Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a clip file configured to hold paper sheets interposed between a back cover and a binding section by the clamping force of the clips.

Conventional technology Conventionally, on one side edge of the back cover made of a thick rectangular synthetic resin board, there was a narrow back cover, a wide front part extending horizontally inward from the back cover, and a section from the front part to the bottom of the back cover. A wide folded part that is folded back to the side, and then a V
Locking pieces slightly wider than the back cover bent in a letter-like shape are sequentially arranged via valley fold lines, and these are folded so that the back cover, the front part, and the folded part overlap in the vertical direction. a file main body, which forms a binding section, and is provided with an operation hole opening from the spine section to the front section at the center of the filing section;
a cover plate made of a thin rectangular synthetic resin plate having a size that covers the surface of the back cover whose side edges are welded to the outer surface of the folded part, and an elastic metal plate having a U-shaped longitudinal section; A clip is provided at the tip of the upper piece and has an engaging part that bends inward and engages with the locking piece, and the lower piece holds this clip at the position of the operation hole when the lower piece is attached to the back cover. The upper piece is slidably attached to the binding section so as to be in sliding contact with the lower surface and interposed between the front section and the folding section through the operation hole, and the paper sheet is inserted between the folding section and the back cover. Clip files are already known which are configured to pinch the paper.

Problems to be Solved by the Invention Incidentally, in the conventional clip file described above, the locking piece that the engaging portion of the clip engages is made of a file body made of a relatively expensive thick synthetic resin plate. Since it is integrally installed on one side edge over the entire length of its front and rear width, it has the following disadvantages.

In other words, the locking piece made of a thick synthetic resin board always has a strong restoring force in the upright direction, so it can be pressed in the upright direction when paper sheets are loaded and by pulling the clip outward. However, when the sheets are released, the upper part of the clip, which is harder near the center of the locking piece, prevents it from tilting in the upright direction; Since the above deterrent effect does not work at the end position of the direction,
The ends of the locking pieces tend to press strongly against the inner surface of the front surface of the binding section, which not only causes the binding section to swell over time and spoil its appearance, but also to store a large number of clip files in a file box, etc. There was an inconvenience that the number of books stored in the clip decreased accordingly when the paper was stored in the paper.

Means for Solving the Problems Therefore, in order to solve the above-mentioned problems, the present application provides a locking piece on a cover plate made of thin synthetic resin instead of a locking piece made of a thick synthetic resin plate. , a back cover made of a thick rectangular synthetic resin board, with a narrow spine on one side edge, a wide front that bends horizontally inward, and a fold back from the front to the bottom. The wide folding portions are successively arranged via the valley fold lines, and these are folded so that the back cover, the front portion, and the folding portion overlap in the vertical direction to form a binding portion. a film body having an operation hole opening from the cover section to the front surface at the center of the section; A cover plate made of a thin rectangular synthetic resin plate having a size that covers the surface of the back cover and having a locking piece slightly wider than the back cover bent in a V-shape, and a cover plate having a vertical cross section of the same size. The clip is made of a letter-shaped elastic metal plate and has an engaging part at the tip of the upper piece that bends inward and engages with the locking piece, and the clip is inserted into the operating hole. At the position, the lower piece is slidably attached to the folding part so that the lower piece is in sliding contact with the lower surface of the back cover, and the upper piece is interposed between the front part and the folding part through the operation hole, The paper sheet is configured to be compressed between the folding part and the back cover.

When in use, the upper and lower pieces of the clip are grasped with fingers at the position of the operation hole, and the engaging part of the clip that slides outward engages with the locking piece of the cover plate. As a result, further sliding is prevented. In this state, the end of the paper sheet or the like is interposed between the back cover and the cover plate at the position of the binding section. Then, when the clip is pressed again toward the file body, the upper piece of the clip penetrates deeply into the binding part, and the engaging part and lower part sandwich the cover plate and the sheet between the back cover and the folding part. wear.

