BACKGROUND OF THE INVENTION:
Field of the Invention:
05 This invention is related to an automobile antitheft device, and more particularly to a device for attachment to an automobile steering wheel to prevent complete rotation thereof for securing against unauthorized driving.
Description of the Prior Art:
Antitheft devices which attach to an automobile steering wheel have been known heretofore, as shown in U.S. Patent No.4,738,127 to Johnson. Such an antitheft device for attachment to a steering wheel of an automobile includes an elongated body member having a passage extending along a longitudinal axis thereof, an elongated rod member adapted to move in telescopic fashion in the passage of the body member along the axis, opposed hooks for engaging inside portions of the steering wheel and lock means associated with the body member for engaging the rod member within the passage to lock the rod member within the passage in a stationary position with respect to the body member at any one of a plurality of positions. While the antitheft device described above is functional, it includes several defects. For example, both extension and retraction telescopie movements of the rod member need a key to unlock the lock means. Another problem with such device is that it presents pry points wherein a rigid pin or thin arcuate ruler-like objects can be inserted through a gap between the passage and periphery of the rod member to reach a spherical bearing of the lock means and further press it 05 down by overcoming the bias force of a spring member thereon to release it from engaging the rod member in a groove thereof and cause the device to unlock.
SUMMARY OF THE INVENTION:
It is accordingly a primary object of this invention to provide an automobile steering lock that overcomes the foregoing defects associated with prior art devices.
Another object of this invention is to provide an automobile steering lock that performs a non-return, extension only function in a locking condition.
A further object of this invention is to provide a lock device wherein the locking mechanism is totally enclosed therein and includes no area susceptible to prying by a crowbar, rigid pin or the like.

The locking member 35 includes an arcuate outer surface 36 and a flat or recess portion 37.
To accommodate the actuating means 18, an elongated compartment 38 disposed substantially parallel to the central 05 passage 31 is formed in the housing 15. The bore 33 of the boss 32 intersects the compartment 38. The actuating means 18 includes a rod-like actuating member 39 having a projection 40 projecting rearwardly from a rear side wall of the actuating member 39 and a biasing spring 41 adapted to be disposed within the compartment 38 with a front end thereof surrounding the projection 40 and abutting against the rear side wall of the actuating member 39. The actuating member 39 is formed with a recess 42 defined by a flat bottom and opposed stop side walls 43, 44 in its middle portion and two spaced notches 45, 46, each of which incldues a vertical side wall 47 or 48 relatively close to the projection 40 and a convex or sloping side wall 49, 50, respectively, positioned away from the projection 40. A
metal disc 51 is provided for a press fit engagement in an open end of the compartment 38 after assembly for retaining the actuating member 39 and spring 41 in the compartment 38.
To accommodate the locating means 17, a pair of passages 52, 53 are provided extending transversely across the compartment 38 and futher intersect the central passage 31 in the housing 15. The locating means 17 includes a pair of tenon-like identical locking members 54, 55, each of which has - 20201 8~

Spring retainers 66, 67, 68, and 69 are provided for retaining rear ends of the springs 60, 61, 62 and 63. The locating member 54, 55, springs 60, 61, 62, 63 and spring retainers 66, 67, 68 and 69 are maintained in the transverse passages 52, 53 by a retainers 70. The springs 60, 61, 62, 63 are confined within passages 52, 53 in compression such that the locating members 54, 55 are biased towards the central passage 31.
Referring to Figs. 3, 4 and 5, in assembly, the locating ~' members 54, 55 are slidably fitted in the transverse passages 52, 53, the actuating member 39, which extends through the openings 71, 72 of the locating members 54, 55 is slidably fitted in the compartment 38 wherein the recess 42 thereof 05 faces the bore 33 of the boss 32. The conventional key lock 34 of the locking means 16 is firmly received in the bore 33 of the boss 32 by means of which extends through a bore formed in a bottom portion of the boss 32 and interconnecting bore 33 and central passage 31 of housing 15, with screw 73 being tightly threaded into a screw holes 74 of locking means 16, as best shown in Figs. 2 and 5. The locking member 35 of lock 34 extends substantially downwardly into the recess 42 of the actuating member 39.
In operation, when the flat or recess portion 37 of the locking member 35 is oriented rearwardly, as shown in Figs. 3, 4 and 5, it allows the flat or recess portion 37 of member 35 to abut on the stop side wall 44 close to the projection 40 of the actuating member 39 and the spring 41 is in compression to bias and push the actuating member 39 forwardly into its first position where the locating members 54, 55 are biased towards rod member 12 into their first position such that the vertical rear side walls 64, 65 abut against bottom of the notches 45, 46, respectively, of the actuating member 39 and the front ends of the locating members 54, 55 protrude into 5 corresponding notches 28 to lock the device.
Although in locking condition, the convex or slope side walls 30 of the notches 28 allow the rod member 19 of this antitheft device to extend with respect to the body member 11 by overcoming biasing force of the springs 60, 61, 62, 63 to 05 retract the locating members 54, 55 from the first position into the second position, yet the vertical side walls 29 engaged with the front ends of the locating members 54, 55 prohibit the rod member 12 from telescopic retracting movement with respect to the body member 11. When the flat or recess portion 37 of the locking members 35 is turned away from the position towards and abutting the stop side wall 44, the arcuate outer surface 36 forces the actuating member 39 to slide rearwardly into a second position by overcoming biasing force of the spring 41. The locating members 54, 55 are retracted from the first position into the second position by overcoming biasing force of the springs 60, 61, 62, 63 and thus releasing the vertical rear side walls 64, 65 from corresponding spaced notches 45, 46 in the actuating member 39.
By so doing, the rod member 12 can move in telescopic fashion within the body member 11 by withdrawing the front end of the locating members 54, 55 from corresponding notches 28 of the rod member 12 into transverse passages 52, 53.
As shown in Figs. 1 and 2, the hook defined by the front end portion 26 and the L-shaped 25 both of which are formed respectively with front ends 75, 76 extending frontwardly ,'f, outwardly provides a divergent opening for facilitating entrance of the portion of the steering wheel. The hook defined by the rear end portion of the body member 11 and the L-shaped 19 which has a bent end 76 extending rearwardly and outwardly 05 also provide a divergent opening for the same purpose as the former hook.
While the invention has been described with respect to a preferred embodiment thereof, it is obvious that various modifications can be made therein without departing from the spirit of present invention which should be limited only by the scope of the claims.

Spring retainers 66, 67, 68, and 69 are provided for retaining rear ends of the springs 60, 61, 62 and 63. The locating member 54, 55, springs 60, 61, 62, 63 and spring retainers 66, 67, 68 and 69 are maintained in the transverse passages 52, 53 by a retainers 70. The springs 60, 61, 62, 63 are confined within passages 52, 53 in compression such that the locating members 54, 55 are biased towards the central passage 31.
Referring to Figs. 3, 4 and 5, in assembly, the locating ~' members 54, 55 are slidably fitted in the transverse passages 52, 53, the actuating member 39, which extends through the openings 71, 72 of the locating members 54, 55 is slidably fitted in the compartment 38 wherein the recess 42 thereof 05 faces the bore 33 of the boss 32.
