JP 2002-307484 A

However, the binding tool disclosed in Patent Document 1 requires a complicated mechanism for synchronously moving the moving members, which increases the number of parts.
In addition, when the operation unit is operated to release the binding, the operation unit is bent in a mountain shape, and when the operation unit is pressed to the base side, the operation force is orthogonal to the base. There is a tendency to become difficult to give in the direction.
In addition, there is a disadvantage that the initial resistance when the binding leg is laid down is strong and a smooth operation feeling cannot be obtained.

[Object of invention]
The present invention has been devised by paying attention to such inconveniences, and the object of the present invention is to reduce the number of parts and always keep the path of the binding foot when the pressing member is in the position to release binding. It is to provide a binding tool and a file that can be kept open.

  Another object of the present invention is to provide a binding tool and a file excellent in operability that can reliably apply an operating force to the pressing member.

  Furthermore, an object of the present invention is to provide a binding tool and a file that can reduce the initial resistance force when the binding foot is tilted, and can smoothly set the binding foot to the binding position. is there.

In order to achieve the above object, the present invention includes a plurality of passages through which a plurality of binding feet respectively pass, a base having a shape extending in a longitudinal direction, and a base positioned on the base, and the passages are simultaneously disposed. In a binding tool including a binding position that shuts down and lowers the binding foot, and a pressing member that is displaceable between a position that simultaneously opens each passage and releases binding,
The base includes a guide portion provided on both sides in the longitudinal direction, and a pair of connecting members connected to the pressing member at a position inside the guide portion so as to be relatively displaceable.
The pressing member is connected to the operating portion, a pair of pressing plates that are connected to the operating portion so as to be bendable and that blocks and opens the passage, and the pressing plate is provided on the pressing plate. A mounting portion supported movably,
The base and the pressing member can be combined by connecting the base and the pressing member via the connecting member in a state where the mounting portion is supported by the guide portion,
When an operation force is applied in a direction in which the operation unit moves away from the base, the outer end portion of the pressing plate moves along the guide unit to perform the binding and release. ing.

  In the present invention, the pair of connecting members are provided so as to be displaced symmetrically when the pressing member is displaced.

  Further, the connecting member has a configuration in which when the pressing member is in the position where the binding is released, the relative position between the base and the pressing member is maintained and the open state of the passage is maintained.

  Furthermore, an auxiliary member that can be displaced following the displacement of the connecting member is provided between the middle of the connecting member and the base, and the auxiliary member is released when the pressing member releases the binding. It is preferable to adopt a configuration in which the relative position between the base and the pressing member is supplementarily held.

  Further, the pressing member may be configured to be displaceable in a state in which the operation unit maintains a horizontal position.

  Moreover, the outer side edge part of the said press board acts as a contact part which provides the initial lying force to the said binding leg, and is comprised so that it may be located higher than the said attachment part.

  Furthermore, the file according to the present invention includes the above-described binding tool and a cover body to which the binding tool is attached, and the binding foot has a configuration in which a base portion is supported by the cover body.

  According to the present invention, since the base and the pressing member are combined in a state where the base and the pressing member are connected via the connecting member, the binding tool can be configured by the binding foot, the base, and the pressing member. it can. In addition, it is possible to simultaneously perform binding and release operations on each binding foot simply by applying an operating force to the operation unit, and there is no need to provide additional parts such as a pinion.

  Further, due to the configuration in which the connecting member is displaced symmetrically, the operating force can be equally applied to both sides of the pressing member when the operating force is applied to the operating portion.

  Further, since the connecting member is provided so as to maintain the state in which the binding is released with respect to the base, the binding operation can be quickly performed by always maintaining the state in which the passage is opened when binding the paper. It can be carried out.

  Moreover, according to the structure which provided the auxiliary member, the state which the press member released the binding can be maintained more reliably.

  Further, if the pressing member can be displaced while the operation portion of the pressing member is kept in a horizontal position, it is possible to avoid the inconvenience that the fingertip is damaged when the operating force is applied.

