First Claim
Patent Images
1. A skate comprising:
- a skate body with an anterior toe end and a posterior heel end;
a carriage frame pivotally coupled to the skate body to pivot about a pivot axis wherein the pivot axis has a horizontal position and a vertical position wherein the horizontal position of the pivot axis of the carriage frame is substantially coincident with or anterior to the anterior toe end of the skate body;
at least one ground engaging element coupled to the carriage frame;
whereby the at least one ground engaging element can pivot with the carriage frame relative to the skate body to maintain contact with a ground surface throughout a range of pivoting of the skate body relative to the ground surface.

Abstract
A skate with a main skate frame, a skate boot, and a carriage frame pivotally coupled to the main skate frame. At least one ground engaging member, such as a wheel or a runner blade, is coupled to the carriage frame for pivoting therewith. The main skate frame can pivot laterally, dorsally, or both laterally and dorsally relative to the carriage frame. Lateral pivoting can be achieved, for example, with a lateral pivot shaft or with an arcuate passage with a plurality of axles that also enable dorsal pivoting.

18. A skate comprising:
-
a skate body with an anterior end and a posterior end;
a carriage frame with at least one ground engaging element;
a pivoting mechanism that pivotally couples the carriage frame to the skate body wherein the pivoting mechanism enables the carriage frame to pivot away from the skate body about an effective pivot axis that has a horizontal position and a vertical position and wherein the effective pivot axis is physically displaced from the pivoting mechanism;
whereby the carriage frame pivots about an effective pivot axis without requiring the pivoting mechanism to be located at the effective pivot axis and whereby the carriage frame can pivot relative to the skate body to maintain contact with a ground surface throughout a range of pivoting of the skate body relative to a ground surface. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32)
