    Abstract: The wheel comprises an inner rim attached to a wheel hub e.g. by spokes, an outer rim for receiving a tire, and a resilient member between the rims which in use serves to absorb shocks from the surface over which the wheel passes. An opening for a valve is provided. The material of the member is polymeric, e.g. polyurethane foam.

    Abstract: A skate wheel includes an outer polymeric layer, an inner polymeric layer, and an intermediate layer. The inner polymeric layer has a hardness which is less than the hardness of the outer polymeric layer. The inner and outer polymeric layers are preferably comprised of polyurethane. The intermediate layer is made of a hard plastic or metal that extends through the cross-section of the roller wheel, separating the outer and inner layers. The intermediate layer prevents compression of the harder outer polymeric layer onto the softer inner polymeric layer. This provides a smoother ride while maintaining good precision and speed. The skate wheel may also include a decorative illumination device.

    Abstract translation: 滑冰轮包括外部聚合物层,内部聚合物层和中间层。 内部聚合物层的硬度小于外部聚合物层的硬度。 内部和外部聚合物层优选由聚氨酯组成。 中间层由硬塑料或金属制成,其延伸穿过滚轮的横截面,分离外层和内层。 中间层防止较硬的外部聚合物层压缩到较软的内部聚合物层上。 这提供了更平稳的乘坐,同时保持良好的精度和速度。 滑冰轮还可以包括装饰照明装置。
