Description

[Detailed description of the invention] The invention includes a holder base projecting inward from both upper and lower ends of the inside of the back of the binder, and a plurality of locking blades protruding from both opposing surfaces of the holder base. The present invention relates to an improvement in a binder configured to bind bound articles such as booklets by locking the locking blade inside the folded base of the bound articles.

Conventional binders of this type include those shown in FIGS. 1 and 2, for example.

That is, one holder base A is rotatably attached, the other holder base B is fixedly attached, and the lower end inside the folded base of the binding material C is first attached to the locking blade of the holder base B. After locking the binding blades F, F, etc., the binding material C is held upright, and then the holder base A is rotated and the locking blades F, F,... are fixed to the folded base of the binding material C. Insert and lock the upper end of the inner side, and then insert the rotation stopper G.
is inserted into the insertion hole H, and the rotation stopper G is inserted into the holder base A.
It was fixed by making it come into contact with the rear surface of the paper, thereby binding the bound article C.

I, I' indicate the cover of the binder, and J indicates the back.

However, in such a configuration, the bound book C is simply bound to the binder using the upper and lower locking blades E, E,..., F, F,..., so it cannot be left standing on the bookshelf. There is no problem when the binder is in use, but when using the binder, especially when examining Binding C while it is still bound,
Locking blade E, E,...,F.

There was a drawback that the entire load of the binding material C was concentrated on F, . . ., deforming the locking blades E, E, . . ., F, F, .

This locking blade E, E. . . , F, F, . . . are generally formed with a thin plate thickness in order to reduce frictional resistance, so the deformation is relatively easy to occur.

In addition, the binding operation was troublesome because the orientation of the bound article had to be adjusted visually each time in order to properly lock the bound article with the opposing upper and lower locking blades.

The present invention has been developed in view of the above circumstances, and by providing a binding thickness guide parallel to the locking blade and sandwiching the locking blade from both sides in the vicinity of at least one of the holder bases, the locking blade can be tightened. The purpose is to provide a binder that can prevent deformation and is easy to bind.

Hereinafter, the present invention will be explained in detail based on the embodiments shown in the drawings.

FIG. 4 is a perspective view showing an embodiment of the binder according to the present invention, and FIG. 5 is an exploded perspective view of the main parts.

In the figure, 1 and 1' are the cover of the binder, 2 is the back part, and a mounting body 4 having an insertion hole 3 at the upper end inside the back part 2.
is installed.

A holder base 6 is rotatably attached to the upper edge of the front side of the attachment body 4 by means of a hinge 5.

The holder base 6 has locking blades 8, 8 . on a surface 7 facing the other holder base described later. ... is formed protrudingly,
The locking blades 8, 8 .
...A rotational force is applied in the opposite direction.

At the tip of the holder base 6, locking protrusions 10, 10' are formed in the opposite direction to the locking blades 8.8, .

Reference numeral 11 denotes a push fixture for rotating and fixing the holder base 6 by pushing the same.

The pushing fixture 11 consists of a horizontal holding part 12 and a vertical part 13 that extends downward from the base end of the holding part 12, and the holder base 6 is engaged with the distal end of the horizontal holding part 12. Locking portions 14, 14' are provided to which the protrusions 10, 10' lock.

15 is an opening, and when the push fixture 11 is inserted into the insertion hole 3 of the mounting body 4, the opening 15 is locked by a curved locking piece 16 integrally formed at a corresponding position of the mounting body 4. This is for fixing the pushing fixture 11.

Reference numeral 17, 17' indicates a binding thickness guide according to the present invention, and the binding thickness guide 17, 17' has the locking blades 8, 8, . ... and parallel to the relevant locking blades 8, 8.・・・
・It is installed so that it is sandwiched from both sides.

It is desirable for handling that the protruding dimension is approximately the same as that of the holder base 6.

In the illustrated embodiment, the plate-like body is bent into a U-shape and the rising portions thereof are configured as binding thickness guides 17 and 17', but it is of course possible to form them separately. It is.

The binding thickness guides 17, 17' are connected to the connecting portion 1.
8 is sandwiched between the binder back 2 and the mounting body 4.

A stopper piece 19 is provided upright near the center of the connecting portion 18, and a stopper piece 20 is also provided at a corresponding position at the tip of the vertical portion 13 of the pushing fixture 11. The locking of the stopper pieces 19 and 20 prevents the pushing fixture 11 from being accidentally pulled out.

Also, set the tip of the binding thickness guide 17.17' to the cover 1°1'.
By bending to the side, it is formed so as not to damage the binding.

A holder base 21 is fixedly attached to the lower end inside the back part 2.

Locking blades 22, 22, .
Similar to 17', binding thickness guides 23, 23' are provided.

In the illustrated embodiment, a single plate-shaped body is bent and formed integrally with the holder base 21, but of course they may be separate bodies.

Next, the operation of the present invention will be explained.

Place the cover of the first bound item (not shown) on the lower binding thickness guide 23.
(or 23') so that the locking blade 22
．． 22'..., then the cover is brought into contact with the upper binding thickness guide 17 (or 17'), and then,
By moving the push fixture 11 downward, the holder base 6
is rotated, and the locking blades 8, 8°... are inserted and locked inside the folded base of the bound article to bind the bound article.

When using the binder with bound materials bound, the entire load of the bound materials is transferred to both the upper and lower locking blades 8, 8.・・・
・, 22, 22... Do not concentrate on the binding thickness guide 17.1
7', 23, and 23' are also dispersed.

For this reason, both locking blades 8, 8°..., 22, 22. ...
deformation can be prevented.

In the above embodiment, there are binding thickness guides near both holder bases 6 and 21. ? , 17'.

Although the case where 23 and 23' are provided is shown, they may be provided only near one of them.

As described above, the present invention has the locking blades 8, 8°..., 22, 2 near at least one of the holder bases 6, 21.
2. This binder is provided with binding thickness guides 17.17' and 23.23' that are parallel to and sandwich the locking blade from both sides.

Therefore, the entire load of the silk material is applied to the locking blades 8, 8. ..., 22,
22. Don't concentrate on the binding thickness guides 17, 17',
23, 23', so the locking blade 8
,8. ..., 22.22. ...is not deformed.

In addition, the binding operation is also performed using the binding thickness guide 17.17'.
23. Just by lightly touching the cover of the binding material to 23', the opposing upper and lower locking blades 8, 8. ..., 22.2
2. It is possible to lock correctly with ..., and it is easy to bind because there is no need to measure by eye like in the past.
