Description

The present invention relates to a file, more particularly, while the combined relates the distal end side of the first and second binding member having an axial forming a closed loop, the mutual dependency of the first and second binding members The present invention relates to a file in which a binding tool capable of adding and removing documents by releasing and closing a closed loop is integrated with a cover body.

  A binding tool used for a ring file or the like includes a base having a predetermined length along the longitudinal direction of the back cover of the file, and a first binding member positioned at one end in the width direction of the base at two positions in the longitudinal direction of the base. The second binding member is located on the opposite side of the first binding member and is provided so as to be engaged with the front end portion of the first binding member. The first and second binding members are supported so that the base side thereof is rotatable in the base, whereby the first binding member and the second binding member are in a closed loop forming position where the leading ends are engaged. And a closed loop opening position for releasing the engagement.

  Patent Document 1 discloses a binding tool including first and second binding members having a shaft shape called a half-cotton having a substantially semicircular shape, and the distal ends of the first and second binding members. A substantially circular closed loop can be formed in a state where the two are engaged with each other, and a configuration is employed in which the closed loop is opened by releasing the engagement.

JP 2006-159913 A

However, in the known binding tool and the binding tool described in Patent Document 1, the first and second binding members are in a closed loop forming position and form a substantially circular ring shape. This tends to increase the size. For example, when a large number of documents are stacked and bound to a thickness of about 22 mm, the inner diameter of the ring by the first and second binding members is about 30 mm, and the outer diameter is about 30 mm considering the strength shaft diameter of the ring. It may be designed to be about 36 mm. In this case, there is an inconvenience that the inside width of the back cover of the file forming the fixing surface of the binding tool is required to be about 36 mm, and it is difficult to make a thin file smaller than that.
In this case, as in the file described in Patent Document 1, a long hole is provided in the front cover and the back cover so that a part of the first and second binding members can be received, and each cover is substantially parallel. Although the thickness dimension at the time of binding can be suppressed, when the spine cover width is set to be smaller than the ring outer peripheral diameter, a part of the first and second binding members protrude beyond the outer surface of the cover. This will cause the inconvenience. Therefore, in order to prevent a part of the first and second binding members from protruding from the outer surface of the cover, the width of the spine must be designed to be large to a certain limit.
In addition, the anti-binding side edge of a large number of documents bound to the binding tool has a large chevron when viewed from the side in a state in which the protruding amount of the document located in the middle of the document thickness direction is maximized. This makes it difficult to turn the fingertip on the side edge and make it difficult to turn the document.

[Object of the invention]
The present invention has been devised by paying attention to such inconveniences, and the object thereof is to suppress the dimension along the width direction when the first and second binding members are in the closed loop forming position. It is to provide a can Ru file.

  Embodiments of the present invention will be described below with reference to the drawings.

[First Embodiment]
FIG. 1 shows a schematic perspective view of a main part when the binding tool according to the first embodiment is applied to a file, and FIG. 2 shows an enlarged perspective view of the binding tool. 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 attached to the inner surface of the spine cover 11. Has been. Here, in the surface of the front cover 12 and the back cover 13 near the spine cover 11, elongated holes 12A and 13A for receiving a part of the binding tool 15 are formed linearly along the width direction of each cover. Yes.

  The binding tool 15 extends in the vertical (longitudinal) direction of the spine cover 11 and is fixed to the inner surface of the spine cover 11 via rivets 17 and 17, and an end of the base 18 on the front cover 12 side. A pair of first binding members 19 and 19 supported by the respective parts, and an end portion of the base 18 on the back cover 13 side, and are engaged with the respective front end portions of the first binding members 19 and 19. And a pair of second binding members 20 and 20 that form a closed loop together with the base 18. Here, each member which comprises the binding tool 15 is comprised using metal materials, such as stainless steel.

  As shown in FIGS. 3 to 5, the base 18 has a curved shape with a central portion in the width direction having a maximum height, and is provided in a lower open type. Both ends of the base 18 in the longitudinal direction are stepped to be formed as fixing portions 21 and 21 to the spine 11, respectively, and rivet holes 22 and 22 (see FIG. Reference) is formed. Further, four long holes 24 through which the base portions of the first and second binding members 19 and 20 pass are formed on both sides along the short width direction at two locations in the longitudinal direction of the base 18. Each of the long holes 24 is formed from the vicinity of the central portion in the short width direction of the base 18 to the side end portions in the width direction, thereby allowing the first and second binding members 19 and 20 to rotate. It has come to be.

