  • Patent number: 4424643
    Abstract: An improved release mechanism for detachably connecting a secondary flight device to a toy parachute which is attached to a kite string and which is then, after traveling up the string with the wind, released from the string for free flight to the ground. The release mechanism includes a first member and a second member. The second member is shaped, contoured and dimensioned to detachably receive the first member. The toy parachute carries one of the members and the secondary flight device carries the other of the members, the members being maintained in engagement by the force of gravity acting on the secondary flight device when the toy parachute is engaging the kite string. The first member separates from the second member when the toy parachute is released from the kite string such that the secondary flight device and toy parachute separately free flight to the ground.
