摘要： A pitch break connector is provided. The pitch break connector has an outside and inside rigid member. Each member has a first generally U-shaped channel defined by a spine member between first and second legs. Each member has a first and a second pivot end portion. A hinge pivotally connects the inside and outside members through the pivot end portions in a generally longitudinally opposing position. In this configuration, the first and second end portions of the inside member can be pivotally accepted into a cavity defined by the generally U-shaped channel of the outside member when the members are pivoted about the hinge.

摘要： An in-line wheeled skate which includes a rolling element between the wheels that enables the skater to jump up on a rail and roll down the rail sideways, as in `extreme skating` maneuvers, by placing the skate on the rail with the rolling element bearing upon the rail surface. Adjustable brakes provide control of the speed of sideways motion. The rolling element is provided as part of an attachment or lower structure to be secured to an in-line skate.
