Abstract: A fifth wheel hitch includes a locking member that engages surfaces of a pair of jaws to retain the jaws in a closed position. A release handle is operably connected to the locking member whereby movement of the release handle shifts the locking member out of engagement with the jaws to permit movement of the jaws to an open position. A ratchet type mechanism retains the locking member in an engaged position relative to the jaws and compensates for wear of the components and/or differences in size between kingpins.

Abstract: A fifth wheel slider assembly includes a hitch plate with a throat for receiving a king pin of a trailer, and a slider assembly that includes at least one rack member having a first side and a second side and supportable above a vehicle frame. The slider assembly further includes a first portion including a guide plate slidably abutting the second side of the at least one rack member, and an engagement assembly releasably engaging the at least one rack member at incremental points along a length of the at least one rack member, thereby selectively positioning the hitch plate with respect to the at least one rack member, and a second portion including at least one support bracket pivotably supporting the hitch plate, slidably abutting the first side of the at least one rack member, and readily releasably coupled to the first portion of the slider assembly.

Abstract: A kingpin assembly comprises a housing having a recess located therein, a collar member operably coupled to the housing, and an integral single-piece kingpin having at least a portion located within the recess of the housing, wherein the housing and collar cooperate to rotationally secure the kingpin within the recess of the housing, and wherein the kingpin provides a sole rotational support for the kingpin with respect to the housing and the collar.
