Crawl space storage system

USPTO Application #: 20070278916
Title: Crawl space storage system
Abstract: A crawl space storage and retrieval system is provided which allows a user to maximize the storing of items in a crawl space area and to retrieve stored items therefrom without entering the crawl space area. The storage and retrieval system includes a central hub assembly, a support assembly, and a plurality of edge rail sections. The central hub assembly is formed of a ball-bearing frame assembly disposed between a lower base member and an upper base member. A cover plate is disposed on top of the upper base member. The support assembly is formed of a plurality of platform sections in which each platform section is interconnected to other platform sections and to the upper base member. Each of the plurality of removable edge rail sections is interconnected to a corresponding one of the plurality of platform sections.

CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application is a continuation-in-part application of provisional application Ser. No. 60/809,559 filed on May 31, 2006.

BACKGROUND OF THE INVENTION

[0002] 1. Field of the Invention

[0003] This invention relates generally to rotatable storage structures for storing and retrieving stored items, and more particularly, the present invention relates to an improved crawl space storage system which includes a substantially circular interlocking platform that is capable of 360 degree rotation through the use of a ball-bearing center hub assembly.

[0004] 2. Description of the Prior Art

[0005] Generally, a person such as a homeowner accumulates many possessions over the course of a lifetime. Often times these possessions are not of immediate use, such as in the case of seasonal decorations or sentimental possessions, and require storage in order for the person to freely enjoy his living space. As time progresses and the homeowner acquires more possessions, storage space comes as a premium. For that reason, storage space is even more of a premium to the average sized family and it is essential to utilize any storage space to the maximum.

[0006] In most instances, maximizing the use of storage space is not the only goal. It is also important to store the possessions in a manner in which the possessions are easily accessible. As a result, many solutions have been attempted to maximize the use of storage spaces with the intent of convenient access to those stored items. Because access is also an important goal when storing items, people often ignore or underutilize storage space that is difficult to reach. Numerous solutions have attempted to efficiently make use of cabinet space by implementing rotatable storage devices, such as "lazy susans", within the cabinet. Other solutions have attempted to utilize storage space by including a rail system positioned under the floor level to store specially-sized containers. However, these attempts did not exploit the full use of crawl space storage areas in existing homes and in the new homes to be built.

[0007] In view of these attempts to maximize storage space, new implementations in crawl space storage systems have been developed in the prior art for the home improvement industry. As discussed above, some solutions have included the use of a rail system positioned under the floor level to store specially sized containers. Although these solutions may have performed adequately so as to maximize usage of the crawl space, these solutions only slightly increased the amount of usable space and none of the solutions considered the objective of creating a system whereby convenient access to the stored items eliminated the need to enter the crawl space areas in the existing homes and in the homes to be constructed.

[0008] Therefore, it should come as no surprise that crawl space storage systems have been developed and constructed heretofore in the prior art so as maximize the use of storage space areas. In spite of these efforts in the prior art, it would be still desirable to provide an improved crawl space storage system that utilizes a crawl space as an effective and safe storage area while eliminating the need to actually enter the crawl space.

[0009] A prior art search directed to the subject matter of this application in the U. S. Patent and Trademark Office revealed the following Letters Patent: TABLE-US-00001 3,290,104 5,244,270 5,479,867 5,601,395 5,813,736 6,202,359

[0010] The search also revealed U.S. Patent Application Publication Nos. 2005/0028481 published on Feb. 10, 2005 and 2005/0076817 published on Apr. 14, 2005, as well as the following Japanese Patent Application Publication Nos.: TABLE-US-00002 03144063 04014563 05033472 10248649 10339029 2000001980

[0011] In U.S. Pat. No. 5,813,736 to Ballew issued on Sep. 29, 1998, there is disclosed a cabinet storage device. The device comprises multiple vertical panels mounted upon a rotating platform. The entire device is designed to be installed within a cabinet. Thus, any of the vertical panels may be rotated to the front of the cabinet for access.

[0012] In U.S. Pat. No. 6,202,359 to Reed issued on Mar. 20, 2001, an under floor storage system for a building, such as a house, is disclosed. The system comprises a rail system supporting a train of serially coupled wagons. Both the rail system and wagons are appropriately sized to fit within the space below floor level. The serially coupled wagons are movable along the rail system and allow a user to access any one of the wagon's contents through a floor opening.

[0013] In U.S. Pat. No. 5,479,867 to Blevins et al. issued on Jan. 2, 1996, there is disclosed a rotary table. The rotary table includes a circular base and a top plate. Located between the circular base and the top plate is a bearing retainer, which receives a plurality of balls. Because the circular base rests on a stable flat surface, such as a floor, and the top plate rests on the bearing retainer, the top plate is able to rotate in a circular manner due to the bearing retainer.

[0014] In U.S. Patent Application No. 2005/0076817 to Boks et al. published on Apr. 14, 2005, there is disclosed a lazy susan with a pull-out shelving. The device includes a support base which is rotatably coupled to a centralized support pole, in a manner so that the support base can rotate entirely throughout a 360 degree circle. Wedge-shaped shelves are mounted onto a series of linear slides, which are also rotatable about the centralized support pole. The shelves are permitted to slide radially outward from the support base.

[0015] The remaining patents, listed above but not specifically discussed, are deemed to be only of general interest and show the state of the art in storage and retrieval systems for use in supporting items and for facilitating access to the items by a user.

[0016] None of the prior art discussed above discloses a crawl space storage system like that of the present invention which provides a substantially circular interlocking platform that is capable of 360 degree rotation through the use of a ball-bearing hub assembly, and which maximizes the storage area of a crawl space without having to enter the crawl space when accessing the stored items.

SUMMARY OF THE INVENTION

[0017] Accordingly, it is a general object of the present invention to provide an improved crawl space storage system which allows a person to utilize a crawl space as an effective and safe storage area, but yet overcomes the disadvantages of the prior art.

[0018] It is an object of the present invention to provide an improved crawl space storage system which allows a homeowner to access stored items while eliminating the need to actually enter the crawl space area.

[0019] It is another object of the present invention to provide an improved crawl space storage system which is of a durable construction, affordable in cost, and is relatively easy to be transported, assembled and operated by the average homeowner.

[0020] It is still another object of the present invention to provide a improved storage space system which includes a substantially circular interlocking platform that is capable of 360 degree rotation through the use of a ball-bearing hub assembly.

[0021] It is yet still another object of the present invention to provide an improved storage space system which has a low profile design and includes a plurality of extension sections as to produce an expandable platform.
