ABSTRACT:
Improved lock blocking plates and door jamb striker plates for use with entrance doors, the plates being utilized to prevent forcing or jacking open of dead bolt or spring bolt latches, together or singularly, while preventing inclement weather elements including rain water and wind from being received into the space existing between the door end face and the door jamb. The invention includes several alternate embodiments for uses with single doors that open in or out and double doors and provide for rain drainage, wind and rain deflection and a guard plate to prevent unauthorized opening of a dead bolt or spring latch bolt found in conventional doors and door jambs. Also included in the improvements is a downward and outward angularly formed top guard plate edge which allows rain water which might otherwise seep into the locking mechanism to drain outwardly and downwardly for preventing moisture in the lock operating mechanism. An additional improvement includes the utilization of full length interlocking door guard strips having an outer deflector surface to divert wind driven rain away from the door jamb spacing of the entrance doors.
