| 24 | Ski and mount for four wheel vehicle | US52642 | 1987-05-20 | US4754832A | 1988-07-05 | John W. Allen; Douglas D. Banghart |
| A single ski is disclosed for central mounting under a four wheel vehicle, preferably a vehicle having four wheel drive. This single ski is mounted to the underside of the vehicle and includes a jacking mechanism for raising and lowering the ski in parallel relation with respect to the snow covered ground. The single ski extends longitudinally of the vehicle, centrally between the wheels on the left side of the vehicle and the wheels on the right side of the vehicle. The length and width of the ski is sufficient to remove substantially equal weight from both the front and rear tires of the vehicle. The surface area of the ski is sufficient to maintain the depth of the ski at a level no lower than the lowest point of the tires in soft or powder snow. In operation, the ski is lowered a sufficient distance to remove weight evenly from the wheels of the vehicle to an extent that the tires no longer accumulate a blocking drift of snow in their path of advance. Thereafter, the driving wheels provide propulsion and some support while the ski provides the requisite lubrication for firm, safe and stable support over the snow. The tires of the vehicle co-act with the single ski to produce driving and steering outriggers to prevent capsizing of the vehicle. Provision for steering of the vehicle is made either by conventional steering of the front steering wheels or alternately by providing for articulation of the vehicle supported ski responsive to vehicle steering. | ||||||

| 34 | Trailer for personal motorcraft | US649741 | 1991-02-01 | US5119752A | 1992-06-09 | Mark Doherty |
| The personal motorcraft trailer has a lower shell which is capable of flotation and planing on a body of water. An upper shell has a lip which fits over the edge of the lower shell forming a sealed pod in which gear and supplies may be stored. At least a portion of the upper shell is openably attached by a hinge. The upper shell has two recessed areas in its upper surface, the rear recessed area being deep enough for holding fuel containers and the forward recessed area being relatively shallow and concave to accept gear such as surfboards or skis which are held in place by elastic cords stretched across the gear from hooks on the sides of the upper shell. The trailer is towed behind the motorcraft by a tongue the prongs of which attach at two clips, one on either side of the lower shell. Each prong of the tongue catches under the lip at the front of the trailer to prevent the trailer from digging into the water, causing it to flip. The shells of the trailer are molded of lightweight plastic or similar polymer to make the trailer easy to lift and transport. In an alternate embodiment for use with snowmobiles, the same structure as above is fitted with skis or rails on its bottom surface to permit the trailer to move smoothly through snow or on ice. | ||||||

| 36 | Front suspension and steering system for cycles and motorcycles having two interdependent points of support on the ground | US203957 | 1980-11-04 | US4375293A | 1983-03-01 | Francisco Solbes |
| The present invention relates to a suspension and steering system enabling the road holding, braking efficiency and safety of presently known cycles and motorcycles of all types, on wheels or on skis, to be increased, while maintaining their capacity to bank when cornering, their handling ability and small dimensions. This system is composed of the combination of two sub-systems:--the suspension sub-system intended to carry two wheels or two skis, comprises: (a) a mechanism composed of two forks, two pairs of guide shafts, and two supports. The forks move over the guide shafts which are fixed to the supports; (b) a mechanism composed of a support, a rocking arm and a handle bar. This arm rocks on the axis of the support and allows the interdependent displacements of the forks;--the steering sub-system is intended on the one hand to carry the above mentioned mechanisms of the suspension sub-system and on the other hand to be articulated on the frame at the steering column and the reinforcing arm. It is composed of the devices which form the central shaft. | ||||||
