The present invention is for a tow hitch insert assembly that allows for natural dangling and swinging motion of an elongated member from a trailer hitch. The elongated member can be of a variety of shapes and in one version is a replica of testicles. The elongated member is coupled to an insert tube main body by a rod that extends through the tow hitch insert assembly. Surrounding the rod are springs on each side, sandwiching the elongated member, which allows for oscillation of the elongated member within the tow hitch insert assembly. In another version, the elongated member is secured via a slotted plate, and the elongated member has a spheroid top wider than the slot of the slotted plate, which permits the elongated member to slide and rotate within the tow hitch insert assembly.

The trailer hitch signaling device is a visual signaling device. The trailer hitch signaling device is configured for use with a vehicle. The vehicle is further defined with a hitch. The trailer hitch signaling device is configured to attach to the hitch. The trailer hitch signaling device physically moves to indicate an action selected from the group consisting of: 1) the vehicle is braking; 2) the vehicle is preparing to turn left; and, 3) the vehicle is preparing to turn right. The trailer hitch signaling device further comprises a lamp. The lamp generates illumination to further signal that the vehicle is braking. The trailer hitch signaling device comprises the puppet and a control circuit. The control system is contained within the puppet. The control system is electrically connected to the vehicle. The control system further moves the limbs of the puppet and illuminates the lamp.

A plug for insertion into a through hole of a king pin coupler plate of a trailer includes a body defining an axial direction and having an outer surface defining a perimeter with a distance around the perimeter. A plurality of pliable ears extend from the outer surface. The ears are each individually aligned in the axial direction. The ears each have a width that is less than ten percent of the distance around the perimeter of the outer surface of the body.

A coupling device for coupling a first vehicle to a second towed vehicle includes a pillar for mounting to a towbar of the first vehicle, the pillar defining a primary longitudinal axis and including an upper portion, a lower portion adapted for engagement with the towbar of the first vehicle, and an intermediate portion including a radially protruding locking flange, a coupling body adapted for sleeved engagement with the upper portion of the pillar, the coupling body including at least one locking device for locking the coupling body to the locking flange of the pillar, and a rotary cap operatively associated with the at least one locking device and adapted for rotation relative to the coupling body. Rotation of the rotary cap causes the locking device to pivot between at least a locked position in which the coupling body is prevented from disengaging from the locking flange of the pillar and an unlocked position in which the coupling device is free to disengage from the locking flange of the pillar.

A ball hitch cover. The ball hitch cover includes a front tab and a pair of side tabs connected to a lower end of the front tab. Each side tab includes a first edge having a first width and a second edge having a second width, wherein the second edge width is greater than the first edge width. A pair of rear tabs are disposed opposing the front tab, such that each rear tab is disposed adjacent to the second edge of one of the side tabs of the pair of side tabs. A length of each rear tab of the pair of rear tabs is greater than a length of the front tab. The ball hitch cover is flexible and configured to conform to the shape of a ball hitch and is securable thereto via an adhesive disposed on an inner side of the ball hitch cover.

A trailer yaw sensing apparatus is provided. The trailer yaw sensing apparatus includes a housing, a yaw sensor, and a docking station. The housing is configured for installation on a trailer. The housing defines apertures that are configured to engage fasteners for mounting yaw sensors in a plurality of orientations. The yaw sensor includes an external casing and is disposed within the housing. The docking station is affixed to the housing and is configured to receive a trailer-to-vehicle electrical connector.

A trailer hitch spring bar cover system for providing clean and safe storage of a trailer weight distribution system including spring bars and towing balls. The cover for a trailer weight distribution spring bar generally includes a first body and a second body movably connected to the first body. Each of the bodies have a first end, a second end, a perimeter edge, a cavity, and a cutout near an end of the body. The cover has an opened state adapted to receive or remove a greased portion of the spring bar. The cover also has a closed state to substantially enclose a greased portion of the spring bar.

A trailer hitch cover assembly, which includes an inflatable object capable of withstanding about 2000 pounds per square inch internal pressure, a first attachment plate disposed within the inflatable object, a second attachment plate disposed in physical contact with but external to the inflatable object, a housing comprising a plurality of threaded apertures extending therethrough and dimensioned to be received by a trailer hitch receiver, where a corresponding plurality of threaded members are attached to the first attachment plate, extend outwardly from the first attachment plate through a surface of the inflatable object, extend through the second attachment plate, and intermesh with the plurality of threaded apertures.
