CROSS-REFFERENCE TO RELATED APPLICATIONS

[0001] This application is entitled to the benefit of Provisional Patent Application “Portable Compact Disc Storage System”, Ser. No. 60/397,731, filed 2002 Jul. 22.

BACKGROUND-FIELD OF INVENTION

[0002] The present invention relates to portable disc media carrying systems, specifically to such systems that have accordion-like structure.

BACKGROUND-DESCRIPTION OF PRIOR ART

[0003] Disc shaped digital medias, such as compact disc (CD), digital video disc (DVD) and laser disc (LD) have been in great use. The increase in the use of portable CD players, car stereos and laptop computers have made a huge demand for transporting many of these flat, circular media discs at the same time, in a portable and protective manner. Carrying many compact discs in individual plastic cases is very inconvenient.

[0004] Various attempts were made to solve these problems. A typical example of such is seen in “Sleeve type CD Case”. The invention is comprised of an outer shell and a plurality of individual compact disc sleeve pockets, mounted inside the outer shell. The sleeve pocket has a flat, double-sided envelope structure. It has openings on both sides to accommodate compact discs in each side, and a media protective sheet is inserted in the middle. A plurality of sleeve pockets are organized and assembled in a book-like fashion.

[0005] A compact disc is inserted through an opening of a sleeve pocket. The user must keep the opening of pocket, open by utilizing one of his hands, and insert the compact disc with the other hand. Then, in order to locate the compact disc the user is looking for, the user must flip sleeve pockets one by one to identify the location of objective compact disc among all others. For retrieval, the user holds the sleeve pocket with one hand to stabilize it in place and takes out the compact disc with the other hand. The same, but reverse process is required for insertion. Thus both hands are needed for the storing of compact discs. The invention provides a great method for transporting many discs in a secure, compact manner, however, the following disadvantages are clear to the users:

[0006] (a) The identification of the stored compact discs requires flipping many sleeve pockets one by one.

[0007] (b) The insertion of compact disc is awkward since it requires two hands.

[0008] (c) The retrieval of compact disc is awkward since it requires two hands.

[0009] These disadvantages become even more apparent, especially while the user is driving a car; the hands and eyes being busy maneuvering the car and a quick operation of compact disc switching is required.

[0010] As an alternative solution to this problem, there exists an expandable file system, or in other words, “accordion file”. “Accordion File” to Cook, Jr, in 1885, shows a typical example of accordion file, which is used to store documents without the awkwardness of the retrieval and insertion from flat file. The invention comprises a series of bellow envelopes, which open and stay in a fan-like fashion. By separating the outer panels at once, the openings of all the pockets are expanded while all the assembled bottom edges of the envelopes are fixed around rotational axes. Through the openings, the documents are inserted, and the contents are relatively easily seen.

[0011] “Carrier and Rack for Phonograph Records” to Hills in 1941, U.S. Pat. No. 2,261,806 is another example of accordion file used to store phonograph records. The device comprises a series of single flat envelopes assembled in a book-like fashion. When the outer panels are opened, the openings of the pockets expand simultaneously, while the bottom edges of pockets are fixed along the rotational axis of pockets. When a phonograph record is inserted, the upper half portion of it is exposed for the viewing. In open position, the inserted phonograph records are positioned in a fan-like manner, exposing the upper half portions of phonograph records. Thus the device provides a relatively easy solution for the insertion, retrieval and viewing of phonograph records.

[0012] “Accordion-like file” to Hunt in 1997, U.S. Pat. No. 5,682,992 utilizes a series of single pocket envelopes, having Z-fold structure. A sheet of compact discs protective material is folded in a zigzag manner, creating pockets of single slots on both upper and bottom sides. When the case is opened, the pockets on the corresponding side expand, and stay opened in a fan-like position with the other side of edge fixed along the rotational axis. The case must be supported by the user's hand for the operation. A compact disc can be inserted into a pocket, facing either the front or back direction since the entire pocket is made of compact disc protective material. Also, the user may unlock the bottom side of opening and store a compact disc in a pocket therein. Thus compact discs can be inserted through openings of either side, and the stored compact discs are arranged parallel to each other. The invention provides the easy insertion and storage of many compact discs, but there are some disadvantages:

[0013] (a) Upon retrieval, a compact disc the user is looking for may be located in a pocket of the upper or bottom side, thus the user has to look in both sides.

[0014] (b) A compact disc the user is looking for may be facing either the front or back direction, thus, the user has to flip the stored compact discs to see the labels.

[0015] (c) The stored compact discs are viewed vertically and the angle of pocket openings is not wide enough, thus, it is relatively hard to view the contents.

[0016] (d) The entire pockets are made of compact disc protective material, thus manufacturing cost is relatively high.

