[Problems to be solved by the invention]
However, as long as such a structure is used, due to the insertion of the fixture, it is necessary to secure a certain amount of play in the lateral hole of the protruding portion from the viewpoint of assembly and disassembly work. The dilemma that the fixing force of the binding becomes weak and the fixing state of the binding tool at the time of use becomes sweet cannot be wiped out. In particular, since the protruding portion needs to be within the range of the protruding amount that does not hinder binding, the inner diameter of the horizontal hole tends to be inevitably small, and the fixture must be a small-diameter linear shape. I don't get it. For this reason, there is a certain limit to the pursuit of the fixing force by the fixing tool.
[0006]
The present invention has been made paying attention to such a problem, and a file and a file structure in which a binding tool can be stably and reliably attached to a cover body without impairing a separable structure. The purpose is to provide a cover body.
[0007]
[Means for Solving the Problems]
In order to achieve this object, the present invention takes the following measures.
[0008]
That is, in the file of the present invention, when the binding tool is detachably attached to the cover body via the fixing means, the fixing means is engaged between the cover body and the binding tool so that the binding tool is orthogonal to the attaching / detaching direction. A restriction part that restricts displacement in the direction and a state that is restricted by the restriction part by directly engaging a part of the cover body in a direction perpendicular to the attaching / detaching direction in a part other than the restriction part. A pressing tool that selectively engages a part of a binding tool and prohibits displacement in the removal direction, and the binding tool is displaced in the removal direction at two locations in the vicinity of both ends in the longitudinal direction. One part is a part pressed by the presser, and the other part is a fixed presser having a downward surface set to a part of a cover body inserted in advance of the presser to the parts and the cover body And wherein the formed a portion to be inserted into the gap.
[0009]
In this way, since the pressing tool is not attached using a part of the restricting portion, the attachment structure can be adopted relatively freely without being restricted by the restricting portion. Since the presser is directly engaged with a part, for example, compared to a structure in which a protrusion that allows the presser to be engaged by penetrating the cover body and the binding tool from the backing, A sense of unity with the cover sheet is also increased, and thereby, the attachment state can be made more reliable and the fixing force to the binding tool can be increased. Therefore, it is possible to effectively increase the strength of the file without impairing the separable structure.
[0010]
As a structure for direct engagement, in addition to the case where a protruding part and a fixed holding part are integrally formed on a part of the cover body as described later, a protruding part and a fixed holding part which are formed separately on a part of the cover body are provided. There are those that are integrally attached through adhesion or welding.
[0011]
In particular, if the presser is externally fitted to a part of the cover body, the presser can be tightly fitted to the cover body over the necessary area, and the shape of the presser must be linear. Since there is no, it becomes possible to pursue the pressing force by the pressing tool relatively freely.
[0012]
As a simple embodiment of the restricting portion, there is one that forms a concave-convex engagement structure with a convex portion provided on either the cover body or the binding tool and a concave portion provided on the other side.
[0013]
In order to make the presser easy to attach and detach, the presser is externally fitted to the protruding part having the rail function provided in a part of the cover body so as to hold the protruding part using the rail function. It is effective to have a configuration to do so. Moreover, what has a click stop which a pressing tool elastically engages with a part of protrusion part can be mentioned.
[0014]
In order to effectively avoid an increase in the number of parts without impairing the proper attachment state of the binding tool, the binding tool is structured to prohibit displacement in the removal direction at two locations, and the presser is at one location. It is desirable to provide a portion to be inserted in advance as a fixed pressing portion having a downward surface set as a part of the cover body as another portion after the portion is pressed by the tool.
[0015]
In particular, the binding tool includes a base member that is attached to the attachment surface set on the cover body, and the base member includes a thick part in which a mechanical part such as an elastic body is incorporated, and a thin part adjacent to the thick part. When this is provided, it is possible to effectively use the dead space by setting the thin portion as a portion for engaging the pressing tool.
[0016]
When the effect that the binding tool can be reliably fixed to the cover body simply by separating the restricting portion and the pressing portion can be expected, the pressing portion may be used in such a manner that it is not directly engaged with a part of the cover body.
