Ring-bound notebooks

Abstract

To obtain a ring opening body that can be used as a cover for a notebook and such and, if necessary, can be removed from the notebook and such and used as a ring opening body to open the double ring.SOLUTION: A punched piece 7, which is removable by a discontinuous cut line, is formed on a cover 5 of a notebook 1 bound with a double ring 3 forming a circular section 4. The punched piece 7 removed from the cover 5 is folded and made into an operation piece to be inserted into the circular section of the double ring of the notebook for expanding. This operation piece has an inward bending part made by folding one end of the punched piece removed from the cover and further folding it back, and an outward bending part made by further folding back one end of the inward bending part. The leading end of the outward bending part is inserted into the circular section from one end of the double ring and moved toward the other end side, allowing the thickness increased by the inward bending part to push and expand the circular section.SELECTED DRAWING: Figure 2

Description

Technical Field

[0001] The present invention relates to a ring opener for notebooks, which is used when opening the rings of notebooks bound by double rings to remove sheets from the notebooks or remove the rings.

Background Art

[0002] As means for binding notebooks with rings, spiral rings formed by forming a single wire into a spiral shape and sequentially inserting the same into binding holes of notebooks, and binding by non-spiral double rings are well known. This generally called double ring is formed by bending a wire rod into a zigzag shape with a constant width, bending the wire rod in the lateral width direction from the bent portions on both side edges to form an annular portion, and passing the annular portion through binding holes of notebooks to bind the whole together. (Patent Document 1)

[0003] In the above double ring, the annular portion can be brought into an opened state by expanding the gap between the bent portions on both side edges that form the opposed annular portions (rings). However, such a ring opening operation is not easy, and since wire rods are used, there is also a risk of injury. For these reasons, tools for opening the rings of double rings have also been provided (Patent Document 2)

Summary of the Invention

Problem to be Solved by the Invention

[0005] The tool used to open the rings mentioned above is effective, but it is separate from the notebooks. Therefore, the aim is to create a device that is integrated with notebooks bound with double rings, functions as a notebook at all times, and can be detached from the notebooks as needed to open the rings at any time. [Means for solving the problem]

[0006] The present invention relates to notebooks bound with double rings forming an annular portion, wherein a die-cut piece is formed on the cover of the notebooks by discontinuous cut lines, and the die-cut piece removed from the cover is folded and inserted into the annular portion of the double rings of the notebooks to form a ring-opening mechanism for the notebooks.

[0007] Furthermore, the aforementioned operating piece is provided with an inwardly folded portion, which is formed by folding one end of the die-cut piece removed from the cover, and then folding this portion back, and an outwardly folded portion, which is formed by folding one end of the inwardly folded portion back. The tip of the outwardly folded portion can be inserted into the annular portion from one end of the double ring and moved toward the other end, thereby expanding the annular portion due to the increased thickness created by the inwardly folded portion and the outwardly folded portion. [Effects of the Invention]

[0009] As described above, in this invention, a die-cut piece is formed on the cover of notebooks bound with double rings, which can be removed by discontinuous cut lines. Whenever you want to remove the notebook paper or the rings, you can remove the die-cut piece from the cover and fold it to form an operating piece. Inserting one end of this operating piece into the annular portion of the double ring and moving it to the other end of the ring will push the annular portion open, allowing you to easily open the ring. [Brief explanation of the drawing]

[0010] [Figure 1]This is a plan view illustrating an embodiment of the present invention, showing a notebook cover with a die-cut piece attached. [Figure 2] Figure 1 is an explanatory diagram showing the state after the die-cut piece has been removed from the cover. [Figure 3] This is an explanatory diagram showing the folded state of the punched piece removed in Figure 2, rotated 90 degrees. [Figure 4] Figure 3 shows a perspective view of the completed folding state of the operating piece. [Figure 5] Figure 4 is an explanatory diagram showing the state in which the ring at one end of the double ring is inserted. [Figure 6] Following Figure 5, this is an explanatory diagram showing the state in which the operating piece is moved toward the other end of the double ring. [Figure 7] This is a plan view showing another embodiment of the present invention with the punched-out piece removed. [Figure 8] This is a plan view showing another embodiment with the punched-out piece removed. [Figure 9] This is a plan view showing another example with the punched-out piece removed. [Modes for carrying out the invention]

[0011] Notebooks consist of numerous sheets of paper sandwiched between the front and back covers, with numerous binding holes 2 provided along one side edge. Double rings 3 are passed through these binding holes 2 to form a ring portion 4, resulting in notebooks 1 bound with double rings.

