Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a file binding tool applied to a file.
[0002]
[Prior art]
Recently, in view of requests for separation and recycling, a file binding tool that can be easily separated from a file cover at the time of disposal has been considered. As an example, there is known a technique in which a binding tool body attached to the inner surface side of a file cover is slid and moved and fixed to a fixing member attached to the outer surface side of the file cover. This file binding tool restricts movement of the binding tool main body in the slide mounting direction (direction in which the binding tool main body is mounted at a predetermined mounting position) and movement in a direction substantially orthogonal to the slide mounting direction on the fixing member. And a plate-shaped stopper formed by cutting and raising a part of the fixing member in a substantially straight line when viewed from the side at a predetermined angle with respect to the slide mounting direction, and restricting the edge of the binding tool body at the predetermined mounting position. The movement of the binding tool main body in the slide mounting direction and the movement in the direction substantially perpendicular to the slide mounting direction are regulated by being brought into contact with or close to the portion, and the lower surface of the binding tool main body is formed by pressing from below. Slide removal direction of the binding tool body by bringing the curved surface constituting the step into contact with the tip of the stopper (how to remove the binding tool body at a predetermined mounting position) Also moving in the) are adapted to regulate (for example, see Patent Document 1).

[Problems to be solved by the invention]
However, the above is a configuration in which the curved surface of the binding tool main body is brought into contact with the tip of the stopper that is cut and raised substantially in a straight line when viewed from the side at a predetermined angle with respect to the slide mounting direction. When the relative position of the binding tool body and the fixing member slightly changes due to the force from the outside or the outside, the tip of the stopper is easy to slide against the curved surface of the binding tool body, and the initial contact state is easily released, As a result, movement of the binding tool body in the slide removal direction is allowed. As described above, since the tip of the stopper and the curved surface of the binding tool body are in contact with each other in a manner almost close to line contact, the contact state becomes unstable, and there is a problem that a stable mounting state cannot be maintained. Arise.
[0005]
Further, the stopper is left in a state where one end portion is connected to the fixing member, and a small piece formed by cutting the three sides into a substantially U-shape is pressed from below with a little elasticity applied to the one end portion. Since it is cut and raised substantially in a straight line when viewed from the side (see FIG. 14 of the above-mentioned patent document), when the cutting and raising is insufficient, the tip of the stopper and the curved portion of the binding tool body are reliably brought into contact with each other. It becomes difficult to make it. Therefore, in order to ensure that the tip of the stopper and the curved surface of the binding tool main body are in contact with each other, there may be a mode or a mode in which the stopper is pushed up from the outer surface side of the file cover using an appropriate tool. It must be used, resulting in a problem that the mounting workability is impaired.
[0006]
The present invention has been made paying attention to such a problem, and the main object is to use a simple structure and to maintain a stable attachment state between the binding tool body and the fixing member. It is in providing tools.
[0007]
[Means for Solving the Problems]
That is, the file binding tool of the present invention includes a binding tool body that is attached to the inner surface side of the file cover, and a fixing member that is attached to the outer surface side and detachably fixes the binding tool body by sliding movement. The fixing member is inserted into the insertion hole of the file cover formed at the predetermined mounting position of the fixing member on the file cover, and is protruded from the outer surface side to the inner surface side, so that the binding tool body moves in the slide mounting direction and in the slide mounting direction. It has a restricting portion that restricts movement in a substantially orthogonal direction, and has a contact surface that is erected in a posture that forms a right angle or an acute angle with respect to the slide mounting direction on one of the binding tool body and the fixing member. By providing a stopper and bringing the other part into contact with the contact surface, the sliding movement of the binding tool body located at the predetermined mounting position in the slide removal direction is restricted. It assumes Rukoto.
[0008]
Here, the “slide attachment direction” means a direction in which the binding tool body is attached at a predetermined attachment position, and the “slide removal direction” means a direction in which the binding tool body at the predetermined attachment position is removed.
