Abstract
An antitheft device for use on bicycles. The device has three limbs (1,2,3) which are pivotally connected to each other. In, use the limbs (1,2,3) are lockable around part of a bicycle (8) and/or fixed structure in a triangular configuration. When not in use the limbs are unlocked and folded one within another to a rectilinear configuration for storage or carrying purposes. The device has the advantages of being compact in the folded position to facilitate storage on part of the bicycle frame.
Claims22
A bicycle antitheft device comprising at least three substantially rigid limbs and a security lock housed in one of said limbs, two of said limbs being pivotally attached to one other of said limbs, said limbs being lockable with said lock in a first position wherein said limbs cooperate to define a closed frame structure having an open interior area, wherein said device is securable to a bicycle so that a portion of said bicycle passes through said open interior area, said limbs being pivotable for movement to a second position in which all of said limbs, other than a first one of said limbs, are nested within the first limb and cooperate therewith to form a rectilinear structure which is securable in substantially parallel relation to a rectilinear portion of said bicycle.
A bicycle antitheft device comprising at least three substantially rigid limbs and a security lock on one of said limbs, two of said limbs being pivotally attached to another one of said limbs, said limbs being lockable with said lock in a first position wherein said limbs cooperate to define a closed frame structure having an open interior area, wherein said device is securable to a bicycle so that a portion of said bicycle passes through said open interior area, said limbs being pivotable for movement to a second position in which one of said limbs is nested within at least two other of said limbs and cooperates therewith to form a rectilinear structure which is securable in substantially parallel relation to a rectilinear portion of said bicycle.
A bicycle antitheft device comprising first, second and third substantially rigid limbs, said first and third limbs being pivotally attached to said second limb, said limbs being positionable in a first position wherein they cooperate to define a closed frame structure having an open interior area and a security lock for releasably locking said device in the first position, wherein said device is securable to a bicycle so that a portion to said bicycle passes through said open interior area, said limbs also being pivotable for movement to a second position in which said second limb is nested within the first and third limbs and cooperates therewith to form a rectilinear structure which is securable in substantially parallel relation to a rectilinear portion of said bicycle.
