Patent document 1: CN101983136B

In the binding tool of patent document 1, in order to unlock the lock, that is, in order to open the closed loop, all the loop pieces on both the left and right sides need to be moved in opposite directions in the longitudinal direction. However, in actual use, it is not easy to move only the left and right ring pieces in the longitudinal direction, and it is necessary to move the cover so that all the left and right ring pieces move in opposite directions in the longitudinal direction together with the cover. Therefore, in order to open the left and right loop pieces, the cover must be opened, which complicates the operation. In particular, it is not easy for a user who uses the binding tool for the first time to get on his hand. Therefore, it is necessary to provide a binding tool which is simple in unlocking operation.

Disclosure of Invention

The invention provides a binding tool with simple unlocking operation.

A binding tool for binding an object to be bound, the binding tool having a plurality of holes arranged at a predetermined pitch, the binding tool comprising: a first base portion and a second base portion extending in a first direction; a non-lock ring portion including a plurality of non-lock rings, each of the plurality of non-lock rings including a plurality of first ring pieces arranged at an arbitrary position on the first base portion at the predetermined pitch, and a second ring piece provided on the second base portion so as to be openable and closable with respect to the first ring piece, the first ring piece and the second ring piece not engaging with each other in a closed state; and a lock ring portion including a pair of lock rings, the pair of lock rings including a first lock ring piece disposed at the first base portion at a distance N times (N is a natural number) the predetermined pitch, and a second lock ring piece provided at the second base portion so as to be openable and closable with respect to the first lock ring piece, the first lock ring piece and the second lock ring piece being engageable with each other in a closed state, the pair of lock rings being disposed at a distance larger than the predetermined pitch from the adjacent non-lock rings. Since the binding tool has the non-locking ring portion and the locking ring portion, only the locking ring of the locking ring portion is locked in the closed state, and a gap larger than a predetermined pitch is provided in front of the locking ring and the non-locking ring portion. Therefore, it is easy to insert a finger into the gap to release the engagement of the locking ring, and the unlocking operation is simplified.

Preferably, the pair of locking rings of the locking ring portion is configured to release the engagement in the closed state by moving one of the locking first ring pieces and the other locking first ring piece in a direction to approach each other. Therefore, when unlocking, for example, the two locking rings can be pinched by the thumb and the index finger and moved in the direction of approaching each other, and the locking can be easily unlocked.

Preferably, the one locking first ring piece and the other locking first ring piece are moved in a direction to approach each other by elastic deformation caused by an external force. Since the locking ring is elastically deformed to release the lock, it is possible to realize the lock without adding a new member or changing the structure, and the structure of the present invention can be simplified.

Preferably, the first locking ring piece and the second locking ring piece are elastically biased in a direction to be opened when engaged in the closed state. Since the locking ring is elastically biased in the opening direction when engaged in the closed state, when the locking of the locking ring is released, the locking ring is brought into the open state by the elastic force, and it is not necessary to separately provide a member such as a spring for bringing the locking ring into the open state.

Preferably, the first locking ring piece and the second locking ring piece are separated from each other at their distal ends in a free state when the first ring piece and the second ring piece are in a closed state, and are elastically deformed in directions approaching each other by an external force to be engaged with each other.

Preferably, the pair of locking rings are disposed adjacent to each other. Since the locking rings are disposed adjacent to each other, the locking rings can be easily manipulated during operation.

Preferably, the first locking ring piece and the second locking ring piece have hook portions at distal ends thereof, which engage with each other, and the first ring piece and the second ring piece of the non-locking ring portion extend in a second direction intersecting the first direction and have overlapping portions with which side surfaces thereof can abut against each other. Thus, the binder body is prevented from being sandwiched between the pair of ring pieces because the non-locking rings are overlapped.

Preferably, the lock ring portions are provided at both ends of the first base portion and the second base portion in the first direction, and the non-lock ring portion is provided so as to be sandwiched between the lock ring portions at both ends.

Preferably, the first locking ring piece and the second locking ring piece are formed so as to be distinguishable from each other. Since both can be distinguished from each other, the ring piece to be operated is easily known when unlocking is performed, and the unlocking operation is simplified.

