The present invention relates to a binding device.

[0002]

2. Description of the Related Art FIG. 5 shows a cover body (1) in which the width of a spine can be freely changed according to the amount of sheets bound to the cover body.
FIG. 6 is a sectional view taken along line XX of FIG. This cover body (1) is composed of a front cover part (10) where the spine part (11) is continuous.
And a back cover part (12) having a storage part (12a) into which the spine part (11) can be freely pulled out. The piece (15) is the cover
It is formed so as to protrude inward of (1).
At the boundary between the (10) and the spine (11), a second holding piece (16)
Are formed so as to protrude so as to correspond to the first holding pieces (15).

[0003] The first holding piece (15) and the second holding piece (16) include:
Two binding holes (P ₁Position facing)
In each, a through hole (15a) (16a) is formed,
The surface of the second holding piece (16) on the side of the cover (10) is made of synthetic resin.
The reinforcement plate (17) is attached. To this reinforcing plate (17)
Locks a pair of binding bands (2) described later, respectively.
When a pair of locking projections (13) having an L-shaped cross section are formed
In addition, the through holes (15a) (16a)
A hole (17a) is formed.

A binding device for binding a sheet (P) to the cover body (1) includes a flexible band portion (20) and a stopper portion (21) provided at a base end thereof. And a pair of binding bands (2) made of synthetic resin. This binding band
(2) is formed with a pair of through holes (1) of the first holding piece (15).
5a), they are inserted from the back cover part (12) side, respectively, and are in a retaining state by the stopper part (21). Then, a band-like portion (20) projecting from the through hole (15a) toward the second holding piece (16) is attached to a binding hole (P ₁ ) provided in the paper sheet (P),
Further, the through hole (16a) of the second holding piece (16) and the reinforcing plate (17)
After being continuously inserted through the through hole (17a), each is bent toward the locking projection (13) side and locked from its open side.

[0005] Thus, the paper sheet (P) is placed on the first holding piece (1).
5) and the second holding piece (16), the binding band
By (2), it is bound in the cover (1).
In this cover body (1), the back cover part (11) is pulled out from the storage part (12a) of the back cover part (12) to expose the back cover part (10) between the front cover part (10) and the back cover part (12). The width of the spine portion (11) can be set wide, and the distance between the first holding piece (15) and the second holding piece (16) can be increased. Therefore, even if the number of sheets (P) to be stapled increases, the sheets (P) are sequentially pulled out so that the sheets (P) can be held in the first holding piece (15) and the second holding sheet (15). It is bound to the cover body (1) in such a manner that it is securely held between the piece (16). As described above, the cover body (1) having the above-described configuration can be used according to the thickness of the laminated body of the paper sheets (P), so that the cover body (1) is easy to use.

[0006]

The length of the band portion (20) of the binding band (2) used for the conventional cover body (1) as described above is such that the spine portion (11) and the back cover portion have the same length. When binding paper sheets (P) in a state where they are pulled out so that they do not fall out of the storage part (12a) of the part (12), the part protruding from the through hole (17a) of the reinforcing plate (17) is locked The length is set to be long enough to be locked to the projection (13).

As described above, in the case where the length of the binding band (2) is set to be long according to the maximum pull-out time of the spine portion (11), a large amount of sheets (P) is provided in the cover body (1). ) Is easy to use, but when not in use or a small amount of paper
When binding (P), as shown in FIG.
In addition to the inconvenience that the portion beyond the locking position of the locking projection (13) to the locking projection (13) becomes too long, this portion becomes an obstacle, and the front end of the band-shaped portion (20) is There is an inconvenience that it protrudes from the upper and lower ends and is unsightly.

Conversely, if the length of the binding band (2) is set according to the width of the spine (11) when not in use or when binding a small amount of paper sheets (P), Although the above problem is solved, when a large amount of paper sheets (P) are stapled, the through holes (17
a) The band-like portion (20) protruding from is short, so that it is difficult to lock the locking protrusion (13), and there is a disadvantage that it is easy to be inadvertently disengaged even during locking.

