Description

  The present invention relates to a fixing structure between a binding tool and a cover, and a file technology.

  There are a binding tool for binding a document and a technique related to a file including the binding tool. For example, Patent Document 1 discloses a paper binding device. In the paper binding device described in Patent Document 1, the cover of the binding book is provided with a paper binding column and a handle for opening and closing the guide column. It is tight. The mounting bracket is formed by folding semicircular ridges at right angles to the U-shaped passage at both ends of a strip-shaped iron plate having a U-shaped passage into which the gradient plug is pushed. When such a mounting bracket is inserted into the hole provided in the cover and the hole provided in the base of the paper binding device, the hook stops under the cover and only the U-shaped passage into which the gradient plug is pushed becomes a table. Protruding. When the slope plug is pushed into the U-shaped passage projecting from the narrow tip to the top of the paper binding device, both ends of the gradient plug become a kind of scissors. As a result, the cover and the paper binding device are tightly attached.

  Also, for example, in Patent Document 2, a binding tool including a base fixed to a fixed surface such as a back cover and a binding member provided on the base is detachably fixed to the fixed surface. A base fixing structure is disclosed. In the base fixing structure of Patent Document 2, holes are formed in the fixed surface and the base, respectively, and a base fixing tool for fixing the base to the fixed surface via a portion extending into these holes is provided. The base fixture includes a first fixture that includes a vertical portion located in the hole and an outer portion that is connected to the vertical portion and can be located on the outer surface side of the fixed surface, and the first fixture. It consists of the 2nd fixing tool provided in the tool so that attachment or detachment was possible. When the second fixing device is relatively displaced with respect to the first fixing device with the outer portion being attached to the outer surface of the fixing surface, the fixing devices are engaged with each other so that the base and the fixing device are fixed.

  In the technique described in Patent Document 1, it is necessary to insert the mounting bracket into the hole provided in the cover and the hole provided in the base of the paper binding device, and further to push the gradient plug into the U-shaped passage of the mounting bracket. is there. On the other hand, in the technique described in Patent Document 2, the first fixing tool (hook member 43) and the second fixing tool are different from the technique described in Patent Document 1 in which the slope plug is pushed into the U-shaped passage of the mounting bracket. (Rotating member 44) is assembled in a connected state, and the user needs to rotate the second fixing tool to a horizontal state so that the spine and the binding tool are sandwiched and fixed (for example, Patent Literature 2 paragraph 0024). As described above, in the technique described in Patent Document 2, in order to attach and fix the binding tool to the spine, for example, it is necessary to assemble the first fixing tool and the second fixing tool. The work of attaching to the back cover was complicated.

  This invention is made | formed in view of such a point, and makes it a subject to provide the technique which can attach and detach a binding tool more easily than before.

The present invention employs the following means in order to solve the above problems. Specifically, the present invention is a fixing structure in which a fixing surface of a binding tool provided with a binding member is opposed to a fixed surface of a cover and is fixed by a fixing tool, and the substrate has a substrate hole. The cover has a cover hole, and the fixing device is connected to the vertical portion through the substrate hole and the cover hole, and is fixed to the cover in the state of passing through the vertical portion. A first fixture having an attachment portion that is attached to an opposite surface of the surface; and a second fixture that is detachable from the first fixture and is slidable on the substrate. When the second fixture is relatively displaced with respect to the first fixture in a state where the vertical portion penetrates the substrate hole and the cover hole, the fixtures are engaged with each other to form the substrate. And sandwich the cover.

  According to the present invention, the second fixture is slid relative to the first fixture by sliding the second fixture on the substrate with the vertical portion passing through the substrate hole and the cover hole. Thus, the fixtures engage with each other to sandwich the substrate and the cover. That is, it is possible to attach the binding tool to the cover or remove the binding tool from the cover by a simple operation of sliding the second fixing tool on the substrate. Moreover, since the binding tool can be removed from the cover, the cover can be stacked and accommodated. As a result, the size of the cardboard for storing the cover can be reduced as compared with the case of storing the cover with the binding tool fixed. Therefore, transportation cost and storage cost can be reduced.

  Further, the second fixture is regulated to be slidable between a first position and a second position on the substrate by a sliding guide wall standing on the substrate, and is in the first position. Engaging with the vertical portion that penetrates the substrate hole and the cover hole, and when in the second position, an engagement protrusion provided on the surface of the second fixture that contacts the substrate; The second fixing tool and the substrate may be fixed by engaging with an engagement hole provided at a predetermined position on the substrate.

  Since the second fixture is regulated so as to be slidable by the sliding guide wall erected on the substrate, the second fixture can be easily slid along the sliding guide wall. Moreover, since the sliding range is regulated and does not fall off, the second fixture is not lost. In addition, the binding tool can be attached to the cover or removed from the cover simply by sliding the second fixing tool between the first position and the second position. The first position can function as a position for fixing the binding tool to the cover. In the first position, the second fixing tool engages with the vertical portion that passes through the substrate hole and the cover hole, so that the binding tool can be firmly fixed to the cover. Further, the second position can function as a position for removing the binding tool from the cover. In the second position, the second fixing tool and the substrate are fixed, and the state in which the binding tool is removed from the cover is maintained. Therefore, the binding tool can be easily removed from the cover.

