ABSTRACT:

FIELD OF INVENTION
The present invention is an improvement in or relating to a media storage disk case.
BACKGROUND TO THE INVENTION
Media storage disks such as compact disks (CD), digital video disks (DVD) or video compact disks (VCD) have rapidly gained popularity with consumers. For the purposes of retail, transportation, and storage by the end user, such disks are normally provided contained within a case. Different types of CD, VCD or DVD cases are known. Such normally include a disk engaging means which is arranged such that when it is pressed, the perimeter profile of the engaging means changes and reduces the degree of hold that it provides to the disk.
The construction of such disk engaging means is complex.
It is therefore an object of the present invention to provide improvements in or relating to a media storage disk case which will at least provide the public with a useful choice.
BRIEF DESCRIPTION OF THE INVENTION
Accordingly in a first aspect the present invention consists in a media storage disk case, for a media storage disk of a kind including a central aperture, said case comprising;
a body portion having a substantially planar base, for receiving a media storage disk, wherein the plane of said disk is substantially parallel to the base,
a first disk engaging member to engage onto part of the outwardly facing surface of said disk at no more than half of the perimeter of said central aperture,
said first disk engaging member cantilevered from said body portion on a resiliently flexible arm extending at an angle away from said body portion,
a second disk engaging member to provide support at part of the downwardly facing surface and to at least the same said half of said disk,
a third disk engaging member provided to engage with said disk to prevent movement of said disk in at least a direction of said half of said disk,
wherein said first engaging member is able to move from a first condition for engagement with said disk, to a second condition towards said body and disengaged from said disk, whilst said second disk engaging means provides the upward support to said disk.
Preferably said first disk engaging member engages onto part of the outwardly facing surface of said disk at said central aperture, at less than half the perimeter of said central aperture.
Preferably said disk engaging member engages onto the outwardly facing surface at the edge of the central aperture of said disk at less than a 60° quadrant.
Preferably said angle of said arm is defined in a plane normal to the substantially planar base.
Preferably said angle has a longitudinal component and a vertical component to position said first disk engaging member at a height above said substantially planar base.
Preferably the end of said arm forms or has engaged thereto a push button member engagable by the digit of as user of the case to allow the selective pressing of said button to thereby move said first disk engaging member to or towards said second condition.
Preferably said second disk engaging member is at least one upstand from said body portion to be in contact, at least when an undesired removal force is applied to said disk, with part of the downward surface of said disk.
Preferably said second disk engaging member is an upstand of said body to be in contact with the downward surface at the perimeter region of said disk.
Preferably said upstand is a rim provided to underlie the entire perimeter region of said disk, save for at least one relief, or gap.
Preferably the height of said relief or gap is substantially equal to the height of said upstand.
Preferably there are four reliefs provided in the upstand.
Preferably each relief is of a width to allow at least a portion of a digit of a user to insert therethrough, to provide an uplifting force to the outward perimeter edge of said disk.
Preferably said third disk engaging member prevents movement of said disk in substantially all directions parallel to the plane of said disk.
Preferably said third disk engaging member is a ridge providing a substantially vertically (normal to the plane of the disk) extending surface.
Preferably said vertically extending surface is provided by said upstand of said body.
Preferably movement of said disk in at least a direction of said half of said disk is also restrained by a member provided to engage against the edge of said central aperture substantially at least diametrically across from where said first disk engaging member engages onto the disk.
Preferably such is provided by the opposite edge of said push button member.
Alternatively such is provided by a lip extending from the planar base of said body portion.
Preferably said lip extends from said planar base to have some degree of flexible rigidity.
Preferably said push button provides a region to contact the edge of said central aperture substantially immediately adjacent said first disk engaging member to prevent said disk from moving in a direction substantially parallel to the plane of the disk, in a direction away from said half.
Preferably there is only one first disk engaging means, located on one cantilevered arm.
Preferably said body portion has a cover portion hingedly engaged thereto.
This invention may also be said broadly to consist in the parts, elements and features referred to or indicated in the specification of the application, individually or collectively, and any or all combinations of any two or more of said parts, elements or features, and where specific integers are mentioned herein which have known equivalents in the art to which this invention relates, such known equivalents are deemed to be incorporated herein as if individually set forth.
The invention consists in the foregoing and also envisages constructions of which the following gives examples.
