Technical field

TECHNICAL FIELD [0001] The present invention relates to a binder for binding documents and the like, and more particularly to a binder capable of expanding the width of a back cover of a cover member.

Background art

Conventionally, a binder for binding a file object such as a document has a cover member and a binding mechanism for binding the file object inside the cover member. Generally, a cover member is a cover member. It has a back cover and a back cover. In general, a noinder has two holes formed on a file object such as a document, and two holes or a flexible band member. There is a clamp type binder that presses and clamps the left end of the file object without forming it.

[0003] In a conventional general two-hole binder, the position of the file object relative to the binder is determined, so the file object must be supported in a state of floating from the bookshelf shelf or the top of the desk. Therefore, a highly rigid cover member is used, the width of the spine cover is constant, and the width of the spine cover cannot be increased as the thickness of the file object increases.

In the two-hole type noinder of Patent Document 1, the center of the spine cover is configured so that the width of the spine cover can be expanded as the thickness of the file object increases, with the two rods configured to be extendable. It is divided, and the connecting pieces on both sides of the divided part are connected by two sets of X links.

[0004] In the conventional general clamp system binder, the width of the back cover of the cover member is constant and is not configured to be able to expand the width. However, the binder of Patent Document 2 proposed by the inventor of the present application is based on a base plate, a pair of links, a guide mechanism for movably guiding the lower ends of these links, and the lower ends of the pair of links in the phase approaching direction. It has a one-way lock mechanism that locks it so that it does not move, and a switching mechanism that switches this one-way lock mechanism to the unlocked state, allowing files from thin objects, file objects to thick objects, and file objects. This binder Then, the width of the back cover is expanded by changing the position of the broken line at the boundary between the front cover and the back cover.

[0005] On the other hand, in a two-hole binder, the spine is made of thin flexible paper, and the extension of the spine is inserted into the double cover. A special binder is also available that extends the spine cover width by extending the spine extension as the file object increases in thickness, creating a new fold line.

BEST MODE FOR CARRYING OUT THE INVENTION

Embodiments of the present invention will be described below with reference to the drawings. As shown in FIGS. 1 and 2, the binder 1 is used to file various file objects P such as documents. The binder 1 includes a front cover member 2 having a front cover 3, a back cover 4, and a spine cover 5 connecting them, a split connecting portion 6 provided on the cover member 2, and four sets included in the split connecting portion 6. Fastener 13 (see Fig. 7), binding mechanism 7 for binding the file object P between the front cover 3 and the back cover 4, and the cover member 2 are separate members and the back cover. At least one or more spine cover enlargement members 8 capable of expanding the width of the back cover, and for example, 12 sets of fasteners 13 provided incidentally to the spine cover enlargement member 8 are provided. Hereinafter, the binder 1 in a horizontal position for attaching and detaching the file object will be described as an example.

[0016] The binding mechanism 7 is a clamp-type binding mechanism that performs binding in a state where the left end portion of the file object P is pressed with the force of a hand. Therefore, the position of the file object P relative to the cover member 2 of the binder 1 can be freely set in the clamp release state. The size of the front cover 3 and the back cover 4 of the binder 1 in this embodiment is set to be equal to or slightly larger than, for example, the A4 size, and the front end of the file object P (the lower end in the state where the binder 1 is erected) is set. An example of the cover member 2 in the case where the file is filed in a state of being substantially aligned with the front end of the cover member 2 is shown (see FIG. 2).

[0017] Even when the thickness of the file object P increases, the weight of the file object P hardly acts on the cover member 2, and therefore, a relatively thin sheet material (for example, a normal binder) that is not very rigid. The cover member 2 is composed of, for example, a cardboard or a synthetic resin sheet material having a thickness of about 1.0 to 1.5 mm. However, when the total weight of the file object P is supported by the cover member 2, a highly rigid cover member having a thickness of about 1.5 to 2.0 mm is used, and the sizes of the front cover 3 and the back cover 4 are set to the size of the file object. It may be formed somewhat larger than the size.

[0018] FIG. 1 shows the binder 1 in the initial state in which the file object P has a small thickness, and FIG. The binder 1 A is shown in an enlarged view. As shown in Fig. 1, the spine cover 5 is connected to the left end of the front cover 3 of the cover member 2 with the fold line 3a as a boundary, and at least one end in the width direction of the spine cover 5 is connected to the back cover 4. A split connecting portion 6 is formed to be separably connected. For binder 1 used in normal applications, the width of the spine 5 in the thickness direction of the binder 1 and the enlargement of the spine The width of the member 8 is desirably 20 to 30 mm, for example, but is not limited to this range. The binder 1A shows a state in which the width of the spine cover is enlarged by adding one spine enlargement member 8, but two or more spine enlargement members 8 can be added.