  Further, the engaging protrusion may be provided on the distal end side of a flexible flexible plate piece that is connected to and extends from the second fixture. Since the engaging protrusion protrudes from the flexible plate piece, the engaging protrusion can move within a range in which the bending of the flexible plate piece is allowed. Further, the moving range of the engaging protrusion can be increased on the distal end side than on the proximal end side. As a result, in the engagement state between the engagement protrusion and the engagement hole, the engagement protrusion reliably enters the engagement hole, so that the engagement state can be maintained. Even when the engaging protrusion enters the engagement hole, the flexible plate piece bends when a force is applied to the second fixture, so that the engagement protrusion easily disengages from the engagement hole. can do. That is, the engagement can be easily released.

  In addition, the second fixture may receive a biasing force in a direction from the second position toward the first position on the substrate. Thereby, a 2nd fixing tool is maintained in the state of a 1st position. Since the first position can function as a position for fixing the binding tool to the cover, the binding tool can be firmly fixed to the cover. Further, the binding tool can be easily detached from the cover by simply moving the second fixing tool to the second position against the urging force.

Further, the first fixing tool is provided with a positioning protrusion for positioning with the cover by being inserted into a positioning hole provided in the cover, and the positioning protrusion is When the vertical part passes through the substrate hole and the cover hole, the vertical part is formed so as to protrude from the fixed surface through the cover, and when the second fixture is in the second position, the engagement The protrusion and the engagement hole may be positioned so as to be aligned on the same virtual axis.

  By positioning the positioning protrusions upright on the attachment portion, the first fixing member and the cover can be easily positioned. In addition, the positioning protrusion is positioned so as to line up with the engagement protrusion and the engagement hole on the same virtual axis when the second fixture is in the second position. In other words, the positioning protrusion can be moved to the position of the engagement protrusion or the engagement hole.

  Therefore, the positioning protrusion may pass through the engagement hole when the second fixture is in the second position. Thereby, when the second fixing tool is in the second position, the positioning projection can push in the engagement projection engaged with the engagement hole (the engagement projection entering the engagement hole). it can. As a result, the engagement between the engagement protrusion and the engagement hole can be released. Further, when the second fixture receives a biasing force in the direction from the second position to the first position on the substrate, by releasing the engagement between the engagement protrusion and the engagement hole, The second fixture can be moved to the first position by the biasing force. In other words, since the positioning protrusion is passed through the engagement hole, for example, the second fixing tool can be moved to the first position only by pushing the second fixing tool to the cover side. In other words, the binding tool can be fixed to the cover portion only by pressing the binding tool toward the cover side with the binding tool in the state where the second fixing tool is in the second position.

  The substrate further includes a positioning protrusion, and the cover further includes a positioning hole into which the positioning protrusion is inserted, and the positioning protrusion is inserted into the positioning hole when the positioning protrusion is inserted. The substrate hole and the cover hole may be provided so as to be guided so as to be aligned on substantially the same axis, and may be provided at a position closer to the center than the position of the substrate hole in the substrate.

  Since the positioning protrusion is provided on the substrate, the cover and the binding tool can be positioned without using the first fixing tool. Moreover, since the positioning protrusion is provided at a position different from the board hole, the cover hole can be designed according to the outer shape of the vertical portion. In other words, it is not necessary to make the cover hole larger than necessary. Therefore, the vertical portion can be fitted to the cover hole, and the binding tool can be more stably fixed to the cover. Further, when the cover hole is larger than the outer shape of the vertical part, there is a concern that a gap is generated between the peripheral surface of the vertical part and the inner surface of the cover hole, and the binding tool is not stable. In addition, when the binding tool is rattled, the cover hole may spread due to the impact. By providing the positioning protrusion on the substrate and designing the cover hole according to the outer shape of the vertical portion, the occurrence of such a problem can be suppressed.

  Further, both the area of the substrate hole and the area of the cover hole may be substantially the same as the maximum sectional area of the vertical portion. Thereby, shakiness of what is called a binding tool can be suppressed.

  In addition, the second fixture may have a pressing slide operation unit for the user to push the second fixture from the first position toward the second position at the tip of the fixed position as the first position. Good. The second fixing tool can be easily slid by having the pressing slide operating portion at the tip of the fixing position. As a result, it is possible to more easily attach and remove the binding tool.

  The pressing / sliding operation portion may be erected with respect to a surface where the second fixing tool and the substrate are in contact with each other so as to incline from the contacting surface toward a release position. By tilting, the user's fingers and the like can be applied obliquely, and the operability is improved as compared with the case of a flat surface or a vertical surface.

The second fixture has a wedge portion for engaging with the vertical portion, and the pressing slide operating portion is located at the center in a direction orthogonal to the sliding direction and presses on both sides in the direction. A wedge portion may be disposed so as to surround the slide operation portion. The second fixture can slide along the wedge portion. And since the wedge part is provided so that the press slide operation part may surround both sides of the width direction, when a user pushes in the press slide operation part, the sliding direction (track) is stabilized. As a result, it is possible to more easily attach and remove the binding tool.

