Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a file, and more particularly, to a file that includes a cover having a front cover, a back cover, and a spine, and a binding tool attached to the cover.

(Prior Art) Conventionally, a binding device is attached to the spine of the cover, and includes a board fixed to the spine, and a swing plate having a binding body and pivotally connected to the board via a hinge. It is known that binding holes for paper sheets are inserted into the binding body to bind the paper sheets.

The size of the front cover and back cover of the cover is formed to be larger than the size of the paper sheets to be bound, and when the cover is closed, that is, when the front cover and the back cover are overlapped, the paper sheets is completely covered by each of these covers.

(Problem to be solved by the invention) However, a file with paper leaves bound in a binding tool is
Normally, it is stored vertically on a shelf, but
The sheet of paper is supported by the binding tool only on one side, and the other side is free, and since the cover is formed larger than the sheet to be bound, the other side that is free is , it is floating relative to the edge of the cover.

Therefore, all the weight of the paper sheet acts on the binding tool, and the binding tool and the cover to which the binding tool is attached bear the weight, and as a result, after long-term use, There were problems in which the hinge part of the binding tool was damaged and the edges of the front and back covers of the cover were damaged.

SUMMARY OF THE INVENTION An object of the present invention is to make it possible to directly load the weight of paper sheets when stored vertically on a shelf, thereby solving the above-mentioned problems and improving durability. To provide a file in which the binding direction of the paper sheets is not inclined with respect to the cover when unfolded, and therefore, even when writing on the paper sheets in a bound state, it is possible to write easily. be.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention provides folds 2d and 2e at the base end sides of the front cover 2a and the back cover 2b in the longitudinal direction on the back cover 2c. The binding device 3A, 3B consists of a cover 2 which is connected to the cover 2 so as to be openable and closable through the cover 2, and binding tools 3A, 3B attached to the cover 2. The substrate 31 is pivotally attached via a hinge portion 32, and when the front and back covers 2a, 2b are closed, the substrate 31
When the cover 2 is erected at the hinge portion 32 with the front and back covers 2a and 2b closed, the file is provided with a rocking plate 33 that bends against the rocking plate 33, and the binding body 4 is attached to the rocking plate 33. , the upper free end in the width direction of the cover 2 of the rocking plate 33, which is bent with respect to the substrate 31, is on the free end in the longitudinal direction of the front and back covers 2a, 2b with respect to the lower free end in the width direction. The lower edge of the free end side of the sheet to be bound into the binding body 4 is displaced greatly to the front and back covers 2a,
The present invention is characterized in that it includes a rocking plate displacement means that can be positioned at or near the lower edge of the free end side of 2b.

(Function) When the cover 2 is closed and stored vertically on a shelf, the amount of displacement of the upper free end of the cover 2 in the width direction of the swing plate 33 that bends with respect to the board 31 is reduced in the width direction. Since the amount of displacement is larger than that of the free end on the lower side, the paper sheets bound into the binding tools 3A and 3B are inclined with respect to the cover 2 as shown by the chain line in FIG. is located at the same position as the lower edge of the front and back covers 2a, 2b of the cover 2, or slightly protrudes downward, so that the weight of the paper sheet is supported by the shelf in which it is stored.

As a result, the weight burden on the binding tools 3A, 3B and the front and back covers 2a, 2b is reduced, and the decrease in durability due to the weight burden can be eliminated.

Then, when the cover 2 is taken out from the shelf and unfolded on the desk, the edges of the paper sheets can be made parallel to the edges of the cover 2 without being inclined to the cover 2 as shown in FIG.
Even when writing on the paper sheet, the work can be done easily.

