Description

  The present invention relates to a binding tool for binding a paper sheet or the like, which includes a flexible binding leg provided on a cover of a file and a pressing tool that holds the binding leg.

  2. Description of the Related Art Generally, a binding tool for fixing a flexible binding foot with a pressing tool is widely used. For example, in a binding tool using a thread-like binding leg, the binding leg stands upright, so that it is easy to insert and remove a paper sheet into and from the binding leg. However, the thread-like binding legs are not easily fixed to the pressing tool, and the binding of the paper sheets is easy to loosen.

Therefore, a technique for fixing the binding foot by engaging the binding foot and the tooth-shaped portion when holding the screw-shaped binding foot with a pressing tool is disclosed (for example, see Patent Document 1). In this technique, as shown in FIGS. 10 and 11, the file 166 has a binding body 168 attached to the cover, and the binding body 168 is provided with screw-like tubes 170 and 172. The pusher 174 has binding holes 176 and 178 for inserting the screw-like tube bodies 170 and 172. Stop pieces 180 and 182 and a tooth-shaped portion 184 for fixing the screw-like tube bodies 170 and 172 are provided. 186 is provided. The screw-like tubular bodies 170 and 172 are sandwiched and fixed between the stopper pieces 180 and 182 and the tooth-shaped portions 184 and 186.

  When the threaded binding foot is clamped with a pressing tool, if the binding foot and the tooth-shaped portion are engaged to fix the binding foot, it is still difficult to say that the paper sheet is sufficiently fixed. There is a risk that the binding foot will be loosened during browsing or due to the load of the paper sheet, and appropriate paper sheet filing will not be performed.

  Moreover, in order to increase the fixing force of the binding foot, for example, if the gap between the stopper piece and the tooth-shaped portion is narrowed so that the force of the pressing tool acts strongly, the operability of the binding tool is deteriorated, The binding leg becomes fragile.

  In view of the above-described problems, the present invention has an object to provide a binding tool in which the binding foot is more reliably fixed and has good operability even during binding.

A binding tool according to the present invention has a base member having a long groove extending in a predetermined direction, a through hole provided in the long groove, and a through hole provided in the long groove, and is inserted into the base member and has flexibility. When the binding foot is slid on the base member in a predetermined direction and the binding foot is clamped in the long groove according to the slide position, and the binding foot is clamped in the long groove by the slide member, And holding means for holding the binding foot in the long groove in a state of being held in the long groove by increasing the frictional force between the binding foot and the long groove by meandering the binding foot.

The holding means includes an extruded portion having a shape extruded into the long groove by sliding of the slide member, and a recessed portion facing the extruded portion, and the extruded portion is sandwiched in the long groove by the slide of the slide member. The binding leg may be meandered in the long groove by pushing the binding leg into the recess, and at least one of the pushing part and the recess may be in contact with the binding leg in this state.

Further, the long groove has two side wall portions facing each other, and the holding means is pushed out to the inside of the long groove by sliding of the slide member. And a slide member that slides on the base member to hold the binding foot in the long groove and to be held in the long groove by the push portion. A portion corresponding to the push-out portion of the bound binding foot is pushed into the indentation portion, and the state in which the binding foot is held in the long groove by increasing the frictional force between at least one of the extruding portion and the indentation portion and the binding foot is maintained. It may be made.
At least one of the extruded portion and the recessed portion may have a corner portion.

The binding leg may have a screw-like structure.
Further, the binding leg may be made of metal, and the long groove, the extruded portion, and the recessed portion may be made of resin .

  It is possible to provide a binding tool in which the binding feet are more securely fixed and the operability is good even during binding.

  Here, embodiments of a binding tool and a filing tool according to the present invention will be described with reference to the drawings.

  FIG. 1 is a perspective view showing an open state of the binding tool 1 according to the present invention, and FIG. 2 is a view showing a fixed state of the binding tool 1. Here, the open state refers to a state in which a paper sheet or the like is not bound by the binding tool 1, and the fixed state refers to a state in which the paper sheet or the like can be bound by the binding tool 1. .

The binding tool 1 includes an elongated base member 2 and a slide member 3 slidably mounted on the base member 2. The base member 2 and the slide member 3 are formed of a resin such as polypropylene.

