ABSTRACT:
An anchor incorporating an arrangement for releasing the anchor when it becomes snagged on large rocks or other objects. One embodiment includes a blocking element which is positioned in the elongated anchor body to prevent the anchor arms from moving out of a radially extending position to a position in which they extend longitudinally of the body. The blocking element is spring biased into its blocking position and has a sleeve thereon which is also spring biased to a position wherein the sleeve holds the anchor arms away from the blocking element. A sharp jerk on the anchor line causes the blocking element to move in the elongated anchor body out of blocking position releasing the anchor. Another embodiment includes a blocking element similarly positioned in an elongated anchor body. A striker element is mounted on the anchor body and connected to the anchor line and is spring biased to a position spaced from the blocking element. A sharp jerk on the anchor line causes the striker element to strike the blocking element to drive it out of blocking position releasing the anchor. A further embodiment of the invention releases the anchor by a pull of predetermined amount.
