Patent attributes
A wrist exerciser including a housing and a gyroscopic member is disclosed. The housing is structured to include a casing structure, a rail, and one or more channels along a direction of the casing structure, in which the channels penetrate through the casing structure forming an empty space to buffer a force caused by an impact to the housing. The gyroscopic member is moveably disposed at the rail and includes a ring being inside the housing and slidably disposed at the rail; and a rotor being inside the housing and comprising a ball and a shaft, the shaft penetrating the ball, with its two opposite ends connected to the ring for the shaft to rotate relatively to the ring. The housing is structured to absorb an impact force to protect the structure and functionality of the wrist exerciser.
