Description

  The present invention relates to a file including a binding tool that can adjust the maximum binding amount of paper sheets.

  Various files are known in which paper sheets such as documents and paper pieces are bound by a binding tool. In the conventional file, there is a problem that it is difficult to spread the file when paper sheets are densely bound in the binding tool. Moreover, when the dimension between the binding tools is widened in order to improve this, there is a problem that the spine must be widened.

As a technology developed to solve the above problems, a front cover part and a back cover part that are relatively movable, a back cover side spine width adjustment part and a back cover side spine width adjustment part that can adjust the spine width, A binding tool capable of changing the size that can be bound in accordance with the movement change, a lock unit that prohibits movement of the front cover part and the back cover part, and an operation unit that can operate the lock unit to a locked state or an unlocked state. A file is disclosed (see Patent Document 1). According to the technique described in Patent Literature 1, the front cover portion and the back cover portion can be moved in a direction in which the binding possible size of the binding tool is increased. Accordingly, even when there are many paper sheets to be bound, it is possible to widen the paper sheets suitably by widening the binding size of the binding tool.
JP 2005-132065 A

However, in the file described in Patent Document 1, the front cover portion and the back cover portion are configured as separate parts, and as a configuration for adjusting the spine width, the front cover side width on each of the front cover and the back cover. An adjustment part and a back cover side back width adjustment part are provided, and furthermore, a lock means for preventing the front cover and the back cover from being disassembled and an operation means for operating the lock means are only essential components. In addition, the structure of each component is complicated compared to other conventional files.
Further, in the technique described in Patent Document 1, since the back cover is overlapped in two layers, more material for the cover body is required than the back cover file having a single layer structure (single sheet structure). Since each component is more complicated than other conventional files, the number of parts increases and the material increases.
The file described in Patent Document 1 is naturally thicker than a general file composed of one (one-sheet) spine cover, and has the same strength as other conventional files. In order to realize the thinness of the spine, it is necessary to select a special material different from the conventional one.

  Such a problem is not limited to the file described in Patent Document 1, but a file that can change the maximum binding amount of the binding tool (the thickness of all the sheets to be bound) (hereinafter, “binding amount adjustable file”). The above problem has been pointed out more or less, and the price is higher than that of a general file whose maximum binding amount cannot be changed (hereinafter simply referred to as “general file”). It has become. For this reason, the file size adjustable file has an overwhelmingly small market scale despite its functional superiority compared to a general file.

  Further, the conventional binding amount adjustable file such as the file described in Patent Document 1 has a problem that the operation of changing the maximum binding amount of the binding tool is troublesome.

The present invention has been made in view of the above problems, and is a file having a binding tool capable of adjusting the binding amount, and provides a technique relating to a file capable of adjusting the binding amount with a simpler configuration than conventional ones. Let it be an issue.

  In the file according to the present invention, the base (substrate part) of the binding tool is divided into at least two parts in the spine width direction (including the first substrate part and the second substrate part), and the first substrate part and the second substrate part are respectively A first skewer and a second skewer are provided. The first skewer portion and the second skewer portion are respectively penetrated into the skewer portions by a binding hole by being brought into contact with, engaged with, or engaged with the other skewer portion on the open end side. Paper sheets are prevented from falling out of the binding tool (skewer). Various methods can be adopted for the method of engaging the first skewer and the second skewer. For example, one is a skewer and the other is a pipe, and the skewer is inserted into the hollow part of the pipe. This is a binding that does not drop out the bound documents even when the base end of each skewer part (the side opposite to the open end) is separated, such as by adopting a so-called pipe mechanism. A skewer (first skewer and second skewer) having a function of changing the amount is employed.

  At least one of the first base portion and the second base portion is a movable substrate portion that can move relative to the spine in the spine width direction. That is, the movable substrate part is movable relative to the other substrate part. A substrate portion that is not a movable substrate portion is fixed so as not to move relative to the spine. The mechanism by which the movable substrate part can be relatively moved is as follows.

  The movable substrate portion is provided with a through portion, and the back cover is also provided with a hole at a position corresponding to the through portion. In the state where the movable substrate portion and the back cover are overlapped, the fixing device engages with the peripheral portion of the through portion of the movable substrate portion and the peripheral portion of the hole portion of the spine cover, so that the movable substrate portion does not separate from the spine. It is a fixing tool. As such a fixture, various configurations can be adopted. For example, the following configurations can also be adopted.

(A) The fixing device includes an insertion part having a neck part that can penetrate the penetration part and a head part that cannot penetrate, and an engagement part is provided on the tip side (opposite side of the head part) of the neck part, The part is a through hole. In this configuration, the insertion portion of the fixing device is inserted from the engagement portion side into the penetration portion, and further inserted into the hole portion, and is engaged with the side surface (front side / outside) opposite to the surface in contact with the movable substrate portion on the spine cover side. Position the joint. Then, by engaging the engaging portion with the front side of the spine (that is, the peripheral portion of the hole) and fixing the insertion portion so that the relative position in the longitudinal direction of the spine with respect to the movable substrate portion does not move, The movable substrate portion is sandwiched between the engaging portion and the head, and the state where the movable substrate portion is not separated from the spine is kept (fixed).

(B) In the configuration of (a) above, a recess communicating with a space provided between the front side and the inside of the spine, that is, a configuration in which the recess and the space are holes. In this configuration, when the engaging portion side of the insertion portion is passed through the penetrating portion and then entered into the concave portion, and the engaging portion is engaged with the space portion, the fixing device is long in the spine with respect to the movable substrate portion. It is fixed so that it does not move relative to the direction. As a result, the spine and the movable substrate are sandwiched between the engaging portion and the head, and the movable substrate is kept (fixed) from being separated from the spine.