Embodiments Hereinafter, embodiments of the present application will be described in detail with reference to the drawings. 1
As shown in FIG. 2, on one side edge of a back cover 2 made of a thick, rectangular synthetic resin board with a desired color band, a narrow spine 3, a wide front part 4, A folding margin 5 having a narrower width than the back cover 3 and a folding part 6 having a width approximately equal to the front part 4 are connected via valley fold lines 7, 8, 9, and 10, respectively, to form the back cover 2.
A file body 12 is formed at the center of the spine 3 by bending along the valley fold lines 7, 8, 9, and 10 so that the folding portion 6 overlaps with the surface thereof to form a flat square binding portion 11. This operating hole 12 is continuous with an arc-shaped notch 13 formed at the center of the front portion 4. Reference numeral 14 indicates a cover plate made of a thin, preferably transparent synthetic resin plate having a size that covers the back cover 2, and integrally has a side edge portion 15 approximately equal to the folded portion 6 on one side edge thereof. , whose side edge 15 is welded to the lower surface of the folded part 6, and whose width is slightly wider than the width of the spine 3, preferably through the valley fold line 16 of the outer edge of the side edge 15. A trapezoidal locking piece 17 that is longer than the length of the operation hole 12 and shorter than the entire length of the side edge portion 15 extends in the center opposite to the operation hole 12, and this locking piece 17 has a V-shape. It is folded back between the front part 4 and the folded part 6 in a state of being bent inwardly and tilted inward. Reference numeral 18 denotes a clip made of an elastic metal plate having a U-shaped longitudinal section and having a length almost equal to the length of the operation hole 14, and has an upper piece that is inclined forwardly downward and intervenes in the binding section 11 from the operation hole 12. 18a has an engaging portion 18b bent inwardly into a U-shape and engages with the locking piece 17 at the leading edge of the bottom piece 18a, and the lower piece 18c slides into contact with the lower surface of the back cover 2. In addition, the engaging portion 18b and the lower piece 18c
The back cover 2 and the side edge portion 15 are pressed between them.
p is a paper leaf.

However, when using it, as before,
First, the clip 18 facing the notch 13 of the operation hole 12
Using your fingers, hold the upper piece 18a of the clip 18 and the lower piece 18c of the clip 18 that slides into contact with the lower surface of the back cover 2.
When the clip 18 is pulled outward, the engaging portion b of the clip 18 engages with the cover plate 1, as shown by the imaginary line in FIG.
4, and is prevented from being pulled out outward at that position.

In the above, when the clip is strongly pulled outward, the length of the locking piece 17 is longer than the length of the operation hole 12, and the width of the locking piece 17 is wider than the width of the spine 3, so the clip is pulled outward. The engaging portion 18b of 18 does not go beyond the locking piece 17 and come out of the operation hole 12.

When the clip 18 is pulled out, the space between the folding part 6 and the back cover 2 can be opened, so that one end of the paper sheet p is interposed therebetween.
Next, when the clip 18 is pressed inward, the engaging part 18b comes off from the locking piece 17, and the clip 18 penetrates deeply into the binding part 11, and the engaging part 1
8b and the lower piece 18c, the paper sheet p is sandwiched between the back cover 2 and the side edge 15 of the cover plate 14,
The paper leaf p is bound.

Effects of the Invention As described above, according to the present application, the locking piece with which the engaging portion of the clip engages is not provided on the file body made of thick synthetic resin, but is attached to one side edge of the cover plate made of thin synthetic resin. Therefore, even if the locking piece rises and comes into contact with the inner surface of the front part, the front edge of the locking piece is prevented from pushing up the front part because the front part is harder than the locking piece. Therefore, there is no risk of the binding section bulging, and the original shape of the binding section can be maintained over a long period of time, giving it a good appearance.Since it does not have a locking piece made of thick synthetic resin, it is lightweight. Moreover, since the front cover can be obtained at a lower cost than the file main body, it has the advantage of being able to reduce costs.
