Description

  The present invention relates to a binding tool for binding paper sheets and a file including the binding tool.

  Conventionally, various binding tools capable of binding a paper sheet in which a binding foot is inserted into a binding hole by sandwiching the binding foot into a cover body and a file including the binding tool have been proposed ( For example, see Patent Document 1). Particularly in recent years, there has been proposed a device in which the shape and structure of the presser are devised so that the operation for binding can be performed by a simpler operation with fingers (for example, see Patent Document 2).

  The binding tool described in Patent Document 2 described above includes a base including a plurality of binding foot insertion portions for inserting a plurality of binding feet, and a base that is operatively attached to the base and binds the binding feet. A plurality of pressers that can be pressed from the upper side of the foot insertion portion, and the binding portion is positioned at a position where the front end side of the binding foot can be bent along the base, between the plurality of pressers. By simply picking up the operation unit interposed between the finger and the finger, each presser retreats from the upper side of the binding foot insertion portion, whereby the binding between the binding foot and the binding tool is released. Such an apparatus has been widely accepted in offices so far as it can easily and repeatedly perform the binding and adding operations of paper sheets in a file.

  However, even when the binding tool described in Patent Document 2 is operated from the release position to the binding position, the pressing tool still slides along the base and only abuts and bends the binding leg from the lateral direction. Since the operation force is still required, the current situation is that the operation force is required from the release posture to the binding posture as in the conventional binding tool.

  The present invention pays attention to the above-described points, and provides a binding tool that can operate the pressing tool with a smaller operation force when operating the pressing tool to a binding state in which the binding foot is bent. It is aimed.

  In order to achieve such an object, the present invention takes the following measures.

  That is, the binding tool according to the present invention includes a base including a binding foot insertion portion for inserting a binding foot that can be inserted into a binding hole provided in an object in the thickness direction, and a surface direction with respect to the base. Operatively attached and operable between a binding position where the leading end side of the binding foot can be bent along the base on the upper side of the binding foot insertion portion and a retraction position where the binding foot is retracted from the upper side of the binding foot insertion portion. A binding tool including a pressing tool, wherein the base holds the pressing tool above the binding position, and the pressing tool extends from the retracted position to the binding position. The binding foot includes a guide portion that guides the binding foot so as to start contacting the binding foot at a position higher than the binding position. The file according to the present invention is characterized in that such a binding tool is attached to a cover body.

  In such a case, the pressing operation for the binding foot is started at a position where the pressing tool is higher than the binding position. For this reason, the binding foot does not bend a narrow range near the point where the base is inserted as a so-called “bending margin” during the binding operation, but the upper holding portion positions the presser on the upper side. It will be bent at a longer “bend allowance” according to what is done. Thereby, even if the operation force with respect to the pressing tool is small, the binding leg is smoothly bent. As a result, it is possible to provide a binding tool that can bind an object with a smaller operating force.

  In order to configure the upper holding portion and the guide portion with a simple configuration, it is preferable that the base is slidably attached to the base.

  Further, in order to set the presser to the binding position with a smaller operating force, the upper holding portion has a raised surface raised above the binding position in the base, and the guide portion extends from the raised surface. It is desirable to have an inclined surface that faces in a direction inclined downward. By this inclined surface, in addition to the operation force in the surface direction, the operation force in the thickness direction is converted into the operation force in the surface direction, and a smoother operation is promoted.

  In order to prevent the pressing tool from unexpectedly moving from the retracted position and to ensure a comfortable operation, it is desirable to provide the raised surface along the surface direction.

  The file according to the present invention includes a front cover and a back cover that can cover the object to be bound by the binding tool in a plan view, and a back part interposed between the front cover and the back cover. The binding tool is attached to one of the front cover and the back cover, and the other can be continuously provided on the front end side of the binding foot, and can be inserted into the binding hole of the target to hold the target. An auxiliary binding tool having auxiliary binding feet is attached. As a result, when binding a plurality of paper sheets as an object, if a new paper sheet is to be bound between the plurality of paper sheets, a required part of the auxiliary binding legs is required. If the paper sheets are temporarily bound, after binding new paper sheets, it is easy to re-close the required paper sheets by connecting the auxiliary binding legs and the binding legs. obtain. Here, the “back” is formed not only by a mode of interposing as a back cover so as to form a constant thickness dimension between the front cover and the back cover, but also by folding between adjacent front and back covers. It is a concept that includes the edge portion.

