| 20110017683 | Rack - A storage Rack to hold and display DVD, CD, VHS Tapes, Backup Tapes and other items. The item is held within a hanger that can be customized to fit the item held. The hanger is attached to a hub that sets on a collar which is slide unto a shaft. The shaft is attached to a base. The hangers can be of different sizes and mixed on the hub allowing a variety of items to be hung on the hub. The shaft, collar, hub, base, and hanger can be made of different materials such as plastic, metal or wood. The different materials can be mixed; shaft, collar, hub, base and hanger can be of different materials within a single assembly. The hangers hang in a vertical position to the shaft with the base being placed on a floor or attached to a ceiling. The diameter of the base, hub, collar, and shaft can be adjusted to hold more/less items within a 360° circle. The height of the shaft can be adjusted to hold more/less collars, hubs in which the hangers are attached, allowing more/less items to be held. This configuration allows for the hub to rotate around the shaft and the attached hangers to swing within the hub allowing easy visibility of both sides of the item held and the leading edge of the item to distinguish the item wanted prior to removing item from the hanger. | 01-27-2011 |
