1. Field of Invention
This invention pertains to a folder for holding papers and other similar laminar material, and more particularly to a folder having two flat panels interconnected by straps.
2. Description of the Prior Art
Folders are frequently used for both business and personal uses to hold several sheets of documents, pictures, and other thin and sheet-like laminar materials. Existing folders usually consist of two panels joined by a live hinge. Each of the panels is formed with one or more inner pockets. In addition, folders are also available with external pockets. The internal pockets normally extend no more than about half the length of the respective pannel.
A problem with existing folders is that the sheets must be inserted carefully into the pockets so that they are not creased or otherwise distorted. This is problem is especially acute when sheets of several different sizes, shapes and thicknesses are loaded into the pockets at different times. A further problem is that if the pockets are short, they do not provide sufficient support and protection to the sheets, and, as a result, the sheets may fall out.
A folder constructed in accordance with this invention consists of two panels interconnected by two non-overlapping strap systems, each strap system consisting of at least one strap. Preferably at least one of the strap systems consists of two outer straps disclosed close to the top and the bottom of the panels while the second strap system includes one or more central straps disposed between the outer straps. The ends of the straps are connected to the panels.
As shown in
Each strap has two ends, each end being secured to one of the panels, as at 20 by sewing, an adhesive, or other similar securing means. So, for example, one end of strap 16A is secured to one edge of panel 12 and the other end is secured to the edge of panel 14.
As shown in
As shown in
The two lateral edges of panels 12 and 14 are marked respectively as edges 12A, 12B and 14A, 14B. In
An interesting characteristic of the folder 10 is that the two panels can be folded over each along the hinge formed by the strap system between the edges 12B, 14A. Then the two panels can be unfolded by separating the edges 12B and 14A to obtain a new configuration shown in
In this manner a single sheet or a stack of sheets can be stored either by slipping them between the straps and the panels, or by placing them over the one of the panels and then folding the panels twice thereby causing the sheet(s) to be placed into one of the pockets between the strap systems and the panels. In order to support the sheets properly, the distance between the straps of each system must be smaller than the length of the sheets.
While the invention has been described with reference to several particular embodiments, it is to be understood that these embodiments are merely illustrative of the principles of the invention.
