A merchandise dispensing apparatus for deterring theft includes a housing having a plurality of walls defining an interior space within the housing. At least one merchandise support module is mounted in the housing and includes an electro-mechanical ejector located adjacent a front end of the at least one module. The ejector includes an electrical motor with an output shaft, along with an ejector plate movably mounted in relation to the housing. A gear train connects the output shaft of the motor to the ejector plate. A relay selectively provides electrical power to the motor.
1. A merchandise dispensing apparatus for deterring theft, comprising:
a housing comprising a plurality of walls defining an interior space within the housing;
at least one merchandise support module mounted in the housing, the at least one module comprising an electro-mechanical ejector mechanism located adjacent a front end of the at least one module, the ejector mechanism including:
an ejector housing,
an electrical motor mounted to the ejector housing and including an output shaft,
an ejector plate mounted to the ejector housing and movably mounted in relation to the ejector housing and having a retracted position and an extended position,
a biasing member mounted to the ejector housing and adapted to directly contact the ejector plate and bias the ejector plate linearly into its extended position, the biasing member having a compressed state corresponding to the retracted position of the ejector plate and an expanded state corresponding to the extended position of the ejector plate,
a gear train located within the ejector housing and connecting the output shaft of the motor to the ejector plate,
a relay for selectively providing electrical power to the motor, and
a user input member for selectively operating the motor via the relay,
wherein the ejector plate further comprises a latch member located in the ejector housing for retaining the ejector plate in the retracted position against the bias of the biasing member.
2. The apparatus of claim 1 wherein the biasing member comprises a spring which urges the ejector plate linearly upwardly into its extended position.
3. The apparatus of claim 1 wherein the user input member comprises a button.
4. The apparatus of claim 1 wherein the gear train comprises at least two speed reduction gears.
5. The apparatus of claim 4 wherein the at least two gears are compound gears each including a larger diameter toothed peripheral section and a smaller diameter toothed peripheral section.
6. The apparatus of claim 4 wherein the gear train comprises three gears.
7. The apparatus of claim 6 further comprising a rotary lock mounted to the third gear and engaging the ejector plate.
8. The apparatus of claim 7 further comprising a tooth disposed on the rotary lock and engaging the latch member of the ejector plate.
9. The apparatus of claim 1 where a plurality of spaced modules are arranged in a side by side manner in the housing.
10. The apparatus of claim 9 where a plurality of spaced user input devices are accessible to customers, each input device being connected to a respective module.
