Description

[Detailed description of the invention] Industrial applications The main petition is. Concerning binding tools for binding documents, etc.

BACKGROUND ART Conventionally, a pair of left and right holes are bored in the center of an elongated presser having guide grooves on both sides along the longitudinal direction, and a binding piece is inserted into these holes, and the left and right positions of the presser are adjusted. There is a known binding device in which the binding pieces are bent outward by a slider slidably disposed on the binding piece, and the bent portions are restrained to bind documents inserted through the binding pieces. .

Problems to be Solved by the Invention However, according to the above-mentioned conventional binding tool, when binding documents, two sliders are slid respectively.
It is necessary to perform an operation to release the restrained state of the folded part of the binding piece, and an operation to restrain the folded part again, respectively, which makes the binding operation troublesome, and it is difficult to do so with the presser inserted through the binding piece. There was an inconvenience in that it was not possible to view documents while flipping through them.

Means for Solving the Problems Therefore, in order to solve the above-mentioned problems, the present application provides a plurality of flexible binding pieces on a long board so as to be bendable in a direction orthogonal to the longitudinal direction of the board. Front and rear edges are formed symmetrically at the center position in the width direction of the binding piece and the elongated plate, corresponding to the binding pieces, respectively, and the front and rear edges form a wide part and an inclined part. An insertion hole for a binding piece having a series of narrow parts in the longitudinal direction is opened at the bottom, and the binding piece is allowed to be inserted in the front and rear positions of the upper part opposite to the insertion hole, and the narrow part and and a holding part piece each having a binding part symmetrically having a restraining part for bending and restraining the binding piece, and a plurality of flexible parts that can be attached to a member such as a file. Front and rear edges are formed symmetrically at the center positions in the width direction of the binding piece and the long plate piece, corresponding to the binding piece, respectively, and the front and rear edges define the wide part, the inclined part, and the narrow part in the longitudinal direction. A series of insertion holes in the direction of the binding strips are provided at the bottom, and the binding strips are allowed to be inserted in the front and rear positions of the upper part opposite to the insertion holes, and the binding strips are inserted between the narrow part and the It is characterized in that it is composed of a presser piece, each of which has a binding part symmetrically provided with a restraining part that bends and restrains the binding piece, and in the above, preferably the binding piece, The binding piece and the holding piece are each made of synthetic resin, and in order to prevent the binding from loosening, a non-slip part is formed on one side of the folded side of the binding piece, and the position of the narrow part in the insertion hole is A tongue piece for a stopper is provided protrudingly at the position of the restraining part facing the narrow part, and the binding piece is formed flat on the bending side in order to allow the raising and lowering operation of the binding piece. It is.

Function: Although the binding piece may be used as it is, its substrate is fixed to a member such as a file, or the binding piece is directly inserted and attached to a member such as a file.

In this state, each binding piece is inserted through the binding hole drilled in the document, and then inserted through the wide part of the insertion hole and the restraining part located on the front side, and the document is placed so that the plate piece faces the board. Then press the plate piece in the direction of the narrow part of the insertion hole. Then, the board pieces slide on the top surface of the document, and each binding piece reaches the narrow part through the inclined part, and at this position, each binding piece is simultaneously bent toward the front in the gap by the restraining part and laid down. However, in this state, the binding piece is restrained, and in this restrained state, the edge of the narrow width part engages with the non-slip part.

In this stapling state, for example, when a file or a base plate is placed on a document with the wide part of the insertion hole facing upward, an external force is applied to the holding piece in the direction of the narrow part due to the impulse or vibrations during handling. When this action is applied, there is a risk that the presser piece will slide and the binding piece will move to the wide part, causing the binding state to become loose inadvertently. and prevent that fear.

In addition, when flipping over a stacked document to view its written contents with the presser piece inserted through the binding piece, the middle of the binding piece is temporarily attached to the binding part.

Embodiments Examples of the present application will be described in detail below based on the drawings.

The present invention is composed of a binding piece A and a presser piece B, and both the binding piece A and the presser piece B are made of synthetic resin. The binding piece A has holes 2, 2 for attaching a file cover etc. at both ends of a long board 1, and holes 2, 2 for attaching a file cover etc.
A pair of binding pieces 3, 3 which are flat in the longitudinal direction of the substrate 1 are integrally provided slightly inward from the substrate 1 so as to be bendable in a direction orthogonal to the longitudinal direction of the substrate 1. The surface has a non-slip part 4 made of fine irregularities.
However, each tip is integrally provided with a tapered locking portion 5 that bulges in the direction of one side.

