Title:
ヨーヨー
Document Type and Number:
Japanese Patent JP4843096
Kind Code:
B2
Abstract:
The invention is an improved yo-yo that features two side assemblies that sandwich a center axle onto which the yo-yo's tether may be secured. According to a first embodiment, each of the side assemblies preferably includes a releasable, disk-shaped rim piece. By replacing one set of replaceable rim pieces with another, a user can quickly and easily change the yo-yo's shape, look and/or functionality. To remove a rim piece, one first removes a lock ring that is secured to the rim piece and blocks a number of openings that lead to grooves in a center-located hub. Next, one employs a twisting movement of the rim piece to cause a number of tabs attached to the rim piece to slide in the hub's grooves until the tabs are aligned with the openings. The rim piece can then be disengaged from the yo-yo.
