Patent ID: 7437900

Claim:
An externally releasable security bar system ( 50 ) for mounting on an inside surface of an inwardly swinging door ( 10 ) and engaging a floor surface ( 20 ) to prevent unauthorized entry through the door ( 10 ), comprising: (a) a mounting plate ( 100 ) fixedly secured to the inside surface of the door ( 10 ); (b) a bracing arm ( 200 ) having a proximal end ( 210 ) and a distal end ( 220 ), wherein the proximal end ( 210 ) is pivotally connected to the mounting plate ( 100 ) such that the bracing arm ( 200 ) may pivot between a secured position ( 202 ), wherein the distal end ( 220 ) is in contact with the floor surface ( 20 ), and an unsecured position ( 204 ), wherein the distal end ( 220 ) is elevated from the floor surface ( 20 ); (c) a release pin ( 300 ) operable to pivot the bracing arm ( 200 ) from the secured position ( 202 ) to the unsecured position ( 204 ), wherein the release pin ( 300 ) has a position ( 302 ) disengaged from the bracing arm ( 200 ) secured position ( 202 ) and a position ( 304 ) engaged with the bracing arm ( 200 ) unsecured position ( 204 ); (d) an actuation mechanism ( 400 ) operable to transfer the release pin ( 300 ) from the disengaged position ( 302 ) to the engaged position ( 304 ); and (e) a locking mechanism ( 500 ) for allowing selective operation of the actuation mechanism ( 400 ) such that when the locking mechanism ( 500 ) is locked, the actuation mechanism ( 400 ) is inoperable, and when the locking mechanism ( 500 ) is unlocked, the actuation mechanism ( 400 ) is operable.
