Roller-skates/sneakers with separable wheels

Abstract

Roller-skates/sneakers with two pairs of separable wheels, by which the problem of their alternative adjusting for walking or roller-skating is solved, and which are at the same time safe, maneuverable, practical and simple to manufacture. The roller-skates consist of sneakers, which are laced with laces, an insole and two pairs of wheels separably fixed in the insole. The insole, which follows the shape of the foot and contains the front and rear axle and forms the load-bearing construction, is built into the lower part of the sneaker inside the sole. The wheel consists out of the middle plate lined with silicone rubber, an interchangeable mask, two bearings on the rims of central hollow part of the wheel, as well as two washers made of steel with two lids on the side of the wheel facing the sneaker.