[0009]
In such a case, in a state where the binding tool body is mounted at a predetermined mounting position, the tool is erected in a posture that forms a right angle or an acute angle with respect to the slide mounting direction provided on one of the binding tool body or the fixing member. Since the other part is in contact with the contact surface, for example, the relative position between the binding tool body and the fixing member changes due to an erroneous operation or an external force, so that the contact surface is in contact with the other part. Even if the contact position deviates slightly, the other part of the contact surface can be brought into contact with the other part, and the movement of the binding tool body in the slide removal direction is reliably restricted and stable. The attached state can be maintained. This is due to the fact that the one part that abuts each other is a surface that stands up in a posture that forms a right angle or an acute angle with respect to the slide mounting direction. In addition, since the contact surface provided on one side of the binding tool body or the fixing member and the other part can be engaged with each other by a very simple operation of moving the binding tool body in the slide mounting direction. Compared to the above, it is possible to omit the trouble of bringing the stopper and the other part into contact with each other using a special member or tool, and it is possible to improve the mounting workability. On the other hand, at the time of disposal, for example, by changing the height position of the stopper using a tool, movement of the binding tool body in the slide removal direction is allowed, and the binding tool body can be easily detached from the fixing member. The binding tool and the file cover can be easily separated.
[0010]
As a specific embodiment of the present invention , the stopper is provided on the fixing member, and an opening is formed in a part of the binding tool main body, and the opening edge facing the slide removing direction of the opening is contacted with the contact. It is assumed to fit involved a binding tool body and the fixing member to each other by abutting the surface.
[0011]
In particular, the binding tool body includes a substrate disposed along the inner surface of the file cover, and a binding element that is attached to the substrate and binds paper sheets on the inner surface side of the file cover, In addition, a claw portion that cuts and raises a part to hold the binding element is provided, and if the opening portion is a portion that is cut to form the claw portion, the opening portion is formed by the operation of forming the claw portion. Can be formed easily, and the manufacturing process can be simplified. Paper sheets are a concept that includes not only various papers such as loose leaves and mounts, but also clear holders and underlays that can be bound.
[0012]
In order to realize a more stable mounting state, the present invention is characterized in that a plurality of the stoppers are provided and the opening is formed corresponding to the stopper.
[0013]
As a preferred embodiment of the stopper, the stopper is formed by folding back a part formed by cutting a part of the fixing member in the slide mounting direction and elastically deforming the base end of the stopper. The elastic deformation part is formed and the contact surface is provided at the tip part.
[0014]
In addition, in order to make the contact state between the contact surface and the opening edge more stable and to surely prevent the binding tool body from moving in the slide removal direction, the stopper is attached to the fixing member. It is preferable to form an operation hole that can be pushed up from the outer surface side. In this case, the operation hole is provided at a predetermined position of the fixing member where the tip of the stopper is located, and the opening width dimension of the operation hole Is set to be smaller than the width of the stopper, it is possible to prevent the tip of the stopper from being immersed in the operation hole and to reliably avoid the contact between the contact surface and the opening edge. can do.
[0015]

A narrow portion 12b having a small opening dimension is provided in a part of each binding element accommodation hole 12a, and in a state where the file cover 1 is folded, a part of the binding element 33 is lightly locked to the narrow portion 12b. It is configured as follows. The back cover 13 is formed with insertion holes 13a, 13b, 13c, and 13d into which a first restricting portion 42, a second restricting portion 43, a stopper 44, and a cylindrical portion 45 of the fixing member 4 to be described later are inserted, respectively. The insertion holes 13a, 13b, and 13c are formed with the hole edges of the insertion holes 13a, 13b, and 13c and the portions 42, 43, and 44 in a state where the first restriction portion 42, the second restriction portion 43, and the stopper 44 are inserted, respectively. On the other hand, the insertion hole 13d has a hole edge of the insertion hole 13d and an edge part of the cylindrical part 45 in a state where the cylindrical part 45 is inserted. The hole size is set so that is substantially in close contact. Each of the boundary portions 1P and 1Q is formed with a finger-hanging portion 1Y having a substantially rectangular shape in front view and having an opening size that allows a standard adult fingertip to be sufficiently inserted.
[0018]
The file binding tool 2 is attached to the binding tool body 3 attached to the inner surface 1A side of the file cover 1 with the file cover 1 interposed therebetween and the outer surface 1B side of the file cover 1 as shown in FIGS. And a fixing member 4 for detachably fixing the binding tool body 3 by sliding movement.
