As shown in FIGS. 2 and 3, one end of, for example, two binding rods 34 is fixed to the inner surface of the first movable plate 26 at predetermined intervals in the longitudinal direction thereof. Is done. The binding rod 34 is to be inserted into a binding hole of a document or the like for binding. When the first movable plate 26 is erected perpendicularly to the substrate 14, the binding rod 34 is spaced apart from the second movable plate by a predetermined distance above the substrate 14 as shown in FIG. It is formed so as to extend parallel to the substrate 14 toward 28. The binding rod 34 is formed in a hollow pipe shape so that the rod-shaped member 36 can be housed therein so as to be freely inserted and removed. Further, as shown in FIG. 9, the distal end of the binding rod 34 is cut out substantially obliquely so as to fit with the receiving portion 38 a formed on the pressing plate 38. The rod-shaped member 36 is formed in a substantially U-shape, and a holding plate 38 is disposed on the side opposite to the first movable plate 26 so as to be substantially orthogonal to the binding rod 34 and to face the first movable plate 26. Is done. Then, as shown in FIG. 2, the rod-shaped member 36 penetrates the pressing plate 38 in the thickness direction from the side opposite to the first movable plate 26, and extends to the pressing plate 38 in a state of extending toward the first movable plate 26. It is attached.

At the time of a binding operation of a document or the like, first, the pressing plate 38 and the rod-shaped member 36 are separated from the binding rod 34. Next, a document or the like to be bound is inserted from the open end side of the binding rod 34. Then, the rod-shaped member 36 is inserted into the binding rod 34, and the open end side of the binding rod 34 is closed by the pressing plate 38. Next, the first movable plate 26 is raised from the state shown in FIG. 2 to the state shown in FIG. 1, and the pressing plate 38 is arranged inside the second movable plate 28. At this time, by turning the second movable plate 28 outward, the pressing plate 38 can be introduced between the locking piece 28a and the base material 14.

In this embodiment, the locking piece 28a is formed so as to engage with a portion of the rod-shaped member 36 attached to the pressing plate 38, which extends in parallel with the pressing plate 38. When taking out a filed document or the like, the document can be taken out by performing an operation reverse to the above.

The file 10 includes a fixture 18 having a substantially U-shape. The fixture 18 is formed, for example, by bending a metal wire having a circular cross section into a substantially U-shape.
As shown in FIG. 10, it is composed of two insertion portions 18a and a connection portion 18b connecting one end thereof. However, it is not limited to a metal one. Insertion part 18 of fixture 18
As shown in FIGS. 2 and 3, a is inserted into the fixture insertion hole 114 of the connecting projection 112 protruding toward the front side of the substrate 14.
The binding device 12 is inserted so as to extend substantially in parallel with the surface of the substrate 14 from one end side to the other end side in the longitudinal direction. In this case, the length of the insertion portion 18 a is formed larger than at least the maximum opening length of the connection hole 16 in order to prevent the connection protrusion 112 from coming out of the connection hole 16 without permission. Note that the maximum opening length is the maximum length of the opening of the connection hole 16, the diagonal length of the opening when the connection hole 16 is rectangular, and the diameter when the connection hole 16 is circular. . Further, since the connecting portion 18b is formed so as to extend outside the fixing tool insertion hole 114 of the connecting protrusion 112, it can be used as a tab when the fixing tool 18 is attached / detached. That is, by holding and hooking the connecting portion 18b as a tab portion, the fixing member 18b is operated.
Can be easily inserted and removed. Further, the connecting projections 11 fitted at predetermined intervals in the longitudinal direction of the substrate 14 are provided.
2, the fixture insertion holes 114 are formed so as to linearly communicate with each other in the longitudinal direction of the substrate 14, so that the fixture 18 can be easily inserted and removed by a linear operation. Therefore, the operation at the time of connecting the binding device 12 to the file cover 100 or at the time of separating the binding device 12 is easy.

