Extendible, elastic document fastener

Abstract

The invention relates to a tensile flexibility document fastener for fastening the document with optional thickness. The fastener includes two plates (1, 2) having two perforations or drills (3, 4, 5 6). The first plate includes a vertical slot (7), a banding or rope belt (12) is placed in the vertical slot. The second plate (2) includes four slots (8, 9, 10, 11), two (8, 9) of which extend from the narrow side of the plate (2) to the fixing slots (10, 11). Another two slots (10, 11) are used for fixing the banding or rope belt (12) and extend from the narrow side of the plate (2) to the center, and deflex in the direction of the drills or perforations (5, 6) passing through the banding or rope belt (12) in the center. The depth of slots (7, 8, 9, 10, 11) is equal to the thickness and spaces of the tensile banding or rope belt (12).

Description

technical field [0001] The present invention relates to an extendable elastic document fastener for fastening from a single document to documents of any desired number or thickness in a practical and rapid manner without damaging said documents. The fastener is extremely durable, versatile for all types of documents and suitable for all climates. Background technique [0002] Today, commercially available fasteners are very limited in terms of the number and thickness of documents to be fastened and the storage of said documents. The metal staple fasteners puncture the document and start to rust in wet climates, damaging the document based on customary use. Such fasteners are ineffective for fastening document volumes whose thickness is greater than the fastening length of the fastener. For larger volumes of documents, attach ring, U-shaped or rod fasteners to binders or folders. This has the disadvantage of taking up a lot of space when filing the document, since the met...

Problems solved by technology

Considering this, and the fact that there are no products on the market that are not made of metal to fasten documents for longer storage, there are other disadvantages that cannot be added in a practical way of not having to separate the stitches and sew the paper again or remove loose paper, which wastes time and can damage documents, as the cord sometimes breaks the hole the cord is threaded through

Taking all of the above into account, fasteners of all types make it impossible to see information printed on the document close to the fastener or the pins unless the pins are loose, which reduces the gripping characteristics and makes the document wrap less compact and in turn damage the perforation

On the other hand, if the document is fastened too tightly, the document cannot be handled better, and the information printed on the center near the fastener or pin cannot be read
