  • Patent number: 10639950
    Abstract: A torsion trailer coupler is affixed to a trailer between the tongue and an adjustable coupler. The torsion trailer coupler has a trailer side that affixes to the trailer and a coupler side that affixes to the adjustable coupler. The trailer side has torsion tubes that carry torsion bars and the coupler side has torsion tubes that carry torsion bars. The torsion bars between the trailer and coupler side are connected with torsion arms. The torsion trailer coupler moves between an unloaded position where the torsion bars and arms are at rest and a loaded position where force is applied between the sides and the torsion bars rotate about their central axes. The torsion bars, arms and sides cooperate to absorb transient forces between a towing vehicle and the tongue of the trailer.

  • Patent number: 10486728
    Abstract: A collapsible dolly assembly includes a pair of frames that are each selectively urged between a deployed position and a collapsed position. A pair of rear wheels is rotatably coupled to the frame to roll along a support surface. A pair of front wheels is rotatably coupled to the frame to roll along the support surface. A dolly is hingedly coupled to the frame to support an object thereby facilitating the object to be transported along the support surface. A pair of skid units is movably coupled to an associated one of the frames. Each of the skid units is selectively positioned in a deployed position. In this way each of the skid units frictionally engages a staircase thereby facilitating the object to be urged upwardly and downwardly along the staircase. A braking unit is movably coupled to the frame to selectively engage the staircase when the skid unit is positioned in the deployed position. Thus, the braking unit retains the object at a selected point along the staircase.
