  • Patent number: 6162110
    Abstract: An accessory for diabolo juggling may take the form of hand held unit or a free standing unit. In each case, at least one stretchable, flexible, resilient and elastic member is supported by a frame. The elastic member, preferably a bungee cord, is free of any cross-member and in spaced parallel relation to any additional elastic members such that there is an unobstructed region on each side of the elastic member. In one form, there is a horizontal and vertical frame member with a plurality of elastic members supported in spaced parallel relation on transverse members mounted on the frame members. In use the diabolo is propelled toward the accessory, impinges on one or more cords and is propelled away due to the resilient nature of the cords. The free space on each side of the cord permits passage of the cones of the diabolo on each side of the cord to prevent the cone from contacting a fixed component of the accessory and thus slowing down the rotation of the diabolo.