Next, the divided connection part 6 will be described.

As shown in Fig. 1 and Fig. 8, the end of the back cover 5 on the back cover side (one end in the width direction of the back cover) also has a flange part that is bent at right angles to the inside of the back cover 4. A connecting portion 10 is formed. The first connecting portion 10 has, for example, four circular holes 12a, and four circular holes 12a for mounting the fastener tool 13 are formed.

[0020] At the left end of the back cover 4 on the back cover side, a second connecting portion 11 (see FIG. 8) is formed, which is a flange corresponding portion force to which the first connecting portion 10 is detachably connected. The two connecting portions 11 are formed with four circular holes 12b corresponding to the four circular holes 12a of the first connecting portion 10. The first and second connecting portions 10 and 11 are formed by inserting the shaft portion 14b of the fastener tool 13 into the four sets of circular holes 12a and 12b and attaching the retaining ring member 15 to the annular groove 14c of the shaft portion 14b. They are separably connected (see Figures 7 and 8). In this way, the dividing connecting portion 6 is formed in the first connecting portion 10 formed at the end portion of the back cover 5 and the first connecting portion 10 formed at the end portion of the back cover 4 so as to be separably connected to the first connecting portion 10. 2 connecting parts 11.

Next, an example of the fastener tool 13 will be described.

As shown in FIG. 7, the fastener tool 13 includes a fastener member 14 made of metal or synthetic resin, and a retaining ring member 15 made of metal or synthetic resin. The fastener member 14 has a disk-shaped head portion 14a, a shaft portion 14b that extends from the head portion 14a and can be inserted into the circular holes 12a to 12d, and an annular groove 14c formed in the shaft portion 14b. The distance from the head 14a to the lower end of the annular groove 14c is equal to the total thickness of the superimposed first and second connecting portions 10 and 11.

[0022] The retaining ring member 15 includes a pair of guide pieces 15a and 15b, an engagement hole 15c that engages with the inner peripheral surface of the annular groove 14c through slight elastic deformation of the guide pieces 15a and 15b, It has a guide slot 15d connected to the engagement hole 15c, and an operating portion 15e for operating with a finger. FIG. 8 is a cross-sectional view showing a state in which the first and second connecting portions 10 and 11 are fixed in close contact with the fastener tool 13. The first and second connecting portions 10 and 11 include, for example, four sets of fastener tools 13. It is connected by.

Next, the spine enlargement member 8 will be described. As shown in Fig. 1, the back cover portion of the back cover expanding member 8 is approximately the same width as the back cover 5, and the back cover expanding member 8 is made of the same cardboard or synthetic resin sheet material as the cover member 2. ing. At one end of the spine cover enlargement member 8 on the front cover side, a third connection part 16 is formed which is the same as the first connection part 10 and includes a flange part bent at a right angle to the inside. The third connecting part 16 is formed with four circular holes 12c corresponding to the four circular holes 12a of the first connecting part 10.

[0024] The other end of the back cover expanding member 8 on the back cover side is a fourth connecting portion 17 similar to the first connecting portion 10, and includes a flange portion bent at a right angle to the inside. A portion 17 is formed, and four circular holes 12d corresponding to the four circular holes 12b of the second connecting portion 11 are formed in the fourth connecting portion 17.

[0025] When the width of the spine cover is increased in order to increase the number of file objects P filed in the binder 1 shown in FIG. 1, the retaining ring members 15 of the four sets of fasteners 13 at the dividing connection portion 6 are removed. In this state, the first connecting part 10 is separated from the second connecting part 11, and the back cover expanding member 8 is arranged between the first and second connecting parts 10 and 11, and the first and third connecting parts 10 and 16 are arranged. Are connected in a separable manner with four sets of fasteners 13, and the second and fourth connecting parts 11, 17 are separably connected with four sets of fasteners 13. As a result, the binder 1A shown in FIG. 2 is obtained.

Next, the binding mechanism 7 will be described.

As shown in FIGS. 2 to 6, the binding mechanism 7 is provided at a portion near the left end of the inner surface of the back cover 4. The binding mechanism 7 includes a base plate 20 made of a metal plate having a thickness of about 0.6 to 1.0 mm and fixed to the back cover 4 with, for example, four rivets 20a, and a pair of vertical orientations. Column 21, a pair of pressing tools 22 and an operation knob 23.

