JPS58553Y2 - Binding cover - Google Patents

Description

[Detailed description of the invention] This invention allows the spine, front cover, and back cover to be assembled and separated, and the back of the spine can be freely adjusted according to the thickness of the paper sheets to be bound. This relates to a binding cover that can be made into a paperback cover, and an example thereof will be explained in detail below based on the drawings. 3, and the spine 1 has a plurality of fold lines a extending in the vertical direction in its middle part.

B are arranged side by side symmetrically, and the distance between fold line a closest to the end and fold line 2 is the maximum on the back, and fold line a closest to the center
The distance between the front cover 1 and the fold line is set to be the minimum on the back, and the left and right sides of the back cover 1 have lengths extending in the vertical direction for inserting and connecting the front cover 2 and the back cover 3, respectively. Hole 4
, 4 are drilled.

The front cover 2 and the back cover 3 are boards of the same shape, with concave cutouts 5 having a required width facing each other at the top and bottom positions near one end, and a cover part 6 and a connecting part 7 integrally formed. Consists of a shaped body,
At the upper and lower positions of the connecting portion 1, a fold line C extending horizontally along the horizontal edge of the cutout portion 5 is placed at the edge of the housing connecting portion 7 in the vertical direction for forming the binding piece 8. A folding line d extending in the direction of
is drilled.

When the spine 1, front cover 2, and back cover 3 are combined to form a binding cover, the upper and lower parts of the connecting portion 7 of the front cover 2 and back cover 3 are aligned with the imaginary line in Figure 2. As shown, the broken line e
, e respectively, and in this state, insert the connecting portion 1 into the elongated hole 4 of the spine 1 from the outside to expose the connecting portion T on the inner surface of the spine 1, and The upper and lower parts are returned to their original positions to form a binding cover as shown in FIG.

In this state, the front cover 2 and the back cover 3 are freely movable in the left-right direction with respect to the spine 1, corresponding to the width t of the notch 5.

Next, when binding paper sheets 10 into this binding cover, fold the binding piece 8 of both covers 2 and 3 along the fold line d so that the binding pieces 8 of both covers 2 and 3 face each other. A sheet of paper 10 is interposed between the sheets 8 and 8, and the sheets are bound together with a binding string or a binding fitting 11 to perform binding as shown in Fig. 3-4.
The back of the spine 1 is adjusted in accordance with the stacking thickness of the sheets.

This invention is structured as described above, so the back cover and
The front cover and the back cover can be disassembled and assembled very easily, and during transportation and packaging, each cover can be disassembled and then polymerized to form a three-layer structure, which is not bulky and each It has the advantage that the cover is very easy to manufacture.

[Brief explanation of drawings]

The drawings show an embodiment of the present application. Fig. 1 is a perspective view of the folded cover in an open state, Fig. 2 is a perspective view of the front cover and spine in an exploded state, and Figs. 3 and 4 are views of the paper. FIG. 2 is a side view of a binding cover with leaves bound therein and a portion thereof in cross section. In the figure, 1 is the back cover, 2 is the front cover, 3 is the back cover, 4 is the long hole,
5 is a notch portion, 6 is a cover portion, 7 is a connecting portion, 8 is a binding piece, a
, b, c, and d are broken lines.

Claims (1)

[Scope of utility model registration request] The cover portion and the connecting portion are integrally formed by providing cutout portions having a required width at the upper and lower positions, and the connecting portion has a horizontal fold line for bending the upper and lower portions, and a binding portion is provided at the end edge. A front cover of the same shape each having a vertical fold line for forming a folding piece, a back cover, a plurality of fold lines extending in the vertical direction in parallel in the middle part, and a vertical fold line in the left and right sides. 1. A binding cover, which is formed by cutting out from a spine cover provided with elongated holes extending from each side, and inserting the connecting portion into the elongated hole with its upper and lower portions bent.
