Description

  The present invention relates to a technique of a binding tool that is detachably attached to a cover body.

  In binders that bind and store documents and paper pieces, a binding tool is fixed inside the back cover of the cover body. As this binding tool, various types have been conventionally known. For example, in a thick binder capable of binding a large number of documents, there is a binding tool as described in Patent Document 1 previously filed by the present applicant.

  As shown in FIG. 11, the binding tool includes a binding tool main body 131 integrally formed of a resin having a self-hinge function and a support bar 132 that holds the binding tool main body 131 in a bound state. . The binding body 131 has side plates 135 and 136 connected to both sides of a bottom plate 133 via hinges 134. One side plate 135 has two binding tubes 137a and 137b inserted into a punch hole of a document. The other side plate 136 is formed with holes 138a and 138b into which the tips of the spelling tubes 137a and 137b are inserted.

  The bottom plate 133 of the binding tool main body 131 has a locking hole 142a for locking the fastening rivet 119 attached to the back cover of the mount (cover), and an open hole through which the fastening rivet 119 can pass. Position restricting means 142 including 142b, a locking hole 142a, and a guide groove 142c that connects the opening hole 142b is provided.

In order to attach the binding tool 130 having such a configuration to the mount, the fastening rivet 119 fixed by the two-position restricting means 121 of the mount is inserted into the opening hole 142b which is the second open position of the two-position restricting means 142. Corresponding insertions are made, and the binding tool 30 is moved downward. As a result, the flange portion 119c of the fastening rivet 119 passes through the guide groove portion 142c of the two-position restricting means 142, ascends the inclined surface 142d, moves to the locking hole portion 142a that is the first locking position, and the flange portions 119b, 119b, The binding plate 130 is locked to the mount by holding the bottom plate 133 by 119c.
Japanese Patent Laid-Open No. 11-188981

  By the way, even if the binder having the above configuration is subjected to an impact from the outside such as dropping in a state where the maximum number of documents of the binding tool 130 is bound, the flange portion 119c of the fastening rivet 119 is locked. As long as it does not move from the hole 142a, the binding tool 130 can be fixed to the mount.

  However, if an excessive impact is applied in the vicinity of the locking hole 142a of the binding tool 130 that is in contact with the fastening rivet 119 due to dropping or the like, the fastening rivet 119 or the vicinity of the locking hole 142a may be damaged. . When the fastening rivet 119 is made of metal, the locking hole 142a is more easily damaged.

  Then, the present applicant made it the subject of this invention to provide the binding tool which can prevent the damage of the binding tool by impacts, such as dropping.

Further, the binder having the above configuration fixes the binding tool 130 to the mount by the fastening rivet 119. Therefore, it is preferable to use a tool for attaching and removing the fastening rivet 119 when attaching or removing the binding tool 130 to the mount, and a binding tool that can more easily attach and detach the binding tool is desired. It was.

  Then, the present applicant made it the further subject of this invention to provide the binding tool which can perform attachment / detachment operation of a binding tool easily.

  The present invention has been made in view of the above problems, that is, the present invention is a binding device having a substrate portion that is detachably attached to a cover body, and is provided on the inner surface side of the cover body provided on the substrate portion. A through-hole penetrating the provided base member; a slide portion adjacent to the through-hole, sliding the substrate portion to engage with the base member; and an engagement state of the slide portion and the base member with respect to the substrate portion It is characterized by comprising a regulating member that regulates relative movement between the slide portion and the base member by filling the movement space in the sliding direction.

  The base member according to the present invention is inserted into a through hole provided in the binder back cover and the substrate portion of the binding tool and protrudes on the substrate portion, and a plurality of protrusions provided on both sides thereof are formed. ing. In addition, the slide portion according to the present invention is formed with a plurality of grooves that fit into the protrusions when mounted on the base member.

  That is, when the slide part is mounted on the base member, the protrusion of the base member is inserted into the groove of the slide part. Then, the restricting member according to the present invention has a space in the entry direction of the protrusion (the movement of the slide part in the slide direction with respect to the substrate part) in order to keep the protrusion of the base member entering the groove of the slide part. It is arranged at a position to fill the (space) and restricts relative movement between the slide portion and the base member. This restriction member is designed so that the restriction of the engagement state between the slide part and the base member is released by applying an excessive load in the sliding direction when the slide part is mounted on the base member.

  Therefore, when the binder is dropped in a state where a large amount of documents are bound, or when an impact is applied to the binding tool, the restriction of the relative movement between the slide portion and the base member by the restriction member is released, and the binding tool is released. It itself disengages from the base member.

