Abstract

A skate including a boot having a toe portion, a heel portion and a base. A frame is adapted to rotatedly mount a plurality of wheels to the base of the boot. The skate also includes pivot structure for allowing the toe portion and the heel portion of the boot to pivot, flex or hinge relative to each other without interference from the frame so as to enhance the comfort level of the boot.

Claims

1. A skate comprising:

a boot having a heel portion and a toe portion, the boot being constructed and arranged to allow for pivotal movement between the heel portion and the toe portion; and

a frame including a first portion fastened to the toe portion of the boot and a second portion fastened to the heel portion of the boot, the frame also including pivot structure for allowing the first and second portions of the frame to pivot relative to each other in response to pivotal movement between the heel portion and the toe portion of the boot.

2. The skate of claim 1, wherein the pivot structure includes a pivot member connecting the first and second portions of the frame, the pivot member being slidingly received within a curved slot defined by one of the first and second portions of the frame such that the pivot member slides within the slot to allow the first and second portions of the frame to pivot relative to each other.

3. The skate of claim 1, wherein the pivot structure includes a pivot member pivotally connecting the first and second portions of the frame, and a slide mechanism for allowing the second portion of the frame to slide with respect to the heel portion of the boot.

4. An in-line-skate comprising:

a boot having a toe portion, a heal portion and a base, the boot also including a first pivot structure between the heel portion and the toe portion of the boot;

a frame connected to the base of the boot, the frame including a first portion fastened to the toe portion of the boot and a second portion fastened to the heel portion of the boot, the frame including a second pivot structure for allowing the first and second portions of the frame to pivot relative to each other, wherein the first and second pivot structures cooperate to allow the heel and the toe portions of the boot to flex relative to each other; and

first and second sets of tandemly arranged wheels, the first set of wheels being rotatedly connected to the first portion of the frame and the second set of wheels being connected to the second portion of the frame, wherein the first and second sets of wheels pivot relative to each other when the boot flexes.

5. The skate of claim 4, wherein the second pivot structure includes a pivot member connecting the first and second portions of the frame, the pivot member being slidingly received within a curved slot defined by one of the first and second portions of the frame such that the pivot member slides within the slot to allow the first and second portions of the frame to pivot relative to each other.

6. The skate of claim 4, wherein the second pivot structure includes a pivot member pivotally connecting the first and second portions of the frame, and a slide mechanism for allowing the second portion of the frame to slide with respect to the heel portion of the boot.

7. An in-line-skate comprising:

a boot;

a frame connected to the boot;

a single row of tandemly arranged wheels, the wheels being rotatedly connected to the frame; and

pivot structure constructed and arranged for allowing the boot to flex at a predetermined location adapted to be in alignment with a wearer'"'"'s metatarso-phalangeal articulations.

8. The in-line-skate of claim 7, wherein the frame includes first and second portions, and the pivot structure includes a pivot member connecting the first and second portions of the frame, the pivot member being slidingly received within a curved slot defined by one of the first and second portions of the frame.

9. The in-line-skate of claim 7, further comprising a spring structure for biasing the boot toward an unflexed orientation.

10. The in-line-skate of claim 7, further comprising an ankle joint defined by the boot.