  Here, the base member 2 is provided with a long groove 4 extending along the longitudinal direction thereof. The long groove 4 has side portions 4a and 4b that form side surfaces on both sides thereof, and a bottom portion 4c that forms the bottom surface thereof. Further, in the long groove 4, two through-holes 5 that penetrate the back surface and the front surface of the base member 2 are provided in a portion about 1/3 of the length from both ends thereof. The through hole 5 is also opened on the side portion 4a side of the long groove 4 (refer to FIG. 4 described later for the state of opening of the through hole 5). Incidentally, the through hole 5 is not opened on the side 4b side of the long groove 4.

Next, as shown in FIG. 3, two binding feet 7 are provided on the cover of the filing tool. These binding feet 7 are made of metal such as iron and are coiled springs. The interval between the two binding feet 7 is the same as the interval between the two through holes 5 provided in the long groove 4. The binding foot 7 is in an upright state with respect to the cover, and since it is a metal spring, even if an external force is applied, it has the flexibility to return to its original state as soon as the external force is removed. ing.

  A paper sheet having two holes is inserted into the binding leg 7, and the binding leg 7 is inserted into each of the through holes 5 of the binding tool 1. At this time, the base member 2 and the slide member 3 are in the open state shown in FIG. When the slide member 3 slides in the extending direction of the long groove 4 from that state, the binding foot 7 is gradually drawn into the long groove 4, and finally the binding foot 7 is moved by the base member 2 and the slide member 3 in the long groove 7. (This state is a fixed state shown in FIG. 2). As a result, the paper sheet inserted into the binding foot 7 is filed. Below, while explaining the detailed structure of the base member 2 and the slide member 3, the binding of the paper sheet by said binding tool 1 is demonstrated still in detail.

  FIG. 4 shows a detailed structure of the base member 2. 4 (a) is a front view of the base member 2, FIG. 4 (b) is a rear view thereof, and FIG. 4 (c) is a sectional view thereof (a cross-sectional view taken along the line AA in FIG. 4 (a)). 4 (d) is a side view thereof. The perspective views shown in FIGS. 1 and 2 are views in which the front of the base member 2 shown in FIG.

  As shown in FIG. 4A, a long groove 4 in which the binding foot 7 is accommodated according to the slide of the slide member 3 is provided on the upper surface of the base member 2. A pair of L-shaped arms 8 and raised portions 9a and 9b are provided in the vicinity of each of the through holes 5 opened to the side portion 4a. The L-shaped arm 8 has an L-shaped end portion 8 a (hereinafter referred to as “connection end”) connected to the side wall 4 a side and the other end facing the free groove 8 b in a state facing the long groove 4. It has become. Furthermore, the corner 8c of the L-shaped arm 8 is in a state of slightly protruding outward from the outer wall surface of the side wall 4a. Accordingly, when an external force is applied from the outside to the inside of the long groove 4 with respect to the corner portion 8c of the L-shaped arm 8, the L-shaped arm 8 rotates in the direction of the long groove 4 about the connection end 8a of the L-shaped arm. Then, the free end 8b protrudes into the long groove 4.

  Further, on the side 4 b side of the free end 8 b of the L-shaped arm 8, two raised portions 9 a and 9 b that are raised in the long groove 4 are provided. More specifically, the free end 8b of the L-shaped arm 8 is located on the side portion 4a side that faces the substantially middle position between the raised portion 9a and the raised portion 9b. Accordingly, the long groove 4 extending in the longitudinal direction of the base member 2 has a slightly meandering shape due to the raised portions 9a and 9b.

Next, as shown in FIG. 4 (b), on the back surface of the base member 2, when the slide member 3 is engaged with the base member 2 as shown in FIGS. A total of four sliding grooves 10 for sliding the portion 15 (see FIG. 5 described later) are provided on the left and right sides of the side portion 4a and the side portion 4b. In the slide groove 10, when the slide member 3 is positioned at the end on the left side as viewed in FIG. 4, the open state shown in FIG. 2 is the fixed state shown in FIG.