  Further, in order to be able to store a file and an unused file in a compact manner, the binding tool and the auxiliary binding tool are respectively attached to symmetrical positions via the back, and the front cover is attached. In addition, it is desirable that a folding engagement portion that can engage the binding tool and the auxiliary binding tool in a folded state in which the back cover is stacked is provided.

  As a specific configuration for accommodating the file in a more compact manner, a configuration in which a central fold line is formed at an intermediate position with respect to the front cover and the back cover in the back portion can be given.

  According to the present invention, it is possible to provide a binding tool that can bind an object with a smaller operating force.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

  As shown in FIGS. 1 to 3, the file F according to the present embodiment can preferably bind a plurality of paper sheets that are objects in an office or home, for example, directly or directly to the cover body H. Indirectly, the fixing tool 5, the binding leg 4, the binding tool 1, and the auxiliary binding tool 6 are attached.

  The front cover body H has a front cover H1 and a back cover H2 that can cover paper sheets that are objects bound to the binding tool 1, and a back part H3 interposed between the front cover H1 and the back cover H2. The binding tool 1 is attached to the back cover H2 through the fixing tool 5 and the binding foot 4, and the auxiliary binding tool 6 is attached to the binding tool 1 through the back H3 at a symmetrical position. Yes. In the present embodiment, a center fold line H4 is formed at an intermediate position of the back portion H3 with respect to the front cover H1 and the back cover H2.

  As shown in FIG. 3, the fixture 5 is formed by, for example, pressing a single sheet metal material, and includes a plate-like body 51 that forms the main body of the fixture 5, and the plate-like body 51. There are binding foot fixing portions 52 to which the base ends of the binding feet 4 are attached at two places.

  In the present embodiment, a binding foot 4 having a tubular shape is applied. Specifically, a metal coil spring-like binding foot 4 is formed, and an opening end 41 communicating to the proximal end side is formed at the distal end.

  The auxiliary binding tool 6 is for suitably performing the adding and removing operation of the paper sheets bound to the binding tool 1. The auxiliary binding tool 6 includes an auxiliary binding leg 7 and an auxiliary fixing tool 8. The auxiliary binding foot 7 is formed by, for example, bending a metal wire rod into a substantially U-shape. In the present embodiment, the auxiliary binding foot 7 is configured to be continuously provided at the front end side of the binding foot 4 so as to be inserted into the binding hole of the paper sheet as the object and hold the paper sheet. It becomes. Specifically, the auxiliary binding foot 7 includes an insertion rod 71 whose both end portions can be accommodated in the binding foot 4 by inserting the insertion end 73 from the opening end 41 of the binding foot 4, and the insertion rod 71. It has the connecting rod 72 to connect. At the center of the connecting rod 72, there is provided a friction bending portion 74 in which the wire is bent in a partial arc shape. The auxiliary fixture 8 is made of a resin fixed to the front cover H1 through, for example, a rivet, and has two bearings 81 that support the connecting rod 72, and a resin at the center of these bearings 81. It has a friction surface 82 that is slightly recessed and molded. That is, when the auxiliary binding foot 7 is rotated and the friction bending portion 74 is in contact with the friction surface 82 of the auxiliary fixing tool 8, the auxiliary binding foot 7 is erected at an angle so that the insertion rod of the auxiliary binding foot 7 can be easily inserted into the binding foot 4. Positioning is performed. In addition to the bearing 81 and the friction surface 82, the auxiliary fixture 8 has an engaging convex portion 83 that can engage with the binding tool 1. The engaging convex portion 83 has engaging claws 84 at both ends in the longitudinal direction. The engaging convex portion 83 will be described later.

  As shown in FIG. 3, the file F according to the present embodiment includes the auxiliary fastener 7 from the fixture 5 by inserting the auxiliary binding foot 7 at the tip of the binding foot 4 with the binding tool 1 removed from the binding foot 4. In this state, the required paper sheets can be moved to the front end side and the connection between the binding legs 4 and the auxiliary binding legs 7 is released. Can be temporarily held on the auxiliary binding leg 7 side. Accordingly, it is possible to easily perform a paper sheet addition / removal operation such as taking out only a paper sheet at an arbitrary position from a plurality of bound paper sheets or replacing the paper sheets in an arbitrary order.

  The binding tool 1 includes a base 2 including a binding foot insertion portion 21 for inserting a binding foot 4 that can be inserted into a binding hole provided in an object in a thickness direction, and a surface direction with respect to the base 2. A binding position (Q) where the front end side of the binding foot 4 is bent and tightened along the base 2 on the upper side of the binding foot insertion portion 21 that is operatively attached, and a retraction that is retracted from the upper side of the binding foot insertion portion 21. It has the pressing tool 3 which can operate | move between positions (P).