[0017] “Accordion Laser Disc Protective Holder” to Huang, in 2002 is a holder for disc shaped medias such as laser discs and compact discs. The device comprises a plurality of double-sided flat sleeve pockets and accordion folds, where the side edges of the sleeve pockets are engaged with accordion folds, with the bottom edges of sleeve pockets assembled along a rotational axis. Upon unlocking the device, the sleeve pockets are arranged and stay in a fan-like position. For storing, a compact disc is inserted into a sleeve pocket, by holding the sleeve pocket open by one hand and inserting into it by the other hand. For viewing, the compact discs stored in a fan-like position may be looked over through the openings, by tilting the direction of the openings briefly. Huang claims that the invention provides the easy glancing of the contents, however, the following disadvantages exist:

[0018] (a) The device that holds the stored compact discs in a stable fan-like position creates limitations to the viewing contents. For instance, if the device is to hold twenty compact discs and to be opened at 180 degrees, a viewing entrance can have only an 18 degrees angle. This is considered very narrow, and the user must see the labels of the stored compact discs vertically. Because carrying twenty compact discs in one case is very common these days, this is a clear disadvantage.

[0019] (b) The stable fan-like structure of the device does not provide simple one step viewing of the compact discs, since, while two compact discs are seen through one viewing entrance, the compact discs kept on the opposite sides are not seen. Thus the user must tilt the device.

[0020] (c) The device utilizes double sided flat sleeve pockets, which require two hands, thus the problems of the insertion and retrieval are present.

[0021] (d) The use of double sided flat sleeve pockets and accordion files at the same time makes the device relatively thick, less capable of carrying more discs, and more expensive to manufacture.

[0022] For these reasons, the invention is less practical in viewing, insertion and retrieval, and manufacture.

SUMMARY

[0023] In accordance with the present invention the compact disc storage device comprises a plurality of pockets defined by two identical partitions and two identical side-folds, mounted on a housing defined by a front panel, a back panel, a panel-connecting member and locking members.

OBJECTS AND ADVANTAGES

[0024] Accordingly, several objects and advantages of the present invention are:

[0025] (a) To provide pockets that create two compartment spaces for two compact discs per pocket, saving space and material.

[0026] (b) To provide pockets for compact discs which protect compact disc from scratches and dust while storing.

[0027] (c) To provide pockets for compact discs, where the openings thereof have substantially larger area, easing the viewing of the stored compact discs therethrough and giving an easy access.

[0028] (d) To provide pockets for compact discs where side portions of pockets are made of see-through material, facilitating the viewing of the stored compact discs.

DESCRIPTION OF THE PRESENT INVENTION

[0047] FIG. 1 illustrates a perspective view of compact disc storage 20 in open position with compact discs 120 inserted. The invention is comprised of a plurality of pockets 80 connected in series, securely and integrally mounted on an outer housing 30. Pocket 80 is comprised of two identical side-folds 100 and two identical partitions 110, creating a bellows structure of two compartments 90 as shown in FIG. 6. Housing 30 is comprised of front panel 40, back panel 50 and panel connecting member, where they are serially connected to each other and foldable relative to each other. Looking members 60 are mounted on front panel and back panel respectively, being able to be engaged with each other, locking housing 30 and securing the contents.

[0048] FIG. 7 illustrates a front view of side-fold 100. The shape of side-fold 100 is an elongated rectangle where the upper portion is cut as shown, and side-fold is folded in half along side-fold folding line 100a. The length of side-fold 100, extending in the horizontal direction has a predetermined distance to bring about “Slinky Effect” among pockets. The term “Slinky Effect” will be discussed in detail in the section “Operation and Function of the Invention”. The width of side-fold 100 is shorter in distance than its length. In general the length is about 15.0 cm and the width is about 4.0 cm, but they are not limited to these particularities. Side-fold 100 is made of sheet of transparent or translucent material, which includes but is not limited to polyethylene and polypropylene films.

[0049] FIG. 8 illustrates a front view of partition 110. The phantom line indicates compact disc 120 when it is stored in face-to-face relationship with partition 110. The upper portion of partition 110 resembles a portion of a circle, having a circular upper edge, and the lower portion of partition 110 resembles a portion of square. In general, partition 110 measures 13.0 cm inches in length, 9.0 cm in side edge and 9.0 cm in bottom edge. The length of partition 110 is about the same as the diameter of compact disc. Partition 110 is made of a sheet of compact disc protective material, having identical protective surfaces on both sides. The sheet of compact disc protective material includes but is not limited to nonwoven, Tyvex and sheet of silicone coated transparent film.