  The pressing slide operation unit may have a pressing assist surface for increasing a frictional force between the user's fingers and the like. Thereby, it becomes difficult to slip and operability improves. Also, when removing the binding tool from the cover, push the pressing slide operating part of the second fixing tool connected to the binding tool to move the second fixing tool to the second position, and press and operate the second fixing tool as it is. It is more efficient to grip and lift the part. Since it becomes difficult to slip due to the pressing assist surface, it becomes easy to lift the binding tool connected to the second fixing tool.

  Here, the present invention may be specified as a file including a fixing structure of a binding tool and a cover. Specifically, the present invention relates to a binding tool including a binding member, a cover to which a substrate of the binding tool is fixed, and a fixing surface of the binding tool substrate facing a fixed surface of the cover. A fixing portion for fixing the substrate, wherein the substrate has a substrate hole, the cover has a cover hole, and the fixing device has a vertical portion passing through the substrate hole and the cover hole. A first fixing tool that is connected to the vertical portion and is attached to the opposite surface of the cover surface in the penetrating state, and is detachable from the first fixing tool. A second fixture slidable on the substrate, the second fixture relative to the first fixture with the vertical portion passing through the substrate hole and the cover hole.

In the first embodiment, the pressing slide operation unit 76 is configured so that the fingers and the like are not easily brought into contact with the two pipe pipes 413 extending from the side wall portion 411 of the first binding member when the fingers and the like are pushed in. It protrudes further than the end of the fixture 7. More specifically, even in the second position, the press slide operation unit 76 is positioned at the end of the second fixture 7 so that the press slide operation unit 76 is positioned on the end side in the vertical direction with respect to the pipe pipe 413 in plan view. It protrudes further than the part.

  Moreover, the press slide operation part 76 is comprised by the inclined surface. The inclined surface is inclined so as to gradually increase in the vertical direction from the end side toward the center, in other words, from the first position toward the second position. Furthermore, a pressing assist surface 761 is formed on the inclined surface for increasing the frictional force between the user's fingers and the like. The pressing assist surface 761 of the first embodiment is configured by a plurality of irregularities extending in the left-right direction. The pressing assist surface 761 may be dot-shaped unevenness.

  A notch 77 is formed in the proximal end side of the pressing slide operation portion 76, in other words, in the region between the wedge portions 72. A flexible plate piece 78 having flexibility is formed in the notch 77. The base of the flexible plate piece 78 is continuous with the edge of the edge of the notch 77 that is located on the opposite side of the distal end of the pressing slide operation section 76. The tip is a free end. An engagement protrusion 73 that protrudes toward the back side is formed on the tip side that is a free end. The engagement protrusion 73 is accommodated in the accommodation hole 336 formed in the substrate 33 of the base member 3 when the first position and the first position and the second position are moved. Further, the engagement protrusion 73 is engaged with an engagement hole 335 formed in the substrate 33 of the base member 3 at the second position. The tip of the engagement protrusion 73 is formed with an inclined surface so that it can be easily engaged with the engagement hole 335.

  The urging member receiving portion 74 is in contact with the second leg portion 83 of the urging member 8 and transmits the urging force to the second fixture 7. The urging member receiving portion 74 is configured by a wall extending in the left-right direction that is erected from the back side of the cover portion 75 (see, for example, FIG. 12). The urging member receiving portion 74 has both end portions in the left-right direction connected to the contact portion 71 with the sliding guide wall.

The cover portion 75 has a rectangular plate shape as a whole and covers the urging member 8. The urging member receiving portion 74 is erected on the back side of the cover portion 75. The cover part 75 includes a first cover part 751 and a second cover part 752. The first cover portion 751 is formed at a position lower than the second cover portion 752 so as to be located behind the second cover portion 752 in the second position. On the other hand, the second cover portion 752 has a higher area than the first cover portion 751 and a larger area than the second cover portion 752 so as to cover the first cover portion 751 at the second position. By making the cover portion 75 have such a nested structure as described above, the moving distance between the first position and the second position is ensured in a small space. In addition, an arrow indicating an operation direction is engraved on the surface of the second cover portion 752.

<< How to remove and attach the binding tool >>
Next, the removal and fixing method of the binding tool will be described with the operation of the first fixing tool 6 and the second fixing tool 7. As shown in FIGS. 17, 19, 21, and 22, in the first position, the first fixing tool 6 and the second fixing tool 7 are engaged, and the binding tool 2 is fixed to the spine 11 of the file body 1. Has been. In the first position, the second fixture 7 is urged by the urging member 8, and the two second fixtures 7 are in a separated state. The lower second fixture 7 and the upper second fixture 7 basically perform the same operation except that the direction of the operation is opposite. Therefore, in the following description, the lower second fixture 7 will be described as an example.

