STORAGE SYSTEM

This invention relates to a storage system, and in particular though not exclusively to a system for the storage of generally planar items such as optical discs 5 and the like, and in particular to a mechanism for retaining in place optical disc holding sleeves within an optical disc container. The invention further relates to an optical disc holding container provided with such a retaining mechanism Optical discs, such as audio compact discs (CDs), video compact discs (VCDs), digital versatile discs (DVDs) and CD-ROMs have achieved widespread 10 popularity in both professional and business environments, and also for domestic uses. Audio CDs are now the preferred form of recording for music, while VCDs and DVDs are becoming increasingly popular for video recordings. Furthermore t)VDa and CD-ROMs are now very frequently used for software and computer-readable data in view of their high data storage capacity and their high reliability.

Some problems remain, however, with the storage of optical discs. While optical discs are fairly robust, they can be damaged and need to be protected when not in use. Conventionally optical discs are sold with each optical disc being received within a single plastics case (often called a "jewel case"). Such cases are effective to protect the discs, but they are usually several times thicker than the disc itself and thus 20 when a number of discs and associated jewel cases are involved, they start to take up a significant amount of space. This can be a problem, for example, when storing discs on a shelf, or indeed when it is desired to carry a number of discs when travelling.

In view of these difficulties a number of alternative storage arrangements have been proposed. Often such arrangements involve the use of plastic sleeves for 25 receiving the discs, with the sleeves then being retained within some form of outer housing. For example, one well- known system is arranged in the manner of a book or album, with "pages" bearing plastic sleeves for receiving the discs all held within a relatively hard outer cover. i this way such a system is similar to a photograph album. This type of system is quite effective for holding a large number of discs, but if one is only concerned with holding a smaller number of discs, then such "albums" 5 are too large and would involve too much wasted space. Furthermore such "albums" are not very flexible in terms of the nunmber of discs that they can store, which is usually fixed by the number of pages and the number of discs per page.

Another known storage mechanism includes individual plastics sleeves for holding one or two discs and which can be removeably inserted into an outer casing lo or receptacle. One such known design includes square sleeves adapted to hold two discs separated by an inner sheet. One edge of the sleeve is formed with a relatively wide plastics edging in which is formed two L-shaped cut-out portions for engaging a receiving mechanism formed on the "spine" of the outer casing which is formed in the manner of the front and back covers of i book. The diso receiving sleeves are 15 therefore similar to pages of a book that can be removed and replaced.

Other examples of known storage systems are to be found in EP0949628A, US6012575, tJS5495953, US4327831 and FR2744555.

US 5495953, for example, discloses a system for storage of CDs and the like while they are still received within their jewel cases. in this example each jewel case 20 is received within a holder element that in turn is attached via a pivot journal to a profiled section. Such a system does allow a number of CD jewel cases to be stored, and allows the jewel cases to be easily inspected so that a user can identify a desired disc. However, since the discs are retained within the jewel cases, and the holder elements are Inevitably wider than the jewel cases, this system certainly does not help 25 with the space problems encountered when storing large numbers of discs. Indeed a system of this type would aggravate the space problems. FR2744555A describes a similar system except that in this document the holder elements are formed with elongate projections of a circular cross-section and which may be received within corresponding circular grooves spaced at regular angular intervals around a column.

Again while this system allows CD jewel cases to be stored and easily Inspected, it certainly does not solve any space-related storage problems.

US 4327831 is an older system designed in particular for storing gramophone discs where it is essential to ensure that the playing surface of the disc avoids contact with any surface of the storage means so as to prevent damage. In US 4327831 a 10 relatively container structure is described tat can hold a gramophone record without the playing surface contacting the container. The container is formed with a protruding portion tat extends for the fill width of the container, and the protruding portion can be received by a male-female connector that allow a number of such containers to be assembled in a "book-like" manner.

None of the prior art proposals is entirely without drawbacks of one form or another, and thus it is an object of the present invention to provide another solution to the problem of providing space-efficient, simple and reliable storage of optical discs that mitigates the problems with the prior art, or which at least provides a usefiu alternative.

According to the present invention there is provided a storage system, comprising a plurality of holding means for holding items to be stored, each said holding means being provided with a T-shaped member projecting therefrom, and a receiving member for receiving said T-shaped members of said holding means.

