ABSTRACT:
A reel includes a reel drum enclosed within a housing comprising a first housing portion, a second housing portion, and a middle housing portion positioned therebetween. A spindle member has a first end connected to the first housing portion and a second end connected to the second housing portion. The spindle member extends through an opening in the drum so that the drum is rotatable about a spindle axis defined by the spindle member. The middle housing portion encircles the drum and has an aperture through which linear material can extend, the linear material of a type that may be spooled on the drum. The middle housing portion is rotatable about the spindle axis independently of the drum. In preferred embodiments, the reel is a cord reel and the linear material is electrical cord. In preferred embodiments, the middle housing portion is rotatable at least 360° about the spindle axis. In preferred embodiments, the drum is powered by an electric motor. In preferred embodiments, the housing is substantially spherical and the reel further comprises one or more support structures that include handles and are configured to prevent the housing from contacting a flat surface such as a floor or wall. In preferred embodiments, one or more temperature-sensitive switches are configured to shut off power to a spooled electrical cord in the event that a temperature of the reel exceeds a given threshold. In preferred embodiments, a solenoid is provided for locking the middle housing portion with respect to the first and second housing portions while the motor is rotating in a direction to spool the linear material onto the drum.
