As shown in FIG. 7, the binding tool 100 includes a presser fitting 110 that holds the document D, and a locking bar 120 that is slidably stacked on the presser fitting 110. A pair of insertion holes 111 through which the binding legs 210 of the binding leg member 200 pass are formed in the presser fitting 110, and the binding legs 210 that protrude through the binding hole D1 of the document D and protrude upward are shown in FIG. As shown in (a), the insertion hole 111 is inserted.
[0003]
On the other hand, the locking rod 120 has a pair of central rods 121 that are connected so as to be able to be bent upwards at the central portion, and a pair of side portions that are connected to the ends of the central rods 121 so as to be bent upwardly. Each side hook 122 is laminated on the presser fitting 110 so as to be slidable without being separated.
[0004]
Accordingly, as shown in FIG. 7 (a), by pressing downward the joint portion of the pair of central rods 121 that are bent and protrudes upward, the side rods 122 are separated from each other on the presser fitting 110. As shown in FIG. 7B, the center rod 121 is in a horizontal posture, and each side rod 122 pushes down the binding leg 210 so as to press and hold it between the presser fittings 110, as shown in FIG. D is in a state of being spelled by the binding tool 100.
[0005]
On the other hand, in order to solve the once-bound document D, in the state shown in FIG. 7B, the connection portion of the pair of central rods 121 may be picked up with a finger and pulled upward. Then, the pair of central rods 121 are inverted V-shaped and project on the presser fitting 110, and the pair of side flanges 122 move in a direction approaching each other on the presser fitting 110, as shown in FIG. In order to return to the state, the lock of the binding leg 210 is released, whereby the document D can be removed from the binding tool 100.
[0006]
[Problems to be solved by the invention]
By the way, in the conventional binding tool 100 as described above, in order to release the pressing of the binding foot 210 pressed by the locking rod 120, the joint portion of the pair of central rods 121 is picked up with a finger and is moved upward. Therefore, it has been difficult to operate.
[0007]
The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a binding device in which a pressing release operation of a binding foot pressed by a locking rod is easy.
[0008]
[Means for Solving the Problems]
The binding tool according to claim 1 is coupled to a long presser fitting having a pair of insertion holes through which the pair of binding legs in the longitudinal direction of the binding foot member are inserted, and to the presser fitting so as to be slidable in the longitudinal direction. A locking rod is provided, and the locking rod is connected to a pair of central rods that can be folded upward and bent at the central portion, and is connected to an end portion of each central rod so as to be folded upward and concave. Each of the side heels slides in the separating direction, and each of the side heels slides away from each other so that the spelling foot protruding from the insertion hole is pressed and clamped between the presser fitting and each side portion. Each of the central rods is configured to be changeable between a release posture in which the pressing pinch is released in a state where each central rod protrudes upward in an inverted V shape by sliding in the proximity direction. On the top surface of the other center ridge Operating piece is attached to the central portion of the guide projection, mounting port for mounting to the latching rod the pressure foot which is formed by opposed edges are cut is provided, the pressing fixture Is provided with a plate-shaped metal fitting main body and a pair of L-shaped guide protrusions formed in a cross-sectional view formed by folding back both sides of the metal fitting main body in the direction facing each other, The side hooks are a pair of guided protrusions extending in the longitudinal direction extending in opposite directions from both side parts of the side hook main body set in an inverted U shape in cross-sectional view. The presser fitting includes a pair of guided ridges fitted between the pair of guide ridges so that the side hooks are guided by the pair of guide ridges. characterized in that it is configured so as to slide on It is intended to.
[0009]
According to this binding tool, in a state in which a pair of binding legs are passed through the binding holes of the document, each binding leg is inserted into the insertion hole of the presser fitting, and each central hook of the locking rod set in the release posture is set. Each side bar is moved in a direction away from each other while pushing down the spell leg protruding upward from the insertion hole while being guided by the presser fitting, and the locking bar is set to the spell posture. By doing so, the binding leg is pressed and clamped between the side heel and the presser fitting, whereby the document is bound by the binding tool.
