  • Fifth wheel trailer lock
    Patent number: 10406874
    Abstract: A fifth wheel trailer lock for preventing a fifth wheel release handle from being operated to unlock a fifth wheel of a load hauler from a load supported by the fifth wheel. The fifth wheel trailer lock generally includes a handle mount that mounts on and releasably locks to a fifth wheel release handle in a predetermined orientation, a lock extension that extends outwardly from the handle mount into proximity with a stationary structure of the fifth wheel, and a fifth wheel catch on the lock extension adapted to engage the stationary structure of the fifth wheel when an attempt is made to operate the release handle. The engagement of the stationary structure of the fifth wheel by the fifth wheel catch prevents the release handle from being operated to unlock the fifth wheel from the supported load.
