The rear board member preferably overlaps the front board member so that the front board rearward end is underneath the rear board forward end to minimize drag at the joint when the snowboard moves over snow in a forward direction.

Abstract: An articulated two-section snowboard has a first and second section joined together for twisting and oscillation. Each section has an upper surface, a lower surface and an outer portion and an inner portion. A flexible connector joins the inner portions of the first and second sections and a pair of bindings for securing the feet of a user to the upper surface of the first and second sections.

Abstract: A two-piece apparatus for sliding over a surface. The device includes forward and rear runners connected by a linkage which allows a user to increase deviation of the runners from a horizontal plane at the same time that a deviation from the longitudinal axis of the apparatus occurs. Thus, the user can tilt or edge the runners at the same time that a turn is being implemented. The board provides a narrower waist section than the leading or trailing sections on each of the forward and rear runners. In addition, at maximum articulation of the runners, a substantially smooth arc is formed along the inner edge of the runners so that optimal cornering and shorter radii may be achieved. Preferably, each of the runners includes a set of fins along a rearward edge so that the device may bite into the surface more aggressively.

Abstract: An articulated two-section snowboard includes separate front and rear sections joined together for articulation and oscillation, each section having a binding for one foot. In a preferred embodiment, the joint between the two sections is achieved by one or more flexible straps. The front end of the strap being attached to the rear end of the front section and the rear end of the strap being attached to the front of the rear section, the strap preferably passes through openings formed for the purpose in the front of the rear section. A spacer may be provided to keep the rear section from riding up over the front section, and a quick-connect and disconnect latch may be provided to separate the sections for purposes of storage or replacement of a section.

Abstract: A ski control system incorporating carve control amplification to activate by deployment of auxiliary ski control surfaces, such as a probe assembly resiliently mounted on the ski at or near the center of pressure of the ski, and which functions when deployed to impose control forces on the ski in proportion to the degree of carve of the ski.

Abstract: Presented is a method and apparatus that permits a skier to control the speed at which he descends a ski slope. In terms of structure, the invention includes a pair of probes mounted on each ski that protrude below the running surface of the ski and thereby drag in the snow. The probes may be controlled as to the depth of penetration of the snow either before the skier starts his run, or during his descent. Having deployed the probes, added manueverability control is achieved merely by conventional body movements which affect the depth to which the probes penetrate the snow.

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 paired, sporting, ski-steering device for use with a pair of skis with the skier's feet locked in position by standard ski bindings, providing the skier with an upright handlebar for each ski, both skis being totally independent from one another. The handlebars are attached to the front of each ski at mid-position between the toe piece of the standard ski binding and the front tip of the ski. The handlebars telescopically adjust in height so when retracted to a short length they reach vertically from approximately the knee to the mid-thigh of the skier so he/she can use this ski steering device in a tucked-in position; when extended, these handlebars are easily and manually detachable from the skis and instantly become a full length ski pole adjustable to the skier's height and comfort. Various locking devices to readily lock/unlock these handlebars to the skis are described.

Abstract: This sporting, mechanical, paired, ski-steering device consists of a pair of upright curved, sturdy, handlebars attached straight up to the center of a snow ski (one per ski) in the area where standard ski bindings are mounted. The skier stands in the rear of the skis, one foot on each ski and with each foot maintained in position by a toe hold, and bends over or "tucks-in" grabbing with his/her hands these handlebars to provide control and steering. The handlebars can be directly attached to the center of the ski, but as a more convenient and versatile advantage, can also be locked on the ski by the ordinary ski bindings via a special sole that is sized and shaped at its two ends identical to the sole of the user's ski boots sole.

Abstract: A sporting, skiing, paired device to support the skier in the kneeling position, device that provides a ski and an embracing support for the kneeling knee holding the lower part of the thigh and at least part of the upper calf, skiing device that allows the kneeling rider to lean forward by providing, at the front of the ski a handle that distributes forward the weight bearing area and increases the aerodynamics of the rider. Different forms of handles are described, along with built-in-one block, or detachable-from-the-ski embracing knee supports.

Abstract: A ski steering apparatus (10) including a handlebar (11), a column (13) and telescoping member (15), fork (18) and pivotable and rotatable connector (20, 40) to each of a pair of skis (100) is described. The apparatus allows the skier to steer the skis by rotating the handle about the longitudinal axis of the support means. The connector preferably also allows the apparatus (10) to be positioned in front of the tips of the skis so that a trainer in front of the skier can guide the skier down a hill.

Abstract: An apparatus for attachment to skis to assist the user to learn basic maneuvers. A bracket is pivotally connected between the front ends of the skis in such a manner that the rear ends thereof can move inwardly and outwardly, and the skis can pivot about their longitudinal axes.

An optical seating frame is provided to fit about the motor and drive mechanism.

Abstract: A novel ski-mounting stabilizer for the sole purpose of holding a snow ski in a stationary position relative to the snow surface, and to provide a proper lateral alignment between the ski-binding mechanism and the ski boot, until the ski mounting operation is completed, and including a rigid receptacle which is attached to the upper side of a snow ski to receive the lower ends of a conventional ski pole, in the establishment of a rigid engagement between a ski and ski pole, for the sole purpose of holding the ski in a stationary position relative to the snow surface, and to provide a proper alignment between the ski-binding mechanism and the under side of the ski-boot until the ski mounting and step-in operation is completed. Wherein, immediately upon completion of the mounting and step-in operation, the ski-pole is removed from its receptacle, to be used in its conventional intended fashion while skiing.
