ABSTRACT:

This invention relates to a ring binder, and in particular a ring binder with mechanism for releasably holding a compact disk.
BACKGROUND OF THE INVENTION
There are in existence a large variety of ring binders which allow retention and retrieval of loose-leaf sheets. While it is well known to record information and data on paper, with the advancement of technology, much information and data can be and are now stored in and retrieved from compact disks, whether such be audio compact disks, video compact disks or digital video disks. However, existing ring binders do not cater for this technological advancement, and users of such ring binders have to find ways to store the compact disks, which may contain information and data which are relevant to those stored in the loose-leaf sheets retained by the ring binders.
It is thus an object of the present invention to provide a ring binder in which the aforesaid shortcoming is mitigated, or at least to provide a useful alternative to the public.
SUMMARY OF THE INVENTION
According to a first aspect of the present invention, there is provided a ring binder including a ring binder mechanism secured to a base member, wherein said ring binder mechanism includes a pivotable structure to which a plurality of half-ring members are mounted, wherein said pivotable structure is movable between a first configuration in which said half-ring members are open, and a second configuration in which said half-ring members are closed, wherein said ring binder includes at least one holder adapted to be releasably engaged with a compact disk, wherein said holder is fixedly secured to said base member and wherein said holder includes a plurality of securing members penetrable into said base member to fixedly secure said holder to said base member.
According to a second aspect of the present invention, there is provided a ring binder including a ring binder mechanism secured to a base member, wherein said ring binder mechanism includes a pivotable structure to which a plurality of half-ring members are mounted, wherein said pivotable structure is movable between a first configuration in which said half-ring members are open, and a second configuration in which said half-ring members are closed, wherein said ring binder includes at least one holder adapted to be releasably engaged with a compact disk, wherein said holder is movable relative to said base member, wherein said holder is fixedly secured to a board member, and wherein said board member includes at least an aperture allowing a half-ring member to extend therethrough.