  Further, in the slide groove 10 on the side portion 4b side, a protrusion 11 that slightly protrudes into the slide groove 10 is provided near the left end. Thus, as shown in FIGS. 1 and 2, when the slide member 3 is engaged with the base member 2, the movement of the slide portion 15 of the slide member 3 is slightly disturbed by the projection 11. Therefore, when the base member 2 and the slide member 3 are in the open state shown in FIG. 1, this open state is maintained by the protrusion 11. Of course, since a slightly large external force is applied to the slide member 3, the slide member 3 easily gets over the projection 11, so that the slide operation of the slide member 3 is not significantly difficult by the projection 11.

  FIG. 4C shows a cross section in the vicinity of the L-shaped arm 8 described above. FIG. 4D shows a side surface of the base member 2 on the side portion 4b side.

  Next, FIG. 5 shows a detailed structure of the slide member 3. 5 (a) is a front view of the slide member 3, FIG. 5 (b) is a side view thereof, FIG. 5 (c) is a rear view thereof, and FIG. 5 (d) is a sectional view thereof (FIG. 5). 5 (b) is a cross-sectional view taken along the line CC in FIG. 5 (b), and FIG. 5 (e) is a cross-sectional view thereof (a cross-sectional view taken along the line BB in FIG. 5 (a)). In addition, the perspective view shown to FIG. 1, FIG. 2 is a figure which can mainly see the front of the slide member 3 shown to Fig.5 (a).

  As shown in FIG. 5A, the slide member 3 has a shape in which two pressing portions 12 are connected by a connecting portion 13. The connecting portion 13 connects the one end portions of the two pressing portions 12. 5 (e) is a cross-sectional view taken along the line BB in the pressing portion 12. As shown in FIG. 5, the pressing portion 12 includes two side surfaces 12a, a back surface 12b connecting them, and a slide portion described later. 15

  As shown in FIG. 1 or 2, the pressing portion 12 applies an external force with a finger or the like so that the slide member 3 slides on the base member 2 in a state where the base member 2 and the slide member 3 are combined. It is a part. Therefore, on the pressing portion 12, a plurality of protruding portions 14 having a concavo-convex shape with a continuous surface as shown in FIG. 5B are provided so that an external force is easily transmitted easily with a finger or the like. ing.

  Further, as shown in FIG. 5C, slide portions 15 that slide relative to the slide grooves 10 of the base member 2 are provided at the four corners of each pressing portion 12. That is, the four slide portions 15 included in the two pressing portions 12 are relatively slid in correspondence with the slide grooves 10 included in the base member 2. Further, when the slide member 3 slides on the base member 2, the slide portion 15 comes into contact with both end portions of the slide groove 10, and the slide of the slide member 3 is restricted. Thereby, it becomes possible to prevent the slide member 3 from being easily detached from the base member 2.

  Further, as shown in FIGS. 5 (d) and 5 (e), the surface of the back surface 12 b that is in contact with the base member 2 when the slide member 3 is combined with the base member 2 is not slid. Two elongated ridges 16 extending in the longitudinal direction of the member 3 are provided. The ridge 16 forms a recess 17 extending in the longitudinal direction of the slide member 3 therebetween. The distance between the two raised portions 16 is about the same as the width of the long groove 4 described above. That is, the binding foot 7 accommodated in the long groove 4 according to the slide of the slide member 3 is held between the long groove 4 and the recess 17 of the slide member 3.

  Here, the base member 2 shown in FIG. 4 and the slide member 3 shown in FIG. 5 are combined so that the slide groove 10 and the slide portion 15 slide relative to each other, whereby the binding shown in FIG. The insert 1 is formed. Here, the state where the binding foot 7 is clamped when the slide member 3 is slid from the opened state shown in FIG. 1 to the fixed state will be described with reference to FIG.

  FIG. 6 shows a state in which the binding foot 7 is sandwiched between the base member 2 and the slide member 3 in the long groove 4 by sliding the slide member 3 into the fixed state. As described above, in this fixed state, the slide member 3 pushes the corner portion 8c of the L-shaped arm into the long groove 4 side. As a result, the free end 8 b of the L-shaped arm 8 comes into contact with the binding foot 7 accommodated in the long groove 4. The binding foot 7 pushed by the free end 8 is bent in a convex state toward the side portion 4b. At this time, the raised portions 9a and 9b are provided on the left and right sides of the free end 8b. Is bent while in contact with the raised portions 9a, 9b and the free end 8b.

