Abstract
A storage rack for thin flat objects such as CD's, DVD's and the like has multi-lobe “flower-like” pieces which may be stacked for rotation or non-rotation relative to each other. Each flower typically comprises three radially-directed lobes. Each lobe is divided into an outer portion to support an object, and a smaller inner portion for exerting downward pressure against the flat object and hold it in place. The lobes are positioned so that adjacent levels of lobes are radially displaced for viewing objects on underlying lobes.
Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The invention relates to apparatus for holding flat articles. More particularly, the invention pertains to apparatus for holding and presenting flat articles for use in a working environment.




2. State of the Art




The proliferation of electronic equipment has led to a variety of flat non-covered electronic media devices such as the compact disk (CD), digital video disk (DVD), and other thin devices. Such storage devices are useful for the storage, installation and play of computer software as well as audio, video and audio/video programs such as music, DVD movies, and games, for example. In this document, all of these devices will be simply designated as compact disks (CD's).




Traditionally, CD's are for the most part sold in so-called “plastic jewel boxes” which protect the CD when ;not in use. The jewel box contains an inner clamp which fits into the center hole of a CD to hold it in place, and includes a hinged cover which snaps shut. Typically, the jewel box contains a front label and printed material relating to the CD.




The conventional jewel box has a thickness dimension of about 10-11 mm,which is considerably greater than the 1 mm CD thickness. While most conventional jewel cases are designed to hold one CD, some are capable of holding 2 disks. Jewel boxes of significantly reduced thickness are now available, and have a thickness dimension of about 3-5mm.




To remove a CD from a jewel box, the hinged cover must be opened, and the inner clamp depressed while pulling the CD upward at its edges.




Some CD's are packaged in paper or cardboard containers of typically thin cross-section, or simply placed in paper sleeves.




Typically, both a CD and its package have an identifying label on the face thereof, and if the thickness of the container is sufficient, small lettering identifying the CD may be placed on an edge (spine) of the container. Thus, each CD package is specific to a particular CD, and placement of a CD into a package removes it from view. If a CD is mis-filed, it may be necessary to open each package (e.g. jewel box) until the lost CD is found.




While jewel boxes provide a measure of protection for CD's, the thin plastic walls, the cover hinge, and the inner clamp of such containers may easily crack or break off, particularly in repeated opening/closing of the box. Broken jewel boxes may be unusable, and may have sharp edges which may cut a user's finger. Damaged jewel boxes are typically discarded. In addition, the wide variety of jewel box dimensions (in particular, the thickness) makes it difficult or impossible to file jewel boxes of all sizes in a single storage container.




The CD collection of a user may be extensive, requiring a substantial storage space. Various approaches to disk storage may be found in the art. Prominent among these are various shelves, racks, and cases for holding a substantial number of disks in the jewel boxes, and albums containing pages with plastic inserts into which bare CDs may be inserted. The jewel boxes are typically stored in a stacked arrangement, making recognition of a particular desired jewel box difficult, and the albums quickly become too thick to handle. Often, only the front-most CD in the stack is visibly identifiable. Furthermore, the size of jewel box which is accommodated by a stacked storage rack is typically limited.




In practice, the task of removing CD's from the jewel boxes, keeping track of the empty jewel boxes, and replacing CD's in the correct jewel boxes when finished is very inconvenient. As a result, the user typically places the CD's on a convenient surface after use, not refiling them in their respective Jewel boxes until later, if ever. This is particularly so if the CD's are to be reused in the near future. Moreover, a user generally will seek to utilize his computer time, music set-up time, or DVD set-up time most efficiently, not wishing to spend time manually searching for jewel boxes, removing and placing disks in the correct box, refiling the box in a storage rack, and the like. The result is disorganized CD collections, cluttered work areas, placement of CD's on rough scratch-inducing surfaces, and wasted user time. As is well known, a scratch on the working surface of a CD will render some of the encrypted data unreadable by the laser beam of the electronic reader, resulting in a CD “skip” during play.




Various albums and cases for storing bare (unboxed) CD's are available. Such containers have the same general disadvantages as storage in jewel boxes and the like. For example, album-type storage apparatus typically have special clear plastic pages with tightly fitting pockets for storing CD's. Generally, one side of the CD may be viewed. Typically, each page contains an envelope(s) for storing 1, 2, or 4 CD's per side. A user must leaf through the album until the desired CD is located. Some storage albums incorporate closures of each pocket, typically comprising zippers, VELCRO closures, and the like. In addition, a user may place the CD liner notes or cover art inside the envelope so that each CD has its own specific envelope. If a CD is inserted in the wrong envelope, additional work is required to find it later. In summary, the task of locating, removing and replacing CD's in an album is sufficiently time-consuming so that it may not be used as intended.