  The lower second fixture 7 is urged downward with the receiving portion 74 of the urging member in contact with the second leg portion 83 of the urging member 8. Therefore, the upward movement of the lower second fixture 7 is restricted by the biasing member 8. Further, the contact portion 71 with the sliding guide wall in the second fixture 7 is accommodated in the sliding guide wall 334. Therefore, the movement of the lower second fixture 7 in the left-right direction is restricted by the sliding guide wall 334. Further, the wedge portion 72 of the second fixture 7 is engaged with the vertical portion 61 of the first fixture 6. More specifically, in the first fixture 6, the vertical portion 61 passes through the cover hole 14 formed in the spine cover 11 and the substrate hole 338 formed in the substrate 33 of the base member 3. Further, the guide portion 613 constituting the vertical portion 61 is accommodated in the guide groove 722 of the second fixture 7. Further, in the first position, the back side of the locking plate 612 is in contact with the edge of the guide groove 722, and the end portion from the center in the vertical direction is in contact with the end portion of the cover portion 75. Therefore, the locking plate 612 restricts the movement of the second fixture 7 in the inner direction and the movement of the second fixture 7 in the vertical direction at the first position. As a result, the second fixing tool 7 on the lower side is engaged with the first fixing tool 6 so that the movement in the left-right direction, the inner side, and the lower side is restricted. In other words, in the first position, the lower first fixture 6 is only allowed to move upward against the urging force. Note that the engagement protrusion 73 is accommodated in the accommodation hole 336 formed in the substrate 33 of the base member 3 at the first position.

  When the second fixture 7 is moved from the first position to the second position, the pressing slide operating unit 76 is pushed in with fingers or the like. For the lower second fixture 7, a finger or the like is applied to the inclined surface of the pressing slide operating unit 76 and pushed upward. For example, a thumb is applied to the pressing / sliding operation unit 76 of the lower second fixing tool 7, an index finger is applied to the pressing / sliding operating unit 76 of the upper second fixing tool 7, and the first and second fingers are pulled together. It is good to push in the two fixing tools 7.

When the pressing slide operation unit 76 is pushed in, the second fixture 7 starts moving from the first position toward the second position. Also when moving from the first position to the second position, the lower second fixture 7 is restricted from moving in the left-right direction, the inner side, and the lower side. When approaching the second position, the engagement protrusion 73 formed in the flexible plate piece 78 that is accommodated in the accommodation hole 336 formed in the substrate 33 of the base member 3 and moved in the accommodation hole 336, It contacts the upper edge of the receiving hole 336. Further, when the pressing / sliding operation portion 76 is pushed in, the flexible plate piece 78 is bent inward, and accordingly, the engaging protrusion 73 formed on the flexible plate piece 78 is also moved inward. The engaging protrusion 73 gets over the upper edge of the accommodation hole 336. Further, when the pressing slide operating portion 76 is pushed in, the engaging protrusion 73 formed on the flexible plate piece 78 engages with the engaging hole 335 on the same axis as the receiving hole 336. The position where the engagement protrusion 73 engages with the engagement hole 335 is the second position.

  In the second position, the engagement between the wedge portion 72 of the second fixture 7 and the vertical portion 61 of the first fixture 6 is released. In addition, since the engagement protrusion 73 is engaged with the engagement hole 335, the second position is maintained although the urging force of the urging member 8 acts on the second fixture 7. The guide portion 613 is detached from the guide groove 722, the back side of the locking plate 612 is separated from the edge of the guide groove 722, and the upper end portion of the locking plate 612 is also separated from the end portion of the cover portion 75. In particular, the locking plate 612 restricts the movement of the second fixture 7 in the inner direction at the first position, but this restriction is released. As a result, the binding tool 2 to which the second fixing tool 7 is connected can be moved inward. That is, the binding tool 2 can be detached from the spine 11 of the file body 1.

  When attaching the binding tool 2 to the spine 11 of the file body 1, the operation is basically the reverse of the above. First, the vertical portion 61 of the first fixture 6 is passed through the cover hole 14 formed in the spine cover 11 and the substrate hole 338 formed in the substrate 33 of the base member 3. Next, the second fixing tool 7 is turned to the back side as the binding tool is pushed into the cover side with the binding tool in a state where the second fixing tool is in the second position being brought into contact with the cover fixing position. And pushed. When the second fixture 7 is pushed toward the back side, the engagement protrusion 63 enters the engagement hole 335 formed in the substrate 33 of the binding tool 2. Although the engagement protrusion 73 is accommodated in the engagement hole 335, when the engagement protrusion 63 enters the engagement hole 335, the engagement protrusion 63 becomes the engagement protrusion 73 of the second fixture 7. (Engagement projection 73 entering the engagement hole 335) is pushed in. The pressed engagement protrusion 73 is released from the engagement hole 335. Since the downward biasing force is acting on the lower second fixture 7, the lower second fixture 7 moves downward and reaches the first position. As a result, the binding tool 2 is fixed to the spine 11 of the file body 1.

