Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a file mainly composed of a resin in which a file body and a binding tool are separable from each other.

[0002]

2. Description of the Related Art Conventionally, as a file represented by a tube file, a binding tool having a pair of paper pressing members and a binding rod projecting from the paper pressing members and fitted with each other, and the binding tool is held on a spine cover. There is known one having a holding base for making it.

In this type of file, one paper pressing member is rotatably supported by the holding base, while the other paper pressing member is rotatably supported by the holding base. There is known a typical one in which the other paper pressing member is detached from the holding base and one paper pressing member is rotated, and then the fitting of the binding rod is released.

Recently, an elastically deformable engaging claw is provided integrally with the holding base, and the engaged claw is engaged with the engaged claw provided on the sheet pressing member.
While holding the sheet pressing member rotatably, the engaging claw is elastically deformed to the non-engaging position to release the engagement with the engaged claw, and the sheet pressing member can be detached from the holding base. Things that have been done are also being developed.

[0005]

However, in the conventional case, the holding base and the file body are separate bodies, so that the assembly and manufacturing steps may be complicated. Further, in the case of elastically deforming the engaging claws, a load such as a document directly acts on the engaging claws via the binding tool, so that fatigue of the member applied to the engaging claws easily occurs, and If the elastic return force of the engaging claw is weakened even a little, the problem that the binding tool is likely to come off may occur.

Therefore, the present invention is intended to provide a resin file which can reduce the number of parts as much as possible without impairing the reliability of document holding.

[0007]

That is, a file according to the present invention is provided between a file body and a binding tool for binding documents so that a part or all of the binding tool can be rotated on the file body. Mainly made of a resin provided with a hinge device for holding it separably,
The hinge device includes a holding base provided on the file body, an engaged body movably held by the holding base between an engaging position and a non-engaging position, and the holding base held by the holding base. An elastic member that urges the engaging body to the engaging position and an engaging body that engages with the engaged body that is provided in the binding tool and that is in the engaging position and that rotatably supports the binding tool around a predetermined axis. The holding base is integrally formed with the file body, and the engaged body and the elastic member are incorporated separately from the holding base.

In this case, since the holding base is formed integrally with the file body, it is possible to reduce the number of parts and to facilitate the assembling and manufacturing process accordingly. Become.

Concretely, there may be mentioned one in which the engaged body is a shaft member having a shaft shape.

In order to reduce the number of parts without impairing usability, an operating member for moving the engaged body against the urging force of the elastic member is further provided, and the operating member is integrated with the engaged body. It is preferable that it is molded.

Further, in order to further reduce the number of parts, it is conceivable to integrally form the engaging body with the binding tool.

As a specific embodiment for realizing the double-opening, the binding tool includes a pair of sheet pressing members and a binding rod projecting from the sheet pressing members and fitted to each other. It is preferable that each member is provided with an engaging body and the holding base holds an engaged body corresponding to each member.

A preferred embodiment in terms of load support is one in which the direction of movement of the engaged body is configured to be substantially orthogonal to the load acting on the binding tool. With such a structure, the elastic member can be configured so as not to receive a direct load from the engaged body, so that the elastic member is less likely to be fatigued, and the fatigue is caused to recover elastically. This is because it is possible to avoid the problem that the binding tool is likely to come off even if the force is weakened.

In a preferred embodiment of the elastic member, the elastic member has a partially arcuate shape in plan view, its central portion is pressed against the engaged body, and both end portions are pressed against the pressure receiving surface provided on the holding base. An example is a device that urges the engaged body toward the engagement position.

As shown in FIG. 1, the file according to this embodiment has a file body 1, a binding tool 2 for binding a document, and the file body 1 and the binding tool 2 which are separably and rotatably combined. And a hinge device 3 that operates.

The file body 1 is made of, for example, a front cover 11, a back cover 12, and a back cover 13 which are integrally formed. The thickness of the connecting portion between the cover sheets is made smaller than the other portions, The part has a bendable hinge function. In FIG. 1, the front cover 11 and the back cover 13
Have been omitted. Of course, the spine cover 12, the front cover 11 and the back cover 13 may be separate bodies.

As shown in FIG. 1, the binding device 2 has a pair of rectangular plate-shaped sheet pressing members 21 and 22, and vertically protrudes from the face plate portions of the sheet pressing members 21 and 22, and the width of the spine cover 12. It is composed of a plurality of binding rods 23, 24 having a length dimension corresponding to the dimension. The paper pressing members 21 and 22 are attached to the back surface of the spine cover 12 so that one long side of the back cover 12 faces the center of the back side of the spine cover 12. A notch 2a is formed for hooking the sheet holding members 21 and 22 to lift them. Further, among the binding rods 23 and 24, one that projects from one sheet pressing member 21 has a cylindrical shape, and one that projects from the other sheet pressing member 22 fits into the inner circumference of the corresponding binding rod 23. It has a rod shape.