  Therefore, the binding tool 1 according to the present embodiment holds the base 2 on the upper side so that paper sheets can be bound by easily operating the pressing tool 3 to the binding position (Q) even with a small operating force. It has the part 22 and the guide part 23, It is characterized by the above-mentioned.

  Hereinafter, a specific configuration of the binding tool 1 according to the present embodiment will be described.

  The base 2 is, for example, a resin molded product in which the presser 3 is slidably attached. The base 2 includes a binding foot insertion portion 21 for inserting a binding foot 4 that can be inserted into a binding hole provided in a paper sheet as an object in the thickness direction, and above the binding position (Q). The upper holding part 22 for holding the pressing tool 3 and the pressing tool 3 at a position higher than the binding position (Q) on the binding foot 4 from the retracted position (P) to the binding position (Q). With respect to the guide portion 23 that guides the binding foot 4 so as to start to contact, the accommodation groove 29 that accommodates the front end portion of the binding foot 4 at the binding position (Q), and the auxiliary fixing tool 8 of the auxiliary binding tool 6 described above. And an engaging recess 24 that can be engaged with each other. The upper holding part 22 is provided with a raised surface 25 that is formed by increasing the thickness of the resin so that the presser 3 can be held on the upper side farther from the paper sheet than the binding position (Q) in the retracted position (P). have. In this embodiment, the raised surface 25 forms a raised point 25 a that is the highest raised portion adjacent to the guide portion 23. This raised point 25a makes point contact with the base 2 when the presser 3 starts to slide toward the binding position (Q). The guide portion 23 includes an upward surface portion 26 that comes into contact with the presser 3 from below, and a flange-like rail portion 27 that protrudes in a short direction to prevent the presser 3 from separating upward. Have. The upward surface portion 26 has an upward inclined surface 26 a continuous with the raised surface 25. In addition to the upper flat surface 27b that engages with the presser 3 at the retracted position (P) and the lower flat surface 27c that engages with the presser 3 at the binding position (Q), the rail portion 27 includes the upper flat surface 27b and the lower flat surface 27b. The rail side inclined surface 27a which is an inclined surface interposed between the side flat surface 27c and the side flat surface 27c is provided.

  The presser 3 is provided so as to be slidable in the longitudinal direction of the base 2. In the present embodiment, two pressers 3 are attached to one base 2 in accordance with the number of binding feet 4 and binding foot insertion portions 21. The presser 3 is formed symmetrically in this embodiment, and includes an operation surface 31 that receives an operation force by the user on the upper side, and a press surface 32 that can directly press the binding foot 4 on the back side of the operation surface 31. In connection with the contact surface 33 that can contact the binding foot 4 prior to the pressing surface 32 at the time of operation at the end surface in the longitudinal direction of the base 2 and the rail portion 27 provided on the base 2, removal from the base 2 is prohibited. And a sliding surface 34. The sliding surface 34 is formed with an inclined surface 34a in which both ends are notched in the inclined direction.

  Therefore, the binding tool 1 according to the present embodiment is provided with the upper holding part 22 and the guide part 23 described above, thereby operating force when the presser 3 is operated from the retracted position (P) to the binding position (Q). Even if it is small, it is configured so that it can be operated smoothly. Hereinafter, the operation of the binding tool 1 will be described with reference to FIGS. In the figure, for the sake of convenience of explanation, it is assumed that the presser 3 shows a central cross section.

  As shown in FIG. 6, when the pressing tool 3 in the retracted position (P) is slid while being pressed from above with fingers or the like, first, the contact surface 33 contacts the binding foot 4. At this time, since the presser 3 is placed on the raised surface 25 at the retracted position (P), more specifically, on the raised point 25a, the contact surface 33 is in the binding position (Q). It starts to contact the binding foot 4 at a higher position than at a certain time. At this time, the presser 3 presses the two points of the raised point 25 a and the binding foot 4. When the presser 3 is slid as shown in FIGS. 7 and 8, the binding foot 4 has a fixed dimension between the binding foot insertion portion 21 and the contact surface 33 as well as the portion that contacts the contact surface 33. The portion to be formed is bent and further received in the receiving groove 29 while being pressed by the pressing surface 32. At this time, the pressing surface 32 slides on the upward inclined surface 26a while pressing the binding foot 4, and the sliding surface 34 slides while the inclined surface 34a abuts on the rail-side inclined surface 27a. As a result, the operation force applied to the operation surface 31 is also converted into a force in the sliding direction. At the same time, the holding tool 3 is moved to a lower position by the guidance by the contact between the rail-side sliding surface 27a and the inclined surface 34a, so that the binding leg 4 can be bent smoothly. Therefore, as shown in FIG. 9, when the presser 3 is moved to the end of the operation, the presser 3 presses the binding foot 4 more strongly on the binding foot insertion portion 21, and the leading end side of the binding foot 4 becomes the substantially accommodating groove 29. The accommodated binding position (Q) is taken. On the other hand, when changing the posture from the binding position (Q) to the retracted position (P) by moving the pressing tool 3 in the opposite direction, the pressing tool 3 is operated in the opposite direction. Is shifted to the raised surface 25 through the upward inclined surface 26a.

