This invention relates to ring binders, and more particularly to ring binders consisting of individual components which are readily assembled and disassembled to permit the use of interchangeable binders and to allow for more efficient and economical packaging and shipment of binders.
Ring binders are usually manufactured and shipped as integral units, with their binder covers and ring assemblies assembled and permanently connected. As a result, once binder covers become worn, the entire binder is discarded. In addition, the packaging and shipment of assembled binders from manufacturer to the wholesaler or retail store is increasingly expensive, given the bulk volume of the many assembled ring binders which are transported in boxed containers.
It is thus the object of the present invention to provide a ring binder which overcomes the disadvantages and limitations of prior ring binder and ring binder assemblies.
It is the object of the present invention to provide a ring binder with the ability to utilize interchangeable binder covers and a single ring assembly.
It is another object of the present invention to provide a ring binder which utilizes a unique binder cover to ring assembly connection, thus permitting different binder covers to be utilized with the same ring assembly.
It is a further object of the present invention to provide a ring binder with components, including a plurality of binder covers, which can be easily, efficiently, and economically packaged and transported for sale and distribution.
These and other objects are accomplished by the present invention, a ring binder comprising a standard ring assembly having a ring base and upstanding rings, a ring assembly support having a plurality of indents positioned along its sides, a binder connector having a plurality of upstanding tabs, and a plurality of binder covers each having a center spine with a plurality of slots configured to accept each of the plurality of binder connector tabs. The ring binder is assembled by the insertion of the binder connector tabs into slots of the binder cover and then into the indents of the ring assembly support. The ring binder can be sold assembled or as a kit, which would include a plurality of interchangeable binder covers.
The novel features which are considered as characteristic of the invention are set forth in particular in the appended claims. The invention, itself, however, both as to its design, construction and use, together with additional, features and advantages thereof, are best understood upon review of the following detailed description with reference to the accompanying drawings.
The components of ring binder 1 of the present invention comprise a standard, spring loaded ring assembly 2 having ring housing 4 and upstanding rings 6. Ring assembly support 8 comprises a plurality of indents 9, 10, 11, 12, 13, 14, 15, and 16, located along the sides of the ring assembly support. Screws and nuts, rivets, or equivalent connecting devices 60 and 62 secure ring assembly support 8 beneath ring housing 4, such that ring housing 4 extends just short of the ends of the ring assembly support, i.e. between indents 9 and 16, and 12 and 13.
Additional components of the invention's ring binder include binder connector 18 and binder cover 28. Binder connector 18 comprises upstanding tabs 19, 20, 21, 22, 23, 24, 25 and 26. Binder cover 28 comprises top cover 40, bottom cover 42, and fold lines 44 and 46 connecting the top and bottom covers to center spine 48. Slots 29, 30, 31, 32, 33, 34, 35, and 36 extend through center spine 48.
Ring binder 1 is easily and securely assembled first by utilizing a flat binder cover 28. Binder connector 18 is positioned adjacent to exterior surface 49 of center spine 48 of cover 28. Tabs 19-26 of the binder connector are then inserted into and through slots 29-36 of the center spine 48. Ring housing 4 with ring assembly support 8 secured thereto is then placed on interior surface 50 of center spine 48, such that tabs 19-26 of binder connector 18 are positioned within and then snapped into indents 9-16 of the ring assembly support. It is contemplated that ring assembly support 8 and binder connector 18 are constructed of a flexible, pliable plastic material. By this construction, tabs 19-26 of binder connector 18 can easily be inserted and snapped securely into indents 9-16 of ring assembly support 8. After binder connector 18 is so connected to ring assembly support 8, both overlaying center spine 48, top cover 40 and bottom cover 42 are folded along fold lines 44 and 46 with center spine 48 therebetween, as seen in
When binder cover 28 needs to be replaced, due to wear or merely at the preference of the user who may desire a different color or alternate decorative binder cover, tabs 19-26 of binder connector 18 are simply and gently pulled out of indents 9-16 of ring assembly support 8. The difference in the degree of plastic material flexibility between binder connector 18 and ring assembly support 8 permits this relatively easy disengagement of the tabs from the indents. A new binder cover with slots 29-36 is then positioned between ring assembly support 8 and binder connector 18 to re-assemble the ring binder.
The components of the ring binder described herein can readily be sold as a replaceable binder kit, with several interchangeable binders. Manufacturing of the ring binder components themselves is economical, in that each component can be fabricated separately, with the binder covers stamped out as flat templates. This also results in efficient, and economical, space saving packaging and storage of the components, for more efficient shipment of the product.
Certain novel features and components of this invention are disclosed in detail in order to make the invention clear in at least one form thereof. However, it is to be clearly understood that the invention as disclosed is not necessarily limited to the exact form and details as disclosed, since it is apparent that various modifications and changes may be made without departing from the spirit of the invention.
