Abstract

This invention relates to a toy's eyebrow and mouth moving mechanism, involving a base on which is fixed a stand and a main unit that accommodates the integral mechanism of this invention, on one side of the main unit is a motor which rotation can be switched on and off by a control circuit that is installed inside the base, the motor driving an eyebrow unit that is located at the upper part of the main unit, through a medium gear, an upper reducing gear and an upper activating gear, the motor also driving a lower jaw unit that is located at the lower part of the main unit, in such a construction, when the power of this invention is switched on, the control circuit will activate melodic music and flashing light (the lamp installed inside the eyeball), on the other hand the motor will activate the eyebrows and mouth to blink and move according to the music and rhythms, thus providing lively and amusing effects, and because of its more simplified construction than the prior art of the same category, this invention will effectively reduce production costs and enhance market competitiveness.

An eyebrow and mouth mechanism for a toy, comprising:

a main unit;
a transmission arrangement, including:
an upper activating gear having an axle;
an upper reducing gear in engagement with said upper activating gear;
a medium gear in engagement with said upper reducing gear;
a lower activating gear having an axle;
a lower reducing gear in engagement with said lower activating gear;
and
a motor installed on a side of said main unit and being adapted to be turned on or off by a control circuit, the motor driving said upper activating gear through said medium gear and said upper reducing gear, and driving said lower activating gear through said lower reducing gear;
an eyebrow unit installed on an upper part of said main unit, and including:
two eyeballs that are respectively fixed on opposite sides of said main unit;
and
two eyebrow plates that are fixed to two ends of said axle of said upper activating gear and that are adapted to simulate eyebrows, said two eyebrow plates being located in front of said eyeballs, said two eyebrow plates rotating at specified angles with said upper activating gear to create an upward and downward lifting movement of eyebrows;
and
a lower jaw unit installed at a lower part of said main unit, and including:
two support plates, each having a shaft that is fixed to a respective end of the axel of said lower activating gear;
a lower jaw plate fastened to said two support plates;
and
a spring disposed around one of said shafts, and having one end inserted into the side of said main unit, and having another end inserted into one of said support plates, said lower jaw plate being maintained at a level state by a support of said spring;
wherein when said motor is activated by the control circuit, said upper activating gear and said lower activating gear are rotated at specified angles, said upper activating gear and said lower activating gear in turn driving said eyebrow plates and said lower jaw plate to open, and when said motor is deactivated, a resiliency of said spring causes said eyebrow plates and said lower jaw plate to close.
