  • Patent number: 5979184
    Abstract: A combination jewelry article and toy for use as both a necklace and a yo-yo. The combination jewelry article and toy includes a pendant having a front portion and a rear portion connected by a post, and at least one aperture disposed in the pendant. A first end of a cord or chain is attached to the post of the pendant, while a second end of the cord is attached to an engagement member, such as a clasp. In a first position, the clasp is secured through the aperture in the pendant, so that both ends of the cord are attached to the pendant. In this manner, the cord is formed into a large loop which may be positioned around the neck of the user so that the pendant and cord may be worn as a necklace. In a second position, the clasp is secured to the cord in the area of the second end so that a finger loop is formed. The user can then wrap the cord around the post of the pendant, insert his or her finger into the finger loop at the second end of the cord and use the pendant and cord as a yo-yo.