[0010]
On the contrary, in order to cancel the spelling of the document bound to the binding tool, it is only necessary to pick up the tip of the operation piece with a finger. By doing so, the pair of central rods are bent upward in the connection position and are raised upside down on the presser fitting in an inverted V shape, and the side rods move in directions close to each other, and the locking rods are The posture is changed from the spelling posture to the cancellation posture. And when the locking hook is set to the release posture, the pressing pinching between the side hooks of the binding foot and the presser fitting is canceled, so that the document is in a spelled state by pulling out the binding foot from the insertion hole of the presser fitting. It will be resolved.
[0011]
And since the operation piece is attached to the upper surface of one central rod so as to extend over the upper surface of the other central rod, when changing the position of the locking rod set in the spelling posture to the release posture, Since the distance between the tip of the piece and the bending position of the center rod, that is, the distance between the moment fulcrum and the force point is longer than when there is no operation piece, the central rod can be easily raised. This facilitates the document unwinding operation.
[0012]
According to a second aspect of the present invention, in the binding tool of the first aspect, the operation piece is detachably attached to the central rod.
[0013]
According to this binding tool, by preparing in advance a plurality of types of operation pieces that have been designed in various ways, the operation pieces can be replaced as desired. Further, it is possible to easily make a custom-made one with an operation piece prepared according to a customer's request.
[0014]
DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is an exploded perspective view showing an embodiment of a binding device according to the present invention. FIGS. 2 and 3 are assembled perspective views. FIG. 2 shows a state in which the locking rod is set in the spelling release posture, and FIG. 3 shows a state in which the locking rod is set in the spelling posture. Yes. FIG. 4 is a cross-sectional view taken along line AA in FIG. As shown in these drawings, the binding tool 1 includes a binding foot member 2 attached to the document D (FIGS. 2 and 3), and a presser fitting 3 attached to the binding foot member 2 via the document D. The basic structure is composed of a locking bar 4 slidably stacked on the presser fitting 3.
[0015]
The binding leg member 2 is a flexible member made of synthetic resin, and includes a sandwich plate 21 made of an elongated plate-like body, and a pair of longitudinal legs 22 standing on both sides of the sandwich plate 21. It is made up of. A stop hole 23 is formed in each end of the sandwich plate 21. This stop hole 23 is for fixing the binding leg member 2 to a file cover (not shown) as required. The binding legs 22 are inserted into the binding holes D1 (FIG. 2) of the document D, and a plurality of locking protrusions 22a arranged in a row protrude from the opposite surfaces of the binding legs 22. It is installed.
[0016]
The presser fitting 3 is laminated on the pinching plate 21 of the binding leg member 2 via the document D, and is formed by pressing a metal plate. The presser fitting 3 is an L-shaped guide in a cross-sectional view formed by folding a plate-like metal fitting body 31 longer than the binding leg member 2 and both sides of the metal fitting body 31 in the width direction so as to face each other. The protrusion 32 is provided.
[0017]
A guide groove 33 for guiding the slide of the locking rod 4 is formed between each guide protrusion 32 and the metal fitting body 31. The distance between the edges of the guide protrusions 32 is set slightly larger than the width dimension of the binding leg 22, so that the binding legs 22 can be fitted between the guide protrusions 32.
[0018]
At the center of each guide protrusion 32, there is provided a mounting opening 34 for mounting the locking bar 4 to the presser fitting 3, which is formed by cutting opposite edges. Further, a pair of first locking projections 31 a in the longitudinal direction is provided in the vicinity of the mounting opening 34 of the metal fitting body 31. On the opposing surfaces of these first locking projections 31a, inclined surfaces 31b are formed which are first lowered in the opposing direction.
[0019]
Further, a pair of longitudinal insertion holes 35 through which the above-described binding feet 22 are inserted are formed at positions outward from the first locking projections 31 a of the metal fitting body 31, and the binding feet 22 are respectively inserted into these insertion holes 35. By doing so, the presser fitting 3 is coupled to the binding leg member 2.
[0020]
Further, two small second locking projections 31 c that are juxtaposed in the longitudinal direction are provided on the outer positions of the insertion holes 35 in the metal fitting body 31, respectively. These second locking protrusions 31c are fitted between the locking protrusions 22a of the spell legs 22 bent in opposite directions on the metal fitting body 31, thereby preventing the spell legs 22 from shifting. It is.