<< Effect >>
According to the file 10 according to the first embodiment, with the vertical portion 61 of the first fixture 6 penetrating the substrate hole 338 and the cover hole 14, the second fixture 7 is slid on the substrate 33, By relatively displacing the second fixture 7 with respect to the first fixture 6, the first fixture 6 and the second fixture 7 are engaged with each other so that the substrate 33 of the binding tool 2 and the back of the file body 1 are engaged. The cover 11 is sandwiched. That is, the binding tool 2 can be attached to the spine 11 of the file body 1 by a simple operation of sliding the second fixing tool 7 on the substrate 33. Further, when the second fixing tool 7 is pushed toward the back side, the engaging protrusion 63 enters the engaging hole 335 formed in the substrate 33 of the binding tool 2. When the engagement protrusion 63 enters the engagement hole 335, the engagement protrusion 63 pushes the engagement protrusion 73 entering the engagement hole 335, so that the pressed engagement protrusion 73 is engaged. Remove from hole 335. Since the downward biasing force is acting on the lower second fixture 7, the lower second fixture 7 moves downward and reaches the first position. In other words, the binding tool 2 can be fixed to the spine 11 of the file body 1 by a simple operation of pushing the second fixing tool 7 back.

  Moreover, since the binding tool 2 can be removed from the file main body 1, the file main body 1 can be accommodated in piles. As a result, the size of the cardboard for storing the file main body 1 can be reduced as compared with the case of storing the file main body 1 to which the binding tool 2 is fixed. Therefore, transportation cost and storage cost can be reduced.

  Moreover, since the 2nd fixing tool 7 is connected to the board | substrate 33 of the binding tool 2, the 2nd fixing tool 7 is not lost. Further, the second fixing tool 7 receives a biasing force in the direction from the second position toward the first position on the substrate 33 of the binding tool 2. Therefore, since the 2nd fixing tool 7 is maintained in the state of a 1st position, the binding tool 2 can be firmly fixed to the spine 11 of the file main body 1. FIG.

In addition, since the positioning protrusion 331 is provided on the substrate 33, the spine 11 of the cover body 1 and the binding tool 2 can be positioned without using the first fixture 6. Further, since the positioning protrusion 331 is provided at a position different from the board hole 338, the cover hole 14 can be designed according to the outer shape of the vertical portion 61. In other words, it is not necessary to make the cover hole 14 larger than necessary. Therefore, the vertical part 61 can be fitted to the cover hole 14, and the binding tool 2 can be fixed to the spine cover 11 more stably. Further, when the cover hole 14 is larger than the outer shape of the vertical part 61, there is a concern that a gap is generated between the peripheral surface of the vertical part 61 and the inner surface of the cover hole 14, and the binding tool 2 is rattled. Further, when the binding tool 2 is rattled, the cover hole 14 may be expanded due to the impact. By providing the positioning protrusion 331 on the substrate 33 and designing the cover hole 14 according to the outer shape of the vertical portion 61, the occurrence of such a problem can be suppressed.

  Moreover, the 2nd fixing tool 7 can be made to slide easily because the 2nd fixing tool 7 has the press slide operation part 76 at the fixed position side front end. As a result, the binding tool 2 can be attached and detached more easily. Further, since the press slide operation unit 76 is inclined, the user's fingers can be applied obliquely, and the operability is improved as compared with the case of a flat surface or a vertical surface.

  Further, the second fixture 7 can slide along the wedge portion 72. And since the wedge part 72 is provided so that the both sides of the width direction of the press slide operation part 76 may be provided, when a user pushes in the press slide operation part 76, the direction (trajectory) to slide is stabilized. As a result, the binding tool 2 can be attached and detached more easily.

  The pressing slide operating unit 76 has a pressing assist surface 761 for increasing the frictional force between the user's fingers and the like. Therefore, it becomes difficult to slip and operability is improved. Further, when removing the binding tool 2 from the spine cover 11, the pressing / sliding operation portion 76 of the second fixing tool 7 connected to the binding tool 2 is pushed to move the second fixing tool 7 to the second position, and the first fixing tool 2 is moved as it is. It is more efficient to grip and lift the pressing / sliding operation portion 76 of the two fixtures 7. Since the pressing assist surface 761 makes it difficult to slip, the binding tool 2 connected to the second fixture 7 can be easily lifted.

  The file 10 according to the first embodiment may have a simpler configuration by omitting, for example, the urging member 8, the first fixing piece 332 of the urging member, and the second fixing piece 333 of the urging member. . Moreover, although the 1st fixing tool 6 is provided with the two perpendicular | vertical parts 61 and the engagement protrusion part 63, it is good also as the separate attachment part 62, respectively, and it is good also as another part. Further, for example, the engaging protrusion 63 may be provided on the inner surface of the spine cover 11.

Further, the contact portion 71 with the sliding guide wall in the second fixture 7 is accommodated in the sliding guide wall 334. Therefore, the movement of the upper second fixture 7 in the left-right direction is restricted by the sliding guide wall 334. Further, the wedge portion 72 of the upper second fixture 7 is engaged with the vertical portion 61 of the first fixture 6. Therefore, the vertical portion 61 restricts the movement of the second fixing tool 7 in the inner direction and restricts the upward movement of the second fixing tool 7 at the first position. As a result, the upper second fixing tool 7 is engaged with the first fixing tool 6 to restrict the movement in the left-right direction, the inner side, and the upper side. In other words, in the first position, the upper first fixture 6 is only allowed to move downward against the urging force. Note that the engagement protrusion 73 is accommodated in the accommodation hole 336 formed in the substrate 33 of the base member 3 at the first position.