[0027] The column 21 stands vertically from the base plate 20, and this column 21 is formed by detachably connecting a plurality of the same column pieces 24. A number of column pieces 24 that are suitable for the thickness of the file object P are connected and used, and a plurality of unused column pieces 24 are used in the storage portion (not shown) on the inner surface side of the cover member 2. Accommodated with multiple fasteners 13 and spine enlargement 8.

[0028] As shown in FIGS. 9 to 12, the column piece 24 is a molded product made of metal or synthetic resin. For example, it is desirable to use an injection molded product of a magnesium alloy. The column piece 24 includes a piece body portion 25 having a substantially square horizontal section, a tapered leg portion 26 having a circular shape in the horizontal section and slightly smaller in diameter when directed downward, and a connecting hole 27 formed in the piece body portion 25. And an engagement surface 28 formed on the side surface of the piece main body 25 on the pressing plate 30 side. A pair of protrusions 26 a are formed at the lower end of the taper leg 26. The connecting hole 27 is formed as a tapered hole into which the tapered leg portion 26 can be inserted in a sealed manner.

[0029] The connection hole 27 has a pair of grooves 27a for introducing a pair of protrusions 26a. The pair of protrusions 28 are at positions that are 45 degrees out of phase in the clockwise direction in plan view with respect to the pair of grooves 27a. A bottom end force of each groove 27a is formed with an arc groove 27b that can turn the protrusion 26a in the horizontal direction by 45 degrees clockwise in plan view. Note that the arc groove 27b may be opened to the outside due to the restriction of the structure of the molding die for molding the column piece 24.

[0030] As shown in FIG. 12, the column piece 24 to be added is approached from above the column piece 24, and the tapered leg portion 26 is inserted into the connecting hole 27 of the lower column piece 24. Are rotated 45 degrees clockwise so that the pair of protrusions 26a are brought into close contact with the back of the pair of circular grooves 27b, and the lower surface of the piece body 25 of the column piece to be added is The lower column piece 24 is in close contact with the upper end surface of the column piece 24 so that the additional column piece 24 can be connected to the lower column piece 24 in a separable manner without rattling.

[0031] The length of the column piece 24 is preferably an appropriate value in the range of 10 to 30 mm, for example, but is not limited to this range. In the case of a metal column piece 24, the dimension of one side indicating the thickness of the piece main body 25 is, for example, 6 to: In the case of a synthetic resin column piece where LOmm is desired, the dimension of the one side is 8 to It is desirable to make it about 15 mm. However, the thickness of the column piece 24 is not limited to the above value.

However, the lowermost column piece 24L fixed to the base plate 20 does not have the taper leg portion 26, and is fixed to the base plate 20 by spot welding or the like. Alternatively, a short screw shaft portion instead of the tapered leg portion 26 is formed in the lowermost column piece 24L, and the screw shaft portion is formed in the base plate 20 (or a base plate portion reinforced with a reinforcing plate). The base plate 24L at the lowest position can be fixed by screwing it onto the other base plate 20 The cut and raised pieces formed in the above may be used for fixing with screws or pins.

As shown in FIGS. 13 and 14, the engagement surface 28 of the column piece 24 is a triangular wave surface with a pitch and a peak height force of about 1.5 mm, for example, and has a sawtooth shape with a vertical cross-sectional shape. Formed on the surface.

As shown in FIGS. 2 to 4, 13, and 14, the pressing tool 22 includes only a pressing plate 30 that presses the upper surface of the file object P, and the vertical movement of the pressing tool 22 relative to the column 21. As will be allowed, the column 21 has a cylindrical portion 32 formed with a guide hole 31 in a standing direction that can be smoothly inserted without rattling. The lower surface of the pressing plate 30 is a horizontal plane, and the upper surface is formed as an inclined surface, for example. Note that the lower surface of the pressing plate 30 may be formed at a position several mm lower than the lower end of the cylindrical portion 32 so that the thin file object P can be filed with certainty. As shown in FIGS. 13 and 14, an engagement surface 33 with which the engagement surface 28 of the column piece 24 is engaged is formed on the side surface on the pressing plate 30 side of the inner surface of the guide hole 31. The engagement surface 33 is formed in a triangular wave surface opposite to the engagement surface 28. The engaging surfaces 28 and 33 are formed in such a shape that the engaging surface 33 is driven downward as the engaging surface 28 approaches the engaging surface 33.

