Abstract
Description
Technical Field
[0001] The present invention relates to a binding band and a ledger with a binding band.
Background Art
[0002] Notebooks, planners, diaries, memo pads, and other ledger papers (hereinafter collectively referred to as "ledger papers") are manufactured by arranging a plurality of sheets of the same type between a front cover and a back cover and binding them together. In recent years, there has been known a ledger paper with a binding band wound around it to prevent the pages from being accidentally opened when an external force acts on it during movement. For example, there is known a structure in which a rectangular plate-like member is arranged on the back side of the front cover of a planner, and a wide rubber band member that can be stretched and contracted is fixed to the plate-like member by a rivet fitting (Patent Document 1). In this regard, when the user wraps the band member around the ledger paper, a strong tension is applied to the fixing portion of the band member. Therefore, it is necessary to adopt a strong fixing method such as a rivet fitting for fixing the band member.

Summary of the Invention
Problems to be Solved by the Invention
[0004] However, in the structure described in Patent Document 1, since the rubber band member is fixed by a rivet fitting, there is a problem that even when the band member is cut or the elastic force decreases due to repeated attachment and detachment, only the band member cannot be easily replaced. On the other hand, if the band member is designed to be easily detachable using engagement or the like, there is a problem that when the user wraps the band member around the ledger paper, the band member comes off the ledger paper due to the tension.
[0005] The inventors observed the actions of a user when using a ledger with a binding band. Specifically, when the user wraps the band member around the ledger, while one hand biases the ledger in the closing direction, the other hand wraps the band member around the ledger. Based on this observation, they found a structure for the binding band that can withstand the tension during this operation and can be easily attached to and detached from the ledger, thus completing the present invention.
[0006] The present invention has been made under such circumstances, and it is an object of the present invention to provide a binding band that functions as a book band despite its simple structure and can be easily attached to and detached from the ledger.
Means for Solving the Problems
[0007] In order to solve the above problems, the binding band according to the present invention is a binding band that temporarily maintains a closed state of a ledger formed by arranging a plurality of sheets between a front cover and a back cover and binding the back end. The binding band is formed of an elastically deformable material and includes a strip-shaped band portion, a pair of shaft bodies provided at both ends of the band portion in a direction orthogonal to the length direction of the band portion, and each provided at the tip of the shaft body pair of a locking piece. The locking piece includes a first locking piece provided in the length direction of the band portion from the tip of the shaft body, and a second locking piece provided in a direction opposite to the direction in which the first locking piece is provided from the tip of the shaft body. The binding band is formed in a two circular hole in the front cover or the back cover of the ledger, of the above locking pieces elastically deforms the first locking piece and the second locking piece to each pass through, and is attached to the ledger by inserting the shaft body into the hole. The band portion is elastically deformed and wrapped around the front cover or the back cover to which the binding band is not attached, and the binding band biases the front end of the ledger in the closing direction to temporarily maintain the closed state of the ledger (Claim 1).
[0008] When the user wraps the band portion around the book cover, while biasing the book cover in the closing direction with one hand, the user performs an operation of wrapping the band member around the book cover with the other hand. When in a state of being biased in the closing direction of the book cover, a clamping force acts on the locking piece including the first locking piece and the second locking piece of the binding band configured as described above between the back surface of the front cover and the front surface of the paper of page 1 (or between the back surface of the back cover and the back surface of the paper of the last page). This clamping force prevents the locking piece from being elastically deformed, and can prevent the locking piece from coming out of the hole even when a tension for pulling the band portion is applied by the user.
[0009] Also, while the binding band maintains the state of temporarily closing the book cover, due to the elastic force trying to return the binding band to its original state, the book cover is in a state of being biased in the closing direction, and a clamping force acts on the locking piece including the first locking piece and the second locking piece between the back surface of the front cover and the front surface of the paper of page 1 (or between the back surface of the back cover and the back surface of the paper of the last page). This clamping force prevents the locking piece from being elastically deformed, and can prevent the locking piece from coming out of the hole even when an elastic force trying to return the binding band to its original state is applied.
[0010] Also, since the first locking piece and the second locking piece of the locking piece are respectively provided in directions facing each other from the tip of the shaft body, it is possible to prevent the locking piece from coming out of the hole due to the tension or elastic force for pulling the band portion.