Inasmuch as currently available CD storage racks, cases, albums and the like have features which encourage their non-use or limited use during actual application of CD's, an apparatus is needed for interim placement of CD's being used at a computer work station, home CD/DVD player or the like, wherein media disks may be positioned for ready identification, selection, removal for use and temporarily storage prior to returning to more permanent storage.




SUMMARY OF THE INVENTION




The invention comprises a rack or holder for short term storage and use of “bare” media disks and similar thin planar devices. Disks may be inserted and removed quickly by light finger pressure along the disk edge, making the rack very advantageous where disks are used repeatedly for short time periods. The rack is equally usable with enclosed media disks such as 3½ inch “floppies”, for example. The rack may be used for storage of any relatively rigid material with a thin cross-section.




The rack of the invention takes up little space, yet each of the disks in the rack is readily identified without disk removal, album page turning, or similar manipulation. A disk may be placed in any unoccupied position of the rack, with a sufficient portion of the disk's front face visible for identification.




The rack of the invention includes one or more “flower pieces”, each comprising a plurality (typically three) lobes spaced equilaterally about a center axis of the rack. Each lobe includes an outer portion and a separate inner portion spaced upwardly from the outer portion. A media disk, etc. may be inserted and held between the inner and outer portions of the lobe. Each lobe is intended to accept a single disk or other item. The storage capacity of the rack is customizable by the addition or subtraction of modular components.

DETAILED DESCRIPTION OF THE ILLUSTRATED EMBODIMENTS




As shown in

FIG. 2

, a conventional CD


40


A has a central hole


42


, a labeled surface


50


, an active (recordable) side


44


, and an outer edge


54


. Normally, a CD


40


A is manually handled by placing fingers on opposite edges


54


, or by placing a finger in central hole


42


and an outer edge


54


, or by placing fingers on the labeled surface


50


and active surface


44


, near edge


54


. As written herein, the invention will be directed to storage and presentation of CD's


40


A, but it will be understood that the rack may be useful for storage of any thin object capable of being held therein.




Referring now to

FIG. 1

of the drawings, a side view of a first embodiment of an exemplary storage rack


10


of the invention is shown with a portion in cross-section. Rack


10


is shown with a central axis


30


of rotation about which one or more “flower” pieces


12


A and


12


B may be rotated. The storage rack


10


holds a plurality of generally that, thin objects


40


such as media disks (CD's arid DVD's


40


A, computer floppies) and other objects (not shown in FIG.


1


). The figure shows the primary components for a modular rack


10


of two flower pieces


12


, but the rack may be varied to have any desired capacity by varying the number of rack components. The rack


10


may be made in a modular form whereby a user can vary the capacity to suit a particular need.




The components of storage rack


10


comprise one or more “flower pieces”


12


, a lower base


14


, and one or more modular stem members


16


for supporti vely joining a flower piece


12


to another flower piece. Each flower piece


12


may be independently rotated about a central axis


30


which passes through the flower piece(s)


12


, stem members


16


and base


14


. A top cap


18


or stem member


16


may be inserted in the uppermost flower piece


12


as shown.




As illustrated in

FIG. 1

, an exemplary lower base


14


supports the other components


12


,


16


, and


18


which comprise the rack


10


. Lower base


14


is shown with an integral cylindrical base stem


20


which is insertable into an axial aperture


22


of a lower flower piece


12


B. The flower piece


12


B is rotatable about the base stem


20


. The base


14


itself may be of any shape, and may be hollow or solid. As shown, it is mountable on a flat object such as a desk or table. The base


14


may also be configured to be attachable to a wall, desk, computer monitor, or other object.




Each stem member


16


is shown as a cylindrical shaft with a stop portion


24


of enlarged diameter for proper spacing upon insertion into the axial apertures


22


of the flower pieces


12


. The stem member(s)


16


and axial apertures


22


of the flower pieces


12


are sized to permit easy rotation therebetween about central axis


30


by a user's fingers.




