  • Patent number: 6145781
    Abstract: A cable storage assembly including a storage case, a cable coil within the storage case, and an outlet opening in the side of the case through which the cable is withdrawn. A disc-shaped base is provided on the floor of the case and the cable coil is located thereon. This permits rotation of the coil and base more readily than prior art devices. The Invention also includes the provision of one or more low-friction sheets between the floor of the case and the base which will further enhance the ability of the assembly to deliver the cable easily. The sheets may be replaced by a bearing which contacts the floor at a very limited area, compared to that of the base, which aids in additional friction reduction. If it is desired to fabricate the case out of thin cardboard, plastic, or the like, a planar hard support is provided on the floor and the bearing rests thereon. In all cases, the amount of force necessary to withdraw the cable is drastically reduced.