Preferably, the first locking ring piece and the second locking ring piece are different in color. Since the colors are different, the ring piece to be operated can be found at a glance when the lock is released, and the operation of releasing the lock becomes easy.

Preferably, the non-locking ring and the locking ring are shaped to allow the bound object to be rotated 360 degrees. By applying such a structure to the present invention, the locking operation of the binding tool can be made simpler.

Preferably, the first base part and the second base part are coupled to each other so as to be rotatable in a direction in which the first ring piece and the second ring piece open and close. The above structure is simpler than a structure in which the ring segments are rotatably coupled to the respective base portions.

Preferably, the first base portion, the first ring piece, and the first locking ring piece are integrally molded, the first ring piece and the first locking ring piece have a flat first bottom portion extending from the first base portion in the second direction, and a first body portion extending upward from the first bottom portion and having a front end portion extending toward the second ring piece, the second base portion, the second ring piece, and the second locking ring piece are integrally molded, and the second ring piece and the second locking ring piece have a flat second bottom portion extending from the second base portion in the second direction away from the first bottom portion, and a second body portion extending upward from the second bottom portion and having a front end portion extending toward the first ring piece. According to the structure, the bound object such as the cover and the loose-leaf paper can be easily rotated by 360 degrees.

According to the present invention, a binding tool with a simple unlocking operation can be provided.

Detailed Description

An embodiment of the present invention will be described below with reference to the drawings. The binding tool T of the present embodiment is a member for binding a bound object such as loose-leaf paper having a plurality of holes arranged at a predetermined pitch, and can rotate a cover 360 degrees to overlap a back cover.

As shown in fig. 1, the binding tool T includes a first base part 1, a second base part 2, an unlocked ring part F, a locked ring part L, and a shaft part 5 (not shown). In the present embodiment, the longitudinal direction of the first and second base parts 1 and 2 is set as the first direction.

As shown in fig. 3, the first base 1 includes a first base body 11 and a first connecting portion 12, and the first connecting portion 12 is formed with a recess and a hole through which the shaft portion 5 passes. The second base 2 has a second base body 21 and a second coupling portion 22, and the second coupling portion 22 has a recess and a hole for the shaft 5 to pass through. The first base part 1 and the second base part 2 are rotatably coupled together by inserting the shaft part 5 through the grooves and holes formed in the first coupling part 12 and the second coupling part 22.

The non-locking ring portion F is constituted by a plurality of non-locking rings 3, and since the non-locking rings 3 have a plurality, only one pair is representatively labeled in the drawings. As shown in fig. 1 and 4, a plurality of first ring pieces 31 are formed at a predetermined pitch on the first base part 1. The predetermined pitch corresponds to the pitch of holes in the bound material such as a cover and a loose-leaf paper. The non-locking ring 3 is formed by a first ring plate 31 formed in the first base part 1 and a second ring plate 32 formed in the second base part 2. The first ring piece 31 has a first bottom portion 311 coupled to the first base portion 1 and a first body portion 312. The first bottom portion 311 extends flatly from the first base portion 1 in a direction perpendicular to the first direction. The first body 312 extends upward from the first bottom 311 and has an end extending toward the second ring 32. An overlapping portion 313 is formed at the front end of the first body portion 312, the overlapping portion 313 is formed such that the width in the first direction from the portion connected to the first body portion 312 gradually becomes narrower from the portion connected to the first body portion 312 to the end portion, and arc-shaped chamfers are formed at the connecting portion to the first body portion 312 and the end portion. The second ring piece 32 has the same structure and arrangement as the first ring piece 31, including the second bottom 321, the second body 322, and the overlapping portion 323, and thus detailed description thereof is omitted. As shown in fig. 1 and 4, since the overlapping portion 313 and the overlapping portion 323 overlap with each other in the closed state, and the overlapping portion 313 and the overlapping portion 323 form a slope and are chamfered, the ring is not easily caught during opening and closing, and the ring can be smoothly opened and closed, that is, the first ring piece 31 and the second ring piece 32 are not engaged with each other. In the present invention, the non-engagement means that the first ring piece and the second ring piece in the closed state can be easily brought into the open state when an external force in a direction of separating from each other is applied to the first ring piece and the second ring piece.

