Abstract
A recoil module is provided for use in toy airplanes or other suitable devices. The recoil module includes an outer shell including an outer surface and an interior cavity within the shell. A recoil spool is retained within the cavity of the shell and is supported on an elastic band that spans the interior cavity of the shell. The elastic band is held fixed at its opposed ends by the shell. A pull cord is affixed to a portion of the spool and has an end extending through the shell to the outer surface. The pull cord has a free end that can be grasped to extend the pull cord from the shell and store potential energy in the elastic band. When released, the pull cord retracts back to the interior cavity of the shell. The module shell and the recoil spool can each be constructed for easy snap together assembly. The recoil module can be installed on a toy requiring or benefitting from its use. A recoil device is also disclosed that can be integrated into a toy or other object such as a toy glider airplane.
