An antitheft device for attachment between two points defining a chord on the rim of an automobile steering wheel comprising:
- a tubular member, said tubular member having an inner open end adapted to be positioned within said rim, first hook means on said tubular member for securing said device to one of said points on said steering wheel;
- a rod member telescopingly received within said tubular member, said rod member having regularly spaced grooves extending from one end thereof over a longitudinal portion of said rod member, second hook means on said rod member for securing said device to the other one of said points on said steering wheel;
- one of said members having a predetermined length so that when said first and second hook means secure said device to said rim said member's length prevents continued rotation of said steering wheel;
- a lock on said tubular member;
- means for securing said lock to said inner end of said tubular member including locating means permitting telescopic movement of said rod member in a yieldably ratcheting manner and locking means rotatable from an unlocking position permitting telescopic movement of said rod member within said tubular member to a locking position preventing relative movement between said rod member and said tubular member;
- said locating means including said tubular member having a circular opening formed in said inner end thereof, said lock having a closed passageway aligned with and opening to said circular opening when said lock is assembled to said tubular member, a spherical bearing contained within said passageway, said bearing having a diameter slightly greater than said circular opening and biased into said circular opening to partially intersect said passageway and contact said grooves in said rod member to connect said lock to said tubular member while restraining lateral movement of said rod member within said tubular member;
- and
- said locking means including said tubular member having a slot formed therein diametrically opposite said circular opening, a generally cylindrical locking member rotatably mounted within said lock and aligned with said slot in said tubular member, said locking member having a flat portion on one side thereof and an arcuate portion opposite thereto and rotatable from said unlocking position whereat said flat portion is approximately flush with said slot to a locking position whereat said accurate portion extends through said slot to contact one of said annular grooves of said rod member thus locking said rod member to said tubular member in said locking position while connecting said lock to said tubular member in both said locking and unlocking positions.