[0019]
The binding tool main body 3 is disposed on the inner surface 1A of the back cover 13 and is disposed on a substrate 31 having a substantially rectangular shape in plan view and having a predetermined portion bulged upward by pressing, and an upper surface 31A of the substrate 31. A thin plate-like leaf spring 32, a pair of binding elements 33 that are biased by the leaf spring 32 to perform an opening / closing operation and bind sheets (not shown) on the inner surface 1A side of the file cover 1, and an opening / closing operation of the binding element 33 An operation lever 34 for operation is provided. In the binding element 33, a first half-binding rod 331 and a second half-binding rod 332, each having a partial arc-shaped ring portion 331a, 332a at the distal end portion, bring the ring portions 331a, 332a into contact with or close to each other. In this way, it is shaped so as to form a ring shape. The pair of first half-binding rods 331 are fixed at both ends of the substrate 31 in the longitudinal direction. The pair of second half-binding rods 332 are formed by integrally deforming a single metal bar at both ends, and are connected to the pair of second half-binding rods 332. The vicinity of both ends of the connecting portion 333 is rotatably held by a pair of claw portions 31a formed by cutting and raising a part of the substrate 31, and the central portion of the connecting portion 333 is connected to the leaf spring 32. It is attached to the upper surface. An opening 31b is formed at a site cut to form each of the claw portions 31a. Each opening 31b is a fixing member which will be described later in a direction in which the binding body 3 attached to the predetermined attachment position and the fixing member 4 overlap with the file cover 1 with the binding body 3 attached to the predetermined attachment position. 4 is formed in a positional relationship corresponding to the pair of stoppers 44 formed in FIG. Therefore, at the predetermined mounting position, the corresponding opening 31b and the stopper 44 are in a relationship with each other. The operation lever 34 is rotatably attached to a protruding portion 31c having a base end protruding upward from the substrate 31, and is connected to a connecting portion 333 by a pressing portion 34a (see FIG. 6) provided near the base end. The leaf spring 32 is pressed downward to hold the binding element 33 in the closed state. When the user grips the operation end 34 b of the operation lever 34 and pivots upward, the pressed state of the leaf spring 32 and the connecting portion 333 is released, and the second half-binding rod 332 is moved by the leaf spring 32. The binding element 33 is rotated in the direction in which the binding element 33 is opened and the sheets can be bound to the binding element 33. Paper sheets are a concept including not only those made of various paper materials such as loose leaves and mounts, but also a clear holder that can be bound, an underlay, and the like.
[0020]
As shown in FIGS. 4 to 6 (FIG. 5 (a) is a plan view, FIG. 5 (b) is a cross-sectional side view along line yy in FIG. 5A), etc. A substrate 41 made of a sheet metal material or the like having a substantially rectangular shape in plan view is processed. Specifically, the first restricting portion 42 that restricts the movement of the binding tool body 3 in the slide mounting direction is provided at one end in the short dimension direction of the substrate 41, and the binding tool is provided at both ends in the long dimension direction of the substrate 41. The 2nd control part 43 which controls the movement to the direction orthogonal to the slide attachment direction of the main body 3 is provided. Here, the slide mounting direction means a direction (direction of arrow A in FIG. 6) in which the binding tool body 3 is mounted at a predetermined mounting position, and the slide removal direction used in the following description means binding at the predetermined mounting position. The direction which removes the tool main body 3 (arrow B direction in the same figure) is meant. The first restricting portion 42 has a substantially L-shaped side surface formed by bending a substantially central portion at one end in the short direction of the substrate 41 upward at a substantially right angle and further bending in a slide removing direction. Each of the predetermined regions at both ends in the longitudinal direction of the substrate 41 is bent substantially upward at a right angle, and further bent toward the central portion in the longitudinal direction. Further, a stopper 44 is formed by cutting a part of the substrate 41 in the vicinity of both ends in the longitudinal direction into a substantially rectangular shape and folding back the opened part at a predetermined angle in the slide mounting direction. The stopper 44 has an elastically deformable portion 44a that can be elastically deformed at the base end portion, and an abutment surface 44b that is bent at a substantially right angle with respect to the slide mounting direction is integrally formed at the distal end portion. An inclined piece 44c extending along the slide mounting direction is provided at the tip of the head. An operation hole 41a having a substantially rectangular shape in plan view penetrating in the thickness direction of the substrate 41 is formed in a lower portion of the tip end portion of the stopper 44 including the contact surface 44b and the inclined piece 44c. Here, the opening width dimension 41 x of the operation hole 41 a is set smaller than the width dimension 44 x of the stopper 44. A cylindrical portion 45 that protrudes upward is integrally provided at a predetermined position displaced toward the center in the longitudinal direction of the substrate 41 with respect to the stopper 44. The cylindrical portion 45 has a pipe shape penetrating vertically, and the outer diameter is set slightly smaller than the diameter of the insertion hole 13 d formed in the back cover 13.
[0021]
Next, a procedure for attaching the file binding tool 2 including the binding tool body 3 and the fixing member 4 having the above-described configuration to the file cover 1 will be described with reference to FIG.