[0011] Therefore, according to the above binding band, it can sufficiently withstand the tension for pulling the band portion, and thus can function as a book band despite its simple structure.
[0012] Also, the above binding band can be attached to the book cover only by elastically deforming the first locking piece and the second locking piece and passing them through a circular hole formed in the front cover or the back cover of the book cover (hereinafter, when not particularly distinguished, referred to as the front cover, etc.), and inserting the shaft body into the hole. Also, the binding band attached to the book cover can be removed from the book cover only by elastically deforming the first locking piece and the second locking piece and passing them through the hole.
[0013] Further, by appropriately adjusting the height of the shaft body, the width of the gap formed between the band portion and the cover or the like can be adjusted according to the thickness of the cover of the ledger to be mounted. Therefore, by providing the shaft body, the gap generated between the band portion and the cover or the like can be adjusted to a minimum, so that it is possible to prevent the occurrence of convex portions or inclinations on the writing surface and the deterioration of the writability, and to prevent the damage caused by the rubbing between the band portion and the cover or the like.
[0014] Further, the shaft body is preferably formed in a cylindrical shape (Claim 2).
[0015] By configuring in this way, since the shaft body and the hole portion can be in line contact or surface contact, it is possible to prevent damage from occurring by receiving the tension in a dispersed manner.
[0016] Further, the locking piece is preferably formed in a plate shape (Claim 3).
[0017] By configuring in this way, since the locking piece can be in surface contact with the back surface of the cover and the front surface of the paper of one page (or the back surface of the back cover and the back surface of the paper of the last page), it becomes difficult to come out of the hole portion due to the tension or elastic force for pulling the band portion, and it is possible to prevent the occurrence of convex portions or inclinations on the writing surface and the deterioration of the writability.
[0018] Further, the ledger according to the present invention is characterized by including the binding band according to Claim 1 (Claim 4).
Effect of the Invention
[0019] According to the binding band of the present invention, it is configured as described above, functions as a book band despite its simple structure, and can be easily attached to and detached from the ledger.

FIGS. 4(a) and (b) show a front view (a) of the locking piece 3 in an elastically deformed state and a front view (b) of the locking piece 3 in a state where the binding band 1 is attached to the cover 11, respectively. The locking piece 3 is a plate-like body provided at the upper end (tip) of the shaft body 5. The locking piece 3 includes a first locking piece 3A provided in the right direction from the upper end (tip) of the shaft body 5 and a second locking piece 3B provided in the left direction, which is the opposite direction to the direction in which the first locking piece 3A is provided, from the upper end (tip) of the shaft body 5. The first locking piece 3A is a plate-like body formed in a substantially triangular shape in plan view with the apex angle arranged in the right direction (see particularly FIG. 2(c)). The second locking piece 3B extends leftward from the left end of the first locking piece 3A and is a plate-like body formed in a U-shaped with an opening on the left side in plan view (see particularly FIG. 2(c)).

The locking piece 4 is formed of a thermoplastic elastomer as described above and can be bent by elastic deformation when the user pinches it.
[0028] (Description of Notebook 10) Referring to FIGS. 5 and 6, the notebook 10 will be described. FIG. 5 and FIG. 6(a) show views of the notebook 10 as seen from the cover 11 side. FIG. 6(b) shows a view of the notebook 10 as seen from the back cover 12 side. The notebook 10 is, for example, a notebook formed by arranging a plurality of sheets of the same type between a thick cover 11 and a thick back cover 12, binding the back end, and making the front end openable and closable. Regarding the directions for explaining the notebook 10, as shown in FIG. 4, with the cover 11 as the front, the left side is the back end, the right side is the front end, the upper side is the upper end, and the lower side is the lower end.
[0029] As shown in FIGS. 5 and 6(a), on the cover 11 of the notebook 10, a total of two circular holes 13 and 14 are formed at upper and lower positions on the front end side and at the same distance from the front end. As shown in FIG. 4, the diameters of the holes 13 and 14 are smaller than the length of the locking pieces 3 and 4 in the left-right direction, and are formed to have a length that allows the locking pieces 3 and 4 bent by elastic deformation to pass through and the shaft bodies 5 and 6 to be loosely fitted.
