  • Patent number: 8360462
    Abstract: A foldable trailer is disclosed having the folding means provided by a winch that operates in conjunction with a lifting member enabling the trailer to be winched into an upright position for storage. The load bearing surface can be made of one section or two sections that fold together to allow for more compact storage. Through the lifting member the winch provides upward motion of the front of the load bearing surface while simultaneously causing the hingeably attached tongue to fold downward; continued winching will result in a vertically folded and storable position. The invention may be applied to a tilting trailer.

  • Patent number: 6640979
    Abstract: A motorcycle parking stand is disclosed that utilizes three shoes oriented to engage a motorcycle wheel at different points around the circumference of the wheel thus maximizing the stabilizing effect of the structure. The shoes are generally wedge shaped or of a shape that resembles the profile of the tire so as to come in contact with the outer edge of the treaded surface of the tire. The first two shoes are pivotally mounted to the stand structure and are fixed in relation to each other. A third shoe is affixed to the forward part of the stand structure to arrest the forward motion of the wheel and to provide support. Engagement occurs by pushing the motorcycle wheel into contact with the pivoting shoes which causes forward rotation of said shoes until the axle of the wheel is forward of the pivot point of the shoes thus enabling gravity to hold the wheel in contact with the front shoe.

  • Patent number: 6520521
    Abstract: A tilting trailer suspension which has forwardly disposed, independent swingarms pivotally attached to a trailer main platform and a second u-shaped perimeter frame attached to the rear portion of the swingarms and extending over the swingarms converging at a latching point on the trailer tongue. Each swingarm has a stub axle mounted at its forward end for wheel attachment. A spring is mounted between the forward end of each swingarm and the perimeter frame to provide suspension. Tilting is accomplished by unlatching the u-shaped perimeter frame from the tongue portion of the main frame and raising it so that the swingarms pivot about the connection to the main frame. The rearward end of the trailer platform drops to the ground at a low angle, while the u-shaped perimeter frame assumes an upwardly extending attitude.

  • Patent number: 5988402
    Abstract: A motorcycle stand uses a novel combination of components including a primary capture mechanism that consists of a transverse rod on which are mounted two vertical capture plates that translate inward as the motorcycle tire enters the stand. The capture plates are mounted for rotation orthogonally to the translation concomitantly with a tire contact plate. Translation of the plates is accomplished by the spring action and location of a pair of compressible pivot rods that have one end mounted forward and outward of the main rotation axis of the tire contact plate and the other end affixed to the sides of the capture plates. Forward rotation of the primary capture mechanism results in inward translation of the capture plates until they contact the tire side-wall. Further rotation results in compression of the springs in each pivot rod. A second, upper engagement shoe cooperates to ensure that the tire is fully captured.