  When the second fixture 7 is moved from the first position to the second position, the pressing slide operating unit 76 is pushed in with fingers or the like. As for the lower second fixture 7, a finger or the like is applied to the inclined surface of the pressing slide operation unit 76 and pushed downward. For example, the index finger is applied to the pressing slide operation unit 76 of the upper second fixing tool 7, the thumb is applied to the pressing slide operation unit 76 of the lower second fixing tool 7, and the first and second fingers are pulled together. It is good to push in the two fixing tools 7.

When the pressing slide operation unit 76 is pushed in, the second fixture 7 starts moving from the first position toward the second position. Even when moving from the first position to the second position, the upper second fixing tool 7 is restricted from moving in the left-right direction, the inner side, and the upper side. When the movement to the second position is started, the engaging protrusion 73 formed in the flexible plate piece 78 accommodated in the accommodation hole 336 contacts the lower edge of the accommodation hole 336. Further, when the pressing / sliding operation portion 76 is pushed in, the flexible plate piece 78 is bent inward, and accordingly, the engaging protrusion 73 formed on the flexible plate piece 78 is also moved inward. Then, the engaging protrusion 73 gets over the lower edge of the accommodation hole 336. Further, the press slide operation unit 76.
Is pushed, the engaging protrusion 73 formed on the flexible plate piece 78 engages with the engaging hole 335 on the same axis as the receiving hole 336. The position where the engagement protrusion 73 engages with the engagement hole 335 is the second position.

  24 and FIG. 25, the engagement between the wedge portion 72 of the second fixture 7 and the vertical portion 61 of the first fixture 6 is released at the second position as in the second fixture 7 on the lower side of FIGS. . In addition, since the engagement protrusion 73 is engaged with the engagement hole 335, the second position is maintained although the urging force of the urging member 8 acts on the second fixture 7. As a result, the binding tool 2 to which the second fixing tool 7 is connected can be moved inward. That is, the binding tool 2 can be detached from the spine 11 of the file body 1.

  When attaching the binding tool 2 to the spine 11 of the file body 1, the operation is basically the reverse of the above. First, the vertical portion 61 of the first fixture 6 is passed through the cover hole 14 formed in the spine cover 11 and the substrate hole 338 formed in the substrate 33 of the base member 3. Next, the second fixture 7 is pushed toward the back side. When the second fixture 7 is pushed toward the back side, the engagement protrusion 63 enters the engagement hole 335 formed in the substrate 33 of the binding tool 2. Although the engagement protrusion 73 is accommodated in the engagement hole 335, when the engagement protrusion 63 enters the engagement hole 335, the engagement protrusion 63 becomes the engagement protrusion 73 of the second fixture 7. (Engagement projection 73 entering the engagement hole 335) is pushed in. The pressed engagement protrusion 73 is released from the engagement hole 335. Since the downward biasing force is acting on the lower second fixture 7, the lower second fixture 7 moves downward and reaches the first position. As a result, the binding tool 2 is fixed to the spine 11 of the file body 1.

  According to the file 10 according to the second embodiment, with the vertical portion 61 of the first fixture 6 penetrating the substrate hole 338 and the cover hole 14, the second fixture 7 is slid on the substrate 33, By relatively displacing the second fixture 7 with respect to the first fixture 6, the first fixture 6 and the second fixture 7 are engaged with each other so that the substrate 33 of the binding tool 2 and the back of the file body 1 are engaged. The cover 11 is sandwiched. That is, the binding tool 2 can be attached to the spine 11 of the file body 1 by a simple operation of sliding the second fixing tool 7 on the substrate 33. Further, when the second fixing tool 7 is pushed toward the back side, the engaging projection 63 enters the engaging hole 335 formed in the substrate 33 of the binding tool 2. When the engagement protrusion 63 enters the engagement hole 335, the engagement protrusion 63 pushes the engagement protrusion 73 entering the engagement hole 335, so that the pressed engagement protrusion 73 is engaged. Remove from hole 335. For example, since the downward biasing force is acting on the lower second fixture 7, the lower second fixture 7 moves downward to reach the first position. In other words, the binding tool 2 can be fixed to the spine 11 of the file body 1 by a simple operation of pushing the second fixing tool 7 back.

  Moreover, since the binding tool 2 can be removed from the file main body 1, the file main body 1 can be accommodated in piles. As a result, the size of the cardboard for storing the file main body 1 can be reduced as compared with the case of storing the file main body 1 to which the binding tool 2 is fixed. Therefore, transportation cost and storage cost can be reduced.

  Moreover, since the 2nd fixing tool 7 is connected to the board | substrate 33 of the binding tool 2, the 2nd fixing tool 7 is not lost. Further, the second fixing tool 7 receives a biasing force in the direction from the second position toward the first position on the substrate 33 of the binding tool 2. Therefore, since the 2nd fixing tool 7 is maintained in the state of a 1st position, the binding tool 2 can be firmly fixed to the spine 11 of the file main body 1. FIG.

