Abstract

A remotely releasable security system for securing a barrier across a window opening to prevent unauthorized access to the interior of a building via a window, and to permit removal of the barrier for escape in an emergency or for maintenance. The security system includes a security barrier, a locking mechanism for securing the barrier to a window frame, a radiant energy receiver operably connected to the locking mechanism, and a radiant energy remote control transmitter for signaling the receiver to release the locking mechanism so that the barrier may be removed.

Claims

1. A remotely releasable security system comprising:

a security barrier positioned across a window opening;

a locking mechanism for releasably securing the security barrier to a window frame which defines the window opening, wherein the locking mechanism comprises one or more male/female lock sets in line with corresponding shear pin interference mechanisms;

a radiant energy receiver operably connected to the locking mechanism; and

a radiant energy remote control for signaling the receiver to release the locking mechanism.

2. A remotely releasable security system as defined in claim 1 wherein the radiant energy is within the radio frequency spectrum.

3. A remotely releasable security system as defined in claim 1 wherein the security barrier is selected from the group consisting of security glass and security screen.

4. A remotely releasable security system comprising:

a security barrier positioned across a window opening; and

a locking mechanism for releasably securing the security barrier to a window frame which defines the window opening, wherein the locking mechanism comprises one or more male/female lock sets in line with corresponding shear pin interference mechanisms.
