Multipoint lock for sliding patio door

A multipoint lock for securing a door in a closed position relative to a door frame, comprising:

• a tie bar securable to a door for selected movement in a longitudinal direction between a securing position and a disengaged position;
• first and second keepers securable to a door frame with a selected spacing therebetween;
• first and second latch members selectively engageable with said first and second keepers with a door in a closed position;
• and
• means for securing said first and second latch members to said tie bar with said selected spacing therebetween, said securing means further including means for adjustably securing said latch members laterally relative to the longitudinal direction of movement of said tie bar, wherein said securing means for each of said latch members includes
• a fixed screw hole in said tie bar,
• a screw having a shaft threaded into said tie bar screw hole, said screw further having a head and tool-engageable means for turning said screw to locate said screw head in a selected position, and
• a slot in said latch member receiving said screw head, whereby said latch member is selectively securable in a lateral direction relative the longitudinal direction of movement of said tie bar by the selected position of said head.

A multipoint lock for securing a door in a closed position relative to a door frame, comprising:

• a metal face plate securable over a groove in a side of a door;
• a metal tie bar longitudinally movable in a groove in a side of a door between a securing position and a disengaged position;
• first and second latch members secured to said tie bar;
• and
• means for securing said tie bar to said metal face plate at at least two locations to allow longitudinal movement of said tie bar relative to said plate, said securing means at each of said at least two locations including
• a plastic spacer between said face plate and said tie bar, said plastic spacer preventing metal to metal contact between said face plate and said tie bar and including an opening therethrough,
• a securing member extending through openings in said face plate and said tie bar and through said spacer opening, said securing member having heads at opposite ends thereof larger than the face plate and tie bar openings to secure the face plate, spacer, and tie bar therebetween.

A multipoint lock for securing a door in a closed position relative to a door frame, comprising:

• a longitudinal tie bar having opposite ends and securable to a door for selected longitudinal movement between a securing position and a disengaged position, said tie bar having means on both ends for securing to a latch member, said securing means comprising a securing hook at each end of said tie bar;
• means for selectively moving said tie bar between said securing position and said disengaged position;
• and
• first and second latch members each having means on one end for cooperating with said tie bar securing means to secure said first and second latch members to said tie bar opposite ends for longitudinal movement with said tie bar, said latch member securing means comprising interengaging hooks cooperable with the tie bar securing hooks.

A control for a multipoint lock for securing a door in a closed position relative to a door frame, comprising:

• a face plate securable over a groove in a side of a door;
• a tie bar longitudinally movable in a groove in a side of a door between a securing position and a disengaged position, said tie bar having a first selected thickness and first and second latch members secured thereon:
• means for securing said tie bar to said face plate in at least two locations to allow longitudinal movement of said tie bar relative to said plate, said securing means at each of said at least two locations including a longitudinal slot in said tie bar and a securing member having a longitudinal axis that is generally parallel with respect to the tie bar, each of said securing members having
• a body member extending substantially between opposite longitudinal ends of each securing member, said securing member body member being received in said tie bar longitudinal slot with parallel longitudinal sides cooperating with said tie bar longitudinal slot to guide said tie bar for longitudinal movement, and
• first and second fasteners at opposite longitudinal ends of each of said securing members and secured to said face plate with each of said body members having its parallel longitudinal sides substantially parallel to the direction of longitudinal movement of said tie bar relative to said face plate.

A releasable multipoint latch for securing a door in a closed position relative to a door frame, comprising:

• a tie bar securable to a door for selected longitudinal vertical movement between a securing position and a disengaged position, said tie bar having first and second latch members secured thereon with a selected spacing therebetween;
• a pivot link pivotable about a substantially horizontal axis, said link having first and second arms, said first arm being drivably engageable with said tie bar to selectively move said tie bar vertically toward its disengaged position when said pivot link is pivoted in a first direction about its horizontal axis;
• a handle member securable to a door for pivoting in a first direction about a substantially vertical axis when said handle member is pulled horizontally toward opening a door;
• means for drivably engaging said handle member with said pivot link second arm whereby pivoting of said handle member in the first direction about its vertical axis pivots said pivot link in the first direction about its horizontal axis;
• first and second keeper hooks securable to a door frame with said selected spacing therebetween;
• and
• means for biasing said tie bar toward said securing position;
• whereby with a door in a closed position relative to a door frame said first and second latch members in the securing position cooperate with said first and second keeper hooks to prevent the door from being moved from its closed position.
