ABSTRACT:
An improved structure for roller skate in which the installation and the structure of the single-row rollers are improved. The in-line rollers in the conventional roller skate are redesigned so that the rollers can be installed on the left and the right hand sides of the shoes to form a dual-row roller skate. The structure can also be modified to have a single roller in the front and dual rollers in the rear, or the rollers of the structure can also be arranged in a single row. Such configuration allows a beginner to use a dual-row four-wheel roller skate for balanced practice, and then the roller skate can be changed into a three-wheel type when the user is in his intermediate stage. Finally, the user can be advanced by using the two-wheel in-line structure. The entire practicing process requires only one pair of roller skates, therefore, it is an economical and practical roller skate structure.
