Description

  The present invention relates to a holder suitably used for filing paper sheets and the like.

As this type of holder, for example, a rail holder shown in FIGS. 6 and 7 is known.
The rail holder 100 includes a back binding rail 101 that also serves as a back cover, and a pair of clamping pieces 102 that are formed integrally with the back binding rail 101. Further, each sandwiching piece 102 is formed integrally with the back binding rail 101, and its tip portion is closed so as to be opened and closed by the elastic restoring force of the holder 100.

  Further, the usage method will be described. The paper sheet 104 is sandwiched between the transparent cover body 103, and then the back binding rail 101 is abutted against the corner portion 105 of the cover body. Further, in this state, the corner portion 105 of the cover body is sandwiched between the sandwiching pieces 102, and the back binding rail 101 is slid along the edge of the cover body 103 while maintaining this state. Therefore, the paper sheet 104 and the cover body 103 are sandwiched by the holder 100 together.

  Further, in this type of holder, each sandwiching piece 102 has a shape that bulges outward, so that it does not come into contact with the cover body 103 on the inside, and the pressing edges 108 and 108 at the left and right ends of the opening of the sandwiching piece 102 are formed on the cover body 103. Abut. Therefore, when an external force is applied to the cover body 103, the cover body 103 and the paper sheet 104 are strongly sandwiched only by the tip portion of the sandwiching piece 102, and the holder 100 is prevented from falling off.

  By the way, this type of holder is stacked on a desk in use or stored in a bookshelf or the like in an aligned state. For this reason, if the width of the holder is wide, the holders interfere with each other and become bulky. Therefore, when considering usability, a holder having a narrow width is desired.

  In particular, the rail holder 100 described above has various measures against dropping, but the sandwiching piece 102 is curved and bulges outward, and the cover body 103 is folded inside the holder 100. The width of the holder had to be wide.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a holder that can be used without being bulky even when the holder is used while preventing the holder from falling off.

In order to achieve the above object, the present invention is configured as follows.
That is, the rail body extends along one side edge of the sheet to be bound, and forms the spine portion of the sheet when the sheet is bound, and extends in the same direction from both edges of the rail body. And a pair of sandwiching plates biased in a direction approaching each other, and when the sheet is bound, a holder for sandwiching and holding the sheet between the sandwiching plates,
In the normal state, the sandwiching plate has an acute angle with the rail body, and an inner surface from the tip to the rail body is a flat surface.

  Here, “one side edge of the sheet” is a binding margin side to be bound to the book holder in the sheet to be bound. Further, here, “normal state” is a state in which no external force is acting on the sandwiching plate.

  The present invention configured as described above has a flat inner surface from the front end of the holding plate to the rail body. Therefore, the clamping plate and the sheet are in surface contact with each other over a wide range, and a sufficient holding force is obtained by the friction. Further, since the sandwiching plate is always in close contact with the sandwiched sheet, the sandwiching plate does not bulge outward, and as a result, a narrow holder is obtained. In this case, if the outer surface from the front end of the clamping plate to the rail body is also formed as a flat surface, the holder can be surely narrow.

  It is desirable that the pair of sandwiching plates have the same length in the extending direction. That is, since the clamping plates are arranged according to the isosceles triangle arrangement with the rail body as the base, each clamping plate contacts the front and back of the seat with the same force. For this reason, the holding force becomes even on the front and back of the sheet, and the stability increases.

  The length of the clamping plate may be set in a range of 2 to 4 times the back width of the rail body. More preferably, when it is set to about 2.75 times, the workability when sandwiching the sheet and the holding force of the sheet by the sandwiching plate are improved.

  Further, the material of the sandwiching plate and the rail body is PS (polystyrene), and more preferably, the sandwiching plate and the rail body are integrated. In this case, due to the characteristics of PS (polystyrene) with appropriate elasticity, the holder can be easily inserted into and removed from the sheet. Further, if the holding plate and the rail body are integrated, the holder can be easily manufactured by integral molding or the like.

  As described above, according to the present invention, it is possible to provide a holder that can be used without being bulky even when the holder is used while suppressing the drop-off of the holder.

It is a figure which shows the use condition of the holder shown to this Embodiment. It is a side view of the holder simple substance shown in this Embodiment. FIG. 3 is a cross-sectional view taken along line AA ′ in FIG. 2. It is a figure explaining the usage method of the holder shown to this Embodiment. It is principal part sectional drawing which shows the state by which the sheet | seat was pinched | interposed into the holder shown in this Embodiment. It is a perspective view which shows the conventional rail holder. It is BB 'sectional drawing of FIG.

Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.
First, the outline of the holder 1 will be described with reference to FIG. 1. The holder 1 extends along one side edge of the sheet 10 to be bound by the holder 1, and the spine portion at the time of binding of the sheet 10 And a pair of clamping plates 30 that extend in the same direction from both edge portions 22 of the rail body 20 and are urged in a direction approaching each other.

  Examples of the sheet 10 bound to the holder 1 include paper sheets 11 and a clear sheet 12 used as a cover cover and a back cover. Then, holders 1 having different lengths and accommodation numbers are prepared according to the size of the sheet and the number of sheets to be bound, and for example, about 5 to 40 sheets can be bound.

  The details of the holder 1 will be described. The rail main body 20 is formed slightly longer than the binding margin side edge of the paper sheet 11 to be bound, and is used as a back cover of the sheet 10 when used. And a pair of clamping plates 30 and 30 are integrally formed in the both sides in the longitudinal direction of this rail main body 20. As shown in FIG.

  The rail body 20 and the sandwiching plate 30 are formed of a flexible material as an integral product, and the sandwiching plate 30 is urged toward each other by the elastic restoring force of the material. More specifically, as shown in FIG. 3, a clamping plate 30 is formed via a bent portion 35 in which an angle θ formed between the rail body 20 and the clamping plate 30 is an acute angle, and an external force acts on the clamping plate 30. In a state where it is not, the front ends 31 of the sandwiching plates 30 are in contact with each other and are openably closed.

Further, the inner surface 36 of the sandwiching plate 30 is formed as a flat surface. Specifically, as shown in FIG. 3, in the cross section of the clamping plate 30, the inner side surface of each clamping plate 30 from the tip 31 to the rail body 20 is formed in a straight line.
Further, the sandwiching plate 30 is formed in a flat surface with the outer surface from the tip 31 to the rail body 20 being in a straight line.

On the other hand, the length L2 of the clamping plate 30, that is, the length L2 in the extending direction of the clamping plate 30 is in the range of 2 to 4 times the width L1 (back width) of the rail body 20, as shown in FIG. The length is set. Preferably, when PS (polystyrene) is selected as the material of the main holder 1 and the thickness of the main holder 1 is set to about 0.8 mm, an optimum holding force is obtained with a length of 2.75 times.
In addition, when PS (polystyrene) is selected as the material of the rail body 20 and the sandwiching plate 30, an appropriate elastic restoring force and resistance can be obtained, and the insertion and removal of the holder 1 with respect to the sheet 10 can be smoothly performed. can get.

Then, the usage method of this holder 1 is demonstrated using FIG.
First, several sheets 11 of sheets to be bound are sandwiched between clear sheets 12 serving as a front cover and a back cover. Subsequently, the main holder 1 is applied to the corner 13 on the binding margin side of the clear sheet 12, and the corner 13 of the clear sheet is inserted between the sandwiching plate 30 and the sandwiching plate 30. When the main holder 1 is slid along the edge of the clear sheet 12 while maintaining this state (arrow A in FIG. 4), the paper sheet 11 is sandwiched and held by the main holder 1 together with the clear sheet 12.

When an appropriate number of sheets are bound in the holder 1, the inner surface 36 of the clamping plate 30 and the clear sheet 12 are in surface contact with each other over a wide range as shown in FIG. For this reason, moderate friction arises between the inner surface 36 of the clamping plate and the clear sheet 12, and a holding force is obtained. Therefore, the drop-off of the holder 1 is suppressed.
Even when the sheet 10 is sandwiched, the holding plates 30 are attached to the surface of the clear sheet 12, so that the holder 1 does not bulge outward and is slim. Therefore, even if a plurality of sheets bound by the holder 1 are overlapped, it is not bulky and is easy to use.

  The above-described embodiment is merely an example of the present invention, and for example, an oblique cutout 40 may be provided in the corner portion 32 of the sandwiching plate 30. In this case, when the sheet 10 is inserted between the sandwiching plates 30, the pressure is dispersed by the notches 40, so that the sheet 10 can be easily inserted.

  Further, PS (polystyrene) is selected as the material of the holder 1, but it is not always necessary, and it can be integrally formed, and if it is a material having elasticity and restoring force that can be bent by a force applied with a finger or the like, Can be arbitrarily selected. For example, PVC (vinyl chloride), POM (polyacetal), PP (polypropylene), or the like can be used.