[0017]
In order to constitute the above file, it is preferable that the cover body is formed with a protruding portion having a rail function for externally fitting the presser. It is convenient for handling to attach a pressing tool to the protruding portion.
[0018]
In addition, by forming a fixed pressing portion having a downward surface for inserting a part of the binding tool in advance at a position different from the protruding portion, the number of pressing tools used can be effectively reduced. it can.
[0019]
In order to simplify the manufacturing process, it is desirable to form a cover body by integrally molding the front cover, back cover, and spine cover with resin, and at that time, it is desirable to make the protruding part and the fixed pressing part integrally. .
[0020]

[0033]
A procedure for assembling the file F configured as described above will be described with reference to FIGS.
[0034]
First, as shown in FIG. 4 which is a side view and FIG. 5 which is a partially enlarged view, one end 63b of the thin portion 63 of the base member 6 is placed on the downward surface 26b2 and the base attachment region 26a of the fixed pressing portion 26b. It inserts in the clearance gap S formed between the attachment surfaces 26 to which it belongs, and is made to contact | abut to the standing surface 26b3 (FIG. 5). Then, by rotating the base portion 6 with the contacted portion as a fulcrum, the through hole 63a and the convex portion 26a1 are engaged with each other and the other end 63c of the thin portion 63 is brought close to the upright surface 26c1 of the protruding portion 26c. Or contact. As a result, the positional deviation in the vertical and horizontal directions perpendicular to the attaching / detaching direction of the binding tool T is restricted, and the base member 6 is placed on the base attachment region 26a.
[0035]
Next, a procedure for fixing the base member 6 with the fixed slider 9 will be described with reference to FIGS. 6 and 7A, 7B, and 7C. 6 is a cross-sectional view taken along the line AA of FIG. 3. FIG. 7A shows a state where the fixed slider 9 is engaged with the protruding portion 26c, and FIG. FIG. 7C shows a state when the base member 6 is completely fixed by the fixed slider 9.
[0036]
First, the first opening 91 of the fixed slider 9 is inserted into the tip end portion 26c2 of the protruding portion 26c using the fixed slider 9 (FIG. 7A). From that position, the rail portion 26c4 is sandwiched between the elastically deformable click stop 96 and the protrusion 93a (FIG. 6), and the fixed slider 9 is slid toward the convex portion 26a1 (FIG. 7B). Meanwhile, the click stop 96 is slid while being elastically deformed slightly upward by contacting the protrusion 26c. When the pressing piece 94a is slid to a position exceeding the convex portion 26a1, the thin portion 63 of the base member 6 is pressed by the lower surface 94a2 of the pressing piece 94a (FIG. 7C). At this time, the click stop 96 is elastically restored and engaged with the wall surface of the protruding portion 26c. Thereby, the displacement of the base member 6 in the removal direction is prohibited, and the fixing of the cover body 1 and the base member 6 is completed.
[0037]
Then, after attaching the pressing pieces 7 and 8 to the pair of side edges 61 and 61 of the base member 6 attached in this way from above, the front cover 3 and the back cover 4 are bent at right angles to the spine 2. The assembly of the file F is completed by engaging the elastic deformation portions 31 and 41 with the pressing pieces 7 and 8.
[0038]
As described above, the file F of the present embodiment relates the fixing means Y between the cover body 1 and the binding tool T when the binding tool T is detachably attached to the cover body 1 via the fixing means Y. A restriction part Z that restricts the binding tool T from being displaced in a direction perpendicular to the attaching / detaching direction, and a restriction part that is directly fitted on a part of the cover body 1 at a portion other than the restriction part Z. A fixed slider 9 that selectively engages with a part of the binding tool T in a state restricted by Z and prohibits displacement in the removal direction is provided.
[0039]
If constituted in this way, since the fixed slider 9 is not attached using a part of the restricting portion Z, a relatively free structure can be adopted without being restricted by the restricting portion Z in terms of space. The fixed slider 9 can be tightly fitted over a necessary area because it is directly engaged with a part of the body 1 and is externally fitted. Therefore, the pressing force by the fixed slider 9 can be pursued relatively freely, and the strength of the file F can be effectively increased without impairing the separable structure.
