The longitudinal axis of each strike housing tooth plate screw hole 59 is perpendicular to the plane of tooth plate mounting surface 57. Each strike housing tooth plate screw hole 59 is a cylindrical hole with female helical thread cut into the inner diameter of the cylindrical hole. Female helical thread is sized to mate with the male cylindrical thread on strike housing tooth plate screws 47. Strike housing tooth plate screws 47 and strike housing tooth plate screw holes 59 function in tandem to reversibly rigidly attach strike housing tooth plate 40 to tooth plate mounting surface 57. Room side 52, first side 53, second side 54, and door opposite side 56 are each a rigid planar member that completely cover their respective side to make a completely closed side of the rectangular cuboid shaped member or box shaped member. In best mode, door opposite side 56 does not make an exact right angle with its four adjacent sides of the rectangular cuboid shaped member or box shaped member but rather is slightly askew to the four adjacent sides to make a trapezoidal shape on that side. Thus, in best mode, strike housing 50 is a rectangular cuboid shape on the door adjacent side and a trapezoidal cuboid shape on the door opposite side as depicted. Door adjacent side 55 is a rigid planar member with a deadbolt/latch clearance hole 58 and a plurality of wall mounted tooth plate screw holes 60. Deadbolt/latch clearance hole 58 is a rectangular or square shaped void or hole through the door adjacent side 55 of strike housing 50. Deadbolt/latch clearance hole 58 functions to provide clearance space for the latch or the deadbolt (not depicted) of the door lockset (not depicted). When the barn door (not depicted) is closed and the door lockset is latched or locked, the latch or the deadbolt of the door lockset moves to catch within deadbolt/latch clearance hole 58 to latch or lock the barn door (not depicted). When the door lockset is latched or locked, the latch or the deadbolt of the door lockset contacts the deadbolt/latch clearance hole 58 to prevent the barn door from opening when the barn door is attempted to be slid open. When the door lockset is unlatched or unlocked, the latch or the deadbolt of the door lockset moves to clear within deadbolt/latch clearance hole 58 to unlatch or unlock the barn door. When the door lockset is unlatched or unlocked, the latch or the deadbolt of the door lockset does not contact the dead bolt/latch clearance hole 58 when the barn door is opened. Each wall mounted tooth plate screw hole 60 is cylindrical hole through door adjacent side 55. Each wall mounted tooth plate screw hole 60 has an inner diameter and a longitudinal axis. The longitudinal axis of each wall mounted tooth plate screw hole 60 is perpendicular to the plane of door adjacent side 55. Each wall mounted tooth plate screw hole 60 must align with a wall mounted tooth plate screw hole 36 in wall mounted tooth plate 30 so that one wall mounted tooth plate screw 37 may pass through each set of holes. Each wall mounted tooth plate screw hole 60 must be tapered from the door adjacent side 55 in order to allow clearance space for the head of each wall mounted tooth plate screw 37 to countersink to be flush with the door adjacent side 55 of strike housing 50. The head of each wall mounted tooth plate screw 37 must be flush so that the barn door may contact the door adjacent side 55 of strike housing 50 when closed without obstruction or interference from the head of each wall mounted tooth plate screw 37.
Tamper proof wall mounted strike assembly for barn door 5 may further comprise one or more wall spacer plates 70. Each wall spacer plate 70 is a solid rigid planar member. Each wall spacer plate 70 is rectangular or square shaped with a height and a width. One or more wall spacer plates 70 function to extend the wall plate assembly from the wall or mount the wall plate assembly further from the wall to allow for proper alignment of the latch or lock from the barn door lockset with the deadbolt/latch clearance hole 58. The latch or lock from the barn door lockset must penetrate the deadbolt/latch clearance hole 58 for the lockset to work properly. Thus, the latch or lock from the barn door lockset must align with the deadbolt/latch clearance hole 58 when the barn door is closed. Barn doors come in a variety of thicknesses so sometimes one or more wall spacer plates 70 are required in order for this alignment to occur. Each wall spacer plate 70 has at least two wall screw holes 72 therein. Each wall screw hole 72 is cylindrical hole through each wall spacer plate 70. Each wall screw hole 72 has an inner diameter and a longitudinal axis. The longitudinal axis of each wall screw hole 72 is perpendicular to the plane of wall spacer plate 70. Each wall screw hole 72 must align with a wall screw hole 12 in wall plate 10, a wall screw hole 22 in tooth spacer plate 20, and a wall screw hole 38 in wall mounted tooth plate 30 so that one wall screw 39 may pass through each set of aligning holes. One or more wall spacer plates 70 are optional and are not an essential component of this invention.
Tamper proof wall mounted strike assembly for barn door 5 is assembled and installed as follows. It is first determined whether the barn door will be right opening or left opening. For a right opening door, the first side 53 of strike housing 50 is the upper end and the second side 54 of strike housing 50 is the lower end. For a left opening door, the second side 54 is the upper end and the first side 53 is the lower end. For a right opening door, the first edge of wall plate 10 is the upper edge and the second edge of wall plate 10 is the lower edge. For a left opening door, the second edge is the upper edge and the first edge is the lower edge. The wall plate tooth spacer plate assembly, comprising the wall plate 10 rigidly attached to the tooth spacer plate 20, is positioned in the proper orientation and location on the wall or door molding. Wall mounted tooth plate 30 is positioned in the proper orientation and location wherein the wall surface of the first planar member of wall mounted tooth plate 30 is adjacent to and in contact with the room surface of tooth spacer plate 20 so the wall screw holes 12,22,38 align with each other. Then one wall screw 39 is installed into each set of aligned wall screw holes 12,22,38 to rigidly attach the wall plate assembly to the wall or door molding. The strike assembly is then aligned with the wall plate assembly so that the teeth or merlons 32 of wall mounted tooth plate 30 mesh with, align with, or pass through the crenels 44 of strike housing tooth plate 40 and the teeth or merlons 42 of strike housing tooth plate 40 mesh with, align with, or pass through the crenels 34 of wall mounted tooth plate 30 in order to start to lock these members together as depicted in