  As described above, when an excessive force is applied to the binding tool, the binding tool is detached from the base member, so that the binding tool can be prevented from being damaged by a load.

  In addition, the regulating member according to the present invention is connected to the base plate portion so as to be rotatable via a thin hinge, and the regulating member rotates to the base member side with the thin hinge as a pivot shaft on the base plate portion, and slides. In a state where the relative movement between the portion and the base member is restricted, it is preferable that a locking portion for locking the restriction member is further provided.

  This locking portion prevents the regulating member from inadvertently releasing the engaged state between the slide portion and the base member.

  That is, the binding device of the present invention maintains a state in which the slide portion and the base member are mounted in a normal use state (a state in which an excessive load is not applied), and an excessive load is applied due to a fall of the binder or the like. When the binding device is added, the locking portion and the regulating member are unlocked, and the attachment of the slide portion and the base member is also released accordingly, so that the binding device is detached from the cover body.

  Further, although the thin hinge portion is uneasy about the strength against an excessive load, the binding device of the present invention can release the load applied to the thin hinge by the inclined surface of the convex portion as described above. Damage to the part can be prevented.

  Therefore, according to the present invention, the restriction member and the substrate portion are integrally formed through the thin hinge, so that the number of parts of the binding tool is small, and the production cost of the binding tool can be reduced.

  Furthermore, a face plate portion facing the base member is provided on the free end side of the restriction member according to the present invention in a state in which the restriction member rotates around the thin hinge and is locked to the locking portion. In addition, the relative movement can be regulated by the face plate portion coming into contact with the base member.

  In this case, it is more preferable that the locking portion is in a direction facing the face plate portion. For example, when the locking portion is provided on the base member side and is in a direction facing the face plate portion, the restricting member rotates around the thin hinge as a rotation shaft to restrict relative movement between the slide portion and the base member. At this time, the locking portion is in a state of locking the end portion of the regulating member. At this time, when the face plate portion is pressed against the base member due to the dropping of the binder or the like, the regulating member is applied with a force on the thin hinge side and moves to the thin hinge side. Then, the locking part and the end of the regulating member are separated from each other, and the end of the regulating member is released from the locked state by the locking part.

  In this manner, the correlation between the locking portion and the face plate portion can facilitate the movement of the slide member relative to the base member when an excessive load is applied, and consequently prevents damage to the binding device. Can do.

  The substrate portion of the present invention further includes a convex portion protruding from the surface of the substrate portion between the locking portion and the thin hinge, and the restricting member rotates the restricting member toward the base member with the thin hinge as a rotation shaft. It is preferable that a contact portion that contacts the convex portion in a moved state is further provided, and the convex portion is inclined from the top portion toward the slide portion.

  The contact part provided in the regulating member is located between the locking part and the convex part. Therefore, when a force is applied in a direction in which the protruding portion of the base member is removed from the groove of the slide portion, and the face plate portion is pushed by the base member, the contact portion moves toward the convex portion. Further, the contact portion moves along the inclined surface of the convex portion.

  When the face plate portion is pressed by the base member, the force is transmitted to the regulating member, and the load is applied to the thin hinge. The load acts on the thin-walled hinge and causes the thin-walled hinge to be damaged, but the load can be released by the contact portion of the restricting member moving along the inclined surface of the convex portion. Thereby, the load concerning a thin hinge can be reduced and damage to a thin hinge can be prevented.

  Furthermore, it is preferable to provide an operation portion for rotating the restriction member about the thin hinge as a turning shaft on the free end side of the restriction member according to the present invention.

  The operation part according to the present invention is one that extends from the end part of the restricting member, or the one that faces the substrate part when the restricting member is turned and bent toward the substrate part side with the thin hinge as a turning shaft. It can be a concave recess provided on the surface of the regulating member.

  This operation part is operated when the user intentionally releases the fitting state between the slide part and the base member. And if the fitting state of a slide part and a base member is cancelled | released, a slide part will detach | leave from a base member and a binding tool will be removed from a binder. That is, by providing the operation unit, the user can easily perform the attaching / detaching operation of the binding tool.

Further, it is more preferable that a finger hooking portion for sliding the substrate portion is further provided at the end of the substrate portion on the side opposite to the thin hinge according to the present invention.

  When the binding tool is slid in the direction in which the slide portion is removed from the base member, the user slides the binding tool by placing a finger on the finger hook portion. By having the finger hook portion, even if the substrate portion is flat, the user can perform an operation of removing the binding tool from the binder with an easy operation using the finger hook portion.

