Abstract
A case stores CDs in a drawer which slides out from between an upper cover and a lower cover. The drawer has a handle projecting forwardly from the covers and which can be easily gripped by a user. A CD retainer in the drawer has a lip which grips a CD by snap-fitting over a side edge of the central aperture of the CD. The grip is released by the user simply pressing a push button, causing longitudinal movement of the retainer because it is on an arm extending between the button and a resilient anchorage.
Description




FIELD OF THE INVENTION




The invention relates to an apparatus for holding ( storing) a disc-like article such as a CD or a DVD.




PRIOR ART DISCUSSION




At present the most widely used apparatus of this type is a CD case comprising hinged covers, one of which supports a CD retainer. A CD is removed by removing the case from a storage rack or shelf, opening the covers, and pressing the retainer down to release the CD. Other holders have been described in the art. For example, WO87/05884 describes a case having a drawer with a locking and spring biassing arrangement. U.S. Pat. No. 5931295 also describes a case with a drawer-like sliding unit which is biassed outwardly by a spring. U.S. Pat. No. 5213209 describes a case having a drawer which is automatically locked upon closure and automatically opened when released by a single touch. WO 98/43247 describes a case having spring and locking arrangements associated with a drawer.




Thus, while various developments have been made for CD cases to provide an alternative means for inserting and removing a CD, it appears that they are quite complex because of the spring and locking arrangements. Such complexity adversely affects both manufacturing cost and reliability.




The invention is therefore directed towards providing an apparatus for holding disc-like articles which is of simpler construction and is also easier to use than the existing apparatus.

DESCRIPTION OF THE EMBODIMENTS




Referring initially to

FIG. 1

, a CD case


1


has a drawer


2


which slides to the front to reveal a stored compact disc, “CD”, and slides back in for storage as indicated by the arrows A. Any desired number of cases


1


may be stacked one on top of the other without need for any external support. This is achieved because the top of each case comprises curved ridges


4


at the front and straight ridges


7


at the back. The bottom of the case


1


comprises curved grooves


6


corresponding to the curved ridges


4


and straight grooves


7


corresponding to the straight ridges


5


. The corresponding grooves and ridges are of sufficient depth and width to grip the cases on the upper and lower sides sufficiently to allow them to stack in a stable manner. The arrangement also allows the cases to slip into registry with each other very easily with little user effort. The inter-engagement of the grooves and ridges is shown most clearly in FIG.


2


.




Referring to

FIGS. 3

to


5


, the case comprises an upper cover


10


hinged by a releasable snap-fitting hinge to a lower cover


11


. The hinge comprises a pin


30


on each side of the lower cover


11


engaging with corresponding apertures


31


in the upper cover


10


. The pins


30


in the lower cover


11


are chamfered so that, if over-stressed, the upper cover


10


slides on the chamfered face and disengages without breaking. This feature is shown in most detail in FIG.


5


(


b


).




The upper cover


10


comprises three tabs


12


on each side and a front projection


13


for retaining an information card in place. For closure, the upper cover


10


comprises apertures


14


for snap-fitting engagement with corresponding projections


15


in the lower cover


11


.




The underneath of the case


1


is shown in

FIG. 4

, in which view the grooves


6


and


7


are visible. This view also illustrates how the drawer


2


projects to the front beyond a curved front edge of the lower cover


11


, as it does beyond a curved front edge of the upper cover


10


.




The manner in which the lower cover


11


retains an information card C is shown in

FIG. 5

, which is a perspective view with the drawer


2


removed. The lower cover


11


comprises a pair of rails


16


with front stops


17


, and a set of four elongate spacedapart stops


18


along a front edge of the cover


11


. The rails


16


and the stops


17


and


18


retain an information card C, however, they also perform the function of guiding the drawer


2


in a smooth sliding action. The projections


18


engage grooves


28


in the underneath of the drawer


2


, as shown in FIG.


9


. The stops


17


prevent the drawer


2


from being pulled away from the case


2


by engagement with projections extending laterally from the drawer


2


.




Referring to

FIGS. 6

to


13


inclusive, the drawer


2


comprises a front handle


19


which projects forwardly beyond the upper and lower covers


10


and


11


. The drawer


2


also comprises a recessed circular CD seat


20


, in the center of which there is a retainer


21


and guides


22


. The retainer


21


comprises a lip


23


which snap fits over the side edge of the central aperture of a CD. The retainer is on an arm


24


extending between an actuator, namely a push-button


25


in the handle


19


, and a resilient anchorage


26


to the rear side of the retainer


21


. The resilient anchorage


26


comprises a pair of resilient arms


35


extending laterally and slightly forwardly between the arm


24


and the main body of the drawer


2


.




In operation, a number of the cases


1


may be stacked as illustrated in a simple and convenient manner without need for an external support such as a rack. A CD is placed in position by either opening the upper cover


10


or alternatively by gripping the handle


19


and sliding the drawer out. The latter action is very simple and convenient because of inter-engagement of the drawer


2


with the stops


18


and the rails


16


. These provide for a straight sliding action with little user effort.




A CD is placed in the seat


20


by pressing it down so that the retainer


21


snap-fits with the CD to retain it in position. Location of the CD is accurate because the sides of the seat


20


and the guides


22


guide it into a central position. The case


1


is then closed by either closing over the upper cover


10


or pushing the drawer


2


back into position as appropriate.




The simplest way of removing the CD is to grip the handle


19


and to pull die drawer


2


out. Gripping of the handle is facilitated by the finger grip


27


and the fact that the handle


19


projects forwardly. The user then simply presses the button


25


as shown in FIG.


13


. This causes a movement of the arm


24


towards the front as indicated by the arrows D in

FIG. 13 and 11

. This is because the resilient anchorage


26


translates a downward motion at the front of the arm into a mainly forward motion of the arm between the button


25


and the anchorage


26


. The movement of the anchorage


26


is illustrated by the interrupted lines of FIG.


11


. This movement releases the CD from the grip of the lip


23


and it “pops” up in a releasing action so that the user can lift it off the drawer.




The user may alternatively press down directly on the retainer to release the CD.




It will be appreciated that the invention provides a CD case of very simple construction as it comprises only three parts and all of the parts may be injection moulded. There is no need for additional parts such as springs. Insertion and removal of a CD is very simple because the user only needs to grip the handle


19


and pull the drawer out or push it in as appropriate. The sliding action is very smooth and requires little effort. Removal of a CD involves only pressing the button in the handle


19


and so it requires only one hand. Another advantage of the invention is that a number of the cases stack together without need for a rack. Operation of the drawer is complimentary to the stacldng features as the drawer allows a CD to be removed without removing the cases


1


above it.




The invention is not limited to the embodiments described, but may be varied in construction and detail within the scope of the claims.
