Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a binder having a locking means for locking inside the folded base of a booklet having a folded base, and in which the booklets are bound by the locking means.

Conventionally, the locking means of this type of binder has been comprised of removable hair pin-shaped locking tools that are directly attached to both upper and lower ends of the inner back of the binder.

Then, the locking tools are attached to both ends of the binder, and at the same time, they are locked to both upper and lower ends inside the folded base of the booklet to bind the booklet.

Because of this configuration, a separate fixing device was required to prevent the hair pin-shaped locking device from being accidentally removed and to fix it without play.

In addition, since the locking tools are independent, they are difficult to handle and are easily lost.

Alternatively, there is a binder with a locking means in which a long locking rod is hooked between the upper and lower ends of the inside of the back of the binder.

However, binders with this configuration have problems in terms of strength because the locking rods are long, and the bound booklets are also easily damaged.
Furthermore, there is a drawback that handling is troublesome.

The present invention has been developed in view of the above circumstances, and it is an object of the present invention to provide a binder which eliminates the above drawbacks, has a simple structure, allows booklets to be bound securely without looseness, and is easy to handle.

This bill will be explained in detail based on the examples shown in the drawings below.
FIG. 1 is a perspective view of the present invention, and FIG. 2 is a perspective view of the same in use.

In the figure, 1°1' is the cover of the binder, 2 is the back,
The holder bases 3, 3' are inserted from both upper and lower ends inside the back part 2.
is protruding inward.

Both opposing surfaces 4, 4 of these holder bases 3, 3'

-...6,6'.

6#... is planted and formed.

The holder base 3' at the lower end is fixed, but the holder base 3 at the upper end is connected to the locking pin 5 by the base of the base 3.
A leaf spring piece 7 is extended in the same direction as ゜5', 5'', etc., and the leaf spring piece 7 is inserted into an insertion hole 8 formed at the upper end inside the back part 2 of the binder. Therefore, the holder base 3 is formed to be movable in the vertical direction.

13.13 is a stopper plate.

In addition, the movable holder base may be turned upside down,
Both may be movable.

As mentioned above, the binder locking means 9 according to the present invention is
The holder bases 3, 3' at least one of which is movable
and the locking pins 5.5', 5''...6.6', 6'
It is composed of...

Next, the case of using the binder of the present invention will be explained based on FIG. 2. First, the lower end inside the folded base 11 of the booklet 10 is locked to the locking pin 6'' of the holder base 3',
Next, the movable holder base 3 is moved up and then down to lock the locking pin 5'' to the upper end inside the folded base 11 of the booklet 10.

As a result, the booklet 10 is bound into the binder.

When removing the booklet 10, the above procedure may be reversed.

FIG. 3 shows another embodiment of the present invention, in which the leaf spring piece 7 of the movable holder base 3 is bent to form an upper piece 7a and a lower piece 7b, and the bent side surface of the lower side 7b is The overlay member 12 is fixed so that the outside surface of the overlay member 12 and the lower piece 7b can move up and down while abutting against the inside surface of the insertion hole 8.

In the case of this configuration, the prevention of rattling of the holder base 3 is more reliable than in the case of using only a simple plate spring piece.

Alternatively, although not shown, it has the same shape as the holder base 3 in FIG. 3 and has a locking pin 5 around the bent portion.
The 5', 5'... side may be configured to be swingable.

In the case of a holder base having this configuration, it is desirable to provide a protrusion at an appropriate position to prevent rattling within the insertion hole 8.

FIG. 4A and C are side and front views, respectively, of various embodiments of the locking pin, and FIG. 4A is the same as that shown in FIGS. The opening in the figure is a locking pin 5a formed by bending a rod-like body into a substantially U-shape, and the opening in the figure C is a locking pin 5b formed into a tapered tongue.

As described above, the present invention has a locking means 9 that locks inside the folded base 11 of the booklet 10 having the folded base 11.
In the binder configured to bind the booklets 10 by the locking means 9, the locking means 9 is provided to protrude inwardly from both upper and lower ends of the inside of the back 2 of the binder, and at least one of the upper and lower ends is A leaf spring piece 7 is molded to extend from the base of the holder base 3, 3' which is formed to be movable in the same direction as the locking pin, while an insertion hole 8 is formed at the corresponding end inside the back of the binder. By inserting the plate spring pieces 7 of the holder bases 3 and 3' into the insertion holes 8, the holder bases 3 and 3' are made vertically movable.

Therefore, when binding the booklet 10, the locking pin 5.5'
, 5'-...6.6', 6'-... By vertically moving the movable holder base 3 without directly handling the booklets 10, the booklet 10 can be bound securely as described above. 3 and 3' are not easily pulled out from the insertion hole 8.

Furthermore, even if the booklets are somewhat uneven in height, the holder base 3 can be reliably locked to the back of the binder without wobbling, and handling is extremely simple.
