GADIEV'S ROLLER SKATES Russian patent published in 2010 - IPC A63C17/00 A63C17/14 

FIELD: sports.

SUBSTANCE: roller skates comprise frame and support rollers, which are fixed in frame with the possibility of rotation, moreover, in front part of frame, beside front support roller, there is front combined thrust cap installed, which covers the roller at the front, and two additional blocked rollers are installed in cap on both sides of front main support roller, and their plane of rotation is parallel to plane of rotation of the main support rollers, and axes of rotation of additional blocked rollers are displaced to axis of front main support roller and are installed within the limits of external radius of front main support roller so that lower point of front blocked rollers is always higher than lower point of main support rollers. Curved line that connects lower point of front main roller, lower points of front additional rollers and lower point of front combined thrust cap precisely follows line of slide and cap of sliding skate. Ratchet gears are installed at additional blocked rollers and interact with catch pawls installed in front combined thrust cap, and back braking cap is arranged in back part of skate frame, covering back main thrust roller at the back. In back braking cap, on both sides of back main support roller, there are two back braking rollers arranged, planes of rotation of which are parallel to plane of rotation of the main support rollers, and axes of rotation of back additional braking rollers are displaced towards axis of back main support roller and are installed within the limits of external radius of back main support roller so that lower point of back braking rollers is always higher than lower point of main support rollers, and toothed gears are arranged on back additional braking rollers, being permanently engaged with toothed gears installed on back main support roller, therefore, mutual braking of back main support roller and back braking roller is achieved when back additional braking roller touches surface as a result their rotation in various directions and with various angular speeds.

EFFECT: improved consumer properties of skates with simultaneous preservation of their dimensions and reliability.
