The object of the present invention is to provide a new type of skate in which the above-mentioned drawbacks have been eliminated.

The skate according to the invention is characterized in that the angles between the vertical sides of the slide rail and the undersides of the auxiliary slide rails are about 60 °.

Experiments have shown that the use of the skate according to the invention reduces the strain on the ankle.

This is due to the fact that when the skate is tilted, the compressive force between the skate blade and the ice surface is transferred to the sliding rail 1 le, i.e. more under the skate, so that the ankle does not have to be stressed as much as with conventional single-blade skates.

A preferred embodiment of the invention is characterized in that the slide rail, the auxiliary slide rail and the ice surface form an equilateral triangle in cross section when the rails are pressed against the ice surface. When the skate is tilted more than 30 ° as in Kick, curve and stop, the blade bites well because only the auxiliary slide rail touches the ice.

Another embodiment of the invention is characterized in that the tip of the acute angle between the slide rail and the auxiliary slide rail is rounded. In this way, no ice is packed between the rails, but due to the rounding it slides in the groove between the rails and comes off easily.

The invention will now be described by way of example with reference to the accompanying drawing, in which

Fig. 1 shows a skate according to the invention.

Fig. 2 shows an end view of the skate blade.

Fig. 3 shows the blade of the skate tilted on the ice surface.

The blade 1 of the skate consists of a sliding rail 2 with a double sliding surface, which has auxiliary sliding rails 3 on both sides parallel to the sliding rail. The sliding surfaces of the auxiliary sliding rails 3 are located above the sliding surface of the sliding rail 2. The angles between the slide rail 2 and the auxiliary slide rails 3 are about 60 °. Between the slide rail 2, the auxiliary slide rail 3 and the ice surface 4, there is a second groove 5 of triangular cross-section, which is almost equilateral when the slider is tilted. about 30 ° so that the sliding surface of the auxiliary slide rail 3 contacts the ice surface 4. The tip 6 of the sharp angle j between the slide rail 2 and the auxiliary slide rail 3 is rounded. j 3 61627

Skating with the skate shown above reduces ankle glazing. This bites well into the ice in Kick, Bend and Stop. Curve skating also becomes easier and acceleration is improved.

It will be apparent to those skilled in the art that various embodiments of the invention may vary within the scope of the claims set forth below.