The hinge device 3 is made of resin and has a holding base B formed integrally with the spine cover 12 of the file body 1 and an engaging position (shown by a solid line in FIG. 2) on the holding base B. A shaft member 51 that is movably held between a non-engaging position (shown by an imaginary line in FIG. 2) and a shaft member 51 that is provided in the binding device 2 and is in the engagement position engages with this binding device. And an engagement body 52 that rotatably supports the shaft 2 around the shaft member 51. In this configuration, the paper pressing members 21 and 22 are in a posture that is substantially vertical to the spine cover 12 and that is a posture for holding documents, and a posture that is substantially parallel to the spine cover 12 and that is for storing documents. It is rotatably held between the document withdrawal / injection posture Q, which is an injectable / removable posture.

The elastic member 7 has a partially arcuate shape in a plan view, its central portion is coupled to the operating member 6, and both ends thereof are in contact with the pressure receiving surface of the partition plate B3 vertically provided at the center of the holding base B. I am letting you. When a pressing force is applied to the operating member 6 or the shaft member 51 from the outside to move them toward the non-engagement position set inward, the operating member 6 or the shaft member 51 is flattened, and when the pressing force disappears, the elastic returning force causes the operating member to move. 6 and the shaft member 51 are urged outward so that the shaft member 51 is located at the engagement position where it contacts the inner surface of the side plate of the holding base B. The pair of protrusions B4 protruding from the partition plate B3 are stoppers for restricting the flatness of the elastic member 7.

In addition, in this embodiment, a guide mechanism 8 is provided for restricting the movement of the shaft member 51 and the operation member 6 that moves in synchronization with the shaft member 51 so that the movement is orthogonal to the axial direction. The guide mechanism 8 is provided on the guide ridge 81 that integrally projects from the back surface of the top plate of the holding base B and extends in the direction orthogonal to the axial direction, the shaft member 51 (operation member 6) and the elastic member 7, and the guide protrusion 8 is provided. The guide groove 82 slidably fits into the strip 81.

Further, in order to prevent the shaft member 51, the operating member 6 and the like from moving up and down, a pair of horizontal members B5 extending in the direction orthogonal to the axis L are provided in the lower surface opening of the holding base B, It has been bridged together.

On the other hand, the engaging body 5 engaging with the shaft member 51.
Reference numeral 2 denotes a claw-shaped member that integrally extends from both ends of the long sides of the sheet pressing members 21 and 22 and slightly toward the center. In the binding posture, a claw base that covers the outside of the shaft member 51 through the engagement window B1. An end portion 521 and a claw tip portion 522 that integrally extends inward from the tip of the claw base end portion 1 and covers the shaft member 51 from below (from the spine cover 12 side). The inner surface thereof is curved so as to follow the outer surface 51a of the shaft member 51.

Further, the hinge device 3 according to the present embodiment.
Further includes an auxiliary rotation guide portion 4 set outside the holding base B in the axial direction. This auxiliary rotation guide 4
Supplements the engagement between the shaft member 51 and the engaging body 52, and restricts the paper pressing members 21 and 22 so that they can rotate only around the shaft member 51.

As shown in FIG. 1 and FIG. 5, the auxiliary rotation guide portion 4 has a pair extending axially from the holding base B so as to be symmetrical with respect to the central transverse line of the holding base B. Ridge 41 and the paper pressing members 21, 22
And a pair of guided members 42 that are integrally formed at both ends of the long side portion. In this embodiment,
The auxiliary rotation guide portion 4 is connected to the sheet pressing members 21, 2
Corresponding to 2, two pairs are provided symmetrically on the left and right.

The tip of the protrusion 41 is a shaft member 51.
It is formed into a round shape so as to form a concentric semi-cylindrical shape, and a guide surface 41a is formed on the tip end surface thereof.

The guided member 42 is integrally bent and extended outward from the long side portions of the paper pressing members 21 and 22, and is in contact with the guide surface 41a of the protrusion 41 in the binding posture P. The end portion 421 and the base end portion 42
It is provided with a tip portion 422 which is bent from 1 and extends substantially in parallel with the paper pressing members 21 and 22, and which is in contact with the inner side surface of the ridge 41. The corner portions of the base end portion 421 and the tip end portion 422 serve as a guided surface 42a that is guided by the guide surface 41a of the ridge 41 and rotates the sheet pressing members 21 and 22 around the axis.

Then, the binding posture P and the document input / output posture Q
Between the guide surface 41a and the guided surface 42a of the auxiliary rotation guide portion 4 with respect to the engaging portion of the engaging body 52 and the shaft member 51, the axis L The auxiliary rotation guide portion 4 complements the engagement between the engaging body 52 and the shaft member 51 by setting the components so as to be substantially opposed to each other with the component sandwiching the sheet pressing members 21 and 22 orthogonal to the axial direction. It is configured to prevent movement in any direction including.

However, as described above, the shaft member 51
And operation member 6 and elastic member 7 provided integrally therewith
Is a separate body from the holding base B and the file body 1, and is made of different resins. The shaft member 51 and the like are held in the internal space of the holding base B so as to be slidable only, and can be separated from the holding base B and the like only if they are destroyed. In this embodiment, these two members are molded in a mold by using a two-color molding method. Specifically, first, an integrally molded product including the shaft member 51 is molded by injecting resin from one injection port of the mold, and then the holding base B
Is molded by injecting another resin, which is not welded to the resin, from another injection port by moving the one-piece molded product including the above by rotating the mold.

