Abstract

Un patin consiste en une chaussure et une lame (1) fixee a sa semelle, cette lame etant constituee par un rail de glissement (2) de chaque cote duquel se trouvent des rails de glissement et dont les surfaces de glissement sont situees a un niveau superieur a la surface de glissement du rail de glissement. Les angles entre le rail de glissement (2) et les rails auxiliaires de glissement (3) sont de 60 environ.A skate consists of a shoe and a blade (1) fixed to its sole, this blade being constituted by a sliding rail (2) on each side of which there are sliding rails and whose sliding surfaces are located at a level greater than the sliding surface of the sliding rail. The angles between the sliding rail (2) and the auxiliary sliding rails (3) are approximately 60.

Description

Skate

The present invention concerns a skate consisting of a shoe and a blade affixed to the sole thereof, said blade consisting of a gliding rail, on both sides of which there are auxiliary gliding rails parallel to the gliding rail, their gliding surfaces being located higher than the gliding surface of the gliding rail.

There are various types and shapes of auxiliary gliding rails mounted on the sides of the gliding rail of a skate blade. In practice, drawbacks have been observed in the operation of such a skate, and therefore no development and no marketing thereof has taken place.

The object of this invention is to provide a new type of skate which is considerably superior in firmness to skates known in the art, especially in turns, pushes and stopping. The skate.of the invention is characterized in that the angles enclosed between the gliding rail and the auxiliary gliding rails are about 60º. By the invention the stress imposed on the skater's ankle is reduced. The auxiliary gliding rails lend additional rigidity to the blade, whereby a puck hitting the side of the blade cannot break it in two, as has happened. The blade can be made lower than before without risking that the side of the skating shoe may touch the ice in curve skating for instance.

An advantageous embodiment of the invention is characterized in that between the gliding rail, the auxiliary gliding rail and the ice surface there is a groove with triangular shape and which is isosceles or nearly equilateral when the skate has been inclined 30º so that the gliding surface of the auxiliary gliding rail touches the ice surface. When the skate is inclined more than 30º, as happens in a push, curve or in stopping, the blade, will bite well because only the auxiliary gliding rail touches the ice.

Another embodiment of the invention is characterized in that the point of the acute angle between the gliding rail and the auxiliary gliding rail has been rounded. As a result, no ice will be packed between the gliding surfaces: owing to the rounding it will slide in the groove between the rails and come off easily.

The invention is described in the following with the aid of an example, with reference being made to the attached drawing, wherein:-

Fig. 1 presents a skate as taught by the invention.

Fig. 2 shows the blade of the skate, in end view.

Fig. 3 shows the skate blade on the ice, in inclined position.

The skate blade 1 consists of a gliding rail 2 with two gliding surfaces and having on either side auxiliary gliding rails 3 parallelling the gliding rail. The gliding surfaces of the auxiliary gliding rails 3 are located higher than the gliding surface of the gliding rail 2. The angles enclosed between the gliding rail 2 and the auxiliary gliding rails 3 are about 60º. Between the gliding rail 2, the auxiliary gliding rail 3 and the ice surface 4 there is a groove 5 of triangular cross sectional shape and which is nearly equilateral when the skate is inclined about 30º so that the gliding surface of the auxiliary gliding rail 3 touches the ice surface 4. The point 6 of the acute angle between the gliding rail 2 and the auxiliary gliding rail 3 has been rounded.

Skating with the skate above described reduces the stress imposed on the ankle. The blade bites well into the ice in pushes, curves and at stopping. Skating through curves is also facilitated and the accelerating capacity improves.

It is obvious to a person skilled in the art that different embodiments of the invention may vary within the scope of the claims presented below.

Claims

2. Skate according to claim 1, characterized in that between the gliding rail (2), the auxiliary gliding rail (3) and the ice surface (4) is defined a groove (5) with triangular cross section and which is isosceles or nearly equilateral when the skate has been inclined about 30º so that the gliding surface of the auxiliary gliding rail (3) touches the ice surface (4).