  Therefore, when the slide member 3 is in a fixed state as shown in FIG. 6, the binding foot 7 comes into contact with the end of the free end 8b and the end of the raised portions 9a, 9b. Large stress will act. As a result, the frictional force when the binding foot 7 is sandwiched between the base member 2 and the slide member 3 becomes relatively large, and the binding foot 7 can be fixed more reliably.

  Furthermore, since the binding foot 7 is a coiled spring as described above, the end of the free end 8b and the ends of the raised portions 9a and 9b may be sandwiched between the spring lines. In particular, in the region surrounded by the dotted line in FIG. 6, the spring is easily caught. When the pinching of the spring occurs in this way, a force for fixing the binding foot 7 more strongly is generated separately from the frictional force described above. Further, when the slide member 3 in the fixed state shifts to the open state, the force applied to the binding foot 7 is weakened, so that the pinching of these springs is eliminated.

  Here, FIG. 7 shows a plurality of specific examples of the structure of the base member 2 sandwiched in the long groove 4 in a state where the binding foot 7 is bent. FIG. 7A shows the same structure as that of the base member 2 described above. Instead of the base member 2, a base member 20 shown in FIG. 7B is also useful. The base member 20 is characterized in that the shape of the L-shaped arm 28 is opposite to that of the L-shaped arm 8 shown in FIG. When the slide member 3 shifts to the fixed state, it comes into contact with the free end 28b of the L-shaped arm 28. As a result, the L-shaped arm 28 rotates around the connecting end 28a and its corner 28c protrudes toward the long groove 4 side. To do. Thereby, the binding leg 7 accommodated in the long groove 4 is held in the long groove 4 while being bent by the raised portions 9a and 9b and the corner portions 28c.

  Moreover, it replaces with the base member 2 shown to Fig.7 (a), and the base member 30 shown to FIG.7 (c) is also useful. The base member 30 is characterized in that a T-shaped arm 38 is provided. The T-shaped arm 38 includes two free ends 38b and 38c in addition to the connection end 38a connected to the side portion 4a. One free end 38b is a free end on the side opposite to the long groove 4, and its end surface protrudes slightly outward from the outer wall surface of the side portion 4a. The other free end 38c is a free end on the long groove 4 side. Therefore, when the slide member 3 shifts to the fixed state, it comes into contact with the free end 38b of the T-shaped arm 38. As a result, the T-shaped arm 38 rotates about the connecting end 38a and the free end 38c moves to the long groove 4 side. Protruding. Thereby, the binding leg 7 accommodated in the long groove 4 is held in the long groove 4 while being bent by the raised portions 9a, 9b and the free end 38c.

Furthermore, instead of the base member 2 shown in FIG. 7A, a base member 40 shown in FIG. 7D is also useful. The feature of this base member 40 is that the L-shaped arm 8 on the side portion 4b is opposed to
The depression 41 is provided. That is, the base member 40 is provided with a recessed portion 41 that is slightly recessed in the wall from the wall surface of the side wall, instead of the raised portions 9a and 9b shown in FIG. By using such a base member 40, when the slide member 3 shifts to a fixed state, it comes into contact with the corner portion 8c of the L-shaped arm 8, and as a result, the L-shaped arm 8 rotates around the connection end 8a. And the free end 8b protrudes to the long groove 4 side. Thereby, the binding leg 7 accommodated in the long groove 4 is held in the long groove 4 while being bent by the depressed portion 41 and the free end 8b.

  Here, FIG. 8 shows a filing tool 50 using the binding tool 1 described above. The filing tool 50 includes a front cover 51, a back cover 52, a binding margin 53, and a back cover 54 formed by bending one sheet of polypropylene, and a hinge is formed at the boundary. Then, two holes for the binding legs 7 are formed on one side of the binding margin 53, and after the binding legs 7 are inserted into the holes, the binding margin 53 is fixed by ultrasonic welding.

  Here, the binding foot 7 is a coiled spring as described above. The diameter of this coil is larger than the diameter of the hole. Therefore, when the binding foot 7 is inserted into the hole, it is inserted along the coil line. For this reason, it is possible to avoid the binding foot 7 from being detached from the hole provided in the binding margin 53. Further, the diameter of many regions of the coil may be smaller than the diameter of the hole, and the diameter of a part of the coil may be larger than the diameter of the hole. Thereby, it becomes possible to prevent the binding foot 7 from being detached from the hole.