[0021]
The locking rod 4 is integrally formed by injection molding a synthetic resin material. The locking rod 4 is detachably attached to the pair of longitudinal center pair 41, the pair of longitudinal side portions 42 connected to the outer end portion of the center rod 41, and one center rod 41. And an operation piece 43. The pair of central rods 41 are connected to the lower ends of the central rods 41 that are opposed in the longitudinal direction so as to be able to bend upward and convex with a central hinge portion 44 (FIG. 2). The upper end portions facing each other are connected to each other by a side hinge portion 45 so as to be able to be bent concavely upward.
[0022]
The hinge portions 44 and 45 are formed integrally with the central rod 41 and the side rod 42 when the locking rod 4 is molded using a predetermined mold, and the thickness is set thinly. Thus, the plastic material can be bent while being elastically deformed by the inherent flexibility of the synthetic resin material, thereby serving as a hinge.
[0023]
The center rod 41 is formed to be slightly narrower than the gap dimension between the guide protrusions 32, and the thickness dimension (the vertical dimension) is set slightly thicker than the vertical dimension of the guide protrusions 32. As a result, the upper part protrudes slightly upward from the guide protrusion 32 and can be fitted between the guide protrusions 32 while sliding on the metal fitting body 31.
[0024]
The side hooks 42 are a pair of side hooks 42a set in an inverted U shape in a cross-sectional view, and a pair of width direction extending in the longitudinal direction projecting in opposite directions from both sides of the side hooks 42a. The guide protrusion 42b and the finger hooking protrusion 42c projecting upward at the end opposite to the side hinge 45 of the side flange main body 42a. The side rod main body 42a is set to have the same width and vertical dimensions as those of the central rod 41, and the length dimension is set slightly shorter than the length dimension of the mounting opening 34 of the presser fitting 3. .
[0025]
The guided protrusion 42b is set to be slightly thinner than the groove width of the guide groove 33 of the presser fitting 3, and the outer dimension between the guided protrusions 42b is such that the pair of guide grooves 33 are mutually connected. The dimension is set slightly shorter than the dimension between the opposed groove bottoms, and the side flanges 42 are guided to the guide groove 33 by fitting the pair of guided protrusions 42 b into the corresponding guide grooves 33 through the mounting openings 34. The bracket body 31 can be slid while being moved.
[0026]
The pair of side ridges 42 are provided with partition walls 42d that block the inverted U-shaped grooves of the side ridges 42 at opposite ends. Therefore, when the side ribs 42 are fitted between the guide ridges 32, when the guided ridges 42b are fitted into the guide grooves 33 from the mounting openings 34, the partition walls 42d interfere with the first locking projections 31a. However, since the inclined surface 31b is provided on the first locking projection 31a, the partition wall 42d is guided by the inclined surface 31b and climbs, and the first locking projection 31a is moved by elastic deformation of the guided protrusion 42b. The side rod 42 is attached between the guide protrusions 32 by spending time.
[0027]
The locking rod 4 in which the pair of central rods 41 and the pair of side rods 42 are connected in series is set to have a length longer than the outer dimension between the second locking protrusions 31c of the presser fitting 3, As a result, the side hooks 42 can cover the second locking protrusions 31 c in a state where the locking bar 4 is attached to the presser fitting 3 and the operation piece 43 is set at the center position of the presser bar 3. It is like that.
[0028]
The operation piece 43 has one side fixed on the top plate 41 a of one central rod 41, and the other side is thus laid on the top plate 41 a of the other central rod 41. . In the present embodiment, the operation piece 43 is set in an elliptical shape in plan view in consideration of design.
[0029]
As shown in FIG. 4, the operation piece 43 has a plate-like operation piece main body 43a attached to the top plate 41a of the central rod 41, and 2 protruded downward on the back side of the operation piece main body 43a. It consists of two press-fitting protrusions 43b. The operation piece main body 43a is set to have the length dimension substantially the same as the length dimension of the central rod 41, and the left half is fixed to the left central rod 41 in FIG. It is in the state which contact | abutted to the top plate 41a of the collar 41. FIG.
