Abstract: A ski tip connecting device has a flexible connector connecting a first lever clamp to a second lever clamp. The first lever clamp holds the ski tip of a first ski. The second lever clamp holds the ski tip of a second ski. The flexible connector maintains a short distance between the ski tips allowing the ski tails to separate to a wider distance with the skis forming a snowplow position.

Abstract: Disclosed is a device to connect the tips of skis and thereby enable a skier to create, hold, and adjust the shape of a wedge with his skis. The device is comprised of two sleeves which slip over and are secured to the upturned tips of the skis. The sleeves are connected by a length of flexible, stretchable, or both, material. This connection is either fixed or made by a novel easily detachable hook. The device allows the skis to be easily connected or disconnected for lift rides, when walking across flat terrain, or to evaluate the progress of the skier during a lesson. As a result, disclosed is a novel device which enables a skier to make, hold, and adjust a wedge while being easily detached for normal skiing and easily used by a skier or instructor wearing gloves or mittens.

Abstract: A binding for a boot includes a platen (4) which is manually mountable to a snowboard in a selected angular position. The platen includes a central hole (4a) and a circular array of upwardly facing teeth (4c). A base (9), mounted to the snowboard, has a spindle (16) and locking arms (16a, 16?a) which extend through the platen central hole. A central pivot body (5) includes a circular peripheral surface (5a) and downwardly projecting teeth (5b) which interact with the central hole and teeth of the platen. Ramping cam elements (8d, 8?d) on a locking disk engage the locking arms and progressively clamp the pivot body to progressively press the teeth of the pivot body against the teeth of the platen to prevent rotation. A clamp (22) having cam ends (22a, 22?a) is pivotal between a vertical release position which permits the central locking disk to rotate and a flat position which locks the central locking disk against rotation.

Abstract: An articulated snowboard includes first and second members that are joined at a first end by an articulation mechanism that permits vertical offset between the members while preserving parallel orientation of at least one of a longitudinal axis through each member and a leading edge of each member. Articulation enhances stability, user control, and braking action. Further, the articulation mechanism permits folding the articulated snowboard in half for storage and transport, and also permits separating the two members. When separated the two members can be worn by a user as emergency snowshoes or short skis.

Abstract: A snowboard-type ski system and apparatus utilizing two skis and rotary linkage to provide the skier with the natural feel of snowboarding and the response and control of two skis. The system coordinates and maintains parallel alignment, vertical motion, and consistent horizontal separation of the two skis through the use of two linkage cranks which rotate about an axis transverse to the direction of travel intended for the two skis. The linkage includes an elevated mounting assembly positioned between the two skis and above the snow upon which a skier may mount bindings. The points of attachment and rotation are between the skier's feet such that the point of attachment to the two skis is proximate to the ski manufacturer's intended loading point. The transverse rotary motion permits the two skis to cant with respect to one another, as the skier enjoys rough terrain, and maintains' natural motion and transfer of force between the two skis.

Abstract: Ski apparatus with two outer skis and a third ski, located between the two outer skis, coupled to the outer skis by four cranks, connected as a front pair and a rear pair. Each crank has a gear on one end and a free end. The free end of a crank is attached to a journal box on an outer ski to permit the crank to rotate freely. The gear of the crank from one outer ski meshes with the gear of a crank attached to the other outer ski, coupling the cranks in pairs and causing the cranks to rotate in opposite directions. The gears from each pair are contained in a gearbox attached to the third or middle ski. In one embodiment, the journal box may be slidably attached to the ski, to permit the ski to move forward and backward relative to the journal box, thereby permitting the user to alternately advance and retreat the skis relative to each other.

Abstract: A ski stabilizing device used in combination with a pair of skis to assist a novice skier in learning to ski includes a pair of block members, each block member attached to the inner edge of one ski adjacent the inflected tip of the ski. Each block member encases a spherical region which registers with a circular aperture located on an inside face of the respective block member. Disposed within each spherical region is a ball. Extending between the block members for connecting each ball is a connecting rod which maintains the skis at a generally fixed distance from each other. The encasement of the balls within the block members allows for the independent angular, rotational and longitudinal movement of the skis with respect to each other and with respect to the ski slope on which the novice skier is skiing. The device includes the capability to gradually enlarge or reduce the amount of angular, rotational, and longitudinal movement of the skis.

Abstract: Ski apparatus two outer skis coupled to a third ski, located between the two outer skis, by four cranks, connected as a front pair and a rear pair. Each crank has a gear on one end and a free end. The free end of a crank is attached to a journal box on an outer ski to permit the crank to rotate freely. The gear of the crank from one outer ski meshes with the gear of a crank attached to the other outer ski, coupling the cranks in pairs and causing the cranks to rotate in opposite directions. The gears from each pair are contained in a gearbox attached to the third or middle ski. The cranks can be stiff or resilient and, if resilient, includes an elbow joint which is spring biased to force the middle ski below the outer skis.

Abstract: The accessory for skis, intended to link two skis together in order to facilitate their guidance, comprises a connecting leaf or strip (1) mounted on resiliently flexible members (3) rigidly fixed to the tips of the skis and making it possible to vary the relative position of said skis.

Abstract: A ski attachment for protecting the upper surface of a rear portion of a ski is formed as a rigid body of hard impact resistant material having a base securable to the upper surface of a rear surface of a ski. The body is generally triangular in side view with a substantially flat rear face extending upwardly and forwardly from a rear base edge at an angle in the range of from about 35.degree. to about 50.degree. to the base to a vertical height above the base in the range of from about 0.375 to about 0.875 inches.

Abstract: A ski guard is formed of an elastically tiltable stirrup made of a plastics material with a holding member formed as a part of the stirrup. The holding member maintains the stirrup member in the upright position on a ski by securing its support surface in contact with the upper surface of a base member which attached the stirrup to a ski. When the stirrup tilts or pivots, the support surface on the holding member moves over a boundary surface on the base member overcoming a dead-center position. Movement beyond the dead-center position takes place because of the deflection of a part of the holding member spaced from the support member. Axle journals in spaced axial alignment pivotally mount the stirrup on the base member and permit the location of a large locking element between them for detachably fastening the base member on a fastening plate.

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. A vertical pole is pivotally attached to each ski at a point between the front bracket and the boot retaining means. A connecting rod is pivotally connected between the poles.

Abstract: A ski attachment is provided with a vertically directed slot-like opening bounded by two parts which project upwards from its base plate. As the ski attachment can be fixed to a ski in easily detachable manner, it can serve in the detached state as a clip for holding together a pair of skis by introducing the skis into the slot-like opening. The skis of one pair then engage with one another within the attachment by their contact surfaces.

Abstract: A ski safety device for deflecting a ski leaving its direction from crossing over to the other ski, has two brackets each movable between a normal position in which it extends upright to the respective ski, and a folded position in which it folds down toward the same with resistance. The brackets pivot in the direction of travel and about an axis which is transverse to this direction.

Abstract: A ski safety device prevents unintentional crossing of skis during skiing. It has a support plate mountable on an upper surface of a ski, and a frame above the support. A bottom wall of the frame faces the upper side of the support and a layer of elastically compressible material, such as plastic foam material, is interposed between them. The bottom wall of the frame is formed with an elongated opening and the upper side of the bottom wall has at opposite sides of the opening respective depressions which extend outwardly away from the opening. A projection extends upwardly from the support through the opening and is formed with two transverse extensions which enter into the respective depressions when the frame is turned relative to the support from a position in which the elongation of the opening is parallel to that of the extensions to another position in which the two directions of elongation are inclined relative to one another, under simultaneous compression of the elastically compressible material.
