Abstract

The system has elastic structures (2) placed in front and back portions of a book. Two separate tread-pages (1) are inserted on the elastic structures, and tabs are arranged at different distance and different height from each other and made of transparent material. Tread-trap page edges of the book are placed between the elastic structures. Two independent parts are attached with the elastic structures and the tread-pages. An elongated element (3) is inserted between two intermediate pages of the book.

Description

Support and clamping system for reading books, with page holders, adjustable to different Book sizes and different reading positions.

The present invention relates to a system of support and support for reading books, with page holders, adjustable to different sizes of book and different reading positions, even in the position of reader lying on its back, allowing the page to turn comfortable.

Technical sector

Devices for holding books or documents, music stands, reading accessories, technical aids for disabled.

State of the art - Background of the invention

The present invention relates to a system of book retention that brings substantial news in the performance and modes of use of conventional music stands. The system will serve as the basis for the construction of lectern models  specific but also with some specific modalities of system implementation, can be added to some lecterns Conventionals already existing to provide them with the functionalities that contribute.

The new system allows the clamping of any type of book or magazine through a system of adjustment to different formats At the same time it makes it possible to pass sheets without having to modify The position of the book. The clamping system will work in different positions, being able to be placed in an inverted position, so that the reading can be done by the individual in horizontal position or similar.

There are many types of lecterns, being able to classify them into four large groups:

to)

First those lecterns that do not incorporate any fastening system of pages, constituting only a way of supporting documents, incorporating some of them, a system of regulation of tilt and fold. These lecterns have important limitations, when they are intended to be used for reading books, such as not holding pages, not being able to keep certain open book formats, or that of not being Adjustable to different formats. In addition its regulation system it only reaches the reading in a vertical pseudo plane.

b)

Then we find those lecterns that incorporate different systems of fastening of pages (tweezers, tabs ...). These lecterns normally  they have the disadvantage of having to move the system clamping every time you want to turn the page, also usually conform only to standard formats. Nor do they incorporate the possibility of reading in an inverted position, since the system of clamping is not designed for that purpose.

c)

Also exist music stands based on the use of transparent material boards that allow you to read the book through the lectern itself but that they also have difficulties when turning the pages to present a barrier between the book and the reader.

d)

By last we find those lecterns that incorporate mechanized systems, intended to facilitate the change of page without using a medium Handbook. These lecterns, usually very expensive, incorporate mechanisms large, which hinder their domestic use, in addition neither do they allow reading in an inverted position, or the use in different positions (table stand and music stand foot).

The system presented constitutes an advance Qualitative in the functions of the traditional music stand. Provide one versatility and diversity of position options, which until now they were difficult to obtain (reading in inverted position, change of page without moving the clamping system, use as a music stand foot or desktop ...). In addition the clamping system can be adapted to different book sizes and has the advantage of being able to be used both for home use (read on a sofa, on a table, in a bed ...), as well as for more functional use for people with accessibility problems (people with disabilities, people with restricted mobility, hospitals ...).

Explanation of the invention.

Figure 1 shows the system of holding the book open by the desired page that is based on the action of the footprints (indicated in the drawing with the number 1 notice that there are two pisa-pages) when catching the edges of the readable faces of the open book between them themselves and elastic structures (indicated with the number 2). The book is also reinforced with the use of the filiform element (3) that inserted between two of the pages in the middle of the book, it will imprison the back of the book against the structure that serves as a lectern. When the book fits perfectly trapped, the system will work even in an inverted position, it is say, assuming the music stand suspended over the reader's head, with the book open with readable faces looking down (figure 2).

The elastic structures (2) may be implemented using different materials and shapes (springs, sponges, silicones, ...) being able to be fixed or mobile on the structure used as the base of the music stand. In case of being mobile, its movement system will be in solidarity with that of the pisa-pages, so that the latter always can catch the edges of the readable faces of the open book against elastic structures. The system can work also using a single elastic structure that covers all the Useful surface of the music stand, acting in this case each of the step on pages on a different area of this elastic structure (figure 3).

The pisa-pages have a size such that they can put pressure on the side edge of the faces readable from the pages of the open book and preferably will be transparent so that they disturb as little as possible if they reach Overlap on written text.

Once the open book is placed in the system clamping, slight pressure on the open page that we want to pass will yield the corresponding elastic structure allowing release the grip to turn the page of comfortable way. Also, once. turned the page through another slight pressure on the other part of the book we will get slide the last page between the footer and the  elastic structure on that side (figures 4 and 5).

Each of the pisa-pages can approach or move away from its corresponding structure elastic, but in turn, its displacement system allows set it at will at a certain distance the structure elastic so that it imprisons the edge of the readable page (and the pages behind it) between himself and the aforementioned structure. This movement allows the system to hold open books of different thicknesses, as well as the same book both when it is opened by one of the first pages and by one of the latter, being able to adapt the force exerted by the pisa-pages about the book and structures elastic The direction of this movement is indicated in figure 6 for each of the pisa-pages. The reader can need to readjust the position of the footprints after reading a considerable number of pages since there will be significantly varied page set thicknesses read and pending to read.

Each of the pisa-pages can in turn move along an axis perpendicular to the formed by the spine of the book and parallel to the plane formed by the structure that serves as a lectern. This displacement system it also allows you to set the footprints to a determined distance from the mentioned axis so that each of they can the one on the readable page and the ones behind she between himself and the elastic structure but superimposing the smallest possible area of footprints on the written text so as not to disturb the reading. This movement allows that the system adapts to different sizes of pages, covers and back covers. The direction of this is indicated in figure 7 movement for each of the pisa-pages.