  On the other hand, the file F according to the present embodiment takes a compact folded state (R) as shown in the figure when the front cover H1 and the back cover H2 are overlaid as shown in FIG. The state can be maintained stably. For this purpose, the file F according to the present embodiment is folded as shown in FIG. 12 when the front cover H1 and the back cover H2 are overlaid as schematically shown in FIGS. A folding engagement portion X that can engage the binding tool 1 and the auxiliary binding tool 6 in the state (R) is provided. More specifically, the folding engagement portion X includes an engagement convex portion 83 provided on the auxiliary fixture 8 and an engagement concave portion 24 provided on the base 2. The positioning of the base 2 and the auxiliary fixture 8 is realized by the engaging claws 84 positioned being engaged with the engaging surface 28 provided in the engaging recess 24 of the base 2. In the figure, for the sake of convenience, the binding tool 1 side shows a central section, and the binding legs 4 are not shown. Further, if the file F according to the present embodiment is folded at a position of a center fold line H4 where the back portion H3 can be folded at an intermediate position with respect to the front cover H1 and the back cover H2 in the back portion H3, FIG. As shown, accurate engagement between the base 2 and the auxiliary fixing tool 8 can be made compatible with the front cover H1 and the back cover H2 being close to each other and maintaining the cover body H in a compact posture.

  With the configuration described above, the binding tool 1 according to the present embodiment allows the binding foot 4 to perform a so-called “bend allowance” in a narrow range near the portion where the base 2 is inserted as in the conventional case during the binding operation. Rather than being bent as “between”, the upper holding portion 22 bends with a longer “bending allowance” according to the positioning of the presser 3 on the upper side, thereby binding smoothly even if the operating force on the presser 3 is small. The bending motion of the foot 4 is prompted. As a result, the binding tool 1 that can bind the target paper sheet with a smaller operating force is realized.

  Further, in order to configure the upper holding portion 22 and the guide portion 23 with a simple configuration, in the present embodiment, the base 2 is slidably attached to the presser 3.

  In addition, in the present embodiment, the upper holding portion 22 is raised above the binding position (Q) in the base 2 in order to set the presser 3 to the binding position (Q) with a smaller operating force. It has a surface 25, and the guide portion 23 has an upward inclined surface 26a and a rail-side inclined surface 27a which are inclined surfaces inclined downward from the raised surface 25. By the upward inclined surface 26a and the rail-side inclined surface 27a, in addition to the operation force in the surface direction, the operation force in the thickness direction is converted into the operation force in the surface direction, and a smoother operation is promoted.

  Further, in order to prevent the pressing tool 3 from moving unexpectedly from the retracted position (P) and to ensure a comfortable operation, the raised surface 25 is provided flat along the surface direction without being inclined. Yes.

  The file F according to the present embodiment attaches the auxiliary binding tool 6 so that when a plurality of sheets are bound as an object, a new sheet is bound between the plurality of sheets. In such a case, if a part of the required paper sheets are temporarily bound to the auxiliary binding legs 7, after the new paper sheets are bound, the auxiliary binding legs 7 and the binding legs 4 are communicated with each other. Thus, it is possible to easily bind the required paper sheets again.

  In particular, the file F according to the present embodiment is symmetric with respect to the binding tool 1 and the auxiliary binding tool 6 via the back H3 so that the file F can be stored in a compact manner and can be stored in a compact manner. And a folding engagement portion X that can engage the binding tool 1 and the auxiliary binding tool 6 in a folded state (R) in which the front cover H1 and the back cover H2 are overlaid. .

  Furthermore, in this embodiment, in order to accommodate the file F more compactly, a central fold line H4 is formed at an intermediate position with respect to the front cover H1 and the back cover H2 in the back portion H3, and when the folding engagement portion X is engaged. The thickness dimension of the file F can be reduced.
