It is provided with such a thickness that it can be easily bent with respect to 1.

The binding plate 15 is made of a thermoplastic soft resin,
It is formed of synthetic rubber, natural rubber, or the like, and is provided in a similar shape in which the planar outer shape is smaller than the main body piece 11. As shown in FIGS. 1 and 2, the binding plate 15 has a pair of engagement holes 1 provided at positions closest to both ends.
6, 17 and a pair of engagement holes 18 and 19 provided inside the engagement holes 16 and 17;
And an elongated slot hole 20 as an expansion / contraction promoting portion provided between them. Here, the engagement hole 1
The maximum distance W2 between the hooks 12 and 17 is
It is set to be smaller than the distance W1 between A and the hook 13A of the binding foot 13. That is, the engagement hole 1
The hooks 6 and 17 are set to be shorter than the distance between the hooks 12A and 13A, so that when the binding plate 15 is stretched between the hooks 12A and 13A, a tensile force is applied to both ends of the binding plate 15. The binding plate 15 can be provided to prevent the binding plate 15 from falling off.

Next, a method of using the binding device 10 according to the present embodiment will be described with reference to FIG.

FIG. 4 is a cross-sectional view showing a state in which the document D is bound by the binding device 10. First, two punch holes 21 and 22 are opened at one end of the document D with a commercially available punch or the like.
From the back of the document D, the binding feet 12 and 13 are
22 and hooks 12 from the surface of document D.
A and 13A are exposed. Next, the hook 1 of the binding foot 12
2A is inserted into the engagement hole 16 or 18 and engaged. On the other hand, the binding feet 13 are pulled while pulling the binding plate 15 so that the document D is bound with an appropriate binding force according to the binding width L.
Is inserted into the engaging hole 17 or 19 to engage. In this state, the binding plate 15 forms a closed loop together with the main body piece 11 and the binding feet 12 and 13,
As a result, the binding state of the document D is stably maintained. When the binding width L of the document D is small, the hooks 12A, 13A are
May be engaged.

Therefore, according to such an embodiment, the binding feet 12, 13 protruding from the punch holes 21, 22 of the document D.
Thus, the effect that the document D can be bound by the simple operation of bridging the binding plate 15 between the hooks 12A and 13A is achieved.

Further, since the main body piece 11 and the binding feet 12 and 13 are formed of synthetic resin, and the binding plate 15 is formed of soft resin or rubber or the like, careless hands such as metal binding tools are used. There is no pain when hit, and the work of binding the document D can be done quickly, and even if the binding feet 12 and 13 are bent, the parts are not creased and can always be restored to a certain shape and reused Is also possible.

Further, since the binding plate 15 is provided so as to be extendable and contractible, when a predetermined page is opened in a state where the document D is bound, the binding plate 15 is slightly extended to make it easy to see the vicinity of the binding margin of the corresponding page. The effect is also obtained.

The binding plate 15 has four engagement holes 16 to
Since the hooks 12A and 13A are provided with the hooks 12A and 13A by arbitrarily using one of the engagement holes 16 and 18 and one of the engagement holes 17 and 19, the binding width is reduced. It is possible to adjust the binding force minutely corresponding to the change. However, in consideration of the appearance and the balance of the binding plate 15, it is preferable to use the engagement holes having a symmetrical positional relationship.

Further, in the present embodiment, since the main body piece 11, the binding feet 12, 13 and the binding plate 15 are each formed of a thermoplastic resin or the like, a resin material which does not generate harmful gas or the like is used. When formed, it does not require so-called separate disposal at the time of disposal, and can be expected to be distributed as a product that responds to recent environmental problems.

Further, since the binding plate 15 does not require a separate member such as a stopper and has a simple configuration, the number of components can be reduced as compared with a conventional product, thereby reducing the manufacturing cost.

In the above embodiment, the binding feet 12, 13
Is illustrated and described in the vicinity of both ends of the main body piece 11, but the present invention is not limited to this, and various shapes can be changed. For example, as shown in FIGS. 5 and 6, the binding feet 12 and 13 may be continuously provided on the same plane from both ends of the main body piece 11. In use, the binding feet 12, 13
May be bent and used as a posture standing upright from the main body piece 11. Further, a linear reinforcing rib 25 or a lattice-like rib (not shown) may be provided on the back side of the main body piece 11. According to this, even when the binding feet 12 and 13 are bent or the binding width increases, the planar posture of the main body piece 11 can be stably maintained. Note that these ribs are also applicable to the above embodiment.

Further, the expansion / contraction promoting portion of the binding plate 15 in the above embodiment is not limited to the slot hole 20, but may be any shape that promotes the expansion / contraction of the binding plate 15 such as a shape narrower than other portions. Good.

Further, the binding plate 15 in the above embodiment is
Although four engagement holes 16-19 are formed, two or more engagement holes may be formed. For example, when three or more engagement holes are formed on one side, a total of six or more engagement holes can be formed, so that a binding width adjustment region in which a substantially constant binding force can be applied can be enlarged. Further, rubber bands or the like can be used as the binding members instead of the binding plates 15.

Further, the binding feet 12, 1 in the above embodiment are used.
3 has one hook 1 on each of these tip sides.
Although 2A and 13A are provided, hooks extending over a plurality of stages may be formed. This also achieves the same effect as when a plurality of engagement holes are provided.

[0030]

As described above, according to the present invention,
Documents can be bound by a simple operation of hanging a binding member over a hook provided on the binding foot. Also, since the main body piece and the like are formed of synthetic resin, there is no need to pay much attention to handling like a metal binding tool, and the work of binding documents can be performed quickly, and even if the binding foot is bent. The part can always be restored to a constant shape without being creased, and long-term use is also possible. Further, since the binding member can be expanded and contracted, when a predetermined page is opened in a state where the document is bound, the binding plate can be slightly elongated, so that the vicinity of the binding margin of the predetermined page can be easily seen.

Further, since the binding member is provided with an engagement hole relatively disposed at a position shorter than the distance between the hooks of the pair of binding feet, when the binding member is hooked on the hook,
The pair of binding feet are pulled so as to approach each other, so that the binding state can be stably maintained without the need for a stopper or the like, and the cost can be reduced by reducing the number of parts. Further, if a plurality of engagement holes are formed, the binding force can be made substantially constant even when the binding width changes, and the change in the binding width can be easily dealt with.