Further, since the positioning protrusion 68 is provided on the first fixing tool 6, the spine cover 11 of the cover main body 1 and the binding tool 2 can be positioned without providing the positioning protrusion 331 on the substrate 33. Further, since the positioning protrusion 68 is provided at a position different from the board hole 338, the cover hole 14 can be designed according to the outer shape of the vertical portion 61. In other words, it is not necessary to make the cover hole 14 larger than necessary. Therefore, the vertical part 61 can be fitted to the cover hole 14, and the binding tool 2 can be fixed to the spine cover 11 more stably. Further, when the cover hole 14 is larger than the outer shape of the vertical part 61, there is a concern that a gap is generated between the peripheral surface of the vertical part 61 and the inner surface of the cover hole 14, and the binding tool 2 is rattled. Further, when the binding tool 2 is rattled, the cover hole 14 may be expanded due to the impact. By providing the positioning protrusion 68 on the first fixture 6 and designing the cover hole 14 according to the outer shape of the vertical portion 61, the occurrence of such a problem can be suppressed.

  Moreover, the 2nd fixing tool 7 can be made to slide easily because the 2nd fixing tool 7 has the press slide operation part 76 at the fixed position side front end. As a result, the binding tool 2 can be attached and detached more easily. Further, since the press slide operation unit 76 is inclined, the user's fingers can be applied obliquely, and the operability is improved as compared with the case of a flat surface or a vertical surface.

  Further, the second fixture 7 can slide along the wedge portion 72. And since the guide groove 722 of the wedge part 72 is provided so that the both sides of the width direction of the press slide operation part 76 may be provided, when a user pushes in the press slide operation part 76, it slides (trajectory). Is stable. As a result, the binding tool 2 can be attached and detached more easily.

  The pressing slide operating unit 76 has a pressing assist surface 761 for increasing the frictional force between the user's fingers and the like. Therefore, it becomes difficult to slip and operability is improved. Further, when removing the binding tool 2 from the spine cover 11, the pressing / sliding operation portion 76 of the second fixing tool 7 connected to the binding tool 2 is pushed to move the second fixing tool 7 to the second position, and the first fixing tool 2 is moved as it is. It is more efficient to grip and lift the pressing / sliding operation portion 76 of the two fixtures 7. Since the pressing assist surface 761 makes it difficult to slip, the binding tool 2 connected to the second fixture 7 can be easily lifted.

  The file 10 according to the first embodiment may have a simpler configuration by omitting, for example, the urging member 8, the first fixing piece 332 of the urging member, and the second fixing piece 333 of the urging member. . Further, for example, the engaging protrusion 63 may be provided on the inner surface of the spine cover 11.

<< How to remove and attach the binding tool >>
Next, the removal and fixing method of the binding tool will be described with the operation of the first fixing tool 6 and the second fixing tool 7. As shown in FIGS. 33, 34, 40, and 41, in the first position, the first fixing tool 6 and the second fixing tool 7 are engaged, and the binding tool 2 is fixed to the spine 11 of the file body 1. Has been. The lower second fixture 7 and the upper second fixture 7 basically perform the same operation except that the direction of the operation is opposite. Therefore, in the following description, the lower second fixture 7 will be described as an example.

  In the lower second fixture 7, the contact portion 71 with the sliding guide wall is accommodated in the sliding guide wall 334. Therefore, the movement of the lower second fixture 7 in the left-right direction is restricted by the sliding guide wall 334. Further, the wedge portion 72 of the second fixture 7 is engaged with the vertical portion 61 of the first fixture 6. More specifically, in the first fixture 6, the vertical portion 61 passes through the cover hole 14 formed in the spine cover 11 and the substrate hole 338 formed in the substrate 33 of the base member 3. Further, the guide portion 613 constituting the vertical portion 61 is accommodated in the guide groove 722 of the second fixture 7. Further, in the first position, the back side of the locking plate 612 is in contact with the edge of the guide groove 722, and the end portion from the center in the vertical direction is in contact with the end portion of the cover portion 75. Therefore, the locking plate 612 restricts the movement of the second fixture 7 in the inner direction and the movement of the second fixture 7 in the vertical direction at the first position. As a result, the second fixing tool 7 on the lower side is engaged with the first fixing tool 6 so that the movement in the left-right direction, the inner side, and the lower side is restricted. In other words, at the first position, the lower first fixture 6 is only allowed to move upward. Note that the engagement protrusion 73 is accommodated in the accommodation hole 336 formed in the substrate 33 of the base member 3 at the first position.

  When the second fixture 7 is moved from the first position to the second position, the pressing slide operating unit 76 is pushed in with fingers or the like. For the lower second fixture 7, a finger or the like is applied to the inclined surface of the pressing slide operating unit 76 and pushed upward. For example, a thumb is applied to the pressing / sliding operation unit 76 of the lower second fixing tool 7, an index finger is applied to the pressing / sliding operating unit 76 of the upper second fixing tool 7, and the first and second fingers are pulled together. It is good to push in the two fixing tools 7.