The first binding member 19 and the second binding member 20 are formed in a symmetrical shape as shown in FIGS. 3 and 4. Therefore, in the following description, the 1st binding member 19 shall be demonstrated, the 2nd binding member 20 shall use the same code | symbol, and description of the said 2nd binding member 20 is abbreviate | omitted.
The first binding member 19 is formed using a round bar-shaped shaft member, a base 31 connected to a connecting plate 30 located in the base 18, an upright shaft 32 connected to the base 31, It consists of a curved shaft portion 33 that continues to the upright shaft portion 32. The base portion 31 forms a region between the connecting plate 30 and the lower end of the upright shaft portion 32, and in the state shown in FIG. 3, that is, in the closed loop forming position where the tip ends of the first and second binding members 1920 are engaged. It extends obliquely outward from the upper surface of the base 18 and is directed upward. The length L1 between the upper end of the base portion 31, that is, the boundary with the upright shaft portion 32 and the lower end of the base 18 is 10 mm.
The length L2 of the upright shaft portion 32 is set to 14 mm, the length L3 of the curved shaft portion 33 at the closed loop formation position is set to 10.7 mm, and the length L from the inner surface to the upper end of the spine cover 11 is set. Is set to 34.7 mm.
The curved shaft portion 33 includes an arc-shaped portion having an inner peripheral radius R of 11 mm, and a tip region thereof is formed to have a substantially horizontal posture.
Furthermore, in the closed loop forming position, the maximum width W1 of the first and second binding members 19 and 20 is 30 mm, and the inner peripheral side width W2 is 24.6 mm.
The width W3 of the spine cover 11 is 28 mm. The width W3 of the spine cover 11 referred to here is used for the distance between the inner surfaces of the front and back covers 12 and 13 when they are parallel.

  The first and second binding members 19 and 20 maintain a closed loop formation position (see FIG. 3) via a structure in which their distal ends are engaged with each other, and by releasing the engagement, a closed loop open position (FIG. 4) is obtained. See). That is, although the detailed structure is omitted here, the connecting plates 30 in the base 18 are combined with each other via a spring in a state where the relative angle is displaceable. A known structure is employed in which the direction of the force in the rotational direction of the first and second binding members 19 and 20 can be switched by the displacement.

The document P bound by using the binding tool 15 in the first embodiment can be viewed as, for example, the posture shown in FIG. This figure shows an example in which a large number of documents P are stacked to have a thickness of about 22 mm. As is clear from this figure, the binding side edge P1 and the outer side edge P2 serving as the anti-binding side edge of the document P are slightly curved, but in the vertical direction due to the presence of the linear upright shaft portion 32. Keep in line. Therefore, it is possible to easily turn the document P by easily hooking the fingertip on the outer edge P2.
Further, when the document P in which a binding hole is formed with a hole diameter by a commercially available punch is moved or turned as a whole, the inner peripheral radius of the curved shaft portion 33 is shown in FIG. Is set to 11 mm, the frictional resistance with the binding hole of the document P does not become excessive, and the movement of the document P along the first and second binding members 19 and 20 may be hindered. Absent.
Further, as shown in FIG. 5C, when the cover body 14 is closed so that the front cover 12 and the back cover 13 are substantially parallel to each other, the upright shaft portion 32 has the long holes 12A, 13A. The central portion of the outer edge P2 of the document P does not protrude outward from the free end of the cover body 14, and thus the width dimension of the front and back covers 12, 13 is increased. There is no need. That is, when the size of the document P is assumed to be A4 or B5, a commercially available file cover having a cover width suitable for binding of A4 or B5 size paper can be used.

[Second Embodiment]
Next, a second embodiment of the present invention will be described with reference to FIGS. In the following description, the same reference numerals are used for the same or equivalent parts as in the first embodiment, and the description is omitted or simplified as necessary.

The second embodiment is characterized in that the upright shaft portion 32 is provided in an arc shape having an inner peripheral radius of 25 mm and is connected to the curved shaft portion 33 having an inner peripheral radius of 11 mm. Have Therefore, in the second embodiment, at the closed loop forming position, the maximum width W1 of the first and second binding members 19 and 20 is set to 31.4 mm, the inner circumferential width W2 is 26 mm, and the total length L is 34.mm. It is set to 7 mm. The width W3 of the spine cover 11 is 29.4 mm. In the second embodiment, since the standing shaft portion 32 is not linear, the boundary between the base portion 32 and the curved shaft portion 33 cannot be clearly distinguished, but here, for convenience in understanding the embodiment, The dimensions L1, L2, and L3 corresponding to the embodiment are 10 mm, 14 mm, and 10.7 mm, respectively.
Other configurations are substantially the same as those in the first embodiment.

  In such a 2nd embodiment, the operation and effect substantially the same as binding tool 15 of a 1st embodiment can be acquired only by becoming somewhat larger than binding tool 15 in a 1st embodiment.

As described above, the best configuration, method and the like for carrying out the present invention have been disclosed in the above description, but the present invention is not limited to this.
That is, although the present invention has been illustrated and described with particular reference to particular embodiments, it is not intended to depart from the technical concept and scope of the invention. Those skilled in the art can make various changes in terms of material, quantity, position or arrangement.
Accordingly, the description of the limitation on the shape and the like already disclosed is an example for facilitating the understanding of the present invention and does not limit the present invention. The description by the name of the member which remove | excluded one part or all part is included in this invention.

  For example, in the above-described embodiment, a case where the maximum thickness of 22 mm is obtained by superimposing a large number of documents P has been described so that the operation of the document P can be performed smoothly, but the maximum thickness is further increased. Alternatively, in the case where the size is reduced, that is, when the number of sheets that can be bound is increased or decreased to be adaptable, the first and second binding members 19 and 20 are provided in a similar shape or the like.

  Moreover, although the two 1st and 2nd binding members 19 and 20 in the said embodiment were each provided, it does not prevent increasing.