  Further, in the binding device according to the present invention, the restricting member is rotatable via a hinge having a biasing means for guiding the restricting member to a restricting state in which relative movement between the slide portion and the base member is restricted. It is good also as connecting to the substrate part.

  By connecting the restricting member to the substrate portion via a hinge having biasing means for guiding the restricting member to the restricting state, the restricting member is guided to the restricting state semi-automatically. That is, the operation of attaching the substrate portion to the cover sheet becomes easier. The urging means can be constituted by a spring or the like to which an urging force is applied in a direction leading to the restricted state, for example. Further, the strength of the urging force can be set as appropriate, but it is preferable to set the strength so as not to make an operation when releasing the restricted state difficult. Further, the hinge having the urging means can be configured as a separate part from the substrate portion. For example, the hinge can be repeatedly used by being made of metal having excellent strength.

  Further, in the binding device according to the present invention, the urging means is a rotation direction based on a rotation axis of a hinge having the urging means, and the restricting member rotates toward the base member. In addition, the spring may be a spring that biases the restricting member.

  By using the spring as described above as the urging means, the regulating member is urged in the direction in which the regulating member rotates toward the base member, in other words, in the direction in which the regulating member closes with respect to the base member, and the regulating member of the binding device is semi-automatically It becomes possible to be in a regulated state. Moreover, when an excessive force is applied to the binding tool, the restriction by the restriction member is released. Therefore, since the binding tool is detached from the base member, it is possible to prevent the binding tool from being damaged by a load. Note that by setting the urging force to be weak, release by the restriction member is easily performed, and as a result, the binding tool can be easily detached from the cover sheet.

  Moreover, the binding tool which concerns on this invention WHEREIN: The said board | substrate part may be further provided with the latching | locking part which latches the said regulating member in the said regulation state. This locking portion prevents the regulating member from inadvertently releasing the engaged state between the slide portion and the base member.

  Further, in the binding device according to the present invention, the substrate portion further includes a convex portion protruding from the surface of the substrate portion, and the restriction member has a hinge on which the restriction member has the urging means as a rotation shaft. It further has a contact part which contacts the convex part in the state rotated to the base member side, and the convex part inclines toward the hinge side which has the energizing means from the top part. Also good.

  When the substrate portion has the convex portion having the inclined surface, when an excessive force is applied to the binding device, the contact portion comes into contact with the inclined surface of the convex portion and is guided upward along the inclination. That is, the substrate portion (contact portion) is guided in a direction in which the restriction by the restriction member is released. As a result, the binding tool is separated from the cover body. The urging force is preferably set weakly. This is so that the binding tool can be easily detached from the cover body when an excessive force is applied to the binding tool.

As described above, according to the present invention, it is possible to provide a binding device that can prevent the binding device from being damaged by an impact such as dropping.

  Furthermore, according to the present invention, it is possible to provide a binding tool that can be easily attached and detached.

Furthermore, grooves 23a to 23d extending in the direction in which the slide portion 9 is mounted are formed on the lower surfaces of the engaging portions 22a to 22d, respectively.

  Next, the slide part 9 will be described in detail. As shown in FIGS. 1 and 2, four slide portions 9 are provided corresponding to the protruding portions 21a to 21d of the base members 20a to 20d (hereinafter, referred to as slide portions 9a to 9d). The slide portions 9a to 9d extend in the insertion direction of the protruding portions 21a to 21d of the base members 20a to 20d on the inner walls of the rectangular through holes formed along the longitudinal direction of the spine B2 of the substrate portion 2. The protruding portions 11a to 11d are respectively formed (see FIG. 6).

  These protrusions 11a to 11d are allowed to enter grooves 23a to 23d provided in the protrusions 21a to 21d of the base members 20a to 20d. That is, the protrusions 11a to 11d are fitted in the grooves 23a to 23d, so that the slide parts 9a to 9d and the base members 20a to 20d are mounted, and the movement in the vertical direction with respect to the slide direction is suppressed. be able to.

  Moreover, the board | substrate part 2 is provided with the regulating member 30 in the direction which makes the protrusion part 11a-11d approach into groove | channel 23a-23d. The restricting member 30 is provided at the end portion of the substrate portion 2 on the slide portions 9a, 9b side (or the protruding portions 21a, 21b side of the base members 20a, 20b). In this embodiment, in the normal use state of the binder B, the side of the binding device 1 on which the regulating member 30 is provided (the side on which the base members 9a and 9b are provided) is the bottom, and the slide portions 9c, The description will be made with the side provided with 9d as the upper side.