  In addition, by setting the outer end of the plate-like body higher than the attachment portion, it can be set so that the force when bending the binding foot is applied upward away from the base of the binding foot, and the binding foot is bent. The resistance in the initial stage of the operation of lying down can be relaxed. Therefore, the binding leg can be bent and laid down with a smaller operating force than the conventional product.

A plurality of convex portions 23 are provided to prevent this.

  On the inner side of the position where the guide portion 20 is formed, a pair of connecting members 25 that are integrally formed with the base 15 and connect between the base 15 and the pressing member 16 are provided at positions that are symmetrical. It has been. As shown in FIGS. 5 to 8, the connecting member 25 includes a bent piece member 27 that is connected to the plate-like body 19. One end of the bent piece member 27 is connected to the vicinity of the center of the plate-like body 19 via a hinge portion 29, and convex portions for connecting to the pressing member 16 are provided on both sides in the width direction on the other end side. Each part 30 is provided. The bent piece member 27 is disposed in a hole 32 formed in the plane of the plate-like body 19, and a rib 34 positioned so as to partially narrow the hole width is formed on the inner peripheral side of the hole 32. It is formed at a relative position in the width direction. As shown in FIGS. 3 and 5, the bent piece member 27 is connected to the pair of widthwise inclined portions 35 extending from the hinge portion 29 and the inner surface of the tip of the inclined portion 35 in the left-right direction of the hole 32. The intermediate portion 36 extends and a tip portion 37 extended from the tip of the intermediate portion 36, and the convex portion 30 is formed on each outer surface side of the tip portion 37.

  An auxiliary member 40 is disposed between the tip of the inclined portion 35 and the rib 34. The auxiliary member 40 is provided in a pair in the width direction so that the bent piece member 27 can be positioned in the middle. The base piece 42 is hinged to the upper end of the rib 34, the tip of the base piece 42, and the inclined portion. 35 and a connecting piece 43 positioned between the two. Both ends of the connecting piece 43 are connected to the base piece 42 and the inclined portion 35 so as to be bendable.

When an operation force along the middle / upper / lower direction is applied, the binding in which the length of the plan view is changed to lie down on the binding foot 13 and the binding is released.

  The pressing member 16 is connected to the operation portion 50 via the hinge portion 51 and the operation portion 50 located in the central portion in the longitudinal direction so as to be bendable, and the binding member 13 is bound when the binding foot 13 is laid down. A pair of pressing plates 53 positioned on the upper surface side of the foot 13 is provided. The operation unit 50 includes side walls 55 on both sides in the width direction, and these side walls 55 make it easy to pick the operation unit 50 from both sides in the width direction. Further, the pressing plate 53 has a shape including side walls 56 on both sides in the width direction, and the pressing plate 53 has an outer end portion 53 </ b> A as a contact portion that applies an initial lying force to the binding foot 13. It comes to work.

  As shown in FIG. 10, each outer region of the side wall 56 of the pressing plate 53 is provided with a relatively large vertical width, and its tip side protrudes outward via an inclined edge 56A, and its tip corner. Inward projections 60 that are located in the guide portion 20 of the base 15 and are movable along the guide portion 20 are respectively formed on the inner surface of the base portion 15. A large separation width corresponding to the dimension L can be secured between the lower surface and the lower surface.

  A pair of bearing portions 62 as attachment portions are disposed along the width direction on the lower surface of the substantially central portion in the surface of the pressing plate 53, and the bearing portion 62 is arranged on the outer surface side of the distal end portion 37 of the bent piece member 27. The provided protrusions 30 are fitted in a rotatable state.

  When assembling the binding tool 10, the pair of protrusions 60 provided on both sides in the longitudinal direction of the pressing member 16 are positioned on the guide portion 20 of the base 15 with the pressing member 16 positioned on the upper surface side of the base 15. Let Next, the operating portion 50 of the pressing member 16 is picked so that a space is formed between the pressing member 16 and the base 15, and the convex portion 30 of the connecting member 25 is fitted to the bearing portion 62 of the pressing member 16. Thereby, the combination of the base 15 and the pressing member 16 can be completed.

