Abstract
A fixation releasing device by which a buoyant body and a weight may be securely fixed and the fixed state between the buoyant body and the weight may be readily released, using a simple structure. The fixation releasing device is made from a buoyant body, a weight, and a connection designed to connect the buoyant body and weight. The connection device has a connection structure made from a closed loop member, rotation arms, and connection members. A connection member is engaged with each rotation arm, and rotation of each rotation arm is restrained by the closed loop member, thereby fixing the buoyant body. To release the buoyant body, a trigger mechanism provided at the closed loop member is operated to fusion cut the closed loop member. Then, each rotation arm is rotated, and then the connection member comes out of each rotation arm, thereby releasing the buoyant body.