  As shown in FIGS. 4 to 6, the regulating member 30 is a plate-like member and is formed integrally with the substrate unit 2. Further, the lower end of the substrate portion 2 becomes a thin hinge 31, and the regulating member 30 is formed through the thin hinge 31. That is, one end (lower end) of the regulating member 30 is formed on the thin hinge 31, and the thin hinge 31 is also formed integrally with the substrate unit 2.

  Therefore, as shown in FIG. 4, the regulating member 30 can be rotated to the face plate side (X direction in FIG. 4) of the substrate portion 2 with the thin hinge 31 as a rotation axis. As shown in FIG. 5, the regulating member 30 is rotated until the surface of the regulating member 30 facing the substrate portion 2 is substantially parallel to the surface of the substrate portion 2.

  Further, the other end (upper end) of the restricting member 30 is rotated with the thin hinge 31 as a turning shaft, and the restricting member 30 is bent so that the face plate faces the protruding portions 21a and 21b of the base members 20a and 20b. Portions 32a and 32b are provided. When the regulating member 30 is bent, a slight space is provided between the face plate portions 32a and 32b and the protruding portions 21a and 21b.

Further, on the substrate portion 2, locking portions 40 a to 40 d are provided that hold the restricting member 30 toward the base members 20 a and 20 b and bend with respect to the substrate portion 2. The locking portions 40a to 40d of the present embodiment have claw portions 41a to 41d that protrude from the end of the board portion 2 on the end points side of the ridge portions 11a and 11b and extend from the apexes toward the regulating member 30 side. Yes. The claw portions 41a to 41d are provided in pairs (locking portion 40a, locking portion 40b and locking portion 40c, locking portion 40d) so as to sandwich the face plate portions 32a and 32b from both sides. And these latching | locking parts 40a-40d hold | suppress the edge part of the control member 30 when the control member 30 is bent in the base member 20a, 20b side from upper direction. In addition, the binding tool 1 of a present Example is formed with resin (for example, polypropylene) except the fixing tool 7. FIG. Therefore, in order to bring the regulating member 30 into the locked state by the locking portions 40a to 40d, the regulating member 30 is rotated to the locking portions 40a to 40d side with the thin hinge 31 as the rotation axis (X in FIG. 7). Direction), as shown in FIG. 8, the claw portions 41 a to 41 d are deformed to position the regulating member 30 below the claw portion 41. Thereby, the restricting member 30 is locked by the locking portions 40a to 40d so as to maintain the restricted state.

  That is, in the binding device 1 of the present embodiment, since the locking portions 40a to 40d lock the restriction member 30 in a normal use state, the slide portions 9a and 9b and the base members 20a and 20b are attached. The state is maintained and the binding device 1 is kept fixed to the spine B2. On the other hand, when an excessive load is applied to the binding device 1 due to the fall of the binder B or the like, the locked state between the locking portions 40a to 40d and the regulating member 30 is released, and accordingly the sliding portions 9a, The mating state between 9b and the base members 20a and 20b is also released, and the binding device 1 is detached from the spine B2. Thereby, breakage of the binding device 1 due to excessive impact can be prevented.

  Furthermore, the relative movement of the slide portions 9a, 9b and the base members 20a, 20b by the user intentionally pulling up the restriction member 30 between the double-sided plate portions 32a, 32b of the restriction member 30 according to the present embodiment. A knob (operating unit) 33 is provided for releasing the restriction. The knob 33 is formed to extend from the end of the regulating member 30 between the double-sided plate portions 32. In addition, it is preferable when the knob | pick part 33 inclines to the near side in the state in which the control member 30 was bent. As a result, the user picks the knob 33 and lifts it up to release the locked state of the restricting member 30, and further restricts relative movement between the slide parts 9a, 9b and the base members 20a, 20b. It can be canceled. That is, the user can easily perform the work of removing the binding tool 1 from the spine cover B2 by the knob 33.

  In addition, a fitting state between the base members 20a to 20d and the slide portions 9a to 9d is provided at an end portion of the binding portion 1 of the present embodiment which is opposite to the end portion where the thin hinge 31 is provided. In order to cancel, the finger hook part 34 for making it easy for a user to slide the binding tool 1 is provided. The finger hook portion 34 is a convex member that is erected from the surface of the substrate portion 2.

