Abstract:
The presently disclosed subject matter is directed to a pair of skis that exhibit increased speed compared to prior art skis. Specifically, each ski exhibits a reduced projected frontal area to decrease drag force (and thereby increase speed). Each ski includes a plurality of parallel air tunnels that run along the length of the ski from the front end to the rear end. The tunnels enable a significant portion of the air that contacts the front end of the skis to simply pass through the skis. In this way, the projected frontal area of the skis is considerably reduced compared to conventional solid skis. As a result, the ski exhibits increased speed based on the decrease in drag force compared to prior art skis.
Abstract:
A ski collapsible for transportation comprises only two structural portions, that is the front and the rear of the ski, coupled together by provisions of a formed in the rear portion of the ski along the entire width of the opening thereof from the edge to the edge tenon corresponding to a mortise formed on an entire width of the opening of the front portion of the ski. A coupling of the ski is positioned in the location enabling attachment of the front of the binding onto the rear portion of the ski, whereas facing the rear of the ski arms of the coupling resembling a shape of a letter omega are coupled together by a transversal bar attached by screws to the arms of the coupling. The bar is located close in front of the front part of the binding, whereas a located in a long axis of the ski and shifted towards the front portion of the ski latch/clamp securing both portions of the ski against moving apart and thus separation. To the bar is adjacent a front of a plate for the front of the binding, at the opposite end thereof are located openings for screws attaching the front of the binding to the rear portion of the ski.
Abstract:
Combination ski-snowboard devices reversibly configured in both: a ski configuration comprising two skis each with both an inside and outside edge and a ski binding mounting systems, and in a snowboard configuration having two outside edges and two binding mounting systems. Methods for converting ski-snowboard devices from a snowboard configuration to a ski configuration and from a ski configuration to a snowboard configuration.
Abstract:
The present invention pertains to a device for moving over the snow, which has a backward sliding-preventing means to prevent backward sliding so as to move on flat land or uphill. More specifically, the device for moving over the snow is provided with a backward sliding-preventing means, wherein the degree of friction of a protruded member which is protruded to the bottom surface of a movement plate may be controlled by a fixed case which is selectively rotated by a user. Therefore, the protruded member serves as a stopper to prevent backward sliding by the friction with respect to the ground surface, so that forward movement may be carried out without backward sliding when moving over the snow on flat land or uphill. Accordingly, the repeating steps of detaching and reattaching of the device for moving over the snow may be removed.
Abstract:
Described herein is a sports board for gliding over a surface. The board includes an upper structural layer having an outer surface, a lower structural layer, a core having an upper surface substantially covered by the upper structural layer and a lower surface substantially covered by the lower structural layer. The board also includes a deformable element covered by the core on an upper surface. A first portion of the deformable element protrudes a distance beneath the lower structural layer towards a horizontal plane of the surface underlying the sports board. The board also includes a base element substantially covering the lower structural layer and the deformable element and an edge component positioned at least in part around a perimeter of the base element. At least a portion of the deformable element can deform upon application of an amount of pressure against the base element.
