  • Patent number: 9685144
    Abstract: A toy piano including one or both an enlarged sound plate intermediate the sound bar of the toy piano and its sound board, and a sound box into which the sound board is incorporated. Preferably, the sound plate extends beyond the normal edges of the sound bar in which the longitudinal tines of the toy piano are mounted so as to lie adjacent to the sound board over a larger area. Likewise, the sound box should preferably be shaped so as to be somewhat wider (measured in the longitudinal direction of the tines) towards the end where the tines are longest (and produce lower tones) and somewhat narrower towards the end where the shorter tines (producing higher tones) are located. It preferred shape is characterized by somewhat convex curves at the more treble and bass ends, respectively, of the sound box with a somewhat concave curve intermediate these two ends. The backboard of the sound box can be bowed outward for enhance acoustics.

  • Patent number: 8013227
    Abstract: In order to be able to salvage toy pianos that have become damaged during shipping, a structure and process for manufacture of toy pianos has been developed wherein (1) stop piece (or block members) are permanently affixed to certain side forming members, allowing certain other side forming members to be non-permanently affixed thereto via connectors non-permanently anchored to said block members; (2) horizontal slits are provided near the bottom of certain side members to fit over edges of the bottom member, allowing the edges of said bottom member to firmly but non-permanently nest therein; and (3) vertical grooves are provided near ends of certain side members to fit over ends of certain other side members, allowing the ends of said certain other side members to firmly but non-permanently nest therein. These innovations each assist, and together greatly facilitate, the production of a toy piano that is solid and durable in structure while simultaneously allowing easy replacement of damaged parts.

  • Patent number: 7671259
    Abstract: In order to be able to salvage toy pianos that have become damaged during shipping, a process has been developed to manufacture toy pianos using a set of predetermined jigs in order to cut the parts of the piano in order to achieve uniform pieces in the event of damage to the piano and the replacement of a piece on the piano becomes necessary. Rather than the entire piano needing to be discarded the damage part can simply be removed and a new piece put in its place.