  Further, on the substrate portion 2 that faces the locking portions 40a to 40d and sandwiches the regulating member 30 from the left and right sides, convex portions 50a and 50b that protrude from the surface are provided. And between the latching | locking part 40a, 40b and the convex part 50a, and between the latching | locking part 40c, the latching | locking part 40d, and the convex part 50b, contact part 35a, 35b which is a part of the control member 30 is located. To do. The contact portions 35a and 35b come into contact with the convex portions 50a and 50b when an excessive force is applied from the lower side of the spine cover B2. The regulating member 30 is hollowed out on both sides (left and right) so that the convex portions 50a and 50b can be arranged, and the overall shape is substantially T-shaped.

  A rectangular hole 36 is provided in the approximate center of the regulating member 30. When the regulating member 30 is pivoted toward the substrate part 2 with the thin hinge 31 as a pivot axis and is completely bent with respect to the substrate part 2, the convex part 51 entering the hole part 36 is located on the substrate part 2. Is provided. In addition, the hole part 36 will also contact the convex part 51, if excessive force is added from the lower side of spine cover B2 similarly to the contact parts 35a and 35b.

  Further, the convex portion 50 and the convex portion 51 are formed with inclined surfaces 52a and 52b and an inclined surface 53 from the apex of the convex portion 50 and the convex portion 51 toward the slide portions 9a and 9b. These inclined surfaces 52a and 52b and the inclined surface 53 play a large role in order to prevent the binding device 1 from being damaged.

For example, as shown in FIG. 9A, the binder B is dropped, for example, in the direction from the regulating member 30 side to the base member 20a, 20b side (the direction from the bottom to the top of the spine cover B2) (
A case where an excessive force is applied in the Y direction in FIG. 9 will be described.

  When force is applied from the Y direction, as shown in FIG. 9B, the convex portions 50a and 50b move to the contact portions 35a and 35b. The convex portions 50a and 50b (substrate portion 2) are formed of an elastic resin, and the convex portions 50a and 50b move to the contact portions 35a and 35b side due to plastic deformation. When the convex portions 50a and 50b further move toward the contact portions 35a and 35b, the contact portions 35a and 35b are put on the inclined surfaces 52a and 52b of the convex portions 50a and 50b.

  Further, when force continues to be applied in the same direction, the contact portions 35a and 35b move along the inclined surfaces 52a and 52b as shown in FIG. 9C. Accordingly, the contact portions 35a and 35b become the locking portions 40a. It is separated from ˜40d (claw portions 41a to 41d). That is, when the contact portions 35a and 35b move along the inclined surfaces 52a and 52b of the convex portions 50a and 50b, the restricting member 30 is released from the claw portions 41a to 41d, and the locked state is released. The thin hinge 31 is rotated about the rotation axis toward the outside of the substrate portion 2 (the Z direction in FIG. 9C, that is, the direction opposite to the X direction in FIG. 4). Thereby, the restriction | limiting of the relative movement of slide part 9a, 9b and base member 20a, 20b is cancelled | released.

  With such a configuration, when any impact is applied to the binding device 1 from below the spine cover B2 of the binder B, such as when the document is dropped in a state where the document is bound to the binder B, the regulating member The restriction on the relative movement between the slide parts 9a, 9b and the base members 20a, 20b by 30 is released, so that the slide parts 9a-9d can come out of the base members 20a-20d, and the binding tool 1 itself is removed from the back cover B2. Come off.

  In this way, when an excessive force is applied to the binding tool 1 from a predetermined direction, the binding tool 1 is detached from the spine cover B2, so that the binding tool 1 can be prevented from being damaged by a load.

  Moreover, when force is applied to the binding tool 1 from the top to the bottom of the spine cover B2 of the binder B, the base members 20a to 20d are wall portions 12a to 12d (elevated from the slide end points of the slide portions 9a to 9d). (See FIG. 5). Since the wall portions 12a to 12d are erected so as to face the force applied to the binder B, the base members 20a to 20d move further toward the wall portions 12a to 12d even if force is continuously applied from the same direction. I can't.

  That is, even when force is applied to the binding tool 1 from the top to the bottom of the spine cover B2, the state in which the slide portions 9a to 9d and the base members 20a to 20d are mounted is maintained (the restriction state of the restriction member 30). Therefore, the binding device 1 does not come off the binder B.

  Further, when excessive force continues to be applied in the direction from the regulating member 30 side to the base member 20a, 20b side (Y direction in FIG. 9) and the base member 20a, 20b presses the face plate portions 32a, 32b, the pressing force is It acts on the thin hinge 31. The force causes the thin hinge 31 to be damaged, but in the binding device 1 of the present embodiment, the contact portions 35a and 35b of the regulating member 30 move along the inclined surfaces 51a and 51b of the convex portions 50a and 50b. The power can be released.