  A second embodiment of the binding tool according to the present invention is shown in FIG. The binding tool according to the present embodiment realizes the function of fixing the binding foot in a bent state in a mode different from the mode illustrated in the first embodiment. The details will be described below, but the same reference numerals are given to the same components as those shown in the first embodiment, and the detailed description thereof will be omitted.

  Fig.9 (a) is the top view which looked at the binding tool which concerns on a present Example from the upper side in the fixed state. FIG. 9B is a cross-sectional view when the binding tool is cut in the longitudinal direction of the base member 2. In the present embodiment, a protrusion 61 is provided on the surface of the slide member 3 and on a portion facing the bottom 4 c of the long groove 4 of the base member 2. Furthermore, two raised portions 62 a and 62 b extending in the width direction of the bottom portion 4 c are provided on the bottom portion 4 c of the long groove 4 of the base member 2. The raised portions 62a and 62b are located at a position where the projection 61 reaches approximately the middle between the raised portions 62a and 62b when the slide member 3 is in the fixed state.

  In the binding tool configured as described above, when the slide member 3 is moved from the open state to the fixed state, the binding foot 7 is moved to the bottom 4c side of the long groove 4 by the protrusion 61 as shown in FIG. It is held in the long groove 4 while being pushed and bent. Accordingly, as in the first embodiment, a relatively large stress acts on the contact portion between the projection 61, the raised portions 62a and 62b, and the binding foot 7. As a result, the frictional force when the binding foot 7 is sandwiched between the base member 2 and the slide member 3 becomes relatively large, and the binding foot 7 can be fixed more reliably. Furthermore, since the binding foot 7 is a coiled spring as described above, when the protrusion 61 and the raised portions 62a and 62b are sandwiched between the springs, the binding foot 7 is made stronger separately from the frictional force described above. A pinching force is generated.

As described above, the binding foot according to the present embodiment has a binding foot in a long groove provided in the base member in a binding tool for binding a paper sheet or the like by sandwiching the binding foot between the base member and the slide member. It was decided to fix in a bent state. By doing so, it is possible to suppress as much as possible that the binding foot moves in the long groove.

Specifically, it is a binding tool for binding paper sheets and the like, and has a base member having a long groove extending in a predetermined direction and a through hole provided in the long groove, and is inserted into the base member and has flexibility. A binding foot, a slide member that slides on the base member in the predetermined direction and clamps the binding foot in the long groove according to the slide position, and the binding foot is moved into the long groove by sliding the slide member. And holding means for holding the binding foot in the long groove in a bent state when sandwiched.

In the binding tool described above, when the slide member slides with the binding foot inserted through the base member through the through hole, the binding foot is sandwiched in the long groove. Then, it is possible to bind a paper sheet or the like through which the binding foot is passed by using a frictional force generated between the binding foot sandwiched and the base member and the slide member.

Here, the predetermined direction in which the long groove provided in the base member extends is a direction in which the binding foot can be sufficiently stored therein, and the binding foot is gradually moved into the long groove by sliding the slide member in the predetermined direction. Then, the binding legs are held between the base member and the slide member. Therefore, the long groove may extend in any direction as long as the volume can store the binding foot, and is determined in consideration of convenience as a binding tool.

In the binding tool, when the binding foot is closed by the base member and the slide member, the binding foot is held by the holding means. If the binding means is held in a state where the binding leg is bent in the long groove by the holding means, the binding leg described above may be used for the reason that stress acts intensively at the contact portion between the binding leg and the long groove. It becomes possible to increase the friction force generated between the base member and the slide member. As a result, the binding foot is more securely fixed, and the binding foot is less likely to be loosened by the load of the paper sheet when browsing the paper sheet bound to the binding foot. Further, since the binding foot itself is fixed only by the sliding movement of the slider member, the operability at the time of binding is also good.

Here, the holding means may include an extruding part that is pushed out to the inside of the long groove by sliding of the slide member, and a recessed part that is provided at a predetermined portion of the long groove facing the extruding part. Good. That is, when the extrusion portion is extruded, the binding leg having flexibility and the extrusion portion come into contact with each other. And the binding leg which received the contact is received by the hollow part, and the binding leg is hold | maintained in the state bent in the long groove here. As a result, the binding foot can be more securely fixed as described above by the frictional force generated when the binding foot is bent and comes into contact with the extruded portion and the indented portion.

