Abstract

The skate boot construction includes a unitary plastic heel/ankle counter insert which may be secured externally or internally to a soft boot mounted on a skate truck. The insert includes two spaced side portions joined by a U-shaped heel section which extend along the sides of a skater'"'"'s foot. Above the side portions and the heel section are two forwardly projecting side flaps joined by an arcuate back section which are connected to the spaced side portions by two outwardly bowed hinge sections positioned over a skater'"'"'s ankle bones. An arcuate slit extends through the heel/ankle counter between the heel section and arcuate back section and runs for a distance along either side of the heel/ankle counter. End slits extend transversely above and below each end of the arcuate slit. Cutaway portions below the side flaps extend inwardly toward the end slits and with the end slits define the edges of the bowed hinge sections.

Claims

1. A unitary, injection molded, in-line skate boot for receiving the foot of a wearer comprising:

a substantially U-shaped heel portion,

first and second opposed side wall portions extending longitudinally from said heel portion and a sole portion extending between said side wall portions and said heel portion to define a cavity for receiving a wearer'"'"'s foot which is supported and enclosed thereby,

a heel slit formed in the heel portion and spaced above said sole portion, said heel slit extending into said cavity and having a first end positioned in said first side wall portion and extending through said boot from said first sidewall portion across said heel portion to a second end positioned in said second side wall portion,

a boot upper extending above said heel portion, said boot upper including first and second opposed flaps extending above said first and second opposed side wall portions, said first flap including a bottom edge defined by a first flap slit extending through said boot into said cavity between said first flap and said first sidewall portion, said first flap slit angling downwardly and rearwardly of said boot from an open end above said heel slit to a first flap slit inner end spaced from the first end of said heel slit and

said second flap including a bottom edge defined by a second flap slit extending through said boot into said cavity between said second flap and said second sidewall portion, said second flap slit angling downwardly and rearwardly of said boot from an open end above said heel slit to a second flap slit inner end spaced from the second end of said heel slit,

said heel slit being configured with said first and second flap slits to define a first joinder section extending between said boot upper and said first sidewall portion having an elongate forward edge defined by said first flap slit opening into said cavity and an elongate rear edge defined by said heel slit opening into said cavity and a second joinder section extending between said boot upper and said second sidewall portion having an elongate forward edge defined by said second flap slit opening into said cavity and an elongate rear edge defined by said heel slit opening into said cavity,

each of said first and second joinder sections being bowed outwardly away from said cavity to form first and second integral hinges respectively which are the only joinders between the boot upper and said first and second sidewall portions.

2. The boot of claim 1 wherein said first end of said heel slit is positioned adjacent to said first joinder section and the second end of said heel slit is positioned adjacent to said second joinder section, a first enlarged opening is provided at the first end of said heel slit to extend through said boot into said cavity and transversely above and below said heel slit to define a rear edge of said first joinder section and a second enlarged opening is provided at the second end of said heel slit to extend through said boot into said cavity and transversely above and below said heel slit to define a rear edge of said second joinder section.

3. The boot of claim 2 wherein the first and second openings at the first and second ends of said heel slit are filled with elastomeric material.

4. The boot of claim 1 wherein a first flap slit end opening is provided at the first flap slit inner end to extend through said boot into said cavity and at least upwardly from said first flap slit inner end to define a forward edge of said first joinder section and a second flap slit end opening is provided at the second flap slit inner end to extend through said boot into said cavity and at least upwardly from said second flap slit inner end to define a forward edge of said second joinder section.

5. The boot of claim 4 wherein said first and second flap slit end openings are enlarged openings which extend transversely above and below the first and second flap slit inner ends respectively.

6. The boot of claim 5 wherein said first end of said heel slit is positioned adjacent to said first joinder section and the second end of said heel slit is positioned adjacent to said second joinder section, a first enlarged opening is provided at the first end of said heel slit to extend through said boot into said cavity and transversely above and below said heel slit to define a rear edge of said first joinder section and a second enlarged opening is provided at the second end of said heel slit to extend through said boot into said cavity and transversely above and below said heel slit to define a rear edge of said second joinder section.

7. The boot of claim 6 wherein the first and second openings at the first and second ends of said heel slit and the first and second flap slit end openings arc filled with elastomeric material.

8. The boot of claim 4 wherein said first and second flap slit end openings are filled with elastomeric material.
