Multipoint lock assembly for a swinging door
First Claim
1. A door lock assembly for use in locking a swinging door, said lock assembly comprising:
- a plurality of latch pins mounted at spaced positions along a side edge of a swinging door for movement between an advanced position projecting outwardly from the door side edge, and a retracted position withdrawn substantially into the door side edge;
means for supporting said latch pins for displacement in a first direction along the door side edge concurrently with movement to said advanced position, and in a second opposite direction along the door side edge concurrently with movement to said retracted position;
actuator means for displacing said latch pins between said advanced and retracted positions, said actuator means including means for normally positioning and retaining said latch pins in said advanced positions;
trigger means responsive to movement of said latch pins to said retracted position for retaining said latch pins in said retracted position, said trigger means including means responsive to closure of the door for releasing said latch pins for return movement to said advanced position; and
a plurality of strike plates for mounting onto a door jamb in a position adjacent to the side edge of the swinging door when the door is in a closed position, said strike plates each including a ramped edge engaged by a respective one of said latch pins upon movement to said advanced position for drawing the door to a tightly closed condition.

Abstract
An improved multipoint lock assembly is provided for securing a swinging door in a tightly closed condition. The multipoint lock assembly includes a main actuator cartridge for retracting a plurality of latch pins mounted at vertically spaced positions along a free side edge of the swinging door, in response to rotational movement of indoor and outdoor lever handles. A trigger assembly retains the latch pins in a retracted position in response to lever handle rotation to open the door, and includes a trigger pin for engaging the adjacent door jamb upon door closure to release the latch pins for spring-loaded movement to an advanced position. The advanced latch pins engage ramped strike plates on the door jamb to draw in and tightly retain the closed door against the door jamb. When the latch pins are advanced, a security deadbolt on the main actuator cartridge can be thrown to positively lock the door. When the deadbolt is thrown, a panic release mechanism permits retraction of the deadbolt and latch pins in response to rotation of the indoor lever handle, but not in response to rotation of the outdoor lever handle.

16. A door lock assembly for use in locking a swinging door, said lock assembly comprising:
-
at least one latch pin mounted along a side edge of a swinging door for movement between an advanced position projecting outwardly from the door side edge, and a retracted position withdrawn substantially into the door side edge, said latch pin moving in a first direction along the door side edge concurrently with movement to said advance position, and in an opposite direction along the door side edge concurrently with movement to said retracted position; spring means for urging said latch pin normally to said advanced position; actuator means on the door operable to displace said latch pin from said advanced position to said retracted position; trigger means responsive to movement of said latch pin to the retracted position for retaining said latch pin in the retracted position, said trigger means including a trigger pin responsive to closure of the door for releasing the latch pin for spring-loaded return movement to said advanced position; and a strike plate for mounting onto a door jamb in a position adjacent to the door side edge when the door is closed, said strike plate having a ramped edge engaged by said latch pin upon movement of said latch pin to the advanced position for drawing the door to a tightly closed position. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24)

25. A door lock assembly for use in locking a swinging door, said lock assembly comprising:
-
a plurality of latch pin units mounted at spaced positions along a side edge of a swinging door, each of said latch pin units including a latch pin movable between an advanced position projecting outwardly from the door side edge and a retracted position withdrawn substantially into the door side edge, and cam means movable back and forth in a direction along the door side edge for displacing said latch pin in a first direction along the door side edge concurrently with movement to said advanced position and in a second opposite direction along the door side edge concurrently with movement to said retracted position; an elongated drive bar extending generally along the door side edge for movement back and forth in a direction along the door side edge, said drive bar being coupled to said cam means for moving said latch pins of said latch pin units between said advanced and retracted positions; actuator means including a drive linkage and indoor and outdoor handle means for operating said drive linkage to shift said drive bar in a first direction along the door side edge to move said latch pins from said advanced position to said retracted position; spring means for normally urging said drive bar to shift in a second direction along the door side edge to move said latch pins from said retracted position to said advanced position; trigger means responsive to movement of said latch pins to said retracted position for retaining said latch pins at said retracted position, said trigger means including means responsive to movement of the door to a closed position to release said latch pins for spring-loaded movement from said retracted position to said advanced position; and a plurality of strike plates mounted on a door jamb adjacent to the door side when the door is closed, each of said strike plates being aligned generally with an associated one of said latch pins and including a ramped edge for engagement by said associated latch pin to draw the door side edge to a tightly closed position. - View Dependent Claims (26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39)

40. A door lock assembly for use in locking a swinging door, said lock assembly comprising:
-
at least one latch pin mounted along a side edge of a swinging door for movement between an advanced position projecting outwardly from the door side edge, and a retracted position withdrawn substantially into the door side edge; actuator means for displacing said latch pin between said advanced and retracted positions, said actuator means including means for normally positioning and retaining said latch pin in said advanced position; a deadbolt movable between a thrown position protruding from the door side edge and a retracted position withdrawn substantially into the door side edge; means for displacing said deadbolt between said thrown and retracted positions; said actuator means further including indoor and outdoor rotatable handle means disposed respectively at indoor and outdoor sides of the swinging door, and a drive linkage coupled between said indoor and outdoor handle means and said latch pin and operable for displacing said latch pin between said advanced and retracted positions in response to rotation of either one of said indoor and outdoor handle means; means for uncoupling said indoor and outdoor handle means from said drive linkage when said deadbolt is in the thrown position, whereby rotation of either one of said indoor and outdoor handle means when said deadbolt is in the thrown position is ineffective to operate said drive linkage to displace said latch pin between said advanced and retracted positions; a panic release mechanism responsive to rotation of said indoor handle means when said deadbolt is in the thrown position to displace said deadbolt to said retracted position and to displace said latch pin to said retracted position; and trigger means responsive to movement of said latch pin to said retracted position for retaining said latch pin in said retracted position, said trigger means further including means responsive to closure of the swinging door for releasing said latch pin for return movement to said advanced position. - View Dependent Claims (41, 42)
