Self-release mechanism for parcel delivery

Abstract

A self-release mechanism. The self-release mechanism includes a counter-weight, wherein the counter-weight is located on a first end of the self-release mechanism; a shaft having a top portion and a bottom portion, wherein the top portion of the shaft is coupled to the counter-weight, wherein the shaft defines a perforation, wherein the perforation is adapted to receive a cord; and a hook including a hook bend, wherein the hook is located on a second end of the self-release mechanism, wherein the hook is coupled to the bottom portion of the shaft, wherein the self-release mechanism moves to a first position when a tension is exerted on the self-release mechanism due to gravity caused by coupling of the hook to a payload via the hook bend, wherein the self-release mechanism moves to a second position when the exerted tension is released.
