DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
As a general rule, 33 inches is the maximum distance an average sized person can reach forward from their toe point onto, or across to, a shelf at a shoulder height with a minimum of bending and twisting. Additionally, 54 inches is the maximum height of a drawer that allows a user to be able to see and reach down into it. The maximum height of a shelf for most users is 68 inches from the floor. Thus, in a room with a ten-foot ceiling, approximately an additional 48 inches of vertical space immediately below the ceiling remain unused because it cannot be accessed without a ladder. Each of the following embodiments maximizes the advantages made available by the 33, 54, and 68 inch rules, while eliminating the need for a ladder. The present invention improves the safety and ease of use of additional storage areas (e.g., 4 feet directly below the ceiling). When used in a room with a ceiling between 8 and 10 feet high, this invention provides safe and easy access to approximately 50% of the storage space in an average home, office, or storage area.
A detailed description of non-limiting embodiments of the invention will now be described with reference to the drawings, in which like numerals represent like elements throughout. Through the present invention, it is possible to maximize the amount of available storage space.

The furniture system 100 includes, among others, a frame 102, an upper cabinet 104, a lower cabinet 106, a moving system 108 and a sliding system 110. The frame 102 has an upper portion for receiving the upper cabinet 104 and a lower portion for receiving the lower cabinet 106. The moving system 108 may be attached to the frame 102 and the upper cabinet 104 for moving the upper cabinet up and down within the frame 102. The sliding system 110 may be attached to the frame 102 and the lower cabinet 106 such that the lower cabinet 106 may be easily moved forward or backward with respect to the frame 102.
The frame 102, as shown in FIG. 2, includes front surfaces 112 and 114 as well as horizontal surfaces 116 and 118. The upper surface 118 of the frame 102 may be built as high as the ceiling of the room where the furniture system is located. The surfaces 116 and 118 may also be used for additional storage, if desired. If the upper surface 118 is used for additional storage, it may be built at a height lower than the height of the ceiling. To fully utilize the storage space right under the ceiling of a room, the upper surface 118 is preferably equal to or higher than 68 inches from the floor.
The frame 102 may be made from any suitable material. For example, the frame 102 may be made of wood, composite, polymers, or any other suitable materials known to those of skill in the art. As an option, the frame 102 may include interior or exterior supports to further strengthen the frame. The supports may be made from any suitable material, such as metal, wood, plastic, polymer, or the like, and may be adapted to appear as decorative features.
The front surfaces 112 and 114 may include decorative features (not shown). Additionally, the front surfaces 112 and 114 may include doors (not shown), which may be used to access the contents of the frame 102. The frame 102 may also include adaptable back surfaces (not shown), if desired.
The upper cabinet 104 and the lower cabinet 106 are shown in FIGS. 3(a)-3(c) without the frame 102. In FIG. 3(a), the upper cabinet 104 and the lower cabinet 106 are in their fully retracted position inside the frame 102 where the upper cabinet 104 rests on top of the lower cabinet 106. As shown in FIG. 3(a), the lower cabinet 106 has greater depth than the upper cabinet 104. However, the depth of the upper cabinet 104 may also be equal to or greater than that of the lower cabinet 106.

A winching system may occupy the remaining approximately 6-10 inches in a frame built to occupy a room having a 10-foot ceiling.
The respective depths of the upper and lower cabinets may be developed as desired. In one example, an upper cabinet may have a depth of approximately 10 inches if it is to be used as a bookcase. Alternatively, if the upper cabinet is to be used as a kitchen pantry, it may have a depth of 6 inches. Optionally, the lower cabinet may have a depth of approximately 33 inches.
Although the term “cabinet” is used to describe the upper and lower cabinets throughout the foregoing non-limiting description, it is important to note that these elements may be any article or type of furniture. In addition, the present invention is not limited to the articles of furniture selected. For example, the lower interior element may include a chest of drawers, while the upper cabinet may be a set of shelves. Alternative configurations include any combinations of drawers, shelves, or other furniture, including, but not limited to, desks, couches, gym equipment, cabinets, chairs, tables, entertainment centers, as well as all articles of furniture known to those skilled in the art.
The present invention may also include, as an optional feature, an alarm system to indicate any number of undesirable conditions. For example, the alarm system may be configured to warn that an obstruction is blocking the upper cabinet from ascending or descending. The obstruction may be a person's hand, the lower cabinet, or anything else in the way of the upper cabinet. The alarm system may also be configured to warn that the descent or ascent of the upper cabinet is not operating properly. Of course, these conditions are merely examples and any condition within the knowledge of one of skill in the art may be included.
Although the illustrated non-limiting embodiments do not show cabinet doors as a front part of the frame, doors or any decorative furniture elements may be included as desired. For example, any of frames 816, 818, and 832 in FIG. 8 may include a front door or doors as an aspect of the system. In an embodiment where the lower cabinet has an equal depth to the upper cabinet, a single door may be used to cover a front of these frames. Alternatively, any combination of any different number of doors may be used as desired. Other decorative features, such as glass covers, may also be used if desired.
Additional advantages and modifications will readily occur to those skilled in the art. Therefore, the invention in its broader aspects is not limited to the specific details and representative embodiments shown and described herein. Accordingly, various modifications may be made without departing from the spirit or scope of the general inventive concept as defined by the appended claims and their equivalents.
