Chassis structure for roller skate with wheels in single line

摘要

The skate consists of a boot (1) mounted on a chassis (2) which carries a series of wheels (3) arranged in a single straight line. Each wheel is attached to the chassis at an independent rotation axis. The chassis is secured to the boot via a pair of lateral vertical plates (10) which are formed integrally with the boot or attached to it. The front and rear ends (10a,b) of the plates are secured to the chassis by pins which also form the rotation axes of the leading and trailing wheels. The chassis is formed as a single component by e.g. extrusion, with a pair of lateral walls (30) connected by spacers which define a series of cells into which the wheels are inserted.