Other,
-A structure in which the fixing device penetrates the hole from the front side of the spine, and the head engages with the peripheral part of the through part in the movable substrate part,
A configuration in which the backing member is arranged near the hole on the front side of the back cover, and the penetration portion and the head of the fixing device penetrating the hole are engaged with the backing member (the best mode for carrying out the following invention) Configuration described in the form column)
Can also be adopted.

  In this file, the width in the back width direction of the insertion part of the penetration part and the hole part in the fixing device is a width that can be inserted into the penetration part and the hole part, and one of the penetration part and the hole part is more than the other. Is narrow in the width direction. That is, in the insertion portion of the fixing device, relative movement in the longitudinal direction of the spine is restricted and relative movement in the spine width direction is allowed within at least one of the through portion and the hole portion.

Therefore, the fixing device can move relative to at least one of the back cover and the movable substrate portion within a predetermined range in the back width direction in a state where the movable substrate portion is not separated from the back cover. Therefore, the movable substrate portion can move relative to the spine in the back width direction (relative movement on the spine in a direction approaching or moving away from the other substrate portion).
In addition, when the movable substrate part moves relatively as described above, the binding mechanism is a pipe type as described above in order to keep the sheet binding mechanism (binding mechanism) in a state in which the sheets are bound. A mechanism or the like is preferably employed.

  Further, the widths of the penetrating part and the hole part may not be set as described above, and the widths of both may be substantially the same. In this case, if the width of the part arranged in the penetration part of the fixing device (insertion part) is made narrower than the width of the penetration part, and the width of the part arranged in the hole part is made narrower than the width of the hole part, Equivalent action is obtained.

By providing at least one of the penetrating part and the hole part in the back width direction and selecting the penetrating part and the hole part through which the fixing device (insertion part) is inserted, the relative position of the movable substrate part to the other substrate part May be defined. Even in this case, it is possible to change the distance between the movable substrate portion and the other substrate portion only by selecting the through portion and the hole portion used for fixing, and further, the distance can be changed from the above configuration. Can also be kept fixed.
Even in this configuration, if the width of each through portion and the width of the hole portion are configured as described above, even in a state where the movable substrate portion is kept away from the back cover by the fixing device. The relative distance in the spine width direction between the movable substrate portion and another substrate portion can be changed.

  In the file configured as described above, the back cover and the front cover and / or the back cover may be connected by a plurality of hinges. That is, if a hinge that is adopted (bent) is selected according to the relative position (relative distance) between the two substrate portions, the spine width can be minimized according to the bound document. In addition, since the file structure is extremely simple compared to the prior art, not only can the work of changing the maximum binding amount be facilitated, but also the possibility of problems such as failures can be reduced. .

  ADVANTAGE OF THE INVENTION According to this invention, it is a file which has a binding tool which can adjust a binding amount, Comprising: The technique regarding the file which can adjust a binding amount with a simpler structure than before can be provided.

Next, an embodiment of a file according to the present invention will be described with reference to the drawings.
<Configuration>
FIG. 1 shows a perspective view of the file 100 in an unexpanded state. FIG. 2 is a perspective view of the file 100 in an expanded state. FIG. 3 shows the first binding portion 24 as the first skewer portion and the first binding portion 24 that actually binds the paper sheets from the binding tool 2 in FIG. 2 (so as to be inserted into the binding holes of the paper sheets and not to fall off). The state which removed the 2nd binding part 34 as a double skewer part is shown. FIG. 4 is an exploded perspective view of still another component of the file 100 shown in FIG. FIG. 5 is a perspective view showing the fixing device 4 in an enlarged manner as compared with FIG.

The file 100 includes a cover body 1, a binding tool 2, and a fixing device 4.
The file 100 can adjust the distance between the first substrate portion 21 and the second substrate portion 31 constituting the binding tool 2 according to the binding amount, that is, the binding width of the binding tool 2 can be adjusted (maximum). The binding amount can be changed.) Further, the cover body 1 is provided with an outer thin hinge 112 and an inner thin hinge 111, and the spine width of the spine cover 11 constituting the cover body 1 can be adjusted according to the closing width of the binding tool 2. Is possible. In the description of the present embodiment, the non-expanded state means a state where the distance between the first substrate portion 21 and the second substrate portion 31 is the narrowest as shown in FIG. In addition, the expanded state indicates a state in which the distance between the first substrate unit 21 and the second substrate unit 31 is expanded. Hereinafter, each configuration will be described in more detail.

[Cover body]
The cover body 1 includes a spine cover 11, a front cover 12 connected to one end in the spine width direction of the spine cover 11, and a back cover 13 connected to the other end in the spine width direction of the spine cover 11. Has been. In the present specification, the “back width” is a length obtained by connecting the front cover 12 and the back cover 13 with the shortest distance, and the “back width direction” is the extending direction of the straight line. In addition, a direction orthogonal to the spine width direction in the spine cover 11 is referred to as “the longitudinal direction of the spine cover” for convenience.
The cover body 1 can be composed of an existing material. For example, a cover member such as polypropylene is attached to the surface of the core material with an adhesive or the like, and a back cover member made of paper is attached to the back surface of the core material. Can be configured. In the present embodiment, the spine cover 11 and the front cover 12 and the back cover 13 connected to both ends of the spine cover 11 in the spine width direction are connected via the inner thin hinge 111 and the outer thin hinge 112, and the cover body. 1 is integrally formed (one-sheet configuration).