  Thereby, since the load added to the thin hinge 31 can be reduced, it is possible to prevent the thin hinge 31 from being easily damaged by an impact.

  Moreover, since the binding tool 1 of the present embodiment is integrally formed of resin except for the fixing tool 7, the number of parts constituting the binding tool 1 is small, and the production cost can be reduced.

  The binding tool of the present embodiment is a binding tool for attaching to a binder having a binding thickness of 10 cm or more. In addition, about the structure which is common in the binding tool of Example 1, the same code | symbol is attached | subjected in drawing, and those description is simplified.

  As shown in FIG. 10, the binding device 1 of the present embodiment is different in the structure of the knob portion 33 provided in the binding device 1 of the first embodiment. The knob 33 according to the present embodiment includes a recess 33 formed inward from an end opposite to an end provided with the thin hinge 31 of the regulating member 30 integrally molded with the substrate 2. It has become. The concave portion 33 is in a state in which the relative movement between the slide portions 9a and 9b and a base portion (not shown) is restricted when the restriction member 30 is turned to the surface of the substrate portion 2 with the thin hinge 31 as a turning shaft. ) Of the regulating member 30 from the end portion of the substrate portion 2 toward the face plate portion.

  The user can insert a finger into the recess 33 and lift the restricting member 30 in order to release the restriction of the relative movement between the slide portions 9 a and 9 b and the base member by the restricting member 30.

  Thus, when the binding thickness of the binder is large, the interval between the base member and the base member (protruding part and protruding part) located adjacent to each other in the width direction of the spine cover B2 also becomes wide. Furthermore, since the binding thickness of the binder is thick, the width of the substrate part 2 attached to the spine can be increased, and accordingly, the width of the regulating member 30 formed integrally with the substrate part 2 can be increased. . Thereby, a sufficient space for the user to perform an operation of pulling up the regulating member 30 can be secured.

  Therefore, even if the knob 33 is not formed by extending a part of the edge of the regulating member 30 as in the first embodiment, the user simply uses the fingertip to form the regulating member 30 by forming the recess 33. It becomes easy to catch.

  That is, according to the present embodiment, it is possible to provide a binding tool having an operation unit that is easy for the user to operate in a simpler process than forming the knob portion 33 according to the first embodiment.

  Further, the binding tool 1 of the present embodiment can be formed so that the width of the substrate portion 2 and the width of the regulating member 30 can be widened, so that two protruding portions 50a, 51a (50b, 5b) with respect to one slide portion 9a (9b). ) Is provided. In addition, the same inclined surface as the convex parts 50a, 50b, 51 of Example 1 is formed also in these convex parts 50a, 50b, 51a, 51b. In addition, when the regulating member 30 is pivoted to the surface side of the substrate portion 2 with the thin hinge 31 as a pivot axis, the regulating member 30 can be inserted into the convex portion 51a and the convex portion 51b. Holes 36a and 36b are formed.

  That is, even when the width of the regulating member 30 is wide, the regulating member 30 moves the locking portions 40a to 40d along the plurality of inclined surfaces formed on the convex portions 50a, 50b, 51a, and 51b. Therefore, the operation for releasing the restricted state can be performed stably.

  The binding tool 1 of the third embodiment is different in that a spring hinge 311 is used instead of the thin hinge 31 of the binding tool 1 of the first embodiment. Hereinafter, the binding device according to the third embodiment will be described with reference to the drawings. In addition, about the structure which is common in the binding tool of Example 1, the same code | symbol is attached | subjected in drawing, and those description is simplified.

FIG. 12 is a perspective view showing a restricted state by the restricting member 301. FIG. 13 is a perspective view showing a state in which the restriction state by the restriction member 301 is released. FIG. 14 is a side view of the binding device 1. FIGS. 15A and 15B are longitudinal sectional views of the binding device 1, in which FIG. 15A shows a restricted state and FIG. 15B shows a state where the restricted state is released.

  As shown in FIGS. 12 to 15, the binding device 1 according to the third embodiment is fixed to the inner side surface of the cover body B2 by base members 20e and 20f. The binding device 1 according to the present embodiment includes a substrate portion 2 fixed to the spine B2 of the binder B, and side plates 4a and 4b that are detachably connected to left and right side portions of the substrate portion 2, and the side plate 4a Are provided with binding tubes 5a and 5b, and a document can be bound by inserting a punch hole of the document from the tip of the binding tubes 5a and 5b.