[0022]
First, the fixing member 4 is positioned on the outer surface 1B side of the back cover 13, and the first restricting portion 42, the second restricting portion 43, the stopper 44, and the cylindrical portion 45 provided on the fixing member 4 are formed on the back cover 13. The substrate 41 of the fixing member 4 is brought into contact with or close to the outer surface 1B of the file cover 1 so as to be inserted into the insertion holes 13a, 13b, 13c, and 13d from the outer surface 1B of the back cover 13 and protrude toward the inner surface 1A. At this time, the position of the fixing member 4 with respect to the file cover 1 is determined by inserting the cylindrical portion 45 having substantially the same diameter size into the insertion hole 13d. Thus, the cylindrical part 45 and the insertion hole 13d serve as a positioning part. Next, when the binding tool main body 3 is moved in the slide mounting direction along the inner surface 1A side of the back cover 13 while being guided by the second restricting portion 43 of the fixing member 4, one of the substrates 31 of the binding tool main body 3 at a predetermined position. When the edge 31d interferes with the stopper 44 and the binding tool body 3 moves in the slide mounting direction, the stopper 44 temporarily moves into the operation hole 41a due to elastic deformation of the elastic deformation portion 44a provided at the base end portion of the stopper 44. It sinks to the side (FIG. 6 (a)). Subsequently, when the binding tool body 3 is moved in the slide mounting direction to a position where the edge 31 d of the substrate 31 abuts on the first restricting portion 42 of the fixing member 4, the substrate 41 of the fixing member 4 is formed above the stopper 44. The operation hole 41a is positioned, the interference state between the edge 31d of the substrate 31 of the binding tool body 3 and the stopper 44 is released, and the stopper 44 rises to its original position by the restoring force of the elastic deformation portion 44a (see FIG. (B)). In this state, when the binding tool body 3 is moved in the slide removal direction, the opening edge 31b1 facing the removal direction of the opening 31b comes into contact with the contact surface 44b of the stopper 44, and the slide removal of the binding tool body 3 is performed. Movement in the direction is restricted. At the same time, the first restricting portion 42 restricts movement of the binding tool body 3 in the slide mounting direction, and the second restricting portion 43 also restricts movement of the binding tool body 3 in the direction perpendicular to the slide attachment direction. Is done. Through the above procedure, the file binding tool 2 is attached to the file cover 1 integrally so as to fix the binding tool body 3 at a predetermined mounting position. By using the operation hole 41a of the fixing member 4 to push up the tip end portion of the stopper 44 from the outer surface 1B side of the back cover 13 with a tool such as a flathead screwdriver, the contact surface 44b and the opening edge You may make it contact | abut 31b1 reliably.
[0023]
Further, at the time of disposal, the contact state between the opening edge 31b1 and the contact surface 44b is released by pushing down the tip of the stopper 44 toward the operation hole 41a using the tool from the opening 31b. The binding tool body 3 is removed from the fixing member 4 by moving the binding tool body 3 in the slide removal direction. Then, the file binding tool 2 and the file cover 1 are separated by removing the fixing member 4 from the back cover 13.
[0024]
As described above, the file binding tool 2 according to the present embodiment includes the binding tool body 3 attached to the inner surface 1A side of the file cover 1 and the attachment tool body 3 attached to the outer surface 1B side by sliding movement. A fixing member 4 that can be fixed, and the fixing member 4 is inserted into the insertion holes 13a and 13b of the file cover from the outer surface 1B side of the file cover 1 and protrudes toward the inner surface 1A. It has the 1st control part 42 and the 2nd control part 43 which control the movement to the direction substantially orthogonal to a mounting direction and a slide mounting direction, Comprising: It fixes to the fixing member 4 with respect to a slide mounting direction. A stopper 44 having a contact surface 44b erected in a right-angled posture is provided, and an opening edge 31b1 facing the slide removing direction of the opening 31b formed in the binding tool body 3 is provided on the contact surface 44b. By making contact, the sliding movement of the binding tool main body 3 located at the predetermined attachment position in the slide removal direction is restricted, so that the binding tool main body 3 and the fixing member 4 are relatively moved by an erroneous operation or external force, for example. Even if the position changes and the contact position between the contact surface 44b and the opening edge portion 31b1 is slightly shifted, the opening edge portion 31b1 can be contacted to another part of the contact surface 44b. It is possible to reliably regulate the movement of the binding tool body 3 in the slide removal direction and maintain a stable attachment state. Further, since the contact surface 44b and the opening edge 31b1 can be engaged with each other by a very simple operation of moving the binding tool body 3 in the slide mounting direction, it is possible to improve the mounting workability. . In addition, at the time of disposal, the height position of the tip of the stopper 44 is lowered using a tool to allow the binding tool body 3 to move in the slide removal direction, and the binding tool body 3 can be easily removed from the fixing member 4. The file binding tool 2 and the file cover 1 can be easily separated.