The locking ring portion L in the present embodiment has four locking rings 4, is divided into two groups of two rings, and is located at each end of the binding tool T. The two sets of locking rings 4 are spaced apart from the non-locking ring portion F by a predetermined distance twice as much, and since the two sets of locking rings 4 have the same structure and arrangement, only one pair of locking rings 4 will be described.

The two locking rings 4 are provided at a predetermined interval. The locking ring 4 includes a first locking ring piece 41 formed on the first base part 1 and a second locking ring piece 42 formed on the second base part. The first locking ring piece 41 has a first locking bottom part 411, a first locking body part 412, and a locking hook 413. The first locking bottom portion 411 extends flatly from the first base portion 1 in a direction perpendicular to the first base portion 1. The first locking body 412 extends upward from the first locking bottom 411 and has an end extending toward the second locking ring 42. A locking hook 413 is formed at the front end of the locking first body 412. The locking hook 413 has a concave portion on a side close to the locking first body part 412 and a convex portion at an end portion, thereby forming an engaging structure having a substantially R-shape in plan view.

The locking second ring piece 42 has a locking second bottom 421, a locking second body 422, and a locking hook 423, similarly to the locking first ring piece 41. The locking second bottom 421 extends flat from the second base part 2 in a direction perpendicular to the second base part 1. The locking second body portion 422 extends upward from the first bottom portion 421 and has an end portion extending toward the locking first ring piece 41. A locking hook 423 is formed at the front end of the locking second body 422. The locking hook 423 has a projection and a recess as in the locking hook 413, but the orientations are opposite, so that the locking hook 423 and the locking hook 413 can be fitted to each other. As shown in fig. 4, in the two first locking ring pieces 41, the locking hook 413 of one first locking ring piece is disposed such that the projection and the recess face leftward in the figure, and the locking hook 413 of one first locking ring piece is disposed such that the projection and the recess face rightward in the figure. Since the first locking ring piece 41 is elastically deformable in the longitudinal direction of the base portion, the closed locking state can be released by pressing the first locking ring piece 41.

As shown in fig. 1 and 6, the lock ring portion L is in a closed self-contained state in which it is not subjected to an external force, and the tips of the first ring piece 41 for locking formed in the first base portion 1 and the second ring piece 42 for locking formed in the second base portion are in a state in which they are separated from each other and are not engaged with each other. Fig. 7 is a schematic view showing the first locking ring piece 41. In the case where the external force is not applied in the unlocked state, the first locking ring piece 41 is maintained in the original state as shown by the solid line in fig. 7. In the locked state, the first locking tab 41 is engaged with the second locking tab 42 against its own elastic force by receiving an external force, and the locking hook 413 and the locking hook 423 are kept in the engaged state, thereby forming a shape shown by a broken line in fig. 7. In the present invention, the engagement means that the first locking ring piece and the second locking ring piece are locked, and in the closed state, even if the first locking ring piece and the second locking ring piece are pulled in directions of separating from each other, the first locking ring piece and the second locking ring piece cannot be in the open state. At this time, the first locking ring piece 41 and the second locking ring piece 42 are elastically deformed and elastically biased in the direction of opening. The locking second ring piece 42 has the same structure, and a detailed description thereof is omitted. Since the first locking ring piece 41 and the second locking ring piece 42 have the above-described configuration, the locking hook 413 and the locking hook 423 are constantly subjected to the above-described elastic force in the locked state, and the locked state can be maintained more stably. When the locking is released, the first locking ring piece 41 and the locking ring piece 42 automatically become the closed and unlocked state shown in fig. 1 and 6 when the locking hook 413 and the locking hook 423 are released due to the elastic force, and this operation is realized without providing a separate member, thereby simplifying the structure of the binder T.

In the closed state, the non-locking ring portion F and the locking ring portion L form a closed ring, and the cover or the like can be rotated 360 degrees in the ring, so that the cover and the used loose-leaf paper can be overlapped with the back cover, and the usage mode and usage scenario of the binder using the binding tool of the present embodiment can be increased.

