An anti-rattle hitch device is described. A rotating barrel pin is positioned proximate to the normal accessory port of receiving hitch housing. The pin cooperates with resilient bushings that are engineered to compress in overload situations, while urging the accessory drawbar flush against the upper, inner facing of the housing when the device is engaged under normal conditions. The resulting apparatus prevents unwanted rattling and play of the hitch and accessory without the need for loose or removable parts.

A weight distribution hitch system comprising an attachment member with a forward end configured to rigidly attach to a vehicle and a rearward end extending rearwardly toward a trailer, the rearward end comprising an upper portion with a ball mount configured to pivotably attach to a trailer coupler; a lower portion with a barrel coupling allowing pivoting about a vertical access, but not allowing pivoting about a horizontal access; and a moment bar comprising a moment bar forward end fixedly attached to the barrel coupling and a moment bar rearward end wherein the moment bar imparts a forward moment on the vehicle when an upward force is applied to the moment bar rearward end is disclosed.

Disclosed embodiments include apparatuses, vehicles, and methods for a displaceable tow hook. In an illustrative embodiment, an apparatus includes a tow hook configured to extend from a surface of a vehicle in a first direction. The tow hook includes a receiving section configured to receive a towing line and a securing section configured to extend away from the receiving section. A positioning mount is configured to secure the tow hook to the surface of the vehicle and to release the tow hook in response to an impinging force on the tow hook in excess of a predetermined threshold. A load-bearing structure is configured to mechanically connect the securing section to a structural component of the vehicle. The tow hook and the load-bearing structure are configured to support a force having a component in the first direction that is at least equal to the towing weight of the vehicle.

A weight distribution system used with a hitch on a vehicle and a trailer, the weight distribution system comprising a jack with a foot attached to and configured to raise and lower a front portion of the trailer; a moment bar with a forward end attached to the hitch so as to pivot about a generally vertical axis, and a rearward portion, the moment bar configured to exert a forward moment on the vehicle in response to an upward force on the rearward portion; an engagement member positioned between the jack and the rearward portion, whereby the jack can exert the upward force on the rearward portion; wherein the engagement member comprises at least one arced surface whereby the engagement member maintains the upward force on the rearward portion despite vertical or horizontal pivoting between the vehicle and the trailer is disclosed.

A trailer coupler assembly and methods of use are provided that includes a ball coupler, a rod member having a first end and an opposite second end, a trailer frame, a first pivot connection pivotably connecting the first end of the rod member to the ball coupler, such that the rod member can rotate within a vertical plane relative to the ball coupler, and a second pivot connection pivotably connecting the rod member to the trailer frame, such the trailer frame can rotate around the rod member. The trailer coupler assembly also includes a lock out member that is configured to releasably engage the first pivot connection to thereby restrict pivoting of the rod member relative to the ball coupler.

In an automated guided vehicle, a connection mechanism includes a connecting part and a movable part, and is connected to an object by the connecting part. When the connecting part is in a first state and the movable part is at a first position, an end portion on the other side in a first direction of the connecting part contacts a surface on one side in the first direction of the movable part or penetrates the movable part in the first direction to protrude toward the other side in the first direction with respect to the surface on one side in the first direction of the movable part. When the connecting part is in the first state and the movable part is at a second position, the movable part is away from the connecting part. A force applied to the movable part maintains the movable part at the first position.

A trailer retainer assembly having a riser section extending above a ball mount area and a retainer member arranged to move along the riser section from an upper position to a lower position; wherein when the retainer member is placed in a lower position it at least partially covers the ball mount area such that a trailer coupler secured to the ball mount area is retained by the retainer member.

A ball-style hitch safety connector apparatus with a spoon safety connector made, as well as alternative designs, is disclosed herein. In an embodiment a spoon element is secured on the underside of the hitch, the spoon element including a spoon- or cup-shaped portion along with a handle. This spoon element presses up on the bottom of the ball assembly, in particular the underside where the nut and bolt are located that secure the ball to in place.

A weight distribution hitch system used with a hitch on a vehicle and a trailer, the system comprising a jack with a foot and a motor configured to raise and lower a front portion of the trailer; a moment bar with a forward end attached to the hitch so as to pivot about a generally vertical axis, and a rearward portion, the moment bar configured to exert a forward moment on the vehicle in response to an upward force on the rearward portion; an engagement member configured to increase the upward force on the rearward portion of the moment bar upon movement of the jack in one vertical direction and to decrease the upward force upon movement of the jack in an opposite vertical direction; a sensor configured to determine at least one of current and voltage across the motor, to thereby infer the upward force on the rearward portion; and a switch configured to turn the motor on or off depending on the inferred upward force is disclosed.
