Abstract
Abstract A first elongated rod of hardened metal comprises a first link which spans both wheels of a bike and can also encompass, if desired, a sturdy post, or the like, against which the bike is leaned for support. A second link member comprises another rod which is shorter than the first and is articulated to one end of the first link. A third link member, preferably comprising two or more articulated link portions, is articulated to the other end of the first rod. The second and third link members are joined together at their free ends by lock means on the side of the bike opposite to that occupied by the first link. The three rods not only lock the wheels but also pass through the triangular frame member formed by the seat tube, the seat stays and the chain stays and thereby secure the wheels to the frame.

Claim 1
Independent Claim
257 words
A security device for a two wheel bike comprising: a. a first link member including a bar of hardened metal having a length sufficient to span the distance between the adjacent rim portions of both wheels of the bike, said first bar having at opposite ends a pair of loops, both of said loops extending in a direction away from said bar such as to protrude at least partially through the spokes of both wheels with said bar aligned so as to span the wheels; b. a second link member including at least one substantially linear bar of hardened metal, said second link member having at opposite ends a pair of rings, said first link member being linked with said second link member by engagement between one of said loops and one of said rings; c. a third link member including at least one substantially linear bar of hardened metal, said third link member having at opposite ends a pair of eyes, said first link member being linked with said third link member by engagement between the other of said loops and one of said eyes; and, d. lock means for releasably connecting said second link member to said third link member by interengagement between said lock means, another of said rings and another of said eyes, the combined lengths of said second link member and said third link member exceeding the distance between said loops by an amount sufficient to encompass the adjacent rim portions of both wheels and a securing post located adjacent the wheels.
