Abstract: The present invention relates to a board 1 suitable for use in descending a snow slope. The board 1 has a generally flat elongate base 15, a forward portion 2 with an upturned leading edge portion 12, a user support portion 4 and a rearward portion 3 comprising at least partly independently movable left and right support portions 18, 19 extending generally alongside each other rearwardly from said forward portion 2.The base 15 has outer side edges 7, 8 of generally angular cross-sectional shape for biting into the surface of a snow slope during turning in use of the board 1. The side edges are furthermore concavely arcuate, in plan view, so that the board 1 is substantially waisted intermediate its ends 12 and 14 so that the board can proceed along an arcuate path when one of its side edges 8 is weighted and the other 7 unweighted.

Abstract: A snowboard toy is disclosed having an improved safety release foot harness. The toy has a semi-rigid ski platform having an upturned front end and a main body portion extending rearwardly from the front end. A number of strap retainers are located on the main body portion with one strap retainer located towards the rear of the main body portion and one located towards the front. The strap is secured at one end and has a free end passing through the strap retainers. The strap forms foot retaining loops and when the snowboard toy is in use the strap is pulled on the free end to create tension to secure a person's feet to the snowboard toy beneath the strap. Upon release of the tension in the strap the feet are also released.

Abstract: An ice skateboard has front and rear trucks with horizontal axles attached thereto for pivotal steering movement of the axles in response to tilting of the skateboard. Each of the horizontal axles has a pair of runner blades attached thereto. An auxiliary blade assembly is attached to each side of the skateboard between the front and rear trucks and in tandem with the runner blades attached to the axles. Each of the auxilary blade assemblies include a mounting arrangement which permits pivotal movement of the auxiliary blade relative to the longitudinal axis of the skateboard.

Abstract: A riding apparatus, such as a water ski board or snow ski board, in which the rider's feet are positionable within bindings formed on first and second riding plates. Each riding plate is positionable above a channel section formed within a rider support surface of the riding apparatus. Fasteners supported by each riding plate are releasably engageable with retaining elements installed within the channel section. After loosening the fasteners from the retaining elements, each riding plate may be repositioned angularly or longitudinally with respect to its channel section, thereby permitting the apparatus to be used with a variety of stances and leg spacings.

Abstract: A binding is provided which includes first and second distinct jaws which are rotatable about respective distinct axes of the body of a binding. The jaws are both biased by a common spring via one or more transverse arms having ends which abut the front portions of the respective jaws. Rotation of one of the jaws, and subsequent release of a boot retained thereby, effects compression of the spring and reduces the release threshold of the other jaw, thereby minimizing injury to a skier.

Abstract: A snow board comprises a runner and a support deck pivotally supported on and above the runner for pivoting about a longitudinal axis thereof.

Abstract: In a tractor towed chassis having a telescoping, articulated stinger, a two function locking mechanism is disclosed complementary to the non-articulating and articulating functions of the chassis. In the non-articulating function, the chassis hauls short containers, has the stinger telescoped to a non-articulating disposition and conventionally pivots with respect to the towing tractor at a fifth wheel. In the articulating function, the chassis extends to expose the articulated portion of the stinger, is locked at the forward portion to the towing tractor for articulation and when turning of the tractor relative to the chassis occurs the rear wheels turn to assist in turning the tractor towed chassis. The locking mechanism has two discrete locks, a bolster lock that is engaged only when the chassis does not articulate and a fifth wheel lock that is engaged only when the chassis does articulate.

Abstract: A chassis with a telescoping articulated stinger for receiving and hauling containers over 40 feet is disclosed where the chassis rear tandem wheels assist in steering. The chassis mounts conventionally and pivotally at a fifth wheel to a towing tractor with a forward bolster for supporting the forward end of a container. The chassis has a telescoping stinger connecting the rear set of tandem wheels with overlying rear bolster for conventionally supporting and towing short cargo containers, preferably of 20 to 40 feet in length. Where a container of greater than 40 feet is desired to be hauled on the chassis, the stinger is telescoped to expose an articulating joint and both bolsters are allowed to pivot with respect to the chassis. The towing tractor is locked to the chassis at the fifth wheel, and the articulated stinger adjusted in length for the desired lever arm to permit optimum tandem wheel steering.

Abstract: A universal shipping container chassis is disclosed wherein shipping containers of various lengths can be readily accommodated and securely held thereto for transit. A rear wheel assembly includes a load-bearing portion adapted to securely receive and support one end portion of a shipping container; a fifth wheel assembly also includes a load-bearing portion which is adapted to securely receive and support a second end portion of said shipping container. The fifth wheel assembly is coupled to a truck tractor such that the chassis may be readily towed. The wheel assemblies are coupled one to the other by an elongate extensible stinger that is readily adjusted in extent to bring the wheel assemblies closer together for shorter containers and to space the wheel assemblies further apart for longer containers. The stinger includes a locking mechanism for securing it to the wheel assemblies at locations thereby providing a selected extension of the stinger that corresponds to the shipping container's length.
