Abstract
A door closing mechanism for pulling a door tight to a frame to which the door is mounted comprises a latch arm assembly having a latch arm pivotally secured to a panel of the door and pivotable between a first, open position and a second, latched position. An activating mechanism is operably connected to the latch arm assembly by a connecting apparatus and actuates the latch arm between its first and second positions. A latch member is secured to the jamb in which the door is mounted and is arranged and constructed so that when the latch arm is moved into its second, closed position, the latch arm engages the latch member and exerts force upon the latch member in a direction substantially normal to the plane of the door so as to cause the door to contact the door frame over substantially its entire height.

A door closing mechanism for pulling a door tight to a frame to which the door is mounted comprising:
- a latch arm assembly having an offset bar pivotally secured to a panel of said door and a latch arm secured to the distal end of the said offset bar, the latch arm assembly being pivotable between a first, open position and a second, latched position;
- a latch member secured to a jamb in which said door is mounted adjacent to said latch arm assembly;
- an activating mechanism operably connected to said latch arm assembly by a connecting means to actuate said latch arm between said first and second positions, the activating mechanism itself comprising a lever pivotally secured to said door panel and a connecting means operatively connecting said lever to a distal tip of said latch arm so that when said lever is moved from a first, open position to a second, closed position, said latch arm is rotated from its first, open position to its second, closed position.
A door closing mechanism for pulling a door tight to a frame to which the door is mounted comprising:
- a latch arm assembly having a latch arm pivotally secured to a panel of said door and pivotable between a first, open position and a second, latched position;
- a latch member secured to said jamb in which said door is mounted adjacent to said latch arm assembly;
- an activating mechanism operably connected to said latch arm assembly by a connecting means to actuate said latch arm between said first and second positions, the activating mechanism itself comprising a lever pivotally secured to said door panel and a connecting means operatively connecting said lever to a distal tip of said latch arm so that when said lever is moved from a first, open position to a second, closed position, said latch arm is rotated from its first, open position to its second, closed position;
- and,
- the latch arm assembly being arranged and constructed so that when the latch arm is moved into its second, closed position, the latch arm engages the latch member and exerts force upon the latch member in a direction substantially normal to the plane of the door so as to cause the door to contact the door frame over substantially its entire height.
A door closing mechanism for pulling a door tight to a frame to which the door is mounted comprising:
- a latch arm assembly having an offset bar being pivotally mounted at one end upon a pivot pin affixed to a bracket secured to a panel of said door and one end of a latch arm being secured to the distal end of said offset bar, said latch arm pivotable between a first, open position and a second, latched position,
- a latch member secured to a jamb in which said door is mounted adjacent to said latch arm assembly so that the latch arm of the latch arm assembly may engage the latch member;
- and
- an actuation mechanism operably connected to said latch arm assembly by a first connecting means coupled to said latch arm of said latch arm assembly distal to a pivot pin on which said latch arm assembly pivots, said actuation mechanism being capable of moving said latch arm between said first and second positions, wherein said door is connected to said latch arm assembly by a second connecting means coupled to said latch arm of said latch arm assembly distal to said pivot pin on which said latch arm assembly pivots.