(Embodiment) What is shown in the drawing is a continuous slip paper file in which a continuous slip paper 1 having a large number of sprocket holes 1a on both sides is bound through the sprocket holes 1a. Fold part 2 at the base end in the length direction of back cover 2b and back cover 2c.
A cover 2 made of cardboard or the like is connected so as to be openable and closable via d and 2e, and a substrate 31 is fixed to the inner surface of the spine 2c of the cover 2, and a substrate 31 is attached to one side of the substrate 31 in the width direction of the cover 2. A pair of synthetic resin binding devices 3A and 3B are attached, which are pivotally connected via an extending hinge portion 32 and include a swing plate 33 that bends with respect to the base plate 31 when the front and back covers 2a and 2b are closed. The spelling rod 4 is held upright on the swing plate 33 so as to be swingable.

The binding tools 3A, 3B are independently attached to two places, upper and lower, on the inner surface of the spine 2c, and the swing plates 33 of each of these binding tools 3A, 3B,
33 includes a rod-shaped top plate 5 made of metal and having a U-shaped cross section.
are connected to each other via the upper plate 5.
3 and 33 are connected.

As shown in FIG. 10, this upper plate 5 engages with the base side of the spelling rod 4 at both ends in its length direction, so that the spelling rod 4
A regulating hole 5a consisting of a long hole that only allows tilting of the cover 2 to both sides in the width direction is formed, and the upper plate 5
A notch 5b is formed in one side wall of both ends in the length direction, into which the swing plate 33 is inserted from the side, and both ends of the upper plate 5 are inserted into each swing plate 33 on the upper surface thereof. They are connected by a connecting means such as a fitting eyelet fitting. Although the binding tools 3A and 3B are formed separately and connected by the upper plate 5, they may be formed integrally.

In addition, the binding tools 3A and 3B are both provided with the hinge portion 32 between the base plate 31 and the swing plate 33, but each hinge portion 32 in the binding tools 3A and 3B is As shown in Figures 2 and 3, the positions of the thin portions 32a, 32a are reversed. That is, among the binding tools 3A and 3B, when the cover 2 is vertically erected, the hinge portion 32 of the upper binding tool 3A located above in the width direction is
As shown in FIG. 2, the thin part 32a is formed so as to be located away from the spine 2c, and the hinge part 32 of the lower binding tool 3B located below is
As shown in FIG. 3, the thin portion 32a is formed at a position close to the spine 2c.

Thus, the spine 2c has front and back covers 2a,
2b through folded parts 2d and 2e, and the substrate 31 is arranged so that the hinge part 32 is displaced to a position closer to the center of the spine 2c than the folded part 2e. It is fixed to the spine 2c, and the spine 2c is connected to the front and back covers 2a, 2b.
When the substrate 31 is vertically erected as shown by the dotted line in Figures 2 and 3, the swing plate 33 is displaced toward the free ends in the longitudinal direction of the front and back covers 2a and 2b. That's what happens.

Therefore, the hinge portion 3 of each binding tool 3A, 3B
By configuring 2 as described above, when the cover 2 is erected with the front and back covers 2a, 2b closed, the front and back covers 2a, The amount of displacement toward the free end in the longitudinal direction of 2b is larger than the amount of displacement of the swing plate 33, which bends with respect to the base plate 31 of the lower binding tool 3B, toward the free end in the longitudinal direction of the front and back covers 2a and 2b. As a result, the free end side of the paper 1 bound into the binding rod 4 is inclined downward as shown by the chain line in FIG. It is located at the same level as the lower edge, and when the cover 2 is vertically erected and stored on a shelf, the weight of the paper 1 is supported by the shelf.

Therefore, the weight burden acting on the front and back covers 2a, 2b and binding tools 3A, 3B is reduced.