Each flower piece


12


has a central body


32


with disk-holding lobular members (lobes)


28


extending outwardly from the body. The number of lobes


28


is shown as three, but as few as one, or a larger number than three may be used along a circumference of a flower piece


12


. As the number of lobes


28


per flower piece


12


is increased, the overall diameter


34


of the flower pieces


12


will increase. Three lobes


28


are shown in the figures to illustrate what is believed to be a generally optimum number for most applications with standard size CD's


40


A (see FIG.


2


), in order to provide interlobular space


46


(see

FIG. 3

) for viewing the labeled top surfaces


50


of CD's on an underlying flower piece


12


B or lower level of the same flower piece, while maintaining a minimal overall rack size for placement on a desk or table, for example.




As shown in

FIG. 1

, each lobe


28


includes an outer portion


36


which is configured to support a portion of the underside of a flat thin object


40


, e.g. the active (recordable) side


44


of a CD


40


A. Thus, outer portion


36


is a lower support member for a CD


40


A. A smaller inner portion


38


of lobe


28


comprises a secondary lobe which is spaced upwardly from outer portion


36


, i.e. is an upper member generally parallel to the lower support member (outer portion


36


), and has a bending modulus by which a slight compressive force is exerted on object


40


placed in the space


52


between the outer portion


36


and the inner portion


38


. The slight compressive force holds the CD


40


A (or other item) in the lobe


28


. In the embodiment of

FIG. 1

, the inner portion


38


(inner lobe) is shown as extending outwardly to cover the central hole


42


of a CD


40


A. However, the outer portion


36


and cooperating inner portion


38


may have any shapes by which a CD


40


A may be easily inserted therebetween and held firmly, yet permitting easy removal by slight finger pressure. A range of disk thicknesses


56


may be accommodated by a given lobe


28


wherein disks of greater thickness will be subjected to slightly higher compression. For example, conventional computer disks known generally as 3½ inch “floppies” have a case thickness of about 3 mm, and are easily accommodated by a storage rack


10


designed for CD disks


40


A of about 1 mm thickness.




As shown in

FIG. 1

, the lobes


28


of a flower piece


12


may be coplanar as in the upper flower piece


12


B, or may be angled downwardly from the central axis


30


as in the lower flower piece


12


A. The angle


60


of a lobe


28


from horizontal may theoretically be as much as about 90 degrees, but preferably is less than about 60 degrees. For most desk-top applications, angle


60


is preferably between about 5 degrees and 25 degrees.





FIG. 3

is a top view depicting an example of a three-lobed flower piece


12


with a central body


32


surrounding axial aperture


22


. Each lobe


28


has an outer portion


36


and an inner portion


38


. In use, the upper surface


58


of the outer portion


36


will contact the active surface


44


of a CD


40


A.




As noted in

FIG. 3

, the axial projection of an inner portion


38


of lobe


28


is substantially entirely within the inner periphery


76


of the outer portion


36


, and separated from it laterally.




As depicted in

FIG. 3

, the upper surface


58


of outer portion


36


which will contact the active surface


44


of a CD


40


A may optionally be specially treated or coated with a non-scratch material


62


. For example, the surface


58


may be made very smooth. Alternatively, the non-scratch material


62


may comprise a soft non-scratching material such as a soft plastic, fabric, fine-filament brush, felt, rubber or the like which is applied to surface


58


.




Each of the rack components, including flower pieces


12


, lower base


14


, stem members


16


and cap


18


may be readily molded as a single unit. A wide variety of plastic materials may be used. Because of differences in modulus of bending, the lobe thickness may be varied to achieve the desired compressive force to hold a thin object


40


in the lobe


28


. Alternatively, for example, each lobe


28


may be molded separately and joined to the flower body


32


.




A single-flower embodiment of the storage rack


10


is shown in FIG.


4


. The flower piece


12


has three lobes


28


extending uniformly radially from flower body


32


about central axis


30


, and project somewhat downwardly. The inner portion


38


of each lobe


28


is raised above the level of the outer portion


36


to hold a CD


40


A or other thin object


40


therebetween. Removal of a thin object


40


is enhanced by an indent


64


in the outermost edge


48


of the inner portion


38


. This indent


64


permits access to the central hole


42


of a CD


40


A by a user's finger for the most proper disk handling procedure. The lower base


14


is configured for placement on a flat surface, e.g. desk or table.





