Refrigerator door lock with alarm
First Claim
1. A lock and alarm device for attachment to refrigerators, freezers, cabinets and the like installed in recreational-type vehicles for securing the doors of such refrigerators, freezers, cabinets and the like in which an alarm will occur when such doors are not secured and the vehicle engine is started, comprising:
- friction lock means mountable adjacent to at least one door, said means having a manually operable handle, said handle adapted to contact the front surface of the door in a first position, such contact serving to hold the door securely closed, and to clear the door in a second position allowing the door to be opened;
electrical contact means operatively connected to said handle and arranged to be in a closed position when said handle is in the second position, and to be in an open condition when said handle is in the first position; and
electrical alarm signal means connected in series with said electrical contact means and connectable to the ignition switch of the vehicle, thereby forming a series circuit consisting of the vehicle battery, said electrical contact means, said signal means, and the ignition switch;
whereby said alarm signal means is energized when said lock is in the second position at a time when the ignition switch is closed.

Abstract
A manual positive locking device for doors of refrigerators, freezers and the like that do not have positive door locks such as typically used in motor homes, the locking device having an integral switch connected to an electrical alarm and adapted to be connected to the electrical system of the vehicle such that attempting to start the vehicle with the locking device in the unlocked condition will alert the operator of the unsecured condition. A rotatable T-shaped handle is provided that can be turned to a position that holds refrigerator doors in a tightly closed condition and in such position opens the contacts of the integral switch. The handle can be turned to a position clear of the doors and in such position closes the contacts of the integral switch and thus enables the alarm circuit for initiation when the vehicle ignition switch is turned on.
