Description

DETAILED DESCRIPTION OF THE INVENTION INDUSTRIAL APPLICATION Field of the Invention This application compares a binding part of a back cover having a binding piece integrally with a binding part of a cover having a binding hole by a sheath body. It relates to files that bind thin documents.

2. Description of the Related Art Conventionally, a back cover and a front cover are integrally connected to each other via a fold line, and a pair of cut-and-raised binding pieces are separated from each other near the fold line position of the back cover. A pair of binding holes through which the binding pieces are inserted are formed near the folding line position, and after binding the required document, the binding pieces are inserted into the binding holes of the front cover bound by the folding lines, and the binding pieces are inserted into the front cover. A file formed by folding a binding portion including the above-mentioned binding piece with a sheath body in this state is known from, for example, Japanese Utility Model Publication No. 56-151186.

However, according to the conventional file described above, since the front cover and the back cover are connected integrally, the front cover and the back cover are limited to a single material. For example, to make it easier to spread the bound documents, for example, when made of a flexible synthetic resin plate, the back cover becomes weak and inconvenient to use, and because the back cover has a strong back, When made of a relatively thick synthetic resin plate or cardboard, it is inconvenient to spread the documents and the cost is increased. In a binding operation of a document or the like, when a binding piece inserted into a binding hole of a document is further inserted into a binding hole of a front cover, the front cover and the back cover are continuous, and the binding piece and the binding Since the holes are close to each other, there is a defect that it is difficult to insert a binding piece into the binding holes.

Means for Solving the Problems Therefore, in order to achieve the above-described object, the present application extends a binding piece on each of upper and lower edges on a side edge of a binding portion provided on one side,
In addition, a folded piece protruding from the back surface of the binding portion via a folding line is protruded, and the binding piece is engaged with the binding portion along the upper and lower edges of the folded piece at the position of the binding portion. A back cover provided with a notch, a front cover provided with a plurality of binding holes for inserting the binding pieces into the binding portion provided on one side, and a back closing the front and back pieces and their outer edges And a sheath that presses the binding portion of the front cover and the binding portion of the back cover at the inner edges of the front and back pieces. For convenience, the back cover is made of a thick synthetic resin plate, the front cover is made of a thin flexible transparent synthetic resin plate, and as convenient when pushing open the front and back pieces of the sheath, A cutout is formed at one or both corners above or below the inner edge of either the front or back piece of the sheath. It is.

In operation, when the back cover, front cover, and sheath are disassembled, they are inserted into the notch, and the binding holes of the document are inserted through the binding pieces standing up and down on the back cover. A document is inserted between the back cover and the front cover by inserting it into the binding hole of the front cover. The binding portion and the binding portion of the front cover are to be engaged from the top and bottom between the front and back pieces, and in this case,
By folding the binding pieces on the front cover surface in advance, the binding pieces easily intervene between the front and back pieces. In this state, the overlapping portion of the back cover, the document, and the front cover is strongly pressed by the inner edge of the front piece and the back piece. And the inner edge of the back piece is engaged with the folded piece.

Embodiment Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. In FIG. 3, (1) is provided with a binding portion (3) having a required width on one side via a hinge portion (2). The binding section (3)
And a folded piece (5) in which a pair of upper and lower binding pieces (4), (4), which are long in the up-down direction, are provided integrally at the upper and lower ends via folding lines (7) a, respectively. A thick, for example, black back cover made of a synthetic resin, such as polypropylene, provided with cutouts (6) that cut into the positions of the binding portions (3) along the upper and lower edges of the turnup pieces (5), respectively. (5) is folded back to the back surface of the binding portion (3), and the binding pieces (4) and (4) are respectively folded from the cut portion (6) by the folding line (7) b to the front surface of the binding portion (3). Stand up. In (8), a binding portion (10) having a required width is continuously provided on one side via a hinge portion (9), and the binding piece (4) is placed at an intermediate position of the binding portion (10). A thin and flexible transparent cover made of a synthetic resin such as polypropylene, for example, in which a pair of binding holes (11) to be inserted are formed. (12) is a binding portion of the back cover (1) and the cover (8). (3), (10) is a long transparent synthetic resin sheath that is inserted and clamped by being inserted from above and below, with a front piece (13) curved in the width direction and a horizontal back piece (14). And a back portion (15) for binding these outer edges to each other. The front piece (13) has a claw piece (16) projecting in a folded shape along the inner edge thereof, and a back piece (14). Each has a receiving piece (17) parallel to the back part (15) at a required interval, and a ridge (18) bulging inward along an inner edge.
(19) is an arc strip provided on one or both of the inner corners of the upper and lower ends of the back piece (14), preferably one of the front piece (13) and the back piece (14) of the sheath body (12). The cutout, (20) is the document to be sewn, (21) is the inner surface of
This is a headpiece inserted along 7).

Therefore, when using, back cover (1) and front cover (8)
After disassembling the sheath and the sheath (12), the binding holes of the document (20) are inserted into the binding pieces (4) and (4) standing up and down on the back cover (1). The document (20) is inserted between the back cover (1) and the front cover (8) by passing through the binding hole (11), and the end sewn in this state is provided on the sheath (12). The binding portion (3) of the back cover (1) and the binding portion (10) of the front cover (8) are pushed and opened at the position of the cut-off portion (19) while pushing the front piece (13) and the back piece (14) open. ) Is inserted between the front piece (13) and the back piece (14) from above and below. In this case, the binding piece (4) is bent in advance on the surface of the cover (8). By doing so, the binding piece (4) easily intervenes between the front piece (13) and the back piece (14). In this state, as shown in FIG. 2, the overlapped portion of the back cover (1), the document (20) and the cover (8) is
The claw piece (16) and the ridge (18) are strongly pinched, and the stopper in the lateral direction is locked by the claw piece (16) engaging with the side edge of the binding piece (4). This is performed by the folded piece (5) engaging with the inner edge of the back piece (14). The inner surface of the front piece (13) and its back (15) and the receiving piece (18)
And the head piece (22) is inserted between them and is seen through the front piece (13).

Effect of the Invention As described above, the present application has a configuration in which the front cover and the back cover are separated, so that a material suitable for each function can be freely selected, and a product having excellent functions can be provided. The operation of inserting the binding piece into the binding of the front cover can be easily performed, and the inside edge of the front piece is locked to the side edge of the binding piece, and the inside edge of the back piece is locked to the side edge of the folded piece. Therefore, the escape of the sheath body to the side can be prevented more reliably. Further, according to the configuration described in claim 4, there are advantages such as convenience in pushing open the front and back pieces of the sheath. Have.
