Abstract

The object of the invention is a method for stacking books on a book shelf, and a shelf for stacking books, designed to be fixed on a vertical wall.

A method for stacking books on a book shelf, wherein the books are suspended from the bottom of the shelf in such a way that the upper sides of the books are under the lower surface of the bottom panel of the shelf, consists in the fact that each book is fixed by inserting a thin tendon between the pages of the book, which is terminated at the bottom by a stop on which the book seated on the tendon rests with its lower side. The length of the tendon is selected so that the distance between the stop and the lower surface of the lower shelf plate is equal to the height of the book to be fixed and the book with its upper side is in contact with the lower surface of the lower shelf plate.

The book stacking shelf according to the invention has at the bottom along the entire length of the lower shelf plate 3 of the shelf 1 a number of tendons 7 of fixed or adjustable length, each tendon 7 at the bottom having an attached stop 8 determining its length. Preferably, each tendon 7 most often has an adjustable length, in which case each upper end of each tendon 7 is wound onto a shaft 4 of a winch, individual for each tendon 7. The winches are attached to the lower plate 3 or upper plate 2 of the shelf 1, advantageously in the interior of the shelf 1 between its upper plate 2 and lower plate 3. The mechanism for tensioning the tendon 7 in each winch is its respective tension spring 9. The winches are fixed in a row in the interior of the shelf 1 and under each of them in the lower plate 3 of the shelf 1 there are holes 6 through which the tendons 7 are threaded with stops 8 at the lower end.

