Description

[Detailed description of the invention] The present invention consists of a binding section for binding together multiple sheets of paper such as albums and sample books, pieces of cloth, etc., a cover that covers the binding section, and an insert for attaching a case-type cover. The present invention relates to a binding device whose parts are integrally formed of synthetic resin.

The purpose of this invention is to cover the binding section and cover,
An object of the present invention is to provide a binding device that simplifies the attachment of a cover and a case-type cover by integrally forming an insertion part for attaching a case-type cover, and that also makes the production extremely easy and has a good appearance. It is something to do.

The second embodiment of the present invention will be described below.
As shown in the figure, the binding device A has a back wall 2 at one end of the connecting wall 1, and side walls 3, 3 following the back wall 2 in parallel,
A plurality of through holes 4, 4 are bored facing the side walls 3, 3, and projecting peripheral walls 5, 5 are formed on the outer peripheral surfaces of the through holes 4, 4.
At the other end of the connecting wall 1, there is a thin connecting wall 7 having a bifurcated curved shape.
7, facing the tips of the walls 7, 7 and having a round-shaped cross section and openings 8, 8 on the outside;
The inserting portions 10 are provided in parallel with each other, and the entire structure is integrally formed of elastic synthetic resin such as polypropylene.

The cover bodies 11, 11, which are covers, case-type covers, etc., that fit into the insertion parts 10, 10 are made of synthetic resin, and as shown in FIGS. 3 to 6, the upper and lower cover bodies 11, 11 are made of synthetic resin. Same shape, right side wall 12 of cover body 11
has a fitting protrusion wall 13 having the same shape as the fitting groove 9, a protrusion 14 is formed inside the fitting protrusion wall 13, and an inclined concave wall 15 is formed parallel to the outside. As shown in FIG. 9, an engaging protrusion 18 is provided on the inner front surface of the left side wall 16 of the upper cover body 11, and a fitting hole 17 is provided on the inner side of the lower cover body 11.

The above-mentioned cover bodies 11 are all made of synthetic resin and are case-type, and have a fitting hole 17 and a protruding engagement portion 18 provided in the left side walls 16, 16 of the upper and lower cover bodies 11, 11.
The structure is such that it is polymerized and locked.

As shown in FIG. 10, the shape of the fitting protrusion wall 13 on the right side wall 12 of the cover body 11 is the same as that in the above case, and the cover body 11 is formed into a plate shape.
It is also possible to attach a tying cord 21 to the left end of the cover body 11, and to connect the upper and lower cover bodies 11, 11 with the cord.

Next, if we explain how to use this invention, the second
As shown in the figure, a fitting protrusion wall 13 is formed on the right wall side 12 of the cover body 11 in the fitting grooves 9, 9 of the fitting part 10.
After fitting the thin connecting walls 7, 7 as shown in FIG.
If it is reversed inwardly, the state as shown in FIG. 9 will be obtained.

In addition, in the binding section 6, a piece of paper 19 with a binding hole provided in advance on the right end is held between the side walls 3, 3, and the through holes 4, 4 are inserted.
Fasten through the female and male screws 20.

Note that instead of the female and male screws 20 described above, a single binding string may be passed through the through holes 4, 4 to fasten the pieces of paper 19.

As explained above, the present invention covers the cover bodies 11, 11.
The bifurcated curved thin connecting walls 7, 7 having the fitting parts 10, 10 for attaching the cover members 11, 11 have the effect of always returning outwards because the thin connecting walls 7, 7 are inverted inward and have a threading action. Then, the cover body 11 is made as shown in Fig. 9.
It can be opened 180 degrees to view the paper strip 1 in the storage section 6.
It has excellent effects such as making it easier to spread the contents pasted on 9.

Also, a fitting part 1 that fits the binding part 6 and the cover body 11
0 is connected to the connecting wall 1 and the bifurcated thin connecting walls 7, 7, which are integrally molded with synthetic resin, so the number of parts is small, assembly is easy, and the product with a good appearance on the back is inexpensive. can be provided to

Since the invention has the above-mentioned functions and effects, the present invention has a wide range of applications such as albums, sample books, photo negative film, diaries, scrapbooks, fabric sample books, etc.
