Abstract
The invention provides a bicycle lock with three rigid lock rods, either separable or articulating, which together provide an adaptable secure frame-to-wheel-to-security-object bicycle locking mechanism in conjunction with a removable seat post. One rod is inserted partially into the removed seat post, and the other rods extend outward from the first rod and then back toward the seat post for locking to a seat post clamp thereon, thus forming a closed triangular lock. The lock can be passed through the bicycle frame and wheel and around a bike rack or other external structure before closing to secure both the frame, wheel and seat post to the structure to prevent theft of any one or more of these components.
Claims18
In combination, a bicycle seat post and a seat post bicycle lock cooperable therewith, the seat post bicycle lock comprising:
- a series of rods including a pair of lock rods and an insertion rod that is arranged for insertion into the seat post through a free end thereof in a position leaving an exposed end of said insertion rod outside the seat post, the series of rods being arranged to be secured together end-to-end at relative angles to one another outside the seat post to lie on respective sides of a polygonal area with the insertion rod at one end of the series and a one of the lock rods at a second end of the series;
- a clamp arranged to clamp around the seat post at a distance from the free end thereof;
- and
- a lock mechanism attached to the clamp and arranged to lock the one of the lock rods to the clamp;
- wherein the series rods are connected by pivotal joints therebetween by which the lock rods and the insertion rod are foldable into a storage condition in which the lock rods and the insertion rod lie parallel to one another with longitudinal axes of the lock rods and the insertion rod occupying a triangular configuration lying on vertices of a triangle in a cross-sectional plane perpendicular to said longitudinal axes.
In combination, a bicycle seat post and a seat post bicycle lock cooperable therewith, the seat post bicycle lock comprising:
- a series of rods including a plurality of lock rods and an insertion rod that is arranged for insertion into the seat post through a free end thereof in a position leaving an exposed end of said insertion rod outside the seat post, the rods being arranged to be secured together end-to-end at relative angles to one another outside the seat post to lie on respective sides of a polygonal area with the insertion rod at one end of the series and a final one of the lock rods at a second end of the series;
- a clamp arranged to clamp around the seat post at a distance from the free end thereof;
- and
- a lock mechanism attached to the clamp, arranged to lock the final one of the lock rods to the clamp, and operable to both close the clamp around the seat post and lock the final one of the lock rods to the clamp;
- wherein the lock mechanism comprises a cover member pivotally coupled to the clamp for movement into and out of a lockable position in which the cover member conceals a closure of the clamp and captures an end of the final one of the lock rods.
