Background of the invention

The lecterns and facistoles are known and used since ancient times in many different forms and materials, being used to view or read documents and books, sheet music such as exhibitors of paintings, photographs, advertising, etc. The up now existing are usually objects of a certain volume, uncomfortable and somewhat heavy and being impractical have fallen into disuse although ergonomics experts strongly recommend their utilization.

There are other devices on the market with articulated arms to be fixed to the tables or to the computer screens with limitations and difficulties for your utilization.

In different fields, the folder market It has specific solutions according to utility being manufactured with great variety of shapes, models and materials. However in the Market research conducted we have no record of the existence of some similar solution to also use as lectern with the exposed characteristics.

Description of the invention

With the same layout of a folder for documents or books the lectern folder consists of two covers, plates or boards of very little thickness but more stiffness than this case they are articulated with simple piano hinges or also composed in "W" of three folding pivots that join Its common edges. In one of these caps there is trimmed in its inner part one or two complementary pieces in the form of trapezoid or parallelogram that are joined by one of its edges parallel to the opening axis of the folder and pivots towards the inside the lid itself of which it is part. Parallel edge opposite of this piece or pieces, when it opens it stops in the face inside the opposite cover of the folder where it has a Velcro strip removable type that serves to fix and adjust the inclination to arm as a lectern.

In the lower part of the outer face of this lid and parallel to the hinge that articulates the folder is fixed and fully folded on itself an elongated joint of three sheets with limited opening that opens in a box discovered and serves as the lower stand of the music stand to place the lower edge of documents, books, etc.

If it is two pieces the device that forms the pole, allows to open and lift the board up to the vertical front stand stand. In this case with the devices of Figure 8 can be fixed side stops and boards or frames folding townhouses. In any case the device serves to adapt the vision and the frontal reading reporting to the user advantages Ergonomic to avoid awkward body postures and lights or annoying reflections in sight.

As the manufacture and use of music stands or folders are still made in two different solutions, the lectern folder with this ambivalence solves the two different uses respecting the shape of a folder and that of a music stand perfectly valid.

Other problems and objectives resolved have been lighten it to its minimum weight and volume, change the system used so far to create music stands and design accessories Fully folding precise to carry in your hand as a folder with books or documents and also a lectern that can keep folded in a minimum space for both uses.

The boards or irons used have shapes and sizes equal or similar to a folder and have an edge common that articulates its two faces to also serve as a lectern and folder but can be built with measures and multiple shapes and varied.
