Benefits of technology
It is one object of the present invention to provide a transmission mechanism for music box ornament which is simple in structure and inexpensive to manufacture. It is another object of the present invention to provide a transmission mechanism for music box ornament which moves different ornaments in different ways. According to one aspect of the present invention, the transmission mechanism comprises a rotary wheel rotated by the reproducer of a conventional wind-up music box mechanism and having an eccentric rod, a locating block fixedly mounted within a base plate within which the wind-up music box mechanism is mounted, a follower plate supported on the eccentric rod and vertically reciprocated by it along a downward rod on the locating block, and a tappet rod inserted through a hole on the locating block and driven by the follower plate to reciprocate an ornament. According to another aspect of the present invention, the base plate is supported on a rocker, having a spring supported T-rod stopped below the eccentric rod of the rotary wheel, the T-rod being alternatively moved up and down by the eccentric rod of the rotary wheel and the spring to force the rocker moved forwards and backwards alternatively when the wind-up music box mechanism is operated.
Problems solved by technology
However, conventional transmission mechanisms for use with wind-up music box mechanism are commonly complicated and expensive.

Embodiment Construction
Referring to FIGS. 1, 2A, and 2B, the ornament, referenced by 11, is driven by the driving mechanism (clockwork) 3 of the wind-up music box mechanism 2 of a music box 10. The wind-up music box mechanism 2 is a conventional device and supported on the base 1 of the music box 10. The central shaft (not shown) of the reproducer 21 of the wind-up music box mechanism 2 has one end coupled to the driving mechanism 3, and an opposite end coupled to a rotary wheel 4. The rotary wheel .[.Q.]. .Iadd.4 .Iaddend.has an eccentric rod 5 at an outer side. A locating block 8 is fixedly mounted within the music box 10, having a channeled vertical wall 81 and a flat horizontal wall 82 perpendicularly extended from the channeled vertical wall 81 at the top. The flat horizontal wall 82 has a downward guide rod 84 vertically disposed near one end, and a through hole 83 near an opposite end. A follower plate 9 is supported on the eccentric rod 5 and moved by it along the channeled vertical wall 81 of the...

A transmission mechanism for music box ornament, including a rotary wheel rotated by the eproducer of a conventional wind-up music box mechanism and having an eccentric rod, a locating block fixedly mounted within a base plate within which the wind-up music box mechanism is mounted, a follower plate supported on the eccentric rod and vertically 10 reciprocated by it along a downward rod on the locating block, and a tappet rod inserted through a hole on the locating block and driven by the follower plate to reciprocate an ornament.
Description
BACKGROUND OF THE INVENTIONThe present invention relates to a transmission mechanism for music box ornament which uses the reproducer of a wind-up music box mechanism to turn a rotary wheel with an eccentric rod, causing the eccentric rod of the rotary wheel to reciprocate an ornament through a follower plate.Various music box-incorporated ornamental display assemblies have been disclosed, and have appeared on the market. These ornamental display assemblies are rotated or reciprocated by the the driving mechanism of a wind-up music box mechanism through a transmission mechanism. However, conventional transmission mechanisms for use with wind-up music box mechanism are commonly complicated and expensive.SUMMARY OF THE INVENTIONIt is one object of the present invention to provide a transmission mechanism for music box ornament which is simple in structure and inexpensive to manufacture. It is another object of the present invention to provide a transmission mechanism for music box orn...
