CHAIN DRIVEN GATE AND SECURITY SYSTEM

摘要

A chain driven gate and security system is provided. The system includes a gate which is opened and closed by a gate operator. The gate operator includes a chain and a motor having a rotatable sprocket for engaging the links of a chain. The gate and security system includes a sensor for detecting whether the chain has been severed, an alarm for producing a visible or audible alert, and a processor connected to the motor, sensor and alarm. The processor activates an alarm in the event that the processor indicates that the gates should be closed, but that the chain has been severed.

主权项

1. A chain driven gate and security system comprising:
a gate for selectively blocking a portal, said gate having a first edge and a second edge and slideable in a first direction and a second direction between said gate being in an open condition and a closed condition; a length of chain having a first end and a second end, said chain's first end affixed to said gate and said chain's second end affixed to said gate; a motor with a rotatable sprocket which engages said chain, wherein activation of said motor rotates said sprocket to cause said chain to pull and slide said gate in either the first direction or the second direction so as to move said gate to an open condition or closed condition; a sensor for detecting whether said chain has been severed; an alarm for producing a visible or audible alarm; and a processor connected to said motor, said sensor and said alarm, wherein said processor activates said alarm in the event that said sensor detects said chain has been severed.
