Abstract: A snowmobile ski comprises a body having a pair of rails laterally spaced from one another and interconnected at a tip. A spindle assembly connects the ski to suspension elements of the snowmobile. The spindle assembly has a pair of legs connected to respective rails to allow snow to pass between the legs.

Abstract: The present invention provides a retractable wheel system for snowmobile skis. The retractable wheel system of the present invention may be installed on a snowmobile ski without affecting its structural integrity by installing the system on the reinforced portion of the snowmobile ski. When a user circulates in a path with little or no snow, the retractable wheel system is positioned in the extended configuration by the user and the system will automatically return to the retracted configuration when the user returns in a snowy zone. This is realized by using a pre-tensioned spring that will reposition the wheel in the retracted configuration. The spring transmits a rotational movement to the member on which the wheel is fixed.

Abstract: A speed sensor for a wheel end that has an interior that is substantially isolated from an atmosphere around the wheel end. The speed sensor is carried by a housing of the wheel end for monitoring the rotation of the wheel end and indicating the angular velocity of the wheel end. The speed sensor includes a cable leading from the sensor to a location remote from the wheel end and further includes leads that transmit a signal and a sheath that encloses the leads. The sheath is open enough to allow a fluid to flow through its interior. A vent channel provides communication between the interior of the wheel end and the interior of the sheath on the cable.

Abstract: A convertible sled for use by a rider. The convertible sled includes a body, a mounting unit coupled to the body for coupling plural wheels or plural sledding members, and a steering unit moveably coupled to the body at the front portion of the body such that, when the convertible sled is arranged in a first configuration, the steering unit is operatively coupled to at least two of the plural pairs of wheels, as steering wheels, for steering the convertible sled. Further, the steering wheels on a first side of the body pivot about a first common point and the steering wheels on a second side of the body pivot about a second common point different from the first common point. Moreover, when the convertible sled is arranged in the second configuration, the steering unit is operatively coupled to a portion of the plural sledding members for steering the convertible sled.

Abstract: A gooseneck trailer coupler lock which disables normal coupler operation by restricting movement of the lower latching plate of the coupler when the coupler is placed in the fully closed position. The locking device is a single piece of hardened metallic material which inserts into a gap formed between the upper coupler plate and a band attached to the lower latching coupler plate. The locking device is secured in place with a block type lock or other theft resistant lock. When the locking device is installed, the coupler opening is secured in a position which will not accept a typical towing ball without first removing the locking device.

Abstract: A typically one-rider non-powered sports/recreational vehicle has a main body that can be easily converted between a wheeled coaster-wagon configuration and a snow-sled configuration with runners. Typically there are four wheels or four runners: two at front, steerable from a handlebar, and two fixed at rear. For braking in the coaster-wagon configuration, a pair of brake shoe pads, attached to the handlebar, press against the front tires to act as brake shoes when the handlebar is twisted radially via a pair of user handgrips. In the snow-sled configuration, a braking panel, attached centrally on the handlebar, moves downwardly to brake by engaging oncoming snow. In normal use as a coaster or sled, when not braking, this braking panel is nested in an unobtrusive location immediately beneath the front of the main body platform, retained there by spring action that also provides braking hold-off in the coaster-wagon configuration.

Abstract: A skateboard simulator provides a stable platform for wheeled skateboard-type actions. The simulator has a pair of spaced truck-like elastomeric support means mounted to a deck to simulate the response of a conventional skateboard to user actions. Spaced contact lobe elements provide a frictional contact with the ground while flexing in response to user action to simulate the response of wheeled skateboard. The support means are preferably of a unitary urethane construction with the contact lobe element portions being of a hollow configuration.

Abstract: A tracked vehicle (18), or a kit (10) for converting a standard bicycle (14) into a tracked cycle, includes a track assembly (22) with a bogie assembly (84) for riding on snow, mud, sand, etc. The track assembly includes a continuous track (60) movably disposed about a drive wheel (64) coupled to a frame (34) of the vehicle or bike, and a bogie wheel (68) disposed rearward of the drive wheel. The bogie assembly includes a compliant and resilient arm (80) coupling the bogie wheel to the frame of the vehicle or bike. The arm exerts a force against the bogie wheel, which forces the track towards the riding surface.

Abstract: A snowboard is disclosed whose base is relatively thick in the mounting zones beneath each of the rider's feet and relatively thin between the two mounting zones. Thus, with normal loading applied through the rider's feet to the snowboard, the board will bow into a reasonably good approximation of an arc having a constant radius. Consequently, the portions of the snowboard coming in contact with the surface of the snow will substantially lie on segments of a circular arc, and the back half of the snowboard will substantially follow in the track of the front half of the snowboard. This is achieved by controlling the flexural rigidity in the mounting zones and in the center section between the mounting zones. The curvature of the snowboard in response to the application of forces by its rider is a function of the Area Moment of Inertia (I) of the transverse cross-sectional areas along the snowboard's length. In turn, the Area Moment of Inertia is a function of the geometry of the transverse cross-section.

Abstract: A wheel support device having a base member, a pair of supporting arms attached to the base at each end thereof and attachable to a wheel hub in a common plane which extends through a longitudinal axis defined by the pivotal points of a pair of rotatable casters attached to the base member in spaced relationship to each other. Each caster assembly includes a protective skirt disposed to prevent the engagement between foreign objects and the casters.

Abstract: This conversion kit provides for converting a conventional child's wagon into a sled and includes front and rear runners mounted for limited rotation on the wagon wheel axles in place of the wheels. The wagon towing handle is replaced with a sled tow bar and a longitudinally adjustable deck is removably attached to the wagon body.

Abstract: A snow assembly for conversion, for snow operation, of a normally road operable vehicle includes ski and track assemblies which are adapted to be mounted on the vehicle in place of the tires normally mounted thereon for road operation. The ski assembly includes a raise bracket which is mounted to a brake housing of the vehicle by the bolts which normally mount the tire to the brake housing and a ski which is mounted at the bottom of the raise bracket such that the ski is rotatable relative to the raise bracket to vary the angle between them. The raise bracket is preferably pivotally linked to the vehicle to stabilize the bracket in the direction of movement of the vehicle. Pneumatic tires are also preferably positioned on the ski assembly to enable operation of the vehicle both in snow and on open road when the snow assembly is installed on the vehicle.

Abstract: A front support member is pivotally affixed to the undersurface of a body-supporting board close to the front and equidistant from the sides thereof. A pair of rear support members are affixed to the undersurface of the board in spaced parallel relation close to the rear and equidistant from the sides thereof. Each of the support members comprises a block having a bore formed therethrough spaced from and parallel to the undersurface of the board. A front ski member and a pair of rear ski members have spaced ears with coaxial bores formed therethrough. The ears are spaced a distance from each other sufficient to accommodate the blocks of the support members therebetween with the bores of the block coaxial with the bores of the ears. Bolts pass through the bearings in the bores of the ears and the bores of the blocks to removably affix the ski members to the support members in a manner whereby the ski members are rotatable in planes perpendicular to the undersurface of the board.
