Chain barrier
First Claim
1. An automatic electrically operated mechanical barrier system comprising:
- a. a first stationary object;
b. a barrier coupled to the first stationary object and to a second stationary object;
c. means for mechanically raising and lowering the barrier, said means coupled to the first stationary object; and
d. means for locking the barrier in a taut, raised position which will remain locked when weight or force is applied, said means for locking coupled to the means for mechanically raising and lowering the flexible barrier.

Abstract
A remote-controlled mechanical device is described with a winding mechanism configured for preventing backwinding. The barrier 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 barrier 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.
