This invention relates to a storage device. More particularly, it relates 
to a storage device for storing a plurality of disc-shaped articles such 
as compact disc, in closely spaced side-by-side relationship. 
BACKGROUND OF THE INVENTION 
Normally compact disc are stored in plastics cases having hinged lids. To 
play a number of tracks from a number of different discs sequentially, 
entails opening and closing a number of these cases to remove or store the 
discs. Alternatively, the discs are left lying around. 
It is an object of this invention to provide a storage device for storing, 
and retrieving, a plurality of disc-shaped articles which the Applicant 
believes will alleviate these problems at least to some extent. 
SUMMARY OF THE INVENTION 
According to the invention, there is provided a storage device for storing 
a plurality of disc-shaped articles in closely spaced vertical 
side-by-side relationship which includes a support having a support 
surface for supporting disc-shaped articles, the support including bias 
means in use to bias the articles towards rolling; and releasable 
restraining means to restrain the articles against rolling under the 
effect of the bias means. 
According to one embodiment of the invention, the support surface may 
include a sloping portion providing the bias means in the form of a 
gravity bias, to allow the articles in use to roll down the sloping 
portion on release of the restraining means. 
The support surface may include a substantially horizontal portion 
extending away from the foot of the sloping portion, a stop being provided 
at or near the end of the horizontal portion to prevent the article, in 
use, from rolling off the end of the horizontal portion of the support 
surface. 
The device may include a plurality of restraining means, one for each 
article to be stored, release of one of the restraining means in use, 
allowing the article associated with that restraining means to roll down 
the sloping portion, while the remaining articles are retained in position 
on their respective sloping portions. 
Each restraining means may include a lever having a shoe, the lever being 
biased to cause the shoe to bear frictionally against the periphery of the 
article. The shoe may have a slot to accomodate a part of the periphery of 
the disc-shaped article. 
Instead of the restraining means being in the form of levers, the device 
may include a plurality of supports, one for each article to be stored. 
The device may include a floor and a rear wall extending upwardly from the 
floor, each support being slidably mounted on the floor, and the 
restraining means may then include bias means to bias the support away 
from the rear wall of the device, the restraining means further including 
a shoulder at an upper portion of the front of the device against which a 
part of the periphery of the article abuts in use. 
According to another embodiment of the invention, the device may include a 
plurality of supports, each support including a hinged portion pivotally 
mounted on a floor of the device, and the bias means may be a spring bias 
acting between the floor and each hinged portion of the support. 
The device may include a plurality of restraining means, one for each 
article to be stored, release of one of the restraining means in use 
allowing the support associated with that article to pivot about its 
pivotal axis under the effect of the spring bias to urge the article out 
of the device. 
Each restraining means may include a lever pivotally mounted at an upper 
portion of the front of the device, the lever including a shoe which is 
biased to bear frictionally against the periphery of the device.

for each of the articles. Each guide means may include a groove which 
extends along the support, the periphery of the disc being rollably 
receivable within the groove. 
The device may include a vertical slot aligned with each groove at an upper 
portion of the front of the device to facilitate the insertion of each 
disc-shaped article into, and its removal from the device.

DETAILED DESCRIPTION OF THE DRAWINGS 
Referring to FIGS. 1 TO 3, a storage device, in accordance with the 
invention, for storing a plurality of disc-shaped articles in closely 
spaced vertical side-by-side relationship is designated generally by the 
reference numeral 10. The device 10 includes a support 12 having a support 
surface 14 for supporting disc-shaped articles 16. The support 12 
including bias means in use to bias the articles 16 towards rolling. The 
device 10 further includes releasable restraining means 18 to restrain the 
articles 16 against rolling under the effect of the bias means. 
The disc-shaped articles 16 are compact discs (referred to simply as a disc 
hereafter.) As shown in FIG. 3, each disc 16 has its own restraining means 
18. Each restraining means 18 includes a pivotally mounted lever 20 biased 
to the restraining position by means of a spring 22. Each lever 20 further 
includes a shoe 24 for engaging a part of periphery of the disc 16. 
The support surface 14 includes a sloping portion 26. the sloping portion 
26 provides the bias means in the form of a gravity bias to allow the 
discs 16 in use to roll down the sloping portion 26 on release of the 
restraining means 18. The support surface 14 further includes a 
substantially horizontal portion 28 extending from the foot 26.1 of the 
sloping portion 26. A stop 30 is provided at or near the end of the 
horizontal portion 28 to prevent the disc 16 from rolling off the end of 
the horizontal portion 28 of the support surface 14, in use. 
