Abstract
Described herein is a locking device and method which integrates mechanical components in a hollow metal door frame with electronic access components. The electronic components override the original mechanical components of the lock to create a fail-safe situation in which the original mechanical lock may be disabled. In the preferred embodiment, my upgraded locking device can be re-installed within a hollow door frame, thereby minimizing service costs and doorframe modification costs. The electronically controlled component can be a cam retaining locking bar which contains a roll pin and an open area bordered by two cut sides. The open space eases lock installation with a door by avoiding protruding door structures such as metal tabs.
Claims1
A locking device, said locking device combining mechanical and electromagnetic access security components within a securing structure, said locking device comprising
- (A) an electromagnetic field generating device comprising
- (1) a solenoid, and
- (2) a metal solenoid housing, said metal solenoid housing comprising a separate physical article from said solenoid and said mechanical lock components, and
- (3) a cylindrical solenoid casing, said cylindrical solenoid casing comprising a separate physical article from said metal solenoid housing and said mechanical lock components, said cylindrical solenoid casing comprising a separate physical article from said solenoid, said cylindrical solenoid casing enclosing said solenoid, said metal solenoid housing enclosing said cylindrical solenoid casing, and
- (B) an electromagnetically controlled obstructing component with an attached hollow stem, said electromagnetically controlled obstructing component physically obstructing a mechanical component when said electromagnetically controlled obstructing component falls from a zero magnetic field created by said solenoid, said electromagnetically controlled physically obstructing component comprising a roll pin,
- said solenoid comprising copper wire,