[0050] FIG. 6 illustrates a perspective view of pocket 80. Pocket 80 is comprised of identical, first and second side-folds 100 and identical first and second partitions 110. A side-fold side edge 100b of first side-fold 100 is integrally engaged with a partition side edge 110b of first partition 110, where the engagement means include but is not limited to heat sealing, gluing and sewing. Side-fold side edge 100b of said first side-fold 100, opposing the first engaging edge, is engaged with second partition 110 along a partition side-edge 110b of second partition 110. In the same manner, partition side edges 110b opposing the first engaging edges of first and second partitions 110 are engaged with side-fold side edges 100b of second side-fold 100 respectively. Along the engaging edges, side-folds 100 and partition 110 are flexibly folded relative to each other. Furthermore, side-folds 100 are folded in half along side-fold centerline 100a, so that side-folds 100 are sandwiched between engaging partitions 110. Accordingly, partition bottom edges 100c of facing, first and second partitions 110 are engaged with each other, and flexibly folded relative to each other. Said first and second partitions 110 and said first and second side-folds 100, having said structure, comprise pocket 80. Said pocket 80 has two compartment spaces for compact discs 120 and an expandable opening top. A compact disc 120 can reside in one of compartments 90 respectively. Compartment 90 is shown in FIG. 8, having a circular upper edge.

[0051] FIG. 1 illustrates a perspective view of a plurality of pockets 80. A plurality of pockets 80 are serially and integrally connected to each other, in a way that partition side edges 100b of same partition 100, comprising first pocket 80, are further engaged with side-fold side edges 10b of third and forth side-folds respectively. Accordingly, partition side edges of a third partition 100 are engaged with opposing side edges of third and forth side folds 100. Furthermore, a partition bottom edge 100b of third partition 110 is engaged with the bottom edge of first pocket 80. Thus, said configuration creates a second pocket 80 adjacent to first pocket 80. Note that the first and second pockets share the same partition 100 utilizing the surfaces on both sides. In this manner, a plurality of pockets are created in a spanning relationship, comprising one integrating body. Said plurality of pockets 80 connected in series are identical to each other and securely mounted on housing 30.

[0052] FIG. 1 and FIG. 2 illustrates Housing 30. Housing 30 is comprised of front panel 40, back panel 50, and locking member 60. Front panel 40 and back panel 50 are made of plastic material, having a thickness of about 1.0 mm in general, being hard enough to protect the contents of housing 30. Front panel 40 and back panel 50 are identical in shape, having elongated half-circles, so that when the body of plurality of pockets are laid down on the inner surface, fit front panel 40 and back panel 50 have enough area to accommodate a plurality of pockets. The bottom edge of front panel 40 is connected to one edge of panel connecting member 70. The other edge of panel connecting member 70 is further connected to the bottom edge of back panel 50. The connecting edges of front panel 40 and locking member 70, back panel 50 and locking member 70 are flexible, and folded relative to each other. Locking member 70 in this preferred embodiment is a zipper. The zipper is engaged along the side edges and upper edges of front panel 40 and back panel 50.

[0053] FIG. 5 illustrates the present invention in closed position. The bottom edges of a plurality of pockets 80 assembled along the axis of rotation are engaged with and secured along the centerline of panel connecting member 70. Said centerline exist to be flexibly folded along, as well as for front panel 40 and back panel 50 to be folded together. The engaging means includes but is not limited to gluing, riveting and sawing. Locking member 60 in the drawing is a zipper. The zipper is engaged along the side and top edges of front panel 40 and back panel 50, so that when the zipper is closed font panel 40 and back panel 50, become engaged through zipper. Said embodiments create an enclosed structure for a plurality of pockets 80.

Alternative Embodiments

[0054] There are many possibilities in modifying the device without getting out of the scope of the invention.

[0055] Partition 110 may have various shapes other than the one mentioned above. It may be circle, square, rectangle or any combination of these. However, they have one or more of the following functions and structures: partition 110 protects the media surface of compact disc from sliding motion against it, and dusts from the air: partition 110 divides pockets located adjacent to each other: the area of partition 110 is large enough to cover the whole area of compact disc: combined with side-folds, partition 110 secures a compact disc in place.

[0056] Accordingly, side-folds 100 may be of a different shape from the one presented above, and one or more of the following functions and structures are observed: thin sheet of flexible transparent material: it can be engaged to the partition 110. Recall that side folds 100 may or may not have the transparent property, although it is an important feature to ease the viewing of the contents.

[0057] There are many methods to secure a series of pockets 80 to housing 30 in addition to gluing to front panel 40 and back panel 50. A series of pockets may be riveted to panel-connecting member 70. The outer portions of a plurality of pockets 80 may be engaged with and mounted on the inner surfaces of front panel 40 and back panel 50. Locking member 60 may be Velcro, snap-lock or button. Locking member 60 may be anything that has one or more of the following functions and structures: upon locking the device, it holds a plurality of pockets 80 and outer panels together in closed position, securing the stored compact discs in place: upon unlocking the device, it releases a plurality of pockets 80 and outer panels to open.

