Playing field obstacle device |
摘要 |
An obstacle device for use on a playing field has a base and a frame approximating in shape the front profile of a human head and torso. The frame is coupled to the base. The frame includes a collapsible frame member that has an expanded configuration that defines an expanded frame area. The frame member also has a collapsed configuration that defines a collapsed frame area that is less than the expanded frame area. A covering material is attached to the frame so that the covering material is spread by the frame when the frame member is in the expanded configuration. |
