Description

[Detailed description of the invention] [Technical field of invention] The present invention is directed to articulated skis.

The technical field of the invention is that of equipment for performing snow skiing.

[Background of the invention]

So-called "conno-ect" skis, which are easier to use and transport than conventional skis, yet allow new movements or movements that are completely different from those that can be performed with conventional skis, are already known. There is.

Monoskis (single skis), which are larger than traditional skis or compact skis and use a single board, are also known, but they can only be used by experienced skiers. There is.

The origin of the ski according to the invention was - the development of so-called "easy-to-move" skis, the difficulty of skiing on monoskis for unskilled people, and the recognition of the uselessness of the outer edges of conventional skis. That's true.

[Summary of the invention]

The objective of the invention is to create a ski based on a new concept that is easy to use, inexpensive and accessible to everyone.

This purpose, according to the invention, consists of two parallel plates, placed in the same plane, which are fitted with metal fittings fixed to the plates so that they can be displaced according to the movements of the skier. This is achieved by means of articulated skis, which are characterized in that they are connected to each other by means of articulated rods. The rod includes elastic means for placing or tending to place the ski in the plane during the skier's movements.

Said rod extends in the same plane parallel or substantially parallel to the plane of the plate, and is provided with a compression spring or a calibrating means for adjusting the flexibility of the connection at both its ends and said fitting. It has a mass of elastic synthetic material.

The metal fitting has a T-shaped cross section and is attached to the top of the plate.

It has a bottom plate fixed to said plate perpendicular to the corner-extending web and its bottom plate. Rods also pass across these webs.

In one embodiment, the connecting rods are connected to the fittings, and these fittings are removably mounted in a plate fixed to the plate;
Clamping means allow it to be held together with or removed from the board. The bottom plate of each metal fitting is placed in a rectangular storage part provided in each of the bottom plates, and the storage part has a height approximately equal to the thickness of the bottom plate, and the storage part is placed on the sides and top of the bottom plate. The base plate has a projecting end projecting above the projecting end, and is movable to restrain the base plate together with the lamp in a plane facing the projecting end. The clamp is also urged into the flange position by spring means.

The clamp has an extension at the end opposite to the end that holds the bottom plate of the I-Q tool in one leg position, in which a hole is provided to facilitate operation of the clamp. It is being

The fixing plate of said coupling part has, on its center line and at a distance from the upper clamp of the clamp, an extension extending from the side of the hole in the clamp, the end thereof being substantially perpendicular to the center of the hole. It has a notch carved into it. Open the clamp and, at p>*, place the rod used as a lever in this extension and pass the lower end of the rod into the hole.

The bottom plate of the fitting has an angular profile and is housed in an angular recess that allows it to be placed in the longitudinal direction of the plates when the connection part is rotated 90° to separate the two plates. It has become.

The board is provided with an edge along the edge of the inner part 11j like a conventional ski, but according to the present invention, the inner part τ11 of the board is provided with an edge.
The hem is floating and connected to the spatula-shaped parts at the front and back ends.

As a result of the invention, the two plates are connected to each other by a connecting port with adjustable elastic means, said adjustable elastic means keeping the two plates parallel to the ground. This results in a pair of skis with a new concept that has the ability to return to a 211 tral position in the same plane.

Since the connection is removably attached, the two boards can also be used independently of each other, like in conventional skis.

The connection can also be attached to conventional skis equipped with quick attachment hardware according to the invention.

The ski according to the invention has no outer skims or ridges, has a spatula-like part at the front and back, and is composed of two plates connected to each other at a joint, forming a kind of monoski as a whole. However, it can be operated more freely than the conventionally known monoski, and it is also easier to use. The movement of the joint is restricted by a spring or mass of elastic material, which can be adjusted so that the two plates have limited independence.

Two boards with edges on the inside edges are connected and spaced from each other to facilitate movement and snow removal.

In embodiments where the coupling is removable, the coupling is secured to the plate by means of a quick-fit fitting that can be easily unclamped, for example at the end of a ski, pole or tuck.

As a result of this connection and quick attachment concept, the skier can also remove the connection or attach it in a vertical position on either board to create an independent pair of skis.

The combination of the ski's front and rear spatula and raised edge allows the skier to perform one or more rotations around an axis on the W, Ire extending from the skier's head to the foot. can move freely. This concept also facilitates landing on the snow when turning.

The ski according to the invention is used in the horizontal skiing technique called "Wedeln" and the relative independence of the boards makes skiing easier to practice and reduces the risk of falls.

Since the plates are articulated with each other in an elastic manner, it is possible to use a variety of materials for the manufacture of the plates, thus reducing the cost of the ski. Skis can be disassembled, making them easy to transport and organize.
