Safety padlock assembly

A padlock safety assembly for securing a movable door to fixed object such that the door can be locked in a closed position from exterior to the door while being openable from the interior of the door, the door having an interior face, an exterior face and a side edge, the door being movable from the closed position wherein the side edge of the door is proximate the fixed object to an open position wherein the side edge is remote from the fixed object, the fixed object having a lip, the padlock safety assembly comprising:

• a latch rod slidingly mounted to the interior face of the door proximate to the side edge, the latch rod being movable along a latch rod axis from a projected position in which it extends toward the side edge to a recessed position;
• a spring attached to the latch rod and the door for biasing the latch rod toward the projected position;
• a flexible cord attached to the latch rod and extending substantially along the latch rod axis and through the door;
• a hasp connected to the flexible cord distal to the latch rod and disposed at the exterior of the door;
• and
• means for securing the hasp in a fixed position on the exterior face of the door;
• wherein, when the door is in the closed position and the latch rod is in the projected position, the latch rod engages the lip of the fixed object and, when the hasp is displaced, the flexible cord pulls on the latch rod, overcoming the bias of the spring and disengaging the latch rod from the lip.

A padlock assembly for securing a movable door to fixed object, the door defining an interior region and an exterior region, and having a side edge, the fixed object having an abutment, the door being movable from the closed position wherein the side edge of the door is proximate the abutment, to an open position wherein the side edge is remote from the abutment, the padlock assembly comprising:

• a latch rod slidingly mounted to the door and disposed in the interior region;
• a latch tip disposed on the latch rod near the outer edge of the door, the latch rod being movable from a projected position in which the latch tip extends sufficiently to engage the abutment of the fixed object when the door is in a closed position to a recessed position in which the latch tip is displaced away from the abutment;
• means for biasing the latch rod toward the projected position;
• a flexible release cord attached to the latch rod;
• a flexible hasp cord attached to the latch rod and directed toward the door;
• an active hasp with an opening connected to the flexible hasp cord distal to the latch rod and disposed at the exterior of the door;
• and
• a stationary hasp fixedly mounted proximate to the active hasp;
• wherein, when the active hasp is displaced, the flexible hasp cord pulls on the latch rod, overcoming the bias of the biasing means and disengaging the latch rod from the abutment.

A lock assembly for securing a door to an object, the door having an a first face, a second face and an edge, the object having an abutment, the lock assembly comprising:

• means for engaging the door to the abutment disposed on the first face of the door proximate to the edge, the engaging means being movable from an engaged position in which the door is engaged to the abutment, to a released position in which the door is disengaged from the abutment;
• means for biasing the engaging means toward the engaging position;
• a flexible cord attached to the engaging means;
• an active hasp connected to the flexible cord distal to the engaging means and disposed on the second face of the door;
• and
• means for securing the active hasp in fixed position on the second face of the door when the engaging means is in the engaged position;
• wherein, when the active hasp is displaced, the flexible cord actuates the engaging means, overcoming the bias of the biasing means and displacing the engaging means toward the released position.

A padlock assembly for securing a movable door to fixed object, the door defining an interior region and an exterior region, and having a side edge, the fixed object having an abutment, the door being movable from a closed position in which the side edge is proximate to the abutment, to an open position in which the side edge is remote from the abutment, the padlock assembly comprising:

• a latch rod slidingly mounted in the door, disposed in the interior region and movable from a projected position, in which the latch rod extends sufficiently to engage the abutment of the fixed object when the door is in a closed position, to a recessed position in which the latch rod is displaced away from the abutment;
• a spring attached to the latch rod such that the latch rod is normally biased toward the projected position;
• a flexible hasp cord attached to the latch rod;
• an active hasp connected to the flexible hasp cord distal to the latch rod and disposed in the exterior region;
• and
• means for securing the active hasp in a fixed position with respect to the door;
• wherein, when the active hasp is displaced, the flexible hasp cord pulls on the latch rod, overcoming the bias of the spring and disengaging the latch rod from the abutment.