  Next, the usage method of the binding tool 10 is demonstrated with reference also to FIG.11 and FIG.12.

When the paper P is bound using the binding tool 10, the operation unit 50 of the pressing member 16 is kept at a position separated from the base 15 (see FIG. 2).
That is, the side wall 55 of the operation unit 50 is picked with a fingertip, and a force is applied in an upward direction perpendicular to the surface of the base 15, whereby the protrusions 60 provided on both sides move to the inside of the guide unit 20. At the same time, the convex portion 30 on the distal end side of the connecting member 25 is rotatably supported by the bearing portion 62 on the pressing member 16 side, so that the convex portion 30 side is rotated and displaced upward via the hinge portion 29. . That is, the pressing member 16 and the connecting member 25 are displaced in a state similar to a pantograph. In the intermediate stage from the start of displacement of the connecting member 25 to the position shown in FIG. 2 (binding release position), the protrusion 30 is connected to the bearing portion 62 in relation to the connecting member 25. Is bent so as to be shifted inward from the position that should originally pass when assuming that it has an initial shape in an unloaded state. At this time, the auxiliary member 40 connected to the connecting member 25 is temporarily bent in the direction of reducing the bending angle between the base piece 42 and the connecting piece 43 with respect to the initial shape when there is no deformation in the unloaded state. Displace upward.

  When the operation unit 50 is separated to the maximum with respect to the base 15 (when in the binding release position in FIG. 2), the connecting member 25 is still bent and deformed while the degree of bending is weakened. The position of the convex portion 30 that is shifted inward from the original position when there is no action is taken, and the repulsive force that tries to return to the original position acts to apply the pressing plate 53 obliquely outward and upward. . At this time, the auxiliary member 40 maintains a bent shape with respect to the initial shape, and applies a force obliquely upward to the connecting portion between the connecting piece 43 and the connecting member 25, Supporting from below, the connecting member 25 backs up the action of maintaining the binding release position of the pressing member 16. Thereby, the position where the projection 60 is stationary at the guide portion 20 is maintained, and the passage 14 is always kept open.

  After inserting the binding foot 13 into the binding hole of the sheet P with the folding portion 11 on the file inner surface side as the receiving surface in a state where the passage 14 is opened in this way, that is, in a state where the binding of the binding foot 13 is released, The base 15 is positioned from the lateral direction so that the binding foot 13 is positioned in the passage 14, and the base 15 is positioned on the paper P (see FIG. 2).

  Next, as shown in FIG. 11, a fingertip is applied to the upper surface of the operation unit 50 to apply an operation force toward the base 15. Then, the connecting member 25 and the auxiliary member 40 that have held the position of the pressing member 16 are rotationally displaced. In the pressing member 16, the protrusions 60 on both ends move outward along the guide portions 20, respectively. Displace to increase the length. At this time, the outer end 53 </ b> A of the pressing plate 53 comes into contact with the binding foot 13, and a force is applied in a direction in which the binding foot 13 is laid down outward. In the present embodiment, since the protrusion 60 is set so as to be positioned higher than the protrusion 60 by the dimension L described above, the portion where the binding foot 13 is about to be bent is higher than the upper surface of the guide portion 20. This increases the bending resistance.

  If the downward force is continuously applied to the operation unit 50 in a state where the binding foot 13 starts to bend (see FIG. 12), the outer end 53A slides on the upper surface of the binding foot 13 and further collapses the binding foot 13. On the other hand, when the connecting member 25 and the auxiliary member 40 gradually enter the hole 32 of the base 15 and the operation unit 50 hits the upper surface of the central portion of the base 15, the pressing member 16 and the base 15 are not shown. The binding position is maintained by engaging with each other via the stopper.

  Therefore, according to such an embodiment, the sheet P is bound by moving the both sides of the pressing member 16 at the same time by the operation of moving the pressing member 16 away from the base 15 with a small number of parts. A binding tool that can be released can be provided.