  In the spine cover 11, the spine cover side through hole 113 (hole) through which the shaft portion 42 (see FIG. 5) of the fixing device 4 for fixing the first substrate portion 21 and the second substrate portion 31 of the binding tool 2 penetrates. Is provided. The back cover side through holes 113 are provided as two through holes on the front cover 12 side as the through holes for attaching the first substrate part 21 and two on the back cover 13 side as the through holes for attaching the second substrate part 31. The total four spine side through-holes 113 are provided at predetermined intervals in the longitudinal direction of the spine cover 11. The predetermined interval is set as an interval for stably attaching the first substrate portion 21 or the second substrate portion 31 to the spine cover 11, and the binding amount changing function by the first binding portion 24 and the second binding portion 34. Is set in consideration of In the present embodiment, a so-called pipe-type mechanism is employed in which the binding rod 25 as the skewer-like portion is fitted into the pipe portion 35 as the pipe-like portion so as to bind the paper sheets. The predetermined interval is set in consideration of the range. In the present embodiment, each of the first substrate portion 21 and the second substrate portion 31 is configured as a movable substrate portion that can move relative to the spine cover 11 in the spine width direction. The device 4 is assembled to the spine 11 so as not to move away from the spine 11 and to move relative to the spine in the longitudinal direction.

  The back cover side through hole 113 is substantially rectangular in plan view. The vertical dimension of the spine cover side through-hole 113 (longitudinal direction of the spine cover 11) is substantially the same as the vertical length of the cross section of the shaft portion 42 of the fixing device 4, and the horizontal direction of the spine cover side through hole 113. The dimension in the back width direction of the back cover 11 is designed to be larger than the distance between the inner standing piece 45a and the outer standing piece 45b. That is, the length in the vertical direction of the spine side through-hole 113 substantially coincides with the length in the vertical direction of the shaft portion of the fixing device 4, and the movement of the fixing device 4 in the vertical direction is restricted. On the other hand, the lateral length of the spine side through-hole 113 is formed larger than the interval between the inner standing piece 45a and the outer standing piece 45b of the fixing device 4 so that the fixing device 4 can move. The fixing device 4 inserted into the through hole 113 is only allowed to move in the spine width direction of the spine cover 11.

Near each of the spine side through-holes 113, there are provided an inner locking hole 114 positioned closer to the center in the spine width direction of the spine cover 11 and an outer locking hole 115 positioned outward in the spine width direction. ing. Further, the inner locking hole 114 and the outer locking hole 115 are provided on an imaginary line X axis extending in the spine width direction of the spine cover 11. The inner locking hole 114 is provided on the virtual line Y1 axis orthogonal to the virtual line X, and the outer locking hole 115 is orthogonal to the virtual line X and parallel to the virtual line Y1. Is provided. The inner locking hole 114 accommodates the locking protrusion 46 of the fixing device 4 in the non-expanded state, thereby restricting the movement of the binding tool 2 in the non-expanded state. On the other hand, the outer locking hole 115 accommodates the locking projection 46 of the fixing device 4 in the expanded state, thereby restricting the movement of the binding tool 2 in the expanded state. Thus, the inner locking hole 114, the outer locking hole 115, and the locking projection 46 function as position adjusting means for fixing the position in the spine width direction on the spine cover of the movable substrate portion at an arbitrary position.

  The cover body 1 is provided with an inner thin hinge 111 and an outer thin hinge 112 in parallel as the thin hinges at the end portions of the spine cover 11 in the spine width direction. The inner thin hinge 111 functions as a rotation axis of the cover 1 in the non-expanded state. The outer thin hinge 112 functions as a rotation shaft of the cover 1 in the expanded state. That is, in the present embodiment, the spine width of the spine cover 11 can be adjusted according to the closing width of the binding tool 2. In the present embodiment, two thin hinges are provided at each end, but the number of thin hinges is not particularly limited. Three or more thin hinges may be provided, for example, a bellows shape. As described above, among the front cover 12 and the back cover 13, the cover on the side where the movable substrate portion exists (both sides in the present embodiment) on the basis of the center line with respect to the spine width of the spine cover 11 is plural between the spine cover and the back cover. It is connected via a book hinge.

[Binding tool]
Next, the binding tool 2 will be described. The binding tool 2 has a first substrate portion 21 fixed to the inner side of the spine cover 11 by the fixing device 4 and an outer end portion (end portion on the cover cover 12 side) of the first substrate portion 21 via a first hinge 23. A first substrate 22 connected to the first side plate 22, a first binding portion 24 that can be attached to and detached from the first side plate 22, and a second substrate portion that is fixed to the inside of the spine 11 by the fixing device 4 in parallel with the first substrate portion 21. 31, a second side plate 32 connected to an outer end portion (end portion on the back cover 13 side) of the second substrate portion 31 via a second hinge 33, and a second binding portion 34 detachable from the second side plate 32. And is composed of. Each component of the binding tool 2 is made of a metal member.

  The first substrate portion 21 is configured by a plate having a rectangular shape in plan view, and two first substrate portion side through holes 211 (through portions) are formed at predetermined intervals in the longitudinal direction. The shaft part 42 of the fixing device 4, the inner upright piece 45 a, and the outer upright piece 45 b can be inserted into the first substrate part side through hole 211. The predetermined interval is the same as the predetermined interval of the spine side through hole 113 described above, and the position of the first substrate portion side through hole 211 corresponds to the position of the spine side through hole 113.

The first substrate portion side through-hole 211 has a rectangular shape, and the length in the longitudinal direction of the spine is substantially the same as the length in the longitudinal direction of the spine of the fixing device. The fixing device 4 inserted through the part side through hole 211 is restricted from relative movement in the longitudinal direction of the spine cover with respect to the first substrate part 21.
The length in the back width direction of the first substrate portion side through hole 211 is substantially the same as the interval between the inner standing piece 45a and the outer standing piece 45b of the fixing device 4. Thereby, when the shaft part 42, the inner standing piece 45a, and the outer standing piece 45b are inserted into the first substrate part side through-hole 211, the fixing device 4 is moved relative to the back width direction of the first substrate part 21. Limited (fixed). That is, the first restriction means for restricting the movement of the fixing device in the spine width direction with respect to the movable substrate portion is realized by setting these sizes.
As described above, the spine side through-hole 113 is formed to have a width larger than the interval between the inner upright piece 45a and the outer upright piece 45b to allow the fixing device 4 to move. 211 also has a horizontal width that is substantially the same as the distance between the inner upright piece 45a and the outer upright piece 45b. In other words, the lateral width of the first substrate portion side through hole 211 is formed to be smaller than the lateral width of the spine cover side through hole 113.