According to the first aspect of the present invention, a flexible binding band inserted into two binding holes provided in a sheet is inserted into the binding hole and the free end side thereof is prevented from coming off. File binding device with a configuration to be in a state "
An object of the present invention is to provide a file binding device in which the length of the binding band can be freely changed according to the amount of sheets to be bound.

[0010]

Means for Solving the Problems In order to solve the above-mentioned problems, the invention according to claim 1 of the present invention provides a method as follows.
A pair of band-shaped portions located on both sides thereof, a pair of stopper portions provided between the pair of band-shaped portions and kept in the binding hole, and a connecting piece portion connecting the pair of stopper portions. The connecting piece can be easily cut off. "

The binding band is formed in a straight line from a pair of band portions, a pair of stopper portions connected therebetween, and a connecting piece portion connecting between the stopper portions. Since the connecting piece portion can be easily cut, the connecting edges of the pair of stopper portions are forcibly separated from each other, so that the binding band becomes two binding bands each including the band portion and the stopper portion. It will be split into halves. Specifically, the connection piece can be easily cut by forming a thin portion or providing a separation means such as a perforation.

When binding a small number of paper sheets with this binding device, the binding piece is not cut and used as a single binding band. In this case, the leading ends of the band portions on both sides of the binding band are communicated with the two binding holes of the sheet, respectively, and after insertion, the free end side of the band portion protruding from the binding hole of the sheet is Make sure it is in a retaining state. Means for setting the retaining state is not limited at all.

[0013] Thus, the small number of sheets are bound by the binding band before cutting. In the case of binding a stacked body composed of a large number of paper sheets, the length of the band-shaped portion protruding from the binding hole of the paper sheet is reduced by the increase in the thickness of the stacked body. When the binding band is left as it is, it is difficult to maintain the binding band after the paper band is inserted.

Therefore, in this case, the connecting piece is cut to divide the binding band into two binding band halves, and the band portion of each binding band is inserted into the paper sheet. Pull in each direction. Then, since the binding band half is in a retaining state with respect to the paper sheet by the stopper portion, the binding band half projects from the binding hole without falling off from the binding hole. The length of the strip to be formed can be increased.

At this time, as in the second aspect of the present invention,
In the "the binding band is made of synthetic resin, the boundary between the band-shaped portion and the stopper portion is set to be thin".
The belt-shaped portion is easily bent with respect to the stopper portion. Therefore, when the band is bent at a right angle to the stopper, the connecting piece is cut, and when the band is pulled up in the insertion direction, the stopper is It is an aspect that is located parallel to the class.

Further, in this case, as in the third aspect of the invention, the stopper portion includes an extension piece extending from both ends of the boundary portion on both sides of the band portion along the band portion. In the configuration, when the band is bent at the boundary portion with respect to the stopper, the stopper having the pair of extension pieces surrounds the base end of the band. It is a mode that is located.

According to a fourth aspect of the present invention, in the configuration of the first to third aspects of the invention, "the sheet is bound by the binding band along one side of the cover,
The overall length of the binding band is set shorter than the length of the side of the cover. " Before cutting the connecting piece, each band-shaped portion of one binding band is inserted into the binding hole of the paper sheet, and after being protruded, bent in a direction away from each other to be in a retaining state. In the case of a binding device, when the sheets are not bound or when a very small number of sheets are bound, the pair of binding bands in the connected state is positioned substantially on a straight line. That is, in this state, the distance from one end of one band to one end of the other band substantially coincides with the entire length of the binding band.

Since the entire length is set to be shorter than the length of one side of the cover body where the sheets are bound, when the sheets are not bound or only a few sheets are bound, Both ends of the bound binding band do not protrude from the cover.

