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.

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, whereby the cut guard (2) is biased towards the extended position and each of the pins (6) is biased towards the outer position, whereby when each of the pins (6) is in its outer position, the cut guard (2) is prevented from moving from the extended position, and when 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, and the 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, and the rear cut guard holder includes a rear cut out, and the 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.

DETAILED DESCRIPTION OF THE INVENTION

[0012] 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.
