Patent number: 9101822Abstract: A magic cube structure includes a central core, a plurality of central blocks, a plurality of resettling devices, a plurality of elastomers, a plurality of side blocks and a plurality of corner blocks. Whereby, when one central block is rotated relative to the central core by an outer force, one central block is pressed by the corresponding resettling device and is axially moved away therefrom. Simultaneously, the recovery force of the corresponding elastomer is increased, so that a torque imposed on the central block is created; when the rotation operation is completed, the torque makes the central block fitly abutted against the corresponding resettling device. As a result, the recovery force returns to former state.Type: GrantFiled: September 11, 2014Date of Patent: August 11, 2015Inventor: Cheng Wei Liu
