AUTOMATIC UNLATCHING DEVICE

摘要

An automatic unlatching device can be used on cages or other enclosures for pets, horses, and other animals. In the event of a fire, a portion of the device melts, permitting the latch or lock on the cage or enclosure to open. This permits the animals to escape the danger of the fire without the need for human intervention to open the lock. A hasp formed of a meltable thermoplastic material is also disclosed.

主权项

1. A device for use on an animal cage having a door, comprising:
a meltable portion formed of a material having a melting point of less than about 140° F., the meltable portion having first and second ends; a clasp or hook attached to the first end of the meltable portion for removably attaching the device to the animal cage to prevent the door from opening; a chain attached to the second end of the meltable portion and including a portion for securing the device to the animal cage door; and a spring attached to the second end of the meltable portion, such that, when the device is attached to the animal enclosure and the meltable portion has begun to melt, the spring provides tension to increase the speed at which the meltable portion fails and permit the weight to drop through the opening and permit the door to be opened.