As shown in FIGS. 2, 3 and 9, the surface of the substrate 14 has a fixture support groove for supporting the fixture 18 when it is completely inserted into the fixture insertion hole 114. 20 is formed in a substantially U-shape when viewed from the front, corresponding to the fixture 18. As shown in FIG. 4, the cross-sectional shape of the fixture support groove 20 is formed by denting the surface of the substrate 14 into, for example, a substantially semicircular shape corresponding to the cross-sectional shape of the fixture 18. Therefore, the fixture 18 is supported so as to fit into the fixture support groove 20. For this reason, the fixing device 18 is unlikely to come out without permission, and the fixing device 18 is unlikely to be in the way when a document or the like is bound to the binding device 12.

Further, on the surface of the substrate 14, the board 14 of the fixture 18 when completely inserted into the fixture insertion hole 114 is provided.
A locking projection 22 is formed as locking means for locking the outside as viewed from the center. The locking projection 22 is shown in FIG.
As shown in (A), the connecting portion 18b of the fixture 18 is formed to protrude in the thickness direction from the surface of the substrate 14 so as to abut on the outside as viewed from the center of the substrate 14. Locking projection 22
Is formed in a rectangular shape long in the width direction of the substrate 14 along the connecting portion 18b as shown in FIG. By forming the locking projection 22, the movement of the fixture 18 coming out of the fixture insertion hole 114 is restricted, and the fixture 18 can be prevented from coming out without permission. Further, in this embodiment, since the fixing tool 18 is fitted into the fixing tool supporting groove 20, the height of the locking projection 22 from the surface of the substrate 14 is not so high. Movement can be regulated.

Further, as shown in FIG.
A recess 24 that is at least larger than the thickness of the fixture 18 is formed through the substrate 14 in the thickness direction inside the locking projection 22 when viewed from the center of 4. By inserting the object M into the concave portion 24 and digging (prying), even when the fixing tool 18 is relatively firmly locked by the locking means, it is easy to release the locking relatively easily. That is, the recess 24
For example, the fixture 1 is inserted by inserting a tool M such as a flathead screwdriver or an object M such as a coin, and
8 is to be removed. That is, FIG.
As shown in FIG. 11, by inserting the object M into the concave portion 24 and making a gouge, the inner edge of the concave portion 24 becomes a fulcrum, and the vicinity of the lower side of the fixture 18 becomes an action point, as shown in FIG.
With the leverage principle, the fastener 18 can be relatively easily moved over the locking projection 22 to release the engagement. After this,
The fixing device 18 can be removed from the binding device 12 by pulling out the fixing device 18 from the fixing device insertion hole 114 as shown by a two-dot chain line in FIG. Therefore, this file 10
Is a fixture 18 even though it can be discarded separately.
And the binding device 12 can be firmly fixed, so that documents and the like can be securely held, and are strong and excellent in durability. The object M to be inserted into the recess 24 is not limited to a coin or a flathead screwdriver, but may be anything as long as it can make a gap between the case and the binding member. However, the concave portion 24 has at least the object M to be inserted.
Must be sized so that a gap greater than the thickness of the fastener 18 opens between the fixture 18. In addition, in the binding device 12, as shown in FIGS. 3, 9, and 11, both ends in the width direction of the concave portion 24 on the front surface side of the substrate 14 are obliquely cut away from the rear surface side of the substrate 14 to the front surface side. Concave part 24
Is formed to have a tapered portion 24a whose width is increased. Since the tapered portion 24a is formed, the concave portion 24
It is easy to insert object M into

Further, in the binding device 12 of the file 10, as shown in FIGS. 3 and 11B, locking shoulders 40 are formed on both sides in the width direction of the recess 24 as another locking means. You. As shown in FIG. 11A, the locking shoulder portion 40 is formed so as to protrude in the thickness direction from the surface of the substrate 14 so that the connecting portion 18b of the fixing tool 18 abuts inward when viewed from the center of the substrate 14. You. When the inside of the connecting portion 18b of the fixture 18 is brought into contact with the locking shoulder 40, the fixture 18
Can no longer be inserted inside, and the fixture support groove 20
Will fit within. That is, as shown in FIG. 11A, the connecting portion 18b of the fixing tool 18 of this embodiment is sandwiched from both sides by the locking projection 22 and the locking shoulder 40 so that the fixing tool supporting groove 20 is formed. Supported within. As can be seen from FIG. 11, the fact that the locking projection 22 and the locking shoulder 40 protrude from the surface of the substrate 14 in this embodiment is a description based on the bottom of the fixture support groove 20. .

