ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention is directed to a portable security device which fits a variety of sizes of doors and is easily mounted to, and removed from, door jambs without the necessity of hardware such as screws or bolts.
2. Description of the Related Art
It is desirable and important to keep dangerous items, such as guns, and valuables, such as money and jewelry, in safe places which are inaccessible to children and burglars. Curious children will search throughout the house to find hidden dangerous items and burglars are adept at finding hidden valuables. Therefore, it is wise if these items are kept behind locked doors which cannot be opened by children or burglars, but can be easily opened by the rightful owner. The prior art is familiar with hasp locks for this purpose. However these locks require permanent attachment to door jambs with screws or bolts and therefore lack the convenience of ease of selecting which door is to be secured.
SUMMARY OF THE INVENTION
The object of the present invention is to provide a device which is easy to install, will lock a door securely, and can be easily removed and moved to another door without the use of tools. The device of the present invention is simple to make and use, versatile, and effective. The device contains two plates which are hinged together. For purposes of easy identification, the plate which fits onto the door jamb is termed the inner plate, while the plate which covers the inner plate and fits toward the user is called the outer plate. Each plate is made up of two panels which are perpendicular to each other. The first panel of the inner plate fits on the strike plate of a door jamb and contain a lock tab which fits into the bolt hole in the strike plate. The second panel of the inner plate contains a horizontal protrusion which contains an opening for a holding mechanism. The first panel of the outer plate and the second panel of the inner plate are rotatably secured by a hinge. The first panel of the outer plate contains a horizontal slot to allow for passage of the horizontal protrusion of the second panel of the inner plate. The first panel of the outer plate also contains a hole for securing a chain for holding the holding mechanism. The second panel of the outer plate is so formed as to fit between the juncture of the first and second panels and the closed door. When the device is fitted into place on the strike plate of a door jamb and the device is in the closed position, the horizontal protrusion fits through the horizontal slot of the first panel of the outer plate. The opening in the horizontal protrusion for receiving the holding mechanism is thus exposed. The holding mechanism, which is similar in appearance to a key, fits through the opening in the horizontal protrusion. A lock hole in the holding mechanism receives a padlock, securing the holding mechanism in place.