In one embodiment the system may further comprise a container for housing 25 the items being stored and the receiving member may be provided within the container. Alternatively, however, the receiving member may be provided without any associated container, for example as part of a computer desk or other item of furniture.

Where a container is provided for housing the items, it may be formed of s upper and lower halves, with the receiving member being provided in the lower half In preferred embodiments of the invention, the items to be stored are generally planar items such as optical discs, documents, photographs or the like, and the holding means may then comprise a sleeve.

Preferably such sleeves are generally circular and the T-shaped member is 10 attached to a respective sleeve at a circumferential portion of the sleeve.

Preferably the T-shaped member comprises a neck portion extending radially from the sleeve, and a head portion that is parallel to a line tangent to the circumference of the sleeve. More preferably still the T- shaped member further comprises an arcuate portion having a radius of curvature approximately the same as is the radius of the sleeve. The sleeve may be formed of two sheets of plastics material bonded together for approximately half their circumference, and unbonded together for the remainder of their circumference. and the T-shaped member may be fixed to the sleeve at a junction between the bonded and unbonded parts of the circumference.

In a preferred arrangement the receiving member includes a vertical aperture 20 for receiving said T-shaped member, and the aperture has a width that is less than the width of a head portion of the T-shaped member, Preferably the disc container is generally circular in plan, though other shapes are also possible.

The invention also extends to a sleeve for holding an optical disc, wherein said 25 sleeve comprises a T-shaped member projecting therefrom, and wherein said T- shaped member is adapted to be received within a receiving member for storage of the optical disc.

Somne embodiments of the invention will now be described by way of example and with reference to the accompanying drawings, in which:5 Fig.1 is a plan view of a sleeve for holding an optical disc but with the Tshaped attachment member removed for the sake of clarity, Fig.2 is a plan view similar to Fig. 1 but including the attachment member, Fig.3 is a plan view of the T-shaped attachment member, Figs.4(a) and (b) are front and side views of a sleeve receiving mcmber, and 10 Fig.5 is a perspective view of one embodiment of the invention.

Referring firstly to Fig. 1, there is shown a plastics sleeve 1 for holding at least one optical disc. The sleeve 1 is formed of two circular sheets of plastics material each slightly larger than an optical disc. The sheets are bonded together around their circumference for approximately 1SO0 but are left unbonded for the remaining 180ù so 15 that a disc can be inserted into and removed from the sleeve. It will be understood that the circumferential extent that is not bonded needs to be large enough that a disc can be inserted into the sleeve and removed therefrom, but not so large that a disc would be likely to unintentionally fall out of the slceve.

In Figs. 1 and 2 the left side 2 of the sleeve as viewed in the Figures is bonded 20 together, while the right side 3 is left unbonded. While in this embodiment the sleeve is circular, that is not essential and the sleeve could for example be square or any othor convcnient shape.

Preferably the sleeve is adapted to hold two discs. This can be achieved by bonding between the two outer plastics sheet a dividing sheet made of a suitably soft 25 but strong material. The two outer plastics sheets are preferably both transparent so that the discs within can be seen. If the sleeve is designed to hold only one disc, then of course only one of the plastics sheets needs to be transparent. An aperture 4 may be provided in each plastics sheet I such that a user can contact a disc located therein to assist in removal of the disc from thc sleevc.

As shown in Fig.l, at the 12 o'clock position where the bonded and unbonded sides of the sleeve meets the sleeve 1 is formed with a small projection 5 the function of which will be seen from the following description of Figs.2 and 3. In Fig.3 there is shown a T-shaped attachment member 6 which is in the form of a generally planar piece of plastics material. Compared to the sleeves, however, this attichment member lo 6 is formed of a somewhat stiffer and slightly more rigid plastics material. In particular attachment member 6 is formed with an arcuate portion 7, and a T-shaped portion formed of neck portion 8 and head portion 9. As shown in Fig.2, the attachment member 6 is bonded to one side of the sleeve 1 at the 12 o'clock position.

The arcuate portion 7 is generally of the same radius of curvature as tlic radius of the is sleeve so that the attachment member 6 fits smoothly to the curve of the sleeve. The projecting portion S of the sleeve is positioned underneath at least a part of the neck portion 8 to provide a degree of reinforcement thereof, though this is not essential.