  In addition, a regulating member 301 corresponding to the regulating member 30 of the first embodiment is connected to one end of the substrate unit 2 according to the third embodiment by a spring hinge 311. The spring hinge 311 is made of metal and is configured as a separate component from the board portion 2 and can be used repeatedly. In addition, since the board | substrate part 2 and the spring hinge 311 are separate components, the material of the board | substrate part 2 may be made of metal or resin. Therefore, the base members 20e and 20f that fix the base portion 2 may be made of metal or resin.

  The spring hinge 311 includes a shaft pin 311a and a torsion coil spring 311b. The shaft pin 311a connects the one end portion of the substrate portion 2 and the end portion of the regulating member 301 so as to be rotatable, and functions as a guide rod for the torsion coil spring 311b. The torsion coil spring 311b is a spring that receives a torsional moment about the coil axis, and is constituted by a coiled spring portion and arm portions at both ends, one arm portion being the substrate portion 2 and the other arm portion being a regulating member. 301 is in contact. As a result, when the substrate portion 2 and the regulating member 301 are opened, an urging force (restoring force) acts on the torsion coil spring 311 and the regulating member 301 is guided semi-automatically to the substrate portion 2 side. The strength of the torsion coil spring 311b is preferably set to such a degree that the restricted state is released when an excessive load is applied to the binding tool 1 due to the fall of the binder B or the like. This is because if the spring strength of the torsion coil spring 311b is too strong, the strength leading to the restricted state is increased, but the restricted state is not released even when an excessive load is applied.

  Further, face plate portions 312a and 312b that face the base member 20f in the restricted state are provided at the free end of the restricting member 301. The face plate portions 312a and 312b allow the base member 20f to slide in the restricted state. Can be prevented. Further, a knob portion 33 a is provided between the face plate portions 312 a and 312 b at the free end of the regulating member 301. Thereby, the user can perform the operation | work which removes the binding tool 1 from the back cover B2 easily.

  Note that the convex portions 50a, 50b, 51, the hole 36, and the like described in the first embodiment may also be provided for the binding device 1 in the third embodiment. Thereby, when an excessive force is applied to the binding tool 1 from a predetermined direction, the binding tool 1 is detached from the spine cover B2, so that the binding tool 1 can be prevented from being damaged by a load.

  Next, the base members 20e and 20f in the present embodiment will be described. As described above, the substrate portion 2 and the base members 20e and 20f may be made of resin or metal. Here, the form of the resin base member and the metal base member will be described. Based on

FIG. 16A is a plan view of a resin base member, and FIG. 16B is a side view of the resin base member. The base members 20e and 20f according to the third embodiment are connected to the thin plate-shaped retaining portion 211 disposed outside the back cover B2 and the retaining portion 211 at a substantially right angle, and pass through the back cover B2 and the substrate portion 2. Then, the protruding portion 212 protruding above the substrate portion 2, the locking portion 213 connected to the top of the protruding portion 212 substantially parallel to the retaining portion 211, and the surface of the retaining portion 211 inside the protruding portion 212. And a guide portion 214 that protrudes further toward the locking portion 213. The base members 20e and 20f according to the present embodiment have a simpler configuration than the base members 20a to 20d in the first embodiment described above. That is, when the slide portions 9a to 9d enter between the retaining portion 211 and the retaining portion 213, the movement in the direction perpendicular to the sliding direction is restricted.

  The interval between the protruding portions 212 is set based on the interval between the slide portions 9a and 9b, and the height of the protruding portion 212 is set based on the thickness of the spine cover B2 and the substrate portion 2. Moreover, the latching | locking part 213 is set to the magnitude | size which does not rub through from the slide parts 9a and 9b in a control state. And such a shape can be integrally formed by injection molding by making the base members 20e and 20f into resin.

  FIG. 17A is a plan view of the metal base members 20e and 20f, and FIG. 17B is a side view of the metal base members 20e and 20f. The functions of the metal base members 20e and 20f are the same as those of the resin base members 20e and 20f described above, but their forms are slightly different depending on the characteristics during molding. Specifically, the metallic base members 20e and 20f are also connected to the thin plate-shaped retaining portion 211a disposed on the outer side of the back cover B2 and the retaining portion 211a at a substantially right angle, and the spine cover B2 and the substrate. A protrusion 212a protruding through the portion 2 and protruding onto the substrate portion 2, and a locking portion 213a connected to the top of the protrusion 212a substantially in parallel with the stopper 211a. It has a guide part 214a that is substantially perpendicular to the part 211a and parallel to the inside of the protruding part 212a. And when the slide parts 9a-9d approach between the retaining part 211a and the locking part 213a, the movement in the direction perpendicular to the sliding direction is restricted.

