Abstract: A structure for use with a trailer tongue including two pairs of opposed sidewalls interconnected to one another to form an integral hollow rectangular structure that is adapted to receive and be secured to an end of a first rectangular tongue member. Each sidewall rotatably carrying a roller, at least a portion of each roller positioned in the interior space of the rectangular structure to substantially prevent contact between the inside surface of the rectangular structure and an outside surface of the second rectangular tongue member. The rectangular structure including a retainer for retaining a latch in a latch installed position, the retainer permitting selective actuation of the latch between the latch installed position and a latch uninstalled position by hand.

Abstract: A nonremovable linkage for securing a rack assembly to a frame, the linkage securing or automatically securing the rack assembly to the frame at a first position in response to the rack assembly returning to the first position from a second position.

Abstract: An elongated member pulling device including a support surface and a reel assembly for rotatably carrying a take-up reel about a first axis for receiving an elongated member, the reel assembly rotatably carried by the support surface about a second axis. A guide device including a plurality of rollers defining a closed geometry for guiding the elongated member toward the reel assembly. In response to the elongated member being guidingly received through the guide device and rotatably collected by the take-up reel, the reel assembly being selectably oscillatingly rotatable about the second axis to permit even winding of the elongated member on the take-up reel.