  When the pressing slide operation unit 76 is pushed in, the second fixture 7 starts moving from the first position toward the second position. Also when moving from the first position to the second position, the lower second fixture 7 is restricted from moving in the left-right direction, the inner side, and the lower side. When the movement to the second position is started, the engaging protrusion 73 formed in the flexible plate piece 78 accommodated in the accommodation hole 336 contacts the upper edge of the accommodation hole 336. Further, when the pressing / sliding operation portion 76 is pushed in, the flexible plate piece 78 is bent inward, and accordingly, the engaging protrusion 73 formed on the flexible plate piece 78 is also moved inward. The engaging protrusion 73 gets over the upper edge of the accommodation hole 336. Further, when the pressing slide operating portion 76 is pushed in, the engaging protrusion 73 formed on the flexible plate piece 78 engages with the engaging hole 335 on the same axis as the receiving hole 336. The position where the engagement protrusion 73 engages with the engagement hole 335 is the second position.

In the second position, the engagement between the wedge portion 72 of the second fixture 7 and the vertical portion 61 of the first fixture 6 is released. Moreover, since the engagement protrusion 73 is engaged with the engagement hole 335, the second position is maintained. The guide portion 613 is detached from the guide groove 722, and the back side of the locking plate 612 is also the guide groove 722.
The upper end portion of the locking plate 612 is also separated from the end portion of the cover portion 75. In particular, the locking plate 612 restricts the movement of the second fixture 7 in the inner direction at the first position, but this restriction is released. As a result, the binding tool 2 to which the second fixing tool 7 is connected can be moved inward. That is, the binding tool 2 can be detached from the spine 11 of the file body 1.

  When attaching the binding tool 2 to the spine 11 of the file body 1, the operation is basically the reverse of the above. First, the vertical portion 61 of the first fixture 6 is passed through the cover hole 14 formed in the spine cover 11 and the substrate hole 338 formed in the substrate 33 of the base member 3. Next, force is applied so that the second fixtures 7 are separated from each other. As a result, the engagement protrusion 73 gets over the edge of the engagement hole 335 and is detached from the engagement hole 335. Then, the lower second fixture 7 moves downward and reaches the first position. That is, the engagement protrusion 73 is accommodated in the accommodation hole 336. As a result, the binding tool 2 is fixed to the spine 11 of the file body 1. In addition, in order to make it easy to move the second fixture 7 from the second position to the first position, the pressing slide operation portion 76 may be provided at the end portion on the opposite side of the second fixture 7.

<< Effect >>
According to the file 10 according to the third embodiment, with the vertical portion 61 of the first fixture 6 penetrating the substrate hole 338 and the cover hole 14, the second fixture 7 is slid on the substrate 33, By relatively displacing the second fixture 7 with respect to the first fixture 6, the first fixture 6 and the second fixture 7 are engaged with each other so that the substrate 33 of the binding tool 2 and the back of the file body 1 are engaged. The cover 11 is sandwiched. That is, the binding tool 2 can be attached to or removed from the spine 11 of the file body 1 by a simple operation of sliding the second fixing tool 7 on the substrate 33.

  Moreover, since the binding tool 2 can be removed from the file main body 1, the file main body 1 can be accommodated in piles. As a result, the size of the cardboard for storing the file main body 1 can be reduced as compared with the case of storing the file main body 1 to which the binding tool 2 is fixed. Therefore, transportation cost and storage cost can be reduced. Moreover, since the 2nd fixing tool 7 is connected to the board | substrate 33 of the binding tool 2, the 2nd fixing tool 7 is not lost.

  Moreover, the 2nd fixing tool 7 can be made to slide easily because the 2nd fixing tool 7 has the press slide operation part 76 at the fixed position side front end. As a result, it is possible to easily attach and remove the binding tool 2. Further, since the press slide operation unit 76 is inclined, the user's fingers can be applied obliquely, and the operability is improved as compared with the case of a flat surface or a vertical surface.

  Further, the second fixture 7 can slide along the wedge portion 72. And since the wedge part 72 is provided so that the both sides of the width direction of the press slide operation part 76 may be provided, when a user pushes in the press slide operation part 76, the direction (trajectory) to slide is stabilized. As a result, the binding tool 2 can be attached and detached more easily.

  The pressing slide operating unit 76 has a pressing assist surface 761 for increasing the frictional force between the user's fingers and the like. Therefore, it becomes difficult to slip and operability is improved. Further, when removing the binding tool 2 from the spine cover 11, the pressing / sliding operation portion 76 of the second fixing tool 7 connected to the binding tool 2 is pushed to move the second fixing tool 7 to the second position, and the first fixing tool 2 is moved as it is. It is more efficient to grip and lift the pressing / sliding operation portion 76 of the two fixtures 7. Since the pressing assist surface 761 makes it difficult to slip, the binding tool 2 connected to the second fixture 7 can be easily lifted.

  In addition, although the 1st fixing tool 6 is provided with the two vertical parts 61, it is good also as the separate attachment part 62, respectively, and it is good also as another part.

  The preferred embodiments of the present invention have been described above, but it is obvious to those skilled in the art that the binding structure and the file cover and the file according to the present invention can be variously changed, improved, combined, and the like. .