How to use the file and the movement of the hinge device 3 according to the present embodiment configured as described above will be described below.

First, in order to attach the binding tool 2 to the spine cover 12, the binding tool 2 is placed in the binding posture P, and the tip of the engaging body 52 is slid down while coming into contact with the corresponding shaft member 51, while the binding tool 2 is attached to the spine cover 12. Get closer. When further pushed in, the engagement body 52 contacts the outer side surface 51a of the shaft member 51 and urges it inward, so that the shaft member 51 reaches the inner non-engagement position (shown by an imaginary line in FIG. 2). To move. At this time, the engaging member 52 receives a reaction force to displace it from the shaft member 51 to the outside.
Due to the contact with 2, the displacement is prohibited and the engaging body 52 is not separated from the shaft member 51. When the guided surface 42a comes into contact with the guide surface 41a and reaches a position where the guided surface 42a cannot be further pushed in, the shaft member 51 returns to the engagement position (shown by the solid line in FIG. 2) due to the elastic restoring force of the elastic member 7.
Engage with the engagement body 52.

In this state, the paper pressing members 21 and 22 are
Due to the engagement between the engaging body 52 and the shaft member 51, the engaging body 52 and the shaft member 51 cannot move inward and upward (opposite to the spine cover 12 side), and the protrusion 4
Due to the contact between 1 and the guided member 42, it is in a state where it cannot move outward and downward (on the back cover 12 side). That is, the paper pressing members 21 and 22 have the guide surface 41.
a and the guided surface 42a are in contact with each other, and the engaging body 5
When the shaft member 51 is sandwiched and substantially opposed to each other, the engaging portion of the shaft member 51 and the shaft member 51 are restrained from moving in any direction including a component orthogonal to the axial direction.

On the other hand, the sheet pressing members 21 and 22 can rotate from the binding posture P toward the front cover 11 or the back cover 13 as a single unit, and at that time, as shown in FIGS. As described above, the guided surface 42a is guided by the guide surface 41a, while the inner surface of the engaging body 52 is guided by the outer peripheral surface of the shaft member 51 to rotate about the axis L. Further, even between the binding posture P and the document insertion / removal posture Q, the guide surface 41a and the guided surface 42 depend on the angles.
The sheet contacting members 21 and 22 are orthogonal to the axial direction because the portion that comes into contact with a and the portion that the engaging body 52 and the shaft member 51 engage with each other with the shaft member 51 interposed therebetween are substantially opposed to each other. It is constrained so that it cannot move in any direction including the component.

To remove the paper pressing members 21 and 22 attached to the spine cover 12, the paper pressing member 2 is used.
With the binding positions 1 and 22 in the binding posture P, the operation portion is pressed from the outer side to the inner side. In the binding posture P, as shown in FIG. 2, the engagement surfaces of the shaft member 51 and the engagement body 52 are vertically overlapped with each other, and the inward movement of the shaft member 51 is allowed. By operating the part 6,
The engagement is released, and the paper pressing members 21 and 22 can be removed from the spine cover 12. It should be noted that, in a posture other than the binding posture P, the claw tip portion of the engaging body 52 engages with the inner side surface of the shaft member 51, and even if the operating portion is pressed, the inward movement of the shaft member 51 is prohibited. , You cannot cancel the relationship.

Therefore, according to the present embodiment having such a configuration, since the holding base B is integrally formed with the file body 1, the number of parts can be reduced and the assembly and manufacturing steps can be simplified accordingly. Be able to promote. Further, most of the load acting on the shaft member 51 is supported by the side plate and the bottom plate of the holding base B, and the elastic member 7 receives almost no direct load via the shaft member 51. It is possible to avoid the problem that the member 7 is less likely to be fatigued and that the binding tool 2 is likely to come off even if the fatigue is caused and the elastic return force is weakened.
Further, since the shaft member 51 moves in a direction substantially orthogonal to the load direction, particularly in the present embodiment, in the binding posture, the engaging body 52 engages with the surface of the shaft member 51 on the spine cover side, and the engaging surface is Since the surface including the surface orthogonal to the direction in which the load acts is included, the binding tool 2 is reliably held.

In addition, in this embodiment, when the binding tool 2 is separated and connected, the elastic member 7 needs to be elastically deformed, but there is no part to be deformed when it is rotated. The structure is less stressful and has excellent durability and holding power, etc., as compared with a hinge operation utilizing the property.

The present invention is not limited to the above embodiment.

For example, the hinge device may be applied to only one of the sheet pressing members.

The engaging body, the guide surface and the like are not limited to a pair and may be provided in three or more, but it is preferable to provide two or more, one of which is spaced apart on the same axis line, and the other is positioned so as to be sandwiched between them. Is good.

Others The present invention is not limited to the above illustrated examples,
It goes without saying that various modifications can be made without departing from the spirit of the invention.