[0030]
The press-fitting protrusion 43b is provided on the left half of the operation piece main body 43a. On the top plate 41a of the left central rod 41, a press-fitting hole 41b corresponding to the press-fitting protrusion 43b is formed. Yes. The diameter of the press-fitting hole 41b is set to be slightly smaller than the outer diameter of the press-fitting protrusion 43b. Therefore, by pressing the operation piece main body 43a in the direction of the center rod 41 with the press-fitting protrusion 43b facing the press-fitting hole 41b, the press-fitting hole 41b is expanded in diameter or the press-fitting protrusion 43b is reduced in diameter. However, the press-fitting protrusion 43b is fitted into the press-fitting hole 41b while the diameter of the press-fitting hole 41b and the diameter of the press-fitting protrusion 43b are simultaneously reduced, so that the operation piece 43 is moved to the left. It is fixed to the central rod 41.
[0031]
Therefore, the operation piece 43 can be attached to and detached from the top plate 41a of the center rod 41 by applying a considerable force, and can be easily exchanged for a desired design.
[0032]
FIG. 5 is an explanatory view showing a mounting procedure of the locking rod 4 to the presser fitting 3. FIG. 5A shows a state immediately before the left side hook 42 is inserted into the guide groove 33 of the presser fitting 3. 5B is a state in which the left side flange 42 is being inserted into the guide groove 33, and FIG. 5C is a state immediately before the right side flange 42 is inserted into the guide groove 33. 5 (d) shows a state in which the right side flange 42 is mounted in the guide groove 33. FIG.
[0033]
When mounting the locking bar 4 to the presser fitting 3, first, the left side bar 42 is fitted into the mounting port 34 (FIG. 1) of the presser bar 3 so that the state shown in FIG. Become. In this state, the guide rib 42b (FIG. 1) is fitted into the guide groove 33 of the presser fitting 3 by pressing the left side bar 42 toward the left, whereby the side bar 42 is guided into the guide bar. It will be inserted between the articles 32.
[0034]
Then, in a state where most of the side hooks 42 are fitted between the guide protrusions 32, the partition wall 42d of the side hook 42 interferes with the first locking protrusion 31a on the left side. By pressing strongly toward the left, the lower edge portion of the partition wall 42d is guided by the inclined surface 31b of the first locking projection 31a and climbs the inclination, so that the guided protrusion 42b and the guide protrusion are accordingly adjusted. 32 is elastically deformed to a state as shown in FIG. In this state, by further pressing the side bar 42 toward the left, the partition wall 42d moves over the first locking projection 31a and moves to the left, whereby the left side bar 42 moves the presser fitting 3 It will be in the state where it was attached to.
[0035]
Next, as shown in FIG. 5C, when the right side hook 42 is fitted into the mounting opening 34 and moved rightward, as shown in FIG. 4 is attached to the presser fitting 3. Then, in a state where the locking rod 4 is once attached to the presser fitting 3, that is, each side rod 42 is fitted in the guide groove 33, the central rod 41 is set to the release posture by operating the operation piece 43. Even if the side rods 42 are moved in a direction approaching each other, the partition wall 42d of the side rod 42 abuts against the first locking projection 31a of the metal fitting body 31, so that the side rod 42 is attached to the mounting port 34. The inconvenience of getting out of the door is surely prevented.
[0036]
According to the above configuration of the binding tool 1, the presser fitting 3 in which each of the binding feet 22 of the binding foot member 2 is inserted into the pair of binding holes D1 of the document D, and the center rod 41 is continuously set to the binding release posture. By externally fitting the pair of insertion holes 35 to each binding leg 22, the document D is held between the holding plate 21 and the presser fitting 3 of the binding leg member 2 as shown in FIG. 1.
[0037]
In this state, by pressing the upper end portion of the operation piece 43 downward, the inclination angle of each central rod 41 that is connected by the central hinge portion 44 and rises obliquely is reduced, so that each center The lower ends of the collars 41 move in the separating direction, and thereby a pair of side collars 42 connected to the central collar 41 via the side hinges 45 are guided by the guide grooves 33 while being paired with the pair of binding legs 22. As shown in FIGS. 3 and 4, the document D is in a state of being bound by the binding tool 1 as shown in FIGS. 3 and 4.
