Abstract:
A rolling circle for both recreational and exercise use, comprising:a) a hard rubber open circle having a round cross section and a outer surface which contacts a playing surface and an inner surface while a magnetic is permanently attached and positioned within the round cross section of the circle, b) an extendable stick with a proximal handle end and a distal end with a hook member attached thereto, c) the hook member having a resilient hook finger that extends from a connecting portion and defines a central area for receiving a portion of the open circle, an end of the resilient hook finger is separated from the connecting portion to form an entry way into the central area, d) a magnetic sensor is positioned adjacent to the distal end of the stick and near the hook member and is further positioned so that as the circle rotates while being captured in the central portion of the hook member the magnetic sensor creates an electrical signal each time the magnet on the circle passes the magnetic sensor, e) the proximal handle end further comprises a hand grip portion providing a comfortable gripping area for a user, a liquid crystal display mounted to a flat top portion of the handle, a user pulse rate detector mounted within the gripping area of the handle, and electrical circuitry mounted within the handle, f) the electrical circuitry further comprises a timer, a power supply, an on/off switch, and a processor which receives electrical signals from the magnetic sensor, pulse rate detector and timer and then selectively displays the time, user's speed, distance traveled, or pulse rate on the liquid crystal display.