[0012] The cover of notebooks is made of cardboard that is thicker than the paper sandwiched inside, and should be of an appropriate thickness, but preferably slightly thicker than a typical cover, with a basis weight of approximately 250-400 g / m². 2 In most cases, it's best to use material with a thickness of around 0.35 to 0.45 mm. In some cases, a plastic cover may be acceptable. A punched piece 7 is formed by discontinuous cut lines 6 on the cover 5 of such notebooks. Usually, it is preferably provided on the back cover, but it may be provided on the front cover, or may be provided on both depending on circumstances. The above-mentioned notebooks is a broad concept including various items that are bound using double rings, such as notebooks, sketchbooks, drawing pads, planners, and calendars.

[0013] In the illustrated example, a four-leaf-shaped punched piece 7 is formed on the cover 5 by discontinuous cut lines 6. This punched piece 7 is provided with a cut line 8 on the right side that divides the punched piece into upper and lower parts, and a first fold line 11 on the left side, and is provided with a second fold line 12 and a third fold line 13 that intersect the first fold line 11 and divide the punched piece 7 into left and right parts.

[0014] Then, so as to be parallel to the second fold line 12 and the third fold line 13, a fourth fold line 14 and a fifth fold line 15 are formed on the side where the cut line 8 is located. Further, a sixth fold line 16 extending obliquely from the right end 9 of the cut line 8 toward the fourth fold line 14 is formed, and similarly, a seventh fold line 17 extending obliquely toward the fifth fold line 15 is formed. In the above description, terms such as upper, lower, left, and right are used, which is for the purpose of explaining the relative positional relationship in an easy-to-understand manner, and does not mean an absolute positional relationship. The same applies to the following description.

[0015] An appropriate number of connecting portions 18 can be provided at the intermediate portion of the cut line 8, and a plurality of cuts 19 can be provided at the intermediate portion of each fold line in the second fold line 12, the third fold line 13, the sixth fold line 16, and the seventh fold line 17. By providing the above-mentioned connecting portions 18, when the product is used as a notebook, even if the cut line is cut over a long length, the cut line will not be caught on other objects, and when the punched piece is used, the entire piece can be easily cut along the cut line by separating the connecting portions 18. Further, the notches 19 provided in each of the above folding lines can facilitate the folding work of each folding line even when a thick cover is used when used as a punched piece.

[0016] When using the punched piece 7 provided on this cover, first, the discontinuous cutting lines 6 are cut off to remove the punched piece 7 from the cover 5. (Figure 2) In order to make the following description easier to understand, the removed punched piece 7 will be described in a state where the connecting portion 18 of the cutting line 8 is cut off and the whole is rotated 90 degrees as shown in Figure 3. The first folding line 11 of the punched piece 7 is mountain-folded. When the second folding line 12 is valley-folded and the fourth folding line 14 is mountain-folded, an inner folded portion 21 is formed; and when the sixth folding line 16 is valley-folded, an outer folded portion 22 is formed. Similarly, when the third folding line 13 is valley-folded and the fifth folding line 15 is mountain-folded, an inner folded portion 21 is formed, and when the seventh folding line 17 is valley-folded, an outer folded portion 22 is formed. By forming such a folded state, the operation piece 23 is formed.

[0017] In the above description, after mountain-folding the first folding line 11 of the punched piece 7, the second folding line 12, the fourth folding line 14, and the sixth folding line 16 are sequentially folded, and similarly the third folding line 13, the fifth folding line 15, and the seventh folding line 17 are folded. However, it is also possible to first fold the second folding line 12, the fourth folding line 14, and the sixth folding line 16, similarly fold the third folding line 13, the fifth folding line 15, and the seventh folding line 17, and then fold the first folding line 11 to form the operation piece 23. The folding order can be changed as appropriate.

[0018] For the operation piece 23 of such a ring opener 25, when the tip end 24 of the outer folded portion 22 is inserted into the annular portion 4 from one end side of the double ring 3 and further moved toward the other end side of the ring, the overlapping portion of the outer folded portion 22 and the inner folded portion 21 has multiple layers of the folded cover material, so the annular portion 4 of the double ring 3 is sequentially expanded, whereby the annular portion can be brought into an open state. (Figures 5, 6) This allows you to remove the necessary notebook pages from the bound notebooks or even remove the double ring itself from the open ring section. If the double ring is removed, the double ring and the paper can be disposed of separately.

[0019] Figures 7 to 9 show other embodiments, in which the punched piece shown in Figure 7 is formed such that the length of the first fold line 11 on the left side is shorter than the cut line 8 on the right side. The punched piece shown in Figure 8 is formed in a nearly circular shape instead of the four-leaf shape described above. The object shown in Figure 9 has a nearly angular shape. These can also be used in the same manner as those described above, and the shape of the punched pieces is not particularly limited. Furthermore, for books with rigid covers that cannot be folded, it is possible to create die-cut pieces by binding them to the inside of the cover in a way that resembles an inner cover.