[0030] (Description of Attachment and Detachment of Binding Band 1 to Notebook 10) Referring to FIGS. 4 and 5, the attachment of the binding band 1 to the notebook 10 will be described. FIG. 4(a) shows a mode in which the locking piece 3 of the binding band 1 is elastically deformed and passed through the hole 13 formed in the cover 11 of the notebook 10. FIG. 4(b) shows a mode after the elastic deformation of the locking piece 3 is released after passing through the hole 13. FIG. 5 shows a front view of the binding band 1 attached to the notebook 10. First, as shown in FIG. 4(a), the user sandwiches and elastically deforms the first locking piece 3A and the second locking piece 3B that constitute the locking piece 3 of the binding band 1. Next, with the locking piece 3 elastically deformed, it is passed through the hole 13 formed in the cover 11 of the notebook 10. Next, as shown in FIG. 4(b), with the shaft body 5 of the binding band 1 inserted into the hole 13, the elastic deformation of the locking piece 3 is released. Next, in the same procedure as the attachment of the locking piece 3, the locking piece 4 is attached to the hole 14 (not shown). Thus, the attachment of the binding band 1 to the notebook 10 is completed.
[0031] When removing the binding band 1 from the ledger, if the locking pieces 3 and 4 are elastically deformed and passed through the holes 13 and 14, it can be removed from the ledger 10. Thus, the binding band 1 according to the present invention can be easily attached to and detached from the ledger 10.
[0032] (Explanation of the restraint of the front end of the ledger 10 by the binding band 1) Referring to FIGS. 5 and 6, the restraint of the front end of the ledger 10 by the binding band 1 will be described. FIG. 5 shows a view of the cover 11 side with the binding band 1 attached to the ledger 10, and a conceptual diagram of a state where the band portion 2 is stretched by elastic deformation when the user pulls it. FIG. 6(a) shows a view seen from the cover 11 side of the ledger 10 whose front end is restrained by the binding band 1. FIG. 6(b) shows a view seen from the back cover 12 side of the ledger 10 whose front end is restrained by the binding band 1. First, the user holds the ledger 10 with one hand and pinches the band portion 2 with the other hand. Next, the band portion 2 is pulled to stretch it by elastic deformation, and the band portion 2 is wound around the back cover 12, the upper end, and the lower end of the ledger 10 (see FIG. 5). If the band portion 2 is elastically deformed and wound around the back cover 12, the upper end, and the lower end of the ledger 10, the binding band 1 is biased in the direction of closing the front end of the ledger 10 by the elastic force, so that the ledger 10 can be temporarily maintained in a closed state. Thus, the restraint of the front end of the ledger 10 by the binding band 1 is completed.
[0033] When the user winds the band portion 2 around the ledger 10, while biasing the ledger 10 in the closing direction with one hand, the user performs an operation of winding the band portion 2 around the ledger 10 with the other hand. When the ledger 10 is biased in the closing direction, a force that sandwiches the locking pieces 3 and 4 having the first locking pieces 3A and 4A and the second locking pieces 3B and 4B acts between the back surface of the cover 11 and the front surface of the paper of one page. This sandwiching force prevents the locking pieces 3 and 4 from being elastically deformed, and can prevent the locking pieces 3 and 4 from coming out of the holes 13 and 14 even when a tension for pulling the band portion 2 is applied by the user.
[0034] Also, while the binding band 1 maintains the state of closing the ledger 10, due to the elastic force attempting to return the binding band 1 to its original position, the ledger 10 is in a state of being biased in the closing direction, and a force that sandwiches the locking pieces 3, 4 having the first locking pieces 3A, 4A and the second locking pieces 3B, 4B acts between the back surface of the cover 11 and the front surface of the paper of one page. This sandwiching force prevents the locking pieces 3, 4 from elastically deforming, and even when the elastic force attempting to return the binding band 1 to its original position is applied, it is possible to prevent the locking pieces 3, 4 from coming out of the holes 13, 14.
