초록 ▼

Theft of a bicycle is discouraged by a locking mechanism in the front headstem that controllably engages the handlebar-attached headstem with the front fork or disengages the headstem and fork for free relative rotation. A shaft attached to the fork and a sleeve attached to the handlebar clamp are connected at a locking junction which is rotatable as a whole in the front journal of the frame. A key operated cam moves a locking roller radially outwardly of the shaft to engage a receptacle in the sleeve for engagement or allows the roller to retract into an aperture for disengagement. The shaft and sleeve have complementary conical tapers axially positioned by a split conical bushing. A cylinder lock operates the cam via a key having a substantially tubular configuration with a uniquely configured axial end for positioning lock pins against axial spring pressure. The key has a radially protruding guide tab, and fits into an annular key receptacle with two longitudinal slots, one for the guide tab upon insertion of the key, and the other capturing the key via the guide tab in the locking position of the lock. The key has a rounded end cap configured to cover a top of the frame headstock.

대표청구항 ▼

A mechanism for discouraging theft of a bicycle having a wheel on a fork rotatable about an axis relative to a frame headstock for steering the bicycle, and a handlebar mount for manually positioning the fork, the mechanism comprising: a first member having means for rigid attachment relative to the fork; a second member having means for rigid attachment relative to the handlebar mount, the first and second members being rotatably coupleable and decoupleable at a locking junction, one of the first and second members having at least one aperture carrying a locking body and the other of the first and second members having a receptacle for receiving the locking body, the receptacle having a radially sloping edge contour, the aperture and the receptacle being correspondingly positioned and dimensioned such that the locking body resides within said aperture when the aperture and the receptacle are misaligned, and the locking body can be displaced partway into the receptacle to reside partly in the aperture and partly in the receptacle when the aperture and the receptacle are aligned; a lock disposed at the locking junction of the first and second members, the lock having a cam movable between a first position wherein the cam urges the locking body from the aperture toward the receptacle, for fixing the first and second members against relative rotation, such that the bicycle can be operated, and a second position wherein the locking body is free to become retracted into the aperture by action of the sloping edge contour of the receptacle, such that the bicycle cannot be operated; wherein the first and second members define a concentrically arranged tube and cylinder, the tube and the cylinder having complementary conical tapers for securing the first and second members in an axial direction; and, means for fixing the first and second members at predetermined relative positions wherein the complementary conical tapers are urged together such that the first and second members are secured against relative axial displacement at a predetermined axial pressure.
