发明名称 Playset having a retractable track section
摘要 A playset for use with a wheeled toy vehicle includes a flexible first track section defining a first part of a path for the toy vehicle, a rigid and looped second track section defining a second part of the path, and a cavity formed in the second track section sized to permit the first track section to be shifted between an extended position and a retracted position. The first part of the path and the second part of the path are aligned when the first track section is in the extended position, and at least a major portion of the first track section is disposed within the cavity of the second track section when the first track section is in the retracted position.