Moreover, in the above configuration, each of the binding tools 3
The spelling rod 4 in A, 3B is the swing plate 3
3, and a presser body 6 facing the upper plate 5 is inserted into and removably inserted into each of the binding rods 4, 4 of the binding tools 3A, 3B. As shown in FIGS. 7 to 9, this presser body 6 includes a rod-like member 60 having a U-shaped cross section and a rod-like member 60 having a U-shaped cross section.
A holding body 61 made of synthetic resin is attached to both longitudinal ends of the holding body 61.
is provided with a cut groove 61a with one end open, and a holding hole 61b provided in the middle part of this cut groove 61a, to which the spelling rods 4, 4 are pivotally attached, and the cut groove 61
a is attached to the rod-shaped member 60 in a protruding manner so as to open outward from the end of the rod-shaped member 60, and the holding hole 61b is exposed at both ends of the rod-shaped member 60. A notch 6a is provided for this purpose, and a locking portion 61c is provided at the protruding end of the holding body 61.

On the other hand, a lock body 7 is pivotally attached to one side of the swing plate 33 of the binding tools 3A, 3B via a hinge part 34 in a direction perpendicular to the hinge part 32.

This lock body 7 is provided with an engagement recess 7a that removably engages with the locking part 61c, and by the engagement of the engagement recess 7a with the locking part 61c,
The holding body 61 is pressed inward to open the holding hole 61.
b is reduced in diameter so that the presser body 6 is immovably locked to the binding rod 4. As shown in FIG. 4, the engagement recess 7a of the lock body 7 is adapted to engage with the holder 61 no matter where the holder 61 is positioned on the spelling rod 4. A long engagement protrusion 7b that engages with the locking part 61c of the holder 61 is protruded from the inner surface near the opening side of the engagement recess 7a.

The lock body 7 also includes a top wall 71 and a side wall 7.
2, so that when engaged with the holding body 61 of the presser body 6, the binding rod 4 can be covered.

Further, the binding tools 3A and 3B are integrally molded mainly from synthetic resin, and at the time of this molding, the lock body 7 is also integrally molded.

Next, when the continuous slip form 1 is to be inserted into the file configured as described above, the lock body 7 is first rotated outward via the hinge portion 34 as shown in FIG. The engagement recess 7a and the locking portion 61c of the holding body 61 are unlocked. By this release, the cut groove 61a in the holding body 61 is expanded outward, that is, the diameter of the holding hole 61b is expanded,
In this state, the presser body 6 is removed from both binding rods 4.

Next, the two sprocket holes 1a on both sides of the continuous slip form 1 are inserted into the both binding rods 4. At this time, since both sprocket rods 4 can be tilted to both sides in the width direction of the cover 1 through the regulation holes 5a of the upper plate 5, one sprocket hole 1a
After inserting the sprocket into one sprocket hole 1a, the continuous slip form 1 is forced by tilting the other sprocket rod 4 inward when inserting the other sprocket hole 1a into the other sprocket hole 1a. Even without tension, insert the sprocket rod 4 into the other side sprocket hole 1a.
It can be easily inserted by matching the position.

Thereafter, the holding holes 61b of each holding body 61 in the presser body 6 are inserted into the binding rods 4, and the continuous slip paper 1 is pressed against the upper plate 5 by the presser body 6. In this case, since the diameter of the holding hole 61b is smaller than the diameter of the binding rod 4, the presser body 6 is temporarily fixed to both binding rods 4 at the insertion position by the elastic restoring force against the expansion of the cut groove 61a. Ru.

Thereafter, by swinging the lock body 7 inward and strongly pressing it, the locking portion 61c of the holding body 61 is engaged with the engagement recess 7a. This engagement presses the holding body 61 inward to reduce the diameter of the holding hole 61b, and
can be immovably locked to the binding rod 4, and the engagement of the engagement recess 7a with the locking part 61 prevents the engagement body 7 from being accidentally removed by external force from the engagement position. This prevents it from opening in the opposite direction.

In addition, the above binding is performed using two sprocket holes 1a formed on both sides of the continuous slip form 1.
The paper 1 is bound only by inserting it into the binding rod 4, but the paper 1 is held by the presser plate 6 and the upper plate 5 along its entire length on the binding side, and is in the binding state. Therefore, even if there is a large outward tensile force on the continuous form 1, the tensile force will not be concentrated on the sprocket hole 1a, and this will prevent the sprocket The hole 1a portion will not be easily torn.