  The second substrate unit 31 also basically has the same functions and operational effects as the first substrate unit 21 described above. That is, the second substrate portion 31 is provided with a second substrate portion side through hole 311, and the shaft portion 42 of the fixing device 4 can be inserted.

A first binding portion 24 can be attached to and detached from the first side plate 22. The first binding portion 24 is configured by a plate-like first binding main body portion 231 connected to the first side plate 22 and two binding bars 25 raised from the first binding main body portion 231 at a substantially right angle. . On the other hand, a second binding portion 34 can be attached to and detached from the second side plate 32. The second binding portion 34 includes a plate-like second binding main body portion 331 connected to the second side plate 32 and two pipes 35 raised from the second substrate at a substantially right angle. A spelling rod 25 can be inserted into the pipe 35.
Such a so-called pipe-type mechanism is different from a mechanism in which the ends of both skewers are engaged with each other, and the two can be connected even if the relative distance between the ends of both is changed. That is, even if the relative distance between the first binding main body 231 and the second binding main body 331 changes, the binding rod 25 as the first skewer and the pipe 35 as the second skewer are fitted. And a function of changing the binding leg length (binding amount changing function). More specifically, since the pipe 35 is inserted into the binding hole of the paper sheet, the pipe 35 has an outer diameter smaller than that of the binding hole. Since the binding rod 25 is inserted into the pipe 35, the outer diameter is designed to be smaller than the inner diameter of the pipe 35. The length of the pipe 35 is designed so that the tip reaches the first binding body 231 of the first binding portion 24 in the non-expanded state. The spelling rod 25 is also designed to have almost the same length as the pipe 35. Thus, each skewer portion that has reached the other spelling main body portion is fitted into a not-shown recess or the like provided in the other spelling main body portion, so that the skewer portion tip side is stably maintained in the file 100. The

  The file 100 according to the present embodiment includes an auxiliary pipe 61 that compensates for the shortage of the pipe 35 in the expanded state. The auxiliary pipe 61 is made of synthetic resin and is designed in the same manner as the pipe 35 in both outer diameter and inner diameter. The length of the auxiliary pipe 61 is designed based on the distance from the tip of the pipe 35 in the expanded state to the first binding body 231 of the first binding portion 24. The pipe 35 of this embodiment has a taper formed at the tip. Therefore, one end of the auxiliary pipe 61 is designed according to this taper. The auxiliary pipe 61 is arranged and used on the tip side of the pipe 35 in the expanded state. As a result, the auxiliary pipe 61 engages with the pipe 35 at the taper portion, and engages with the first binding main body 231 (a concave portion thereof) at the other end, so that the tip of the pipe 35 may flutter. Further, it is possible to reduce the possibility that paper sheets may be caught between the tip end of the pipe 35 and the first binding main body portion 231 of the first binding portion 24.

  The auxiliary pipe 61 is not necessary in the non-expanded state. Therefore, in the present embodiment, the auxiliary pipe 61 can be accommodated in the auxiliary pipe accommodating portion 54 that accommodates the auxiliary pipe 61 provided in the fixing device 4. Thereby, the loss of the auxiliary pipe 61 in the non-expanded state can be prevented. In addition, optimal reinforcement can be performed according to the relative distance of the 1st binding main-body part 231 and the 2nd binding main-body part 331 by preparing the auxiliary pipe 61 from which length differs. That is, even if the auxiliary pipe 61 is used, the back width (maximum binding amount) of the file 100 can be prevented from becoming larger than necessary.

  The other components in the binding tool 2 (for example, the first hinge 23, the second hinge 33, the first side plate 22, the first binding body 212 of the first binding section 24, the second binding body 331, etc.) Known techniques can be used as appropriate.

[Fixed part]
Next, the fixing part will be described. As shown in FIG. 5, the fixing device 4 includes a base member 40,
The slide member 50 is configured so that the first substrate portion 21 and the second substrate portion 31 as the movable substrate portions are not separated from the spine cover 11, and the position of the spine cover in the longitudinal direction is defined, and the back width direction Secure to the slide. In the present embodiment, four fixing devices 4 are provided, but since all have the same configuration, only one fixing device 4 that fixes the first substrate unit 21 will be described in detail.

  The base member 40 is connected to the thin plate-like retaining portion (cover cover pressing portion) 41 disposed on the outer side of the spine cover 11 and the retaining portion 41 at a substantially right angle. And the shaft part (neck part) 42 which protrudes on the inner surface of the 1st board | substrate part 21 in the state which penetrated the 1st board | substrate part side through-hole 211 of the 1st board | substrate part 21, and the retaining part at the top part of the shaft part 42 41, a locking plate 43 connected substantially parallel to the locking plate 43, guide portions 44 provided at both ends in the width direction of the locking plate 43 and projecting toward the retaining portion 41, and the shaft portion 42 coming out on both sides in the lateral direction. It is comprised by the inner side standing piece 45a and the outer side standing piece 45b which stood up from the stop part 41 at substantially right angle.

  The retaining portion 41 presses the outside of the spine 11 when fixed. The locking plate 43 restricts the upward movement of the slide member 50 (the direction orthogonal to the inner surface of the spine cover 11) when fixed. The shaft portion 42 connects the retaining portion 41 corresponding to the cover pressing portion and the locking plate 43 to which the slide member 50 corresponding to the binding tool pressing portion is engaged.

