Abstract: A replacement bumper for a snowmobile ski is provided and methods for using the same. The replacement bumper has an abutment surface that makes contact with a spindle of a snowmobile in order to increase the contact surface area of a rear portion of a snowmobile ski and the ground and/or increase the weight being distributed on the rear portion of the snowmobile ski, which prevents the darting or tracking of the snowmobile ski. Also, includes is a method for removing an OEM bumper from a snowmobile ski assembly and installing a replacement bumper into said snowmobile ski assembly.

Abstract: A snowmobile ski runner has a flat ski runner body. The flat ski runner body has a generally uniform width, a front flat wall at a front thereof, and a rear flat wall at a rear thereof. The front and rear flat walls are parallel to each other. A snowmobile ski assembly having the ski runner and a snowmobile having the snowmobile ski assembly are also disclosed.

Abstract: A board is provided particularly for supporting a front of a snow vehicle. The board is provided alone as a single board for a forward portion of the snow vehicle with the board capable of floating upon soft snow. The board includes a mounting bracket on an upper surface for mounting to a chassis of the snow vehicle. The running surface opposite the upper surface floats the board upon the snow or other support surface and preferably includes a central fin and a pair of skegs extending down from the running surface. Side edges of the board can engage the snow to allow turns to be carved by the snow vehicle. The central fin can be adjusted in position and depth and has various different configurations to provide optimal steering control of the snow vehicle through the board.

Abstract: A portable assembly includes a multi-level housing having a vertically oriented back wall and an elongated rectilinear axle conjoined thereto. The housing further includes an elongated handle having a lower end portion monolithically formed with the back wall. A plurality of rotatable wheels operably communicate with the axle end portions and a plurality of coextensive shelves are conjoined to the back wall. The assembly further includes a mechanism for testing a variety of battery charging systems. The testing mechanism includes a plurality of power receptacles integrally connected to the back wall and spaced above a top one of the shelves. A battery-charger testing device is nested on one of the shelves for testing 48 volt club car power drive chargers. The battery-charger testing device is provided with a plurality of fuses for testing 36 volt and 48 volt circuits respectively.

Abstract: A snowmobile steering mechanism adapted to place higher pressure on the outside ski than on the inside ski when the snowmobile enters and exits turns, said steering mechanism being adapted to include the suspension in the steering action of the snowmobile causing the snowmobile to automatically lean into a turn improving the ability of the snowmobile to enter and exit turns in comparison to a snowmobile without the inclusion of the suspension in the steering action of the snowmobile.

Abstract: A snowskateboard includes a support deck having an upper side and a lower side opposite the upper side. First and second trucks are mounted to the lower side. The trucks include rotatable yokes having axles. A set of first runners is disposed over the first yoke axle. A set of second runners is disposed over the second yoke axle. A first biasing mount is mounted in each of the first runners and disposed over the first axle. The first biasing mounts each have first biasing members configured to bias in a torsional direction relative to the first truck axle. A second biasing mount is mounted in each of the second runners and is disposed over the second axle. The second biasing mounts each have second biasing members configured to bias in a torsional direction relative to the second axle.

Abstract: A ski-snowboard device has a support board for the user and a plurality of ski pairs mounted to the underside of the board. The ski-snowboard has a steering and suspension system, connecting the skis in each pair, to provide paired steering and independent suspension. Each steering and suspension system preferably comprises two pivoting generally-V-shaped arms connecting the board to the skis, wherein the V-shaped arms are spaced apart at their top end connections to the board, and each connect to different portions of rocker members that hold the skis. The V-shaped arms pivot relative to the board, and the rocker members pivot relative to the arms and also relative to the skis. Shock-absorbing/biasing systems cushion vibrations and tune the suspension and steering. Thus, the skis move right and left, move to their inside edges, and swing forward and rearward, to properly steer the ski-snowboard right and left and up and down terrain, for enhanced handling and control by the user.

Abstract: A pair of runner attachments for use in retrofitting an existing scooter into an all-season toy. The runner attachments having a runner on a lower side and are securely mounted on an upper side to the axle of the vehicle's wheel supports in a manner such that the runner is restrained from plowing into the snow or ice. The runners may be configured as a skate or ski.

Abstract: A towed vehicle is towed behind such recreational off-road vehicles as snowmobiles and all terrain vehicles (ATV's). The vehicle has a body that is rotationally molded of low density polyethylene. It has an outer shell mounted on a vehicle frame and an inner shell suspended on the inside of the outer shell. The outer shell peripheral wall is formed to provide some resiliency to cushion the inner shell. The suspension of the vehicle includes a trailing arm and a one-quarter elliptical spring biasing the trailing arm away from the vehicle.

Abstract: A sledge or equivalent transporting base, consisting of a frame (1) and of thereinunder mounted travelling members such as runners (2), with reference to which the frame is movable in the direction longitudinal to the sledge. To the runner (2) has been pivotally attached an arc-shaped rolling member (3) with the center-point of its radius at the pivotal point and which is free to roll along an opposed counterface (5) on the frame (1). With the aid of the invention, sledge runners which have frozen fast to snow or ice can be easily freed by first backing up so that the load rolls into its rear position, whereafter the sledge is started, whereby with the aid of the load's mass the runners are jerked free from frozen-on snow and ice.

Abstract: Suspension and steering assembly for a snowmobile including at least one ski for supporting a front portion of its body and also for steering the snowmobile, comprising a strut means capable of telescopically expanding and contracting, spring means, a shock absorber and a steering arm means. The strut means includes a first or inner strut member and a second or outer strut member, the first strut member being slidably mounted in the second strut member. The first or inner strut member is pivotally connected at its lower end to the surface of the ski. The second or outer strut member is rotatably supported to the body of the snowmobile. The spring means is operative to urge the two strut members to slide out of each other. The shock absorber is pivotally connected at one end to the ski and at the other end to the second strut member of the strut means, and extends obliquely with respect to the strut means.

Abstract: A strut-type steering ski suspension having minimal height for a given stroke. The suspension includes shock-absorber means with a movable cylinder and a fixed rod, the rod being fixed relative to the frame of the snowmobile. A ski is mounted to the lower end of the movable cylinder. A bias spring is incorporated in the suspension, which bears in compressive opposition between the lower portion of the movable cylinder and the rod or some other structure which is fixed to the frame, thereby utilizing otherwise "dead" space for the spring, and shortening the length of suspension needed for a given stroke length.

Abstract: A light weight trail groomer is supported at its rear end on each side by a pair of longitudinally aligned skis connected to respective arms of a bracket pivotally mounted on a main frame element. The frame structure is arranged for connection at its forward end to a towing vehicle and includes a scraper blade structure the height of which can be adjusted by independent adjuster means connected between an auxiliary frame structure and each one of the main frame elements.