Furthermore, the continuous slip paper 1 can be stapled up to the tip of the binding rod 4, and therefore the amount of continuous slip paper 1 that can be stapled relative to the height of the binding rod 4 can be increased.

Further, after the paper 1 is bound as described above, the front and back covers 2a and 2b of the cover 2 are closed and stored in a vertically standing position on a shelf, but the cover 2 is in the closed state. As a result, the swing plates 33 of each of the binding tools 3A and 3B are aligned with the front and back covers 2.
a, 2b are displaced to the free end side, and the upper binding tool 3
The amount of displacement of the swing plate 33 at A is the lower binding tool 3B.
The amount of displacement of the swing plate 33 becomes larger than the amount of displacement of the swing plate 33 at It will be supported by a shelf.

In addition, in the embodiment described above, the hinge portion 3 in the binding tools 3A and 3B is used as the swing plate displacement means.
Reverse the thin wall portion 32a of the upper binding tool 3.
Although the amount of displacement of the swing plate 33 at A was increased,
In addition, the hinge portion 32 may be inclined as shown in FIG. 11, or the upper binding tool 3A may be made as shown in FIG.
The hinge part 32 of the lower binding tool 3B
may be shifted forward or backward.

In either case, when the cover 2 is unfolded, the paper 1
The paper 1 is stored in the correct position parallel to the cover 2 as shown in FIG.
is inclined, and the weight of the cover 2 and the binding tools 3A, 3B on the paper 1 can be reduced, while the paper 1 can be held in the bound state.
This can be done easily even when writing to.

In addition, a continuous slip form 1 having a large number of sprocket holes 1a on both sides is used as the paper sheet to be bound, and a file is explained in which the two sprocket holes 1a on both sides are bound into a pair of binding rods 4. However, it goes without saying that the present invention can also be applied to pieces of paper having three or more binding holes and files having three or more binding rods. Furthermore, by forming a rough surface on the surface of the binding rod 4 by sandblasting or knurling, the binding rod 4 of the holding body 61 when locked by the locking body 7 is formed.
As a result, the holding force of the presser body 6 with respect to the binding rod 4 can be prevented from floating up from the continuous slip sheet 1, and the binding force can be further increased by binding using only the binding rod 4. This makes it possible to more reliably prevent the continuous slip form 1 from tearing from the sprocket hole 1a.

(Effect of the invention) As described above, the present invention provides the front cover 2a and the back cover 2b.
Fold part 2d on the spine 2c with the proximal end in the length direction of
The binding device 3A, 3B consists of a cover 2 connected to the cover 2 so as to be openable and closable through the cover 2e, and binding tools 3A, 3B attached to the cover 2. 31 via a hinge part 32, and the front and back covers 2a, 2b
In a file including a rocking plate 33 that bends with respect to the base plate 31 when closing, and a binding body 4 attached to the rocking plate 33, the hinge part 32 has a
When the cover 2 is stood up with the front and back covers 2a and 2b closed, the upper free end in the width direction of the cover 2 on the swing plate 33, which bends with respect to the base plate 31, becomes the lower free end in the width direction. , the front and back covers 2a, 2b are largely displaced towards the free end side in the length direction, and the lower edge of the paper sheets to be bound into the binding body 4 on the free end side is located below the free end side of the front and back covers 2a, 2b. Since it is equipped with a rocking plate displacement means that can be positioned at or near the edge, the front and back covers 2 of the cover 2
When the sheets a and 2b are closed and stored vertically on a shelf, the lower edge of the free end side of the paper sheets bound in the binding tools 3A and 3B can be supported by the shelf, and therefore the cover 2 and The weight burden of the paper sheets acting on the binding tools 3A and 3B can be reduced, and damage to the cover 2 and the binding tools 3A and 3B can be reduced and durability can be improved.