  The inner standing piece 45 a and the outer standing piece 45 b have a function of protecting the shaft portion 42. That is, if the inner upright piece 45a and the outer upright piece 45b are not provided, the side surface of the shaft portion 42 is in direct contact with the lateral edge of the spine cover side through hole 113 directly. Therefore, there is a possibility that an excessive load is applied to the shaft portion 42 in some cases. However, in the present embodiment, the inner upright piece 45a or the outer upright piece 45b is in contact with the lateral edge portion of the spine side through hole 113, so that the load on the shaft portion 42 can be suppressed. In addition, the movement amount of the 1st board | substrate part 21 can be adjusted by adjusting the space | interval of the inner side standing piece 45a and the outer side standing piece 45b. That is, the movement amount of the first substrate portion 21 can be adjusted by the lateral width of the spine side through-hole 113, but can also be adjusted by the interval between the inner standing piece 45 and the outer standing piece 45. The amount of movement of the second substrate portion 31 can also be adjusted based on the distance between the inner standing piece 45a and the outer standing piece 45b.

  Further, the retaining portion 41 is provided with a retaining projection 46. The locking projection 46 engages (fits) with an inner locking hole 114 or an outer locking hole 115 provided in the spine 11. Therefore, the locking protrusion 46 may be designed according to the outer shape of the inner locking hole 114 and the outer locking hole 115. Note that the height of the locking projection 46 can be appropriately designed within a range not exceeding the thickness of the spine cover 11. In the present embodiment, the locking protrusion 46 has the inner locking hole 114 and the outer locking hole 115 without separating the fixing device 4 by making the height slightly protruding from the flat plate portion of the retaining portion 41. You can move between.

  The slide member 50 as a binding tool pressing portion is provided on the slide member main body 51, a guide groove 52 provided on one side in the longitudinal direction of the slide member main body 51, and the other in the longitudinal direction of the slide member main body 51. And a gripping portion 53. The slide member main body 51 presses the first substrate portion 21 when fixed. When the guide groove 52 is fixed, the guide portion 44 of the base member enters. Therefore, the guide groove 52 is designed corresponding to the cross-sectional shape of the guide portion 44. When the guide portion 44 enters the guide groove 52, the upward movement of the slide member 50 is restricted by the retaining portion 41.

The grip portion 53 includes a bottom surface portion 531 lower than the top surface of the slide member main body portion 51 and a wall portion 532 provided along the outer edge of the bottom surface portion 531. Further, the wall portion 532 at the end portion in the pulling direction when the slide member 50 is pulled out from the base member 40 among the wall portions 532 is designed as a central wall portion 535 having a higher wall height than the other portions. Has been. As a result, the fingertip is more easily caught.

  A part of the bottom surface portion 531 is wound in a U-shape, and on the back surface of the tongue piece 533 formed inside the U-shaped through portion (the back surface side at a position indicated by reference numeral 534 in FIG. 5), A fixing portion side locking projection that slightly protrudes on the back cover 13 side is provided. The fixing portion side locking protrusion 534 can be engaged with fixing portion locking holes 213 and 313 provided in the first substrate portion 21. When the slide member 50 is gradually moved in a state where the shaft portion 42 and the like of the fixing device 4 are passed through the back cover side through hole 113 and the first substrate portion side through hole 211, the fixing portion side locking protrusion 46 gets over the end of the first substrate portion 21 and is finally accommodated in the fixing portion locking hole 213. As a result, the movement of the slide member 50 in the entry direction (a direction orthogonal to the spine width direction of the spine cover 11) is restricted.

  As described above, the fixing device 4 according to the present embodiment is provided with the auxiliary pipe accommodating portion 54 that accommodates the auxiliary pipe 61. The auxiliary pipe housing portion 54 is provided using the grip portion 53. Specifically, the central wall 535 is provided with a notch 536 that is open at the top and curved outward in accordance with the outer shape of the auxiliary pipe 61. In the non-expanded state, the auxiliary pipe 61 is accommodated in the auxiliary pipe accommodating portion 54, whereby the auxiliary pipe 61 can be prevented from being lost. In addition, since the pipe 35 of the binding tool 2 is two, at least two auxiliary pipe accommodating parts 54 are needed. However, the auxiliary pipe accommodating portion 54 may be provided in all the slide members 50. When three or more auxiliary pipe accommodating portions 54 are provided, the auxiliary pipe accommodating portion may function as an auxiliary auxiliary pipe accommodating portion. Moreover, you may make it prepare the auxiliary pipe 61 from which length differs, and accommodate this.

<How to use>
Next, how to use the file 100 will be described with the operation of each component. In the following description, a case where the file 100 is shifted from the non-expanded state to the expanded state will be described as an example.

  When the binding amount is small, the file 100 is used in an unexpanded state (the state shown in FIG. 1). In the non-expanded state, the inner standing piece 45a of the base member 40 is in contact with the inner edge of the spine cover side through hole 113 in the spine width direction. Therefore, in the non-expanded state, the distance between the first substrate portion 21 and the second substrate portion 31 is the narrowest. Moreover, since the latching protrusion 46 is accommodated in the inner latching hole 114, the movement of the fixing device 4 in the spine width direction is restricted. That is, the non-expanded state is stably maintained.

  In order to increase the maximum binding amount of paper sheets, first, the cover body 1 is opened, and the first binding portion 24 and the second binding portion 34 connected to the first side plate 22 and the second side plate 32 are removed. Once the spelling rod 25 is pulled out from the pipe 35, the auxiliary pipe 61 is passed through the spelling rod 25 (FIG. 3 → FIG. 2).