Operation and Function of the Invention

[0058] From closed position as in FIG. 4, the device can be unlocked by releasing locking members 60 mounted on side and top edges of front panel 40 and back panel 50. When the present invention is unlocked, front panel 40 and back panel 50 rotationally move away from each other along the axis of rotation. The axis of rotation is located at the centerline of panel connecting member 70, which is flexibly folded along while the invention is opened. Meanwhile, pockets 80 expand in such a manner that partitions 110 rotationally move away from each other. As shown in FIG. 1, 2 and 3, the present invention is kept open at 180 degrees between front panel 40 and back panel 50 at 180 degrees on a flat surface. Accordingly, in stable open position, three pockets 80 are exposed as shown in FIG. 1 The angle between partitions is equally divided, having an angle distance of 90 degrees in the stable open position. The present invention may be kept on the user's laps while pocket entrances are exposed to the user for viewing. As shown in FIG. 5, compact disc 120 is inserted into compartment 90 through an opening exposed to the user in stable open position. The openings of compartments 90 are already expanded and large enough, so that compact disc 120 may be inserted by one hand, not requiring the other hand to hold compartment 90 open. During the insertion, the media side of compact disc 120 directly faces and becomes in touch with partition 110 and the label side is exposed to the opening. As compact disc 120 is inserted, the engaging and folded edges of partition 110 and side-folds 100 hold the disc tighter in place. Since compact disc 120 is circular in shape, the width is shorter at the tip and it becomes its maximum length at the center point. Thus, from the first phase to the last phase, the insertion is continuous and smooth. In the same manner, another compact disc 120 may be inserted into another empty open compartment 90 within the same pocket 80. In this configuration two stored compact discs 120 are seen together as shown in FIG. 1. After all the exposed compartments 90 are filled with compact discs 120, a series of pockets 80 are flipped to one side automatically by tilting to expose new empty pockets 90. Thus, all the compartments 90 may be filled with compact discs 120 by one hand operation.

[0059] FIG. 5 illustrates a perspective view of the present invention where the user's hand is operating the invention for viewing and identifying the contents. The user rests one of the panels on the ground, and tilts the other panel toward the rested panel, where a plurality of pockets 80 are overlaid on the tilted panel. Then, the outer-most pocket 80 facing the rested panel flips toward the rested panel and rests thereon. Consequently, the adjacent pocket flips, being pulled by the weight of the first pocket 80. The weight of the first pocket 80 is transferred to the second pocket 80 through flexible side-folds 100. In this manner, all the pockets 80 are flipped to one side automatically. This is what we call “Slinky Effect”, like a person is playing by transferring the slinky from one hand to another. Note that a flipping of a pocket takes place independent of another until a partition 110 of first flipped pocket 80 reaches a predetermined point. The predetermined point is determined by the length of side-folds 100, the turning radius of partition 110, the weight of partition 110, the flexibility of side-folds 100 and so on. During this process, all pockets 80 are exposed to the user at an opening angle of 90 degrees, showing the labels of compact discs 120 very clearly. In general, flipping all pockets 90 mounted on housing 30, takes place in one second. The user may change the speed of flipping by changing the tilting angle of the tilted panel. The steeper the angle is, the faster it is. If the user finds the objective compact disc 120, resting the tilted panel on the flat surface stops the flipping.

[0060] For retrieval the user may pinch the tip portion of compact disc 120, or squeeze the tip portion and the center hole of compact disc 120 with fingers. Compact disc 120 may be pulled by one hand since the openings of pockets 90 are wide enough to access by one hand. After the small, compact disc 120 is released from the securing edges of compartment, and slides along the surface of partition 110. Or compact disc 120 may be lifted off partition 110 and move through the open air inside compartment 90. Since partition 110 is made of compact disc protective material, the damage to compact disc 120 is minimized upon retrieval.

[0061] The present invention may be closed from open position by folding front panel 40 and back panel 50 toward each other. Accordingly, expanded pockets 80 positioned between front panel 40 and back panel 50, are folded together. In closed position, stored compact discs 120 are sandwiched between partitions 110 and side-folds 100 inside compartments 90. The pressure from partition 110 and side-folds 120 further secure stored compact discs 120. Compact discs 120 stored in the device are secured within each pocket 90. In this manner, stored compact discs 120 stay in place, even when the pocket openings are directed toward the center of gravity. To lock the device, locking member 60 on front panel 40 is to be engaged with locking member 60 on back panel 50. This procedure completes the operation of locking. Stored compact discs 120 are relatively safer from breaking, tearing, dust and scratches. The device allows the user to carry many compact discs 120 securely in a compact manner.
