Description

DEVICE FOR HOLDING PAGES OF BOOKS IN OPEN

PROVISIONS

Technical field

The invention relates to devices for use with books and similar stitched printed materials, in particular to a device for holding pages of books and other stitched printed materials in an open position.

State of the art

Known bookmark for books, including an element that fixes a book page [utility model RU 26772, publ. December 20, 2002]. The fixing element is made in the form of a closed elastic-elastic tape, which when installed on a thin book covers several required pages along with the cover of the book. The tape is made of rubber or polymer latex, and on its visible surface an image is applied in the form of a geometric figure or other figurative element, on which a pointed pointer is placed to mark a line of text on the page. Despite its simplicity, the known bookmark has a limited scope, since the fixing element does not have the ability to resize sufficiently to fix a different number of pages in books of various thicknesses and formats, while such a fixing element or weakly holds a small number of pages or pages of a small format book, or it is very tight when holding a large number of pages or pages of a large format book, which can cause pages to wrinkle, especially their edges aev, or cause the locking element to break.

A device for holding pages in an open position while reading a book is known, which comprises a sliding case made up of two L-shaped staples movable relative to each other, each of which includes a support bar and a gripping plate L-shaped [application JP 2000343860, publ. 12.12.2000]. L-shaped staples are equipped with means for fixing their relative position in the form of a screw clamp. The device is capable of reliably holding several pages only at a certain thickness of such captured pages, which limits its scope for books of various formats or for various thicknesses of captured pages. As a prototype of the selected device for holding the pages of the book in the open position [patent US 4285532, publ. 08/25/1981]. The device includes a housing, at the opposite ends of which two retractable support strips are installed, having lateral hook-like bends at the ends, intended for engagement with the upper or lower edges of the book cover. On one of the hook-shaped bends a pivot arm is installed, which is spring-loaded and provided with a gripping rod at the free end. In the working position of the device, the support bar and the pivot arm form an L-shaped bracket in a side view. The known device has a relatively complex structure. Also, if it is necessary to hold a sufficiently large number of pages, the pivot arm is rotated relative to the edge of the hook-shaped bend almost at an angle of 90 °, i.e. almost dead center, which does not allow you to reliably hold the page due to the spring force.

Disclosure of invention

The technical task to be solved is to simplify the design of the device for holding book pages in the open position and to ensure the reliability of page retention for books, regardless of the number of pages held simultaneously.

To solve the technical problem, a device is proposed for holding book pages in an open position, containing two L-shaped staples, each of which includes a support bar having a transverse hook-shaped bend at its first end, which is designed to engage the upper or lower edges of the cover books, and a lever mounted cantilever at the end of the hook-shaped bend perpendicular to the support bar, designed to hold several pages between the cover of the book and the top page of the book in its in a closed position by means of a page gripping tool provided on the lever, as well as a connecting means connecting the second ends of the support strips of the L-shaped brackets so that both support strips rest on the front side of the book cover and are held on the book cover when the second ends of the support the strips are directed towards each other when the hook-shaped bends are hooked to the upper and lower edges of the book cover, respectively, in the working position of the L-shaped staples, while the connecting means is arranged to adjust the distance between the support bars. What is new is that the lever is made in the form of a gripping bar fixed at one end with one end thereof the hook-like bending of the support bar, while the material of at least the hook-like bending is elastic, allowing elastic angular displacement of the gripping bar relative to the supporting bar when external force is applied to the lever and the gripping bar is returned to its original position perpendicular to the supporting bar when external force is removed moreover, the means of capturing pages is made of at least one row of teeth made on the gripping bar along it so that the teeth are facing the edges of the pages of the book in working position L-shaped staples. Thus, a series of teeth, spring-loaded elastic hook-like element in the working position of the L-shaped staples, reliably holds the edges of many pages to be held.

The support bar and the gripping bar of the L-shaped bracket can be made in one piece, while the end of the hook-shaped bend smoothly passes into the gripping bar.

Two or more rows of teeth may be performed on the gripper bar.

The width of the gripping bar may be less than the width of the support bar.

In this case, it is better when the gripping bar is fixed at one end at the end of the hook-shaped bend of the support bar in the middle of it, which reduces the likelihood of the skewed L-shaped staples in their working position.

The connection means may include grooves made on one support bar, which includes another support bar with the possibility of longitudinal displacement of the support strips relative to each other, and fixing means made on the support strips, allowing to fix the position of the support strips relative to each other. In this case, the grooves can be longitudinal and run along the lateral edges of one of the support strips, bent towards each other. Additionally, the fixing means may include a series of troughs or holes made on one support bar with a certain step along it, and at least one protrusion made on another support bar with the ability to enter into the said troughs or holes for fixing the position of the support bars relative to each other .

Also, the connection means can be made in the form of an elastic elastic elongated element, the ends of which are connected to the second ends of the support strips of the L-shaped staples, respectively. Here, the elastic elongated member may be provided with tension adjusting means in the operating position of the L-shaped staples. The elongated elastic element can be made in the form of an elastic tape, with transverse grooves being made at the second ends of the support strips to secure the corresponding ends of the elastic tape in them, and the width of the transverse grooves corresponds to the width of the elastic tape. Here, because the plane of the elastic tape and the plane of the support bars are parallel to the plane of the book cover, the device is more securely attached to the book cover.

The gripping bar can be equipped with a retractable element with a series of teeth made on it, made to extend along the gripping bar, which increases versatility when used due to the possibility of adjusting the total length of the gripping bar.

