Description

[Detailed explanation of the invention] (Industrial application field) The invention is a method for converting books such as diaries, ledgers, notebooks, scrapbooks, periodicals such as quarterly and seasonal publications, and other books into a certain number of books. This relates to a synthetic resin connecting tool for connecting together.

(Prior Art) Diaries, ledgers, notebooks, scrapbooks, periodical magazines such as quarterly, monthly, seasonal, etc., and other books can be divided into multiple types depending on their content, publication date, production date, etc. Since it is convenient for organizing and using books to connect the volumes together, binding is now done by full-scale binding, or simply by binding with strings.

(Problems to be Solved by the Invention) However, binding using full-scale binding as described above is expensive, and binding using strings, although simple, is not desirable in terms of appearance.

(Means for solving the problem) The present invention was devised in view of the above points, and its purpose is to create a strong structure by simply connecting multiple members of the same configuration. The purpose is to easily create a good-looking combined book. In other words, in order to easily and neatly combine multiple volumes of ledgers or books, and sometimes to separate them, an adhesive layer is applied to one side of the prismatic body, and an adhesive layer is applied to the other side perpendicular to this. is provided with a concave groove with a narrow entrance in the longitudinal direction, and a convex ridge with a narrow base in the longitudinal direction on a surface symmetrical to the surface of this concave groove, and these concave grooves and convex ridges are both the same. The grooves are formed so that the width becomes narrower in the direction, and the concave grooves are large enough to fit the convex grooves tightly over the entire length, so that they can be combined by using multiple grooves. It is composed of

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

The connection device for notebooks and books of the present invention is used by being adhesively fixed to the back cover a of notebooks and books, and multiple devices of the same configuration are required for connection, but regarding the configuration will explain one piece.

For example, a quadrangular prism A made of a synthetic resin such as an acrylonitrile butadiene-styrene copolymer resin is injection-molded, and an adhesive layer 1 made of a synthetic resin is provided on one surface, and one surface perpendicular to this surface is provided with an adhesive layer 1 made of a synthetic resin or the like. for,
A concave groove 2 is formed in the longitudinal direction, and a convex ridge 3 is formed in the longitudinal direction on another surface symmetrical to the surface of the concave groove 2.

The concave groove 2 is a triangular dovetail groove with a narrow entrance 4, and the convex groove 3 is a triangular dovetail groove with a narrow base 5. The concave grooves 2 and the convex ridges 3 have shapes that become narrower or narrower from one end surface 6 toward the other end surface 7.
The size of the protrusion 3 is such that when the protrusion 3 is inserted from the end face 6, the protrusion 3 does not loosen and is tightly fitted over its entire length.

A minimum of two quadrangular prisms A with the above configuration are required, and in the case of more than that as shown in FIGS. Alternatively, the concave grooves 2 are unnecessary, so there is no need to provide them.

Note that the grooves 2 and the protrusions 3 may have circular cross sections, as shown in FIG. Further, the quadrangular columnar body A can also be formed of metal.

(Function) When connecting ledgers and books using the rectangular prism A having the above configuration, a minimum of two pieces are required, so when using the rectangular prism A The synthetic resin paper of the adhesive layer 1 is peeled off, and this is adhesively fixed to the back cover a of a notebook or book. In this way, convert the quadrangular prism A to the spine a
This is connected to another one in which a rectangular prism A is similarly adhesively fixed to the back cover a.
is inserted from its lower end surface 7 side into the concave groove 2 of the other square columnar body A from its upper end surface 6 side, and is inclined over the entire length from the upper end surface 6 to the lower end surface 7 of each other. Connect by inserting it tightly.

In this case, even if concave grooves 2 or convex ridges 3 appear on the outer surface of the quadrangular prism-like body A on both sides in a connected state, this will not impede the connecting action in any way, but from an aesthetic point of view, It is preferable that no convex ridges 3 or concave grooves 2 appear on the outer surface, as in the quadrangular prisms 8 and 9 at both ends shown in FIGS. 3 and 4.

Another connection order may be to first connect a plurality of rectangular prisms A, and then adhesively fix the back cover a of a notebook or book to the adhesive layer 1 of each rectangular prism A.

(Effects of the invention) As explained above, the rectangular prisms that make up the connector have an extremely simple structure, but the invention allows for extremely simple connection by using a plurality of them. Since it can be combined and disassembled as necessary, the number of combined items can be increased or decreased as desired, and the combined state is as follows:
Since it is carried out over the entire length of the rectangular prism, it is extremely strong and reliable, and since the rectangular prism is connected as a whole, it forms a single plate, making it possible to stabilize the paper sheet. It can be unveiled and has a good appearance.
