  • Publication number: 20070243792
    Abstract: A hula hoop has a plurality of arched coupling units, which are plastic molded articles and coupled to one another in sequence to complete a circular assembly. Each coupling unit is centrally formed with an expanded acupressure portion, and has one end formed into a bolt-shaped coupling portion and the other end formed into a nut-shaped coupling portion. Thereby, the bolt-shaped coupling portion of one coupling unit is able to be forcibly fitted into and fastened to the nut-shaped coupling portion of another neighboring coupling unit. Each coupling unit is densely wound, throughout an outer peripheral surface of the overall body thereof except for the coupling portions, by a braid that is made by interweaving a plurality of strands. Metal or plastic connecting members are fitted around the respective coupling portions between the neighboring coupling units in the course of assembling of the coupling units.

  • Patent number: 6896576
    Abstract: A yo-yo wherein each half body has three essential elements: a axle/hub assembly, a rim, and an interior space containing flexible, compressible material, such as an elastomer or a bladder filled with gas, liquid, or gel. The axle/hub assembly and the rim contain the flexible, compressible material but are not rigidly in contact with each other. In this way a shock to the rim and vibrations to the string are suppressed and dampened by the flexible, compressible material. For greater flexibility and shock damping, there could be cavities (grooves or holes) in the elastomer material or for greater lateral stability, the rim could overlap the gaps between it and the axle/hub assembly. There could also be containment/alignment walls extending into the flexible, compressible material or O-rings in gaps between the rim and the axle/hub assembly.

  • Patent number: 6089945
    Abstract: A yo-yo having a multi-image lenticular instruction system. The system is incorporated into at least one of the yo-yo's side members via a side cap that is secured to the side member and is readily visible. The instruction system functions by displaying sequential images showing how to perform a predetermined yo-yo trick. A user can manually manipulate the yo-yo to display the images in either a forward or reverse order and at any speed the user desires. By watching the images, the user can easily see how to perform the displayed yo-yo trick.
