1. A foldable frame device, comprising:
a flexible circular coil;
a spool housing mounted to the flexible circular coil:
a spool rotatably mounted within the spool housing:
a handle mounted to the spool for manually rotating the spool;
a first cord connected to both the spool and a first location on the flexible circular coil opposing the spool; and
wherein rotating the handle in a first direction causes the cord to wind around the spool into the spool housing enacting the force required to fold the flexible circular coil over itself in a predetermined manner so as to reduce overall circumference of the flexible circular coil for ease of portability.