[0025]
In particular, the binding tool body 3 includes a substrate 31 arranged along the inner surface 1A of the file cover 1 and a binding element 33 attached to the substrate 31 and binding sheets on the inner surface 1A side of the file cover 1. The claw portion 31a that holds the binding element 33 by cutting and raising a part thereof is provided on the substrate 31, and the opening portion 31b is a portion that is cut to form the claw portion 31a. Thus, the opening 31b can be easily formed, and it is not necessary to carry out any special processing to form the opening 31b, thereby simplifying the manufacturing process.
[0026]
Further, since the stoppers 44 are provided as a pair and the openings 31b are formed as a pair corresponding to the stoppers 44, a more stable mounting state can be realized.
[0027]
Further, since the stopper 44 is formed by folding back a part of the substrate 41 of the fixing member 4 formed in the slide mounting direction, the stopper 44 can be easily formed. In addition, the stopper 44 Since the elastically deformable portion 44a that can be elastically deformed is formed at the base end portion and the contact surface 44b is provided at the distal end portion, the restoring force of the elastically deformable portion 44a can be increased. The contact surface 44b and the opening edge 31b1 can be contacted more reliably by the restoring force.
[0028]
Also, since the fixing member 4 is formed with an operation hole 41a capable of pushing up the stopper 44 from the outer surface 1B side of the file cover 1, the elastic deformation can be achieved by pushing up the stopper 44 from below using the operation hole 41a. Combined with the restoring force of the portion 44a, the contact surface 44b and the opening edge portion 31b1 can be contacted more reliably, and the binding tool body 3 can be prevented from moving in the slide removal direction and can be attached in a good state. Can be realized.
[0029]
In particular, since the operation hole 41a is provided in the substrate 41 of the fixing member 4 where the tip of the stopper 44 is located, the stopper 44 can be easily pushed up, and the opening width dimension 41x of the operation hole 41a is set to the stopper 44 is set smaller than the width dimension 44x of 44, the tip end portion of the stopper 44 is prevented from entering the operation hole 41a, and the contact surface 44b and the opening edge portion 31b cannot be brought into contact with each other. Can be effectively avoided.
[0030]
The present invention is not limited to the embodiment described in detail above.
[0031]
For example, the abutting surface is not limited to one that is erected at right angles to the slide mounting direction, and any one that is erected at an acute angle with respect to the slide mounting direction can be suitably used.
[0032]
Moreover, in the said embodiment, what provided the stopper in a pair is employ | adopted, However, You may increase / decrease the number of stoppers suitably. In that case, the opening may be formed corresponding to the stopper.
[0033]
The file binding tool is not limited to one having a pair of binding elements, and may of course have a plurality of binding elements.
[0034]
Further, a stopper may be provided on the binding tool body, and a part of the fixing member may be brought into contact with the stopper.
[0035]
In addition, the specific configuration of each part is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention.
[0036]
【The invention's effect】
As described above, according to the present invention, in a state in which the binding tool main body is mounted at a predetermined mounting position, it stands in a posture that forms a right angle or an acute angle with respect to the slide mounting direction provided on one of the binding tool main body or the fixing member. Since the other part is in contact with the abutted contact surface, for example, the relative position between the binding tool main body and the fixing member changes due to erroneous operation or external force, and the contact surface and the other part of the other Even if the abutting position is slightly deviated, the other part of the abutting surface can be abutted against the other part, and the movement of the binding tool body in the slide removal direction is reliably restricted. Thus, a stable mounting state can be maintained. In addition, since the contact surface provided on one side of the binding tool body or the fixing member and the other part can be engaged with each other by a very simple operation of moving the binding tool body in the slide mounting direction. For example, it is possible to omit the trouble of bringing the stopper and the other part into contact with each other using a special member or tool, and to improve the mounting workability. In addition, at the time of disposal, the height of the stopper is lowered using a tool to allow movement of the binding tool body in the slide removal direction, and the binding tool body can be easily detached from the fixing member. And file cover can be easily separated.
