The device of the present invention is a locking quick release device for allowing quick and easy release and adjustment to a bicycle seat and/or bicycle wheels, while still allowing the seat and/or wheels to lock to the bike frame when the quick release lever is in the closed position. The device includes a standard plug lock combined with the lever of the quick release device. In the closed position, the lock can be engaged with a key, securely locking the lever closed and the seat and/or the wheels to the bicycle frame.

A bicycle component securing structure includes a shaft, a head, a lever and a pivot pin. The head has a recess with the shaft at least partially disposed therein. The lever has portions disposed on opposite sides of the head. The pivot pin couples the head and the lever to the shaft. The pivot pin has a cam section disposed between first and second end sections. The cam section is disposed within the recess to longitudinally move the shaft relative to the head in response to movement of the lever. The first end section is non-rotatably mounted in a first mating hole of the lever such that the lever and pivot pin rotate together. The first end section has a larger maximum transverse width than the second end section. The second end of the pivot pin is retained within the lever.

A quick-release system for a quick-release device, in particular for a cycle, such as a bicycle, the device being of the type including an axially extending skewer and an end support element mounted on a first end of the skewer adapted to be supported on a first tightening surface of the cycle. The quick-release system includes a tightening sub-assembly including a support surface and an actuation sub-assembly including a movable actuating mechanism, capable of axial rotation around the skewer and configured to transmit a tightening torque to the tightening sub-assembly when the device is being tightened. The system includes tightening torque limiting mechanism making it possible to limit the torque transmitted by the actuation sub-assembly to the tightening sub-assembly.

The invention relates to a quick release assembly for a bicycle, wherein the assembly comprises an axle having a first non-cylindrical end portion, a cylindrical central portion, and a second non-cylindrical end portion, wherein a diameter of one of the non-cylindrical end portions is larger than the diameter of the cylindrical central portion. The quick release assembly further comprises an insert having a non-cylindrical outer profile configured to be retained in a non-cylindrical opening and having a cam surface disposed therein, wherein the insert is sized to retain one of the non-cylindrical end portions of the axle therein. The assembly also includes a shaft sized to pass through the axle and having a cam follower on a first end and a handle on a second end, wherein the cam follower is configured to form a locking engagement with the cam surface upon an axial rotation of the handle.

A bicycle wheel securing structure includes a shaft member, a head member, and a lever member. The shaft member has a first end portion, a second end portion and a central portion disposed between the first and second end portions with a center axis extending between the first and second end portions. The head member is disposed on the second end portion of the shaft member. The lever member is operatively mounted to move the shaft member in an axial direction relative to the head member in response to movement of the lever member. The central portion of the shaft member has a radial thickness smaller than the first and second end portions.

A wheel quick release system for a bicycle or other wheeled vehicle where the wheel can be easily removed by a manual operation on only one side of the wheel hub but is prevented from unexpected separation at all times while engaged with the wheel. A laterally moving skewer mounted concentrically inside a hollow axle is equipped with a “non-touch” nut on one end and is spring loaded toward a quick release cam on the other end thereby always urging the nut against the adjacent dropout. To remove the wheel, the quick release cam is operated and the quick release side assembly is pushed axially inward and a safety mechanism is operated and held in this position while the wheel is removed from the fork dropouts. When the wheel is again inserted into the wheel fork, the skewer automatically locks onto the dropouts, and subsequently if the quick release cam is inadvertently left open by the user, the wheel will be somewhat loose but will remain safely inserted in the wheel mounts. In this way, if the bicycle or wheeled vehicle looks safe to ride, it is safe to ride.

A quick-release device includes a shank and a flange radially extending from one end of the shank. A ring is sleeved on the shank and engaged to the flange. A sleeve is co-axially connected and engaged to the ring. A washer is received in the sleeve. A shaft is co-axially connected to the shank and sequentially extending through the ring, the sleeve and the washer. A pivot is transversely mounted to a distal end of the shaft and abutting the washer. A lever is pivotally mounted onto the pivot for selectively forcedly and inwardly pushing the washer and engaged to the sleeve.
