In-line roller skate frame with self-retracting inner wheels

Abstract

There is provided an in-line roller skate frame, consisting of a main frame (which connects directly to the skate boot) and a pair of bogeys which pivot within the mainframe on transverse axes. Each bogey will hold a pair of wheels, one outer wheel and one inner wheel per bogey. Each bogey will be acted on by a return spring, actuating when there is no weight being applied to the wheels & pivoting the bogey such that the outer wheels descend and the inner wheels ascend. At full rotation, said bogeys will have pivoted to an extent that the inner wheels do not protrude below the side wall members of the main frame.

1 . In an in-line roller skate adapted to move in a travel direction relative to a skating surface, the skate having a skate boot with a toe portion, a heel portion and a generally horizontally extending sole; 
 Said in-line roller skate where the frame is comprised of a mainframe which connects directly to the boot, and a pair of bogeys which pivot within the mainframe on transverse axes;    Said in-line roller skate frame where said mainframe is comprised of first and second parallel side wall members extending vertically down from said sole, said first and second wall members being horizontally spaced apart and extending in said travel direction;    Said in-line roller skate frame where said bogeys are acted upon by their respective return springs, actuating when there is no weight being applied to the wheels & pivoting the bogey such that the outer wheels descend and the inner wheels ascend;    Said in-line roller skate frame where said return springs act upon said bogeys, effectively retracting inner wheels such that at full rotation, said bogeys will have pivoted to an extent that said inner wheels do not protrude below said parallel side wall members of said mainframe;
