Abstract

The invention consist of a tool-less system applied for adjusting the wrist-strap and the toe-strap on snowboard bindings, where such tool-less system is made up with the combination of 3 elements, 1. It is tool-less so the attachment position of the binding strap can be unlocked from one position on the binding frame and locked into another position fairly easily with bare hands 2. It has a stable locking mechanism based on a profiled press-button / pin element fitting into at least one hole with profiled shape provided in the frame of the binding where also at least one hole provided in the strap(s) will fit in and be securely locked in when the button element is put in place 3. The press-button element is put in place from the inside and prevented from popping out during use also by the boot which blocks the only exit direction for the button element, which is inwards. The wrist-strap will further be prevented from popping out by the highback, which during riding covers the button element holding the wrist-strap in place. The toe-strap may further be prevented from popping out by the base-plate.

Abstract

A ski for mounting a binding on the ski's surface approximately in the middle of the ski or slightly behind the middle, where the ski is provided with inwardly curved edge portions, the ski having greater width at the transition to the front tip than in the middle, and the ski has an upwardly curved front tip. The ski combines features from skis with a very special and characteristic three-dimensional geometry in the actual sliding surface, and a special design of the tip (possibly also in a rear tip where this is relevant), where the tip's secondary sole surfaces (3, 4) are twisted upwards relative to a central reference surface (1, 2), with the result that the ski's tip succeeds in pressing more snow under the ski when running in loose snow and slush, and the invention thereby provides a ski which both glides better in loose snow as well as retaining all the favourable dynamic properties which exist in the described three-dimensional design of the actual sliding surface on the ski.

Abstract

The present invention is based on known types of bindings, where it is provided a binding (1) which can be used without a detachable calf support (6) while retaining the ability of the binding (1) to position the boot correctly in the binding (1). The fundamental principle is that one makes a detachable calf support (6) which can easily be removed and adjusted, whereupon the binding (1) will still be able to position the boot correctly in the binding (1) without being adjusted forwards or backwards in any direction on the snowboard. The device preferably permits the detachable calf support (6) to be removed and replaced again without the use of tools. The invention also offers the opportunity of using different intermediate types of calf support (6).

Abstract

The invention relates to a roller ski which is employed amongst other things for training in classic cross-country skiing during the summer. The object of this roller ski is to achieve a pressure-dependent grip when a kick is generated, with the result that more pressure on the ski from the foot provides better grip. This is in order to simulate skiing on snow, where in classic style pressure has to be placed on the ski during the kick in order to obtain grip on the middle of the ski. The invention is based on a common principle. Roller systems with free roll both forwards and backwards are combined with roller systems with one-way roll, in such a manner that when the pressure on the roller ski from the skier increases, the roller system(s) with one-way roll will be activated to an increasing extent as the pressure on the ski increases, with the result that the ski obtains grip thereby enabling a kick to be generated. The grip is obtained without any risk of the ski jerking in the event of unexpected pressure from a rough surface. Without extra pressure the roller ski will be liable to back-sliding just like a classic cross-country ski with grip wax under the middle and glide wax at the front and rear.

Abstract

The present invention is based on the combination of a snowboard with a 3- dimensional sole which wholly or partly has a tripartite sliding surface in the portion between the transition to the tip(s) and the binding fastening(s), in addition to which the board is equipped with an additional special 3 -dimensional geometry in the tip(s), in order to continue the existing uplift in the lateral sliding surface (5), thereby ensuring better uplift and thus better glide and greater speed in loose snow, a combination which provides quite unique riding characteristics. The tip of the snowboard is designed in such a manner that it presses the snow under the board more efficiently, lifting it further up from the snow than an ordinary tip. When riding straight ahead, this is best accomplished by using what is called here a skate plate, with an almost straight portion in the tip, providing an extended tip at a moderate angle to the surface and thereby extremely careful treatment of the snow while keeping the tip above the snow. When turning, an improved uplift in the tip is achieved by successively increasing the angle between the central sole surface (2) and the lateral sole surface (6) in the tip from the end of the sliding surface a few cm forwards in the tip, with the result that during edging the lateral sole surface lies substantially flatter against the snow further forward in the tip than at the transition to the tip, thereby more efficiently pressing the snow under the snowboard and not to the side, thus causing the board to also glide better during turning. Skate plate (3) is only used where the board is to be used principally on rails and boxes in parks, and good riding characteristics also require to be retained during normal riding on the ground. Thus the solution is to integrate a plateau (3) between the ordinary sliding surface (1) and a somewhat more modest front tip (4) on the board, the point being that when riding on snow this plateau (3) should function as a part of the nose, while during active use of the plateau on rails and boxes it has a separate function as contact surface against the surface when on other snowboards the trick in question normally involves the use of the front part of the sliding surface (1). This concept can best be employed with a certain degree of regular camber between E-E and V-V. However, it may also be envisaged used in combination with boards without camber, or even reverse camber in this area. The characteristics will be further improved by exploiting the concept of a tripartite sliding surface, with the result that the steel edges are already raised on the inside of the tip(s), thereby ensuring a gentler rate of increase in the lateral sole surfaces (6) in the tip(s) and enabling the tip to glide with less resistance, particularly during turning.

Abstract

The tips are upwardly curved and the board's/ski's underside (the sole) is provided with first and second surfaces, straight in cross section, extending in the board's/ski's longitudinal direction, which are arranged at an angle to each other and usually interconnected via a third surface. The sole's first and second sole surfaces (2) at the lateral edge, which normally consists of a steel edge, have a varying height over a third sole surface (1), where this height typically both increases and decreases as one advances from the middle of the snowboard/ski towards the transition to the tip (A-A). At the same time the first and second sole surfaces (2) at the lateral edge substantially have a greater height over the third surface (1) in a 10 cm long area from the transition (A-A) and backwards than in the area forming the central half of the snowboard/ ski.
