  • Publication number: 20060079148
    Abstract: A toy comprising an object (12) which performs a spherical function, such as a striker for drum. The object (12) comprises a generally spherical body (30) having surface regions (40, 42, 44, 46) which together define a spherical surface area that performs the spherical function of the object. The object (12) also has grooves (32, 34, and 36) and throughways (38) which define air passages configured to allow for the passage of air through a child's windpipe regardless of how the object (12) is lodged therein.

  • Publication number: 20050153626
    Abstract: A toy percussion instrument that is characterized by a novel method of attaching a tether to a striker and/or main instrument body. The new location of attachment enables compliance with stringent safety standards without detracting from the playability of the toy instrument. In particular, two tethered strikers can be provided while still satisfying cord maximum perimeter standards and at the same time allowing an appropriate length of cord to play the instrument without difficulty. The provision of two tethered strikers enables a more realistic instrument while satisfying a parent's preference to have the tethers. In particular, The striker attachment location is spaced inwardly from the ends of the striker, thereby to allow a shorter tether to be used while still allowing the instrument to be played without difficulty.