The horizontal portion 28 of the support surface 14 is hinged at 32 to 
serve as a door 46 to close off the front of the device 10. 
The device 10 includes guide means 34 (FIG. 3) for each of the discs 16. 
Each guide means 34 includes a groove 36 extending along the support 
surface 14, the periphery of the disc 16 being rollably receivable within 
the groove 36. A vertical slot 38, aligned with each groove 36 is provided 
below the lever 20 to facilitate the insertion of a disc 16 into, and its 
removal from the device 10. 
If other disc-shaped articles having surfaces prone to scratching, such as 
long playing records, are to be stored in the device 10, each groove 34 
and slot 36 can be lined with a non-scratch material such as velvet. 
In the embodiment shown in FIG. 2, the shoe 24 of the lever 20 includes a 
slot 40 within which the periphery of the disc 16 is receivable. 
Referring now to FIGS. 4 and 5 another embodiment of the device 10 is 
shown. With reference to FIGS. 1 TO 3, like reference numerals refer to 
like parts unless otherwise specified. 
In this embodiment a shelf 42 is provided which projects cantilever-fashion 
from a rear wall 44 of the device 10, above the storage space for the 
discs 16. The shelf 42 provides storage space for booklets (not shown) 
which are normally provided with the compact discs 16. The lever 20, 
including a slot 40 cut into its shoe 24, similar to that shown in FIG. 2 
is mounted on the shelf 42, near the free end thereof. 
The stop 30 is mounted close to the pivot axis of a hinged front portion 
forming a door 46 of the device 10. A spring biased pin 48 is mounted at 
the front of the device 10. The pin 48 has a chamfered tip 50 which 
co-operates with a sloping portion 54 of the end of the door 46. By 
pressing downwardly on the pin 48 against the action of the spring bias in 
the direction of arrow 52, the door 46 can be opened. 
Referring now to FIG. 6 yet another embodiment of a device in accordance 
with the invention is shown. With reference to the previous drawings, like 
reference numerals refer to like parts unless otherwise specified. 
In this embodiment the releasable restraining means 18 is in the form of an 
L-shaped lever 56 pivotally mounted below a top wall 58 of the device 10. 
Each lever 56 includes a slot 60 in its limb projecting vertically 
downwardly, within which part of the periphery of the disc 16 is 
receivable. The lever 56 is resiliently biased so that the limb including 
the slot projects vertically downwardly. The resilient bias of the lever 
56 is provided by means of a block of elastomeric material such as rubber 
60 mounted between a chamfered outer corner of the L-shaped lever 56 and 
the top wall 58. The lever 56 is operable by means of a button 62 
projecting through the top wall 58 of the device 10. 
A spring-biased pin 64 is mounted near the end of the front wall 58 of the 
device 10. The pin 64 has a catch 66 which co-operates with a 
complementary catch 68 of the door 46. By pressing downwardly on the pin 
64 in the direction of arrow 70, the door 46 can be opened. 
Vertical posts 37 are provided near the front of the device 10 on either 
side of each of the grooves 36 to define vertical slots, aligned with the 
grooves 36, through which the discs 16 are rollable in use. The slot 
facilitates the alignment of the disc 16 in the groove 36. 
In use, to store a disc 16 in any one of the devices 10 of the embodiment 
shown in FIGS. 1 to 6, the periphery of the disc 16 is inserted into the 
groove 36 extending along the horizontal portion 28 of the support 12. As 
the disc 16 is rolled up the sloping portion 26 of the support surface 14 
it bears against the shoe of the lever 20 or 56 and acts against the bias 
means of the lever 20 or 56 to pivot the lever out of the way. The biasing 
force causes the shoe 24 or 57 to follow the curve of the periphery of the 
disc 16. When the disc 16 abuts against the rear wall 44 of the device 10, 
the shoe 24 or 57 of the lever 20 or 56 respectively, abuts against the 
periphery of the disc thereby retaining the disc 16 in position on the 
sloping portion 26 of the support 12. The device 10 is then closed by 
pivoting the door 46 about the pivot axis of the hinge 32 in the direction 
of arrow 72, so that it is in a position shown by the dotted lines in 
FIGS. 1, 4 and 6. 
