Description

The present invention relates to a clear file having a binding hole and a binder capable of stacking and binding a plurality of clear files.

Ring-type binders that stack and bind multiple clear files are frequently used in normal office work, etc., and are mainly intended for indoor use. However, ring-type binders often file necessary documents for the purpose of outdoor use such as musical scores for outdoor performances and blueprints used at construction sites.

When using outdoors, clear files can easily be rolled up even by a slight wind. In calm times when there is no wind and the wind speed is 0.2 m / s or less, there is usually some wind, so the problem of clear file curling should be assumed almost all the time. Also, even if you do not usually feel the wind, a gust of wind may blow for a moment.

In order to solve this problem, Patent Document 1 describes an invention in which surface fasteners are used at the four corners of the clear file to prevent the clear file from curling. However, in the invention described in Patent Document 1, it is not possible to prevent the surface of the clear file from waving due to the wind, and there remains a problem that the document filed in the clear file becomes difficult to see. It is said that the wind speed that the human body consciously feels is 1.6 m / s or more, but even if it is less than 1.6 m / s, the surface of the clear file will undulate. In addition, since a hook-and-loop fastener is used, it is necessary to peel off the hook-and-loop fastener between a plurality of clear files in order to turn to the next page, which is very troublesome and time-consuming. Further, both hands must be used to remove the hook-and-loop fastener, which is very disadvantageous in a situation where, for example, a page must be turned instantly with one hand at a concert.

Hereinafter, the first to tenth embodiments of the present invention will be described with reference to the drawings. In the description of the drawings below, the same or similar parts are designated by the same or similar reference numerals. However, it should be noted that the drawings are schematic, and the relationship between the thickness and the plane dimension, the ratio of the thickness of each layer, etc. are different from the actual ones. In particular, all of the sheets and films appearing in the present specification are actually on the order of millimeters or less, but it is difficult to express the thickness when illustrated at an actual scale, so the thickness is exaggerated. It may be how to draw. Therefore, the specific thickness and dimensions should be determined in consideration of the following explanation. In addition, it goes without saying that the drawings include parts having different dimensional relationships and ratios from each other.

Further, "front surface" and "back surface", "up and down" and "left and right" or "up and down direction" and "lateral direction" in the present specification are expedient expressions based on a fixed viewpoint in the illustration. It is not an expression that limits the usage pattern. For example, in the structure according to the first to tenth embodiments of the present invention, the user may use the structure with the "back surface" facing the front side and the "front surface" facing the back side. In that case, it goes without saying that the right and left of "left and right" are also exchanged. The same idea applies to "up and down" and the like.

Further, the first to tenth embodiments of the present invention shown below exemplify the structure and usage of an object for embodying the technical idea of the present invention, and the technical idea of the present invention. Does not specify the material, shape, structure, arrangement, etc. of the component parts to the following. The technical idea of the present invention may be modified in various ways within the technical scope specified by the claims stated in the claims.

(First Embodiment)
As shown in FIG. 1, the clear file 1a according to the first embodiment of the present invention includes a hard and transparent surface sheet portion 3a and a second upper portion connected to a first upper portion defined in the surface sheet portion 3a. And the back sheet portion 3b having the second lower portion connected to the first lower portion defined in the front surface sheet portion 3a constitutes a rectangular bag-shaped pocket portion (3a, 3b) having an opening portion 15a on one side. Further, it is provided with a film-shaped binding margin 5a connected to the back sheet portion 3b and having a plurality of binding holes 7a _{1 to 7a 30} in a row in the vertical direction, but the binding margin 5a is from the front sheet portion 3a. Is also thin. In the clear file 1a according to the first embodiment, an opening for inserting a filing object such as a document in the vicinity of the binding margin portion 5a at the end portion of the front surface sheet portion 3a and the end portion of the back surface sheet portion 3b facing each other. The unit 15a is set.