  On the other hand, the first substrate portion 21 and the second substrate portion 31 are respectively slid to the outside in the back width direction. In the file 100, the height of the locking projection 46 of the base member 40 is designed to be low, so that the locking projection 46 can get over the inner locking hole 114, and the fixing device 4 can be disassembled without disassembling. The one substrate part 21 and the second substrate part 31 can be slid. In addition, the movement of the 1st board | substrate part 21 and the 2nd board | substrate part 31 should just hold | grip the 1st side board 22 and the 2nd side board 32, and may make it transfer to an outer side gradually, for example. When gradually shifting to the outside, the locking projection 46 accommodated in the inner locking hole 114 passes between the inner locking hole 114 and the outer locking hole 115, and finally, It is accommodated in the outer locking hole 115. As a result, the binding tool 2 is fixed in the expanded state (the state shown in FIG. 3). In the expanded state, the outer standing piece 45 of the base member 40 is in contact with the outer edge of the spine cover side through hole 113 in the spine width direction.

When the expansion of the first substrate portion 21 and the second substrate portion 31 is completed, the binding rod 25 is passed through the pipe 35 that is passed through the binding hole of the paper sheet, and the first binding portion 24 and the second binding portion 34 are respectively connected. It connects to the 1st side board 22 and the 2nd side board 32 (state shown in FIG. 2).

  In the expanded state, the file 100 has a wider distance between the first substrate unit 21 and the second substrate unit 31 than in the unexpanded state. In addition, an auxiliary pipe 61 is provided at the tip of the pipe 35, and the binding rod 25 is covered with a pipe-like portion over the entire area. Further, by expanding the binding tool 2, the first side plate 22 and the second side plate 32 protrude outward in the back width direction, and the outer thin hinge 112 functions as a rotation shaft of the cover 1. That is, when the maximum binding width of the binding tool 2 is expanded, the spine width of the spine cover 11 is expanded.

According to the file 100 described above, the maximum binding amount can be increased by sliding the first substrate portion 21 and the second substrate portion 31 outward in the back width direction. In the present embodiment, since the first substrate portion 21 and the second substrate portion 31 can slide about 5 mm each, the binding width can be expanded by about 10 mm.
The file 100 is composed of a small number of parts such as a cover body 1, a binding tool 2, and a fixing device 4. Furthermore, the structure is relatively simple and no complicated mechanism or the like is provided.
Further, the binding amount can be adjusted while the binding tool 2 is fixed to the cover body 1, the operation method is simple, and even a first-time user can easily handle it.

  Conventionally, when a file is used, the number of paper sheets to be accommodated increases, and there are many cases in which the user feels that he wants to increase the binding amount of paper sheets. That is, instead of preparing a new file and binding it again, there is a user's need to increase the binding amount slightly and bind the paper sheets together in one file. When it is desired to slightly increase the binding amount in this way, a file that can increase the binding amount with a simple configuration, in other words, a configuration close to the configuration of an existing file is required. On the other hand, the file 100 meets the above request without complicating the configuration or increasing the number of parts.

  The preferred embodiment of the present invention has been described above, but the present invention is not limited to this, and it is needless to say that various design changes can be made without departing from the technical idea of the present invention.

  For example, as shown in FIG. 6, the spine side through-hole 113 may be divided into a non-expanded state through-hole 113a and an expanded state through-hole 113b. In this case, when the transition from the non-expanded state to the expanded state, or the transition from the expanded state to the non-expanded state, it is necessary to separate the fixing device 4. However, each state can be maintained more firmly. Further, if the width in the back width direction of the through hole 113a and the through hole 113b is set wider than the distance between the inner upright piece 45a and the outer upright piece 45b, the same effect as the above embodiment (the maximum binding amount is slightly reduced). (Effects to meet the demand to increase). That is, a plurality of at least one of a binding tool side through hole that is a through portion and a spine side through hole that is a hole portion are provided, and the first substrate portion and the first through the through portion through which the fixing device penetrates and the engaging hole portion. You may comprise so that the relative distance in the spine width direction of two board | substrate parts may be determined.

If three or more locking holes corresponding to the locking protrusions 46 are provided, the maximum amount of binding stably maintained in the binding tool 2 can be increased, which contributes to optimization of the back width and the like.
In the file 100, both the first substrate unit 21 and the second substrate unit 31 are movable substrate units. However, at least one of the files 100 may be a movable substrate unit.
The fixing method by the fixing device 4 is not limited to the above, and any method (mechanism) may be used as long as the substrate portion of the binding tool that can withstand the mechanism is fixed to the cover 1.
The fixing device 4 may be configured by rivets having heads at both ends of the shaft portion 42. As a result, a file with a simpler configuration can be provided.

A guide mechanism for guiding the sliding movement between the non-expanded state and the expanded state may be provided. For example, as shown in FIG. 4 and the like, the guide claws 212 projecting to the back surface side (contact side with the spine cover 11) of the first substrate portion 21 at both edges in the longitudinal direction of the first substrate portion side through hole 211. , And the guide claw 212 can be engaged with the end portion of the spine side through-hole 113 to constitute a guide mechanism.
Of course, the following configuration may also be adopted.

  The file includes a back cover, a cover body having a front cover and a back cover respectively connected to both ends in the spine width direction of the spine cover, and a binding tool. The binding tool includes a first substrate portion and a second substrate portion that contact the spine, and a first skewer portion provided on the first substrate portion and a second skewer portion provided on the second substrate portion. Yes. At least one of the first substrate portion and the second substrate portion is a movable substrate portion that can move relative to the other substrate portion in the spine width direction, and the first skewer portion and the second skewer portion are Corresponding to the relative movement of the first substrate portion and the second substrate portion in the spine width direction, it has a binding amount changing function capable of binding paper sheets regardless of the distance between them. ing. The movable substrate portion includes a through portion, and a hole portion is provided at a position corresponding to the through portion in the spine. The fixing device penetrates the through portion, and the periphery of the hole portion in the spine and the through portion in the substrate portion. Engage with the periphery to keep the movable substrate part away from the spine. And the width | variety of the back width direction of a penetration part is narrower than the width | variety of a hole.

