Skate with cut guard

Abstract

The present invention relates to a skate with a cutting guard which protect people from the sharp lower part of the skate blade when the skate is in the air above the surface, but moves up so that the skate blade exposes when the skate makes contact with the surface. The invention is to reduce the risk of cutting yourself or others on the skate's sharp blade.

Description

This invention provides a skate with a cut guard that protect people from the sharp lower part of the skate blade when the skate is in the air.

BACKGROUND OF THE INVENTION

When performing sports with skates such as ice hockey, short track and bandy, there is a risk of cutting yourself or others on the skate's sharp blade. This has led to serious injuries and even deaths. On the market today, there are various protections to avoid cuts such as neck protection, wrist protection, underwear and socks with sewn-in cut protection. The problem with these protections is that they don't provide full coverage and can be perceived as disturbing and clumsy to wear.

The Chinese patent CN109529308A has tried to solve the problem with cut guards on each side of the skate blade as well as detectors on the skater's body that will detect when the skater falls and then fold down the guards to cover the cut. This is a considerably more complicated system and differs significantly from the fully mechanical solution of the present invention. Another major problem with the technology in patent CN109529308A is that after each time the skater falls, the skate must be reset before it can be skated again. This makes it impossible to use that solution in sports such as ice hockey and bandy where you have to be able to get up quickly after a fall and continue playing.

SUMMARY OF THE INVENTION

The invention solves the problem through a cut guard on the skate itself that cover the sharp lower part of the skate blade (the edge) when the skate is in the air above the surface, but are pushed up when the skate is in contact with the surface. This is done by the cut guard having two pins, one in front and one behind the skate blade. When the pins make contact with the surface they are pushed in. This allows the cut guard to slide up and the skate blade makes contact with the surface. When you lift the skates, the cut guard springs back down and covers the edge of the skate blade. If the pins are not pushed in, the cut guard cannot slide up and the sharp lower part of the skate blade remains protected. This does not completely remove the risk of cuts as there is a risk that in a situation you could hit one of the pins which allows the cut guard to go up and at the same time also hits the skate blade on which you cut yourself. However, the risk of cuts is dramatically reduced, instead of risking cutting yourself on the entire blade, you now have to hit a pin of a few millimetres and then the skate blade to risk cutting yourself.

DETAILED DESCRIPTION OF THE INVENTION

The invention consists of a blade holder (1) that holds the skate blade and a cut guard (2), FIG. 1. The cut guard (2) runs along the skate blade, on both sides of it. When the cut guard (2) is in its extended position, it covers the edge of the skate blade in such way that possibility of cutting is prevented. In the front and back of the blade holder (1), FIG. 2, there are two cut guard holders in which the ends of the cut guard (2) are inserted. The cut guard holders comprise an elastic object, which in the drawings is represented by a spring (3). A spacer (4) holds the elastic object in place. The elastic object provides the cut guard (2) with a bias toward its extended position. This causes the cut guard (2) to spring back to its extended position when the skate is lifted off the surface. The cut guard (2) is visualized in FIG. 3 and cross sections of the cut guard ends are shown in FIGS. 4 and 5. Each end comprises a pin (6), with a cut out in it, and a ball (7). The pin (6) is biased towards its outer position by an elastic object. In drawings the elastic object is represented by a spring (5). When the pin (6) is in the outer position, as in FIG. 4, the ball (7) protrudes from the cut guard ends. When the pin (6) is in the inner position, as in FIG. 5, the ball (7) allows to travel into to the end of the cut guard (2) and into the cut out of the pin (6). When the skate is in the air, shown in FIG. 6, the pin (6) is in its outer position and the ball (7) protrudes from the cut guard end into a cut out in the blade holder (1). This prevents the cut guard (2) from being able to slide up into the blade holder (1). The cut guard (2) is locked in its extended position. When the pin (6) make contact with the surface, shown in FIG. 7, the bias for the pin is exceeded and the pin (6) is pushed to its inner position. The ball (7) moves in to the cut guard end and the cut guard (2) can move from its extended position. The edge of the skate blade will be exposed.

Claims

1. A blade holder (1) for a skate included: a skate blade;a front cut guard holder;a rear cut guard holder;a cut guard (2) arranged along the skate blade on both sides thereof, which cut guard (2) include a front and a rear end, which are movably arranged in the front and rear cut guard holder so that the cut guard (2) is movable between an extended position, in which it covers the lower sharp part of the skate blade, and retracted positions in which the lower sharp part for blade is exposed, wherein the cutting guard (2) comprises a front pin (6) which is movably arranged in the front end between an outer and an inner position, and a rear pin which is movably arranged in the rear end between an outer and an inner position, wherebythe cut guard (2) is biased towards the extended position and each of the pins (6) is biased towards the outer position, wherebywhen each of the pins (6) is in its outer position, the cut guard (2) is prevented from moving from the extended position, andwhen each of the pins (6) is in its inner position, the cut guard (2) is allowed to move between the extended and retracted positions in which the lower sharp part for blade is exposed,wherein the bias of the pins (6) is such that it is exceeded when the pins (6) are in contact with a surface whereby the pins move from their outer position to their inner position, thereby allowing the skate blade to come into contact with the surface.

2. Blade holder (1) according to claim 1, whereby the front cut guard holder includes a front cut out, andthe cut guard (2) includes a front ball (7) movably arranged in the front end,whereby when the front pin (6) is in the outer position, the front ball (7) is arranged to move into the front cut out and thereby locking the front end relative to the front holder, and when the front pin (6) is in the inner position allowing the front ball (7) to move out of the front cut out and thus allowing the front end to move relative to the front cut guard holder,andthe rear cut guard holder includes a rear cut out, andthe cut guard (2) includes a rear ball (7) movably arranged in the rear end,whereby when the rear pin (6) is in the outer position, the rear ball (7) is arranged to move into the rear cut out and thereby locking the rear end relative to the rear cut guard holder, and when the rear pin (6) being in the inner position, the rear ball (7) is allowed to move out of the rear cut out, thereby allowing the rear end to move relative to the rear cut guard holder.
