Latch apparatus

A latch apparatus for mounting to a door having a first face, an edge, and a second face, the latch apparatus comprising;

• a housing adapted for mounting on the first face of the door;
• a bolt member pivotally mounted to the housing and adapted for extending and retracting beyond the edge of the door;
• a first latch handle pivotally mounted to the housing and engaging the bolt member, wherein the first latch handle is adapted for pivoting toward and away from the first face, and wherein upon pushing the first handle toward the first face of the door, the bolt retracts;
• a spring pack removably mounted in the housing and engaging the bolt and adapted for receiving a spindle;
• wherein the first handle is movable in a limited range between a first position and a second position when the spring pack is inserted in the housing, and wherein the handle is movable to a third position beyond the limited range and substantially transverse to the first position when the spring pack is removed.

A latch system adapted for mounting to a door having a first face, an edge, and a second face, the latch apparatus comprising;

• a housing having a mounting plane and adapted for mounting to a first face of the door,
• a bolt pivotally mounted to the housing and movable between an extended position and a retracted position;
• a push handle pivotally mounted to the housing and pivoting between a first position, a second position and a third position;
• a spring pack module adapted for being retained intermediate the housing and the first face of the door when assembled, wherein the spring pack module comprises a torsion spring having an axis and a camming member axially aligned with the torsion spring.

A latch system adapted for mounting to a door having a first face, an edge, and a second face, the latch apparatus comprising;

• a housing having a mounting plane and adapted for mounting to a first face of the door;
• a bolt pivotally mounted to the housing and movable between an extended position and a retracted position;
• a push handle pivotally mounted to the housing and pivoting between a first position, a second position and a third position, wherein at the first position, the handle extends away from the mounting plane, at the third position, the handle extends toward the mounting plane and at the second position the handle is intermediate the first and third positions;
• and
• a spring pack module adapted for being retained intermediate the housing and the first face of the door when assembled;
• wherein the handle is movable between the first, second and third positions prior to insertion of the spring pack and wherein the handle is restrained between the second and third position when the spring pack is inserted.

A latch apparatus for a door, the door having an outer face, an inner face and an edge, the latch apparatus comprising:

• a housing adapted for mounting to the inner face of the door;
• a bolt member pivotally pivotally mounted to the housing and adapted for extending and retracting beyond the edge of the door;
• an inner latch handle pivotally mounting to the housing and engaging the bolt member, wherein the inner latch handle is adapted for pivoting toward and away from the inner face, and wherein upon pushing the inner handle toward the inner face of the door, the bolt retracts;
• an outer latch handle adapted for rotatably mounting on the outer face of the door and having a spindle adapted to extend through the door;
• and
• a spring pack adapted for mounting on the inner face of the door and engaging the spindle for rotationally positioning the outer latch handle and for retracting the bolt member when the outer latch handle is rotated in a first direction.