Thus, as shown in Fig.2, the T formed by the neck and head portions 8, 9 extends at right angles from a tangent formed at the 12 o'clock position where the bonded and 20 unbonded halves of the sleeve circumference meet. It will also be understood that Tshaped portion lies in the same plane as the sleeve.

The function of the attachment member 6 is to allow the sleeve 1 to be releasably attached to a receiving member 10 which in turn may be fitted within a larger CD) container. An example of a receiving member 10 is shown in front and side 25 views in Figs.4(a) and (b). The receiving member 10 is molded from a strong plastics material and is formed as an inverted T-shaped member with a vertical portion 11 projecting upwardly from a horizontal base portion 12. Vertical portion 11 is further formed with a vertical aperture 13, and as shown in particular in Fig.4(b) the top of the vertical portion 1I is bent towards the horizontal.

The horizontal base portion 12 of the receiving member 10 is designed to allow the receiving member 10 to be fixed to the interior of a case, box or other like receptacle for receiving a number of sleeves each housing one or more discs. To this end the basc portion 12 may be formed with two fixing holes 14 by means of which the receiving member 10 may be secured in place by any suitable manner The vertical aperture 13 formed in the vertical portion 11 of the receiving member 10 has a width that is less than that of the head portion 9 of the T-shaped attachment member 6. It will thus be understood that the receiving member 10 is able to receive and releasably hold a number of sleeves 1. A sleeve 1 may simply be attached to the receiving member 10 by turning the sleeve on its side so that the head 15 9 of the attachment member 6 may pass though the vertical aperture 13. The sleeve I is then turned back to a horizontal position so that the head 9 of the T-shaped attachment member is securely held in place with the neck portion 8 extending through the vertical aperture 13, and with the head portion 9 held on the other side of the vertical portion 11 from the sleeve 1. The sleeve can, of course, easily be removed 20 by simply reversing this sequence. Furthermore, because the vertical portion 11 bends over towards the horizontal at its free upper end, sleeves 1 cannot become accidentally detached from the receiving member 10.

As mentioned above, the receiving member 10 is adapted to be fixed to the interior of a case, box or the like that is to house the discs. Although the invention Is 25 by no means limited to this possibility, one preferred possibility, shown in Fig.5, is that the case or the like could be a generally circular box formed of two rigid halves 15. 16 hinged together by a hinge 17 and each half having a diameter just slightly greater than the sleeves 1. The receiving member 10 could then be secured to an interior side wall of the lower of the two box halves forming the case and adjacent the hinge connection of the two halves.

Another possibility, however, is that the receiving member could be formed independently of any case, box or the like. For example the receiving member could simply br provided in its own right as part of a storage system. For example. the receiving member could be formed as an integral part of a desk for storing computer 1o discs, or could be formed as part of a furniture unit. hi-fi unit, television unit or the like for storing audio CDs, VCDs or DVDs. In such a situation, the receiving member may be comparatively longer than in the example described above in which the receiving member must be located within a case. Indeed it is a particular advantage of the present invention that the same storage system can be used for storing optical i5 discs in a semi-permanent or fixed mainer in a home or office in situations where a case or box for housing the discs is not necessary, and at the same time can be used to store discs in a protective case or box, for example when travelling. By means of the common T-shaped projection and receiving member storage system, a sleeve holding one or more discs can easily be interchanged from a semi-permanent home or office 20 storage system which may not require a case or box, to a storage system incorporated within such a case or box for travelling purposes.

The slceve(s), T-shaped portion, and receiving member may of course be made of any suitable materials, and in many cases this would be a plastics material.

However, where the receiving member is to be formed as part of, for example, an item 25 of furniture as discussed above and thus where the receiving member may be more visible, it may be made of a higher quality and more aesthetically pleasing material such as wood or metal.

It will also be understood that while the invention is particularly suitable for the storage of optical discs and the like, it could also be used for the storage of other 5 items, such as documents, photographs, and credit cards. In general terns the system could in particular be used to store any form of generally planar item. However, it is also possible that the invention could be used to store non-planar items provided that thcy could be received within a sleeve, of that the sleeve were replaced by a different form of holding means adapted to hold that particular type of item but still provided 10 with the T-shaped member.
