Remote controlled mechanical chain barrier
First Claim
1. An electrically operated barrier system for preventing access to a passageway, comprising:
- a. a first stationary object placed on one side of the passageway;
b. a second stationary object placed on an opposite side of the passageway from the first stationary object;
c. a flexible barrier coupled to both the first stationary object and the second stationary object to hang over the passageway and prevent access to the passageway between the first and second stationary objects;
d. means for raising the flexible barrier to a raised and locked position in response to an electrical signal, said means for raising coupled to the first stationary object;
e. means for lowering the flexible barrier to a relaxed position from the raised and locked position in response to the electrical signal, said means for lowering coupled to the first stationary object; and
f. means for securing comprising a sprocket pulley and stop-lock stud for securing the flexible barrier in the raised and locked position when weight or force is applied to the flexible barrier, said means for securing coupled to the means for raising the flexible barrier and to the first stationary object, wherein the sprocket pulley is pulled towards and engaged by the stop-lock stud when weight or force is applied to the flexible barrier.

Abstract
A remote-controlled mechanical locking chain gate has an electrically controlled winding mechanism with a locking device to keep the chain tight and prevent the chain from loosening when pressure is applied to the chain thus putting it into a locked position. The chain gate can be lowered or raised from a remote location using an accompanying remote control device. The motor and mechanics used to raise and lower the chain are modular for easy repair and replacement, and enclosed in a protective covering in order to protect them from damage or tampering. The motor can be operated by alternating current or direct current to provide the user with flexibility and allow the gate to be operated either by direct wire to an electrical source or by one or more batteries or recharging solar cells, and used in remote places where there is no access to electrical power.
