DESCRIPTION:
BRIEF SUMMARY
The invention relates to ring binders and the like.
Ring binders are commonly used in offices and elsewhere for use in pamphlets, booklets, bundles of papers and so on. A bundle of pages is held together at its one side by plastic rings which form a hinge so that the pages can be turned one at a time about the hinge.
Ring binders which are generally available are normally inserted using a manually operated press into which the one sides of the pages are inserted and aligned together as a bundle. The press grips the pages and when operated punches holes along and adjacent the one side for accommodating the plastic rings. The press is then opened and the plastic rings, normally held together by an integrally formed linking member, are inserted into the punched out holes.
So called "ring binders" may also use a spiral wire hinge or a simple clamping arrangement which holds the one sides of the pages together. Such a clamping arrangement can consist of a strip of plastic at each side of the bundle which extend adjacent and along the one side of the pages. The strips are held together by rivets or other connectors which pass through apertures in the pages normally formed by the press.
In this specification we therefore use the term "ring binder" to mean all forms for binding of bundles of sheets of material (usually paper or plastic) to keep them together along one side. The sheets are held by plastic or metal pieces which pass through holes in the one sides of the sheets and allow the sheets to be turned in a manner similar to the pages of a book.
At present ring binders suffer from the disadvantages that the outer appearance cannot be particularly aesthetic, that the rings (or similar) can easily catch against and engage each other, from one ring binder to another, and that other objects and articles in a general office environment, for example, can become easily entwined with the exposed ring binder.
It is an object of the invention to overcome or at least reduce this problem by providing a convenient folder or outer cover for a ring binder.
According to the invention there is provided a folder comprising an upper cover and a lower cover for a ring binder arranged to surround the ring binder and to lie over an upper and lower face of a bundle of sheets of material held by the ring binder, in which the lower cover has a lip at one side which extends towards the ring binder and away from which the lower cover is arranged to fold to allow the lip to enter a binding press and be punched through in use with the rest of the sheets.
The folder may extend to cover the whole of the upper and lower surface and the lip provided on a sheet of material fixed over an inside of the lower cover except for a small region to form the lip. Alternatively, the lip may be formed by one side of a strip of material fixed along adjacent its other side to the inside of the lower cover.
A narrow strip of material may be attached centrally where the upper and lower cover meet to the inside of the folder to extend in use along the outside of the ring binder. The strip of material may have an exposed sticky surface which sticks to the ring binder to hold the folder against the ring binder.
A folder for a ring binder will now be described by way of example with reference to the accompanying diagrammatic drawings in which:
FIG. 1 is an inside plan view of the folder;
FIG. 2 is a side view of the folder;
FIG. 3 is a side view the folder enclosing a bundle of pages; and
FIG. 4 is an enlarged isometric partial view of a ring binder.
Referring to the drawing, the folder has a lower cover 10 (which normally forms the back of a bound bundle of pages) and an upper cover 11. The lower cover 10 has a sheet of cardboard 12 stuck to its inner surface except along one end where, as shown in FIG. 2, it forms a lip 13 which extends beyond a fold line 14 of the lower cover. A narrow strip of double sided sticky tape 15 is attached to the inside of the folder to lie in use opposite a ring binder 16 (which has conventional configuration best shown in FIG.