When the binding 12 and the file cover 100 are connected, the file cover 10 is inserted into the connection hole 16 of the binding 12.
No. 0 connecting protrusion 112 is fitted into the fixing member insertion hole 114 of the connecting protrusion 112 protruding toward the front surface side of the substrate 14.
The fixture 18 is inserted so as to extend substantially parallel to the surface of the fixing member 4. Then, the fixture 18 is simultaneously supported by the inner surface of the fixture insertion hole 114 and the surface of the substrate 14. As a result, the fixing device 18 acts like a bar, the connecting projection 112 is fastened to the spine 102 by the fixing device 18, and the binding device 12 and the file supervisor 100 are connected. . At this time, the substrate 14 is positioned with respect to the thickness direction of the spine portion 102, and the movement of the substrate 14 in the thickness direction of the spine portion 102 is regulated.
12 does not come out of the connecting hole 16 without permission. Also,
Since the fixing tool 18 is locked by the locking projection 22, the fixing tool supporting groove 20, and the locking shoulder 40, the fixing tool 18 comes out of the fixing tool insertion hole 114 without permission unless the user intentionally removes it. Never. When discarding or the like, if the user intentionally detaches the fixture 18 from the locking projection 22 and pulls it out from the fixture insertion hole 114, the file cover 100
Can be easily pulled out from the connection hole 16 of the binding device 12, so that the binding device 12 and the file cover 100 can be easily separated. Further, according to the configuration of the file 10 according to the present invention, since the binding device 14 and the file cover 100 can be easily connected, assembly at the time of manufacturing is easy, and further, for example, only the file cover 100 is replaced. It is also easy to use.

The file 10 shown in FIG. 1 is composed of the first file on both sides in the width direction of the binding device 12 when the file cover 100 is closed.
Of the movable plate 26 and the second movable plate 28
And a storage recessed portion 116 for storage on both sides in the width direction on the inner surface of the back cover 110.
The storage recess 116 is formed by recessing the inner surface of the file cover 100 into a shape corresponding to the first movable plate 26 and the second movable plate 28 as shown in FIGS. Therefore, when the file cover 100 is closed, as shown in FIGS. 3 and 4, the first movable plate 26 and the second movable plate 28
Are stored inside the front cover part 108 and the back cover part 110, respectively. Therefore, the width of the file 10 can be reduced.

Moreover, the spine portion 102 of the storage recess 116 is provided.
Is formed as a supporting edge 116a that comes into contact with an end of the binding device 12 opposite to the spine 102 on both sides in the width direction. The support edge 116a is formed to extend in a direction substantially orthogonal to the surface of the adjacent file cover 100. In addition, the ends opposite to the spine portion 102 on both sides in the width direction of the binding device 12 correspond to the side edges 27 of the first movable plate 26 and the second movable plate 28 opposite to the substrate 14. That is. In this file 10, as shown in FIG.
When the binding 12 is closed and the binding device 12 is turned downward in the vertical direction, the side edges 27, 27 of the first movable plate 26 and the second movable plate 28 are respectively supported by the support edge 116a in FIG. It is received and supported from below. Therefore, the load on the cooperating portion of the substrate 14, the connecting protrusion 112, and the fixture 18 can be reduced, and a more robust file can be obtained.

As shown in FIG. 6, the file 10 has a file cover 100 from the support edge 116a.
Is formed so that the thickness gradually decreases toward the edge portion of. That is, since the thickness d1 of the file cover 100 at the portion where the supporting edge 116a is formed is formed to be thicker than the thickness d2 of the peripheral portion of the file cover 100, the strength of the supporting edge 116a increases. In addition, since the thickness of the portion other than the supporting edge 116a can be reduced, the overall weight can be reduced.

In the description of the embodiment of the present invention,
Although the description has been given of the one having two binding rods, the present invention is not limited to this, and the present invention can be applied to the one having two or more binding rods similarly to the above. In the above-described embodiment, a so-called pipe-type binding device has been described. However, the present invention is not limited to this, and can be similarly applied to other types of binding devices. Alternatively, the connecting protrusion may be formed on the binding tool, the connecting hole may be formed on the file cover, the connecting protrusion may be fitted into the connecting hole, and fastened by a fixing tool as described above.
