rod 84 that forms a portion of the second part 82. The first part 80 is locked in position on the central rod 84 via a locking mechanism 54.

[0115] A first jaw 86 is preferably disposed on the first part 80 of the elongated member 18 and is adapted to abut a portion of the steering column 14 when placed thereover. A second jaw 88 is disposed on the second part 82 of the elongated member 18 and is adapted to abut a portion of the steering column 14 and to, in combination with the first jaw 86, clamp the steering column 14 therebetween in an installed configuration in which the wheel engaging member 26 is engaged with the steering wheel 12 (as shown in FIGS. 67 and 69). It is preferable, but not necessary, that the first and second jaws 86, 88 are crescent-shaped and in opposing orientation. However, the contour of the steering column contacting surface of the first and second jaws 86, 88 can be customized depending upon the specifications of the vehicle 10 to be used with the anti-theft device. The use of first and second jaws 86, 88 allows the anti-theft device to be easily adjusted for steering columns 14 of non-typical dimensions.

[0116] Referring to FIGS. 70-72 first and second jaws 86, 88 can be used in conjunction with an elongated rod not having first and second parts 80, 82. To do so, the first jaw 86 is attached to a central rod 84 that is sidable within a slot 90. The central rod 84 can be secured in position via a locking mechanism 54 when the first and second jaws 86, 88 are appropriately spaced.

[0117] Referring to FIGS. 73-76, the elongated member 18 can be formed having an outer member 92 that is slidable relative to an inner member 94. The outer member 92 preferably has a longitudinal surface 22 and the inner member has a first end 20. The inner member 94 is preferably extendable generally radially outwardly away from the steering column 14 past the outer perimeter of the steering wheel 12. Referring to FIGS. 73 and 75, the right end of the outer member 92 has an inwardly directed flange 96 that engages a shoulder 98 of the inner member 94 when the inner member 94 is filly extended from the outer member 92.
