SKATE BLADES WITH IMPROVED TURNING PROPERTIES Russian patent published in 2019 - IPC A63C1/30 

FIELD: sports.

SUBSTANCE: invention describes skate blade (10), having outside edge and inside edge (2, 3), in middle region (1) of which outside edge and inside edge (2, 3) are parallel and have the same height, and the blade has anterior region (4) in front of middle region (1), where height (z) of edges (2, 3) increases in forward direction relative to height (z=0) assumed at the middle region, and posterior region (5) behind middle region (1), where height (z) of edges (2, 3) increases in rearward direction relative to height (z=0) assumed at the middle region, wherein width coordinate (y) of at least one edge (2, 3), at least in anterior or in posterior region (4, 5) increases along an arched curve with the distance from middle region (1) relative to vertical central plane (6) interpreted at middle region (1), and for all points with equal distance (x) in front or behind middle region (1), where width of blade (10) exceeds the width in middle region (1), both edges (2, 3) have height coordinate (z) exceeding zero.

EFFECT: skate blades with improved turning properties are disclosed.
