When selecting a binder, consider the materials, as well as what size and ring design is appropriate. Binders come in sizes ranging from half an inch thick to four inches and are commonly made of plastic. Some of these plastics may be plant-based or otherwise eco-friendly, which gives options to the environmentally conscious. Most binders also contain a chipboard inside the vinyl or plastic covers, though some are simply made of thick material.
Another consideration is the customizability of the binder. Many binders come with clear plastic pockets on the front, back and spine. These can be easily labeled or customized by inserting printed paper into the pockets. You may wish to color-code your binders, too.
Ring binders (loose leaf binders, looseleaf binders, or sometimes called files in Britain) are large folders that contain file folders or hole punched papers. These binders come in various sizes and can accommodate an array of paper sizes. These are held in the binder by circular or D-shaped retainers, onto which the contents are threaded. The rings themselves come in a variety of sizes, including 0.5, 1, 1.5, and 2 inches (13, 25, 38, and 51 mm), though other sizes are also available. The rings are usually spring-loaded[citation needed], but can also be secured by lever arch[1] mechanisms or other securing systems. The binders themselves are typically made from plastic with metal rings. Early designs were patented during the early 1890s to the early 1900s.
German Friedrich Soennecken invented ring binders in 1886 in Bonn. He also registered a patent on November 14, 1886, for his Papierlocher für Sammelmappen ("paper hole maker for folders", or hole punch). German Louis Leitz, founder of Leitz, later made some important changes in development of ring binders in Stuttgart-Feuerbach. Leitz introduced the "finger hole" on the side of the binder to aid removal from crowded shelves, thereby creating the modern ring binder.[2]
Another design for ring binders was invented in 1889 by Andreas Tengwall in Helsingborg, Sweden, and patented in 1890 under the name 'Trio binder', named after a business consortium of Tengwall and two associates. Tengwall's design uses four rings, in two paired sets. The hole placement of Tengwall's Trio binder is still used as a de facto standard for hole punching in Sweden under the name triohålning. These holes are 21 millimetres (0.83 in), 70 millimetres (2.8 in), and 21 millimetres (0.83 in) apart.
William P. Pitt obtained patent no. 778070 on December 20, 1904 for a 3-ring binder that became a standard in the United States. The North American de facto standard spacing is 4.25 inches (108 mm) between holes.
Japan uses a unique system, referred to as J-Binder. This system is compatible with A4 and B5 paper with different products. The A4 version uses 30 closely spaced rings, while the B5 one uses 26. Less common variants such as a 20 ring A5 version also exist.[3]
Many personal organizers and memorandum books use a six- or seven-hole system, including Filofax and FranklinCovey. Most systems have the rings on the left side of the papers as one opens the binder, but there are also binders that have the rings (concealed by the binder cover) at the top edge of the paper, reminiscent of a clipboard.
Most binder covers are made of three pieces, in the fashion of a hardback book, with three pieces of board held together with sheets of vinyl or other materials and hinges. Materials vary widely. Some vinyl binders have a clear pocket on the outside for cover pages, and many have pockets in the inner cover for loose papers, business cards, compact discs, etc. There are also zipper binders, which zip the binder up and keep papers from falling out. Some binders are stored in matching slipcases for greater protection; either with one slipcase per each binder, or one slipcase holding several binders.
CH: How did you come up with the creative idea to make your own three-ring binder?EZ: My husband and I operate a small Etsy shop called Droplet, which offers a downloadable and self-printable planner and calendar. One of the planner designs is made to fit within a three-ring binder. Over and over, customers asked where they could find a unique three-ring binder. After researching and then discovering how few unique binder options are available for purchase, I realized that this would be a great project to make. 041b061a72
