  • Patent number: 7690673
    Abstract: A ball hitch coupler permits self-latching with a ball hitch. The ball hitch coupler has a housing with a generally downwardly facing open socket for receiving a ball hitch. A ball clamp member within the open socket is attached to an adjustment lever by a clamp rod that extends through a top surface of the housing. A camming surface provided on the lever causes the clamp rod to pull the ball clamp member upwardly and outwardly from the socket as the lever is pivoted to an open position. When the lever is in a neutral ready position, a ball hitch may be inserted into the socket and will automatically be coupled with the ball hitch coupler without further adjustment.

  • Patent number: 7469920
    Abstract: A kingpin lock including a body having a substantially frustoconical portion and a kingpin cavity having a central axis, a slide channel having a central axis and a sleeve channel having a central axis. The slide channel intersects the kingpin cavity such that its central axis is substantially offset from a radius that extends outwardly from the central axis of the kingpin cavity. The sleeve channel intersects the slide channel. A slide member is shiftable between an engaged position extending partially into the kingpin cavity and a disengaged position where the slide member does not engage the kingpin. A locking member is shiftable between an engaged position and a disengaged position such that the locking member engages an indentation in the slide member so that the slide member is secured in the engaged position and the kingpin lock is secured to the kingpin.

  • Patent number: 7467805
    Abstract: The present invention provides a locking device for a hinged, body and cap trailer coupler to prevent unauthorized use of an unattended and unattached trailer. The device consists of a cylindrical bar member joined to an elongated tongue member. The elongated tongue member is sized for insertion between the body and cap portion of a trailer coupler in the open position such that the cap portion is forced against the sliding collar of the trailer coupler, preventing the trailer coupler from closing on the ball of a tow vehicle. The elongated tongue member provides a slotted hole portion to receive the shackle of a padlock to lock the system in place.

  • Publication number: 20080284135
    Abstract: A system for protecting a trailer coupler contains a first arm rotatably connected to a second arm. The first arm contains a top portion, a side portion, and a bottom portion, the top portion of the first arm containing a first opening. The second arm contains a top portion, a side portion, and a bottom portion, wherein the top portion of the second arm contains a first opening. The trailer coupler fits within the system and aligning the said first opening of the first arm and the first opening of the second arm forms a system top portion opening that allows access to a hitch of the trailer coupler while not allowing access to other top portions of the trailer coupler or side portions of the trailer coupler.

  • Patent number: 7448236
    Abstract: An adjustable coupler lock for locking a trailer hitch such that a trailer cannot be removed from a vehicle. The coupler lock comprises a lock body with a locking mechanism and a locking plate, and also comprises a shaft having a narrow and a flange end, and also having multiple recesses along the length of the shaft for engagement with the locking plate of the lock body. The recesses along the length of the shaft have a vertical edge which engages the locking plate such that the lock body cannot be removed from the shaft without unlocking the locking mechanism. The recesses also have a tapered edge that allows for slidable movement of the lock body along the shaft, without unlocking the locking mechanism, for the purpose of adjusting the lock to the size of the latch.

  • Patent number: 7448640
    Abstract: A pin-engaging drawbar wedge and lock plate wedge are designed to mount in the drawbar of a trailer hitch or alternative trailer and accessory hitch or receiver assembly. The pin-engaging drawbar wedge includes a bolt extending into the drawbar and in one embodiment, having the bolt head secured to a wedge positioned beneath the locking pin extending transversely through the receiver and the drawbar. Alternatively, the bolt threads into a nut secured to the wedge. The wedge bevel face or surface engages the locking pin and the locking pin openings are typically elliptical or elongated in the drawbar, to facilitate rotating the bolt or nut and forcing the wedge against the locking pin, thus tightening the drawbar against the hitch receiver. In another embodiment the bolt extends through the drawbar and a slotted guide plate to a lock plate and rotating the nut forces the lock plate against the locking pin and the guide plate and tightens the drawbar against the hitch receiver.