The teeth can be made on one of the sides of the gripping bar. Other warrants of their location are possible, for example, along the middle longitudinal axis of the gripping bar.

Preferably, when the tops of the teeth are rounded.

It is also preferable when the height of the teeth is made greater than their thickness. In this case, the teeth can be tilted towards the support bar.

The device may include an elastic cord, the ends of which are made with the possibility of fastening on hook-like bends of the support strips or near them on the support strips.

Hereinafter, the terms “longitudinal” and “along” mean the direction of the longitudinal axis passing from one L-shaped bracket to another L-shaped bracket through their central sections or in the working position of L-shaped staples. Accordingly, the terms “transverse” and “transverse” mean the direction of the transverse axis, which is perpendicular to the above longitudinal axis and lies in the plane of the support strips.

The best embodiment of the invention

The invention is illustrated by two specific examples of carrying out the invention.

Example 1. A device for holding pages of books in the open position with sliding means for connecting L-shaped staples (Fig.1-3).

The device of example 1 shown in FIG. 1-3 includes an upper L-shaped bracket 1 and a lower L-shaped bracket 2, all elements of each of which are made in one piece with the corresponding L-shaped bracket of a suitable elastic material, for example, sheet metal or polymeric material. L-shaped staples contain: elongated support strips 11 and 21, transverse hook-shaped bends 12 and 22, gripping planks 13 and 23, rows of teeth 14 and 24, respectively.

There is a means of connecting the support strips 11 and 21, including longitudinal grooves 15 made on the lateral edges of the support bar 11, which includes the support bar 21 with the possibility of longitudinal displacement relative to the support bar 11. The connection tool also includes means for fixing the relative position of the support bars 11 and 21 comprising a series of holes 25 made in the support strip 21 with equal pitch along the longitudinal axis 3, as well as a protrusion 16 made on the support strip 11 and having dimensions and shape allowing it to enter the holes 25 of the supports no bar 21.

When using the device, the upper L-shaped bracket 1 and the lower L-shaped bracket 2 are installed on the cover of the book using hook-shaped bends 12 and 22, hooking them to the upper and lower edges of the cover of the book, respectively, so that the L-shaped brackets 1 and 2 were in the working position, when both support strips rest on the front side of the book cover and are placed on one longitudinal axis 3, located perpendicular to the upper and lower edges of the book cover. The distance between the support strips 12 and 22, and accordingly in fact, the distance between the hook-shaped bends 12 and 22 and the corresponding gripping bars 13 and 23 is adjusted by aligning the protrusion 16 with one of the suitable holes 25 due to the corresponding longitudinal displacement of the support bar 21 in the longitudinal grooves 15. Also, in this case, the teeth 14 and 24 hook over the edges of the page of the book, holding them securely due to the elastic force of the hook-shaped bends 12 and 22, because first, when installing the L-shaped brackets, the gripping plates 13 and 23 are displaced in the angular direction with respect to the supporting bars 11 and 21, diverging from each other, and then, under the action of the indicated elastic force, the gripping bars 13 and 23 tend to return to their the initial position perpendicular to the respective support strips 11 and 21, due to which the teeth 14 and 24 penetrate between the held pages of the book, capturing them. To remove the device from the book, it is enough just to slightly extend the gripping bars 13 and 23 in the angular direction, and then remove the L-shaped brackets 1 and 2 from the cover of the book.

Figure 4 shows one of the modifications of the device according to example 1, mounted on a book. In this modification, there is an additional element in the form of a rubber cord 4, the ends of which are detachably connected with hook-shaped bends 12 and 22. This cord 4 can be used, for example, as an additional bookmark or to hold an additional number of pages of the book, if the length of the gripping plates 13 and 23 no longer holds extra pages.

Example 2. A device for holding pages of books in the open position with elastic means for connecting L-shaped staples.

The device of example 2 shown in FIG. 5-8, includes two identical L-shaped brackets 5 and 6, including: elongated support strips 51 and 61, transverse hook-shaped bends 52 and 62, gripping strips 53 and 63 with retractable elements 55 and 65, on which three rows of teeth are made 54 and 64, respectively. All elements of the L-shaped staples 5 and 6 are made of polyvinyl chloride with the exception of teeth 54 and 64, which are made of rubber.

There is a means of connecting the support strips 51 and 61, including an elastic tape 7 of latex. At the same time, transverse grooves 56 and 66 are made at the ends of the support bars 51 and 61 for securing the corresponding ends of the elastic tape 7, the width of which corresponds to the width of the elastic tape 7. There is also a means of adjusting the tension of the elastic tape 7, made in the form of a tension buckle 8. Any suitable construction of the tension buckle 8, known from the prior art and used to tension various tapes and belts of various devices, can be used here. Therefore, the design description of the tension buckle 8 will be omitted.

The use of the device according to example 2 and the principle of its operation are similar to those described above in example 1 with a number of the following exceptions. Firstly, L-shaped brackets 5 and 6 are mounted on the cover of the book so as to be pulled together by tensioning the elastic tape 7, which is adjusted using a tension buckle 8. Secondly, if necessary, hold a relatively large amount pages of the book, the sliding elements 55 and 65 can be extended along the gripping bars 53 and 63 along them, as illustrated in FIGS. 7 and 8.

The above examples are used only to illustrate the possibility of carrying out the invention and are in no way intended to limit the scope of legal protection presented in the claims, while a person skilled in the art is relatively simple to implement other ways of carrying out the invention in the spirit and scope of the claims of this invention. inventions.