[0019]

As described above, according to the first aspect of the present invention, when a small number of sheets are bound, the length of the band-shaped portion projected from the binding hole is not changed. By not providing the band as long as necessary, the inconvenience that the free end of the band-shaped portion after being inserted into the paper sheet becomes an obstacle is eliminated.

In the case of binding a large number of sheets,
Since the length of the band-shaped portion protruding from the binding hole can be set long, even if the amount of sheets to be bound increases, the free end of the band-shaped portion after insertion into the binding hole is sufficient. In addition, the length is such that the retaining state can be maintained. As described above, the length of the band-shaped portion after being inserted into the binding hole of the paper sheet can be freely changed according to the amount of the paper sheet to be bound. .

According to a second aspect of the present invention, in addition to the effect of the first aspect, the band portion can be bent at a right angle to the stopper portion, so that the band portion extends to the boundary portion. , Can be inserted through the binding hole, and the strip can be used without waste. At this time,
Since the stopper portion is positioned parallel to the paper sheet, the stopper portion functioning as a stopper for the strip-shaped portion does not interfere.

According to the third aspect of the present invention, in addition to the effects of the second aspect, when the band is bent with respect to the stopper, the stopper is positioned at a right angle to the band. Since the base portion surrounds the base end of the band-shaped portion, the stopper function of the stopper portion is improved. According to a fourth aspect of the present invention, in addition to the effects of the first to third aspects of the present invention, when the binding band is configured to be provided on a cover, non-use or a small number of sheets are bound. Even in such a case, an effect is added that there is no inconvenience that the free end of the band portion protrudes from the cover body and becomes unsightly.

[0023]

Embodiments of the present invention will be described below with reference to the drawings. In the binding device according to the embodiment of the present invention, the width of the spine portion (11) can be changed in accordance with the amount of sheets (P) to be bound, having the same configuration as that shown in FIGS. The cover is made of a vertically long paper cover (1).

The width of the spine (11), which is continuous with one long side of the front cover (10), is set to be slightly shorter than that of the front cover (10). The back cover part (12), which is formed in the same shape and size as the part (10), has an inner plate (12b) inside the cover body (1) and an outer plate (12c) outside the cover body (1). ). These inner plate (12b) and outer plate (12

[0025] The inner plate (12b) has an extended portion formed by extending a predetermined length from the open end side of the storage portion (12a).
This extension is bent inward at right angles to the inner plate (12b) to form a first holding piece (15).
On the other hand, the front cover part (10) and the spine part (11) are folded over the boundary between the front cover part (11) and the front cover part (11).
(10) and the second holding piece (16) standing upright with respect to the spine part (11)
Are formed along the boundary line.

A locking projection (13) is formed on the surface of the second holding piece (16) on the side of the front cover (10) as in the prior art.
A resin reinforcing plate (17) is attached. The first sandwiching piece (15), the second sandwiching piece (16) and the reinforcing plate (17) have the same structure as those provided on the above-mentioned conventional cover body. The binding band (3) according to the embodiment of the present invention provided on the cover (1)
Is composed entirely of synthetic resin, as shown in FIG.
A pair of flexible strips (30) located at both ends, and a planar shape provided between the strips (30) and open to the strip (30) side is substantially U-shaped (or substantially C-shaped). ) Of a pair of stoppers
(31) and a thin connecting piece (33) connecting the stoppers (31) to each other.
The stopper portion (31) has a shape connected to the inner central side (31a) via a thin portion (34). This allows the strip
The base end of (30) is surrounded by a stopper portion (31) having extension pieces (311) and (311) on both sides, and has a thinner portion (34) with respect to the stopper portion (31). Bendable.

The entire length of the binding band (3) is
It should be set to approximately match or slightly shorter than the vertical length of (1). When a small number of sheets (P) are bound on the cover (1), as shown in FIG. 2, most of the spine (11) is stored in the housing (12a) of the back cover (12). ), The first holding piece (15) and the second holding piece (16) come close to each other.