[0040]
In particular, as compared with the conventional structure in which the cover body 1 and the binding tool T are penetrated from the backing and a claw or the like for engaging the presser is disposed, the fixed slider 9 and the cover body 1 are The experience can also be increased and the mounting state can be made more reliable.
[0041]
Further, since the restricting portion Z is configured through the concave / convex engaging structure X formed by the convex portion 26a1 provided on the cover body 1 and the through hole 63a provided on the binding tool T, the restricting portion Z is formed by a structurally simple method. Can be realized. In the present embodiment, apart from the concave and convex engagement structure X described above, one end 63b of the base member 6 and the upstanding surface 26b3, and the other end 63c of the base member 6 and the upstanding surface 26c1 are respectively It can be said that the function of the restricting portion Z is assisted by the contact.
[0042]
Further, a configuration is adopted in which the fixed slider 9 is externally fitted to the protruding portion 26c having the rail portion 26c4 provided on a part of the cover body 1 so as to hold the protruding portion 26c using the rail function. Therefore, the fixed slider 9 can be easily attached and detached and the operation is stable.
[0043]
Further, the binding tool T has a structure that prohibits displacement in the removal direction at two locations, and one location is a portion pressed by the fixed slider 9 (the thin portion 63 on the other tip 63c side of the base member 6). In addition, the gap S that is inserted in advance at the fixed pressing portion 26b having the downward surface 26b2 formed in a part of the cover body 1 at another portion (the thin portion 63 on the one end 63b side of the base member 6). Therefore, the increase in the number of parts can be effectively avoided by reducing the number of the fixed sliders 9 to the necessary minimum without impairing the proper mounting state of the binding tool T. Further, the cost can be reduced. be able to.
[0044]
In particular, in the binding tool T of this embodiment, the base member 6 attached to the attachment surface 26 set on the cover body 1 includes a thick part 62 in which a mechanical part 62a such as an elastic body is incorporated, and the thick part 62. In the present embodiment, the thin portion 63 is fixed to the fixed slider 9 or the fixed holding portion, although the space above the thin portion 63 is a dead space. Since the dead space is effectively used, it is possible to effectively avoid inconveniences such as part of the file F becoming bulky by adopting the structure of the present invention. Become.
[0045]
On the other hand, the cover body 1 for realizing the above-mentioned file F may be formed with a protruding portion 26c having a rail function for fitting the fixed slider 9 in a part thereof, and fixed to the protruding portion 26c. It is convenient in handling that the slider 9 is attached, and the loss of the fixed slider 9 can be prevented.
[0046]
Further, the number of the fixed sliders 9 used can be reduced simply by forming the fixed pressing portion 26b having the downward surface 26b2 for inserting a part of the binding tool T in advance at a position different from the protruding portion 26c of the cover body 1. It can be reduced and can contribute to cost reduction.
[0047]
Further, the front cover 3, the back cover 4 and the back cover 2 are integrally formed of resin to form the cover body 1, and at this time, the protruding portion 26 c and the fixed pressing portion 26 b are integrally formed. Simplification of the entire manufacturing process can be achieved.
[0048]
The present invention is not limited to the above embodiment.
[0049]
For example, in the above-described embodiment, the restricting portion Z is configured by the protruding portions 26c provided at two places in the width direction and the fixed pressing portions 26b, but the number of the protruding portions 26c and the width of the spine cover 2 are Even if the width dimension is increased or decreased, the same effects as those of the above embodiment can be obtained.
[0050]
As a minimum configuration, the restricting portion Z can be configured only by providing one set of the protruding portion 26 c and the fixed pressing portion 26 b regardless of the width dimension of the spine cover 2.
[0051]
Furthermore, in the said embodiment, although the control part Z employ | adopts the uneven | corrugated engagement structure which consists of the convex part 26a1 provided in the cover body 1, and the through-hole 63a which is a recessed part provided in the binding tool T, conversely Alternatively, a concave portion such as a through-hole may be provided on the cover body 1 side, and a convex portion may be provided on the binding tool T side.