Description

The object of the invention is a method for stacking books on a book shelf and a shelf for stacking books, designed to be fixed on a vertical wall.
Book shelves are known, the essential part of which is a plate, perpendicular to the wall, usually horizontal, on which, on its upper surface, books, albums, brochures and similar items are placed vertically. The shelves have vertical walls at their sides against which books are supported to keep them upright, and shelves without such walls are fitted with lateral supports that slide along the horizontal panel. The shelf is in the shape of a long rectangle and one of its longer edges is fixed to the wall. From the description of the Chinese utility model No. CN207744878U , a shelf is known, named there as an over-and-under shelving unit, where there are several shelves one above the other, all of them horizontal, all of them fastened at the sides by vertical walls. The shelves have adjustable spacing to accommodate books of different sizes. Books are positioned on the top surfaces of each shelf. Shelves are known to have a smaller shelf underneath, for office supplies and similar small items - here again, these items are placed on the top surface of the lower shelf and books are placed on the top surface of the upper shelf. There are known invisible book shelves, shown no. at https://www.youtube.com/watch?v=NT3VZRcfyMo - here the main part is a sturdy horizontal support - a horizontal plate - attached to the wall. One of the books, not intended for reading, redundant in the book collection but e.g. decorative, is used as a horizontal base for others which are stacked on it. In the base book, a pocket is made by gluing a few sheets of paper to the sides of the cover and, using the pocket created in this way, the base is slid onto a horizontal support which disappears inside the base book and is therefore invisible to the observer. On this horizontal base, books are usually placed horizontally, but they can also be placed vertically, depending on the owner's preference. Other hanging book shelves are known, developed by various designers for decorative and practical purposes, in which, for example, the plate for placing books on it is not horizontal, but has the form of a wave, an oval or is diagonal. In all of them, even the most fanciful designs, books are always placed on the top surfaces of the plates and supported at the sides. The website https://www.youtube.com/watch?v=u6y_5uFdAvk&ab_channel=Homedit%C2%AE shows a method of stacking books from the bottom of the shelf, where books are suspended from the bottom of the shelf so that they hang below the shelf rather than standing on it. To achieve this, loops are made from rubber - bands - with which the books are strapped, the bands being fixed to the underside of the shelf. Once the rubber band is tightened, each book is slipped into its designated loop and the book hangs in the loop under the bottom surface of the lower shelf plate. However, the end result is spoilt by the fact that the books hang in disarray, as the distances of the upper sides from the lower shelf plate vary according to the weight of the book.
According to the invention, a method of arranging books on a book shelf, where the books are suspended from the bottom of the shelf in such a way that the upper sides of the books are under the lower surface of the lower shelf plate, consists in the fact that each book is fixed by inserting a thin string between the pages of the book, which is terminated at the bottom by a stop on which the book, which is seated on the string, rests with its lower side. The length of the string is chosen so that the distance between the stop and the lower surface of the lower shelf plate is equal to the height of the book to be fixed, and the book, with its upper side, is in contact with the lower surface of the lower shelf plate.
The book stacking shelf according to the invention has at the bottom along the entire length of the lower shelf plate a number of tendons of fixed or adjustable length, and each tendon at the bottom has a stop attached to it which determines its length.
The stop is most often a narrow flat bar, in the middle of which is the point of attachment of the tendon.
In another version, the stop is a decorative figure.
It is advantageous if each tendon has an adjustable length. Each upper end of each tendon is wound onto a winch shaft, individual for each tendon. The winches are attached to the bottom plate or top plate of the shelf, advantageously in the interior of the shelf between its top plate and bottom plate. The tendon tensioning mechanism of each winch is its respective tension spring.
The winches are fixed in a row in the interior of the shelf and under each winch there are holes in the lower plate of the shelf through which the tendons with stops at the lower end are threaded.
Ideally, the holes are slots parallel to the axis of the shafts.
A torsion spring is used as the tension spring, which is located inside the winch shaft.
The method of placing books on the shelf and the bookshelf fixed to the shelf by the method according to the invention allows for an original visual effect that seems to contradict the laws of physics, which will be described in more detail in the following section.
The shelf according to the invention is shown in an example of execution in the drawing, in which fig. 1 shows a shelf fixed to the wall and books attached to it, fig. 2 shows an illustrative drawing of a shelf with adjustable length tendons, where the tendons are wound on winch shafts, and fig. 3 shows a single winch tension mechanism for positioning books.
As shown in fig. 1, the book shelf is a thick, rectangular plate 1, with an upper plate 2 on which various objects are placed, here flowers, ornaments, it can also be books, and with a lower plate 3 to which the books are fixed. As can be seen, the books are fixed by the method according to the invention from underneath, they hang below the lower plate 3 remaining in contact with it by their upper sides. The positioning of the books is very aesthetically pleasing, all of them being in contact with the shelf. As shown in fig. 2, the plate 1 is hollow in the middle, between the upper plate 2 and the lower plate 3 there is a mechanism to fix the books to the underside of the lower plate 3. In detail, this mechanism is shown in fig. 3 and is a winch, the shaft 4 of which is placed in a frame 5 and this frame 5 is fixed to the lower plate 3 in the interior of the plate 1. On the shaft 4 is wound a tendon 7, which is terminated at the bottom by a stop 8, which determines the length of the tendon 7. In this example of execution, the stop 8 is a narrow flat bar, fixed in the middle to the tendon 7. The tendons 7 are threaded through holes 6 in the lower plate 3, in this example these are transverse slots, parallel to the axis of the shaft 4. A tension spring 9 is placed inside the shaft 4. This mechanism enables the length of the tendons 7 to be adjusted - depending on the vertical dimension of the book to be hung, the tendons 7 are unwound from the drums 4 and pulled downwards through the holes 6 in the lower plate 3. Then the ties 7 are inserted between the pages of the books, the stops 8 rest on the lower sides of the books and by the force of the tension springs 9 the books are pressed against the lower board 3 from below with their upper side. The stops 8 fit between the covers of the books, so they remain invisible to the observer and the books look as if they are glued to the lower board 3. As you can see, the books do not stand on the shelf, but are attached to it from below, with invisible fasteners, which gives an amazing visual effect. This effect can be enhanced by using a decorative figure, such as Atlas bearing the celestial vault, as a stop. For each book there is its own fixing mechanism - the hoists are placed side by side inside shelf 1.
