Striker plate, a door jamb assembly and a method of securing a striker plate to a door surround structure

A door jamb assembly comprising:

• a. a door surround structure having a recess for receiving a striker plate with grooves provided in walls of the door surround structure surrounding the recess;
• and
• b. a striker plate including:
• i. a body includes an insert with one or more openings, each of the one or more openings adapted to receive a respective lock bolt from a lock having one or more lock bolts;
• ii. the body includes at least two vertically oriented elongate mounting slot apertures facilitating mounting of the striker plate to a door surround structure, the at least two vertically oriented elongate mounting slot apertures receiving corresponding mounting screws for final fixing of the body in a desired vertical position relative to the door surround structure to vertically position the one or more openings of the insert relative to the lock bolt;
• and
• iii. the body further includes at least first and second oppositely disposed projections projecting outward substantially in a plane parallel to a plane defined by the insert, each of the oppositely disposed projections projecting outward a corresponding lateral projection distance and the projections being engaged with corresponding ones of the grooves of the door surround structure for holding the body in the door surround structure, the lateral projection distances of the projections acting to laterally position the body to a desired lateral position and prevent further lateral motion relative to the door surround structure, wherein at least one of the projections is resiliently movable relative to its corresponding groove and is engaged with said corresponding groove, which enables the body to be temporarily engaged and moved to the desired vertical position relative to the door surround structure and retained in the desired vertical position prior to final fixing of the striker plate to the door surround structure, the engagement between the first and second oppositely disposed projections and the corresponding oppositely positioned grooves avoiding any requirement of an installer holding the striker plate in position as the striker plate is finally fixed in the desired vertical position.

A method of securing a striker plate to a door surround structure, the method comprising the steps of:

• a. selecting a striker plate comprising:
• i. a body including an insert with one or more openings, each of the one or more openings adapted to receive a respective lock bolt from a lock having one or more lock bolts;
• ii. the body of the selected striker plate includes at least two vertically oriented elongate mounting slot apertures facilitating mounting of the striker plate to a door surround structure, the at least two vertically oriented elongate mounting slot apertures receiving corresponding mounting screws for final fixing of the body in a desired vertical position relative to the door surround structure to vertically position the one or more openings of the insert relative to the lock bolt;
• and
• iii. the body of the selected striker plate further includes at least first and second oppositely disposed projections corresponding to the door surround structure and projecting outward substantially in a plane parallel to a plane defined by the insert, each of the oppositely disposed projections projecting outward a corresponding lateral projection distance and the projections being configured to be engageable with corresponding oppositely positioned grooves in the door surround structure for holding the body in the door surround structure, the lateral projection distances of the projections acting to laterally position the body to a desired lateral position and prevent further lateral motion relative to the door surround structure and,
• wherein at least one of the projections is resiliently movable relative to its corresponding groove and is engaged with said corresponding groove, which enables the body to be temporarily engaged and moved to the desired vertical position relative to the door surround structure and temporarily retained in position prior to final fixing of the striker plate to the door surround structure, the engagement between the first and second oppositely disposed projections and the corresponding oppositely positioned grooves avoiding any requirement of an installer holding the striker plate in position as the striker plate is finally fixed in the desired vertical position,
• b. inserting the selected striker plate in the recess in the corresponding door surround structure so that the projections are engaged with and biased against the corresponding oppositely positioned grooves in the door surround structure so that the striker plate is permanently fixed in the desired lateral position by the projections and temporarily retained in a vertical position by the projections, the projections permitting vertical slidable motion of the selected striker plate with respect to the door surround structure;
• c. adjusting the vertical position of the striker plate by sliding the striker plate to the desired vertical position, and
• d. final fixing the striker plate to the door surround structure to prevent further vertical motion of the striker plate relative to the door surround structure.