  This file preferably further includes first limiting means for limiting movement in the spine width direction with respect to the movable substrate portion of the fixing device. In addition to the configuration of the above-described embodiment, for example, a configuration in which the fixing device and the movable substrate unit are directly engaged can be adopted as the first limiting unit.

  In the above file, even if the width in the back width direction of the penetrating portion is made wider than the width of the hole portion, the same operation and effect are obtained. In this case, instead of the first limiting means, it is preferable to provide second limiting means for limiting the movement of the fixing device in the spine width direction with respect to the spine.

  The file is further preferably provided with position adjusting means for fixing the position in the spine width direction on the spine of the movable substrate portion at an arbitrary position.

  Further, in the above file, the width in the back width direction of the through portion and the width in the back width direction of the hole portion are substantially the same, and the width in the back width direction of the portion disposed in the through portion in the fixing device is Even if the width in the back width direction of the portion arranged in the hole portion in the fixing device is narrower than the width in the direction, the same effect and effect as described above can be obtained. Even in such a configuration, the limiting means and the position adjusting means are preferably provided.

  In the file as described above, the cover on the side where the movable substrate portion exists with respect to the center line with respect to the spine width direction of the back cover and the back cover, with a plurality of hinges between the back cover and the back cover. Configured to connect. As a result, the back width and the maximum binding amount can be changed even if the cover body is constituted by one sheet.

A cover body having a spine cover, a front cover and a back cover respectively connected to both ends in the spine width direction of the spine cover, and a binding tool for binding paper sheets, and attached to the spine cover of the cover body A first substrate portion, and a second substrate portion attached substantially parallel to the first substrate portion in the spine width direction of the spine cover, and the first substrate portion and the second substrate portion, At least one of the binding tool that is movable relative to the spine in the spine width direction of the spine cover, and at least one of the first substrate portion and the second substrate portion, the spine width of the spine cover A file having a fixing portion that is fixed to be movable in a direction. In this file, the binding amount can be adjusted by moving at least one of the first substrate portion and the second substrate portion constituting the binding tool in the spine width direction of the spine. Further, in a conventional file that adjusts the binding amount by relatively moving two stacked spine covers, a spine width adjustment unit is provided on each of the front cover and the back cover configured as separate parts. Therefore, a lock unit for preventing the front cover and the back cover from being disassembled and an operation unit for operating the lock unit are required. On the other hand, in this file, it is only necessary that the first substrate portion or the second substrate portion can move with respect to the back cover, and it is not necessary to move the cover body. Accordingly, the configuration of the spine can be simplified. Also, it is not necessary to have a configuration such as a lock unit for preventing the front cover and the back cover from being disassembled and an operation unit for operating the cover. That is, it is possible to provide a file in which the binding amount can be adjusted with a simpler configuration with a smaller number of parts than before. In addition, since the back cover of the cover body does not overlap, the thickness of the back cover can be made the same as that of a general file, and the material of the cover body is reduced compared to the conventional technology where the back cover overlaps. can do.

  In the above file, the substrate part constituting the binding tool is composed of two members (first substrate part and second substrate part), and the binding amount is adjusted by adjusting the distance between the two substrate parts. Can do. Since the first substrate portion and the second substrate portion are movably attached to the spine cover of the cover body by a fixing member, the first substrate portion and the second substrate portion can move at least within the spine width of the spine cover. Is possible.

  As described above, this file is characterized in that the state of the binding tool changes as the substrate portion of the binding tool moves. Therefore, in consideration of the state change of the binding tool, the binding tool may be configured as follows. That is, the binding tool has a non-expanded state in which the distance between the first substrate portion and the second substrate portion is the narrowest, and the distance between the first substrate portion and the second substrate portion is the spine width of the spine. And an expanded state that expands within.

  In the expanded state, the distance between the first substrate portion and the second substrate portion is wider than in the non-expanded state. Therefore, when designing this file, the first substrate portion and the second substrate portion may be designed to fit within the spine width of the spine cover in the expanded state. Note that the change from the non-expanded state to the expanded state, or the change from the expanded state to the non-expanded state may be performed by the user appropriately holding the first substrate portion or the second substrate portion. However, the change from the expanded state to the non-expanded state can use an external force applied via the front cover or the back cover. Specifically, when it can be used in the non-expanded state but is stored in the cupboard in the expanded state, it is sandwiched between other adjacent files and is naturally changed to the non-expanded state by applying force from the side. The Even if the amount of binding is large and it is impossible to change to the non-expanded state, if there is a margin for the amount of binding in the expanded state at the time when it is stored in the cupboard, it will match the binding amount by the force of the adjacent file. Changed to the expanded state.

  Here, in this file, at least one of the front cover and the back cover is a hinge serving as an opening and closing shaft when the cover body is opened and closed, and is provided at the end of the spine cover in the spine width direction. The back cover is connected to the spine through a plurality of hinges provided in a stepwise manner in the spine width direction, and the cover is switched from the plurality of hinges according to the binding amount from the plurality of hinges. The back width of the spine may be adjusted stepwise.

  According to this file, the back width of the spine can be adjusted by switching the hinge functioning as an opening / closing axis from among a plurality of hinges. The hinge can be, for example, a thin hinge. The number of hinges is not particularly limited, and the back width can be gradually expanded as the outer hinge is used. However, in this file, when the outer hinge is used, the extension of the spine width is realized by using the area that was originally the front cover or the back cover as the back cover. Therefore, when designing the number of hinges, it is preferable to consider the width of the front cover or the back cover.