To release a disc 16 from the device 10 the door 46 is opened and the lever 
20 or the button 62 of the lever 56 is depressed. The disc 16 then simply 
rolls down the sloping portion 26 along the horizontal portion 28 under 
the action of gravity and will come to rest against the stop 30. 
Referring now to FIG. 7 a device for storing disc shaped articles in 
accordance with yet another emobodiment of the invention is shown. 
In this embodiment the device 10 includes a plurality of supports 12, one 
for each disc 16 to be stored. 
Each support 12 is slidably mounted on a floor 74 of the device 10. Each 
support 12 slides on a rib 76 projecting from the floor 74. The rib 76 is 
receivable within a complementary groove 78 in the bottom of the support 
12. 
The restraining means includes bias means in the form of a coil spring 80 
to bias the support 12 away from the rear wall 44 of the device 10. The 
coil spring 80 is co-axially mounted on a pin 82 projecting from the rear 
wall 44 of the device 10 into a complementary bore 84 at the rear of the 
support 12. The pin 82 serves as a guide for the coil spring 80 and the 
support 12. The restraining means further includes a shoulder projecting 
downwardly from the top wall 58, near the front of the top wall 58. In 
use, part of the periphery of the disc 16 abuts against the shoulder 86 to 
retain the disc in position on the sloping portion 26 of the support 12. 
In use, to insert a disc 16 into the device 10, it is placed in the slot 36 
extending along the horizontal portion 28 of the support 12 and is then 
rolled up the sloping portion 26 of the support 12 against the action of 
the spring 80. This urges the support 12 towards the rear wall 44 and the 
disc 16 is retained in position by means of the shoulder 86. To remove a 
disc 16 from the device 10, the support 12 is urged in the direction of 
arrow 88 against the action of the spring 80. That portion of the 
periphery of the disc 16 which abuts against the shoulder 86 is then 
disengaged from the shoulder 86 and rolls down the sloping portion 28 of 
the support 12 along the horizontal portion 28, as shown in FIG. 8, under 
the effect of gravity. To facilitate urging the support 12 against the 
spring 80, an upwardly projecting lug 90 is provided at the end of the 
support 12 opposite the bore 84. The support 12 can thus be moved by 
pressing on the lug 90 in the direction of arrow 88. The lug 90 further 
serves as a stop to prevent the disc 16 rolling off the edge of the 
support 12. 
Referring now to FIGS. 9 and 10 still another embodiment of the device is 
shown. 
In this embodiment, the device 10 includes a plurality of supports 12, one 
for each disc 16 to be stored. Each support 12 includes a hinged portion 
90 pivotally mounted at 92 on the floor 74 of the device 10. The bias 
means of the support 12 is a spring 94 (shown more clearly in FIG. 10) 
which acts between the floor 74 and the bottom of the hinged portion 90. 
To permit the hinged portion 90 to lie substantially flush with the floor 
74, the bottom of the hinged portion 90 includes a recess 96 within which 
the spring is receivable when it is in its compressed condition. 
As in the case of the embodiment described with reference to FIGS. 1 to 5, 
the restraining means 18 includes a pivotally mounted lever 20 biased to 
its restraining position by means of a spring 22. The lever 20 includes a 
slot 40 in its shoe 24 within which a part of the periphery of the disc 16 
is receivable. 
The spring 22 is selected so that it has a stronger bias action than the 
bias action of the spring 94 so that the lever 20 will restrain the disc 
in position on the support 12, against the bias action of the spring 94. 
In use, to store a disc 16 in the device 10, the periphery of the disc 16 
is inserted in the groove 36 and is urged into the device 10 against the 
action of the spring 94. As the disc 16 is rolled along the groove 36, its 
periphery abuts against the hinged portion 90, urging it downwardly 
towards the floor 74 against the bias action of the spring 94. Thus when 
the periphery of the disc abuts against the rear wall 44, the hinged 
portion 90 will lie substantially flush with the floor 74. A part of the 
periphery of the disc 16 will then be received within the slot 40 of the 
shoe 24 of the lever 20, which will restrain the disc 16 against rolling 
along the support 12, under the bias action of the spring 94. 
To release a disc 16 from the device 10, the lever 20 is pivoted in the 
direction of arrow 98. This allows the spring 94 to extend causing the 
hinged portion 90 to pivot about the pivot axis of the hinge 92 in the 
direction of arrow 100 (FIG. 10). The hinged portion 90 thereby urges the 
disc 16 out of the device 10 along the support 12.