[0034] The screw shaft portion 23a of the operation knob 23 is screwed into the horizontal screw hole 34 of the left wall portion of the cylindrical portion 32 so that the column 21 can be pressed toward the pressing plate 30 at the tip of the screw shaft portion 23a. It is composed. When changing the height position of the pressing tool 22, loosen the operation knob 23, adjust the height position of the pressing tool 22, and then turn the operation knob 23 to the fastening side to engage the engagement surface of the column 21. 28 is engaged with the engagement surface 33 on the inner surface of the guide hole 31. When the control knob 23 is loosened or fastened, the forward and backward movement of the screw shaft 23a is about 2.0 mm, so the control knob 23 can be easily operated.

[0035] When the file object P is filed or taken out, loosen the operation knob 23, detach the file object, and press the pressing tool 22 downward with the right hand to press the file object P. In this state, turn the control knob 23 with the left hand and tighten it. As a result, the engagement surfaces 28 and 33 squeeze each other and the pressing tool 22 is locked so that it cannot move in the vertical direction. Therefore, the file object P is maintained in the pressing state, and the pressing state does not loosen. . When the engagement surfaces 28 and 33 are engaged by the operation knob 23, the engagement surface 33 is slightly driven downward by the engagement surface 28, so that the pressing force is strengthened compared to the manual pressing state. As shown in FIG. 13, a soft rubber plate 30a (for example, a thickness of 3 to 6 mm) is fixed to the lower surface of the pressing plate 30, and the file object P is pressed through the rubber plate 30a. Alternatively, a soft rubber band may be externally attached to the pressing plate 30. However, the engagement surfaces 28 and 33 are not limited to the above-mentioned ones, which may be flat friction surfaces having a large friction coefficient.

15 to 17 are cross-sectional views of the main part of the cover member 2 of the binder 1, 1 A, and only the short axis 13a is shown instead of the fastener 13 being shown. The same applies to FIGS. 18 to 29. 15 shows the main part of the cover member 2 of the binder 1 in FIG. 1, FIG. 16 shows the main part of the cover member 2 of the binder 1A in FIG. 2, and FIG. 17 adds two back cover enlargement members 8 The main part of the cover member of the binder 1B is shown.

[0037] Next, the action and effect of the binder 1, 1A will be described.

When the file object P is thin, it is used as the binder 1 as shown in Fig. 1. When the thickness of the file object P is increased, the back cover 5 as shown in binder 1A in Fig. 2 The spine cover expansion member 8 is added to expand the width of the spine cover 5 and the column piece 24 can be added to the column 21 of the binding mechanism 7 so that it can be used with the column 21 lengthened. Since it can be filed with a single binder from a file object to a thick file object, it is highly versatile and convenient for carrying around the binder.

[0038] With the spine cover enlarging member 8 assembled, the spine cover portion (spine cover region) of the front cover member 2 can be maintained flat. Further, even if the spine cover area of the cover member 2 is enlarged, the front cover 3 and the back cover 4 are not changed, so that the function of the cover member 2 can be ensured. The structure of the back cover portion (back cover area) of the cover member 2 is not complicated, and the cover member 2 can be made of cardboard or synthetic resin sheet material, so that the production cost is not so high.

[0039] When removing the file object that has been filed and creating a new file object, the back cover enlargement member 8 is removed to reduce the width of the binder back cover (back cover area). The binder can be used repeatedly.

Since the first, third, fourth connecting portions 10, 16, and 17 are formed of flange portions bent at right angles to the inside, it is possible to connect the connecting portions inside the cover member 2. Can Therefore, the appearance of the binder 1, 1 A is not deteriorated. Since the connecting portion is connected by the fastener tool 13 having a simple structure, connection and separation can be easily performed.

[0040] Since the clamp type binding mechanism 7 is provided, the file object P can be filed without forming two holes, which is convenient, a desired document in the file object P can be taken out, and the file Can also be done easily. In the case of a file object P having a large thickness, it can be strongly clamped and filed by pressing the pressing tool 22 by hand and fastening the file object P in a compressed state. .

[0041] Since the engaging surface 33 is driven downward by the engaging surface 28 when the operation knob 23 is fastened, the pressing force for pressing the file object can be increased. In the nodding mechanism 7, the operation knob 23 is operated to the fastening side so that the engagement surface 28 of the column piece 24 is engaged with the engagement surface 33 of the inner surface of the guide hole 31 so as to be locked.
