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 h...

Two pivoting parts (8a, 8b) each mounted on one of the skis (1, 2) forming a pair are arranged so that each of them cooperates with two retaining parts (7a, 7b) each fixed on one of the skis. When each pivoting part (8a, 8b) is fixed via its free end to the retaining part (7a, 7b) of the same ski, the skis are separate (FIG. 1), whereas when these pivoting parts (8a, 8b) are rotated through 90.degree. and are fixed via their free end to the retaining part (7a, 7b) of the other ski, the two skis ...

The linking device comprises two near-symmetrical portions, each with an attachment piece (1', 1") which can be fixed securely to the ski tip, an arm (3', 3") which is integral with the said attachment piece, and a joint (4', 4") which interconnects the forward ends of the said arms. The joint is preferably of the spherical ball-in-cup type. The device allows the skis to be positioned parallel to each other, as well as to be turned to the snowplow position, and it renders the sport very much eas...

A traction device for skis is provided. An arm having a loop is pivotally mountable on a ski immediately ahead of a ski harness. The end of the arm distal from its pivot mount has a loop adapted for engagement with the point and basket of a ski pole. A skier employs his ski poles to pivot the arms to a position on the outer side of his skis whereby the point of a ski pole serves to hold one ski stationary while the other ski is advanced.

A seawater powered band saw having a rigid frame or housing, a control handle and valve assembly having a trigger which when engaged by an operator delivers pressurized seawater to a seawater powered vane motor, a novel seawater lubricated spur and pinion gear drive arrangment connecting the vane motor in a driving relationship to a band saw drive wheel, an idler take-up assembly to tension the saw blade and facilitate the changing of saw blades and a safety guard assembly to protect the blade w...

A skiing device having at least a pair of parallel, elongated, longitudinally extending runners is provided with a platform therebetween, and quadrilateral linkage arrangements extend between the runners and the platform independently while at least one link member extends between the runners. The quadrilateral linkage arrangements between the runners and the platform allow the ski to carve a turn in the slope of a hill with more ease since the two runners present separate control edges.

Alpine ski (1) having a sidecut (9) which has a radius smaller than 24 meters, wherein the front (10) and/or rear (18) ends have a cavity (11, 15) opening longitudinally at said end, the dimensions of the cavity (11, 15) allowing the deformation of said end when a transverse force is exerted at the front and/or rear contact lines so as to permit the inner and outer edges of the ski to move closer to one another.

The invention provides a device for joining two skis together, which is readily removable with the skis on the feet, including a connection means formed by a bar of variable length, with fittings at both its ends for articulating through several degrees of freedom, themselves connected to the ski tips by fastening-unfastening fittings formed by a male part and a female part secured to the articulation fitting and the other to the ski tips. The parts are lockable-unlockable by fitting together, t...

A combination ski and binding plate apparatus comprising a first and second mounting plate assembly for supporting mounting plates for boot bindings and for operably linking a pair of skis. The first and second mounting plate assemblies each comprise a four bar linkage assembly including a first inner bar and a first outer bar operably secured to a mounting plate. The first inner bar is pivotally secured to the first outer bar. A rear linkage assembly including a rear inner bar and a rear outer ...

As an aid for a novice skier, a close fitting fabric glove confines the forward portion of a pair of water-skis. The glove both prevents excessive lateral separation of the skis and maintains a desirable minimum separation--both features greatly assisting a novice, for example, in "getting up" from a deep water start and in his stability when waterborne. The greater planing area of the glove, compared with the ski portions it covers, and its buoyancy (from air entrapment), both help the skier to...