To complement the subject of the book, the The system incorporates an auxiliary filiform element (3).

The filiform element (cord, wire or similar, elastic or not), inserted between two of the pages intermediate of the book and fixed by its ends to two points of the base of the lectern runs parallel to the axis formed by the junction of the pages of the open book, and imprison the spine of the open book against the base of the lectern improving the grip on all in case the book is on the head of the reader.

This item may be released by one or two of its ends (in figure 1, one of the ends is shown loose) easily allowing adjustment on the spine of the book open to fix this to the fastening system and release of the  tension to get the book out of it.

The thin thickness of this element allows a once inserted between the intermediate pages of the open book, no suppose an obstacle to turn the pages on it, without need to release any of its ends. We can see it graphically in figures 4 and 5.

Below is another alternative of system implementation that respects the essentiality of it and which allows to incorporate the functionality of the system to the lecterns already existing.

This alternative embodiment is based on make elastic structures independent and pisa-pages of the structure that serves as the basis of the lectern, implementing the clamping system with two pieces which can be added to a conventional music stand.

This way you get that, adding these independent parts on both sides of a conventional music stand, we can provide it with the functionality of holding the open book through the desired reading page allowing the comfortable passage of page offered by the system object of the invention. In the figure 8 shows an embodiment of one of these pieces.

To achieve system adaptability to different book sizes with this alternative embodiment, these pieces must be able to move along the lectern conventional and its displacement system will allow them to remain fixed in the desired position coinciding with the edges of the pages of the open book.

Also, in the same way as in the option explained above, the pieces will incorporate some system of vertical scrolling of the pisa-pages (by example a telescopic system, a figure 8 is shown telescopic system with screw fixing) with the possibility of fixing in a certain position, so that these pieces can hold open books of different thicknesses, as well as a same book both when open by one of the first pages as one of the last, to adapt the force exerted by the pisa-pages on the book and the elastic structure

Explanation of an embodiment of the invention

The following is an example of a way of embodiment of the invention, a lectern model incorporating the system object of the patent. It is a music stand that can be used as a music stand suspended from an articulated arm or as a music stand desktop, as it incorporates a system of coupling and disengagement simple based on the thread systems used in the photography tripods and capable of working with different Accessories (articulated arms, mini-tripod, mono-foot ...).

Figure 9 shows the music stand indicating with numbers the fundamental elements of the system object of the patent (with 1 pisa-pages, with  the 2 the elastic structures and with the 3 the filiform element). In the later figures the different pieces that are detailed it's made of.

In this case the structure that serves as the basis of the lectern is a wooden board on which the book will rest open. To this table has been added another smaller embedded perpendicular to the first one at the bottom of it to facilitate book support when the music stand is in inclined plane position, as most lecterns incorporate conventional. Figure 10 shows the base structure of the  music stand with the filiform element fixed at the lower end.

On both sides of the base table of the music stand they have practiced two slits that will serve as a lane so that they can move the pieces (also of wood, with H-shaped section lying down) incorporating the structures elastic and the pisa-pages. Friction itself of the wood makes the pieces stable in the place where let's leave them. The movement on these rails allows to adapt the book fastening system with different page widths and covers.

These pieces are detailed in Figure 11. The elastic structure (2) has been implemented by embedding a spring between the moving part and a smaller splint on which support the cover or back cover of the book (depending on the left or right side).

The pisa-pages (1) are formed by transparent methacrylate slats with the thickness enough to put pressure on the pages of the book open. To provide mobility footprints in the sense of being able to zoom in or out of structures elastic to put pressure on the pages of the open book, in one end of each methacrylate tablet has joined a rod of small thickness and circular section, perpendicular to the methacrylate tablet. These rods are housed in two holes like tunnels in moving parts being able to cross them. The moving parts in turn incorporate a button that when activated allows the rod in question run through the mentioned hole. In this way if the user does not exerts pressure on the push button, the rod is fixed and therefore the page stitches will also be fixed to one certain distance from its elastic structure.

The push button system is easily achievable practicing a cylindrical hole in the moving part, to accommodate in this one a small pier (invisible in the figures by be inside the piece) and a cylindrical rod of wood that will act as a push button. The spring is positioned which tends to eject the stem. This wooden stem is drilled perpendicularly through a hole (also invisible in the figures) thicker than the diameter of the rod attached to the step on pages, so that the rod can run through this hole, except when the spring exerts pressure on the rod preventing the rod from sliding by jaw effect.

To complete the system functionality of clamp incorporates a cord (3) that is fixed by one of its ends to the bottom center of the board serving of the lectern. The other end can be set to release at convenience to be able to fix or release a book from the lectern using it a circular piece is located at the top rear of the base table of the lectern. Figure 12 shows the back of the music stand with the fixing system of the filiform element.

Also on the back of the base table of the lectern, a nut has been embedded, visible in figure 12, with universal photography thread that will serve as a system for hook to articulated arms (for example those used in photograph to hold and orient spotlights at different angles) or to mini-tripod or mono-foot systems. In the first case, use of articulated arm which in turn it can be hooked to a table or a tubular structure like those of hospital beds, we can use the music stand in position of lying down while the second case, mini-tripod or mono-pie, it would be more Suitable for using the music stand as a desktop item.