In this case, the binding band (3) is used in a connected state as shown in FIG.
The through hole (15a) of the first holding piece (15) communicating with the
Filing holes of (P) (P _1), the through hole of the second clamping piece (16) (16a), together they are inserted sequentially into the through-hole of the reinforcing plate (17) (17a), provided in the reinforcement plate (17) L-shaped locking projection (13)
And bent into the locking projections (13) from the open side thereof and locked. As a result, a small number of paper sheets (P) are separated from the first holding piece (15) and the second holding piece (16).
Is bound by one binding band (3).

At this time, the reinforcing plate (1) of each strip (30)
7) By making the protruding length from
The connecting piece (33) is located substantially in the center area of (15).
When not in use or when binding only a few sheets (P), the first holding piece (15) and the second holding piece (16) come close enough to be in contact with each other. The band-shaped portion (3) located along the surface of the band (3) on the back cover (12) side of the first holding piece (15).
A part of (0) and a part of the band-shaped part (30) located along the reinforcing plate (17) are in an aspect that is located substantially on a straight line. Binding band
As described above, the overall length of (3) is substantially equal to or slightly shorter than the vertical length of the cover (1). Does not protrude from the upper and lower ends of the cover (1).

As the number of sheets (P) to be bound increases, the spine section (11) is pulled out from the storage section (12a) of the back cover section (12), and a stack of sheets (P) is stacked. The width of the spine part (11) is set according to the thickness of the back cover. Even in this case, the length of the band-like portion (30) protruding from the through hole (17a) of the reinforcing plate (17) is
As long as the length can be sufficiently locked to (13), the binding band (3) may be used as it is. However, the thickness of the laminate increases, the band-like portion (30) protruding from the through hole (17a) of the reinforcing plate (17) becomes short, and the free end of the band-like portion (30) engages with the locking projection (1).
When it becomes difficult to lock in step 3), forcibly disconnect the connecting piece (33). As a result, the binding band (3) is
A pair of binding band halves (3a) (3
divided into b).

When the band portion (30) of each binding band half (3a) (3b)) is pulled toward the reinforcing plate (17), the binding band half (3a) (3b)
As shown in (1), the stopper portion (31) can be pulled out until it comes into contact with the surface of the first holding piece (15) on the side of the back cover (12), and the strip portion (30) is thinned (34). And the stopper
Since it rises at a right angle to (31), the binding band half (3
a) and (3b) are fixed to the first holding piece (15) by the stopper portion (31) so as not to be pulled out.

By doing so, the length of the band-like portion (30) protruding from the reinforcing plate (17) is substantially the center of the first holding piece (15) where the thin portion (34) was located in the connected state. From the area, through holes (1
It is longer by a length corresponding to the distance (L) to 5a) (see FIG. 2) and can be projected from the first holding piece (15), and can be projected from the reinforcing plate (17) accordingly. The length of the band portion (30) also becomes longer. Therefore, even when a large number of paper sheets (P) are bound, the through holes (1
The band-shaped portion (30) projecting from 7a) can be set to a length sufficient to be locked by the locking projection (13).

Although the connecting piece (33) is formed so as to be cuttable, the connecting piece (33) should be strong enough not to be cut carelessly during use of the binding band (3) before cutting. Unless it is forcibly cut, it is not divided into the binding band half bodies (3a) and (3b). In this embodiment, the connecting piece (33) is formed to be thin to facilitate cutting.However, the pair of stoppers (31) are integrally formed, and the connecting piece (33) is formed.
Cutting may be performed by providing a perforation or the like at a position corresponding to (33).

Further, the shape of the binding band (3) is not limited to the one shown in FIG. 1, but may be a pair of band portions (30) and bendable with respect to the band portions (30). A pair of stopper portions (31) that can fix the portion (30) in a retaining state, and a stopper portion.
