Description

  The present invention relates to a paper pressing member, a binding tool, and a file, and more particularly, to a paper pressing member, a binding tool, and a file that prevent a bound document from flapping.

  Conventionally, as a binding tool used for a ring file or the like, for example, as shown in FIG. 7, a base 51 in a plan view long piece fixed to a spine of a file or the like, or the vicinity thereof, and the base 51 Are provided on the other end side of the base 51 so as to be opposed to the first binding shafts 50A and 50A provided at two locations in the longitudinal direction and the first binding shafts 50A and 50A. In this case, there are known ones constituted by second binding shafts 50B and 50B engaged with the first binding shafts 50A and 50A, respectively. As the engagement structure when the first and second binding shafts 50A and 50B form a closed loop, in addition to the structure based on the tip end, for example, as shown in Patent Document 1, the axial direction of the binding shaft 50 Structures that engage in intersecting directions are known. That is, the structure which cancels | releases engagement with the 2nd binding axis | shaft 50B and 50B by giving a force in the direction which puts a finger so that these may be straddled across the 1st binding axis | shaft 50A and 50A, and mutually adjoins them. Exists. According to this structure, there exists an advantage that operation force can be made small compared with a front end butting type binding tool.

  By the way, in the case of such a binding tool, in order to prevent the bound document P from flapping along the axial direction of the binding shaft 50, the surface of the long strip-shaped plate member 52 is used. In some cases, a paper pressing member 55 having a slot-like passage 53 through which the binding shaft 50 can pass is used. The paper pressing member 55 includes a narrow slot 53A and a wide slot 53B in which the width of the passage 53 extends along the longitudinal direction of the paper pressing member 55, and the second binding shaft 50B is positioned in the narrow slot 53. As described above, when the paper pressing member 55 is moved along the longitudinal direction, the paper pressing member 55 is maintained at a position fixed to the second binding shaft 50B, and fluttering of the document P can be prevented. Become.

However, as shown in FIG. 8, when the paper pressing member 55 is moved upward in FIG. 8 so that the second binding shaft 50B is positioned in the wide slot 53B, each path is connected to the second binding shaft 50B. Since the lower end portions 53C and 53C in FIG. 53 collide with each other at the same time, the second binding shaft 50B located in the upper part in FIG. 8 is tilted by the impact at that time, and the first binding corresponding to this tilts. This causes a disadvantage that the engagement with the shaft 50A is released.

In addition, the structure for preventing such inconvenience is to change the length or shape of the passage slightly, and does not require any additional cost, and the configuration is extremely simple. can do.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 shows a schematic perspective view of a main part in a state in which a file having a binding tool is opened, and FIG. 2 shows a schematic perspective view in a state in which the binding tool is opened. In these drawings, a file 10 includes a cover body 14 having a front cover 12 and a back cover 13 that are connected via a spine cover 11 in the middle, and a binding tool 15 fixed to the inner surface side of the back cover 13. It is configured.

  The binding tool 15 extends substantially parallel to the longitudinal direction of the spine cover 11 and is attached to the back cover 13 via rivets 17, 17, and one end of the base 18, that is, the spine cover. The two first binding shafts 19 and 19 are rotatably supported at a predetermined distance from each other at the end portion on the 13th side, and are opposed to the first binding shafts 19 and 19 at the other end portion of the base 18. A binding tool body including two second binding shafts 20 and 20 which are rotatably supported at positions and which form closed loops with the base 18 in association with the respective distal end portions of the first binding shafts 19 and 19. 21 and a paper pressing member 22 attached to the binding tool main body 21. Here, each member constituting the binding tool main body 21 is configured by using a metal material such as stainless steel, while the paper pressing member 22 is configured by an integrally molded product made of a resin material.

