Abstract
A skewer assembly for a rack mount having a cam disposed against a cam follower actuable from an open configuration to a closed configuration, the skewer assembly further having a lock assembly integrated with the cam follower and a locking member located within a radial contact surface perimeter of the cam. The skewer further having a tightening assembly with a ratcheting nut which is incapable of being loosened when the skewer is placed in tension. Moreover, the skewer assembly covers the access holes to the internal hardware of the rack mount when inserted therein.
Claims16
A locking skewer assembly configured for entry through an aperture of a fork mount and receiving forks of a bicycle for mounting thereon, said skewer assembly comprising:
- a longitudinal skewer member having a cam end and an adjustment end each located on opposing ends of said member;
- said cam end having a cam disposed against at least one surface of a cam follower with said cam being rotatably moveable about a pivot point by a lever in communication therewith from an open configuration to a closed configuration wherein said cam follower is moved along said skewer member to a position closer to said adjustment end,
- said cam having a radial contact surface perimeter in contact with said cam follower, said surface perimeter extending from a first point of contact with said cam follower when said cam is in said open configuration to a second point of contact with said cam follower when the cam is in said closed configuration,
- said cam having a locking member located in an area between said contact surface perimeter and said pivot point in both said closed configuration and open configuration, and
- wherein said cam follower has a locking assembly integrated therein and being configurable to lock said locking member in place when said cam is in said closed configuration whereby movement of said cam and cam follower is prevented.
A fork mount comprising a locking skewer assembly received through an aperture of said fork mount, said locking skewer assembly configured for receiving forks of a bicycle for mounting thereon, said skewer assembly comprising:
- a longitudinal skewer member having a cam end and an adjustment end each located on opposing ends of said member;
- said cam end having a cam disposed against at least one surface of a cam follower with said cam being rotatably moveable about a pivot point by a lever in communication therewith from an open configuration to a closed configuration wherein said cam follower is moved along said skewer member to a position closer to said adjustment end,
- said cam having a radial contact surface perimeter in contact with said cam follower, said surface perimeter extending from a first point of contact with said cam follower when said cam is in said open configuration to a second point of contact with said cam follower when the cam is in said closed configuration,
- said cam having a locking member located in an area between said contact surface perimeter and said pivot point in both said closed configuration and open configuration,
- and wherein said cam follower has a locking assembly integrated therein and being configurable to lock said locking member in place when said cam is in said closed configuration whereby movement of said cam and cam follower is prevented.
