The present invention relates to storage devices such as those for small items such as cases for CDs and DVDs and for media disks such as compact disks, floppy disks and other storage media for computer software.
Typically a CD tower is used to store CDs in their CD cases. This device consists of an upright part with a multiplicity of angled openings along one side of the upright which are adapted to receive CD cases.
A problem with the above CD tower is that it does not have the ability to hold different sized cases or for that matter different items. Also CD towers tend to be of the same size, giving little or no flexibility.
The present invention provides an alternative storage device comprising a main support which is adapted to be used in an upright orientation, at least one cantilever means which comprises at least one lower fulcrum means and at least two upper abutment means and wherein an item of one size is able to be supported by the one lower fulcrum means and one of the upper abutment means and an item of another size is able to be supported by the one lower fulcrum means and another upper abutment means.
It is preferred that at least one of the abutment means comprises an abutment surface.
Preferably a plurality of upper abutment means comprise abutment surfaces.

A preferred embodiment of the present invention will now be described by way of example only with reference to the accompanying drawings in which:
As shown in
According to the preferred embodiment the vertical support 11 is detachably connected to the base 12.
As shown in
Each shelf 13 as shown in
Each shelf 13 curves upwardly so that its outermost tip is almost pointing vertically upwardly.
The tip 15 of the shelf 13 has a generally flat horizontal upper surface 16.
A gap is created between adjacent shelves 13 to receive an item such as a CD case.
An item such as a CD case is held within the recess 17 in a cantilever fashion by the combined action of the upper surface 16 of the shelf 13 and an upper surface located below a shelf located above.
To enable different sized items to be held in the cantilever fashion a number of different upper surfaces are provided which narrow the gap close to the body 14 of the vertical stand 11.
As shown in
The lateral length of each surface 19, 20, 21 is approximately the same and aligns with like upper surfaces 19, 20, 21 of a step formation 18 of another gap 17 above or below.
In the example shown there are three stepped upper surfaces 19, 20, 21, although there can be any desired number.
The vertical distance between upper surfaces 19 and 20, and 20 and 21 is approximately the same and is also similar to the lateral length. In this embodiment the vertical separation distance from the outermost upper surface 21 and the lower surface of the adjacent shelf 13 is larger than the vertical separation distance between adjacent upper surfaces 19 and 20, and 20 and 21. In the example given it is greater than the combined vertical height of the two vertical walls separating upper surfaces 19 and 20, and 20 and 21.
It is preferred that the lateral length of each upper surface 19, 20, 21 is sufficient to stably hold an upper edge of an item such as a CD case.
As shown in
The curved upper surface of each shelf curves downwardly from the tip 16 and around through 180° at its inner end to form a vertical wall section 22 of the vertical structure 11.
The uppermost shelf 23 shown in
As shown in
Alternatively a series of flat ledges may be provided one above another each having a different lateral length and preferably an increasing lateral length.
It is preferred that the base 12 is provided with an attachment portion which is configured like the male portion 25 and is able to couple with the female portion of any of the vertical structures 11. Alternatively a specially configured vertical structure 11 may be provided with a stronger coupling between its lowermost end and the base 12.
It should be clear from the above description that an item such as a CD case may be stored by locating one end of the CD case within the gap 17 between adjacent shelves 13. If the CD case is particularly thick then a lower part of its lower surface would be supported by the tip 16 of one of the shelves 13. Its upper inner edge would then be supported by the lower inner surface of a shelf 13 immediately above. In this way the CD case is held securely by the cantilever action provided by the bottom of the shelf 13 providing a downward force on the CD case which has a natural tendency to move upwardly at its inner end due to the weight of the overhanging outer end which extends over the fulcrum created by the tip 16 of the shelf 13.
If a smaller sized item is to be stored in the gap 17 its upper inner edge is inserted into the gap 17 so that it abuts with one of the upper surfaces 19, 20, 21 which when combined with the tip 16 allows the gap 17 to accommodate the item's vertical width.
Depending on the desired angle for supporting an item the upper surfaces may be angled differently as may the upper surface of the tip 16. The shape of the shelves 13 may also be varied and may be replaced by semi-continuous or discontinuous lateral protrusions.
In addition the curved shape may be replaced by more angular geometrical configurations.
Items may be stored in a similar fashion to that described above in the embodiment of the invention shown in
It is also noted as shown in
Although the embodiments described above show a generally planar vertical structure the invention includes other shaped vertical or inclined structures and structures which are not continuously vertical when in use.
