In-line roller skates with adjustable dimension

Abstract

An in-line roller skate with adjustable dimension for adjusting the dimension of the shoe cap of the roller skate includes an adjusting mechanism which adopts a thread design. It has a first adjusting member located on the truck and a second adjusting member located on the bottom section of a two-piece shoe cap to couple with a turning knob at the rear end. By rotating the turning knob, the matching worms on the adjusting mechanism may be moved forwards or rearwards to drive the shoe cap to move forwards or rearwards. When rotation of the turning knob is stopped, the screw threads on the adjusting mechanism are latched to anchor the shoe cap, therefore the dimension of the roller skate may be adjusted.
