ABSTRACT:
A self locking chain device for locking a chain to a vehicle comprises an elongated cross bar having an upwardly extending arm attached to each end thereof. Each arm comprises first and second arbors which define a receiving slot for receiving a first interior link of a chain and configured in such a manner to enable two adjacent contiguous links to lock the interior link therein. Both first and second arbors are provided with cusps or projections for limiting passage of the chain link to and from the receiving slot. The first arbor also is provided with a concavity. A second contiguous or selected link, serving as a locking link, is slid over and down the first arbor and to the concavity, thereby double locking the first interior link since the opening between the cusps or projections is less than the combined diameter of the interior link and locking link. In this manner, the device effectively double locks the chain, prohibiting exit of the interior link without first removing the locking link from the first arbor.
