Abstract
A rotating user-propelled playground equipment assembly or whirl including an equipment support base, a spindle secured to the support base, a rotatable platform assembly supported at least in part by the support base. The rotatable platform assembly includes a hub assembly rotatable about the spindle. A pressure wheel is positioned to constantly rollingly engage the hub assembly. A compression spring urging mechanism is connected to the pressure wheel and urges the pressure wheel into rolling engagement with the hub assembly and thereby automatically retards the rotation of the rotatable platform assembly about the spindle.
