Abstract

ABSTRACT OF THE DISCLOSURE:

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 and of which the gliding surfaces are located higher than the gliding surface of the gliding rail. The angles between the gliding rail and the auxiliary gliding rails are about 60°.

Description

.2 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 ob~ect of this invention is to provide a new type of skate which isconsiderably 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 60 . 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 i6 a groove with triangular shape and which is isosceles or nearly equilateral when the skate has been inclined 30 so that the gliding surface of the auxiliary gliding rail touches the ice surface.
When the skate ls lnclined more than 30 , 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, .

i66~2 with reference belng made to the attached drawing, wherein:-Fig. 1 presents a skate as taught by the lnventlon.

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 surfacesand 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 60 . Between the gliding rail 2, the auxiliary gliding rail 3 and the ice surface 4 there is a groove 5 of triangular cross sectlonal shape and which is nearly equilateral when the skate i8 inclined about 30 80 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 pu6hes, curves and at stop-ping. Skating through curves i9 also facilitated and the accelerating capaclty lmproves.

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

Claims

The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows.

1. A skate including a shoe having a sole and a blade assembly fixed to said sole, said blade assembly comprising: a central gliding rail and, on either side thereof, an auxiliary gliding rail shorter than said central gliding rail, said rails having gliding edges, the improvement wherein each of said auxiliary gliding rails makes an angle of about 60° with said central gliding rail.

2. A skate according to claim 1 wherein, in use when said skate is inclined at an angle of about 30°
with respect to the vertical, the gliding edge of the auxiliary gliding rail located between said central gliding rail and a skating surface on which said skate bears, touches said skating surface.

3. A skate according to claim 1, wherein said auxiliary gliding rails define with said central gliding rail and planes extending between the gliding edges of said rails, isosceles triangles.

4. A skate as claimed in claim 1, wherein said auxiliary gliding rails define with said central gliding rail and planes extending between the gliding edges of said rails, equilateral triangles.

5. A skate as claimed in claims 3 or 4, wherein said triangles each has a rounded apex between said auxiliary and central guiding rails.