The switching of the hinge is performed according to the binding amount, in other words, according to the interval between the first substrate portion and the second substrate portion. For example, when the binding amount is small, the inner hinge in the spine width direction functions, and when the binding amount is large, the outer hinge in the spine width direction functions. The hinge may be switched by the user. However, if the hinge is formed of a thin hinge, the hinge can be switched according to the binding amount without any change by the user.

  Moreover, this file is good also as a structure further provided with the control part which controls the movement of the board | substrate part fixed so that a movement is possible by the said fixing | fixed part among said 1st board | substrate part and said 2nd board | substrate part.

  By providing the restricting portion, the movement of the substrate portion can be restricted. In other words, the restriction unit can restrict the change from the non-expanded state to the expanded state and the change from the expanded state to the non-expanded state.

  Note that the binding tool in this file can be configured by a pipe-type binding tool that inserts a binding tube into a binding hole of a paper sheet. On the other hand, this file can adjust the amount of binding by adjusting the distance between the first substrate portion and the second substrate portion constituting the binding tool. Therefore, in the case of a pipe-type binding tool, it is preferable that the length of the pipe can be adjusted according to the distance between the substrate portions. In addition, for example, in the case where a binding rod is inserted into the pipe, it is assumed that the length of the pipe is insufficient due to the expansion of the binding tool. Since the spelling rod is contained in the pipe and the contained spelling rod is exposed by the expansion, the paper sheets do not fall off even when expanded. However, in the part where the pipe is insufficient, there is a concern that the paper sheet is held by a spelling rod having an outer diameter smaller than that of the pipe, and the spelling tube is rattled.

  Therefore, in order to solve such a problem, this file is a pipe in which the binding tool is detachably connected to the first substrate portion and the second substrate portion, and is inserted into a binding hole of a paper sheet. The binding tool further includes an unextended state in which the interval between the first substrate portion and the second substrate portion is the smallest, and the interval between the first substrate portion and the second substrate portion. It is good also as a structure which has the expansion state which expands within the spine width of the spine, and has an auxiliary pipe connected to the tip of the pipe in the expansion state.

  According to this file, it is possible to prevent rattling of the spell tube by providing the auxiliary pipe. Moreover, the change from the expanded state to the non-expanded state can be restricted by connecting the auxiliary pipe to the tip of the pipe.

  The auxiliary pipe is used only when the binding tool is in the expanded state. Therefore, in order to prevent the loss of the auxiliary pipe when not in use, for example, an auxiliary pipe accommodating portion that accommodates the auxiliary pipe may be provided in the fixing portion. Thereby, an auxiliary pipe can be accommodated in a non-expanded state, and loss of the auxiliary pipe can be prevented. Note that the auxiliary pipe housing portion is not limited to the fixed portion, and may be provided, for example, in a part of the cover body.

Here, this file described above may be more specific in each configuration and may be as follows. Specifically, the fixing portion includes a cover pressing portion that presses the spine, a binding tool pressing portion that presses at least the moving substrate portion of the first substrate portion and the second substrate portion, and the cover pressing portion. And a shaft portion to which the binding tool pressing portion is connected. Note that the cover pressing portion and the shaft portion may be configured integrally, and the binding tool pressing portion may be configured to be separable from the cover pressing portion and the shaft portion configured in this manner. By making the fixing portion separable as described above, the cover body and the binding tool can be easily separated. Note that the force that the cover holding part holds the back cover and the force that the binding tool holding part holds the moving board part is so that the board part can move when the fixing part sandwiches the cover body and the board part of the binding tool. You only have to set it. Specifically, it can be designed as appropriate by adjusting the length of the shaft portion.

  Moreover, the board | substrate part which moves at least among the said 1st board | substrate part and said 2nd board | substrate part is good also as a structure which has a binding tool side through-hole which the axial part of the said fixing | fixed part penetrates. The spine is a spine-side through-hole through which the shaft portion of the fixed portion passes, and the binding-tool-side through-hole is permitted to allow the shaft portion to move in the spine width direction. It is good also as a structure which has in the position substantially corresponding to a hole. The substrate part is provided with a binding tool side through hole, the spine cover is provided with a back cover side through term, and the shaft part of the fixed part described above is passed through these two through holes, so that the substrate part that moves with a simple configuration can be connected to the back part. Can be fixed on the cover. Further, the binding tool side through hole is formed to be larger in size than the spine cover side through hole so that the shaft portion of the fixed portion allows movement in the spine width direction. Therefore, the shaft portion of the fixing portion moves in the binding tool side through hole, and accordingly, the first substrate portion or the second substrate portion pressed by the binding tool pressing portion of the fixing portion moves. That is, at least one of the first substrate portion and the second substrate portion moves within a range in which the shaft portion is allowed to move in the spine width direction.

  Here, in this file, a plurality of the spine side through holes may be provided in the spine width direction of the spine cover. Accordingly, it is possible to adjust the binding amount, that is, the interval between the first substrate portion and the second substrate portion by appropriately selecting the spine side through-hole. Also, in this file, each spine side through-hole is designed to allow the shaft portion to move. Accordingly, a rough binding amount can be set by selecting the spine side through-hole, and the binding amount can be finely adjusted by moving the shaft portion in the selected spine side through-hole.

  In addition, for example, a plurality of spine-side through-holes are provided in the spine width direction, and at least one of the first substrate portion and the second substrate portion is allowed to move in the spine width direction of the shaft portion. You may make it move within the range. According to this file, it is possible to adjust the binding amount, that is, the distance between the first substrate portion and the second substrate portion by appropriately selecting the spine side through hole. Further, since the shaft portion does not move within the selected spine side through-hole, the distance between the first substrate portion and the second substrate portion can be fixed.