  The protruding portion 212a is formed by raising a part (the notch portion 216) of the retaining portion 211a at a substantially right angle with respect to the retaining portion 211a. Moreover, the latching | locking part 213a is formed by folding up the front-end | tip part of the protruding part 212a raised. The guide part 214a is formed by raising a part (the notch part 215) of the retaining part 211a at a substantially right angle with respect to the retaining part 211a. Thus, the base members 20e and 20f can be formed by pressing a single metal plate. Further, since the base members 20e and 20f are made of metal, they are very excellent in durability.

  According to the binding device 1 according to the third embodiment described above, the regulation member 301 is semi-automatically guided to the regulation state by providing the spring hinge 311, and as a result, the operation of attaching the substrate unit 2 to the cover body B is performed. It becomes easier.

  The binding device 1 of the fourth embodiment is basically the same in configuration as the binding device 1 of the third embodiment, but the embodiment described above in that it has a convex portion 50a corresponding to the convex portion 50 of the first embodiment. 3 is different from the binding tool 1 of FIG. Hereinafter, the binding device according to the fourth embodiment will be described with reference to the drawings. In addition, about the structure which is common in the binding tool of Example 3, the same code | symbol is attached | subjected in drawing, and those description is simplified.

  FIG. 18 is a perspective view illustrating a restricted state by the restricting member 301 of the binding device 1 according to the fourth embodiment. FIG. 19 is a side view of the binding device 1 according to the fourth embodiment. 20 is a longitudinal sectional view showing the convex portion 50a of the binding device 1. FIG. 20A shows a restricted state, FIG. 20B shows a state in which the restricted state is released, and FIG. It is an enlarged view which shows the change to the state from which a control state is cancelled | released.

The convex portion 50 a has a triangular shape in a side view, and is provided on the outer side of the base member 20 f so that the inclined surface 52 a 1 faces the free end of the regulating member 301. The convex portions 50a are arranged at a slight interval so that the inclined surface 52a1 does not come into contact with the free end of the regulating member 301 in a restricted state where no external load is applied. The slight interval is set so that the inclined surface 50a contacts the end portion of the regulating member 301 when a load is applied. Note that the portion of the free end of the regulating member 301 that contacts the slope 52a1 corresponds to the contact portion of the present invention. Moreover, you may provide the inclination part according to the angle of the inclination part 50a in the free end of the control member 301 corresponded to this contact part. By providing such an inclined portion at the free end (contact portion) of the regulating member 301, it is possible to more easily lead to the released state.

  The convex portion 50 a can be formed by forming two cuts extending from the top of the substrate portion 2 and raising the cut triangular portions substantially at right angles to the substrate portion 2. In this case, the thickness of the substrate portion 2 corresponds to the width of the slope 52a1. The angle of the slope 52a1 is preferably set as appropriate in consideration of the spring strength of the coil spring 311b.

  In the binding device 1 according to the fourth embodiment, since the torsion coil spring 311b is connected to the restriction member 301 in the same manner as the binding device 1 of the third embodiment described above, the restriction portion 301 is caused by the biasing force of the torsion coil spring 311b. , Semi-automatically guided to the substrate part 2 side. In addition, unlike the binding device 1 of the third embodiment, the binding device 1 according to the fourth embodiment has the convex portion 50a, so that when the excessive load is applied to the binding device 1 due to the fall of the binder B or the like, the regulation state is reached. Is easily released. That is, when an excessive force is applied in the direction from the regulating member 301 side toward the base member 20f side (the right side in FIG. 20), there is a clearance between the shaft pin 311a and the bearing into which the shaft pin 311a is inserted. The free end of the regulating member 301 contacts the slope 52a1. The free end of the contacting regulating member 301 moves upward along the inclined surface 52a1, and the restricted state is released (see FIGS. 20A to 20C).

As described above, according to the binding device 1 of the fourth embodiment, the spring hinge 311 is provided, so that the regulating member 301 is guided to the regulated state semi-automatically, and the work of attaching the substrate unit 2 to the cover body B is facilitated. Moreover, by providing the convex part 50a, when an excessive load is applied to the binding device 1 due to the fall of the binder B or the like, the restricted state is easily released, and the binding device 1 can be prevented from being damaged by the load.