[0035] Also, since the first locking pieces 3A, 4A and the second locking pieces 3B, 4B are respectively provided in directions facing each other from the tips of the shaft bodies 5, 6, it is possible to prevent the locking pieces 3, 4 from coming out of the holes 13, 14 due to the tension or elastic force that pulls the band portion 2.
[0036] Therefore, according to the binding band 1, it can sufficiently withstand the tension and elastic force that pull the band portion 2, so it can function as a book band despite its simple structure.
[0037] When elastically deforming the band portion 2 and winding it around the ledger 10, since the heights of the shaft bodies 5, 6 are appropriately adjusted, by minimizing the gap generated between the band portion 2 and the cover 11, it is possible to prevent convex portions and inclinations from occurring on the writing surface and prevent the writing performance from deteriorating, and it is also possible to prevent damage due to rubbing between the band portion 2 and the cover 11.
[0038] When elastically deforming the band portion 2 and winding it around the ledger 10, the shaft bodies 5, 6 are formed in a cylindrical shape, and the shaft bodies 5, 6 and the holes 13, 14 of the ledger 10 can be in line or surface contact, so it is possible to prevent damage from occurring by dispersing and receiving the tension.
[0039] Further, by forming the first locking pieces 3A and 4A and the second locking pieces 3B and 4B in a plate shape, the locking pieces 3 and 4 can be in surface contact with the back surface of the cover 11 and the front surface of the paper surface of page 1. As a result, it becomes difficult for the locking pieces to come out of the holes 13 and 14 due to the tension or elastic force applied to pull the band portion 2, and it is possible to prevent the occurrence of convex portions or inclinations on the writing surface and the deterioration of the writability.
[0040] Thus, according to the binding band 1 of the present invention, despite its simple structure, it functions as a book band and can be easily attached to and detached from the ledger 10. (Description of other embodiments)
[0041] In the above-described embodiment, as shown in FIG. 6, the band portion 2 was wound around the back cover 12, the upper end, and the lower end of the ledger 10, but it may be wound around the back cover 12. For example, as shown in FIG. 7, claws 15 may be formed on the back cover 12A of the ledger 10A to catch the band portion 2. Even with this configuration, the binding band 1 can be biased in the direction of closing the front end of the ledger 10A.
[0042] In the above-described embodiment, as shown in FIG. 5, a total of two holes 13 and 14 were formed at the upper and lower positions on the front end side of the cover 11 of the ledger 10 and at the same distance from the front end, but they do not necessarily have to be formed at this position. For example, as shown in FIG. 8, a total of two holes 16 and 17 may be formed at the left and right positions on the lower end side of the cover 11B of the ledger 10B and at the same distance from the lower end. Even with this configuration, by winding the band portion 2 around the back cover 12, the back end, and the front end of the ledger 10B, the binding band 1 can be biased in the direction of closing the front end of the ledger 10B.
[0043] In the above-described embodiment, as shown in FIG. 2, for the locking pieces 3 and 4, the first locking pieces 3A and 4A are formed as plate-like bodies having a substantially triangular shape in plan view, and the second locking pieces 3B and 4B are formed as U-shaped plate-like bodies. However, the shapes of the locking pieces 3 and 4 are arbitrary, and they may be formed in a shape as shown in FIG. 9, for example. FIGS. 9(a) and (b) show a rear view (a) of the locking pieces 7 and 8 and an enlarged rear view (c) of the locking piece 7. The locking pieces 7 and 8 include first locking pieces 7A and 8A provided at the upper ends of the shaft bodies 5 and 6, and second locking pieces 7B and 8B provided in a direction opposite to the direction in which the first locking pieces 7A and 8A are provided from the upper ends of the shaft bodies 5 and 6. The first locking pieces 7A and 8A are plate-like bodies formed in a substantially rectangular shape in plan view. The second locking pieces 7B and 8B are plate-like bodies extending from the ends of the first locking pieces 7A and 8A and formed in a substantially rectangular shape in plan view. Even the binding band 1A formed with the locking pieces 7 and 8 as described above can be attached to and detached from the ledger 10 in the same procedure as the above-described binding band 1, and can be biased in a direction to close the front end of the ledger 10.
[0044] The present invention is not limited to the examples of the above-described embodiments and examples, and various design-changed forms are included within the technical scope of the claims without departing from the gist of the invention.
