Remotely or locally actuated refrigerator lock with temperature and humidity detection

A portable or mobile controlled temperature shipping cabinet and door lock therefor, wherein the shipping cabinet has a cabinet body in which temperature sensitive materials are to be stored and a door which closes against said cabinet body, the door lock having a body portion that mounts onto the cabinet body and a door portion that mounts onto the door to align with the body portion when the storage cabinet door is closed;

• the door portion comprising
• an enclosure that mounts to the door;
• and
• a latch strike member within said enclosure;
• the body portion comprising
• an enclosure mounting to the cabinet body;
• a latch member to engage said latch strike member;
• a motor drive mechanism for selectively moving said latch member from engagement with said latch strike member to unlock the cabinet;
• suitably programmed circuit means within the enclosure of the body portion for receiving commands specific to the door lock to actuate said motor drive to move the latch member out of engagement with said latch strike member;
• and
• a battery power supply;
• and
• a temperature monitor having a probe sensing temperature inside said cabinet, the monitor being coupled with said suitably programmed circuit means for communicating said temperature thereto;
• further comprising
• a humidity monitor having a probe sensing a humidity level inside said shipping cabinet, the monitor being coupled with said suitably programmed circuit means for communicating said humidity level thereto;
• suitable software operative to prevent the motor drive from lifting said latch member out of engagement when said the temperature detected by said temperature monitor is outside a predetermined range;
• and
• wherein said suitable software includes a provision for providing an ID code to a recipient of the shipping cabinet, wherein the ID code will identify whether the temperature detected by the temperature monitor has been outside the predetermined temperature range and whether the humidity detected by the humidity monitor has been outside a predetermined humidity range;
• and wherein the recipient returns the ID code to the shipper to obtain an opening code for the lock and if the ID code indicates that the temperature and humidity have been maintained within the respective ranges, the shipper will provide the opening code, but if the ID code indicates that the temperature or the humidity has been outside the associated range, the shipper will not provide the opening code.
