Door strike having a kicker and an adjustable dead latch release

An actuator controlled strike for operating in conjunction with a spring latch and a dead latch of a lockset, said strike comprising:

• a) a housing having a cavity therein, said cavity configured for receiving said spring latch and said dead latch, said housing having a longitudinal length longer than a width of said housing;
• and
• b) a dead latch platform configured for making contact with said dead latch and movable in a first direction into said cavity, wherein said dead latch platform is adjustably positionable in a second direction parallel with said longitudinal length of said housing,
• wherein said housing includes a plurality of dead latch platform mounting features for receiving said dead latch platform in any two of said plurality of dead latch platform mounting features corresponding to any one of a plurality of arrangements of said spring latch and said dead latch.

An actuator controlled strike for operating in conjunction with a spring latch and a dead latch of a lockset, said strike comprising:

• a) a housing having a cavity therein, said cavity configured for receiving said spring latch and said dead latch, said housing having a longitudinal length longer than a width of said housing;
• and
• b) a dead latch platform configured for making contact with said dead latch and movable in a first direction into said cavity, wherein said dead latch platform is adjustably positionable in a second direction parallel with said longitudinal length of said housing,
• wherein said housing includes a plurality of dead latch platform mounting features configured for selectively receiving said dead latch platform.

A method for unlatching a door, having a mortise lockset including a spring latch and a dead latch, the mortise lockset cooperating with a strike, wherein the strike includes a housing having a cavity therein, a keeper disposed in said cavity, wherein said keeper is movable between a first locked position and a second unlocked position, and a dead latch platform connected to said housing and movable in a first direction into said cavity, wherein said dead latch platform is movable between a first disabling position and a second enabling position, the door unlatching method comprising the steps of:

• a) moving said dead latch platform from said first disabling position toward said second enabling position;
• b) allowing said dead latch to move in said first direction toward said cavity by said moving of said dead latch platform;
• c) enabling said unlatching of said door by said movement of said dead latch in said first direction toward said cavity;
• wherein said enabling step c) further comprises the steps of:
• d) contacting said keeper by said spring latch upon a first movement of said door away from a closed position;
• and
• e) upon further movement of said door beyond said first movement and away from said closed position, moving said keeper from said first locked position toward said second unlocked position by said spring latch to unlatch said door.

A method for unlatching a door, having a lockset including a spring latch and a dead latch, the lockset cooperating with a strike, wherein the strike includes a housing having a cavity therein, a keeper disposed in said cavity, wherein said keeper is movable between a first locked position and a second unlocked position, and a dead latch platform connected to said housing and movable in a first direction into said cavity, wherein said dead latch platform is movable between a first disabling position and a second enabling position, the door unlatching method comprising the steps of:

• a) moving said dead latch platform from said first disabling position toward said second enabling position;
• b) allowing said dead latch to move in said first direction toward said housing cavity by said moving of said dead latch platform;
• c) enabling said unlatching of said door by said movement of said dead latch in said first direction toward said housing cavity;
• wherein said enabling step c) further comprises the steps of:
• d) contacting said keeper by said spring latch upon a first movement of said door away from a closed position;
• and
• e) upon further movement of said door beyond said first movement and away from said closed position, moving said keeper from said first locked position toward said second unlocked position by said spring latch to unlatch said door.

A method of adjusting a position of a dead latch platform in a strike, wherein said strike includes a housing having a cavity, a dead latch platform mounting feature configured for selectively receiving said dead latch platform, and a longitudinal length longer than a width of said housing, wherein said dead latch platform cooperates with a dead latch of a lockset, and wherein said dead latch platform is selectively movable in a direction into said cavity, said method comprising the steps of:

• a) providing said dead latch platform with an engagement member that cooperates with said dead latch platform mounting feature;
• b) moving said dead latch platform to a position to cooperate with said dead latch;
• c) cooperating said engagement member with said dead latch platform mounting feature;
• d) securing said dead latch platform in said position so as to cooperate with said dead latch;
• and
• e) allowing said dead latch platform to selectively move in said direction into said cavity.