FIGS. 5

,


6


and


7


show an embodiment of the storage rack


10


having a flower piece


12


with three lobes


28


projecting radially from the flower body


32


. In this embodiment, the inner portions


38


include a cut-out circular portion


66


which generally conforms to the central hole


42


of a fully seated CD


40


A. This cut-out portion


66


makes it easier for a distracted user to fully insert a CD in the lobe


28


(

FIG. 6

) while performing other tasks.

FIG. 7

depicts a rack


10


formed of two flower pieces


12


depicted in FIG.


5


. The rack


10


is shown with a lobe angle


60


of about 13 degrees for both flower pieces


12


. The rack is configured to provide an inter-disk space


68


(see

FIG. 6

) which enables CD's on a lower flower piece to be readily identified, inserted and removed, even when an upper flower piece is filled.




As illustrated in

FIGS. 8 and 9

, a further embodiment of a flower piece


12


contains more than one level (e.g. two axially spaced rows) of lobes


28


. In this embodiment, the lobes


28


in each three-lobe level are radially displaced from the adjacent levels of lobes


28


by 60 degrees, in ord er to identify CD's


40


A positioned on a lower level of lobes


28


between the CD's on an overlying level. Thus, the CD's are readily visible for identification, insertion and removal. Where the number of lobes


28


on a level is N, the radial displacement D of adjacent levels is 360/2N . In this figure, the upper lobes are signified by the numeral


28


A and the lower lobes by numeral


28


B. In this configuration, the two or more levels of flower pieces


12


may be rotated as a unit, although they could be structured to rotate independently of one another via independent couplings. The flower pieces are joined such that adjacent flower pieces


12


are permanently radially displaced from each other. The number of flower pieces


12


which may stacked about axis


30


may theoretically be any number but for most applications is anticipated to be no more than about six.




In addition to having indented portions


64


of the inner portions


38


of each lobe


28


, the embodiment of

FIGS. 8 and 9

includes depressed portions


70


of the outer portions


36


. The indented portion


64


and depressed portion


70


are shown as being bisected by the radial centerline


72


of the lobe


28


.





FIG. 10

depicts a lobe


28


with both an indented portion


64


and a depressed portion


70


bisected by radial lobe centerline


72


.





FIG. 11

depicts a lobe


28


with a non-scratch surface


62


on the underside


78


of the inner lobe portion


38


as well as on the outer lobe portion


36


. It is only necessary that one of the surfaces include a non-scratch surface (obviously, the surface that comes in contact with the encoded side of the CD should include the non-scratch surface).




An exemplary flower piece


12


is shown in

FIG. 12

, wherein two levels


74


of lobes


28


are shown. As shown, each level


74


of lobes


28


does not rotate independently of the other level, although they certainly could be modified to rotate independently via independent coupling connectors. The adjacent levels


74


are radially displaced by


60


degrees. In

FIG. 13

, a flower piece


12


is shown with three levels


74


of axially spaced lobes


28


. Again, the adjacent levels of lobes


28


are displaced to enhance visibility of all disks


40


A on the rack


10


.





FIG. 14

illustrates a three-lobed flower piece


12


B into which CD's


40


A have been inserted. When another flower piece


12


A underlies flower piece


12


B, as shown, a disk


40


B inserted in the lower flower piece


12


A may be readily identified, inserted and removed from the lower flower piece


12


A. The CD


40


B is visible because of the large interdisk space


68


between adjacent CD's


40


A.




In the various illustrated embodiments of the storage rack, and obvious equivalents thereof, a storage rack is shown which enables quick, easy, convenient and ergonomically efficient storage of unboxed media disks and other thin materials. Minimal finger manipulation is required to properly store and retrieve CD's and the like. A place for temporary storage of frequently used CD's, DVD's and the like enables rapid interchange of disks and eliminates lost, misfiled and damaged disks. Use of the rack for temporary storage of disks during computer program installation, CD music recording/playback and DVD viewing operations is encouraged by the ease of operation. The rack of the invention may be used in conjunction with conventional long term storage devices, to provide a comprehensive media disk storage system.




The storage rack of the invention is versatile, in that its capacity may be modified by adding modular elements. Furthermore, it will hold a wide variety of thin objects of various sizes. The rack will hold a variety of CD's, CD-ROM's, mini-CD's, DVD's, video game disks, standard 3½ inch floppies, and other thin media packages without rack modification. The various media may be intermixed on the rack.




Where the media library is relatively limited, the storage rack of the invention may be used for permanent storage.
