Abstract

An interchangeable ice skate blade for use with a roller skate boot of the inline skate type includes a plurality of elongate bores or slots and a single circular bore or slot of a comparable size in the region of the edge of the blade remote from the ice-engaging edge. The combination of elongate and circular bores or slots allows the blade to be compatible with roller skate boots having different points of attachment of the blade to the boot while securely retaining the blade against unintended lengthwise or transverse movement relative to the boot.

Claims

1. An ice skate blade for a roller skate of the incline skate type having an elongate carrier with at least four transversely extending openings spaced apart lengthwise thereof for receiving corresponding ones of at least four transversely extending axles for rotatable mounting on the carrier at least four roller skate wheels, the improvement in said ice skate blade comprising:

said ice skate blade having a front end and a rear end and a lengthwise extent there between, said blade further having a first front-to-rear extending edge forming an ice-contacting blade edge, a second front-to-rear extending edge spaced from said first edge, and substantially parallel first and second sides extending between said first and second edges;

said ice skate blade having extending transversely there through from said first side to said second side (a) a substantially-circular opening (b) first and second substantially-elongate openings located between said substantially-circular opening and one of said front and rear ends, and (c) a third substantially-circular opening located between said substantially-circular opening and the other of said front and said rear ends;

all of said openings being located adjacent said second edge and aligned lengthwise of said blade along a line substantially parallel to said first edge;

said elongate openings being elongated in the lengthwise direction of said blade; and

the elongate extent of said elongate openings increasing with increasing distance of said elongate openings from said substantially circular opening;

whereby, upon alignment of said substantially circular opening with the transverse axle opening in the carrier that is located second in line from an end of the carrier, said elongate openings in said blade align with respective ones of the other transverse axle openings in the carrier.

2. An ice skate blade as set forth in claim 1, said blade further comprising a fixing element for fixing the blade to the carrier, said fixing element extending over substantially the entire length of the blade along said first side thereof.

3. An ice skate blade as set forth in claim 2, further comprising a second fixing element, said second fixing element bearing against the ice skate blade on said second side.

4. An ice skate blade as set forth in claim 1, wherein said second edge has notches cut out between said openings, whereby the weight of the blade is reduced.

5. An ice skate blade for a roller skate of the incline skate type having an elongate carrier with at least four transversely extending openings spaced apart lengthwise thereof for receiving corresponding ones of at least four transversely extending axles for rotatably mounting on the carrier at least four roller skate wheels, said ice skate blade comprising:

said ice skate blade having a front end and a rear end and a lengthwise extent there between, said blade further having a first front-to-rear extending edge forming an ice-contacting blade edge, a second front-to-rear extending edge spaced from said first edge, and substantially parallel first and second sides extending between said first and second edges;

said ice skate blade having extending transversely there through from said first side to said second side (a) a substantially-arcuate attachment notch, (b) first and second substantially-elongate attachment notches located between said substantially-arcuate attachment notch and one of said front and rear ends and (c) a third substantially-elongate attachment notch located between said substantially-arcuate notch and the other of said front and said rear ends;

all of said notches being cut into said second edge and aligned lengthwise of said blade along a line substantially parallel to said first edge;

said substantially-elongate notches being elongated in the lengthwise direction of said blade; and

the elongate extent of said substantially-elongate notches increasing with increasing distance of said substantially-elongate notches from said substantially-arcuate notch;

whereby, upon alignment of said substantially-arcuate notch with the transverse axle opening in the carrier that is located second in line from an end of the carrier, said substantially-elongate notches in said blade align with respective ones of the other transverse axle openings in the carrier.

6. An ice skate blade as set forth in claim 5, further comprising a first fixing element for fixing the blade to the carrier, said first fixing element extending over substantially the entire length of the blade along said first side thereof.

7. An ice skate blade as set forth in claim 6, further comprising a second fixing element, said second fixing element bearing against the ice skate blade on a side opposite the first side of the blade.

8. An ice skate blade as set forth in claim 5, wherein said second edge has notches cut out between said attachment notches, whereby the weight of the blade is reduced.