As shown in FIG. 1, the surface sheet portion 3a is a flat plate-like member having a rectangular first main surface and a second main surface facing each other and exhibiting rigidity and weight (weight stoneness) at a certain thickness. The back sheet portion 3b in FIG. 1 has the same shape as the front sheet portion 3a, has a rectangular third main surface facing the second main surface, and has a fourth main surface facing the third main surface, and has rigidity. It is a flat plate-like member having a predetermined thickness and exhibiting a weight. As shown in FIG. 3, the first upper portion of the second main surface of the front sheet portion 3a and the second upper portion of the third main surface of the back sheet portion 3b facing the first upper portion are connected to each other at the upper connecting portion 11a. It is connected and fixed. Similarly, the first lower portion of the second main surface of the surface sheet portion 3a and the second lower portion of the third main surface of the back sheet portion 3b facing the first lower portion are connected and fixed to each other. In FIGS. 1 to 3 and the like, only the upper connecting portion 11a is shown, but it is possible that there is a lower connecting portion similar to the upper connecting portion 11a in each lower portion of the front sheet portion 3a and the back sheet portion 3b. Of course.

The upper connecting portion 11a of the front sheet portion 3a and the back sheet portion 3b shown in FIG. 1 may be strong enough not to be disconnected even in the open state of FIG. The opening 15a may have a sufficient space for the filing object when the filing object such as a document is inserted from the opening 15a and the filing object is put into the usage state as shown in FIG. The upper connecting portion 11a of the front sheet portion 3a and the back sheet portion 3b shown in FIG. 2 may be an adhesive or an adhesive tape. In the vicinity of the upper end portions of the front surface sheet portion 3a and the back sheet portion 3b in FIG. 2, the upper connecting portion 11a is shown as a planar glue margin region having a constant width in the vertical direction. Not too much. The upper connecting portion 11a may be linear with almost no width. The connection method is not limited to adhesion, and may be welding or crimping, or the front sheet portion 3a and the back sheet portion 3b may be formed by integral molding in the first place. One plate may be bent to form the front sheet portion 3a and the back sheet portion 3b.

Since the structure shown in FIG. 1 is an example, the connection between the front sheet portion 3a and the back sheet portion 3b is such that the upper connecting portion (first connecting portion) 11a on the upper side and the lower connecting portion (second) on the first lower portion are connected to each other. It is not limited to the case of only the connection part). In FIG. 1, an opening 15a is formed on the right side of the front sheet portion 3a and the back sheet portion 3b, but a third connecting portion is provided on the side facing the opening 15a, that is, on the left side of FIG. It may have been. When the third connection portion is provided, the front sheet portion 3a and the back sheet portion 3b form a rectangular bag shape with one side of the rectangle closed as an opening at the first to third connection portions, and the other. An opening 15a will be provided on one side.

The material of the front sheet portion 3a and the back sheet portion 3b is a transparent hard plastic so that the pocket portion (3a, 3b) does not roll up due to the wind and the surface of the pocket portion (3a, 3b) does not undulate. Is preferable. The hard plastic preferably contains acrylic (PMMA), polyvinyl chloride (PVC), polyethylene terephthalate (PET) or the like as a main material, and has a bending strength of about 70 to 130 MPa or more. If a hard plastic having a bending strength of about 70 to 130 MPa is used, the front sheet portion 3a and the back sheet portion 3b can exhibit desired rigidity with a thickness of 0.3 to 2.0 mm. In order to increase the rigidity of the pocket portions (3a, 3b), it may be a hard plastic containing a certain amount of glass fiber. For example, the bending strength of PET containing about 30% of glass fiber is strengthened to about 200 to 250 MPa. Since the bending strength of the rectangular cross section is proportional to the square of the thickness, it is possible to make the front sheet portion 3a and the back sheet portion 3b thinner by the amount of the strengthened bending strength. By increasing the thickness of the front sheet portion 3a and the back sheet portion 3b to about 0.6 to 2.0 mm, the front sheet portion 3a and the back sheet portion 3 are made heavier, and the pocket portions (3a, 3b). It is possible to strengthen the weight (weight stone) that suppresses the wind from rolling up.