The presser piece B is also formed to be longer, and is a plate integrally formed with a ridge portion 6 having an arc-shaped cross section along the longitudinal direction and having both ends closed in an arc shape. As is clear from FIG. 4, the front and rear edges are bent symmetrically in the longitudinal direction, and there is a wide part 8a and a wide part 8a between the front and rear edges, which are bent symmetrically in the longitudinal direction, as shown in FIG. , an insertion hole 8 for inserting the binding piece 3 having a series of inclined parts 8b and a narrow width 8c approximately equal to the thickness of the binding piece 3 is opened, and the narrow width part 8c is closer to the inclined part 8b. A bottom portion 10 having a tongue piece 9 for a stopper protruding inwardly at the front edge position of the bottom portion 10.
Then, by separating the gap 11 necessary for bending the binding piece 3 from the bottom part 10, the front and rear edges of the ridge part 6 in the width direction are made to protrude beyond the edges at the position of the narrow part 8c. , and by making cuts in the length range of the insertion hole 8 so as to be recessed from the edge at the position of the wide part 8a, the binding piece 3 can be inserted at the position of the wide part 8a, and the narrow width can be reduced. Binding parts 13, 13 symmetrically having a pair of front and rear restraining parts 12a, 12b which bend and restrain the binding piece 3 at the position of the part 8c are provided. 14 is a recess for saving material.

Therefore, when using the binding piece A, it is possible to use it as it is, but it is preferable to use the folding part c of a film cover in which a front cover a, a spine cover b, a folding part c, and a back cover d are provided in series. Alternatively, the substrate 1 is fixed to a required member such as the side edge of the base plate through the holes 2, 2.

In this state, the binding hole punched in the document P is attached to the binding piece 3.
3, the document P is inserted through the wide width 8c of the insertion hole 8 and, for example, the restraining part 12a located on the front side, so that the plate piece 7 faces the substrate 1.
Then press the plate piece 7 in the direction of the narrow part 8c. Then, the plate piece 7 slides on the surface of the document P, and the binding pieces 3, 3 reach the narrow part 8c via the inclined part 8b, and at this position, each binding piece 3, 3 moves toward the front side. The plate pieces 7 are simultaneously bent toward the front within the gap 11 by the positioned suppressing portions 12a, and are suppressed while lying down toward the front edge side of the plate piece 7. At this time, the non-slip part 4
The edge of the narrow portion 8c engages with the edge of the narrow portion 8c.

In this loaded state, for example, when a file or a base plate is placed on a bookshelf or the like with the wide part 8a of the insertion hole 8 facing upward, the presser piece B may become thin due to the impulse or vibration during handling. When an external force in the direction of the width part 8c, that is, a downward external force in FIG. 6 is applied, the presser piece B slides downward, the binding pieces 3, 3 move to the wide part 8a, and the restraining state is released. Although there is a risk that the binding may loosen, in this example, as shown in FIG. 8, the tongue piece 9 comes into contact with the side edge of the binding piece 3 to prevent the presser piece B from sliding downward.

In addition, when flipping over the bound documents to view the written contents with the binding pieces 3, 3 inserted with the presser piece B, as shown in Fig. 7, the binding pieces 3, 3 The narrow part 8c of the insertion hole 8 prevents the middle part.

In the above-mentioned embodiment, the binding piece is integrally provided on the board, but the board may be omitted and the binding piece itself may be inserted into the folded part, for example, as in the case of a known flat file. Of course, it may also be attached by other means.

Further, in the above embodiment, the stopper tongue piece 9 is provided inwardly protruding from the front edge of the narrow portion 8c of the insertion hole 8 near the inclined portion 8b. Even when the direction of the tongue 8 is reversed, the stopper function can be achieved and the tongue piece 9 can be shared. Further, in the above, the tongue pieces 9 may be provided to protrude upward, and in this case, they are provided symmetrically on the front and rear edges of the narrow portion 8c.

FIG. 9 shows the inclined portion 8b of the narrow portion 8c of the insertion hole 8.
In the case where the tongue piece 9' is provided inwardly protruding from the rear edge of the side,
Further, FIG. 10 shows the restraining part 1 facing the narrow part 8c.
A case is shown in which tongue pieces 9'' are respectively provided downwardly protruding from the front and rear edges of 2.

Effects of the Invention As described above, according to the present application, it is possible to bend and restrain a plurality of binding pieces at the same time by sliding the presser piece in its longitudinal direction. Since the parts are formed symmetrically in the width direction of the plate piece, regardless of the directionality of the holding piece, as long as the binding piece is always inserted through the restraining part at the front position,
The binding strips can be folded toward the front and held in place, making it extremely easy to bind documents, etc., and convenient to handle. It is also effective when binding documents in several places, and it is convenient because it allows you to read the contents of the document while binding it without removing the presser piece from the binding piece. Further, according to the present invention, since the slider of the conventional structure can be omitted, sufficient mechanical strength can be obtained by forming the presser piece itself thickly, and it also has advantages such as being able to be molded with synthetic resin. Furthermore, in the present application, a non-slip part is formed on one side of the folded side of the binding piece, and a tongue piece for a stopper is provided protrudingly at the position of the narrow part or the position of the restraining part in the push-through hole. When the binding piece is formed into a flat shape on the folded side, the binding piece has the advantage of being easy to raise and lower.