Here, the predetermined part where the indented part is provided is a part facing the pushing part, and means a part where the binding foot that has been contacted by the pushing part described above can be received.

Furthermore, when the long groove has two side wall portions that face each other, the pushing portion is provided on one side wall portion of the two side wall portions, and the indentation portion is the other of the two side wall portions. When the slide member slides on the base member, a part of the slide member may come into contact with the push-out portion and push the push-out portion inside the long groove. By doing in this way, it becomes possible to function effectively the side wall which a long slot opposes as a holding means mentioned above.

Here, the recessed portion may be formed by at least two raised portions that are provided in the long groove at a predetermined interval and are raised in the long groove. Moreover, the said recessed part may be comprised by the depression part formed by the surface further depressed from the position of the wall surface of the said long groove. That is, by providing a raised portion or a depressed portion in the long groove, it is possible to meander the shape of the long groove and hold the flexible binding leg in a bent state by the sliding operation of the slide member.

Further, the following holding means can be applied in place of the above-described aspect of the holding means. That is, when the slide member slides the base member in a state of covering the long groove, the holding means is provided on the wall surface of the slide member facing the bottom surface of the long groove and protrudes with respect to the long groove You may make it have a part and a bottom face recessed part provided in the bottom face of the said long groove.

That is, when the slide member slides, the protrusion comes into contact with the flexible binding leg. And the binding leg which received the contact is received by a bottom face hollow part, and the binding leg is hold | maintained in the state bent in the long groove. As a result, the binding foot can be more securely fixed as described above by the frictional force generated by the binding foot being bent and contacting the protrusion and the bottom recess.

Here, the bottom recess portion may be provided at a predetermined interval on the bottom surface of the long groove, and may be configured by at least two raised portions that protrude from the bottom surface. The bottom recess may be constituted by a recessed portion formed by a surface further recessed from the position of the bottom surface of the long groove. That is, by providing a raised portion or a depressed portion on the bottom surface of the long groove, the shape of the long groove can be meandered, and the flexible binding leg can be held in a bent state by the sliding operation of the slide member.

In the binding tool described above, the binding foot may have a screw-like structure. If it does in this way, when a binding leg is hold | maintained in the state bent by the said holding means, the structure near the bent site | part will be bitten between the lines of a screw-like structure. As a result, in addition to the frictional force described above, the binding foot can be more reliably fixed by this biting. For example, when the concave portion of the holding means is formed by the above-described depressed portion or raised portion, the binding force of the binding foot can be reduced by biting the ridge of the raised portion or the depressed portion between the lines of the spiral structure. Will rise further.

Furthermore, in the binding tool described above, the binding legs may be made of metal, and the base member and the slide member may be made of resin. Since the binding legs are made of metal in this way, when the paper sheets are passed through the binding legs, since the binding legs are firmly upright, it is easy to bind the paper sheets. Moreover, it is possible to form a flexible binding leg by appropriately selecting a metal material. In addition, since the base member and the slide member are made of resin, molding is easy and the manufacturing cost can be reduced, and the elastic action of the resin is used to bind the binding legs without applying excessive weight to the binding legs. Contact between the foot and the slide member or the like can be closely increased, and the fixing force of the binding foot can be further increased.

Here, in the filing tool for filing a paper sheet, including the binding tool having the above-described screw-like structure, the binding foot having the screw-like structure is inserted into a hole provided on a cover forming the filing tool, In addition, the diameter of at least a part of the threaded structure portion of the binding foot is made larger than the diameter of the hole. That is, the diameter of many regions of the screw-like structure portion is made smaller than the diameter of the hole, and the diameter of a part thereof is made larger than the diameter of the hole. Since the binding foot has a screw-like structure, it is possible to insert the binding foot into a hole having a diameter smaller than that of the binding foot along the line of the screw-like structure. And since the diameter of this hole is smaller than the diameter of a binding leg, it becomes possible to suppress that the binding leg connected to the filing tool falls off. Then, by filing the paper sheet with this filing tool, when the paper sheet bound to the binding leg is viewed, the fixing of the binding leg is less likely to be loosened by the load of the paper sheet.