  The first binding shaft 19 is provided in a substantially semicircular shape when viewed from the front, while the second binding shaft 20 is provided in a substantially L shape when viewed from the front, and is provided between the front ends of the binding shafts 19 and 20. The closed state which becomes a closed loop is maintained through the engaged portion 27, and the engagement portions 27 are released so that the end portions of the binding shafts 19 and 20 can be opened. As shown in FIG. 3, the engaging portion 27 is formed at the distal end portion of the first binding shaft 19 and at the distal end portion of the second binding shaft 20. An inward hook-shaped portion 29 that can engage with the facing hook-shaped portion 28 is formed. When the engagement portion 27 applies an operating force so that the tip ends of the first binding shafts 19 and 19 are close to each other, the tip portions of the first binding shafts 19 and 19 are connected to the second binding shaft. The first binding shafts 19 and 19 are provided so as to be able to incline in directions approaching each other without interfering with the 20, 20 and maintaining the shape of the first binding shafts 19. The engagement with the shafts 20 and 20 can be released.

  The first and second binding shafts 19 and 20 are supported by a plurality of connection plates (not shown) arranged in the internal space of the base 18, and the first and second binding shafts and springs are not always shown through the connection plates and a spring (not shown). A force is applied in a direction in which the closed loop by the second binding shafts 19 and 20 is released. Note that the internal space structure of the base 18 in the present embodiment is substantially the same as the structure described in Japanese Patent Application Laid-Open No. 2003-251973. Therefore, detailed description is omitted here.

  The paper pressing member 22 is not particularly limited, but is provided in a substantially long piece shape in plan view that is longer than the length connecting the second binding shafts 20 and 20 and shorter than the length of the base 18. It has been. The paper pressing member 22 is stretched between the second binding shafts 20, 20, whereby the paper P as a paper sheet is sandwiched between the base 18 or the back cover 13. It is possible. The paper pressing member 22 includes passages 25 and 26 through which the second binding shafts 20 and 20 pass, respectively, in the length direction. The passages 25 and 26 are fixed positions by tightening the standing shaft portions of the second binding shafts 20 and 20 from the outside in the radial direction when the paper pressing member 22 is moved to the position shown in FIG. Narrow slots 25A and 26A serving as tightening portions to be maintained, and wide slots 25B and 26B serving as opening portions for releasing the fixing when the paper pressing member 22 is moved downward in FIG. Here, the narrow slot 25 </ b> A is positioned on the outer end side of the passage 25, while the narrow slot 26 </ b> A is positioned on the inner end side of the passage 26. Accordingly, the passages 25 and 26 have asymmetric shapes with respect to the virtual center line C in FIG.

  Of the two passages 25 and 26, the passage 25 located at the upper side in FIG. 3 is moved when the paper pressing member 22 is moved from the position where the paper pressing member 22 is held at the fixed position to the position where the fixing is released, that is, FIG. As shown in FIG. 4, when the paper pressing member 22 is moved upward, the length of the lower passage 26 is set so as not to apply a force for releasing the engagement between the first and second binding shafts 19 and 20. Long dimensions are provided. More specifically, as shown in FIG. 4, the distances L and L between the outer ends of the passages 25 and 26 with respect to the virtual center line C of the paper pressing member 22 are substantially equal to each other. The length L2 of the passage 25 is set to be longer than the length L3 of the passage 26 by a length L4. Therefore, even when the second binding shaft 20 contacts the outer end 26C of the passage 26, the second binding shaft 20 does not contact the inner end 25C of the passage 25.

  In the above configuration, when the document P is pressed by the paper pressing member 22, the second binding shafts 20 and 20 are inserted into the narrow slots 25A and 26A of the passages 25 and 26, as shown in FIGS. What is necessary is just to move the paper pressing member 22 so that it may be located. Accordingly, the second binding shafts 20 and 20 receive the tightening force from the radially outer side by the narrow slots 25A and 26A to keep the paper pressing member 22 in a fixed position, and prevent the document P from being lifted and fluttered. It becomes.