[0038]
Conversely, in order to remove the document D bound by the binding tool 1 from the binding tool 1, the operation piece 43 in the state shown in FIGS. 3 and 4 may be picked up with a finger and pulled upward. Then, the pair of central rods 41 set in the spelling posture are pulled upward, and thereby the left and right side rods 42 move in a direction approaching each other on the metal fitting body 31, and are shown in FIG. In this way, the lock of the spelling foot 22 is released. In this state, the spelling state of the document D can be canceled by pulling out the binding leg 22 from the spelling hole D1 of the document D.
[0039]
6A and 6B are explanatory diagrams for explaining the operation of the operation piece 43 according to the present invention, in which FIG. 6A shows a state in which the central collar 41 is set to the spell release posture, and FIG. Each of the states set in the spelling posture is shown. As shown in FIG. 6, in the present invention, the operation piece 43 is fixed so as to hang on one (left side in the figure) central rod 41 and on the other (right side in the drawing) central rod 41. Accordingly, when the posture changes in posture spelling a central rod 41 set in the spelling releasing posture, as shown in (b) of FIG. 6, the top end portion of the operation piece 43 toward the lower side by a force F pressing Therefore, a force point P1 for posture changing operation is formed at the upper end of the operation piece 43, and a fulcrum O is formed at the side hinge 45.
[0040]
Therefore, if the distance between the fulcrum O and the force point P is L1, a moment of L1 × F1 acts on the center rod 41 to change the posture of the center rod 41 to the spelling posture. On the other hand, in the state where the operation piece 43 does not exist as in the prior art, since the upper end portion of the operation piece 43 becomes the force point P2, the horizontal distance between the action point O and the force point P2 is L2, and the force applied to the force point P2 is F2. As a result, the moment acting on the central rod 41 is L2 × F2. Since the same moment is required to change the posture of the center rod 41, L1 × F1 = L2 × F2 (that is, F1 = (L2 / L1) × F2), and since L2 <L1, F1 <F2.
[0041]
Accordingly, the force required to change the posture of the central collar 41 in the spell release posture to the spell posture may be smaller in the present invention having the operation piece 43 than in the conventional one without the operation piece 43. I understand.
[0042]
In this regard, as shown in FIG. 6B, when the posture of the center rod 41 set to the spelling posture is changed to the spelling release posture, the direction in which the force is applied is just opposite to the above. This is the same in that the present invention can be operated with less force than the conventional one.
[0043]
【The invention's effect】
According to the binding tool of claim 1, with the pair of binding legs passing through the binding holes of the document, the binding legs are inserted into the insertion holes of the pressing metal fittings and are set in the release posture. By pressing the center rods downward, the side rods move in directions away from each other while pushing down the spell legs protruding upward from the insertion holes while being guided by the presser fitting. By setting the spelling posture, the spell leg is pressed and clamped between the side heel and the presser fitting, and thereby the document can be put in a state of being bound by the binding tool.
[0044]
On the other hand, by pinching the tip of the operation piece with a finger while the document is bound to the binding tool, the pair of central scissors are bent upwards so that the connection position of the pair of central scissors is inverted V-shaped on the presser In addition to the upright position, the side rods move in directions close to each other, thereby changing the posture of the locking rod from the spelling posture to the releasing posture. And when the locking hook is set to the release posture, the pressing pinching between the side hooks of the binding foot and the presser fitting is canceled, so the document is removed from the binding tool by pulling out the binding foot from the insertion hole of the presser fitting. Can be removed.
[0045]
And since the operation piece is attached to the upper surface of one central rod so as to extend over the upper surface of the other central rod, when changing the position of the locking rod, the tip of the operation piece and the bending position of the central rod , That is, the distance between the moment fulcrum and the force point is longer than that in the case where there is no operation piece . Therefore, it is possible to more easily press and raise the central rod than before.
[0046]
According to the binding tool of claim 2, since the operation piece is detachably attached to the central collar, by preparing in advance a plurality of types of operation pieces with various designs, the operation piece can be selected according to preference. Can be replaced. In addition, it is possible to easily make an order to which an operation piece prepared according to a customer's request is attached.