In the present embodiment, the first base portion 1, the plurality of first ring pieces 31, and the four locking first ring pieces 41 are integrally molded with resin, and the entire integrally molded member is referred to as a first portion a, and the second base portion 2, the plurality of second ring pieces 32, and the four locking second ring pieces 42 are integrally molded with resin, and the entire integrally molded member is referred to as a second portion B. In order to allow the user to easily recognize the first locking ring piece 41, the first part a and the second part B may be formed using different colored resins. That is, the first locking ring piece 41 and the second locking ring piece 42 are different in color, and the user can distinguish the first locking ring piece 41 and the second locking ring piece 42 at a glance, thereby improving convenience in operation and improving operation efficiency.

Next, an operation method of the binding tool T of the present embodiment will be described. The operation of unlocking will be explained first. When unlocking, the user simply presses the two first locking ring pieces 41 with two fingers and moves them in the direction in which they approach each other by elastic deformation, thereby disengaging the locking hooks 413 of the two first locking ring pieces 41 from the locking hooks 423 of the two second locking ring pieces 42. At this time, since the first locking ring piece 41 and the second locking ring piece 42 are elastically deformed and elastically urged in the direction of opening, when the locking hook 413 and the locking hook 423 are disengaged, the first locking ring piece 41 and the second locking ring piece 42 are automatically separated by the elastic urging force. Thus, the lock can be released by one operation of pressing the two first locking ring pieces 41, and the operation is very simple and efficient. In addition, since the two groups of locking ring portions L are located at both ends, the two groups of locking ring portions L can be operated with both hands at the same time, thereby further simplifying the operation and improving the efficiency.

Next, an operation of locking the binding tool T will be described, and in the open state shown in fig. 3, the first part a and the second part B are rotated to be close to each other, and the closed state shown in fig. 1 is obtained, and at this time, the locking ring portion L is slightly biased from both sides, and the binding tool T is locked while overcoming the elastic force of the locking ring 4 itself and the resistance between the locking hook 413 and the locking hook 423, and the closed locked state shown in fig. 2 is obtained. As in the case of the unlocking operation, the two groups of lock ring portions L can be operated by both hands at the same time, thereby simplifying the operation and improving the efficiency.

While the embodiments of the present invention have been described above, the specific configurations of the respective portions are not limited to the above-described embodiments, and various modifications and changes can be made without departing from the spirit of the present invention.

In the above embodiment, a case where two locking rings are adjacent to each other is described, but the present invention is not limited to this, and one non-locking ring may be disposed between the two locking rings as shown in fig. 8, for example. This can increase the distance between the two locking rings, facilitating handling by a large-handed user.

In the above-described embodiment, the structure of the locking hook portion has been described, but the present invention is not limited to this, and any structure may be used as long as it can stably lock and smoothly release the lock by pressing.

The gap between the non-locking ring portion F and the locking ring portion L is not particularly limited and may be adjusted according to the actual use. However, for ease of operation, the gap is preferably large to facilitate operation by the user.

In the present embodiment, the non-locking ring portions F are disposed at the central portion in a concentrated manner, but the present invention is not limited thereto, and the non-locking ring portions F may be disposed at two locations. The number of locking rings and non-locking rings of the binding tool of the present invention is not limited to the above embodiment, and can be changed flexibly according to the size of the bound object.

The method for identifying the first ring piece and the second ring piece is not limited to identifying by different colors, and may be easily identified by other methods such as changing the shape and material. For example, the surface of one of the first ring piece and the second ring piece can be a frosted surface, so that a user can recognize the first ring piece and the second ring piece by touch, and the use is more convenient.

In the above embodiment, the case where the binding tool T is rotated by the shaft portion 5 has been described, but the rotation may be performed by providing the first base portion 1 and the second base portion 2 with the convex portion and the concave portion and fitting the convex portion and the concave portion without using the shaft portion 5.

The present invention can be used as a binding tool capable of binding and fixing sheet-like articles.