In the orientation of the arrangement shown in FIG. 1, the film-like binding is continuous in the direction extending from the right end of the back sheet portion 3b, that is, in the direction orthogonal to the direction from the second upper portion to the second lower portion. The substitute portion 5a is fixed. In the clear file 1a according to the first embodiment, the binding margin portion 5a is on the fourth main surface of the back sheet portion 3b located in the back side direction of the paper surface of FIG. 1, along the right end portion of the fourth main surface. The joint portion of the binding margin portion 5a with respect to the back sheet portion 3b, which is joined in a strip shape in the vertical direction, is referred to as a "joint portion 13a". In the binding margin portion 5a, 30 binding holes 7a _{1 to 7a 30} are arranged in a row in the vertical direction. In the clear file 1a according to the first embodiment shown in FIG. 1, the number of binding holes is 30, but if it can be bound to a binder, it may be 2 or 4, and the number may be 2. It doesn't matter. The same concept applies to the number of binding holes in the subsequent embodiments.

The binding margin portion 5a is preferably made of a material thinner than the front sheet portion 3a and the back sheet portion 3b. The binding margin portion 5a may be any resin-based material. However, in order to make it easier to roll the clear file 1a when a plurality of clear files 1a are bound to the binder, the binding margin 5a is preferably made of polypropylene (PP) and has a thickness of about 0.05 to 0.20 mm. Is preferable. Further, the binding margin portion 5a may be a film using a plant-based biodegradable material.

The joining material of the joining portion 13a is preferably transparent in view of the ease of viewing the filing object from the back sheet portion 3b side. Other joining methods such as adhesion using an adhesive or adhesive tape, thermocompression bonding, etc. may be used, and any joining method may be used as long as the joining portion 13a becomes transparent.

As shown in FIG. 3, in the clear file 1a according to the first embodiment, the opening 15a can be opened by bending the front sheet portion 3a and the back sheet portion 3b outward. The binding margin portion 5a fixed to the back sheet portion 3b also deforms together according to the bending of the back sheet portion 3b. Although not shown, the opening 15a can be opened in the same manner even when the clear file 1a according to the first embodiment is still bound to the binder. Since the binding margin 5a, which is the portion bound to the ring, is made of a thin and soft material, even if the back sheet portion 3b is in a bent state as shown in FIG. 3, the binding margin is as much as shown in FIG. This is because the portion 5a can be prevented from bending. One or two filing objects such as documents to be put in the clear file 1a according to the first embodiment are assumed, and the filing object can be sufficiently put in and out of the clear file 1a by opening the opening 15a a little. It is possible. If there is an opening on the opposite side of the opening 15a, the filing object can be taken in and out from the opening as well.

FIG. 4 illustrates a state in which the score 31 is placed in the clear file 1a and the opening 15a is closed again. Although it is shown in FIG. 4 that the score 31 can be confirmed through the front sheet portion 3a, the contents such as the score 31 can be confirmed from the back sheet portion 3b side as well. Even if the joint portion 13a of the binding margin 5a partially overlaps the contents, if the binding margin 5a is transparent and the material of the binding portion 13a is also transparent, the contents can be sufficiently visually recognized. It is possible.

As shown in FIG. 5, the first clear file 1a ₁ , the second clear file 1a ₂ and the third clear file 1a ₃ can be used by binding to the binder according to the first embodiment. .. The first clear file 1a ₁ , the second clear file 1a _2, and the third clear file 1a ₃ all have the same structure as the clear file 1a according to the first embodiment.

In FIG. 13B, the _{front sheet portion and the back sheet portion of the second} clear file 1a 2 are hard and therefore not deformed, but the binding margin portion has a more soft film shape and therefore has a binding margin. The portion can be deformed to cause bending. From the state of FIG. 13B, the second clear file 1a ₂ is further slid toward the center side of the binder and lifted, that is, the second clear file 1a ₂ is from the third clear file 1a _3. FIG. 13 (c) shows a state in which a force is applied by the hand 51 in the direction of separation. In FIG. 13 (c), of the second clear file 1a ₂ , the portion where the hand 51 is hung is in contact with the third clear file 1a ₃ , but the portion near the center side of the binder is It is in a state of being slightly floating from the _third clear file 1a3. From the state shown in FIG. 13C, when the hand 51 is _{pressed against the second} clear file 1a 2 and further slid toward the first clear file 1a _{1 , three second} clear files 1a 2 are obtained.
