Abstract
A spinner anchors to a variety of magnetic and non-magnetic surfaces. The spinner includes a base, a spinner arm rotatably coupled to the base, and an indicator coupled to the spinner arm. The base of the spinner is shaped to receive a coupling member, such as a cylindrical magnet, configured to anchor the spinner to a plurality of surfaces regardless of their orientation and maintain its location relative to the support surface while the spinner arm and indicator rotate.
Claims17
A spinner couplable to a support surface, the spinner comprising:
- a base defining a central axis;
- a spinner arm coupled to and rotatable with respect to the base about the central axis;
- and
- a coupling member to removably couple the base to the support surface, the coupling member sufficient to maintain the location of the base on the support surface regardless of the orientation of the central axis or the rotation of the spinner arm;
- wherein the spinner arm further includes an indicator coupled thereto;
- and
- wherein the indicator defines a center of mass, and the center of mass is substantially co-axial with the central axis.
A spinner couplable to a support surface, the spinner comprising:
- a base defining a central axis;
- a coupling member to removably couple the base and the support surface;
- a spinner arm coupled to and rotatable with respect to the base about the central axis, the spinner arm including a first alignment mechanism;
- and
- an indicator couplable to the spinner arm and defining a center of mass, the indicator including a second alignment mechanism engageable with the first alignment mechanism to position the indicator on the spinner arm such that the center of mass of the indicator when coupled to the spinner arm is substantially co-axial with the central axis.