  As shown in FIG. 4, the paper pressing member 22 is moved with respect to the position shown in FIG. 3 when the document P is added or removed or when the document P is moved to the first binding tool 19 or 19 side. You can do it. By this movement, the second binding shafts 20 and 20 are positioned in the wide slots 25B and 26B, and the tightening force is released. At this time, the outer end 26C of the passage 26 preferentially collides with the second binding shaft 20 located in the lower part in FIG. 4, and a force directed from the outside to the inside is applied to the second binding shaft 20. However, since the second binding tool 20 is the inward hook-shaped portion 29, the second binding tool 20 bites into the first binding tool 19 strongly, and the engagement between the two is not released. On the other hand, the second binding shaft 20 located on the upper side is an inwardly saddle-shaped portion 29, and the second binding shaft 20 hits the inner end 25C of the passage 25 due to the presence of the dimension L4. Since there is nothing, the force in the direction of releasing the engagement is not physically applied. Accordingly, in this state, the paper pressing member 22 can freely move along the first and second binding shafts 19 and 20, and the fingers are placed between the first binding shafts 19 and 19 to each other. By applying an external force in a direction to approach the second binding shaft 20, the engagement with the second binding shafts 20, 20 can be released, and the tip portion can be opened.

  Therefore, according to such an embodiment, it is possible to reliably prevent inadvertent closed loop release when the paper pressing member is applied to a binding tool that releases the closed loop by the mutually approaching operation of the binding axes. Become.

Although the best configuration, method and the like for carrying out the present invention have been disclosed in the above description, the present invention is not limited to this.
That is, the invention has been illustrated and described with particular reference to particular embodiments, but it should be understood that the above-described embodiments are not deviated from the technical idea and scope of the invention. On the other hand, those skilled in the art can make various modifications in the detailed configuration such as shape, position, quantity, and the like.
Accordingly, the description limited to the shape, position, quantity, etc. disclosed above is an example for easy understanding of the present invention, and does not limit the present invention. The description by the name of the member which remove | excluded the limitation of one part or all of such is included in this invention.

  For example, in the above-described embodiment, the case where the paper pressing member 22 is mounted between the second binding shafts 20 is illustrated and described, but the paper pressing member 22 is mounted between the first binding shafts 19 and used. You may do it. In this case, when the paper pressing member 22 is moved from the fixed position to the fixed release position and the inner end 25C of the upper passage 25 in FIG. 4 hits the first binding shaft 19, the lower first binding is performed. The length of the passage 26 may be set so that no inward force is applied to the shaft 19. In short, according to the present invention, it is possible to regulate the application of force that releases the engagement in accordance with the orientation of the hook-shaped portion for engaging the first and second binding shafts 19 and 20. Thus, the relative length dimensions of the passages 25 and 26 may be different.

  In addition, the binding tool according to the present invention is provided with the above-described configuration, and further prevents the use of a paper pressing member having an additional binding shaft along the longitudinal direction of the base and having a passage corresponding thereto. Absent. In this case, if the additional binding shaft is of the tip butting type, the closed loop of all the binding shafts can be released by the operation of bringing the two binding shafts close to each other.

The present invention can also employ, for example, the paper pressing member 22 shown in FIG. The paper pressing member 22 shown in the figure is provided with a convex portion 40 on the inner periphery of the passage 26 located on the lower side so that the second binding shaft 20 preferentially hits the convex portion, and the upper side The second binding shaft 20 located in the position is configured so as not to hit the inner end 25C of the passage 25.
According to such a modification, the first and second binding shafts 19 and 20 located on the upper side are formed by forming a passage shape in which the convex portion 40 is provided in one of the passages (the lower passage 26 in FIG. 5). Unintentional disengagement can be prevented.

Further, as shown in FIG. 6, a continuous passage 42 having a series of slot shapes is formed, and narrow slots 42A and 42A and wide slots 42B and 42B are formed in two regions of the passage 42. You can also. At this time, in FIG. 6, when the convex portion 45 is formed in the region of the lower wide slot 42B and the lower second binding shaft 20 preferentially hits the convex portion 45, the upper side first By forming the two binding shafts 20 so as not to collide with the inner end 42C of the wide slot 42B, the disengagement of the first and second binding shafts 19 and 20 on the upper side can be prevented.
In addition, the structure made into a single channel | path is naturally applicable also to the channel | paths 25 and 26 in the said embodiment.
