Touch pad lock assembly

A lock assembly adapted for mounting on an associated closure and the like of the type that can be moved between an open position and a closed position and an opening in the closure extending between an exterior and an interior surface of the closure, the lock assembly comprising:

• a housing having an exterior plate juxtaposed against the exterior surface of the closure and an interior plate juxtaposed against the interior surface of the closure, the exterior and interior plates attached one to the other between the exterior and interior surface of the closure;
• a handle pivotally mounted upon the exterior plate of the housing for rotation between a retracted position and an extended position;
• a latch operably connected with the handle, and configured such that when the handle is in the retracted position, the latch is in a latched position, wherein the closure cannot be unintentionally shifted from the closed position, and when the handle is in the extended position, the latch is in an unlatched position, wherein the closure is free to be moved from the closed position to the open position;
• a key lock mounted on the exterior plate of the housing, where the key lock has a locked and an unlocked position;
• a lock cam rotatably mounted in the housing and operably connected with the key lock for rotation therewith, the lock cam having a crank arm;
• a first link operably connected with the crank arm;
• a deadbolt lock movably mounted in the housing for shifting between a locked position, wherein the closure is positively retained in the closed position, and an unlocked position, wherein the closure is free to be shifted between the open and closed positions;
• the deadbolt lock being operably connected with the first link;
• a motor operatively connected with the first link;
• an electronic touchpad mounted on an exterior portion of the housing being operatively connected with the motor, whereby entry of a preselected numerical code actuates the motor and contemporaneously shifts the deadbolt lock between the locked and unlocked positions;
• and
• water diversion channels provided on an internal surface of the exterior plate to divert water between the exterior plate and the interior plate away from the motor.

A lock assembly adapted for mounting adjacent an associated closure of the type that can be shifted between an open position and a closed position, comprising:

• a housing;
• an external handle pivotally mounted in an exterior portion of the housing for rotation between a retracted position and an extended position;
• a latch operably connected with the external handle and configured such that when the external handle is in the retracted position, the latch is in a latched position, wherein the closure cannot be unintentionally shifted from the closed position, and when the external handle is in the extended position, the latch is in an unlatched position, wherein the closure is free to be shifted from the closed position to the open position;
• a key lock mounted on the exterior portion of the housing, where the key lock has a locked and an unlocked position;
• a lock cam rotatably mounted in the housing and operably connected with the key lock for rotation therewith, the lock cam having a lock cam crank arm;
• a first link operably connected with the lock cam crank arm;
• a deadbolt lock movably mounted in the housing for shifting between a locked position, wherein the closure is positively retained in the closed position, and an unlocked position, wherein the closure is free to be shifted between the open and closed positions;
• the deadbolt lock being operably connected with the first link;
• a motor having a locked and unlocked position operatively connected with the first link;
• a motor crank arm operably connected with the first link and the motor to shift the deadbolt lock between the locked and unlocked positions;
• a second link operably connected with the motor crank arm and the deadbolt lock, wherein rotation of the lock cam operates through the second link to rotate the motor crank arm and rotation of the motor crank arm operates through the first link to shift the deadbolt lock between the locked and unlocked positions;
• and
• an electronic touchpad mounted on the exterior portion of the housing being operatively connected with the motor, whereby entry of a preselected numerical code actuates the motor and contemporaneously shifts the deadbolt lock between the locked and unlocked positions, wherein actuation of the motor operates through the second link to rotate the lock cam and through the first link to shift the deadbolt lock between the locked and unlocked positions.
